Cliffs Natural Resources Inc. is a leading mining and natural resources 

company  in  the  United  States.  The  Company  is  a  major  supplier  of 

iron ore pellets to the North American steel industry from its mines and 

pellet processing facilities located in Michigan and Minnesota. Cliffs also 

operates an iron ore mining complex in Western Australia. 

As  a  differentiated  mining  company,  Cliffs  Natural  Resources  Inc.  is 

uniquely  positioned  to  satisfy  the  requirements  of  our  steelmaking 

customers.   Our high-grade, premium pellets are customized for and fed 

directly to our customers’ blast furnaces.

Driven  by  the  core  values  of  safety,  social,  environmental  and  capital 

stewardship,  Cliffs  employees  endeavor  to  provide  all  stakeholders 

operating and financial transparency.

MESSAGE 
FROM THE CEO

Dear Fellow Shareholder:

2015  was  a  momentous  year  for  Cliffs.    We  made  several 
crucial  decisions  aimed  at  strengthening  the  Company,  our 
balance sheet and our core U.S. iron ore business. We have 
not veered from our U.S. based strategy which is predicated 
on  one  fundamental  fact:  China’s  steel  demand  is  actually 
shrinking,  not  growing.    During  one  of  the  most  demanding 
environments  for  global  iron  and  domestic  steel  in  over  a 
decade, we accomplished all that we set out to do and enter 
2016 as a refocused and re-energized company.  

Throughout  2015,  our  focus  on  cost  reduction,  operating 
efficiencies  and  optimizing  cash  flow  drove  solid  results, 
despite  depressed  iron  and  steel  prices.  Our  operating 
teams  delivered 
lower  production  costs  and  profitable 
margins  across  all  continuing  operations.  Full-year  capital 
expenditures and SG&A spending were reduced to levels not 
seen in many years at Cliffs. Most importantly, the discipline 
and  cost  focus  of  our  operating  teams  did  not  come  at  the 
expense of two non-negotiable values of our company: safety 
and environmental stewardship.  

In contrast to many other players in the industry, we did achieve 
our  non-core  asset  divesture  objectives.  A  very  important 
component of our strategy was the complete divestiture of our 
North American Coal business. We ended the year 2014 on a 
high note having completed the sale of Logan County Coal for 
$174 million in cash and the assumption of certain liabilities. 
In  a  very  similar  fashion,  we  finished  2015  by  selling  the 
Pinnacle and Oak Grove mines in a transaction valued at $268 
million  based  on  the  buyer  assuming  substantially  all  of  the 
liabilities of that business. Within Canada, we initiated formal 
restructuring  proceedings  under  the  Companies’  Creditors 

Arrangement Act (Canada) (“CCAA”) for the Bloom Lake and 
Wabush  mines.    We  made  substantial  progress  with  these 
assets. By year-end, an asset purchase agreement to acquire 
the  Bloom  Lake  mine,  some  mineral  claims  and  related  rail 
assets  was  executed  and  has  recently  been  approved  by 
the CCAA Court. In 2015, we also completed the sale of our 
Chromite  assets  in  Northern  Ontario  as  part  of  the  CCAA 
process. We also finalized the sale of the Decar Nickel project 
in British Columbia and the remaining portfolio of exploration 
projects. Each transaction represents a very important step in 
implementing our U.S. iron ore pellet-centric strategy. 

In  the  U.S.,  the  domestic  steel  industry  was  hampered  by 
historic levels of unfairly traded steel imports which weakened 
our  customers’  demand  for  pellets.  We  worked  very  well 
throughout the year to implement a production plan to adjust to 
our customers’ reduced requirements.  Looking more broadly 
at Cliffs’ market position in the U.S., certain competitive threats 
that were emerging have all but faded away over the past year. 
Moving forward, our competitive position in the Great Lakes 
region is stronger than ever before.

While  we  are  still  in  the  early  stages  of  developing  our  DR-
grade  pellet  business,  we  are  very  optimistic  about  tapping 
into a new market segment as a future supplier to EAF steel 
producers.  Using  our  technical  expertise  to  increase  our 
product  offering,  we  are  excited  about  our  new  business 
opportunity as a supplier of DR-grade pellets to DRI producers. 
At  this  stage,  we  have  reached  a  significant  milestone  with 
very positive results from the successful operational trial of our 
DR-grade pellets.

Roadmap to 
Future Financial 
Success

Our roadmap to our future 
financial success is simple 
and actionable. 

We will:

•  Maintain our non-stop 

focus on cost reduction 

•  Use our technical 

expertise and strong 
market position in 
the U.S. to increase 
our product offering 
and foster improved 
profitability 

•  Continue to pursue debt 
reduction opportunities. 

One of the most important achievements for the year was the refinancing of Cliffs 
in  the  face  of  a  very  difficult  debt  market  for  the  mining  industry.  A  significant 
undertaking during the first quarter of 2015, we captured available market discounts 
on our various bonds to reduce our net debt through a second lien debt exchange 
offer, removed the onerous financial covenants tied to our old revolving credit facility 
by  replacing  it  with  a  new  asset-based  lending  facility,  and  we  completed  a  first-
lien  note  offering  that  netted  us  nearly  $500  million  dollars  in  cash.  Also  during 
the year, we took advantage of the opportunities offered by the debt markets and 
completed a cash tender offer for our senior notes which significantly reduced our 
nearest-dated debt maturity and associated future interest payments. Through these 
liability management exercises, we reduced net debt by nearly $200 million dollars. 
Additionally during the first quarter of this year, we launched an exchange offer to 
replace approximately $512 million of existing indebtedness with new 1.5 lien bonds.  
This debt exchange alone will reduce debt by $293 million and lower interest expense 
by $14 million during very difficult financial market situations.

Our roadmap to our future financial success is simple and actionable. We will:

•  maintain our non-stop focus on cost reduction; 
•  use our technical expertise and strong market position in the U.S. to increase 

our product offering and foster improved profitability; and 

•  continue to pursue debt reduction opportunities. 

On behalf of the Board of Directors, I want to thank the entire Cliffs’ team for their 
continued commitment and dedication to the Company. We also thank our partners, 
customers, rail providers, shipping companies and the United Steelworkers for their 
cooperation as we made difficult, but necessary decisions related to our production 
plans to respond to evolving market conditions. 

Last, but for sure not least, I would like to take this opportunity to thank all of you, 
my  fellow  shareholders,  for  your  unwavering  support  as  we  took  the  bold  steps 
necessary  in  pursuit  of  our  strategy.  We  know  we  have  more  work  to  do  and  our 
management team is fully committed to get the job done. I am grateful for your far-
sighted investment in our great Company and your continued trust in Cliffs.

Sincerely,

Lourenco Goncalves

Business

Introduction

PART I

Cliffs Natural Resources Inc. traces its history back to 1847.  Today, we are a leading mining and natural resources 
company in the United States.  We are a major supplier of iron ore pellets to the North American steel industry from our 
mines and pellet plants located in Michigan and Minnesota.  Additionally, Cliffs operates an iron ore mining complex in 
Western Australia.  Driven by the core values of safety, social, environmental and capital stewardship, our employees 
endeavor to provide all stakeholders with operating and financial transparency.  

We are organized through a global commercial group responsible for sales and delivery of our products and  
operations groups responsible for the production of the iron ore that we market.  Our continuing operations are organized 
according to geographic location: U.S. Iron Ore and Asia Pacific Iron Ore.

In the U.S., we currently own or co-own five iron ore mines in Michigan and Minnesota.  We are currently operating 
the two iron mines in Michigan and one of the three iron ore mines in Minnesota. Two of our three iron ore operations in 
Minnesota are temporarily idled due to reductions in iron ore pellet nominations from our customers due to the continued 
oversupply of steel in the U.S. market as a result of record levels of imported steel which stems from excess supply in 
the global markets.  Our Asia Pacific operations consist solely of our Koolyanobbing iron ore mining complex in Western 
Australia.  

Also, for the majority of 2015, we operated two metallurgical coal operations in Alabama and West Virginia.  In 
December 2015, we completed the sale of these operations, which marked our exit from the coal business.   As of March 
31, 2015, management determined that our North American Coal operating segment met the criteria to be classified as 
held for sale under ASC 205, Presentation of Financial Statements.  As such, all current year and historical North American 
Coal operating segment results are included in our financial statements and classified within discontinued operations. 
Refer  to  NOTE  14  -  DISCONTINUED  OPERATIONS  for  further  discussion  of  the  North  American  Coal  segment 
discontinued operations.

Additionally,  we  continue  to  own  two  non-operating  iron  ore  mines  in  Eastern  Canada  that  are  currently  in 
restructuring proceedings in Montreal, Quebec, under the CCAA. The CCAA filing related to our Eastern Canadian Iron 
Ore operations is more fully described below in the Business Segments section and in NOTE 14 - DISCONTINUED 
OPERATIONS.  Financial results prior to the respective deconsolidations of the Bloom Lake and Wabush Groups and 
subsequent expenses directly associated with the Bloom Lake Group, Wabush Group and certain other wholly-owned 
subsidiaries  (collectively,  the  "Canadian  Entities")  are  included  in  our  financial  statements  and  classified  within 
discontinued operations. 

Unless otherwise noted, discussion of our business and results of operations in this Annual Report on Form 10-

K refers to our continuing operations.

The Company is Focused on our Core U.S. Iron Ore Business

We continue to execute the strategy that was established in 2014, which focuses on becoming a company fully 
centered on our U.S. Iron Ore business.  We are the market-leading iron ore producer in the U.S., supplying differentiated 
iron ore pellets under long-term contracts, some of which begin to expire in December 2016, to the largest North American 
steel producers.  Cliffs has the unique advantage of being a low cost producer of iron ore pellets in the U.S. market with 
significant transportation and logistics advantages to effectively serve the U.S. steel market.  Pricing structures contained 
in and the long-term supply provided by our existing contracts, along with our low-cost operating profile, positions U.S. 
Iron Ore as our most stable business.  We expect to continue to strengthen our U.S. Iron Ore cost operating profile 
through continuous operational improvements and disciplined capital allocation policies.  Strategically, we continue to 
develop various entry options into the EAF market.  As the EAF steel market continues to grow in the U.S., there is an 
opportunity for our iron ore to serve this market by providing pellets to the alternative metallics market to produce direct 
reduced iron pellets, hot briquetted iron and/or pig iron.  In 2015, we produced and shipped a batch trial of DR-grade 
pellets, a source of lower silica iron units for the production of direct reduced iron pellets.  In early 2016, we reached a 
significant milestone with positive results from the successful industrial trial of our DR-grade pellets.  While we are still 
in the early stages of developing our alternative metallic business, we believe this will open up a new opportunity for us 
to diversify our product mix and add new customers to our U.S. Iron Ore segment beyond the traditional blast furnace 
clientele.

Business Segments

Our Company’s continuing operations are organized and managed according to geographic location: U.S. Iron 

Ore and Asia Pacific Iron Ore. 

Segment information reflects our business units, which are organized to meet customer requirements and global 
competition.  We have historically evaluated segment performance based on sales margin, defined as revenues less 
cost of goods sold, and operating expenses identifiable to each segment.  Additionally, beginning in the third quarter of 
2014, concurrent with the change in control on July 29, 2014, management began to evaluate segment performance 
based on EBITDA, defined as net income (loss) before interest, income taxes, depreciation, depletion and amortization, 
and Adjusted EBITDA, defined as EBITDA excluding certain items such as impairment of goodwill and other long-lived 
assets, impacts of discontinued operations, extinguishment of debt, severance and contractor termination costs and 
other costs associated with the change in control, foreign currency remeasurement, certain supplies inventory write-offs, 
and intersegment corporate allocations of selling, general and administrative costs.  Management uses and believes 
that investors benefit from referring to these measures in evaluating operating and financial results, as well as in planning, 
forecasting and analyzing future periods as these financial measures approximate the cash flows associated with the 
operational earnings.  Financial information about our segments, including financial information about geographic areas, 
is included in Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations and NOTE 
2 - SEGMENT REPORTING included in Item 8. Financial Statements and Supplementary Data of this Annual Report on 
Form 10-K.

U.S. Iron Ore 

We are a major producer of iron ore pellets, primarily selling production from U.S. Iron Ore to integrated steel 
companies in the U.S. and Canada.  We manage five iron ore mines located in Michigan and Minnesota.  In Michigan, 
we are currently operating the two iron ore mines, Empire mine and Tilden mine. In Minnesota, we are currently operating 
one iron ore mine, Hibbing mine.  The other two iron ore operations in Minnesota, United Taconite mine and Northshore 
mine, are temporarily idled due to reduced pellet demand from our customers.  The idling of United Taconite mine began 
during August 2015 and the idling of Northshore mine began at the end of November 2015.  Both mines are expected 
to be idled through at least the first quarter of 2016.  The U.S.-based mines currently have an annual rated capacity of 
32.9 million tons of iron ore pellet production, representing 56 percent of total U.S. pellet production capacity.  Based on 
our equity ownership in these mines, our share of the annual rated production capacity is currently 25.5 million tons, 
representing 44 percent of total U.S. annual pellet capacity.

The following chart summarizes the estimated annual pellet production capacity and percentage of total U.S.

Our  U.S.  iron  ore  production  generally  is  sold  pursuant  to  long-term  supply  agreements  with  various  price 
adjustment provisions.  For the year ended December 31, 2015, we produced a total of 26.1 million tons of iron ore 
pellets, including 19.3 million tons for our account and 6.8 million tons on behalf of steel company partners of the mines.

We produce various grades of iron ore pellets, including standard and fluxed, for use in our customers’ blast 
furnaces as part of the steelmaking process.  Additionally, as the EAF steel market continues to grow in the U.S., there 
is an opportunity for our iron ore to serve this market by providing pellets to the alternative metallics market to produce 
direct reduced iron pellets, hot briquetted iron and/or pig iron.  In 2015, we produced and shipped a batch trial of DR-
grade pellets, a source of lower silica iron units for the production of direct reduced iron pellets.  In early 2016, we reached 
a significant milestone with positive results from the successful industrial trial of our DR-grade pellets.  While we are still 
in the early stages of developing our alternative metallic business, we believe this will open up a new opportunity for us 
to diversify our product mix and add new customers to our U.S. Iron Ore segment beyond the traditional blast furnace 
clientele.

The variation in grades of iron ore pellets results from the specific chemical and metallurgical properties of the 
ores at each mine and whether or not fluxstone is added in the process.  Although the grade or grades of pellets currently 
delivered to each customer are based on that customer’s preferences, which depend in part on the characteristics of the 
customer’s blast furnace operation, in many cases our iron ore pellets can be used interchangeably.  Industry demand 
for the various grades of iron ore pellets depends on each customer’s preferences and changes from time to time.  In 
the event that a given mine is operating at full capacity, the terms of most of our pellet supply agreements allow some 
flexibility in providing our customers iron ore pellets from different mines.

Standard pellets require less processing, are generally the least costly pellets to produce and are called “standard” 
because no ground fluxstone, such as limestone or dolomite, is added to the iron ore concentrate before turning the 
concentrate into pellets.  In the case of fluxed pellets, fluxstone is added to the concentrate, which produces pellets that 
can perform at higher productivity levels in the customer’s specific blast furnace and will minimize the amount of fluxstone 
the customer may be required to add to the blast furnace.

Each  of  our  U.S.  Iron  Ore  mines  is  located  near  the  Great  Lakes.   The  majority  of  our  iron  ore  pellets  are 

transported via railroads to loading ports for shipment via vessel to steelmakers in North America.

Our U.S. Iron Ore sales are influenced by seasonal factors in the first quarter of the year as shipments and sales 
are restricted by the Army Corp of Engineers due to closure of the Soo Locks and the Welland Canal on the Great Lakes.  
During the first quarter, we continue to produce our products, but we cannot ship those products via lake vessel until the 
conditions on the Great Lakes are navigable, which causes our first and second quarter inventory levels to rise.  Our 
limited practice of shipping product to ports on the lower Great Lakes or to customers’ facilities prior to the transfer of 
title has somewhat mitigated the seasonal effect on first and second quarter inventories and sales, as shipment from 
this point to the customers’ operations is not limited by weather-related shipping constraints.  At December 31, 2015 and 
2014, we had approximately 1.3 million and 1.4 million tons of pellets, respectively, in inventory at lower lakes or customers’ 
facilities.

U.S. Iron Ore Customers

Our U.S. Iron Ore revenues primarily are derived from sales of iron ore pellets to the North American integrated 
steel industry, consisting of three major customers, two of which we currently have supply agreements.  During the fourth 
quarter of 2015, we terminated the long term agreement with our third major customer as a result of the continual material 
breaches.  Refer to the Essar section within Concentration of Customers below for further information.  Generally, we 
have multi-year supply agreements with our customers.  Sales volume under these agreements largely is dependent on 
customer requirements, and in many cases, we are the sole supplier of iron ore to the customer.  Historically, each 
agreement has contained a base price that is adjusted annually using one or more adjustment factors.  Factors that 
could result in a price adjustment include spot pricing, measures of general industrial inflation and steel prices.  Additionally, 
certain of our supply agreements have a provision that limits the amount of price increase or decrease in any given year.

During 2015, 2014 and 2013, we sold 17.3 million, 21.8 million and 21.3 million tons of iron ore pellets, respectively, 
from our share of the production from our U.S. Iron Ore mines.  The segment’s three major customers together accounted 
for a total of 93 percent, 86 percent and 78 percent of U.S. Iron Ore product revenues for the years 2015, 2014 and 
2013, respectively.  Refer to Concentration of Customers below for additional information regarding our major customers.

Asia Pacific Iron Ore

Our Asia Pacific Iron Ore operations are located in Western Australia and consist solely of our wholly owned 

Koolyanobbing operation.

The Koolyanobbing operations serve the Asian iron ore markets with direct-shipped fines and lump ore.  The 
lump products are fed directly to blast furnaces, while the fines products are used as sinter feed.  The variation in the 
two export product grades reflects the inherent chemical and physical characteristics of the ore bodies mined as well as 

6

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

the supply requirements of our customers. Production in 2015 was 11.7 million metric tons, compared with 11.4 million 
metric tons in 2014 and 11.1 million metric tons in 2013.

Koolyanobbing is a collective term for the deposits at Koolyanobbing, Mount Jackson and Windarling.  There 
are approximately 70 miles separating the three mining areas.  The operations at Windarling have been idled since the 
beginning of the fourth quarter of 2015 as a result of cost cutting measures.  Banded iron formations host the mineralization, 
which is predominately hematite and goethite.  Each deposit is characterized with different chemical and physical attributes 
and, in order to achieve customer product quality, ore in varying quantities from each deposit must be blended together. 

Crushing and blending are undertaken at Koolyanobbing, where the crushing and screening plant is located.  
Once the blended ore has been crushed and screened into a direct lump and fines shipping product, it is transported by 
rail approximately 360 miles south to the Port of Esperance, via Kalgoorlie, for shipment to our customers in Asia.

Asia Pacific Iron Ore Customers

Asia Pacific Iron Ore’s production is under contract with steel companies primarily in China, Japan and Korea.  
In March 2015, we extended the majority of our supply agreements with steel producers in China, and one steel producer 
in Japan, for two years.  The remaining supply agreements with our China steel clients, as well as clients in Japan and 
Korea, will currently expire in March 2016, but we anticipate that the majority of these contracts will be renewed for the 
remainder of 2016 in conjunction with our customers’ fiscal year.  Pricing for our Asia Pacific Iron Ore Chinese customers 
consists of shorter-term pricing mechanisms of various durations up to 45 days based on the average of daily spot prices 
that  are  generally  associated  with  the  time  of  unloading  of  each  shipment.   Pricing  with  our  Japanese  and  Korean 
customers is generally consistent with the inputs used with our Chinese customers, but the pricing inputs are fixed before 
shipment.  

During 2015, 2014 and 2013, we sold 11.6 million, 11.5 million and 11.0 million metric tons of iron ore, respectively, 
from our Western Australia mines.  No Asia Pacific Iron Ore customer comprised more than 10 percent of Cliffs consolidated 
sales in 2015, 2014 or 2013.  The segment’s five largest customers together accounted for a total of 47 percent, 38 
percent and 42 percent of Asia Pacific Iron Ore product revenues for the years 2015, 2014 and 2013, respectively.

North American Coal

Throughout the majority of 2015, we owned and operated two low-volatile metallurgical coal operations located 
in Alabama and West Virginia. These low-volatile metallurgical coal operations had a rated capacity of 6.5 million tons 
of production annually.  In the fourth quarter of 2015, we sold these two low-volatile metallurgical coal operations, Pinnacle 
mine and Oak grove mine, marking our exit from the coal business. The sale was completed on December 22, 2015.  In 
2015, we sold a total of 4.6 million tons, compared with 7.4 million tons in 2014 and 7.3 million tons in 2013.  In the fourth 
quarter of 2014, we sold our CLCC assets, which consisted of two high-volatile metallurgical coal mines and a thermal 
coal mine. The sale was completed on December 31, 2014.  Sales tons at the CLCC operations were 2.4 million tons 
and 2.2 million tons for the years ended December 31, 2014 and 2013, respectively, and are included in the sales tons 
disclosed above.  

As of March 31, 2015, management determined that our North American Coal operating segment met the criteria 
to be classified as held for sale under ASC 205, Presentation of Financial Statements.  As such, all current year and 
historical North American Coal operating segment results are included in our financial statements and classified within 
discontinued operations.  Refer to NOTE 14 - DISCONTINUED OPERATIONS for further discussion of the North American 
Coal segment discontinued operations.

Eastern Canadian Iron Ore 

We continue to own two iron ore mines in Eastern Canada that are currently in restructuring proceedings in 

Montreal, Quebec, under the CCAA. 

As  disclosed  in  the  first  quarter  of  2014,  at  the  end  of  March  2014,  we  idled  our  Wabush  Scully  mine  in 
Newfoundland and Labrador and in November 2014, we began to implement the permanent closure plan for the mine.  
The idle and ultimate closure was driven by the unsustainable high cost structure.  Additionally, we disclosed in November 
2014, that we were pursuing exit options for our Bloom Lake mine.  As disclosed in January 2015, active production at 
the Bloom Lake mine had ceased and the mine had transitioned to "care-and-maintenance" mode.  Together, the shutdown 
of the Wabush Scully mine and the cessation of operations at our Bloom Lake mine represented a complete curtailment 
of our Eastern Canadian Iron Ore operations.

During  2014  and  2013,  we  sold  7.2  million  and  8.6  million  metric  tons  of  iron  ore  concentrate  and  pellets, 

respectively, from our Eastern Canadian Iron Ore mines.  

7

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

As more fully described in NOTE 14 - DISCONTINUED OPERATIONS, in January 2015, we announced that 
the Bloom Lake Group commenced restructuring proceedings in Montreal, Quebec under the CCAA.  At that time, we 
had recently suspended Bloom Lake operations and for several months had been exploring options to sell certain of our 
Canadian assets, among other initiatives.  Effective January 27, 2015, following the CCAA filing of the Bloom Lake Group, 
we deconsolidated the Bloom Lake Group and certain other wholly-owned subsidiaries comprising substantially all of 
our Canadian operations.  Additionally, on May 20, 2015, the Wabush Group commenced restructuring proceedings in 
Montreal, Quebec under the CCAA which resulted in the deconsolidation of the remaining Wabush Group entities that 
were not previously deconsolidated.  The Wabush Group was no longer generating revenues and was not able to meet 
its obligations as they came due.  As a result of this action, the CCAA protections granted to the Bloom Lake Group were 
extended to include the Wabush Group to facilitate the reorganization of each of their businesses and operations.  Financial 
results prior to the respective deconsolidations of the Bloom Lake and Wabush Groups and subsequent expenses directly 
associated  with  the  Canadian  Entities  are  included  in  our  financial  statements  and  classified  within  discontinued 
operations. 

Refer to NOTE 14 - DISCONTINUED OPERATIONS for further discussion of the Eastern Canadian Iron Ore 

segment discontinued operations.

Investments

Amapá 

On December 27, 2012, our Board of Directors authorized the sale of our 30 percent interest in Amapá.  Per this 
original agreement, together with Anglo, we were to sell our respective interest in a 100 percent sale transaction to Zamin.

On March 28, 2013, an unknown event caused the Santana port shiploader to collapse into the Amazon River, 
preventing further ship loading by the mine operator, Anglo.  In light of the Santana port shiploader collapse and subsequent 
evaluation of the effect that this event had on the carrying value of our investment in Amapá as of June 30, 2013, we 
recorded an impairment charge of $67.6 million in the second quarter of 2013.

On August 28, 2013, we entered into additional agreements to sell our 30 percent interest in Amapá to Anglo for 
nominal cash consideration, plus the right to certain contingent deferred consideration upon the two-year anniversary of 
the closing.  However, no contingent deferred consideration was earned upon the two-year anniversary.  The closing 
was conditional on obtaining certain regulatory approvals and the additional agreement provided Anglo with an option 
to request that we transfer our interest in Amapá directly to Zamin.  Anglo exercised this option and the transfer to Zamin 
closed in the fourth quarter of 2013.  Our interest in Amapá previously was reported as our Latin American iron ore 
operating segment.

Applied Technology, Research and Development

We have been a leader in iron ore mining and process technology for more than 160 years.  We operated some 
of the first mines on Michigan’s Marquette Iron Range and pioneered early open-pit and underground mining methods.  
From the first application of electrical power in Michigan’s underground mines to the use of today’s sophisticated computers 
and global positioning satellite systems, we have been a leader in the application of new technology to the centuries-old 
business of mineral extraction.  Today, our engineering and technical staffs are engaged in full-time technical support of 
our operations and improvement of existing products.

We are a pioneer in iron ore pelletizing with over 60 years of experience.  We are able to produce customized 
pellets to meet each customer’s blast furnace specifications, and produce both standard and fluxed pellets. Using our 
technical expertise and strong market position in the United States to increase our product offering, we have been 
working on producing DR-grade pellets.  In 2015, we produced and shipped a batch trial of DR-grade pellets, a source 
of lower silica iron units for the production of direct reduced iron pellets.  In early 2016, we reached a significant 
milestone with positive results from the successful industrial trial of our DR-grade pellets.

With state-of-the-art equipment and experienced technical professionals, we remain on the forefront of mining 
technology.  We have an unsurpassed reputation for our pelletizing technology, delivering a world-class quality product

Concentration of Customers

In 2015, 2014 and 2013 we had three customers that individually accounted for more than 10 percent of our 
consolidated  product  revenue.  Product  revenue  from  those  customers  represented  in  the  chart  below  totaled 
approximately $1.3 billion, $1.9 billion and $1.9 billion of our total consolidated product revenue in 2015, 2014 and 2013, 
respectively, and is attributable to our U.S. Iron Ore business segment.  The following represents sales revenue from 
each of these customers as a percentage of our total consolidated product revenue, as well as the portion of product

Table of Contents

AK Steel

On September 16, 2014, AK Steel announced an acquisition of Severstal North America’s integrated steelmaking 
assets located in Dearborn, Michigan.  We had a long-term relationship to supply iron ore pellets to Severstal’s steelmaking 
assets at that location.  Upon consummation of the acquisition, the contract was automatically assigned to AK Steel.  
The combination of sales pursuant to our preexisting sales agreement with AK Steel and the acquisition of the Dearborn 
facility with its sales agreement accounts for more than 10 percent of our consolidated product revenue in 2015, 2014 
and 2013.   

On August 29, 2013 we entered into a new agreement with AK Steel to provide iron ore pellets to AK Steel for 
use in its Middletown, Ohio and Ashland, Kentucky blast furnace facilities.  This contract includes minimum and maximum 
tonnage requirements for each year between 2014 and 2023.  

Under the original agreement entered into with Severstal in 2006, we supply all of the Dearborn, Michigan facility’s 
blast furnace pellet requirements through 2022, subject to specified minimum and maximum requirements in certain 
years. AK Steel was the successor by merger of this contract and it remains in force.  In September 2014, we entered 
into an amendment to the Dearborn contract with AK Steel to document the 2013 base pricing provisions, among other 
things, which resulted from an arbitration ruling in May 2014. 

In 2015, 2014 and 2013, our U.S. Iron Ore pellet sales to AK Steel and the acquired Dearborn facility were 4.3 

million, 5.8 million and 4.1 million tons, respectively. 

Essar

Essar Steel Algoma Inc. ("Essar") is a Canadian steelmaker and a subsidiary of Essar Steel Holdings Limited.  
We had a long term supply agreement under which we were Essar’s sole supplier of iron ore pellets through the end of 
2016 and were required to deliver a set tonnage for less than Essar’s entire requirements through 2024. There were 
multiple contract disputes that led to us filing a complaint in the Federal District Court in the Northern District of Ohio on 
January 12, 2015.  During the litigation process we asserted additional claims of material breach as a result of Essar’s 
actions during the 2015 calendar year.  

On October 5, 2015, Cliffs terminated the long term agreement with Essar as a result of Essar's multiple and 
material breaches and ceased to supply Essar with pellets.  On November 9, 2015, Essar filed for CCAA and Chapter 
15 bankruptcy protection.  We do not currently supply pellets to Essar and whether we will be required to supply pellets 
in the future is undetermined at this time. The Canadian Superior Court may require Cliffs to supply Essar under the 
terms of the agreement or other terms.  Essar moved the Canadian CCAA Court to enter an injunction requiring us to 
supply pellets.  We filed a motion to remove the case to Ohio due to the CCAA Court's lack of jurisdiction.  On January 
25, 2016, the CCAA Court determined that it has jurisdiction over the issue.  We remain open to discussing supplying 
pellets on  commercially reasonable  terms consistent  with a just-in-time  iron  ore  supply  arrangement.  Our  obligation 
during 2015 was also undetermined and was a claim that was to be determined in the U.S. litigation.  We delivered 
approximately  2.5  million  tons  in  2015  prior  to  termination  for  which  we  received  payment,  but  of  that  amount, 
approximately 860 thousand tons were carryover tons.  Pricing under the terminated agreement had been based on a 
formula that includes international pellet prices. 

In 2015, 2014 and 2013, our U.S. Iron Ore pellet sales to Essar were 2.5 million, 3.5 million and 3.4 million tons, 

respectively.

Competition

Throughout the world, we compete with major and junior mining companies, as well as metals companies, both 

of which produce steelmaking raw materials, including iron ore.

North America

In our U.S. Iron Ore business segment, we primarily sell our product to steel producers with operations in North 
America. We compete directly with steel companies that own interests in iron ore mines in the United States and/or 
Canada, including ArcelorMittal and U.S. Steel, and with major iron ore pellet exporters from Eastern Canada and Brazil.  
Additionally, in 2015, finished steel import market share was a record 29 percent in the U.S., up from 28 percent in 2014.  
As a result, steel utilization rates in North America were recorded at multi-year lows. The reduced demand for U.S. 
produced steel negatively affects the demand for iron ore pellets within North America.

10

 
 
 
 
 
 
 
 
  
 
 
 
Table of Contents

A number of factors beyond our control affect the markets in which we sell our iron ore.  Continued demand for 
our iron ore and the prices obtained by us primarily depend on the consumption patterns of the steel industry in the U.S., 
China and elsewhere around the world, as well as the availability, location, cost of transportation and competing prices. 

Asia Pacific

In our Asia Pacific Iron Ore business segment, we export iron ore products to the Asia Pacific markets, including 
China,  Japan,  Korea  and Taiwan.    In  the Asia  Pacific  marketplace,  we  compete  with  major  iron  ore  exporters  from 
Australia, Brazil and South Africa.  These include Anglo, BHP Billiton, Fortescue Metals Group Ltd., Rio Tinto plc and 
Vale, among others.

Competition in steelmaking raw materials is predicated upon the usual competitive factors of price, availability 

of supply, product quality and performance, service and transportation cost to the consumer of the raw materials.  

Environment 

Our mining activities are subject to various laws and regulations governing the protection of the environment.  
We conduct our operations in a manner that is protective of public health and the environment and believe our operations 
are in compliance with applicable laws and regulations in all material respects.

Environmental  issues  and  their  management  continued  to  be  an  important  focus  at  each  of  our  operations 
throughout 2015.  In the construction of our facilities and in their operation, substantial costs have been incurred and will 
continue to be incurred to avoid undue effect on the environment.  Our capital expenditures relating to environmental 
matters totaled approximately $17 million, $33 million and $32 million, in 2015, 2014 and 2013, respectively.  Approximately 
$5 million, $3 million and $5 million of the 2015, 2014 and 2013 capital expenditures, respectively,  relating to environmental 
matters  is  attributable  to  the  North American  Coal  operations  that  were  sold  during  December  2015.   Additionally, 
approximately  $22  million  and  $14  million  of  the  2014  and  2013  capital  expenditures,  respectively,  relating  to 
environmental matters, but excluding any expenditures relating to the Bloom Lake tailings and water management system, 
is attributable to the Eastern Canadian Iron Ore operations that are currently in restructuring proceedings under the 
CCAA. It is estimated that capital expenditures for environmental improvements will total approximately $26 million in 
2016 which is related to our U.S. Iron Ore operations for various water treatment, air quality, dust control, selenium 
management, tailings management and other miscellaneous environmental projects.

Regulatory Developments

Various  governmental  bodies  continually  promulgate  new  or  amended  laws  and  regulations  that  affect  our 
Company, our customers and our suppliers in many areas, including waste discharge and disposal, the classification of 
materials and products, air and water discharges and many other environmental, health and safety matters.  Although 
we believe that our environmental policies and practices are sound and do not expect that the application of any current 
laws or regulations reasonably would be expected to result in a material adverse effect on our business or financial 
condition, we cannot predict the collective adverse impact of the expanding body of laws and regulations.

Specifically, there are several notable proposed or potential rulemakings or activities that could potentially have 
a material adverse impact on our facilities in the future depending on their ultimate outcome: Climate Change and GHG 
Regulation,  Regional  Haze,  NO2  and  SO2  National Ambient Air  Quality  Standards,  Cross  State Air  Pollution  Rule, 
increased administrative and legislative initiatives related to mining activities, Mercury TMDL and Minnesota Taconite 
Mercury Reduction Strategy's evolving water quality standards for selenium, sulfate and conductivity and scope of the 
Clean Water Act and definition of “Waters of the United States”.

Climate Change and GHG Regulation

With the complexities and uncertainties associated with the U.S. and global navigation of the climate change 
issue as a whole, one of our significant risks for the future is mandatory carbon legislation.  Policymakers are in the 
design  process  of  carbon  regulation  at  the  state,  regional,  national  and  international  levels.   The  current  regulatory 
patchwork of carbon compliance schemes presents a challenge for multi-facility entities to identify their near-term risks.  
Amplifying the uncertainty, the dynamic forward outlook for carbon regulation presents a challenge to large industrial 
companies to assess the long-term net impacts of carbon compliance costs on their operations.  Our exposure on this 
issue includes both the direct and indirect financial risks associated with the regulation of GHG emissions, as well as 
potential physical risks associated with climate change.  We are continuing to review the physical risks related to climate 
change utilizing a formal risk management process.  As an energy-intensive business, our GHG emissions inventory 
captures a broad range of emissions sources, such as iron ore furnaces and kilns,  diesel mining equipment and our 
wholly owned Silver Bay power generation plant, among others.  As such, our most significant regulatory risks are: (1) the 
costs  associated  with  on-site  emissions  levels  (direct  impacts),  and  (2) the  costs  passed  through  to  us  from  power 
generators and distillate fuel suppliers (indirect impacts).

Internationally,  mechanisms  to  reduce  emissions  are  being  implemented  in  various  countries,  with  differing 
designs and stringency, according to resources, economic structure and politics.  We expect that momentum to extend 
carbon regulation will continue with passage of the "Paris Climate Agreement" to keep global temperature rise to below 
two degrees Celsius.  Continued political attention to issues concerning climate change, the role of human activity in it 
and potential mitigation through regulation may have a material impact on the company's customer base, operations 
and financial results in the future.

In the U.S., federal carbon regulation potentially presents a significantly greater impact to our operations.  To 
date, the U.S. Congress has not legislated carbon constraints.  In the absence of comprehensive federal carbon legislation, 
numerous state, regional, and federal regulatory initiatives are under development or are becoming effective, thereby 
creating a disjointed approach to carbon control.  On May 13, 2010, the U.S. EPA promulgated the GHG Tailoring Rule 
establishing a mechanism for regulating GHG emissions from facilities through the Prevention of Significant Deterioration  
permitting program under the CAA. Under the GHG Tailoring Rule, as modified by the recent U.S. Supreme Court decision 
upholding some components of the rule, new projects that increase GHG emissions by a significant amount (generally 
more than 75,000 tons of CO2 emissions per year) are subject to the PSD requirements, including the installation of best 
available  control  technology,  if  the  project  also  significantly  increases  emissions  of  at  least  one  non-GHG  regulated 
criteria pollutant. We do not expect the Tailoring Rule provision to materially adversely affect our business in the near 
term and we cannot reliably estimate the long term impact of the regulation. 

On June 25, 2013, President Obama issued a memorandum directing the EPA to develop carbon emission 

standards for both new and existing power plants under the Clean Air Act's NSPS.  On October 23, 2015, EPA 
promulgated the "Clean Power Plan" which consists of NSPS regulating carbon dioxide from existing power plants at 
a level of approximately 32 percent below 2005 levels by 2030.  States must submit Clean Power Plan SIPs by 
September 2016, though extension waivers until 2018 are available. These rules do not affect our Silver Bay 
combined heat and power generating facility. We anticipate that EPA will continue to work on additional GHG NSPS 
regulations for other industrial categories, including the iron and steel industry, however we cannot reliably estimate 
the timing or long term impact of future NSPS regulations. 

Due  to  the  EPA's Tailoring  Rule  and  GHG  NSPS  regulations  our  business  and  customer  base  could  suffer 
negative financial impacts over time as a result of increased energy, environmental and other costs in order to comply 
with the limitations that would be imposed on greenhouse gas emissions. We believe our exposure can be reduced 
substantially by numerous factors, including currently contemplated regulatory flexibility mechanisms, such as allowance 
allocations, fixed process emissions exemptions, offsets and international provisions; emissions reduction opportunities, 
including energy efficiency, biofuels, fuel flexibility, emerging shale gas, coal mine methane offset reduction; and business 
opportunities associated with pursuing combined heat and power partnerships and new products, including DRI pellets, 
fluxed pellets and other technology.

We have worked proactively to develop a comprehensive, enterprise-wide GHG management strategy aimed 
at considering all significant aspects associated with GHG initiatives to plan effectively for and manage climate change 
issues, including risks and opportunities as they relate to the environment, stakeholders, including shareholders and the 
public, legislative and regulatory developments, operations, products and markets.

Regional Haze

In June 2005, the EPA finalized amendments to its regional haze rules.  The rules require states establish goals 
and emission reduction strategies for improving visibility in all Class I national parks and wilderness areas.  Among the 
states with Class I areas are Michigan and Minnesota in which we currently own and manage mining operations.  The 
first phase of the regional haze rule (2008-2018) requires analysis and installation of BART on eligible emission sources 
and incorporation of BART and associated emission limits into SIPs.

Minnesota submitted a regional haze SIP to the EPA on December 30, 2009, and a supplement to the SIP on 
May 8, 2012.  Michigan submitted its regional haze SIP to the EPA on November 5, 2010.  During the second quarter of 
2012, the EPA also sent information requests to all taconite facilities requesting information on SO2 and NOx emissions 
and control technology assessments.  On June 12, 2012, the EPA approved revisions to the Minnesota SIP addressing 
regional haze, but also announced it was deferring action on emission limitations that Minnesota intended to represent 
BART for taconite facilities.  On August 15, 2012, the EPA proposed to deny the Michigan and Minnesota taconite SIP 
BART determinations and simultaneously proposed a separate FIP for taconite facilities.  During the comment period 
for  the  proposed  FIP  rule,  the  taconite  industry  and  other  stakeholders  developed  detailed  comments  and  shared 
information to address furnace specific case-by-case circumstances.  On January 15, 2013, the EPA signed the final FIP 
for taconite facilities.  The final FIP reflects progress toward a more technically and economically feasible regional haze 
implementation plan and eliminates the need for investing in additional SO2 emission control equipment. However, we 
remain concerned about the technical and economic feasibility of EPA's BART determination for NOx emissions and we 
filed a petition for review in the 8th Circuit Court and subsequently received a judicial stay of the FIP which enabled us 
to conduct a detailed engineering analysis to determine the impact of the regulations on each unique iron ore indurating 
furnace affected by this rule.  The results of this analysis enabled us to reach a settlement with EPA which was incorporated 
into an amended rule and public noticed in the Federal Register on October 22, 2015.  Cost estimates associated with 
the settlement are reflected in our 5-year capital plan.

NO2 and SO2 National Ambient Air Quality Standards

During the first half of 2010, the EPA promulgated rules that require states to use a combination of air quality 
monitoring  and  computer  modeling  to  determine  areas  of  each  state  that  are  in  attainment  with  new  NO2  and  SO2 
standards and those areas that are not in attainment with such standards.  During the third quarter of 2011, the EPA 
issued guidance to the regulated community on conducting refined air quality dispersion modeling and implementing the 
new NO2 and SO2 standards.  During June 2011, our Minnesota iron ore mining operations received a request from the 
MPCA to develop modeling and compliance plans by which each facility would demonstrate compliance with the NO2 
and SO2 NAAQS pursuant to the Taconite Regional Haze SIP Long Term Strategy (LTS).  Compliance with the LTS 
modeling  demonstrations  was  originally  set  for  June  30,  2017.    On August  20,  2015,  EPA  released  its  final  Data 
Requirement Rule (DRR) for characterizing SO2 sources under the 2010 1 Hr SO2 NAAQS.  Cliffs’ operation subject to 
the SO2 DRR, Northshore Mining, is anticipated to demonstrate compliance with the SO2 DRR without incurring additional 
capital investment.  All of our other operations in Minnesota and Michigan are expected to be in attainment for NO2 and 
SO2 NAAQS without incurring additional capital investment.  Further, Minnesota is expected to remove NAAQS modeling 
obligations under the LTS in light of reduction in haze emissions associated with pending amendment of the taconite 
Regional Haze FIP regulations.  While we will continue to monitor these developments and assess potential impacts to 
Cliffs, we do not anticipate further capital investments will be necessary for the pending NO2 and SO2 DRR SIP rulemaking. 

Cross State Air Pollution Rule

On July 6, 2011, the EPA promulgated the CSAPR, which was intended to be an emissions trading rule for SO2 
and NOx.  Northshore's Silver Bay Power Plant would have been subject to this rule; however Minnesota elected to 
follow EPA guidance allowing CSAPR to stand as BART.  CSAPR was vacated by the D.C. Circuit Court during the third 
quarter of 2012.  Late in 2014, the Supreme Court re-instated CSAPR with an effective date of January 1, 2015, re-
instating the obligations of this rule for Silver Bay Power.  In January, 2016, the 8th Circuit Court of Appeals re-affirmed 
EPA use of CSAPR is equal to or better than BART. Immediate compliance obligations are being met at this time, with 
the material obligation being procurement of the first year of emissions allowances by March 2016 for the 2015 operating 
year.  Silver Bay Power has installed low NOx burners to reduce emissions that will limit the cost exposure to the emission 
trading market.  The allowance pricing market indicates the annual costs to comply with CSAPR will be less than $0.2 
million for 2015 and future allowance prices are anticipated to remain favorable under the existing framework.   While 
we  will  continue  to  monitor  the  availability  and  pricing  of  CSAPR  allowances  and  future  EPA  allocations  of  CSAPR 
allowances to Northshore’s Silver Bay Power Plant, we do not anticipate exposure to material costs for existing CSAPR 
obligations and we cannot reasonably estimate the long term impact of CSAPR should EPA reduce the allocations in 
response to future lower ozone or PM2.5 regulations.

Mercury TMDL and Minnesota Taconite Mercury Reduction Strategy

TMDL regulations are contained in the Clean Water Act.  As a part of Minnesota's Mercury TMDL Implementation 
Plan, in cooperation with the MPCA, the taconite industry developed a Taconite Mercury Reduction Strategy and signed 
a voluntary agreement in 2009 to effectuate its terms.  The strategy includes a 75 percent target reduction of mercury 
air emissions from Minnesota pellet plants collectively by 2025.  It recognizes that mercury emission control technology 
currently  does  not  exist  and  will  be  pursued  through  a  research  effort.  According  to  the  voluntary  agreement,  any 
developed technology must meet the “adaptive management criteria” such that the technology must be economically 
feasible, must not impact pellet quality, and must not cause excessive corrosion in pellet furnaces, associated duct work 
and existing wet scrubbers on the furnaces.

According to the voluntary agreement, the mines proceeded with medium- and long-term testing of possible 
technologies.  For Cliffs, the requirements in the voluntary agreement apply to the United Taconite and Hibbing facilities.  
At this time, we are unable to predict the potential impacts of the voluntary Taconite Mercury Reduction Strategy.  However, 
a number of research projects were conducted between 2011 and 2014 as the industry continues to assess options for 
reduction.  While injection of powdered activated carbon into furnace off-gasses for mercury capture in the wet scrubbers 
showed  positive  initial  results,  further  testing  during  2013  yielded  lower  overall  potential. Alternate  technologies  are 
presently being assessed in our ongoing efforts to develop cost effective mercury reduction technologies for our indurating 
furnaces.

On  September  22,  2014,  Minnesota  promulgated  the  Mercury Air  Emissions  Reporting  and  Reduction  Rule 
mandating mercury air emissions reporting and reduction. The adopted rule expanded applicability to all of our Minnesota 
operations and requires submitting a mercury reduction plan in 2018 to reduce mercury emissions from all of our Minnesota 
taconite furnaces by 72 percent by January 2025. The adopted rule does not include all four Adaptive Management 
Criteria for evaluating mercury reduction, which were agreed upon in the October 2009 Minnesota’s Mercury TMDL 
Implementation Plan. 

To  date,  there  is  currently  no  proven  technology  to  cost  effectively  reduce  mercury  emissions  from  taconite 
furnaces to the target level of 72 percent that would meet all four Adaptive Management Criteria. We remain concerned 
about the technical and economic feasibility to reduce taconite mercury emissions by 72 percent and are conducting 
detailed engineering analysis to determine the impact of the regulations on each unique iron ore indurating furnace 
affected by this rule.  The results of this analysis will guide further dialog with the MPCA regarding our implementation 
of the requirements.  Because development of the technology is in the early stages, any impacts to Cliffs are not estimable 
at this time.

Selenium Discharge Regulation

In Michigan, Empire and Tilden have developed compliance strategies to manage selenium according to the 
permit conditions.  Empire and Tilden submitted the first permit required Selenium Storm Water Management Plan to 
the MDEQ in December 2011; and have updated it annually as required.  The Selenium Storm Water Management Plan 
outlines the activities that will be undertaken to address selenium in storm water discharges from our Michigan operations.    
A prefeasibility engineering estimate for full scale implementation of the storm water collection and conveyance system 
by November 2017 is approximately $24 million and is included in the 5-year capital plan.  A storm water treatment 
system  for  both  facilities  is  anticipated  sometime  before  2025.    The  cost  of  the  future  treatment  systems  could  be 
significant, although we are continuing to assess and develop cost effective and sustainable treatment technologies. 

Tilden's NPDES permit contains a compliance schedule for selenium with a limit of five µg/l that will be effective 
as of November 1, 2017, at Tilden's Gribben Tailings Basin outfall.  Tilden initiated a prudent and feasible alternatives 
analysis to further define solutions and cost estimates. An engineering estimate for the selected suite of solutions indicates 
capital costs will be less than $23 million.  In July 2015, the EPA proposed new selenium fish tissue limits and lower 
lentic and lotic water column concentration criteria which may increase the cost for treatment. We are incorporating this 
contingency into our planning and treatment technology assessment.

Definition of “Waters of the United States” Under the Clean Water Act

The EPA and Army Corps of Engineers’ promulgated the rule, “Definition of ‘Waters of the United States’ Under 
the Clean Water Act,”  80 Fed. Reg. 37053 (June 29, 2015), which attempted to add clarity to which waters are jurisdictional 
under the federal Clean Water Act, and will apply to all Clean Water Act programs, including the Sec. 402 and Sec. 404 
permitting programs, Sec. 311 spill prevention program and Sec. 401 state certification process.  It is unclear how the 
federal and state agencies will implement and enforce the final rule, and how the courts will interpret going forward.  The 
regulation may expand EPA’s authority under the Clean Water Act to many traditionally unregulated mine features such 
as mine pits, pit lakes, on site ditches, water retention structures, and tailings basins creating a new burden on our U.S. 
facilities.  This could further be interpreted to add questionable regulatory authority over the groundwater connections 
between these features and nearby traditionally navigable waters.  On October 9, 2015, the U.S. Court of Appeals for 
the Sixth Circuit issued a nationwide stay of this rule while the jurisdiction and legality of the rule are decided in court.  
We  are  actively  participating  in  the  rulemaking  development  and  assessing  the  potential  impacts  to  our  operations. 
Because the rule is being litigated, and until the rule is finally implemented, any impacts to Cliffs are not estimable at this 
time.

Minnesota’s Proposed Sulfate Wild Rice Water Quality Standard

The Minnesota Legislature provided $1.5 million in 2011 for a study to gather additional information about the 
effects of sulfate and other substances on the growth of wild rice, and to support an update to the sulfate wild rice water 
quality standard originally adopted in 1973 by the MPCA. The MPCA contracted with the University of Minnesota to 
conduct several research projects as part of this study.  Concurrently, the Minnesota Chamber of Commerce contracted 
an independent lab to conduct companion research on the impacts of sulfate on wild rice. In March 2015, MPCA released 
a draft proposal for protecting wild rice from sulfate, which included a draft sulfate wild rice water quality standard, a draft 
list of waters where the standard would apply, and criteria for adding waters to that list.  The draft wild rice water quality 
standard is an equation that utilizes measured sediment parameters to calculate a sulfate limit protective of wild rice.  
The independent research conducted by the independent lab contracted by the Minnesota Chamber of Commerce does 
not directly support the validity of the MPCA’s proposed approach.  The rulemaking has a legislated deadline for completion 
of January 15, 2018.  Due to the proposed standard being based on measured sediment parameters that Cliffs is not in 
possession of near our operating facilities, and uncertainty regarding which waters the standard will apply to, the impacts 
of the proposed wild rice water quality standard to Cliffs are not estimable at this time.

