Dear Stockholders, Fiscal 2015 was a year of transition for Wesco Aircraft in many respects. When I joined the company, I already knew Wesco had a strong heritage, a value proposition that customers appreciate, an excellent reputation for service and an outstanding group of employees. There were also gaps in performance, with a need to drive organic growth, operate with greater efficiency and deliver better results. In a very short period of time, we have addressed these gaps head-on, planning and completing actions necessary to build a foundation for change and position our company for the future. In the past two quarters, we have established Wesco’s vision, goals and culture; substantially completed integration activities and aligned our organization to growth channels; taken action to reduce costs; reassessed procurement practices and inventory management; and initiated Policy Deployment to lead and manage performance across the company. We also assessed our industry and confirmed that Wesco’s value proposition remains strong in a growing industry. We believe that Wesco is well placed in major segments of our market, with opportunity to improve our position in others.In fiscal 2015, we began transforming Wesco to reflect our strong competitive position and value proposition in expanding markets, with 74 percent of sales in long-term agreements serving the largest aerospace companies in the world and 26 percent of sales from continued ad hoc demand supporting all of our important customers. By offering our complete product portfolio as one company to the markets we serve, we believe Wesco is better positioned to grow profitably in the future.Net sales in fiscal 2015 were $1,497.6 million, an increase of 10.5 percent compared to $1,355.9 million in fiscal 2014. The net sales increase was driven primarily by the acquisition of Haas Group in fiscal 2014, partially offset by the conclusion of a large commercial contract and the impact of foreign currency movements.We stabilized sales sequentially in the fourth quarter of fiscal 2015 and aligned the sales organization around our three market channels of strategic customers, regional sales and MRO. We are already gaining traction under our new strategy, winning and expanding business with a number of major customers across all regions, products and service categories. In the fourth quarter, we analyzed our inventory and began developing a demand management strategy that links sales, inventory procurement and operations planning. These actions are designed to improve efficiencies, material acquisition costs and working capital as we forecast consumption in line with build and refurbishment rates. We also stabilized selling, general and administrative expenses in the fourth quarter by holding costs in check. We substantially completed the integration of Haas and Wesco and created an organization that we believe will better serve our customers, focus our efforts going to market and enable the company to provide our complete product portfolio and value proposition. During fiscal 2015, we generated robust cash flow, which we used to pay down debt. Cash from operations totaled  $141.2 million in fiscal 2015, compared with $53.7 million in fiscal 2014. We utilized the increased cash to repay approximately $150 million in debt during the year.As we move into fiscal 2016, we are focused on expanding sales prospects with strategic customer accounts through contract renewals, new business and higher production. These customers represent our greatest opportunity to leverage our combined offering and demonstrate Wesco’s global strategic value proposition. In addition, regional sales activities through our branch network devote resources to support the balance of our important customers, leveraging opportunities to drive ad hoc sales and support LTA contracts. Our MRO strategy is using a more focused approach to sales in this critical market through dedicated teams. We took aggressive action in the fourth quarter of fiscal 2015 to address our cost structure and improve efficiencies across all functions, while we continue Wesco’s ongoing commitment to outstanding customer service and delivery performance. At the same time, we are working to drive continuous improvement through our processes, operations and logistics. I want to thank our stockholders, customers and suppliers for their ongoing support of Wesco Aircraft during this period of transition. I also want to express my gratitude to our employees who have worked tirelessly through significant change, and who remain committed to Wesco’s future success and upholding our reputation for service excellence.Sincerely,David J. Castagnola President and Chief Executive OfficerNovember 30, 2015TABLE OF CONTENTS

We are one of the world’s largest distributors and providers of comprehensive supply  chain

management services to the global aerospace industry on an annual  sales  basis. Our services range from
traditional distribution to the management of supplier relationships, quality assurance, kitting,
just-in-time (JIT) delivery and point-of-use  inventory management.  We supply  over 575,000 active stock-
keeping units (SKUs), including C-class  hardware, chemicals, electronic components, bearings, tools and
machined parts. In fiscal 2015, sales of hardware  represented 49% of our net sales, sales of chemicals
represented 40% of our net sales and sales of electronic components represented 7% of our net sales.
We serve our customers under both (1) long-term contractual arrangements (Contracts), which include
JIT contracts, that govern the provision of comprehensive outsourced supply chain management
services and long-term agreements, or LTAs, that typically  set prices for specific  products, and (2) ad
hoc sales. In February 2014, we acquired 100% of the outstanding stock of Haas, a provider of
chemical supply chain management services to the commercial  aerospace, airline, military, automotive,
energy, pharmaceutical and electronics sectors. In July 2012, we acquired substantially all of the  assets
of Interfast, Inc. (Interfast), a Toronto-based value-added distributor of specialty fasteners, fastening
systems and production installation tooling for the aerospace, electronics and general industrial
markets.

Founded in 1953 by the father of our current Chairman of  the  Board of Directors, we have grown

to serve over 8,200 customers, which are primarily in the commercial,  military  and general aviation
sectors, including the leading original equipment manufacturers (OEMs) and their subcontractors,
through which we support nearly all major Western aircraft programs.  We also service industrial
customers, which include customers in the automotive, energy, pharmaceutical and electronics sectors.
We have approximately 2,670 employees and operate across  88 locations in 20 countries. The following

sectors. Chemical sales represented 40%,  26% and 0% of our fiscal 2015, 2014 and 2013 product  sales,
respectively. As a result of our acquisition of Haas, our  chemical product offerings include adhesives;
sealants and tapes; lubricants; oil and  grease; paints and coatings; industrial gases;  coolants and
metalworking fluids; and cleaners and cleaning solvents.

Electronic Components

We offer highly reliable interconnect and electro-mechanical  products, including connectors, relays,
switches, circuit breakers and lighted products. We also offer value-added assembled products  including
mil-circular and rack and panel connectors and illuminated  push button switches. We maintain large
quantities of connector components in inventory, which allows us to respond quickly to customer
orders. In addition, our lighted switch assembly  operation affords customers same day service, including
engraving capabilities in multiple languages.

Bearings

Our product offering includes a variety of standard  anti-friction products designed to both
commercial and military aircraft specifications, such as airframe control bearings,  rod ends, spherical
bearings, ball bearing rod ends, roller bearings and bushings.

Machined Parts and Other

Machined parts are designed for a specific customer and are assigned unique  OEM-specific SKUs.
The machined parts we distribute include laser cut or  stamped brackets, milled parts, shims, stampings,
turned parts and welded assemblies made of materials ranging from high-grade steel or titanium to
nickel based alloys.

We stock a full range of tools needed for the installation of many of our  products, including air
and hydraulic tools as well as drill motors, and we  also offer factory authorized maintenance and repair
services for these tools. In addition to selling these tools, we also rent or lease these tools to our
customers.

Our Services

In addition to our traditional distribution services, we have developed innovative value-added

services, such as quality assurance, kitting  and JIT supply chain management for our customers, and
also sell products to airline-affiliated and  independent maintenance,  repair and overhaul (MRO)
providers.

Hardware

Quality Assurance

Sales of C-class aerospace hardware represented 49%,  62%  and 83% of our fiscal 2015,  2014 and

2013 product sales, respectively. Fasteners, our largest  category of hardware products, include a wide
range of highly engineered aerospace  parts that  are designed  to  hold  together two or more
components, such as rivets (both blind and solid), bolts (including blind bolts), screws, nuts  and
washers. Many of these fasteners are  designed for  use in  specific  aircraft platforms and others can be
used across multiple platforms. Materials used in the manufacture of these fasteners range from
standard alloys, such as aluminum, steel or stainless steel, to  more advanced materials, such as
titanium, Inconel and Waspalloy.

Chemicals

On February 28, 2014, we acquired Haas, a provider of chemical supply  chain management  services

to the commercial  aerospace, airline,  military,  automotive,  energy, pharmaceutical and  electronics

Our quality assurance (QA) function is a  key component of our service offering, with 6%  of our
employees dedicated to this area. We believe we offer an industry-leading QA  function as a  result of
our rigorous processes, sophisticated testing equipment and dedicated  QA staff.  Our superior QA
performance is demonstrated by a comparison of our  customers’ aggregate  rejection rate of the
products we deliver, which was 0.11% during fiscal 2015, to our  rejection  rate of the products we
receive from our suppliers, which was 2.94% during  fiscal 2015.

Our QA department inspects the inventory  we purchase to ensure the accuracy  and completeness

of documentation. For many of our customers,  these inspections are conducted at our in-house
laboratory, where we operate sophisticated testing equipment. We also maintain  an electronic copy of
the relevant certifications for the inventory, which  can include a manufacturer certificate of
conformance, test reports, process certifications, material distributor certifications and raw  material mill
certifications. Our industry-leading QA capabilities also allow our JIT customers to reduce  the number

6

7

of personnel dedicated to the QA function and reduce  the delays  caused by the rejection of improperly
inspected products.

Kitting

Kitting involves the packaging of an  entire bill  of  materials  or a complete  ‘‘ship-set’’ of products,
which  reduces the amount of time workers spend retrieving  products from  storage locations. Kits can
be customized in varying configurations  and  sizes and can  contain up  to  several  hundred different
products. All of our kits and components contain  fully certified and  traceable products and are
assembled by our full-service kitting department at our Central Stocking Locations (CSLs), or at  our
customer sites.

JIT Supply Chain Management

JIT supply chain management involves the delivery  of  products  on an as-needed basis  to  the
point-of-use at a customer’s manufacturing line. JIT  programs are designed to prevent  excess inventory
build-up and shortages and improve manufacturing efficiency. Each JIT contract  requires us to
maintain an efficient inventory tracking,  analysis and replenishment  program and is  designed to provide
high levels of stock availability and on-time delivery. We believe  customers  that  utilize our
comprehensive JIT supply chain management services  are frequently able to realize significant benefits
including:

• reduced inventory levels and lower  inventory excess and obsolescence (E&O)  expense, in  part
because such customers only purchase what they need,  and make more efficient  use of their
floor space;

• increased accuracy in forecasting and planning,  resulting in substantially  improved on-time

delivery, reduced expediting costs and fewer disruptions  of production schedules;

• improved quality assurance resulting in a substantial reduction in customer product rejection

rates;  and

• reduced administrative and overhead costs  relating  to  procurement, QA, supplier management

and stocking functions.

Before signing a JIT contract, our customers typically experience outages of  many SKUs and,  in
some cases, have up to a year’s worth of  inventory on hand. As part of our  JIT programs, we  generally
assume the customer’s existing inventory  at the onset of the contract, immediately  reducing  their
inventory on-hand and the associated management  costs. Customer inventory is generally assumed  on a
consignment basis and is entered in our  database in a distinct customer-specific ‘‘virtual warehouse.’’
Software protocol in our IT systems requires the system to first  ‘‘look’’ to a customer’s consigned
inventory when parts replenishment is required.  In certain  cases, we  can sell this consigned inventory to
our  base of over 8,200 other active customers around the world, gradually drawing down the customer’s
inventory. As the consigned inventory for  each SKU is  exhausted, our stock  of  Wesco-sourced product
reserve  is then used for replenishment.

Another key strength of our JIT programs is our ability  to utilize  highly scalable  and customizable

point-of-use systems to develop an efficient  supply chain  management system  and automated
replenishment solution for any number of  SKUs. In order  to minimize inventory on hand,  certain
indicators are used to trigger the replenishment of product from a supplying location to the  location of
consumption. Our ‘‘Twin-Bin’’ system  is  an  example  of such an indicator. A JIT program designed
around a Twin-Bin system utilizes a specially-manufactured unit  composed of two  bins stacked on  top
of one another. In this system, a clear plastic bag, typically  containing a 30-day supply  of parts,  is
loaded in each bin. Production workers  use all of  the parts  within the  bottom bin before drawing a
pullout slide between the two bins that drops  the full plastic  bag of parts from the  top bin  into  the

bottom bin. An empty top bin indicates the need to initiate  replenishment of the parts and provides a
clear visual management process on the manufacturing floor. All replenishment activity is done via
hand-held scanners that transmit orders to our stocking locations.

In certain circumstances, we also provide our JIT customers with additional value-added services,

including the implementation of process control and usage reduction programs; support for
environmental, health and safety compliance (EHS)  and reporting; and assistance  with the development
of waste management strategies.

MRO Sales

We sell products to airline-affiliated, OEM-affiliated and independent  MRO providers on both a

Contract  and ad hoc basis. We have recently expanded  our efforts  to  increase our presence in both the
commercial and military aerospace MRO markets, particularly as a result of our acquisition of Interfast
in 2012, our acquisition of Haas in 2014 and  through the introduction of  our Wesco e-commerce sales
platform, which we believe provides us with a  cost-effective way to further penetrate the MRO market.
In addition, we have targeted domestic and international airlines and maintenance centers that we
believe are assuming an expanded role  within the  MRO market.

Going forward, we expect commercial MRO providers to benefit from the same trends as those
impacting the commercial OEM market, including increased revenue passenger miles, which in turn
should  drive growth in the commercial fleet  and greater utilization of existing  aircraft. The commercial
MRO market may also benefit from directives  or notifications announced by international industry
regulators and trade associations. Such  directives or notifications can serve to bolster required
maintenance, and thus the demand for new and existing  aerospace products. In addition, the retirement
of certain older and less fuel-efficient aircraft models has been deferred  as a result of the recent
decrease in global oil prices, which we believe could drive growth in the MRO market. Furthermore,
we expect demand in the military MRO market to be driven by requirements to maintain aging military
fleets, changes in the overall fleet size and the level of U.S. military  activity overseas. We believe that
our presence in this market helps us  mitigate  the volatility of new military aircraft sales with sales to
the aftermarket.

Customer Contracts

We sell products to our customers under two types of arrangements: (1) Contracts, which include

JIT supply chain management contracts  and LTAs, and (2) ad hoc sales.

Contracts

JIT Contracts.

JIT contracts are typically three to five years in length  and are structured to supply

the product requirement for specific SKUs, production lines or facilities. Given our direct involvement
with JIT customers, volume requirements and purchasing frequency under these  contracts is highly
predictable. Under JIT contracts, customers commit to purchase specified  products from us at a  fixed
price or a pass-through price, on an if-and-when needed  basis, and we  are responsible for maintaining
high levels of stock availability of those products. JIT  contracts  typically contain termination for
convenience provisions, which generally allow our customers  to  terminate  their  contracts on short
notice without meaningful penalties, provided  that we are reimbursed for the cost of any inventory
specifically procured for the customer.  JIT customers often purchase products from us that are not
covered under their contracts on an  ad  hoc  basis. For additional information about our JIT supply
chain management services, see ‘‘—Our Products and Services—Our Services—JIT Supply Chain
Management.’’

LTAs. Like JIT contracts, LTAs also typically run for three to five  years.  LTAs are  essentially

negotiated price lists for customers or  individual customer sites that cover a range of pre-determined

8

9

products, purchased on an as-needed  basis.  LTAs generally obligate  the customer  to  buy contracted
SKUs from us and may obligate us to  maintain  stock availability for those  products. Once  an LTA is in
place, the customer is then able to place  individual  purchase  orders  with us for any of the contractually
specified products. LTAs typically contain termination for convenience  provisions, which generally allow
for our  customers to terminate their  contracts on short notice without  meaningful penalties, provided
that we are reimbursed for the cost of any inventory specifically procured for the customer. LTA
customers also frequently purchase products from  us on an ad  hoc  basis,  which  are not captured  under
the pricing arrangement.

Ad Hoc Sales

Ad hoc customers purchase products from  us on an as-needed basis  and are generally supplied out

of our existing inventory. Typically, ad hoc orders are for smaller quantities of products than those
ordered under Contracts, and are often urgent in nature. Given our  breadth and  volume of inventory,
it is not uncommon for even our competitors to purchase products  from  us on  an ad  hoc  basis when
their own stocks prove to be inadequate. In  an environment of increasing aircraft  production,  product
shortages can become increasingly common  for  OEMs, subcontractors, MRO providers and distributors
with less sophisticated forecasting abilities  and  procurement organizations.

Under each of the sales arrangements  described above  we typically  warrant that the  products we

sell conform to the drawings and specifications that are in effect at the time of delivery  in the
applicable contract, and that we will  replace defective or  non-conforming  products for a period of time
that varies from contract to contract.  The product manufacturer,  in turn, typically indemnifies us for
liabilities resulting from defective or non-conforming products. We do not  accrue for warranty expenses
as our claims related to defective and non-conforming  products have  been nominal.

We  believe that backlog is not a relevant  measure of our business, given the  long-term nature of

our  Contracts with our customers.

Customers

We  sell to over 8,200 active customers worldwide.  During  fiscal 2015, no single  customer

represented more than 10% of our net  sales, and only two customers  accounted for over 5% of  our net
sales, with each consisting of multiple  independent programs. Our top 10  customers collectively
accounted for 44% of our net sales during  fiscal  2015.

Seventy-five percent of our fiscal 2015 net sales were derived from major  OEMs, such  as Airbus,
Alenia, Boeing, BAE Systems, Bell Helicopter,  Bombardier, Cessna, Embraer, Gulfstream, Lockheed
Martin, Northrop Grumman and Raytheon, and  certain of their subcontractors. Government sales
comprised 14% of our net sales during  fiscal 2015 and were derived from various military  parts
procurement agencies such as the U.S.  Defense Logistics Agency, or from  defense  contractors buying
on their behalf. Aftermarket sales to  airline-affiliated or independent MRO providers made up  7% of
our  fiscal 2015 net sales. The remaining 4% of our  net sales  are  to  other  distributors  on an  ad hoc
basis.

During  fiscal 2015, 61% of our net sales were  derived from customers supporting  commercial

programs and 39% of our net sales were derived from customers  supporting  military programs.  Our
customers are principally located in the  United  States, with shipments to customers  in the United
States comprising 74% of our net sales  during fiscal 2015.  We also service international customers in
markets that include Australia, Canada,  China, France, Germany, India, Ireland, Israel, Italy, Malaysia,
Mexico, Philippines, Poland, Saudi Arabia, Singapore, South Korea, Turkey  and the  United Kingdom.
For additional information about our net  sales and  long-lived assets by geographic area, see Note  21  of
the Notes to Consolidated Financial  Statements in Part  II, Item 8 of this Annual Report on  Form  10-K.

Procurement

We source our inventory from over 4,290 suppliers, including Precision Castparts Corp., Alcoa
Fastening Systems, PPG, Monogram Aerospace  Fasteners, Henkel Corp., 3M,  Lisi Aerospace, Cass
Information Systems Inc., Chemtura Corporation and Bristol Industries. During fiscal 2015,  Precision
Castparts Corp. and Alcoa Fastening Systems supplied 13% and  9%,  respectively, of the products we
purchased. Suppliers typically prefer to deal with a relatively small number of large and sophisticated
distributors in order to improve machine utilization; reduce finished goods inventory and related
obsolescence costs; maintain pricing discipline; improve  performance  in meeting on-time-delivery
targets to end customers; and consolidate customer  accounts, which can reduce administrative and
overhead costs relating to sales and marketing, customer  service and  other  functions. As a result  of the
scale of our operations and our long-standing relationships with many of our suppliers, we are often
able to take advantage of significant volume-based discounts when purchasing inventory.  Given our
industry position, financial strength and philosophy of cooperation  with suppliers, we believe we are in
an excellent position to become a distributor for new product lines as they become available.

Our management analyzes supply, demand, cost and pricing factors to make inventory investment

decisions, which are facilitated by our  highly customized IT systems, and we maintain close
relationships with the leading suppliers in  the industry. Our  strong understanding of the global
aerospace industry is derived from our long-term relationships with major OEMs,  subcontractors and
suppliers. In addition, our direct insight into our customers’ production  rates  often  allows us to detect
industry trends. Furthermore, our ability  to  forecast demand and place purchase orders with our
suppliers well in advance of our customer requirements can provide us with a distinct advantage in an
industry where inventory availability is critical for customers that need specific products within a
stipulated timeframe to meet their own production and delivery commitments. However, despite  our
expertise in this area, effective inventory management is  an ongoing challenge, and we continue to take
steps to enhance the sophistication of  our procurement practices and mitigate  the  negative impact of
inventory builds on our cash flow. For additional  information about the impact of  inventory on our
business, including our cash flows, see Part I, Item 1A.  ‘‘Risk Factors—Risks Related to Our Business
and Industry—We may be unable to effectively  manage our inventory, which could have a material
adverse effect on our business, financial condition  and results of operations,’’ Part II,
Item 7. ‘‘Management’s Discussion and Analysis of Financial Condition and Results  of Operations—
Other Factors Affecting Our Financial Results—Fluctuations  in Cash Flow,’’ and Part II,
Item 7. ‘‘Management’s Discussion and Analysis of Financial Condition and Results  of Operations—
Critical Accounting Policies and Estimates—Inventories.’’

Information Technology Systems

We have invested to build integrated, highly customized IT systems that enable our purchasing and

sales organization to make more informed  decisions, our inventory management system to operate in
an efficient manner and certain of our customers to make online purchases directly from us.  Our
primary scalable IT infrastructure is based on IBM and  Oracle servers, the Oracle Enterprise database
and the Oracle JD Edwards EnterpriseOne (JDE), enterprise resource planning  (ERP) system. Our
chemical supply chain management system, tcmIS, is a proprietary system,  developed using the Oracle
Enterprise database. These customized IT systems provide us  visibility into inventory quantities,
stocking locations and purchases across our customer base by individual SKU, enabling us to accurately
fill 16,000 orders per day and provide an exceptional level of customer  service. These systems are fully
capable of interfacing with external business systems, including Oracle, SAP, Microsoft and others, and
we have developed additional functionality for JIT  delivery and  direct line feed of certain of the
products we sell. This functionality includes recognition of signals and actions to fill customer bins from
hand-held scanners, min/max data or  proprietary signals from a customer’s ERP system. JDE and
tcmIS also support our EDI functionality, which allows our system to interface  with customers and

10

11

suppliers, regardless of technology, data format or  connectivity. TcmIS also  supports additional
chemical-specific functionality, such as product labeling and Global Harmonized System compliance.

For our shipping logistics and export  compliance  support, we employ Precision  Software’s TRA/X.
TRA/X enables us to ship globally while  maintaining tracking numbers and rating information for  each
customer shipment. In addition, at several of our  distribution facilities, we use Minerva’s AIMS
inventory management system in order to provide the  best possible warehouse  flow and cycle times.
AIMS is tailored to fit our global warehouse  operational needs and  allows us to provide an  expandable
warehouse management system that can  also  incorporate transaction processing,  work-in-progress  and
other manufacturing operations. AIMS interfaces  with a  broad range of material handling  equipment,
including horizontal and vertical carousels, conveyors, sorting equipment, pick systems and  cranes.

Competition

The industry in which we operate is highly competitive and  fragmented. We believe  the principal

competitive factors in our industry include the  ability  to  provide superior  customer service and support,
on-time delivery, sufficient inventory  availability, competitive pricing and an effective QA  program. Our
competitors include both U.S. and foreign  companies,  including divisions  of larger companies  and
certain of our suppliers, some of which  have significantly greater financial resources than we  do, and
therefore may be able to adapt more  quickly to changes in customer requirements than we can. In
addition to facing competition for Contract customers from our primary competitors, Contract
customers or potential Contract customers  may  also determine that it  is more  cost effective to establish
or re-establish an in-house supply chain  management  system. Under these  circumstances, we may  be
unable to sufficiently reduce our costs in order to provide competitive  pricing  while also  maintaining
acceptable operating margins.

Employees

As of September 30, 2015, we employed approximately 2,670 personnel worldwide, 865 of which

were located at customer sites. We have 799 employees located outside of North America. We are  not
a party to any collective bargaining agreements  with our employees.

Regulatory Matters

Governmental agencies throughout the world, including the U.S. Federal Aviation Administration

(the FAA), prescribe standards for aircraft components, including  virtually all commercial  airline and
general aviation products, as well as  regulations regarding the repair and overhaul of  airframes  and
engines. Specific regulations vary from  country to country, although compliance with FAA  requirements
generally satisfies regulatory requirements in  other  countries. In addition, the products we distribute
must also be certified by aircraft and engine OEMs. If any of the material authorizations  or approvals
that allow us to supply products is revoked or  suspended, then the  sale of  the related products would
be prohibited by law, which would have  an adverse  effect  on our  business, financial condition and
results of operations.

From time to time, the FAA or equivalent regulatory agencies  in other countries propose new

regulations or changes to existing regulations, which are usually more  stringent than existing
regulations. If these proposed regulations  are adopted and enacted, we could incur significant
additional costs to achieve compliance,  which could have  a material adverse effect on our business,
financial condition and results of operations.

We  are also subject to government rules and regulations that include the  U.S. Foreign Corrupt
Practices Act (the FCPA), the Bribery Act 2010 (the Bribery Act), the International  Traffic in Arms
Regulations (ITAR), the Export Administration  Regulations  (EAR), economic  sanctions and the False
Claims Act. See ‘‘Risk Factors—Risks Related to Our Business and Industry—We are  subject to unique

business risks as a result of supplying equipment and services to the  U.S. government directly and as a
subcontractor, which could lead to a reduction  in our net sales from, or the profitability of our supply
arrangements with, the U.S. government’’ and ‘‘—Our international operations require us to comply
with numerous applicable anti-corruption and  trade control laws and regulations, including those of the
U.S. government and various other jurisdictions, and our failure to comply with these laws and
regulations could adversely affect our reputation, business,  financial condition and results of
operations.’’

Environmental Matters

We are subject to extensive federal, state, local and foreign laws, regulations, rules and ordinances

relating to pollution, protection of the environment and human  health and safety, and the handling,
transportation, storage, treatment, disposal and remediation of hazardous substances, including
potentially with respect to historical chemical blending and other activities that pre-dated our purchase
of Haas. Actual or alleged violations of EHS laws, or permit requirements could result in restrictions or
prohibitions on operations and substantial civil  or criminal  sanctions, as well as, under some EHS laws,
the assessment of strict liability and/or joint and several liability.

Furthermore, we may be liable for the costs of investigating and  cleaning up environmental
contamination on or from our operations or at off-site locations, including potentially with respect to
historical chemical blending and other activities that pre-dated our purchase of our businesses. We may
therefore incur additional costs and expenditures beyond those currently anticipated to address all such
known and unknown situations under existing  and future EHS laws.

In addition, governmental, regulatory  and societal demands for increasing levels of product safety
and environmental protection could result in  increased pressure  for more stringent regulatory control
with respect to the chemical industry. For example, the Hazard Communication Standard promulgated
by the U.S. Occupational Safety and Health Administration is now aligned with the Globally
Harmonized System of Classification  and Labeling of Chemicals, which requires  our  suppliers to make
revisions to labels and safety data sheets. Changes in the regulatory environment,  particularly, but not
limited to, in the United States, the European Union, Canada and China, could lead to heightened
regulatory scrutiny and could adversely impact our ability to supply certain products and/to provide
chemical management services to our customers. For instance, the August 2015 explosion at the port of
Tianjin, China, may lead to stricter chemical safety standards in that country. The European Union’s
Registration, Authorization and Restriction of Chemicals (‘‘REACH’’ and analogous non-E.U. laws and
regulations), or other similar laws and  regulations, also could result in compliance obligations,  fines,
ongoing monitoring and other future business activity restrictions, which could have a material adverse
effect on the Company’s liquidity, financial position and results of operations.

