PRODUCTS, SERVICES AND STRATEGIES

Chlor Alkali Products and Vinyls

Products and Services

We have been involved in the chlor alkali industry for more than 125 years and are a major participant in the global chlor 

alkali industry.  Chlorine, caustic soda and hydrogen are co-produced commercially by the electrolysis of salt.  These co-
produced products are produced simultaneously, and in a fixed ratio of 1.0 ton of chlorine to 1.1 tons of caustic soda and 0.03 
tons of hydrogen.  The industry refers to this as an Electrochemical Unit or ECU.  With a demonstrated capacity of 5.8 million 
ECUs as of the end of 2019, we have the largest global chlor alkali capacity, according to data from IHS Markit (IHS).  IHS is a 
global information consulting company established in 1959 that provides information to a variety of industries.

Chlorine is used as a raw material in the production of thousands of products, including vinyls, urethanes, epoxy, water 

treatment chemicals and a variety of other organic and inorganic chemicals.  A significant portion of chlorine production is 
consumed in the manufacture of ethylene dichloride (EDC) and vinyl chloride monomer (VCM), both of which our Chlor 
Alkali Products and Vinyls segment produces.  A large portion of our EDC production is utilized in the production of VCM, but 
we are also one of the largest global participants in merchant EDC sales.  EDC and VCM are precursors for polyvinyl chloride 
(PVC).  PVC is a plastic used in applications such as vinyl siding, pipe, pipe fittings and automotive parts.

Our Chlor Alkali Products and Vinyls segment is one of the largest global marketers of caustic soda, including caustic 

soda produced by The Dow Chemical Company (Dow) in Brazil.  The off-take arrangement with Dow in Brazil entitles the 
Chlor Alkali Products and Vinyls segment the right to market and sell the caustic soda produced at Dow’s Aratu, Brazil site.  
The diversity of caustic soda sourcing allows us to cost effectively supply customers worldwide.  Caustic soda has a wide 
variety of end-use applications, the largest of which includes water treatment, alumina, pulp and paper, urethanes, detergents 
and soaps and a variety of other organic and inorganic chemicals.

Table of Contents

Our Chlor Alkali Products and Vinyls segment also includes our chlorinated organics business which is the largest global 

producer of chlorinated organic products that include chloromethanes (methyl chloride, methylene chloride, chloroform and 
carbon tetrachloride) and chloroethenes (perchloroethylene, trichloroethylene, and vinylidene chloride).  Chlorinated organics 
participates in both the solvent segment, as well as the intermediate segment of the global chlorocarbon industry with a focus 
on sustainable applications and in applications where we can benefit from our cost advantages.  Intermediate products are used 
as feedstocks in the production of fluoropolymers, fluorocarbon refrigerants and blowing agents, silicones, cellulosics and 
agricultural chemicals.  Solvent products are sold into end uses such as surface preparation, dry cleaning, pharmaceuticals and 
regeneration of refining catalysts.  This business’s unique technology allows us to utilize both hydrochloric acid and chlorinated 
hydrocarbon byproducts (RCls), produced by our other production processes, as raw materials in an integrated system.  These 
manufacturing facilities also consume chlorine, which generates caustic soda production and sales.

We also manufacture and sell other chlor alkali-related products, including hydrochloric acid, sodium hypochlorite 
(bleach) and potassium hydroxide, which we refer to as co-products.  The production of co-products, chlorinated organics 
products and epoxy resins generally consume chlorine as a raw material creating downstream applications that upgrade the 
value of chlorine and enable caustic soda production.  Our industry leadership in the production of chlorinated organics and 
epoxy resins, as well as other co-products, offer us nineteen integrated outlets for our captive chlorine. 

The Chlor Alkali Products and Vinyls segment’s products are delivered by pipeline, marine vessel, deep-water and 

coastal barge, railcar and truck.  Our logistics and terminal infrastructure provides us with geographically advantaged storage 
capacity and provides us with a private fleet of trucks, tankers and trailers that expands our geographic coverage and enhances 
our service capabilities.  At our largest integrated product sites, our deep-water access enables us to reach global markets.

Our Chlor Alkali Products and Vinyls segment maintains strong relationships with Dow as both a customer and supplier.  

These relationships are maintained through long-term cost based contracts that provide us with a reliable supply of key raw 
materials and predictable and consistent demand for our end use products.  Key products sold to Dow include chlorine, caustic 
soda, chlorinated organics and VCM.  Key raw materials received from Dow include ethylene and electricity.  Ethylene is 
supplied for the vinyls business under a long-term supply arrangement with Dow whereby we receive ethylene at integrated 
producer economics.  

Electricity, salt, ethylene and methanol are the major purchased raw materials for our Chlor Alkali Products and Vinyls 

segment.  Electricity is the single largest raw material component in the production of Chlor Alkali Products and Vinyls’ 
products.  Approximately 74% of our electricity is generated from natural gas or hydroelectric sources.  Approximately 66% of 
our salt requirements are met by internal supply.  Methanol is sourced domestically and internationally primarily from large 
producers.  The high volume nature of the chlor alkali industry places an emphasis on cost management and we believe that our 
scale, integration and raw material positions make us one of the low cost producers in the industry.

provide expansion opportunities.

Products and Services

Epoxy

The Epoxy business was one of the first major manufacturers of epoxy products, and has continued to build on more 
than half a century of history through product innovation and technical excellence.  According to data from IHS, the Epoxy 
segment is one of the largest fully integrated global producers of epoxy resins, curing agents and intermediates.  The Epoxy 
segment has a favorable manufacturing cost position which is driven by a combination of scale and integration into low cost 
feedstocks (including chlorine, caustic soda, allylics and aromatics).  With its advantaged cost position, the Epoxy segment is 
among the lowest cost producers in the world.  The Epoxy segment produces and sells a full range of epoxy materials, 
including upstream products such as allyl chloride (Allyl) and epichlorohydrin (EPI), midstream products such as liquid epoxy 
resins (LER) and solid epoxy resins (SER) and downstream products such as differentiated epoxy resins and additives.

The Epoxy segment serves a diverse array of applications, including wind energy, electrical laminates, consumer goods 

and composites, as well as numerous applications in civil engineering and protective coatings.  The Epoxy segment has 
important relationships with established customers, some of which span decades.  The Epoxy segment’s primary geographies 
are North America and Western Europe.  The segment’s product is delivered primarily by marine vessel, deep-water and coastal 
barge, railcar and truck.

Allyl is used not only as a feedstock in the production of EPI, but also as a chemical intermediate in multiple industries 

and applications, including water purification chemicals.  EPI is primarily produced as a feedstock for use in the business’s 
epoxy resins, and also sold to epoxy producers globally who produce their own resins for end use segments such as coatings 
and adhesives.  LER is manufactured in liquid form and cures with the addition of a hardener into a thermoset solid material 
offering a distinct combination of strength, adhesion and chemical resistance that is well-suited to coatings and composites 
applications.  SER is processed further with bisphenol (BisA) to meet specific end market applications.  While LER and SER 
are sold externally, a significant portion of LER production is further converted into differentiated epoxy resins where value-
added modifications produce higher margin resins.

Our Epoxy segment maintains strong relationships with Dow as both a customer and supplier.  These relationships are 
maintained through long-term cost based contracts that provide us with a reliable supply of key raw materials.  Key products 
sold to Dow include aromatics and key raw materials received from Dow include benzene and propylene.

The Epoxy segment’s production economics benefit from its integration into chlor alkali and aromatics which are key 

inputs in epoxy production.  This fully integrated structure provides both access to low cost materials and significant 
operational flexibility.  The Epoxy segment operates an integrated aromatics production chain producing cumene, phenol, 
acetone and BisA for internal consumption and external sale.  The Epoxy segment’s consumption of chlorine enables the Chlor 
Alkali Products and Vinyls segment to generate caustic soda production and sales.  Chlorine used in our Epoxy segment is 
transferred at cost from the Chlor Alkali Products and Vinyls segment.

Focus on Product Line Growth.  With a long record of pioneering new product offerings, Winchester has built a strong 
reputation as an industry innovator.  This includes the introduction of reduced-lead and non-lead products, which are growing 
in popularity for use in indoor shooting ranges and for outdoor hunting.

Cost Reduction Strategy.  Winchester plans to continue to focus on strategies that will lower our costs.  During 2018, we 
initiated a cost reduction plan which has permanently closed the ammunition assembly operations at our Winchester facility in 
Geelong, Australia.  Subsequent to the facility’s closure, product for customers in the region are sourced from Winchester 
manufacturing facilities located in the United States. 

INTERNATIONAL OPERATIONS

Olin has an international presence, including the geographic regions of Europe, Asia Pacific and Latin America.  
Approximately 41% of Olin’s 2019 sales were generated outside of the U.S., including 32% of our Chlor Alkali Products and 
Vinyls 2019 segment sales, 67% of our Epoxy 2019 segment sales and 9% of our Winchester 2019 segment sales.  See Note 21 
“Segment Information” of the notes to consolidated financial statements contained in Item 8, for geographic segment data.  We 
are incorporating our segment information from that Note into this section of our Form 10-K.

CUSTOMERS AND DISTRIBUTION

Products we sell to industrial or commercial users or distributors for use in the production of other products constitute a 

major part of our total sales.  We sell some of our products, such as epoxy resins, caustic soda and sporting ammunition, to a 
large number of users or distributors, while we sell other products, such as chlorine and chlorinated organics, in substantial 
quantities to a relatively small number of industrial users.  Olin has significant relationships with a few customers including 
Dow, who was our largest customer by revenue in 2019, representing approximately 15% of our total sales.  We expect this 
relationship to continue to be significant to Olin and to represent more than 10% of our annual sales in the future.  No other 
single customer accounted for more than 5% of sales.  We discuss the customers for each of our three business segments in 
more detail above under “Products and Services.”

We market most of our products and services primarily through our sales force and sell directly to various industrial 

customers, mass merchants, retailers, wholesalers, other distributors and the U.S. Government and its prime contractors.

Sales to all U.S. Government agencies and sales under U.S. Government contracting activities in total accounted for 

approximately 3% of sales in 2019.  Because we engage in some government contracting activities and make sales to the U.S. 
Government, we are subject to extensive and complex U.S. Government procurement laws and regulations.  These laws and 
regulations provide for ongoing government audits and reviews of contract procurement, performance and administration.  
Failure to comply, even inadvertently, with these laws and regulations and with laws governing the export of munitions and 
other controlled products and commodities could subject us or one or more of our businesses to civil and criminal penalties, 
and under certain circumstances, suspension and debarment from future government contracts and the exporting of products for 
a specified period of time.

BACKLOG

The total amount of estimated backlog was approximately $151 million and $224 million as of January 31, 2020 and 
2019, respectively.  The backlog orders are associated with contractual orders in our Winchester business.  Backlogs in our 
other businesses are not significant.  Backlog is comprised of all open customer orders which have been received, but not yet 
shipped.  The backlog was estimated based on expected volume to be shipped from firm contractual orders, which are subject 
to customary terms and conditions, including cancellation and modification provisions.  Approximately 96% of contracted 
backlog as of January 31, 2020 is expected to be fulfilled during 2020, with the remainder expected to be fulfilled during 2021.

COMPETITION

We are in active competition with businesses producing or distributing the same or similar products, as well as, in some 

instances, with businesses producing or distributing different products designed for the same uses.

Chlor alkali manufacturers in North America, with approximately 17 million tons of chlorine and 18 million tons of 

caustic soda capacity, accounted for approximately 17% of worldwide chlor alkali production capacity.  In 2019, according to 
IHS, we have the largest chlor alkali capacity in North America and globally.  While the technologies to manufacture and 
transport chlorine and caustic soda are widely available, the production facilities require large capital investments, and are 

10

Table of Contents

subject to significant regulatory and permitting requirements.  Approximately 76% of the total North American chlor alkali 
capacity is located in the U.S. Gulf Coast region.  There is a worldwide market for caustic soda, which attracts imports and 
allows exports depending on market conditions.  Other large chlor alkali producers in North America include The Occidental 
Petroleum Corporation (Oxy) and Westlake Chemical Corporation (Westlake).  

We are also a leading integrated global producer of chlorinated organic products with a strong cost position due to our 

scale and access to chlor alkali feedstocks.  This industry includes large diversified producers such as Oxy, Westlake and 
Solvay S.A., as well as multiple producers located in China.

We are a major global fully integrated epoxy producer, with access to key low cost feedstocks and a cost advantaged 
infrastructure.  With its advantaged cost position, the Epoxy segment is among the lowest cost producers in the world.  The 
markets in which our Epoxy segment operates are highly competitive and are dependent on significant capital investment, the 
development of proprietary technology and maintenance of product research and development.  Among our competitors are 
Huntsman Corporation (Huntsman) and Hexion, Inc., as well as multiple producers located in Asia.  

We are among the largest manufacturers in the U.S. of commercial small caliber ammunition based on independent 

market research sponsored by the National Shooting Sports Foundation (NSSF).  Formed in 1961, NSSF has a membership of 
more than 12,000 manufacturers, distributors, firearms retailers, shooting ranges, sportsmen’s organizations and publishers.  
According to NSSF-sponsored research, our Winchester business, Vista Outdoor Inc. (Vista), and Remington Outdoor 
Company, Inc. (Remington) are the three largest commercial ammunition manufacturers in the U.S.  The ammunition industry 
is highly competitive with Olin, Vista, Remington, numerous smaller domestic manufacturers and foreign producers competing 
for sales to the commercial ammunition customers.  Many factors influence our ability to compete successfully, including price, 
delivery, service, performance, product innovation and product recognition and quality, depending on the product involved.

EMPLOYEES

As of December 31, 2019, we had approximately 6,500 employees, with 5,300 working in the U.S. and 1,200 working in 

foreign countries.  Various labor unions represent a significant number of our hourly-paid employees for collective bargaining 
purposes.

The following labor contract will be required to be negotiated in 2020:

Location
Lake City Army Ammunition Plant (Winchester)

Number of Employees
1,447*

Expiration Date
October 2020

*Lake City Plant personnel are not employees of Olin as of December 31, 2019.

While we believe our relations with our employees and their various representatives are generally satisfactory, we cannot 

assure that we can conclude this labor contract or any other labor agreements without work stoppages and cannot assure that 
any work stoppages will not have a material adverse effect on our business, financial condition or results of operations.

RESEARCH ACTIVITIES; PATENTS

Our research activities are conducted on a product-group basis at a number of facilities.  Company-sponsored research 

expenditures were $16.5 million in 2019, $14.9 million in 2018 and $14.5 million in 2017.

We own or license a number of patents, patent applications and trade secrets covering our products and processes.  We 
believe that, in the aggregate, the rights under our patents and licenses are important to our operations, but we do not consider 
any individual patent, license or group of patents and licenses related to a specific process or product to be of material 
importance to our total business.

SEASONALITY

Our sales are affected by the cyclicality of the economy and the seasonality of several industries we serve, including 

building and construction, coatings, infrastructure, electronics, automotive, bleach, refrigerants and ammunition.  The 
seasonality of the ammunition business is typically driven by the U.S. fall hunting season.  Our chlor alkali businesses 
generally experience their highest level of activity during the spring and summer months, particularly when construction, 
refrigerants, coatings and infrastructure activity is higher.  The chlor alkali industry is cyclical, both as a result of changes in 
demand for each of the co-produced products and as a result of the large increments in which new capacity is added and 

11

Table of Contents

removed.  Because chlorine and caustic soda are produced in a fixed ratio, the supply of one product can be constrained both by 
the physical capacity of the production facilities and/or by the ability to sell the co-produced product.  Prices for both products 
respond rapidly to changes in supply and demand.  The cyclicality of the chlor alkali industry has further impacts on 
downstream products.  We have significant diversification of our chlorine outlets, which allow us to better manage the cyclical 
nature of the industry.

RAW MATERIALS AND ENERGY

Basic raw materials are processed through an integrated manufacturing process to produce a number of products that are 
sold at various points throughout the process.  We purchase a portion of our raw material requirements and also utilize internal 
resources, co-products and finished goods as raw materials for downstream products.  We believe we have reliable sources of 
supply for our raw materials under normal market conditions.  However, we cannot predict the likelihood or impact of any 
future raw material shortages.

The principal basic raw materials for our production of Chlor Alkali Products and Vinyls’ products are electricity, salt, 
ethylene and methanol.  Electricity is the predominant energy source for our manufacturing facilities.  Approximately 74% of 
our electricity is generated from natural gas or hydroelectric sources.  We have long-term power supply contracts with Dow in 
addition to utilizing our own power assets, which allow for cost differentiation at specific U.S. manufacturing sites.  A portion 
of our purchases of raw materials, including ethylene, are made under long-term supply agreements, while approximately 66% 
of the salt used in our Chlor Alkali Products and Vinyls segment is produced from internal resources.  Methanol is sourced 
domestically and internationally primarily from large producers.

The Epoxy segment’s principal raw materials are chlorine, benzene, propylene and aromatics, which consist of cumene, 

phenol, acetone and BisA.  A portion of our purchases of raw materials, including benzene, propylene and a portion of our 
aromatics requirements, are made under long-term supply agreements, while a portion of our aromatics requirements are 
produced from our integrated production chain.  Chlorine is predominately sourced from our Chlor Alkali Products and Vinyls 
segment.

Lead, brass and propellant are the principal raw materials used in the Winchester business.  We typically purchase our 

ammunition cartridge case cups and copper-based strip, and propellants pursuant to multi-year contracts.

We provide additional information with respect to specific raw materials in the tables set forth under “Products and 

Services.”

ENVIRONMENTAL AND TOXIC SUBSTANCES CONTROLS

As is common in our industry, we are subject to environmental laws and regulations related to the use, storage, handling, 

generation, transportation, emission, discharge, disposal and remediation of, and exposure to, hazardous and non-hazardous 
substances and wastes in all of the countries in which we do business.

The establishment and implementation of national, state or provincial and local standards to regulate air, water and land 

quality affect substantially all of our manufacturing locations around the world.  Laws providing for regulation of the 
manufacture, transportation, use and disposal of hazardous and toxic substances, and remediation of contaminated sites have 
imposed additional regulatory requirements on industry, particularly the chemicals industry.  In addition, implementation of 
environmental laws has required and will continue to require new capital expenditures and will increase operating costs.

We are a party to various government and private environmental actions associated with former waste disposal sites and 

past manufacturing facilities.  Charges to income for investigatory and remedial efforts were $25.3 million, $7.3 million and 
$10.3 million for the years ended December 31, 2019, 2018 and 2017, respectively.  These charges may be material to 
operating results in future years.  These charges do not include insurance recoveries for costs incurred and expensed in prior 
periods.

In connection with the October 5, 2015 acquisition of Dow’s U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics 
and Global Epoxy businesses, the prior owner of the businesses retained liabilities relating to releases of hazardous materials 
and violations of environmental law to the extent arising prior to October 5, 2015.

See our discussion of our environmental matters contained in Item 3—“Legal Proceedings” below, Note 22 

“Environmental” of the notes to consolidated financial statements contained in Item 8 and Item 7—“Management’s Discussion 
and Analysis of Financial Condition and Results of Operations.”

Product Responsibility

We take great pride in distributing and handling our products safely and enabling our customers to do the same.  Our 

product stewardship and quality practices are aligned with our core values, the American Chemistry Council’s Product 
Safety Code under Responsible Care®, and other globally recognized standards.  We apply these standards to our chemical 
business segments and relevant subsidiaries to ensure compliance with applicable global regulations, evaluation, 
continuous improvement and transparency of relevant production information.  Additionally, Winchester ammunition is 
designed and manufactured in accordance with the voluntary industry standards published by the Sporting Arms and 
Ammunition Manufacturers’ Institute.  We are deeply committed to ammunition education and advocate strongly for the 
belief that it is important to take the necessary steps to be trained and educated when handling and using a firearm for 
recreational purposes, both for experienced and novice participants.  Our goal is to meet or exceed guidelines in every 
instance.  Olin Leadership demonstrates its commitment to these standards through active participation and communication 
concerning product safety, within our organization and to external stakeholders.

Item 1A.  RISK FACTORS

In addition to the other information in this Form 10-K, the following factors should be considered in evaluating Olin and 

our business.  All of our forward-looking statements should be considered in light of these factors.  Additional risks and 
uncertainties that we are unaware of or that we currently deem immaterial also may become important factors that affect us.

Sensitivity to Global Economic Conditions and Cyclicality—Our operating results could be negatively affected during 

economic and industry downturns.

The businesses of most of our customers, particularly our vinyls, urethanes and pulp and paper customers are, to varying 

degrees, cyclical and have historically experienced periodic downturns.  These economic and industry downturns have been 
characterized by diminished product demand, excess manufacturing capacity and, in some cases, lower average selling prices.  
Therefore, any significant downturn in our customers’ businesses or in global economic conditions could result in a reduction 
in demand for our products and could adversely affect our results of operations or financial condition.

Although a majority of our sales are within North America, a large part of our financial performance is dependent upon a 

healthy economy beyond North America because we have a significant amount of sales abroad and our customers sell their 
products abroad.  As a result, our business is and will continue to be affected by general economic conditions and other factors 
in Europe, Asia Pacific, particularly China, and Latin America, including fluctuations in interest rates, customer demand, labor 
and energy costs, currency changes and other factors beyond our control, such as public health epidemics.  The demand for our 
products and our customers’ products is directly affected by such fluctuations.  In addition, our customers could decide to move 
some or all of their production to locations that are more remote from our facilities, and this could reduce demand for our 
products.  We cannot assure you that events having an adverse effect on the industries in which we operate will not occur or 
continue, such as a downturn in the European, Asian Pacific, particularly Chinese, Latin American, or world economies, 
increases in interest rates or unfavorable currency fluctuations.  Economic conditions in other regions of the world, 
predominantly Asia and Europe, can increase the amount of caustic soda produced and available for export to North America.  
The increased caustic soda supply can put downward pressure on our caustic soda prices, negatively impacting our profitability. 

Cyclical Pricing Pressure—Our profitability could be reduced by declines in average selling prices of our products, 

particularly chlorine and caustic soda.

Our historical operating results reflect the cyclical and sometimes volatile nature of the chemical and ammunition 
industries.  We experience cycles of fluctuating supply and demand in each of our business segments, particularly in our Chlor 
Alkali Products and Vinyls segment, which result in changes in selling prices.  Periods of high demand, tight supply and 
increasing operating margins tend to result in increases in capacity and production until supply exceeds demand, generally 
followed by periods of oversupply and declining prices.  Another factor influencing demand and pricing for chlorine and 
caustic soda is the price of natural gas.  Higher natural gas prices increase our customers’ and competitors’ manufacturing costs, 
and depending on the ratio of crude oil to natural gas prices, could make them less competitive in world markets. 

14

Table of Contents

In the chlor alkali industry, price is the major supplier selection criterion.  We have little or no ability to influence prices 
in these large commodity markets.  Decreases in the average selling prices of our products could have a material adverse effect 
on our profitability.  While we strive to maintain or increase our profitability by reducing costs through improving production 
efficiency, emphasizing higher margin products and by controlling transportation, selling and administration expenses, we 
cannot assure you that these efforts will be sufficient to fully offset the effect of possible decreases in pricing on operating 
results.

Because of the cyclical nature of our businesses, we cannot assure you that pricing or profitability in the future will be 

comparable to any particular historical period, including the most recent period shown in our operating results.  We cannot 
assure you that the chlor alkali industry will not experience adverse trends in the future, or that our business, financial condition 
and results of operations will not be adversely affected by them.

Our Winchester and Epoxy segments are also subject to changes in operating results as a result of cyclical pricing 
pressures, but to a lesser extent than our Chlor Alkali Products and Vinyls segment.  Selling prices of ammunition and epoxy 
materials are affected by changes in raw material costs and availability, customer demand, industry production capacity and 
declines in average selling prices of products of our Winchester and Epoxy segments could adversely affect our profitability.

Suppliers—We rely on a limited number of third-party suppliers for specified feedstocks and services. 

We obtain a significant portion of our raw materials from a few key suppliers.  If any of these suppliers fail to meet their 

obligations under present or any future supply agreements, we may be forced to pay higher prices or incur higher costs to 
obtain the necessary raw materials.  Any interruption of supply or any price increase of raw materials could have a material 
adverse effect on our business, financial condition and results of operations.  We have entered into long-term agreements with 
Dow to provide specified feedstocks and services for a number of our facilities.  These facilities are dependent upon Dow’s 
infrastructure for services such as wastewater and ground water treatment.  Any failure of Dow to perform its obligations under 
those agreements could adversely affect the operation of the affected facilities and our business, financial condition and results 
of operations.  Most of these agreements are automatically renewable after their initial terms, but may be terminated by us or 
Dow after specified notice periods.  If we are required to obtain an alternate source for these feedstocks or services, we may not 
be able to obtain pricing on as favorable terms.  Additionally, we may be forced to pay additional transportation costs or to 
invest in capital projects for pipelines or alternate facilities to accommodate railcar or other delivery methods or to replace 
other services. 

A vendor may choose, subject to existing contracts, to modify its relationship due to general economic concerns or 
concerns relating to the vendor or us, at any time.  Any significant change in the terms that we have with our key suppliers 
could materially and adversely affect our business, financial condition and results of operations, as could significant additional 
requirements from suppliers that we provide them additional security in the form of prepayments or posting letters of credit.

Raw Materials—Availability of purchased feedstocks and energy, and the volatility of these costs, impact our 

operating costs and add variability to earnings. 

Purchased feedstock and energy costs account for a substantial portion of our total production costs and operating 

expenses.  We purchase certain raw materials as feedstocks. 

Feedstock and energy costs generally follow price trends in crude oil and natural gas, which are sometimes volatile.  
Ultimately, the ability to pass on underlying cost increases in a timely manner or at all is dependent on market conditions.  
Conversely, when feedstock and energy costs decline, selling prices generally decline as well.  As a result, volatility in these 
costs could impact our business, financial condition and results of operations.

If the availability of any of our principal feedstocks is limited or we are unable to obtain natural gas or energy from any 
of our energy sources, we may be unable to produce some of our products in the quantities demanded by our customers, which 
could have a material adverse effect on plant utilization and our sales of products requiring such raw materials.  We have long-
term supply contracts with various third parties for certain raw materials, including ethylene, electricity, propylene and 
benzene.  As these contracts expire, we may be unable to renew these contracts or obtain new long-term supply agreements on 
terms comparable or as favorable to us, depending on market conditions, which may have a material adverse effect on our 
business, financial condition and results of operations.  In addition, many of our long-term contracts contain provisions that 
allow our suppliers to limit the amount of raw materials shipped to us below the contracted amount in force majeure or similar 
circumstances.  If we are required to obtain alternate sources for raw materials because our suppliers are unwilling or unable to 
perform under raw material supply agreements or if a supplier terminates its agreements with us, we may not be able to obtain 
these raw materials from alternative suppliers or obtain new long-term supply agreements on terms comparable or as favorable 
to us.

Cost Control—Our profitability could be reduced if we experience increasing raw material, utility, transportation or 

logistics costs, or if we fail to achieve targeted cost reductions. 

15

Table of Contents

Our operating results and profitability are dependent upon our continued ability to control, and in some cases reduce, our 

costs.  If we are unable to do so, or if costs outside of our control, particularly our costs of raw materials, utilities, 
transportation and similar costs, increase beyond anticipated levels, our profitability will decline. 

For example, if our feedstock and energy costs increase, and we are unable to control those costs or pass the increased 

costs on to customers, our profitability in our Chlor Alkali Products and Vinyls and Epoxy segments would be negatively 
affected.  Similarly, costs of commodity metals and other materials used in our Winchester business, such as copper and lead, 
can vary.  If we experience significant increases in these costs and are unable to raise our prices to offset the higher costs, the 
profitability in our Winchester business would be negatively affected. 

Third-Party Transportation—We rely heavily on third-party transportation, which subjects us to risks and costs that 

we cannot control, and which risks and costs may have a material adverse effect on our financial position or results of 
operations. 

We rely heavily on railroad, truck, marine vessel, barge and other shipping companies to transport finished products to 

customers and to transport raw materials to the manufacturing facilities used by each of our businesses.  These transport 
operations are subject to various hazards and risks, including extreme weather conditions, work stoppages and operating 
hazards, as well as domestic and international transportation and maritime regulations.  In addition, the methods of 
transportation we utilize, including shipping chlorine and other chemicals by railroad and by barge, may be subject to 
additional, more stringent and more costly regulations in the future.  If we are delayed or unable to ship finished products or 
unable to obtain raw materials as a result of any such new or modified regulations or public policy changes related to 
transportation safety, or these transportation companies’ failure to operate properly, or if there are significant changes in the 
cost of these services due to new additional regulations, or otherwise, we may not be able to arrange efficient alternatives and 
timely means to obtain raw materials or ship goods, which could result in a material adverse effect on our business, financial 
position or results of operations.  If any third-party railroad that we utilize to transport chlorine and other chemicals ceases to 
transport certain hazardous materials, or if there are significant changes in the cost of shipping hazardous materials by rail or 
otherwise, we may not be able to arrange efficient alternatives and timely means to deliver our products or at all, which could 
result in a material adverse effect on our business, financial position or results of operations.

Security and Chemicals Transportation—New regulations on the transportation of hazardous chemicals and/or the 

security of chemical manufacturing facilities and public policy changes related to transportation safety could result in 
significantly higher operating costs. 

The transportation of our products and feedstocks, including transportation by pipeline, and the security of our chemical 
manufacturing facilities are subject to extensive regulation.  Government authorities at the local, state and federal levels could 
implement new or stricter regulations that would impact the security of chemical plant locations and the transportation of 
hazardous chemicals.  Our Chlor Alkali Products and Vinyls and Epoxy segments could be adversely impacted by the cost of 
complying with any new regulations.  Our business also could be adversely affected if an incident were to occur at one of our 
facilities or while transporting products.  The extent of the impact would depend on the requirements of future regulations and 
the nature of an incident, which are unknown at this time. 

Production Hazards—Our facilities are subject to operating hazards, which may disrupt our business. 