Conductivity

Conductivity, the measurement of water’s ability to conduct electricity, is a surrogate parameter that generally 
increases as the amount of dissolved minerals in water increases.  In 2011, the EPA issued “A Field-Based Aquatic Life 
Benchmark for Conductivity in Central Appalachian Streams” which established a recommended conductivity benchmark 
of 300 µS/cm for the region.  The issuance of a benchmark outside of the established rulemaking process was subsequently 
the subject of litigation in National Mining Association v. Jackson, 880 F. Supp. 2d 119 (D.D.C. 2012) where the court 
ruled the benchmark is nothing more than a non-binding suggestion.  Three years later in Ohio Valley Environmental 
Coalition, et al. v. Elk Run Coal Co., et al., 3:12-cv-00785 (S.D. W. Va.), a judicial decision held that levels of conductivity 
higher than the EPA’s benchmark constituted a violation of the state’s narrative water quality standards, were unsupported 
by science and contrary to decisions previously made by the West Virginia DEP and the West Virginia Supreme Court.  
In 2015, a group filed a petition with EPA Region 5 alleging that Minnesota was failing to properly implement the state 
NPDES program; and one of the various allegations asserts that MPCA should be assessing compliance with the state’s 
narrative  water  quality  standard  against  the  EPA’s  conductivity  benchmark  for  the  Central Appalachian  region.    On 
December 30, 2015, the EPA provided MPCA a draft of the Protocol for Responding to Issues Related to Permitting and 
Enforcement which indicates that EPA staff will be reviewing available scientific basis in peer reviewed literature as well 
as promulgated standards.  Since the EPA’s review has yet to begin and the forthcoming findings and recommendations, 
if  any,  are  unknown,  the  exact  nature  of  the  risk  to  Cliffs  is  unknown;  however,  direct  application  of  the  300  µS/cm 
benchmark to Cliffs’ Minnesota-based assets may have a material impact.

Energy

Electricity

The state of Michigan is a deregulated electricity state, which affords our mines the ability to purchase electrical 
energy supply from various suppliers while continuing to purchase distribution service from the incumbent utility.  As of 
September 1, 2013, our Tilden and Empire mines in Michigan exercised the right to purchase electrical supply from 
Integrys Energy Services while continuing to purchase distribution service from Wisconsin Electric Power Company.  The 
pricing of electricity in the deregulated market is based on the Midwestern Independent System Operator Day-Ahead 
price.  Beginning on February 1, 2015, we began purchasing our electricity supply from the Wisconsin Electric Power 
Company in a regulated fashion as we terminated our contract with Integrys Energy Services.  As of February 1, 2015, 
Wisconsin Electric Power Company is the sole supplier of electric power to our Empire and Tilden mines. As of April 24, 
2015, the Tilden and Empire mines executed special electricity contracts with Wisconsin Electric Power Company.  The 
term of these contracts is through 2019. Wisconsin Electric Power Company provides 300 megawatts of electricity to 
Empire and Tilden at special rates that are regulated by the MPSC.   The pricing under these contracts is generally fixed 
except  Empire  and  Tilden  are  subject  to  frequent  changes  in  Wisconsin  Electric  Power  Company's  power  supply 
adjustment factor.   Empire and Tilden may also incur additional liabilities depending on the outcome of various proceedings 
concerning  MISO's  revised  cost  allocation  methodology  for  continued  operation  of  the  Presque  Isle  Power  Plant  in 
Michigan.    If  FERC  were  to  decide  to  award  SSR  costs  based  on  a  revised  cost  allocation  methodology  applied 
retroactively, this could result in a substantial potential liability to our Empire and Tilden mines.  

Electric power for the Hibbing and United Taconite mines is supplied by Minnesota Power.  On September 16, 
2008, the mines finalized agreements with terms from November 1, 2008 through December 31, 2015.  The agreements 
were approved by the MPUC in 2009.  The terms of the agreements included an automatic five-year extension that began 
January 1, 2016.

Silver Bay Power Company, a wholly owned subsidiary of ours, with a 115 megawatt power plant, provides the 
majority  of  Northshore’s  electrical  energy  requirements.    Silver  Bay  Power  has  an  interconnection  agreement  with 
Minnesota Power for backup power when excess generation is necessary.  

Koolyanobbing and its associated satellite mines draw power from independent diesel-fueled power stations 

and generators.  Diesel power generation capacity has been installed at the Koolyanobbing operations.

Process and Diesel Fuel

We have a long-term contract providing for the transport of natural gas on the Northern Natural Gas Pipeline for 
our U.S. Iron Ore operations.  At U.S. Iron Ore, the Empire and Tilden mines have the capability of burning natural gas, 
coal or, to a lesser extent, oil.  The Hibbing and Northshore mines have the capability to burn natural gas and oil.  The 
United Taconite mine has the ability to burn coal, natural gas and petroleum coke.  Consistent with 2015, we expect 
during 2016 our U.S. Iron Ore operations will utilize both natural gas and coal to heat furnaces and produce power at 
our Silver Bay Power facility. 

All of our mines utilize diesel fuel mainly for our mobile fleet. Como Oil and Propane supplies diesel fuel to all 

of our U.S. Iron Ore locations from the Calumet refinery in Superior, Wisconsin. Our U.S. Iron Ore locations are 
contracted with Como Oil and Propane through the end of 2018.

(2) Excludes contracted mining employees
(3) Excludes the employees on lay-off as a result of the idling of the United Taconite 

and Northshore mines. 

As of December 31, 2015, approximately 81.0 percent of our U.S. Iron Ore hourly employees were covered by 
collective bargaining agreements. This percentage includes the U.S. Iron Ore hourly employees that are on lay-off and 
excluded from the table above.

Hourly  employees  at  our  Michigan  and  Minnesota  iron  ore  mining  operations,  excluding  Northshore,  are 
represented by the USW and are covered by labor agreements between the USW and our various operating entities.  
These labor agreements that cover approximately 2,000 USW-represented employees at our Empire and Tilden mines 
in Michigan, and our United Taconite and Hibbing mines in Minnesota had an original term of September 1, 2012 through 
September 30, 2015.  We are actively negotiating with the USW for new agreements at those locations and have mutually 
extended our agreements indefinitely with either party able to terminate upon seven days’ written notice.  Employees at 
our Northshore operations are not represented by a union and are not, therefore, covered by a collective bargaining 
agreement.

Hourly employees at our Eastern Canadian Iron Ore operations also are represented by the USW.  The labor 
agreement with the USW that covers our represented employees at Bloom Lake is effective from September 1, 2013 
through August 31, 2016.  The labor agreement with the USW that covers our represented employees at our Pointe Noire 
facility, is effective from March 1, 2014 through February 28, 2020.  The costs associated with the Eastern Canadian 
Iron  Ore  employees  that  are  shown  in  the  chart  above  are  not  included  in  our  consolidated  results  due  to  the 
deconsolidation  of  our  Canadian  Entities  in  2015.    Refer  to  NOTE  14  -  DISCONTINUED  OPERATIONS  for  further 
discussion of the Canadian Entities.

Hourly  employees  at  our  Lake  Superior  and  Ishpeming  railroads  are  represented  by  seven  unions  covering 
approximately 108 employees.  The labor agreements that cover these employees reopened for bargaining on December

employees negotiate under the Railway Labor Act, which provides that labor agreements remain in force until replaced 
by a successor agreement.  Under the Railway Labor Act work stoppages cannot occur until the parties have engaged 
in substantial negotiations, have mediated any disputes and have received a release from the National Mediation Board.

Employees at our Asia Pacific Iron Ore, Corporate and Support Services are not represented by a union and 

are not, therefore, covered by collective bargaining agreements.

Safety

Safety is our primary core value as we continue toward a zero incident culture at our operating facilities.  We 
continuously monitor, track and measure our safety performance and make changes where necessary.  Best practices 
are shared globally to ensure each mine site can embed our policies, procedures and learnings for enhanced workplace 
safety.    We  measure  progress  toward  achieving  our  objective  against  regularly  established  benchmarks,  including 
measuring company-wide TRIR.  During 2015, our TRIR (including contractors) was 1.71 per 200,000 man-hours worked.

Item 1A.

Risk Factors

An  investment  in  our  common  shares  or  other  securities  is  subject  to  risk  inherent  to  our  business  and  our 
industry.  Described below are certain risks and uncertainties, the occurrences of which could have a material adverse 
effect on us.  Before making an investment decision, you should consider carefully all of the risks described below together 
with the other information included in this report.  The risks and uncertainties described below include known material 
risks that we face currently.  Although we have significant risk management policies, practices and procedures aimed to 
mitigate these risks, uncertainties may nevertheless impair our business operation.  This report is qualified in its entirety 
by these factors.

Our ERM function provides a framework for management's consideration of risk when making strategic, financial, 
operational  and/or  project  decisions.    The  framework  is  based  on  ISO  31000,  an  internationally  recognized  risk 

19

Table of Contents

management  standard.    Management  uses  a  consistent  methodology  to  identify  and  assess  risks,  determine  and 
implement risk mitigation actions, and monitor and communicate information about the Company's key risks.  Through 
these processes, we have identified six categories of risk that we are subject to:  (I) economic and market, (II) regulatory, 
(III) financial, (IV) operational, (V) development and sustainability and (VI) human capital.  The following risk factors are 
presented according to these key risk categories.  

I.  ECONOMIC AND MARKET RISKS

The volatility of commodity prices, namely iron ore and steel, affects our ability to generate revenue, maintain 
stable cash flow and to fund our operations, including growth and expansion projects.

As a mining company, our profitability is dependent upon the price of the commodities that we sell to our customers 
and the price of the products our customers sell, namely iron ore and steel prices.  The price of iron ore has fluctuated 
historically  and  is  affected  by  factors  beyond  our  control,  including:  steel  inventories;  international  demand  for  raw 
materials used in steel production; rates of global economic growth, especially construction and infrastructure activity 
that requires significant amounts of steel; recession or reduced economic activity in the United States, China, India, 
Europe and other industrialized or developing countries; uncertainties or weaknesses in global economic conditions such 
as the sovereign debt crisis in Europe and the U.S. debt ceiling; changes in production capacity of other iron ore suppliers, 
especially as additional supplies come online or where there is a significant increase in imports of steel into the United 
States or Europe; weather-related disruptions or natural disasters that may impact the global supply of iron ore; and the 
proximity, capacity and cost of infrastructure and transportation.

Our earnings, therefore, may fluctuate with the prices of the commodities we sell.  To the extent that the prices 
of iron ore and steel, including the average hot band steel price, subject to a pricing floor, significantly decline for an 
extended period of time, we may have to revise our operating plans, including curtailing production, reducing operating 
costs and capital expenditures and discontinuing certain exploration and development programs.  We also may have to 
take impairments on our assets, inventory and/or goodwill.  Sustained lower prices also could cause us to further reduce 
existing reserves if certain reserves no longer can be economically mined or processed at prevailing prices.  We may 
be unable to decrease our costs in an amount sufficient to offset reductions in revenues and may incur losses.  These 
events could have a material adverse effect on us.

Continued weaknesses in global economic conditions, reduced economic growth in China and oversupply of 
iron ore and excess steel or imported products could affect adversely our business.

The world price of iron ore is influenced strongly by global economic conditions, including international demand 
and supply for iron ore products.  In particular, the current level of international demand for raw materials used in steel 
production is driven largely by industrial growth in China.  Continued weaknesses in global economic conditions, including 
the slowing economic growth rate in China, has resulted, and could in the future result, in decreased demand for our 
products and, together with oversupply of imported products, has and may continue to lead to decreased prices, resulting 
in  lower  revenue  levels  and  decreasing  margins,  which  have  in  the  past  and  may  in  the  future  affect  adversely  our 
business and negatively impact our financial results.  For example, U.S. Iron Ore's realized revenue decreased 23 percent 
and 9 percent for the years ended December 31, 2015 and December 31, 2014, respectively, while the Fe fines spot 
price declined 43 percent and 29 percent over the same periods.  We are not able to predict whether the global economic 
conditions will continue or worsen and the impact it may have on our operations and the industry in general going forward.

In addition, due to lower demand for our products and the decline in the prices for our products, we have incurred, 
and continue to incur, operating losses.  We also have significant capital requirements, including interest payments to 
service our debt.  If we incur significant losses in future periods, we may be unable to continue as a going concern.  If 
we are unable to continue as a going concern, we may consider, among other options, restructuring our debt; however, 
there can be no assurance that these options will be undertaken and, if so undertaken, whether these efforts will succeed.

Capacity  expansions  within  the  mining  industry  could  lead  to  lower  global  iron  ore  prices,  impacting  our 
profitability.

Expected global growth of iron ore demand, particularly from China, has resulted in iron ore suppliers expanding 
their production capacity.  The supply of iron ore has increased due to these expansions.  In the current iron ore market, 
the increases in our competitors’ capacity has resulted in excess supply of these commodities, resulting in downward 
pressure on prices.  This decrease in pricing has had, and will continue to have, an adverse impact on our sales, margins 
and profitability.

If steelmakers use methods other than blast furnace production to produce steel or use other inputs, or if their 
blast furnaces shut down or otherwise reduce production, the demand for our current iron ore products may 
decrease.

Demand for our iron ore products is determined by the operating rates for the blast furnaces of steel companies.  
However, not all finished steel is produced by blast furnaces; finished steel also may be produced by other methods that 
use scrap steel, pig iron, hot briquetted iron and direct reduced iron.  North American steel producers also can produce 
steel using imported iron ore or semi-finished steel products, which eliminates the need for domestic iron ore.  Future 
environmental  restrictions  on  the  use  of  blast  furnaces  also  may  reduce  our  customers’  use  of  their  blast  furnaces.  
Maintenance of blast furnaces may require substantial capital expenditures.  Our customers may choose not to maintain, 
or may not have the resources necessary to maintain, their blast furnaces.  If our customers use methods to produce 
steel that do not use iron ore pellets, demand for our current iron ore products will decrease, which would affect adversely 
our sales, margins and profitability.

Due to economic conditions and volatility in commodity prices, or otherwise, our customers could approach 
us about modification of their supply agreements or fail to perform under such agreements.  Modifications to 
our sales agreements or our customers' failures to perform under such agreements, including modifications or 
failures  to perform due to such volatility, could impact adversely our sales, margins, profitability and cash flows.  

Although we have contractual commitments for a majority of sales in our U.S. Iron Ore business for 2016, the 
uncertainty in global economic conditions may impact adversely the ability of our customers to meet their obligations. 
As a result of such market volatility, our customers could approach us about modifying their supply agreements or fail 
to perform under such agreements. Considering our limited base of current and potential customers, any modifications 
to our sales agreements or customers' failures to perform under such agreements could impact adversely our sales, 
margins,  profitability  and  cash  flows.    For  example,  effective  October  5,  2015,  we  terminated  our  long  term  supply 
agreement with Essar as a result of Essar's multiple and material breaches under the agreement. On November 9, 2015, 
Essar filed for CCAA and Chapter 15 bankruptcy protection.  The Canadian Superior Court may require Cliffs to supply 
Essar under the terms of the agreement or other terms.  Essar moved the Canadian CCAA Court to enter an injunction 
requiring us to supply pellets.  We filed a motion to remove the case to Ohio due to the CCAA Court's lack of jurisdiction.  
On January 25, 2016, the CCAA Court determined that it has jurisdiction over the issue.  We remain open to discussing 
supplying pellets on commercially reasonable terms consistent with a just-in-time iron ore supply arrangement. In addition 
to the termination of our long term supply agreement with Essar, other potential actions by our customers could result 
in  additional  contractual  disputes  and  could  ultimately  require  arbitration  or  litigation,  either  of  which  could  be  time 
consuming and costly.  Other potential actions by our customers could also lead to a failure to renew existing contracts, 
such as our contracts with ArcelorMittal, which expire in December 2016 and January 2017.  Any such disputes and/or 
failure to renew existing contracts on favorable terms, in particular contracts with ArcelorMittal, with whom we are actively 
negotiating new contracts, could impact adversely our sales, margins, profitability and cash flows.

II.  REGULATORY RISKS

We are subject to extensive governmental regulation, which imposes, and will continue to impose, potential 
significant costs and liabilities on us.  Future laws and regulation or the manner in which they are interpreted 
and enforced could increase these costs and liabilities or limit our ability to produce iron ore products.

New  laws  or  regulations,  or  changes  in  existing  laws  or  regulations,  or  the  manner  of  their  interpretation  or 
enforcement, could increase our cost of doing business and restrict our ability to operate our business or execute our 
strategies.  This  includes,  among  other  things,  the  possible  taxation  under  U.S.  law  of  certain  income  from  foreign 
operations, compliance costs and enforcement under the Dodd-Frank Wall Street Reform and Consumer Protection Act, 
and costs associated with complying with the Patient Protection and Affordable Care Act and the Healthcare and Education 
Reconciliation Act of 2010 and the regulations promulgated thereunder. In addition, we are subject to various federal, 
provincial, state and local laws and regulations in each jurisdiction in which we have operations for human health and 
safety, air quality, water pollution, plant, wetlands, natural resources and wildlife protection, reclamation and restoration 
of mining properties, the discharge of materials into the environment, the effects that mining has on groundwater quality, 

21

Table of Contents

conductivity and availability, and related matters. Numerous governmental permits and approvals are required for our 
operations.  We  cannot  be  certain  that  we  have  been  or  will  be  at  all  times  in  complete  compliance  with  such  laws, 
regulations, permits and approvals. If we violate or fail to comply with these laws, regulations, permits or approvals, we 
could be fined or otherwise sanctioned by regulators. Compliance with the complex and extensive laws and regulations 
to which we are subject imposes substantial costs, which we expect  will continue to increase over time because of 
increased regulatory oversight, adoption of increasingly stringent environmental standards, and increased demand for 
remediation services leading to shortages of equipment, supplies and labor, as well as other factors.

Specifically, there are several notable proposed or recently enacted rulemakings or activities to which we would be 
subject or that would further regulate and/or tax our customers, namely the North American integrated steel producer 
customers that may also require us or our customers to reduce or otherwise change operations significantly or incur 
significant  additional  costs,  depending  on  their  ultimate  outcome.  These  emerging  or  recently  enacted  rules  and 
regulations include: numerous air regulations, such as climate change and greenhouse gas regulation, regional haze 
regulation, NAAQS including but not limited to those for NO2 and SO2, the CSAPR; Minnesota’s Mercury Air Emissions 
Reporting  and  Reduction  Rule,  Mercury Total  Maximum  Daily  Load  requirements  and Taconite  Mercury  Reduction 
Strategy, selenium discharge regulation; expansion of federal jurisdictional authority to regulate groundwater, and various 
other water quality regulations. Such new or more stringent legislation, regulations, interpretations or orders, when 
enacted, could have a material adverse effect on our business, results of operations, financial condition or profitability.

Although the numerous regulations, operating permits and our management systems mitigate potential 
impacts to the environment, our operations may impact inadvertently the environment or cause exposure to 
hazardous substances, which could result in material liabilities to us.

Our operations currently use and have used in the past, hazardous materials, and, from time to time, we have 
generated solid and hazardous waste.  We may be subject to claims under federal, provincial, state and local laws and 
regulations for toxic torts, natural resource damages and other damages as well as for the investigation and clean-up of 
soil, surface water, sediments, groundwater and other natural resources.  Such claims for damages and reclamation 
may arise out of current or former conditions at sites that we own, lease or operate currently, as well as sites that we or 
our acquired companies have owned, leased or operated, and at contaminated sites that have always been owned, 
leased or operated by our joint-venture partners.  Our liability for such claims may be joint and several, so that we may 
be held responsible for more than our share of the contamination or other damages, or even for the entire share.  We 
are subject to a variety of potential liability exposures arising, or otherwise involved in investigation and remediation 
activities, at certain sites. In addition to currently owned, leased or operated sites, these include sites where we formerly 
conducted iron ore and/or coal mining or processing or other operations, inactive sites that we currently own, predecessor 
sites, acquired sites, leased land sites and third-party waste disposal sites.  We may be named as a responsible party 
at other sites in the future and we cannot be certain that the costs associated with these additional sites will not be 
material.

We also could be subject to litigation for alleged bodily injuries arising from claimed exposure to hazardous 
substances allegedly used, released, or disposed of by us.  In particular, we and certain of our subsidiaries were involved 
in various claims relating to the exposure of asbestos and silica to seamen who sailed until the mid-1980s on the Great 
Lakes vessels formerly owned and operated by certain of our subsidiaries.  While several hundred of these claims against 
us had been combined in a multidistrict litigation docket and have since been dismissed and/or settled for non-material 
amounts, there remains a possibility that similar types of claims could be filed in the future.

Environmental impacts as a result of our operations, including exposures to hazardous substances or wastes 
associated with our operations, could result in costs and liabilities that could materially and adversely affect our margins, 
cash flow or profitability.  

We may be unable to obtain and renew permits necessary for our operations or be required to provide additional 
financial assurance, which could reduce our production, cash flows, profitability and available liquidity.  We 
also  could  face  significant  permit  and  approval  requirements  that  could  delay  our  commencement  or 
continuation of existing or new production operations which, in turn, could affect materially our cash flows, 
profitability and available liquidity.

Prior  to  commencement  of  mining,  we  must  submit  to  and  obtain  approval  from  the  appropriate  regulatory 
authority of plans showing where and how mining and reclamation operations are to occur.  These plans must include 
information such as the location of mining areas, stockpiles, surface waters, haul roads, tailings basins and drainage 
from mining operations.  All requirements imposed by any such authority, may be costly and time-consuming and may 
delay commencement or continuation of exploration or production operations.

22

 
Table of Contents

Mining companies must obtain numerous permits that impose strict conditions on various environmental and 
safety matters in connection with iron ore mining.  These include permits issued by various federal, state and provincial 
agencies and regulatory bodies.  The permitting rules are complex and may change over time, making our ability to 
comply with the applicable requirements more difficult or impractical and costly, possibly precluding the continuance of 
ongoing operations or the development of future mining operations.  Interpretations of rules may also change over time 
and may lead to requirements, such as additional financial assurance, making it more costly to comply.  The public, 
including special interest groups and individuals, have certain rights under various statutes to comment upon, submit 
objections to, and otherwise engage in the permitting process, including bringing citizens’ lawsuits to challenge such 
permits or mining activities.  Accordingly, required permits may not be issued or renewed in a timely fashion (or at all), 
or permits issued or renewed may be conditioned in a manner that may restrict our ability to efficiently conduct our mining 
activities, including the requirement for additional financial assurances that we may not be able to provide on commercially 
reasonable terms or at all and which would further limit our borrowing base under our ABL Facility.  Such inefficiencies 
could reduce our production, cash flows, profitability and available liquidity.

III. 

FINANCIAL RISKS

A substantial majority of our sales are made under term supply agreements to a limited number of customers 
that contain price-adjustment clauses that could affect adversely the stability and profitability of our operations.

For the twelve months ended December 31, 2015, a majority of our U.S. Iron Ore sales and our Asia Pacific Iron 
Ore sales were made under term supply agreements to a limited number of customers.  More than 72 percent of our 
revenue is derived from the North American integrated steel industry.  For the twelve months ended December 31, 2015, 
three customers together accounted for more than 93 percent of our U.S. Iron Ore product sales revenues (representing 
70 percent of our consolidated revenues). Our Asia Pacific Iron Ore contracts are due to expire at various dates until 
March 2017 for the majority of our Chinese customers and March 2016 for the remainder of our Chinese customers and 
our Japanese and Korean customers. As of December 31, 2015, our U.S. Iron Ore contracts had an average remaining 
duration of approximately three years. Although we have contractual commitments for a majority of sales in our U.S. Iron 
Ore business for 2016, the uncertainty in global economic conditions may adversely impact the ability of our customers 
to meet their obligations.  For example, of the potential customers in the North American integrated steel industry, two 
are in reorganization, and certain others have experienced financial difficulties.  We cannot be certain that we will be 
able to renew or replace existing term supply agreements at approximately the same volume levels, prices or with similar 
profit margins when they expire. A loss of sales to our existing customers could have a substantial negative impact on 
our sales, margins, cash flows and profitability.

Our existing and future indebtedness may limit cash flow available to invest in the ongoing needs of our business, 
which could prevent us from fulfilling our obligations under our senior notes.

As of December 31, 2015, we had an aggregate principal amount of $2,898.2 million of total debt, $1,084.2 
million of which was secured (excluding outstanding letters of credit, $97 million of equipment loans, and $74 million of 
capital leases), and $285.2 million of cash on our balance sheet.  As of December 31, 2015, no loans were drawn under 
the credit facility and we had total availability of $366.0 million as a result of borrowing base limitations.  As of December 
31, 2015, the principal amount of letters of credit obligations totaled $186.3 million and foreign exchange hedge obligations 
totaled $0.5 million, thereby further reducing available borrowing capacity on our credit facility to $179.2 million.  

Our substantial level of indebtedness has required us to dedicate a substantial portion of our cash flow from 
operations  to  the  payment  of  debt  service,  reducing  the  availability  of  our  cash  flow  to  fund  working  capital,  capital 
expenditures, acquisitions and other general corporate purposes.  Moreover, our level of indebtedness could have further 
consequences, including, increasing our vulnerability to adverse economic or industry conditions, limiting our ability to 
obtain additional financing in the future to enable us to react to changes in our business, or placing us at a competitive 
disadvantage compared to businesses in our industry that have less indebtedness.

Our substantial level of indebtedness could limit our ability to obtain additional financing on acceptable terms or 
at all for working capital, capital expenditures and general corporate purposes. Our liquidity needs could vary significantly 
and may be affected by general economic conditions, industry trends, performance and many other factors not within 
our control. If we are unable to generate sufficient cash flow from operations in the future to service our debt, we may 
be required to refinance all or a portion of our existing debt. However, we may not be able to obtain any such new or 
additional debt on favorable terms or at all.

Any failure to comply with covenants in the instruments governing our debt could result in an event of default 

which, if not cured or waived, would have a material adverse effect on us.

23

 
Table of Contents

We may not be able to generate sufficient cash to service all of our debt, and may be forced to take other actions 
to satisfy our obligations under our debt, which may not be successful.

Our ability to make scheduled payments on or to refinance our debt obligations, including our senior notes, and 
to fund planned capital expenditures and expansion efforts and any strategic alliances or acquisitions we may make in 
the future depends on our ability to generate cash in the future and our financial condition and operating performance, 
which are subject to prevailing economic and competitive conditions and to certain financial, business and other factors 
beyond our control. We cannot assure you that we will maintain a level of cash flows from operating activities sufficient 
to permit us to pay the principal, premium, if any, and interest on our debt, including our senior notes.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to 
reduce or delay investments and capital expenditures, or to sell assets, seek additional capital or restructure or refinance 
our debt, including our senior notes. Any refinancing of our debt could be at higher interest rates and may require us to 
comply with more onerous covenants, which could further restrict our business operations. These measures may not be 
successful and may not permit us to meet our scheduled debt service obligations. If our operating results and available 
cash are insufficient to meet our debt service obligations, we could face substantial liquidity problems and might be 
required to dispose of material assets or operations to meet our debt service and other obligations. We may not be able 
to consummate those dispositions or to obtain the proceeds that we could realize from them, and these proceeds may 
not be adequate to meet any debt service obligations then due. Further, we may need to refinance all or a portion of our 
debt on or before maturity, and we may not be able to refinance any of our debt on commercially reasonable terms or 
at all.  Additionally, additional or new financial assurances may be demanded by our vendors or regulatory agencies that 
we may not be able to provide on commercially reasonable terms or at all.

Changes in credit ratings issued by nationally recognized statistical rating organizations could affect 
adversely our cost of financing and the market price of our securities.

Credit  rating  agencies  could  further  downgrade  our  ratings  either  due  to  factors  specific  to  our  business,  a 
prolonged cyclical downturn in the mining industry, or macroeconomic trends (such as global or regional recessions) and 
trends in credit and capital markets more generally.  The interest rate payable on our senior notes is subject to adjustment 
in the event of a change in the credit ratings and is currently at the maximum interest rate of 5.95 percent per annum. 
Any further decline in our credit ratings would likely result in an increase to our cost of financing, limit our access to the 
capital markets, significantly harm our financial condition and results of operations, hinder our ability to refinance existing 
indebtedness on acceptable terms and have an adverse effect on the market price of our securities.

We rely on our joint venture partners in our mines to meet their payment obligations and we are subject to risks 
involving the acts or omissions of our joint venture partners when we are not the manager of the joint venture.

We co-own and manage three of our five U.S. Iron Ore mines with various joint venture partners that are integrated 
steel producers or their subsidiaries, including ArcelorMittal and U.S. Steel.  We rely on our joint venture partners to 
make their required capital contributions and to pay for their share of the iron ore that each joint venture produces.  Our 
U.S. Iron Ore joint venture partners are often also our customers.  If one or more of our joint venture partners fail to 
perform their obligations, the remaining joint venture partners, including ourselves, may be required to assume additional 
material obligations, including significant capital contribution, pension and postretirement health and life insurance benefit 
obligations.  The premature closure of a mine due to the failure of a joint venture partner to perform its obligations could 
result in significant fixed mine-closure costs, including severance, employment legacy costs and other employment costs; 
reclamation and other environmental costs; and the costs of terminating long-term obligations, including energy and 
transportation contracts and equipment leases.  For example, with respect to one of our two Eastern Canadian Iron Ore 
mines, the Bloom Lake mine, CQIM's joint venture partner did not fully participate in calls for capital contributions, resulting 
in additional financial burden for CQIM.  This additional burden was one of multiple factors in CQIM's decision to file for 
a stay under CCAA.

We cannot control the actions of our joint venture partners, especially when we have a minority interest in a joint 
venture.  Further, in spite of performing customary due diligence prior to entering into a joint venture, we cannot guarantee 
full disclosure of prior acts or omissions of the sellers or those with whom we enter into joint ventures.  Such risks could 
have a material adverse effect on the business, results of operations or financial condition of our joint venture interests.

We may not be able to recover the carrying value when divesting assets or businesses.

When we divest assets or businesses, we may not be able to recover the carrying value of these assets, which 
potentially could have a material adverse impact on our results of operations, shareholders' equity and capital structure. 
Also, if we were to sell a percentage of a business, there are inherent risks of a joint venture relationship as noted in the 
risk factor above.

Our ability to collect payments from our customers depends on their creditworthiness.

Our ability to receive payment for products sold and delivered to our customers depends on the creditworthiness 
of our customers. With respect to our Asia Pacific business unit, payment typically is received as the products are shipped 
and much of the product is secured by bank letters of credit. By contrast, in our U.S. Iron Ore business unit, generally, 
we deliver iron ore products to our customers’ facilities in advance of payment for those products. Under this practice 
for our U.S. customers, title and risk of loss with respect to U.S. Iron Ore products does not pass to the customer until 
payment for the pellets is received; however, there is typically a period of time in which pellets, for which we have reserved 
title, are within our customers’ control. Where we have identified credit risk with certain customers, we have put in place 
alternate payment terms from time to time.

Consolidations in some of the industries in which our customers operate have created larger customers.  These 
factors have caused some customers to be less profitable and increased our exposure to credit risk.  Customers in other 
countries may be subject to other pressures and uncertainties that may affect their ability to pay, including trade barriers, 
exchange controls, and local, economic and political conditions.  Downturns in the economy and disruptions in the global 
financial markets in recent years have affected the creditworthiness of our customers from time to time. Some of our 
customers  are  highly  leveraged.    If  economic  conditions  worsen  or  prolonged  global,  national  or  regional  economic 
recession conditions return, it is likely to impact significantly the creditworthiness of our customers and could, in turn, 
increase the risk we bear on payment default for the credit we provide to our customers and could limit our ability to 
collect receivables.  Failure to receive payment from our customers for products that we have delivered could affect 
adversely our results of operations, financial condition and liquidity.

Our operating expenses could increase significantly if the price of electrical power, fuel or other energy sources 
increases.

Our mining operations require significant use of energy.  Operating expenses at all of our mining locations are 
sensitive to changes in electricity prices and fuel prices, including diesel fuel and natural gas prices.  These items make 
up approximately 25 to 30 percent in the aggregate of our operating costs in our U.S. Iron Ore locations, for example.  
Prices for electricity, natural gas and fuel oils can fluctuate widely with availability and demand levels from other users.  
During periods of peak usage, supplies of energy may be curtailed and we may not be able to purchase them at historical 
rates.  A disruption in the transmission of energy, inadequate energy transmission infrastructure, or the termination of 
any of our energy supply contracts could interrupt our energy supply and affect adversely our operations.  While we have 
some long-term contracts with electrical suppliers, we are exposed to fluctuations in energy costs that can affect our 
production costs.  As an example, our mines in Minnesota are subject to changes in Minnesota Power’s rates, such as 
rate changes that are reviewed and approved by the state public utilities commission in response to an application filed 
by Minnesota Power.  We also enter into market-based pricing supply contracts for  natural gas and diesel fuel for use 
in our operations.  Those contracts expose us to price increases in energy costs, which could cause our profitability to 
decrease significantly. We are estimating that power rates for our electricity-intensive operations could increase above 
2015 levels by up to 9.75 percent by 2020, representing an increase of approximately $6 per MWh by 2020 for our U.S. 
operations.

In addition, U.S. public utilities are expected to pass through additional capital and operating cost increases 
related to new or pending U.S. environmental regulations that are expected to require significant capital investment and 
use  of  cleaner  fuels  in  the  future  and  which  may  impact  U.S.  coal-fired  generation  capacity.  These  environmental 
regulations could force the future closure of the Presque Isle Power Plant in the Upper Peninsula of Michigan which 
supplies electricity to our mines in Michigan.

The availability of capital may be limited.

We may need to access the capital markets to finance ongoing operations, any development of existing mining 
properties and our other cash requirements. Our substantial indebtedness could make it more difficult for us to borrow 
money in the future and may reduce the amount of money available to finance our operations and other business activities 
and may have other detrimental consequences, including the following: requiring us to dedicate a substantial portion of 
our cash flow from operations to the payment of principal, premium, if any, and interest on our debt, which will reduce 
funds available for other purposes; exposing us to the risk of increased interest costs if the underlying interest rates rise 
on our existing credit facility or other variable rate debt; making it more difficult to obtain surety bonds, letters of credit 
or other financing, particularly during periods in which credit markets are weak; causing a decline in our credit ratings; 
limiting our ability to compete with companies that are not as leveraged and that may be better positioned to withstand 
economic downturns; and limiting our flexibility in planning for, or reacting to, and increasing our vulnerability to, changes 
in our business, the industry in which we compete and general economic and market conditions.  If we further increase 
our indebtedness, the related risks that we now face, including those described above, could intensify.  We cannot predict 
the general availability or accessibility of capital to finance projects in the future.

We are subject to a variety of financial market risks.

Financial market risks include those caused by changes in the value of investments, changes in commodity 
prices, interest rates and foreign currency exchange rates.  We have established policies and procedures to manage 
such risks; however, certain risks are beyond our control and our efforts to mitigate such risks may not be effective.  
These factors could have a material adverse effect on our results of operations.

We are subject to bankruptcy risks relating to our Canadian operations.

As previously disclosed, the Bloom Lake Group commenced the CCAA process in January 2015 to address the 
Bloom Lake Group's immediate liquidity issues and to preserve and protect its assets for the benefit of all stakeholders 
while  restructuring  and/or  sale  options  are  explored.    In  May  2015,  the  Wabush  Group  commenced  restructuring 
proceedings and, as a result, the CCAA protection granted to the Bloom Lake Group has been extended to include the 
Wabush Group.  Certain obligations of the Bloom Lake Group, including equipment loans, are guaranteed by Cliffs.  
Financial instruments are posted by Cliffs to support certain reclamation obligations of the Wabush Group.  It is possible 
that (a) as part of the CCAA process (i) claims may be asserted by or on behalf of the Bloom Lake Group or the Wabush 
Group against non-debtor affiliates of the Bloom Lake Group and the Wabush Group and/or (ii) claims of non-debtor 
affiliates against the Bloom Lake Group or the Wabush Group may be challenged and (b) creditors of the Bloom Lake 
Group or the Wabush Group may assert claims against non-debtor affiliates of the Bloom Lake Group or the Wabush 
Group under the guarantees discussed above.  While we anticipate the restructuring and/or sale of the Bloom Lake 
Group and the Wabush Group assets may mitigate these risks, to the extent that any claims are successful or the Bloom 
Lake Group’s obligations guaranteed by Cliffs are not satisfied in full by any such restructuring or sale, Cliffs could be 
held liable for certain obligations.

A court or regulatory body could find that we are responsible, in whole or in part, for liabilities we transferred 
to other entities.

As part of our strategy to focus on our U.S. iron ore operations we have sold or otherwise disposed of several 
non-core assets.  Some of the transactions under which we sold or otherwise disposed of our non-core assets included 
provisions transferring certain liabilities to the purchasers or acquirers of those non-core assets.  While we believe that 
all such transfers were completed properly and are legally binding, we may be at risk that some court or regulatory body 
could disagree and determine that we remain responsible for liabilities we intended to and did transfer.

IV.  OPERATIONAL RISKS

Mine closures entail substantial costs.  If we close one or more of our mines, our results of operations and 
financial condition would likely be affected adversely.

If we close any of our mines, our revenues would be reduced unless we were able to increase production at our 
other mines, which may not be possible.  The closure of a mining operation involves significant fixed closure costs, 
including accelerated employment legacy costs, severance-related obligations, reclamation and other environmental 
costs, and the costs of terminating long-term obligations, including customer, energy and transportation contracts and 
equipment leases.  We base our assumptions regarding the life of our mines on detailed studies we perform from time 
to time, but those studies and assumptions are subject to uncertainties and estimates that may not be accurate.  We 
recognize the costs of reclaiming open pits, stockpiles, tailings ponds, roads and other mining support areas based on 
the estimated mining life of our property.  If we were to significantly reduce the estimated life of any of our mines, the 
mine-closure costs would be applied to a shorter period of production, which would increase costs per ton produced and 
could significantly and adversely affect our results of operations and financial condition.

A North American mine permanent closure could accelerate and significantly increase employment legacy costs, 
including our expense and funding costs for pension and other postretirement benefit obligations.  A number of employees 
would be eligible for immediate retirement under special eligibility rules that apply upon a mine closure.  All employees 
eligible for immediate retirement under the pension plans at the time of the permanent mine closure also could be eligible 
for postretirement health and life insurance benefits, thereby accelerating our obligation to provide these benefits.  Certain 
mine closures would precipitate a pension closure liability significantly greater than an ongoing operation liability.  Finally, 
a permanent mine closure could trigger severance-related obligations, which can equal up to sixteen weeks of pay per 
employee in some jurisdictions, depending on length of service.  As a result, the closure of one or more of our mines 
could adversely affect our financial condition and results of operations.

At the end of March 2014, we idled our Wabush Scully mine in Newfoundland and Labrador, and in the fourth 
quarter of 2014, we began to implement the permanent closure plan for the mine. Additionally, we disclosed in November 
2014 that we were pursuing exit options for our Bloom Lake mine and as disclosed in January 2015, active production 
at Bloom Lake mine completely ceased and the mine transitioned to "care-and-maintenance" mode.  To mitigate closure 
costs in connection with the potential shutdown of the Bloom Lake mine, our Canadian affiliates that operate the mine 
commenced restructuring proceedings under the CCAA.  However, there can be no assurance that we will not have any 
material obligations in connection with the potential shutdown of the Bloom Lake mine despite the CCAA filing.

Our  sales  and  competitive  position  depend  on  the  ability  to  transport  our  products  to  our  customers  at 
competitive rates and in a timely manner.

In our U.S. Iron Ore operations, disruption of the lake and rail transportation services because of weather-related 
problems, including ice and winter weather conditions on the Great Lakes or St. Lawrence Seaway, climate change, 
strikes, lock-outs, or other events and lack of alternative transportation sources, could impair our ability to supply iron 
ore to our customers at competitive rates or in a timely manner and, thus, could adversely affect our sales, margins and 
profitability.  Further,  reduced  dredging  and  environmental  changes,  particularly  at  Great  Lakes  ports,  could  impact 
negatively our ability to move our iron ore products because lower water levels restrict the tonnage that vessels can haul, 
resulting in higher freight rates.

Our Asia Pacific Iron Ore operations also are dependent upon rail and port capacity. Disruptions in rail service 
or availability of dock capacity could similarly impair our ability to supply iron ore to our customers, thereby adversely 
affecting our sales and profitability. In addition, our Asia Pacific Iron Ore operations are also in direct competition with 
the major world seaborne exporters of iron ore and our customers face higher transportation costs than most other 
Australian producers to ship our products to the Asian markets because of the location of our major shipping port on 
the south coast of Australia. Further, increases in transportation costs, including volatile fuel rates, decreased availability 
of ocean vessels or changes in such costs relative to transportation costs incurred by our competitors could make our 
products less competitive, restrict our access to certain markets and have an adverse effect on our sales, margins and 
profitability.

27

Table of Contents

Natural  disasters,  weather  conditions, disruption of  energy,  unanticipated geological  conditions,  equipment 
failures, and other unexpected events may lead our customers, our suppliers or our facilities to curtail production 
or shut down operations.

Operating levels within the mining industry are subject to unexpected conditions and events that are beyond the 
industry’s control.  Those events could cause industry members or their suppliers to curtail production or shut down a 
portion or all of their operations, which could reduce the demand for our iron ore products, and could affect adversely 
our sales, margins and profitability.

Interruptions in production capabilities inevitably will increase our production costs and reduce our profitability.  
We  do  not  have  meaningful  excess  capacity  for  current  production  needs,  and  we  are  not  able  to  quickly  increase 
production or re-start production at one mine to offset an interruption in production at another mine.  Additionally, re-start 
production costs can be even higher if required to be taken during extremely cold weather conditions.

A portion of our production costs are fixed regardless of current operating levels. As noted, our operating levels 
are subject to conditions beyond our control that can delay deliveries or increase the cost of mining at particular mines 
for varying lengths of time. These include weather conditions (for example, extreme winter weather, tornadoes, floods, 
and the lack of availability of process water due to drought) and natural and man-made disasters, pit wall failures, 
unanticipated geological conditions, including variations in the amount of rock and soil overlying the deposits of iron 
ore, variations in rock and other natural materials and variations in geologic conditions and ore processing changes.

The manufacturing processes that take place in our mining operations, as well as in our processing facilities, 
depend on critical pieces of equipment. This equipment may, on occasion, be out of service because of unanticipated 
failures. In addition, many of our mines and processing facilities have been in operation for several decades, and the 
equipment is aged. In the future, we may experience additional material plant shutdowns or periods of reduced production 
because of equipment failures. Further, remediation of any interruption in production capability may require us to make 
large capital expenditures that could have a negative effect on our profitability and cash flows. Our business interruption 
insurance would not cover all of the lost revenues associated with equipment failures. Longer-term business disruptions 
could result in a loss of customers, which adversely could affect our future sales levels and, therefore, our profitability.

Regarding the impact of unexpected events happening to our suppliers, many of our mines are dependent on 
one source for electric power and for natural gas. A significant interruption in service from our energy suppliers due to 
terrorism or sabotage, weather conditions, natural disasters, or any other cause can result in substantial losses that 
may not be fully recoverable, either from our business interruption insurance or responsible third parties.

We are subject to risks involving operations and sales in multiple countries.

We supply raw materials to the global integrated steel industry with substantial assets located outside of the 
U.S.  We conduct operations in the U.S. and Australia.  As such, we are subject to additional risks beyond those relating 
to our U.S. operations, such as fluctuations in currency exchange rates; potentially adverse tax consequences due to 
overlapping  or  differing  tax  structures;  burdens  to  comply  with  multiple  and  potentially  conflicting  foreign  laws  and 
regulations,  including  export  requirements,  tariffs,  economic  sanctions  and  other  barriers,  environmental  health  and 
safety requirements, and unexpected changes in any of these laws and regulations; the imposition of duties, tariffs, 
import and export controls and other trade barriers impacting the seaborne iron ore markets; difficulties in staffing and 
managing  multi-national  operations;  political  and  economic  instability  and  disruptions,  including  terrorist  attacks; 
disadvantages of competing against companies from countries that are not subject to U.S. laws and regulations, including 
the  Foreign  Corrupt  Practices  Act;  and  uncertainties  in  the  enforcement  of  legal  rights  and  remedies  in  multiple 
jurisdictions.  If we are unable to manage successfully the risks associated with operating our global business, these 
risks could have a material adverse effect on our business, results of operations or financial condition.

Our profitability could be affected adversely by the failure of outside contractors to perform.

Asia Pacific Iron Ore uses contractors to handle many of the operational phases of their mining and processing 
operations and, therefore, we are subject to the performance of outside companies on key production areas.  A failure 
of any of these contractors to perform in a significant way would result in additional costs for us, which also could affect 
adversely our production rates and results of operations.

We may not be able to complete divestitures of our non-core assets at acceptable prices or at all.

As an extension of our re-focused U.S. Iron Ore strategy, we are currently in the process of streamlining our 
portfolio of non-core assets.  Asia Pacific Iron Ore has been identified as a non-core asset and will be considered for 
monetization.  However, we may not be able to sell any non-core assets at sales prices acceptable to us or at all.  Gains 

28

 
Table of Contents

or losses on the sales of, or lost operating income from, non-core assets may affect our profitability.  Moreover, we may 
incur asset impairment charges related to divestitures that reduce our profitability. Our divestiture activities may also 
present financial, managerial and operational risks.  Those risks include diversion of management attention from existing 
businesses,  difficulties  separating  personnel  and  financial  and  other  systems,  adverse  effects  on  existing  business 
relationships  with  suppliers  and  customers.   Any  of  these  factors  could  affect  our  financial  condition  and  results  of 
operations.

V. 

DEVELOPMENT AND SUSTAINABILITY RISKS

The cost and time to implement a strategic capital project may prove to be greater than originally anticipated. 

We  undertake  strategic  capital  projects  in  order  to  enhance,  expand  or  upgrade  our  mines  and  production 
capabilities.    Our ability  to achieve  the anticipated  volumes  of  production,  revenues  or  otherwise  realize  acceptable 
returns on strategic capital projects that we may undertake is subject to a number of risks, many of which are beyond 
our control, including a variety of market (such as a volatile pricing environment for iron ore), operational, permitting and 
labor-related factors.  Further, the cost to implement any given strategic capital project ultimately may prove to be greater 
and may take more time than originally anticipated.  Inability to achieve the anticipated results from the implementation 
of our strategic capital projects, or the incurring of unanticipated implementation costs, penalties or inability to meet 
contractual obligations could affect adversely our results of operations and future earnings and cash flow generation.

We continually must replace reserves depleted by production.  Exploration activities may not result in additional 
discoveries.

Our ability to replenish our ore reserves is important to our long-term viability.  Depleted ore reserves must be 
replaced by further delineation of existing ore bodies or by locating new deposits in order to maintain production levels 
over the long term.  Resource exploration and development are highly speculative in nature.  Exploration projects involve 
many risks, require substantial expenditures and may not result in the discovery of sufficient additional mineral deposits 
that can be mined profitably.  Once a site with mineralization is discovered, it may take several years from the initial 
phases  of  drilling  until  production  is  possible,  during  which  time  the  economic  feasibility  of  production  may  change.  
Substantial expenditures are required to establish recoverable proven and probable reserves and to construct mining 
and processing facilities.  As a result, there is no assurance that current or future exploration programs will be successful 
and there is a risk that depletion of reserves will not be offset by discoveries or acquisitions.  Given current market 
conditions, we have curtailed substantially any expenditures related to exploration at or near our mine sites.

We rely on estimates of our recoverable reserves, which is complex due to geological characteristics of the 
properties and the number of assumptions made.

We  regularly  evaluate  our  iron  ore  reserves  based  on  revenues  and  costs  and  update  them  as  required  in 
accordance  with  SEC  Industry  Guide  7  and  historically,  the  Canadian  Institute  of  Mining,  Metallurgy  &  Petroleum's 
Definition Standards on Mineral Resources and Mineral Reserves.  In addition, our Asia Pacific Iron Ore business segment 
has published reserves that follow the Joint Ore Reserve Code in Australia, with certain changes to our Western Australian 
reserve values to make them comply with SEC requirements.  There are numerous uncertainties inherent in estimating 
quantities of reserves of our mines, including many factors beyond our control.

Estimates of reserves and future net cash flows necessarily depend  upon a number of variable factors and 
assumptions, such as production capacity, effects of regulations by governmental agencies, future prices for iron ore, 
future industry conditions and operating costs, severance and excise taxes, development costs and costs of extraction 
and reclamation, all of which may vary considerably from actual results.  Estimating the quantity and grade of reserves 
requires us to determine the size, shape and depth of our mineral bodies by analyzing geological data, such as samplings 
of  drill  holes.  In  addition  to  the  geology  assumptions  of  our  mines,  assumptions  are  also  required  to  determine  the 
economic feasibility of mining these reserves, including estimates of future commodity prices and demand, the mining 
methods we use, and the related costs incurred to develop and mine our reserves. For these reasons, estimates of the 
economically  recoverable  quantities  of  mineralized  deposits  attributable  to  any  particular  group  of  properties, 
classifications of such reserves based on risk of recovery and estimates of future net cash flows prepared by different 
engineers  or  by  the  same  engineers  at  different  times  may  vary  substantially  as  the  criteria  change.  Estimated  ore 
reserves could be affected by future industry conditions, geological conditions and ongoing mine planning. Actual volume 
and grade of reserves recovered, production rates, revenues and expenditures with respect to our reserves will likely 
vary from estimates, and if such variances are material, our sales and profitability could be affected adversely.