ITEM 1A. RISK FACTORS

You should consider and read carefully all  of the risks and  uncertainties described below, as well as

other information included in this Annual Report, including our  consolidated financial statements  and
related notes. The risks described below  are not the only ones  facing  us. The occurrence of any of the
following risks or additional risks and uncertainties not presently known to  us or that we currently believe to
be immaterial could materially and adversely affect our business, financial condition or results of operations.
This  Annual Report also contains forward-looking statements and estimates that involve  risks and
uncertainties. Our actual results could  differ  materially  from  those anticipated in the  forward-looking
statements as a result of specific factors, including the risks  and uncertainties described below.

Risks Related to Our Business and Industry

We are directly dependent upon the condition of the aerospace  industry,  which  is closely  tied to global
economic conditions, and if the volatility  in the global financial  markets were to result in  a slowdown in the
current economic recovery or a return to  a recession, our  business, financial condition and results of
operations could be negatively impacted.

Demand  for the products and services we offer are directly tied to the delivery  of new aircraft,

aircraft utilization, and repair of existing  aircraft, which,  in turn, are  impacted by global economic
conditions. For example 2009, revenue  passenger miles (RPMs)  on commercial aircraft declined due to
the global recession. During the same  period, the  industry  experienced declines in  large commercial,
regional and business jet deliveries. While  demand for  commercial and regional jets  has fully  recovered,
business jet orders and deliveries have recovered more  slowly. A  slowdown  in the global  economy, or  a
return  to a recession, would negatively  impact the aerospace industry, and could negatively  impact  our
business, financial condition and results  of operations.

Military spending, including spending on  the products we  sell, is  dependent upon national defense budgets,
and a reduction in  military spending could have a material adverse  effect on our  business, financial condition
and results of operations.

During  the year ended September 30, 2015, 39%  of  our net sales were related to military aircraft.

The military market is significantly dependent upon government  budget trends,  particularly the U.S.
Department of Defense (DoD) budget.  Future  DoD  budgets could be negatively  impacted  by  several
factors, including, but not limited to,  a change in  defense  spending policy by the current and  future
presidential administrations and Congress, the U.S. government’s  budget deficits, spending priorities,
the cost of sustaining the U.S. military  presence  in overseas operations  and  possible  political pressure
to reduce U.S. Government military spending,  each of which  could cause the DoD budget to decline.  A
decline  in U.S. military expenditures  could  result in a  reduction in military aircraft  production, which
could have a material adverse effect  on  our business, financial condition and results  of operations.

In particular, military spending may be negatively impacted by the  Budget Control Act of  2011
(the Budget Control Act), which was passed in August 2011.  The  Budget  Control Act  established limits
on U.S. government discretionary spending, including  a reduction  of defense  spending  by  approximately
$490 billion between the 2012 and 2021 U.S. government fiscal years, and also provided that the
defense budget would face ‘‘sequestration’’ cuts of up to an  additional $500  billion during that same
period to the extent that discretionary spending limits were exceeded. The impact of sequestration was
reduced with respect to the government’s 2014 and  2015 fiscal years, in  exchange for extending
sequestration into fiscal years 2022 and  2023, following the enactment of the Bipartisan Budget  Act  of
2013 in December 2013. The impact  of sequestration  was  further reduced  with respect to the
government’s 2016 and 2017 fiscal years, following the enactment of the Bipartisan Budget  Act of 2015
in November 2015. Sequestration is currently  scheduled  to  resume  in the  government’s 2018  fiscal year.
We  are unable to predict the impact the  cuts associated  with Sequestration will ultimately have on

funding for the military programs which we support. However,  such cuts could  result in  reductions,
delays or cancellations of these programs, which could have a material adverse effect on  our business,
financial condition and results of operations.

We are subject to unique business risks as a result of supplying equipment  and services  to the U.S. government
directly and as a subcontractor, which could lead to  a reduction in  our  net  sales from, or the profitability of
our supply arrangements with, the U.S.  government.

Companies engaged in supplying defense-related  equipment and services to U.S. government
agencies are subject to business risks specific to the defense industry. We  contract directly with the U.S.
government and are also a subcontractor to customers  contracting with the U.S. government.
Accordingly, the U.S. government may unilaterally suspend or prohibit us  from receiving new contracts
pending resolution of alleged violations of procurement laws  or regulations, reduce the value of existing
contracts or audit our contract-related costs and  fees.  In addition, most of our U.S. government
contracts and subcontracts can be terminated by the U.S. government or the  contracting party, as
applicable, at its convenience. Termination for convenience provisions provide only for our recovery of
costs incurred or committed, settlement expenses and  profit on the work completed prior to
termination.

In addition, we are subject to U.S. government inquiries and  investigations, including periodic
audits of costs that we determine are reimbursable under government  contracts. U.S. government
agencies routinely audit government contractors to review performance under contracts, cost structure
and compliance with applicable laws, regulations, and  standards, as well as the adequacy of and
compliance with internal control systems and policies. Any  costs  found to  be  misclassified  or
inaccurately allocated to a specific contract are not reimbursable, and to the extent already reimbursed,
must be refunded. Also, any inadequacies in our systems and policies could result in payments  being
withheld, penalties and reduced future business.

We are also subject to the federal False  Claims  Act, which provides for substantial civil penalties

and treble damages where a contractor presents a false or fraudulent claim to the government for
payment. Actions under the False Claims Act may be brought by the government or by other persons
on behalf of the government (who may then share in any recovery).

We do not have guaranteed future sales of the products we sell and when we enter into Contracts with our
customers we generally take the risk of  cost overruns, and our business, financial condition, results of
operations and operating margins may be negatively affected if we purchase more products than our
customers require, product costs increase unexpectedly, we experience high start-up costs on new Contracts or
our Contracts are terminated.

A majority of our Contracts are long-term, fixed-price agreements with no guarantee of future
sales volumes, and they may be terminated for convenience on short notice by our customers, often
without meaningful penalties, provided that we are reimbursed for the cost of any inventory specifically
procured for the customer. In addition,  we purchase inventory  based on  our  forecasts of anticipated
future customer demand. As a result,  we may take the risk  of  having excess inventory  in the event that
our customers do not place orders consistent with our forecasts, particularly with respect  to  inventory
that has a more limited shelf-life. We also run the  risk of not being  able to  pass  along or otherwise
recover unexpected increases in our  product costs, including  as a result of commodity price increases,
which may increase above our established  prices at the time we  entered into the Contract and
established prices for products we provide. When we are awarded new Contracts, particularly JIT
contracts, we may incur high costs, including salary and overtime costs to hire and train on-site
personnel, in the start-up phase of our performance. In the event that we purchase more products than
our customers require, product costs increase unexpectedly,  we experience  high start-up  costs on new

14

15

Contracts or our Contracts are terminated, our business,  financial  condition, results  of operations  and
operating margins could be negatively  affected.

If we lose significant customers, significant  customers materially  reduce their purchase orders  or significant
programs on which  we rely are delayed,  scaled back  or eliminated, our business, financial condition and
results of operations may be adversely affected.

Our top ten customers for the year ended September  30, 2015 accounted for  44% of our net sales.

A reduction in purchasing by or loss  of one of our larger customers for  any  reason, including changes
in manufacturing or procurement practices, loss of a  customer as a result  of the acquisition of such
customer by a purchaser who does not fully utilize  a distribution model or uses a competitor,
in-sourcing by customers, a transfer of business to a  competitor,  an economic  downturn, failure to
adequately service our clients, decreased production  or a strike, could have a  material  adverse  effect  on
our  business, financial condition and results of operations.

As an example of changes in manufacturing  practices  that  could  impact us,  OEMs such  as Boeing
and Airbus are currently incorporating  an  increasing  amount  of composite materials in the  aircraft they
manufacture. Aircraft utilizing composite  materials generally  require  the use  of  significantly  fewer
C-class aerospace parts than new aircraft  made of  more traditional non-composite materials,  although
the parts used are generally higher priced than  C-class aerospace  parts  used  in non-composite aircraft
structures. As Boeing, Airbus and other  customers  increase their reliance  on composite materials,  they
may materially reduce their purchase orders from us.

As an example of the potential loss of business due to customer  in-sourcing, a major  OEM is
undertaking an initiative to cause its first and second tier suppliers  to  source certain OEM-specific
materials, including fasteners, directly from the OEM  itself, rather than through distributors such as us.
If such initiative is broadly implemented  by the OEM, or if other OEMs  pursue similar initiatives, a
portion of our sales to their suppliers, and consequently our business, financial condition and results  of
operations, could be adversely affected.

We  expect to derive a significant portion of  our net  sales  from certain aerospace programs in their

early production stages. In particular,  our future growth will  be  dependent,  in part,  upon our sales to
various OEMs and subcontractors. If  production of  any of the  programs  we support  is terminated  or
delayed, or if our sales to customers  affiliated  with these programs are reduced or  eliminated, our
business, financial condition and results  of operations could be adversely affected.

In addition, during fiscal 2014, we modified and extended a contract with  an existing customer that

resulted in a $66.3 million reduction  in net sales to the customer during fiscal 2015  compared to fiscal
2014.

We operate in a highly competitive market and our failure to compete effectively may negatively  impact our
results of operations.

We  operate in a highly competitive global industry and compete against a number of companies,

including divisions of larger companies and certain of our suppliers, some  of which may  have
significantly greater financial resources than  we do, and therefore may be able  to  adapt more quickly to
changes in customer requirements than  we can. Our  competitors consist of both  U.S. and foreign
companies and range in size from divisions of large public corporations to small privately  held entities.
We  believe that our ability to compete depends  on superior customer service  and support, on-time
delivery, sufficient inventory availability,  competitive pricing and  effective quality assurance programs.
In order to remain competitive, we may have to adjust the prices of  some of the  products and services
we sell and continue investing in our procurement, supply-chain management and  sales and marketing
functions, the costs of which could negatively impact  our  results of operations.

In addition, we face competition for our Contract customers from both competitors  in our industry

and the in-sourcing of supply-chain management by our customers themselves. If any of our Contract
customers decides to in-source the services we provide or switch to one of our competitors, we would
be adversely affected.

We may be unable to effectively manage our inventory, which  could have  a material adverse effect on our
business, financial condition and results of operations.

Due to the lead times required by many of our suppliers,  we typically order products, particularly

hardware products, in advance of expected sales, and the volume of such orders may be significant.
Lead times generally range from several weeks up to two years, depending  on industry conditions,
which makes it difficult to successfully manage our inventory as we plan for future demand. In  addition,
demand for our products can fluctuate  significantly,  which can also negatively impact our cash flows
and inventory management. For example, we believe  that the strategic inventory purchases we made
during fiscal 2013, 2014 and 2015, combined with lower than expected demand and a lack of discipline
around our inventory planning process, negatively impacted our cash  flows.  In  addition, we may choose
to dispose of slow-moving inventory in the future if we determine that the market and economics make
it prudent to do so. For example, in the three  months ended September 30, 2015, we determined that
inventory previously purchased in connection with a specific program which was subsequently
terminated, to have no alternative use, and we recorded  a reserve  of $33.0 million for such inventory.
In the fourth quarter of 2015, management implemented a new strategy of providing integrated supply
chain services more tailored to customer demand through long-term contracts and focused forecasted
consumption, including changes to our inventory purchasing strategy,  holding  inventory for shorter
periods and the planned scrapping of long dated inventory. The  new strategy and updates for fiscal
2015 sales activities led to changes in the sell through  rates, holding  period of aged inventory and
others estimates used in the E&O reserve  for our hardware inventory, which increased our E&O
inventory reserves by $43.8 million. If we are  unable to effectively manage our inventory, our cash  flows
may be negatively affected, which could  have a material adverse effect on our business, financial
condition and results of operations.

If suppliers are unable to supply us with the products we sell in a  timely manner, in adequate quantities
and/or at a reasonable cost, we may be  unable to meet the demands of our customers, which could have a
material adverse effect on our business, financial condition and results of operations.

Our inventory is primarily sourced directly from  producers and manufacturing firms, and we
depend on the availability of large supplies of the products  we sell. Our largest supplier for the year
ended September 30, 2015 was Precision Castparts Corp. During fiscal  2015, 13% of the products we
purchased were from Precision Castparts Corp. and 9% were purchased from Alcoa Fastening Systems.
In addition, our ten largest suppliers during  fiscal 2015 accounted  for 32%  of our purchases. These
manufacturers and producers may experience capacity constraints that result in their being unable to
supply us with products in a timely manner, in adequate quantities and/or at a  reasonable cost.
Contributing factors to manufacturer capacity constraints  include, among other things, industry or
customer demands in excess of machine capacity, labor  shortages  and changes in raw material flows.
Any significant interruption in the supply of these  products  or termination  of our relationship with any
of our suppliers could result in us being unable to meet the demands of our customers, which would
have a material adverse effect on our business, financial condition and results of operations.

We may be unable to fully integrate the Haas business and may encounter  significant unexpected difficulties as
we work to fully integrate the two businesses.

On February 28, 2014, we completed the Haas acquisition. Prior  to  the acquisition, Wesco and

Haas were independent organizations, each utilizing different systems, controls, processes and

16

17

procedures. Following completion of the  Haas acquisition, our ability  to  fully realize  the anticipated
benefits of the acquisition of Haas depends, to a large extent, on our  ability to fully integrate the  Haas
business. The combination of two independent  enterprises is a complex, costly and  time-consuming
process. The complexion of the overall integration may result in  unanticipated problems, expenses,
liabilities, loss of client relationships,  expenditure of  resources and  distraction of management and
personnel. The difficulties of completing  the combination  of  the operations include:

• we may not realize any or all of the  potential benefits of the acquisition of Haas  that  could

result from combining the businesses of Wesco and Haas;

• the acquisition of Haas could have  an adverse impact on our  relationships  with employees,

customers and suppliers, and prospective customers or  other  third parties may delay or decline
entering into agreements with us as a result of the acquisition;

• management’s attention may be diverted to integration matters;

There are risks inherent in international operations that could have a material adverse effect on our business,
financial condition and results of operations.

While the majority of our operations  are based in the United States,  we have significant

international operations, with facilities  in Australia, Canada, China, France, Germany, India, Ireland,
Israel, Italy, Malaysia, Mexico, Philippines, Poland, Saudi  Arabia, Singapore, South Korea, Turkey and
the United Kingdom, and customers throughout North America, Latin America, Europe, Asia and the
Middle East. For the years ended September 30, 2015 and 2014, 34% and 43%, respectively, of our net
sales were derived from customers located outside the United States.

Our international operations are subject to, without limitation, the following risks:

• the burden of complying with multiple and possibly conflicting laws and any unexpected changes

in regulatory requirements;

• political risks, including risks of loss due to civil  disturbances,  acts of  terrorism, acts of war,

• we may continue to devote significant additional resources to integration;

guerilla activities and insurrection;

• we may not be able to achieve anticipated cost savings and synergies;

• unstable economic, financial and market conditions and increased expenses as a result  of

• we may have additional difficulties  integrating financial accounting systems, internal controls and
standards, procedures and policies (including with  respect to Sarbanes-Oxley Act compliance);

• the assumptions both Wesco and Haas have made regarding  critical  accounting estimates could

be incorrect;

• integration of our IT systems; and

• integration of our trade compliance function.

Our business is highly dependent on complex  information technology.

The provision and application of IT  is an increasingly  critical aspect of our business. Among other

things, our IT systems must frequently interact  with those  of our  customers,  suppliers and  logistics
providers. Our future success will depend on our  continued ability  to  employ IT systems that meet our
customers’ demands. The failure or disruption of the  hardware or software that supports our IT
systems, including redundancy systems, could significantly harm  our ability  to  service  our customers and
cause  economic losses for which we could  be  held  liable and which could damage our reputation.

Our competitors may have or may develop IT  systems that permit them to  be  more cost effective

and otherwise better situated to meet customer  demands  than IT  systems we  are able  to  acquire or
develop. Larger competitors may be able  to develop or license IT systems more  cost effectively  than we
can by spreading the cost across a larger revenue base, and competitors  with greater financial  resources
may be able to acquire or develop IT systems  that we  cannot afford. If we fail to meet  the demands of
our  customers or protect against disruptions of our IT systems,  we  may  lose  customers,  which could
seriously harm our business and adversely affect our  operating results and  operating cash flow.

We may  be unable to retain personnel who are  key to our  operations.

Our success, among other things, is dependent on our  ability  to  attract, develop and retain highly
qualified senior management and other key personnel. Competition  for key personnel is  intense,  and
our  ability to attract and retain key personnel  is dependent  on a number of  factors, including prevailing
market conditions and compensation  packages offered by companies competing for the same talent.
The inability to hire, develop and retain  these key employees  may  adversely affect our operations.

inflation, or higher interest rates;

• difficulties in enforcement of third-party contractual obligations and  collecting receivables

through foreign legal systems;

• difficulties in staffing and managing international operations and the  application of foreign labor

regulations;

• differing local product preferences and product requirements; and

• potentially adverse tax consequences  from changes in tax  laws, requirements relating to

withholding taxes on remittances and other payments by subsidiaries and restrictions on our
ability to repatriate dividends from our  subsidiaries.

In addition, fluctuations in the value of  foreign currencies affect the dollar value of our net
investment in foreign subsidiaries, with these fluctuations being included in a separate  component of
stockholders’ equity. At September 30, 2015,  we reported a cumulative foreign currency translation
adjustment of $36.1 million in stockholders’ equity as a  result of foreign  currency translation
adjustments, and we may incur additional adjustments in  future periods. In addition, operating results
of foreign subsidiaries are translated  into U.S. dollars for purposes  of our statements of comprehensive
income at average monthly exchange rates. Moreover, to the extent that our net sales are not
denominated in the same currency as our expenses, our net earnings could be materially adversely
affected. For example, a portion of labor, material and overhead costs for our facilities in the United
Kingdom, Germany, France and Italy are incurred in British Pounds or Euros, but in certain cases the
related net sales are denominated in U.S. dollars.  Changes in the value of the U.S. dollar or  other
currencies could result in material fluctuations in foreign currency translation amounts or the  U.S.
dollar value of transactions and, as a result, our net earnings could be materially  adversely affected. At
times we engage in hedging transactions to manage or reduce our foreign currency exchange risk, but
these transactions may not be successful and, as a result, our business,  financial  condition and results of
operations could be materially adversely affected. During fiscal 2015  and  2014, fluctuations in foreign
currency exchange rates had a negative  impact on net sales of $25.4 million and a positive impact on
net sales of $29.6 million, respectively.

Our international operations also cause our business  to  be  subject to the U.S. Export Control
regime and similar regulations in other countries, in particular in the United Kingdom. In  the United
States, items of a commercial nature are generally  subject to regulatory control by the U.S. Department
of Commerce’s Bureau of Industry and Security and its  Export  Administration Regulations, and the

18

19

International Traffic in Arms Regulations and other international trade regulations  may apply as well.
Additionally, we are not permitted to export some of the products we sell. In the future, regulatory
authorities may require us to obtain export licenses or  other export authorizations to export  the
products we sell abroad, depending upon  the nature of items  being exported, as  well as the  country  to
which  the export is to be made. We cannot assure  you that any of our  applications  for export licenses
or other  authorizations will be granted or  approved. Furthermore,  the  export license and export
authorization process is often time-consuming. Violation  of export control regulations could subject us
to fines and other penalties, such as losing the ability to export for a period of years, which  would limit
our  sales and significantly hinder our  attempts to expand our business  internationally.

Our total assets include substantial intangible  assets, and  the write-off of  a significant portion of our
intangible assets would negatively affect  our  financial results.

Our total assets reflect substantial intangible assets.  At September 30, 2015,  goodwill and

intangible assets, net represented 40% of our total assets. Goodwill  represents the excess of the
purchase price of acquired businesses  over the fair  value of the assets acquired and liabilities assumed
resulting from acquisitions, including  the acquisition of our  Company by affiliates of The Carlyle Group
(Carlyle) and the acquisition of Haas. Intangible  assets represent trademarks, backlogs, non-compete
agreements, technology and customer  relationships.  On at least an annual basis,  we assess  whether
there has been impairment in the value of goodwill and indefinite-lived  intangible  assets. If  our testing
identifies impairment under generally  accepted accounting principles in the  United States (GAAP), the
impairment charge we calculate would result in  a charge to income  from operations. For example,
during the three months ended September 30, 2015,  we recorded a non-cash  goodwill impairment  of
$263.8 million. Any determination requiring  the write-off  of  a significant portion of goodwill and
unamortized identified intangible assets  would negatively  affect our  results of operations and total
capitalization, which could be material.

Our international operations require us to comply with  numerous applicable anti-corruption and trade control
laws and regulations, including those of the U.S. government and various other jurisdictions, and our  failure
to comply with these laws and regulations  could adversely affect our  reputation, business, financial condition
and results of operations.

Doing business on  a worldwide basis  requires us  and our subsidiaries to comply with the laws and

regulations of the U.S. government and various other jurisdictions, and  our  failure to successfully
comply  with these rules and regulations may expose us to liabilities. These laws and regulations  apply
to companies, individual directors, officers,  employees and  agents, and may restrict our operations,
trade practices, investment decisions and partnering activities.

In particular, our international operations are subject  to  U.S. and foreign  anti-corruption  laws  and

regulations, such as the FCPA, the Bribery Act  and other applicable anti-corruption  regimes. These
laws generally prohibit us from corruptly providing anything  of  value, directly or indirectly, to
government officials for the purposes  of  improperly influencing  official decisions, improperly obtaining
or retaining business, or otherwise obtaining favorable treatment. As part  of  our  business,  we may deal
with governments and state-owned business enterprises, the employees and  representatives of which
may be considered government officials for purposes of the FCPA, the Bribery Act or other  applicable
anti-corruption laws. Some anti-corruption laws, such as the Bribery Act,  also prohibit commercial
bribery and the acceptance of bribes,  and  the FCPA further requires publicly traded  companies to
maintain adequate record-keeping and  internal accounting practices to accurately reflect the
transactions of the company. In addition,  some of  the international locations in which  we operate lack
a developed legal system and have elevated levels  of  corruption, and our  industry  is highly regulated,
which  increases our risk of violating anti-corruption laws.

As an exporter, we must comply with various laws and regulations relating to the export of
products, services and technology from the United States and other countries having jurisdiction over
our operations. In  the U.S., these laws include, among  others, the EAR administered by the U.S.
Department of Commerce, Bureau of  Industry and Security,  the ITAR administered by the U.S.
Department of State, Directorate of Defense Trade Controls (DDTC),  and trade sanctions, regulations
and embargoes administered by the U.S. Department of the Treasury, Office of Foreign Assets Control.
These laws and regulations may require us to obtain  individual validated licenses from the relevant
agency to export, re-export, or transfer commodities, software, technology, or services to certain
jurisdictions.

Violations of these legal requirements are punishable by  criminal fines and  imprisonment, civil

penalties, disgorgement of profits, injunctions,  debarment from government contracts, seizure and
forfeiture of unlawful attempted exports, and/or denial of export privileges, as well  as other remedial
measures. We have established policies and procedures designed to assist us, our personnel and our
agents to comply with applicable U.S. and international  laws and  regulations. However, there can be no
assurance that our policies and procedures  will  effectively prevent us,  our employees and our agents
from violating these regulations in every transaction in which we may engage, and violations, allegations
or investigations of such violations could materially  adversely affect our reputation, business, financial
condition and results of operations.

If any of our customers were to become insolvent  or experience substantial financial difficulties, our business,
financial condition and results of operations may be  adversely affected.

If any of the customers with whom we do business becomes insolvent or experiences substantial
financial difficulties we may be unable to timely  collect amounts owed to  us by such  customers and may
not be able to sell the inventory we have purchased for such customers, which could have a material
adverse effect on our business, financial condition  and results of operations.

Our suppliers or our customers may experience damage  to or disruptions at our or their facilities caused by
natural disasters and other factors, which may result in our business, financial condition and results of
operations being adversely affected.

Several of our facilities or those of our suppliers and customers  could be subject to a catastrophic

loss caused by earthquakes, tornadoes, floods, hurricanes, fire, power loss, telecommunication and
information systems failure or other similar events. Should insurance be insufficient to recover  all such
losses or should we be unable to reestablish our operations, or  if our customers or suppliers were to
experience material disruptions in their operations as  a result  of such events,  our business, financial
condition and results of operations could be adversely affected.

We are dependent on access to and the performance of third-party package delivery companies.

Our ability to provide efficient distribution of the products we sell to our customers is an integral

component of our overall business strategy. We  do not maintain our  own delivery networks, and instead
rely on third-party package delivery companies. We  cannot assure you that we  will always be able  to
ensure access to preferred delivery companies or  that these companies  will continue to meet  our needs
or provide reasonable pricing terms.  In addition, if  the package delivery companies on which we rely
experience delays resulting from inclement weather or other  disruptions, we may  be unable to maintain
products in inventory and deliver products to our customers on  a  timely basis, which may adversely
affect our business, financial condition and results of operations.

A significant labor dispute involving us  or one or more of our  customers  or suppliers,  or a  labor dispute that
otherwise affects our operations, could reduce  our net  sales and harm our profitability.

Labor disputes involving us or one or more of our  customers or suppliers  could  affect our
operations. If our customers or suppliers  are  unable to negotiate new labor agreements and  our
customers’ or suppliers’ plants experience slowdowns or closures as  a  result, our net sales and
profitability could be negatively impacted.

While our employees are not currently  unionized, they may attempt to form unions in the future,

and the employees of our customers,  suppliers and other service providers may  be,  or may in the  future
be, unionized. We cannot assure you that there will not be any strike, lock out or material labor dispute
with respect to our business or those of our  customers or suppliers  in the future that materially affects
our  business, financial condition and results of operations.

We may  be materially adversely affected  by  high fuel  prices.

Fluctuations in the global supply of crude oil  and  the possibility of changes in government policies

on the production, transportation and  marketing of jet fuel  make it impossible to predict  the future
availability and price of jet fuel. In the  event there  is an outbreak  or escalation of hostilities or other
conflicts or significant disruptions in  oil production or  delivery  in oil-producing areas or elsewhere,
there could be reductions in the production or  importation of crude oil and significant increases  in the
cost of jet fuel. If there were major reductions  in the availability of jet fuel or significant increases in  its
cost, commercial airlines would face increased operating costs. Due to the competitive nature  of the
airline industry, airlines are often unable to pass  on increases  in fuel prices  to  customers by increasing
fares. As a result, an increase in jet fuel could result in a  decrease  in net  income  from either lower
margins or, if airlines increase ticket  fares, lower net sales  from reduced airline travel. Decreases  in
airline profitability could decrease the  demand for new  commercial aircraft, resulting in  delays of  or
reductions in deliveries of commercial aircraft  that utilize the  products we sell,  and, as  a result, our
business, financial condition and results  of operations could be materially  adversely affected.

We have  identified material weaknesses  in  our internal  control over financial  reporting, which could result  in
a material misstatement to our annual or  interim consolidated financial  statements that  would not be
prevented or detected.