We are dependent upon the continued safe and reliable operation of our production facilities.  Our production facilities 

are subject to hazards associated with the manufacture, handling, storage and transportation of chemical materials and products 
and ammunition, including leaks and ruptures, explosions, fires, inclement weather and natural disasters, unexpected utility 
disruptions or outages, unscheduled downtime, equipment failure, terrorism, transportation interruptions, transportation 
accidents involving our chemical products, chemical spills and other discharges or releases of toxic or hazardous substances or 
gases and environmental hazards.  Due to the integrated nature of our large chemical sites, an incident at one plant could impact 
production across multiple plants at a facility.  From time to time in the past, we have had incidents that have temporarily shut 
down or otherwise disrupted our manufacturing, causing production delays and resulting in liability for workplace injuries and 
fatalities.  Some of our products involve the manufacture and/or handling of a variety of explosive and flammable materials.  
Use of these products by our customers could also result in liability if an explosion, fire, spill or other accident were to occur.  
We cannot assure you that we will not experience these types of incidents in the future or that these incidents will not result in 
production delays or otherwise have a material adverse effect on our business, financial condition or results of operations.  
Major hurricanes have caused significant disruption in our operations on the U.S. Gulf Coast, logistics across the region and the 
supply of certain raw materials, which have had an adverse impact on volume and cost for some of our products.  Due to the 
substantial presence we have on the U.S. Gulf Coast, similar severe weather conditions or other natural phenomena in the 
future could negatively affect our results of operations, for which we may not be fully insured. 

16

Table of Contents

Credit Facility—Weak industry conditions could affect our ability to comply with the financial maintenance 

covenants in our senior credit facility. 

Our senior credit facility includes certain financial maintenance covenants requiring us to not exceed a maximum 

leverage ratio and to maintain a minimum coverage ratio. 

Depending on the magnitude and duration of economic or industry downturns affecting our businesses, including 
deterioration in prices and volumes, there can be no assurance that we will continue to be in compliance with these ratios.  If 
we failed to comply with either of these covenants in a future period and were not able to obtain waivers from the lenders, we 
would need to refinance our current senior credit facility.  However, there can be no assurance that such refinancing would be 
available to us on terms that would be acceptable to us or at all. 

Information Security—A failure of our information technology systems, or an interruption in their operation due to 

internal or external factors including cyber-attacks, could have a material adverse effect on our business, financial 
condition or results of operations. 

Our operations are dependent on our ability to protect our information systems, computer equipment and information 
databases from systems failures.  We rely on both internal information technology systems and certain external services and 
service providers to manage the day-to-day operation of our business, operate elements of our manufacturing facilities, manage 
relationships with our employees, customers and suppliers, fulfill customer orders and maintain our financial and accounting 
records.  Failure of any one or more than one of our information technology systems could be caused by internal or external 
events, such as incursions by intruders or hackers, computer viruses, cyber-attacks, failures in hardware or software, or power 
or telecommunication fluctuations or failures.  The failure of our information technology systems to perform as anticipated for 
any reason or any significant breach of security could disrupt our business and result in numerous adverse consequences, 
including reduced effectiveness and efficiency of operations, increased costs or loss of important information, any of which 
could have a material adverse effect on our business, financial condition or results of operations.  We have technology and 
information security processes, periodic external service and service provider reviews, insurance policies and disaster recovery 
plans in place to mitigate our risk to these vulnerabilities.  However, these measures may not be adequate to ensure that our 
operations will not be disrupted or our financial impact minimalized, should such an event occur. 

17

Table of Contents

Integration of Information Technology Systems—Operation on multiple Enterprise Resource Planning (ERP) 

information systems, and the conversion to a new system, may negatively impact our operations. 

We are highly dependent on our information systems infrastructure in order to process orders, track inventory, ship 

products in a timely manner, prepare invoices to our customers, make payments to our suppliers, maintain regulatory 
compliance and otherwise carry on our business in the ordinary course.  We currently operate on multiple ERP information 
systems.  Since we are required to process and reconcile our information from multiple systems, the chance of errors is greater.  
Inconsistencies in the information from multiple ERP systems could adversely impact our ability to manage our business 
efficiently and may result in heightened risk to our ability to maintain our books and records and comply with regulatory 
requirements.  In 2017, we began a multi-year implementation of new enterprise resource planning, manufacturing, and 
engineering systems.  The project includes the required information technology infrastructure (collectively, the Information 
Technology Project).  The project is planned to standardize business processes across the chemicals businesses with the 
objective of maximizing cost effectiveness, efficiency and control across our global operations.  At the end of 2019, Olin had 
successfully converted approximately 35% of our chemical business users to the new enterprise resource planning systems.  
The project is anticipated to be substantially completed during 2020.  The transition to a new ERP system involves numerous 
risks, including: 

• 

• 

• 

• 

• 

• 

diversion of management’s attention away from normal daily business operations;

loss of, or delays in accessing, data;

increased demand on our operations support personnel;

increased costs;

initial dependence on unfamiliar systems while training personnel to use new systems; and

increased operating expenses resulting from training, conversion and transition support activities.

Any of the foregoing could result in a material increase in information technology compliance or other related costs, and 

could materially and negatively impact our business, financial condition or results of operations.

Imbalance in Demand for Our Chlor Alkali Products—A loss of a substantial customer for either our chlorine or 

caustic soda could cause an imbalance in customer demand for these products, which could have an adverse effect on our 
results of operations. 

Chlorine and caustic soda are produced simultaneously and in a fixed ratio of 1.0 ton of chlorine to 1.1 tons of caustic 
soda.  The loss of a substantial chlorine or caustic soda customer could cause an imbalance in customer demand for either our 
chlorine and caustic soda products.  An imbalance in customer demand may require Olin to reduce production of both chlorine 
and caustic soda or take other steps to correct the imbalance.  Since Olin cannot store large quantities of chlorine, we may not 
be able to respond to an imbalance in customer demand for these products quickly or efficiently.  If a substantial imbalance 
occurred, we would need to reduce prices or take other actions that could have a material adverse impact on our business, 
results of operations and financial condition.

Indebtedness—Our indebtedness could adversely affect our financial condition. 

As of December 31, 2019, we had $3,340.8 million of indebtedness outstanding.  Outstanding indebtedness does not 

include amounts that could be borrowed under our $800.0 million senior revolving credit facility, under which $796.5 million 
was available for borrowing as of December 31, 2019 because we had issued $3.5 million of letters of credit.  As of December 
31, 2019, our indebtedness represented 58.0% of our total capitalization.  At December 31, 2019, $2.1 million of our 
indebtedness was due within one year.  Despite our level of indebtedness, we expect to continue to have the ability to borrow 
additional debt. 

Our indebtedness could have important consequences, including but not limited to: 

• 

• 

limiting our ability to fund working capital, capital expenditures, and other general corporate purposes;

limiting our ability to accommodate growth by reducing funds otherwise available for other corporate 
purposes and to compete, which in turn could prevent us from fulfilling our obligations under our 
indebtedness;

• 

limiting our operational flexibility due to the covenants contained in our debt agreements;

18

Table of Contents

• 

• 

• 

to the extent that our debt is subject to floating interest rates, increasing our vulnerability to fluctuations in 
market interest rates;

limiting our ability to pay cash dividends;

limiting our flexibility for, or reacting to, changes in our business or industry or economic conditions, 
thereby limiting our ability to compete with companies that are not as highly leveraged; and 

• 

increasing our vulnerability to economic downturns.

Our ability to generate sufficient cash flow from operations to make scheduled payments on our debt will depend on a 
range of economic, competitive and business factors, many of which are outside our control.  There can be no assurance that 
our business will generate sufficient cash flow from operations to make these payments.  If we are unable to meet our expenses 
and debt obligations, we may need to refinance all or a portion of our indebtedness before maturity, sell assets or issue 
additional equity.  We may not be able to refinance any of our indebtedness, sell assets or issue additional equity on 
commercially reasonable terms or at all, which could cause us to default on our obligations and impair our liquidity.  Our 
inability to generate sufficient cash flow to satisfy our debt obligations, or to refinance our debt obligations on commercially 
reasonable terms, would have a material adverse effect on our business, financial condition and results of operations, as well as 
on our ability to satisfy our debt obligations. 

Litigation and Claims—We are subject to litigation and other claims, which could cause us to incur significant 

expenses. 

We are regularly a defendant in legal proceedings relating to our present and former operations.  These include contract 
disputes, product liability claims, including ammunition and firearms, and proceedings alleging injurious exposure of plaintiffs 
to various chemicals and other substances (including proceedings based on alleged exposures to asbestos).  Frequently, the 
proceedings alleging injurious exposure involve claims made by numerous plaintiffs against many defendants.  Because of the 
inherent uncertainties of litigation, we are unable to predict the outcome of these proceedings and therefore cannot determine 
whether the financial impact, if any, will be material to our financial position, cash flows or results of operations. 

Effects of Regulation—Changes in or failure to comply with legislation or government regulations or policies could 

have a material adverse effect on our financial position or results of operations. 

Legislation or regulations that may be adopted or modified by U.S. or foreign governments, including legislation or 
regulations intended to address climate change, import and export duties and quotas, anti-dumping measures and related tariffs, 
and tax regulation could significantly affect the sales, costs and profitability of our business.  The chemical and ammunition 
industries are subject to legislative and regulatory actions, which could have a material adverse effect on our business, financial 
position or results of operations.  Existing and future government regulations and laws may reduce the demand for our products 
or impact our ability to use or manufacture certain products, which could have a material adverse effect on our business, 
financial condition and results of operations.  A material change in tax laws, treaties or regulations in the jurisdictions in which 
we operate or a change in their interpretation or application could have a material adverse effect on our business, financial 
condition and results of operations.

Environmental Costs—We have ongoing environmental costs, which could have a material adverse effect on our 

financial position or results of operations. 

Our operations and assets are subject to extensive environmental, health and safety regulations, including laws and 
regulations related to air emissions, water discharges, waste disposal and remediation of contaminated sites.  The nature of our 
operations and products, including the raw materials we handle, exposes us to the risk of liabilities, obligations or claims under 
these laws and regulations due to the production, storage, use, transportation and sale of materials that can adversely impact the 
environment or cause personal injury, including, in the case of chemicals, unintentional releases into the environment.  
Environmental laws may have a significant effect on the costs of use, transportation, handling and storage of raw materials and 
finished products, as well as the costs of storage, handling, treatment, transportation and disposal of wastes.  In addition, we are 
party to various government and private environmental actions associated with past manufacturing facilities and former waste 
disposal sites.  We have incurred, and expect to incur, significant costs and capital expenditures in complying with 
environmental laws and regulations. 

The ultimate costs and timing of environmental liabilities are difficult to predict.  Liabilities under environmental laws 

relating to contaminated sites can be imposed retroactively and on a joint and several basis.  One liable party could be held 
responsible for all costs at a site, regardless of fault, percentage of contribution to the site or the legality of the original disposal. 
We could incur significant costs, including clean-up costs, natural resource damages, civil or criminal fines and sanctions and 

19

Table of Contents

third-party lawsuits claiming, for example, personal injury and/or property damage, as a result of past or future violations of, or 
liabilities under, environmental or other laws. 

In addition, future events, such as changes to or more rigorous enforcement of environmental laws or new information 

about the extent of remediation required, could require us to make additional expenditures, modify or curtail our operations 
and/or install additional pollution control equipment.  It is possible that regulatory agencies may identify new chemicals of 
concern or enact new or more stringent clean-up standards for existing chemicals of concern.  This could lead to expenditures 
for environmental remediation in the future that are additional to existing estimates. 

Accordingly, it is possible that some of the matters in which we are involved or may become involved may be resolved 

unfavorably to us, which could materially and adversely affect our business, financial position, cash flows or results of 
operations.  See “Environmental Matters” contained in Item 7—“Management’s Discussion and Analysis of Financial 
Condition and Results of Operations.”

Ability to Attract and Retain Qualified Employees—We must attract, retain and motivate key employees, and the 

failure to do so may adversely affect our business, financial condition or results of operations. 

We feel our success depends on hiring, retaining and motivating key employees, including executive officers.  We may 

have difficulty locating and hiring qualified personnel.  In addition, we may have difficulty retaining such personnel once hired, 
and key people may leave and compete against us.  The loss of key personnel or our failure to attract and retain other qualified 
and experienced personnel could disrupt or materially adversely affect our business, financial condition or results of operations.  
In addition, our operating results could be adversely affected by increased costs due to increased competition for employees or 
higher employee turnover, which may result in the loss of significant customer business or increased costs. 

Pension Plans—The impact of declines in global equity and fixed income markets on asset values and any declines in 

interest rates and/or improvements in mortality assumptions used to value the liabilities in our pension plans may result in 
higher pension costs and the need to fund the pension plans in future years in material amounts. 

We sponsor domestic and foreign defined benefit pension plans for eligible employees and retirees.  Substantially all 

domestic defined benefit pension plan participants are no longer accruing benefits.  However, a portion of our bargaining 
hourly employees continue to participate in our domestic qualified defined benefit pension plans under a flat-benefit 
formula.  Our funding policy for the qualified defined benefit pension plans is consistent with the requirements of federal laws 
and regulations.  Our foreign subsidiaries maintain pension and other benefit plans, which are consistent with local statutory 
practices.  The determinations of pension expense and pension funding are based on a variety of rules and regulations.  Changes 
in these rules and regulations could impact the calculation of pension plan liabilities and the valuation of pension plan assets.  
They may also result in higher pension costs, additional financial statement disclosure, and the need to fund the pension plan.

At December 31, 2019, the projected benefit obligation of $2,992.0 million exceeded the market value of assets in our 
qualified defined benefit pension plans by $792.7 million, as calculated under Accounting Standards Codification (ASC) 715 
“Compensation—Retirement Benefits” (ASC 715).  During 2019, we made a discretionary cash contribution to our domestic 
qualified defined benefit pension plan of $12.5 million.  Based on our plan assumptions and estimates, we will not be required 
to make any cash contributions to the domestic qualified defined benefit pension plan at least through 2020.  

We have international qualified defined benefit pension plans to which we made cash contributions of $2.4 million, $2.6 

million and $1.7 million in 2019, 2018 and 2017, respectively, and we anticipate less than $5 million of cash contributions to 
international qualified defined benefit pension plans in 2020.  

The impact of declines in global equity and fixed income markets on asset values may result in higher pension costs and 

may increase and accelerate the need to fund the pension plans in future years.  For example, holding all other assumptions 
constant, a 100-basis point decrease or increase in the assumed long-term rate of return on plan assets for our domestic 
qualified defined benefit pension plan would have decreased or increased, respectively, the 2019 defined benefit pension plan 
income by approximately $19.8 million.  Holding all other assumptions constant for our domestic qualified defined benefit 
pension plan, a 50-basis point decrease in the discount rate used to calculate pension income for 2019 and the projected benefit 
obligation as of December 31, 2019 would have decreased pension income by $0.4 million and increased the projected benefit 
obligation by $160.0 million.  A 50-basis point increase in the discount rate used to calculate pension income for 2019 and the 
projected benefit obligation as of December 31, 2019 for our domestic qualified defined benefit pension plan would have 
increased pension income by $0.6 million and decreased the projected benefit obligation by $145.0 million.

International Sales and Operations—We are subject to risks associated with our international sales and operations 

that could have a material adverse effect on our business or results of operations.

Olin has an international presence, including the geographic regions of Europe, Asia Pacific and Latin America.  In 

2019, approximately 41% of our sales were generated outside of the United States.  These international sales and operations 
expose us to risks, including:

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

• 

difficulties and costs associated with complying with complex and varied laws, treaties, and regulations;

tariffs and trade barriers;

outbreaks of pandemic disease, such as coronavirus, which could cause us and our suppliers and/or 
customers to temporarily suspend operations in affected areas, restrict the ability of Olin to distribute our 
products or cause economic downturns that could affect demand for our products;

changes in laws and regulations, including the imposition of economic or trade sanctions affecting 
international commercial transactions;

risk of non-compliance with anti-bribery laws and regulations, such as the U.S. Foreign Corrupt Practices 
Act;

restrictions on, or difficulties and costs associated with, the repatriation of cash from foreign countries to 
the United States;

unfavorable currency fluctuations;

changes in local economic conditions;

unexpected changes in political or regulatory environments;

labor compliance and costs associated with a global workforce;

data privacy regulations;

difficulties in maintaining overseas subsidiaries and international operations; and

challenges in protecting intellectual property rights.

Any one or more of the above factors could have a material adverse effect on our business, financial condition or results 

of operations.

Asset Impairment—If our goodwill, other intangible assets or property, plant and equipment become impaired in the 

future, we may be required to record non-cash charges to earnings, which could be significant. 

The process of impairment testing for our goodwill involves a number of judgments and estimates made by management 

including future cash flows, discount rates, profitability assumptions and terminal growth rates with regards to our reporting 
units.  Our internally generated long-range plan includes cyclical assumptions regarding pricing and operating forecasts for the 
chlor alkali industry.  If the judgments and estimates used in our analysis are not realized or are affected by external factors, 
then actual results may not be consistent with these judgments and estimates, and we may be required to record a goodwill 
impairment charge in the future, which could be significant and have an adverse effect on our financial position and results of 
operations.

We review long-lived assets, including property, plant and equipment and identifiable amortizing intangible assets, for 
impairment whenever changes in circumstances or events may indicate that the carrying amounts are not recoverable.  If the 
fair value is less than the carrying amount of the asset, an impairment is recognized for the difference.  Factors which may 
cause an impairment of long-lived assets include significant changes in the manner of use of these assets, negative industry or 
market trends, a significant underperformance relative to historical or projected future operating results, extended period of 
idleness or a likely sale or disposal of the asset before the end of its estimated useful life.  If our property, plant and equipment 
and identifiable amortizing intangible assets are determined to be impaired in the future, we may be required to record non-cash 
charges to earnings during the period in which the impairment is determined, which could be significant and have an adverse 
effect on our financial position and results of operations.

Credit and Capital Market Conditions—Adverse conditions in the credit and capital markets may limit or prevent our 

ability to borrow or raise capital. 

While we believe we have facilities in place that should allow us to borrow funds as needed to meet our ordinary course 
business activities, adverse conditions in the credit and financial markets could prevent us from obtaining financing, if the need 
arises.  Our ability to invest in our businesses and refinance or repay maturing debt obligations could require access to the 
credit and capital markets and sufficient bank credit lines to support cash requirements.  If we are unable to access the credit 
and capital markets on commercially reasonable terms, we could experience a material adverse effect on our business, financial 
position or results of operations. 

Lake City Plant Contract—Various risks associated with our transition and subsequent operation of the Lake City 

Army Ammunition Plant could adversely affect our business, financial condition and results of operations. 

In 2019, our Winchester business was selected by the United States Army to operate and manage the Lake City Army 

Ammunition Plant in Independence, MO.  Our bid for this contract was developed using assumptions about the operating 
conditions of the facility and the future demand of ammunition produced from that facility.  These assumptions were based 
upon our knowledge of the facility and the market at the time of the bid as well as information that was provided to us by the 
United States Army during the solicitation process.  If our assumptions were incorrect, we may experience additional costs or 
lower revenues than expected as a result of this contract.

The Lake City Plant contract is a fixed-price contract under which we have limited ability to pass along cost overruns.

Beginning on October 1, 2019 and continuing until October 1, 2020, we are working with the incumbent contractor at 
the Lake City Plant to transition the plant to our management and control.  We have developed a transition plan that involves 
transition of the workforce, negotiation of new labor contracts, implementation of information technology and operating 
systems and start-up of manufacturing processes.  If we do not meet our timelines or otherwise fail to complete portions of our 
transition plan, we may incur additional costs or fail to meet the anticipated financial results associated with this contract.

Labor Matters—We cannot assure that we can conclude future labor contracts or any other labor agreements without 

work stoppages. 

Various labor unions represent a significant number of our hourly paid employees for collective bargaining purposes.  

The following labor contract will be required to be negotiated in 2020:

Location
Lake City Army Ammunition Plant (Winchester)

Number of Employees
1,447

Expiration Date
October 2020

While we believe our relations with our employees and their various representatives are generally satisfactory, we cannot 

assure that we can conclude any labor agreements without work stoppages and cannot assure that any work stoppages will not 
have a material adverse effect on our business, financial condition or results of operations.

Not applicable.

Item 2.  PROPERTIES

Information concerning our principal locations from which our products and services are manufactured, distributed or 

marketed are included in the tables set forth under the caption “Products and Services” contained in Item 1—“Business.”  
Generally, these facilities are well maintained, in good operating condition, and suitable and adequate for their use.  Our two 
largest facilities are co-located with Dow.  The land in which these facilities are located is leased with a 99-year initial term that 
commenced in 2015.  Additionally, we lease warehouses, terminals and distribution offices and space for executive and branch 
sales offices and service departments.  We believe our current facilities are adequate to meet the requirements of our present 
operations.

Item 3.  LEGAL PROCEEDINGS

Saltville

We have completed all work in connection with remediation of mercury contamination at the site of our former mercury 

cell chlor alkali plant in Saltville, VA required to date.  In mid-2003, the Trustees for natural resources in the North Fork 
Holston River, the Main Stem Holston River and associated floodplains, located in Smyth and Washington Counties in Virginia 
and in Sullivan and Hawkins Counties in Tennessee notified us of, and invited our participation in, an assessment of alleged 
damages to natural resources resulting from the release of mercury.  The Trustees also notified us that they had made a 
preliminary determination that we are potentially liable for natural resource damages in said rivers and floodplains.  We agreed 
to participate in the assessment.  We and the Trustees have entered into discussions concerning a resolution of this matter.  In 
light of the ongoing discussions and inherent uncertainties of the assessment, we cannot at this time determine whether the 
financial impact, if any, of this matter will be material to our financial position or results of operations.  See “Environmental 
Matters” contained in Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Other

As part of the continuing environmental investigation by federal, state and local governments of waste disposal sites, we 
have entered into a number of settlement agreements requiring us to participate in the investigation and cleanup of a number of 
sites.  Under the terms of such settlements and related agreements, we may be required to manage or perform one or more 
elements of a site cleanup, or to manage the entire remediation activity for a number of parties, and subsequently seek recovery 
of some or all of such costs from other Potentially Responsible Parties (PRPs).  In many cases, we do not know the ultimate 
costs of our settlement obligations at the time of entering into particular settlement agreements, and our liability accruals for 
our obligations under those agreements are often subject to significant management judgment on an ongoing basis.  Those cost 
accruals are provided for in accordance with generally accepted accounting principles and our accounting policies set forth in 
“Environmental Matters” contained in Item 7—“Management’s Discussion and Analysis of Financial Condition and Results of 
Operations.”

We, and our subsidiaries, are defendants in various legal actions (including proceedings based on alleged exposures to 

asbestos) incidental to our past and current business activities.  At December 31, 2019 and 2018, our consolidated balance 
sheets included liabilities for these legal actions of $12.4 million and $15.6 million, respectively.  These liabilities do not 
include costs associated with legal representation.  Based on our analysis, and considering the inherent uncertainties associated 
with litigation, we do not believe that it is reasonably possible that these legal actions will materially and adversely affect our 
financial position, cash flows or results of operations.

In connection with the October 5, 2015 acquisition of Dow’s U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics 
and Global Epoxy businesses, the prior owner of the businesses retained liabilities relating to litigation, releases of hazardous 
materials and violations of environmental law to the extent arising prior to October 5, 2015.

(1)  On April 26, 2018, our board of directors authorized a share repurchase program for the purchase of shares of common 
stock at an aggregate price of up to $500.0 million.  This program will terminate upon the purchase of $500.0 million of 
our common stock.  Through December 31, 2019, 10,072,741 shares had been repurchased at a total value of 
$195,924,171 and $304,075,829 of common stock remained available for purchase under the program.

(2)  On August 5, 2019, we entered into an accelerated share repurchase (ASR) agreement with Goldman Sachs & Co. LLC, 
a third-party financial institution, to repurchase $100.0 million of Olin’s common stock.  This authorization was granted 
under the April 26, 2018 share repurchase program and reduced the remaining authorized repurchase amount under that 
program by $100.0 million.  In connection with this agreement, we initially received 4,333,694 shares in August 2019.  
The agreement settled on October 7, 2019 at which time we received 1,414,520 additional shares which have been 
included in the October 2019 share repurchase total and resulted in a total of 5,748,214 shares repurchased under this 
ASR agreement.

Data is for the five-year period from December 31, 2014 through December 31, 2019.  The cumulative return includes 

reinvestment of dividends.  The Peer Group is weighted in accordance with market capitalization (closing stock price 
multiplied by the number of shares outstanding) as of the beginning of each of the five years covered by the performance 
graph.  We calculated the weighted return for each year by multiplying (a) the percentage that each corporation’s market 
capitalization represented of the total market capitalization for all corporations in the Peer Group for such year by (b) the total 
shareholder return for that corporation for such year.

Item 7.  MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF 

OPERATIONS

BUSINESS BACKGROUND

We are a leading vertically-integrated global manufacturer and distributor of chemical products and a leading U.S. 

manufacturer of ammunition.  Our operations are concentrated in three business segments: Chlor Alkali Products and Vinyls, 
Epoxy and Winchester.  All of our business segments are capital intensive manufacturing businesses.  Chlor Alkali Products 
and Vinyls operating rates are closely tied to the general economy.  Each segment has a commodity element to it, and therefore, 
our ability to influence pricing is quite limited on the portion of the segment’s business that is strictly commodity.  

Our Chlor Alkali Products and Vinyls segment is a commodity business where all supplier products are similar and price 

is the major supplier selection criterion.  We have little or no ability to influence prices in the large, global commodity 
markets.  Our Chlor Alkali Products and Vinyls segment produces some of the most widely used chemicals in the world that 
can be upgraded into a wide variety of downstream chemical products used in many end-markets.  Cyclical price swings, 
driven by changes in supply/demand, can be abrupt and significant and, given capacity in our Chlor Alkali Products and Vinyls 
segment, can lead to significant changes in our overall profitability.  

The Epoxy segment consumes products manufactured by the Chlor Alkali Products and Vinyls segment.  The Epoxy 

segment’s upstream and midstream products are predominately commodity markets.  We have little or no ability to influence 
prices in these large, global commodity markets.  While competitive differentiation exists through downstream customization 
and product development opportunities, pricing is extremely competitive with a broad range of competitors across the globe.  

Winchester also has a commodity element to its business, but a majority of Winchester ammunition is sold as a branded 
consumer product where there are opportunities to differentiate certain offerings through innovative new product development 
and enhanced product performance.  While competitive pricing versus other branded ammunition products is important, it is 
not the only factor in product selection.

RECENT DEVELOPMENTS AND HIGHLIGHTS

2019 Overview

Net loss was $11.3 million for the year ended December 31, 2019 compared to net income of $327.9 million for 2018.   
The decrease in results from the prior year was primarily due to lower Chlor Alkali Products and Vinyls segment results, non-
cash restructuring charges of $58.9 million, the 2018 pretax insurance recoveries of $111.0 million for environmental costs 
incurred and expensed in prior years and increased costs associated with the Information Technology Project.  In 2017, we 
began a multi-year implementation of new enterprise resource planning, manufacturing and engineering systems, and related 
infrastructure (collectively, the Information Technology Project).

On December 11, 2019, we announced that we had made the decision to permanently close a chlor alkali plant with a 

capacity of 230,000 tons and our Vinylidene Chloride (VDC) production facility, both in Freeport, TX.  These closures are 
expected to be completed before the end of 2020.  For the year ended December 31, 2019, we recorded pretax restructuring 
charges of $58.9 million for the impairment of equipment and facilities related to these actions. 

Chlor Alkali Products and Vinyls generated segment income of $336.7 million for 2019 compared to $637.1 million for 
2018.  Chlor Alkali Products and Vinyls segment income was lower than in the prior year primarily due to lower caustic soda 
pricing partially offset by lower raw material and operating costs.  The year ended December 31, 2019 also included lower 
maintenance turnaround costs.  Chlor Alkali Products and Vinyls segment income included depreciation and amortization 
expense of $470.4 million and $473.1 million in 2019 and 2018, respectively.

During 2018, North America caustic soda price contract indices increased $40 per ton while the caustic soda export price 

indices decreased approximately $270 per metric ton. During 2019, North America caustic soda price contract indices 
decreased $90 per ton and caustic soda export price indices decreased $160 per metric ton.  

Epoxy reported segment income of $53.9 million for 2019 compared to $52.8 million for 2018.  Epoxy segment income 

was higher than in the prior year primarily due to lower maintenance costs and unabsorbed fixed manufacturing costs 
associated with maintenance turnarounds and lower raw material costs, primarily benzene and propylene, substantially offset 
by lower product prices.  Epoxy segment income included depreciation and amortization expense of $100.1 million and $102.4 
million in 2019 and 2018, respectively.

Winchester reported segment income of $40.1 million for 2019 compared to $38.4 million for 2018.  Winchester 
segment income was higher than in the prior year primarily due to higher sales volumes and lower costs, primarily commodity 
and other material costs, partially offset by lower product prices.  Winchester segment income included depreciation and 
amortization expense of $20.1 million and $20.0 million in 2019 and 2018, respectively.

On January 1, 2019, we sold our 9.1% limited partnership interest in Bay Gas for $20.0 million.  The sale closed on 

February 7, 2019 which resulted in a pretax gain of approximately $11.2 million for the year ended December 31, 2019.  For 
the year ended December 31, 2018, Chlor Alkali Products and Vinyls recorded a $21.5 million non-cash impairment charge 
related to an adjustment to the value of our interest in Bay Gas.

On July 16, 2019, Olin issued $750.0 million aggregate principal amount of 5.625% senior notes due August 1, 2029 

(2029 Notes), which were registered under the Securities Act of 1933, as amended.  Proceeds from the 2029 Notes were used to 
redeem the remaining balance of the $1,375.0 million Term Loan Facility of $493.0 million and $150.0 million of the 
Receivables Financing Agreement.

On July 16, 2019, Olin also entered into a new five-year, $2,000.0 million senior credit facility (2019 Senior Credit 
Facility), which replaces the existing $1,975.0 million senior credit facility.  The 2019 Senior Credit Facility will mature in July 
2024.  In December 2019, Olin amended the 2019 Senior Credit Facility which amended the restrictive covenants of the 
agreement, including expanding the coverage and leverage ratios to be less restrictive over the next two and a half years.  The 
2019 Senior Credit Facility includes a senior unsecured delayed-draw term loan facility in an aggregate principal amount of up 
to $1,200.0 million (Delayed Draw Term Loan Facility) and an $800.0 million senior unsecured revolving credit facility (2019 
Senior Revolving Credit Facility).  The Delayed Draw Term Loan Facility will be available on a delayed basis in up to three 
draws to be made on or prior to November 29, 2020.  We expect the proceeds from the Delayed Draw Term Loan Facility will 
be used to redeem the 9.75% senior notes due 2023 and the 10.00% senior notes due 2025 on or about October 15, 2020.  