29

 
 
 
 
Table of Contents

Defects in title or loss of any leasehold interests in our properties could limit our ability to mine these 
properties or result in significant unanticipated costs. 

A portion of our mining operations are conducted on properties we lease, license or as to which we have easements 
or  other  possessory  interests  ("leased  properties").  Consistent  with  industry  practice,  title  to  most  of  these  leased 
properties and mineral rights are not usually verified until we make a commitment to develop a property, which may not 
occur until after we have obtained necessary permits and completed exploration of the leased property.  In some cases, 
title with respect to leased properties is not verified at all because we instead rely on title information or representations 
and warranties provided by lessors or grantors.  We do not maintain title insurance on our owned or leased properties.  
A title defect or the loss of any lease, license or easement for any leased property could adversely affect our ability to 
mine the associated reserves.  In addition, from time to time the rights of third parties for competing uses of adjacent, 
overlying, or underlying lands such as for, roads, easements and public facilities may affect our ability to operate as 
planned if our title is not superior or arrangements cannot be negotiated. 

Any challenge to our title could delay the exploration and development of some reserves, deposits or surface 
rights, cause us to incur unanticipated costs and could ultimately result in the loss of some or all of our interest in those 
reserves or surface rights.  In the event we lose reserves, deposits or surface rights, we may have to shut down or 
significantly alter the sequence of our mining operations, which may adversely affect our future production, revenues 
and cash flows.  Additionally, if we lose any leasehold interests relating to any of our pellet plants or loadout facilities, 
we may need to find an alternative location to process our iron ore and load it for delivery to customers, which could 
result in significant unanticipated costs.  Finally, we could incur significant liability if we inadvertently mine on property 
we do not own or lease.

In order to continue to foster growth in our business and maintain stability of our earnings, we must maintain 
our social license to operate with our stakeholders.

As a mining company, maintaining a strong reputation and consistent operational and safety history is vital in 
order to continue to foster growth and maintain stability in our earnings. As sustainability expectations increase and 
regulatory requirements continue to evolve, maintaining our social license to operate becomes increasingly important. 
We strive to incorporate social license expectations in our ERM program. Our ability to maintain our reputation and strong 
operating history could be threatened, including by circumstances outside of our control. If we are not able to respond 
effectively to these and other challenges to our social license to operate, our reputation could be damaged significantly. 
Damage to our reputation could affect adversely our operations and ability to foster growth in our Company.

Estimates and timelines relating to new development and expansion projects are uncertain and we may incur 
higher costs and lower economic returns than estimated.

Mine development and expansion projects typically require a number of years and significant expenditures during 
the development or expansion phase before production is possible.  Such projects could experience unexpected problems 
and delays during development, construction and mine start-up or expansion.

Our  decision  to  develop  a  project  typically  is  based  on  the  results  of  feasibility  studies,  which  estimate  the 
anticipated economic returns of a project.  The actual project profitability or economic feasibility may differ from such 
estimates  as  a  result  of  any  of  the  following  factors,  among  others:  changes  in  tonnage,  grades  and  metallurgical 
characteristics  of  ore  to  be  mined  and  processed;  estimated  future  prices  of  the  relevant  ore;  changes  in  customer 
demand; higher construction and infrastructure costs; the quality of the data on which engineering assumptions were 
made; higher production costs; adverse geotechnical conditions; availability of adequate labor force; availability and cost 
of water and power; availability and cost of transportation; fluctuations in inflation and currency exchange rates; availability 
and terms of financing; delays in obtaining environmental or other government permits or changes in laws and regulations 
including environmental laws and regulations; weather or severe climate impacts; and potential delays relating to social 
and community issues.

Our future development activities may not result in the expansion or replacement of current production with new 
production, or any such new production sites or facilities may be less profitable than currently anticipated, or may not 
be profitable at all, any of which could have a material adverse effect on our sales, margins and cash flows.

VI.  HUMAN CAPITAL RISKS

Our profitability could be affected adversely if we fail to maintain satisfactory labor relations.

Production in our mines is dependent upon the efforts of our employees.  We are party to labor agreements with 
various labor unions that represent employees at our operations.  Such labor agreements are negotiated periodically, 
and, therefore, we are subject to the risk that these agreements may not be able to be renewed on reasonably satisfactory 
terms.  It is difficult to predict what issues may arise as part of the collective bargaining process, and whether negotiations 
concerning these issues will be successful.  Due to union activities or other employee actions, we could experience labor 
disputes, work stoppages, or other disruptions in our production of iron ore that could affect us adversely.  The USW 
represents all hourly employees at our U.S. Iron Ore and Eastern Canadian Iron Ore operations owned and/or managed 
by Cliffs or its subsidiary companies except for Northshore.  Our labor agreements with the USW at four of our U.S. Iron 
Ore operations expired on October 1, 2015, and have since been extended indefinitely.  We continue to bargain with the 
USW in good faith with the expectation that we will be able to reach a mutually acceptable long-term extension of our 
agreements.  At this time, we do not anticipate any type of labor disruption but since we are currently unable to estimate 
when our labor agreements will be finalized, there is an increased possibility of a disruption at our U.S. Iron Ore operations 
in 2016.

If we enter into a new labor agreement with any union that significantly increases our labor costs relative to our 
competitors or fail to come to an agreement upon expiry, our ability to compete may be materially and adversely affected.

We may encounter labor shortages for critical operational positions, which could affect adversely our ability to 
produce our products.

We are predicting a long-term shortage of skilled workers for the mining industry and competition for the available 
workers limits our ability to attract and retain employees.  Additionally, at our U.S. mining locations, many of our mining 
operational employees are approaching retirement age.  As these experienced employees retire, we may have difficulty 
replacing them at competitive wages.

Our expenditures for post-retirement benefit and pension obligations could be materially higher than we have 
predicted if our underlying assumptions differ from actual outcomes, there are mine closures, or our joint venture 
partners fail to perform their obligations that relate to employee pension plans.

We provide defined benefit pension plans and OPEB to certain eligible union and non-union employees in the 
United States, including our share of expense and funding obligations with respect to unconsolidated ventures.  Our 
pension expense and our required contributions to our pension plans are affected directly by the value of plan assets, 
the projected and actual rate of return on plan assets, and the actuarial assumptions we use to measure our defined 
benefit pension plan obligations, including the rate at which future obligations are discounted.

We cannot predict whether changing market or economic conditions, regulatory changes or other factors will 

increase our pension expenses or our funding obligations, diverting funds we would otherwise apply to other uses.

We have calculated our unfunded pension and OPEB obligations based on a number of assumptions. If our 
assumptions  do  not  materialize  as  expected,  cash  expenditures  and  costs  that  we  incur  could  be  materially  higher. 
Moreover, we cannot be certain that regulatory changes will not increase our obligations to provide these or additional 
benefits.  These obligations also may increase substantially in the event of adverse medical cost trends or unexpected 
rates of early retirement, particularly for bargaining unit retirees. 

We depend on our senior management team and other key employees, and the loss of these employees could 
adversely affect our business.

Our success depends in part on our ability to attract and motivate our senior management and key employees.  
Achieving this objective may be difficult due to a variety of factors, including fluctuations in the global economic and 
industry conditions, competitors’ hiring practices, cost reduction activities, and the effectiveness of our compensation 
programs.  Competition for qualified personnel can be intense.  We must continue to recruit, retain, and motivate our 
senior management and key personnel in order to maintain our business and support our projects.  A loss of senior 
management and key personnel could prevent us from capitalizing on business opportunities, and our operating results 
could be adversely affected.

Properties

The following map shows the locations of our operations and offices as of December 31, 2015: 

General Information about the Mines

All of our iron ore mining operations are open-pit mines.  Additional pit development is underway as required by 
long-range mine plans.  At our U.S. Iron Ore and Asia Pacific Iron Ore mines, drilling programs are conducted periodically 
for the purpose of refining guidance related to ongoing operations.

Geologic models are developed for all mines to define the major ore and waste rock types.  Computerized block 
models for iron ore are constructed that include all relevant geologic and metallurgical data.  These are used to generate 
grade and tonnage estimates, followed by detailed mine design and life of mine operating schedules.

U.S. Iron Ore

The following map shows the locations of our U.S. Iron Ore operations as of December 31, 2015:

We directly or indirectly own and operate interests in five U.S. Iron Ore mines located in Michigan and Minnesota 
from which we produced 19.3 million, 22.4 million and 20.3 million tons of iron ore pellets in 2015, 2014 and 2013, 
respectively, for our account.  We produced 6.8 million, 7.3 million and 6.9 million tons, respectively, on behalf of the 
steel company partners of the mines.

Our U.S. Iron Ore mines produce from deposits located within the Biwabik and Negaunee Iron Formation, which 
are classified as Lake Superior type iron formations that formed under similar sedimentary conditions in shallow marine 
basins approximately two billion years ago.  Magnetite and hematite are the predominant iron oxide ore minerals present, 
with lesser amounts of goethite and limonite.  Quartz is the predominant waste mineral present, with lesser amounts of 

32

other chiefly iron bearing silicate and carbonate minerals.  The ore minerals liberate from the waste minerals upon fine 
grinding.

3 2015 Production from Empire includes 0.8 million long tons tolled to Tilden.

Empire Mine 

The Empire mine is located on the Marquette Iron Range in Michigan’s Upper Peninsula approximately 15 miles 
southwest of Marquette, Michigan.  The Empire mine has produced between 3.0 million and 4.4 million tons of iron ore 
pellets annually over the past five years, of which between 0.8 million and 2.4 million tons annually over the past five 
years were tolled to Tilden mine.  During 2015, Empire was temporarily idled for a summer shutdown beginning on June 
26, 2015. The temporary idle ended during mid-October of 2015.  The summer shutdown was required due to lower 
tolling requirements from Tilden mine, a result of reduced demand from our steel-producing customers.

We own 79 percent of Empire and a subsidiary of ArcelorMittal USA has retained the remaining 21 percent 
ownership in Empire with limited rights and obligations, which it has a unilateral right to put to us at any time.  This right 
has not been exercised.  Each partner takes its share of production pro rata; however, provisions in the partnership 
agreement allow additional or reduced production to be delivered under certain circumstances.  As part of a 2014 extension 
agreement between us and ArcelorMittal, which amended certain terms of the partnership agreement, certain minimum 
distributions of the partners’ equity amounts are required to be made on a quarterly basis beginning in the first quarter 
of 2015 and will continue through January 2017.  The partnership agreement expires December 31, 2016.  We own 
directly approximately one-half of the remaining ore reserves at the Empire mine and lease them to Empire.  A subsidiary 
of ours leases the balance of the Empire reserves from other owners of such reserves and subleases them to Empire.  
Operations consist of an open pit truck and shovel mine, a concentrator that utilizes single stage crushing, AG mills, 
magnetic separation and floatation to produce a magnetite concentrate that is then supplied to the on-site pellet plant.

Tilden Mine

The Tilden mine is located on the Marquette Iron Range in Michigan’s Upper Peninsula approximately five miles 
south of Ishpeming, Michigan.  Over the past five years, the Tilden mine has produced between 7.5 million and 7.8 million 
tons of iron ore pellets annually.  We own 85 percent of Tilden, with the remaining minority interest owned by a subsidiary 
of U.S. Steel.  Each partner takes its share of production pro rata; however, provisions in the partnership agreement 
allow additional or reduced production to be delivered under certain circumstances.  We own all of the ore reserves at 
the Tilden mine and lease them to Tilden.  Operations consist of an open pit truck and shovel mine, a concentrator that 
utilizes  single  stage  crushing,  AG  mills,  magnetite  separation  and  floatation  to  produce  hematite  and  magnetic 
concentrates that are then supplied to the on-site pellet plant.

The Empire and Tilden mines are located adjacent to each other.  The logistical benefits include a consolidated 
transportation system, more efficient employee and equipment operating schedules, reduction in redundant facilities and 
workforce and best practices sharing.  Two railroads, one of which is wholly owned by us, link the Empire and Tilden

mines with Lake Michigan at the loading port of Escanaba, Michigan, and with the Lake Superior loading port of Marquette, 
Michigan.

Hibbing Mine

The Hibbing mine is located in the center of Minnesota’s Mesabi Iron Range and is approximately ten miles north 
of Hibbing, Minnesota and five miles west of Chisholm, Minnesota.  Over the past five years, the Hibbing mine has 
produced between 7.7 million and 8.1 million tons of iron ore pellets annually.  We own 23 percent of Hibbing, a subsidiary 
of ArcelorMittal has a 62.3 percent interest and a subsidiary of U.S. Steel has a 14.7 percent interest.  Each partner takes 
its share of production pro rata; however, provisions in the joint venture agreement allow additional or reduced production 
to be delivered under certain circumstances.  Mining is conducted on multiple mineral leases having varying expiration 
dates.  Mining leases routinely are renegotiated and renewed as they approach their respective expiration dates.  Hibbing 
operations consist of an open pit truck and shovel mine, a concentrator that utilizes single stage crushing, AG mills and 
magnetic separation to produce a magnetite concentrate, which is then delivered to an on-site pellet plant.  From the 
site, pellets are transported by BNSF rail to a ship loading port at Superior, Wisconsin, operated by BNSF.

Northshore Mine

The Northshore mine is located in northeastern Minnesota, approximately two miles south of Babbitt, Minnesota, 
on the northeastern end of the Mesabi Iron Range.  Northshore’s processing facilities are located in Silver Bay, Minnesota, 
near Lake Superior.  Crude ore is shipped by a wholly owned railroad from the mine to the processing and dock facilities 
at Silver Bay.  Over the past five years, the Northshore mine has produced between 3.9 million and 5.8 million tons of 
iron ore pellets annually.  One of the four furnaces in the Northshore pellet plant was idled in January 2015.  We ran a 
three furnace operation throughout 2015 until the complete idle of Northshore mine in late November 2015.  The temporary 
idle is a result of historic levels of steel imports into the U.S. and reduced demand from our steel-producing customers.  
Northshore mine is expected to be idled at least through the first quarter of 2016.

The Northshore mine began production under our management and ownership on October 1, 1994.  We own 
100 percent of the mine.  Mining is conducted on multiple mineral leases having varying expiration dates.  Mining leases 
routinely are renegotiated and renewed as they approach their respective expiration dates.  Northshore operations consist 
of an open pit truck and shovel mine where two stages of crushing occur before the ore is transported along a wholly 
owned 47-mile rail line to the plant site in Silver Bay.  At the plant site, two additional stages of crushing occur before the 
ore is sent to the concentrator.  The concentrator utilizes rod mills and magnetic separation to produce a magnetite 
concentrate, which is delivered to the pellet plant located on-site.  The plant site has its own ship loading port located 
on Lake Superior.

United Taconite Mine

The  United  Taconite  mine  is  located  on  Minnesota’s  Mesabi  Iron  Range  in  and  around  the  city  of  Eveleth, 
Minnesota.  The United Taconite concentrator and pelletizing facilities are located ten miles south of the mine, near the 
town of Forbes, Minnesota.  Over the past five years, the United Taconite mine has produced between 3.1 million and 
5.4 million tons of iron ore pellets annually.  Currently, United Taconite mine is temporarily idled. The temporary idle 
began the first week of August 2015 and is a result of historic levels of steel imports into the U.S. and reduced demand 
from our steel-producing customers. United Taconite mine is expected to be idled at least through the first quarter of 
2016.

We own 100 percent of the United Taconite mine.  Mining is conducted on multiple mineral leases having varying 
expiration dates.  Mining leases routinely are renegotiated and renewed as they approach their respective expiration 
dates.  United Taconite operations consist of an open pit truck and shovel mine where two stages of crushing occur 
before the ore is transported by rail to the plant site located ten miles to the south.  At the plant site an additional stage 
of crushing occurs before the ore is sent to the concentrator.  The concentrator utilizes rod mills and magnetic separation 
to produce a magnetite concentrate, which is delivered to the pellet plant.  From the site, pellets are transported by CN 
rail to a ship loading port at Duluth, Minnesota, operated by CN.

Asia Pacific Iron Ore

The following map shows the location of our Asia Pacific Iron Ore operation as of December 31, 2015:

In Australia, we own and operate the Koolyanobbing operations.  We produced 11.7 million metric tons, 11.4 

million metric tons and 11.1 million metric tons in 2015, 2014 and 2013, respectively.

The mineralization at the Koolyanobbing operations is predominantly hematite and goethite replacements in 
greenstone-hosted  banded  iron  formations.    Individual  deposits  tend  to  be  small  with  complex  ore-waste  contact 
relationships.  The reserves at the Koolyanobbing operations are derived from 10 separate mineral deposits distributed 
over a 70 mile operating radius.

Koolyanobbing 

The Koolyanobbing operations are located 250 miles east of Perth and approximately 30 miles northeast of the 
town of Southern Cross.  Koolyanobbing produces lump and fines iron ore.  Mining is conducted on multiple mineral 
leases having varying expiration dates.  Mining leases routinely are renewed as they approach their respective expiration 
dates.  In 2011, a significant permitting milestone was achieved with the granting of regulatory approvals necessary to 
develop above the water table at Windarling's W1 deposit.  In 2013, environmental approvals were obtained for deepening 
of the Windarling W1 pit and deepening of the Koolyanobbing A/B/C pits.  The operations at Windarling have been idled 
since the beginning of the fourth quarter of 2015 as a result of cost cutting measures.

Over the past five years, the Koolyanobbing operation has produced between 8.2 million and 11.7 million metric 
tons annually.  The expansion project at Koolyanobbing increasing annual capacity to 11 million metric tons was completed 
in 2012.  Ore material can be sourced from nine separate open pit mines and is delivered by typical production trucks 
or  road  trains  to  a  crushing  and  screening  facility  located  at  Koolyanobbing.   All  of  the  ore  from  the  Koolyanobbing 
operations is transported by rail to the Port of Esperance, 360 miles to the south, for shipment to Asian customers.

North American Coal

Throughout the majority of 2015, we directly owned and operated two North American coal mining complexes 
from which we produced a total of 4.3 million tons of coal in 2015.  In the fourth quarter of 2015, we sold these two coal 
mining complexes, Pinnacle mine and Oak Grove mine, marking our exit from the coal business. The sale was completed 
on December 22, 2015.   In 2014 and 2013, we produced 7.5 million and 7.2 million tons of coal, respectively.  Prior to 
December 31, 2014, we also owned a third coal mining complex, CLCC. We no longer own CLCC as the sale of the 
CLCC assets was completed on December 31, 2014.  The production tons above include 2.5 million tons and 2.1 million 
tons of coal produced by CLCC in 2014 and 2013, respectively.  Our coal production at each mine was shipped within 
the U.S. by rail or barge.  Coal for international customers was shipped through the ports of Mobile, Alabama; Norfolk, 
Virginia; and New Orleans, Louisiana.

As of March 31, 2015, management determined that our North American Coal operating segment met the criteria 
to be classified as held for sale under ASC 205, Presentation of Financial Statements.  As such, all current year and 
historical North American Coal operating segment results are included in our financial statements and classified within 
discontinued operations.  Refer to NOTE 14 - DISCONTINUED OPERATIONS for further discussion of the North American 
Coal segment discontinued operations.

Eastern Canadian Iron Ore

We own interests in two non-operating iron ore mines in the Canadian Provinces of Québec and Newfoundland 
and Labrador from which we had been producing iron ore concentrate through December 2014 and produced iron ore 
pellets through June 2013.  We produced 6.2 million and 8.7 million metric tons of iron ore product in 2014 and 2013, 
respectively, from these two mines.  In May 2011, we acquired Consolidated Thompson along with its 75 percent interest 
in the Bloom Lake property.  In the fourth quarter of 2013, our interest in Bloom Lake increased by an aggregate of 7.8 
percent, bringing our interest to 82.8 percent in the Bloom Lake property.

As more fully described in NOTE 14 - DISCONTINUED OPERATIONS, in January 2015, we announced that 
the Bloom Lake Group commenced restructuring proceedings in Montreal, Quebec under the CCAA.  At that time, we 
had suspended Bloom Lake operations and for several months had been exploring options to sell certain of our Canadian 
assets, among other initiatives.  Effective January 27, 2015, following the CCAA filing of the Bloom Lake Group, we 
deconsolidated the Bloom Lake Group and certain other wholly-owned subsidiaries comprising substantially all of our 
Canadian  operations.   Additionally,  on  May  20,  2015,  the  Wabush  Group  commenced  restructuring  proceedings  in 
Montreal, Quebec, under the CCAA which resulted in the deconsolidation of the remaining Wabush Group entities that 
were not previously deconsolidated.  The Wabush Group was no longer generating revenues and was not able to meet 
its obligations as they came due.  As a result of this action, the CCAA protections granted to the Bloom Lake Group were 
extended to include the Wabush Group to facilitate the reorganization of each of their businesses and operations.  Financial 
results prior to the respective deconsolidations of the Bloom Lake and Wabush Groups and subsequent expenses directly 
associated  with  the  Canadian  Entities  are  included  in  our  financial  statements  and  classified  within  discontinued 
operations. 

Mineral Policy

We have a corporate policy prescribing internal control and procedures with respect to auditing and estimating 
of minerals. The procedures contained in the policy include the calculation of mineral estimates at each property by our 
engineers,  geologists  and  accountants,  as  well  as  third-party  consultants.    Management  compiles  and  reviews  the 
calculations, and once finalized, such information is used to prepare the disclosures for our annual and quarterly reports.  
The disclosures are reviewed and approved by management, including our chief executive officer and chief financial 
officer.  Additionally, the long-range mine planning and mineral estimates are reviewed annually by our Audit Committee.  
Furthermore, all changes to mineral estimates, other than those due to production, are adequately documented and 
submitted to senior operations officers for review and approval.  Finally, periodic reviews of long-range mine plans and 
mineral reserve estimates are conducted at mine staff meetings, senior management meetings and by independent 
experts.

Mineral Reserves

Reserves  are  defined  by  SEC  Industry  Standard  Guide  7  as  that  part  of  a  mineral  deposit  that  could  be 
economically and legally extracted and produced at the time of the reserve determination.  All reserves are classified as 
proven or probable and are supported by life-of-mine plans.

36

 
 
 
 
 
 
 
 
Table of Contents

Reserve estimates are based on pricing that does not exceed the three-year trailing average of benchmark prices 
for iron ore adjusted to our realized price.  For the three-year period 2013 to 2015, the average international benchmark 
price of 62 percent Fe CFR China was $96 per dry metric ton. 

We evaluate and analyze mineral reserve estimates in accordance with our mineral policy and SEC requirements.  

The table below identifies the year in which the latest reserve estimate was completed.

Iron Ore Reserves

Ore reserve estimates for our iron ore mines as of December 31, 2015 were estimated from fully designed open 
pits  developed  using  three-dimensional  modeling  techniques.   These  fully  designed  pits  incorporate  design  slopes, 
practical mining shapes and access ramps to assure the accuracy of our reserve estimates.  All of our remaining operations 
reserves have been adjusted net of 2015 production.

Legal Proceedings

Alabama Dust Litigation.  At the time of the sale of our Oak Grove mine to Seneca on December 22, 2015, three 
cases were pending in the Alabama state court system that comprise the Alabama Dust Litigation.  Generally, these 
claims were asserted by nearby homeowners alleging that dust emanating from the Concord Preparation Plant causes 
damage to their properties.  The defense and any liability relating to these lawsuits has been assumed by Seneca as 
part of the sale.  As such, we will not continue to make disclosures relating to this litigation. 

Bloom Lake Investigation.  CQIM, Bloom Lake General Partner Limited and Bloom Lake were investigated by 
Environment Canada in relation to alleged violations of Section 36(3) of the Fisheries Act that prohibits the deposit of a 

38

 
 
  
 
 
 
Table of Contents

deleterious substance in water frequented by fish or in any place where the deleterious substance may enter any such 
water and Section 40(3) of the Fisheries Act in relation to an alleged failure to comply with a direction of an inspector.  
The investigation covered several alleged incidents that occurred between April 2011 and December 2014.  The Bloom 
Lake investigation was settled on December 19, 2014, resolving all allegations and included a fine of C$1.5 million and 
a contribution to the Environmental Damages Fund of C$6.0 million. CQIM, Bloom Lake General Partner Limited and 
Bloom Lake entered into a Management Directive with Environment Canada which outlines compliance obligations to 
address these concerns going forward.

Empire NPDES Permit Enforcement.  Empire received an enforcement letter on December 22, 2015 from the 
MDEQ alleging exceedances of the selenium effluent limit in 2014 and 2015.  The letter invited Empire to resolve the 
matter via an Administrative Consent Order.  Discussions with MDEQ regarding the foregoing alleged exceedances 
have not been concluded and the resolution of these matters is uncertain at this time.  However, it is not anticipated 
that the Administrative Consent Order obligations will be material to us.

ERISA Litigation.  On May 14, 2015, a lawsuit was filed in the United States District Court for the Northern District 
of Ohio captioned Paul Saumer, individually and on behalf of all others similarly situated, v. Cliffs Natural Resources Inc. 
et  al.,  No.  1:15-CV-00954.   This  action  was  purportedly  brought  on  behalf  of  the  Northshore  and  Silver  Bay  Power 
Company Retirement Savings Plan (the "Plan") and certain participants and beneficiaries of the Plan during the class 
period, defined in the complaint as April 2, 2012 to the present, against Cliffs Natural Resources Inc., its investment 
committee, Northshore, the Employee Benefits Administration Department of Northshore, and certain current and former 
officers.  Plaintiff amended the complaint to name as defendants additional current and former employees who served 
on the investment committee. The suit alleges that the defendants breached their duties to the plaintiffs and the Plan in 
violation of ERISA fiduciary rules by, among other things, continuing to offer and hold Cliffs Natural Resources Inc. stock 
as a Plan investment option during the class period.  The relief sought includes a request for a judgment ordering the 
defendants to make good to the Plan all losses to the Plan resulting from the alleged breaches of fiduciary duties.  The 
lawsuit has been referred to our insurance carriers.  On December 16, 2015, defendants filed a motion to dismiss the 
lawsuit.

Essar Litigation.  On January 12, 2015, The Cleveland-Cliffs Iron Company, Northshore Mining Company and 
Cliffs Mining Company (collectively, the "Cliffs Plaintiffs") filed a complaint against Essar in the U.S. District Court for the 
Northern District of Ohio, Eastern Division, asserting that Essar breached the parties' Pellet Sale and Purchase Agreement, 
as amended (the "Pellet Agreement") by, among other things, failing to take delivery of and pay for its nominated ore in 
2014, failing to make certain payments under a true up provision, and disclosing confidential information.  The complaint 
also  seeks  a  declaration  that  Essar  is  not  entitled  to  receive  certain  credit  payments  under  the  terms  of  the  Pellet 
Agreement.  The Cliffs Plaintiffs seek damages in excess of $90 million.  Essar filed an Answer and Counterclaim on 
February 11, 2015, seeking damages in excess of $160 million for various alleged breaches of the Pellet Agreement, 
including failure to deliver ore, overcharging for certain deliveries, failure to pay certain credit payments and disclosing 
confidential information. The parties started the discovery process, with a discovery cutoff date set for October 30, 2015, 
and a trial date set for December 7, 2015.  The parties agreed to attempt mediation of the claims.  Two mediation sessions 
took place on March 7 and April 21, 2015. The mediations were unsuccessful.  The Cliffs Plaintiffs filed a Motion for 
Partial Summary Judgment on July 31, 2015, which was granted in part on October 8, 2015.  With respect to the Cliffs 
Plaintiffs' claim that Essar had breached by failing to take its 2014 nomination, the Court found that Essar had breached 
and had failed to take between 500,000 and 700,000 tons of its 2014 nomination.  The summary judgment ruling also 
dismissed Essar’s counterclaim that the Cliffs Plaintiffs had overcharged Essar by improperly measuring moisture levels.  
With respect to this claim, the Court found that there was "no basis" for Essar's claim that the Cliffs Plaintiffs had breached 
the contract.  On October 5, 2015, the Cliffs Plaintiffs terminated the Pellet Agreement because of Essar’s continual 
breach of the Pellet Agreement.  On October 6, 2015, Essar filed motions for temporary restraining order and preliminary 
injunction.  Essar withdrew both motions on October 15, 2015, before any order was entered on either motion.  

On November 9, 2015, Essar filed for protection under CCAA in Canada in the Ontario Superior Court of Justice 
and Chapter 15 bankruptcy protection in the United States in the U.S. District Court for the District of Delaware.  As a 
result of the stay related to Essar's bankruptcy proceedings, the litigation in U.S. District Court for the Northern District 
of Ohio was dismissed without prejudice stating that either party could reinstate the case upon application, if necessary, 
when the bankruptcy proceedings have concluded.  Essar moved the CCAA Court to determine that the Cliffs Plaintiffs' 
termination of the Pellet Agreement was invalid and to reinstate the Pellet Agreement.  The Cliffs Plaintiffs have objected 
based upon inappropriate jurisdiction and other grounds.  On January 25, 2016, the CCAA Court determined that it has 
proper jurisdiction and instructed the parties to determine an appropriate procedure to try the facts in front of the CCAA 
Court.  The Cliffs Plaintiffs filed an appeal of the CCAA Court's decision regarding proper jurisdiction on February 8, 
2016.

Michigan Electricity Matters.  On February 19, 2015, in connection with various proceedings before FERC with 
respect to certain cost allocations for continued operation of the Presque Isle Power Plant in Marquette, Michigan, FERC 
issued an order directing MISO to submit a revised methodology for allocating SSR costs that identified the load serving 
entities that require the operation of SSR units at the power plant for reliability purposes.  On September 17, 2015, FERC 
issued an order conditionally approving MISO’s revised allocation methodology.  Parties have filed petitions for rehearing 
on FERC's order as well as protests against MISO's compliance filing submitted pursuant to the order.  FERC has deferred 
its decision on the issue of retroactive refunds until after it has approved MISO’s allocation methodology in full.  Should 
FERC award SSR costs based on the revised cost allocation methodology applied retroactively, our current estimate of 
the potential liability to our Empire and Tilden mines is approximately $17.1 million.  We, however, continue to challenge 
the imposition of any SSR costs before FERC and the U.S. Court of Appeals for the D.C. Circuit.

Pinnacle Mine Environmental Litigation.  On June 22, 2010, the West Virginia DEP filed a lawsuit in the Wyoming 
County Circuit Court against the Pinnacle mine alleging past non-compliance with its NPDES discharge permit.  The 
complaint seeks injunctive relief and penalties.  An initial penalty proposal of $1.0 million was offered by the West Virginia 
DEP in March 2012; however, Pinnacle disagrees with the alleged violations and has met with the DEP to present facts 
supporting a review and reduction of the proposed penalty.  The defense and any liability relating to this lawsuit have 
been assumed by Seneca as part of the sale.  As such, we will not continue to make disclosures relating to this litigation.

Pointe  Noire  Investigation.   Wabush  Mines  was  investigated  by  Environment  Canada  in  relation  to  alleged 
violations of (i) Section 36(3) of the Fisheries Act, which prohibits the deposit of a deleterious substance in water frequented 
by fish or in any place where the deleterious substance may enter any such water, and (ii) Section 5.1 of the Migratory 
Bird Convention Act, 1994.  The Québec Ministry of Sustainable Development, Environment, Wildlife and Parks also 
conducted an investigation into alleged violations of Section 8 of the Hazardous Material Regulation, which prohibits the 
discharge of a hazardous material to the environment.  The investigations covered events surrounding and leading up 
to the alleged release of approximately 1,320 gallons of fuel oil into the Bay of Sept-Iles on September 1, 2013.  We 
cooperated with the investigators and agency response officials.  In April 2014, the Québec Ministry of Justice filed a 
penalty charge related to the incident.  The Pointe Noire investigation was settled in December 2014.  A fine of C$750,000 
and C$61,000 in costs were paid.  We are anticipating a report by the Québec Ministry related to their assessment of 
the  cleanup  activities  performed  by  Wabush  Mines  and  further  direction  related  to  requirements  for  additional 
environmental monitoring, if any.

Putative Class Action Lawsuits.  In May 2014, alleged purchasers of our common shares filed suit in the U.S. 
District Court for the Northern District of Ohio against us and certain former officers and directors of the Company.  The 
action is captioned Department of the Treasury of the State of New Jersey and Its Division of Investment v. Cliffs Natural 
Resources Inc., et al., No. 1:14-CV-1031.  As amended, the action asserts violations of the federal securities laws based 
on alleged false or misleading statements or omissions during the period of March 14, 2012 to March 26, 2013, regarding 
operations at our Bloom Lake mine in Québec, Canada, and the impact of those operations on our finances and outlook, 
including  sustainability  of  the  dividend,  and  that  the  alleged  misstatements  caused  our  common  shares  to  trade  at 
artificially inflated prices.  The parties have successfully mediated this dispute and reached a settlement in principle, 
subject to definitive documentation, shareholder notice and court approval.  The lawsuit had been referred to our insurance 
carriers, who will be required to pay the entirety of the $84 million settlement amount, if approved by the court.  The court 
is expected to schedule a settlement approval hearing.  The settlement of this lawsuit, if approved, will have no impact 
on our financial position or operations.

In June 2014, an alleged purchaser of the depositary shares issued by Cliffs in a public offering in February 2013 
filed a putative class action, which is captioned Rosenberg v. Cliffs Natural Resources Inc., et al., and after a round of 
removal and remand motions, is now pending in the Cuyahoga County , Ohio, Court of Common Pleas, No. CV-14-828140. 
As amended, the suit asserts claims against us, certain current and former officers and directors of the Company, and 
several underwriters of the offering, alleging disclosure violations in the offering documents regarding operations at our 
Bloom Lake mine, the impact of those operations on our finances and outlook, and about the progress of our former 
exploratory chromite project in Ontario, Canada. The parties successfully mediated this dispute and reached a settlement 
agreement in principle, subject to definitive documentation, notice to class members and court approval.  The settlement 
provides for a payment to the proposed class of $10 million, which has been deposited into escrow by the insurance 
carriers.  A court hearing, during which the parties will seek court approval of the proposed class action settlement, is 
scheduled for April 14, 2016.

Shareholder Derivative Lawsuits. In June and July 2014, alleged shareholders of Cliffs filed three derivative 
actions in the Cuyahoga County, Ohio, Court of Common Pleas asserting claims against certain current and former 
officers and directors of the Company.  These actions, captioned Black v. Carrabba, et al., No. CV-14-827803, Asmussen 
v. Carrabba, et al., No. CV-14-829259, and Williams, et al. v. Carrabba, et al., No. CV-14-829499, allege that the individually 
named  defendants  violated  their  fiduciary  duties  to  the  Company  by,  among  other  things,  disseminating  false  and

misleading  information  regarding  operations  at  our  Bloom  Lake  mine  in  Québec,  Canada,  and  the  impact  of  those 
operations on our finances and outlook, including sustainability of the dividend, failing to maintain internal controls, and 
failing to appropriately oversee and manage the Company.  The complaints assert additional claims for unjust enrichment, 
abuse of control, gross mismanagement, overpayment upon departure of certain executives, and waste of corporate 
assets. The parties have reached a settlement in principle to settle all three cases, subject to definitive documentation, 
shareholder notice and court approval.  Under the pending settlement, the Company will agree to enact or continue 
various corporate-governance related measures and to pay plaintiffs' attorneys' fees and expenses. The lawsuit had 
been referred to our insurance carriers who will pay $775,000 for attorneys' fees and expenses to plaintiffs' lawyers.  The 
settlement of these actions will have no impact on our financial position.  Following the announcement of the settlement 
in principle of these three shareholder derivative cases, an additional derivative shareholder action, captioned Mansour 
v. Carrabba, et al., No. 16-CV-00390, was filed in the U.S. District Court for the Northern District of Ohio against the 
same defendants and alleging substantially identical claims. This additional lawsuit has been referred to our insurance 
carriers.

The Rio Tinto Mine Site.  The Rio Tinto Mine Site is an historic underground copper mine located near Mountain 
City, Nevada, where tailings were placed in Mill Creek, a tributary to the Owyhee River.  Site investigation and remediation 
work is being conducted in accordance with a Consent Order dated September 14, 2001, between the Nevada DEP and 
the RTWG composed of the Company, Atlantic Richfield Company, Teck Cominco American Incorporated and E. I. duPont 
de Nemours and Company.  The Consent Order provides for technical review by the U.S. Department of the Interior 
Bureau of Indian Affairs, the U.S. Fish and Wildlife Service, U.S. Department of Agriculture Forest Service, the Nevada 
DEP and the Shoshone-Paiute Tribe of the Duck Valley Reservation (collectively, the "Rio Tinto Trustees").  In recognition 
of  the  potential  for  an  NRD  claim,  the  parties  actively  pursued  a  global  settlement  that  would  include  the  EPA  and 
encompass both the remedial action and the NRD issues.

The Nevada DEP published a Record of Decision for the Rio Tinto Mine, which was signed on February 14, 
2012, by the Nevada DEP and the EPA.  On September 27, 2012, the agencies subsequently issued a proposed Consent 
Decree, which was lodged with the U.S. District Court for the District of Nevada and was finalized on May 20, 2013.  
Under the terms of the Consent Decree, the RTWG has agreed to pay over $29 million in cleanup costs and natural 
resource damages to the site and surrounding area.  Under the terms of the Consent Decree, the RTWG is responsible 
for removing mine tailings from Mill Creek, improving the creek to support redband trout, improving water quality in Mill 
Creek and the East Fork Owyhee River and long term monitoring of the site.  Nevada DEP will oversee the cleanup, with 
input from EPA and monitoring from the Rio Tinto Trustees. The Company's share of the total settlement cost, which 
includes this remedial action, insurance and other oversight costs, was $12.2 million.  As of December 31, 2015, we had 
completed all required payments related to the Consent Decree.

Southern Natural Gas Lawsuit.  On July 23, 2014, Southern Natural Gas Company, L.L.C. filed a lawsuit in the 
Circuit Court of Jefferson County, Alabama (Case No. 68-CV-2014-900533.00) against the Company and others.  The 
suit seeks to prevent coal mining activity underneath a gas pipeline at our Oak Grove property and to require defendants 
to pay the costs associated with relocating that pipeline.  The suit asserts claims for declaratory judgment and nuisance.  
This lawsuit was pending at the time of the sale of our Oak Grove mine to Seneca.  The defense and any liability relating 
to this lawsuit has been assumed by Seneca as part of the sale, including the obligation to indemnify the Company as 
a named defendant.  As such, we will not continue to make disclosures relating to this litigation.

Taconite MACT Compliance Review.  EPA Region 5 issued Notices of Violation during the first quarter of 2014 
to  Empire, Tilden  and  United Taconite  related  to  alleged  historical  violations  of  the Taconite  MACT  rule  and  certain 
elements of the respective state-issued Title V operating permits. While the matter has been referred to the DOJ for 
enforcement, it is not anticipated currently to have a material impact on our business.

Worldlink Arbitration.  In October 2011, our wholly owned subsidiary, CQIM, along with Bloom Lake General 
Partner Limited and The Bloom Lake Iron Ore Mine Limited Partnership, instituted an arbitration claim against the Bloom 
Lake mine’s former customer, Worldlink Resources Limited, for material and/or fundamental breaches of the parties’ 
2007 offtake agreement for the purchase and sale of iron concentrate produced at the Bloom Lake mine.  Our subsidiaries 
filed the arbitration claim with the International Court of Arbitration of the International Chamber of Commerce pursuant 
to the dispute resolution provisions of the offtake agreement.  Our subsidiaries terminated the offtake agreement with 
Worldlink in August 2011 due to Worldlink’s failure to fulfill its obligations under the agreement and Worldlink’s demand 
to renegotiate the price of the iron ore concentrate in spite of being party to a long-term offtake agreement.  Our subsidiaries 
claimed damages for the breach of the offtake agreement in excess of $85 million and Worldlink counterclaimed for 
damages in excess of $100 million.  In November 2014, the arbitrators decided in favor of Worldlink and awarded it 
damages in an amount of approximately $71 million as well as approximately $25 million in accrued interest from the 
date of termination of the offtake agreement in August 2011 and arbitration costs. This judgment has been included in 
the CCAA filing of the Bloom Lake Group and will be treated as an unsecured claim.

Mine Safety Disclosures

We are committed to protecting the occupational health and well-being of each of our employees.  Safety is one 
of our core values, and we strive to ensure that safe production is the first priority for all employees.  Our internal objective 
is to achieve zero injuries and incidents across the Company by focusing on proactively identifying needed prevention 
activities,  establishing  standards  and  evaluating  performance  to  mitigate  any  potential  loss  to  people,  equipment, 
production and the environment.  We have implemented intensive employee training that is geared toward maintaining 
a high level of awareness and knowledge of safety and health issues in the work environment through the development 
and coordination of requisite information, skills and attitudes.  We believe that through these policies, we have developed 
an effective safety management system.

Under the Dodd-Frank Act, each operator of a coal or other mine is required to include certain mine safety results 
within its periodic reports filed with the SEC.  As required by the reporting requirements included in §1503(a) of the Dodd-
Frank Act and Item 104 of Regulation S-K, the required mine safety results regarding certain mining safety and health 
matters for each of our mine locations that are covered under the scope of the Dodd-Frank Act are included in Exhibit 
95 of Item 15. Exhibits and Financial Statement Schedules of this Annual Report on Form 10-K.

*   Management determined as of March 31, 2015, that our North American Coal operating segment met the criteria to be classified as held for sale 
under ASC 205, Presentation of Financial Statements.  The North American Coal segment continued to meet the criteria throughout 2015 until 
we sold our North American Coal operations during the fourth quarter of 2015.  As such, all current and historical North American Coal operating 
segment results are included in our financial statements and classified within discontinued operations. 
On January 27, 2015, we announced that the Bloom Lake Group commenced restructuring proceedings (the "Bloom Filing") under the CCAA with 
the Québec Superior Court (Commercial Division) in Montreal (the “Court”).  At that time, the Bloom Lake Group was no longer generating revenues 
and was not able to meet its obligations as they came due.  The Bloom Filing addressed the Bloom Lake Group's immediate liquidity issues and 
permits the Bloom Lake Group to preserve and protect its assets for the benefit of all stakeholders while restructuring and sale options are explored.  
As part of the CCAA process, the Court approved the appointment of a Monitor and certain other financial advisors.  Additionally, on May 20, 2015, 
we announced that the Wabush Group commenced restructuring proceedings (the "Wabush Filing") in the Court under the CCAA.  As a result of 
this action, the CCAA protections granted to the Bloom Lake Group were extended to include the Wabush Group to facilitate the reorganization 
of each of their businesses and operations.  The Wabush Group was no longer generating revenues and was not able to meet its obligations as 
they came due.  The inclusion of the Wabush Group in the existing Bloom Filing will facilitate a more comprehensive restructuring and sale process 
of both the Bloom Lake Group and the Wabush Group which collectively include mine, port and rail assets and will lead to a more effective and 
streamlined exit from Eastern Canada.  The Wabush Filing will also mitigate various legacy related long-term liabilities associated with the Wabush 
Group.  As part of the Wabush Filing, the Court approved the appointment of a Monitor and certain other financial advisors.  The Monitor of the 
Wabush Group is also the Monitor of the Bloom Lake Group.  Financial results prior to the respective deconsolidations of the Bloom Lake and 
Wabush Groups and subsequent expenses directly associated with the Canadian Entities are included in our financial statements and classified 
within discontinued operations. 
On July 10, 2012, we entered into a definitive share and asset sale agreement to sell our 45 percent economic interest in the Sonoma joint venture 
coal mine located in Queensland, Australia.  Additionally, on September 27, 2011, we announced our plans to cease and dispose of the operations 
at the renewaFUEL biomass production facility in Michigan.  On January 4, 2012, we entered into an agreement to sell the renewaFUEL assets 
to  RNFL Acquisition  LLC.   The  results  of  operations  of  the  Sonoma  joint  venture  and  renewaFUEL  operations  are  reflected  as  discontinued 
operations in the accompanying consolidated financial statements for all periods presented.

(a) During 2011 we paid quarterly common share dividends of $0.14 per share.  The increased 2011 cash dividends were paid on March 1, 2011, 
and June 1, 2011, to shareholders on record as of February 15, 2011, and April 29, 2011, respectively.  On July 12, 2011, our Board of Directors 
increased the quarterly common share dividend by 100 percent to $0.28 per share.  The increased cash dividend was paid on September 1, 
2011, December 1, 2011, and March 1, 2012, to our shareholders on record as of the close of business on August 15, 2011, November 18, 2011, 
and February 15, 2012, respectively.  On March 13, 2012, our Board of Directors increased the quarterly common share dividend by 123 percent 
to $0.625 per share.  The increased cash dividend was paid on June 1, 2012, August 31, 2012 and December 3, 2012 to our shareholders on 
record as of April 27, 2012, August 15, 2012, and November 23, 2012, respectively. On February 11, 2013, our Board of Directors approved a 
reduction to our quarterly cash dividend rate by 76 percent to $0.15 per share.  The decreased dividend of $0.15 per share was paid on March 1, 
2013, June 3, 2013, September 3, 2013, and December 2, 2013 to our common shareholders of record as of the close of business on February 
22, 2013, May 17, 2013, August 15, 2013, and November 22, 2013, respectively.  Additionally, in 2014, the dividend of $0.15 per share was paid 
on March 3, 2014, June 3, 2014, September 2, 2014 and December 1, 2014 to our common shareholders of record as of the close of business 
on February 21, 2014, May 23, 2014, August 15, 2014, and November 15, 2014, respectively.  On January 26, 2015, we announced that our 
Board of Directors had decided to eliminate the quarterly dividend of $0.15 per share on our common shares.  The decision was applicable to 
the first quarter of 2015 and all subsequent quarters.  The elimination of the common share dividend provides us with additional free cash flow 
of approximately $92 million annually, which we intend to use for further debt reduction. 

(b)  On May 12, 2011, we completed our acquisition of Consolidated Thompson by acquiring all of the outstanding common shares of Consolidated 
Thompson for C$17.25 per share in an all-cash transaction including total debt less cash. Consolidated Thompson was included within the entities 
under the CCAA filing. As noted above, financial results prior to the respective deconsolidations of the Bloom Lake and Wabush Groups and 
subsequent expenses directly associated with the Canadian Entities are included in our financial statements and classified within discontinued 
operations. 

      In 2011, during our annual goodwill impairment test in the fourth quarter, a goodwill impairment charge of $27.8 million was recorded for our 
CLCC reporting unit, within the North American Coal operating segment.  As noted above, all current and historical North American Coal operating 
segment results are included in our financial statements and classified within discontinued operations. 

(c)  Upon performing our annual goodwill impairment test in the fourth quarter of 2012, goodwill impairment charges of $997.3 million and $2.7 million 
were recorded for our CQIM and Wabush reporting units, respectively, both within the Eastern Canadian Iron Ore operating segment.  We also 
recorded an impairment charge of $49.9 million related to our Eastern Canadian Iron Ore operations to reduce those assets to their estimated 
fair value as of December 31, 2012, due to the idling of the pelletizing facility at Pointe Noire.  All of these charges impacted Other operating 
expense. The Eastern Canadian Iron Ore operations were included within the entities under the CCAA filing. As noted above, financial results 
prior to the respective deconsolidations of the Bloom Lake and Wabush Groups and subsequent expenses directly associated with the Canadian 
Entities are included in our financial statements and classified within discontinued operations.

       As a result of the approval for the sale of our 30 percent interest in Amapá, an impairment charge of $365.4 million was recorded through Equity 

income (loss) from ventures for the year ended December 31, 2012.

(d)  On March 20, 2013, our Board of Directors declared a cash dividend of $13.6111 per preferred share, which is equivalent to approximately $0.34 
per depositary share.  The cash dividend was paid on May 1, 2013, to our preferred shareholders of record as of the close of business on April 15, 
2013.  On May 7, 2013, September 9, 2013, and November 11, 2013, our Board of Directors declared a quarterly cash dividend of $17.50 per 
preferred share, which is equivalent to approximately $0.44 per depositary share.  The cash dividends were paid on August 1, 2013, November 
1, 2013, and February 3, 2014 to our preferred shareholders of record as of the close of business on July 15, 2013, October 15, 2013, and 
January 15, 2014, respectively.   The cash dividend was paid on May 1, 2013 to our preferred shareholders of record as of the close of business 
on April 15, 2013.  On February 11, 2014, May 13, 2014, September 8, 2014, and November 19, 2014, our Board of Directors declared a quarterly 
cash dividend of $17.50 per preferred share, which is equivalent to approximately $0.44 per depositary share.  The cash dividends were paid 
on May 1, 2014, August 1, 2014, November 3, 2014, and February 2, 2015, to our preferred shareholders of record as of the close of business 
on April 15, 2014, July 15, 2014, October 15, 2014, and January 15, 2015, respectively. On March 27, 2015, July 1, 2015, and September 10, 
2015, our Board of Directors declared the quarterly cash dividend of $17.50 per Preferred Share, which is equivalent to approximately $0.44 per 
depositary share.  The cash dividend was paid on May 1, 2015, August 3, 2015, and November 2, 2015 to our shareholders of record as of the 
close of business on April 15, 2015, July 15, 2015, and October 15, 2015, respectively.

(e)  Upon performing our annual goodwill impairment test in the fourth quarter of 2013, a goodwill impairment charge of $80.9 million was recorded 
for our Cliffs Chromite Ontario and Cliffs Chromite Far North reporting units within our Ferroalloys operating segment.  We also recorded other 
long-lived asset impairment charges of $169.9 million, of which $154.6 million relates to our Wabush reporting unit within our Eastern Canadian 
Iron Ore operating segment to reduce those assets to their estimated fair value as of December 31, 2013.  These reporting units were included 
within the entities under the CCAA filing. As noted above, financial results prior to the respective deconsolidations of the Bloom Lake and Wabush 
Groups and subsequent expenses directly associated with the Canadian Entities are included in our financial statements and classified within 
discontinued operations.