In connection with the audit of our consolidated financial statements as of  and for the year ended

September 30, 2015, we have concluded  that there are three material weaknesses relating to our
internal control over financial reporting. The existing material weakness that we  initially  identified as of
September 30, 2014 relates to a lack  of  a  sufficient complement of accounting  and financial reporting
personnel with an appropriate level of accounting knowledge and experience  commensurate with our
financial reporting requirements as of September  30, 2015. We  have concluded this material weakness
was a direct result of the heightened level of  activity associated with the integration of  the Haas
acquisition, combined with increased attrition attributable to  the  integration as  well as openings at
senior financial and organizational positions  for part of the  fiscal  year. This  material  weakness
contributed to the following two material weaknesses: (i) we did not maintain effective controls over
the preparation and review of account  reconciliation;  specifically,  our controls over the reconciliation of
our  balance sheet accounts did not operate effectively, and (ii) we did not maintain effective  controls
over the integration of policies, practices  and controls over  the Haas business unit.

A material weakness is a deficiency,  or a combination of  deficiencies, in  internal control over
financial reporting, such that there is  a reasonable possibility that a  material  misstatement of our
annual or interim financial statements  will not be prevented or detected on a  timely basis. As a result
of these  material weaknesses, management has concluded that our internal control over  financial
reporting and disclosure controls and procedures were not effective as of September 30,  2015.

As described in ‘‘Part II—Item 9A—Controls and Procedures’’  we have begun, and are currently in
the process of, remediating the material weaknesses. However, the measures we have taken and expect
to take to improve our internal controls may not be sufficient to address these issues, and we may need
to take additional measures to ensure that our internal controls are effective or to ensure that the
identified material weaknesses will not result in a material  misstatement of our annual or interim
consolidated financial statements.

If we fail to establish and maintain adequate internal control  over financial reporting, including

any failure to implement remediation  measures  and  enhancements for internal controls,  or if we
experience difficulties in their implementation, our business, financial  condition  and operating results
could be harmed. Further, any material weakness or unsuccessful remediation could affect investor
confidence in the accuracy and completeness of our  financial statements. As a result, our ability to
obtain additional financing on favorable terms  or at  all could be materially and adversely affected,
which in turn could materially and adversely affect our business, our strategic alternatives, our financial
condition and the market value of our securities. In addition, perceptions of us among customers,
lenders, investors, securities analysts and  others could  also be adversely affected.

We can give no assurances that the measures we have taken to date,  or any future measures  we

may take, will remediate the material  weaknesses identified or that  any additional material weaknesses
will not arise in the future. In addition, even if we are successful in strengthening our controls and
procedures, those controls and procedures may not be adequate to prevent  or identify  irregularities or
ensure the fair and accurate presentation  of our financial statements included in our periodic reports
filed with the SEC.

Our financial results may fluctuate from  period-to-period, making quarter-to-quarter comparisons of our
business, financial condition and results of operations less reliable indicators  of our future performance.

There are many factors, such as the cyclical nature of the aerospace industry,  fluctuations in our ad

hoc sales, delays in major aircraft programs, downward pressure on sales prices and changes in the
volume of our customers’ orders that could cause our financial results to fluctuate  from period-to-period.
For example, during the year ended September 30, 2015, 26% of our net sales were derived from ad hoc
sales. The prices we charge for ad hoc sales are typically higher than the prices under our Contract sales.
However, ad hoc customers may not continue to purchase the same amount of products from us as they
have in the past, so we cannot assure you that in any given year we will be able to generate similar net
sales from our ad hoc customers as we did in the past. We are also actively working  to transition
customers from ad hoc purchases to Contracts, which may also result in a reduction in ad hoc purchases.
In addition, our acquisition of Haas has contributed to lower our ad hoc sales as a percentage of net
sales. A significant diminution in our ad hoc sales in any given period could result in fluctuations in our
financial results and operating margins. As a result of these factors, we believe that quarter-to-quarter
comparisons of our financial results are not necessarily meaningful and that  these comparisons cannot be
relied upon as indicators of future performance.

We will continue to incur a significant increase  in costs as a result of operating as a publicly traded company,
and our management will be required to devote substantial time to  new compliance requirements and investor
needs.

As a publicly traded company, we will continue to incur  significant legal, accounting and other

expenses. In addition, the Sarbanes-Oxley Act of 2002 (the Sarbanes-Oxley  Act) and the rules of the
Securities and Exchange Commission (the SEC) and the New York Stock Exchange have imposed
various requirements on public companies.  Our  management and other personnel will continue to
devote a substantial amount of time to  these compliance initiatives.  Moreover, these rules and
regulations will continue to result in increased legal and financial compliance costs and make some
activities more time-consuming and costly. For example, we believe these rules and regulations make it

22

23

more difficult and more expensive for  us  to maintain appropriate levels of director and officer liability
insurance.

We are subject to health, safety and environmental  laws and regulations, any violation of which could subject
us to significant liabilities and penalties.

We  are subject to extensive federal, state, local and foreign laws,  regulations, rules and ordinances

relating to pollution, protection of the  environment and human  health and  safety, and  the handling,
transportation, storage, treatment, disposal and remediation of hazardous substances, including
potentially with respect to historical chemical blending and other  activities that pre-dated the  purchase
of the Haas business by us. Actual or  alleged  violations of EHS laws,  or permit requirements  could
result in restrictions or prohibitions on  operations and  substantial civil  or criminal  sanctions, as well as,
under some EHS laws, the assessment of strict liability and/or joint and several liability.

Furthermore, we may be liable for the costs  of  investigating and  cleaning up environmental
contamination on or from our operations or  at off-site locations,  including potentially  with respect  to
historical chemical blending and other  activities that pre-dated the purchase of the Haas business by us.
We  may therefore incur additional costs and expenditures beyond  those currently anticipated  to  address
all such known and unknown situations  under  existing and future EHS laws.

Governmental, regulatory and societal demands  for  increasing  levels of product safety and

environmental protection could result in  increased  pressure for  more stringent regulatory  control with
respect to the chemical industry. For example, the Hazard Communication Standard  promulgated  by
the U.S.  Occupational Safety and Health Administration  is now aligned with the Globally Harmonized
System of Classification and Labeling  of  Chemicals, which requires our suppliers to make revisions  to
labels and safety data sheets. Changes in  the regulatory environment, particularly, but not limited to, in
the United States, the European Union, Canada  and China, could lead to heightened regulatory
scrutiny and could adversely impact our  ability  to  supply certain products to and  provide supply chain
management services to our customers. For instance, the August  2015 explosion at  the port of Tianjin,
China, may lead to stricter chemical safety standards  in that country. The  European Union’s
Registration, Authorization and Restriction of Chemicals and analogous non-European Union  laws  and
regulations, or other similar laws and  regulations,  also could result  in compliance  obligations, fines,
ongoing monitoring and other future business  activity restrictions,  which could have  a material adverse
effect on our business, financial condition  and  results of operations.

In addition, these concerns could influence public perceptions regarding our operations and our

ability to attract and retain customers and employees.  Moreover, changes in EHS  regulations could
inhibit or interrupt our operations, or  require  us to modify our facilities or operations. Accordingly,
environmental or regulatory matters  may cause us to incur significant unanticipated losses,  costs, capital
expenditures or liabilities, which could  reduce  our profitability. Such losses, costs, capital expenditures
or liabilities will be subject to evolving regulatory requirements  and will  depend on the timing  of  the
promulgation and enforcement of specific  standards which impose requirements on  our  operations. As
a result, these losses, costs, capital expenditures or liabilities may be more than currently anticipated.

Our operations involve risks associated with  the handling, transportation, storage and  disposal of chemical
products  that may increase our operating costs and  reduce our profitability.

Our business is subject to hazards inherent  in the handling, transportation, storage and  disposal of
chemical products. These hazards include:  chemical  spills, storage tank  leaks, discharges  or releases of
toxic or hazardous substances or gases  and other hazards incident  to  the handling, transportation,
storage and disposal of dangerous chemicals. We are  also potentially  subject to other hazards, including
natural disasters and severe weather; explosions and fires;  transportation  problems, including
interruptions, spills and leaks; mechanical  failures; unscheduled downtimes; labor difficulties; and other

risks. Many potential hazards can cause bodily injury and loss of life, severe  damage to or destruction
of property and equipment and environmental  damage, and  may result in suspension of  our own or our
customers’ operations and the imposition  of civil or criminal penalties and liabilities. Furthermore, we
are subject to present and future claims with respect to our employees when working within our own
operations or when supplying chemicals to and/or providing chemical management  services at our
customer’s operations, other persons, including potentially our customers and their employees, workers’
compensation and other matters.

We maintain property, business interruption,  products liability and casualty insurance policies
which we believe are in accordance with customary industry practices,  as well as insurance policies
covering other types of risks, including pollution legal  liability insurance, but  we are not fully insured
against all potential hazards and risks incident to our business. Each of these insurance policies is
subject to customary exclusions, deductibles and coverage limits,  in accordance with industry standards
and practices. As a result of market conditions, premiums and deductibles for certain insurance  policies
can increase substantially and, in some  instances, certain  insurance may become unavailable  or available
only for reduced amounts of coverage. If we were to incur a significant liability for which we were  not
fully insured, it could have a material adverse effect on our business, results of operations, financial
condition and liquidity.

If the temperature control systems on which we rely fail,  certain of  the chemical products we sell may become
‘‘non-conforming’’ while in storage or in transit, and as a result, we may be responsible for providing
replacement products to our customers, which could have a material adverse  effect on our business, financial
condition and results of operations.

Many of the chemical products we sell are sensitive to temperature. Our storage facilities and the

vehicles maintained by the third-party delivery companies on whom we rely  utilize sophisticated
temperature control systems to ensure safe storage and handling  of  these  products. If these
temperature control systems fail, products that are sensitive to temperature may  become
non-conforming to the customer’s specifications, and we  may be responsible  for providing replacement
products, which could have a material  adverse effect on  our business, financial condition and results of
operations.

Our reputation and/or our business, financial condition and results of operations could be adversely affected if
one of the products we sell causes an aircraft to crash.

We may be exposed to liabilities for personal injury, death or property damage as a  result of the

failure of a product we have sold. We typically agree to indemnify  our customers against certain
liabilities resulting from the products we sell, and any third party  indemnification we seek from our
suppliers and our liability insurance may not fully cover  our indemnification obligations to customers.
We also may not be able to maintain  insurance coverage  in the future at an acceptable cost. Any
liability for which third-party indemnification is not available  that is not covered  by  insurance could
have a material adverse effect on our business, financial condition and results of operations.

In addition, a crash caused by one of the products  we have sold could damage our reputation  for

selling quality products. We believe our customers consider safety and  reliability as key criteria in
selecting a provider of aircraft products and believe our reputation for quality  assurance is a significant
competitive strength. If a crash were to be caused by  one  of  the products we sold,  or if we were to
otherwise fail to maintain a satisfactory record of safety and reliability, our ability to retain and attract
customers may be materially adversely affected.

We sell products to a highly regulated industry and our business may be adversely affected  if our suppliers or
customers lose government approvals, if more stringent  government  regulations are enacted or if industry
oversight is increased.

The aerospace industry is highly regulated  in the United  States and in other countries. The  FAA

prescribes standards and other requirements for aircraft components in  the U.S.  and comparable
agencies, such as the European Aviation  Safety Agency, the Civil Aviation  Administration of China and
the Japanese Civil Aviation Bureau, regulate these matters  in other countries. Our suppliers  and
customers must generally be certified  by  the FAA, the DoD and similar agencies in foreign countries. If
any of our suppliers’ government certifications are revoked,  we  would be less likely  to  buy such
supplier’s products, and, as a result,  would need  to  locate a suitable  alternate supply of such products,
which  we may be unable to accomplish  on commercially reasonable terms  or at all. If any  of  our
customers’ government certifications  are  revoked,  their  demand for the products  we sell would decline.
In each case, our business, financial condition and results of operations may  be  adversely affected.

In addition, if new and more stringent  government regulations are adopted or  if industry  oversight

increases, our suppliers and customers  may incur significant  expenses to comply  with such  new
regulations or heightened industry oversight. In the case  of  our suppliers, these  expenses may  be  passed
on to us in the form of price increases, which we may be unable to pass  along to our  customers.  In the
case of our customers, these expenses may  limit  their  ability to purchase  products from  us. In  each
case, our business, financial condition  and  results of  operations  may  be  adversely affected.

We may  be unable to successfully consummate or integrate future acquisitions, which could negatively impact
our business, financial condition and results  of operations.

We  may consider future acquisitions, some of which could be material to us. Depending upon the
acquisition opportunities available, we  may need  to  raise additional funds through the  capital markets
or arrange for additional debt financing  in order to consummate such acquisitions. We may  be  unable
to raise the capital required for future acquisitions on satisfactory terms  or at  all,  which could adversely
affect our business, financial condition and results  of operations.

Our substantial indebtedness could adversely  affect  our financial health  and could harm our ability to react to
changes to our business.

As of September 30, 2015, our total long-term indebtedness outstanding under our Credit Facilities

(as defined in Part II, Item 7, ‘‘Management’s Discussion  and  Analysis of Financial Condition and
Results of Operations—Liquidity and Capital Resources—Credit Facilities—Senior  Secured  Credit
Facilities’’) was $952.9 million, which was 53.8% of our  total capitalization.

In addition, we may incur substantial  additional  indebtedness in  the future.  Our Credit Facilities

contain a number  of significant qualifications and exceptions that allow  us to incur additional
indebtedness, and the indebtedness incurred in compliance with these  qualifications and exceptions
could be substantial. If we incur additional debt, the risks associated  with our substantial  leverage
would increase.

Our substantial indebtedness could have important  consequences to investors. For example, it

could:

• increase our vulnerability to general economic  downturns and industry conditions;

• require us to dedicate a substantial portion of our  cash flow from operations to payments on  our
indebtedness, thereby reducing the availability of our cash  flow  to  fund working capital,  capital
expenditures and other general corporate requirements;

• limit our flexibility in planning for, or reacting to, changes in our business and the industry in

which we operate;

• place us at a competitive disadvantage compared to competitors that have less debt; and

• limit, along with the financial and other restrictive covenants contained in the documents

governing our indebtedness, among other things, our ability to borrow  additional funds,  make
investments and incur liens.

In addition, all of our debt under the Credit Facilities bears interest at  floating rates, causing us to

enter into interest rate swap derivative instruments to partially offset our exposure to interest rate
fluctuations, which result in additional risks. As  of September 30, 2015, we had a  current interest rate
hedge liability and a long-term interest rate hedge liability of $1.9 million and $2.2 million, respectively.
If our interest rate hedge was determined ineffective partially or entirely as defined by GAAP, the
ineffective portion or the entire amount  of  our interest rate hedge liabilities would adversely affect our
earnings. Our derivatives also expose us to credit risk to the extent that  the counterparties may be
unable to meet the terms of the agreement, which could  negate the  intended protection from our
hedge instruments. See further discussion on our derivative  financial instruments in Note 12 of the
Notes to Consolidated Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K.

Our level of indebtedness increases the possibility that  we may  be  unable to generate cash
sufficient to pay, when due, the principal of, interest on or other amounts due in respect of our
indebtedness. We cannot assure you that  our business will generate sufficient  cash flow from operations
or that future borrowings will be available to us under the Credit Facilities or otherwise in amounts
sufficient to enable us to service our indebtedness. If we cannot  service our  debt, we will have to take
actions such as reducing or delaying capital investments,  selling assets, restructuring or refinancing our
debt or seeking additional equity capital and cannot assure you that we will be successful in
implementing any such actions or that any actions we  take  will allow us to stay in compliance with the
terms of our indebtedness.

The terms of the Credit Facilities and other debt instruments may restrict our current  and future operations,
particularly our ability to respond to changes or to take certain actions.

The Credit Facilities contain a number of restrictive covenants that impose significant operating
and financial restrictions on us and may limit our ability to engage in acts that may be in  our long-term
best interests. The Credit Facilities include covenants restricting, among other things, our ability to:

• incur or guarantee additional indebtedness or issue preferred stock;

• pay distributions on, redeem or repurchase our capital stock or redeem or repurchase our

subordinated debt;

• make investments;

• sell assets;

• enter into agreements that restrict distributions or other payments from our restricted

subsidiaries to us;

• incur or allow existing liens;

• consolidate, merge or transfer all or substantially  all of our assets;

• engage in transactions with affiliates;

• enter into sale leaseback transactions;

• change fiscal periods;

26

27

• enter into agreements that restrict  the granting  of liens  or the making of subsidiary distributions;

• create unrestricted subsidiaries; and

• engage in certain business activities.

In addition, the Credit Facilities contain financial maintenance covenants,  including a  maximum

leverage  ratio covenant and a minimum interest coverage ratio covenant. A  breach of  any of these
covenants could result in a default under  the Credit  Facilities. If any such  default occurs, the lenders
under the Credit Facilities may elect  to declare  all  outstanding borrowings, together with accrued
interest and other  amounts payable thereunder, to be immediately  due and payable. The lenders under
the Credit Facilities also have the right  in  these circumstances to terminate any commitments they  have
to provide further borrowings. In addition,  following  an event of default under the Credit Facilities,  the
lenders under those facilities will have the right to proceed against the collateral granted to them to
secure the debt, which includes our available  cash.  If the debt under the Credit Facilities was  to  be
accelerated, we cannot assure you that  our assets would be sufficient  to  repay in full  our  debt. See
Part II, Item 7. ‘‘Management’s Discussion  and  Analysis of Financial Condition  and Results of
Operations—Liquidity and Capital Resources—Credit Facilities—Senior Secured Credit Facilities’’ for
additional information about the Company’s  compliance with the financial maintenance  covenants
contained in the Credit Facilities, in particular  the Consolidated Total  Leverage Ratio (as such ratio is
defined in the Credit Facilities).

Risks Related to our Common Stock

The price of our common stock may fluctuate significantly, and you could lose all  or part  of  your  investment.

Volatility in the market price of our  common  stock may prevent you from being able to sell your

common stock at or above the price you paid for your  common  stock. The market price of our
common stock could fluctuate significantly for  various reasons,  including:

• our operating and financial performance  and  prospects;

• our quarterly or annual earnings or those  of  other companies in  our industry;

• the public’s reaction to our press releases, our other public announcements  and our filings with

the SEC;

• changes in, or failure to meet, earnings estimates or recommendations  by  research  analysts  who

track our common stock or the stock of other companies in our  industry;

• the failure of analysts to cover our common  stock;

• credit ratings downgrades or other negative actions by  ratings agencies for  us  or our subsidiaries;

• strategic actions by us or our competitors, such as acquisitions or  restructurings;

• new laws or regulations or new interpretations of existing  laws or regulations  applicable  to  our

business;

• changes in accounting standards, policies, guidance, interpretations or principles;

• the impact on our profitability temporarily caused by the time lag between when we  experience

cost increases until these increases flow through  cost of sales because of  our  method of
accounting for inventory, or the impact  from our inability to pass on  such price  increases to our
customers;

• material litigation or government investigations;

• changes in general conditions in the United  States and global economies or financial markets,

including those resulting from war, incidents of terrorism or responses to such events;

• changes in key personnel;

• sales of common stock by us or members of our  management team;

• the granting or exercise of employee stock options or other equity awards;

• the volume of trading in our common stock;  and

• the realization of any risks described under  ‘‘Risk Factors.’’

In addition, in recent years, the U.S. stock  market has experienced significant price and volume

fluctuations. This volatility has had a significant impact on  the market price of securities issued by
many companies, including companies in our  industry. The changes have  often  been unrelated or
disproportionate to the operating performance  of  the affected  companies. Hence, the price of our
common stock could fluctuate based upon factors that have little or nothing to do with our Company,
and these fluctuations could materially reduce our share price and cause you to lose all or part of your
investment. Further, in the past, market fluctuations  and  price declines in a company’s stock have led
to securities class action litigations. If such  a suit were to arise, it could have a substantial cost and
divert our resources regardless of the outcome.

If securities analysts do not publish research or reports about our business or if they downgrade our stock, the
price of our stock could decline.

The research and reports that industry or financial analysts  publish about us or our business may
vary widely and may not predict accurate results, but will likely have an effect on  the trading price of
our common stock. If an industry analyst decides not to cover our Company,  or if an industry analyst
decides to cease covering our Company at some point in the future, we could lose visibility in the
market, which in turn could cause our stock price to decline. If an industry analyst downgrades our
stock, our stock price would likely decline rapidly in response.

We have no plans to pay regular dividends on our common stock, so you may not receive funds without selling
your common stock.

We have no plans to pay regular dividends on our common stock. We generally intend to invest

our future earnings, if any, to fund our growth. Any payment  of  future dividends will be at the
discretion of our Board of Directors and will depend on, among other things,  our earnings, financial
condition, capital requirements, level of indebtedness, statutory  and contractual restrictions applying to
the payment of dividends and other considerations that our Board of Directors deems relevant. The
Credit Facilities also effectively limit our ability to pay dividends. Accordingly, you may have  to  sell
some or all of your common stock in order to generate cash flow  from your investment.  You may not
receive a gain on your investment when you sell your  common stock and you may lose the entire
amount of the investment.

Provisions of our amended and restated certificate of incorporation and amended and restated bylaws and
Delaware law might discourage, delay or  prevent a change of control  of our company or changes in our
management and, as a result, depress the  trading price of our common stock.

Our amended and restated certificate of incorporation  and amended and restated bylaws contain
provisions that could discourage, delay or prevent a change in control of our Company or changes in
our management that the stockholders of our Company may deem advantageous. These provisions:

• establish a classified Board of Directors,  with three  classes of directors;

28

29

• authorize the issuance of blank check preferred stock that  our Board  of Directors  could  issue  to

increase the number of outstanding shares  and to discourage a takeover  attempt;

Our CSLs are supported by sales offices throughout the  U.S., Canada, China, France,  Germany, India,
Israel, Italy, Singapore and the United Kingdom.

Complementing our CSLs and sales offices are FSLs. An FSL is a  specialized  stocking point for
one or more Contracts located within a geographic region. FSLs are typically located either near or
within a customer facility and are established to support large  Contracts.  In certain instances, FSLs
initially established to service a single customer  are expanded to service other regional customers.

We believe that our existing facilities, including both owned  and leased, are in good condition and

suitable for the conduct of our business. For additional information regarding obligations under
operating leases, see Note 17 of the  Notes to Consolidated Financial Statements in Part II, Item 8 of
this Annual Report on Form 10-K.

ITEM 3. LEGAL PROCEEDINGS

We are involved in various legal matters that arise in the  ordinary  course of our business. We

believe that the ultimate outcome of such matters  will  not have a material adverse effect on our
business, financial condition or results of operations. However, there can be no assurance that such
actions will not be material or adversely  affect our business, financial  condition  or results of operations.
For more information see Note 17 of the Notes to Consolidated  Financial Statements in Part II, Item 8
of this Annual Report on Form 10-K.

ITEM 4. MINE SAFETY DISCLOSURES

Not applicable.

• limit the ability of stockholders to remove  directors;

• prohibit our stockholders from calling  a special  meeting of stockholders;

• prohibit stockholder action by written consent, which requires all stockholder actions  to  be  taken

at a meeting of our stockholders;

• provide that our Board of Directors is  expressly  authorized  to  adopt,  or  to  alter or  repeal our

bylaws; and

• establish advance notice requirements for  nominations for election  to  our Board of Directors  or

for proposing matters that can be acted upon by stockholders at stockholder meetings.

These anti-takeover defenses could discourage,  delay or prevent a transaction  involving a change in

control of our Company. These provisions  could also discourage  proxy  contests and make it more
difficult for you and other stockholders to elect directors of your  choosing and cause  us to take
corporate actions other than those you  desire.

Future sales of our common stock in the public market  could lower our  share price,  and any additional
capital raised by us through the sale of equity or  convertible debt securities may dilute your  ownership in  us
and may  adversely affect the market price of our common stock.

We  and our existing stockholders may sell additional  shares  of  common  stock in subsequent  public
offerings. We may also issue additional  shares of  common  stock or convertible  debt  securities to finance
future acquisitions. As of September  30, 2015, we had 950,000,000 shares of common stock authorized
and 97,538,124 shares of common stock  outstanding.  In addition, we have 3,242,018 shares of  common
stock issuable upon the exercise of options  outstanding as of September 30, 2015  and 5,514,078
available shares of common stock reserved for issuance under  the Wesco Aircraft Holdings,  Inc. 2014
Incentive Award Plan (the 2014 Plan).

We  cannot predict the size of future issuances  of  our common stock or the  effect,  if  any, that
future issuances and sales of our common stock will have on the  market  price of our common stock.
Sales of substantial amounts of our common stock (including sales pursuant to Carlyle’s registration
rights and shares issued in connection with an acquisition), or the perception that such  sales could
occur, may adversely affect prevailing market prices for our common stock.

ITEM 1B. UNRESOLVED STAFF COMMENTS

None.

ITEM 2. PROPERTIES

Our global headquarters is located at 24911 Avenue Stanford, Valencia, California 91355. As of
September 30, 2015, we have a total  of 88  administrative, sales and/or stocking facilities, all of which
are either leased or located at a customer site, except for our global  headquarters,  which is  owned by
us. These facilities, including one in Wichita, Kansas, one in Toronto,  Ontario and one in Clayton West,
United Kingdom, are located in 20 countries,  including the  U.S.,  Canada,  China, France,  Germany,
India, Israel, Italy, Singapore and the United  Kingdom.

Our warehouse operations are divided between CSLs  and  Forward Stocking Locations (FSLs). Our

CSLs serve as the primary supply warehouses for most  of our net sales  and  also house our
procurement, customer service, document  control, IT,  material  support and quality assurance functions.

Stockholders

On September 30, 2015, the closing price reported on the New  York Stock Exchange of our
common stock was $12.20 per share.  As  of November  23, 2015, we had  approximately103  holders of
record of our common stock.

Dividends

We  have not paid dividends in the past  and we do not intend to pay any cash  dividends  for the
foreseeable future. We intend to retain earnings, if any, for the future operation and  expansion of our
business and the repayment of debt. Any  determination to pay  dividends in  the future will be at the
discretion of our Board of Directors and will depend  upon our  results of  operations, cash  requirements,
financial condition, contractual restrictions,  restrictions  imposed by applicable laws and  other  factors
that our Board of Directors may deem  relevant. Our existing  indebtedness effectively  limits our  ability
to pay dividends and make distributions to our stockholders.

Recent  Sales of Unregistered Securities

None.

The graph set forth below compares the cumulative total shareholder return on our common stock
between July 28, 2011 (our first trading day on  the New  York Stock Exchange) and September 30, 2015
to (1) the cumulative total return of U.S. companies listed on the New  York Stock Exchange and
(2) the cumulative total return of a peer  group selected by the Company (BE Aerospace, Inc. (BEAV),
Esterline Technologies Corporatoin (ESL),  Fastenal Company (FAST), HEICO Corporation (HEI),
KLX Inc. (KLXI), MSC Industrial Direct Co., Inc. (MSM), Transdigm Group Incorporated (TDG)  and
W.W. Grainger, Inc. (GWW)) over the same period. The peer group reflects a mix  of companies that
we believe is reflective of our broader  industry and line-of-business. This graph assumes an initial
investment of $100 on July 28, 2011, in our common stock, the market  index and the peer group and
assumes the reinvestment of dividends, if  any. The graph also assumes that the price of our common
stock on July 28, 2011 was equal to the closing price of $14.92. The historical  information set forth
below is not necessarily indicative of  future price performance.