On September 27, 2019, Winchester was notified that it had been selected by the United States Army to operate and 

manage the Lake City Plant in Independence, MO.  Following a one-year transition period, Winchester will assume full 
operational control of the Lake City Plant on October 1, 2020.  The contract has an initial term of seven years and may be 
extended by the United States Army for up to three additional years.  The contract is expected to increase Winchester’s annual 
revenue by $450 million to $550 million.

Sales for 2019 were $6,110.0 million compared to $6,946.1 million in 2018, a decrease of $836.1 million, or 12%.  Chlor 

Alkali Products and Vinyls sales decreased by $566.6 million primarily due to lower caustic soda pricing.  Epoxy sales 
decreased by $278.7 million primarily due to lower product prices and an unfavorable effect of foreign currency translation.  
Winchester sales increased by $9.2 million primarily due to higher ammunition sales to commercial customers.

Gross margin decreased $453.2 million, or 40%, from 2018.  Chlor Alkali Products and Vinyls gross margin decreased 

by $342.1 million, primarily due to lower caustic soda pricing, partially offset by lower raw material and operating costs.  
Epoxy gross margin decreased $20.6 million primarily due to lower product prices, partially offset by lower raw material costs, 
primarily benzene and propylene, and lower maintenance and unabsorbed fixed manufacturing costs associated with 
maintenance turnarounds.  Winchester gross margin increased $1.2 million primarily due to lower costs, partially offset by 
lower product prices.  Gross margin in 2018 was positively impacted by insurance recoveries for environmental costs incurred 
and expensed in prior periods of $111.0 million.  Gross margin as a percentage of sales decreased to 11% in 2019 from 16% in 
2018.

Selling and administration expenses in 2019 decreased $13.7 million, or 3%, from 2018.  The years ended December 31, 

2019 and 2018 included costs associated with the Information Technology Project of $77.0 million and $36.5 million, 
respectively, an increase of $40.5 million.  More than offsetting this increase were lower legal and legal-related settlement 
expenses of $19.3 million, primarily due to the legal fees associated with the environmental recovery actions in 2018, lower 
consulting and contract services of $13.7 million, lower management incentive compensation expense of $10.2 million, which 
includes mark-to-market adjustments on stock-based compensation expense, and a favorable foreign currency impact of $8.5 
million.  Selling and administration expenses as a percentage of sales were 7% in 2019 and 6% in 2018.

Restructuring charges in 2019 included $58.9 million of non-cash impairment charges for equipment and facilities  
associated with the closure of a chlor alkali plant and a VDC production facility, both in Freeport, TX.  Restructuring charges in 
2019 and 2018 were also associated with the March 2016 closure of 433,000 tons of chlor alkali capacity across three separate 
locations and the December 2018 decision to permanently close the ammunition assembly operations at our Winchester facility 
in Geelong, Australia.

Other operating income for the year ended December 31, 2018 included an $8.0 million insurance recovery for a second 
quarter 2017 business interruption at our Freeport, TX vinyl chloride monomer facility partially offset by a $1.7 million loss on 
the sale of land. 

Earnings (losses) of non-consolidated affiliates for the year ended December 31, 2018 reflect a $21.5 million non-cash 

impairment charge.  

Interest expense for the year ended December 31, 2019 was impacted by a lower level of average debt outstanding 

partially offset by higher interest rates compared to the year ended December 31, 2018.  Interest expense for the years ended 
December 31, 2019 and 2018 included $17.0 million and $16.0 million, respectively, of accretion expense related to the 
ethylene payment discount expected to be paid on or about the fourth quarter of 2020.  Interest expense was reduced by 
capitalized interest of $10.8 million and $6.0 million for 2019 and 2018, respectively. 

Non-operating pension income includes all components of pension and other postretirement income (costs) other than 

service costs.  Non-operating pension income was lower for the year ended December 31, 2019, primarily due to an increase in 
Pension Benefit Guaranty Corporation fees associated with our domestic qualified defined benefit pension plan.

The effective tax rate for 2019 included benefits associated with the finalization of the Internal Revenue Service (IRS) 

review of years 2013 to 2015 U.S. income tax claims, stock-based compensation, prior year tax positions, foreign tax law 
changes, a remeasurement of deferred taxes due to a decrease in our state effective tax rates and a change in tax contingencies.  
The effective tax rate also included expenses associated with a net increase in the valuation allowance primarily related to 
foreign deferred tax assets and liabilities.  These factors resulted in a net $19.4 million tax benefit.  After giving consideration 
to these items, the effective tax rate for 2019 of 16.8% was lower than the 21% U.S. federal statutory rate primarily due to state 
taxes and a net increase in the valuation allowance related to losses in foreign jurisdictions, partially offset by foreign income 
taxes and favorable permanent salt depletion deductions.  The effective tax rate for 2018 included benefits associated with the 
U.S. Tax Cuts & Jobs Act (2017 Tax Act), stock-based compensation, changes in tax contingencies, a foreign dividend 
payment, changes associated with prior year tax positions and the remeasurement of deferred taxes due to a decrease in our 
state effective tax rates.  The effective tax rate also included expenses associated with a net increase in the valuation allowance 
related to deferred tax assets in foreign jurisdictions and the remeasurement of deferred taxes due to changes in our foreign tax 
rates.  These factors resulted in a net $2.9 million tax benefit, of which $3.8 million related to the increase of the 2017 Tax Act 
benefit.  After giving consideration to these items, the effective tax rate for 2018 of 25.7% was higher than the 21% U.S. federal 
statutory rate primarily due to state and foreign income taxes, foreign income inclusions and a net increase in the valuation 
allowance related to current year losses in foreign jurisdictions, partially offset by favorable permanent salt depletion 
deductions. 

2018 Compared to 2017 

Sales for 2018 were $6,946.1 million compared to $6,268.4 million in 2017, an increase of $677.7 million, or 
11%.  Chlor Alkali Products and Vinyls sales increased by $485.9 million primarily due to increased pricing for caustic soda, 
EDC, chlorine and other chlorine-derivatives, partially offset by lower caustic soda volumes and a less favorable product mix.  
Epoxy sales increased by $216.7 million primarily due to higher product prices, partially offset by lower volumes and a less 
favorable product mix.  Winchester sales decreased by $24.9 million primarily due to lower sales to commercial customers, 
partially offset by higher sales to military customers and law enforcement agencies.

Gross margin increased $410.5 million, or 58%, from 2017.  Gross margin was positively impacted by insurance 
recoveries for environmental costs incurred and expensed in prior periods of $111.0 million.  Chlor Alkali Products and Vinyls 
gross margin increased by $263.8 million, primarily due to higher product pricing partially offset by increased costs, lower 
caustic soda volumes and a less favorable product mix.  Epoxy gross margin increased $78.3 million primarily due to higher 
product prices partially offset by increased raw material costs, primarily benzene and propylene.  Epoxy gross margin was also 
negatively impacted by the cost of an approximately two-month planned maintenance turnaround at our production facilities in 
Freeport, TX, which also reduced volumes.  Both Chlor Alkali Products and Vinyls and Epoxy 2017 gross margins were 
negatively impacted by incremental costs to continue operations and unabsorbed fixed manufacturing costs associated with 
Hurricane Harvey.  Winchester gross margin decreased $34.0 million primarily due to increased commodity and other material 
costs, lower commercial sales volumes and a less favorable product mix and lower selling prices.  Gross margin as a percentage 
of sales increased to 16% in 2018 from 11% in 2017.

Table of Contents

Selling and administration expenses in 2018 increased $60.8 million, or 16%, from 2017.  The increase was primarily 

due to higher costs associated with the Information Technology Project of $31.2 million, higher legal and legal-related 
settlement expenses of $15.6 million, primarily associated with environmental recovery actions, increased incentive 
compensation expense of $11.6 million, an unfavorable foreign currency impact of $10.9 million and higher consulting and 
contract services of $10.4 million, which include transition service fees from Dow.  These increased costs were partially offset 
by lower stock-based compensation expense of $15.0 million, which includes mark-to-market adjustments.  Selling and 
administration expenses as a percentage of sales were 6% in both 2018 and 2017.

Restructuring charges in 2018 and 2017 were primarily associated with the March 2016 closure of 433,000 tons of chlor 

alkali capacity across three separate locations.  Restructuring charges in 2018 were also associated with a December 2018 
decision to permanently close the ammunition assembly operations at our Winchester facility in Geelong, Australia. 

Acquisition-related costs for the years ended December 31, 2018 and 2017 were related to the integration of the 

Acquired Business, and consisted of advisory, legal, accounting and other professional fees.

Other operating income for the year ended December 31, 2018 included an $8.0 million insurance recovery for a second 
quarter 2017 business interruption at our Freeport, TX vinyl chloride monomer facility partially offset by a $1.7 million loss on 
the sale of land.  Other operating income for the year ended December 31, 2017 included a gain of $3.3 million from the sale of 
a former manufacturing facility. 

Earnings (losses) of non-consolidated affiliates decreased by $21.5 million for the year ended December 31, 2018, which 

reflect a $21.5 million non-cash impairment charge recorded during 2018.

Interest expense increased by $25.8 million for the year ended December 31, 2018 primarily due to higher interest rates 
and an increase of $12.1 million of accretion expense related to the ethylene payment discount expected to be paid on or about 
the fourth quarter of 2020, partially offset by a lower level of debt outstanding for the year ended December 31, 2018 compared 
to 2017.

Non-operating pension income includes all components of pension and other postretirement income (costs) other than 

service costs.  Non-operating pension income was lower for the year ended December 31, 2018, primarily due to an increase in 
the amortization of actuarial losses and higher Pension Benefit Guaranty Corporation fees associated with our domestic 
qualified defined benefit pension plan.

The effective tax rate for 2018 included benefits associated with the 2017 Tax Act, stock-based compensation, changes in 

tax contingencies, a foreign dividend payment, changes associated with prior year tax positions and the remeasurement of 
deferred taxes due to a decrease in our state effective tax rates.  The effective tax rate also included expenses associated with a 
net increase in the valuation allowance related to deferred tax assets in foreign jurisdictions and the remeasurement of deferred 
taxes due to changes in our foreign tax rates.  These factors resulted in a net $2.9 million tax benefit, of which $3.8 million 
related to the increase of the 2017 Tax Act benefit.  After giving consideration to these items, the effective tax rate for 2018 of 
25.7% was higher than the 21% U.S. federal statutory rate primarily due to state and foreign income taxes, foreign income 
inclusions and a net increase in the valuation allowance related to current year losses in foreign jurisdictions, partially offset by 
favorable permanent salt depletion deductions.  The effective tax rate for 2017 included benefits associated with the 2017 Tax 
Act, an agreement with the Internal Revenue Service on prior period tax examinations, stock based compensation, U.S. federal 
tax credits, changes to prior year tax positions and a reduction to the deferred tax liability on unremitted foreign earnings.  The 
effective tax rate also included an expense associated with a net increase in the valuation allowance, primarily related to foreign 
net operating losses and remeasurement of deferred taxes due to an increase in our state effective tax rates.  These factors 
resulted in a net $452.3 million tax benefit, of which $437.9 million was a provisional benefit from the 2017 Tax Act.  After 
giving consideration to these items, the effective tax rate for 2017 of 17.1% was lower than the 35% U.S. federal statutory rate, 
primarily due to favorable permanent salt depletion deductions.

SEGMENT RESULTS

We define segment results as income (loss) before interest expense, interest income, other operating income (expense), 

non-operating pension income, other income (expense) and income taxes, and includes the operating results of non-
consolidated affiliates.  Consistent with the guidance in ASC 280 “Segment Reporting,” we have determined it is appropriate to 
include the operating results of non-consolidated affiliates in the relevant segment financial results.  We have three operating 
segments: Chlor Alkali Products and Vinyls, Epoxy and Winchester.  The three operating segments reflect the organization used 
by our management for purposes of allocating resources and assessing performance.  Chlorine used in our Epoxy segment is 
transferred at cost from the Chlor Alkali Products and Vinyls segment.  Sales and profits are recognized in the Chlor Alkali 
Products and Vinyls segment for all caustic soda generated and sold by Olin.

2019 Compared to 2018

Chlor Alkali Products and Vinyls

Chlor Alkali Products and Vinyls sales for 2019 were $3,420.1 million compared to $3,986.7 million for 2018, a 
decrease of $566.6 million, or 14%.  The sales decrease was primarily due to lower product pricing, primarily caustic soda, and 
lower volumes.

Chlor Alkali Products and Vinyls generated segment income of $336.7 million for 2019 compared to $637.1 million for 
2018, a decrease of $300.4 million, or 47%.  The decrease in Chlor Alkali Products and Vinyls segment income was primarily 
due to lower product prices ($449.4 million), primarily caustic soda, and lower volumes ($53.0 million), partially offset by 
lower raw material and operating costs ($138.1 million) and lower maintenance turnaround costs ($42.4 million).  Chlor Alkali 
Products and Vinyls 2018 segment income was also negatively impacted by a non-cash impairment charge associated with our 
investment in a non-consolidated affiliate ($21.5 million).  Chlor Alkali Products and Vinyls segment income included 
depreciation and amortization expense of $470.4 million and $473.1 million in 2019 and 2018, respectively.

2018 Compared to 2017 

Chlor Alkali Products and Vinyls sales for 2018 were $3,986.7 million compared to $3,500.8 million for 2017, an 
increase of $485.9 million, or 14%.  The sales increase was primarily due to increased caustic soda, EDC, chlorine and other 
chlorine-derivatives pricing.  The higher product prices were partially offset by lower caustic soda volumes and a less favorable 
product mix.  Chlor Alkali Products and Vinyls 2017 sales volumes were negatively impacted by lost sales associated with 
Hurricane Harvey.

Chlor Alkali Products and Vinyls generated segment income of $637.1 million for 2018 compared to $405.8 million for 
2017, an increase of $231.3 million, or 57%. The increase in Chlor Alkali Products and Vinyls segment income was primarily 
due to higher product prices ($502.9 million) and lower ethylene costs associated with the acquisition of additional cost-based 
ethylene from Dow in late September 2017, partially offset by higher ethane prices ($8.0 million).  Partially offsetting these 
benefits were higher raw material and freight costs ($147.5 million), lower volumes, primarily caustic soda, and a less 
favorable product mix ($71.1 million), increased depreciation and amortization expense ($40.9 million) and increased operating 
costs ($25.6 million), primarily maintenance to improve reliability.  Chlor Alkali Products and Vinyls 2018 segment income 
was also negatively impacted by a non-cash impairment charge associated with our investment in a non-consolidated affiliate 
($21.5 million).  Chlor Alkali Products and Vinyls 2017 segment income was negatively impacted by incremental costs to 
continue operations and unabsorbed fixed manufacturing costs associated with Hurricane Harvey ($27.0 million).  Chlor Alkali 
Products and Vinyls segment income included depreciation and amortization expense of $473.1 million and $432.2 million in 
2018 and 2017, respectively.

2019 Compared to 2018 

Epoxy

Epoxy sales were $2,024.4 million for 2019 compared to $2,303.1 million for 2018, a decrease of $278.7 million, or 

12%.  The sales decrease was primarily due to lower product prices ($258.9 million) and an unfavorable effect of foreign 
currency translation ($62.5 million), partially offset by increased volumes ($42.7 million).

Epoxy reported segment income of $53.9 million for 2019 compared to $52.8 million for 2018, an increase of $1.1 

million, or 2%.  The increase in segment income was primarily due to lower maintenance costs and unabsorbed fixed 
manufacturing costs associated with maintenance turnarounds ($40.0 million), decreased operating costs ($18.1 million) and 
lower raw material costs ($214.1 million), primarily benzene and propylene, partially offset by lower product prices ($258.9 
million) and an unfavorable product mix ($12.2 million).  A significant percentage of our Euro denominated sales are of 
products manufactured within Europe.  As a result, the impact of foreign currency translation on revenue is primarily offset by 
the impact of foreign currency translation on raw materials and manufacturing costs also denominated in Euros.  Epoxy 
segment results included depreciation and amortization expense of $100.1 million and $102.4 million in 2019 and 2018, 
respectively.

2018 Compared to 2017 

Epoxy sales were $2,303.1 million for 2018 compared to $2,086.4 million for 2017, an increase of $216.7 million, or 

10%.  The sales increase was primarily due to higher product prices ($322.4 million) and a favorable effect of foreign currency 
translation ($48.2 million), partially offset by lower volumes ($153.9 million).  Epoxy 2018 sales volumes were negatively 
impacted by lost sales associated with planned maintenance turnarounds, while 2017 Epoxy sales volumes were negatively 
impacted by Hurricane Harvey.

Epoxy reported segment income of $52.8 million for 2018 compared to a segment loss of $11.8 million for 2017, an 

increase of $64.6 million.  The increase in Epoxy segment results was primarily due to higher product prices ($322.4 million) 
partially offset by higher raw material costs ($190.8 million), primarily benzene and propylene.  Epoxy results were also 
negatively impacted by lower volumes and a less favorable product mix ($42.2 million), higher maintenance costs and 
unabsorbed fixed manufacturing costs associated with turnarounds and outages ($23.1 million), increased operating costs, 
including utilities ($21.3 million) and higher depreciation and amortization expense ($8.1 million).  Additionally, Epoxy 2017 
segment results were negatively impacted by incremental costs to continue operations and unabsorbed fixed manufacturing 
costs associated with Hurricane Harvey ($27.7 million).  Epoxy segment results included depreciation and amortization 
expense of $102.4 million and $94.3 million in 2018 and 2017, respectively.

2019 Compared to 2018 

Winchester

Winchester sales were $665.5 million for 2019 compared to $656.3 million for 2018, an increase of $9.2 million, or 
1%.  The sales increase was primarily due to higher ammunition sales to commercial customers ($13.7 million), partially offset 
by decreased sales to military customers and law enforcement agencies ($4.5 million).

Table of Contents

Winchester reported segment income of $40.1 million for 2019 compared to $38.4 million for 2018, an increase of $1.7 

million, or 4%.  The increase in segment income was primarily due to lower costs ($8.7 million), primarily commodity and 
other material costs, partially offset by lower product prices ($6.6 million) and a less favorable product mix ($0.4 million). 
Winchester segment income included depreciation and amortization expense of $20.1 million and $20.0 million in 2019 and 
2018, respectively.

2018 Compared to 2017 

Winchester sales were $656.3 million for 2018 compared to $681.2 million for 2017, a decrease of $24.9 million, or 

4%.  The sales decrease was primarily due to lower ammunition sales to commercial customers ($43.4 million), partially offset 
by higher sales to military customers and law enforcement agencies ($18.5 million).

Winchester reported segment income of $38.4 million for 2018 compared to $72.4 million for 2017, a decrease of $34.0 
million, or 47%.  The decrease in segment income was due to higher commodity and other material costs ($19.6 million), lower 
commercial sales volumes and a less favorable product mix ($9.4 million) and lower product prices ($8.0 million).  These 
decreases were partially offset by lower operating costs ($3.0 million), including depreciation and amortization expense.  
Winchester segment income included depreciation and amortization expense of $20.0 million and $19.5 million in 2018 and 
2017, respectively.

2019 Compared to 2018

Corporate/Other

For the year ended December 31, 2019, net charges to income for environmental investigatory and remedial activities 

were $20.5 million, which include $4.8 million of an environmental insurance-related settlement gain.  For the year ended 
December 31, 2018, net credits to income for environmental investigatory and remedial activities were $103.7 million, which 
include $111.0 million of insurance recoveries for environmental costs incurred and expensed in prior periods.  Without these 
recoveries, charges to income for environmental investigatory and remedial activities in 2019 and 2018 would have been $25.3 
million and $7.3 million, respectively.  The increase in environmental expense from the prior year primarily relates to a $20.0 
million increase in costs at a former manufacturing site resulting from revised remediation estimates as a result of agency 
action.  These charges related primarily to expected future investigatory and remedial activities associated with past 
manufacturing operations and former waste disposal sites.

For 2019, other corporate and unallocated costs were $156.3 million compared to $158.3 million for 2018, a decrease of 

$2.0 million, or 1%.  The decrease was primarily due to lower legal and legal-related settlement expenses of $17.7 million, 
primarily due to the legal fees associated with the environmental recovery actions in 2018, decreased management incentive 
expense of $9.4 million, which includes mark-to-market adjustments on stock-based compensation expense, a favorable foreign 
currency impact of $8.2 million and lower consulting charges of $6.4 million.  These decreases were partially offset by higher 
costs associated with the Information Technology Project of $40.5 million.

2018 Compared to 2017 

Net credits to income for environmental investigatory and remedial activities were $103.7 million for 2018, which 

include $111.0 million of insurance recoveries for environmental costs incurred and expensed in prior periods. Without these 
recoveries, charges to income for environmental investigatory and remedial activities would have been $7.3 million for the year 
ended December 31, 2018 compared with $8.5 million for the year ended December 31, 2017.  These charges related primarily 
to expected future investigatory and remedial activities associated with past manufacturing operations and former waste 
disposal sites.

For 2018, other corporate and unallocated costs were $158.3 million compared to $112.4 million for 2017, an increase of 

$45.9 million, or 41%.  The increase was primarily due to higher costs associated with the Information Technology Project of 
$31.2 million, higher legal and legal-related settlement expenses of $18.0 million and an unfavorable foreign currency impact 
of $10.6 million.  The increases were partially offset by lower stock-based compensation expense of $15.0 million, which 
includes mark-to-market adjustments.  The higher legal and legal-related settlement expenses were primarily due to legal fees 
associated with environmental recovery actions.

Restructurings

On December 11, 2019, we announced that we had made the decision to permanently close a chlor alkali plant with a 

capacity of 230,000 tons and our VDC production facility, both in Freeport, TX.  These closures are expected to be completed 
before the end of 2020.  For the year ended December 31, 2019, we recorded pretax restructuring charges of $58.9 million for 
non-cash impairment of equipment and facilities related to these actions. 

On December 10, 2018, we announced that we had made the decision to permanently close the ammunition assembly 

operations at our Winchester facility in Geelong, Australia.  Subsequent to the facility’s closure, products for customers in the 
region are sourced from Winchester manufacturing facilities located in the United States.  For the years ended December 31, 
2019 and 2018, we recorded pretax restructuring charges of $0.4 million and $4.1 million, respectively for the write-off of 
equipment and facility costs, employee severance and related benefit costs and lease and other contract termination costs 
related to this action.

2020 OUTLOOK

Olin continues to face a challenging pricing environment as we enter 2020 within our chemicals businesses.  In 2019, the 

Chlor Alkali Products and Vinyls business experienced weaker demand from urethane, agricultural, refrigerant, alumina, and 
pulp and paper customers.  The Epoxy business also has experienced weaker product demand from automotive, electrical 
laminate, and industrial coatings customers throughout 2019.  The lower demand environment put downward pressure on 
pricing in both chemical businesses.  We expect the weak underlying demand and pricing fundamentals in our chemical 
businesses to persist through at least first quarter 2020.  We expect lower raw material costs in both our Chlor Alkali Products 
and Vinyls and Epoxy segments in 2020 compared to 2019 to partially offset the pricing impact of lower demand.  

We expect our Winchester segment to benefit from the Lake City U.S. Army Ammunition Plant contract beginning in the 

fourth quarter of 2020.  We expect to incur approximately $25 million in transition costs and $80 million associated with an 
initial working capital investment in 2020 for the Lake City Plant contract.  The contract is expected to increase Winchester’s 
annual revenue by $450 million to $550 million.

Other Corporate and Unallocated costs in 2020 are expected to be higher than the $156.3 million in 2019, primarily due 
to higher management incentive expense, including mark-to-market adjustments on stock-based compensation expense.  Costs 
associated with the Information Technology Project in 2020 are expected to be comparable to 2019.  The Information 
Technology Project will be substantially completed during 2020.  

During 2020, we anticipate environmental expenses in the $25 million to $30 million range compared to $25.3 million, 

excluding the $4.8 million of insurance recoveries, in 2019.  We do not believe that there will be additional recoveries of 
environmental costs incurred and expensed in prior periods during 2020.

We expect non-operating pension income in 2020 to be in the $13 million to $18 million range compared to $16.3 
million in 2019.  Based on our plan assumptions and estimates, we will not be required to make any cash contributions to our 
domestic qualified defined benefit pension plan in 2020.  We have several international qualified defined benefit pension plans 
for which we anticipate cash contributions of less than $5 million in 2020.

In 2020, we currently expect our capital spending to be in the $250 million to $300 million range, including the 
investment associated with the Information Technology Project of approximately $40 million.  We expect 2020 depreciation 
and amortization expense to be in the $550 million to $575 million range.

We currently believe the 2020 effective tax rate will be in the 27% to 33% range, while we expect cash taxes will be in 

the range of $30 million to $40 million, which primarily relates to earnings in foreign jurisdictions.

PENSION AND POSTRETIREMENT BENEFITS

Under ASC 715, we recorded an after-tax charge of $150.2 million ($183.9 million pretax) to shareholders’ equity as of 
December 31, 2019 for our pension and other postretirement plans.  This charge primarily reflected a 100-basis point decrease 
in the domestic pension plans’ discount rate, partially offset by favorable performance on plan assets during 2019.  In 2018, we 
recorded an after-tax charge of $74.9 million ($98.5 million pretax) to shareholders’ equity as of December 31, 2018 for our 
pension and other postretirement plans.  This charge primarily reflected unfavorable performance on plan assets during 2018, 
partially offset by a 60-basis point increase in the domestic pension plans’ discount rate.  In 2017, we recorded an after-tax 
charge of $21.6 million ($27.3 million pretax) to shareholders’ equity as of December 31, 2017 for our pension and other 
postretirement plans.  This charge primarily reflected a 50-basis point decrease in the domestic pension plans’ discount rate, 
partially offset by favorable performance on plan assets during 2017.  These non-cash charges to shareholders’ equity do not 
affect our ability to borrow under our senior credit facility. 

During 2019, we made a discretionary cash contribution to our domestic qualified defined benefit pension plan of $12.5 
million.  Based on our plan assumptions and estimates, we will not be required to make any cash contributions to the domestic 
qualified defined benefit pension plan at least through 2020.  

In connection with international qualified defined benefit pension plans, we made cash contributions of $2.4 million, 

$2.6 million and $1.7 million in 2019, 2018 and 2017, respectively, and we anticipate less than $5 million of cash contributions 
to international qualified defined benefit pension plans in 2020.  

At December 31, 2019, the projected benefit obligation of $2,992.0 million exceeded the market value of assets in our 

qualified defined benefit pension plans by $792.7 million, as calculated under ASC 715.

Cash outlays for remedial and investigatory activities associated with former waste sites and past operations were not 
charged to income but instead were charged to reserves established for such costs identified and expensed to income in prior 
years.  Cash outlays for normal plant operations for the disposal of waste and the operation and maintenance of pollution 
control equipment and facilities to ensure compliance with mandated and voluntarily imposed environmental quality standards 
were charged to income.

Total environmental-related cash outlays for 2020 are estimated to be approximately $210 million, of which 

approximately $17 million is expected to be spent on investigatory and remedial efforts, approximately $3 million on capital 
projects and approximately $190 million on normal plant operations.  Remedial and investigatory spending is anticipated to be 
higher in 2020 than 2019 due to the timing of continuing remedial action plans and investigations.  Historically, we have 
funded our environmental capital expenditures through cash flow from operations and expect to do so in the future.

Table of Contents

Annual environmental-related cash outlays for site investigation and remediation, capital projects and normal plant 

operations are expected to range between $200 million to $220 million over the next several years, $15 million to $25 million 
of which is for investigatory and remedial efforts, which are expected to be charged against reserves recorded on our 
consolidated balance sheet.  While we do not anticipate a material increase in the projected annual level of our environmental-
related cash outlays for site investigation and remediation, there is always the possibility that such an increase may occur in the 
future in view of the uncertainties associated with environmental exposures.

As is common in our industry, we are subject to environmental laws and regulations related to the use, storage, handling, 

generation, transportation, emission, discharge, disposal and remediation of, and exposure to, hazardous and non-hazardous 
substances and wastes in all of the countries in which we do business.  

The establishment and implementation of national, state or provincial and local standards to regulate air, water and land 

quality affect substantially all of our manufacturing locations around the world.  Laws providing for regulation of the 
manufacture, transportation, use and disposal of hazardous and toxic substances, and remediation of contaminated sites, have 
imposed additional regulatory requirements on industry, particularly the chemicals industry.  In addition, implementation of 
environmental laws has required and will continue to require new capital expenditures and will increase plant operating 
costs.  We employ waste minimization and pollution prevention programs at our manufacturing sites.

In connection with the October 5, 2015 acquisition of Dow’s U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics 
and Global Epoxy businesses, the prior owner of the businesses retained liabilities relating to releases of hazardous materials 
and violations of environmental law to the extent arising prior to October 5, 2015.

We are party to various government and private environmental actions associated with past manufacturing facilities and 

former waste disposal sites.  Associated costs of investigatory and remedial activities are provided for in accordance with 
generally accepted accounting principles governing probability and the ability to reasonably estimate future costs.  Our ability 
to estimate future costs depends on whether our investigatory and remedial activities are in preliminary or advanced 
stages.  With respect to unasserted claims, we accrue liabilities for costs that, in our experience, we expect to incur to protect 
our interests against those unasserted claims.  Our accrued liabilities for unasserted claims amounted to $8.6 million at 
December 31, 2019.  With respect to asserted claims, we accrue liabilities based on remedial investigation, feasibility study, 
remedial action and operation, maintenance and monitoring (OM&M) expenses that, in our experience, we expect to incur in 
connection with the asserted claims.  Required site OM&M expenses are estimated and accrued in their entirety for required 
periods not exceeding 30 years, which reasonably approximates the typical duration of long-term site OM&M. 

Environmental provisions charged (credited) to income, which are included in cost of goods sold, were as follows:

Provisions charged to income for the year ended December 31, 2019 include a $20.0 million increase in costs at a former 
manufacturing site resulting from revised remediation estimates as a result of agency action during the second quarter of 2019.  