(f)   During 2014, we recorded an impairment of goodwill and other long-lived assets of $73.5 million. The goodwill impairment charge of $73.5 million 
related to our Asia Pacific Iron Ore reporting unit. There were also other long-lived asset impairment charges of $562.0 million related to our 
continuing operations including the Asia Pacific Iron Ore operating segment and our Other reportable segments. The other long-lived asset 
impairment charges which related to our discontinued operations were $8,394.4 million related to our Wabush operation and Bloom Lake operation 
within our Eastern Canadian Iron Ore operating segment, and our CLCC thermal operation, Oak Grove operation and Pinnacle operation within 
our  North American  Coal  operating  segment,  along  with  impairments  charged  to  reporting  units  within  our  Other  reportable  segments. The 
impairment charges were primarily a result of changes in life-of-mine cash flows due to declining pricing for both global iron ore and low-volatile 
metallurgical coal, which impacts our estimate of long-term pricing, along with changes in strategic focus including exploratory phases of possible 
divestiture of the operations as the new Chief Operating Decision Maker views Eastern Canadian Iron Ore, Asia Pacific Iron Ore, North American 
Coal and Ferroalloys as non-core assets.  The CLCC assets were sold in the fourth quarter of 2014 on December 31, 2014, resulting in a loss 
on sale of $419.6 million. As noted above, all current and historical North American Coal operating segment results are included in our financial 
statement and classified within discontinued operations. 

(g) On January 27, 2015, we announced that the Bloom Lake Group commenced restructuring proceedings (the "Bloom Filing") under the CCAA 
with the Québec Superior Court (Commercial Division) in Montreal (the “Court”).  Additionally, on May 20, 2015, we announced that the Wabush 
Group commenced restructuring proceedings (the "Wabush Filing") in the Court under the CCAA.  As a result of this action, the CCAA protections 
granted to the Bloom Lake Group were extended to include the Wabush Group to facilitate the reorganization of each of their businesses and 
operations. 
Consistent with our strategy to extract maximum value from our current assets, on December 22, 2015, we sold our equity interests in all the 
remaining North American Coal operations to Seneca Coal Resources, LLC ("Seneca").  The sale included Pinnacle mine in West Virginia and 
Oak Grove mine in Alabama.  Additionally, Seneca may pay Cliffs an earn-out of up to $50 million contingent upon the terms of a revenue sharing 
agreement which extends through the year 2020.   As noted above, all current and historical North American Coal operating segment results are 
included in our financial statement and classified within discontinued operations.

Management's Discussion and Analysis of Financial Condition and Results of Operations

Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") is designed 
to provide a reader of our financial statements with a narrative from the perspective of management on our financial 
condition, results of operations, liquidity and other factors that may affect our future results.  The following discussion 
should be read in conjunction with the Consolidated Financial Statements and related notes that appear elsewhere in 
this document.

Industry Overview

The key driver of our business is demand for steelmaking raw materials from U.S. steelmakers.  In 2015, the 
U.S. produced approximately 79 million metric tons of crude steel or about 5 percent of total global crude steel production.  
This represents an approximate 10 percent decrease in U.S. crude steel production when compared to 2014.  U.S. total 
steel capacity utilization was approximately 71 percent in 2015, which is an approximate 7 percent decrease from 2014.  
Additionally, in 2015, China produced approximately 804 million metric tons of crude steel, or approximately 50 percent 
of total global crude steel production.  These figures represent an approximate 2 percent decrease in Chinese crude 
steel production when compared to 2014.  Throughout 2015, global crude steel production decreased about 3 percent 
compared to 2014.

Throughout 2015, the Platts 62 percent Fe fines spot price has been driven down by a combination of reduced 
domestic steel demand from China and increased global iron ore production leading to excess supply, as well as mining 
cost deflation and a sharp fall in Australian and Brazilian currencies versus the U.S. dollar.  In 2016, we do not expect 
to see meaningful improvement in iron ore prices without significant changes to the global iron ore supply-demand picture.

The iron ore supply-demand situation has not only adversely impacted iron ore producers, but also the global 
steel industry. Currently, the global steel industry is experiencing its worst conditions in over a decade, with prices for 
products falling even lower than those realized during the most recent recession - the 2008 global financial crisis. We 
believe that very low cost iron ore has contributed substantially to foreign steel exported out of China and other countries 
into the U.S. market.  As a result of these imports, as well as the continued weakening of the oil and gas sector, domestic 
pricing for steel has been depressed and in turn, our customers' demand for pellets has fallen.  In 2016, we expect these 
conditions to improve as recently imposed duties on unfairly traded steel should curb the steel imports entering the U.S, 
and as a result we expect to see domestic steel pricing rising throughout 2016.

The Platts 62 percent Fe fines spot price decreased 37 percent to an average price of $47 per ton for the three 
months ended December 31, 2015 compared to the respective quarter of 2014.  In comparison, the year to date Platts 
62 percent Fe fines spot pricing has decreased 43 percent to an average price of $56 per ton during the year ended 
December 31, 2015.  These large decreases in the Platts 62 percent Fe fines spot price were driven by insufficient growth 
in Chinese demand to absorb the additional seaborne supply.  The spot price volatility impacts our realized revenue 
rates, particularly in our Asia Pacific Iron Ore business segment because its contracts correlate heavily to world market 
spot pricing and to a lesser extent certain of our U.S. Iron Ore contracts. 

As a result of our long-term contracts, for the three months and year ended December 31, 2015 when compared 
to the comparable prior year, our U.S. Iron Ore revenues experienced a realized revenue rate decrease of 25 percent 
and 23 percent, respectively, versus the much higher decreases in Platts 62 percent Fe fines spot price.  Additionally, 
the first quarter sales tons for U.S. Iron Ore in both 2015 and 2014 include a substantial amount of carry over tonnage 
from prior year nominations which are priced based on prior year price formulas.  

Our consolidated revenues for the years ended December 31, 2015 and 2014 were $2.0 billion and $3.4 billion, 
respectively, with net income from continuing operations per diluted share of $0.63 and net loss from continuing operations 
per diluted share of $0.14, respectively.  Net income from continuing operations for the year ended December 31, 2015 
was impacted positively by a $392.9 million gain on extinguishment of debt.  This was offset by lower sales margin which 
decreased by $649.2 million for the year ended December 31, 2015 when compared to 2014 primarily driven by lower 
market pricing for our products and decreased sales volume partially offset by cost cutting measures and favorable 
foreign exchange rates.  Additionally, results for the year ended December 31, 2015 were impacted negatively by the 
increase in income tax expense of $255.3 million primarily due to the net increase in the valuation allowance on U.S. 
deferred tax assets, partially offset by the utilization of net operating losses.  Net income from continuing operations in 
2014 was impacted negatively by $562.0 million of long-lived asset impairment recorded in the second half of 2014 along 
with $73.5 million of goodwill impairment recorded in the third quarter of 2014.

Strategy 

The Company is Focused on our Core U.S. Iron Ore Business

We continue the strategic shift to a company focused fully on our U.S. Iron Ore business.  We are the market-
leading iron ore producer in the U.S., supplying differentiated iron ore pellets under long-term contracts, some of which 
begin to expire at the end of 2016, to the largest North America steel producers.  Cliffs has the unique advantage of 
being a low cost producer of iron ore pellets in the U.S. market.  Pricing structures contained in and the long-term supply 
provided by our existing contracts, along with our low-cost operating profile, positions U.S. Iron Ore as our most stable 
business.  We expect to continue to strengthen our U.S. Iron Ore operating cost profile through continuous operational 
improvements and disciplined capital allocation policies.  Strategically, we continue to develop various entry options into 
the EAF market.  As the EAF steel market continues to grow in the U.S., there is an opportunity for our iron ore to serve 
this market by providing pellets to the alternative metallics market to produce direct reduced iron pellets, hot briquetted 
iron and/or pig iron.  In 2015, we produced and shipped a batch trial of DR-grade pellets, a source of lower silica iron 
units for the production of direct reduced iron pellets.  In early 2016, we reached a significant milestone with positive 
results from the successful industrial trial of our DR-grade pellets.  While we are still in the early stages of developing 
our alternative metallic business, we believe this will open up a new opportunity for us to diversify our product mix and 
add new customers to our U.S. Iron Ore segment beyond the traditional blast furnace clientele.

Reviewing All Other Businesses for Either Optimization, Divestiture or Shutdown

We commenced restructuring proceedings for our Eastern Canadian Iron Ore businesses under the CCAA in 
the first quarter of 2015.  During the second quarter of 2015, the CCAA protection granted to the Bloom Lake Group was 
extended to include the Wabush Group to facilitate the reorganization of each of their businesses and operations.   For 
more information regarding the status of our divestiture of our Eastern Canadian Iron Ore business, see NOTE 14 - 
DISCONTINUED OPERATIONS for further information.  

On December 22, 2015, we closed the sale of our remaining North American Coal business which included 
Pinnacle mine in West Virginia and Oak Grove mine in Alabama.  The remaining North American Coal business was 
sold to Seneca Coal Resources, LLC.  The sale marked our exit from the coal business and represents another very 
important step in the implementation of our U.S. Iron Ore pellet-centric, environmentally compliant strategy.  Prior to this 
sale, it was determined by management as of March 31, 2015 that our North American Coal operating segment met the 
criteria to be classified as held for sale under ASC 205, Presentation of Financial Statements.  For more information 
regarding  the  sale  and  the  held  for  sale  classification  of  our  North  American  Coal  business,  see  NOTE  14  - 
DISCONTINUED OPERATIONS for further information.  

As an extension of our re-focused U.S. Iron Ore strategy, we continue to consider further divestiture of the Asia 
Pacific Iron Ore business.  We believe the assets from this non-core segment have value and will only consummate a 
transaction where we believe the consideration fairly and adequately represents such value.  Asia Pacific Iron Ore is a 
well-recognized and reliable supplier to steelmakers in Asia.  As we consider selling this business, we will continue to 
operate Asia Pacific Iron Ore with very low total capital expenditures for the remaining life of mine.  

Maintaining Discipline on Costs and Capital Spending and Improving our Financial Flexibility

We believe our ability to execute our strategy is dependent on our financial position, balance sheet strength and 
financial flexibility to manage through current demand for our products and volatility in commodity prices.  We have 
developed  a  highly  disciplined  financial  and  capital  expenditure  plan  with  a  focus  on  improving  our  cost  profile  and 
increasing long-term profitability.  We resized and streamlined our organization and support functions to better fit our 
new strategic direction.  Our capital allocation plan is focused on strengthening our core U.S. Iron Ore operations to 
promote greater free cash flow generation.

Competitive Strengths 

Resilient U.S. Iron Ore Operations

Our U.S. Iron Ore segment is the core focus of our business strategy.  The U.S. Iron Ore segment is the primary 
contributor to our consolidated results, generating 76 percent of consolidated revenue and $352 million of consolidated 
Adjusted EBITDA for the year ended December 31, 2015.  U.S. Iron Ore produces differentiated iron ore pellets that are 
customized for use in customers’ blast furnaces as part of the steelmaking process.  The grades of pellets currently 
delivered to each customer are based on that customer’s preferences, which depend in part on the characteristics of the 
customer’s blast furnace operation.  We believe our long history of supplying customized pellets to the U.S. steel producers 
has resulted in a co-dependent relationship between us and our customers.  This technical and operational co-dependency 

49

 
 
 
 
 
 
 
 
 
 
Table of Contents

has enabled Cliffs to claim a substantial portion of the total U.S. iron ore market.  Based on Cliffs’ equity ownership in 
its U.S. mines, Cliffs’ share of the annual rated production capacity is 25.5 million tons, representing 44 percent of total 
U.S. annual pellet capacity.  Long-lived assets with an average mine life of approximately 20 years provide the opportunity 
to maintain our significant market position well into the future.

We believe U.S. Iron Ore is uniquely positioned in the global iron ore market due to its reduced exposure to 
seaborne iron ore pricing.  More than half of U.S. Iron Ore production is sold through long-term contracts that are structured 
with various formula-based pricing mechanisms that reference seaborne pricing, inflation factors and steel prices and 
mitigate the impact of any one factor's price volatility on our business.  U.S. Iron Ore’s realized revenue rate decreased 
25 percent and 23 percent for the three months and year ended December 31, 2015, respectively, compared to a 37 
percent and 43 percent decline in the Platts 62 percent Fe fines spot price over the same periods.

In addition, we maintain lower costs compared to our competition as a result of our proximity to U.S. steelmaking 
operations.  Our costs are lower as a result of inherent transportation advantages associated with our mine locations 
near the Great Lakes which allows for transportation via railroads and loading ports.  U.S. Iron Ore mines also benefit 
from on-site pellet production and ore production facilities located a short distance from the mines. These advantages 
translated to cash production costs in the three months and year ended December 31, 2015 of $45 per ton and $54 per 
ton,  respectively,  which  included  the  cost  to  mine,  concentrate  and  pelletize,  certain  transportation  costs  and  site 
administration costs.

Competitive Asia Pacific Iron Ore Operations

Although our annual production tonnage is substantially less than our competitors in the seaborne market, the  
Asia Pacific Iron Ore business maintains a competitive position with the major Australian iron ore producers.  We produce 
a product mix of approximately 50 percent lump ore and 50 percent fines, which is a significantly higher lump mix than 
the major producers in Australia.  This lump ore commands a premium in the seaborne market over iron ore fines.

Further, our Asia Pacific Iron Ore segment is a cost competitive producer and requires minimal ongoing sustaining 
capital expenditures to continue our operations.  Cash production costs during the three months and year ended December 
31, 2015, were $26 per ton and $31 per ton, respectively.  Going forward, we will continue to operate Asia Pacific Iron 
Ore with a clear bias toward cash optimization.

Recent Developments

USW Labor Agreements

Our labor agreements with the USW at our Tilden, Empire, Hibbing and United Taconite mines were scheduled 
to expire at 12:01 a.m. on October 1, 2015.  Prior to the expiration of these agreements, we agreed with the USW to 
extend these agreements indefinitely.  Either party may terminate the agreements by providing the other party with 168 
hours (i.e., seven days) notice.  We continue to bargain with the USW in good faith with the expectation that we will be 
able to reach a mutually acceptable long-term extension of our agreements.  At this time, we do not anticipate any type 
of labor disruption as the USW has committed to “continue working under the current terms and conditions of employment 
until a tentative agreement is reached.”

Pellet Agreement with Essar

On October 6, 2015, we announced that, effective October 5, 2015, we terminated our Pellet Agreement with 
Essar.  Our decision was made as a result of Essar's multiple and material breaches under the agreement.  While the 
agreement has been terminated, we remain open to discussing supplying the Essar steel-making operation in Sault St. 
Marie  or  its  successor  with  pellets  on  commercially  reasonable  terms  consistent  with  a  just-in-time  iron  ore  supply 
arrangement. 

Northshore

On November 17, 2015, we announced that we would be temporarily idling iron ore pellet production at our 
Northshore mining operation in Minnesota.  The idling was a result of a reduction in iron pellet nominations from our 
customers.  Until our domestic customers' blast furnace capacity utilization rates improve, our existing customer demand 
can be satisfied from our current pellet inventory.  We completed the idling of the Northshore mine by the end of November.  
Our Northshore mine could be restarted and return to normal operating levels if recently filed and forthcoming trade 
cases were to result in increased pellet nominations from our customers.  Conversely, if increased iron ore pellet demand 
does not materialize during this period, the idled state of production could be for an extended period of time.  Currently, 
we  anticipate  that  Northshore  mine  will  be  idled  through  the  first  quarter  of  2016.   The  temporary  idling  resulted  in 
reductions in force at the Northshore mine.

North American Coal Operations

On December 22, 2015, we closed the sale of our remaining North American Coal business which included 
Pinnacle mine in West Virginia and Oak Grove mine in Alabama.  Pinnacle mine and Oak Grove mine were sold to 
Seneca Coal Resources, LLC ("Seneca") and the deal structure was a sale of equity interests of our remaining coal 
business.  Additionally, Seneca may pay Cliffs an earn-out of up to $50 million contingent upon the terms of a revenue 
sharing plan which extends through the year 2020.

The  Pinnacle  Complex  includes  the  Pinnacle  and  Green  Ridge  mines,  which  are  underground  low-volatile 
metallurgical  coal  mines.    The  Pinnacle  mine  has  been  in  operation  since  1969.  The  Green  Ridge  mines  became 
operational in 2004. In February 2010, the Green Ridge No. 1 mine was closed permanently due to exhaustion of the 
economic reserves at the mine.  In addition, the Green Ridge No. 2 mine was idled in January 2012.  Both facilities share 
preparation, processing and load-out facilities.

The Oak Grove mine is an underground low-volatile metallurgical coal mine.  The mine has been in operation 

since 1972.  Preparation, processing and rail load-out facilities are located on-site. 

In 2015, the Pinnacle operations produced 2.4 million tons of metallurgical coal and the Oak Grove operations 
produced 1.9 million tons of metallurgical coal.  In 2014, the Pinnacle operations produced 2.7 million tons of metallurgical 
coal and the Oak Grove operations produced 2.3 million tons of metallurgical coal. 

We recorded a gain on the sale of Pinnacle mine and Oak Grove mine of approximately $9.3 million on a pre-
tax basis in the fourth quarter of 2015.  The gain is recorded within Loss from Discontinued Operations, net of tax on the 
Statements of Consolidated Operations.

Prior to the sale, it was determined by management as of March 31, 2015 that our North American Coal operating 
segment met the criteria to be classified as held for sale under ASC 205, Presentation of Financial Statements.  For 
more information regarding the sale and the held for  sale classification of our North American Coal business, see NOTE 
14 - DISCONTINUED OPERATIONS for further information.  

Preferred Stock

In February 2013, we issued 731,250 shares of 7.00% Series A Mandatory Convertible Preferred Stock, Class 
A ("Series A preferred shares"). Under the terms of the Series A preferred shares, when and if declared by our Board of 
Directors, holders of the Series A preferred shares are entitled to cumulative dividends at an annual rate of 7.00 percent 
on the liquidation preference of $1,000 per share.  On January 4, 2016, we announced that, under the terms of our 
Series A preferred shares, the final quarterly dividend otherwise payable upon mandatory conversion of the Series A 
preferred shares on February 1, 2016, would not be paid in cash.  Instead, pursuant to the terms of the Series A preferred 
shares, the conversion rate was increased such that holders of the Series A preferred shares received additional Cliffs' 
common shares in lieu of the accrued dividend at the time of the mandatory conversion.  In accordance with applicable 
law, our Board of Directors determined not to declare a dividend payable in cash.  The number of our common shares 
in the aggregate issued in lieu of the dividend was approximately 1.26 million.  This resulted in an effective conversion 
rate of .9052 common shares, rather than .8621 common shares, per depositary share, each representing one-fortieth 
of a share of Series A preferred shares.  Upon conversion on February 1, 2016, an aggregate of 26.5 million common 
shares were issued, representing 25.2 million common shares issuable upon conversion and 1.3 million that were issued 
in lieu of a final cash dividend.

Exchange Offers

On January 27, 2016, we announced the commencement of private offers to exchange (the "Exchange Offers") 
up to $710 million aggregate principal amount of our newly issued 8.00 percent 1.5 Lien Senior Secured Notes due 2020 
(the “New 1.5 Lien Notes”) for certain outstanding notes (the "Existing Notes") of Cliffs, upon the terms and subject to 
the conditions set forth in our confidential offering memorandum dated January 27, 2016.  Eligible holders were notified 
that they must validly tender their Existing Notes on February 9, 2016 (the “Early Tender Date”), in order to be eligible 
to receive the applicable total exchange consideration which includes an early tender premium.  On February 10, 2016, 
we announced that as of the Early Tender Date, a total of approximately $465.3 million principal amount of Existing 
Notes had been tendered in the Exchange Offers.  We also announced that the Early Tender Date has been extended 
to  February  26,  2016,  and  that  the  exchange  consideration  for  the  3.95  percent  Senior  Notes  due  2018  had  been 
increased.  Accordingly, all Existing Notes tendered prior to the extended Early Tender Date will be eligible to receive 
the total exchange consideration.  The Exchange Offers will expire at 5:00 p.m., New York City time, on February 26, 
2016 and tenders of Existing Notes may no longer be withdrawn after that time, except in certain limited circumstances 
described in the confidential offering memorandum and related letter of transmittal.

Business Segments

Our Company’s primary continuing operations are organized and managed according to product category and 
geographic location: U.S. Iron Ore and Asia Pacific Iron Ore.  As of March 31, 2015, management determined that our 
North American Coal operating segment met the criteria to be classified as held for sale under ASC 205, Presentation 
of Financial Statements.  As such, all current and historical North American Coal operating segment results are included 
in our financial statements and classified within discontinued operations.  Additionally, as a result of the CCAA filing of 
the Bloom Lake Group on January 27, 2015 and the Wabush Group on May 20, 2015, we no longer have a controlling 
interest over the Bloom Lake Group and certain other wholly owned subsidiaries, and we no longer have a controlling 
interest over the Wabush Group. The Bloom Lake Group, Wabush Group and certain of each of their wholly owned 
subsidiaries  were  previously  reported  as  Eastern  Canadian  Iron  Ore  and  Other  reportable  segments.   As  such,  we 
deconsolidated the Bloom Lake Group and certain other wholly-owned subsidiaries as of January 27, 2015.  Additionally, 
as a result of the Wabush Filing on May 20, 2015, we deconsolidated certain Wabush Group wholly-owned subsidiaries 
effective May 20, 2015.  The wholly-owned subsidiaries deconsolidated effective May 20, 2015 are Wabush Group entities 
that were not deconsolidated as part of the deconsolidation effective January 27, 2015.  Financial results prior to the 
respective deconsolidations of the Bloom Lake and Wabush Groups and subsequent expenses directly associated with 
the Canadian Entities are included in our financial statements and classified within discontinued operations.

Sales revenue for the year ended December 31, 2015 decreased $1,359.9 million, or 40.3 percent, from 2014.  
The decrease in sales revenue during 2015 compared to 2014 was primarily attributable to the decrease in market pricing 
for our products, including a reduction of one customer's full-year hot band steel price.  Together these factors negatively 
impacted revenues by $804.4 million for the year ended December 31, 2015. 

Changes in world market pricing impacts our revenues each year.  Iron ore revenues decreased $804.4 million 
in 2015 compared to 2014 primarily due to the decrease in the Platts 62 percent Fe fines spot price, which declined 42.6 
percent to an average price of $56 per ton in 2015, and a decrease in one customer's full-year hot band steel price.  The 
decrease in our realized revenue rates during 2015 compared to 2014 was 22.7 percent and 46.4 percent for our U.S. 
Iron Ore and Asia Pacific Iron Ore operations, respectively.  Additionally, there was a decrease in revenues period-over-
period as a result of lower iron ore sales volumes of $458.1 million for the year ended December 31, 2015.

Refer to “Results of Operations – Segment Information" for additional information regarding the specific factors 

that impacted revenue during the period.

Cost of Goods Sold and Operating Expenses

Cost of goods sold and operating expenses for the years ended December 31, 2015 and 2014 were $1,776.8 

million and $2,487.5 million, respectively, a decrease of $710.7 million, or 28.6 percent year-over-year.

Table of Contents

Cost of goods sold and operating expenses for the year ended December 31, 2015 decreased by $335.0 million 
as operational efficiencies and cost cutting efforts across each of our business units has reduced costs.  Also, as a result 
of favorable foreign exchange rates in 2015 versus 2014, we realized lower costs of $94.6 million.  Additionally, there 
was a decrease in costs period-over-period as a result of lower iron ore sales volumes of $299.1 million for the year 
ended December 31, 2015. These decreases in cost were partially offset by incrementally higher idle costs of $61.5 
million due to the temporary idle of our United Taconite mine which began in the first week of August 2015, the temporary 
idle of the Empire mine which began on June 26, 2015 and then came back on line during October 2015, and the one 
idled production line at our Northshore mine during all of 2015 followed by the complete temporary idle of Northshore 
mine in the end of November 2015.

Selling, general and administrative expenses during the year ended December 31, 2015 decreased $44.7 million 
over 2014.  As a result of the reduction of the workforce, we reduced employment costs for the year ended December 31, 
2015 by $16.7 million.  There were lower severance costs of $14.1 million during the year ended December 31, 2015 
versus 2014.  Also, the year ended December 31, 2015 was impacted favorably by $7.8 million due to a reduction in 
outside service spending and $5.6 million due to a reduction in rent and operating lease spending. 

Impairment of goodwill and other long-lived assets was $3.3 million and $635.5 million during the years ended 
December 31, 2015 and 2014, respectively.  During the year ended December 31, 2014, we recorded goodwill impairment 
of $73.5 million related to our Asia Pacific Iron Ore reporting unit.  We also recorded other long-lived asset impairment 
charges of $562.0 million during 2014. The charges were related to our Asia Pacific Iron Ore operating segment, along 
with impairments charged to reporting units within our Other reportable segments.  The impairment charges were primarily 
a result of management determining that the carrying value of the asset groups may not be recoverable primarily due to 
long-term price forecasts as part of management’s long-range planning process.  Updated estimates of long-term prices 
for all products, specifically the Platts 62 percent Fe fines spot price, which particularly effects the Asia Pacific Iron Ore 
business segment because their contracts correlate heavily to world market spot pricing were lower than prior estimates.  
These estimates were updated based upon current market conditions, macro-economic factors influencing the balance 
of supply and demand for our products and expectations for future cost and capital expenditure requirements.  

Additionally, a new CEO, Lourenco Goncalves, was appointed by the Board of Directors in early August 2014 
and subsequently identified as the CODM in accordance with ASC 280, Segment Reporting.  The new CODM views 
Asia Pacific Iron Ore as a non-core asset and continues to evaluate the business unit for a change in strategy including 
possible  divestiture.    These  factors,  among  other  considerations  utilized  in  the  individual  impairment  assessments, 
indicate that the carrying value of the respective asset group and Asia Pacific Iron Ore goodwill may not be recoverable.

For the year ended December 31, 2015 there was an unfavorable impact of $12.7 million due to the change in 
foreign exchange re-measurement driven primarily by lower Australian bank account balances that are denominated in 
U.S. dollars.  Also, during 2015 there was an unfavorable impact on Miscellaneous - net due to bad debt expense of 
$7.1 million that was recorded in the third quarter of 2015 related to one customer.  

These unfavorable impacts were partially offset by $7.6 million of insurance recoveries related to the clean-up 
of the Pointe Noire oil spill that occurred in September 2013. Additionally, net gain on disposal of assets was $3.4 million 
during the year ended December 31, 2015, compared to a net loss on disposal of assets of $3.5 million in 2014.  The 
net gain on disposal of assets in 2015 was primarily attributable to a $5.0 million gain on the sale of assets and equity 
related to our Global Exploration Group operations during the fourth quarter of 2015.  Results for the Global Exploration 
Group are reported within our Other reportable segments.

The increase in gain on extinguishment of debt during the year ended December 31, 2015 compared to the 
comparable prior year is a result of the corporate debt restructuring and debt repurchases of senior notes trading at a 
discount, as discussed in NOTE 5 - DEBT AND CREDIT FACILITIES. 

Interest expense was unfavorably impacted by $94.1 million for the year ended December 31, 2015 as we entered 
into new credit arrangements during the first quarter of 2015.  Additionally, the year ended December 31, 2015 was 
unfavorably impacted by $11.9 million due to unfavorable interest rates, as discussed in NOTE 5 - DEBT AND CREDIT 
FACILITIES.  The unfavorable impact was offset partially by reduced interest expense of $50.8 million for the year ended 
December 31, 2015 due to the extinguishment of certain Senior Notes and the revolving credit agreement during the 
first quarter of 2015, as discussed in NOTE 5 - DEBT AND CREDIT FACILITIES.  

Additionally, other non-operating income during the year ended December 31, 2014 included a $7.8 million gain

(86.0)

436.5%

Our tax provision for the year ended December 31, 2015 was an expense of $169.3 million and a 54.1 percent 
effective tax rate compared with a benefit of $86.0 million and an effective tax rate of 436.5 percent for the prior-year. 
The change in the income tax expense from the prior-year benefit is due primarily to placement of valuation allowances 
on previously recorded U.S. future tax benefits that management has determined are not recoverable.  The impact of 
foreign operations relates to income in foreign jurisdictions where the statutory rates, ranging from zero percent to 30 
percent, differ from the U.S. statutory rate of 35 percent.  Other items include depletion as well as the reversal of valuation 
allowance related to current year realization of tax benefits.

For the year ended December 31, 2014, income not subject to tax includes the tax benefit of non-taxable interest 
income related to an intercompany note between the U.S. and Canada.  This note was restructured on April 27, 2014 
and no longer results in an income tax benefit after this date.  

See NOTE 9 - INCOME TAXES for further information.

Loss from Discontinued Operations, net of tax

Loss from Discontinued Operations, net of tax was comprised primarily of the loss on discontinued operations 

related to our North American Coal operating segment and our Eastern Canadian Iron Ore operations.

Table of Contents

As of March 31, 2015, management determined that our North American Coal operating segment met the criteria 
to be classified as held for sale under ASC 205, Presentation of Financial Statements.  As such, all current year and 
historical North American Coal operating segment results are included in our financial statements and classified within 
discontinued operations.  The Loss from Discontinued Operations, net of tax related to the North American Coal operating 
segment was $152.4 million and $1,134.5 million for the years ended December 31, 2015 and 2014, respectively.

In January 2015, we announced that the Bloom Lake Group commenced restructuring proceedings in Montreal, 
Quebec under the CCAA.  At that time, we had suspended Bloom Lake operations and for several months had been 
exploring options to sell certain of our Canadian assets, among other initiatives.  Effective January 27, 2015, following 
the CCAA filing of the Bloom Lake Group, we deconsolidated the Bloom Lake Group and certain other wholly-owned 
subsidiaries comprising substantially all of our Canadian operations.  Additionally, on May 20, 2015, the Wabush Group 
commenced restructuring proceedings in Montreal, Quebec under the CCAA which resulted in the deconsolidation of 
the  remaining  Wabush  Group  entities  that  were  not  previously  deconsolidated.   The  Wabush  Group  was  no  longer 
generating revenues and was not able to meet its obligations as they came due.  As a result of this action, the CCAA 
protections granted to the Bloom Lake Group were extended to include the Wabush Group to facilitate the reorganization 
of each of their businesses and operations.  Financial results prior to the respective deconsolidations of the Bloom Lake 
and Wabush Groups and subsequent expenses directly associated with the Canadian Entities are included in our financial 
statements and classified within discontinued operations.  The Loss from Discontinued Operations, net of tax related to 
the deconsolidated Canadian Entities was $739.7 million and $7,233.5 million for the years ended December 31, 2015 
and 2014, respectively.

Refer to NOTE 14 - DISCONTINUED OPERATIONS for further information.

Noncontrolling Interest

Noncontrolling interest is comprised primarily of our consolidated, but less-than-wholly owned subsidiary at our 
Empire mining venture and through the CCAA filing on January 27, 2015, the Bloom Lake operations.  The net loss 
attributable to the noncontrolling interest related to Bloom Lake was $7.7 million and $1,113.3 million for the years ended 
December 31, 2015 and 2014, respectively.  The net income attributable to the noncontrolling interest related to the 
Empire mining venture was $8.6 million and $26.9 million for the years ended December 31, 2015 and 2014, respectively.

Sales revenue for the year ended December 31, 2014 decreased $517.6 million, or 13.3 percent, from 2013. 
The decrease in sales revenue during 2014 compared to 2013 was primarily attributable to the decrease in market pricing 
for our products, which impacted revenues by $648.4 million for the year ended December 31, 2014.  Changes in world 
market pricing impacts our revenues each year.  During 2014, iron ore revenues were impacted primarily by the decrease 
in the Platts 62 percent Fe fines spot price, which declined 28.5 percent to an average price of $97 per ton, resulting in 
decreased revenues of $648.4 million.  The decrease in our realized revenue rates during 2014 compared to 2013 was 
9.5 percent and 32.8 percent for our U.S. Iron Ore and Asia Pacific Iron Ore, respectively.  This decrease was partially 
offset by an increase in revenues period-over-period as a result of higher iron ore sales volumes of 1.0 million tons or 
$115.6 million for the year ended December 31, 2014.

Cost of Goods Sold and Operating Expenses

Cost of goods sold and operating expenses for the years ended December 31, 2014 and 2013 were $2,487.5 

million and $2,406.4 million, respectively, an increase of $81.1 million, or 3.4 percent, year-over-year.

Cost of goods sold and operating expenses for the year ended December 31, 2014 increased period-over-period 
primarily as a result of higher iron ore sales volumes of $71.1 million for the year ended December 31, 2014.  Additionally, 
we incurred higher costs at our U.S. Iron Ore operations of $34.4 million primarily due to increased repairs and maintenance 
along with higher costs related to increased energy rates in early 2014.  Partially offsetting these increases was a decrease 
in idle costs period-over-period of $48.9 million for the year ended December 31, 2014.

Refer to “Results of Operations – Segment Information” for additional information regarding the specific factors 

that impacted our operating results during the period.

Selling, general and administrative expenses during the year ended December 31, 2014 decreased $9.1 million 
over 2013.   The year ended December 31, 2014  was impacted favorably by $22.2 million  for employment costs related 
to cost savings actions and reduced year-over-year expense of $10.5 million related to pension and other postemployment 
benefits.  Offsetting these cost reductions was an increase in costs related to the proxy contest and the change in control 
of  the  majority  of  our  Board  of  Directors.    We  incurred  substantial  costs  associated  with  various  advisors,  including 
bankers, attorneys and others.  Costs associated with these events were approximately $26.2 million for the year ended 
December 31, 2014. 

Impairment of goodwill and other long-lived assets were $635.5 million and $14.3 million during the years ended 
December 31, 2014 and 2013, respectively.  During the year ended December 31, 2014, we recorded goodwill impairment 
of $73.5 million related to our Asia Pacific Iron Ore reporting unit.  We also recorded other long-lived asset impairment 
charges of $562.0 million during 2014. The charges are related to our Asia Pacific Iron Ore operating segment, along 
with impairments charged to reporting units within our Other reportable segments.  The impairment charges were primarily 
a result of management determining that the carrying value of the asset groups may not be recoverable primarily due to 
long-term price forecasts as part of management’s long-range planning process.  Updated estimates of long-term prices 
for all products, specifically the Platts 62 percent Fe fines spot price, which particularly effects the Asia Pacific Iron Ore 
business segment because their contracts correlate heavily to world market spot pricing were lower than prior estimates.  
These estimates were updated based upon current market conditions, macro-economic factors influencing the balance 
of supply and demand for our products and expectations for future cost and capital expenditure requirements.  Additionally, 
a new CEO, Lourenco Goncalves, was appointed by the Board of Directors in early August 2014 and subsequently 
identified as the CODM in accordance with ASC 280, Segment Reporting.  The CODM views Asia Pacific Iron Ore as a 
non-core asset and continues to evaluate the business unit for a change in strategy including possible divestiture.  These 
factors, among other considerations utilized in the individual impairment assessments, indicate that the carrying value 
of the respective asset groups and Asia Pacific Iron Ore goodwill may not be recoverable.  Refer to NOTE 6 - FAIR 
VALUE OF FINANCIAL INSTRUMENTS for further information.

For the year ended December 31, 2014, there was an unfavorable incremental impact of $24.2 million due to 
the change in foreign exchange re-measurement on short-term intercompany notes, Australian bank accounts that are 
denominated in U.S. dollars and certain monetary financial assets and liabilities, which are denominated in something 
other than the functional currency of the entity. 

Net loss on disposal of assets was $3.5 million during the year ended December 31, 2014, compared to a net 
gain on disposal of assets of $19.4 million in 2013.  The net gain on disposal of assets in 2013 was primarily attributable 
to our final settlement of the sale of our beneficial interest in the mining tenements and certain infrastructure of Cockatoo 
Island during the second quarter of 2013. Upon final settlement of the sale, we extinguished approximately $18.6 million 
related to the estimated cost of the rehabilitation. Our 50 percent equity interest in Cockatoo Island was included in our 
Asia Pacific operations prior to the sale.

Exploration costs decreased by $11.3 million during the year ended December 31, 2014 from 2013, primarily 
due to decreases in costs at our Global Exploration Group operations.  The Global Exploration Group is reported within 
our Other reportable segments.  Our Global Exploration Group had cost decreases of $8.0 million in 2014 over 2013, 
due to lower overhead and professional services spend.  In alignment with our capital allocation strategy, we had minimal 
levels of exploration spending in 2014 and that has continued into the subsequent years.

The decrease in interest expense in 2014 compared to 2013 was attributable to reduced interest expense of 
$7.1 million related to unamortized debt issuance costs being expensed upon our repayment of the balance of the term 
loan in February 2013 and $7.9 million related to a decrease in borrowings on the revolving credit facility.  This decrease 
was offset partially by additional interest expense related to the change in borrowing capacity of our revolving credit 
facility which resulted in $3.7 million of unamortized debt issuance costs being expensed as of the effective date of the 
amendment and increased interest rates on the 3.95 senior notes which resulted in $4.6 million of additional interest 
expense.  Refer to NOTE 5 - DEBT AND CREDIT FACILITIES for further information. 

The $16.2 million gain on extinguishment of debt is related to our repurchase of debt in the fourth quarter of 

2014.   Refer to NOTE 5 - DEBT AND CREDIT FACILITIES for further information.

Our tax provision for the year ended December 31, 2014 was a benefit of $86.0 million and a 436.5 percent 
effective tax rate compared with an expense of $237.6 million and an effective tax rate of 20.0 percent for the prior-year. 
The change in the income tax benefit from the prior-year expense is due primarily to the impairment of global long-lived 
assets offset by valuation allowances on future tax benefits that management has determined are not recoverable and 
the settlement of a financial guaranty.  The impact of foreign operations relates to losses in foreign jurisdictions where 
the statutory rates, ranging from zero percent to 30 percent, differ from the U.S. statutory rate of 35 percent.  Other items 
include non-deductible goodwill impairment as well as a decrease in the tax benefit from interest income not subject to 
tax.

For the years ended December 31, 2014 and 2013, income not subject to tax includes the tax benefit of non-

April 27, 2014 and no longer results in an income tax benefit after this date.

Equity Loss from Ventures

Equity loss from ventures for the year ended December 31, 2014 of $9.9 million compares to equity loss from 
ventures for the year ended December 31, 2013 of $74.4 million.  The equity loss from ventures for the year ended 
December 31, 2014 primarily is comprised of the impairment charge of $9.2 million related to a Global Exploration Group 
investment.  The equity loss from ventures for the year ended December 31, 2013 primarily is comprised of the impairment 
charge of $67.6 million related to our 30 percent ownership interest in Amapá, the sale of which was approved by the 
Board of Directors in December 2012.  The sale closed in the fourth quarter of 2013.

Loss from Discontinued Operations, net of tax 

Loss from Discontinued Operations, net of tax was comprised primarily of the loss on discontinued operations

Discontinued Operations, net of tax related to the North American Coal operating segment was $1,134.5 million and $9.3 
million for the years ended December 31, 2014 and 2013, respectively.  The Loss from Discontinued Operations, net of 
tax related to the deconsolidated Canadian Entities was $7,233.5 million and $509.8 million for the years ended December 
31, 2014 and 2013, respectively.

Refer to NOTE 14 - DISCONTINUED OPERATIONS for further information.

Noncontrolling Interest

Noncontrolling interest primarily is comprised of our consolidated, but less-than-wholly owned subsidiary at our 
Empire mining venture and through the CCAA filing on January 27, 2015, the Bloom Lake operations.  The net loss 
attributable to the noncontrolling interest related to Bloom Lake was $1,113.3 million for the year ended December 31, 
2014 compared to net loss attributable to the noncontrolling interest of $66.5 million for the year ended December 31, 
2013.  The net income attributable to the noncontrolling interest of the Empire mining venture was $26.9 and $20.7 million 
for the years ended December 31, 2014 and 2013, respectively.  

Results of Operations – Segment Information 

We have historically evaluated segment performance based on sales margin, defined as revenues less cost of 
goods sold, and operating expenses identifiable to each segment.  Additionally, beginning in the third quarter of 2014, 
concurrent with the change in control on July 29, 2014, management began to evaluate segment performance based 
on EBITDA, defined as net income (loss) before interest, income taxes, depreciation, depletion and amortization, and 
Adjusted EBITDA, defined as EBITDA excluding certain items such as impairment of goodwill and other long-lived assets, 
impacts of discontinued operations, extinguishment of debt, severance and contractor termination costs and other costs 
associated  with  the  change  in  control,  foreign  currency  remeasurement,  certain  supplies  inventory  write-offs,  and 
intersegment corporate allocations of selling, general and administrative costs.  Management uses and believes that 
investors benefit from referring to these measures in evaluating operating and financial results, as well as in planning, 
forecasting and analyzing future periods as these financial measures approximate the cash flows associated with the 
operational earnings.

  Revenues also exclude venture partner cost reimbursements. 
2 Tons are long tons (2,240 pounds).

Sales margin for U.S. Iron Ore was $227.1 million for the year ended December 31, 2015, compared with the 
sales  margin  of  $710.4  million  for  the  year  ended  December 31,  2014.    The  decline  compared  to  the  prior  year  is 
attributable to a decrease in revenue of $981.1 million partially offset by a decrease in cost of goods sold and operating 
expenses of $497.8 million.  Sales margin per ton decreased 59.6 percent to $13.13 during the year ended December 31, 
2015 compared to 2014.

Revenue decreased by $867.3 million, excluding the decrease of $113.8 million of freight and reimbursements, 

from the prior year, predominantly due to:

•  The average year-to-date realized product revenue rate declined by $23.24 per ton or 22.7 percent to 
$79.12 per ton in 2015, which resulted in a decrease of $401.9 million.  This decline is a result of:

Changes  in  customer  pricing  negatively  affected  the  realized  revenue  rate  by  $9  per  ton  driven 
primarily by the reduction in Platts 62 percent Fe fines spot price as well as other indices referenced 
in customer contracts;

Realized revenue rates impacted negatively by $7 per ton primarily as a result of one major customer 
contract with a pricing mechanism affected by a reduction in their full-year hot band steel pricing; 
and

62

 
 
 
 
Table of Contents

Realized revenue rates impacted negatively by $5 per ton related to one major customer contract 
with a reduced average selling price due to a change in the pricing mechanism as prescribed in the 
contract which shifted the contract from a fixed rate to a rate impacted by the Platts 62 percent Fe 
fines spot price, as well as other market rates plus the impact and timing of carryover tons.

• 

Lower sales volumes of 4,548 thousand tons or $465.4 million due to:

A lower nomination in 2015 from one customer due to reduced 2015 demand, reduced demand from 
a customer due to the idling of its blast furnace beginning in March 2015 and the expiration of a 
contract with one customer at the end of 2014; and

Lower sales to one customer in 2015 due to the termination of a contract in the fourth quarter of the 
current year.

These decreases were partially offset by higher sales to one customer throughout 2015 due to a 
spot contract with the customer that began in the fourth quarter of 2014.

Cost of goods sold and operating expenses in 2015 decreased $384.0 million, excluding the decrease of $113.8 

million of freight and reimbursements from the prior year, predominantly as a result of:

• 

Lower costs in 2015 in comparison to the prior year primarily driven by the reduction in salaried workforce 
headcount, along with reduced maintenance and repair costs based on cost reduction initiatives and 
condition-based monitoring, reduced stripping costs at Tilden and Hibbing based on new mine plans, 
and the year-over-year reduction in energy rates; and

•  Decreased sales volumes, as discussed above, that decreased costs by $305.3 million compared to the 

prior year. 

•  Partially offset by increased idle costs of $61.5 million due to the idle of United Taconite mine which 
began in the first week of August 2015, the idle of the Empire mine which began on June 26 2015 and 
ended in mid-October 2015, and one idled production line at our Northshore mine during all of 2015, 
until the complete idle of Northshore mine in the end of November 2015.

Production

Cliffs' share of production tons in its U.S. Iron Ore segment decreased by 13.9 percent in 2015 when compared 
to 2014.  Empire mine had a decrease in production of 1,045 thousand tons related to the idling of Empire that began 
on June 26, 2015 and ended during mid-October of 2015.  United Taconite mine had a decrease in production of 1,866 
thousand tons during 2015 compared to 2014, primarily due to the idling of United Taconite mine that began the first 
week of August 2015.  There was a decrease in production of 965 thousand tons at the Northshore mine during 2015, 
as we ran a three furnace operation throughout 2015 until the complete idle of Northshore mine in the end of November 
2015.  This is  compared to 2014 when we ran a two furnace operation at Northshore for the majority of the first quarter 
and then started up one idled furnace in February and the other in March.

Sales margin for our Asia Pacific Iron Ore segment decreased to $9.4 million during the year ended December 31, 
2015 compared with $121.7 million for the same period in 2014.  Sales margin per ton decreased 92.4 percent to $0.80 
per ton in 2015 compared to 2014 primarily as a result of decreased pricing as discussed below.

Revenue decreased by $395.5 million during the year ended December 31, 2015 over the prior year, excluding 

the increase of $16.7 million of freight and reimbursements, primarily as a result of:

•  An overall decrease to the average realized revenue rate, which resulted in a decrease of $402.5 million, 
primarily as a result of a decrease in the Platts 62 percent Fe fines spot price to an average of $56 per 
ton from $97 per ton in the prior year. 

•  This decrease is partially offset by the higher sales volume of 11.6 million tons during the year ended 
December 31, 2015 compared with 11.5 million tons resulting in an increase in revenue of $7.3 million.

Cost of goods sold and operating expenses in the year ended December 31, 2015 decreased $283.2 million, 

excluding the increase of $16.7 million of freight and reimbursements, compared to 2014 primarily as a result of: 

•  A reduction in depreciation, amortization and depletion expense of $120.6 million primarily due to the 
long-lived asset impairments taken during the second half of 2014 and reduced mining costs of $79.4 
million mainly due to decreased mining and hauling volumes and increases in productivity related to 
maintenance, hauling and train loading, and lower headcount; and

•  Favorable foreign exchange rate variances of $94.6 million or $8 per metric ton.

64

 
 
 
 
 
Table of Contents

•  These decreases were offset partially by higher sales volumes, as discussed above, that resulted in 

increased costs of $6.2 million compared to the prior year.

Production

Production at our Asia Pacific Iron Ore segment during the year ended December 31, 2015 remained consistent 
when compared to 2014 with a slight increase of 370 thousand production tons or 3.3 percent.  The increase in production 
tons compared to the prior year is mainly attributable to increased rail capacity.

1 Excludes revenues and expenses related to domestic freight, which are offsetting and have no impact on sales margin.  
Revenues also exclude venture partner cost reimbursements. 
2 Tons are long tons (2,240 pounds).

Sales margin for U.S. Iron Ore was $710.4 million for the year ended December 31, 2014, compared with the 
sales  margin  of  $901.9  million  for  the  year  ended  December 31,  2013.   The  decline  compared  to  the  prior  year  is 
attributable  to a decrease in  revenue  of $161.4  million  as well as an  increase in  cost  of goods  sold  and  operating 
expenses of $30.1 million.  Sales margin per ton decreased 23.2 percent to $32.53 during the year ended December 31, 
2014 compared to 2013.

Revenue decreased by $172.8 million, excluding the increase of $11.4 million of freight and reimbursements, 

from the prior year, predominantly due to:

•  The average year-to-date realized product revenue rate declined by $10.72 per ton or 9.5 percent to 
$102.36 per ton in 2014, which resulted in a decrease of $233.6 million.  This decline is a result of:

Changes in customer pricing negatively affected the realized revenue rate by $6 per ton driven 
primarily by the period-over-period reduction in Platts 62 percent Fe fines spot price and by 
new base pricing from an additional contract; and

66

 
 
 
 
Table of Contents

Realized  revenue  rates  impacted  negatively  by  $5  per  ton  related  to  one  major  customer 
contract with a reduced average selling price due to a contractual change in the 2014 pricing 
mechanism.

•  Primarily offset by higher sales volumes of 541 thousand tons or $60.8 million due to:

Higher Great Lakes sales due to increased contracted tons in 2014 from two customers due 
to separate contract extensions/amendments, higher demand from a customer due to the Great 
Lakes freeze preventing the customer from reaching its self-produced ore, along with increased 
nominations in 2014 for two major customer contracts.

Partially offset by decreased export sales due to increased 2014 Great Lakes nominations and 
low market pricing providing a disincentive for spot shipment opportunities along with reduced 
spot sales that occurred with one customer in the prior-year not recurring for as much tonnage 
in 2014.

Cost of goods sold and operating expenses in 2014 increased $18.7 million, excluding the increase of $11.4 

million of freight and reimbursements from the prior year, predominantly as a result of:

•  Higher costs related to increased mobile equipment repairs and increased maintenance and repair 
costs primarily driven by increased kiln repairs at Empire in 2014 due to the 2016 life-of-mine extension, 
mill repair at the Hibbing mine, along with higher costs related to increased energy rates in the first 
quarter of 2014; and

• 

Increased sales volumes, as discussed above, that increased costs by $33.2 million compared to the 
prior year. 

•  Partially offset by lower idle costs of $48.9 million due to restarting the two production lines at our 
Northshore mine during the first quarter of 2014 that were previously idled in January 2013 and the 
non-recurrence of the 2013 summer shutdown of the Empire mine in 2014.

Production

Cliffs' share of production tons in its U.S. Iron Ore segment increased by 10.7 percent in 2014 when compared 
to 2013.  There was increased production at our Empire mine of 1.3 million tons in 2014 as a result of the non-recurrence 
of the summer shutdown that occurred in 2013, beginning early in the second quarter and ending in the third quarter.  
Additionally, there was an increase in production of 1.4 million tons at the Northshore mine during 2014, as we restarted 
the two idled furnaces in the first quarter of 2014.  We had previously idled two of the four furnaces at the Northshore 
mine in January 2013. These increases were partially offset by decreased production of 260 thousand tons at our United 
Taconite mine due to extreme weather and unplanned maintenance outages.