ITEM 7. MANAGEMENT’S DISCUSSION AND ANALYSIS OF  FINANCIAL  CONDITION AND

RESULTS OF OPERATIONS

The following discussion and analysis is intended to help the reader understand our business, financial

condition, results of operations, liquidity and capital resources. You should read this discussion in
conjunction with our consolidated financial statements and the related notes contained elsewhere in this
Annual Report on Form 10-K.

The statements in this discussion regarding industry trends, our expectations regarding our future
performance, liquidity and capital resources and other  non-historical statements  are  forward-looking
statements. These forward-looking statements are subject to numerous risks and uncertainties, including, but
not limited to, the risks and uncertainties described in Part I, Item 1A. ‘‘Risk Factors’’ and  ‘‘Cautionary
Note Regarding Forward- Looking Statements.’’ Our actual results  may  differ  materially from  those
contained in or implied by any forward-looking statements.

Industry Trends Affecting Our Business

We rely on demand for new commercial and military aircraft for a significant portion of our  sales.

Commercial aircraft demand is driven by many factors, including the global economy, passenger
volumes, airline profitability, introduction of new aircraft models, and the lifecycle of current fleets.
Demand for business jets is closely correlated to regional economic conditions  and corporate profits,
but also influenced by new models and changes in ownership dynamics. Military aircraft demand is
primarily  driven by government spending, the timing of orders  and evolving DoD strategies and
policies.

Aftermarket demand benefits from many of the  same trends as those in OEM channels, but is also

impacted by requirements to maintain aging aircraft and the cost of fuel, which can lead  to  greater
utilization of existing planes. Demand in the  military aftermarket  is further driven by changes in overall
fleet size and the level of U.S. military activity overseas.

Supply chain service providers and distributors have been aided by these trends along with  an

increase  in outsourcing activities, as OEMs and their suppliers focus on reducing costs.

Commercial Aerospace Market

Over the past three years, major airlines have ordered new aircraft at  a  robust pace, aided by
strong profits and increasing passenger volumes. At the same time, volatile fuel prices have led to
greater demand for fuel-efficient models and new engine options for  existing aircraft designs. As a
result, large commercial OEMs have reported increased deliveries and unprecedented backlog levels.
The rise of emerging markets has added to this growth at a stronger pace  than seen historically.
Business aviation has lagged the larger commercial market,  reflecting a deeper  downturn in  the
recession. Production levels remain well below their pre-recession peak, though this has been offset
somewhat by stronger demand for large, more expensive aircraft.

Military Aerospace Market

Military build-rates have declined recently (and may  continue to decline going forward), negatively

impacting this portion of our business. We believe the diversity of the military aircraft programs we
support can help mitigate the impact of program delays, changes or cancellations. Increased sales to
other active programs that directly benefit from such changes also help moderate build-rate declines. In
addition, we believe the services we provide the Joint Strike Fighter program will benefit our future
business as production increases.

Goodwill Impairment

Fluctuations in Margins

We  performed our Step 1 goodwill impairment tests on July 1,  2015. The results of these tests
indicated that the estimated fair values of  our reporting units exceeded their carrying values,  with the
exception of the North America Hardware reporting unit  within our North America segment. The
impact of market pressures such as decreasing  revenue and underperformance relative to forecast
adversely impacted the fair value of this reporting unit. Additionally, lower projected  revenue growth
and operating results reflected changes in assumptions related  to  organic growth  rates,  market trends,
business mix, cost structure and other  expectations about  the anticipated short-term and long-term
operating results of this reporting unit.  As a result, we proceeded to Step 2  of the goodwill impairment
analysis, and compared the implied value  of North America Hardware’s goodwill with the  carrying
value of its goodwill, and since the carrying value exceeded the implied fair  value, we recorded a
non-cash impairment charge of $263.8  million in the  three months ended September 30, 2015.

Other Factors Affecting Our Financial Results

Fluctuations in Revenue

There are many factors, such as fluctuations in ad hoc sales, timing of aircraft  deliveries, changes

in selling prices, the amount of new customers’ consigned inventory  and the volume or  timing of
customer orders that can cause fluctuations  in our financial results  from  quarter-to-quarter.  To
normalize for short-term fluctuations, we tend  to  look at our  performance over  several quarters or
years of activity rather than discrete short-term periods. As  such, it can  be  difficult to determine
longer-term trends in our business based  on quarterly comparisons.

We  will continue our strategy of seeking  to  expand our relationships with  existing customers by
transitioning them  to Contracts, as well as  expanding  relationships with our existing Contract customers
to include additional customer sites, additional SKUs and additional levels  of  service.  We believe this
strategy serves to mitigate fluctuations  in our net sales. However, our sales to Contract  customers may
fail to meet our expectations for a variety of reasons, in particular if  industry  build rates are lower than
expected or, for certain newer JIT customers, if their  consigned  inventory, which  must  be  exhausted
before corresponding products are purchased directly from us, is larger than we  expected.

During  the year ended September 30, 2014, we modified and extended a contract with an  existing
customer that resulted in a $66.3 million reduction in net sales  to  the customer during the year ended
September 30, 2015.

If any of our customers are acquired or controlled by a  company that elects not to utilize  our
services, or attempt to implement in-sourcing initiatives, it could have a negative effect on  our  strategy
to mitigate fluctuations in our net sales. Additionally, although  we  derive a  significant portion  of our
net sales from the building of new commercial and  military  aircraft, we have not typically experienced
extreme fluctuations in our net sales when sales for  an individual aircraft program decrease, which  we
believe is attributable to our diverse  base of customers  and programs.  In addition, we believe our
substantial sales under Contracts helps  to  mitigate fluctuations in our  financial results, as Contract
customers tend to have steadier purchasing patterns  than  ad hoc customers. However, as mentioned
above, our sales to Contract customers  may fail  to  meet our expectations  for a variety of reasons, in
particular if industry build rates are lower  than expected  or,  for certain newer JIT customers, if their
consigned inventory, which must be exhausted  before  corresponding  products are purchased directly
from us, is larger than we expected or if  estimated  usage rates are  actually  lower. In addition,  we
believe that during industry growth cycles,  our customer’s  demand may begin to exceed supplier lead
times, which could result in an increase  in  our ad  hoc sales.

We added chemicals to our product offerings  in connection  with our Haas acquisition on

February 28, 2014. Gross profit margins on chemicals  are lower than  the gross profit margins on many
of the products we sold prior to the Haas acquisition, which resulted in a  reduction in our overall gross
profit margins. In addition, we believe  our gross profit margins may also be negatively impacted to the
extent other lower-margin product lines,  such as  electronic components, exceed the growth rates of
higher margin product lines. In addition, there continues to be pricing pressure throughout the supply
chain.

We also believe that our strategy of growing our Contract sales and converting ad hoc customers
into Contract customers could negatively affect our gross profit margins, as  gross profit margins tend to
be higher on ad hoc sales than they are on Contract-related sales. However, we believe any potential
adverse impact on our gross profit margins is  outweighed  by the  benefits of a  more stable long-term
revenue stream attributable to Contract customers.

During the years ended September 30, 2014 and 2013, we saw  increased competition in the ad hoc

market, which has slightly reduced our typically higher ad hoc margins, which remained relatively
consistent through fiscal 2015. We expect the current margins to remain  relatively consistent throughout
fiscal 2016. However, we believe that as industry  build rates and manufacturer lead times increase,
margins on ad hoc sales will begin to increase.

Our Contracts generally provide for fixed  prices, which can expose  us to risks if prices we  pay to

our suppliers rise due to increased raw material or other costs. However,  we  believe our expansive
product offerings and inventories, our ad hoc sales and, where possible, our longer-term agreements
with suppliers have enabled us to mitigate this risk.

Fluctuations in Cash Flow

We believe our cash flows may be affected by  fluctuations in our inventory that can occur over

time. When we are awarded new programs, we have generally increased our inventory to account  for
expected sales related to the new program,  which often take time to materialize. As a  result, if certain
programs for which we have procured inventory are delayed  or if certain newer JIT customers’
consigned inventory is larger than we expected, we may experience a more sustained inventory increase.
For example, we increased our inventory in anticipation of deliveries of the Boeing 787, which
experienced significant delays.

Inventory fluctuations may also be attributable to general industry  trends. Factors that may
contribute to fluctuations in inventory levels in the future could include (1) strategic purchases (a) to
take advantage of favorable pricing, (b) made in anticipation of the expected industry  growth cycle,
(c) to support new customer Contracts or  (d) to acquire high-volume products  that are typically
difficult to obtain in sufficient quantities, (2) changes in supplier lead  times and the  timing of inventory
deliveries, (3) purchases made in anticipation of future growth  (particularly growth in our MRO
business) and (4) purchases made in connection with the expansion of existing Contracts. While
effective inventory management is an ongoing challenge, we continue to take steps to enhance  the
sophistication of our procurement practices to mitigate the negative impact of inventory buildups on
our cash flow.

Our accounts receivable balance as a percentage  of  net sales may fluctuate  from

quarter-to-quarter. These fluctuations are primarily driven  by changes,  from quarter-to-quarter, in the
timing of sales and the current average days’ sales outstanding. The  completion of  customer Contracts
with accelerated payment terms can also contribute to these  quarter-to-quarter  fluctuations. Similarly,
our accounts payable may fluctuate from quarter-to-quarter, which is primarily driven by the timing of
purchases or payments made to our suppliers.

Segment Presentation

We  conduct our business through two reportable segments: North America  and Rest of World. We
evaluate  segment performance based  on segment  income  or loss from operations.  Each segment  reports
its  results of operations and makes requests for capital expenditures and acquisition funding to our
chief operating decision maker (CODM). Our chief executive officer serves as our CODM.

Change in Estimate—Inventory Excess  and Obsolescence  (E&O) Reserve

In the three months ended September  30, 2015, management implemented a new  strategy of

providing integrated supply chain services  more tailored to customer demand through  long-term
contracts and focused forecasted consumption, including  changes  to  our inventory purchasing strategy,
holding inventory for shorter periods  and the  planned scrapping  of long dated inventory.  The  new
strategy and updates for fiscal 2015 sales  activities led to changes  in the sell through rates, holding
period of aged inventory and others estimates used in the E&O reserve  for our hardware inventory,
which  increased our E&O inventory reserves by  $43.8 million.

Revision of Statements of Comprehensive  Income

In the three months ended September  30, 2015, we determined that  certain  personnel costs
incurred pursuant to certain service contracts were  charged  to  selling,  general and administrative
expenses rather than to cost of sales.  We  have revised our statements of comprehensive income to
properly state such selling, general and administrative expenses as cost of sales. We misclassified
expenses of $15.4 million, and $4.7 million  for  the years ended September 30,  2014 and 2013,
respectively. The expenses misclassified for  North  America were  $14.0 million, and $3.6 million for the
years ended September 30, 2014 and 2013, respectively. The expenses  misclassified for Rest of World
were $1.4 million and $1.0 million for  the years ended September 30, 2014 and 2013, respectively.
These misclassifications had no effect on  previously reported income from operations, net income or
cash flows for the years ended September  30,  2014 and  2013 and  the interim  periods within those  years.
We  have evaluated these misclassifications and do not believe  they are material  to  any prior  periods.

Key Components of Our Results of Operations

The following is a discussion of the key  line items included  in our financial statements for the
periods presented below under the heading ‘‘Results  of Operations.’’ These are the measures that
management utilizes to assess our results of  operations, anticipate  future trends and  evaluate risks in
our  business.

Net Sales

Our net  sales include sales of hardware, chemicals, electronic components, bearings, tools and

machined parts, and eliminate all intercompany sales. We also provide certain services to our
customers, including quality assurance,  kitting, JIT  delivery and point-of-use  inventory management.
However, these services are provided  by  us  contemporaneously with the delivery of  the product, and as
such, once the product is delivered, we  do not  have a post-delivery obligation to provide services to the
customer. Accordingly, the price of such  services  is generally  included in the  price of the products
delivered to the customer, and revenue  is  recognized upon delivery of the product, at which  point, we
have satisfied our obligations to the customer. We  do  not account for these services as a  separate
element, as the services generally do  not have  stand-alone value and  cannot be separated from  the
product  element of the arrangement.

We  serve our customers under both Contracts, which include JIT contracts and LTAs,  and ad hoc

sales. Under JIT contracts, customers  typically commit to purchase specified products from us at a fixed
price, on an if-and-when needed basis, and we are responsible for maintaining high  levels of stock

availability of those products. LTAs are typically negotiated  price lists for customers or individual
customer sites that cover a range of pre-determined products, purchased on an as-needed basis. Ad hoc
customers purchase products from us  on an  as-needed basis and are generally supplied out of our
existing inventory. In addition, Contract customers often purchase products that are not captured under
their Contract on an ad hoc basis.

Income from Operations

Income from operations is the result of subtracting the cost of  sales and selling, general, and

administrative expenses from net sales, and is  used  primarily to evaluate our performance and
profitability.

The principal component of our cost of sales is product cost, which was 94.8% of our total cost of

sales for the year ended September 30, 2015. The remaining components are freight and  expediting
fees, import duties, tooling repair charges, packaging supplies and  physical inventory adjustment
charges, which collectively were 5.2% of our total cost of sales for the  year ended  September 30, 2015.

Product cost is determined by the current weighted average cost of each inventory item, except for
chemical parts for which the first-in,  first-out method is used, and the adjustment to the reserve, if any,
for excess and obsolete inventory. The inventory reserve is  calculated to estimate the amount of excess
and obsolete inventory we currently have on-hand. We review inventory for excess  quantities and
obsolescence quarterly and adjust the reserve and  future forecasted sell-through rates as necessary. For
a description of our E&O reserve policy, see ‘‘—Critical Accounting Policies and Estimates—
Inventories.’’ Charges to cost of sales for the increase  om our E&O reserve and related items of
$95.1 million, $17.7 million and $8.7 million were recorded during the years ended September 30, 2015,
2014 and 2013, respectively. We believe that these  amounts  appropriately reflect the risk of  E&O
inventory inherent in our business. The increase in the year ended September  30, 2015 as compared to
the year ended September 30, 2014 is primarily due  to  a $76.8 million charge relating to inventory
previously purchased in connection with a specific program  which was subsequently terminated and
deemed to have no alternative use, and our change in the estimation  methodology by which we
determine the E&O reserve for our hardware inventory  from an aging methodology to a consumption
methodology, see ‘‘—Change in Estimate—Inventory  E&O Reserve’’. The increase in the year ended
September 30, 2014 as compared to the year  ended September 30, 2013 is primarily  due to inventory
growth during the year. For a more detailed description of the E&O  reserves, see Note  5 of the Notes
to Consolidated Financial Statements in Part II, Item  8 of this Annual Report on Form 10-K.

The principal components of our selling, general and administrative expenses are salaries, wages,
benefits and bonuses paid to our employees; stock-based compensation;  commissions paid to outside
sales representatives; travel and other business  expenses; training and recruitment costs; marketing,
advertising and promotional event costs;  rent; bad debt  expense;  professional  services fees (including
legal, audit and tax); and ordinary day-to-day business expenses.  Depreciation and amortization expense
is also included in selling, general and administrative expenses, and consists  primarily of  scheduled
depreciation for leasehold improvements, machinery  and equipment, vehicles, computers, software and
furniture and fixtures. Depreciation and amortization also includes  intangible asset amortization
expense.

Other Expenses

Interest Expense, Net.

Interest expense, net consists of the interest we pay on  our long-term debt,

fees on our revolving facility (as defined below under ‘‘—Liquidity  and Capital Resources—Credit
Facilities—Senior Secured Credit Facilities’’) and our line-of-credit and  deferred financing costs, net of
interest income.

38

39

Other Income (Expense), Net. Other income (expense), net is primarily comprised of unrealized

foreign exchange gain or loss associated  with transactions denominated in currencies other  than the
respective functional currency of the  reporting subsidiary.

Critical Accounting Policies and Estimates

The methods, estimates and judgments  we use in applying  our most critical accounting policies

have a significant impact on the results  we report  in our financial statements. We evaluate our
estimates and judgments on an on-going  basis. We base our estimates on historical experience and on
assumptions that we believe to be reasonable  under the  circumstances.  Our  experience  and assumptions
form the basis for our judgments about  the carrying value of assets  and liabilities that are  not  readily
apparent from other sources. Actual results  may  vary  from what we anticipate,  and different
assumptions or estimates about the future could change our reported results. We believe  the following
accounting policies are the most critical  in  that  they  significantly affect our financial statements, and
they require our most significant estimates and complex  judgments.

Inventories

Our inventory is comprised solely of  finished goods.  Inventories  are stated at the lower  of  cost or
market. The method by which amounts are removed from inventory  are weighted average cost for  all
inventory, except for chemical parts for which  the first-in, first-out  method is used.

We  record provisions, as appropriate, to write-down E&O inventory to estimated net realizable
value. We charge cost of sales for inventory provisions to write down  our  inventory  to  the lower of cost
or estimated market value or to completely write-off  obsolete or excess inventory. Most of  our
inventory provisions relate to the write-off of excess quantities of  products, based on  our inventory
levels compared to assumptions about  future demand and market  conditions. Once inventory  has been
written-off or written-down, it creates  a new cost basis for the inventory that is not subsequently
written-up. The process for evaluating  E&O inventory often requires  us to make  subjective judgments
and estimates concerning future sales  levels, quantities and prices at which  such inventories will be able
to be sold in the normal course of business.

The components of our inventory are subject to different risks of  excess  quantities  or obsolescence.

Our hardware inventory, which does not  expire or have  a pre-determined  shelf life, bears a higher  risk
of excess quantities than of becoming obsolete. However, our  chemical inventory becomes obsolete
when it has aged past its shelf-life, cannot be recertified and is no longer usable or  able to be sold, or
the inventory has been damaged on-site  or in-transit. In such instances, a full reserve is taken against
such inventory.

In the three months ended September  30, 2015, we determined that  inventory  previously  purchased

in connection with a specific program  which  was subsequently  terminated, had no alternative use.
During  the year ended September 30, 2015, we continued to  negotiate a  sale of such inventory with  our
customer for whom such inventory was purchased, as well as market the inventory through other
channels, and believed the full cost of this  inventory was recoverable.  However, in  the fourth  quarter  of
2015, we determined such inventory was not marketable and recorded  a  reserve of  $33.0 million.

Demand  for our products can fluctuate significantly. Our estimates of future  product demand  and

selling prices may prove to be inaccurate,  in which case we may have  understated or overstated the
write-down required for E&O inventories. In  the future,  if our  inventories are determined  to  be
overvalued, we would be required to  recognize such costs in our cost  of  goods sold at the time of such
determination. Conversely, if our inventories  are determined to be undervalued, we  may have
over-reported our costs of goods sold in previous periods  and  would be required  to  recognize such
additional operating income at the time  of  sale.  As of September 30, 2015 and 2014, our E&O  reserve
was $264.1 million and $197.2 million,  respectively.  We  have revised the  previously reported  E&O

reserve as of September 30, 2014 of $143.7 million that  was not correct due  to  a clerical  error  in the
prior year footnote. This immaterial revision does not change  the inventory amount reported on the
balance sheet or the amount of E&O charges  recorded in the statement  of comprehensive  income.
Charges to cost of sales for the increase in our E&O reserves and  related items were $95.1 million,
$17.7 million, and $8.7 million in the  years  ended September 30,  2015, 2014 and 2013, respectively. We
believe that these amounts appropriately reflect the risk of E&O inventory inherent in our business.

Change in Methodology

During the year ended September 30, 2015, management  changed  the  methodology by which we
determine the E&O reserve for our hardware inventory  from an aging methodology to a consumption
methodology. In the three months ended  September 30, 2015,  we implemented this new strategy  of
providing integrated supply chain services more tailored to customer demand through long-term
contracts and focused forecasted consumption, including changes to our inventory purchasing strategy,
holding inventory for shorter periods and the  planned scrapping  of long dated inventory. The new
strategy and updates for fiscal 2015 sales activities led to changes  in the sell through rates, holding
period of aged inventory and others estimates used in the E&O reserve for our hardware inventory,
which increased our E&O inventory reserves by $43.8 million.

The Year Ended September 30, 2015

In conducting our E&O reserve for our hardware inventory, we consider  a variety of factors,
including historical sales over a five year period  which we utilize to forecast future demand. E&O
inventory is identified by comparing current inventory levels to future demand,  and is reserved
appropriately. We also stratify the inventory population in order to identify inventory  which is sold  to  a
single customer, and we therefore have  increased risk of holding excess or obsolete inventory should
the underlying contracts with that customer be terminated or otherwise not renewed.

We also consider a variety of factors, including shelf-life expiration, damage to products, rights we

have with certain manufacturers to exchange unsold  products for new products and open customer
orders.

The Years Ended September 30, 2014 and 2013

The E&O reserve included both excess  and  slow-moving inventory which typically included
inventory held by us after strategic purchases were made to take advantage of favorable pricing terms,
speculative purchases based on current market trends  or purchases timed to take supplier lead times
into account, which may have resulted  in us maintaining excess and slow-moving quantities  of
inventories.

In conducting our reserve analysis with respect to slow-moving inventory, we considered a variety
of factors, including historical sell-through rates,  selling and buying  patterns, inventory quantities and
aging, shelf-life expiration, damage to products, rights we had with certain manufacturers to exchange
unsold  products for new products and open customer orders. Furthermore, although  our customers
were not required to purchase a specific quantity of  inventory from us, we forecasted future sales by
monitoring and tracking our customers’ production cycles, which was taken  into  account when
conducting our reserve analysis.

Goodwill and Indefinite-Lived Intangible Assets

Goodwill represents the excess of the consideration paid over the fair value of the  net assets
acquired in a business combination. Goodwill and indefinite-lived intangible assets  acquired in a
business combination are not amortized, but instead tested for impairment at least annually or more
frequently should an event occur or circumstances indicate that the  carrying amount may be impaired.

40

41

Such events or circumstances may be a significant  change in business climate, economic  and industry
trends,  legal factors, negative operating  performance indicators, significant competition,  changes in
strategy, or disposition of a reporting unit or a portion thereof.  Goodwill and indefinite lived
intangibles impairment testing is performed at the reporting  unit level on July 1 of  each  year  and when
circumstances change that might indicate impairment.

We  test goodwill for impairment by performing  a qualitative assessment process, or using a

two-step quantitative assessment process. If we choose  to  perform  a qualitative assessment process and
determine it is more likely than not (that is, a likelihood of  more than  50 percent) that the carrying
value of the net assets is more than the  fair value of the reporting unit, the two-step quantitative
assessment process is then performed;  otherwise, no further testing is required. Factors utilized in the
qualitative assessment may include the  following:  macroeconomic conditions;  industry and  market
considerations; cost factors; overall financial performance; Wesco entity  specific  operating results  and
other relevant Wesco entity specific events.  We may elect not to perform  the qualitative  assessment
process and, instead, proceed directly  to  the two step quantitative assessment process.  For reporting
units where the two-step quantitative  assessment  process is performed, the first step involves comparing
the carrying value of net assets, including goodwill,  to  the fair value  of  the reporting unit. If the fair
value exceeds its carrying amount, goodwill  is not considered impaired and the  second step  of the
process is unnecessary. If the carrying amount of a reporting  unit’s goodwill exceeds its fair value, the
second  step measures the impairment  loss, if  any.

The first step identifies potential impairment by comparing  the fair  value of a  reporting unit with
its  carrying amount, including goodwill.  For periods  prior to the Haas acquisition, our reporting units
were consistent with our operating segments  (North America Hardware and Rest of World Hardware).
Subsequent to the  Haas acquisition, we added two  additional  reporting  units (North  America Chemical
and Rest of World Chemical). The estimates of fair value  of a reporting  unit are determined  based on
a discounted cash flow analysis and market earnings multiples. A discounted cash  flow analysis requires
us to make various judgmental assumptions, including assumptions  about  future cash flows, growth
rates and discount rates. The assumptions  about future cash flows  and growth rates are based on the
forecast and long-term business plans of  each  reporting unit. Discount rate  assumptions  are based on
an assessment of the risk inherent in  the future  cash flows  of  the respective reporting units. If the  fair
value exceeds the carrying value of a  reporting unit, goodwill is not  considered impaired and the
second  step of the test is unnecessary. If the  carrying amount of a  reporting unit’s goodwill exceeds the
fair value of a reporting unit, the second step measures  the impairment loss, if  any.

The second step compares the implied fair  value  of  goodwill with the carrying amount of that

goodwill. The implied fair value of goodwill is determined in the  same  manner  as the amount of
goodwill recognized in a business combination. The implied  fair value of the reporting  unit’s goodwill is
calculated by creating a hypothetical balance sheet  as if the reporting  unit had just been  acquired.  This
balance sheet contains all assets and  liabilities recorded  at fair value  (including any intangible assets
that may not have any corresponding carrying value  in our balance sheet).  The implied value of the
reporting unit’s goodwill is calculated by subtracting the  fair value of the net  assets from the  fair value
of the reporting unit. If the carrying  amount of goodwill exceeds the implied fair value  of  that  goodwill,
an impairment loss is recognized in an amount equal to that excess. We  performed  qualitative
assessments for the year ended September 30, 2014,  and  on a quarterly basis,  as needed, during the
year ended September 30, 2015.

For the North America Hardware reporting unit, we performed a Step 1 goodwill  impairment test

on July 1, 2012, which reflected fair value in excess of  carrying value of 38.5%.  Since 2012,  North
America Hardware has underperformed  relative to the forecasts  included in the  Step 1 analysis;
however, our Step 0 impairment tests performed  on July 1,  2013 and 2014 did not indicate it was more
likely than not that the carrying value exceeded the fair  value  of  the reporting unit. Through  June 30,
2015, we continued to monitor Wesco North America’s performance  relative to these forecasts.

We performed our Step 1 goodwill impairment tests on July 1,  2015. The results of these tests
indicated that the estimated fair values of our reporting units exceeded their carrying values,  with the
exception of the North America Hardware reporting unit within our North America segment reflecting
management’s reduced sales and earnings outlook. The impact of market pressures such as decreasing
revenue and underperformance relative to forecast adversely impacted the fair value  of this reporting
unit. As a result, we proceeded to Step  2 of the  goodwill impairment analysis, and compared the
implied value of North America Hardware’s goodwill with the carrying value  of its goodwill,  and since
the carrying value exceeded the implied fair value, we recorded a non-cash  impairment charge of
$263.8 million in the three months ended September 30, 2015.

The preparation of our internal forecasts requires significant judgments, including the estimation
of the long-term rate of growth for our business,  estimation of the  useful life over which cash flows will
occur, cost containment activities, changes  in working capital, growth rates, discount rates, and other
factors. Changes in these factors could significantly change our internal forecasts, which could
significantly change the amount of impairment  recorded, if any.

Revenue Recognition

We recognize product and service revenue when (1) persuasive evidence of an arrangement exists,

(2) title transfers to the customer, (3) the sales price charged is fixed or determinable and (4) collection
is reasonably assured. In instances where  title does not pass to the customer upon shipment, we
recognize revenue upon delivery or customer acceptance, depending on the  terms  of the  sales contract.