During 2018, we settled certain disputes with respect to insurance coverage for costs at various environmental 
remediation sites for $121.0 million.  Environmental expense (income) for the year ended December 31, 2018 include 
insurance recoveries for environmental costs incurred and expensed in prior periods of $111.0 million.  The recoveries are 
reduced by estimated liabilities of $10.0 million associated with claims by subsequent owners of certain of the settled 
environmental sites.  Environmental expense (income) for the year ended December 31, 2019 included $4.8 million of 
recoveries associated with resolving the outstanding third party claims against the proceeds from the 2018 environmental 
insurance settlement.  

Our total estimated environmental liability at the end of 2019 was attributable to 59 sites, 14 of which were United 
States Environmental Protection Agency National Priority List sites.  Nine sites accounted for 81% of our environmental 
liability and, of the remaining 50 sites, no one site accounted for more than 3% of our environmental liability.  At seven of the 
nine sites, part of the site is in the long-term OM&M stage.  At six of the nine sites, a remedial action plan is being developed 
for part of the site.  At five of the nine sites, a remedial design is being developed at part of the site and at four of the nine sites, 
part of the site is subject to a remedial investigation.  All nine sites are either associated with past manufacturing operations or 
former waste disposal sites.  None of the nine largest sites represents more than 20% of the liabilities reserved on our 
consolidated balance sheet at December 31, 2019 for future environmental expenditures.

Our consolidated balance sheets included liabilities for future environmental expenditures to investigate and remediate 
known sites amounting to $139.0 million at December 31, 2019, and $125.6 million at December 31, 2018, of which $122.0 
million and $108.6 million, respectively, were classified as other noncurrent liabilities.  Our environmental liability amounts do 
not take into account any discounting of future expenditures or any consideration of insurance recoveries or advances in 
technology.  These liabilities are reassessed periodically to determine if environmental circumstances have changed and/or 
remediation efforts and our estimate of related costs have changed.  As a result of these reassessments, future charges to income 
may be made for additional liabilities.  Of the $139.0 million included on our consolidated balance sheet at December 31, 2019 
for future environmental expenditures, we currently expect to utilize $87.3 million of the reserve for future environmental 
expenditures over the next 5 years, $20.5 million for expenditures 6 to 10 years in the future, and $31.2 million for 
expenditures beyond 10 years in the future.  These estimates are subject to a number of risks and uncertainties, as described in 
“Environmental Costs” contained in Item 1A—“Risk Factors.”

Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, 
developments at sites resulting from investigatory studies, advances in technology, changes in environmental laws and 
regulations and their application, changes in regulatory authorities, the scarcity of reliable data pertaining to identified sites, the 
difficulty in assessing the involvement and financial capability of other PRPs, our ability to obtain contributions from other 
parties and the lengthy time periods over which site remediation occurs.  It is possible that some of these matters (the outcomes 
of which are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our 
financial position or results of operations.  At December 31, 2019, we estimate it is reasonably possible that we may have 
additional contingent environmental liabilities of $80 million in addition to the amounts for which we have already recorded as 
a reserve.

LEGAL MATTERS AND CONTINGENCIES

We are party to a dispute relating to a contract at our Plaquemine, LA facility.  The other party to the contract filed a 

demand for arbitration alleging, among other things, that Olin breached the contract, and claims damages in excess of the 
amount Olin believes it is obligated to pay under the contract.  Olin asserted a counterclaim alleging it has been charged a fee in 
excess of what the contract permits.  The arbitration hearing was held during the fourth quarter 2019.  Although the timing is 
uncertain, we currently anticipate receiving a ruling during the first half of 2020.  Any additional losses related to this contract 
dispute are not currently estimable because of unresolved questions of fact and law but, if resolved unfavorably to Olin, they 
could have a material adverse effect on our financial position, cash flows or results of operations.

Olin and Oxy Vinyls, L.P. (Oxy) have a long-term chlorine supply agreement, which is the subject of a pricing dispute.  
The dispute is pending in the United States District Court for the Southern District of Texas.  Although the timing is uncertain, 
we currently anticipate that the case will proceed to trial during 2020.  Any additional losses related to this contract dispute are 
not currently estimable because of unresolved questions of fact and law but, if resolved unfavorably to Olin, they could have a 
material adverse effect on our financial position, cash flows or results of operations.

Olin, K.A. Steel Chemicals (a wholly owned subsidiary of Olin) and other caustic soda producers were named as 
defendants in six purported class action civil lawsuits filed March 22, 25 and 26, 2019 and April 12, 2019 in the U.S. District 
Court for the Western District of New York on behalf of the respective named plaintiffs and a putative class comprised of all 
persons and entities who purchased caustic soda in the U.S. directly from one or more of the defendants, their parents, 
predecessors, subsidiaries or affiliates at any time between October 1, 2015 and the present.  Olin, K.A. Steel Chemicals and 
other caustic soda producers were also named as defendants in two purported class action civil lawsuits filed July 25 and 29, 
2019 in the U.S. District Court for the Western District of New York on behalf of the respective named plaintiffs and a putative 
class comprised of all persons and entities who purchased caustic soda in the U.S. indirectly from distributors at any time 
between October 1, 2015 and the present.  The other defendants named in the lawsuits are Occidental Petroleum Corporation, 
Occidental Chemical Corporation d/b/a OxyChem, Westlake Chemical Corporation, Shin-Etsu Chemical Co., Ltd., Shintech 
Incorporated, Formosa Plastics Corporation, and Formosa Plastics Corporation, U.S.A. The lawsuits allege the defendants 
conspired to fix, raise, maintain and stabilize the price of caustic soda, restrict domestic (U.S.) supply of caustic soda and 
allocate caustic soda customers. Plaintiffs seek an unspecified amount of damages and injunctive relief. We believe we have 
meritorious legal positions and will continue to represent our interests vigorously in this matter. Any losses related to this 
matter are not currently estimable because of unresolved questions of fact and law, but, if resolved unfavorably to Olin, could 
have a material adverse effect on our financial position, cash flows or results of operations.

We, and our subsidiaries, are defendants in various other legal actions (including proceedings based on alleged 

exposures to asbestos) incidental to our past and current business activities.  We describe some of these matters in Item 3
—“Legal Proceedings.”  At December 31, 2019 and 2018, our consolidated balance sheets included liabilities for these other 
legal actions of $12.4 million and $15.6 million, respectively.  These liabilities do not include costs associated with legal 
representation.  Based on our analysis, and considering the inherent uncertainties associated with litigation, we do not believe 
that it is reasonably possible that these other legal actions will materially adversely affect our financial position, cash flows or 
results of operations. In connection with the October 5, 2015 acquisition of Dow’s U.S. Chlor Alkali and Vinyl, Global 
Chlorinated Organics and Global Epoxy businesses, the prior owner of the businesses retained liabilities related to litigation to 
the extent arising prior to October 5, 2015.  

During the ordinary course of our business, contingencies arise resulting from an existing condition, situation or set of 

circumstances involving an uncertainty as to the realization of a possible gain contingency.  In certain instances such as 
environmental projects, we are responsible for managing the clean-up and remediation of an environmental site.  There exists 
the possibility of recovering a portion of these costs from other parties.  We account for gain contingencies in accordance with 
the provisions of ASC 450 “Contingencies” and therefore do not record gain contingencies and recognize income until it is 
earned and realizable.

For the year ended December 31, 2018, we recognized an insurance recovery of $8.0 million in other operating income 

for a second quarter 2017 business interruption at our Freeport, TX vinyl chloride monomer facility.

Operating Activities

For 2019, cash provided by operating activities decreased by $290.5 million from 2018, primarily due to a decrease in 

operating results partially offset by a decrease in the investment in working capital from the prior year.  For 2019, working 
capital decreased $11.0 million compared to an increase of $71.6 million in 2018.  Receivables decreased from December 31, 
2018 by $12.3 million primarily as a result of lower sales in the fourth quarter of 2019 compared to the fourth quarter of 2018 
partially offset by a decrease in receivables sold under the accounts receivable factoring arrangement.  In 2019, inventories 
decreased by $13.0 million and accounts payable and accrued liabilities decreased by $11.0 million.  The decreases in 
inventories and accounts payable were primarily due to lower raw material costs. 

For 2018, cash provided by operating activities increased by $259.0 million from 2017, primarily due to an increase in 

operating results, partially offset by an increase in working capital.  For 2018, working capital increased $71.6 million 
compared to a decrease of $9.8 million in 2017.  Receivables increased from December 31, 2017 by $46.3 million primarily as 
a result of higher sales in the fourth quarter of 2018 compared to the fourth quarter of 2017 and a decrease in receivables sold 
under the accounts receivable factoring arrangement.  In 2018, inventories increased by $35.5 million and accounts payable and 
accrued liabilities increased by $14.5 million.  The increases in inventories and accounts payable were primarily due to higher 
raw material costs.  The increase in accrued liabilities was primarily related to the Information Technology Project.

Capital Expenditures

Capital spending was $385.6 million and $385.2 million in 2019 and 2018, respectively.  Capital spending was 78% and 

77% of depreciation in 2019 and 2018, respectively.

In 2017, we began a multi-year implementation of the Information Technology Project.  The project is planned to 
standardize business processes across the chemicals businesses with the objective of maximizing cost effectiveness, efficiency 
and control across our global operations.  At the end of 2019, Olin had successfully converted approximately 35% of our 
chemical business users to the new enterprise resource planning systems.  The project is anticipated to be substantially 
completed during 2020.  Total capital spending is forecast to be $220 million and associated expenses are forecast to be $190 
million, including duplicate information technology costs being incurred during the transition.  Our results for the years ended 
December 31, 2019, 2018 and 2017 include $56.0 million, $84.5 million and $35.8 million, respectively, of capital spending 
and $77.0 million, $36.5 million and $5.3 million, respectively, of expenses associated with this project.

In 2020, we expect our capital spending to be in the $250 million to $300 million range, which includes approximately 

$40 million of capital spending related to the Information Technology Project.

Investing Activities

On January 1, 2019, we sold our 9.1% limited partnership interest in Bay Gas for $20.0 million.  The sale closed on 

February 7, 2019 which resulted in a gain of $11.2 million.

Financing Activities

For the year ended December 31, 2019, our long-term debt borrowings, net of long-term repayments, were $80.8 
million, which included repayments of $543.0 million related to the $1,375.0 million Term Loan Facility and $150.0 million 
related to the Receivables Financing Agreement.

On July 16, 2019, Olin issued $750.0 million aggregate principal amount of 5.625% senior notes due August 1, 2029, 
which were registered under the Securities Act of 1933, as amended.  Proceeds from the 2029 Notes were used to redeem the 
remaining balance of the $1,375.0 million Term Loan Facility of $493.0 million and $150.0 million of the Receivables 
Financing Agreement.

On July 16, 2019, Olin entered into a new five-year, $2,000.0 million senior credit facility, which replaces the 
existing $1,975.0 million senior credit facility.  The 2019 Senior Credit Facility will mature in July 2024.  In December 2019, 
Olin amended the 2019 Senior Credit Facility which amended the restrictive covenants of the agreement, including expanding 
the coverage and leverage ratios to be less restrictive over the next two and a half years.  The 2019 Senior Credit Facility 
includes a senior unsecured delayed-draw term loan facility in an aggregate principal amount of up to $1,200.0 million and an 
$800.0 million senior unsecured revolving credit facility.  The Delayed Draw Term Loan Facility will be available on a delayed 
basis in up to three draws to be made on or prior to November 29, 2020. We expect the proceeds from the Delayed Draw Term 

41

Table of Contents

Loan Facility will be used to redeem the 9.75% senior notes due 2023 and the 10.00% senior notes due 2025 on or about 
October 15, 2020.  

For the year ended December 31, 2018, our long-term debt repayments, net of long-term debt borrowings, were $376.1 

million, which included $780.4 million related to the $1,375.0 million Term Loan Facility, $124.7 million related to the 
Receivables Financing Agreement and $20.0 million related to the 2017 Senior Revolving Credit Facility. 

On January 19, 2018, Olin issued $550.0 million aggregate principal amount of 5.00% senior notes due February 1, 2030 

(2030 Notes), which were registered under the Securities Act of 1933, as amended.  Interest on the 2030 Notes began accruing 
from January 19, 2018 and is paid semi-annually beginning on August 1, 2018.  Proceeds from the 2030 Notes were used to 
redeem $550.0 million of debt under the $1,375.0 million Term Loan Facility.

In 2019 and 2018, we repurchased and retired 8.0 million and 2.1 million shares, respectively, with a total value of 

$145.9 million and $50.0 million, respectively. 

In 2019 and 2018, we issued 0.1 million and 0.2 million shares, respectively, with a total value of $1.7 million and $3.4 

million, respectively, representing stock options exercised.  

In 2019, we paid debt issuance costs of $16.6 million, primarily for the issuance of the 2029 Notes and the 2019 Senior 

Credit Facility.  In 2018, we paid debt issuance costs of $8.5 million relating to the 2030 Notes. 

The percent of total debt to total capitalization increased to 58.0% at December 31, 2019 compared to 53.3% at 
December 31, 2018, primarily resulting from lower shareholders’ equity as a result of the payment of quarterly cash dividends 
and share repurchases. 

Dividends per common share were $0.80 in 2019 and 2018.  Total dividends paid on common stock amounted to $129.3 
million and $133.6 million in 2019 and 2018, respectively.  On January 24, 2020, our board of directors declared a dividend of 
$0.20 per share on our common stock, payable on March 10, 2020 to shareholders of record on February 10, 2020.

The payment of cash dividends is subject to the discretion of our board of directors and will be determined in light of 

then-current conditions, including our earnings, our operations, our financial condition, our capital requirements and other 
factors deemed relevant by our board of directors.  In the future, our board of directors may change our dividend policy, 
including the frequency or amount of any dividend, in light of then-existing conditions.

LIQUIDITY AND OTHER FINANCING ARRANGEMENTS

Our principal sources of liquidity are from cash and cash equivalents, cash flow from operations and borrowings under 

our Delayed Draw Term Loan Facility, 2019 Senior Revolving Credit Facility, Receivables Financing Agreement and AR 
Facilities.  Additionally, we believe that we have access to the debt and equity markets.

The overall cash increase of $42.1 million in 2019 primarily reflects our operating results and long-term debt 
borrowings, net of repayments, partially offset by dividend payments, capital spending and share repurchases.  We believe, 
based on current and projected levels of cash flow from our operations, together with our cash and cash equivalents on hand 
and the availability to borrow under our 2019 Senior Revolving Credit Facility, Delayed Draw Term Loan Facility, Receivables 
Financing Agreement and AR Facilities, we have sufficient liquidity to meet our short-term and long-term needs to make 
required payments of interest on our debt, fund our operating needs, working capital, the payment to Dow for our ethylene 
investment on or about the fourth quarter of 2020, and capital expenditure requirements and comply with the financial ratios in 
our debt agreements.

On April 26, 2018, our board of directors authorized a share repurchase program for the purchase of shares of common 

stock at an aggregate price of up to $500.0 million.  This program will terminate upon the purchase of $500.0 million of our 
common stock.  For the years ended December 31, 2019 and 2018, 8.0 million and 2.1 million shares, respectively, were 
repurchased and retired at a cost of $145.9 million and $50.0 million, respectively.  As of December 31, 2019, a total of 10.1 
million shares were repurchased and retired at a cost of $195.9 million and $304.1 million of common stock remained 
authorized to be repurchased.

For the year ended December 31, 2019, our long-term debt borrowings, net of long-term repayments, were $80.8 
million, which included repayments of $543.0 million related to the $1,375.0 million Term Loan Facility and $150.0 million 
related to the Receivables Financing Agreement.

On July 16, 2019, Olin issued $750.0 million aggregate principal amount of 5.625% senior notes due August 1, 2029, 
which were registered under the Securities Act of 1933, as amended.  Proceeds from the 2029 Notes were used to redeem the 
remaining balance of the $1,375.0 million Term Loan Facility of $493.0 million and $150.0 million of the Receivables 
Financing Agreement.

On July 16, 2019, Olin also entered into a new five-year, $2,000.0 million senior credit facility, which replaces the 
existing 2017 Senior Credit Facility.  The 2019 Senior Credit Facility will mature in July 2024.  In December 2019, Olin 
amended the 2019 Senior Credit Facility which amended the restrictive covenants of the agreement, including expanding the 
coverage and leverage ratios to be less restrictive over the next two and a half years.  The 2019 Senior Credit Facility includes a 
senior unsecured delayed-draw term loan facility in an aggregate principal amount of up to $1,200.0 million and an $800.0 
million senior unsecured revolving credit facility.  The 2019 Senior Revolving Credit Facility includes a $100.0 million letter of 
credit subfacility.  For the year ended December 31, 2019, we had $796.5 million available under our $800.0 million 2019 
Senior Revolving Credit Facility because we had issued $3.5 million of letters of credit.  The Delayed Draw Term Loan Facility 
will be available on a delayed basis in up to three draws to be made on or prior to November 29, 2020.  We expect the proceeds 
from the Delayed Draw Term Loan Facility will be used to redeem the 9.75% senior notes due 2023 and the 10.00% senior 
notes due 2025 on or about October 15, 2020.  If redeemed, Olin will be required to pay a call premium associated with the 
2023 and 2025 senior notes of approximately $42 million. 

Under the 2019 Senior Credit Facility, we may select various floating rate borrowing options.  The actual interest rate 

paid on borrowings under the 2019 Senior Credit Facility is based on a pricing grid which is dependent upon the leverage ratio 
as calculated under the terms of the applicable facility for the prior fiscal quarter.  The facility includes various customary 
restrictive covenants, including restrictions related to the ratio of debt to earnings before interest expense, taxes, depreciation 
and amortization (leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and amortization to 
interest expense (coverage ratio).  Compliance with these covenants is determined quarterly based on operating cash flows.  We 
were in compliance with all covenants and restrictions under all our outstanding credit agreements as of December 31, 2019, 
and no event of default had occurred that would permit the lenders under our outstanding credit agreements to accelerate the 
debt if not cured.  In the future, our ability to generate sufficient operating cash flows, among other factors, will determine the 
amounts available to be borrowed under these facilities.  As of December 31, 2019, there were no covenants or other 
restrictions that would have limited our ability to borrow under these facilities.

On January 19, 2018, Olin issued $550.0 million aggregate principal amount of 5.00% senior notes due February 1, 

2030, which were registered under the Securities Act of 1933, as amended.  Interest on the 2030 Notes began accruing from 
January 19, 2018 and is paid semi-annually beginning on August 1, 2018.  Proceeds from the 2030 Notes were used to redeem 
$550.0 million of debt under the $1,375.0 million Term Loan Facility. 

For the year ended December 31, 2018, long-term debt repayments included $780.4 million related to the $1,375.0 

million Term Loan Facility, $124.7 million related to the Receivables Financing Agreement and $20.0 million related to the 
2017 Senior Revolving Credit Facility.

In connection with the Acquisition, Olin and Dow entered into arrangements for the long-term supply of ethylene by 
Dow to Olin, pursuant to which, among other things, Olin made upfront payments in order to receive ethylene at producer 
economics and for certain reservation fees and for the option to obtain additional future ethylene supply at producer economics.  
On February 27, 2017, we exercised the remaining option to obtain additional ethylene at producer economics from Dow.  In 
connection with the exercise of this option, we also secured a long-term customer arrangement.  As a result, an additional 
payment will be made to Dow that is not to exceed $493 million on or about the fourth quarter of 2020. 

On July 16, 2019, our existing $250.0 million Receivables Financing Agreement was extended to July 15, 2022 and 

downsized to $10.0 million with the option to expand to $300.0 million.  The administrative agent for our Receivables 
Financing Agreement is PNC Bank, National Association.  Under the Receivables Financing Agreement, our eligible trade 
receivables are used for collateralized borrowings and continue to be serviced by us.  In addition, the Receivables Financing 
Agreement incorporates the leverage and coverage covenants that are contained in the $2,000.0 million senior credit facility.  
As of December 31, 2019 and 2018, we had zero and $125.0 million, respectively, drawn under the agreement.  As of 
December 31, 2019, we had $10.0 million of additional borrowing capacity under the Receivables Financing Agreement. 

Olin also has trade accounts receivable factoring arrangements (AR Facilities) and pursuant to the terms of the AR 
Facilities, certain of our subsidiaries may sell their accounts receivable up to a maximum of $315.0 million.  We will continue 
to service the outstanding accounts sold.  These receivables qualify for sales treatment under ASC 860 “Transfers and 
Servicing” and, accordingly, the proceeds are included in net cash provided by operating activities in the consolidated 

43

Table of Contents

statements of cash flows.  The gross amount of receivables sold for the years ended December 31, 2019 and 2018 totaled 
$984.8 million and $1,372.3 million, respectively.  The factoring discount paid under the AR Facilities is recorded as interest 
expense on the consolidated statements of operations.  The factoring discount for the years ended December 31, 2019 and 2018 
was $2.9 million and $4.3 million, respectively.  The agreements are without recourse and therefore no recourse liability has 
been recorded as of December 31, 2019.  As of December 31, 2019 and 2018, $63.1 million and $132.4 million, respectively, of 
receivables qualifying for sales treatment were outstanding and will continue to be serviced by us.

Cash flow from operations is variable as a result of both the seasonal and the cyclical nature of our operating results, 

which have been affected by seasonal and economic cycles in many of the industries we serve, such as vinyls, urethanes, 
bleach, ammunition and pulp and paper.  Cash flow from operations is affected by changes in chlorine, caustic soda and EDC 
selling prices caused by the changes in the supply/demand balance of these products, resulting in the Chlor Alkali Products and 
Vinyls segment having significant leverage on our earnings and cash flow.  For example, assuming all other costs remain 
constant, internal consumption remains approximately the same and we are operating at full capacity, a $10 selling price change 
per ton of chlorine equates to an approximate $10 million annual change in our revenues and pretax profit, a $10 selling price 
change per ton of caustic soda equates to an approximate $30 million annual change in our revenues and pretax profit, and a 
$0.01 selling price change per pound of EDC equates to an approximate $20 million annual change in our revenues and pretax 
profit.

For 2019, cash provided by operating activities decreased by $290.5 million from 2018, primarily due to a decrease in 

operating results partially offset by a decrease in the investment in working capital from the prior year.  For 2019, working 
capital decreased $11.0 million compared to an increase of $71.6 million in 2018.  Receivables decreased from December 31, 
2018 by $12.3 million primarily as a result of lower sales in the fourth quarter of 2019 compared to the fourth quarter of 2018 
partially offset by a decrease in receivables sold under the accounts receivable factoring arrangement.  In 2019, inventories 
decreased by $13.0 million and accounts payable and accrued liabilities decreased by $11.0 million.  The decreases in 
inventories and accounts payable were primarily due to lower raw material costs. 

Capital spending was $385.6 million and $385.2 million in 2019 and 2018, respectively.  Capital spending was 78% and 

77% of depreciation in 2019 and 2018, respectively.

In 2017, we began a multi-year implementation of the Information Technology Project.  The project is planned to 
standardize business processes across the chemicals businesses with the objective of maximizing cost effectiveness, efficiency 
and control across our global operations.  At the end of 2019, Olin had successfully converted approximately 35% of our 
chemical business users to the new enterprise resource planning systems.  The project is anticipated to be substantially 
completed during 2020.  Total capital spending is forecast to be $220 million and associated expenses are forecast to be $190 
million, including duplicate information technology costs being incurred during the transition.  Our results for the years ended 
December 31, 2019, 2018 and 2017 include $56.0 million, $84.5 million and $35.8 million, respectively, of capital spending 
and $77.0 million, $36.5 million and $5.3 million, respectively, of expenses associated with this project.

In 2020, we expect our capital spending to be in the $250 million to $300 million range, which includes approximately 

$40 million of capital spending related to the Information Technology Project.

At December 31, 2019, we had total letters of credit of $68.7 million outstanding, of which $3.5 million were issued 
under our 2019 Senior Revolving Credit Facility.  The letters of credit were used to support certain long-term debt, certain 
workers compensation insurance policies, certain plant closure and post-closure obligations and certain international pension 
funding requirements.

Our current debt structure is used to fund our business operations.  As of December 31, 2019, we had long-term 

borrowings, including the current installment and finance lease obligations, of $3,340.8 million, of which $155.9 million was at 
variable rates.  Annual maturities of long-term debt, including capital lease obligations, are $2.1 million in 2020, $1.0 million in 
2021, $200.7 million in 2022, $720.6 million in 2023, $70.7 million in 2024 and a total of $2,386.1 million thereafter.  
Commitments from banks under our Delayed Draw Term Loan Facility, 2019 Senior Revolving Credit Facility, Receivables 
Financing Agreement and AR Facilities are an additional source of liquidity.  Included within the $3,340.8 million of long-term 
borrowings on the consolidated balance sheet as of December 31, 2019 were unamortized deferred debt issuance costs and 
deferred losses on fair value interest rate swaps of $40.4 million.   

44

Table of Contents

We use interest rate swaps as a means of minimizing cash flow fluctuations that may arise from volatility in interest rates 

of our variable-rate borrowings.  In April 2016, we entered into three tranches of forward starting interest rate swaps whereby 
we agreed to pay fixed rates to the counterparties who, in turn, pay us floating rates on $1,100.0 million, $900.0 million and 
$400.0 million of our underlying floating-rate debt obligations.  Each tranche’s term length was for twelve months beginning 
on December 31, 2016, 2017 and 2018, respectively.  The swaps were designated as cash flow hedges of the risk of changes in 
interest payments associated with our variable-rate borrowings.  In July 2019, we terminated the remaining interest rate swap 
which resulted in a gain of $1.8 million that was recognized in interest expense. For the years ended December 31, 2019 and 
2018, $4.3 million and $8.9 million, respectively, of income was recorded to interest expense on the accompanying 
consolidated statements of operations related to these swap agreements. 

In April 2016, we entered into interest rate swaps on $250.0 million of our underlying fixed-rate debt obligations, 
whereby we agreed to pay variable rates to the counterparties who, in turn, pay us fixed rates.  In October 2016, we entered into 
interest rate swaps on an additional $250.0 million of our underlying fixed-rate debt obligations, whereby we agreed to pay 
variable rates to the counterparties who, in turn, pay us fixed rates.  We designated the April 2016 and October 2016 interest 
rate swap agreements as fair value hedges of the risk of changes in the value of fixed rate debt due to changes in interest rates 
for a portion of our fixed rate borrowings.  In August 2019, we terminated the April 2016 and October 2016 interest rate swaps 
which resulted in a loss of $2.3 million that will be deferred as an offset to the carrying value of the related debt and will be 
recognized to interest expense through October 2025.  As of December 31, 2019, $2.2 million of this loss was included in long-
term debt.  For the years ended December 31, 2019 and 2018, $2.6 million and $2.1 million, respectively, of expense was 
recorded to interest expense on the accompanying consolidated statements of operations related to these swap agreements.

We have registered an undetermined amount of securities with the SEC, so that, from time-to-time, we may issue debt 
securities, preferred stock and/or common stock and associated warrants in the public market under that registration statement.

Excludes unamortized debt issuance costs and deferred losses on fair value interest rate swaps of $40.4 million at 
December 31, 2019.  All debt obligations are assumed to be held until maturity.  

For the purposes of this table, we have assumed for all periods presented that there are no changes in the rates from those 
in effect at December 31, 2019 which ranged from 1.70% to 10.00% and excludes $15.7 million of remaining accretion 
expense related to the ethylene payment discount expected to be paid on or about the fourth quarter of 2020.  

(3)  Given the inherent uncertainty as to actual minimum funding requirements for qualified defined benefit pension plans, 
no amounts are included in this table for any period beyond one year.  Based on the current funding requirements, we 
will not be required to make any cash contributions to the domestic qualified defined benefit pension plan at least 
through 2020.  During 2019, we made a discretionary cash contribution to our domestic qualified defined benefit 
pension plan of $12.5 million. 

(4) 

These amounts are only estimated payments assuming for our foreign qualified pension plans a weighted average annual 
expected rate of return on pension plan assets of 5.2% and a discount rate on pension plan obligations of 1.4%.  These 
estimated payments are subject to significant variation and the actual payments may be more than the amounts 
estimated.  In connection with international qualified defined benefit pension plans we made cash contributions of $2.4 
million, $2.6 million and $1.7 million in 2019, 2018 and 2017, respectively, and we anticipate less than $5 million of 
cash contributions to international qualified defined benefit pension plans in 2020.

Table of Contents

Non-cancelable operating leases and purchasing commitments are utilized in our normal course of business for our 

projected needs.  Our operating lease commitments are primarily for railroad cars, but also include logistics, manufacturing, 
office and storage facilities and equipment, information technology equipment and land.  Virtually none of our lease 
agreements contain escalation clauses or step rent provisions.  We have supply contracts with various third parties for certain 
raw materials, including ethylene, electricity, propylene and benzene.  These contracts have initial terms ranging from several 
to 20 years.  For losses that we believe are probable and which are estimable, we have accrued for such amounts in our 
consolidated balance sheets.  In addition to the table above, we have various commitments and contingencies including: defined 
benefit and postretirement healthcare plans (as described below), environmental matters (see discussion above under 
“Environmental Matters”) and litigation claims (see Item 3—“Legal Proceedings”).

We have several defined benefit pension and defined contribution plans, as described in Note 14 “Pension Plans” and 
Note 18 “Contributing Employee Ownership Plan” in the notes to consolidated financial statements contained in Item 8.  We 
fund the defined benefit pension plans based on the minimum amounts required by law plus such amounts we deem 
appropriate.  We have postretirement healthcare plans that provide health and life insurance benefits to certain retired 
employees and their beneficiaries, as described in  Note 15 “Postretirement Benefits” in the notes to consolidated financial 
statements contained in Item 8.  The defined contribution and other postretirement plans are not pre-funded and expenses are 
paid by us as incurred.

We also have standby letters of credit of $68.7 million of which $3.5 million have been issued through our 2019 Senior 

Revolving Credit Facility.  At December 31, 2019, we had $796.5 million available under our 2019 Senior Revolving Credit 
Facility because we had issued $3.5 million of letters of credit.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our discussion and analysis of our financial condition and results of operations are based upon our consolidated 

financial statements, which have been prepared in accordance with accounting principles generally accepted in the United 
States.  The preparation of these financial statements requires us to make estimates and judgments that affect the reported 
amounts of assets, liabilities, sales and expenses, and related disclosure of contingent assets and liabilities.  Significant 
estimates in our consolidated financial statements include goodwill recoverability, environmental, restructuring and other 
unusual items, litigation, income tax reserves including deferred tax asset valuation allowances, pension, postretirement and 
other benefits and allowance for doubtful accounts.  We base our estimates on prior experience, current facts and circumstances 
and other assumptions.  Actual results may differ from these estimates.