Sales  margin  for  our  Asia  Pacific  Iron  Ore  segment  decreased  to  $121.7  million  during  the  year  ended 
December 31, 2014 compared with $367.1 million for the same period in 2013.  Sales margin per metric ton decreased 
68.3 percent to $10.55 per metric ton in 2014 compared to 2013.

Revenue decreased by $364.5 million during the year ended December 31, 2014 over the prior year, excluding 

the increase of $6.9 million of freight and reimbursements, primarily as a result of:

•  An overall decrease to the average realized revenue rate, which resulted in a decrease of $414.8 million, 
primarily as a result of a decrease in the Platts 62 percent Fe fines spot price to an average of $97 per 
ton from $135 per ton in the prior year, 

•  Partially offset by the higher sales volume of 11.5 million tons during the year ended December 31, 2014 
compared with 11.0 million tons during the prior year due to strong rail deliveries and increased production, 
resulting in an increase in revenue of $54.8 million.

Cost of goods sold and operating expenses in the year ended December 31, 2014 decreased $119.1 million, 

excluding the increase of $6.9 million of freight and reimbursements, compared to 2013 primarily as a result of: 

•  Reduced mining costs of $81.2 million mainly due to lower mining contractor costs primarily resulting 
from  a  focus  on  efficiencies  across  the  operation,  lower  sales  royalties  of  $23.9  million  primarily 
attributable to the decline in the Platts 62 percent Fe fines spot price, and lower logistics costs of $12.0 
million primarily attributable to the finalization of the port dispute.  These cost savings are partially offset 
by an increase in site administration expenses of $9.6 million due to realignment of head count to the 
sites and severance payments of $1.6 million; and

68

 
 
 
 
Table of Contents

•  Favorable foreign exchange rate variances of $54.3 million or $5 per metric ton.

•  These decreases were offset partially by higher sales volumes, as discussed above, that resulted in 

increased costs of $37.9 million compared to the prior year.

Production

Production at our Asia Pacific Iron Ore segment increased 243 thousand metric tons or 2.2 percent during the 
year ended December 31, 2014 when compared to 2013.  The increase in production tons compared to the prior year  
is mainly attributable to increased rail capacity as there were less train delays and better loading procedures implemented 
to get more tons into each wagon.

Liquidity, Cash Flows and Capital Resources

Our primary sources of liquidity are cash generated from our operating and financing activities.  Our capital 
allocation process is focused on prioritizing all potential uses of future cash flows.  We are focused on the preservation 
of liquidity in our business through the maximization of cash generation of our operations as well as reducing operating 
costs, limiting capital investments to regulatory and permission to operate related projects and lowering selling, general 
and administrative expenses. We also may seek to reduce our debt, including, without limitation, through repurchases 
or exchanges of our debt securities.  We believe these efforts, which have been underway for several quarters and will 
continue for the foreseeable future, are critical in light of the challenging market conditions arising from the reduced 
demand for our products and volatility in global commodity prices we experienced during 2015.

Based on our outlook for 2016, which is subject to continued changing demand from steelmakers that utilize our 
products and volatility in iron ore and domestic steel prices, we expect our anticipated capital expenditures and cash 
requirements to service our debt obligations during the next 12 months to exceed our estimated operating cash flows.  
Despite this, we maintain sufficient liquidity through the cash on our balance sheet and the availability provided by our 
ABL Facility to fund our normal business operations, including the servicing of our debt obligations, and we expect to be 
able to fund these requirements for the next 12 months.

If we see reduced demand from our customers and/or iron ore or steel prices were to deteriorate further during 
2016 we would face further pressure on our available liquidity.  If this was the case, we would need to consider the sale 
of assets, further expense reductions and the possibility of refinancing our existing debt.  There is a possibility that these 
further actions would not be sufficient to maintain adequate levels of available liquidity particularly if  industry conditions 
deteriorated severely.

Refer to “Outlook” for additional guidance regarding expected future results, including projections on pricing, 

sales volume and production for our various businesses.

The following discussion summarizes the significant activities impacting our cash flows during 2015 as well as 
those expected to impact our future cash flows over the next 12 months.  Refer to the Statements of Consolidated Cash 
Flows for additional information.

Operating Activities   

Net cash provided by operating activities decreased to $37.9 million for the year ended December 31, 2015, 
compared to cash provided by operating activities of $358.9 million for 2014.  The decrease in operating cash flows in 
2015 was primarily due to lower operating results as previously discussed, which was partially offset by an income tax 
refund of $211.4 million, mainly related to the U.S.  Positively affecting our operating cash flows in 2015 and continuing 
into 2016 are the decreased costs associated with the temporary idles of United Taconite mine and Northshore mine. 

Net cash provided by operating activities decreased to $358.9 million for the year ended December 31, 2014, 
compared to Net cash provided by operating activities of $1,145.9 million for 2013. The decrease in operating cash flows 
in 2014 was primarily due to lower operating results as previously discussed. 

Throughout 2015, the Platts 62 percent Fe fines spot price has been driven down by a combination of reduced 
domestic steel demand from China and increased global iron ore production leading to excess supply, as well as mining 
cost deflation and a sharp fall in Australian and Brazilian currencies versus the U.S. dollar.  In 2016, we do not expect 
to see meaningful improvement in iron ore prices without significant changes to the global iron ore supply-demand picture.

The iron ore supply-demand situation has not only adversely impacted iron ore producers, but also the global 
steel industry. Currently, the global steel industry is experiencing its worst conditions in over a decade, with prices for 
products falling even lower than those realized during the most recent recession - the 2008 global financial crisis. We 

69

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

believe that very low cost iron ore has contributed substantially to foreign steel exported out of China and other countries 
into the U.S. market.  As a result of these imports, as well as the continued weakening of the oil and gas sector, domestic 
pricing for steel has been depressed and in turn, our customers' demand for pellets has fallen.  In 2016, we expect these 
conditions to improve as recently imposed duties on unfairly traded steel should curb the steel imports entering the U.S, 
and as a result we expect to see domestic steel pricing rising throughout 2016.

If necessary, our efficient tax structure allows us to repatriate cash from our foreign operations.  Our U.S. cash 
and cash equivalents balance at December 31, 2015 was $213.6 million, or approximately 74.9 percent of our consolidated 
total cash and cash equivalents balance of $285.2 million. 

Investing Activities 

Net cash used in investing activities was $103.2 million for the year ended December 31, 2015, compared with 
$103.6 million for 2014.  We had capital expenditures of $80.8 million and $284.1 million for the years ended December 31, 
2015 and 2014, respectively.  Offsetting our investments in property, plant and equipment, during 2014, we had cash 
proceeds from investing activities of $155.0 million from the sale of CLCC.  

Net  cash  used  by  investing  activities was $103.6  million for  the year  ended December 31,  2014,  compared 
with $811.3  million for 2013.  We  had  capital  expenditures  of $284.1  million and $861.6  million for 
the years 
ended December 31, 2014 and 2013, respectively.  Up until the first quarter of 2014, our main capital investment focus 
was on the construction of the Bloom Lake mine's operations, at which time we placed the Phase II expansion on hold.  
We subsequently determined that the Phase II expansion of the Bloom Lake mine was no longer a viable option for us 
and we shifted our focus to considering available possibilities and executing an exit option for Eastern Canadian Iron 
Ore operations that minimizes the cash outflows and associated liabilities.  In December 2014, iron ore production at 
the Bloom Lake mine was suspended and the Bloom Lake mine was placed in ‘‘care-and-maintenance’’ mode.  Prior to 
Bloom Lake mine entering "care and maintenance" mode, we spent approximately $51 million and approximately $426 
million on the ramp-up and expansion projects at the Bloom Lake mine during the years ended December 31, 2014 and 
2013, respectively, which predominately relates to work performed in 2013.  

Additionally, we spent approximately $81 million, $232 million and $394 million globally on expenditures related 
to sustaining capital during 2015, 2014 and 2013, respectively.  Sustaining capital spend includes infrastructure, mobile 
equipment, environmental, safety, fixed equipment, product quality and health.

In alignment with our strategy to focus on allocating capital among key priorities related to liquidity management, 
and business investment, we anticipate total cash used for capital expenditures in 2016 to be approximately $50 million, 
the vast majority of which relates to our U.S. Iron Ore operations.

Financing Activities 

Net cash provided by financing activities was $61.0 million for the year ended December 31, 2015, compared 
with net cash used in financing activities of $288.3 million for 2014.  Net cash provided by financing activities included 
the issuance of First Lien Notes, which resulted in proceeds of $503.5 million which were offset partially by the repurchase 
of senior notes of $225.9 million and debt issuance costs of $33.6 million.  Additionally, net cash used by financing 
activities during 2015 and 2014  included $45.4 million and $20.9 million, respectively, for the repayment of the Canadian 
equipment loans, and $51.2 million of preferred dividend distributions in each of those periods.  On January 4, 2016, we 
announced that under the terms of our 7.00 percent Series A Mandatory Convertible Preferred Stock, Class A ("Series 
A preferred stock"), the final quarterly dividend would not be paid in cash.  Refer to NOTE 21 - SUBSEQUENT EVENTS 
for further information.  The year ended December 31, 2014 also included common dividend distributions of $92.5 million.  
On January 26, 2015, we announced that our Board of Directors had decided to eliminate the quarterly dividend of $0.15 
per share on our common shares.  The decision was applicable to the first quarter of 2015 and all subsequent quarters.  

We anticipate that the remaining balance of the Canadian equipment loans that were guaranteed by the Company 
of approximately $97 million will be re-paid from available cash within the next 12 months and as a result approximately 
$74 million of letter of credit obligations associated with these guarantees will be released as well.  We also had distributions 
of partnership equity of $40.6 million for the year ended December 31, 2015 and we anticipate approximately $47 million 
in partnership equity will be distributed within the next 12 months.

Net cash used in financing activities was $288.3 million for the year ended December 31, 2014, compared with 
net cash used in financing activities of $171.9 million for 2013.  For the year ended December 31, 2013, net cash used 
includes dividend distributions of $127.6 million.  In 2013, we had net repayments under our credit facilities of $325.0 
million, which was partially offset by cash provided by financing activities of $164.8 million from the Canadian equipment 
loans.  Additionally, we completed public offerings of 29.25 million depositary shares and 10.35 million common shares, 

70

 
 
 
 
 
 
 
 
 
 
Table of Contents

resulting in net proceeds of $709.4 million and $285.3 million, respectively, after underwriting fees and discounts, of 
which a portion of the net proceeds were used to repay the $847.1 million outstanding under the term loan.

(1)   On March 30, 2015 we eliminated our revolving credit facility and replaced it with the ABL Facility
(2)   The ABL Facility has the maximum borrowing base of $550 million, determined by applying customary 

advance rates to eligible accounts receivable, inventory and certain mobile equipment.

Our primary source of funding is our ABL Facility, which matures on March 30, 2020.  We also have cash on 
hand, generated by the business, which totaled $285.2 million as of December 31, 2015.  The combination of cash and 
availability under the ABL Facility gives us approximately $464.4 million in liquidity entering the first quarter of 2016, 
which is expected to be used to fund operations, letter of credit obligations, sustaining capital expenditures and other 
cash commitments for at least the next 12 months.  Based on anticipated cash used from financing activities, letters of 
credit obligations will decrease by approximately $76 million in the next 12 months.  

As of December 31, 2015, we were in compliance with the ABL Facility liquidity requirements and, therefore, the 
springing financial covenant requiring a minimum Fixed Charge Coverage Ratio of 1.0 to 1.0 was not applicable. We 
believe that the cash on hand and the ABL Facility provide us sufficient liquidity to support our operating, investing and 
financing activities.  

As previously noted, on January 27, 2016, we announced the Exchange Offers up to $710 million aggregate 
principal amount of our New 1.5 Lien Notes due 2020 for certain Existing Notes of Cliffs, upon the terms and subject to 
the conditions set forth in our confidential offering memorandum dated January 27, 2016.  To the extent that Existing 
Notes are exchanged, the capability to issue New 1.5 Lien Notes, subject to compliance with the Fixed Charge Coverage 
Ratio under our ABL Facility for purposes of additional liquidity, is proportionally reduced.  Furthermore, the ability to 
issue these secured notes could be limited by market conditions.  If demand for our products and pricing deteriorates 
further and persists for a continued period of time, we believe our ability to maintain the required Fixed Charge Coverage 
Ratio of 1.0 to 1.0 could be difficult.  

Off-Balance Sheet Arrangements

In the normal course of business, we are a party to certain arrangements that are not reflected on our Statements 
of Consolidated Financial Position.  These arrangements include minimum "take or pay" purchase commitments, such 
as minimum electric power demand charges, minimum coal, diesel and natural gas purchase commitments, minimum 
railroad transportation commitments and minimum port facility usage commitments; financial instruments with off-balance 
sheet risk, such as bank letters of credit and bank guarantees; and operating leases, which primarily relate to equipment 
and office space.

Market Risks 

We are subject to a variety of risks, including those caused by changes in commodity prices, foreign currency 
exchange rates and interest rates.  We have established policies and procedures to manage such risks; however, certain 
risks are beyond our control.

72

 
 
 
 
 
 
 
 
Table of Contents

Pricing Risks

Commodity Price Risk

Our consolidated revenues include the sale of iron ore pellets, iron ore lump and iron ore fines.  Our financial 
results can vary significantly as a result of fluctuations in the market prices of iron ore.  World market prices for these 
commodities have fluctuated historically and are affected by numerous factors beyond our control.  The world market 
price that most commonly is utilized in our iron ore sales contracts is the Platts 62 percent Fe fines spot rate pricing, 
which can fluctuate widely due to numerous factors, such as global economic growth or contraction, change in demand 
for steel or changes in availability of supply.  

Provisional Pricing Arrangements

Certain of our U.S. Iron Ore and Asia Pacific Iron Ore customer supply agreements specify provisional price 
calculations, where the pricing mechanisms generally are based on market pricing, with the final revenue rate to be 
based on market inputs at a specified point in time in the future, per the terms of the supply agreements.  The difference 
between the provisionally agreed-upon price and the estimated final revenue rate is characterized as a derivative and 
is required to be accounted for separately once the revenue has been recognized.  The derivative instrument is adjusted 
to  fair  value  through  Product  revenues  each  reporting  period  based  upon  current  market  data  and  forward-looking 
estimates provided by management until the final revenue rate is determined. 

At December 31, 2015, we recorded $2.0 million as derivative assets included in Other current assets and $3.4 
million as derivative liabilities included in Other current liabilities in the Statements of Consolidated Financial Position 
related to our estimate of final revenue rate with our U.S. Iron Ore and Asia Pacific Iron Ore customers.  These amounts 
represent the difference between the provisional price agreed upon with our customers based on the supply agreement 
terms and our estimate of the final sales rate based on the price calculations established in the supply agreements.  As 
a result, we recognized a net $1.4 million decrease, respectively, in Product revenues in the Statements of Consolidated 
Operations for the year ended December 31, 2015 related to these arrangements.

Customer Supply Agreements 

A certain supply agreement with one U.S. Iron Ore customer provides for supplemental revenue or refunds based 
on the customer’s average annual steel pricing at the time the product is consumed in the customer’s blast furnace.  The 
supplemental pricing is characterized as a freestanding derivative, which is finalized based on a future price, and is 
adjusted to fair value as a revenue adjustment each reporting period until the pellets are consumed and the amounts 
are settled.  The fair value of the instrument is determined using an income approach based on an estimate of the annual 
realized price of hot-rolled steel at the steelmaker’s facilities.

At December 31, 2015, we had derivative assets of $5.8 million, representing the fair value of the pricing factors, 
based upon the amount of unconsumed tons and an estimated average hot-band steel price related to the period in 
which the tons are expected to be consumed in the customer’s blast furnace at each respective steelmaking facility, 
subject to final pricing at a future date.  This compares with derivative assets of $63.2 million as of December 31, 2014.  
We estimate that a $75 positive change in the average hot-band steel price realized from the December 31, 2015 estimated 
price recorded would cause the fair value of the derivative instrument to increase by approximately $51.9 million or a 
$75 negative change in the average hot-band steel price realized from the December 31, 2015 estimated price recorded 
would cause the fair value of the derivative instrument to decrease by approximately $44.1 million, thereby impacting 
our consolidated revenues by the same amount.

We have not entered into any hedging programs to mitigate the risk of adverse price fluctuations; however certain 
of our term supply agreements contain price collars, which typically limit the percentage increase or decrease in prices 
for our products during any given year.

Volatile Energy and Fuel Costs

The volatile cost of energy is an important issue affecting our production costs, primarily in relation to our iron 
ore operations.  Our consolidated U.S. Iron Ore mining ventures consumed approximately 18.6 million MMBtu’s of natural 
gas at an average delivered price of $3.52 per MMBtu inclusive of the natural gas hedge impact or $3.36 per MMBtu net 
of the natural gas hedge impact during 2015.  Additionally, our consolidated U.S. Iron Ore mining ventures consumed 
approximately 23.0 million gallons of diesel fuel at an average delivered price of $1.96 per gallon inclusive of the diesel 
fuel hedge impact or $1.90 per gallon net of the diesel fuel hedge impact during 2015.  Consumption of diesel fuel by 
our Asia Pacific operations was approximately 10.0 million gallons at an average delivered price of $1.86 per gallon for 
the same period. 

73

 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

In  the  ordinary  course  of  business,  there  may  also  be  increases  in  electrical  costs  at  our  U.S.  mine  sites. 
Specifically, our Tilden and Empire mines in Michigan have entered into large curtailable special contracts with Wisconsin 
Electric Power Company.  Charges under those special contracts are subject to a power supply cost recovery mechanism 
that is based on variations in the utility's actual fuel and purchase power expenses.

Our  strategy  to  address  increasing  energy  rates  includes  improving  efficiency  in  energy  usage,  identifying 
alternative providers and utilizing the lowest cost alternative fuels.  An energy hedging program has been implemented 
in order to manage the price risk of diesel and natural gas at our U.S. Iron Ore mines during the winter months of 2016. 
This program affects the period of January through March of 2016.  We will continue to monitor relevant energy markets 
for risk mitigation opportunities and may make additional forward purchases or employ other hedging instruments in the 
future as warranted and deemed appropriate by management.  Assuming we do not enter into further hedging activity 
in  the  near  term,  a  10  percent  change  in  electrical,  natural  gas  and  diesel  fuel  prices  would  result  in  a  change  of 
approximately $8.8 million in our annual fuel and energy cost based on expected consumption for 2016.

Foreign Currency Exchange Rate Risk

We are subject to changes in foreign currency exchange rates as a result of our operations in Australia, which 
could  impact  our  financial  condition.    With  respect  to Australia,  foreign  exchange  risk  arises  from  our  exposure  to 
fluctuations  in  foreign  currency  exchange  rates  because  our  reporting  currency  is  the  U.S.  dollar,  but  the  functional 
currency of our Asia Pacific operations is the Australian dollar.  Our Asia Pacific operations receive funds in U.S. currency 
for their iron ore sales and incur costs in Australian currency.

At December 31, 2015, we had no outstanding Australian foreign currency exchange rate contracts for which 
we elected hedge accounting.  Our last outstanding Australian foreign exchange rate contract held as a cash flow hedge 
matured in September 2015.  Due to the uncertainty of 2015 hedge exposures, we have suspended entering into new 
foreign  exchange  rate  contracts.    As  discussed  in  NOTE  1  -  BASIS  OF  PRESENTATION  AND  SIGNIFICANT 
ACCOUNTING POLICIES, we have waived compliance with our current derivative financial instruments and hedging 
activities policy through December 31, 2016.  In the future, we may enter into additional hedging instruments as needed 
in order to further hedge our exposure to changes in foreign currency exchange rates.  Refer to NOTE 13 - DERIVATIVE 
INSTRUMENTS AND HEDGING ACTIVITIES for further information.

Interest Rate Risk

Interest payable on our senior notes is at fixed rates.  Interest payable under our ABL Facility is at a variable 
rate based upon the base rate plus the base rate margin depending on the excess availability.  As of December 31, 2015, 
we had no amounts drawn on the ABL Facility. 

The interest rate payable on the $500.0 million senior notes due in 2018 may be subject to adjustments from 
time to time if either Moody's or S&P or, in either case, any Substitute Rating Agency thereof downgrades (or subsequently 
upgrades) the debt rating assigned to the notes.  In no event shall (1) the interest rate for the notes be reduced to below 
the interest rate payable on the notes on the date of the initial issuance of notes or (2) the total increase in the interest 
rate on the notes exceed 2.00 percent above the interest rate payable on the notes on the date of the initial issuance of 
notes.  Throughout 2014, the interest rate payable on the $500.0 million senior notes due in 2018 was increased from 
3.95 percent ultimately to 5.70 percent based on Substitute Rating Agency downgrades throughout the year.  During the 
first quarter of 2015, subsequent to a downgrade, the interest rate was further increased to 5.95 percent.  This maximum 
rate increase of 2.00 percent has resulted in an additional interest expense of $6.2 million per annum based upon the 
$311.2 million principal balance outstanding as of December 31, 2015. 

Supply Concentration Risks

Many of our mines are dependent on one source each of electric power and natural gas.  A significant interruption 
or  change  in  service  or  rates  from  our  energy  suppliers  could  impact  materially  our  production  costs,  margins  and 
profitability.

Outlook 

We provide full-year expected revenues-per-ton ranges based on different assumptions of seaborne iron ore 
prices.  We indicated that each different pricing assumption holds all other assumptions constant, including customer 
mix, as well as industrial commodity prices, freight rates, energy prices, production input costs and/or hot-band steel 
prices (all factors contained in certain of our supply agreements). 

The U.S. Iron Ore table further assumes full-year hot-band steel pricing of approximately $450 per short ton.  
We note that this estimate is based on our customer's realized prices and not an index or spot market price.  In 2015,

the customer's realized price was approximately $40 per ton higher than the U.S. Domestic Midwest Hot Rolled Coil 
Steel Index.  In terms of sensitivity, for every $50 per ton change in the customer's hot-rolled steel prices, our U.S. Iron 
Ore revenue realizations per ton would be expected to change by $2.25 if steel prices increase, and $1.75 if steel prices 
decrease.

U.S. Iron Ore Outlook (Long Tons)

For 2016, we expect full-year sales volume of approximately 17.5 million tons from our U.S. Iron Ore business.  
In order to reduce pellet inventory levels and generate cash flow from working capital, we currently plan to produce 
approximately 16 million tons of iron ore pellets during 2016.

Our full-year 2016 U.S. Iron Ore cash production cost per ton expectation is $50 - $55.  Our cash cost of goods 
sold per ton expectation is $55 - $60, representing a reduction of $5 from the previously disclosed 2016 cash costs of 
goods sold per ton expectation of $60 - $65.

We anticipate depreciation, depletion and amortization to be approximately $7 per ton for full-year 2016.

Labor Update

We remain in active negotiations with the United Steelworkers and are committed to reaching a fair and equitable 
agreement.  The current contract has been extended by mutual agreement of both parties.  The contract extension 
covers approximately 2,000 USW-represented workers at our Empire and Tilden mines in Michigan, and our United 
Taconite and Hibbing Taconite mines in Minnesota. 

Asia Pacific Iron Ore Outlook (Metric Tons, F.O.B. the port)

Our full-year 2016 Asia Pacific Iron Ore expected sales and production volume is approximately 11.5 million 

tons.  The product mix is expected to contain 50 percent lump and 50 percent fines. 

Based on a full-year average exchange rate of $0.69 U.S. Dollar to Australian Dollar, we are expecting a full-
year 2016 Asia Pacific Iron Ore cash production cost per ton of $25 - $30.  Our cash cost of goods sold per ton expectation 
is expected to be $30 - $35.  We indicated that for every $0.01 change in this exchange rate on a full-year basis, our 
cash cost of goods sold is impacted by approximately $6 million.

We anticipate depreciation, depletion and amortization to be approximately $2 per ton for full-year 2016.

SG&A Expenses and Other Expectations

Full-year 2016 SG&A expenses are expected to be approximately $95 million, a $15 million reduction from the 
full-year 2015 expense.  We also note that of the $95 million expectation, approximately $30 million is considered non-
cash.

We expect full-year 2016 interest expense to be approximately $240 million, of which approximately $205 million 
is cash interest.  Consolidated full-year 2016 depreciation, depletion and amortization is expected to be approximately 
$145 million.

Capital Budget Update

We  expect  full-year  2016  capital  expenditures  to  be  $50  million,  a  significant  reduction  compared  to  2015 
expenditures of $83 million.  The reduction is driven by the divestiture of the remaining coal assets as well as spending 
discipline exhibited in the U.S. Iron Ore business.

Recently Issued Accounting Pronouncements

Refer  to  NOTE  1  -  BASIS  OF  PRESENTATION  AND  SIGNIFICANT  ACCOUNTING  POLICIES  of  the 
consolidated financial statements for a description of recent accounting pronouncements, including the respective dates 
of adoption and effects on results of operations and financial condition.

Critical Accounting Estimates

Management's  discussion  and  analysis  of  financial  condition  and  results  of  operations  is  based  on  our 
consolidated  financial  statements,  which  have  been  prepared  in  accordance  with  GAAP.    Preparation  of  financial 
statements requires management to make assumptions, estimates and judgments that affect the reported amounts of 
assets, liabilities, revenues, costs and expenses, and the related disclosures of contingencies.  Management bases its 
estimates on various assumptions and historical experience, which are believed to be reasonable; however, due to the 
inherent nature of estimates, actual results may differ significantly due to changed conditions or assumptions.  On a 
regular basis, management reviews the accounting policies, assumptions, estimates and judgments to ensure that our 
financial statements are fairly presented in accordance with GAAP.  However, because future events and their effects 
cannot be determined with certainty, actual results could differ from our assumptions and estimates, and such differences 
could be material.  Management believes that the following critical accounting estimates and judgments have a significant 
impact on our financial statements.

Revenue Recognition

U.S. Iron Ore and Asia Pacific Iron Ore Provisional Pricing Arrangements 

Most  of  our  U.S.  Iron  Ore  long-term  supply  agreements  are  comprised  of  a  base  price  with  annual  price 
adjustment factors.  The base price is the primary component of the purchase price for each contract.  The inflation-
indexed price adjustment factors are integral to the iron ore supply contracts and vary based on the agreement, but 
typically include adjustments based upon changes in benchmark and international pellet prices and changes in specified 
Producers Price Indices, including those for industrial commodities excluding fuel, cold rolled steel and strip, and fuel 
and  related  products.    The  pricing  adjustments  generally  operate  in  the  same  manner,  with  each  factor  typically 
76

 
 
 
 
 
 
 
 
 
Table of Contents

comprising a portion of the price adjustment, although the weighting of each factor varies based upon the specific terms 
of each agreement.  In most cases, these adjustment factors have not been finalized at the time our product is sold.  In 
these cases, we historically have estimated the adjustment factors at each reporting period based upon the best third-
party information available.  The estimates are then adjusted to actual when the information has been finalized.  

The Producer Price Indices remain an estimated component of the sales price throughout the contract year 
and are estimated each quarter using publicly available forecasts of such indices.  The final indices referenced in certain 
of the U.S. Iron Ore supply contracts typically are not published by the U.S. Department of Labor until the second quarter 
of the subsequent year.  As a result, we record an adjustment for the difference between the fourth quarter estimate 
and the final price in the following year.

Throughout the year, certain of our Asia Pacific Iron Ore customers have contract arrangements in which pricing 
settlements are based upon an average benchmark pricing for future periods.  Most of the future periods are settled 
within three months.  To the extent the particular pricing settlement period is subsequent to the reporting period, we 
estimate the final pricing settlement based upon information available.  Similar to U.S. Iron Ore, the estimates are then 
adjusted to actual when the price settlement period elapses.

Historically, provisional pricing arrangement adjustments have not been material as they have represented a 
minor portion of U.S. and Asia Pacific Iron Ore's respective revenues for each of the three preceding fiscal years ended 
December 31, 2015, 2014 and 2013.

U.S. Iron Ore Customer Supply Agreements

In addition, certain supply agreements with one U.S. Iron Ore customer include provisions for supplemental 
revenue or refunds based on the customer's average annual steel pricing for the year that the product is consumed in 
the customer's blast furnaces.  The supplemental pricing is characterized as a freestanding derivative and is required 
to be accounted for separately once the product is shipped.  The derivative instrument, which is finalized based on a 
future price, is marked to fair value as a revenue adjustment each reporting period until the pellets are consumed and 
the amounts are settled.  The fair value of the instrument is determined using a market approach based on an estimate 
of the annual realized price of hot rolled steel at the steelmaker's facilities, and takes into consideration current market 
conditions and nonperformance risk.  At December 31, 2015, we had a derivative asset of $5.8 million, representing 
the fair value of the pricing factors, based upon the amount of unconsumed tons and an estimated average hot band 
steel price related to the period in which the tons are expected to be consumed in the customer's blast furnace at each 
respective steelmaking facility, subject to final pricing at a future date.  This compares with a derivative asset of $63.2 
million as of December 31, 2014, based upon the amount of unconsumed tons and the related estimated average hot 
band steel price.  

The customer's average annual price is not known at the time of sale and the actual price is received on a 
delayed basis at the end of the year, once the average annual price has been finalized.  As a result, we estimate the 
average price and adjust the estimate to actual in the fourth quarter when the information is provided by the customer 
at the end of each year.  Information used in developing the estimate includes such factors as production and pricing 
information  from  the  customer,  current  spot  prices,  third-party  analyst  forecasts,  publications  and  other  industry 
information.  The accuracy of our estimates typically increases as the year progresses based on additional information 
in the market becoming available and the customer's ability to more accurately determine the average price it will realize 
for the year.  The following represents the historical accuracy of our pricing estimates related to the derivative as well 
as the impact on revenue resulting from the difference between the estimated price and the actual price for each quarter 
during 2015, 2014 and 2013 prior to receiving final information from the customer for tons consumed during each year:

As an example, we estimate that a $75 positive change in the average hot band steel price realized from the 
December 31, 2015 estimated price recorded for the unconsumed tons remaining at year end would cause the fair 
value  of  the derivative  instrument  to increase  by  approximately  $51.9  million.   Additionally,  we  estimate  that  a $75 
negative change in the average hot band steel price realized from the December 31, 2015 estimated price recorded 
for the unconsumed tons remaining at year end would cause the fair value of the derivative instrument to decrease by 
approximately $44.1 million, thereby impacting our consolidated revenues by the same amount.

Mineral Reserves

We regularly evaluate our mineral reserves and update them as required in accordance with SEC Industry 
Guide 7.  The estimated mineral reserves could be affected by future industry conditions, geological conditions and 
ongoing mine planning.  Maintenance of effective production capacity of the mineral reserve could require increases in 
capital  and  development  expenditures.    Generally,  as  mining  operations  progress,  haul  lengths  and  lifts  increase.  
Alternatively, changes in economic conditions or the expected quality of mineral reserves could decrease capacity or 
mineral reserves.  Technological progress could alleviate such factors or increase capacity of mineral reserves.

We use our mineral reserve estimates, combined with our estimated annual production levels, to determine the 
mine closure dates utilized in recording the fair value liability for asset retirement obligations.  Refer to NOTE 11 - 
ENVIRONMENTAL AND MINE CLOSURE OBLIGATIONS, for further information.  Since the liability represents the 
present value of the expected future obligation, a significant change in mineral reserves or mine lives would have a 
substantial effect on the recorded obligation.  We also utilize mineral reserves for evaluating potential impairments of 
mine assets and in determining maximum useful lives utilized to calculate depreciation and amortization of long-lived 
mine assets.  Increases or decreases in mineral reserves or mine lives could significantly affect these items.

Asset Retirement Obligations and Environmental Remediation Costs 

The  accrued  mine  closure  obligations  for  our  active  mining  operations  provide  for  contractual  and  legal 
obligations associated with the eventual closure of the mining operations.  Our obligations are determined based on 
detailed estimates adjusted for factors that a market participant would consider (i.e., inflation, overhead and profit), 
which are escalated at an assumed rate of inflation to the estimated closure dates, and then discounted using the current 
credit-adjusted risk-free interest rate.  The estimate also incorporates incremental increases in the closure cost estimates 
and changes in estimates of mine lives.  The closure date for each location is determined based on the exhaustion date 
of the remaining iron ore reserves, which is dependent on our estimate of mineral reserves.  The estimated obligations 
are particularly sensitive to the impact of changes in mine lives given the difference between the inflation and discount 
rates.  Changes in the base estimates of legal and contractual closure costs due to changes in legal or contractual 
requirements, available technology, inflation, overhead or profit rates also would have a significant impact on the recorded 
obligations. 

We have a formal policy for environmental protection and restoration.  Our obligations for known environmental 
matters at active and closed mining operations and other sites have been recognized based on estimates of the cost 
of investigation and remediation at each site.  If the obligation can only be estimated as a range of possible amounts, 
with no specific amount being more likely, the minimum of the range is accrued.  Management reviews its environmental 
remediation sites quarterly to determine if additional cost adjustments or disclosures are required.  The characteristics 
of environmental remediation obligations, where information concerning the nature and extent of clean-up activities is 
not immediately available and which are subject to changes in regulatory requirements, result in a significant risk of 
increase to the obligations as they mature.  Expected future expenditures are not discounted to present value unless 
the amount and timing of the cash disbursements can be reasonably estimated.  Potential insurance recoveries are not 
recognized until realized.  Refer to NOTE 11 - ENVIRONMENTAL AND MINE CLOSURE OBLIGATIONS, for further 
information.

Income Taxes 

Our income tax expense, deferred tax assets and liabilities and reserves for unrecognized tax benefits reflect 
management's best assessment of estimated future taxes to be paid.  We are subject to income taxes in both the U.S. 
and numerous foreign jurisdictions.  Significant judgments and estimates are required in determining the consolidated 
income tax expense.

Deferred income taxes arise from temporary differences between tax and financial statement recognition of 
revenue and expense.  In evaluating our ability to recover our deferred tax assets, we consider all available positive 
and negative evidence, including scheduled reversals of deferred tax liabilities, projected future taxable income, tax 
planning strategies and recent financial operations.  In projecting future taxable income, we begin with historical results 

78

 
 
 
 
 
 
 
 
 
 
Table of Contents

adjusted for the results of discontinued operations and changes in accounting policies and incorporate assumptions 
including the amount of future state, federal and foreign pretax operating income, the reversal of temporary differences, 
and the implementation of feasible and prudent tax planning strategies.  These assumptions require significant judgment 
about the forecasts of future taxable income and are consistent with the plans and estimates we are using to manage 
the underlying businesses.  In evaluating the objective evidence that historical results provide, we consider three years 
of cumulative operating income (loss).  

At  December 31,  2015  and  2014,  we  had  a  valuation  allowance  of  $3,372.5  million  and  $1,152.3  million, 
respectively, against our deferred tax assets.  Our losses in certain locations in recent periods represented sufficient 
negative evidence to require a full valuation allowance against certain deferred tax assets.  Additionally, significant 
Alternative Minimum tax credits have been generated in recent years.  Sufficient negative evidence suggests that the 
credits will not be realized in the foreseeable future, and a full valuation allowance has been recorded on the deferred 
tax asset.  We intend to maintain a valuation allowance against the deferred tax assets related to these operating losses, 
credits and allowances until sufficient positive evidence exists to support the realization of such assets. 

Changes  in  tax  laws  and  rates  also  could  affect  recorded  deferred  tax  assets  and  liabilities  in  the  future.  
Management is not aware of any such changes that would have a material effect on the Company's results of operations, 
cash flows or financial position.

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax laws 

and regulations in a multitude of jurisdictions across our global operations.

Accounting for uncertainty in income taxes recognized in the financial statements requires that a tax benefit 
from an uncertain tax position be recognized when it is more likely than not that the position will be sustained upon 
examination, including resolutions of any related appeals or litigation processes, based on technical merits.

We recognize tax liabilities in accordance with ASC 740, Income Taxes, and we adjust these liabilities when 
our judgment changes as a result of evaluation of new information not previously available.  Due to the complexity of 
some of these uncertainties, the ultimate resolution may result in payment that is materially different from our current 
estimate of the tax liabilities.  These differences will be reflected as increases or decreases to income tax expense in 
the period in which they are determined.

Valuation of Long-Lived Assets

In assessing the recoverability of our long-lived assets, significant assumptions regarding the estimated future 
cash flows and other factors to determine the fair value of the respective assets must be made, as well as the related 
estimated useful lives.  If these estimates or their related assumptions change in the future as a result of changes in 
strategy or market conditions, we may be required to record impairment charges for these assets in the period such 
determination was made.

We monitor conditions that indicate that the carrying value of an asset or asset group may be impaired.  In 
order to determine if assets have been impaired, assets are grouped and tested at the lowest level for which identifiable, 
independent cash flows are available.  An impairment loss exists when projected undiscounted cash flows are less than 
the carrying value of the assets.  The measurement of the impairment loss to be recognized is based on the difference 
between the fair value and the carrying value of the assets.  Fair value can be determined using a market approach, 
income approach or cost approach.  The impairment analysis and fair value determination can result in substantially 
different outcomes based on critical assumptions and estimates including the quantity and quality of remaining mineral 
reserves, future iron ore prices and production costs. 

During 2015 and 2014, we identified factors that indicated the carrying values of certain asset groups may not 
be recoverable.  Primary factors included the impact of estimated long-term price forecasts that were updated as part 
of management’s long-range planning process.  Updated estimates of long-term prices for all products, specifically the 
Platts 62 percent Fe fines spot price, which particularly affects the Asia Pacific Iron Ore business segment because 
their contracts correlate heavily to world market spot pricing, were lower than prior estimates.  These estimates were 
updated based upon current market conditions, macro-economic factors influencing the balance of supply and demand 
for our products and expectations for future cost and capital expenditure requirements.  Additional factors include our 
CEO, Lourenco Goncalves, appointed by the Board of Directors in early August 2014, and subsequently identified as 
the CODM in accordance with ASC 280, Segment Reporting.  The CODM views Asia Pacific Iron Ore as non-core 
assets and has communicated plans to evaluate the business unit for a change in strategy including possible divestiture.  
These factors, among other considerations utilized in the individual impairment assessment, indicate that the carrying 
value of the respective asset group may not be recoverable, and resulted in an impairment of other long-lived assets 

79

 
 
 
 
 
 
 
 
 
Table of Contents

of $562.0 million for the year ended December 31, 2014.  Although certain factors indicated that the carrying value of 
certain asset groups may not be recoverable during 2015, an assessment was performed and no further impairment 
was indicated.

Refer  to  NOTE  1  -  BASIS  OF  PRESENTATION AND  SIGNIFICANT ACCOUNTING  POLICIES,  NOTE  4  - 
PROPERTY,  PLANT AND  EQUIPMENT  and  NOTE  6  -  FAIR  VALUE  OF  FINANCIAL  INSTRUMENTS  for  further 
information regarding our policy on asset impairment, detail on our remaining PP&E and mineral rights and non-recurring 
fair value measurements.  

Employee Retirement Benefit Obligations 

We offer defined benefit pension plans, defined contribution pension plans and other postretirement benefit 
plans,  primarily  consisting  of  retiree  healthcare  benefits,  to  most  employees  in  North America  as  part  of  a  total 
compensation and benefits program.  We do not have employee retirement benefit obligations at our Asia Pacific Iron 
Ore operations.  The defined benefit pension plans largely are noncontributory and benefits generally are based on 
employees' years of service and average earnings for a defined period prior to retirement, or a minimum formula.

Following is a summary of our U.S. defined benefit pension and OPEB funding and expense for the years 2013 

through 2016:

Assumptions used in determining the benefit obligations and the value of plan assets for defined benefit pension 
plans and postretirement benefit plans (primarily retiree healthcare benefits) that we offer are evaluated periodically by 
management.  Critical assumptions, such as the discount rate used to measure the benefit obligations, the expected 
long-term rate of return on plan assets, the medical care cost trend, and the rate of compensation increase are reviewed 
annually.

The increase in the discount rates in 2015 was driven by the change in bond yields, which were up approximately 

40 basis points compared to the prior year.

Additionally,  on  December 31,  2015,  the  assumed  mortality  improvement  projection  was  changed  from 
generational scale MP-2014 to generational scale MP-2015.  The healthy mortality assumption remains the RP-2014 
mortality tables with blue collar and white collar adjustments made for certain hourly and salaried groups to determine 
the expected life of our plan participants.

Cliffs Natural Resources Inc. and Subsidiaries

Notes to Consolidated Financial Statements

NOTE 1 - BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES

Business Summary

We are a leading mining and natural resources company in the United States.  We are a major supplier of iron 
ore pellets to the North American steel industry from our five iron ore mines and pellet plants located in Michigan and 
Minnesota.  Additionally, Cliffs operates an iron ore mining complex in Western Australia.  Our continuing operations are 
organized according to geography: U.S. Iron Ore and Asia Pacific Iron Ore.

As more fully described in NOTE 14 - DISCONTINUED OPERATIONS, in January 2015, we announced that 
the Bloom Lake Group commenced restructuring proceedings in Montreal, Quebec under the CCAA.  At that time, we 
had suspended Bloom Lake operations and for several months had been exploring options to sell certain of our Canadian 
assets, among other initiatives.  Effective January 27, 2015, following the CCAA filing of the Bloom Lake Group, we 
deconsolidated the Bloom Lake Group and certain other wholly-owned subsidiaries comprising substantially all of our 
Canadian  operations.   Additionally,  on  May  20,  2015,  the  Wabush  Group  commenced  restructuring  proceedings  in 
Montreal, Quebec under the CCAA which resulted in the deconsolidation of the remaining Wabush Group entities that 
were not previously deconsolidated.  The Wabush Group was no longer generating revenues and was not able to meet 
its obligations as they came due.  As a result of this action, the CCAA protections granted to the Bloom Lake Group were 
extended to include the Wabush Group to facilitate the reorganization of each of their businesses and operations.  Financial 
results prior to the respective deconsolidations of the Bloom Lake and Wabush Groups and subsequent expenses directly 
associated  with  the  Canadian  Entities  are  included  in  our  financial  statements  and  classified  within  discontinued 
operations. 

Also, for the majority of 2015, we operated two metallurgical coal operations in Alabama and West Virginia.  In 
December 2015, we completed the sale of these two metallurgical coal operations, which marked our exit from the coal 
business.   As of March 31, 2015, management determined that our North American Coal operating segment met the 
criteria to be classified as held for sale under ASC 205, Presentation of Financial Statements.  As such, all current year 
and historical North American Coal operating segment results are included in our financial statements and classified 
within discontinued operations. Refer to NOTE 14 - DISCONTINUED OPERATIONS for further discussion of the North 
American Coal segment discontinued operations.

Significant Accounting Policies

We  consider  the  following  policies  to  be  beneficial  in  understanding  the  judgments  that  are  involved  in  the 
preparation of our consolidated financial statements and the uncertainties that could impact our financial condition, results 
of operations and cash flows.

Use of Estimates

The preparation of financial statements, in conformity with GAAP, requires management to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities 
at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period.  
The more significant areas requiring the use of management estimates and assumptions related to mineral reserves 
future  realizable  cash  flow;  environmental,  reclamation  and  closure  obligations;  valuation  of  long-lived  assets  and 
investments; valuation of inventory; valuation of post-employment, post-retirement and other employee benefit liabilities; 
valuation of tax assets; reserves for contingencies and litigation; and the fair value of derivative instruments.  Actual 
results  could  differ  from  estimates.    On  an  ongoing  basis,  management  reviews  estimates.    Changes  in  facts  and 
circumstances may alter such estimates and affect the results of operations and financial position in future periods.

Investments in unconsolidated ventures that we have the ability to exercise significant influence over, but not 
control,  are  accounted  for  under  the  equity  method.    The  following  table  presents  the  detail  of  our  investments  in 
unconsolidated ventures and where those investments are classified in the Statements of Consolidated Financial Position 
as of December 31, 2015 and December 31, 2014.  Parentheses indicate a net liability.

At December 31, 2015, no Other equity method investments remain.

Hibbing

Our share of equity income (loss) is eliminated against consolidated product inventory upon production, and 
against Cost of goods sold and operating expenses when sold.  This effectively reduces our cost for our share of the 
mining ventures' production cost, reflecting the cost-based nature of our participation in unconsolidated ventures.

Amapá 

On March 28, 2013, an unknown event caused the Santana port shiploader to collapse into the Amazon River, 
preventing further ship loading by the mine operator, Anglo.  In light of the March 28, 2013 collapse of the Santana port 
shiploader and subsequent evaluation of the effect that this event had on the carrying value of our investment in Amapá 
as of June 30, 2013, we recorded an impairment charge of $67.6 million in the second quarter of 2013.  

On August 28, 2013, we entered into additional agreements to sell our 30 percent interest in Amapá to Anglo for 
nominal cash consideration, plus the right to certain contingent deferred consideration upon the two-year anniversary of 
the closing.  However, no contingent deferred consideration was earned upon the two-year anniversary.  The closing 
was conditional on obtaining certain regulatory approvals and the additional agreement provided Anglo with an option 
to request that we transfer our interest in Amapá directly to Zamin.  Anglo exercised this option and the transfer to Zamin 
was completed in the fourth quarter of 2013.

Noncontrolling Interests

During the fourth quarter of 2013, CQIM’s interest in Bloom Lake increased by an aggregate of 7.8 percent after 
CQIM paid both its own and WISCO’s proportionate shares of the cash call for the first half of 2013.  As a result of our 
cash call payments, CQIM was issued a total of 457,556 new Bloom Lake units, increasing our interest to 82.8 percent

in Bloom Lake and diluting WISCO’s interest to 17.2 percent.  The new unit issuance decreased equity attributable to 
WISCO  by  $314.8  million  for  the  year  ended  December  31,  2013  by  decreasing  WISCO’s  interest  in  Bloom  Lake’s 
accumulated deficit.   We accounted for the increase in ownership as an equity transaction, which resulted in a $314.8 
million  increase  to  equity  attributable  to  Cliffs’  shareholders.    As  discussed  above,  as  of  January  27,  2015,  we 
deconsolidated the Bloom Lake Group following the CCAA filing.   Financial results prior to the deconsolidation of the 
Bloom Lake Group and subsequent expenses directly associated with the Canadian Entities are included in our financial 
statements. See NOTE 14 - DISCONTINUED OPERATIONS for further information.

Cash Equivalents

Cash and cash equivalents include cash on hand and on deposit as well as all short-term securities held for the 
primary purpose of general liquidity.  We consider investments in highly liquid debt instruments with an original maturity 
of three months or less from the date of acquisition to be cash equivalents.  We routinely monitor and evaluate counterparty 
credit risk related to the financial institutions by which our short-term investment securities are held.

Trade Accounts Receivable and Allowance for Doubtful Accounts

Trade accounts receivable are recorded at the invoiced amount and do not bear interest.  The allowance for 
doubtful accounts is our best estimate of the amount of probable credit losses in Cliffs' existing accounts receivable.  We 
establish provisions for losses on accounts receivable when it is probable that all or part of the outstanding balance will 
not be collected.  We regularly review our accounts receivable balances and establish or adjust the allowance as necessary 
using the specific identification method.  The allowance for doubtful accounts was $7.1 million at December 31, 2015. 
There was no allowance for doubtful accounts at December 31, 2014. There was bad debt expense of $7.1 million for 
the year ended December 31, 2015.  There was no bad debt expense for the years ended December 31, 2014 and 2013. 

Inventories

U.S. Iron Ore

U.S.  Iron  Ore  product  inventories  are  stated  at  the  lower  of  cost  or  market.    Cost  of  iron  ore  inventories  is 

determined using the LIFO method.

We had approximately 1.3 million tons and 1.4 million tons of finished goods stored at ports and customer facilities 
on the lower Great Lakes to service customers at December 31, 2015 and 2014, respectively.  We maintain ownership 
of the inventories until title has transferred to the customer, usually when payment is received.  Maintaining ownership 
of the iron ore products at ports on the lower Great Lakes reduces risk of non-payment by customers.

Asia Pacific Iron Ore

Asia Pacific Iron Ore product inventories are stated at the lower of cost or market.  Costs of inventories are being 
valued on a weighted average cost basis.  We maintain ownership of the inventories until title has transferred to the 
customer, which generally is when the product is loaded into the vessel.

Supplies and Other Inventories

Supply inventories include replacement parts, fuel, chemicals and other general supplies, which are expected 
to  be  used  or  consumed  in  normal  operations.    Supply  inventories  also  include  critical  spares.    Critical  spares  are 
replacement parts for equipment that is critical for the continued operation of the mine or processing facilities.

Supply inventories are stated at the lower of cost or market using average cost, less an allowance for obsolete 
and surplus items.  The allowance for obsolete and surplus items was $31.8 million and $16.0 million at December 31, 
2015 and 2014, respectively.

Derivative Financial Instruments and Hedging Activities

We are exposed to certain risks related to the ongoing operations of our business, including those caused by 
changes in commodity prices, interest rates and foreign currency exchange rates.  We have established policies and 
procedures, including the use of certain derivative instruments, to manage such risks, if deemed necessary.

92

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Derivative financial instruments are recognized as either assets or liabilities in the Statements of Consolidated 
Financial Position and measured at fair value.  On the date a derivative instrument is entered into, we generally designate 
a qualifying derivative instrument as a hedge of the variability of cash flows to be received or paid related to a recognized 
asset or liability or forecasted transaction (cash flow hedge).  We formally document all relationships between hedging 
instruments and hedged items, as well as its risk-management objective and strategy for undertaking various hedge 
transactions.   This  process  includes  linking  all  derivatives  that  are  designated  as  cash  flow  hedges  to  specific  firm 
commitments or forecasted transactions.  We also formally assess both at the hedge's inception and on an ongoing 
basis, whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash 
flows of the related hedged items.  When it is determined that a derivative is not highly effective as a hedge or that it has 
ceased to be a highly effective hedge, we discontinue hedge accounting prospectively and record all future changes in 
fair value in the period of the instrument's earnings or losses.