We report revenue on a gross or net basis  based on management’s assessment of whether we act

as a principal or agent in the transaction. We assess whether we  act as a principal in the transaction or
as an agent acting on behalf of others by considering such factors as to whether or not we obtain
control of the product, the form of consideration we receive, our ability to influence pricing, and our
performance obligations. Based upon  these criteria, if we are the principal in the transaction and have
the risks and rewards of ownership, the transactions are recorded as gross in the consolidated
statements of comprehensive income. If we do not act as a  principal in the transaction,  the transactions
are recorded on a net basis in the consolidated statements of comprehensive income. The majority of
our revenue is recorded on a gross basis with  the exception of certain gas, energy and chemical
manager service contracts that are recorded as net revenue.

We also enter into sales rebate and profit  sharing arrangements  with our customers. Such customer

incentives are accounted for as a reduction to gross sales and recorded based upon estimates at the
time products are sold. These estimates are based upon historical experience for similar programs and
products. We review such rebates and profit sharing arrangements on an ongoing  basis and accruals are
adjusted, if necessary, as additional information becomes available.

Management provides allowances for credits and  returns, based on historic experience, and adjusts

such allowances as considered necessary. To  date, such  provisions have been within the range of
management’s expectations and the allowance established.

Income Taxes

We recognize deferred tax liabilities and assets for the expected future  tax consequences of

temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred
income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which these temporary differences are expected to be recovered or settled. 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. A valuation allowance is established, when necessary, to
reduce net deferred tax assets to the amount  expected to be realized. The ultimate realization of
deferred tax assets depends upon the generation of future taxable income during the periods in which

42

43

temporary differences become deductible  or includible in  taxable income. We consider projected future
taxable income and tax planning strategies in our assessment.  Our foreign subsidiaries are taxed in local
jurisdictions at local statutory rates.

We  determine whether it is more likely than not that some  or all of the  deferred tax assets  will not

be realized. We have recorded valuation allowances of $6.0  million and $4.9  million as of
September 30, 2015 and 2014, respectively,  against certain  deferred tax assets,  which consist  primarily
of temporary differences related to certain  Haas foreign  tax  credits and Haas  foreign net operating
losses. The valuation allowances are based  on our estimates of taxable income by jurisdictions  in which
we operate and the period over which  our deferred  tax  assets  will be recoverable. If actual results differ
from these estimates or if we revise these estimates  in future periods,  we  may  need to adjust the
valuation allowances which could materially impact our financial position and results  of operations.

Stock-Based Compensation

We  account for all stock-based compensation awards to employees and members of our Board of
Directors based upon their fair values as  of the  date of  grant using a  fair value  method and recognize
the fair value of each award as an expense over the  requisite service period  using  the graded vesting
method for awards with performance conditions and the  straight  line method for  awards  with service
conditions only.

For purposes of calculating stock-based compensation, we estimate the fair value  of stock options

using a Black-Scholes option pricing  model, which requires the use of certain subjective assumptions
including expected term, volatility, expected dividend, risk-free  interest  rate, and the fair value  of  our
common stock. These assumptions generally  require significant judgment.

We  estimate the expected term of employee  options using the  average of the  time-to-vesting and

the contractual term. We derive our expected volatility from the  historical  volatilities  of several
unrelated public companies within our  industry  because we  have little  information  on the volatility of
the price of our common stock since  we have limited trading history.  When  making the selections  of
our  industry peer companies to be used  in the volatility calculation, we also  consider the  size and
financial leverage of potential comparable companies. These historical volatilities are  weighted  based
on certain qualitative factors and combined to produce  a single  volatility factor. Our expected  dividend
rate is zero, as we have never paid any dividends on our  common stock and do not anticipate any
dividends in the foreseeable future. We  base the risk-free interest rate on  the U.S.  Treasury yield in
effect at the time of grant for zero coupon U.S.  Treasury notes  with maturities approximately equal to
each  grant’s expected life. For awards  with performance conditions, we  estimate the  probability that the
performance condition will be met.

We  estimate our forfeiture rate based on  an analysis  of our actual forfeitures and will continue  to

evaluate  the appropriateness of the forfeiture rate  based on actual forfeiture experience, analysis of
employee turnover behavior and other factors. Quarterly changes in the  estimated forfeiture  rate can
have a significant effect on reported  stock-based compensation expense, as the cumulative effect of
adjusting the rate for all expense amortization is recognized  in the period the forfeiture estimate  is
changed.

The following table summarizes the amount of stock-based compensation expense recognized  in

our  consolidated statements of comprehensive  income  (in  thousands):

2013

For the years ending September 30, 2016 and 2017, we expect to incur stock-based compensation

expense of $5.5 million and $3.6 million,  respectively.

If any of the factors change and/or we employ different assumptions, stock-based compensation

expense may differ significantly from what we have recorded in the past. If there is a difference
between the assumptions used in determining stock-based compensation  expense and the actual factors
that become known over time, we may change  the input factors used in determining stock-based
compensation costs for future grants. Additionally, we may change the estimates that the performance
obligations may be met. These changes, if any, may materially impact our results of operations in the
period such changes are made. We expect to continue to grant stock options in the future,  and to the
extent that we do, our actual stock-based compensation expense recognized  in future periods will likely
increase.

Net Sales

Net sales for the year ended September  30, 2015 increased $141.7 million, or 10.5%, to
$1,497.6 million compared to the year ended September 30, 2014, driven by the Haas acquisition
completed on February 28, 2014, offset by the impact of a customer contract renegotiation, as described
below, and foreign currency movements. Sales  attributable to  the acquired Haas  business increased
$235.7 million for the year ended September 30, 2015 as  compared to the year ended September 30,
2014, which was a result of having a full year and seven months of Haas results included in the years
ended September 30, 2015 and 2014, respectively. During the year ended September 30, 2014,  we
modified and extended a contract with an existing customer that resulted in a $66.3 million reduction in
net sales to the customer during the year ended September 30, 2015  as compared  to the year ended
September 30, 2014. The year ended September 30, 2014 also included a $6.4 million settlement  related
to the termination of a separate contract. During the year ended  September 30, 2015,  foreign currency
movements negatively impacted sales by $25.4  million. Ad hoc  and Contract sales as a percentage of
consolidated net sales represented 26% and 74%, respectively, for the year ended September 30, 2015,

44

45

as compared to 28% and 72%, respectively, for  the year  ended September 30,  2014. The decrease  in  ad
hoc sales as a percentage of net revenue  was a  result of adding  a  full year of Haas  sales,  which has a
higher  percentage of Contract sales.

ended September 30, 2014. This decrease is primarily  due to loss from  operations  as a percentage of
net sales for fiscal 2015, as discussed above, which was partially offset by income tax benefit for
operating losses.

(Loss) income from Operations

Year ended September 30, 2014 compared with the year  ended September 30, 2013

Loss from operations for the year ended  September 30,  2015  was $206.4 million, compared to
income from operations of $183.9 million for the  year  ended September 30,  2014. Loss from operations
was 13.8% of net sales for the year ended September 30,  2015, compared to income from  operations  of
13.6% of net sales for the year ended September 30, 2014. The dollar  decrease  in income from
operations was comprised of a decrease  in  gross profit of $78.5  million, an increase in selling, general
and administrative expenses of $48.0  million and a goodwill impairment charge of $263.8  million.  The
decrease in gross profit was primarily driven by a $95.1 million  increase in  E&O inventory reserve,
which  was largely the result of our change of E&O  reserve estimation methodologies (see further
discussion under ‘‘—Critical Accounting  Policies and  Estimates—Inventories’’), and lower-margin
Contract sales partially offset by additional  gross profit as a result of the Haas acquisition. The increase
in selling, general and administrative  expenses  was  primarily driven by $32.6  million of  additional
expenses as a result of the Haas acquisition and increases in professional fees, payroll costs, stock-based
compensation, restructuring costs and  depreciation expense of $8.2  million, $4.7 million,  $2.4 million,
$4.5 million and $1.3 million, respectively.  These increases were  partially  offset by lower  integration
related costs of $5.8 million.

Other  Expenses

Interest Expense, Net

Interest expense, net was $37.1 million for the year ended  September 30, 2015,  which increased
$7.9 million, or 26.9%, compared to  the year ended  September 30, 2014.  $7.1 million of this increase
resulted from having a full year of interest during fiscal 2015 compared to seven months  of interest
during fiscal 2014 on the term loan B facility (as defined below under  ‘‘—Credit  Facilities—Senior
Secured Credit Facilities’’), which was  used to fund the Haas acquisition in February 2014.

Other Income, Net

Other income, net was $1.8 million for the year ended  September 30, 2015, which decreased by

$0.4 million compared to the year ended September 30,  2014. This change was primarily due to
unrealized foreign currency exchange losses associated with  transactions denominated in  currencies
other than the respective functional currency  of the reporting  subsidiary.

Benefit (Provision) for Income Taxes

The income tax benefit was $86.9 million  for the  year ended September 30,  2015, compared  to  the
income tax provision of $54.8 million for  the year  ended September 30, 2014. Our effective tax  rate was
36.0% and 34.9% for the years ended  September 30, 2015  and 2014,  respectively.  The  increase in our
effective tax rate resulted primarily from  an impairment  of  certain goodwill and adjustments to our
E&O inventory reserve. Refer to Note 15  of the Notes to Consolidated Financial  Statements in  Part II,
Item 8 of this Annual Report on Form 10-K for additional information  about our benefit  for income
taxes for the year ended September 30,  2015.

Net (Loss) Income

We  reported a net loss of $154.7 million for the year ended September  30, 2015, compared to a
net income of $102.1 million for the  year  ended September 30,  2014. Net loss was 10.3%  of  net sales
for the year ended September 30, 2015, as  compared to net income of 7.5%  of net sales for  the year

Net Sales

Net sales of $1,355.9 million for the year ended  September 30, 2014  increased  $454.3 million, or

50.4%, compared to the year ended September 30, 2013. Ad hoc and  Contract  sales as a percentage of
net sales represented 28% and 72%, respectively, for  the year ended September 30, 2014, as compared
to 40% and 60%, respectively, for the year ended September 30, 2013. The increase in Contract sales
as a percentage of net sales for fiscal 2014 was resulted from  Haas sales, which  had a higher
percentage of Contract sales. The year ended  September 30, 2014  reflects $356.2 million of net  sales
related to the Haas acquisition, and exclusive of these net sales the increase in net sales would have
been $98.1 million, or 10.9%.

Income from Operations

Income from operations of $183.9 million for the year ended September  30, 2014 increased
$3.1 million, or 1.7%, compared to the year ended September 30, 2013. Income from operations as a
percentage of net sales was 13.6% for the year ended September 30, 2014, compared to 20.1% for the
year ended September 30, 2013. The dollar  increase in income from  operations was  comprised of  an
increase  in gross profit of $85.3 million offset by an increase in selling, general and administrative
expenses of $82.2 million. The increase in gross profit was primarily  driven by additional gross profit as
a result of the Haas acquisition, partially offset by a $8.6 million  increase in the E&O inventory reserve
(exclusive of the impact of the Haas acquisition)  as well as the impact of increased lower-margin
Contract  sales and discounts provided to customers in  exchange for long-term contract extensions. The
increase  in selling, general and administrative expenses was primarily driven by $58.6 million of
additional expenses as a result of the  Haas acquisition, $12.6 million of integration related costs
associated with the Haas acquisition and increases in payroll costs,  stock-based compensation, group
insurance, depreciation and commissions of $4.3 million, $2.1 million, $1.3 million, $1.0  million and
$1.0 million, respectively.

Other Expenses

Interest Expense, Net

Interest expense, net of $29.2 million for the year ended  September 30, 2014 increased

$4.0 million, or 16.1%, compared to the year ended September 30, 2013. This increase was driven by
$12.1 million of interest incurred for the year  ended September 30, 2014 associated with the term loan
B facility and the revolving facility that  were used to fund the Haas  acquisition.  This increase was
partially offset by lower interest due to a reduction in the average  term loan A facility  balance of
$26.7 million for the year ended September 30, 2014 as  compared to September 30, 2013, as well as
$5.0 million write-off of deferred financing charges related to the refinancing of the old  senior  secured
credit facilities (as defined below under ‘‘—Liquidity and  Capital Resources—Credit Facilities—Old
Senior Secured Credit Facilities’’) during  the year ended September  30, 2013.

Other Income (Expense), Net

Other income, net of $2.2 million for the year ended September 30,  2014 increased by $0.2 million

compared to the year ended September 30, 2013.  This  change was primarily due to unrealized foreign
exchange gains associated with transactions denominated  in currencies other than the respective
functional currency of the reporting subsidiary.

Provision for Income Taxes

Provision for income taxes of $54.8 million  for  the year  ended September 30, 2014 increased by
$2.0 million compared to the year ended September 30,  2013. Our  effective tax  rate was  34.9% and
33.5% for the years ended September  30, 2014  and 2013, respectively. The increase in our effective tax
rate resulted primarily from an increase in certain expenses related to the Haas  acquisition  which are
not tax deductible. Refer to Note 15  of  the Notes to Consolidated Financial Statements in  Part  II,
Item 8 of this Annual Report on Form 10-K for additional information  about our provision for  income
taxes for the year ended September 30,  2014.

Net Income

We  reported net income of $102.1 million for the year ended September 30, 2014,  compared to net

income of $104.8 million for the year  ended September 30, 2013.  Net income as a  percent of net sales
decreased 4.1% for the year ended September  30, 2014, as compared to the year ended  September 30,
2013, due to lower income from operations  as a percentage of net  sales,  as discussed above,  partially
offset by lower interest expense as a percent of net  sales  and a  lower provision  for income taxes as a
percent of net sales.

Net Sales

Net sales of $1,198.2 million from our  North America  segment for the year ended September 30,

2015 increased $167.7 million, or 16.3%,  compared to the year  ended  September 30, 2014, reflecting  an
increase of $189.7 million driven by the Haas acquisition, partially  offset  by  a customer  contract
modification and the settlement related to the termination of a  contract that took place  during the year
ended September 30, 2014.

Ad hoc sales decreased by $4.0 million,  or 1.1%, and Contract sales  increased by $171.8 million, or
25.3%, primarily due to the addition of Haas,  which has  a higher percentage of Contract sales than  ad
hoc sales.

(Loss) Income from Operations

Loss from operations of our North America segment for the year ended September 30, 2015  was

$222.7 million, compared to an income from operations of $145.4 million for the year ended
September 30, 2014. Loss from operations was 18.6%  of  net sales for the year ended September  30,
2015, compared to an income from operations of 14.1% of net sales  for the year ended September 30,
2014. The dollar decrease in income  from operations  was  comprised of a decrease in  gross profit  of
$67.7 million, an increase in selling, general  and  administrative expenses of $36.6 million and a goodwill

impairment charge of $263.8 million. The decrease  in gross profit was primarily driven by an
$83.7 million inventory adjustment and increased lower-margin Contract sales, partially offset by
additional gross profit as a result of the Haas acquisition. The increase in selling,  general and
administrative expenses was primarily driven  by $22.8 million  of  additional expenses as a result of the
Haas acquisition and increases in professional fees, payroll  costs,  stock-based compensation,
restructuring costs and depreciation expense of $8.3 million, $3.9  million, $2.4 million, $2.6 million and
$1.5 million, respectively. These increases were partially offset by lower integration related costs of
$6.0 million.

Year ended September 30, 2014 compared with the year  ended September 30, 2013

Net Sales

Net sales of $1,030.5 million from our North America  segment for the year ended September 30,

2014 increased $316.8 million, or 44.4%, compared to the year  ended September 30, 2013. The year
ended September 30, 2014 reflects $266.3  million  of  net sales  related  to  the Haas acquisition, and
exclusive of these net sales North America net sales would have increased by $50.6 million, or 7.1%.
Excluding the Haas acquisition, ad hoc and Contract net sales  increased by $7.1 million or 2.3% and
$46.9 million or 11.7%, respectively, for the year ended September 30, 2014 as compared  to  the year
ended September 30, 2013. The increase in ad hoc net sales was primarily due to general growth across
numerous customers. The increase in Contract net sales was primarily driven  by  a transition of a
contract from Rest of World to North America, a settlement  related to the  termination of a contract,
increases in commercial build rates for existing Contracts and scope expansion on existing Contracts.

Income from Operations

Income from operations in our North  America segment for the year  ended September 30, 2014

was $145.4 million, which decreased $5.2  million, or 3.5%, compared to the year ended September 30,
2013. Income from operations as a percentage of net  sales in our  North  America segment was  14.1%
for the year ended September 30, 2014, compared to 21.1% for the year ended September 30, 2013, a
decrease of 7.0%. The dollar decrease in income from operations was comprised of an increase in gross
profit of $56.6 million offset by an increase in  selling, general and administrative expenses of
$61.8 million. The increase in gross profit was primarily driven by additional gross profit as a result of
the Haas acquisition, partially offset by a $8.6  million  increase in the E&O inventory reserve (exclusive
of the impact of the Haas acquisition), as well  as the impact of increased lower-margin Contract sales
and discounts provided to customers in exchange for long-term contracts  extensions. The increase in
selling, general and administrative expenses was primarily driven by $41.4 million of additional  expenses
as a result of the Haas acquisition, $12.6 million of integration -related  costs associated with the Haas
acquisition and increases in payroll costs, stock-based compensation, group insurance and depreciation
of $2.8 million, $2.1 million, $1.3 million  and $0.9 million,  respectively.

Net Sales

Net sales of $299.4 million from our  Rest  of World segment for the year ended  September 30,
2015 decreased $26.0 million, or 8.0%,  compared to the year  ended  September 30, 2014, reflecting
negative foreign currency impacts of  $25.4 million and a customer contract modification, partially offset
by additional Haas sales of $46.1 million.  Ad hoc sales decreased by $0.4  million, or 0.9%, and
Contract sales decreased by $25.6 million, or 9.1%, primarily due to the customer contract modification
and foreign currency impacts.

Income from Operations

Income from operations of our Rest of World segment for the year  ended  September 30,  2015 was

$16.4 million, which decreased $22.2  million, or  57.6%, compared to the year  ended September  30,
2014. Income from operations as a percentage of net  sales in our  Rest of World segment  was 5.5% for
the year ended September 30, 2015,  compared  to  11.9% for  the year ended  September 30, 2014. The
dollar decrease in income from operations was comprised of a  decrease in gross  profit of $10.8 million
and an increase in selling, general and administrative  expenses of  $11.4 million.  The  decrease in gross
profit was primarily driven by an $11.3 million inventory  adjustment and increased  lower-margin
Contract sales, partially offset by $12.4  million of additional  gross profit as a  result of the  Haas
acquisition. The increase in selling, general and administrative expenses was  primarily driven by
$10.8 million of additional expenses as a result of the Haas  acquisition  and increases in payroll costs
and commissions of $0.8 million and $0.6  million, respectively.

Year ended September 30, 2014 compared  with the  year  ended September 30, 2013

Net Sales

Net sales of $325.4 million from our  Rest  of World segment for the year ended  September 30,
2014 increased $137.5 million, or 73.2%,  compared to the year  ended  September 30, 2013. The year
ended September 30, 2014 reflects $90.0  million  of  net sales  related  to  the Haas acquisition, and
exclusive of these net sales Rest of World  net sales would have increased by $47.5 million, or 25.3%.
Excluding the Haas acquisition, ad hoc and Contract net sales  increased by $3.0 million or 6.7%  and
$45.3 million or 31.8%, respectively,  for  the year ended  September 30, 2014  as compared  to  the year
ended September 30, 2013. The ad hoc  net sales growth  was  attributable to increases  in European
production and growth across the customer  base  due  to  build rate increases and expansion of the MRO
market. The drivers of the increase in Contract sales were a one-time inventory  sale in conjunction with
the modification and extension of a contract with an existing customer as well as further growth of the
Boeing 787 production and higher build  rates  with European commercial customers. These increases
were partially offset by a transition of a contract  to  North  America.

Income from Operations

Income from operations of our Rest of World segment for the year  ended  September 30,  2014 was
$38.6 million, which increased $8.4 million,  or 27.7%, compared to the year  ended September  30, 2013.
Income from operations as a percentage of net sales in  our Rest of World segment was 11.9% for the
year ended September 30, 2014, compared to 16.1%  for the year  ended September  30, 2013, a  decrease
of 4.2%. The dollar increase in income from operations was comprised of an increase in gross profit  of
$28.8 million, partially offset by an increase in  selling, general and administrative  expenses of
$20.4 million. The increase in gross profit was primarily driven by additional gross profit as a result  of
the Haas acquisition, partially offset by  the impact of strong growth  in lower-margin Contracts sales.
The increase in selling, general and administrative  expenses was primarily driven by $17.1 million of

additional expenses as a result of the  Haas acquisition and increases in payroll costs and commissions
of $1.5 million and $1.0 million, respectively.

Liquidity and Capital Resources

Overview

Our primary sources of liquidity are cash flow from operations and available  borrowings under our

revolving facility (as defined below under ‘‘—Credit Facilities—Senior Secured Credit Facilities’’). We
have historically funded our operations, debt payments, capital  expenditures and discretionary funding
needs from our cash from operations. We had total available cash and cash equivalents  of $82.9 million
and $104.8 million as of September 30, 2015 and 2014, respectively, of which $30.8 million, or 37.2%,
and $56.0 million, or 53.5%, was held by our foreign subsidiaries as of  September 30, 2015 and 2014,
respectively. None of our cash and cash equivalents consisted  of  restricted cash  and cash equivalents as
of September 30, 2015 or 2014. All of our foreign cash and cash equivalents are readily convertible  into
U.S. dollars or other foreign currencies. Our  strategic plan does  not  require the repatriation of  foreign
cash in order to fund our operations in the U.S. and it is our current  intention to permanently reinvest
our foreign cash and cash equivalents outside of the U.S.  If we were to repatriate  foreign cash to the
U.S., we may be required to accrue and pay  U.S. taxes  in accordance with applicable U.S.  tax rules and
regulations as a result of the repatriation. Our primary uses of cash are for:

• operating expenses;

• working capital requirements to fund  the growth of our business;

• capital expenditures that primarily relate to IT equipment and our warehouse operations;

• debt service requirements for borrowings under the Credit Facilities (as defined below under

‘‘—Credit Facilities—Senior Secured Credit Facilities’’); and

• strategic acquisitions.

Generally, cash provided by operating activities has been adequate to fund our operations. Due to
fluctuations in our cash flows and the growth in our operations, it may be necessary from time to time
in the future to borrow under our revolving  facility to meet cash  demands. We anticipate that cash
provided by operating activities, cash and cash equivalents and borrowing capacity under our revolving
facility will be sufficient to meet our cash requirements  for  the  next twelve months.  As of
September 30, 2015, we did not have any material capital expenditure commitments.

Credit Facilities

Senior Secured Credit Facilities

Our amended credit agreement provides for (1) a $625.0 million term loan A  facility (the term

loan A facility), (2) a $200.0 million revolving credit facility  (the revolving facility), and (3) a
$525.0 million senior secured term loan B facility (the term loan B facility). We  refer to the term loan
B facility, together with the term loan  A facility and the revolving facility, as the Credit Facilities. The
Credit Facilities allowed us to acquire  Haas and for Wesco Aircraft Hardware Corp. to incur additional
first lien indebtedness and corresponding liens in the form of the term loan B facility and to reset
certain ratios with respect to the Consolidated Total Leverage Ratio covenant applicable to the term
loan A facility and the revolving facility, as further  described below.

As of September 30, 2015, our outstanding indebtedness under our Credit Facilities was

$952.9 million, which consisted of (1) $477.3 million of indebtedness under the term loan A facility, and
(2) $475.6 million of indebtedness under the term loan B facility. As of September 30, 2015,

50

51

$200.0 million was available for borrowing under  the revolving facility without  breaching any covenants
contained in the agreements governing  our  indebtedness.

The interest rate for the term loan A  facility is based on  our Consolidated  Total Leverage  Ratio

(as such ratio is defined in the Credit  Facilities) as  determined  in the  most recently delivered financial
statements, with the respective margins  ranging  from 1.75% to 2.50% for Eurocurrency loans and
0.75% to 1.50% for alternate base rate  (ABR) loans. The term loan A facility amortizes  in equal
quarterly installments of 1.25% of the  original principal amount of $625.0 million  for the  first  year,
escalating to quarterly installments of 2.50% of the original principal amount of $625.0 million by the
fifth year, with the balance due at maturity on December  7, 2017. As of September  30, 2015, the
interest rate for borrowings under the  term loan A facility  was 2.72%.

The interest rate for the term loan B facility  has a  margin of 2.50% per annum for  Eurocurrency

loans (subject to a minimum Eurocurrency rate  floor  of  0.75% per annum) or 1.50%  per  annum for
ABR loans (subject to a minimum ABR floor of 1.75% per  annum). The  term loan B  facility amortizes
in equal quarterly installments of 0.25% of the  original  principal amount of $525.0 million, with the
balance due at maturity on February  28,  2021. As of September 30,  2015, the interest rate for
borrowings under the term loan B facility was 3.25%. In July 2015,  we entered into interest rate swap
agreements relating to this indebtedness,  which  are described  in greater detail  in Note  12 of the Notes
to Consolidated Financial Statements in  Part II, Item  8 of this  Annual  Report on Form 10-K.

The interest rate for the revolving facility  is based on our Consolidated Total  Leverage Ratio as

determined in the most recently delivered  financial statements,  with the respective  margins ranging
from 1.75% to 2.50% for Eurocurrency  loans  and  0.75% to 1.50% for ABR loans. The revolving  facility
expires on December 7, 2017.

Our borrowings under the Credit Facilities are  guaranteed by us and  all of our direct  and indirect,
wholly-owned, domestic restricted subsidiaries (subject to certain exceptions) and secured  by  a first lien
on substantially all of our assets and  the assets of  our guarantor  subsidiaries, including capital stock of
the subsidiaries (in each case, subject  to  certain exceptions).

During  the year ended September 30, 2015, we made  voluntary prepayments totaling $50.0 million

on our term loan A facility and $36.3  million  on our term loan B facility, which  have been applied to
future required quarterly payments, and  we therefore have no required  payments in fiscal 2016.

Under the terms and definitions applicable to the Credit Facilities as  of September 30,  2015, our

Consolidated Total Leverage Ratio (as such ratio is defined in the Credit Facilities) cannot exceed 4.75
(with step-downs on such ratio during future  periods) and our Consolidated Net Interest  Coverage
Ratio (as such ratio is defined in the  Credit Facilities)  cannot be less than  2.25. The Credit Facilities
also contain customary negative covenants, including  restrictions on our and our restricted subsidiaries’
ability to merge and consolidate with  other companies, incur indebtedness, grant  liens or  security
interests on assets, make acquisitions,  loans, advances  or investments, pay dividends, sell or otherwise
transfer assets, optionally prepay or modify  terms of any junior indebtedness  or enter into transactions
with affiliates. As of September 30, 2015,  we were in compliance with all of  the foregoing covenants,
and our Consolidated Total Leverage  Ratio was  4.35 and  our  Consolidated  Net Interest Coverage  Ratio
was 6.13. As noted above, our Consolidated  Total Leverage Ratio  will step-down  during future periods,
decreasing to 4.50 for the quarter ending  December 31,  2015, 4.00 for  the  quarter  ending March 31,
2016 and 3.75 for the quarter ending  June  30, 2016 and thereafter.