We believe the following critical accounting policies affect the more significant judgments and estimates used in the 

preparation of the consolidated financial statements.

Goodwill

Goodwill is not amortized, but is reviewed for impairment annually in the fourth quarter and/or when circumstances or 

other events indicate that impairment may have occurred.  ASC 350 “Intangibles—Goodwill and Other” (ASC 350) permits 
entities to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its 
carrying amount before applying the two-step goodwill impairment test.  Circumstances that are considered as part of the 
qualitative assessment and could trigger the two-step impairment test include, but are not limited to:  a significant adverse 
change in the business climate; a significant adverse legal judgment; adverse cash flow trends; an adverse action or assessment 
by a government agency; unanticipated competition; sustained decline in our stock price; and a significant restructuring charge 
within a reporting unit.  We define reporting units at the business segment level or one level below the business segment 
level.  For purposes of testing goodwill for impairment, goodwill has been allocated to our reporting units to the extent it relates 
to each reporting unit.  

It is our practice, at a minimum, to perform a quantitative goodwill impairment test in the fourth quarter every three 

years.  In the fourth quarter of 2019, we performed our triennial quantitative goodwill impairment test for our reporting units.  
We use a discounted cash flow approach to develop the estimated fair value of a reporting unit when a quantitative review is 
performed.  Management judgment is required in developing the assumptions for the discounted cash flow model.  We also 
corroborate our discounted cash flow analysis by evaluating a market-based approach that considers earnings before interest, 
taxes, depreciation and amortization (EBITDA) multiples from a representative sample of comparable public companies.  As a 
further indicator that each reporting unit has been valued appropriately using a discounted cash flow model, the aggregate fair 
value of all reporting units is reconciled to the total market value of Olin.  An impairment would be recorded if the carrying 
amount of a reporting unit exceeded the estimated fair value.  Based on the aforementioned analysis, the estimated fair value of 

47

Table of Contents

our reporting units exceeded the carrying value of the reporting units.  No impairment charges were recorded for 2019, 2018 or 
2017.

The discount rate, profitability assumptions and terminal growth rate of our reporting units and the cyclical nature of the 
chlor alkali industry were the material assumptions utilized in the discounted cash flow model used to estimate the fair value of 
each reporting unit.  The discount rate reflects a weighted-average cost of capital, which is calculated based on observable 
market data.  Some of this data (such as the risk free or treasury rate and the pretax cost of debt) are based on the market data at 
a point in time.  Other data (such as the equity risk premium) are based upon market data over time for a peer group of 
companies in the chemical manufacturing or distribution industries with a market capitalization premium added, as applicable.

The discounted cash flow analysis requires estimates, assumptions and judgments about future events.  Our analysis uses 
our internally generated long-range plan.  Our discounted cash flow analysis uses the assumptions in our long-range plan about 
terminal growth rates, forecasted capital expenditures and changes in future working capital requirements to determine the 
implied fair value of each reporting unit.  The long-range plan reflects management judgment, supplemented by independent 
chemical industry analyses which provide multi-year chlor alkali industry operating and pricing forecasts.

We believe the assumptions used in our goodwill impairment analysis are appropriate and result in reasonable estimates 
of the implied fair value of each reporting unit.  However, given the economic environment and the uncertainties regarding the 
impact on our business, there can be no assurance that our estimates and assumptions, made for purposes of our goodwill 
impairment testing, will prove to be an accurate prediction of the future.  In order to evaluate the sensitivity of the fair value 
calculation on the goodwill impairment test, we applied a hypothetical 10% decrease to the fair value of each reporting unit.  
We also applied a hypothetical decrease of 100-basis points in our terminal growth rate or an increase of 100-basis points in our 
weighted-average cost of capital to test the fair value calculation.  In all cases, the estimated fair value of our reporting units 
derived in these sensitivity calculations exceeded the carrying value in excess of 10%.  If our assumptions regarding future 
performance are not achieved, we may be required to record goodwill impairment charges in future periods.  It is not possible 
at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be 
material.

Environmental

Accruals (charges to income) for environmental matters are recorded when it is probable that a liability has been 
incurred and the amount of the liability can be reasonably estimated, based upon current law and existing technologies.  These 
amounts, which are not discounted and are exclusive of claims against third parties, are adjusted periodically as assessments 
and remediation efforts progress or additional technical or legal information becomes available.  Environmental costs are 
capitalized if the costs increase the value of the property and/or mitigate or prevent contamination from future 
operations.  Environmental costs and recoveries are included in costs of goods sold.

Environmental exposures are difficult to assess for numerous reasons, including the identification of new sites, 
developments at sites resulting from investigatory studies, advances in technology, changes in environmental laws and 
regulations and their application, changes in regulatory authorities, the scarcity of reliable data pertaining to identified sites, the 
difficulty in assessing the involvement and financial capability of other PRPs and our ability to obtain contributions from other 
parties and the lengthy time periods over which site remediation occurs.  It is possible that some of these matters (the outcomes 
of which are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our 
financial position, cash flows or results of operations.

NEW ACCOUNTING PRONOUNCEMENTS

In December 2019, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 
2019-12, “Simplifying the Accounting for Income Taxes” which amends ASC 740 “Income Taxes” (ASC 740).  This update is 
intended to simplify accounting for income taxes by removing certain exceptions to the general principles in ASC 740 and 
amending existing guidance to improve consistent application of ASC 740.  This update is effective for fiscal years beginning 
after December 15, 2020 and interim periods within those fiscal years.  The guidance in this update has various elements, some 
of which are applied on a prospective basis and others on a retrospective basis with earlier application permitted.  We adopted 
this update on January 1, 2020 which did not have a material impact on our consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” which amends ASC 
350.  This update will simplify the measurement of goodwill impairment by eliminating Step 2 from the goodwill impairment 
test.  This update will require an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value 
of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount 
48

Table of Contents

exceeds the reporting unit’s fair value.  The update does not modify the option to perform the qualitative assessment for a 
reporting unit to determine if the quantitative impairment test is necessary.  This update is effective for fiscal years beginning 
after December 15, 2019, and interim periods within those fiscal years.  The guidance in this update is applied on a prospective 
basis, with earlier application permitted.  We adopted this update on January 1, 2020 which did not have a material impact on 
our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” (ASU 
2016-13) which amends ASC 326 “Financial Instruments—Credit Losses” (ASC 326).  Subsequent to the issuance of ASU 
2016-13, ASC 326 was amended by various updates that amend and clarify the impact and implementation of the 
aforementioned update.  The new guidance introduces the current expected credit loss (CECL) model, which will require an 
entity to record an allowance for credit losses for certain financial instruments and financial assets, including trade receivables, 
based on expected losses rather than incurred losses.  Under this update, on initial recognition and at each reporting period, an 
entity will be required to recognize an allowance that reflects the entity’s current estimate of credit losses expected to be 
incurred over the life of the financial instrument.  This update is effective for fiscal years beginning after December 15, 2019, 
and interim periods within those fiscal years.  The guidance in this update has various elements, some of which are applied on a 
prospective basis and others on a retrospective basis, with earlier application permitted.  We adopted this update on January 1, 
2020 which did not have a material impact on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02 “Leases,” (ASU 2016-02) which supersedes ASC 840 “Leases” and 
creates a new topic, ASC 842 “Leases” (ASC 842).  Subsequent to the issuance of ASU 2016-02, ASC 842 was amended by 
various updates that amend and clarify the impact and implementation of the aforementioned update.  These updates require 
lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 
months on its balance sheet.  Upon initial application, the provisions of these updates are required to be applied using the 
modified retrospective method which requires retrospective adoption to each prior reporting period presented with the 
cumulative effect of adoption recorded to the earliest reporting period presented.  An optional transition method can be utilized 
which requires application of these updates beginning on the date of adoption with the cumulative effect of initially applying 
these updates recognized at the date of initial adoption.  These updates also expand the required quantitative and qualitative 
disclosures surrounding leases.  These updates are effective for fiscal years beginning after December 15, 2018 and interim 
periods within those fiscal years, with earlier application permitted.  We adopted these updates on January 1, 2019 using the 
optional transition method.  Accordingly, prior periods were not retrospectively adjusted.  Adoption of these updates resulted in 
the recording of operating lease assets and lease liabilities on our consolidated balance sheet of $291.9 million as of January 1, 
2019. Our assets and liabilities for finance leases remained unchanged.  We also recognized the cumulative effect of applying 
these updates as an adjustment to retained earnings of $11.2 million, net of tax, which was primarily related to the recognition 
of previously deferred sale/leaseback gains.  Our consolidated statements of operations and cash flows, along with our 
compliance with all covenants and restrictions under all our outstanding credit agreements, were not impacted by this adoption.  
These updates also impacted our accounting policies, internal controls and disclosures related to leases.  Expanded disclosures 
regarding leases are included in Note 23 “Leases” in the notes to the consolidated financial statements contained in Item 8.

DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risk in the normal course of our business operations due to our purchases of certain 

commodities, our ongoing investing and financing activities and our operations that use foreign currencies.  The risk of loss can 
be assessed from the perspective of adverse changes in fair values, cash flows and future earnings.  We have established 
policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to 
such risks.  ASC 815 requires an entity to recognize all derivatives as either assets or liabilities in the consolidated balance 
sheets and measure those instruments at fair value.  In accordance with ASC 815, we designate derivative contracts as cash 
flow hedges of forecasted purchases of commodities and forecasted interest payments related to variable-rate borrowings and 
designate certain interest rate swaps as fair value hedges of fixed-rate borrowings.  We do not enter into any derivative 
instruments for trading or speculative purposes.

Energy costs, including electricity and natural gas, and certain raw materials used in our production processes are subject 

to price volatility.  Depending on market conditions, we may enter into futures contracts, forward contracts, commodity swaps 
and put and call option contracts in order to reduce the impact of commodity price fluctuations.  The majority of our 
commodity derivatives expire within one year.  

For derivative instruments that are designated and qualify as a cash flow hedge, the change in fair value of the derivative 

is recognized as a component of other comprehensive income (loss) until the hedged item is recognized in earnings.

49

Table of Contents

We use cash flow hedges for certain raw material and energy costs such as copper, zinc, lead, ethane, electricity and 

natural gas to provide a measure of stability in managing our exposure to price fluctuations associated with forecasted 
purchases of raw materials and energy used in our manufacturing process.  Settlements on commodity derivative contracts 
resulted in (losses) gains of $(31.1) million, $5.4 million, and $1.5 million in 2019, 2018, and 2017, respectively which were 
included in cost of goods sold.  At December 31, 2019, we had open derivative notional contract positions through 2027 
totaling $174.6 million (2018—$116.5 million).  If all open futures contracts had been settled on December 31, 2019, we would 
have recognized a pretax loss of $17.6 million.

If commodity prices were to remain at December 31, 2019 levels, approximately $12.7 million of deferred losses, net of 

tax, would be reclassified into earnings during the next twelve months.  The actual effect on earnings will be dependent on 
actual commodity prices when the forecasted transactions occur.

We use interest rate swaps as a means of minimizing cash flow fluctuations that may arise from volatility in interest rates 

of our variable-rate borrowings.  In April 2016, we entered into three tranches of forward starting interest rate swaps whereby 
we agreed to pay fixed rates to the counterparties who, in turn, pay us floating rates on $1,100.0 million, $900.0 million and 
$400.0 million of our underlying floating-rate debt obligations.  Each tranche’s term length was for twelve months beginning 
on December 31, 2016, 2017 and 2018, respectively.  We have designated the swaps as cash flow hedges of the risk of changes 
in interest payments associated with our variable-rate borrowings.  In July 2019, we terminated the remaining interest rate swap 
agreement which resulted in a gain of $1.8 million that was recognized in interest expense for the year ended December 31, 
2019.  For the years ended December 31, 2019, 2018 and 2017, $4.3 million, $8.9 million and $3.1 million, respectively, of 
income was recorded to interest expense on the accompanying consolidated statements of operations related to these swap 
agreements.

We also use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal 

levels.  For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as 
well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings.  We 
include the gain or loss on the hedged items (fixed-rate borrowings) in the same line item, interest expense, as the offsetting 
loss or gain on the related interest rate swaps.  

In April 2016, we entered into interest rate swaps on $250.0 million of our underlying fixed-rate debt obligations, 
whereby we agreed to pay variable rates to the counterparties who, in turn, pay us fixed rates.  In October 2016, we entered into 
interest rate swaps on an additional $250.0 million of our underlying fixed-rate debt obligations, whereby we agreed to pay 
variable rates to the counterparties who, in turn, pay us fixed rates.  We designated the April 2016 and October 2016 interest 
rate swap agreements as fair value hedges of the risk of changes in the value of fixed-rate debt due to changes in interest rates 
for a portion of our fixed-rate borrowings.  In August 2019, we terminated the April 2016 and October 2016 interest rate swaps 
which resulted in a loss of $2.3 million that will be deferred as an offset to the carrying value of the related debt and will be 
recognized to interest expense through October 2025.  As of December 31, 2019, $2.2 million of this loss was included in long-
term debt in the consolidated balance sheet.  For the years ended December 31, 2019 and 2018, $2.6 million and $2.1 million, 
respectively, of expense and for the year ended December 31, 2017, $2.9 million of income was recorded to interest expense on 
the accompanying consolidated statements of operations related to these swap agreements. 

We actively manage currency exposures that are associated with net monetary asset positions, currency purchases and 
sales commitments denominated in foreign currencies and foreign currency denominated assets and liabilities created in the 
normal course of business.  We enter into forward sales and purchase contracts to manage currency risk to offset our net 
exposures, by currency, related to the foreign currency denominated monetary assets and liabilities of our operations.  At 
December 31, 2019, we had outstanding forward contracts to buy foreign currency with a notional value of $140.6 million and 
to sell foreign currency with a notional value of $99.2 million.  All of the currency derivatives expire within one year and are 
for U.S. dollar (USD) equivalents.  The counterparties to the forward contracts are large financial institutions; however, the risk 
of loss to us in the event of nonperformance by a counterparty could be significant to our financial position or results of 
operations.  At December 31, 2018, we had outstanding forward contracts to buy foreign currency with a notional value of 
$123.7 million and to sell foreign currency with a notional value of $82.6 million.

Our foreign currency forward contracts and certain commodity derivatives did not meet the criteria to qualify for hedge 

accounting.  The effect on operating results of items not qualifying for hedge accounting was a (loss) gain of $(4.0) million, 
$(5.4) million and $1.8 million in 2019, 2018 and 2017, respectively.

Item 7A.  QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We are exposed to market risk in the normal course of our business operations due to our purchases of certain 

commodities, our ongoing investing and financing activities and our operations that use foreign currencies.  The risk of loss can 
be assessed from the perspective of adverse changes in fair values, cash flows and future earnings.  We have established 
policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to 
such risks.

Energy costs, including electricity and natural gas, and certain raw materials used in our production processes are subject 

to price volatility.  Depending on market conditions, we may enter into futures contracts, forward contracts, commodity swaps 
and put and call option contracts in order to reduce the impact of commodity price fluctuations.  As of December 31, 2019, we 
maintained open positions on commodity contracts with a notional value totaling $174.6 million ($116.5 million at December 
31, 2018).  Assuming a hypothetical 10% increase in commodity prices, which are currently hedged, as of December 31, 2019, 
we would experience an $17.5 million ($11.7 million at December 31, 2018) increase in our cost of inventory purchased, which 
would be substantially offset by a corresponding increase in the value of related hedging instruments.

We transact business in various foreign currencies other than the USD which exposes us to movements in exchange rates 

which may impact revenue and expenses, assets and liabilities and cash flows. Our significant foreign currency exposure is 
denominated with European currencies, primarily the Euro, although exposures also exist in other currencies of Asia Pacific, 
Latin America, Middle East and Africa.  For all derivative positions, we evaluated the effects of a 10% shift in exchange rates 
between those currencies and the USD, holding all other assumptions constant. Unfavorable currency movements of 10% 
would negatively affect the fair values of the derivatives held to hedge currency exposures by $21.3 million. These unfavorable 
changes would generally have been offset by favorable changes in the values of the underlying exposures.

We are exposed to changes in interest rates primarily as a result of our investing and financing activities.  Our current 

debt structure is used to fund business operations, and commitments from banks under our Delayed Draw Term Loan Facility, 
2019 Senior Revolving Credit Facility, Receivables Financing Agreement and AR Facilities are sources of liquidity.  As of 
December 31, 2019, we had long-term borrowings, including current installments of long-term debt and finance lease 
obligations, of $3,340.8 million ($3,230.3 million at December 31, 2018) of which $155.9 million ($823.9 million at December 
31, 2018) was issued at variable rates.  Included within long-term borrowings on the consolidated balance sheets were deferred 
debt issuance costs and deferred losses on fair value interest rate swaps.

Assuming no changes in the $155.9 million of variable-rate debt levels from December 31, 2019, we estimate that a 

hypothetical change of 100-basis points in the LIBOR interest rates from 2019 would impact annual interest expense by $1.6 
million. 

Our interest rate swaps reduced interest expense by $1.7 million, $6.8 million and $6.1 million in 2019, 2018 and 2017, 

respectively.

If the actual changes in commodities, foreign currency or interest pricing is substantially different than expected, the net 

impact of commodity risk, foreign currency risk or interest rate risk on our cash flow may be materially different than that 
disclosed above.

We do not enter into any derivative financial instruments for speculative purposes.

Item 8.  CONSOLIDATED FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

MANAGEMENT REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING

The management of Olin Corporation is responsible for establishing and maintaining adequate internal control over 
financial reporting.  Olin’s internal control system was designed to provide reasonable assurance to the company’s management 
and board of directors regarding the preparation and fair presentation of published financial statements.

All internal control systems, no matter how well designed, have inherent limitations.  Therefore, even those systems 

determined to be effective can provide only reasonable assurance with respect to financial statement preparation and 
presentation, and may not prevent or detect all misstatements.

The management of Olin Corporation has assessed the effectiveness of the company’s internal control over financial 

reporting as of December 31, 2019.  In making this assessment, we used the criteria set forth by the Committee of Sponsoring 
Organizations of the Treadway Commission (COSO) in Internal Control - Integrated Framework (2013) to guide our analysis 
and assessment.  Based on our assessment as of December 31, 2019, the company’s internal control over financial reporting 
was effective based on those criteria.

Our independent registered public accountants, KPMG LLP, have audited and issued a report on our internal control 

over financial reporting, which appears in this Form 10-K.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors 
Olin Corporation:

Opinions on the Consolidated Financial Statements and Internal Control Over Financial Reporting

We have audited the accompanying consolidated balance sheets of Olin Corporation and subsidiaries (the Company) as of 
December 31, 2019 and 2018, the related consolidated statements of operations, comprehensive income (loss), shareholders’ 
equity, and cash flows for each of the years in the three-year period ended December 31, 2019, and the related notes 
(collectively, the consolidated financial statements).  We also have audited the Company’s internal control over financial 
reporting as of December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by 
the Committee of Sponsoring Organizations of the Treadway Commission.  

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial 
position of the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the 
years in the three-year period ended December 31, 2019, in conformity with U.S. generally accepted accounting principles.  
Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of 
December 31, 2019, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee 
of Sponsoring Organizations of the Treadway Commission.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company has changed its method of accounting for leases 
as of January 1, 2019 due to the adoption of Accounting Standards Update 2016-02 - Leases and amendments thereto.

Basis for Opinions

The Company’s management is responsible for these consolidated 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 the accompanying Management Report on Internal Control Over Financial Reporting.  Our responsibility is to express an 
opinion on the Company’s consolidated financial statements and an opinion on the Company’s internal control over financial 
reporting based on our audits.  We are a public accounting firm registered with the Public Company Accounting Oversight 
Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. 
federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB.  Those standards require that we plan and perform 
the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, 
whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material 
respects.  

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement 
of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks.  
Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated 
financial statements.  Our audits also included evaluating the accounting principles used and significant estimates made by 
management, as well as evaluating the overall presentation of the consolidated financial statements.  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.

Definition and Limitations of Internal Control Over Financial Reporting

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 (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and 
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit 
preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and 

54

Table of Contents

expenditures of the company are being made only in accordance with authorizations of management and directors of the 
company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or 
disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements.  Also, 
projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate 
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial 
statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or 
disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or 
complex judgments.  The communication of critical audit matters does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate 
opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Evaluation of the recoverability of the carrying value of goodwill

As discussed in Notes 2 and 12 to the consolidated financial statements, the carrying amount of goodwill as of December 
31, 2019 was $2,119.7 million.  Of this amount, the goodwill balances of the Chlor Alkali Products and Vinyls and 
Epoxy reporting units were $1,832.7 million and $287.0 million, respectively.  The Company performs a goodwill 
impairment assessment on an annual basis during the fourth quarter of each fiscal year or whenever events and changes 
in circumstances indicate that the carrying value of a reporting unit might exceed the fair value of each reporting unit.

We identified the evaluation of the recoverability of the carrying value of goodwill for each reporting unit as a critical 
audit matter. Subjective and challenging auditor judgment was required to evaluate certain assumptions used in the 
Company’s estimate of the fair value of the reporting units.  Specifically, the cash flow projections and the discount rate 
assumptions underlying the Company’s determination of the fair value of the reporting units were challenging to audit as 
changes to those assumptions had a significant effect on the assessment of the fair value for the reporting units.

The primary procedures that we performed to address this critical audit matter included the following. We tested certain 
internal controls over the Company’s goodwill impairment assessment process, including controls related to the 
development of the cash flow and discount rate assumptions.  We evaluated the Company’s cash flow projection 
assumptions for each reporting unit, including revenue growth rates and forecasted margins, by comparing them to the 
Company’s past history, industry reports, and peer companies’ analyst reports and historical growth rates.  We performed 
sensitivity analyses over the cash flow projections and discount rate assumptions to assess their impact on the 
Company’s determination that the fair value of each reporting unit exceeded its carrying value. In addition, we involved 
a valuation professional with specialized skills and knowledge who assisted in:

–  Evaluating the Company’s selection of discount rates, by comparing them against a discount rate range that was 

independently developed using publicly available market data for comparable entities, and

–  Developing an estimate of each reporting unit’s fair value using the reporting unit’s cash flow forecast and 

independently developed discount rates, and comparing the results of our estimate of fair value to the Company’s 
fair value estimate.

Determination of environmental obligations

As discussed in Notes 2 and 22 to the consolidated financial statements, the Company has recorded liabilities for future 
environmental expenditures of $139.0 million as of December 31, 2019.  The Company accrues a liability for 
environmental matters when it is probable that a liability has been incurred and the amount of the liability can be 
reasonably estimated based upon current law and existing technologies.

We identified the determination of the environmental liabilities as a critical audit matter.  This required challenging 
auditor judgment due to the nature of the estimate and assumptions, including judgments about future events and 
uncertainties and the time period over which remediation will occur.

The primary procedures that we performed to address this critical audit matter included the following.  We tested certain 
internal controls over the Company’s process to estimate environmental obligations, including controls related to the

monitoring of the liability as compared to remedial activities required by regulatory authority.  We involved an 
environmental professional with specialized skills and knowledge who assisted in assessing the Company’s 
environmental specialist’s qualifications and in evaluating the Company’s planned remediation activities for certain sites.  
We compared the Company’s planned remediation activities to those communicated to regulatory authorities, those 
commonly observed in conducting remediation, and to the liability recorded.  We also considered the Company’s 
changes in the liability and assumptions from those used in the prior year.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1.  DESCRIPTION OF BUSINESS

Olin Corporation (Olin) is a Virginia corporation, incorporated in 1892, having its principal executive offices in Clayton, 

MO.  We are a manufacturer concentrated in three business segments:  Chlor Alkali Products and Vinyls, Epoxy and 
Winchester.  The Chlor Alkali Products and Vinyls segment manufactures and sells chlorine and caustic soda, ethylene 
dichloride and vinyl chloride monomer, methyl chloride, methylene chloride, chloroform, carbon tetrachloride, 
perchloroethylene, trichloroethylene and vinylidene chloride, hydrochloric acid, hydrogen, bleach products and potassium 
hydroxide.  The Epoxy segment produces and sells a full range of epoxy materials, including allyl chloride, epichlorohydrin, 
liquid epoxy resins, solid epoxy resins and downstream products such as differentiated epoxy resins and additives.  The 
Winchester segment produces and sells sporting ammunition, reloading components, small caliber military ammunition and 
components, and industrial cartridges.  

NOTE 2.  ACCOUNTING POLICIES

The preparation of the consolidated financial statements requires estimates and assumptions that affect amounts reported 

and disclosed in the financial statements and related notes.  Actual results could differ from those estimates.

Basis of Presentation

The consolidated financial statements include the accounts of Olin and all majority-owned subsidiaries.  Investment in 

our affiliates are accounted for on the equity method.  Accordingly, we include only our share of earnings or losses of these 
affiliates in consolidated net income (loss).  Certain reclassifications were made to prior year amounts to conform to the 2019 
presentation.

Revenue Recognition

In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-09, 

“Revenue from Contracts with Customers” (ASU 2014-09), which amends Accounting Standards Codification (ASC) 605 
“Revenue Recognition” and creates a new topic, ASC 606 “Revenue from Contracts with Customers” (ASC 606).  Subsequent 
to the issuance of ASU 2014-09, ASC 606 was amended by various updates that amend and clarify the impact and 
implementation of the aforementioned update.  We adopted these updates on January 1, 2018 using the modified retrospective 
transition method.  The cumulative effect of applying the updates did not have a material impact on our consolidated financial 
statements.  The most significant impact the updates had was on our accounting policies and disclosures on revenue 
recognition. 

We derive our revenues primarily from the manufacturing and delivery of goods to customers.  Revenues are recognized 

on sales of goods at the time when control of those goods is transferred to our customers at an amount that reflects the 
consideration to which we expect to be entitled in exchange for those goods.  We primarily sell our goods directly to customers, 
and to a lesser extent, through distributors.  Payment terms are typically 30 to 90 days from date of invoice.  Our contracts do 
not typically have a significant financing component.  Right to payment is determined at the point in time in which control has 
transferred to the customer.

A performance obligation is a promise in a contract to transfer a distinct good to the customer.  At contract inception, we 
assess the goods promised in our contracts with customers and identify a performance obligation for each promise to transfer to 
the customer a good (or bundle of goods) that is distinct.  A contract’s transaction price is based on the price stated in the 
contract and allocated to each distinct performance obligation and revenue is recognized when the performance obligation is 
satisfied.  Substantially all of our contracts have a single distinct performance obligation or multiple performance obligations 
which are distinct and represent individual promises within the contract.  Substantially all of our performance obligations are 
satisfied at a single point in time, when control is transferred, which is generally upon shipment or delivery as stated in the 
contract terms.

62

Table of Contents

All taxes assessed by governmental authorities that are both imposed on and concurrent with our revenue-producing 

transactions and collected from our customers are excluded from the measurement of the transaction price.  Shipping and 
handling fees billed to customers are included in revenue and are considered activities to fulfill the promise to transfer the 
good.  Allowances for estimated returns, discounts and rebates are considered variable consideration, which may be 
constrained, and are estimated and recognized when sales are recorded.  The estimates are based on various market data, 
historical trends and information from customers.  Actual returns, discounts and rebates have not been materially different from 
estimates.  For all contracts that have a duration of one year or less at contract inception, we do not adjust the promised amount 
of consideration for the effects of a significant financing component.

Substantially all of our revenue is derived from contracts with an original expected length of time of one year or less and  

for which we recognize revenue for the amount in which we have the right to invoice at the point in time in which control has 
transferred to the customer.  However, a portion of our revenue is derived from long-term contracts which have contract periods 
that vary between one to multi-year.  Certain of these contracts represent contracts with minimum purchase obligations, which 
can be substantially different than the actual revenue recognized.  Such contracts consist of varying types of products across our 
chemical businesses.  Certain contracts include variable volumes and/or variable pricing with pricing provisions tied to 
commodity, consumer price or other indices.  The transaction price allocated to the remaining performance obligations related 
to our contracts was excluded from the disclosure of our remaining performance obligations based on the following practical 
expedients that we elected to apply: (i) contracts with index-based pricing or variable volume attributes in which such variable 
consideration is allocated entirely to a wholly unsatisfied performance obligation; and (ii) contracts with an original expected 
duration of one year or less.

Refer to Note 21 “Segment Information” for information regarding the disaggregation of revenue by primary 

geographical markets and major product lines.

Cost of Goods Sold and Selling and Administration Expenses

Cost of goods sold includes the costs of inventory sold, related purchasing, distribution and warehousing costs, costs 

incurred for shipping and handling, depreciation and amortization expense related to these activities and environmental 
remediation costs and recoveries.  Selling and administration expenses include personnel costs associated with sales, marketing 
and administration, research and development, legal and legal-related costs, consulting and professional services fees, 
advertising expenses, depreciation expense related to these activities, foreign currency translation and other similar costs.

Acquisition-related Costs

Acquisition-related costs include advisory, legal, accounting and other professional fees incurred in connection with the 

purchase and integration of our acquisitions.  Acquisition-related costs also may include costs which arise as a result of 
acquisitions, including contractual change in control provisions, contract termination costs, compensation payments related to 
the acquisition or pension and other postretirement benefit plan settlements. 

Other Operating Income (Expense)

Other operating income (expense) consists of miscellaneous operating income items, which are related to our business 

activities, and gains (losses) on disposition of property, plant and equipment.

Included in other operating income were the following:

Gains (losses) on disposition of property, plant and equipment, net

63

Table of Contents

Other Income (Expense)

Other income (expense) consists of non-operating income and expense items which are not related to our primary 

business activities.  

Foreign Currency Translation

Our worldwide operations utilize the U.S. dollar (USD) or local currency as the functional currency, where applicable.  For 

foreign entities where the USD is the functional currency, gains and losses resulting from balance sheet translations are 
included in selling and administration.  For foreign entities where the local currency is the functional currency, assets and 
liabilities denominated in local currencies are translated into USD at end-of-period exchange rates and the resultant translation 
adjustments are included in accumulated other comprehensive loss.  Assets and liabilities denominated in other than the local 
currency are remeasured into the local currency prior to translation into USD and the resultant exchange gains or losses are 
included in income in the period in which they occur.  Income and expenses are translated into USD using an approximation of 
the average rate prevailing during the period.  We change the functional currency of our separate and distinct foreign entities 
only when significant changes in economic facts and circumstances indicate clearly that the functional currency has changed.