For derivative instruments that have been designated as cash flow hedges, the effective portion of the changes 
in fair value are recorded in accumulated other comprehensive income (loss) and any portion that is ineffective is recorded 
in  current  period  earnings  or  losses.    Amounts  recorded  in  accumulated  other  comprehensive  income  (loss)  are 
reclassified to earnings or losses in the period the underlying hedged transaction affects earnings or when the underlying 
hedged transaction is no longer reasonably possible of occurring.

For derivative instruments that have not been designated as cash flow hedges, changes in fair value are recorded 

in the period of the instrument's earnings or losses. 

According to our global hedge policy, the policy allows for hedging not more than 75 percent, but not less than 
40 percent for up to 12 months and not less than 10 percent for up to 15 months, of forecasted net currency exposures 
that are probable to occur.  Full hedge compliance under the policy has been waived through December 31, 2016.  The 
waiver was a result of the evaluation of the potential risk of being over hedged and the uncertainty of the 2015 and 2016 
currency exposures.  During 2015, we did not enter into any new foreign currency exchange contracts to hedge our 
foreign currency exposure and we do not expect to enter into any during 2016.  In the future, we may enter into additional 
hedging instruments as needed in order to further hedge our exposure to changes in foreign currency exchange rates.

Refer to NOTE 13 - DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES for further information.

Property, Plant and Equipment 

Our properties are stated at the lower of cost less accumulated depreciation or fair value.  Depreciation of plant 
and equipment is computed principally by the straight-line method based on estimated useful lives, not to exceed the 
mine lives.  The Northshore, United Taconite, Empire and Tilden operations use the double-declining balance method 
of depreciation for certain mining equipment.  The Asia Pacific Iron Ore operation uses the production output method for 
certain mining equipment.  Depreciation is provided over the following estimated useful lives:

Capitalized Stripping Costs

During  the  development  phase,  stripping  costs  are  capitalized  as  a  part  of  the  depreciable  cost  of  building, 
developing and constructing a mine.  These capitalized costs are amortized over the productive life of the mine using 
the units of production method.  The production phase does not commence until the removal of more than a de minimis 
amount of saleable mineral material occurs in conjunction with the removal of overburden or waste material for purposes 
of obtaining access to an ore body.  The stripping costs incurred in the production phase of a mine are variable production 
costs included in the costs of the inventory produced (extracted) during the period that the stripping costs are incurred.

Asset Impairment

Long-Lived Tangible and Intangible Assets

We monitor conditions that may affect the carrying value of our long-lived tangible and intangible assets when 
events and  circumstances indicate that the carrying  value of the  asset  groups  may not be recoverable.   In order to 
determine  if  assets  have  been  impaired,  assets  are  grouped  and  tested  at  the  lowest  level  for  which  identifiable, 
independent cash flows are available ("asset group").  An impairment loss exists when projected undiscounted cash 
flows are less than the carrying value of the asset group.  The measurement of the impairment loss to be recognized is 
based on the difference between the fair value and the carrying value of the asset group.  Fair value can be determined 
using a market approach, income approach or cost approach.  

As a result of these assessments during 2015, we recorded no material impairment charges related to long-lived 
tangible or intangible assets at our continuing operations.  During 2014, we recorded a long-lived tangible asset impairment 
charge of $537.8 million and an intangible asset impairment charge of $13.8 million in our Statements of Consolidated 
Operations related to our continuing operations.  There were no long-lived tangible or intangible asset impairments during 
2013 related to our continuing operations.

Fair Value Measurements

Valuation Hierarchy

ASC  820,  Fair  Value  Measurements  and  Disclosures,  establishes  a  three-level  valuation  hierarchy  for 
classification  of  fair  value  measurements.   The  valuation  hierarchy  is  based  upon  the  transparency  of  inputs  to  the 
valuation  of  an  asset  or  liability  as  of  the  measurement  date.    Inputs  refer  broadly  to  the  assumptions  that  market 
participants would use in pricing an asset or liability.  Inputs may be observable or unobservable.  Observable inputs are 
inputs that reflect the assumptions market participants would use in pricing the asset or liability developed based on 
market data obtained from independent sources.  Unobservable inputs are inputs that reflect our own views about the 
assumptions  market  participants  would  use  in  pricing  the  asset  or  liability  developed  based  on  the  best  information 
available in the circumstances.  The three-tier hierarchy of inputs is summarized below:

• 

• 

Level 1 — Valuation is based upon quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 — Valuation is based upon quoted prices for similar assets and liabilities in active markets, or other 
inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the 
financial instrument.

• 

Level 3 — Valuation is based upon other unobservable inputs that are significant to the fair value measurement.

The classification of assets and liabilities within the valuation hierarchy is based upon the lowest level of input 
that is significant to the fair value measurement in its entirety.  Valuation methodologies used for assets and liabilities 
measured at fair value are as follows:

Table of Contents

Cash Equivalents

Where quoted prices are available in an active market, cash equivalents are classified within Level 1 of the 
valuation hierarchy.  Cash equivalents classified in Level 1 at December 31, 2015 and 2014 include money market funds.  
Valuation of these instruments is determined using a market approach and is based upon unadjusted quoted prices for 
identical assets in active markets. 

Derivative Financial Instruments

Derivative financial instruments valued using financial models that use as their basis readily observable market 
parameters  are  classified  within  Level  2  of  the  valuation  hierarchy.    Such  derivative  financial  instruments  include 
substantially all of our foreign currency exchange contracts and derivative financial instruments that are valued based 
upon published pricing settlements realized by other companies in the industry.  Derivative financial instruments that are 
valued based upon models with significant unobservable market parameters and are normally traded less actively, are 
classified within Level 3 of the valuation hierarchy.

Refer  to  NOTE  6  -  FAIR  VALUE  OF  FINANCIAL  INSTRUMENTS  and  NOTE  7  -  PENSIONS AND  OTHER 

POSTRETIREMENT BENEFITS for further information.

Pensions and Other Postretirement Benefits

We  offer  defined  benefit  pension  plans,  defined  contribution  pension  plans  and  other  postretirement  benefit 
plans,  primarily  consisting  of  retiree  healthcare  benefits,  to  most  employees  in  North  America  as  part  of  a  total 
compensation and benefits program.  We do not have employee pension or post-retirement benefit obligations at our 
Asia Pacific Iron Ore operations.

We recognize the funded or unfunded status of our postretirement benefit obligations on our December 31, 2015 
and 2014 Statements of Consolidated Financial Position based on the difference between the market value of plan assets 
and the actuarial present value of our retirement obligations on that date, on a plan-by-plan basis.  If the plan assets 
exceed the retirement obligations, the amount of the surplus is recorded as an asset; if the retirement obligations exceed 
the plan assets, the amount of the underfunded obligations are recorded as a liability.  Year-end balance sheet adjustments 
to postretirement assets and obligations are recorded as Accumulated other comprehensive loss.

The actuarial estimates of the PBO and APBO retirement obligations incorporate various assumptions including 
the discount rates, the rates of increases in compensation, healthcare cost trend rates, mortality, retirement timing and 
employee turnover.  The discount rate is determined based on the prevailing year-end rates for high-grade corporate 
bonds with a duration matching the expected cash flow timing of the benefit payments from the various plans.  The 
remaining  assumptions  are  based  on  our  estimates  of  future  events  by  incorporating  historical  trends  and  future 
expectations.  The amount of net periodic cost that is recorded in the Statements of Consolidated Operations consists 
of several components including service cost, interest cost, expected return on plan assets, and amortization of previously 
unrecognized amounts.  Service cost represents the value of the benefits earned in the current year by the participants.  
Interest cost represents the cost associated with the passage of time.  Certain items, such as plan amendments, gains 
and/or losses resulting from differences between actual and assumed results for demographic and economic factors 
affecting the obligations and assets of the plans, and changes in other assumptions are subject to deferred recognition 
for income and expense purposes.  The expected return on plan assets is determined utilizing the weighted average of 
expected returns for plan asset investments in various asset categories based on historical performance, adjusted for 
current trends.  See NOTE 7 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS for further information.

Asset Retirement Obligations

Asset retirement obligations are recognized when incurred and recorded as liabilities at fair value.  The fair value 
of the liability is determined as the discounted value of the expected future cash flow.  The asset retirement obligation 
is accreted over time through periodic charges to earnings.  In addition, the asset retirement cost is capitalized as part 
of the asset’s carrying value and amortized over the life of the related asset.  Reclamation costs are adjusted periodically 
to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates of 
either the timing or amount of the reclamation costs.  We review, on an annual basis, unless otherwise deemed necessary, 
the asset retirement obligation at each mine site in accordance with the provisions of ASC 410, Asset Retirement and 
Environmental Obligations.  We perform an in-depth evaluation of the liability every three years in addition to routine 
annual assessments.

Table of Contents

Future remediation costs for inactive mines are accrued based on management’s best estimate at the end of 
each period of the costs expected to be incurred at a site.  Such cost estimates include, where applicable, ongoing 
maintenance and monitoring costs.  Changes in estimates at inactive mines are reflected in earnings in the period an 
estimate is revised.  See NOTE 11 - ENVIRONMENTAL AND MINE CLOSURE OBLIGATIONS for further information.

Environmental Remediation Costs

We have a formal policy for environmental protection and restoration.  Our mining and exploration activities are 
subject to various laws and regulations governing protection of the environment.  We conduct our operations to protect 
the public health and environment and believe our operations are in compliance with applicable laws and regulations in 
all material respects.  Our environmental liabilities, including obligations for known environmental remediation exposures 
at active and closed mining operations and other sites, have been recognized based on the estimated cost of investigation 
and remediation at each site.  If the cost only can be estimated as a range of possible amounts with no point in the range 
being more likely, the minimum of the range is accrued.  Future expenditures are not discounted unless the amount and 
timing of the cash disbursements reasonably can be estimated.  It is possible that additional environmental obligations 
could be incurred, the extent of which cannot be assessed.  Potential insurance recoveries have not been reflected in 
the determination of the liabilities.  See NOTE 11 - ENVIRONMENTAL AND MINE CLOSURE OBLIGATIONS for further 
information.

Revenue Recognition

We sell our products pursuant to comprehensive supply agreements negotiated and executed with our customers.  
Revenue is recognized from a sale when persuasive evidence of an arrangement exists, the price is fixed or determinable, 
the  product  is  delivered  in  accordance  with  F.O.B.  terms,  title  and  risk  of  loss  have  transferred  to  the  customer  in 
accordance with the specified provisions of each supply agreement and collection of the sales price reasonably is assured.  
Our U.S. Iron Ore and Asia Pacific Iron Ore supply agreements provide that title and risk of loss transfer to the customer 
either upon loading of the vessel, shipment or, as is the case with some of our U.S. Iron Ore supply agreements, when 
payment is received.  Under certain term supply agreements, we ship the product to ports on the lower Great Lakes or 
to the customers’ facilities prior to the transfer of title.  Our rationale for shipping iron ore products to certain customers 
and retaining title until payment is received for these products is to minimize credit risk exposure.

Iron ore sales are recorded at a sales price specified in the relevant supply agreements resulting in revenue and 
a receivable at the time of sale.  Upon revenue recognition for provisionally priced sales, a freestanding derivative is 
created for the difference between the sales price used and expected future settlement price.  The derivative, which does 
not  qualify  for  hedge  accounting,  is  adjusted  to  fair  value  through  Product  revenues  as  a  revenue  adjustment  each 
reporting period based upon current market data and forward-looking estimates determined by management until the 
final sales price is determined.  The principal risks associated with recognition of sales on a provisional basis include 
iron ore price fluctuations between the date initially recorded and the date of final settlement.  For revenue recognition, 
we estimate the future settlement rate; however, if significant changes in iron ore prices occur between the provisional 
pricing date and the final settlement date, we might be required to either return a portion of the sales proceeds received 
or bill for the additional sales proceeds due based on the provisional sales price.  Refer to NOTE 13 - DERIVATIVE 
INSTRUMENTS AND HEDGING ACTIVITIES for further information.

In addition, certain supply agreements with one customer include provisions for supplemental revenue or refunds 
based on the customer’s annual steel pricing for the year the product is consumed in the customer’s blast furnaces.  We 
account for this provision as a free standing derivative instrument at the time of sale and record this provision at fair 
value until the year the product is consumed and the amounts are settled as an adjustment to revenue.  Refer to NOTE 
13 - DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES for further information.

Revenue from product sales also includes reimbursement for freight charges paid on behalf of customers and 
freight costs to move product from the port of Esperance to ports in China, which are included in Freight and venture 
partners' cost reimbursements separate from Product revenues.  Revenue is recognized for the expected reimbursement 
of services when the services are performed.

96

 
 
 
 
 
 
 
 
Table of Contents

Deferred Revenue

The terms of one of our U.S. Iron Ore pellet supply agreements required supplemental payments to be paid by 
the customer during the period 2009 through 2012, with the option to defer a portion of the 2009 monthly amount in 
exchange for interest payments until the deferred amount was repaid in 2013.  Installment amounts received under this 
arrangement in excess of sales are classified as deferred revenue in the Statements of Consolidated Financial Position 
upon receipt of payment.  Revenue is recognized over the life of the supply agreement, which extends until 2022, in 
equal annual installments.  As of December 31, 2015 and 2014, installment amounts received in excess of sales totaled 
$89.9 million and $102.8 million, respectively.  As of December 31, 2015, deferred revenue of $12.8 million was recorded 
in Other current liabilities and $77.1 million was recorded as long term in Other liabilities in the Statements of Consolidated 
Financial Position.  As of December 31, 2014, deferred revenue of $12.8 million was recorded in Other current liabilities 
and $90.0 million was recorded as long term in Other liabilities in the Statements of Consolidated Financial Position.  

In  2014,  due  to  the  payment  terms  and  the  timing  of  cash  receipts  near  year-end,  cash  receipts  exceeded 
shipments. The shipments were completed early in the subsequent years. We considered whether revenue should be 
recognized  on  these  sales  under  the  “bill  and  hold”  guidance  provided  by  the  SEC  Staff;  however,  based  upon  the 
assessment  performed,  revenue  recognition  on  these  transactions  totaling  $29.3  million  was  deferred  on  the 
December 31, 2014  Statements of Consolidated Financial Position.  

Cost of Goods Sold

Cost of goods sold and operating expenses represents all direct and indirect costs and expenses applicable to 
the sales and revenues of our mining operations.  Operating expenses primarily represent the portion of the Tilden mining 
venture costs for which we do not own; that is, the costs attributable to the share of the mine’s production owned by the 
other joint venture partner in the Tilden mine.  The mining venture functions as a captive cost company; it supplies product 
only to its owners effectively for the cost of production.  Accordingly, the noncontrolling interests’ revenue amounts are 
stated at cost of production and are offset by an equal amount included in Cost of goods sold and operating expenses 
resulting  in  no  sales  margin  reflected  for  the  noncontrolling  partner  participant.   As  we  are  responsible  for  product 
fulfillment, we act as a principal in the transaction and, accordingly, record revenue under these arrangements on a gross 
basis.

The  following  table  is  a  summary  of  reimbursements  in  our  U.S.  Iron  Ore  operations  for  the  years  ended

31, 2015 and 2014, respectively.  There was no freight for the year ended December 31, 2013.  

Where we have joint ownership of a mine, our contracts entitle us to receive royalties and/or management fees, 

which we earn as the pellets are produced.  

Repairs and Maintenance

Repairs, maintenance and replacement of components are expensed as incurred.  The cost of major equipment 
overhauls  is  capitalized  and  depreciated  over  the  estimated  useful  life,  which  is  the  period  until  the  next  scheduled 
overhaul, generally five years.  All other planned and unplanned repairs and maintenance costs are expensed when 
incurred.

Share-Based Compensation

The fair value of each performance share grant is estimated on the date of grant using a Monte Carlo simulation 
to forecast relative TSR performance.  Consistent with the guidelines of ASC 718, Stock Compensation, a correlation 
matrix of historic and projected stock prices was developed for both the Company and its predetermined peer group of 
mining and metals companies.  The fair value assumes that performance goals will be achieved. 

The expected term of the grant represents the time from the grant date to the end of the service period for each 
of the three plan-year agreements.  We estimated the volatility of our common shares and that of the peer group of mining 
and metals companies using daily price intervals for all companies.  The risk-free interest rate is the rate at the grant 
date on zero-coupon government bonds, with a term commensurate with the remaining life of the performance plans.

The fair value of stock options is estimated on the date of grant using a Black-Scholes model using the grant 
date price of our common shares and option exercise price, and assumptions regarding the option’s expected term, the 
volatility of our common shares, the risk-free interest rate, and the dividend yield over the option’s expected term.

Upon vesting of share-based compensation awards, we issue shares from treasury stock before issuing new 

shares.

Refer to NOTE 8 - STOCK COMPENSATION PLANS for additional information.

Income Taxes

Income taxes are based on income for financial reporting purposes, calculated using tax rates by jurisdiction, 
and reflect a current tax liability or asset for the estimated taxes payable or recoverable on the current year tax return 
and expected annual changes in deferred taxes.  Any interest or penalties on income tax are recognized as a component 
of income tax expense.

We account for income taxes under the asset and liability method, which requires the recognition of deferred 
tax assets and liabilities for the expected future tax consequences of events that have been included in the financial 
statements.  Under this method, deferred tax assets and liabilities are determined based on the differences between the 
financial  statement  and  tax  basis  of  assets  and  liabilities  using  enacted  tax  rates  in  effect  for  the  year  in  which  the 
differences are expected to reverse.  The effect of a change in tax rates on deferred tax assets and liabilities is recognized 
in income in the period that includes the enactment date.

We record net deferred tax assets to the extent we believe these assets will more likely than not be realized.  In 
making such determination, we consider all available positive and negative evidence, including scheduled reversals of 
deferred tax liabilities, projected future taxable income, tax planning strategies and recent financial results of operations.

Accounting for uncertainty in income taxes recognized in the financial statements requires that a tax benefit from 
an uncertain tax position be recognized when it is more likely than not that the position will be sustained upon examination, 
including resolutions of any related appeals or litigation processes, based on technical merits.  

See NOTE 9 - INCOME TAXES for further information.

Discontinued Operations

In April 2014, the FASB issued ASU 2014-08, Reporting Discontinued Operations and Disclosures of Disposals 
of Components of an Entity, which changes the criteria for reporting discontinued operations and requires additional 
disclosures about discontinued operations.  The standard requires that an entity report as a discontinued operation only 
a disposal that represents a strategic shift in operations that has a major effect on its operations and financial results.  
ASU 2014-08 is effective prospectively for new disposals that occur within annual periods beginning on or after December 
15, 2014.  Early adoption was permitted and we adopted ASU 2014-08 during the three months ended December 31, 
2014.

North American Coal Operations

 As we execute our strategy to focus on strengthening our U.S. Iron Ore operations, management determined 
as of March 31, 2015 that our North American Coal operating segment met the criteria to be classified as held for sale 
under ASC 205, Presentation of Financial Statements and continued to meet the criteria throughout 2015.  In December 
2015, we completed the sale of our remaining two metallurgical coal operations, Oak Grove and Pinnacle mines, which 
marked our exit from the coal business. Our plan to sell the Oak Grove and Pinnacle mine assets represented a strategic 
shift in our business.  For this reason, our previously reported North American Coal operating segment results for all 
periods, prior to the March 31, 2015 held for sale determination, are classified as discontinued operations. Additionally, 
the results for the remainder of 2015 were reported as discontinued operations. This also includes our CLCC assets, 
which were sold during the fourth quarter of 2014.  Refer to NOTE 14 - DISCONTINUED OPERATIONS for further 
discussion of our discontinued operations.

Canadian Operations

As more fully described in NOTE 14 - DISCONTINUED OPERATIONS, in January 2015, we announced that 
the Bloom Lake Group commenced restructuring proceedings in Montreal, Quebec under the CCAA.  At that time, we 
had suspended Bloom Lake operations and for several months had been exploring options to sell certain of our Canadian 
assets, among other initiatives.  Effective January 27, 2015, following the CCAA filing of the Bloom Lake Group, we 
deconsolidated the Bloom Lake Group and certain other wholly-owned subsidiaries comprising substantially all of our 
Canadian  operations.   Additionally,  on  May  20,  2015,  the  Wabush  Group  commenced  restructuring  proceedings  in 
Montreal, Quebec under the CCAA which resulted in the deconsolidation of the remaining Wabush Group entities that 
were not previously deconsolidated.  The Wabush Group was no longer generating revenues and was not able to meet 
its obligations as they came due.  As a result of this action, the CCAA protections granted to the Bloom Lake Group were 
extended to include the Wabush Group to facilitate the reorganization of each of their businesses and operations.  Our 
Canadian exit represents a strategic shift in our business.  For this reason, our previously reported Eastern Canadian 
Iron Ore and Ferroalloys operating segment results for all periods prior to the respective deconsolidations as well as 
costs to exit are classified as discontinued operations.

Foreign Currency

Our financial statements are prepared with the U.S. dollar as the reporting currency.  The functional currency of 
our Australian subsidiaries is the Australian dollar.  The functional currency of all other international subsidiaries is the 
U.S. dollar.  The financial statements of international subsidiaries are translated into U.S. dollars using the exchange 
rate at each balance sheet date for assets and liabilities and a weighted average exchange rate for each period for 
revenues, expenses, gains and losses.  Where the local currency is the functional currency, translation adjustments are 
recorded  as  Accumulated  other  comprehensive  loss.    Income  taxes  generally  are  not  provided  for  foreign  currency 
translation adjustments.  To the extent that monetary assets and liabilities, inclusive of intercompany notes, are recorded 
in a currency other than the functional currency, these amounts are remeasured each reporting period, with the resulting 
gain or loss being recorded in the Statements of Consolidated Operations.  Transaction gains and losses resulting from 
remeasurement of short-term intercompany loans are included in Miscellaneous - net in our Statements of Consolidated 
Operations.  For the year ended December 31, 2015, net gains of $16.3 million related to the impact of transaction gains 
and losses resulting from remeasurement.  Of these amounts, for the year ended December 31, 2015, gains of $11.5 
million and $1.5 million resulted from remeasurement of short-term intercompany loans and cash and cash equivalents, 
respectively.  For the year ended December 31, 2014, net gains of $29.0 million related to the impact of transaction gains 
and losses resulting from remeasurement. Of these amounts, for the year ended December 31, 2014, gains of $19.7 
million and $10.6 million, resulted from remeasurement of short-term intercompany loans and cash and cash equivalents, 
respectively.  For the year ended December 31, 2013, net gains of $53.2 million related to the impact of transaction gains 
and losses resulting from remeasurement. Of these amounts, for the year ended December 31, 2013, gains of $33.0 
million and $20.4 million, resulted from remeasurement of short-term intercompany loans and cash and cash equivalents, 
respectively.

Earnings Per Share

We  present  both  basic  and  diluted  earnings  per  share  amounts  for  continuing  operations  and  discontinued 
operations.  Basic earnings per share amounts are calculated by dividing Net Income (Loss) from Continuing Operations 
Attributable to Cliffs Shareholders less any paid or declared but unpaid dividends on our depositary shares by the weighted 
average number of common shares outstanding during the period presented.  Diluted earnings per share amounts are 
calculated by dividing Net Income (Loss) from Continuing Operations Attributable to Cliffs Shareholders by the weighted 
average number of common shares, common share equivalents under stock plans using the treasury stock method and 
the number of common shares that would be issued under an assumed conversion of our outstanding depositary shares,

Table of Contents

each representing a 1/40th interest in a share of our Series A Mandatory Convertible Preferred Stock, Class A, under 
the if-converted method.  Our outstanding depositary shares are convertible into common shares based on the volume 
weighted average of closing prices of our common shares over the 20 consecutive trading day period ending on the third 
day  immediately  preceding  the  end  of  the  reporting  period.    Common  share  equivalents  are  excluded  from  EPS 
computations in the periods in which they have an anti-dilutive effect.  See NOTE 19 - EARNINGS PER SHARE for 
further information.

Recent Accounting Pronouncements

Issued and Not Effective

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory, which specifies that an 
entity should measure inventory at the lower of cost and net realizable value.  Net realizable value is the estimated selling 
price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation.  
The new standard does not apply to inventory that is measured using LIFO; therefore, it is not applicable to our U.S. Iron 
Ore inventory values, but does apply to our Asia Pacific Iron Ore inventories which are valued using the average cost 
method.  The update is effective for financial statement periods beginning after December 15, 2016, including interim 
periods within those fiscal years.  The amendments in ASU 2015-11 should be applied prospectively with earlier application 
permitted as of the beginning of an interim or annual reporting period.  We do not expect the adoption of this pronouncement 
to have an impact on our financial statements and related disclosures.

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties About an Entity's Ability to Continue 
as a Going Concern.  ASU 2014-15 will explicitly require management to assess an entity's ability to continue as a going 
concern,  and  to  provide  related  footnote  disclosure  in  certain  circumstances.   ASU  2014-15  is  intended  to  define 
management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going 
concern  and  to  provide  related  footnote  disclosures.    Specifically, ASU  2014-15  provides  a  definition  of  the  term 
"substantial doubt" and requires an assessment for a period of one year after the date that the financial statements are 
issued (or available to be issued).  It also requires certain disclosures when substantial doubt is alleviated as a result of 
consideration of management’s plans and requires an express statement and other disclosures when substantial doubt 
is not alleviated.  The new standard will be effective for all entities in the first annual period ending after December 15, 
2016 and for annual periods and interim periods thereafter.  Earlier adoption is permitted.  We are currently evaluating 
the impact the adoption of the guidance will have on the Statements of Consolidated Financial Position, Statements of 
Consolidated Operations or Statements of Consolidated Cash Flows. 

In  May  2014,  the  FASB  issued ASU  2014-09,  Revenues  from  Contracts  with  Customers.  The  new  revenue 
guidance broadly replaces the revenue guidance provided throughout the Codification.  The core principle of the revenue 
guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers 
in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or 
services.  To achieve that core principle, an entity should apply the following steps: (1) identify the contract(s) with a 
customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the 
transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) the entity satisfies 
a performance obligation.  The new revenue guidance also requires the capitalization of certain contract acquisition 
costs.  Reporting entities must prepare new disclosures providing qualitative and quantitative information on the nature, 
amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers.  New disclosures also 
include qualitative and quantitative information on significant judgments, changes in judgments, and contract acquisition 
assets.  At issuance, ASU 2014-09 was effective starting in 2017 for calendar-year public entities, and interim periods 
within that year.  In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers: Deferral of 
the Effective Date, which defers the adoption of ASU 2014-09 to annual reporting periods beginning after December 15, 
2017, including interim reporting periods within that reporting period.  Earlier application is permitted only as of annual 
reporting periods beginning after December 15, 2016, including interim reporting periods within that reporting period.  
We  are  still  evaluating  the  impact  of  the  updated  guidance  on  the  Statements  of  Consolidated  Financial  Position, 
Statements of Consolidated Operations or Statements of Consolidated Cash Flows.

Table of Contents

Issued and Adopted

In October 2015, the FASB issued ASU 2015-17, Balance Sheet Classification of Deferred Taxes. This update 
simplifies the presentation of deferred income taxes, by requiring that deferred tax liabilities and assets be classified as 
non-current in a classified statement of financial position. This update is effective for financial statements issued for 
annual periods beginning after December 15, 2016, and interim periods within those annual periods; however, early 
adoption is permitted.  This guidance can also be applied either prospectively to all deferred tax liabilities and assets or 
retrospectively to all periods presented.  We adopted the guidance during the period ended December 31, 2015 and 
have applied this amended accounting guidance to our deferred tax liabilities and assets for all periods presented.  The 
adoption  of ASU  2015-17  did  not  have  an  impact  on  our  Statements  of  Consolidated  Operations  or  Statements  of 
Consolidated Cash Flows.  The impact of the adoption of the guidance resulted in any current deferred tax assets or 
liabilities being reclassified to non-current deferred tax assets or liabilities on the Statements of Consolidated Financial 
Position.  The current deferred tax assets were $23.7 million at December 31, 2014.  The current deferred tax liabilities 
were $4.0 million at December 31, 2014.

In April 2015, the FASB issued ASU 2015-03, Simplifying the Presentation of Debt Issuance Costs, which requires 
that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction 
from the carrying amount of that debt liability, consistent with debt discounts. This ASU requires retrospective adoption 
and will be effective for us beginning in our first quarter of 2016. Early adoption is permitted.  We adopted the guidance 
at December 31, 2015.  The new guidance was applied retrospectively for reporting periods ending on or before December 
31,  2015.   The  adoption  of ASU  2015-03  did  not  have  an  impact  on  our  Statements  of  Consolidated  Operations  or 
Statements of Consolidated Cash Flows.  The impact of the adoption of the guidance resulted in reclassification of the 
unamortized debt issuance costs on the Statements of Consolidated Financial Position from Other non-current assets 
to Long-term debt.  The unamortized debt issuance costs were $29.1 million and $16.8 million at December 31, 2015 
and December 31, 2014, respectively.  

NOTE 2 - SEGMENT REPORTING

Our continuing operations are organized and managed according to geographic location: U.S. Iron Ore and Asia 
Pacific Iron Ore.  The U.S. Iron Ore segment is comprised of our interests in five U.S. mines that provide iron ore to the 
integrated steel industry.  The Asia Pacific Iron Ore segment is located in Western Australia and provides iron ore to the 
seaborne market for Asian steel producers. There were no intersegment product revenues in 2015 or 2014.  Inter-segment 
revenues for 2013 were eliminated in consolidation. 

We have historically evaluated segment performance based on sales margin, defined as revenues less cost of 
goods sold, and operating expenses identifiable to each segment.  Additionally, beginning in the third quarter of 2014, 
concurrent with the change in control on July 29, 2014, management began to evaluate segment performance based 
on EBITDA, defined as net income (loss) before interest, income taxes, depreciation, depletion and amortization, and 
Adjusted EBITDA, defined as EBITDA excluding certain items such as impairment of goodwill and other long-lived assets, 
impacts of discontinued operations, extinguishment of debt, severance and contractor termination costs and other costs 
associated  with  the  change  in  control,  foreign  currency  remeasurement,  certain  supplies  inventory  write-offs,  and 
intersegment  corporate  allocations  of  selling,  general  and  administrative  costs.  Management  believes  that  investors 
benefit from referring to these measures in evaluating operating and financial results, as well as in planning, forecasting 
and analyzing future periods as these financial measures approximate the cash flows associated with the operational 
earnings.

Asia Pacific Iron Ore had long-term work-in-process stockpiles of $6.8 million classified as Other non-current 
assets in the Statements of Consolidated Financial Position at December 31, 2015.   There were no long-term work-in-
process stockpiles as of December 31, 2014.

U.S. Iron Ore

The  excess  of  current  cost  over  LIFO  cost  of  iron  ore  inventories  was  $87.8  million  and  $119.0  million  at 
December 31, 2015 and 2014, respectively.  As of December 31, 2015, the product inventory balance for U.S. Iron Ore 
increased, resulting in a LIFO increment in 2015.  The effect of the inventory build was an increase in Inventories of 
$118.8  million  in  the  Statements  of  Consolidated  Financial  Position  for  the  year  ended  December 31,  2015.   As  of 
December 31, 2014, the product inventory balance for U.S. Iron Ore increased, resulting in a LIFO increment in 2014.  
The effect of the inventory build was an increase in Inventories of $44.8 million in the Statements of Consolidated Financial 
Position for the year ended December 31, 2014.

We recorded depreciation expense of $119.2 million, $173.0 million and $191.5 million in the Statements of 

Consolidated Operations for the years ended December 31, 2015, 2014 and 2013, respectively.

During the second half of 2014, due to lower than previously expected profits as a result of decreased iron ore 
pricing expectations and increased costs, we determined that indicators of impairment with respect to certain of our long-
lived assets or asset groups existed.  Our asset groups generally consist of the assets and liabilities of one or more 

105

 
 
 
 
 
 
 
Table of Contents

mines,  preparation  plants  and  associated  reserves  for  which  the  lowest  level  of  identifiable  cash  flows  largely  are 
independent of cash flows of other mines, preparation plants and associated reserves.

As a result of these assessments during 2014, we determined that the future cash flows associated with our 
Asia Pacific Iron Ore asset group and other asset groups were not sufficient to support the recoverability of the carrying 
value of these productive assets.  Accordingly, during 2014, an other long-lived asset impairment charge of $537.8 million 
was recorded as Impairment of goodwill and other long-lived assets in the Statements of Consolidated Operations related 
to property, plant and equipment.  The fair value estimates were calculated using income and market approaches.  Refer 
to NOTE 6 - FAIR VALUE OF FINANCIAL INSTRUMENTS for further discussion of these impairments and related fair 
value estimates.

Although certain factors indicated that the carrying value of certain asset groups may not be recoverable during 
2015, an assessment was performed and no further impairment was indicated for the year ended December 31, 2015.

The net book value of the land rights and mineral rights as of December 31, 2015 and 2014 is as follows:

respectively.  As discussed above, during 2014 we performed impairment assessments with respect to certain of our 
long-lived assets or asset groups.  As a result of these assessments, we recorded an other long-lived asset impairment 
charge related to mineral rights of $297.2 million associated primarily with our Asia Pacific Iron Ore asset group.

As of December 31, 2014, we had no revolving loans drawn under the revolving credit agreement, which had 
total availability of $1.125 billion as of December 31, 2014.  As of December 31, 2014, the principal amount of 
letter of credit obligations totaled $149.5 million, thereby reducing available borrowing capacity to $975.5 million.

Revolving Credit Facility

As of March 30, 2015, we eliminated the revolving credit agreement which was last amended on January 22, 

2015 (Amendment No. 6).  The revolving credit agreement was replaced with our ABL Facility.

As of December 31, 2014, we were in compliance with all applicable financial covenants related to the revolving 

credit agreement.

ABL Facility

On March 30, 2015, we entered into a new senior secured asset-based revolving credit facility with various 
financial institutions.  The ABL Facility will mature upon the earlier of March 30, 2020 or 60 days prior to the maturity of 
the New First Lien Notes (as defined below) and certain other material debt, and provides for up to $550.0 million in 
borrowings, comprised of (i) a $450.0 million U.S. tranche, including a $250.0 million sublimit for the issuance of letters 
of credit and a $100.0 million sublimit for U.S. swingline loans, and (ii) a $100.0 million Australian tranche, including a 
$50.0  million  sublimit  for  the  issuance  of  letters  of  credit  and  a  $20.0  million  sublimit  for Australian  swingline  loans.  
Availability under both the U.S. tranche and Australian tranche of the ABL Facility is limited to an eligible U.S. borrowing 
base and Australian borrowing base, as applicable, determined by applying customary advance rates to eligible accounts 
receivable, inventory and certain mobile equipment. 

The ABL  Facility  and  certain  bank  products  and  hedge  obligations  are  guaranteed  by  us  and  certain  of  our 
existing wholly-owned U.S. and Australian subsidiaries and are required to be guaranteed by certain of our future U.S. 
and Australian subsidiaries; provided, however, that the obligations of any U.S. entity will not be guaranteed by any 
Australian entity. Amounts outstanding under the ABL Facility will be secured by (i) a first-priority security interest in the 
ABL  Collateral  (as  defined  herein),  including,  in  the  case  of  the Australian  tranche  only, ABL  Collateral  owned  by  a 
borrower or guarantor that is organized under the laws of Australia, and (ii) a third-priority security interest in the Notes 
Collateral (as defined herein). The priority of the security interests in the ABL Collateral and the Notes Collateral of the 
lenders under the ABL Facility and the holders of the First Lien Notes are set forth in intercreditor provisions contained 
in an ABL intercreditor agreement.  

The ABL Collateral generally consists of the following assets: accounts receivable and other rights to payment, 
inventory, as-extracted collateral, investment property, certain general intangibles and commercial tort claims, certain 
mobile equipment, commodities accounts, deposit accounts, securities accounts and other related assets and proceeds 
and products of each of the foregoing.

Borrowings under the ABL Facility bear interest, at our option, at a base rate, an Australian base rate or, if certain 
conditions are met, a LIBOR rate, in each case plus an applicable margin.  The base rate is equal to the greater of the 
federal funds rate plus ½ of 1 percent, the LIBOR rate based on a one-month interest period plus 1 percent and the 
floating rate announced by BAML as its “prime rate.”  The Australian base rate is equal to the LIBOR rate as of 11:00 
a.m. on the first business day of each month for a one-month period.  The LIBOR rate is a per annum fixed rate equal 
to LIBOR with respect to the applicable interest period and amount of LIBOR rate loan requested.

The ABL Facility contains customary representations and warranties and affirmative and negative covenants 
including, among others, covenants regarding the maintenance of certain financial ratios if certain conditions are triggered, 
covenants relating to financial reporting, covenants relating to the payment of dividends on, or purchase or redemption 
of our capital stock, covenants relating to the incurrence or prepayment of certain debt, covenants relating to the incurrence 
of liens or encumbrances, compliance with laws, transactions with affiliates, mergers and sales of all or substantially all 
of our assets and limitations on changes in the nature of our business. 

The ABL Facility provides for customary events of default, including, among other things, the event of nonpayment 
of principal, interest, fees, or other amounts, a representation or warranty proving to have been materially incorrect when 
made, failure to perform or observe certain covenants within a specified period of time, a cross-default to certain material 
indebtedness, the bankruptcy or insolvency of the Company and certain of its subsidiaries, monetary judgment defaults 
of a specified amount, invalidity of any loan documentation, a change of control of the Company, and ERISA defaults 
resulting in liability of a specified amount. In the event of a default by us (beyond any applicable grace or cure period, if 
any), the administrative agent may and, at the direction of the requisite number of lenders, shall declare all amounts 
owing under the ABL Facility immediately due and payable, terminate such lenders’ commitments to make loans under 
the ABL Facility and/or exercise any and all remedies and other rights under the ABL Facility. For certain defaults related 

109

 
 
 
 
 
 
 
 
Table of Contents

to insolvency and receivership, the commitments of the lenders will be automatically terminated and all outstanding loans 
and other amounts will become immediately due and payable.

As of December 31, 2015, we were in compliance with the ABL Facility liquidity requirements and, therefore, the 

springing financial covenant requiring a minimum fixed charge coverage ratio of 1.0 to 1.0 was not applicable.

$540 Million 8.25 percent 2020 Senior Secured First Lien Notes - 2015 Offering

On March 30, 2015, we entered into an indenture among the Company, the guarantors party thereto and U.S. 
Bank National Association, as trustee and notes collateral  agent, relating to our issuance of $540 million aggregate 
principal amount of 8.25 percent Senior First Lien Notes due 2020 (the "First Lien Notes").  The First Lien Notes were 
sold on March 30, 2015 in a private transaction exempt from the registration requirements of the Securities Act.

The First Lien Notes bear interest at a rate of 8.25 percent per annum.  Interest on the First Liens Notes is 
payable semi-annually in arrears on March 31 and September 30 of each year, commencing on September 30, 2015.  
The First Lien Notes mature on March 31, 2020 and are secured senior obligations of the Company.

The First Lien Notes are jointly and severally and fully and unconditionally guaranteed on a senior secured basis 
by substantially all of our material U.S. subsidiaries and are secured (subject in each case to certain exceptions and 
permitted liens) by (i) a first-priority lien on substantially all of our U.S. assets, other than the ABL Collateral (the "Notes 
Collateral"), and (ii) a second-priority lien on the U.S. ABL Collateral, which is junior to a first-priority lien for the benefit 
of the lenders under the ABL Facility.  The First Lien Notes and guarantees are general senior obligations of the Company 
and the applicable guarantor; are effectively senior to all of our unsecured indebtedness, to the extent of the value of 
the collateral; together with other obligations secured equally and ratably with the First Lien Notes, are effectively (i) 
senior to our existing and future ABL obligations, to the extent and value of the Notes Collateral and (ii) senior to our 
obligations under the Second Lien Notes, to the extent and value of the collateral; are effectively subordinated to (i) our 
existing and future ABL obligations, to the extent and value of the ABL Collateral, and (ii) any existing or future indebtedness 
that is secured by liens on assets that do not constitute a part of the collateral, to the extent of the value of such assets; 
will rank equally in right of payment with all existing and future senior indebtedness, and any guarantees thereof; will 
rank equally in priority as to the Notes Collateral with any future debt secured equally and ratably with the First Lien 
Notes incurred after March 30, 2015; rank senior in right of payment to all existing and future subordinated indebtedness; 
and structurally subordinated to all existing and future indebtedness and other liabilities of our subsidiaries that do not 
guarantee the First Lien Notes.  The relative priority of the liens securing our First Lien Notes obligations and Second 
Lien Notes obligations compared to the liens securing our obligations under the ABL Facility and certain other matters 
relating to the administration of security interests are set forth in intercreditor agreements.

The terms of the First Lien Notes are governed by the First Lien Notes indenture. The First Lien Notes indenture 
contains customary covenants that, among other things, limit our ability to incur secured indebtedness, create liens on 
principal property and the capital stock or debt of a subsidiary that owns a principal property, use proceeds of dispositions 
of collateral, enter into sale and leaseback transactions, merge or consolidate with another company, and transfer or sell 
all or substantially all of our assets. Upon the occurrence of a “change of control triggering event,” as defined in the 
indenture, we are required to offer to repurchase the First Lien Notes at 101 percent of the aggregate principal amount 
thereof, plus any accrued and unpaid interest, if any, to, but excluding, the repurchase date.

We may redeem any of the First Lien Notes beginning on March 31, 2018. The initial redemption price is 108.25 
percent of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. The 
redemption price will decline after 2018 and will be 100 percent of their principal amount, plus accrued interest, beginning 
on June 30, 2019. We may also redeem some or all of the First Lien Notes at any time and from time to time prior to 
March 31, 2018 at a price equal to 100 percent of the principal amount thereof plus a “make-whole” premium, plus 
accrued and unpaid interest, if any, to, but excluding, the redemption date. In addition, at any time and from time to time 
on or prior to March 31, 2018, we may redeem in the aggregate up to 35 percent of the original aggregate principal 
amount of the First Lien Notes (calculated after giving effect to any issuance of additional First Lien Notes) with the net 
cash proceeds of certain equity offerings, at a redemption price of 108.25 percent, plus accrued and unpaid interest, if 
any, to, but excluding, the redemption date, so long as at least 65 percent of the original aggregate principal amount of 
the First Lien Notes (calculated after giving effect to any issuance of additional First Lien Notes) issued under the First 
Lien Notes indenture remain outstanding after each such redemption.

The First Lien Notes indenture contains customary events of default, including failure to make required payments, 
failure to comply with certain agreements or covenants, failure to pay or acceleration of certain other indebtedness, 
certain events of bankruptcy and insolvency, and failure to pay certain judgments. An event of default under the First 
Lien indenture will allow either the trustee or the holders of at least 25 percent in aggregate principal amount of the then-

110

 
 
 
 
 
 
 
Table of Contents

outstanding First Lien Notes issued under such indenture to accelerate, or in certain cases, will automatically cause the 
acceleration of the amounts due under the First Lien Notes.

$544 Million 7.75 percent 2020 Senior Secured Second Lien Notes - 2015 Offering

 On March 30, 2015, we also entered into an indenture among the Company, the guarantors and U.S. Bank 
National Association, as trustee and notes collateral agent, relating to our issuance of $544.2 million aggregate principal 
amount of 7.75 percent second lien senior secured notes due 2020 (the "Second Lien Notes"). The Second Lien Notes 
were issued on March 30, 2015 in exchange offers for certain of our existing senior notes. 

The Second Lien Notes bear interest at a rate of 7.75 percent per annum.  Interest on the Second Lien Notes 
is payable semi-annually in arrears on March 31 and September 30 of each year, commencing on September 30, 2015.  
The Second Lien Notes mature on March 31, 2020 and are secured senior obligations of the Company. 

The Second Lien Notes have substantially similar terms to those of the First Lien Notes except with respect to 
their priority security interest in the collateral.  The Second Lien Notes are jointly and severally and fully and unconditionally 
guaranteed on a senior secured basis by substantially all of our material U.S. subsidiaries and are secured (subject in 
each  case  to  certain  exceptions  and  permitted  liens)  by  (i)  a  second-priority  lien  (junior  to  the  First  Lien  Notes)  on 
substantially all of our U.S. assets, other than the ABL Collateral, and (ii) a third-priority lien (junior to the ABL Facility 
and the First Lien Notes) on the U.S. ABL Collateral. 

The Company may redeem any of the Second Lien Notes beginning on March 31, 2017. The initial redemption 
price is 103.875 percent of their principal amount, plus accrued and unpaid interest, if any, to, but excluding, the redemption 
date. The redemption price will decline each year after March 31, 2017 and will be 100 percent of their principal amount, 
plus accrued interest, beginning on March 31, 2019. The Company may also redeem some or all of the Second Lien 
Notes at any time and from time to time prior to March 31, 2017 at a price equal to 100 percent of the principal amount 
thereof plus a “make-whole” premium, plus accrued and unpaid interest, if any, to, but excluding, the redemption date. 
In addition, at any time and from time to time on or prior to March 31, 2017, the Company may redeem in the aggregate 
up to 35 percent of the original aggregate principal amount of the Second Lien Notes (calculated after giving effect to 
any issuance of additional Second Lien Notes) with the net cash proceeds of certain equity offerings, at a redemption 
price of 107.75 percent, plus accrued and unpaid interest, if any, to, but excluding, the redemption date, so long as at 
least 65 percent of the original aggregate principal amount of the Second Lien Notes (calculated after giving effect to 
any issuance of additional Second Lien Notes) issued under the Second Lien Notes Indenture remain outstanding after 
each such redemption. 

$500 Million Senior Notes — 2012 Offering

On December 6, 2012, we completed a $500 million public offering of senior notes at 3.95 percent due January 
15, 2018.  Interest is fixed and is payable on January 15 and July 15 of each year, beginning on July 15, 2013 until 
maturity.  The senior notes are unsecured obligations and rank equally in right of payment with all our other existing and 
future unsecured and unsubordinated indebtedness.  There are no subsidiary guarantees of the interest and principal 
amounts.

The senior notes may be redeemed any time at our option not less than 30 days nor more than 60 days after 
prior notice is sent to the holders of the applicable series of notes.  The senior notes are redeemable at a redemption 
price equal to the greater of (1) 100 percent of the principal amount of the notes to be redeemed or (2) the sum of the 
present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted 
to the redemption date on a semi-annual basis at the treasury rate plus 50 basis points with respect to the 2018 senior

In addition, if a change of control triggering event occurs with respect to the senior notes, as defined in the 
agreement, we will be required to offer to purchase the notes of the applicable series at a purchase price equal to 101 
percent of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase.

The terms of the senior notes contain certain customary covenants; however, there are no financial covenants.

Interest Rate Adjustment Based on Rating Events 

The interest rate payable on the $500.0 million 3.95 percent senior notes may be subject to adjustments from 
time to time if either Moody's or S&P or, in either case, any Substitute Rating Agency thereof downgrades (or subsequently 
upgrades) the debt rating assigned to the senior notes.  In no event shall (1) the interest rate for the senior notes be 
reduced to below the interest rate payable on the senior notes on the date of the initial issuance of senior notes or (2) 
the total increase in the interest rate on the senior notes exceed 2.00 percent above the interest rate payable on the

senior notes on the date of the initial issuance of senior notes.  During 2014, the interest rate payable on the $500.0 
million 3.95 percent senior notes was increased from 3.95 percent ultimately to 5.70 percent based on Substitute Rating 
Agency downgrades throughout the year.  During the first quarter of 2015, subsequent to a downgrade, the interest rate 
was further increased and is currently at the maximum interest rate of 5.95 percent per annum.

$1 Billion Senior Notes — 2011 Offering

On March 23, 2011 and April 1, 2011, respectively, we completed a $1 billion public offering of senior notes 
consisting of two tranches: a 10-year tranche of $700 million aggregate principal amount at 4.88 percent senior notes 
due April 1, 2021, and a 30-year tranche of $300 million aggregate principal amount at 6.25 percent senior notes due 
October 1,  2040,  of  which  $500  million  aggregate  principal  amount  previously  was  issued  during  September  2010.  
Interest is fixed and is payable on April 1 and October 1 of each year, beginning on October 1, 2011, for both series of 
senior notes until maturity.  The senior notes are unsecured obligations and rank equally in right of payment with all our 
other existing and future unsecured and unsubordinated indebtedness.  There are no subsidiary guarantees of the interest 
and principal amounts.  The net proceeds from the senior notes offering were used to fund a portion of the acquisition 
of Consolidated Thompson and to pay the related fees and expenses.

The senior notes may be redeemed any time at our option not less than 30 days nor more than 60 days after 
prior notice is sent to the holders of the applicable series of notes.  The senior notes are redeemable at a redemption 
price equal to the greater of (1) 100 percent of the principal amount of the notes to be redeemed or (2) the sum of the 
present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted 
to the redemption date on a semi-annual basis at the treasury rate plus 25 basis points with respect to the 2021 senior 
notes and 40 basis points with respect to the 2040 senior notes, plus, in each case, accrued and unpaid interest to the 
date of redemption.  However, if the 2021 senior notes are redeemed on or after the date that is three months prior to 
their maturity date, the 2021 senior notes will be redeemed at a redemption price equal to 100 percent of the principal 
amount of the notes to be redeemed plus accrued and unpaid interest to the date of redemption.

In addition, if a change of control triggering event occurs with respect to the senior notes, as defined in the 
agreement, we will be required to offer to purchase the notes of the applicable series at a purchase price equal to 101 
percent of the principal amount, plus accrued and unpaid interest, if any, to the date of purchase.

The terms of the senior notes contain certain customary covenants; however, there are no financial covenants.

$1 Billion Senior Notes — 2010 Offering

On September 20, 2010, we completed a $1 billion public offering of senior notes consisting of two tranches: a 
10-year tranche of $500 million aggregate principal amount at 4.80 percent due October 1, 2020, and a 30-year tranche 
of $500 million aggregate principal amount at 6.25 percent due October 1, 2040.  Interest is fixed and is payable on 
April 1 and October 1 of each year, beginning on April 1, 2011, for both series of senior notes until maturity.  The senior 
notes are unsecured obligations and rank equally in right of payment with all of our other existing and future senior 
unsecured and unsubordinated indebtedness.  There are no subsidiary guarantees of the interest and principal amounts.