Although our sales and earnings outlook meets the  projected  requirements for these covenants by
a narrow margin, ongoing analysis of forecast projections will be utilized to assess when and if  actions
and countermeasures are necessary, including  potentially seeking an  appropriate  covenant waiver  or
amendment. A breach of any of these  covenants  could  result in  an event of default under  the Credit
Facilities. If any such event of default  occurs, the lenders  under the  Credit  Facilities  may elect to

declare all outstanding borrowings, together with accrued interest and other amounts payable
thereunder, to be immediately due and payable. The lenders under the  Credit Facilities also have the
right in these circumstances to terminate any commitments they have to provide  further borrowings. In
addition, following an event of default under  the Credit Facilities, the lenders under those facilities will
have the right to proceed against the collateral granted to them to secure  the debt, which includes our
available cash. If the debt under the Credit  Facilities was to be accelerated,  our assets would not be
sufficient to repay in full our debt.

Old Senior Secured Credit Facilities

Our old senior secured credit facilities,  which were repaid on December 7, 2012 in connection with

our entry into the Credit Facilities described above, consisted of a (1) $150.0 million revolving facility
(the old revolving credit facility), (2) $265.0 million term loan A facility  (the old term loan A facility),
and (3) $350.0 million term loan B facility (the old term loan B facility).

The interest rate for the old term loan  A facility was based on our total consolidated net  leverage
ratio as determined in the most recently delivered financial  statements  at such time, with the respective
margins ranging from 2.25% to 3.25% for Eurocurrency loans and 1.25% to 2.25% for ABR loans. The
old term loan A facility amortized in equal quarterly installments of  1.25% of the original principal
amount of $265.0 million for the first year, escalating to quarterly installments of 3.75% of the original
principal amount of $265.0 million by the fifth year, with the final payment due on April 7, 2016. The
applicable margin for the old term loan B facility was based on our total consolidated net leverage
ratio as determined in the most recently delivered financial  statements  at such time, with the respective
margins ranging from 2.75% to 3.00% for Eurocurrency loans and 1.75% to 2.00% for ABR loans.
However, at no time could the Eurocurrency Rate or the ABR be less than 1.25%. The old term
loan B facility amortized in equal quarterly installments of 0.25% of the original principal amount of
$350.0 million. The remaining balance was due on April 7,  2017.

The old revolving credit facility would have expired on April 7,  2016. The applicable margin was

based on the total net leverage ratio as determined in the most recently delivered financial statements
at such time, with the respective margins ranging from 1.25% to 2.25% for the ABR loans and 2.25%
to 3.25% for the Eurocurrency loans. From September 30,  2012 through December 7,  2012, we paid
$0.1 million in commitment fees for this line  of  credit.

UK Line of Credit

As of September 30, 2015, our subsidiary, Wesco Aircraft  Europe, Ltd, has available a £7.0 million
($10.6 million based on the September 30, 2015 exchange rate) line of credit that automatically renews
annually on October 1. The line of credit bears interest based on the base rate plus an applicable
margin of 1.65%. As of September 30, 2015, the full £7.0 million was available for borrowing under the
UK Line of Credit without breaching  any  covenants contained in the agreements  governing our
indebtedness.

Operating Activities

Our operating activities generated $141.7 million of cash in the  year ended September 30,  2015, an

increase of $88.0 million as compared to the  year  ended September 30,  2014. During the year ended
September 30, 2015, net loss adjusted for  non-cash items provided cash of $119.8 million.  During  the
year ended September 30, 2014, net  income adjusted for non-cash  items provided cash of
$143.4 million. This decrease of $23.6  million of cash generated from results  of operations  is due
primarily to a lower gross profit and higher selling,  general and administrative expenses.  The
$23.6 million decrease is more than offset by higher cash generated by working capital of $93.0  million,
taxes of $10.3 million, and accrued expenses and other liabilities of $12.3 million,  partially  offset by a
use of cash of $4.5 million from prepaid  expenses.

Working capital improvement was due primarily to higher cash generated  by  accounts receivable of

$82.4 million, driven by improved cash collections and lower  net  sales, and $23.7  million  lower in
inventory investment during the year  ended September 30,  2015 as compared  to  the year ended
September 30, 2014, partially offset by  a  use of cash of $13.1 million from accounts payable.

Our operating activities generated $53.7 million of cash in the  year ended September 30,  2014, a

decrease of $31.1 million as compared  to  the year ended  September 30, 2013. This  decrease was
primarily the result of a $16.2 million  use  of  cash  related to accounts payable due to the timing  of
payments and inventory receipts, as well as $16.9 million use of cash  related to income tax receivable as
a result of the prior year receivable being  depleted and  consequently requiring payments  to  be  made in
the year ended September 30, 2015.  Other drivers  of  the decrease in cash  from operating activities
were a $11.6 million increase in the change in accounts receivables driven by an  increase in sales of
$22.9 million, or 9.8%, during the three months ended September  30, 2014 (exclusive of the Haas
acquisition) as compared to the three months  ended September 30,  2013. Offsetting  these  decreases
was a $17.6 million decrease in the change  in inventory driven by  higher sales during  the three months
ended September 30, 2014 as compared to the three months ended September 30, 2013.

Investing Activities

Our investing activities used $9.9 million, $571.5  million and $7.9 million of  cash in  the years
ended September 30, 2015, 2014 and  2013,  respectively. During the  year ended September 30,  2014,
$560.2 million was used for the Haas  acquisition.  The remaining amounts in the  years  ended
September 30, 2015, 2014, and 2013 were primarily used for  investments in  various capital expenditures
and to purchase property and equipment.

Financing Activities

Our financing activities used $150.7 million  of  cash  in the year ended September 30, 2015.  This
was primarily due to $149.8 million repayments of our  long-term debt  and  $1.5 million repayment  of
our  capital lease obligations.

Our financing activities generated $543.0 million  of cash  in the year ended  September 30, 2014.
This was primarily due to $565.0 million  of  borrowings to fund the Haas acquisition. Other drivers were
$10.2 million in excess tax benefit related  to stock options exercised  and $9.6 million  of proceeds
received in connection with the exercise  of  stock options. These  amounts were partially offset by
$10.2 million of financing fees paid in  connection  with the borrowings to fund the Haas  acquisition,
$30.3 million used to repay principal against the Credit Facilities  and  $1.3 million  used to make
principal payments under our capital  lease obligations.

Our financing activities used $58.1 million  of  cash  in the year ended September 30, 2013.  These

cash outflows were driven by the repayment of long-term debt of $683.0 million,  $7.3 million in
financing fees related to new borrowings  and the  cash settlement  of  restricted stock tax withholding of

$8.5 million. The cash outflow was partially offset  by $625.0 million in new borrowings, $9.9 million
related to proceeds from stock options exercised and a $6.9 million excess tax benefit related to vested
restricted stock units and stock options  exercised.

(1) Includes both principal and estimated variable interest expense  payments.  The interest rate used to

calculate the estimated future variable interest expense is  based on  the actual interest rate
applicable to the Company’s indebtedness  as of September 30, 2015, which was 2.72% for the term
loan A and 3.25% for the term loan B. The actual  variable interest expense paid by the  Company
in the future may vary from what is presented above. Investors  should refer  to the ‘‘Management’s
Discussion and Analysis of Financial Condition  and Results of Operations—Liquidity  and Capital
Resources—Credit Facilities—Senior Secured Credit Facilities’’ and ‘‘Quantitative and Qualitative
Disclosures About Market Risk—Interest Rate  Risk’’ for additional information.

(2) Other long-term liabilities primarily include long-term hedge liabilities, noncurrent income taxes
payable and noncurrent deferred tax liabilities. Due to the  uncertainty in the timing of future
payments, long-term hedge liabilities of approximately $4.1 million, uncertain tax positions of
approximately $3.1 million and noncurrent deferred tax liabilities of approximately $30.7 million
were presented as one aggregated amount in the total  column on a separate line in this table.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT  MARKET RISKS

Our exposure to market risk consists of foreign currency exchange rate fluctuations, changes  in

interest rates and fluctuations in fuel  prices.

Foreign Currency Exposure

Foreign Currency Translation

During  the years ended September 30, 2015 and 2014,  20% of our net sales were made  by  our
foreign subsidiaries, and our total non-U.S.  net sales represented 34% and 43%, respectively, of our
total net sales. As a result of these international operating activities, we  are exposed to risks associated
with changes in foreign currency exchange rates, principally foreign currency exchange rates between
the U.S.  dollar, British pound, the Euro, Canadian dollar  and the  Mexican peso.

The results of operations of our foreign subsidiaries are  translated into U.S. dollars at the average

foreign currency exchange rate for each relevant  period. This translation has no impact on  our  cash
flow. However, as foreign currency exchange rates change, there  are  changes to the U.S. dollar
equivalent of sales and expenses denominated in foreign currencies. Any adjustments resulting from the
translation are recorded in accumulated other comprehensive income on our statements of changes in
stockholders’ equity. We do not consider the risk associated with foreign currency exchange rate
fluctuations to be material to our financial condition  or results of operations.

A hypothetical 10% decrease in the value of the British pound, the Euro, the Canadian dollar and

the Mexican peso relative to the U.S.  dollar would  have impacted our consolidated net loss with an
increase of $1.5 million, a decrease of $0.4  million,  no change and an  increase of $0.2 million,
respectively, during the year ended September 30,  2015. A hypothetical 10% increase in the value of
the British pound, the Euro, the Canadian dollar  and  the Mexican peso relative to the  U.S. dollar
would have impacted our consolidated  net loss with  a decrease of $1.5 million,  an increase of
$0.4 million, no change and an decrease  of $0.2  million,  respectively, during the  year  ended
September 30, 2015.

Foreign Currency Transactions

Foreign currency transaction exposure arises where  actual sales and  purchases are made by a
company in a currency other than its  own  functional  currency. During  the year ended September  30,
2015, our subsidiaries in the United Kingdom had  sales  in U.S. dollars and Euros of $161.3 million and
A7.6 million (equivalent of $8.7 million), respectively, and  had  purchases in U.S. dollars and Euros of
$91.1 million and A26.1 million (equivalent of $30.0 million),  respectively. During the year ended
September 30, 2014, our subsidiaries in the United  Kingdom had sales in U.S. dollars  and Euros of
$231.0 million and A9.5 million (equivalent of $12.9 million),  respectively, and had  purchases in U.S.
dollars and Euros of $128.0 million and A32.2 million (equivalent of $43.7 million),  respectively. During
the year ended September 30, 2015,  our  subsidiary in Canada had sales in  Canadian  dollars of
$5.4 million (equivalent of $4.4 million)  and had purchases  in Canadian  dollars of $0.5  million
(equivalent of $0.4 million). During the year ended  September 30, 2014,  our  subsidiary in Canada had
sales in Canadian dollars of $4.8 million (equivalent of $4.4 million) and had purchases in Canadian
dollars of $0.3 million (equivalent of $0.3 million). During the year ended  September 30, 2015, our
subsidiaries in Mexico and Israel had purchases in  U.S. dollars  of $71.9 million and purchases in  Israeli
shekels of $27.7 million (equivalent of $7.1 million).  During  the year ended September  30, 2014, our
subsidiaries in Mexico and Israel had purchases in  U.S. dollars  of $8.0 million and purchases in  Israeli
shekels of 20.4 million (equivalent of $5.8  million).  To the  extent possible,  we structure arrangements
where  the purchase transactions are  denominated in U.S. dollars in order to minimize near-term
exposure to foreign currency exchange  rate fluctuations.

From September 30, 2014 to September 30, 2015, the U.S.  dollar strengthened  slightly against the

pound by $0.15 (from $1.66 to $1.51). From September 30, 2013 to September 30, 2014, the U.S. dollar
weakened against the pound by $0.10 (from $1.56 to $1.66). A strengthening of the U.S. dollar means
we realize a lesser amount of U.S. dollar  revenue on sales that were denominated in British pounds,
whereas a weakening of the U.S. dollar means we realize a greater amount of U.S. dollar revenue on
sales that were denominated in British  pounds. As a  result of  the  slight movement of the U.S. dollar
during the years ended September 30, 2015 and 2014, transactions denominated in foreign currencies
did not have a material impact on our financial  results during those periods.  A hypothetical 10%
increase  or decrease in the value of the British pound relative to the U.S. dollar would have resulted in
an increase or decrease in our net income  of $1.3 million, during the  year ended September 30, 2015,
attributable to our transactions denominated in foreign currencies.

We have historically entered into currency forward and  option contracts to limit exposure to
foreign currency exchange rate changes and  will  continue to monitor our  exposure to foreign currency
exchange rate changes. Gains and losses on  these  contracts  are  deferred until the transaction being
hedged is finalized. As of September 30, 2015, we had no  outstanding currency forward and option
contracts. We do not enter into currency forward and option contracts for trading  or speculative
purposes.

Interest Rate Risk

Our principal interest rate exposure relates to our Credit Facilities, which bear interest at a
variable rate. See Part II, Item 7. ‘‘Management’s Discussion and Analysis of Financial Condition  and
Results of Operations—Liquidity and Capital Resources—Credit Facilities—Senior Secured Credit
Facilities.’’ If interest rates rise, our debt service obligations on the borrowings under the Credit
Facilities would increase even though the amount borrowed remained the same, which would affect our
results of operations, financial condition  and liquidity. At our debt level and  borrowing rates for the
years ended September 30, 2015 and 2014, our interest expense, including fees under our revolving
facility, was $29.1 million and $32.9 million, respectively. If variable interest rates were to change by
1.0%, our interest expense would fluctuate $9.5  million  per  year, without taking  into  account the effect
of any hedging instruments.

We periodically enter into interest rate  swap agreements to manage interest rate risk on our
borrowing activities. In July 2015, we entered into interest rate swap agreements which effectively fix
our interest rate on variable rate debt of $475.0 million to 1.21% plus the applicable margin. See
further discussion on our derivative financial  instruments in  Note 12 of the Notes to Consolidated
Financial Statements in Part II, Item 8 of this Annual Report on Form 10-K.

We do not hold or issue derivative financial instruments for trading  or speculative purposes.

Fuel Price Risk

Our principal direct exposure to increases in fuel  prices is as a result of potential increased freight
costs caused by fuel surcharges or other fuel cost-driven price increases implemented  by  the third-party
package delivery companies on which we rely. We estimate that our annual freight costs (which consists
of in-bound and out-bound freight-related costs, net of  freight revenue) during  the years ended
September 30, 2015 and 2014 was $23.6 million and $18.1 million, respectively, and as a result, we do
not believe the impact of these potential fuel surcharges or fuel cost-driven price increases would have
a material impact on our business, financial condition and results of operations. In addition, increases
in fuel prices may have an indirect material adverse effect on our business, financial condition and
results of operations, as such increases may contribute to decreased airline profitability and, as a result,
decreased demand for new commercial aircraft that  utilize the products we sell. See Part I, Item  1A.
‘‘Risk Factors—We may be materially adversely affected by high fuel prices.’’ We do not use derivatives
to manage our exposure to fuel prices.

In our opinion, the accompanying consolidated balance sheets and the related consolidated
statements of comprehensive income, stockholders’  equity and cash flows present fairly, in  all material
respects, the financial position of Wesco Aircraft Holdings, Inc. and its subsidiaries at September 30,
2015 and September 30, 2014, and the results of their operations and their cash flows for each of the
three years in the  period ended September 30, 2015 in conformity with  accounting principles generally
accepted in the United States of America. Also  in our opinion, the Company did not maintain, in all
material respects, effective internal control over financial reporting as  of September 30, 2015, based  on
criteria established in Internal Control—Integrated Framework (2013) issued by the Committee of
Sponsoring Organizations of the Treadway Commission (COSO)  because  material weaknesses in
internal control over financial reporting existed as of that date. One material weakness relates to a lack
of a sufficient complement of accounting and financial  reporting personnel with an appropriate  level of
accounting knowledge and experience commensurate with the Company’s financial reporting
requirements. This material weakness contributed to additional  material weaknesses as: 1) the
Company did not maintain effective controls over account reconciliations and 2) the Company did not
maintain controls over the integration of  policies, practices and controls over the Haas business  unit. A
material weakness is a deficiency, or a combination of deficiencies,  in internal control over financial
reporting, such that there is a reasonable possibility that a  material misstatement of the annual or
interim financial statements will not be prevented  or detected  on a timely  basis. The material
weaknesses referred to above are described  in Management’s Report on  Internal Control over Financial
Reporting appearing under Item 9A. We considered these material weaknesses in determining the
nature, timing, and extent of audit tests applied in our audit of the  September 30, 2015  consolidated
financial statements, and our opinion regarding the effectiveness of the Company’s internal control over
financial reporting does not affect our opinion on those consolidated financial statements. The
Company’s management is responsible for these financial statements, for maintaining effective internal
control over financial reporting and for its assessment of the effectiveness of internal control over
financial reporting included in management’s report referred to above. Our responsibility is to express
opinions on these financial statements and on the  Company’s internal control over financial reporting
based on our integrated 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 audits to obtain reasonable assurance about whether the financial statements are free of
material misstatement and whether effective  internal control over financial reporting was maintained in
all material respects. Our audits of the financial statements included examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,  assessing the accounting
principles used and significant estimates made by management, and evaluating  the overall financial
statement presentation. Our audit of internal control over  financial reporting included  obtaining an
understanding of internal control over  financial reporting, assessing the risk that a  material weakness
exists, and testing and evaluating the design and operating effectiveness  of internal control based on
the assessed risk. Our audits also included performing  such other procedures as we considered
necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

A company’s internal control over financial reporting is a process designed 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 (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 preparation of financial statements in accordance with generally

Wesco Aircraft Holdings, Inc. & Subsidiaries

Notes to the Consolidated Financial Statements

Note 1. Organization and Business

Our company, Wesco Aircraft Holdings,  Inc., is a distributor and provider of  comprehensive supply

chain management services to the global aerospace industry. Our  services range from traditional
distribution to the management of supplier relationships, quality  assurance, kitting, just-in-time (JIT)
delivery, and point-of-use inventory management.

In addition to the central stocking facilities, we use a  network of  forward-stocking locations to
service its customers in a JIT and or ad hoc manner. There are  over 60 stocking locations  around the
world with concentrations in North America and  Europe.  In  addition to product fulfillment, we also
provide comprehensive supply chain  management services for selected customers. These services
include procurement and JIT inventory management and delivery  services.

On February 28, 2014, we acquired 100% of the outstanding stock of Haas. The acquired assets

and liabilities assumed have been recorded at fair value for the interests acquired.

Note 2. Basis of Presentation and Summary of  Significant Accounting Policies

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of Wesco Aircraft
Hardware, Wesco Aircraft Europe, Flintbrook Limited, Wesco  Aircraft Germany GmbH, Wesco
Aircraft France SAS, Wesco Aircraft Israel Limited, Wesco  Aircraft Italy SRL, Wesco Aircraft
Hardware India Pvt., Limited, Wesco Aircraft Trading Shanghai Co., Limited, Interfast  Europe Limited,
Interfast USA Inc., Interfast USA Holdings Inc. and  Haas. All intercompany accounts and transactions
have been eliminated. When we do not have a controlling interest  in an entity,  but exert significant
influence over the entity, we apply the equity method of  accounting.

Use of Estimates in Preparation of Financial Statements

The preparation of financial statements,  in conformity with accounting principles generally
accepted in the United States of America, requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities and the 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. Estimates are used for,  but not limited to, receivable valuations and
allowance for sales returns, inventory  valuations of excess and obsolescence (E&O) inventories, the
useful lives of long-lived assets including  property,  equipment and intangible assets, annual goodwill
impairment assessment, stock-based compensation, income taxes and contingencies. Actual results  could
differ from such estimates.

Revision of Consolidated Statements of Stockholders’ Equity

On September 28, 2012, we were scheduled to deliver 5,604,338 shares  of our common stock to
certain employees and former employees in satisfaction  of the terms of restricted stock unit  awards
(RSU’s) that had been granted in connection with our Company’s recapitalization with The  Carlyle
Group in 2006. We elected to pay $8,452,000 in  cash, in lieu of  the  delivery of 626,225 shares, pursuant
to the terms of the applicable equity incentive plan. The $8,452,000 was remitted to satisfy a portion of
the RSU holders’ minimum tax withholding liabilities on October 3, 2012  and recorded as our treasury
stock, which reduced our stockholders’ equity balance.

Note 2. Basis of Presentation and Summary of  Significant Accounting Policies (Continued)

In connection with this transaction, we  reported an addition to our shareholders’  common stock

shares of 5,604,338 for the year ended  September 30, 2012,  resulting in an  overstatement  of  our
common stock by 626,225 shares, an understatement  of our current liability  and an  overstatement of
our  additional paid in capital (APIC)  by  $8,452,000, and an overstatement of our total stockholders’
equity by $8,452,000 in our consolidated  balance  sheet  and  consolidated statement of stockholders’
equity as of September 30, 2012. This error had no effect on our  consolidated total assets and
consolidated total liabilities and stockholders’ equity as of September 30, 2012,  and no effect on  our
consolidated statements of comprehensive  income and consolidated statement of cash flow for  the year
ended September 30, 2012.

After remitting the $8,452,000 to satisfy  the RSU holders’ minimum tax withholding liabilities on

October 3, 2012, we recorded the $8,452,000  as our treasury  stock, which reduced our total
stockholders’ equity by such amount in our  consolidated  balance sheet  and  consolidated  statement  of
stockholders’ equity as of September 30,  2013. As a  result, our total stockholders’ equity was  correctly
stated with an overstated APIC offset  by  an overstated treasury  stock.

We  have revised the balance of our consolidated statement of equity as  of September  30, 2012 and
reduced our treasury stock to zero. The treasury stock  transaction was  eliminated to correctly state the
shareholders’ equity as of September  30, 2013, which  was  rolled forward to  correctly present our
consolidated statement of equity as of  September 30,  2014.

Revision of Statements of Comprehensive  Income

In the three months ended September  30, 2015, we determined that  certain  personnel costs
incurred pursuant to certain service contracts were  charged  to  selling,  general and administrative
expenses rather than to cost of sales.  We  have revised our statements of comprehensive income to
properly state such selling, general and administrative expenses as cost of sales. We misclassified
expenses of $15,432,000, and $4,651,000 for  the years ended September  30, 2014 and 2013,  respectively.
The expenses misclassified for North America were $14,046,000, and  $3,637,000 for  the years ended
September 30, 2014 and 2013, respectively.  The  expenses misclassified for Rest of World were
$1,386,000, and $1,014,000 for the years ended  September 30, 2014  and 2013, respectively.  These
misclassifications had no effect on previously  reported income  from operations, net income or  cash
flows for the years ended September 30,  2014 and 2013 and the interim  periods  within those  years.  We
have evaluated these misclassifications  and  do  not  believe they are material to any prior periods.

Cash and Cash Equivalents

We  consider all highly liquid investments with  original maturities from  date of purchase of three

months or less to be cash equivalents.

Accounts Receivable

Accounts receivable consist of amounts owed to us by customers. We  perform periodic  credit

evaluations of the financial condition of  our customers,  monitor collections  and payments from
customers, and generally do not require collateral. Accounts receivable are generally  due  within 30 to
60 days. We provide for the possible inability to collect accounts  receivable by recording an allowance
for doubtful accounts. We reserve for an  account  when it is considered to be uncollectible. We estimate
our  allowance for doubtful accounts based on historical experience, aging of accounts receivable and

information regarding the creditworthiness of our customers. To date, losses have  been within  the range
of management’s expectations. If the  estimated allowance for doubtful  accounts subsequently proves to
be insufficient, additional allowances may be required.

Our allowance for doubtful accounts activity consists  of the following (in thousands):

Inventories

Inventories are stated at the lower of cost or market. The  method by which  amounts  are removed

from inventory are weighted average cost  for all inventory, except  for chemical parts for which the
first-in, first-out method is used. In-bound freight-related costs of $1,662,000, $1,440,000  and $0 as of
September 30, 2015, 2014, and 2013, respectively, are included as part of the cost of inventory held  for
resale. We record provisions, as appropriate, to write-down  E&O inventory to estimated net  realizable
value. The process for evaluating E&O inventory utilizes  factors such as historical demand and current
inventory quantities, and subjective judgments and estimates concerning future sales levels, quantities
and prices at which such inventories will be able to be sold in the normal course of business. During
the year ended September 30, 2015, we charged $33,000,000 and $62,052,000 to cost of sales for
impairment of inventory to net realizable value and  for increases in  our E&O reserve and related
items, respectively, as further described below.

In the fourth quarter of 2015, we determined that  inventory previously purchased in connection
with a specific program which was subsequently terminated, to have no alternative use. During the year
ended September 30, 2015, we continued to negotiate a sale of such inventory with our customer for
whom such inventory was purchased, as well  as market the inventory through other channels, and
believed the full cost of this inventory was recoverable. However, in the fourth quarter of 2015, we
determined such inventory was not marketable and recorded a reduction in net realizable value of
$33,000,000.

In the fourth quarter of 2015, management implemented a new strategy of providing integrated

supply chain services more tailored to customer demand through long-term contracts and  focused
forecasted consumption including changes to our inventory purchasing strategy, holding inventory for
shorter periods and the planned scrapping of long dated inventory.  The new strategy and updates for
fiscal 2015 sales activities led to changes in the sell through rates, holding period  of aged inventory and
others estimates used in the E&O reserve  for our hardware inventory, which increased our E&O
inventory reserves by $43,800,000.

Property and Equipment

Property and equipment are stated at cost, less accumulated amortization and depreciation,
computed using the straight-line method over  the estimated useful life of each asset. Leasehold
improvements are  amortized over the lesser of the remaining lease term or  the estimated useful  life of

the assets. Expenditures for repair and  maintenance costs are expensed as  incurred, and expenditures
for major renewals and improvements  are  capitalized. When assets are  retired or otherwise disposed of,
the cost and accumulated depreciation and amortization are removed from  the accounts and any  gain

Impairment of Long-Lived Assets

We  assess potential impairments of our long-lived assets whenever events or  changes in

circumstances indicate that the carrying value  of the assets  may not be recoverable. Factors we  consider
include, but are not limited to: significant  underperformance relative to expected  historical  or projected
future operating results; significant changes in the  manner of use  of  the acquired  assets or the  strategy
for the overall business; and significant  negative industry or economic  trends. We  have determined that
our  asset group for impairment testing  is comprised of the  assets and  liabilities of each of our reporting
units, which consists of North America Hardware, Rest of  World  Hardware, North America Chemical
and Rest of World Chemical, as this is the  lowest level of identifiable  cash flows. We have identified
customer relationships as the primary asset because it is the principal asset from  which the reporting
units derive their cash flow generating  capacity and has  the longest  remaining useful life. Recoverability
is assessed by comparing the carrying value of  the asset group to the undiscounted cash flows  expected
to be generated by these assets. Impairment losses are measured as  the amount by which the  carrying
values of the primary assets exceed their  fair values.  To  date, we have not recognized an impairment
charge  related to the write-down of long-lived assets.