Cash and Cash Equivalents

All highly liquid investments, with a maturity of three months or less at the date of purchase, are considered to be cash 

equivalents.

Short-Term Investments

We classify our marketable securities as available-for-sale, which are reported at fair market value with unrealized gains 
and losses included in accumulated other comprehensive loss, net of applicable taxes.  The fair value of marketable securities is 
determined by quoted market prices.  Realized gains and losses on sales of investments, as determined on the specific 
identification method, and declines in value of securities judged to be other-than-temporary are included in other income 
(expense) in the consolidated statements of operations.  Interest and dividends on all securities are included in interest income 
and other income (expense), respectively.  As of December 31, 2019 and 2018, we had no short-term investments recorded on 
our consolidated balance sheets.  

Allowance for Doubtful Accounts Receivable

We evaluate the collectibility of accounts receivable based on a combination of factors.  We estimate an allowance for 
doubtful accounts as a percentage of net sales based on historical bad debt experience.  This estimate is periodically adjusted 
when we become aware of a specific customer’s inability to meet its financial obligations (e.g., bankruptcy filing) or as a result 
of changes in the overall aging of accounts receivable.  While we have a large number of customers that operate in diverse 
businesses and are geographically dispersed, a general economic downturn in any of the industry segments in which we operate 
could result in higher than expected defaults, and, therefore, the need to revise estimates for the provision for doubtful accounts 
could occur.

Inventories

Inventories are valued at the lower of cost and net realizable value.  For U.S. inventories, inventory costs are determined 

principally by the last-in, first-out (LIFO) method of inventory accounting while for international inventories, inventory costs 
are determined principally by the first-in, first-out (FIFO) method of inventory accounting.  Costs for other inventories have 
been determined principally by the average-cost method (primarily operating supplies, spare parts and maintenance 
parts).  Elements of costs in inventories include raw materials, direct labor and manufacturing overhead.

64

Table of Contents

Property, Plant and Equipment

Property, plant and equipment are recorded at cost.  Depreciation is computed on a straight-line basis over the estimated 

useful lives of the related assets.  Interest costs incurred to finance expenditures for major long-term construction projects are 
capitalized as part of the historical cost and included in property, plant and equipment and are depreciated over the useful lives 
of the related assets.  Leasehold improvements are amortized over the term of the lease or the estimated useful life of the 
improvement, whichever is shorter.  Start-up costs are expensed as incurred.  Expenditures for maintenance and repairs are 
charged to expense when incurred while the costs of significant improvements, which extend the useful life of the underlying 
asset, are capitalized.

Property, plant and equipment are reviewed for impairment when conditions indicate that the carrying values of the 

assets may not be recoverable.  Such impairment conditions include an extended period of idleness or a plan of disposal.  If 
such impairment indicators are present or other factors exist that indicate that the carrying amount of an asset may not be 
recoverable, we determine whether impairment has occurred through the use of an undiscounted cash flow analysis at the 
lowest level for which identifiable cash flows exist.  For our Chlor Alkali Products and Vinyls, Epoxy and Winchester 
segments, the lowest level for which identifiable cash flows exist is the operating facility level or an appropriate grouping of 
operating facilities level.  The amount of impairment loss, if any, is measured by the difference between the net book value of 
the assets and the estimated fair value of the related assets.

Leases

In February 2016, the FASB issued ASU 2016-02 “Leases,” (ASU 2016-02) which supersedes ASC 840 “Leases” and 
creates a new topic, ASC 842 “Leases” (ASC 842).  Subsequent to the issuance of ASU 2016-02, ASC 842 was amended by 
various updates that amend and clarify the impact and implementation of the aforementioned update.  Upon initial application, 
the provisions of these updates are required to be applied using the modified retrospective method which requires retrospective 
adoption to each prior reporting period presented with the cumulative effect of adoption recorded to the earliest reporting 
period presented.  An optional transition method can be utilized which requires application of these updates beginning on the 
date of adoption with the cumulative effect of initially applying these updates recognized at the date of initial adoption.  We 
adopted these updates on January 1, 2019 using the optional transition method.  Consequently, our comparative periods have 
not been retrospectively adjusted for the new lease requirements.  In addition, we elected the following practical expedients: 

–  We elected the package of practical expedients permitted under the transition guidance within the new standard, 

which among other things, allowed us to carry forward the historical lease classification. 

–  We elected the practical expedient related to land easements, allowing us to carry forward our accounting treatment 

for land easements on existing agreements.

–  We elected the short-term practical expedient for all classes of lease assets, which allows us to not record leases with 
an initial term of 12 months or less on the balance sheet, and instead recognize the expense straight-line over the 
lease term.

–  We elected the practical expedient to not separate lease components from non-lease components for all asset classes. 

Adoption of these updates resulted in the recording of operating lease assets and lease liabilities on our consolidated 

balance sheet of $291.9 million as of January 1, 2019.  Our assets and liabilities for finance leases remained unchanged.  We 
also recognized the cumulative effect of applying these updates as an adjustment to retained earnings of $11.2 million, net of 
tax, which was primarily related to the recognition of previously deferred sale/leaseback gains.  Our consolidated statements of 
operations and cash flows, along with our compliance with all covenants and restrictions under all our outstanding credit 
agreements, were not impacted by this adoption.

We determine if an arrangement is a lease at inception of the contract.  Operating lease assets represent our right to use 

an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the 
lease.  Operating lease assets and liabilities are recognized at commencement date based on the present value of fixed lease 
payments over the lease term.  Our lease commitments are primarily for railcars, but also include logistics, manufacturing, 
storage, real estate and information technology assets.  Leases with an initial term of 12 months or less are not recorded on the 
balance sheet; instead, we recognize lease expense for these leases on a straight-line basis over the lease term.  We do not 
account for lease components (e.g., fixed payments to use the underlying lease asset) separately from the non-lease components 
(e.g., fixed payments for common-area maintenance costs and other items that transfer a good or service).  Some of our leases 
include variable lease payments, which primarily result from changes in consumer price and other market-based indices, which 
are generally updated annually, and maintenance and usage charges.  These variable payments are excluded from the 
calculation of our lease assets and liabilities.

Table of Contents

Most leases include one or more options to renew, with renewal terms that can extend the lease term from one to many 
years.  The exercise of lease renewal options is typically at our sole discretion.  Certain leases also include options to purchase 
the leased asset.  We do not include options to renew or purchase leased assets in the measurement of lease liabilities unless 
those options are highly certain of exercise.  The depreciable life of assets and leasehold improvements are limited by the 
expected lease term, unless there is a transfer of title or purchase option reasonably certain of exercise.  We have operating 
leases with terms that require us to guarantee a portion of the residual value of the leased assets upon termination of the lease as 
well as other guarantees.  These residual value guarantees consist primarily of leases for railcars.  Residual value guarantee 
payments that become probable and estimable are accrued as part of the lease liability and recognized over the remaining life of 
the applicable lease.  Our current expectation is that the likelihood of material residual guarantee payments is remote.  We 
utilize the interest rate implicit in the lease to determine the lease liability when the interest rate can be determined.  As most of 
our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at the lease 
commencement date in determining the present value of lease payments.  We estimate the incremental borrowing rate based on 
the geographic region for which we would borrow, on a secured basis of the lease asset, at an amount equal to the lease 
payments over a similar time period as the lease term.  We have no additional restrictions or covenants imposed by our lease 
contracts.

Asset Retirement Obligations

We record the fair value of an asset retirement obligation associated with the retirement of a tangible long-lived asset as 

a liability in the period incurred.  The liability is measured at discounted fair value and is adjusted to its present value in 
subsequent periods as accretion expense is recorded.  The corresponding asset retirement costs are capitalized as part of the 
carrying amount of the related long-lived asset and depreciated over the asset’s useful life.  Asset retirement obligations are 
reviewed annually in the fourth quarter and/or when circumstances or other events indicate that changes underlying retirement 
assumptions may have occurred.

The activities of our asset retirement obligations were as follows:

At December 31, 2019 and 2018, our consolidated balance sheets included an asset retirement obligation of $53.4 

million and $49.6 million, respectively, which were classified as other noncurrent liabilities.

In 2019, we had net adjustments that increased the asset retirement obligation by $4.5 million which was primarily 

comprised of increases in estimated costs for certain assets.

In 2018, we had net adjustments that increased the asset retirement obligation by $10.9 million which was primarily 

related to additional asset retirement obligations for leased assets.

Comprehensive Income (Loss) 

Accumulated other comprehensive loss consists of foreign currency translation adjustments, pension and postretirement 

liability adjustments, pension and postretirement amortization of prior service costs and actuarial losses and net unrealized 
(losses) gains on derivative contracts.

Goodwill

Goodwill is not amortized, but is reviewed for impairment annually in the fourth quarter and/or when circumstances or 
other events indicate that impairment may have occurred.  ASC 350 “Intangibles—Goodwill and Other” (ASC 350)  permits 
entities to make a qualitative assessment of whether it is more likely than not that a reporting unit’s fair value is less than its 
carrying amount before applying the two-step goodwill impairment test.  Circumstances that are considered as part of the 
qualitative assessment and could trigger the two-step impairment test include, but are not limited to:  a significant adverse 
change in the business climate; a significant adverse legal judgment; adverse cash flow trends; an adverse action or assessment 
by a government agency; unanticipated competition; sustained decline in our stock price; and a significant restructuring charge 
within a reporting unit.  We define reporting units at the business segment level or one level below the business segment 
level.  For purposes of testing goodwill for impairment, goodwill has been allocated to our reporting units to the extent it relates 
to each reporting unit. 

It is our practice, at a minimum, to perform a quantitative goodwill impairment test in the fourth quarter every three 

years.  In the fourth quarter of 2019, we performed our triennial quantitative goodwill impairment test for our reporting units.  
We use a discounted cash flow approach to develop the estimated fair value of a reporting unit when a quantitative test is 
performed.  Management judgment is required in developing the assumptions for the discounted cash flow model.  We also 
corroborate our discounted cash flow analysis by evaluating a market-based approach that considers earnings before interest, 
taxes, depreciation and amortization (EBITDA) multiples from a representative sample of comparable public companies.  As a 
further indicator that each reporting unit has been valued appropriately using a discounted cash flow model, the aggregate fair 
value of all reporting units is reconciled to the total market value of Olin.  An impairment would be recorded if the carrying 
amount of a reporting unit exceeded the estimated fair value.  Based on the aforementioned analysis, the estimated fair value of 
our reporting units exceeded the carrying value of the reporting units.  No impairment charges were recorded for 2019, 2018 or 
2017.

The discount rate, profitability assumptions and terminal growth rate of our reporting units and the cyclical nature of the 
chlor alkali industry were the material assumptions utilized in the discounted cash flow model used to estimate the fair value of 
each reporting unit.  The discount rate reflects a weighted-average cost of capital, which is calculated based on observable 
market data.  Some of this data (such as the risk free or treasury rate and the pretax cost of debt) are based on the market data at 
a point in time.  Other data (such as the equity risk premium) are based upon market data over time for a peer group of 
companies in the chemical manufacturing or distribution industries with a market capitalization premium added, as applicable.

The discounted cash flow analysis requires estimates, assumptions and judgments about future events.  Our analysis uses 
our internally generated long-range plan.  Our discounted cash flow analysis uses the assumptions in our long-range plan about 
terminal growth rates, forecasted capital expenditures and changes in future working capital requirements to determine the 
implied fair value of each reporting unit.  The long-range plan reflects management judgment, supplemented by independent 
chemical industry analyses which provide multi-year industry operating and pricing forecasts.

We believe the assumptions used in our goodwill impairment analysis are appropriate and result in reasonable estimates 
of the implied fair value of each reporting unit.  However, given the economic environment and the uncertainties regarding the 
impact on our business, there can be no assurance that our estimates and assumptions, made for purposes of our goodwill 
impairment testing, will prove to be an accurate prediction of the future.  In order to evaluate the sensitivity of the fair value 
calculation on the goodwill impairment test, we applied a hypothetical 10% decrease to the fair value of each reporting unit.  
We also applied a hypothetical decrease of 100-basis points in our terminal growth rate or an increase of 100-basis points in our 
weighted-average cost of capital to test the fair value calculation.  In all cases, the estimated fair value of our reporting units 
derived in these sensitivity calculations exceeded the carrying value in excess of 10%.  If our assumptions regarding future 
performance are not achieved, we may be required to record goodwill impairment charges in future periods.  It is not possible 
at this time to determine if any such future impairment charge would result or, if it does, whether such charge would be 
material.

Intangible Assets

In conjunction with our acquisitions, we have obtained access to the customer contracts and relationships, trade names, 

acquired technology and other intellectual property of the acquired companies.  These relationships are expected to provide 
economic benefit for future periods.  Amortization expense is recognized on a straight-line basis over the estimated lives of the 
related assets.  The amortization period of customer contracts and relationships, trade names, acquired technology and other 
intellectual property represents our best estimate of the expected usage or consumption of the economic benefits of the acquired 
assets, which is based on the company’s historical experience.

67

Table of Contents

Intangible assets with finite lives are reviewed for impairment when conditions indicate that the carrying values of the 

assets may not be recoverable.  Circumstances that are considered as part of the qualitative assessment and could trigger a 
quantitative impairment test include, but are not limited to:  a significant adverse change in the business climate; a significant 
adverse legal judgment including asset specific factors; adverse cash flow trends; an adverse action or assessment by a 
government agency; unanticipated competition; sustained decline in our stock price; and a significant restructuring charge 
within a reporting unit.  Based upon our qualitative assessment, it is more likely than not that the fair value of our intangible 
assets are greater than the carrying amount as of December 31, 2019.  No impairment of our intangible assets were recorded in 
2019, 2018 or 2017.

Environmental Liabilities and Expenditures

Accruals (charges to income) for environmental matters are recorded when it is probable that a liability has been 
incurred and the amount of the liability can be reasonably estimated, based upon current law and existing technologies.  These 
amounts, which are not discounted and are exclusive of claims against third parties, are adjusted periodically as assessment and 
remediation efforts progress or additional technical or legal information becomes available.  Environmental costs are 
capitalized if the costs increase the value of the property and/or mitigate or prevent contamination from future operations.

Income Taxes

Deferred taxes are provided for differences between the financial statement and tax basis of assets and liabilities using 
enacted tax rates in effect for the year in which the differences are expected to reverse.  A valuation allowance is provided to 
offset deferred tax assets if, based on the available evidence, it is more likely than not that some or all of the value of the 
deferred tax assets will not be realized.

Derivative Financial Instruments

We are exposed to market risk in the normal course of our business operations due to our purchases of certain 

commodities, our ongoing investing and financing activities and our operations that use foreign currencies.  The risk of loss can 
be assessed from the perspective of adverse changes in fair values, cash flows and future earnings.  We have established 
policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to 
such risks.  We use hedge accounting treatment for a significant amount of our business transactions whose risks are covered 
using derivative instruments.  The hedge accounting treatment provides for the deferral of gains or losses on derivative 
instruments until such time as the related transactions occur.

Concentration of Credit Risk

Accounts receivable is the principal financial instrument which subjects us to a concentration of credit risk.  Credit is 

extended based upon the evaluation of a customer’s financial condition and, generally, collateral is not required.  
Concentrations of credit risk with respect to receivables are somewhat limited due to our large number of customers, the 
diversity of these customers’ businesses and the geographic dispersion of such customers.  Our accounts receivable are 
predominantly derived from sales denominated in USD or the Euro.  We maintain an allowance for doubtful accounts based 
upon the expected collectibility of all trade receivables.

Fair Value

Fair value is defined as the price at which an asset could be exchanged in a current transaction between knowledgeable, 

willing parties or the amount that would be paid to transfer a liability to a new obligor, not the amount that would be paid to 
settle the liability with the creditor.  Where available, fair value is based on observable market prices or parameters or derived 
from such prices or parameters.  Where observable prices or inputs are not available, valuation models are applied.  These 
valuation techniques involve some level of management estimation and judgment, the degree of which is dependent on the 
price transparency for the instruments or market and the instruments’ complexity.

68

Table of Contents

Assets and liabilities recorded at fair value in the consolidated balance sheets are categorized based upon the level of 

judgment associated with the inputs used to measure their fair value.  Hierarchical levels, defined by ASC 820 “Fair Value 
Measurement” (ASC 820), and directly related to the amount of subjectivity associated with the inputs to fair valuation of these 
assets and liabilities, are as follows:

Level 1 — Inputs were unadjusted, quoted prices in active markets for identical assets or liabilities at the 
measurement date.

Level 2 — Inputs (other than quoted prices included in Level 1) were either directly or indirectly observable for 
the asset or liability through correlation with market data at the measurement date and for the duration of the 
instrument’s anticipated life.

Level 3 — Inputs reflected management’s best estimate of what market participants would use in pricing the 
asset or liability at the measurement date.  Consideration was given to the risk inherent in the valuation 
technique and the risk inherent in the inputs to the model.

Retirement-Related Benefits

We account for our defined benefit pension plans and non-pension postretirement benefit plans using actuarial models 

required by ASC 715 “Compensation—Retirement Benefits” (ASC 715).  These models use an attribution approach that 
generally spreads the financial impact of changes to the plan and actuarial assumptions over the average remaining service lives 
of the employees in the plan.  Changes in liability due to changes in actuarial assumptions such as discount rate, rate of 
compensation increases and mortality, as well as annual deviations between what was assumed and what was experienced by 
the plan are treated as actuarial gains or losses.  The principle underlying the required attribution approach is that employees 
render service over their average remaining service lives on a relatively smooth basis and, therefore, the accounting for benefits 
earned under the pension or non-pension postretirement benefits plans should follow the same relatively smooth pattern.   
Substantially all domestic defined benefit pension plan participants are no longer accruing benefits; therefore, actuarial gains 
and losses are amortized based upon the remaining life expectancy of the inactive plan participants.  For both the years ended 
December 31, 2019 and 2018, the average remaining life expectancy of the inactive participants in the domestic defined benefit 
pension plan were 18 years, respectively.

One of the key assumptions for the net periodic pension calculation is the expected long-term rate of return on plan 
assets, used to determine the “market-related value of assets.”  The “market-related value of assets” recognizes differences 
between the plan’s actual return and expected return over a five year period.  The required use of an expected long-term rate of 
return on the market-related value of plan assets may result in recognized pension income that is greater or less than the actual 
returns of those plan assets in any given year.  Over time, however, the expected long-term returns are designed to approximate 
the actual long-term returns and, therefore, result in a pattern of income and expense recognition that more closely matches the 
pattern of the services provided by the employees.  As differences between actual and expected returns are recognized over five 
years, they subsequently generate gains and losses that are subject to amortization over the average remaining life expectancy 
of the inactive plan participants, as described in the preceding paragraph.

We use long-term historical actual return information, the mix of investments that comprise plan assets, and future 
estimates of long-term investment returns and inflation by reference to external sources to develop the expected long-term rate 
of return on plan assets as of December 31.

The discount rate assumptions used for pension and non-pension postretirement benefit plan accounting reflect the rates 

available on high-quality fixed-income debt instruments on December 31 of each year.  The rate of compensation increase is 
based upon our long-term plans for such increases.  For retiree medical plan accounting, we review external data and our own 
historical trends for healthcare costs to determine the healthcare cost trend rates.

For our defined benefit pension and other postretirement benefit plans, we measure service and interest costs by applying 

the specific spot rates along the yield curve to the plans’ estimated cash flows.  We believe this approach provides a more 
precise measurement of service and interest costs by aligning the timing of the plans’ liability cash flows to the corresponding 
spot rates on the yield curve. 

Stock-Based Compensation

69

Table of Contents

We measure the cost of employee services received in exchange for an award of equity instruments, such as stock 
options, performance shares and restricted stock, based on the grant-date fair value of the award.  This cost is recognized over 
the period during which an employee is required to provide service in exchange for the award, the requisite service period 
(usually the vesting period).  An initial measurement is made of the cost of employee services received in exchange for an 
award of liability instruments based on its current fair value and the value of that award is subsequently remeasured at each 
reporting date through the settlement date.  Changes in fair value of liability awards during the requisite service period are 
recognized as compensation cost over that period.

The fair value of each option granted, which typically vests ratably over three years, but not less than one year, was 

estimated on the date of grant, using the Black-Scholes option-pricing model with the following assumptions:

Dividend yield
Risk-free interest rate
Expected volatility
Expected life (years)
Weighted-average grant fair value (per option)
Weighted-average exercise price
Shares granted

Dividend yield was based on our current dividend yield as of the option grant date.  Risk-free interest rate was based on 
zero coupon U.S. Treasury securities rates for the expected life of the options.  Expected volatility was based on our historical 
stock price movements, as we believe that historical experience is the best available indicator of the expected volatility.  
Expected life of the option grant was based on historical exercise and cancellation patterns, as we believe that historical 
experience is the best estimate for future exercise patterns.

Share Repurchases

On April 26, 2018, our board of directors authorized a share repurchase program for the purchase of shares of common 

stock at an aggregate price of up to $500.0 million.  This program will terminate upon the purchase of $500.0 million of our 
common stock.  Under our April 26, 2018 share repurchase program, we may pursue various share repurchase strategies, which 
include entering into accelerated share repurchase (ASR) agreements with third-party financial institutions to repurchase shares 
of Olin’s common stock.  Under an ASR agreement, Olin pays a specified amount to the financial institution and receives an 
initial delivery of shares.  This initial delivery of shares represents the minimum number of shares that Olin may receive under 
the agreement.  Upon settlement of the ASR agreement, the financial institution delivers additional shares, with the final 
number of shares delivered determined with reference to the volume weighted-average price of Olin’s common stock over the 
term of the agreement, less an agreed-upon discount.  The transactions are accounted for as liability or equity transactions and 
also as share retirements, similar to our other share repurchase activity, when the shares are received, at which time there is an 
immediate reduction in the weighted-average common shares calculation for basic and diluted earnings per share.

NOTE 3.  RECENT ACCOUNTING PRONOUNCEMENTS

In December 2019, the FASB issued ASU 2019-12, “Simplifying the Accounting for Income Taxes” which amends ASC 

740 “Income Taxes” (ASC 740).  This update is intended to simplify accounting for income taxes by removing certain 
exceptions to the general principles in ASC 740 and amending existing guidance to improve consistent application of ASC 740.  
This update is effective for fiscal years beginning after December 15, 2020 and interim periods within those fiscal years.  The 
guidance in this update has various elements, some of which are applied on a prospective basis and others on a retrospective 
basis with earlier application permitted.  We adopted this update on January 1, 2020 which did not have a material impact on 
our consolidated financial statements.

Table of Contents

In January 2017, the FASB issued ASU 2017-04, “Simplifying the Test for Goodwill Impairment” which amends ASC 
350.  This update will simplify the measurement of goodwill impairment by eliminating Step 2 from the goodwill impairment 
test.  This update will require an entity to perform its annual, or interim, goodwill impairment test by comparing the fair value 
of a reporting unit with its carrying amount and recognize an impairment charge for the amount by which the carrying amount 
exceeds the reporting unit’s fair value.  The update does not modify the option to perform the qualitative assessment for a 
reporting unit to determine if the quantitative impairment test is necessary.  This update is effective for fiscal years beginning 
after December 15, 2019, and interim periods within those fiscal years.  The guidance in this update is applied on a prospective 
basis, with earlier application permitted.  We adopted this update on January 1, 2020 which did not have a material impact on 
our consolidated financial statements.

In June 2016, the FASB issued ASU 2016-13, “Measurement of Credit Losses on Financial Instruments,” (ASU 
2016-03) which amends ASC 326 “Financial Instruments—Credit Losses.”  Subsequent to the issuance of ASU 2016-13, ASC 
326 was amended by various updates that amend and clarify the impact and implementation of the aforementioned update.  The 
new guidance introduces the current expected credit loss (CECL) model, which will require an entity to record an allowance for 
credit losses for certain financial instruments and financial assets, including trade receivables, based on expected losses rather 
than incurred losses.  Under this update, on initial recognition and at each reporting period, an entity will be required to 
recognize an allowance that reflects the entity’s current estimate of credit losses expected to be incurred over the life of the 
financial instrument.  This update is effective for fiscal years beginning after December 15, 2019, and interim periods within 
those fiscal years.  The guidance in this update has various elements, some of which are applied on a prospective basis and 
others on a retrospective basis, with earlier application permitted.  We adopted this update on January 1, 2020 which did not 
have a material impact on our consolidated financial statements and related disclosures.

In February 2016, the FASB issued ASU 2016-02 “Leases,” (ASU 2016-02) which supersedes ASC 840 “Leases” and 
creates a new topic, ASC 842 “Leases” (ASC 842).  Subsequent to the issuance of ASU 2016-02, ASC 842 was amended by 
various updates that amend and clarify the impact and implementation of the aforementioned update.  These updates require 
lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 
months on its balance sheet.  Upon initial application, the provisions of these updates are required to be applied using the 
modified retrospective method which requires retrospective adoption to each prior reporting period presented with the 
cumulative effect of adoption recorded to the earliest reporting period presented.  An optional transition method can be utilized 
which requires application of these updates beginning on the date of adoption with the cumulative effect of initially applying 
these updates recognized at the date of initial adoption.  These updates also expand the required quantitative and qualitative 
disclosures surrounding leases.  These updates are effective for fiscal years beginning after December 15, 2018 and interim 
periods within those fiscal years, with earlier application permitted.  We adopted these updates on January 1, 2019 using the 
optional transition method.  Accordingly, prior periods were not retrospectively adjusted.  Adoption of these updates resulted in 
the recording of operating lease assets and lease liabilities on our consolidated balance sheet of $291.9 million as of January 1, 
2019. Our assets and liabilities for finance leases remained unchanged.  We also recognized the cumulative effect of applying 
these updates as an adjustment to retained earnings of $11.2 million, net of tax, which was primarily related to the recognition 
of previously deferred sale/leaseback gains.  Our consolidated statements of operations and cash flows, along with our 
compliance with all covenants and restrictions under all our outstanding credit agreements, were not impacted by this adoption.  
These updates also impacted our accounting policies, internal controls and disclosures related to leases.  Expanded disclosures 
regarding leases are included in Note 23 “Leases”.

NOTE 4.  ACQUISITION

On October 5, 2015 (the Closing Date), we completed the acquisition (the Acquisition) from The Dow Chemical 
Company (Dow) of its U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics and Global Epoxy businesses (collectively, 
the Acquired Business), whose operating results are included in the accompanying financial statements since the Closing Date.

For the years ended December 31, 2018 and 2017, we incurred costs related to the integration of the Acquired Business 

of $1.0 million and $12.8 million, respectively, which consisted of advisory, legal, accounting and other professional fees.

NOTE 5.  RESTRUCTURING CHARGES

On December 11, 2019, we announced that we had made the decision to permanently close a chlor alkali plant with a 

capacity of 230,000 tons and our vinylidene chloride (VDC) production facility, both in Freeport, TX.  These closures are 
expected to be completed before the end of 2020.  For the year ended December 31, 2019, we recorded pretax restructuring 
charges of $58.9 million for non-cash impairment of equipment and facilities related to these actions.  We expect to incur 
additional restructuring charges through 2024 of approximately $50 million related to these actions.

On December 10, 2018, we announced that we had made the decision to permanently close the ammunition assembly 

operations at our Winchester facility in Geelong, Australia.  Subsequent to the facility’s closure, products for customers in the 
region are sourced from Winchester manufacturing facilities located in the United States.  For the years ended December 31, 
2019 and 2018, we recorded pretax restructuring charges of $0.4 million and $4.1 million, respectively for the write-off of 
equipment and facility costs, employee severance and related benefit costs, lease and other contract termination costs and 
facility exit costs related to this action.  For the year ended December 31, 2019, we also recorded additional pretax restructuring 
charges of $1.4 million for employee severance and related benefit costs related to our Winchester operations.

On March 21, 2016, we announced that we had made the decision to close a combined total of 433,000 tons of chlor 
alkali capacity across three separate locations.  Associated with this action, we have permanently closed our Henderson, NV 
chlor alkali plant with 153,000 tons of capacity and have reconfigured the site to manufacture bleach and distribute caustic soda 
and hydrochloric acid.  Also, the capacity of our Niagara Falls, NY chlor alkali plant has been reduced from 300,000 tons to 
240,000 tons and the chlor alkali capacity at our Freeport, TX facility was reduced by 220,000 tons.  This 220,000 ton 
reduction was entirely from diaphragm cell capacity.  For the years ended December 31, 2019, 2018 and 2017, we recorded 
pretax restructuring charges of $15.8 million, $15.7 million and $32.6 million, respectively, for the write-off of equipment and 
facility costs, lease and other contract termination costs, employee severance and related benefit costs, employee relocation 
costs and facility exit costs related to these actions.  We expect to incur additional restructuring charges through 2020 of 
approximately $5 million related to these capacity reductions.

For the years ended December 31, 2018 and 2017, we recorded pretax restructuring charges of $2.1 million and $3.3 

million, respectively, for lease and other contract termination costs and facility exit costs related to our permanent reduction in 
capacity at our Becancour, Canada chlor alkali facility in 2014.  

For the year ended December 31, 2017, we recorded pretax restructuring charges of $1.7 million for employee severance 

and related benefit costs related to the relocation of our Winchester centerfire pistol and rifle ammunition manufacturing 
operations from East Alton, IL to Oxford, MS that was announced in 2010 and completed in 2016.

NOTE 6.  EARNINGS PER SHARE

Basic and diluted net (loss) income per share are computed by dividing net (loss) income by the weighted-average 

number of common shares outstanding.  Diluted net (loss) income per share reflects the dilutive effect of stock-based 
compensation.

The computation of dilutive shares from stock-based compensation does not include 7.8 million, 2.4 million and 1.6 

million shares in 2019, 2018 and 2017, respectively, as their effect would have been anti-dilutive.