A portion of the net proceeds from the senior notes offering was used on September 22, 2010 to repay $350 
million outstanding under our credit facility.  A portion of the net proceeds was also used for general corporate purposes, 
including funding of capital expenditures and were used to fund a portion of the acquisition of Consolidated Thompson 
and related expenses.

The senior notes may be redeemed any time at our option not less than 30 days nor more than 60 days after 
prior notice is sent to the holders of the applicable series of notes.  The senior notes are redeemable at a redemption 
price equal to the greater of (1) 100 percent of the principal amount of the notes to be redeemed or (2) the sum of the 
present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted 
to the redemption date on a semi-annual basis at the treasury rate plus 35 basis points with respect to the 2020 senior 
notes and 40 basis points with respect to the 2040 senior notes, plus, in each case, accrued and unpaid interest to the 
date of redemption.  In addition, if a change of control triggering event occurs with respect to the notes, we will be required 
to offer to purchase the notes at a purchase price equal to 101 percent of the principal amount, plus accrued and unpaid 
interest to the date of purchase.

$400 Million Senior Notes Offering — 2010 Offering

On March 17, 2010, we completed a $400 million public offering of senior notes due March 15, 2020.  Interest 
at a fixed rate of 5.90 percent is payable on March 15 and September 15 of each year, beginning on September 15, 
2010, until maturity on March 15, 2020.  The senior notes are unsecured obligations and rank equally in right of payment 
with all of our other existing and future senior unsecured and unsubordinated indebtedness.  There are no subsidiary 
guarantees of the interest and principal amounts.

A portion of the net proceeds from the senior notes offering was used on March 31, 2010 to repay our $200 
million term loan under our credit facility, as well as to repay on May 27, 2010 our share of Amapá’s remaining debt 
outstanding of $100.8 million.  In addition, we used the remainder of the net proceeds to help fund the acquisitions of 
Spider and CLCC during the third quarter of 2010.

The senior notes may be redeemed any time at our option not less than 30 days nor more than 60 days after 
prior notice is sent to the holders of the applicable series of notes.  The senior notes are redeemable at a redemption 
price equal to the greater of (1) 100 percent of the principal amount of the notes to be redeemed or (2) the sum of the 
present values of the remaining scheduled payments of principal and interest on the notes to be redeemed, discounted 
to the redemption date on a semi-annual basis, plus accrued and unpaid interest to the date of redemption.  In addition, 
if a change of control triggering event occurs, we will be required to offer to purchase the notes at a purchase price equal 
to 101 percent of the principal amount, plus accrued and unpaid interest to the date of purchase.

The terms of the senior notes contain certain customary covenants; however, there are no financial covenants.

Letters of Credit

We issued standby letters of credit with certain financial institutions in order to support business obligations 
including,  but  not  limited  to,  workers  compensation  and  environmental  obligations.   As  of  December 31,  2015  and 
December 31, 2014, these letter of credit obligations totaled $186.3 million and $149.5 million, respectively.

Financial assets classified in Level 1 at December 31, 2015 include money market funds.  Financial assets 
classified in Level 1 at December 31, 2014 include available-for-sale marketable securities.  The valuation of these 
instruments is based upon unadjusted quoted prices for identical assets in active markets.

The valuation of financial assets and liabilities classified in Level 2 is determined using a market approach 
based upon quoted prices for similar assets and liabilities in active markets, or other inputs that are observable.  Level 
2 securities primarily include derivative financial instruments valued using financial models that use as their basis readily 
observable market parameters.  At December 31, 2015, such derivative financial instruments included our commodity 
hedge contracts.  The fair value of the commodity hedge contracts is based on forward market prices and represents 
the estimated amount we would receive or pay to terminate these agreements at the reporting date, taking into account 
creditworthiness, nonperformance risk and liquidity risks associated with current market conditions.  At December 31, 
2014, such derivative financial instruments included our foreign currency exchange contracts.  The fair value of the 
foreign currency exchange contracts was based on forward market prices and represented the estimated amount we 
would  receive  or  pay  to  terminate  these  agreements  at  the  reporting  date,  taking  into  account  creditworthiness, 
nonperformance risk and liquidity risks associated with current market conditions.

114

 
 
 
Table of Contents

The derivative assets classified within Level 3 at December 31, 2015 and December 31, 2014 primarily relate 
to a freestanding derivative instrument related to certain supply agreements with one of our U.S. Iron Ore customers.  
The agreements include provisions for supplemental revenue or refunds based on the customer’s annual steel pricing 
at the time the product is consumed in the customer’s blast furnaces.  We account for this provision as a derivative 
instrument at the time of sale and adjust this provision to fair value as an adjustment to Product revenues each reporting 
period until the product is consumed and the amounts are settled.  The fair value of the instrument is determined using 
a market approach based on an estimate of the annual realized price of hot-rolled steel at the steelmaker’s facilities, 
and takes into consideration current market conditions and nonperformance risk.

The Level 3 derivative assets and liabilities at December 31, 2015 and December 31, 2014 also consisted of 
derivatives related to certain provisional pricing arrangements with our U.S. Iron Ore and Asia Pacific Iron Ore customers.  
These provisional pricing arrangements specify provisional price calculations, where the pricing mechanisms generally 
are based on market pricing, with the final revenue rate to be based on market inputs at a specified point in time in the 
future, per the terms of the supply agreements.  The difference between the estimated final revenue at the date of sale 
and the estimated final revenue rate is characterized as a derivative and is required to be accounted for separately 
once the revenue has been recognized.  The derivative instrument is adjusted to fair value through Product revenues 
each reporting period based upon current market data and forward-looking estimates provided by management until 
the final revenue rate is determined.

The following table illustrates information about quantitative inputs and assumptions for the derivative assets 

and derivative liabilities categorized in Level 3 of the fair value hierarchy:

The significant unobservable input used in the fair value measurement of the reporting entity’s provisional pricing 
arrangements is management’s estimate of 62 percent Fe fines spot price based upon current market data, including 
historical seasonality and forward-looking estimates determined by management.  Significant increases or decreases 
in this input would result in a significantly higher or lower fair value measurement, respectively.

The significant unobservable input used in the fair value measurement of the reporting entity’s customer supply 
agreements is the future hot-rolled steel price that is estimated based on current market data, analysts' projections, 
projections provided by the customer and forward-looking estimates determined by management.  Significant increases 
or decreases in this input would result in a significantly higher or lower fair value measurement, respectively.

$544.2 Million 7.75% 2020 Second Lien Notes

The  $544.2  million  7.75  percent  Second  Lien  Notes  issued  in  the  exchange  offers  were  recorded  as  an 
extinguishment of debt as the change in debt terms was considered substantial.  As such, the newly issued Second 
Lien Senior Notes were recorded at fair value at the issuance date.  In order to determine the fair value of the Second 
Lien Senior Notes on the date of the exchange, we utilized the median bid-ask spread obtained from various investment 
banks for the exchange date.  The bid-ask spread is indicative of the fair value of the notes on the exchange date.  The 
27.0 percent discount equated to a discount of $147.0 million on the issue value of $544.2 million, or an estimated fair 
value of $397.2 million.

Table of Contents

Non-Financial Assets

During the third and fourth quarter of 2014, we identified factors that indicated the carrying values of the asset 
groups in the chart above may not be recoverable primarily due to long-term price forecasts as part of management’s 
long-range planning process.  Updated estimates of long-term prices for all products, specifically the Platts 62 percent 
Fe fines spot price were lower than prior estimates.  This especially affects the Asia Pacific Iron Ore business segment 
because their contracts correlate heavily to world market spot pricing, which were updated based upon current market 
conditions, macro-economic factors influencing the balance of supply and demand for our products and expectations 
for future cost and capital expenditure requirements.  

Additionally, our CEO, Lourenco Goncalves, was appointed by the Board of Directors in early August 2014 and 
was subsequently identified as the CODM in accordance with ASC 280, Segment Reporting.  Our CODM views Asia 
Pacific Iron Ore as a non-core asset and has communicated plans to evaluate the business unit for a change in strategy 
including  possible  divestiture.    These  factors,  among  other  considerations  utilized  in  the  individual  impairment 
assessments, indicate that the carrying value of the respective asset groups in the chart above and Asia Pacific Iron 
Ore goodwill may not be recoverable.

During the third quarter of 2014, a goodwill impairment charge of $73.5 million was recorded for our Asia Pacific 
Iron  Ore  reporting  segment.    Based  on  our  review  of  the  fair  value  hierarchy,  the  inputs  used  in  these  fair  value 
measurements were considered Level 3 inputs.

We also recorded impairment charges to property, plant and equipment, mineral rights, intangible assets and 
other long-term assets during the second half of 2014 related to our Asia Pacific Iron Ore operating segment, along 
with impairments charged to reporting units within our Other reportable segments.  A detailed break out of the impairment 
charges is shown in the chart above.  The recorded impairment charges reduce the related assets to their estimated 
fair value as we determined that the future cash flows associated with these operations were not sufficient to support 
the  recoverability  of  the  carrying  value  of  these  assets.    Fair  value  was  determined  based  on  management's  best 
estimate within a range of fair values, which is considered a Level 3 input, and resulted in an asset impairment charge 
of $562.0 million.  The Level 3 inputs used to determine fair value included models developed and market inputs obtained 
by management which provided a range of fair value estimates of property, plant and equipment.  Management’s models 
include internally developed long-term future cash flow estimates, capital expenditure and cost estimates, market inputs 
to determine long-term pricing assumptions, discount rates, and foreign exchange rates.

NOTE 7 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS  

We  offer  defined  benefit  pension  plans,  defined  contribution  pension  plans  and  other  postretirement  benefit 
plans,  primarily  consisting  of  retiree  healthcare  benefits,  to  most  employees  in  the  United  States  as  part  of  a  total 
compensation and benefits program.  We do not have employee retirement benefit obligations at our Asia Pacific Iron 
Ore operations.  The defined benefit pension plans largely are noncontributory and benefits generally are based on 
employees’ years of service and average earnings for a defined period prior to retirement or a minimum formula.

The labor agreements we have with the USW at our U.S. Iron Ore operations cover approximately 2,000 USW-
represented  employees  at  our  Empire  and Tilden  mines  in  Michigan  and  our  United Taconite  and  Hibbing  mines  in 
Minnesota, or 81.0 percent of our total U.S. Iron Ore hourly workforce.  This percentage includes the U.S. Iron Ore hourly 
employees that are on lay-off.  

We offer retiree medical coverage to hourly retirees of our USW-represented mines.  The 2012 USW agreement 
set temporary maximum monthly medical premiums for participants who retired prior to January 1, 2015.  These premium 
maximums expired on December 31, 2015 and reverted to increasing premiums based on the terms of the 2012 bargaining 
agreement. The agreements also provide for an OPEB cap that limits the amount of contributions that we have to make 
toward retiree medical insurance coverage for each retiree and spouse of a retiree per calendar year who retired on or 
after January 1, 2015.  The amount of the annual OPEB cap is based upon the gross plan costs we incurred in 2014. 
The OPEB cap applies to employees who retired on or after January 1, 2015 and does not apply to surviving spouses. 

In addition, we currently provide various levels of retirement health care and OPEB to some full-time employees 
who  meet  certain  length  of  service  and  age  requirements  (a  portion  of  which  is  pursuant  to  collective  bargaining 
agreements).  Most plans require retiree contributions and have deductibles, co-pay requirements and benefit limits.  
Most bargaining unit plans require retiree contributions and co-pays for major medical and prescription drug coverage.  
There is a cap on our cost for medical coverage under the salaried plans.  The annual limit applies to each covered 
participant and equals $7,000 for coverage prior to age 65, with the retiree’s participation adjusted based on the age at 
which the retiree’s benefits commence.  Beginning in 2015, Cliffs changed the delivery of the post-65 salaried retiree 

118

 
 
 
 
 
 
 
 
Table of Contents

medical benefit program, including salaried retirees from our Northshore operation, from an employer sponsored plan 
to the combination of an employer subsidy plan and an individual supplemental Medicare insurance plan purchased 
through a Medicare exchange.  This allows the program to take full advantage of available government subsidies and 
more efficient pricing in the Medicare market.  For participants at our Northshore operation, the annual limit ranges from 
$4,020 to $4,500 for coverage prior to age 65.  Covered participants pay an amount for coverage equal to the excess 
of (i) the average cost of coverage for all covered participants, over (ii) the participant’s individual limit, but in no event 
will the participant’s cost be less than 15.0 percent of the average cost of coverage for all covered participants.  For 
Northshore participants, the minimum participant cost is a fixed dollar amount.  We do not provide OPEB for most salaried 
employees hired after January 1, 1993.  Retiree healthcare coverage is provided through programs administered by 
insurance companies whose charges are based on benefits paid.

In December 2003, The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 was enacted.  
This act introduced a prescription drug benefit under Medicare Part D as well as a federal subsidy to sponsors of retiree 
healthcare benefit plans that provide a benefit that at least actuarially is equivalent to Medicare Part D.  Our measures 
of the accumulated postretirement benefit obligation and net periodic postretirement benefit cost as of December 31, 
2004 and for periods thereafter reflect amounts associated with the subsidy.  We elected to adopt the retroactive transition 
method for recognizing the cost reduction in 2004.  

The Pinnacle and Oak Grove mines were sold in December 2015, and the liabilities representing vested benefits 
at the time of the sale remained with Cliffs.  The sale triggered a curtailment event for the Salaried Pension Plan.  Liabilities 
for other postretirement benefits were transferred as part of the sale, and associated adjustments were made to the 
Accumulated other comprehensive loss balances as they pertained to Pinnacle and Oak Grove participants in the Hourly 
OPEB plan.  Accordingly, all amounts shown below include retained obligations of vested employees of the North American 
Coal mines.  Further, all disclosures presented include the annual expense, contributions and obligations associated 
with the retained vested benefits of these participants.

The accumulated benefit obligation for all defined benefit pension plans was $898.9 million and $980.6 million 
at December 31, 2015 and 2014, respectively.  The decrease in the accumulated benefit obligation primarily is a result 
of an increase in the discount rates.

Assumptions

The discount rate for determining PBO is determined  individually  for each plan.  For our pension and other 
postretirement benefit plans, we used a discount rate as of December 31, 2015 of 4.27 percent for Iron Hourly, 4.12 
percent for Salaried, 4.28 percent for Ore Mining and 4.22 percent for SERP, and 4.22 percent for Salaried OPEB, and 
4.32 percent for Hourly OPEB, compared with a discount rate of 3.83 percent as of December 31, 2014.  The discount 
rates are determined by matching the projected cash flows used to determine the PBO and APBO to a projected yield 
curve of 688 Aa graded bonds in the 40th to 90th percentiles.  These bonds are either noncallable or callable with make-
whole provisions.  For the year ended December 31, 2014, bonds in the 10th to 90th percentile were utilized.  The portion 
of the increases in discount rates due to market conditions resulted in decreases to our plan projected benefit obligations 
of approximately $31.5 million and $13.6 million for the pension and other postretirement benefit plans, respectively.  In 
addition, the portion of the increases in discount rates due to the change to the 40th to 90th percentiles measurement 
resulted in decreases to our plan projected benefit obligations of approximately $8.3 million and $2.7 million for the 
pension and other postretirement benefit plans, respectively.

On December 31, 2015, the assumed mortality improvement projection was changed from generational scale 
MP-2014 to generational scale MP-2015. The healthy mortality assumption remains the RP-2014 mortality tables with 
blue collar adjustments for the Iron Hourly and Hourly PRW plans, with white collar adjustments for the SERP and Salaried 
PRW Plan, and without collar adjustments for the Salaried and Ore Mining. The adoption of the new projection scale 
resulted  in  decreases  to  our  projected  benefit  obligations  totaling  approximately  $15.1  million  or  1.5  percent  for  the 
pension plans and $7.9 million or 2 percent for the OPEB plans.

The rates of retirement and termination for certain groups were also updated as a result of a recent experience 

review.

Our financial objectives with respect to our pension and VEBA plan assets are to fully fund the actuarial accrued 
liability for each of the plans, to maximize investment returns within reasonable and prudent levels of risk, and to maintain 
sufficient liquidity to meet benefit obligations on a timely basis.

Our investment objective is to outperform the expected ROA assumption used in the plans’ actuarial reports over 
the life of the plans.  The expected ROA takes into account historical returns and estimated future long-term returns 
based on capital market assumptions applied to the asset allocation strategy.  The expected return is net of investment 
expenses paid by the plans.  In addition, investment performance is monitored on a quarterly basis by benchmarking to 
various indices and metrics for the one-, three- and five-year periods.

The asset allocation strategy is determined through a detailed analysis of assets and liabilities by plan, which 
defines the overall risk that is acceptable with regard to the expected level and variability of portfolio returns, surplus 
(assets compared to liabilities), contributions and pension expense.

The asset allocation review process involves simulating capital market behaviors including global asset class 
performance, inflation and interest rates in order to evaluate various asset allocation scenarios and determine the asset 
mix with the highest likelihood of meeting financial objectives.  The process includes factoring in the current funded status 
and likely future funded status levels of the plans by taking into account expected growth or decline in the contributions 
over time. 

The asset allocation strategy varies by plan.  The following table reflects the actual asset allocations for pension 
and VEBA plan assets as of December 31, 2015 and 2014, as well as the 2016 weighted average target asset allocations 
as of December 31, 2015.  Equity investments include securities in large-cap, mid-cap and small-cap companies located 
in the U.S. and worldwide.  Fixed income investments primarily include corporate bonds and government debt securities.  
Alternative investments include hedge funds, private equity, structured credit and real estate.

Following is a description of the inputs and valuation methodologies used to measure the fair value of our plan 

assets.

Equity Securities

Equity  securities  classified  as  Level  1  investments  include  U.S.  large-,  small-  and  mid-cap  investments  and 
international equity.  These investments are comprised of securities listed on an exchange, market or automated quotation 
system for which quotations are readily available.  The valuation of these securities is determined using a market approach, 
and is based upon unadjusted quoted prices for identical assets in active markets.

124

 
 
 
 
 
Table of Contents

Fixed Income

Fixed income securities classified as Level 1 investments include bonds and government debt securities.  These 
investments are comprised of securities listed on an exchange, market or automated quotation system for which quotations 
are  readily  available.   The  valuation  of  these  securities  is  determined  using  a  market  approach,  and  is  based  upon 
unadjusted quoted prices for identical assets in active markets.  Also included in Fixed Income is a portfolio of U.S. 
Treasury STRIPS, which are zero-coupon bearing fixed income securities backed by the full faith and credit of the U.S. 
government.  The securities sell at a discount to par because there are no incremental coupon payments.  STRIPS are 
not issued directly  by the Treasury, but rather are  created by a  financial  institution, government  securities broker  or 
government securities dealer.  Liquidity on the issue varies depending on various market conditions; however, in general 
the STRIPS market is slightly less liquid than that of the U.S. Treasury Bond market.  The STRIPS are priced daily through 
a bond pricing vendor and are classified as Level 2.

Hedge Funds

Hedge funds are alternative investments comprised of direct or indirect investment in offshore hedge funds with 
an investment objective to achieve an attractive risk-adjusted return with moderate volatility and moderate directional 
market exposure over a full market cycle.  The valuation techniques used to measure fair value attempt to maximize the 
use of observable inputs and minimize the use of unobservable inputs.  Considerable judgment is required to interpret 
the factors used to develop estimates of fair value.  Valuations of the underlying investment funds are obtained and 
reviewed.  The securities that are valued by the funds are interests in the investment funds and not the underlying holdings 
of such investment funds.  Thus, the inputs used to value the investments in each of the underlying funds may differ from 
the inputs used to value the underlying holdings of such funds.

In determining the fair value of a security, the fund managers may consider any information that is deemed 
relevant, which may include one or more of the following factors regarding the portfolio security, if appropriate: type of 
security  or  asset;  cost  at  the  date  of  purchase;  size  of  holding;  last  trade  price;  most  recent  valuation;  fundamental 
analytical data relating to the investment in the security; nature and duration of any restriction on the disposition of the 
security; evaluation of the factors that influence the market in which the security is purchased or sold; financial statements 
of the issuer; discount from market value of unrestricted securities of the same class at the time of purchase; special 
reports prepared by analysts; information as to any transactions or offers with respect to the security; existence of merger 
proposals or tender offers affecting the security; price and extent of public trading in similar securities of the issuer or 
compatible companies and other relevant matters; changes in interest rates; observations from financial institutions; 
domestic  or  foreign  government  actions  or  pronouncements;  other  recent  events;  existence  of  shelf  registration  for 
restricted  securities;  existence  of  any  undertaking  to  register  the  security;  and  other  acceptable  methods  of  valuing 
portfolio securities.

Private Equity Funds

Private equity funds are alternative investments that represent direct or indirect investments in partnerships, 

venture funds or a diversified pool of private investment vehicles (fund of funds).

Investment commitments are made in private equity funds based on an asset allocation strategy, and capital 
calls are made over the life of the funds to fund the commitments.  As of December 31, 2015, remaining commitments 
total $48.1 million for both our pension and other benefits.  Committed amounts are funded from plan assets when capital 
calls are made.  Investment commitments are not pre-funded in reserve accounts.  Refer to the valuation methodologies 
for equity securities above for further information.

The valuation of investments in private equity funds initially is performed by the underlying fund managers.  In 
determining the fair value, the fund managers may consider any information that is deemed relevant, which may include: 
type of security or asset; cost at the date of purchase; size of holding; last trade price; most recent valuation; fundamental 
analytical data relating to the investment in the security; nature and duration of any restriction on the disposition of the 
security; evaluation of the factors that influence the market in which the security is purchased or sold; financial statements 
of the issuer; discount from market value of unrestricted securities of the same class at the time of purchase; special 
reports prepared by analysts; information as to any transactions or offers with respect to the security; existence of merger 
proposals or tender offers affecting the security; price and extent of public trading in similar securities of the issuer or 
compatible companies and other relevant matters; changes in interest rates; observations from financial institutions; 
domestic  or  foreign  government  actions  or  pronouncements;  other  recent  events;  existence  of  shelf  registration  for 
restricted  securities;  existence  of  any  undertaking  to  register  the  security;  and  other  acceptable  methods  of  valuing 
portfolio securities.

Table of Contents

The valuations are obtained from the underlying fund managers, and the valuation methodology and process is 
reviewed for consistent application and adherence to policies.  Considerable judgment is required to interpret the factors 
used to develop estimates of fair value.

Private equity investments are valued quarterly and recorded on a one-quarter lag.  For alternative investment 
values reported on a lag, current market information is reviewed for any material changes in values at the reporting date.  
Capital distributions for the funds do not occur on a regular frequency.  Liquidation of these investments would require 
sale of the partnership interest.

Structured Credit

Structured credit investments are alternative investments comprised of collateralized debt obligations and other 
structured credit investments that are priced based on valuations provided by independent, third-party pricing agents, if 
available.  Such values generally reflect the last reported sales price if the security is actively traded.  The third-party 
pricing agents may also value structured credit investments at an evaluated bid price by employing methodologies that 
utilize actual market transactions, broker-supplied valuations, or other methodologies designed to identify the market 
value of such securities.  Such methodologies generally consider such factors as security prices, yields, maturities, call 
features, ratings and developments relating to specific securities in arriving at valuations.  Securities listed on a securities 
exchange, market or automated quotation system for which quotations are readily available are valued at the last quoted 
sale price on the primary exchange or market on which they are traded.  Debt obligations with remaining maturities of 
60 days or less may be valued at amortized cost, which approximates fair value.

Structured credit investments are valued monthly and recorded on a one-month lag.  For alternative investment 
values reported on a lag, current market information is reviewed for any material changes in values at the reporting date.  
Historically, redemption requests have been considered quarterly, subject to notice of 90 days, although the advisor is 
currently only requiring notice of 65 days.  During the fourth quarter of 2015, a redemption request for tender of $8 million 
was executed in order to bring the portfolio more in line with the target allocation for this asset category.  The tender was 
effective as of December 31, 2015, with the funds targeted for distribution during the first quarter of 2016.       

Real Estate

The real estate portfolio for the pension plans is an alternative investment primarily comprised of two funds with 
strategic categories of real estate investments.  All real estate holdings are appraised externally at least annually, and 
appraisals are conducted by reputable, independent appraisal firms that are members of the Appraisal Institute.  All 
external appraisals are performed in accordance with the Uniform Standards of Professional Appraisal Practices.  The 
property valuations and assumptions of each property are reviewed quarterly by the investment advisor and values are 
adjusted if there has been a significant change in circumstances relating to the property since the last external appraisal.  
The valuation methodology utilized in determining the fair value is consistent with the best practices prevailing within the 
real estate appraisal and real estate investment management industries, including the Real Estate Information Standards, 
and standards promulgated by the National Council of Real Estate Investment Fiduciaries, the National Association of 
Real Estate Investment Fiduciaries, and the National Association of Real Estate Managers.  In addition, the investment 
advisor may cause additional appraisals to be performed.  Two of the funds’ fair values are updated monthly, and there 
is no lag in reported values.  Redemption requests for these two funds are considered on a quarterly basis, subject to 
notice of 45 days.

During 2011, a new real estate fund of funds investment was added for the Empire, Tilden, Hibbing and United 
Taconite VEBA plans as a result of the asset allocation review process.  This fund invests in pooled investment vehicles 
that in turn invest in commercial real estate properties.  Valuations are performed quarterly and financial statements are 
prepared on a semi-annual basis, with annual audited statements.  Asset values for this fund are reported with a one-
quarter lag and current market information is reviewed for any material changes in values at the reporting date.  In most 
cases, values are based on valuations reported by underlying fund managers or other independent third-party sources, 
but the fund has discretion to use other valuation methods, subject to compliance with ERISA.  Valuations are typically 
estimates and subject to upward or downward revision based on each underlying fund’s annual audit.  Withdrawals are 
permitted on the last business day of each quarter subject to a 65-day prior written notice.

Contributions

Annual contributions to the pension plans are made within income tax deductibility restrictions in accordance 
with statutory regulations.  In the event of plan termination, the plan sponsors could be required to fund additional shutdown 
and early retirement obligations that are not included in the pension obligations.  The Company currently has no intention 
to shutdown, terminate or withdraw from any of its employee benefit plans.

Pursuant to the bargaining agreement, benefits can be paid from VEBA trusts that are at least 70 percent funded 
(all VEBA trusts are over 70 percent funded at December 31, 2015).  Funding obligations have been suspended 
as Hibbing's, UTAC's, Tilden's and Empire's share of the value of their respective trust assets have reached 90 
percent of their obligation.

VEBA plans are not subject to minimum regulatory funding requirements.  Amounts contributed are pursuant 

to bargaining agreements.

Contributions by participants to the other benefit plans were $4.0 million for the year ended December 31,

At December 31, 2015, we have outstanding awards under two share-based compensation plans, which are 
described below.  The compensation cost that has been charged against income for those plans was $13.9 million, 
$21.5 million and $19.1 million in 2015, 2014 and 2013, respectively, which primarily was recorded in Selling, general 
and administrative expenses in the Statements of Consolidated Operations.  The total income tax benefit recognized 
in the Statements of Consolidated Operations for share-based compensation arrangements was $7.5 million and $6.7 
million for 2014 and 2013, respectively.  There was no income tax benefit recognized for the year ended December 31, 
2015, due to the full valuation allowance.

Employees’ Plans

The 2015 Equity Plan was approved by our Board of Directors on March 26, 2015 and by our shareholders on 
May 19, 2015.  The 2015 Equity Plan replaced the 2012 Amended Equity Plan. The maximum number of shares that 
may be issued under the 2015 Equity Plan is 12.9 million common shares.  No additional grants were issued from the 
2012 Amended Equity Plan after the date of approval of the 2015 Equity Plan; however, all awards previously granted 
under the 2012 Amended Equity Plan will continue in full force and effect in accordance with the terms of outstanding 
awards.

During the third quarter of 2015, the Compensation Committee approved grants under the 2015 Equity Plan of 
1.5  million  restricted  share  units  to  certain  officers  and  employees  with  a  grant  date  of  September  10,  2015.   The 
restricted  share  units  granted  under  this  award  are  subject  to  continued  employment  through  the  vesting  date  of 
December 15, 2017. 

During the first quarter of 2015, the Compensation Committee approved grants under the 2012 Amended Equity 
Plan to certain officers and employees for the 2015 to 2017 performance period.  Shares granted under the awards 
consisted of 0.9 million performance shares, 0.9 million restricted share units and 0.4 million stock options. 

On February 10, 2014, upon recommendation by the Compensation Committee, our Board of Directors approved 
and adopted, subject to the approval of our shareholders at the 2014 Annual Meeting, the 2012 Amended Equity Plan.  
The principal reason for amending and restating the 2012 Equity Plan was to increase the number of common shares 
available for issuance by 5.0 million common shares.  This amended plan was approved by our shareholders at the 
2014 Annual Meeting held on July 29, 2014.  

Subsequent to our 2014 Annual Meeting of Shareholders, where shareholders elected six new directors, our 
board changed substantially.  Such an event constituted a change in control pursuant to our incentive equity plans and 
applicable award agreements.  As a result, all of the outstanding and unvested equity incentives awarded to participants 
prior to October 2013 became vested.  Accordingly, this resulted in recognizing $11.7 million of additional equity-based 
compensation  expense  in  the  accompanying  financial  statements,  representing  the  remaining  unrecognized 
compensation expense of the awards.  For any equity grants awarded after September 2013, the vesting of all such 
grants will accelerate and pay out in cash only following a participant's qualifying termination of employment associated 
with the change in control and if the common shares are not substituted with a replacement award.  This potential liability 
for additional double-trigger payments for share-based compensation in cash will expire on August 6, 2016.

Performance Shares

The outstanding performance share or unit grants vest over a period of three years and are intended to be paid 
out in common shares or cash in certain circumstances.  Performance is measured on the basis of relative TSR for the 
period and measured against the constituents of the S&P Metals and Mining ETF Index on the last day of trading of 
the relevant performance period.  The final payouts for the outstanding performance period grants will vary from zero 
to 200 percent of the original grant depending on whether and to what extent the Company achieves certain objectives 
and performance goals as established by the Compensation Committee.

For the outstanding performance-based restricted stock units, the award may be earned and settled based 
upon certain VWAP performance for the Company’s common shares, (Threshold VWAP, Target VWAP, or Maximum 
VWAP) for any period of ninety (90) consecutive calendar days during a performance period commencing August 7, 
2014 and ending December 31, 2017.  

Restricted Share Units

The outstanding restricted share units are subject to continued employment, are retention based, will vest in 
equal thirds on each of December 31, 2015, December 31, 2016 and December 31, 2017, and are payable in common 
shares or cash in certain circumstances at a time determined by the Compensation Committee at its discretion. 

Stock Options

The stock options that were granted during the first quarter of 2015 vest on December 31, 2017, subject to 
continued employment through the vesting date, are exercisable at a strike price of $7.70 after the vesting date and 
expire on January 12, 2025.  The stock options that were granted on November 17, 2014 vest in equal thirds on each 
of December 31, 2015, December 31, 2016 and December 31, 2017 subject to continued employment through each 
vesting date, and are exercisable cumulatively at a strike price of $13.83 after each vesting date and expire on November 
17, 2021. 

Employee Stock Purchase Plan

On March 26, 2015, upon recommendation by the Compensation Committee, our Board of Directors approved 
and adopted, subject to the approval of Cliffs' shareholders at the 2015 Annual Meeting, the Cliffs Natural Resources 
Inc. 2015 Employee Stock Purchase Plan.  This plan was approved by our shareholders at the 2015 Annual Meeting 
held May 19, 2015.  10 million common shares have been registered for issuance under this plan and zero common 
shares have been purchased.  We sought shareholder approval of this plan for the purpose of qualifying the reserved 
common shares for special tax treatment under Section 423 of the Internal Revenue Code of 1986, as amended.

Nonemployee Directors 

Equity Grants

During 2015 our nonemployee directors were entitled to receive restricted share awards under the Directors’ 
Plan.  For 2015, nonemployee directors were granted a number of restricted shares, with a value equal to $85,000, 
based on the closing price of our common shares on May 19, 2015, the date of the Company’s 2015 annual meeting 
of shareholders, subject to any deferral election and pursuant to the terms of the Directors’ Plan and an award agreement, 
effective on May 19, 2015.

Table of Contents

At our 2014 annual meeting, the shareholders approved the Directors' Plan which became effective December 
1, 2014.  The Directors’ Plan authorizes us to issue up to 300,000 common shares from time to time to nonemployee 
Directors.  Under the Share Ownership Guidelines in effect for 2015 ("Guidelines"), a Director is required by the end of 
five years from date of election to hold common shares with a market value of at least $250,000.  The Directors’ Plan 
offers the nonemployee Director the opportunity to defer all or a portion of the awards granted. 

Directors receive dividends, if any, on their restricted share awards and may elect that all cash dividends with 
respect to restricted shares be deferred and reinvested in additional common shares. Those additional common shares 
are subject to the same restrictions as the underlying award. Cash dividends not subject to a deferral election will be 
paid to the director without restriction.

The 2008 Directors’ Plan in effect for most of 2014 provided for an Annual Equity Grant ("Equity Grant") to be 
awarded at our annual meeting each year to all nonemployee Directors elected or re-elected by the shareholders and 
a pro-rata amount was awarded to new directors upon their appointment.  The value of the Equity Grant was payable 
in restricted shares with a three-year vesting period from the date of grant.  The closing market price of our common 
shares on October 16, 2014 was divided into the number of common shares remaining available for issuance under 
the 2008 Directors' Plan to determine the number of restricted shares awarded as the Equity Grant.  In 2014, nonemployee 
Directors each received Equity Grants valued at $85,000 which was bifurcated into two tranches since the 2008 Director's 
Plan did not have a sufficient number of shares available for issuance.  The first tranche of the 2014 Equity Grant was 
granted under the 2008 Directors' Plan on October 16, 2014 and valued at $42,500.  The second tranche was granted 
under the Directors' Plan on December 2, 2014 and valued at $42,500. 

For the last three years, Equity Grant shares have been awarded to elected or re-elected nonemployee Directors 

as follows:

Starting in July, 2015, the Governance and Nominating Committee recommended, and the Board adopted, a 
Nonemployee Director Retainer Share Election Program pursuant to which nonemployee directors may elect to receive 
all  or any  portion  of their  annual  retainer  and  any  other  fees  earned  in  cash  in  Cliffs'  common  shares.    Election is 
voluntary and irrevocable for the applicable election period and shares issued under this program must be held for six 
months from the issuance date. The number of shares received each quarter are calculated by dividing the value of 
the quarterly cash retainer amount by the closing market price of the date of payment.

Determination of Fair Value

Performance Shares

The fair value of each performance share grant is estimated on the date of grant using a Monte Carlo simulation 
to forecast relative TSR performance.  A correlation matrix of historic and projected stock prices was developed for both 
the  Company  and  our  predetermined  peer  group  of  mining  and  metals  companies.    The  fair  value  assumes  that 
performance goals will be achieved.

The expected term of the grant represents the time from the grant date to the end of the service period for each 
of the three plan-year agreements.  We estimate the volatility of our common shares and that of the peer group of mining 
and metals companies using daily price intervals for all companies.  The risk-free interest rate is the rate at the grant 
date on zero-coupon government bonds, with a term commensurate with the remaining life of the performance period.

The following assumptions were utilized to estimate the fair value for the 2015 performance share grants:

Stock Options

The fair value of each stock option grant is estimated on the date of grant using a Black-Scholes valuation 
model.  The expected term of the option grant is determined using the simplified method.  We estimate the volatility of 
our common shares using historical stock prices with consistent frequency over the most recent historical period equal 
to the option’s expected term.  The risk-free interest rate is the rate at the grant date on zero-coupon government bonds, 
with a term commensurate with the expected term.

At December 31, 2015 and 2014, we had $218.7 million and $219.1 million, respectively, of gross deferred tax 

assets related to U.S. alternative minimum tax credits that can be carried forward indefinitely.

We had gross domestic (including states) and foreign net operating loss carryforwards, inclusive of discontinued 
operations, of $3.9 billion, and $11.1 billion, respectively, at December 31, 2015.  We had gross domestic and foreign 
net operating loss carryforwards at December 31, 2014 of $1.9 billion and $4.5 billion, respectively.  The U.S. Federal 

138

 
 
 
 
Table of Contents

net operating losses will begin to expire in 2035 and state net operating losses will begin to expire in 2019.  The foreign 
net operating losses will begin to expire in 2022.  We had foreign tax credit carryforwards of $5.8 million at December 31, 
2015 and $5.8 million at December 31, 2014.  The foreign tax credit carryforwards will begin to expire in 2020.  Additionally, 
there is a net operating loss carryforward, inclusive of discontinued operations, of $1.6 billion for Alternative Minimum 
Tax.  No benefit has been recorded in the financials for this attribute as ASC 740, Income Taxes, does not allow for the 
recording of deferred taxes under alternative taxing systems.

We  recorded  a  $2.2  billion  net  increase  in  the  valuation  allowance  of  certain  deferred  tax  assets  where 
management believes that realization of the related deferred tax assets is not more likely than not.  Of this amount, a 
$165.8 million increase was recorded through continuing operations and relates to domestic deferred tax assets recorded 
in prior years for which future utilization is currently uncertain.  A $111.5 million decrease, also recorded through continuing 
operations, relates to the reversal of deferred tax assets due to current year operating activities.  The remainder of the 
$2.2 billion increase relates primarily to foreign deferred tax assets that were generated through discontinued operations 
in which it is more likely than not that the assets will not be realized.

At December 31, 2015 and 2014, we had no cumulative undistributed earnings of foreign subsidiaries included 
in consolidated retained earnings.  Accordingly, no provision has been made for U.S. deferred taxes related to future 
repatriation of earnings.

At December 31, 2015 and 2014, we had $156.2 million and $72.6 million, respectively, of unrecognized tax 
benefits recorded.  Of this amount, $21.5 million and $23.2 million were recorded in Other liabilities and $134.7 million 
and $49.4 million were recorded as Other non-current assets in the Statements of Consolidated Financial Position for 
both years.  If the $156.2 million were recognized, only $21.5 million would impact the effective tax rate.  We do not 
expect  that  the  amount  of  unrecognized  tax  benefits  will  change  significantly  within  the  next  twelve  months.    At 
December 31, 2015 and 2014, we had $2.1 million and $1.6 million, respectively, of accrued interest and penalties related 
to the unrecognized tax benefits recorded in Other liabilities in the Statements of Consolidated Financial Position.

On July 18, 2013, the FASB issued Accounting Standards Update No. 2013-11. Presentation of an Unrecognized 
Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (ASU 
2013-11).  ASU 2013-11 requires the netting of unrecognized tax benefits against a deferred tax asset for a loss or other 
carryforward that would apply in settlement of the uncertain tax positions except where the deferred tax asset or other 
carryforward are not available for use.  The adoption of the pronouncement does not have an impact in the presentation 
of our financial statement.

Tax years that remain subject to examination are years 2010 and forward for the U.S. and 2011 and forward for 

Australia.

NOTE 10 - LEASE OBLIGATIONS 

We lease certain mining, production and other equipment under operating and capital leases.  The leases are 
for varying lengths, generally at market interest rates and contain purchase and/or renewal options at the end of the 
terms.  Our operating lease expense was $12.0 million, $17.8 million and $23.6 million for the years ended December 31, 
2015, 2014 and 2013, respectively.  Capital lease assets were $32.5 million and $72.7 million at December 31, 2015 
and 2014, respectively.  In 2014 we had impairment charges of $64.0 million on our capital lease assets at our Asia 
Pacific Iron Ore operations.  Corresponding accumulated amortization of capital leases included in respective allowances 
for depreciation were $8.7 million and $14.9 million at December 31, 2015 and 2014, respectively.

Environmental

Our mining and exploration activities are subject to various laws and regulations governing the protection of the 
environment.  We conduct our operations to protect the public health and environment and believe our operations are 
in compliance with applicable laws and regulations in all material respects.  Our environmental liabilities of $3.6 million 
and $5.5 million at December 31, 2015 and 2014, respectively, including obligations for known environmental remediation 
exposures at various active and closed mining operations and other sites, have been recognized based on the estimated 
cost of investigation and remediation at each site.  If the cost only can be estimated as a range of possible amounts with 
no specific amount being more likely, the minimum of the range is accrued.  Future expenditures are not discounted 
unless the amount and timing of the cash disbursements readily are known.  Potential insurance recoveries have not 
been reflected.  Additional environmental obligations could be incurred, the extent of which cannot be assessed.

The Rio Tinto Mine Site

The Rio Tinto Mine Site is a historic underground copper mine located near Mountain City, Nevada, where tailings 
were placed in Mill Creek; a tributary to the Owyhee River. Site investigation and remediation work is being conducted 
in accordance with a Consent Order dated September 14, 2001 between the Nevada DEP and the RTWG composed 
of the Company, Atlantic Richfield Company, Teck Cominco American Incorporated and E. I. duPont de Nemours and 
Company. The Consent Order provides for technical review by the Rio Tinto Trustees. In recognition of the potential for 
an NRD claim, the parties actively pursued a global settlement that included the EPA and encompass both the remedial 
action and the NRD issues.

The Nevada DEP published a Record of Decision for the Rio Tinto Mine, which was signed on February 14, 
2012 by the Nevada DEP and the EPA. On September 27, 2012, the agencies subsequently issued a proposed Consent 
Decree, which was lodged with the U.S. District Court for the District of Nevada and subsequently finalized on May 20, 
2013.  Under the terms of the Consent Decree, the RTWG has agreed to pay over $29.0 million in cleanup costs and 
natural resource damages to the site and surrounding area. The Company's share of the total settlement cost, which 
includes remedial action, insurance and other oversight costs was $12.2 million.  As of December 31, 2015, we have no 
remaining required payments related to the Consent Decree compared to as of December 31, 2014, when we had $2.5 
million in the Statements of Consolidated Financial Position related to this issue. 

Mine Closure

Our mine closure obligations of $230.4 million and $165.3 million at December 31, 2015 and 2014, respectively, 
include our five consolidated U.S. operating iron ore mines, our Asia Pacific operating iron ore mine and a closed operation 
formerly operating as LTVSMC.

Management periodically performs an assessment of the obligation to determine the adequacy of the liability in 

141

 
 
 
 
 
 
 
 
Table of Contents

relation to the closure activities still required at the LTVSMC site.  The LTVSMC closure liability was $24.1 million and 
$22.9 million at December 31, 2015 and 2014, respectively.  MPCA is presently working on an NPDES permit reissuance 
for this facility that could modify the closure liability, but the scale of that change will not be understood until the permit 
has been drafted and issued.

The accrued closure obligation for our active mining operations provides for contractual and legal obligations 
associated  with  the  eventual  closure  of  the  mining  operations.    We  performed  a  detailed  assessment  of  our  asset 
retirement obligations related to our active mining locations most recently in 2014 in accordance with our accounting 
policy, which requires us to perform an in-depth evaluation of the liability every three years in addition to routine annual 
assessments. 

For the assessments performed, we determined the obligations based on detailed estimates adjusted for factors 
that a market participant would consider (i.e., inflation, overhead and profit) and then discounted the obligation using the 
current credit-adjusted risk-free interest rate based on the corresponding life of mine.  The estimate also incorporates 
incremental increases in the closure cost estimates and changes in estimates of mine lives.  The closure date for each 
location was determined based on the exhaustion date of the remaining iron ore reserves.  The accretion of the liability 
and amortization of the related asset is recognized over the estimated mine lives for each location.  

The following represents a roll forward of our asset retirement obligation liability related to our active mining 

locations for the years ended December 31, 2015 and 2014:

The revisions in estimated cash flows recorded during the year ended December 31, 2015 relate primarily to 
revisions in the timing of the estimated cash flows and the technology associated with required storm water management 
systems expected to be implemented subsequent to the indefinite idling of one of our U.S. Iron Ore mines.

For the year ended December 31, 2014, the revisions in estimated cash flows recorded during the year  primarily 
included a downward revision of estimated asset retirement costs for one of our U.S. Iron Ore mines associated with 
required storm water management systems.  The mine life was extended during 2014, effectively converting certain 
asset retirement costs to capital costs over the remaining life-of-mine.

NOTE 12 - GOODWILL AND OTHER INTANGIBLE ASSETS AND LIABILITIES 

Goodwill

Goodwill represents the excess purchase price paid over the fair value of the net assets of acquired companies 
and is not subject to amortization.  We assign goodwill arising from acquired companies to the reporting units that are 
expected to benefit from the synergies of the acquisition.  Our reporting units are either at the operating segment level 
or a component one level below our operating segments that constitutes a business for which management generally 
reviews  production  and  financial  results  of  that  component.    Decisions  often  are  made  as  to  capital  expenditures, 
investments and production plans at the component level as part of the ongoing management of the related operating 
segment.  We have determined that our Asia Pacific Iron Ore operating segment constitutes a separate reporting unit 
and that Northshore within our U.S. Iron Ore operating segment constitutes a reporting unit.  Goodwill is allocated among 
and evaluated for impairment at the reporting unit level in the fourth quarter of each year or as circumstances occur that 
potentially indicate that the carrying amount of these assets may exceed their fair value.

During the third quarter of 2014, a goodwill impairment charge of $73.5 million was recorded for our Asia Pacific 
Iron Ore reporting segment.  The impairment charge was a result of downward long-term pricing estimates as determined 
through management's long-range planning process. 

Refer to NOTE 6 - FAIR VALUE OF FINANCIAL INSTRUMENTS for further information.

The below-market sales contract is classified as a liability and recognized over the term of the underlying contract, 
which has a remaining life of approximately one year and expires December 31, 2016.  For the years ended December 31, 
2015, 2014 and 2013, we recognized $23.1 million, $23.1 million and $26.9 million, respectively, in Product revenues 
related to below-market sales contracts.  We estimate that $23.1 million will be recognized in Product revenues for the 
succeeding fiscal year.

Australian Foreign Exchange Contracts

We are subject to changes in foreign currency exchange rates as a result of our operations in Australia.  With 
respect to Australia, foreign exchange risk arises from our exposure to fluctuations in foreign currency exchange rates 
because the functional currency of our Asia Pacific operations is the Australian dollar.  Our Asia Pacific operations receive 
funds in U.S. currency for their iron ore sales. 

We were using foreign currency exchange contracts to hedge our foreign currency exposure for a portion of our 
U.S. dollar sales receipts in our Australian functional currency entities.  For our Australian operations, U.S. dollars were 
converted to Australian dollars at the currency exchange rate in effect during the period the transaction occurred.  The 
primary objective for the use of these instruments was to reduce exposure to changes in currency exchange rates and 
to protect against undue adverse movement in these exchange rates.  These instruments qualify for hedge accounting 
treatment and are tested for effectiveness at inception and at least once each reporting period.  If and when any of our 
hedge contracts are determined not to be highly effective as hedges, the underlying hedged transaction is no longer 
likely to occur, or the derivative is terminated, hedge accounting is discontinued.  As discussed in NOTE 1 - BASIS OF 
PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES, we suspended entering into new foreign exchange rate 
contracts and we have waived compliance with our current derivative financial instruments and hedging activities policy 
through December 31, 2016. 

144

 
 
 
 
 
Table of Contents

As of December 31, 2015, we had no outstanding Australian foreign currency exchange contracts.  This compares 
with  outstanding  Australian  foreign  currency  exchange  contracts  with  a  notional  amount  of  $220.0  million  as  of 
December 31, 2014. 

Changes  in  fair  value  of  highly  effective  hedges  are  recorded  as  a  component  of  Accumulated  other 
comprehensive loss in the Statements of Consolidated Financial Position.  Any ineffectiveness is recognized immediately 
in income.  As of December 31, 2015 and 2014, there was no material ineffectiveness recorded for foreign exchange 
contracts that were classified as cash flow hedges.  However, certain Australian hedge contracts were de-designated 
during the first quarter of 2015 and no longer qualified for hedge accounting treatment.  All of these de-designated hedges 
were settled and were no longer outstanding by March 31, 2015.  The de-designated hedges are discussed within the 
Derivatives Not Designated as Hedging Instruments section of this footnote.  Amounts recorded as a component of 
Accumulated other comprehensive loss are reclassified into earnings in the same period the forecasted transactions 
affect earnings. As of December 31, 2015, no amounts remain in Accumulated other comprehensive loss related to the 
designated Australian hedge contracts as the last forecasted transaction occured in October 2015.

Interest Rate Risk Management

Interest rate risk is managed using a portfolio of variable-rate and fixed-rate debt composed of short-term and 
long-term instruments, such as U.S. treasury lock agreements and variable-to-fixed interest rate swaps.  From time to 
time, these instruments, which are derivative instruments, are entered into to facilitate the maintenance of the desired 
ratio of variable-rate to fixed-rate debt.  

In the second quarter of 2012, we entered into U.S. treasury lock agreements with a notional value of $200.0 
million to hedge the exposure to the possible rise in the interest rate prior to the issuance of the five-year senior notes 
due 2018 discussed in NOTE 5 - DEBT AND CREDIT FACILITIES.  These derivative instruments were designated and 
qualified as cash flow hedges.  The U.S. treasury locks were settled in the fourth quarter of 2012 upon the issuance of 
$500.0 million principal amount of the senior notes due 2018 for a cumulative after-tax loss of $1.3 million, which was 
recorded in Accumulated other comprehensive loss and is being amortized to Other non-operating income (expense) 
over the life of the senior notes due 2018.  Approximately $0.1 million net of tax was recognized in earnings in both 2014 
and 2015 and approximately $0.1 million net of tax is expected to be recognized in earnings in 2016.