Deferred Financing Costs

Deferred financing costs are amortized using the effective  interest  method over the  term of the

related credit arrangement; such amortization  is included in interest expense  in the consolidated
statements of comprehensive income.  Amortization of deferred financing costs was $4,354,000,
$3,300,000 and $7,788,000 for the years ended  September 30, 2015,  2014 and 2013, respectively. As  of
September 30, 2015 and 2014, the remaining unamortized deferred financing costs are $11,248,000  and
$15,602,000, respectively.

Goodwill and Indefinite-Lived Intangible  Assets

Goodwill, which represents the excess of the consideration paid over  the fair  value of the  net
assets acquired in a business combination,  and  other  acquired intangible assets with indefinite  lives are
not amortized, but are tested for impairment at least annually or  more frequently  when an event  occurs
or circumstances change such that it  is  more likely than not that the carrying amount may be impaired.
Such events or circumstances may be a significant  change in business climate, economic  and industry
trends,  legal factors, negative operating  performance indicators, significant competition,  changes in
strategy, or disposition of a reporting unit or a portion thereof.  Goodwill and indefinite-lived

intangibles asset impairment testing is  performed at the  reporting unit level on  July 1 of each year. Our
reporting units are one level below our operating segments.

We test goodwill for impairment by performing a qualitative process, or  a two-step quantitative

assessment process. The first step of the quantitative process involves  comparing the carrying value of
net assets, including goodwill, to the fair value of the reporting unit. If the fair value exceeds its
carrying amount, goodwill is not considered impaired and the second step of the process is unnecessary.
If the carrying amount of a reporting unit’s goodwill exceeds its  fair value, the second step measures
the impairment loss, if any.

The second step compares the implied fair  value  of  goodwill with the carrying amount of that

goodwill. The implied fair value of goodwill is determined in the  same  manner  as the amount of
goodwill recognized in a business combination. The implied fair value of the reporting unit’s goodwill is
calculated by creating a hypothetical balance sheet  as if the reporting unit had just been  acquired. This
balance sheet contains all assets and liabilities recorded at fair value  (including any intangible assets
that may not have any corresponding carrying value  in our balance sheet).  The implied value of the
reporting unit’s goodwill is calculated by subtracting the fair value of the net  assets from the fair value
of the reporting unit. If the carrying  value of goodwill exceeds  the implied fair value of  that goodwill,
an impairment loss is recognized in an amount equal to that excess. We performed our goodwill
impairment tests for the years ended September 30, 2015, 2014  and 2013, which resulted in a goodwill
impairment charge of $263,771,000 in the year ended September 30, 2015 for our North America
Hardware reporting unit. Refer to Note 8 for additional information.

Indefinite-lived intangibles consist of a trademark, for which we estimate fair value and compare
such fair value to the carrying amount. If the carrying  amount of the trademark exceeds its fair value,
an impairment loss is recognized in an amount equal to that excess.

Fair Value of Financial Instruments

Fair value is the price that would be received to sell an asset or paid to transfer a liability in an

orderly transaction between market participants  at the measurement date.  To  determine  fair value, we
primarily  utilize reported market transactions and discounted cash flow analyses. We use  a three tier
fair value hierarchy that maximizes the use of observable inputs and  minimizes the use of unobservable
inputs. 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 sources independent of us.
Unobservable inputs are inputs that reflect our own  assumptions about the assumptions market
participants would use in pricing the asset or liability developed  based on the best information available
in the circumstances. The fair value hierarchy prioritizes the  inputs to valuation techniques into three
broad levels whereby the highest priority is given to Level 1 inputs  and the lowest to Level 3 inputs.
The three broad categories are:

Level 1: Quoted prices in active markets for identical assets or liabilities.

Level 2:

Inputs other than quoted prices that are observable for the asset or liability, either directly or
indirectly.

Level 3: Unobservable inputs for the asset or liability.

Note 2. Basis of Presentation and Summary of  Significant Accounting Policies (Continued)

The definition of fair value includes the  consideration of nonperformance risk. Nonperformance

risk refers to the risk that an obligation  (either  by  a counterparty or us) will not be fulfilled.  For
financial assets traded in an active market  (Level  1),the  nonperformance  risk is included  in the market
price. For certain other financial assets  and  liabilities (Level  2 and  3), our fair value calculations have
been adjusted accordingly.

Fair value measurements are classified according to the  lowest level input or  value-driver that is

significant to the valuation. A measurement  may  therefore be classified within Level 3 even though
there may be significant inputs that are  readily observable.

We  use observable market-based inputs to calculate fair value of our  interest rate  swap agreements

and outstanding debt instruments, in  which case  the measurements  are  classified within  Level  2. If
quoted or observable market prices are not available, fair value  is based upon internally developed
models  that use, where possible, current market-based parameters such  as interest rates, yield  curves
and currency rates. These measurements are classified within Level 3.

Where available, we utilize quoted market  prices or observable inputs rather  than unobservable

inputs to determine fair value.

Derivative Financial Instruments

We  periodically enter into cash flow derivative transactions, such as  interest rate swap agreements,

to hedge exposure to various risks related  to interest rates. We recognize  all  derivatives at their fair
value as either assets or liabilities. For  cash flow designated  hedges, the  effective portion of the  changes
in fair value of the derivative contract  are  recorded in  accumulated  other  comprehensive income (loss),
net of taxes, and are recognized in net earnings at  the time earnings are affected by the hedged
transaction. Adjustments to record changes in fair values of the derivative contracts that are
attributable to the ineffective portion  of  the hedges, if any, are recognized in  earnings. We present
derivative instruments in our consolidated statements  of  cash flows’  operating, investing, or financing
activities consistent with the cash flows of  the hedged item.

Comprehensive Loss or Income

Comprehensive loss or income generally  represents all changes  in stockholders’ equity, except
those resulting from investments by or distributions to stockholders. Our comprehensive loss  or income
consists of foreign currency translation adjustments and  fair value adjustments for cash flow  hedges.

Revenue Recognition

We  recognize product and service revenue  when (1) persuasive evidence of an arrangement  exists,

(2) title transfers to the customer, (3) the  sales price charged is fixed or determinable, and
(4) collection is reasonably assured. In instances where  title does not  pass  to  the customer  upon
shipment, we recognize revenue upon delivery  or customer acceptance, depending  on the  terms of the
sales contract.

In connection with the sales of our products,  we often  provide certain supply chain management

services to our JIT customers. These services include the  timely  replenishment of  products at the
customer site, while also minimizing  the  customer’s on-hand inventory. We  provide these  services
contemporaneously with the delivery  of  the product, and as such, once the  product is delivered,  we do

not have a post-delivery obligation to provide services to the customer. Accordingly, the price of such
services is generally included in the price of the  products delivered to the customer, and revenue is
recognized upon delivery of the product, at which point we have satisfied our obligations to the
customer. We do not account for these  services as a separate element, as the services do not have
stand-alone value and cannot be separated from  the product element of the arrangement.  Additionally,
we do not present service revenues apart from product revenues, as the  service  revenues represent less
than 10% of our consolidated net sales.

We report revenue on a gross or net basis,  based on management’s assessment of whether we act
as a principal or agent in the transaction, in our presentation of net sales and costs of sales. If we  are
the principal in the transaction and have the  risks and rewards of ownership, the transactions are
recorded as gross in the consolidated statements  of  comprehensive income. If we do not act as a
principal in the transaction, the transactions are recorded on a net basis in  the consolidated statements
of comprehensive income. The majority of our revenue is recorded  on a gross basis with the exception
of certain gas, energy and chemical manager service contracts that are recorded as net revenue.

We also enter into sales rebates and profit sharing arrangements. Such customer incentives are
accounted for as a reduction to gross sales and recorded  based upon estimates at the time products are
sold. These estimates are based upon historical experience for similar programs and  products. We
review such rebates and profit sharing arrangements on an ongoing basis and accruals are adjusted, if
necessary, as additional information becomes available.

We provide allowances for credits and returns based on historic experience and adjust such
allowances as considered necessary. To date, such provisions have been within the range of our
expectations and the allowance established. Sales tax collected from customers is  excluded from net
sales in the consolidated statements of comprehensive income.

In connection with our JIT supply chain management programs,  at times, we  assume customer
inventory on a consignment basis. This consigned inventory remains the  property of the customer but is
managed and distributed by us. We earn a fixed fee per unit  on each shipment of the consigned
inventory; such amounts represent less than 1% of consolidated net sales.

Shipping and Handling Costs

We record revenue for shipping and handling billed to our customers. Shipping  and handling
revenues were $7,825,000, $6,951,000 and $1,304,000 for the years ended  September 30, 2015, 2014 and
2013, respectively.

Shipping and handling costs are primarily included in cost of sales. Total shipping and handling

costs were $33,173,000, $24,801,000 and  $8,330,000 for  the years ended September 30, 2015, 2014 and
2013, respectively.

Income Taxes

We recognize deferred tax liabilities and assets for the expected future  tax consequences of

temporary differences between the carrying amounts and the tax bases of assets and liabilities. Deferred
income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable
income in the years in which these temporary differences are expected to be recovered or settled. 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.  A valuation allowance is established, when necessary, to
reduce net deferred tax assets to the  amount  expected to be realized. The ultimate realization of
deferred tax assets depends upon the generation of future taxable income during the periods in  which
temporary differences become deductible  or includible in  taxable income. We consider projected future
taxable income and tax planning strategies in our assessment.  Our foreign subsidiaries are taxed in local
jurisdictions at local statutory rates.

Concentration of Credit Risk and Significant Vendors and Customers

We  maintain our cash and cash equivalents in  bank deposit accounts which, at times, may exceed

federally insured limits. We have not  experienced  any losses in such accounts  and do  not  believe we  are
exposed  to any significant credit risk  from  cash  and cash equivalents.

We  purchase our products on credit  terms  from vendors  located  throughout  North America  and

Europe. For the years ended September 30,  2015, 2014 and 2013,  we made 13%, 15%,  and 20%,
respectively, of our purchases from Precision Castparts Corp. and the amounts  payable to this vendor
were 7% and 6% of total accounts payable at September 30, 2015 and 2014, respectively. Additionally,
for the years ended September 30, 2015,  2014  and 2013,  we made 9%, 15%, and  19%, respectively,  of
our  purchases from Alcoa Fastening  Systems and the amounts payable  to this vendor  were 6%  and
10% of total accounts payable at September 30,  2015 and 2014, respectively. The majority of  the
products we sell are available through multiple channels and, therefore, this reduces the risk related to
any vendor relationship.

For the years ended September 30, 2015, 2014  and  2013, we  did not derive 10% or more  of our

total net sales from any individual customer. Government sales, which were derived from  various
military parts procurement agencies such  as  the U.S.  Defense  Logistics Agency,  or from defense
contractors buying on their behalf, comprised  14%, 9% and 2% of our net  sales  during  fiscal 2015,
2014 and 2013, respectively.

the Black-Scholes option pricing model. The Black-Scholes  option pricing model considers, among
other factors, the expected life of the award and the expected volatility of our stock price. We
recognize the stock-based compensation expense over the  requisite service  period (generally a vesting
term of three years) using the graded vesting method  for performance condition awards and the
straight line method for service condition only awards, which  is generally a vesting term of three years.
Stock options typically have a contractual term of 10 years. The stock options granted have an exercise
price equal to the closing stock price of our common stock on the grant  date. Compensation expense
for restricted stock units and awards are based on the market price of the shares underlying the awards
on the grant date. Compensation expense for performance based awards reflects the estimated
probability that the performance condition will be met.

Net Loss or Net Income Per Share

Basic net loss or net income per share  is computed  by dividing net loss or net income available to

common stockholders by the weighted average  number of common shares outstanding during the
period. Diluted net loss or net income per share includes the dilutive effect of  both outstanding stock
options and restricted shares, calculated using the treasury stock method. Assumed proceeds from the
in-the-money options include the tax benefits, net of shortfalls, calculated under the ‘‘as-if’’ method.

Note 3. Recent Accounting Pronouncements

Changes to generally accepted accounting principles  in the United States (GAAP) are established

by the Financial Accounting Standards Board (FASB), in the form of Accounting Standards  Updates
(ASUs), to the FASB’s Accounting Standards Codification.

We consider the applicability and impact of all ASUs. ASUs not listed below were assessed and
determined to be either not applicable or  are expected to have minimal impact on our  consolidated
financial position and results of operations.

Foreign Currency Translation and Transactions

New Accounting Standards Updates

The financial statements of foreign subsidiaries and affiliates where  the  local currency is the
functional currency are translated into  U.S.  Dollars using exchange rates in effect  at each period-end
for assets and liabilities and average  exchange rates  during the period  for  results of operations. The
adjustment resulting from translating the financial statements of such foreign  subsidiaries  is reflected as
a separate component of stockholders’  equity. Foreign currency transaction gains and losses are
reported as other income (expense), net  in the consolidated statements of comprehensive income. For
the years ended September 30, 2015, 2014  and  2013, realized foreign currency transaction  gains were
$614,000, $1,555,000 and $1,748,000, respectively.

Stock-Based Compensation

We  recognize all stock-based awards to employees and directors  as stock-based  compensation

expense based upon their fair values  on the  date of  grant.

We  estimate the fair value of stock-based payment awards on the date  of grant. The value of the

portion of the award that is ultimately  expected to vest  is recognized as an expense during the requisite
service periods. We have estimated the  fair  value for  each  option award as of the date of grant using

In September 2015, FASB issued ASU No. 2015-16, Business Combinations (Topic 805): Simplifying

the Accounting for Measurement-Period Adjustments. ASU 2015-16 requires that an acquirer  recognize
adjustments to provisional amounts that are identified during the measurement period in the reporting
period in which the adjustment amounts are determined. ASU 2015-16  is effective for fiscal years
beginning after December 15, 2015, including interim periods  within those fiscal years. ASU 2015-16
should  be applied prospectively to adjustments to provisional amounts that occur after the effective
date of this update with earlier application permitted for financial statements that have not been
issued. We are currently evaluating the impact of the adoption of ASU 2015-16 on our financial
statements and disclosures.

In August 2015, the FASB issued ASU 2015-15, Interest—Imputation of Interest: Presentation and

Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements.
ASU 2015-15 states entities should present debt issuance costs  as an asset,  and subsequently amortize
the deferred debt issuance costs ratably over the term  of the line-of-credit  arrangement, regardless of
whether there are any outstanding borrowings on the line-of-credit arrangement. We are currently
evaluating the impact of the adoption of ASU 2015-15 on our financial statements and  disclosures.

In July 2015, the FASB issued ASU 2015-11, Simplifying the Measurement of Inventory, which
requires an entity to measure inventory at  the lower of  cost and net realizable value, and eliminates
current GAAP options for measuring  market  value. ASU  2015-11 defines realizable  value as  the
estimated selling prices in the ordinary course of business, less reasonably predictable costs  of
completion, disposal, and transportation.  ASU 2015-11  is effective for annual reporting periods
beginning after December 15, 2016, and interim periods  within those fiscal years. Early adoption is
permitted for financial statements that have not been previously issued.  ASU 2015-11 can only be
applied  prospectively. We are currently evaluating the impact of the  adoption of ASU 2015-11 on  our
financial statements and disclosures.

In April 2015, the FASB issued ASU 2015-05, Intangibles—Goodwill and Other—Internal-Use

Software  (Subtopic 350-40): Customer’s Accounting for  Fees Paid in a Cloud Computing  Arrangement.
ASU 2015-05 provides explicit guidance  to  help  companies evaluate the accounting for fees paid by a
customer in a cloud computing arrangement. The new guidance clarifies that if  a cloud computing
arrangement includes a software license, the customer should account for  the license  consistent with  its
accounting for other software licenses. If the arrangement  does not include  a software license, the
customer should account for the arrangement as a  service contract.  ASU 2015-05 is  effective  for public
business entities for annual periods, including interim periods within  those annual periods, beginning
after December 15, 2015. An entity can elect to adopt  the amendments either prospectively for all
arrangements entered into or materially modified after the effective  date, or retrospectively. Early
adoption is permitted. We are currently  evaluating the impact of the  adoption  of ASU  2015-05 on our
financial statements and disclosures.

In April 2015, the FASB issued ASU 2015-03, Interest—Imputation of Interest (Subtopic 835-30):
Simplifying the Presentation of Debt Issuance Cost. The amendments in ASU 2015-03 are  intended to
simplify the presentation of debt issuance costs. These amendments require 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. The recognition  and measurement
guidance for debt issuance costs are not  affected by the  amendments in ASU 2015-03.  ASU 2105-03 is
effective for annual reporting periods  beginning  after December 15, 2015,  and interim  periods  within
those fiscal years. Early adoption is permitted  for financial statements that  have not been previously
issued. We are currently evaluating the impact of the adoption of ASU 2015-03  on our financial
statements and disclosures.

In August 2014, the FASB issued ASU 2014-15, Disclosure of Uncertainties about an Entity’s Ability

to Continue as a Going Concern, which amends ASC Subtopic 205-40  to  provide  guidance about
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 disclosures. Specifically,  ASU 2014-15 (1)  provides a
definition of the term ‘‘substantial doubt,’’ (2) requires an  evaluation every reporting period,
(3) provides principles for considering  the mitigating effect of  management’s plans, (4) requires certain
disclosures when substantial doubt is  alleviated as  a result  of consideration of management’s plans,
(5) requires an express statement and  other  disclosures when substantial doubt is not alleviated,  and
(6) requires an assessment for a period of  one  year after the date that financial statements are issued.
ASU 2014-15 is effective for fiscal years  ending after  December 15,  2016, and for  annual periods and
interim periods thereafter. We do not  anticipate the  adoption  of  ASU 2014-15 will have a  significant
impact on our consolidated financial  statements.

In June 2014, the FASB issued ASU 2014-12, Compensation—Stock Compensation (Topic 718):
Accounting for Share-Based Payments  when the Terms of an Award Provide that a Performance Target
Could Be Achieved After the Requisite Service Period. ASU 2014-12 requires that a performance target
that affects vesting and that could be achieved after the  requisite service  period be treated  as a
performance condition. ASU 2014-12 is effective for annual periods and interim periods within those
annual periods beginning after December 15, 2015. Earlier adoption is permitted. Entities may apply
ASU 2014-12 either prospectively to all awards granted or modified after  the effective date or
retrospectively to all awards with performance targets  that are outstanding as of the beginning of the
earliest  annual period presented in the financial statements and to all new or modified awards
thereafter. If retrospective transition is adopted,  the cumulative effect of applying  this ASU as of the
beginning of the earliest annual period presented  in the financial statements should be recognized as  an
adjustment to the opening retained earnings balance at that date. Additionally, if retrospective
transition is adopted, an entity may use hindsight  in measuring and  recognizing the compensation cost.
We are currently evaluating the impact  of the adoption of ASU 2014-12 on our financial statements
and disclosures.

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606).
ASU 2014-09 provides comprehensive guidance on the recognition of revenue from customers arising
from the transfer of goods and services. ASU 2014-09 also provides guidance on accounting for certain
contract costs, and requires new disclosures. In August  2015, the FASB issued ASU 2015-14, Revenue
from Contracts with Customers (Topic 606): Deferral of the Effective Date, which deferred the effective
date of ASU 2014-09 for all entities by  one year. Accordingly, ASU 2014-09 is  effective  for annual
reporting periods beginning after December 15, 2017,  including interim reporting periods within that
reporting period. Early adoption is permitted for annual reporting periods  beginning  after
December 15, 2016, including interim reporting  periods within that reporting period. We are  currently
evaluating the effect of the adoption of ASU 2014-09 on our consolidated financial statements and the
implementation approach to be used.

Adopted Accounting Standards Updates

Effective July 1, 2015, we adopted ASU 2014-08, Presentation of Financial Statements and Property,

Plant, and Equipment, which addresses revised guidance on reporting discontinued operations. This
revised guidance defines a discontinued operation as a disposal of a component or a group  of
components of an entity that represents a strategic shift that has  (or will have)  a major effect on the
entity’s operations and financial results. ASU 2014-08  also requires additional disclosures for
discontinued operations and new disclosures for individually material disposal transactions that do  not
meet the definition of a discontinued operation.  Our adoption of ASU 2014-08 did not have a material
impact on our consolidated financial statements.

Effective November 18, 2014, we adopted ASU 2014-17, Business Combinations (Topic 805):
Pushdown Accounting. ASU 2014-17 provides an acquired entity  with the  option to apply pushdown
accounting in its separate financial statements upon occurrence  of an event in  which an acquirer
obtains control of the acquired entity. The  election to apply pushdown accounting can be made either
in the period in which the change of control occurred, or in a subsequent period. Our adoption of
ASU 2014-08 did not have a material impact on  our consolidated financial statements.

Note 4. Acquisitions

2014 Acquisition

On February 28, 2014, through our wholly owned subsidiary, Flyer Acquisition  Corp., we  acquired

100% of the outstanding shares of Haas,  for a  purchase  price of $560,450,000,  including the  payment of
an additional $250,000 in the three months ended December 31, 2014 as  a result  of  a working  capital
adjustment.

The Haas acquisition was financed through a  combination  of  a new  $525,000,000 term  loan B

facility, cash on hand and drawings under our revolving facility. As  a result of  the acquisition, Haas
became our wholly-owned subsidiary. We incurred transaction related costs  of $6,700,000 and such costs
were expensed as incurred.

Haas is a provider of chemical supply chain management  services  to  the commercial aerospace,

airline, military, energy, and other markets,  helping its customers reduce costs and  comply with
increasingly complex regulatory requirements  for chemical  usage. The Haas acquisition expands our
existing customer base and active stock-keeping units, while also providing us with  opportunities to
increase sales by leveraging and cross-selling into Wesco’s  and Haas’ respective customer bases. In
addition, we believe the addition of Haas’  proprietary information technology system (tcmIS), which
interfaces directly with customer and  supplier enterprise resource  planning systems,  and its experienced
senior management team, will benefit  Wesco going forward.

The goodwill related to the Haas acquisition represents the  value paid for assembled workforce, its

international geographic presence and  synergies expected to arise after the acquisition. None  of  the
goodwill resulting from the Haas acquisition is deductible for income tax purposes.  On the date of
acquisition, the goodwill was allocated  to  our  reporting units based on  the proportion  of  cash flows
generated in the North America and the Rest of World segments.

We  revised the purchase price allocation during the three  months ended  December 31,  2014 to
reflect a  $250,000 payment to Haas’ former owners as a  result of a working capital  adjustment.  This
adjustment resulted in an increase to goodwill of $250,000. The preliminary fair  values  of  assets
acquired and liabilities assumed on the acquisition date and the  final  allocations  were as follows (in
thousands):

The excess purchase price over the fair value of  the net identifiable assets acquired was recorded

income approach method using assumptions and estimates derived by our management. It was
determined that the Haas trademark has a  15-year estimated useful life, customer relationships  have a
15-year estimated useful life and Haas’  technology has a  10-year estimated useful life. Factors
considered in the determination of its useful  lives include customer attrition rates, technology life
cycles, and patent and trademark laws.

The results of Haas since the acquisition have been  included in  the consolidated financial

statements and are included in the North America and Rest of World segments  based on actual results
of the reporting units.

Haas consolidated net sales included in the financial  statements since the acquisition date were
$591,824,000 and $356,154,000 in the years ended September 30, 2015 and 2014, respectively. Haas
consolidated net loss or income included in the financial statements  since  the acquisition date was a net
loss of $565,000 and a net income of $2,850,000 in the years ended  September 30, 2015 and  2014,
respectively.

Pro Forma Consolidated Results

The following pro forma information presents the financial  results as if the acquisition of  Haas had
occurred on October 1, 2012. The pro forma results do not include any anticipated cost synergies, costs
or other effects of the planned integration of the acquisition. Accordingly, such  pro forma amounts are
not necessarily indicative of the results that actually would have occurred had the acquisitions been
completed on the dates indicated, nor are they indicative of future  operating results. We did not have
any material, nonrecurring pro forma  adjustments directly attributable to the business combination in
the reported pro-forma net sales and earnings (in thousands except  per  share data).

Note 5. Inventory

Our inventory is comprised solely of finished goods.

As of September 30, 2015 and 2014, our E&O reserve was $264,114,000 and $197,188,000,
respectively. We have revised the previously reported E&O reserve  as of September 30, 2014 of
$143,736,000 that was not correct due to a clerical error in  the prior  year footnote. This immaterial
revision does not change the inventory  amount reported on  the balance sheet or the amount of E&O
charges recorded in the statement of comprehensive income.  Charges to cost of sales for increase in
our E&O reserves and related items were $95,052,000, $17,700,000  and $8,710,000 in the years ended
September 30, 2015, 2014 and 2013, respectively. We believe that these  amounts appropriately reflect
the risk of E&O inventory inherent in our  business.

In the fourth quarter of 2015, management implemented a new  strategy of providing  integrated

supply chain services more tailored to  customer demand through long-term contracts and  focused
forecasted consumption including changes  to our inventory purchasing  strategy, holding inventory  for
shorter periods and the planned scrapping of long dated inventory.  The  new strategy and updates  for
fiscal 2015 sales activities led to changes  in the  sell through rates, holding period  of  aged inventory and
others estimates used in the E&O reserve  for our hardware inventory, which  increased  our E&O
inventory reserves by $43,800,000.

Note 6. Related Party Transactions

We  entered into a management agreement  with The Carlyle Group to provide certain financial,
strategic advisory and consultancy services.  Under  this  management agreement, we are obligated to pay
The Carlyle Group, or a designee thereof, an annual  management fee of $1,000,000 plus fees and
expenses associated with company-related  meetings.  We incurred expense of $1,145,000, $1,077,000 and
$1,053,000 for the years ended September 30, 2015,  2014 and 2013, respectively, related to this
management agreement. These amounts  were paid to The Carlyle Group during the years ended
September 30, 2015, 2014 and 2013.

We  lease several office and warehouse facilities under  operating lease agreements from entities
controlled by our former chief executive officer, who  is also our Chairman of the  Board. Rent expense
on these facilities was $1,692,000, $1,826,000 and $1,754,000 for the years ended September 30,  2015,
2014 and 2013, respectively (see Note  17).

We test goodwill for impairment using a qualitative assessment process or a two-step quantitative

assessment process. The first step of the quantitative assessment process involves  comparing the
carrying value of net assets, including  goodwill, to the fair value of the reporting unit. If  the fair value
exceeds its carrying amount, goodwill is not considered impaired and the second step of the process is
unnecessary. If the carrying amount of  a reporting unit’s goodwill exceeds its fair value, the second step
measures the impairment loss, if any.

The estimates of fair value of a reporting unit are determined based on a discounted cash flow
analysis and market earnings multiples. A  discounted cash flow analysis  requires us to make various
judgmental assumptions, including assumptions about future cash flows, growth rates and discount
rates. The assumptions about future cash  flows and growth rates are  based on the forecast and
long-term business plans of each reporting unit. Discount rate assumptions are based on an assessment
of the risk inherent in the future cash  flows of the respective reporting units. If the fair value exceeds
the carrying value of a reporting unit, goodwill is  not considered impaired and the second step of the
test is unnecessary. If the carrying amount of a reporting  unit’s goodwill exceeds the fair value of a
reporting unit, the second step measures the impairment loss, if any.