NOTE 7.  ACCOUNTS RECEIVABLES

On July 16, 2019, our existing $250.0 million Receivables Financing Agreement was extended to July 15, 2022 and 

downsized to $10.0 million with the option to expand to $300.0 million (Receivables Financing Agreement).  The 
administrative agent for our Receivables Financing Agreement is PNC Bank, National Association.  Under the Receivables 
Financing Agreement, our eligible trade receivables are used for collateralized borrowings and continue to be serviced by us.  
In addition, the Receivables Financing Agreement incorporates the leverage and coverage covenants that are contained in the 
$2,000.0 million senior credit facility.  For the year ended December 31, 2019, the outstanding balance of the $250.0 million 
Receivables Financing Agreement of $150.0 million was repaid with proceeds from the issuance of $750.0 million senior notes 
due 2029.  As of December 31, 2019 and 2018, we had zero and $125.0 million, respectively, drawn under the agreement.  As 
of December 31, 2019, we had $10.0 million of additional borrowing capacity under the Receivables Financing Agreement.

Olin also has trade accounts receivable factoring arrangements (AR Facilities) and pursuant to the terms of the AR 
Facilities, certain of our subsidiaries may sell their accounts receivable up to a maximum of $315.0 million.  We will continue 

73

Table of Contents

to service the outstanding accounts sold.  These receivables qualify for sales treatment under ASC 860 “Transfers and 
Servicing” and, accordingly, the proceeds are included in net cash provided by operating activities in the consolidated 
statements of cash flows.  The following table summarizes the AR Facilities activity:

operations.  The factoring discount for the years ended December 31, 2019, 2018 and 2017 was $2.9 million, $4.3 million and 
$3.7 million, respectively.  The agreements are without recourse and therefore no recourse liability has been recorded as of 
December 31, 2019.

At December 31, 2019 and 2018, our consolidated balance sheets included other receivables of $87.4 million and $58.0 

million, respectively, which were classified as receivables, net.

Inventories valued using the LIFO method comprised 56% and 55% of the total inventories at December 31, 2019 and

On January 1, 2019, we sold our 9.1% limited partnership interest in Bay Gas Storage Company, Ltd. (Bay Gas) for 

$20.0 million.  The sale closed on February 7, 2019 which resulted in a gain of $11.2 million for the year ended December 31, 
2019 which was recorded to other income in the consolidated statements of operations.

For the year ended December 31, 2018, we recorded a $21.5 million non-cash impairment charge related to an 
adjustment to the value of our 9.1% limited partnership interest in Bay Gas.  Bay Gas owns, leases and operates underground 
gas storage and related pipeline facilities, which are used to provide storage in the McIntosh, AL area and delivery of natural 
gas.  The general partner, Sempra Energy (Sempra), announced in the second quarter of 2018 its plan to sell several assets 
including its 90.9% interest in Bay Gas.  In connection with this decision, Sempra recorded an impairment charge related to 
Bay Gas adjusting the related assets’ carrying values to an estimated fair value.  We recorded a reduction in our investment in 
the non-consolidated affiliate for the proportionate share of the non-cash impairment charge.  Olin has no other non-
consolidated affiliates.

The losses of non-consolidated affiliates were $19.7 million for the year ended December 31, 2018, which reflect the 

$21.5 million non-cash impairment charge.  The earnings of non-consolidated affiliates were $1.8 million for the year ended 
December 31, 2017.

In connection with the Acquisition, Olin and Dow entered into arrangements for the long-term supply of ethylene by 
Dow to Olin, pursuant to which, among other things, Olin made upfront payments of $433.5 million on the Closing Date in 
order to receive ethylene at producer economics and for certain reservation fees and for the option to obtain additional ethylene 
at producer economics.  The fair value of the long-term supply contracts recorded as of the Closing Date was a long-term asset 
of $416.1 million which will be amortized over the life of the contracts as ethylene is received.  During 2017, we made an 
additional payment of $209.4 million in connection with our option to reserve additional ethylene supply at producer 
economics from Dow which increased the value of the long-term asset. 

 On February 27, 2017, we exercised the remaining option to reserve additional ethylene at producer economics from 

Dow.  In connection with the exercise of this option, we also secured a long-term customer arrangement.  As a result, an 
additional payment will be made to Dow that is not to exceed $493 million on or about the fourth quarter of 2020.  During 
2017, as a result of Dow’s new Texas 9 ethylene cracker becoming operational, Olin recognized a long-term asset and other 
liability of $389.2 million, which represented the present value of the additional estimated payment.  During 2019, Olin 
increased the long-term asset and other liability by $50.7 million.  The discounted amount of $52.7 million will be recorded as 
interest expense through the fourth quarter of 2020.  For the years ended December 31, 2019, 2018, and 2017 interest expense 
of $17.0 million, $16.0 million and $3.9 million, respectively, was recorded for accretion on the 2020 payment discount.

The weighted-average useful life of long-term supply contracts at December 31, 2019 was 20 years.  For the years ended 
December 31, 2019, 2018 and 2017, amortization expense of $37.6 million, $37.6 million and $28.2 million, respectively, was 
recognized within cost of goods sold related to these supply contracts and is reflected in depreciation and amortization on the 
consolidated statements of cash flows.  We estimate that amortization expense will be approximately $38 million in 2020 and 
$60 million in 2021, 2022, 2023 and 2024 related to these long-term supply contracts.  The long-term supply contracts are 
monitored for impairment each reporting period.

On July 16, 2019, Olin issued $750.0 million aggregate principal amount of 5.625% senior notes due August 1, 2029 

(2029 Notes), which were registered under the Securities Act of 1933, as amended.  Interest on the 2029 Notes began accruing 
from July 16, 2019 and is payable semi-annually beginning on February 1, 2020.  Proceeds from the 2029 Notes were used to 
redeem the remaining balance of the $1,375.0 million term loan facility of $493.0 million and $150.0 million of the 
Receivables Financing Agreement. 

On July 16, 2019, Olin entered into a new five-year, $2,000.0 million senior credit facility (2019 Senior Credit Facility), 
which replaces the existing $1,975.0 million senior credit facility.  The 2019 Senior Credit Facility includes a senior unsecured 
delayed-draw term loan facility in an aggregate principal amount of up to $1,200.0 million (Delayed Draw Term Loan Facility).  
The Delayed Draw Term Loan Facility will be available on a delayed basis in up to three draws to be made on or prior to 
November 29, 2020.  The Delayed Draw Term Loan Facility includes principal amortization amounts payable beginning the 
quarter ending after the facility is borrowed upon at a rate of 5.0% per annum for the first two years, increasing to 7.5% per 
annum for the following year and to 10.0% per annum for the last two years.  We expect the proceeds from the Delayed Draw 
Term Loan Facility will be used to redeem the 9.75% senior notes due 2023 and the 10.00% senior notes due 2025 on or about 
October 15, 2020.  The 2019 Senior Credit Facility also includes a senior unsecured revolving credit facility with aggregate 
commitments in an amount equal to $800.0 million (2019 Senior Revolving Credit Facility), which was increased from $600.0 
million.  The 2019 Senior Revolving Credit Facility includes a $100.0 million letter of credit subfacility.  For the year ended 
December 31, 2019, we had $796.5 million available under our 2019 Senior Revolving Credit Facility because we had 
issued $3.5 million of letters of credit.  The maturity date for the 2019 Senior Credit Facility is July 16, 2024 at which point all 
outstanding Delayed Draw Term Loan Facility and 2019 Senior Revolving Credit Facility balances will become due and 
payable.  In December 2019, Olin amended the 2019 Senior Credit Facility which amended the restrictive covenants of the 
agreement, including expanding the coverage and leverage ratios to be less restrictive over the next two and a half years.  

Under the 2019 Senior Credit Facility, we may select various floating rate borrowing options.  The actual interest rate 

paid on borrowings under the 2019 Senior Credit Facility is based on a pricing grid which is dependent upon the leverage ratio 
as calculated under the terms of the applicable facility for the prior fiscal quarter.  The 2019 Senior Credit Facility includes 

77

Table of Contents

various customary restrictive covenants, including restrictions related to the ratio of debt to earnings before interest expense, 
taxes, depreciation and amortization (leverage ratio) and the ratio of earnings before interest expense, taxes, depreciation and 
amortization to interest expense (coverage ratio).  Compliance with these covenants is determined quarterly based on operating 
cash flows.  We were in compliance with all covenants and restrictions under all our outstanding credit agreements as 
of December 31, 2019, and no event of default had occurred that would permit the lenders under our outstanding credit 
agreements to accelerate the debt if not cured.  In the future, our ability to generate sufficient operating cash flows, among other 
factors, will determine the amounts available to be borrowed under these facilities.  As of December 31, 2019, there were no 
covenants or other restrictions that would have limited our ability to borrow under these facilities.

For the year ended December 31, 2019, we recognized interest expense of $2.8 million for the write-off of unamortized 

deferred debt issuance costs related to the replacement of the existing $1,975.0 million senior credit facility, including the 
redemption of the remaining balance of the $1,375.0 million term loan facility, and the redemption of the remaining balance of 
and reduction in the borrowing capacity under the Receivables Financing Agreement. 

On January 19, 2018, Olin issued $550.0 million aggregate principal amount of 5.00% senior notes due February 1, 2030 

(2030 Notes), which were registered under the Securities Act of 1933, as amended.  Interest on the 2030 Notes began accruing 
from January 19, 2018 and is paid semi-annually beginning on August 1, 2018.  Proceeds from the 2030 Notes were used to 
redeem $550.0 million of debt under the $1,375.0 million term loan facility.  We recognized interest expense of $2.6 million for 
the write-off of unamortized deferred debt issuance costs related to this action in 2018.

On March 9, 2017, we entered into a five-year $1,975.0 million senior credit facility, which amended and restated the 

then existing $1,850.0 million senior credit facility.  We recognized interest expense of $1.2 million for the write-off of 
unamortized deferred debt issuance costs related to this action during 2017.  Pursuant to the agreement, the aggregate principal 
amount under the term loan facility was increased to $1,375.0 million, and the aggregate commitments under the senior 
revolving credit facility were increased to $600.0 million.  In March 2017, we drew the entire $1,375.0 million term loan 
facility and used the proceeds to redeem the remaining balance of the existing $1,350.0 million senior credit facility of $1,282.5 
million and a portion of the $800.0 million Sumitomo Credit Facility (Sumitomo Credit Facility).  For the year ended 
December 31, 2017, we repaid $51.6 million under the required quarterly installments of the $1,375.0 million term loan facility.

On March 9, 2017, Olin issued $500.0 million aggregate principal amount of 5.125% senior notes due September 15, 
2027 (2027 Notes), which were registered under the Securities Act of 1933, as amended.  Interest on the 2027 Notes began 
accruing from March 9, 2017 and is paid semi-annually beginning on September 15, 2017.  Proceeds from the 2027 Notes were 
used to redeem the remaining balance of the Sumitomo Credit Facility.  

During 2017, the remaining Sumitomo Credit Facility balance of $590.0 million was repaid using proceeds from the 

$1,975.0 million senior credit facility and the 2027 Notes.  We recognized interest expense of $1.5 million related to the write-
off of unamortized deferred debt issuance costs related to this action in 2017.

 In 2019, we paid debt issuance costs of $16.6 million for the issuance of the 2029 Notes and 2019 Senior Credit 
Facility.  In 2018, we paid debt issuance costs of $8.5 million relating to the 2030 Notes.  In 2017, we paid debt issuance costs 
of $11.2 million relating to the $1,975.0 million senior credit facility and the 2027 Notes. 

Pursuant to a note purchase agreement dated December 22, 1997, SunBelt sold $97.5 million of Guaranteed Senior 
Secured Notes due 2017, Series O, and $97.5 million of Guaranteed Senior Secured Notes due 2017, Series G.  We refer to 
these notes as the SunBelt Notes.  The SunBelt Notes accrued interest at a rate of 7.23% per annum, payable semi-annually in 
arrears on each June 22 and December 22.  In December 2017, $12.2 million was repaid on these SunBelt Notes.  At 
December 31, 2017, all amounts due under the SunBelt Notes had been repaid.

At December 31, 2019, we had total letters of credit of $68.7 million outstanding, of which $3.5 million were issued 

under our 2019 Senior Revolving Credit Facility.  The letters of credit are used to support certain long-term debt, certain 
workers compensation insurance policies, certain plant closure and post-closure obligations and certain international pension 
funding requirements.

Annual maturities of long-term debt, including finance lease obligations, are $2.1 million in 2020, $1.0 million in 2021, 

$200.7 million in 2022, $720.6 million in 2023, $70.7 million in 2024 and a total of $2,386.1 million thereafter.

In April 2016, we entered into three tranches of forward starting interest rate swaps whereby we agreed to pay fixed rates 

to the counterparties who, in turn, pay us floating rates on $1,100.0 million, $900.0 million and $400.0 million of our 
underlying floating-rate debt obligations.  Each tranche’s term length was for twelve months beginning on December 31, 2016, 
78

Table of Contents

2017 and 2018, respectively.  We designated the swaps as cash flow hedges of the risk of changes in interest payments 
associated with our variable-rate borrowings.  In July 2019, we terminated the remaining interest rate swap agreement which 
resulted in a gain of $1.8 million that was recognized in interest expense for the year ended December 31, 2019.  For the years 
ended December 31, 2019, 2018 and 2017, $4.3 million, $8.9 million and $3.1 million, respectively, of income was recorded to 
interest expense on the accompanying consolidated statements of operations related to these swap agreements.

In April 2016, we entered into interest rate swaps on $250.0 million of our underlying fixed-rate debt obligations, 
whereby we agreed to pay variable rates to the counterparties who, in turn, pay us fixed rates.  In October 2016, we entered into 
interest rate swaps on an additional $250.0 million of our underlying fixed-rate debt obligations, whereby we agreed to pay 
variable rates to the counterparties who, in turn, pay us fixed rates.  We designated the April 2016 and October 2016 interest 
rate swap agreements as fair value hedges of the risk of changes in the value of fixed-rate debt due to changes in interest rates 
for a portion of our fixed-rate borrowings.  In August 2019, we terminated the April 2016 and October 2016 interest rate swaps 
which resulted in a loss of $2.3 million that will be deferred as an offset to the carrying value of the related debt and will be 
recognized to interest expense through October 2025.  As of December 31, 2019, $2.2 million of this loss was included in long-
term debt in the consolidated balance sheet.  For the years ended December 31, 2019 and 2018, $2.6 million and $2.1 million, 
respectively, of expense and for the year ended December 31, 2017, $2.9 million of income was recorded to interest expense on 
the accompanying consolidated statements of operations related to these swap agreements. 

Our interest rate swaps reduced interest expense by $1.7 million, $6.8 million and $6.1 million in 2019, 2018 and 2017, 

respectively.  The difference between interest paid and interest received is included as an adjustment to interest expense.

NOTE 14.  PENSION PLANS

We sponsor domestic and foreign defined benefit pension plans for eligible employees and retirees.  Most of our 
domestic employees participate in defined contribution plans.  However,  a portion of our bargaining hourly employees 
continue to participate in our domestic qualified defined benefit pension plans under a flat-benefit formula.  Our funding policy 
for the qualified defined benefit pension plans is consistent with the requirements of federal laws and regulations.  Our foreign 
subsidiaries maintain pension and other benefit plans, which are consistent with local statutory practices.  

Our domestic qualified defined benefit pension plan provides that if, within three years following a change of control of 

Olin, any corporate action is taken or filing made in contemplation of, among other things, a plan termination or merger or 
other transfer of assets or liabilities of the plan, and such termination, merger or transfer thereafter takes place, plan benefits 
would automatically be increased for affected participants (and retired participants) to absorb any plan surplus (subject to 
applicable collective bargaining requirements).

During 2019, we made a discretionary cash contribution to our domestic qualified defined benefit pension plan of $12.5 
million.  Based on our plan assumptions and estimates, we will not be required to make any cash contributions to the domestic 
qualified defined benefit pension plan at least through 2020.

We have international qualified defined benefit pension plans to which we made cash contributions of $2.4 million, $2.6 

million and $1.7 million in 2019, 2018 and 2017, respectively, and we anticipate less than $5 million of cash contributions to 
international qualified defined benefit pension plans in 2020.

Under ASC 715, we recorded a $145.5 million after-tax charge ($177.7 million pretax) to shareholders’ equity as of 

December 31, 2019 for our pension plans.  This charge primarily reflected a 100-basis point decrease in the domestic pension 
plans’ discount rate, partially offset by favorable performance on plan assets during 2019.  In 2018, we recorded a $76.5 million 
after-tax charge ($100.6 million pretax) to shareholders’ equity as of December 31, 2018 for our pension plans.  This charge 
primarily reflected unfavorable performance on plan assets during 2018, partially offset by a 60-basis point increase in the 
domestic pension plans’ discount rate. 

The $364.1 million actuarial loss for 2019 was primarily due to a 100-basis point decrease in the domestic pension plans’ 

discount rate.  The $161.7 million actuarial gain for 2018 was primarily due to a 60-basis point increase in the domestic 
pension plans’ discount rate.

At December 31, 2019 and 2018, the benefit obligation of non-qualified pension plans was $5.8 million and $5.9 
million, respectively, and was included in the above pension benefit obligation.  There were no plan assets for these non-
qualified pension plans.  Benefit payments for the non-qualified pension plans are expected to be as follows:  2020—$0.8 
million; 2021—$0.5 million; 2022—$0.4 million; 2023—$0.4 million; and 2024—$0.2 million.  Benefit payments for the 
qualified plans are projected to be as follows:  2020—$146.9 million; 2021—$146.4 million; 2022—$146.3 million; 2023—

Pension Plan Assumptions

Certain actuarial assumptions, such as discount rate and long-term rate of return on plan assets, have a significant effect 

on the amounts reported for net periodic benefit cost and accrued benefit obligation amounts.  We use a measurement date of 
December 31 for our pension plans.

(1)   The discount rate—periodic benefit cost for our domestic qualified pension plan is comprised of the discount rate used to 

determine interest costs of 3.9% and the discount rate used to determine service costs of 4.3%.

The discount rate is based on a hypothetical yield curve represented by a series of annualized individual zero-coupon 

bond spot rates for maturities ranging from one-half to thirty years.  The bonds used in the yield curve must have a rating of AA 
or better per Standard & Poor’s, be non-callable, and have at least $250 million par outstanding.  The yield curve is then 
applied to the projected benefit payments from the plan.  Based on these bonds and the projected benefit payment streams, the 
single rate that produces the same yield as the matching bond portfolio is used as the discount rate.

The long-term expected rate of return on plan assets represents an estimate of the long-term rate of returns on the 
investment portfolio consisting of equities, fixed income and alternative investments.  We use long-term historical actual return 
information, the allocation mix of investments that comprise plan assets and forecast estimates of long-term investment returns, 
including inflation rates, by reference to external sources.  The historic rates of return on plan assets have been 7.3% for the last 
5 years, 8.8% for the last 10 years and 9.3% for the last 15 years.  The following rates of return by asset class were considered 
in setting the long-term rate of return assumption:

The Alternative Investments asset class includes hedge funds, real estate and private equity investments.  The Alternative 

Investments class is intended to help diversify risk and increase returns by utilizing a broader group of assets.

Absolute Return Strategies further diversify the plan’s assets through the use of asset allocations that seek to provide a 

targeted rate of return over inflation.  The investment managers allocate funds within asset classes that they consider to be 
undervalued in an effort to preserve gains in overvalued asset classes and to find opportunities in undervalued asset classes.

A master trust was established by our pension plan to accumulate funds required to meet benefit payments of our plan 

and is administered solely in the interest of our plan’s participants and their beneficiaries.  The master trust’s investment

horizon is long term.  Its assets are managed by professional investment managers or invested in professionally managed 
investment vehicles.

Our pension plan maintains a portfolio of assets designed to achieve an appropriate risk adjusted return.  The portfolio of 

assets is also structured to manage risk by diversifying assets across asset classes whose return patterns are not highly 
correlated, investing in passively and actively managed strategies and in value and growth styles, and by periodic rebalancing 
of asset classes, strategies and investment styles to objectively set targets.

As of December 31, 2019, the following target allocation and ranges have been set for each asset class:

U.S. equities—This class included actively and passively managed equity investments in common stock and 

commingled funds comprised primarily of large-capitalization stocks with value, core and growth strategies.

Non-U.S. equities—This class included actively managed equity investments in commingled funds comprised primarily 

of international large-capitalization stocks from both developed and emerging markets.

Fixed income and cash—This class included commingled funds comprised of debt instruments issued by the U.S. and 

Canadian Treasuries, U.S. Agencies, corporate debt instruments, asset- and mortgage-backed securities and cash.

Hedge fund of funds—This class included a hedge fund which invests in the following types of hedge funds:

Event driven hedge funds—This class included hedge funds that invest in securities to capture excess returns 
that are driven by market or specific company events including activist investment philosophies and the 
arbitrage of equity and private and public debt securities.

Market neutral hedge funds—This class included investments in U.S. and international equities and fixed 
income securities while maintaining a market neutral position in those markets.

Other hedge funds—This class primarily included long-short equity strategies and a global macro fund which 
invested in fixed income, equity, currency, commodity and related derivative markets.

Real estate funds—This class included several funds that invest primarily in U.S. commercial real estate.

Private equity funds—This class included several private equity funds that invest primarily in infrastructure and U.S. 

power generation and transmission assets.

Absolute return strategies—This class included multiple strategies which use asset allocations that seek to provide a 
targeted rate of return over inflation.  The investment managers allocate funds within asset classes that they consider to be 
undervalued in an effort to preserve gains in overvalued asset classes and to find opportunities in undervalued asset classes.  

U.S. equities and non-U.S. equities are primarily valued at the net asset value provided by the independent administrator 
or custodian of the commingled fund.  The net asset value is based on the value of the underlying equities, which are traded on 
an active market.  U.S. equities are also valued at the closing price reported in an active market on which the individual 

84

Table of Contents

securities are traded.  A portion of our fixed income investments are valued at the net asset value provided by the independent 
administrator or custodian of the fund.  The net asset value is based on the underlying assets, which are valued using inputs 
such as the closing price reported, if traded on an active market, values derived from comparable securities of issuers with 
similar credit ratings, or under a discounted cash flow approach that utilizes observable inputs, such as current yields of similar 
instruments, but includes adjustments for risks that may not be observable such as certain credit and liquidity risks.  Alternative 
investments are valued at the net asset value as determined by the independent administrator or custodian of the fund.  The net 
asset value is based on the underlying investments, which are valued using inputs such as quoted market prices of identical 
instruments, discounted future cash flows, independent appraisals and market-based comparable data.  Absolute return 
strategies are commingled funds which reflect the fair value of our ownership interest in these funds.  The investments in these 
commingled funds include some or all of the above asset classes and are primarily valued at net asset values based on the 
underlying investments, which are valued consistent with the methodologies described above for each asset class.

NOTE 15.  POSTRETIREMENT BENEFITS

We provide certain postretirement healthcare (medical) and life insurance benefits for eligible active and retired 
domestic employees.  The healthcare plans are contributory with participants’ contributions adjusted annually based on medical 
rates of inflation and plan experience.  We use a measurement date of December 31 for our postretirement plans.

The service cost component of net periodic postretirement benefit cost related to the employees of the operating 

segments are allocated to the operating segments based on their respective estimated census data.

Other Postretirement Benefits Plan Assumptions

Certain actuarial assumptions, such as discount rate, have a significant effect on the amounts reported for net periodic 

benefit cost and accrued benefit obligation amounts.

Discount rate—periodic benefit cost
Discount rate—benefit obligation

The discount rate is based on a hypothetical yield curve represented by a series of annualized individual zero-coupon 

bond spot rates for maturities ranging from one-half to thirty years.  The bonds used in the yield curve must have a rating of AA 
or better per Standard & Poor’s, be non-callable, and have at least $250 million par outstanding.  The yield curve is then 
applied to the projected benefit payments from the plan.  Based on these bonds and the projected benefit payment streams, the 
single rate that produces the same yield as the matching bond portfolio is used as the discount rate.

We review external data and our own internal trends for healthcare costs to determine the healthcare cost for the post 

retirement benefit obligation.  The assumed healthcare cost trend rates for pre-65 retirees were as follows:

Healthcare cost trend rate assumed for next year
Rate that the cost trend rate gradually declines to
Year that the rate reaches the ultimate rate

For post-65 retirees, we provide a fixed dollar benefit, which is not subject to escalation.

We expect to make payments of approximately $4 million for each of the next five years under the provisions of our 

other postretirement benefit plans.

The effective tax rate for 2019 included benefits associated with the finalization of the Internal Revenue Service (IRS) 

review of years 2013 to 2015 U.S. income tax claims, stock-based compensation, prior year tax positions, foreign tax law 
changes, a remeasurement of deferred taxes due to a decrease in our state effective tax rates and a change in tax contingencies.  
The effective tax rate also included expenses associated with a net increase in the valuation allowance primarily related to 
foreign deferred tax assets and liabilities.  These factors resulted in a net $19.4 million tax benefit.  After giving consideration 
to these items, the effective tax rate for 2019 of 16.8% was lower than the 21% U.S. federal statutory rate primarily due to state 
taxes and a net increase in the valuation allowance related to losses in foreign jurisdictions, partially offset by foreign income 
taxes and favorable permanent salt depletion deductions.

The effective tax rate for 2018 included benefits associated with the U.S. Tax Cuts and Jobs Act (2017 Tax Act), stock-

based compensation, changes in tax contingencies, a foreign dividend payment, changes associated with prior year tax positions 
and the remeasurement of deferred taxes due to a decrease in our state effective tax rates.  The effective tax rate also included 
expenses associated with a net increase in the valuation allowance related to deferred tax assets in foreign jurisdictions and the 
remeasurement of deferred taxes due to changes in our foreign tax rates.  These factors resulted in a net $2.9 million tax 
benefit, of which $3.8 million related to the increase of the 2017 Tax Act benefit.  After giving consideration to these items, the 
effective tax rate for 2018 of 25.7% was higher than the 21% U.S. federal statutory rate primarily due to state and foreign 
income taxes, foreign income inclusions and a net increase in the valuation allowance related to current year losses in foreign 
jurisdictions, partially offset by favorable permanent salt depletion deductions.

The effective tax rate for 2017 included benefits associated with the 2017 Tax Act, an agreement with the IRS on prior 

period tax examinations, stock based compensation, U.S. federal tax credits, changes to prior year tax positions and a reduction 
to the deferred tax liability on unremitted foreign earnings.  The effective tax rate also included an expense associated with a 
net increase in the valuation allowance, primarily related to foreign net operating losses and remeasurement of deferred taxes 
due to an increase in our state effective tax rates.  These factors resulted in a net $452.3 million tax benefit, of which $437.9 
million was a provisional benefit from the 2017 Tax Act.  After giving consideration to these items, the effective tax rate for 
2017 of 17.1% was lower than the 35% U.S. federal statutory rate, primarily due to favorable permanent salt depletion 
deductions.

Realization of the net deferred tax assets, irrespective of indefinite-lived deferred tax liabilities, is dependent on future 

reversals of existing taxable temporary differences and adequate future taxable income, exclusive of reversing temporary 
differences and carryforwards.  Although realization is not assured, we believe that it is more likely than not that the net 
deferred tax assets will be realized.

At December 31, 2019, we had deferred state tax benefits of $12.5 million relating to state NOLs, which are available to 

offset future state taxable income through 2038.

Table of Contents

At December 31, 2019, we had deferred state tax benefits of $20.3 million relating to state tax credits, which are 

available to offset future state tax liabilities through 2034.

At December 31, 2019, we had a capital loss carryforward of $3.6 million (representing $0.9 million of deferred tax 
assets) which is available to offset future consolidated capital gains that will expire in years 2020 through 2023, if not utilized.  

At December 31, 2019, we had foreign tax credits of $5.4 million, which are available to offset certain federal tax 

liabilities through 2029.

At December 31, 2019, we had NOLs of approximately $317.0 million (representing $57.5 million of deferred tax 

assets) in various foreign jurisdictions.  Of these, $58.1 million (representing $14.1 million of deferred tax assets) expire in 
various years from 2020 to 2039.  The remaining $258.9 million (representing $43.4 million of deferred tax assets) do not 
expire. 

As of December 31, 2019, we had recorded a valuation allowance of $182.1 million, compared to $147.4 million as of 

December 31, 2018.  The increase of $34.7 million is primarily due to the recent history of cumulative losses within foreign 
jurisdictions and projections of future taxable income insufficient to overcome the loss history.  We continue to have net 
deferred tax assets in several jurisdictions which we expect to realize, assuming sufficient taxable income can be generated to 
utilize these deferred tax benefits, which is based on certain estimates and assumptions.  If these estimates and related 
assumptions change in the future, we may be required to reduce the value of the deferred tax assets resulting in additional tax 
expense.

The activity of our deferred income tax valuation allowance was as follows:

Beginning balance

Increases to valuation allowances

Decreases to valuation allowances

Foreign currency translation adjustments

As of December 31, 2019, we had $22.8 million of gross unrecognized tax benefits, which would have a net $22.4 
million impact on the effective tax rate, if recognized.  As of December 31, 2018, we had $33.8 million of gross unrecognized 
tax benefits, which would have a net $33.0 million impact on the effective tax rate, if recognized.  The change for 2019 
primarily relates to additional gross unrecognized benefits for current and prior year tax positions, as well as decreases for prior 
year tax positions.  The change for 2018 primarily relates to additional gross unrecognized benefits for current and prior year 
tax positions, as well as decreases for prior year tax positions.  The amounts of unrecognized tax benefits were as follows:

Beginning balance

Increase for current year tax positions
Increase for prior year tax positions
Decrease for prior year tax positions
Decrease due to tax settlements

In July 2019, the review of certain U.S. income tax claims by the IRS for the years 2013 to 2015 was finalized which 

resulted in a $14.3 million income tax benefit primarily related to favorable adjustments in uncertain tax positions for prior tax 
years.

We recognize interest and penalty expense related to unrecognized tax positions as a component of the income tax 

provision.  As of December 31, 2019 and 2018, interest and penalties accrued were $0.1 million and $1.6 million, 
respectively.  For 2019, 2018 and 2017, we recorded (benefit) expense related to interest and penalties of $(1.5) million, $0.4 
million and $(1.8) million, respectively.

As of December 31, 2019, we believe it is reasonably possible that our total amount of unrecognized tax benefits will 

decrease by approximately $3.8 million over the next twelve months.  The anticipated reduction primarily relates to settlements 
with tax authorities and the expiration of federal, state and foreign statutes of limitation.