The following summarizes the effect of our derivatives designated as cash flow hedging instruments, net of tax 
in  Accumulated  other  comprehensive  loss  in  the  Statements  of  Consolidated  Operations  for  the  years  ended 
December 31, 2015, 2014 and 2013:

Derivatives Not Designated as Hedging Instruments

Foreign Exchange Contracts

During the first quarter of 2015, in connection with our refinancing initiatives, we discontinued hedge accounting 
and early-settled certain of our Australian foreign currency exchange contracts associated with Asia Pacific Iron Ore 
operations.  Subsequent to de-designation, no further foreign currency exchange rate contracts were entered into for 
the Asia Pacific Iron Ore operations.  The amounts that were previously recorded as a component of Accumulated other 
comprehensive loss prior to de-designation and remaining in Accumulated other comprehensive loss as of de-designation 
were reclassified to earnings and a corresponding realized loss was recognized when the forecasted cash flow occurred.  
For the year ended December 31, 2015, we reclassified losses of $12.6 million from Accumulated other comprehensive 
loss and recorded the amounts as Product revenues in the Statements of Consolidated Operations upon the occurrence 
of the forecasted cash flows associated with each de-designated and early-settled contract.  For the year ended December 
31, 2015, prior to the de-designation  of the Asia Pacific Iron Ore hedges  at the end of  the first quarter of 2015, we 
reclassified losses of $6.3 million from Accumulated other comprehensive loss related to contracts that matured during 
the year, and recorded the amounts as Product revenues in the Statements of Consolidated Operations.  As of December 
31, 2015, no gains or losses remain in Accumulated other comprehensive loss related to the effective cash flow hedge 
contracts prior to de-designation and early-settlement.

During the fourth quarter of 2014, we discontinued hedge accounting for Canadian foreign currency exchange 
contracts for all outstanding contracts associated with Bloom Lake operations as projected future cash flows were no 
longer considered probable or reasonably possible, but we continued to hold these instruments as economic hedges to 
manage currency risk. Our parent company held the Canadian foreign currency exchange contracts and the contracts 
were unaffected by Bloom Lake General Partner Limited and certain of its affiliates filing under the CCAA on January 
27, 2015.  Subsequent to de-designation, no further foreign currency exchange contracts were entered into for the Bloom 
Lake operations.  As of  December 31, 2015 no de-designated foreign exchange rate contracts remained outstanding. 
All outstanding Canadian de-designated foreign exchange rate contracts settled by the end of September 2015. As of 
December 31, 2014,the de-designated outstanding foreign exchange rate contracts had a notional amount of $183.0 
million in the form of forward contracts.

The amounts that were previously recorded as a component of Accumulated other comprehensive loss prior to 
de-designation and remaining in Accumulated other comprehensive loss as of December 31, 2014 were reclassified to 
earnings upon the de-designation of the hedges as the hedges would not be effective prospectively due to the projected 
future cash flows associated with the hedges no longer being considered probable or reasonably possible.  We reclassified 
losses of $7.3 million from Accumulated other comprehensive loss related to contracts that had not matured during the 
year, and recorded the amounts as Cost of goods sold and operating expenses on the Statements of Consolidated 
Operations.  A corresponding realized gain or loss was recognized in each period until settlement of the related economic 
hedge during 2015.  For the year ended December 31, 2015, the change in fair value of these de-designated foreign 
currency exchange contracts resulted in net losses of $3.6 million.

We  previously  discontinued  hedge  accounting  for  Canadian  foreign  currency  exchange  contracts  for  all 
outstanding contracts associated with the Wabush operation and the Ferroalloys operating segment as projected future 
cash flows were no longer considered probable, but we continued to hold these instruments as economic hedges to 
manage currency risk. Subsequent to de-designation, no further foreign currency exchange contracts were entered into 
for the Wabush operation or the Ferroalloys operating segment.  As of December 31, 2015 and 2014, there were no 
outstanding de-designated foreign currency exchange rate contracts as all remaining de-designated foreign exchange 
contracts matured during the second quarter of 2014.

Prior to the maturation of the contracts and as a result of discontinued hedge accounting, the instruments were 
prospectively adjusted to fair value each reporting period through Cost of goods sold and operating expenses in the 
Statements of Consolidated Operations.  For the years ended December 31, 2014 and 2013, the change in fair value of 
our de-designated foreign currency exchange contracts resulted in net losses of $3.3 million and $0.6 million, respectively. 
The  amounts  that  were  previously  recorded  as  a  component  of  Accumulated  other  comprehensive  loss  prior  to  de-
designation were reclassified to earnings and a corresponding realized gain or loss was recognized when the forecasted 
cash flow occurred.  For the years ended December 31, 2014 and 2013, we reclassified losses of $0.5 million and $1.9 
million, respectively, from Accumulated other comprehensive loss related to contracts that matured during the year, and 
recorded the amounts as Cost of goods sold and operating expenses in the Statements of Consolidated Operations. All 
the remaining contracts matured during the second quarter of 2014 and as of the period ended June 30, 2014, no gains 
or losses remained in Accumulated other comprehensive loss related to the effective cash flow hedge contracts prior to 
de-designation.

Fair Value Hedges

Interest Rate Hedges

Our fixed-to-variable interest rate swap derivative instruments, with a notional amount of $250.0 million, were 
de-designated and settled during August 2014.  Prior to settlement, the derivatives were designated and qualified as fair 
value hedges.  The objective of the hedges was to offset changes in the fair value of our debt instruments associated 
with fluctuations in the benchmark LIBOR interest rate as part of our risk management strategy.

Prior to de-designation and settlement, when the interest rate swap derivative instruments were designated and 
qualified as fair-value hedges, the gain or loss on the hedge instrument as well as the offsetting loss or gain on the 
hedged item attributable to the hedged risk were recognized in net income.  We included the gain or loss on the derivative 
instrument and the offsetting loss or gain on the hedged item in Other non-operating income (expense).  The net gains 
recognized in Other non-operating income (expense) for the year ended December 31, 2014 were $0.3 million.

For the year ended December 31, 2013, the fixed-to-variable interest rate swap derivative instruments were 
designated and qualified as fair-value hedges.  The gain or loss on the hedge instrument as well as the offsetting loss 
or gain on the hedged item attributable to the hedged risk was recognized in net income.  We included the gain or loss 
on the derivative instrument and the offsetting loss or gain on the hedged item in Other non-operating income (expense). 
The net gain recognized in Other non-operating income (expense) for year ended December 31, 2013 was $0.1 million.

Customer Supply Agreements

Most of our U.S. Iron Ore long-term supply agreements are comprised of a base price with annual price adjustment 
factors.  The base price is the primary component of the purchase price for each contract.  The indexed price adjustment 
factors are integral to the iron ore supply contracts and vary based on the agreement, but typically include adjustments 
based upon changes in the Platts 62 percent Fe fines spot price and/or international pellet prices and changes in specified 
Producer Price Indices, including those for industrial commodities, energy and steel.  The pricing adjustments generally 
operate in the same manner, with each factor typically comprising a portion of the price adjustment, although the weighting 
of each factor varies based upon the specific terms of each agreement.  In most cases, these adjustment factors have 
not been finalized at the time our product is sold.  In these cases, we historically have estimated the adjustment factors 
at each reporting period based upon the best third-party information available.  The estimates are then adjusted to actual 
when the information has been finalized.  The price adjustment factors have been evaluated to determine if they contain 
embedded derivatives.  The price adjustment factors share the same economic characteristics and risks as the host 
contract and are integral to the host contract as inflation adjustments; accordingly, they have not been separately valued 
as derivative instruments.  Certain of our term supply agreements contain price collars, which typically limit the percentage 
increase or decrease in prices for our products during any given year.

A certain supply agreement with one U.S. Iron Ore customer provides for supplemental revenue or refunds to 
the customer based on the customer’s average annual steel pricing at the time the product is consumed in the customer’s 
blast furnace.  The supplemental pricing is characterized as a freestanding derivative and is required to be accounted 
for separately once the product is shipped.  The derivative instrument, which is finalized based on a future price, is 
adjusted to fair value as a revenue adjustment each reporting period until the pellets are consumed and the amounts 
are settled.  

We  recognized  $27.1  million,  $187.8  million  and  $149.2  million  as  Product  revenues  in  the  Statements  of 
Consolidated  Operations  for  the  years  ended  December 31,  2015,  2014  and  2013,  respectively,  related  to  the 
supplemental payments.  Other current assets, representing the fair value of the pricing factors, were $5.8 million and 
$63.2  million  in  the  December 31,  2015  and  December 31,  2014  Statements  of  Consolidated  Financial  Position, 
respectively.

Provisional Pricing Arrangements

Certain of our U.S. Iron Ore and Asia Pacific Iron Ore customer supply agreements specify provisional price 
calculations, where the pricing mechanisms generally are based on market pricing, with the final revenue rate to be 
based on market inputs at a specified period in time in the future, per the terms of the supply agreements.  U.S. Iron Ore 
sales  revenue  is  primarily  recognized  when  cash  is  received.   For  U.S.  Iron  Ore  sales,  the  difference  between  the 
provisionally agreed-upon price and the estimated final revenue rate is characterized as a freestanding derivative and 
must be accounted for separately once the provisional revenue has been recognized.  Asia Pacific Iron Ore sales revenue 
is recorded initially at the provisionally agreed-upon price with the pricing provision embedded in the receivable.  The 
pricing provision is an embedded derivative that must be bifurcated and accounted for separately from the receivable.  
Subsequently, the derivative instruments for both U.S. Iron Ore and Asia Pacific Iron Ore are adjusted to fair value through 

147

 
 
 
 
 
 
 
 
 
 
 
Table of Contents

Product revenues each reporting period based upon current market data and forward-looking estimates provided by 
management until the final revenue rate is determined.  At December 31, 2015 we recorded $2.0 million as Other current 
assets in the Statements of Consolidated Financial Position related to our estimate of the final revenue rate with any of 
our customers.  At December 31, 2014, we recorded no Other current assets in the Statements of Consolidated Financial 
Position  related  to  our  estimate  of  the  final  revenue  rate  with  any  of  our  customers.   At  December 31,  2015  and 
December 31, 2014, we recorded $3.4 million and $9.5 million, respectively, as Other current liabilities in the Statements 
of Consolidated Financial Position related to our estimate of final revenue rate with our U.S. Iron Ore and Asia Pacific 
Iron  Ore  customers.    These  amounts  represent  the  difference  between  the  provisional  price  agreed  upon  with  our 
customers based on the supply agreement terms and our estimate of the final revenue rate based on the price calculations 
established in the supply agreements.  As a result, we recognized a net $1.4 million decrease in Product revenues in 
the Statements of Consolidated Operations for the year ended December 31, 2015 related to these arrangements.  This 
compares with a net $9.5 million decrease and a net $7.5 million decrease in Product revenues for the comparable 
periods in 2014 and 2013.

Loss from Discontinued Operations, net of tax during the year end December 31, 2013 also includes an additional income 
tax benefit of $2.0 million resulting from the actual tax gain from the Sale of Sonoma as included in the 2012 tax return, which 
was filed during the year ended December 31, 2013.  During the fourth quarter of 2012, we sold our 45 percent economic 
interest in Sonoma.  The Sonoma operations previously were included in Other within our reportable segments.

North American Coal Operations

Background

  As  we  continue  to  execute  our  strategy  which  focuses  on  strengthening  our  U.S.  Iron  Ore  operations, 
management determined as of March 31, 2015 that our North American Coal operating segment met the criteria to be 
classified as held for sale under ASC 205, Presentation of Financial Statements.  The North American Coal segment 
continued to meet the criteria throughout 2015 until we sold our held for sale North American Coal operations during the 
fourth quarter of 2015.  As such, all current and historical North American Coal operating segment results are included 
in our financial statements and classified within discontinued operations. 

In  the  first  quarter  of  2015,  as  part  of  the  held  for  sale  classification  assigned  to  North American  Coal,  an 
impairment of $73.4 million was recorded.  The impairment charge was to reduce the assets to their estimated fair value 
which was determined based on potential sales scenarios.  No further impairment was recorded in 2015.

Consistent with our strategy to extract maximum value from our current assets, we sold all the remaining North 
American Coal operations during the fourth quarter of 2015. On December 22, 2015, we closed the sale of our remaining 
North American Coal business which included Pinnacle mine in West Virginia and Oak Grove mine in Alabama.  Pinnacle 
mine and Oak Grove mine were sold to Seneca and the deal structure was a sale of equity interests of our remaining 
coal business.  Additionally, Seneca may pay Cliffs an earn-out of up to $50 million contingent upon the terms of a revenue 
sharing agreement which extends through the year 2020.  However, we have not recorded a gain contingency in relation 
to  this  earn-out.    We  recorded  the  results  of  this  sale  in  our  fourth  quarter  earnings  within  Loss  from  Discontinued 
Operations, net of tax as the transaction closed on December 22, 2015. 

On December 31, 2014, we completed the sale of our CLCC assets in West Virginia to Coronado Coal II, LLC, 
an affiliate of Coronado Coal LLC, for $174.0 million in cash and the assumption of certain liabilities, of which $155.0 
million was collected as of December 31, 2014.  We recorded the results of this sale in our fourth quarter earnings within 
Loss from Discontinued Operations, net of tax as the transaction closed on December 31, 2014. 

Loss on Discontinued Operations 

Our planned sale of the Oak Grove and Pinnacle mine assets represented a strategic shift in our business.  For 
that reason, our previously reported North American Coal operating segment results for all periods, prior to the March 
31, 2015 held for sale determination, are classified as discontinued operations. On December 22, 2015, we completed 
the sale of the Oak Grove and Pinnacle mines, which marked our exit from the coal business.  Historic results also include 
our CLCC assets, which were sold during the fourth quarter of 2014.

In  the  first  quarter  of  2015,  as  part  of  the  held  for  sale  classification  assigned  to  North American  Coal,  an 
impairment charge of $73.4 million was recorded.  The impairment charge was to reduce the assets to their estimated 
fair value which was determined based on potential sales scenarios.  We determined the fair value and recoverability of 
our North American Coal operating segment by comparing the estimated fair value of the underlying assets and liabilities 
to the estimated sales price of the operating segment held for sale.  No further impairment was recorded in 2015.

As part of the CLCC asset sale during the fourth quarter of 2014, there was an amount placed in escrow to cover 
decreases in working capital, indemnity obligations and regulatory liabilities. The amount held in escrow was $14.9 million 
and $17.5 million  at December 31, 2015, and 2014, respectively and recorded within Short-term assets of discontinued 
operations and Long-term assets of discontinued operations, respectively, on the Statements of Consolidated Financial 
Position. 

Income Taxes 

We have recognized a tax benefit of $0.2 million and $302.2 million for the years ended December 31, 2015 and 
2014,  respectively,  in  Loss  from  Discontinued  Operations,  net  of  tax,  related  to  a  loss  on  our  North American  Coal 
investments.  The benefit for the year ended December 31, 2014 is primarily the result of the impairment of long-lived 
assets in the third quarter of 2014.  We recognized a tax expense of $6.2 million for the year ended December 31, 2013 
in Loss from Discontinued Operations, net of tax, related to the impact of the North American Coal losses on the AMT 
credit and associated valuation allowance.

Canadian Operations

Background

On November 30, 2013, we suspended indefinitely our Chromite Project in Northern Ontario.  The Chromite 
Project  remained  suspended  throughout  2014  and  until  final  sale  in  2015.  Our  Wabush  Scully  iron  ore  mine  in 
Newfoundland and Labrador was idled by the end of the first quarter of 2014 and subsequently began to commence 
permanent closure in the fourth quarter of 2014. During 2014, we also limited exploration spending on the Labrador 
Trough South property in Québec.  In November 2014, we announced that we were pursuing exit options for our Eastern 
Canadian Iron Ore operations.  In December 2014, iron ore production at the Bloom Lake mine was suspended and the 
Bloom Lake mine was placed in "care-and-maintenance" mode. Together, the suspension of exploration efforts, shutdown 
of the Wabush Scully mine and the cessation of operations at our Bloom Lake mine represent a complete curtailment of 
our Canadian operations.

On January 27, 2015, we announced the Bloom Filing under the CCAA with the Québec Court in Montreal.  At 
that time, the Bloom Lake Group was no longer generating revenues and was not able to meet its obligations as they 
came due.  The Bloom Filing addressed the Bloom Lake Group's immediate liquidity issues and permits the Bloom Lake 
Group  to  preserve  and  protect  its  assets  for  the  benefit  of  all  stakeholders  while  restructuring  and  sale  options  are 
explored.  As part of the CCAA process, the Court approved the appointment of a Monitor and certain other financial 
advisors. 

 Additionally, on May 20, 2015, we announced the Wabush Filing in the Court under the CCAA.  As a result of 
this action, the CCAA protections granted to the Bloom Lake Group were extended to include the Wabush Group to 
facilitate the reorganization of each of their businesses and operations.  The Wabush Group was no longer generating 
revenues and was not able to meet its obligations as they came due.  The inclusion of the Wabush Group in the existing 
Bloom Filing facilitates a more comprehensive restructuring and sale process of both the Bloom Lake Group and the 
Wabush Group which collectively include mine, port and rail assets and leads to a more effective and streamlined exit 
from Eastern Canada.  The Wabush Filing also mitigates various legacy related long-term liabilities associated with the 
Wabush Group.  As part of the Wabush Filing, the Court approved the appointment of a Monitor and certain other financial 
advisors.  The Monitor of the Wabush Group is also the Monitor of the Bloom Lake Group.

As a result of the Bloom Filing on January 27, 2015, we no longer have a controlling interest in the Bloom Lake 
Group.  For that reason, we deconsolidated the Bloom Lake Group and certain other wholly-owned subsidiaries effective 
January 27, 2015, which resulted in a pretax impairment loss on deconsolidation and other charges, totaling $818.7 
million that was recorded in the first quarter of 2015.  The pretax loss on deconsolidation includes the derecognition of 
the  carrying  amounts  of  the  Bloom  Lake  Group  and  certain  other  wholly-owned  subsidiaries  assets,  liabilities  and 
accumulated other comprehensive loss and the recording of our remaining interests at fair value. 

As a result of the Wabush Filing, we deconsolidated certain Wabush Group wholly-owned subsidiaries effective 
May 20, 2015.  The certain wholly-owned subsidiaries that were deconsolidated effective May 20, 2015 are Wabush 
Group entities that were not deconsolidated as part of the deconsolidation effective January 27, 2015 as discussed 
previously in this section.  This deconsolidation, effective May 20, 2015, resulted in a pretax gain on deconsolidation and 
other charges, totaling $134.7 million.  The pretax gain on deconsolidation includes the derecognition of the carrying 
amounts of these certain deconsolidated Wabush Group wholly-owned subsidiaries' assets, liabilities and accumulated 
other comprehensive loss and the adjustment of our remaining interests in the Canadian Entities to fair value.

Table of Contents

Subsequent to each of the deconsolidations discussed above, we utilized the cost method to account for our 
investment  in  the  Canadian  Entities,  which  has  been  reflected  as  zero  in  our  Statements  of  Consolidated  Financial 
Position as of December 31, 2015 based on the estimated fair value of the Canadian Entities' net assets.  Loans to and 
accounts receivable from the Canadian Entities are recorded at an estimated fair value of $72.9 million classified as 
Loans to and accounts receivables from the Canadian Entities  in the Statements of Consolidated Financial Position as 
of December 31, 2015.

Loss on Discontinued Operations 

Our Canadian exit represents a strategic shift in our business.  For this reason, our previously reported Eastern 
Canadian Iron Ore and Ferroalloys operating segment results for all periods prior to the respective deconsolidations, as 
well as costs to exit, are classified as discontinued operations.

As a result of the deconsolidation, we recorded accrued expenses for the estimated probable loss related to 
claims that may be asserted against us, primarily under guarantees of certain debt arrangements and leases for a loss 
on deconsolidation of $203.1 million, for the twelve months ended December 31, 2015.

Investments in the Canadian Entities

Cliffs continues to indirectly own a majority of the interest in the Canadian Entities but has deconsolidated those 
entities because Cliffs no longer has a controlling interest as a result of the Bloom Filing and the Wabush Filing.  At the 
respective dates of deconsolidation, January 27, 2015 or May 20, 2015 and subsequently at each reporting period, we 
adjusted our investment in the Canadian Entities to fair value with a corresponding charge to Loss from Discontinued 
Operations, net of tax.  As the estimated amount of the Canadian Entities' liabilities exceeded the estimated fair value 
of the assets available for distribution to its creditors, the fair value of Cliffs’ equity investment is approximately zero.

Table of Contents

Amounts Receivable from the Canadian Entities

Prior to the deconsolidations, various Cliffs wholly-owned entities made loans to the Canadian Entities for the 
purpose of funding its operations and had accounts receivable generated in the ordinary course of business.  The loans, 
corresponding interest and the accounts receivable were considered intercompany transactions and eliminated in our 
consolidated financial statements.  Additionally, we procured funding subsequent to the deconsolidation through a debtor-
in-possession credit facility (the "DIP financing").  Since the deconsolidations, the loans, associated interest and accounts 
receivable are considered related party transactions and have been recognized in our consolidated financial statements 
at their estimated fair value of $72.9 million classified as Other current assets in the Statements of Consolidated Financial 
Position at December 31, 2015.

Guarantees and Contingent Liabilities

 Certain liabilities, consisting primarily of equipment loans and environmental obligations of the Canadian Entities, 
were secured through corporate guarantees and standby letters of credit.  As of December 31, 2015, we have liabilities 
of $96.5 million and $35.9 million in our consolidated results, classified as Guarantees and Other liabilities, respectively, 
in the Statements of Consolidated Financial Position. 

Contingencies 

The recorded expenses include an accrual for the estimated probable loss related to claims that may be asserted 
against us, primarily under guarantees of certain debt arrangements and leases.  The beneficiaries of those guarantees 
may seek damages or other related relief as a result of our exit from Canada.  Our probable loss estimate is based on 
the  expectation  that  claims  will  be  asserted  against  us  and  negotiated  settlements  will  be  reached,  and  not  on  any 
determination  that  it  is  probable  we  would  be  found  liable  were  these  claims  to  be  litigated.    Our  estimates  involve 
significant judgment. Our estimates are based on currently available information, an assessment of the validity of certain 
claims and estimated payments by the Canadian Entities.  We are not able to reasonably estimate a range of possible 
losses in excess of the accrual because there are significant factual and legal issues to be resolved.  We believe that it 
is reasonably possible that future changes to our estimates of loss and the ultimate amount paid on these claims could 
be material to our results of operations in future periods.  Any such losses would be reported in discontinued operations.

We determined the fair value and recoverability of our Canadian investments by comparing the estimated fair 
value of the remaining underlying assets of the Canadian Entities to remaining estimated liabilities.  We recorded the 
guarantees and contingent liabilities at book value which best approximated fair value.

Outstanding  liabilities  include  accounts  payable  and  other  liabilities,  forward  commitments,  unsubordinated 
related party payables, lease liabilities and other potential claims.  Potential claims include an accrual for the estimated 
probable loss related to claims that may be asserted against the Bloom Lake Group and Wabush Group under certain 
contracts. Claimants may seek damages or other related relief as a result of the Canadian Entities' exit from Canada.  
Based on our estimates, the fair value of liabilities exceeds the fair value of assets.

Table of Contents

To assess the fair value and recoverability of the amounts receivable from the Canadian Entities, we estimated 
the fair value of the underlying net assets of the Canadian Entities available for distribution to their creditors in relation 
to the estimated creditor claims and the priority of those claims. 

Our estimates involve significant judgment and are based on currently available information, an assessment of 
the validity of certain claims and estimated payments made by the Canadian Entities.  Our ultimate recovery is subject 
to the final liquidation value of the Canadian Entities.  Further, the final liquidation value and ultimate recovery of the 
creditors of the Canadian Entities, including Cliffs Natural Resources and various subsidiaries, may impact our estimates 
of contingent liability exposure described previously. 

Pre-Petition Financing

Prior to the Wabush Filing on May 20, 2015, a secured credit facility (the "Pre-Petition financing") was put into 
place to provide support to the Wabush Group for ongoing business activities until the DIP financing was in place. As of 
December 31, 2015, there was a total of $7.2 million drawn and outstanding under the Pre-Petition financing funded by 
Wabush Iron Co. Limited’s parent company, Cliffs Mining Company.  The Pre-Petition financing amount of $7.2 million 
is included within the Loans to and accounts receivables from the Canadian Entities of $72.9 million.  The Pre-Petition 
financing is secured by certain equipment of the Wabush Group.

DIP Financing

In connection with the Wabush Filing on May 20, 2015, the Court approved the DIP financing to the Wabush 
Group, which provides for borrowings under the facility up to $10.0 million.  As of December 31, 2015, there was $6.8 
million drawn  and outstanding  under  the DIP financing  funded  by  Wabush Iron Co.  Limited’s  parent company,  Cliffs 
Mining Company.  At December 31, 2015, the DIP financing is included within Loans to and accounts receivables from 
the Canadian Entities on the Statements of Consolidated Financial Position.  The DIP financing is secured by a court 
order over the assets of the Wabush Group.

Income Taxes 

We recognized a tax benefit of $5.8 million and $913.7 million for the years ended December 31, 2015 and 2014, 
respectively, in Loss from Discontinued Operations, net of tax. The benefit for the year ended December 31, 2014 was 
the result of the impairment of long-lived assets in the third quarter of 2014 offset by the placement of a valuation allowance 
against the Canadian operations net deferred tax assets.  Canadian deferred tax assets relating to both historical and 
current year net operating losses were included in our equity investment in the Canadian Subsidiaries that has been 
reduced to zero.  We recognized a tax benefit of $188.7 million for the year ended December 31, 2013 in Loss from 
Discontinued Operations, net of tax related to losses in our Canadian operations.

NOTE 15 - CAPITAL STOCK 

Preferred Shares

On February 21, 2013, we issued 29.25 million depositary shares, representing an aggregate of 731,250 preferred 
shares, comprised of the 27.0 million depositary share offering and the exercise of an underwriters' over-allotment option 
to purchase an additional 2.25 million depositary shares.  Each depositary share represents a 1/40th interest in a share 
of our 7.00 percent Series A Mandatory Convertible Preferred Stock, Class A, without par value ("Series A preferred 
share") at a price of $25 per depositary share for total net proceeds of approximately $709.4 million, after underwriter 
fees and discounts.  Each Series A preferred share has an initial liquidation preference of $1,000 per share (equivalent 
to a $25 liquidation preference per depositary share).  Pursuant to the terms of the Series A preferred shares, unless 
earlier converted at the option of the holder, each Series A preferred share automatically converted into common shares 
on February 1, 2016.  When and if declared by our Board of Directors, we paid cumulative dividends on each Series A 
preferred  share  at  an  annual  rate  of  7.00  percent  on  the  liquidation  preference.    We  declared  dividends  in  cash  on 
February 1, May 1, August 1 and November 1 of each year, commencing on May 1, 2013.  Upon determination by our 
Board of Directors, the final quarterly dividend was not paid in cash, but instead, pursuant to the terms of the Series A 
preferred shares, the conversion rate was increased such that holders of the Series A preferred shares received additional 
common shares in lieu of the accrued dividend at the time of the mandatory conversion on February 1, 2016.  The number 
of common shares in the aggregate that were issued in lieu of the final dividend was 1.3 million based on an effective 
conversion rate of 0.9052 common shares, rather than 0.8621 common shares, per depositary share, each representing 
a 1/40th interest in a Series A preferred share.

Prior to the mandatory conversion, holders of the depositary shares were entitled to a proportional fractional 
interest in the rights and preferences of the Series A preferred shares, including conversion, dividend, liquidation and 
voting rights, subject to the provisions of the deposit agreement.  The Series A preferred shares were convertible, at the 
option of the holder, at the minimum conversion rate of 28.1480 of our common shares (equivalent to 0.7037 of our 
common shares per depositary share) at any time prior to February 1, 2016 or other than during a fundamental change 
conversion period, subject to anti-dilution adjustments.  If not converted prior to that time, each Series A preferred share 
converted automatically on February 1, 2016 into between 28.1480 and 34.4840 common shares, par value $0.125 per 
share, subject to anti-dilution adjustments.  The number of common shares issued on conversion was determined based 
on the average VWAP per share of our common shares during the 20 trading day period beginning on, and including, 
the 23rd scheduled trading day prior to February 1, 2016, subject to customary anti-dilution adjustments.  Upon conversion 
on February 1, 2016, an aggregate of 26.5 million common shares were issued, representing 25.2 million common shares 
issuable upon conversion and 1.3 million that were issued in lieu of a final cash dividend. 

Common Share Public Offering 

On February 21, 2013, we issued 10.35 million common shares, comprised of the 9.0 million common share 
offering and the exercise of an underwriters' option to purchase an additional 1.35 million common shares.  We received 
net proceeds of approximately $285.3 million at a closing price of $29.00 per common share.

On March 27, 2015, July 1, 2015 and September 10, 2015, our Board of Directors declared the quarterly cash 
dividend of $17.50 per Preferred Share, which is equivalent to approximately $0.44 per depositary share.  The cash 
dividend was paid on May 1, 2015, August 3, 2015 and November 2, 2015 to our shareholders of record as of the close 
of business on April 15, 2015, July 15, 2015 and October 15, 2015, respectively.

On  February  11,  2014,  May  13,  2014,  September  8,  2014  and  November  19,  2014,  our  Board  of  Directors 
declared the quarterly cash dividend of $17.50 per Preferred Share, which is equivalent to approximately $0.44 per 
depositary share.  The cash dividend was paid on May 1, 2014, August 1, 2014, November 3, 2014 and February 2, 
2015, to our Preferred Shareholders of record as of the close of business on April 15, 2014, July 15, 2014, October 15, 
2014 and January 15, 2015, respectively.

On February 11, 2013, our Board of Directors approved a reduction to our quarterly cash dividend rate by 76 
percent to $0.15 per share.  Our Board of Directors took this step in order to provide us with additional free cash flow as 
well as to preserve our investment-grade credit ratings.  The cash dividend of $0.15 per share was paid on March 3, 
2014, June 3, 2014, September 2, 2014 and December 1, 2014 to our common shareholders of record as of close of 
business on February 21, 2014, May 23, 2014, August 15, 2014 and November 15, 2014.

On January 26, 2015, we announced that our Board of Directors had decided to eliminate the quarterly dividend 
of $0.15 per share on our common shares.  The decision was applicable to the first quarter of 2015 and all subsequent 
quarters.

NOTE 18 - RELATED PARTIES 

Three of our five U.S. iron ore mines are owned with various joint venture partners that are integrated steel 
producers or their subsidiaries.  We are the manager of each of the mines we co-own and rely on our joint venture 
partners to make their required capital contributions and to pay for their share of the iron ore pellets that we produce.  
One or more of the joint venture partners are also our customers.  The following is a summary of the mine ownership of 
these iron ore mines at December 31, 2015:

ArcelorMittal has a unilateral right to put its interest in the Empire mine to us, but has not exercised this right to 
date.  Furthermore, as part of a 2014 extension agreement between us and ArcelorMittal, which amended certain terms 
of the Empire partnership agreement, certain minimum distributions of the partners’ equity amounts are required to be 
made on a quarterly basis beginning in the first quarter of 2015 and will continue through January 2017.  During the year 
ended December 31, 2015, we recorded distributions of $51.7 million to ArcelorMittal under this agreement of which 
$40.6 million was paid as of December 31, 2015.

NOTE 20 - COMMITMENTS AND CONTINGENCIES 

Contingencies

Litigation

We are currently a party to various claims and legal proceedings incidental to our operations.  If management 
believes that a loss arising from these matters is probable and can reasonably be estimated, we record the amount of 
the loss, or the minimum estimated liability when the loss is estimated using a range, and no point within the range is 
more probable than another.  As additional information becomes available, any potential liability related to these matters 
is assessed and the estimates are revised, if necessary.  Based on currently available information, management believes 
that the ultimate outcome of these matters, individually and in the aggregate, will not have a material effect on our financial 
position, results of operations or cash flows.  However, litigation is subject to inherent uncertainties, and unfavorable 
rulings  could  occur.   An  unfavorable  ruling  could  include  monetary  damages,  additional  funding  requirements  or  an 
injunction.  If an unfavorable ruling were to occur, there exists the possibility of a material impact on the financial position 
and results of operations of the period in which the ruling occurs, or future periods.  However, we do not believe that any 
pending  litigation,  not  covered  by  insurance,  will  result  in  a  material  liability  in  relation  to  our  consolidated  financial 
statements.  Currently, we have an insurance coverage receivable to cover settlement of the following putative class 
action and derivative shareholder lawsuits:

In May 2014, alleged purchasers of our common shares filed suit in the U.S. District Court for the Northern District 
of Ohio against us and certain former officers and directors of the Company.  The action is captioned Department of the 
Treasury of the State of New Jersey and Its Division of Investment v. Cliffs Natural Resources Inc., et al., No. 1:14-
CV-1031.  As amended, the action asserts violations of the federal securities laws based on alleged false or misleading 
statements or omissions during the period of March 14, 2012 to March 26, 2013, regarding operations at our Bloom Lake 
mine in Québec, Canada, and the impact of those operations on our finances and outlook, including sustainability of the 
dividend, and that the alleged misstatements caused our common shares to trade at artificially inflated prices.  The parties 
have  successfully  mediated  this  dispute  and  reached  a  settlement  in  principle,  subject  to  definitive  documentation, 
shareholder notice and court approval.  The lawsuit had been referred to our insurance carriers, who will be required to 
pay the entirety of the $84 million settlement amount, if approved by the court.  The court is expected to schedule a 
settlement approval hearing. 

In June 2014, an alleged purchaser of the depositary shares issued by Cliffs in a public offering in February 2013 
filed a putative class action, which is captioned Rosenberg v. Cliffs Natural Resources Inc., et al., and after a round of 
removal and remand motions, is now pending in the Cuyahoga County, Ohio, Court of Common Pleas, No. CV-14-828140. 
As amended, the suit asserts claims against us, certain current and former officers and directors of the Company, and 
several underwriters of the offering, alleging disclosure violations in the offering documents regarding operations at our 
Bloom Lake mine, the impact of those operations on our finances and outlook, and about the progress of our former 
exploratory chromite project in Ontario, Canada.  The parties successfully mediated this dispute and reached a settlement 
agreement in principle, subject to definitive documentation, notice to class members and court approval.  The settlement 
provides for a payment to the proposed class of $10 million, which has been deposited into escrow by the insurance 
carriers.  A court hearing, during which the parties will seek court approval of the proposed class action settlement, is 
scheduled for April 14, 2016.

In June and July 2014, alleged shareholders of Cliffs filed three derivative actions in the Cuyahoga County, Ohio, 
Court of Common Pleas asserting claims against certain current and former officers and directors of the Company.  These 
actions, captioned Black v. Carrabba, et al., No. CV-14-827803, Asmussen v. Carrabba, et al., No. CV-14-829259, and 
Williams, et al. v. Carrabba, et al., No. CV-14-829499, allege that the individually named defendants violated their fiduciary 
duties to the Company by, among other things, disseminating false and misleading information regarding operations at 
our Bloom Lake mine in Québec, Canada, and the impact of those operations on our finances and outlook, including 
sustainability of the dividend, failing to maintain internal controls, and failing to appropriately oversee and manage the 
Company.   The  complaints  assert  additional  claims  for  unjust  enrichment,  abuse  of  control,  gross  mismanagement, 
overpayment upon departure of certain executives, and waste of corporate assets. The parties have reached a settlement 
in principle to settle all three cases, subject to definitive documentation, shareholder notice and court approval.  Under 
the pending settlement, the Company will agree to enact or continue various corporate-governance related measures 
and to pay plaintiffs' attorneys' fees and expenses.  The lawsuit had been referred to our insurance carriers who will pay 
$775,000 for attorneys' fees and expenses to plaintiffs' lawyers.  The settlement of these actions will have no impact on 
our financial position.  Following the announcement of the settlement in principle of these three shareholder derivative 
cases, an additional derivative shareholder action, captioned Mansour v. Carrabba, et al., No. 16-CV-00390, was filed 
in the U.S. District Court for the Northern District of Ohio against the same defendants and alleging substantially identical 
claims.  This additional lawsuit has been referred to our insurance carriers.

Environmental Matters

We had environmental liabilities of $3.6 million and $5.5 million at December 31, 2015 and 2014, respectively, 
including obligations for known environmental remediation exposures at active and closed mining operations and other 
sites.  These amounts have been recognized based on the estimated cost of investigation and remediation at each site, 
and include site studies, design and implementation of remediation plans, legal and consulting fees, and post-remediation 
monitoring and related activities.  If the cost can only be estimated as a range of possible amounts with no specific 
amount being more likely, the minimum of the range is accrued.  Future expenditures are not discounted unless the 
amount and timing of the cash disbursements are readily known.  Potential insurance recoveries have not been reflected.  
Additional environmental obligations could be incurred, the extent of which cannot be assessed.  The amount of our 
ultimate liability with respect to these matters may be affected by several uncertainties, primarily the ultimate cost of 
required remediation and the extent to which other responsible parties contribute.  Refer to NOTE 11 - ENVIRONMENTAL 
AND MINE CLOSURE OBLIGATIONS for further information.

Tax Matters

The calculation of our tax liabilities involves dealing with uncertainties in the application of complex tax regulations.  
We  recognize  liabilities  for  anticipated  tax  audit  issues  based  on  our  estimate  of  whether,  and  the  extent  to  which, 
additional taxes will be due.  If we ultimately determine that payment of these amounts is unnecessary, we reverse the 
liability and recognize a tax benefit during the period in which we determine that the liability is no longer necessary.  We 
also recognize tax benefits to the extent that it is more likely than not that our positions will be sustained when challenged 
by the taxing authorities.  To the extent we prevail in matters for which liabilities have been established, or are required 
to  pay  amounts  in  excess  of  our  liabilities,  our  effective  tax  rate  in  a  given  period  could  be  materially  affected.   An 
unfavorable tax settlement would require use of our cash and result in an increase in our effective tax rate in the year of 
resolution.  A favorable tax settlement would be recognized as a reduction in our effective tax rate in the year of resolution.  
Refer to NOTE 9 - INCOME TAXES for further information.

NOTE 21 - SUBSEQUENT EVENTS 

Preferred Shares

On January 4, 2016, we announced that under the terms of our 7.00 percent Series A Mandatory Convertible 
Preferred Stock, Class A ("Series A preferred shares"), the final quarterly dividend would not be paid in cash.  Instead, 
pursuant to the terms of the Series A preferred shares, the conversion rate was increased such that holders of the Series 
A preferred shares received additional common shares in lieu of the accrued dividend at the time of the mandatory 
conversion  of  the  Series A  preferred  shares  on  February  1,  2016.    In  accordance  with  applicable  law,  our  Board  of 
Directors determined not to declare a dividend payable in cash.  The number of our common shares in the aggregate 
issued in lieu of the dividend was approximately 1.3 million.  This resulted in an effective conversion rate of 0.9052 
common shares, rather than 0.8621 common shares, per depositary share, each representing 1/40th of a share of Series 
A preferred shares.  Upon conversion on February 1, 2016, an aggregate of 26.5 million common shares were issued, 
representing 25.2 million common shares issuable upon conversion and 1.3 million that were issued in lieu of a final 
cash dividend.

Exchange Offers

On January 27, 2016, we announced the Exchange Offers for up to $710 million aggregate principal amount of 
our New 1.5 Lien Notes for certain Existing Notes of Cliffs, upon the terms and subject to the conditions set forth in our

their Existing Notes on February 9, 2016, the Early Tender Date, in order to be eligible to receive the applicable total 
exchange consideration, which includes an early tender premium.  On February 10, 2016, we announced that as of the 
Early Tender Date, a total of approximately $465.3 million principal amount of Existing Notes had been tendered in the 
Exchange Offers.  We also announced that the Early Tender Date has been extended to February 26, 2016, and that

The diluted earnings per share calculation for the first, second and third quarters of 2014 exclude depositary 
shares  that  were  anti-dilutive  totaling  25.2  million.   Additionally,  the  third  quarter  of  2014  diluted  earnings  per  share 
calculation also excludes 0.5 million of equity plan awards.  There was no anti-dilution for the fourth quarter of 2014.

Fourth Quarter Results

Consistent with our strategy to extract maximum value from our current assets, we sold all the remaining North 
American Coal operations during the fourth quarter of 2015. On December 22, 2015, we closed the sale of our remaining 
North American Coal business, which included Pinnacle mine in West Virginia and Oak Grove mine in Alabama.  Pinnacle 
mine and Oak Grove mine were sold to Seneca and the deal structure was a sale of equity interests of our remaining 
coal business.  Additionally, Seneca may pay Cliffs an earn-out of up to $50 million contingent upon the terms of a revenue 
sharing agreement which extends through the year 2020.  We recorded the results of this sale in our fourth quarter 
earnings within Loss from Discontinued Operations, net of tax as the transaction closed on December 22, 2015. 

During the fourth quarter of 2014, we recorded impairment charges for our continuing operations of $256.9 million 
primarily related to Asia Pacific Iron Ore and driven mainly by the changes in life-of-mine cash flows due to declining 
market pricing.  There was also an additional $1.0 billion of impairment charges recorded during the fourth quarter of 
2014 in Loss from Discontinued Operations, net of tax primarily related to Bloom Lake.  Also, during the fourth quarter 
of 2014, we completed the sale of the CLCC assets for $174.0 million in cash and the assumption of certain liabilities, 
of which $155.0 million has been collected, and resulted in a loss on the sale of these assets of $419.6 million.  We 
recorded the results of this sale in our 2014 fourth quarter earnings within Loss from Discontinued Operations, net of tax 
as  historical  North American  Coal  results  are  classified  as  discontinued  operations. The  fourth  quarter  2014  results 
additionally  included  an  income  tax  benefit  of  $207.3  million,  which  includes  the  benefits  related  to  the  continuing 
operations impairment charges.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Board of Directors and Shareholders of 
Cliffs Natural Resources Inc.
Cleveland, Ohio

We have audited the accompanying statements of consolidated financial position of Cliffs Natural Resources 
Inc. and subsidiaries (the "Company") as of December 31, 2015 and 2014, and the related statements of consolidated 
operations, comprehensive income (loss), cash flows, and changes in equity for each of the three years in the period 
ended December 31, 2015. Our audits also included the financial statement schedule listed in the Index at Item 15. 
These financial statements and financial statement schedule are the responsibility of the Company’s management. Our 
responsibility is to express an opinion on the financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board 
(United  States). Those  standards  require  that  we  plan  and  perform  the  audit  to  obtain  reasonable  assurance  about 
whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence 
supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting 
principles used and significant estimates made by management, as well as evaluating the overall financial statement 
presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements present fairly, in all material respects, the financial position 
of Cliffs Natural Resources Inc. and subsidiaries as of December 31, 2015 and 2014, and the results of their operations 
and their cash flows for each of the three years in the period ended December 31, 2015, in conformity with accounting 
principles generally accepted in the United States of America. Also, in our opinion, such financial statement schedule, 
when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material 
respects, the information set forth therein.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the Company's internal control over financial reporting as of December 31, 2015, based on the criteria 
established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of 
the Treadway Commission and our report dated February 24, 2016 expressed an unqualified opinion on the Company's 
internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of
Cliffs Natural Resources Inc.
Cleveland, Ohio

We have audited the internal control over financial reporting of Cliffs Natural Resources Inc. and subsidiaries 
(the “Company”) as of December 31, 2015, based on criteria established in Internal Control - Integrated Framework 
(2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.  The Company’s management 
is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness 
of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control Over 
Financial Reporting.  Our responsibility is to express an opinion on the Company’s internal control over financial reporting 
based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board 
(United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about 
whether effective internal control over financial reporting was maintained in all material respects.  Our audit included 
obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, 
testing  and  evaluating  the  design  and  operating  effectiveness  of  internal  control  based  on  the  assessed  risk,  and 
performing such other procedures as we considered necessary in the circumstances.  We believe that our audit provides 
a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed by, or under the supervision of, the 
company's principal executive and principal financial officers, or persons performing similar functions, and effected by 
the company's board of directors, management, and other personnel to provide reasonable assurance regarding the 
reliability  of  financial  reporting  and  the  preparation  of  financial  statements  for  external  purposes  in  accordance  with 
generally accepted accounting principles. A company's internal control over financial reporting includes those policies 
and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions  and  dispositions  of the assets  of the  company;  (2) provide  reasonable  assurance  that  transactions  are 
recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 
management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection 
of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial 
statements.

Because of the inherent limitations of internal control over financial reporting, including the possibility of collusion 
or improper management override of controls, material misstatements due to error or fraud may not be prevented or 
detected on a timely basis. Also, projections of any evaluation of the effectiveness of the internal control over financial 
reporting  to  future  periods  are  subject  to  the  risk  that  the  controls  may  become  inadequate  because  of  changes  in 
conditions, or that the degree of compliance with the policies or procedures may deteriorate. 

In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting 
as of December 31, 2015, based on the criteria established in Internal Control - Integrated Framework (2013) issued by 
the Committee of Sponsoring Organizations of the Treadway Commission.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board 
(United States), the consolidated financial statements and financial statement schedule as of and for the year ended 
December 31, 2015 of the Company and our report dated February 24, 2016 expressed an unqualified opinion on those 
financial statements and financial statement schedule.

Changes in and Disagreements With Accountants on Accounting and Financial Disclosure

None.

Item 9A.

Controls and Procedures

We maintain disclosure controls and procedures that are designed to ensure that information required to be 
disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified 
in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including 
our President and Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding 
required disclosure based solely on the definition of “disclosure controls and procedures” in Rule 13a-15(e) promulgated 
under the Exchange Act.  In designing and evaluating the disclosure controls and procedures, management recognized 
that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance 
of achieving the desired control objectives, and management necessarily was required to apply its judgment in evaluating 
the cost-benefit relationship of possible controls and procedures.

As of the end of the period covered by this report, we carried out an evaluation under the supervision and with 
the participation of our management, including our President and Chief Executive Officer and our Chief Financial Officer, 
of the effectiveness of the design and operation of our disclosure controls and procedures.  Based on the foregoing, our 
President and Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures 
were effective.

Management's Report on Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting 

as such term is defined under Rule 13a-15(f) promulgated under the Exchange Act.

Internal control over financial reporting is a process designed to provide reasonable assurance regarding the 
reliability  of  financial  reporting  and  the  preparation  of  the  Company's  consolidated  financial  statements  for  external 
purposes in accordance with generally accepted accounting principles. 

Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance 
of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the 
Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit the preparation of 
the consolidated financial statements in accordance with generally accepted accounting principles, and that receipts and 
expenditures of the Company are being made only in accordance with appropriate authorizations of management and 
directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized 
acquisition, use or disposition of the Company's assets that could have a material effect on the consolidated financial 
statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect 
misstatements.  Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls 
may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures 
may deteriorate.

Management  conducted  an  assessment  of  the  Company's  internal  control  over  financial  reporting  as  of 
December 31, 2015 using the framework specified in Internal Control - Integrated Framework (2013), published by the 
Committee of Sponsoring Organizations of the Treadway Commission.  Based on such assessment, management has 
concluded that the Company's internal control over financial reporting was effective as of December 31, 2015.

The effectiveness of the Company's internal control over financial reporting as of December 31, 2015 has been 
audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report that appears 
herein.

February 24, 2016 

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting or in other factors that occurred 
during our last fiscal quarter or our last fiscal year that have materially affected, or are reasonably likely to materially 
affect, our internal control over financial reporting.

Mine Safety Disclosures

Exhibit 95 

The operation of our mines located in the United States is subject to regulation by MSHA under the FMSH 
Act.  MSHA inspects these mines on a regular basis and issues various citations and orders when it believes a violation 
has occurred under the FMSH Act.  We present information below regarding certain mining safety and health citations 
that MSHA has issued with respect to our mining operations.  In evaluating this information, consideration should be 
given to factors such as: (i) the number of citations and orders will vary depending on the size of the mine; (ii) the 
number of citations issued will vary from inspector to inspector and mine to mine, and (iii) citations and orders can be 
contested and appealed and, in that process, are often reduced in severity and amount, and are sometimes dismissed.

Under the Dodd-Frank Act, each operator of a coal or other mine is required to include certain mine safety 
results within its periodic reports filed with the SEC.  As required by the reporting requirements included in §1503(a) 
of the Dodd-Frank Act, we present the following items regarding certain mining safety and health matters, for the period 
presented, for each of our mine locations that are covered under the scope of the Dodd-Frank Act:

(A)  The  total  number  of  violations  of  mandatory  health  or  safety  standards  that  could  significantly  and 
substantially contribute to the cause and effect of a coal or other mine safety or health hazard under 
section 104 of the FMSH Act (30 U.S.C. 814) for which the operator received a citation from MSHA;

(B)  The total number of orders issued under section 104(b) of the FMSH Act (30 U.S.C. 814(b));

(C)  The total number of citations and orders for unwarrantable failure of the mine operator to comply with 

mandatory health or safety standards under section 104(d) of the FMSH Act (30 U.S.C. 814(d));

(D)  The total number of imminent danger orders issued under section 107(a) of the FMSH Act (30 U.S.C. 

817(a));

(E)  The total dollar value of proposed assessments from MSHA under the FMSH Act (30 U.S.C. 801 et seq.); 

(F)  Legal actions pending before the Federal Mine Safety and Health Review Commission involving such 

coal or other mine as of the last day of the period;

(G)  Legal actions initiated before the Federal Mine Safety and Health Review Commission involving such 

coal or other mine during the period; and

(H)  Legal actions resolved before the Federal Mine Safety and Health Review Commission involving such 

coal or other mine during the period.

During the year ended December 31, 2015, our U.S. mine locations did not receive any flagrant violations 
under Section 110(b)(2) of the FMSH Act and no written notices of a pattern of violations, or the potential to have a 
pattern of such violations, under section 104(e) of the FMSH Act. In addition, there were no mining-related fatalities 
at any of our U.S. mine locations during this same period.