The second step compares the implied fair  value  of  goodwill with the carrying amount of that

goodwill. The implied fair value of goodwill is determined in the  same  manner  as the amount of
goodwill recognized in a business combination. If the carrying amount of  goodwill exceeds the implied
fair value of that goodwill, an impairment loss is recognized in an amount equal to that excess.

For the North America Hardware reporting unit, we performed a Step 1 goodwill impairment test

on July 1, 2012, which reflected fair value in excess of  carrying value of 38.5%. Since 2012, North
America Hardware has underperformed relative to the forecasts included in the Step 1 analysis;
however, our Step 0 impairment test  performed on July 1,  2013 and 2014 did not indicate it was more
likely than not that the carrying value exceeded the fair  value  of  the reporting unit. Through June 30,
2015, we continued to monitor North America Hardware performance relative to these forecasts.

We performed our Step 1 goodwill impairment test on July 1, 2015. The results of these tests
indicated that the estimated fair values of our reporting units exceeded their carrying values,  with the

exception of the North America Hardware reporting unit  within our North America segment. The
impact of market pressures such as decreasing  revenue and underperformance relative to forecast
adversely impacted the fair value of this reporting unit. As  a result,  we  proceeded to Step 2  of  the
goodwill impairment analysis using the most appropriate valuation methods including  the income
approach, and compared the implied value  of  North  America Hardware’s goodwill  with the carrying
value of its goodwill, and since the carrying value exceeded the implied fair  value, we recorded a
non-cash impairment charge of $263,771,000 in  the three months ended September  30, 2015.

Our financial instruments include cash and  cash equivalents, accounts receivable and payable,
accrued and other current liabilities and a revolving facility. The  carrying amounts of these instruments
approximate fair value because of their short-term maturities. The fair value  of interest rate swap
agreements is determined using pricing models that use observable market  inputs  as of the balance
sheet date, a Level 2 measurement. The fair value of the long-term  debt  instruments is determined
using current applicable rates for similar instruments as of the balance sheet  date, a Level  2
measurement.

Senior Secured Credit Facilities

Our amended credit agreement provides for (1) a $625,000,000 term loan A facility, (2) a
$200,000,000 revolving credit facility and  (3) a $525,000,000  senior secured term  loan B facility. We
refer to the term loan B facility, together with the term  loan A  facility and the  revolving facility, as the
Credit  Facilities. The Credit Facilities allowed  us  to  acquire Haas and  for Wesco Aircraft Hardware  to
incur additional first lien indebtedness and corresponding  liens  to  permit the incurrence of  the term
loan B facility and to reset certain ratios  with respect  to  the Consolidated Total Leverage Ratio
covenant applicable to the term loan A facility and the revolving facility, as  further described below.

As of September 30, 2015, our outstanding indebtedness under the Credit Facilities was

$952,906,000, which consisted of (1) $477,344,000  of  indebtedness under  the term loan  A facility and
(2) $475,562,000 of indebtedness under  the term  loan B facility.  As of September  30, 2015,
$200,000,000 was available for borrowing  under the revolving facility  without  breaching  any covenants
contained in the agreements governing  our  indebtedness.

The interest rate for the term loan A  facility is based on  the Consolidated Total Leverage Ratio

(as such ratio is defined in the Credit  Facilities) as  determined  in the  most recently delivered financial
statements, with the respective margins  ranging  from 1.75% to 2.50% for Eurocurrency loans and
0.75% to 1.50% for alternate base rate  (ABR) loans. The term loan A facility amortizes  in equal
quarterly installments of 1.25% of the  original principal amount of $625,000,000 for  the first year,
escalating to quarterly installments of 2.50% of the original principal amount of $625,000,000 by the
fifth year, with the balance due at maturity on December  7, 2017. As of September  30, 2015, the
interest rate for borrowings under the  term loan A facility  was 2.72%.

Note 11. Long-Term Debt (Continued)

The interest rate for the term loan B facility  has a  margin of 2.50% per annum for Eurocurrency

loans (subject to a minimum Eurocurrency rate  floor  of  0.75% per annum) or 1.50% per annum for
ABR loans (subject to a minimum ABR floor of 1.75% per  annum). The  term loan B  facility amortizes
in equal quarterly installments of 0.25% of the original principal amount of $525,000,000, with the
balance due at maturity on February 28,  2021. As of September 30, 2015, the interest rate for
borrowings under the term loan B facility was 3.25%.

The interest rate for the revolving facility  is based on our Consolidated Total  Leverage Ratio as

determined in the most recently delivered financial statements,  with the respective margins ranging
from 1.75% to 2.50% for Eurocurrency loans and 0.75% to 1.50% for ABR loans. The revolving facility
expires on December 7, 2017.

Under the terms and definitions applicable to the Credit Facilities as  of September 30, 2015, our
Consolidated Total Leverage Ratio (as such ratio is defined in the Credit Facilities cannot exceed 4.75
(with step-downs on such ratio during future  periods) and our Consolidated Net Interest Coverage
Ratio (as such ratio is defined in the Credit Facilities)  cannot be less than  2.25. The Credit Facilities
also contain customary negative covenants, including  restrictions on our and our restricted subsidiaries’
ability to merge and consolidate with other companies, incur indebtedness, grant liens or  security
interests on assets, make acquisitions,  loans, advances  or investments, pay dividends, sell or otherwise
transfer assets, optionally prepay or modify  terms of any junior indebtedness or enter into transactions
with affiliates. As of September 30, 2015, we were in compliance with all the foregoing covenants.  Our
borrowings under our Credit Facilities are guaranteed by us and all of our direct  and indirect, wholly-
owned, domestic restricted subsidiaries (subject to certain exceptions) and secured by a first lien on
substantially all of our assets and the assets  of our guarantor subsidiaries,  including capital stock of the
subsidiaries (in each case, subject to certain exceptions).

During the year ended September 30, 2015, we made voluntary prepayments totaling $50,000,000

on our term loan A facility and $36,313,000  on our term loan B facility, which have been  applied  to
future required quarterly payments. We also paid off our line of credit borrowing of $40,000,000.

Our subsidiary, Wesco Aircraft Europe, Ltd, has a £7,000,000 ($10,592,000 based on the

September 30, 2015 exchange rate) line of credit  that automatically  renews  annually  on October 1. The
line of credit bears interest based on the base rate plus  an applicable margin of 1.65%. There was no
outstanding borrowing under this line of credit as of September 30, 2015.

As a result of the refinancing of our old senior secured  credit facilities  on December 7, 2012, we

recorded a loss on extinguishment of debt in the amount of $4,960,000.  The  loss on early  debt
extinguishment was recorded as a component of  interest expense, net in  the consolidated statements of
comprehensive income. The refinancing costs  are being amortized over the term of the debt using the
effective interest rate method. The deferred financing costs at the close  of  the transaction on
December 7, 2012 totaled $11,168,000.

Note 12. Derivative Financial Instruments

We use derivative instruments primarily to manage exposures to interest  rates. Our primary
objective in holding derivatives is to reduce the volatility of earnings and cash flows associated with
changes in interest rates. Our derivatives expose us to credit risk to the extent that the counterparties
may be unable to meet the terms of the agreement. We, however,  seek to mitigate such  risks by

limiting our counterparties to major  financial institutions. In addition, the potential risk of loss with  any
one counterparty resulting from this type of credit  risk  is monitored. Management does not expect
material losses as a result of defaults  by  counterparties.

On July 30, 2015, we entered into interest rate  swap agreements, which we  designated as cash  flow

hedges, in order to reduce our exposure  to variability in  cash flows  related to interest payments  on a
portion of our outstanding debt. The  first  interest  rate  swap agreement  has a notional amount of
$475,000,000 giving us the contractual right to pay a fixed interest rate of 1.21%  plus the applicable
margin for term loan B (see Note 11  for  the applicable margin),  which is effective  on September  30,
2015 and matures on September 30, 2017.  The  second  interest  rate  swap agreement has a notional
amount of $375,000,000 giving us the  contractual  right to pay  a  fixed  interest  rate of 2.2625% plus the
applicable margin for term loan B, which is effective on September 29,  2017 and  matures  on
September 30, 2019.

The following table provides the location and fair value amounts  of  our hedge instruments, which
are reported in our consolidated balance  sheets as of September  30, 2015 and 2014 (in thousands). We
did not have any hedge instruments in  the year ended  September 30, 2014.

Note 15. Income Taxes (Continued)

We  are subject to U.S. federal income tax as  well as income  taxes in various state and foreign
jurisdictions. The earliest tax year still  subject to examination by a significant taxing jurisdiction is
September 30, 2011.

The undistributed earnings of our foreign subsidiaries,  which amount to $144,250,000  are

considered to be indefinitely reinvested  and no provision  for  federal or state and local  taxes or foreign
withholding taxes has been provided on  such earnings. The taxes associated  with the undistributed
earnings would be between $15,000,000  and $20,000,000.

We  determine whether it is more likely than not that a  tax  position will be sustained  upon

examination. If a tax position meets the  more-likely-than-not  recognition threshold it is then  measured
to determine the amount of benefit to recognize in the  financial statements. The tax  position  is
measured as the largest amount of benefit that  is greater than 50% likely of being realized upon
ultimate settlement. We classify gross  interest  and  penalties  and  unrecognized tax  benefits that are  not
expected to result in payment or receipt of  cash within one year as  non-current liabilities in the
consolidated balance sheets. As of September  30, 2015,  the total amount of gross  unrecognized tax
benefits was $3,072,000, including $299,000  of interest and $48,000 of penalties, all of which would
impact the effective tax rate if recognized.  It  is reasonably possible that within the next twelve months
$250,000 may be recognized as a result  of the  lapsing of the statute  of limitations.

The unrecognized tax benefits, which  exclude interest and penalties,  for  the years ended

We  determine whether it is more likely than not that some  or all of our  deferred tax  assets will not

be realized. The ultimate realization of deferred  tax assets  depends upon the generation of future
taxable income during the periods in which temporary differences become deductible or includible  in
taxable income. We consider projected future taxable income  and tax planning  strategies in our
assessment. Based upon the level of  historical income and projections for future  taxable  income,  we
believe it is more likely than not that  we will not realize the  benefits of the  temporary  differences

related to certain Haas foreign tax credits and Haas foreign net operating losses. Therefore, a valuation
allowance has been recorded against these deferred tax assets (in thousands).

Note 16. Stock-Based and Other Compensation Arrangements

On January 27, 2015, our stockholders approved the 2014 Plan, which amended and restated our

2011 Equity Incentive Award Plan and authorized the issuance of a total  of 5,717,584 shares. As of
September 30, 2015, there were 5,514,078 shares remaining available for issuance under the 2014 Plan.

Stock Options

Our stock options are eligible to vest over three years in three equal annual  installments, subject to

continued employment on each vesting date. Vested options are exercisable at any  time until 10 years
from the date of the option grant, subject to earlier expirations under certain terminations of service
and other conditions. The stock options granted have an exercise price equal to the closing stock price
of our common stock on the grant date.

Continuous Employment Conditions

At September 30, 2015, we have outstanding  628,684 unvested  time-based stock options under  the

2014 Plan or our prior equity incentive  plans (collectively, the  Plans), which will vest on the basis of
continuous employment. All of the time-based options vest ratably during the period of service.

(1) Aggregate intrinsic value is calculated based on the difference  between our  closing  stock
price at year end and the exercise price,  multiplied by the  number of in-the-money
options and represents the pre-tax amount that would have been received by the  option
holders, had they all exercised all their options on the  fiscal year  end date.

The total intrinsic value of options exercised  during  the years ended September  30, 2015, 2014  and

2013 was $1,540,000, $34,593,000 and $25,519,000, respectively.  For the years ended September 30,
2015, 2014 and 2013, we recorded $3,618,000, $2,946,000 and $1,713,000,  respectively, of stock-based
compensation expense related to these options that  is included within selling, general and
administrative expenses. At September 30, 2015, the  unrecognized stock-based compensation related to
these options was $4,242,000 and is expected to be recognized over a weighted-average period of
1.7 years. Cash received from the exercise  of  stock options by  us during the years ended September 30,
2015, 2014 and 2013 was $822,000, $9,643,000 and $9,893,000, respectively.

Restricted Stock Units and Restricted  Stock

In the year ended September 30, 2015, we granted 472,412 shares of restricted  common stock to
employees. These shares are eligible  to  vest over three  years in three equal annual installments, subject
to continued employment on each vesting  date. During the years ended September 30, 2015,  2014 and
2013, we granted 73,662, 26,874 and 44,286, respectively,  of  restricted common shares to our directors.
During  fiscal year  2015, we granted performance-related restricted stock  to certain  executives,  which
vest after three years based on the achievement of  a certain operational goal. The stock-based
compensation expense for the performance awards is determined based  on the probability of achieving
the performance goal which is assessed  by management  on a quarterly basis  until vesting. For  the years
ended September 30, 2015, 2014 and  2013,  we recorded  $4,273,000,  $2,561,000 and $1,681,000,
respectively, of stock-based compensation  expense related to restricted stock that is included  within
selling, general and administrative expenses. The restricted  stock awards do not contain any redemption

provisions that are not within our control. Accordingly, these restricted stock awards  have been
accounted for as our stockholders’ equity. At September 30, 2015, the unrecognized stock-based
compensation related to restricted stock awards was $5,731,000 and is expected  to be recognized over a
weighted-average period of 2.1 years.

Restricted share activity during the year ended September 30,  2015 was as  follows:

(1) Under the terms of their respective restricted stock award agreements, holders of

restricted stock have the same voting rights as  common stock shareholders; such rights
exist even if the shares of restricted stock  have not vested.

Fair value of our restricted shares is based  on our closing stock price on the date of grant. The fair

value of shares that were vested during the years ended September 30, 2015, 2014 and 2013 was
$3,126,000, $2,807,000 and $1,764,000, respectively. The fair value of shares  that  were granted during
the years ended September 30, 2015, 2014  and 2013 was $8,766,000, $4,294,000 and  $3,426,000,
respectively. The weighted average fair value at the grant  date for restricted shares issued during the
years ended September 30, 2015, 2014 and 2013 was $16.05, $20.88 and  $13.52, respectively. Due to tax
deductions associated with option exercises and restricted share activities, we realized a tax shortfall of
$87,000 for the year ended September  30, 2015 and tax benefits  of $10,235,000 and $6,879,000 for the
years ended September 30, 2014 and 2013, respectively. The realized tax shortfall and tax benefits were
recorded to the additional paid in capital  account in our stockholders’ equity.

Stock-Based Compensation

We use the Black-Scholes option pricing model  to  determine  the fair  value of stock options. The
determination of the fair value of stock-based  payment awards on the date of grant using an option-
pricing model is affected by our stock price as well as assumptions regarding complex and  subjective
variables. These variables include the  expected stock price volatility over the  term of the awards,
risk-free interest rate and expected dividends.

We estimated expected volatility based on historical data of comparable public companies. The

expected term, which represents the period  of  time that options granted are expected to be
outstanding, is estimated based on guidelines provided in U.S. Securities and Exchange Commission
Staff Accounting Bulletin No. 110 and represents the average of the  vesting tranches and contractual
terms. The risk-free rate assumed in valuing the options is  based on the U.S. Treasury  rate in effect at
the time of grant for the expected term of the option.  We do not anticipate paying any cash dividends
in the foreseeable future and, therefore, used an expected dividend yield of  zero in the option pricing
model. Compensation expense is recognized only for  those options  expected  to  vest with forfeitures
estimated based on our historical experience and future expectations. Stock-based compensation awards
are amortized on a straight line basis over a three year period.

Indemnifications

In the normal course of business, we provide indemnifications to our  customers with regard to

certain products and enter into contracts  and agreements that may contain representations and
warranties and provide for general indemnifications. Our maximum exposure under many of these
agreements is not quantifiable as we  have a limited  history of prior indemnification claims and
payments. Payments we have made under such agreements have not had a material adverse effect on
our results of operations, cash flows, or financial  position. However, we could incur costs in the future
as a result of indemnification obligations.

Litigation

We are involved in various legal matters that arise in the  ordinary  course of business.

Management, after consulting with outside legal counsel, believes that the ultimate outcome of such
matters will not have a material adverse effect on our financial position, results of  operations or cash
flows. There can be no assurance, however, that such actions will not be material or adversely affect
our business, financial position and results  of operations or cash flows.

Note 18. Employee Benefit Plan

We maintain a 401(k) defined contribution plan and a retirement saving plan  for the benefit of our
eligible employees. All U.S. full-time employees  who have completed at least one full month of service
and are at least 20 years of age are eligible to participate in the plans. Eligible employees may elect to
contribute up to 60% of their eligible  compensation.  We made contributions of $2,138,000, $1,580,000
and $945,000 during the years ended September 30, 2015, 2014 and 2013, respectively.

Note 21. Segment  Reporting

We  are organized based on geographic location. Our reportable segments are  North America and

Rest of World.

We evaluate segment performance based on segment operating earnings or loss. Each segment
reports its results of operations and makes requests  for capital expenditures and acquisition funding to
our chief operating decision-maker (CODM).  Our chief executive officer serves as  our CODM.

Note 22. Restructuring Activities

We record costs associated with involuntary separation  programs when management has approved
the plan for separation, the affected employees are identified, and it is unlikely that actions required to
complete the separation plan will change significantly.

In September 2015, we committed to a Global Restructuring  Plan, which involved the immediate

elimination of redundant positions and  the closure and consolidation of various  facilities in order to
realign our workforce to the growth areas of  our business and to streamline our operations in order to
increase  efficiency and effectiveness. We anticipate that  actions under  the Global Restructuring Plan
will continue through the year ending September 30, 2016.

In connection with the Global Restructuring Plan, we recorded total initial expenses of $4,522,000,

consisting of $2,128,000 of employee severance and related costs and $2,394,000 related to the
termination of leases. Of these amounts, $2,563,000 was recorded in North America and $1,959,000 in
Rest of World. Such expenses were recorded in selling,  general and administrative expenses in the
consolidated statements of comprehensive (loss) income.

No material amounts related to the Global Restructuring Plan  were paid in the year ended
September 30, 2015. The actual costs related  to  the Global Restructuring Plan may  be  higher than  the
amount we accrued as of September  30, 2015, as our  implementation of this plan progresses during the
year ending September 30, 2016. We are not able to quantify the additional costs  at the time of the
filing of this Annual Report on Form 10-K.

ITEM 9A. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

Our management, with the participation of the chief executive officer  and chief financial officer,

evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in
Rules 13a-15(e) and 15d-15(e)) as of  the end of the period covered by  this report.  Based on this
evaluation, and as described below under  ‘‘Management’s Report on  Internal Control over Financial
Reporting,’’ our chief executive officer and chief  financial officer have  concluded that our disclosure
controls and procedures were not effective as of September 30, 2015,  because of the material
weaknesses described below.

In light of the material weaknesses, management performed  additional  analyses  and supplementary

review procedures and has concluded that  the audited  consolidated financial  statements  contained in
this  Annual Report on Form 10-K fairly  present, in  all material respects,  our financial condition, results
of operations and  cash flows for the fiscal years presented in conformity  with generally accepted
accounting principles. Additionally, these  material  weaknesses did not  result in any material
misstatements of the Company’s audited consolidated financial statements and disclosures for the year
ended September 30, 2015.

Management’s Report on Internal Control Over  Financial Reporting

Our management is responsible for establishing and maintaining adequate internal  control over

financial reporting (as defined in Rules 13a-15(f) and 15d-15(f)  of the Exchange  Act).  Under the
supervision and with the participation  of  our management,  including the  chief executive officer and
chief financial officer, we conducted  an  evaluation of the  effectiveness  of the Company’s  internal
control over financial reporting as of  September  30, 2015 based on the  framework established in
Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of
the Treadway Commission (COSO). This assessment  identified material weaknesses in our  internal
control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies,
in internal control over financial reporting, such that there  is a reasonable possibility that a material
misstatement of the Company’s annual or  interim  financial  statements  will not be prevented or detected
on a timely basis. As a result of these  material weaknesses,  management has concluded  that  our
internal control over financial reporting was  not  effective as of September  30, 2015.

The existing material weakness we identified relates  to  a lack of a  sufficient complement  of
accounting and financial reporting personnel with an appropriate  level  of  accounting knowledge and
experience commensurate with our financial reporting requirements. This material weakness
contributed to the following two material weaknesses. We  did not maintain effective controls over  the
preparation and review of account reconciliations. Specifically, our controls  over the reconciliation of
our  balance sheet accounts did not operate effectively. We also did not maintain effective controls over
the integration of policies, practices and  controls over the Haas business unit. These material
weaknesses resulted in certain immaterial audit adjustments to the Company’s  consolidated  financial
statements for the year ended September  30, 2015. These material weaknesses could result in
misstatements of substantially all accounts  and disclosures that would  result in a material misstatement
to the annual or interim consolidated financial  statements that would not be prevented or  detected.

The effectiveness of our internal control over financial reporting as of  September 30, 2015 has
been audited by PricewaterhouseCoopers  LLP,  an independent registered public accounting firm, as
stated in their report, which is included in Item 8 of this Annual Report on Form 10-K.

Remediation Activities

On February 28, 2014, we acquired Haas as part of our growth strategy. Throughout fiscal 2015,
our accounting and financial reporting personnel were  constrained by the continued integration of Haas
and increased attrition attributable to the integration,  as well as openings at senior financial and
organizational positions for part of the fiscal year. Although we filled most of these positions during
fiscal 2015, an adequate period of time is required in order to institute  the appropriate policies,
procedures and processes, and to demonstrate effectiveness and oversight. As a result, the material
weakness identified in fiscal 2014 still existed  as of September  30, 2015. This material weakness led to
other material weaknesses in the review of account reconciliations and the integration of policies,
practices and controls over the Haas business unit as  of September 30, 2015.

In some cases, such as in the case of Haas, the companies we acquire may not have invested in
adequate systems or staffing to meet public company financial  reporting  standards. In addition, we have
acquired companies that currently operate on a variety of systems, which makes process standardization
more difficult. Because of this, we plan to convert some or  all subsidiaries to our systems over time,
depending on available resources and the level of materiality a particular entity might have. We believe
this will allow for easier comparison and reconciliation across companies and more timely
consolidations. The transition for the  first subsidiary to the new  platform was completed in  the three
months ended March 31, 2015. In addition, our objective is to centralize some accounting functions at
our headquarters location, rather than having such activities performed at each subsidiary. We believe
having a majority of accounting and numerous internal controls performed where our senior
management is located will allow review and remediation to occur quickly. We plan  to  hire additional
accounting, audit, controls and financial reporting personnel at our  headquarters to meet this objective.

The following remedial actions have been taken in fiscal 2015:

• Engaged a consulting firm with technical expertise in accounting and  SEC reporting matters to
provide assistance and oversight of the fiscal 2014 year-end close and the  preparation of the
Annual Report on Form 10-K for the  year  ended September 30, 2014. The consulting firm has
continued to assist with the preparation of our periodic reports.

• Filled openings at senior financial and organizational leadership roles  in fiscal 2015:

• Global controller started in January  2015

• Chief executive officer started in May 2015

• Chief financial officer started in May 2015

• Executive vice president of  strategy and business process development started in July 2015

• Restructured and reorganized our finance department, as well  as other departments, to capitalize

on the collective skills, abilities, and  expertise of our resources based on our assessment and
analysis of our combined talent pool from the Haas acquisition. Where gaps were identified, we
actively filled key roles and continue  to  seek additional resources.

• Added qualified and experienced financial  reporting staff in the  finance department to ensure

that it has sufficient depth, skills, and experience to prepare our financial statements and
disclosures in accordance with GAAP. Additional experienced staff include:

• New treasury manager promoted in August 2015

• New director of SEC reporting and  technical  accounting started  in September 2015

Changes in Internal Control over Financial Reporting

As described in ‘‘—Remediation Activities’’ above, we promoted a new treasury manager in August

2015 and hired a new director of SEC reporting and technical accounting, and a new internal  audit
manager in September 2015, which are changes in  internal control over financial reporting during the
quarter ended September 30, 2015 that have  materially affected, or are reasonably likely to materially
affect, the Company’s internal control over financial  reporting. Other  than these actions, there have
been no changes in our internal control over financial reporting during the quarter ended
September 30, 2015 that have materially  affected, or are reasonably likely to materially affect, the
Company’s internal control over financial reporting.

ITEM 9B. OTHER INFORMATION

None.

• New internal audit manager started in September 2015

• Enhanced controls around the identification,  documentation  and  application of technical

accounting guidance with particular emphasis on  events outside the ordinary  course  of  business.
These controls include the implementation of additional supervision and review activities by
qualified personnel, the preparation of formal  accounting memoranda to support our conclusions
on technical accounting matters and the development  and  use of checklists and  research  tools to
assist in compliance with GAAP for  complex accounting issues.

• Formed a disclosure committee comprised of members of our  financial management and

representatives from our accounting, legal, and investor relations departments to address and
coordinate SEC filings and investor communications, the  minutes of which are reviewed  with the
audit committee.

• Engaged a professional accounting  services  firm  to  help us assess and  improve our internal

controls for complying with the Sarbanes-Oxley  Act. The process of implementing an effective
financial reporting system is a continuous effort  that requires us to anticipate and react to
changes in our business and the economic and regulatory environments and to expend  significant
resources to maintain a financial reporting  system that is adequate to satisfy our  reporting
obligations. As we continue to evaluate and take actions  to improve our  internal control over
financial reporting, we may take additional actions  to  address control deficiencies or modify
certain of the remediation measures described  above.

• Purchased and began implementation  of  new  software that will help automate and improve
certain elements of our financial close and reporting process, including our  consolidations
process. Leveraging technology will simplify  and  reduce routine activities  and will provide
additional time for our finance department  to  focus on  non-routine areas requiring  more
analysis and professional judgment.

We  are also in the process of implementing  and  testing the following:

• Integrating various key processes, systems  and  resources, including implementation of a common

financial system across substantially all of the business. Centralizing processes  will  allow  for
streamlined efforts, reduced redundancies, and  the ability to train  employees to specialize in
their tasks. In turn, maintaining a specialization or an expertise in a certain task or process
means constant learning and creation  of  best practices.

• Enhancing and strengthening our written accounting  and reporting policies and  training
employees on the new policies, which is key to centralizing and standardizing processes.

• Allocating time and resources for training internal accounting personnel,  including our senior
accounting and internal audit personnel, to upgrade skillsets around GAAP, industry standards
and latest accounting and audit updates, as well as certain complex and non-routine transactions.

While significant progress has been made to enhance our  internal control over financial reporting

relating to the material weaknesses, we are still in the  process of implementing  and testing these
processes and procedures and additional time is required to complete implementation  and to assess  and
ensure the sustainability of these procedures. We believe the  above actions will be effective in
remediating the material weaknesses  described above and  we will  continue to devote significant  time
and attention to these remedial efforts.  However,  the material weaknesses cannot be considered
remediated until the applicable remedial controls operate for a sufficient period  of  time and
management has concluded, through  testing, that these controls are  operating effectively.  We intend  to
complete the implementation and testing  of our remediation  plan and remediate the material
weaknesses during fiscal 2016.