We operate globally and file income tax returns in numerous jurisdictions.  Our tax returns are subject to examination by 

various federal, state and local tax authorities.  Our 2016 U.S. federal income tax return is currently under examination by the 
IRS.  In connection with the October 5, 2015 acquisition of Dow’s U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics 
and Global Epoxy businesses, the prior owner of the businesses retained liabilities relating to taxes to the extent arising prior to 
October 5, 2015.  We believe we have adequately provided for all tax positions; however, amounts asserted by taxing 
authorities could be greater than our accrued position.  For our primary tax jurisdictions, the tax years that remain subject to 
examination are as follows:

U.S. federal income tax
U.S. state income tax
Canadian federal income tax
Brazil
Germany

NOTE 18.  CONTRIBUTING EMPLOYEE OWNERSHIP PLAN

The Contributing Employee Ownership Plan (CEOP) is a defined contribution plan available to essentially all domestic 
employees.  We provide a contribution to an individual retirement contribution account maintained with the CEOP equal to an 
amount of between 5.0% and 7.5% of the employee’s eligible compensation.  The defined contribution plan expense was $29.9 
million, $28.6 million and $29.0 million for 2019, 2018 and 2017, respectively.

Company matching contributions are invested in the same investment allocation as the employee’s contribution.  Our 
matching contributions for eligible employees amounted to $15.8 million, $14.9 million and $11.5 million in 2019, 2018 and 
2017, respectively.  Effective January 1, 2020, we suspended the match on all salaried and non-bargaining hourly employees’ 

90

Table of Contents

contributions, and moved to a discretionary contribution model with contributions contingent upon company-wide financial 
performance.

Employees generally become vested in the value of the contributions we make to the CEOP according to a schedule 
based on service.  After 2 years of service, participants are 25% vested.  They vest in increments of 25% for each additional 
year and after 5 years of service, they are 100% vested in the value of the contributions that we have made to their accounts.

Employees may transfer any or all of the value of the investments, including Olin common stock, to any one or 

combination of investments available in the CEOP.  Employees may transfer balances daily and may elect to transfer any 
percentage of the balance in the fund from which the transfer is made.  However, when transferring out of a fund, employees 
are prohibited from trading out of the fund to which the transfer was made for seven calendar days.  This limitation does not 
apply to trades into the money market fund or the Olin Common Stock Fund.

NOTE 19.  STOCK-BASED COMPENSATION

Stock-based compensation expense was allocated to the operating segments for the portion related to employees whose 

compensation would be included in cost of goods sold with the remainder recognized in corporate/other.  There were no 
significant capitalized stock-based compensation costs.  Stock-based compensation granted includes stock options, 
performance stock awards, restricted stock awards and deferred directors’ compensation.  Stock-based compensation expense 
was as follows:

Under the stock option and long-term incentive plans, options may be granted to purchase shares of our common stock at 

an exercise price not less than fair market value at the date of grant, and are exercisable for a period not exceeding ten years 
from that date.  Stock options, restricted stock and performance shares typically vest over three years.  We issue shares to settle 
stock options, restricted stock and share-based performance awards.  In 2019, 2018 and 2017, long-term incentive awards 
included stock options, performance share awards and restricted stock.  The stock option exercise price was set at the fair 
market value of common stock on the date of the grant, and the options have a ten-year term.

Performance share awards are denominated in shares of our stock and are paid half in cash and half in stock.  Payouts for 

performance share awards are based on two criteria: (1) 50% of the award is based on Olin’s total shareholder returns over the 
applicable three-year performance cycle in relation to the total shareholder return over the same period among a portfolio of 
public companies which are selected in concert with outside compensation consultants and (2) 50% of the award is based on 
Olin’s net income over the applicable three-year performance cycle in relation to the net income goal for such period as set by 
the compensation committee of Olin’s board of directors.  The expense associated with performance shares is recorded based 
on our estimate of our performance relative to the respective target.  If an employee leaves the company before the end of the 
performance cycle, the performance shares may be prorated based on the number of months of the performance cycle worked 
and are settled in cash instead of half in cash and half in stock when the three-year performance cycle is completed.

NOTE 20.  SHAREHOLDERS’ EQUITY

On April 26, 2018, our board of directors authorized a share repurchase program for the purchase of shares of common 

stock at an aggregate price of up to $500.0 million.  This program will terminate upon the purchase of $500.0 million of our 
common stock.

On August 5, 2019, we entered into an accelerated share repurchase (ASR) agreement with Goldman Sachs & Co. LLC, 
a third-party financial institution, to repurchase $100.0 million of Olin’s common stock.  This authorization was granted under 
the April 26, 2018 share repurchase program and reduced the remaining authorized repurchase amount under that program by 
$100.0 million.  In connection with this agreement, we repurchased a total of 5.7 million shares under this ASR agreement.

For the years ended December 31, 2019 and 2018, 8.0 million and 2.1 million shares, respectively, were repurchased and 
retired at a cost of $145.9 million and $50.0 million, respectively.  As of December 31, 2019, a cumulative total of 10.1 million 
shares were repurchased and retired at a cost of $195.9 million and $304.1 million of common stock remained authorized to be 
repurchased.

During 2019, 2018 and 2017, we issued 0.1 million, 0.2 million and 1.7 million shares, respectively, with a total value of 

$1.7 million, $3.4 million and $32.4 million, respectively, representing stock options exercised.  

We have registered an undetermined amount of securities with the SEC, so that, from time-to-time, we may issue debt 
securities, preferred stock and/or common stock and associated warrants in the public market under that registration statement.

In February 2018, the FASB issued ASU 2018-02, “Reclassification of Certain Tax Effects from Accumulated Other 

Comprehensive Income” (ASU 2018-02) which amends ASC 220 “Income Statement—Reporting Comprehensive Income.”  
This update allows a reclassification from accumulated other comprehensive loss to retained earnings for the stranded tax 
effects resulting from the 2017 Tax Act during each fiscal year or quarter in which the effect of the lower tax rate is recorded.  
We adopted this update in March 2018 and reclassified $85.9 million related to the deferred gain resulting from the 2017 Tax 
Act from accumulated other comprehensive loss to retained earnings.

NOTE 21.  SEGMENT INFORMATION

We define segment results as income (loss) before interest expense, interest income, other operating income (expense), 

non-operating pension income, other income (expense) and income taxes, and includes the operating results of non-
consolidated affiliates.  Consistent with the guidance in ASC 280 “Segment Reporting,” we have determined it is appropriate to 
include the operating results of non-consolidated affiliates in the relevant segment financial results.  We have three operating 
segments: Chlor Alkali Products and Vinyls, Epoxy and Winchester.  The three operating segments reflect the organization used 
by our management for purposes of allocating resources and assessing performance.  Chlorine used in our Epoxy segment is 
transferred at cost from the Chlor Alkali Products and Vinyls segment.  Sales and profits are recognized in the Chlor Alkali 
Products and Vinyls segment for all caustic soda generated and sold by Olin.

As is common in our industry, we are subject to environmental laws and regulations related to the use, storage, handling, 

generation, transportation, emission, discharge, disposal and remediation of, and exposure to, hazardous and non-hazardous 
substances and wastes in all of the countries in which we do business.  

The establishment and implementation of national, state or provincial and local standards to regulate air, water and land 

quality affect substantially all of our manufacturing locations around the world.  Laws providing for regulation of the 
manufacture, transportation, use and disposal of hazardous and toxic substances, and remediation of contaminated sites, have 
imposed additional regulatory requirements on industry, particularly the chemicals industry.  In addition, implementation of 
environmental laws has required and will continue to require new capital expenditures and will increase plant operating 
costs.  We employ waste minimization and pollution prevention programs at our manufacturing sites.  

In connection with the October 5, 2015 acquisition of Dow’s U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics 
and Global Epoxy businesses, the prior owner of the businesses retained liabilities relating to releases of hazardous materials 
and violations of environmental law to the extent arising prior to October 5, 2015.

We are party to various government and private environmental actions associated with past manufacturing facilities and 

former waste disposal sites.  Associated costs of investigatory and remedial activities are provided for in accordance with 
generally accepted accounting principles governing probability and the ability to reasonably estimate future costs.  Our ability 
to estimate future costs depends on whether our investigatory and remedial activities are in preliminary or advanced 
stages.  With respect to unasserted claims, we accrue liabilities for costs that, in our experience, we expect to incur to protect 
our interests against those unasserted claims.  Our accrued liabilities for unasserted claims amounted to $8.6 million at 
December 31, 2019.  With respect to asserted claims, we accrue liabilities based on remedial investigation, feasibility study, 
remedial action and operation, maintenance and monitoring (OM&M) expenses that, in our experience, we expect to incur in 
connection with the asserted claims.  Required site OM&M expenses are estimated and accrued in their entirety for required 
periods not exceeding 30 years, which reasonably approximates the typical duration of long-term site OM&M.

At December 31, 2019 and 2018, our consolidated balance sheets included environmental liabilities of $122.0 million 

and $108.6 million, respectively, which were classified as other noncurrent liabilities.  Our environmental liability amounts do 
not take into account any discounting of future expenditures or any consideration of insurance recoveries or advances in 
technology.  These liabilities are reassessed periodically to determine if environmental circumstances have changed and/or 
remediation efforts and our estimate of related costs have changed.  As a result of these reassessments, future charges to income 
may be made for additional liabilities.  Of the $139.0 million included on our consolidated balance sheet at December 31, 2019 
for future environmental expenditures, we currently expect to utilize $87.3 million of the reserve for future environmental 
expenditures over the next 5 years, $20.5 million for expenditures 6 to 10 years in the future, and $31.2 million for 
expenditures beyond 10 years in the future.

Our total estimated environmental liability at December 31, 2019 was attributable to 59 sites, 14 of which were United 

States Environmental Protection Agency National Priority List sites.  Nine sites accounted for 81% of our environmental 
liability and, of the remaining 50 sites, no one site accounted for more than 3% of our environmental liability.  At seven of the 
nine sites, part of the site is in the long-term OM&M stage.  At six of the nine sites, a remedial action plan is being developed 
for part of the site.  At five of the nine sites, a remedial design is being developed at part of the site and at four of the nine sites, 
part of the site is subject to a remedial investigation.  All nine sites are either associated with past manufacturing operations or 
former waste disposal sites.  None of the nine largest sites represents more than 20% of the liabilities reserved on our 
consolidated balance sheet at December 31, 2019 for future environmental expenditures.

Environmental provisions charged (credited) to income, which are included in cost of goods sold, were as follows:

Provisions charged to income for the year ended December 31, 2019 include a $20.0 million increase in costs at a former 
manufacturing site resulting from revised remediation estimates as a result of agency action during the second quarter of 2019.  

During 2018, we settled certain disputes with respect to insurance coverage for costs at various environmental 
remediation sites for $121.0 million.  Environmental expense (income) for the year ended December 31, 2018 include 
insurance recoveries for environmental costs incurred and expensed in prior periods of $111.0 million.  The recoveries are 
reduced by estimated liabilities of $10.0 million associated with claims by subsequent owners of certain of the settled 
environmental sites.  Environmental expense (income) for the year ended December 31, 2019 included $4.8 million of 
recoveries associated with resolving the outstanding third party claims against the proceeds from the 2018 environmental 
insurance settlement.  

These charges relate primarily to remedial and investigatory activities associated with past manufacturing operations and 

former waste disposal sites and may be material to operating results in future years.

Annual environmental-related cash outlays for site investigation and remediation are expected to range between 
approximately $15 million to $25 million over the next several years, which are expected to be charged against reserves 
recorded on our consolidated balance sheet.  While we do not anticipate a material increase in the projected annual level of our 

98

Table of Contents

environmental-related cash outlays for site investigation and remediation, there is always the possibility that such an increase 
may occur in the future in view of the uncertainties associated with environmental exposures.  Environmental exposures are 
difficult to assess for numerous reasons, including the identification of new sites, developments at sites resulting from 
investigatory studies, advances in technology, changes in environmental laws and regulations and their application, changes in 
regulatory authorities, the scarcity of reliable data pertaining to identified sites, the difficulty in assessing the involvement and 
financial capability of other Potentially Responsible Parties (PRPs), our ability to obtain contributions from other parties and 
the lengthy time periods over which site remediation occurs.  It is possible that some of these matters (the outcomes of which 
are subject to various uncertainties) may be resolved unfavorably to us, which could materially adversely affect our financial 
position or results of operations.  At December 31, 2019, we estimate that it is reasonably possible that we may have additional 
contingent environmental liabilities of $80 million in addition to the amounts for which we have already recorded as a reserve.

NOTE 23.  LEASES

Our lease commitments are primarily for railcars, but also include logistics, manufacturing, storage, real estate and 
information technology assets.  Our leases have remaining lease terms of up to 95 years, some of which may include options to 
extend the leases for up to five years, and some of which may include options to terminate the leases within one year.

The above purchase commitments include raw material, capital expenditure and utility purchasing commitments utilized 

in our normal course of business for our projected needs.  In connection with the Acquisition, certain additional agreements 
have been entered into with Dow, including, long-term purchase agreements for raw materials.  These agreements are 
maintained through long-term cost based contracts that provide us with a reliable supply of key raw materials.  Key raw 
materials received from Dow include ethylene, electricity, propylene and benzene.  On February 27, 2017, we exercised the 
remaining option to reserve additional ethylene at producer economics from Dow.  In connection with the exercise of this 
option, we also secured a long-term customer arrangement.  As a result, an additional payment will be made to Dow that is not 
to exceed $493 million on or about the fourth quarter of 2020.

We are party to a dispute relating to a contract at our Plaquemine, LA facility.  The other party to the contract filed a 

demand for arbitration alleging, among other things, that Olin breached the contract, and claims damages in excess of the 
amount Olin believes it is obligated to pay under the contract.  Olin asserted a counterclaim alleging it has been charged a fee in 
excess of what the contract permits.  The arbitration hearing was held during the fourth quarter 2019.  Although the timing is 
uncertain, we currently anticipate receiving a ruling during the first half of 2020.  Any additional losses related to this contract 
dispute are not currently estimable because of unresolved questions of fact and law but, if resolved unfavorably to Olin, they 
could have a material adverse effect on our financial position, cash flows or results of operations.

Olin and Oxy Vinyls, L.P. (Oxy) have a long-term chlorine supply agreement, which is the subject of a pricing dispute.  
The dispute is pending in the United States District Court for the Southern District of Texas.  Although the timing is uncertain, 
we currently anticipate that the case will proceed to trial during 2020.  Any additional losses related to this contract dispute are 
not currently estimable because of unresolved questions of fact and law but, if resolved unfavorably to Olin, they could have a 
material adverse effect on our financial position, cash flows or results of operations.

Olin, K.A. Steel Chemicals (a wholly owned subsidiary of Olin) and other caustic soda producers were named as 
defendants in six purported class action civil lawsuits filed March 22, 25 and 26, 2019 and April 12, 2019 in the U.S. District 
Court for the Western District of New York on behalf of the respective named plaintiffs and a putative class comprised of all 
persons and entities who purchased caustic soda in the U.S. directly from one or more of the defendants, their parents, 
predecessors, subsidiaries or affiliates at any time between October 1, 2015 and the present.  Olin, K.A. Steel Chemicals and 
other caustic soda producers were also named as defendants in two purported class action civil lawsuits filed July 25 and 29, 
2019 in the U.S. District Court for the Western District of New York on behalf of the respective named plaintiffs and a putative 
class comprised of all persons and entities who purchased caustic soda in the U.S. indirectly from distributors at any time 
between October 1, 2015 and the present.  The other defendants named in the lawsuits are Occidental Petroleum Corporation, 
Occidental Chemical Corporation d/b/a OxyChem, Westlake Chemical Corporation, Shin-Etsu Chemical Co., Ltd., Shintech 
Incorporated, Formosa Plastics Corporation, and Formosa Plastics Corporation, U.S.A.  The lawsuits allege the defendants 
conspired to fix, raise, maintain and stabilize the price of caustic soda, restrict domestic (U.S.) supply of caustic soda and 
allocate caustic soda customers.  Plaintiffs seek an unspecified amount of damages and injunctive relief.  We believe we have 
meritorious legal positions and will continue to represent our interests vigorously in this matter.  Any losses related to this 
matter are not currently estimable because of unresolved questions of fact and law, but if resolved unfavorably to Olin, could 
have a material adverse effect on our financial position, cash flows or results of operations.

Table of Contents

We, and our subsidiaries, are defendants in various other legal actions (including proceedings based on alleged 

exposures to asbestos) incidental to our past and current business activities.  At December 31, 2019 and 2018, our consolidated 
balance sheets included liabilities for these other legal actions of $12.4 million and $15.6 million, respectively.  These liabilities 
do not include costs associated with legal representation.  Based on our analysis, and considering the inherent uncertainties 
associated with litigation, we do not believe that it is reasonably possible that these other legal actions will materially adversely 
affect our financial position, cash flows or results of operations.  In connection with the October 5, 2015 acquisition of Dow’s 
U.S. Chlor Alkali and Vinyl, Global Chlorinated Organics and Global Epoxy businesses, the prior owner of the businesses 
retained liabilities related to litigation to the extent arising prior to October 5, 2015.  

During the ordinary course of our business, contingencies arise resulting from an existing condition, situation or set of 

circumstances involving an uncertainty as to the realization of a possible gain contingency.  In certain instances such as 
environmental projects, we are responsible for managing the clean-up and remediation of an environmental site.  There exists 
the possibility of recovering a portion of these costs from other parties.  We account for gain contingencies in accordance with 
the provisions of ASC 450 “Contingencies” and therefore do not record gain contingencies and recognize income until it is 
earned and realizable.

For the year ended December 31, 2018, we recognized an insurance recovery of $8.0 million in other operating income 

for a second quarter 2017 business interruption at our Freeport, TX vinyl chloride monomer facility. 

NOTE 25.  DERIVATIVE FINANCIAL INSTRUMENTS

We are exposed to market risk in the normal course of our business operations due to our purchases of certain 

commodities, our ongoing investing and financing activities and our operations that use foreign currencies.  The risk of loss can 
be assessed from the perspective of adverse changes in fair values, cash flows and future earnings.  We have established 
policies and procedures governing our management of market risks and the use of financial instruments to manage exposure to 
such risks.  ASC 815 requires an entity to recognize all derivatives as either assets or liabilities in the consolidated balance 
sheets and measure those instruments at fair value.  In accordance with ASC 815, we designate derivative contracts as cash 
flow hedges of forecasted purchases of commodities and forecasted interest payments related to variable-rate borrowings and 
designate certain interest rate swaps as fair value hedges of fixed-rate borrowings.  We do not enter into any derivative 
instruments for trading or speculative purposes.

Energy costs, including electricity and natural gas, and certain raw materials used in our production processes are subject 

to price volatility.  Depending on market conditions, we may enter into futures contracts, forward contracts, commodity swaps 
and put and call option contracts in order to reduce the impact of commodity price fluctuations.  The majority of our 
commodity derivatives expire within one year.  

We actively manage currency exposures that are associated with net monetary asset positions, currency purchases and 
sales commitments denominated in foreign currencies and foreign currency denominated assets and liabilities created in the 
normal course of business.  We enter into forward sales and purchase contracts to manage currency risk to offset our net 
exposures, by currency, related to the foreign currency denominated monetary assets and liabilities of our operations.  At 
December 31, 2019, we had outstanding forward contracts to buy foreign currency with a notional value of $140.6 million and 
to sell foreign currency with a notional value of $99.2 million.  All of the currency derivatives expire within one year and are 
for USD equivalents.  The counterparties to the forward contracts are large financial institutions; however, the risk of loss to us 
in the event of nonperformance by a counterparty could be significant to our financial position or results of operations.  At 
December 31, 2018, we had outstanding forward contracts to buy foreign currency with a notional value of $123.7 million and 
to sell foreign currency with a notional value of $82.6 million. 

Cash Flow Hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the change in fair value of the derivative 

is recognized as a component of other comprehensive income (loss) until the hedged item is recognized in earnings.

As of December 31, 2019, the counterparties to these commodity contracts were Wells Fargo Bank, N.A., Citibank, 

N.A., JPMorgan Chase Bank, National Association and Bank of America Corporation, all of which are major financial 
institutions. 

We use cash flow hedges for certain raw material and energy costs such as copper, zinc, lead, ethane, electricity and 

natural gas to provide a measure of stability in managing our exposure to price fluctuations associated with forecasted 
purchases of raw materials and energy used in our manufacturing process.  At December 31, 2019, we had open derivative 
contract positions through 2027.  If all open futures contracts had been settled on December 31, 2019, we would have 
recognized a pretax loss of $17.6 million.

If commodity prices were to remain at December 31, 2019 levels, approximately $12.7 million of deferred losses, net of 

tax, would be reclassified into earnings during the next twelve months.  The actual effect on earnings will be dependent on 
actual commodity prices when the forecasted transactions occur.

We use interest rate swaps as a means of minimizing cash flow fluctuations that may arise from volatility in interest rates 

of our variable-rate borrowings.  In April 2016, we entered into three tranches of forward starting interest rate swaps whereby 
we agreed to pay fixed rates to the counterparties who, in turn, pay us floating rates on $1,100.0 million, $900.0 million and 
$400.0 million of our underlying floating-rate debt obligations.  Each tranche’s term length was for twelve months beginning 
on December 31, 2016, 2017 and 2018, respectively.  We have designated the swaps as cash flow hedges of the risk of changes 
in interest payments associated with our variable-rate borrowings.  In July 2019, we terminated the remaining interest rate swap 
agreement which resulted in a gain of $1.8 million that was recognized in interest expense for the year ended December 31, 
2019.  For the years ended December 31, 2019, 2018 and 2017, $4.3 million, $8.9 million and $3.1 million, respectively, of 
income was recorded to interest expense on the accompanying consolidated statements of operations related to these swap 
agreements.

 Fair Value Hedges

We use interest rate swaps as a means of managing interest expense and floating interest rate exposure to optimal 

levels.  For derivative instruments that are designated and qualify as a fair value hedge, the gain or loss on the derivative as 
well as the offsetting loss or gain on the hedged item attributable to the hedged risk are recognized in current earnings.  We 
include the gain or loss on the hedged items (fixed-rate borrowings) in the same line item, interest expense, as the offsetting 
loss or gain on the related interest rate swaps.  As of December 31, 2019 and 2018, the total notional amounts of our interest 
rate swaps designated as fair value hedges were zero and $500.0 million, respectively.

In April 2016, we entered into interest rate swaps on $250.0 million of our underlying fixed-rate debt obligations, 
whereby we agreed to pay variable rates to the counterparties who, in turn, pay us fixed rates.  In October 2016, we entered into 
interest rate swaps on an additional $250.0 million of our underlying fixed-rate debt obligations, whereby we agreed to pay 
variable rates to the counterparties who, in turn, pay us fixed rates.  We designated the April 2016 and October 2016 interest 
rate swap agreements as fair value hedges of the risk of changes in the value of fixed-rate debt due to changes in interest rates 
for a portion of our fixed-rate borrowings.  In August 2019, we terminated the April 2016 and October 2016 interest rate swaps 
which resulted in a loss of $2.3 million that will be deferred as an offset to the carrying value of the related debt and will be 
recognized to interest expense through October 2025.  As of December 31, 2019, $2.2 million of this loss was included in long-
term debt in the consolidated balance sheet.  For the years ended December 31, 2019 and 2018, $2.6 million and $2.1 million, 
respectively, of expense and for the year ended December 31, 2017, $2.9 million of income was recorded to interest expense on 
the accompanying consolidated statements of operations related to these swap agreements.

By using derivative instruments, we are exposed to credit and market risk.  If a counterparty fails to fulfill its 
performance obligations under a derivative contract, our credit risk will equal the fair value gain in a derivative.  Generally, 
when the fair value of a derivative contract is positive, this indicates that the counterparty owes us, thus creating a repayment 
risk for us.  When the fair value of a derivative contract is negative, we owe the counterparty and, therefore, assume no 
repayment risk.  We minimize the credit (or repayment) risk in derivative instruments by entering into transactions with high-
quality counterparties.  We monitor our positions and the credit ratings of our counterparties, and we do not anticipate non-
performance by the counterparties.

Based on the agreements with our various counterparties, cash collateral is required to be provided when the net fair 

value of the derivatives, with the counterparty, exceeds a specific threshold.  If the threshold is exceeded, cash is either 
provided by the counterparty to us if the value of the derivatives is our asset, or cash is provided by us to the counterparty if the 
value of the derivatives is our liability.  As of December 31, 2019 and 2018, this threshold was not exceeded.  In all instances 
where we are party to a master netting agreement, we offset the receivable or payable recognized upon payment of cash 
collateral against the fair value amounts recognized for derivative instruments that have also been offset under such master 
netting agreements.

NOTE 26.  FAIR VALUE MEASUREMENTS

Assets and liabilities recorded at fair value in the consolidated balance sheets are categorized based upon the level of 

judgment associated with the inputs used to measure their fair value.  Hierarchical levels are directly related to the amount of 
subjectivity associated with the inputs to fair valuation of these assets and liabilities.  We are required to separately disclose 
assets and liabilities measured at fair value on a recurring basis, from those measured at fair value on a nonrecurring 
basis.  Nonfinancial assets measured at fair value on a nonrecurring basis are intangible assets and goodwill, which are 
reviewed for impairment annually in the fourth quarter and/or when circumstances or other events indicate that impairment 
may have occurred.  Determining which hierarchical level an asset or liability falls within requires significant judgment.  The 
following table summarizes the assets and liabilities measured at fair value in the consolidated balance sheets:

Interest Rate Swaps

Interest rate swap financial instruments were valued using the “income approach” valuation technique.  This method 
used valuation techniques to convert future amounts to a single present amount.  The measurement was based on the value 
indicated by current market expectations about those future amounts.  We use interest rate swaps as a means of managing 
interest expense and floating interest rate exposure to optimal levels.

Commodity Contracts

Commodity contract financial instruments were valued primarily based on prices and other relevant information 
observable in market transactions involving identical or comparable assets or liabilities including both forward and spot prices 
for commodities.  We use commodity derivative contracts for certain raw materials and energy costs such as copper, zinc, lead, 
ethane, electricity and natural gas to provide a measure of stability in managing our exposure to price fluctuations.

Foreign Currency Contracts

Foreign currency contract financial instruments were valued primarily based on relevant information observable in 

market transactions involving identical or comparable assets or liabilities including both forward and spot prices for 
currencies.  We enter into forward sales and purchase contracts to manage currency risk resulting from purchase and sale 
commitments denominated in foreign currencies.

The carrying values of cash and cash equivalents, accounts receivable and accounts payable approximated fair values 
due to the short-term maturities of these instruments.  The fair value of our long-term debt was determined based on current

Item 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND FINANCIAL 

DISCLOSURE

Not applicable.

Item 9A.  CONTROLS AND PROCEDURES

Our chief executive officer and our chief financial officer evaluated the effectiveness of our disclosure controls and 
procedures as of December 31, 2019.  Based on that evaluation, our chief executive officer and chief financial officer have 
concluded that, as of such date, our disclosure controls and procedures were effective to ensure that information Olin is 
required to disclose in the reports that it files or submits with the SEC under the Securities Exchange Act of 1934 is recorded, 
processed, summarized and reported within the time periods specified in the Commission’s rules and forms, and to ensure that 
information we are required to disclose in such reports is accumulated and communicated to our management, including our 
chief executive officer and chief financial officer, as appropriate to allow timely decisions regarding required disclosure.

In 2017, we began a multi-year implementation of new enterprise resource planning, manufacturing, and engineering 

systems. The project includes the required information technology infrastructure (collectively, the Information Technology 
Project).  Implementing the Information Technology Project involves significant changes in business processes and extensive 
organizational training.  During the second and third quarters of 2019, we implemented portions of the Information Technology 
Project to support and integrate significant processes, some of which relate to internal control over financial reporting and 
disclosure controls and procedures.  We believe we have taken and will continue to take the necessary steps to implement, 
monitor and maintain appropriate internal controls during the Information Technology Project transition period.  In connection 
with the Information Technology Project, we expect there will be a significant redesign of our business processes, some of 
which relate to internal control over financial reporting and disclosure controls.  Other than the aforementioned Information 
Technology Project, there have been no changes in our internal control over financial reporting that occurred during the quarter 
ended December 31, 2019, that have materially affected, or are reasonably likely to materially affect, our internal control over 
financial reporting.

Management’s report on internal control over financial reporting and the related report of Olin’s independent registered 

public accounting firm, KPMG LLP, are included in Item 8—“Consolidated Financial Statements and Supplementary Data.”

DESCRIPTION OF SECURITIES

DESCRIPTION OF COMMON STOCK

Exhibit 4(a)

The following summary description of our common stock is not complete and is qualified in its entirety by reference to the 
detailed provisions of our Amended and Restated Articles of Incorporation, as further amended or restated, which we refer to 
in this exhibit as the Articles of Incorporation, our bylaws, as amended, which we refer to in this exhibit as the Bylaws, and 
applicable provisions of the laws of Virginia, our state of incorporation, including without limitation the Virginia Stock 
Corporation Act (VSCA).  These statements do not purport to be complete, or to give full effect to the terms of the provisions of 
statutory or common law, and are subject to, and are qualified in their entirety by reference to, the terms of the Articles of 
Incorporation and the Bylaws, each of which has been filed as an exhibit to (or incorporated by reference in) our Annual 
Report on Form 10-K filed with the Securities and Exchange Commission, and to applicable provisions of Virginia law.

General

Under the Articles of Incorporation, our authorized capital stock consists of 240,000,000 shares of common stock, par 

value $1.00 per share, and 10,000,000 shares of preferred stock, par value $1.00 per share, issuable in one or more series.  
While at present we have only shares of common stock issued and outstanding, our Board of Directors is authorized by the 
Articles of Incorporation to provide in the future for issuance of the authorized preferred stock in one or more series, with such 
voting powers and with such designations, preferences and relative, participating, optional or other special rights, and 
qualifications, limitations or restrictions thereof, as shall be established by our board of directors or by a duly authorized 
committee thereof at such time.

The common stock is listed on The New York Stock Exchange under the trading symbol “OLN.”  All outstanding shares 
of our common stock are validly issued, fully paid and nonassessable.  The transfer agent and registrar for our common stock is 
EQ by Equiniti Shareowner Services.

Voting Rights and Election of Directors

Except as might otherwise be provided in any resolutions of the Board of Directors establishing the terms of a future 
series of preferred stock, holders of our common stock have the exclusive right to elect directors and are entitled to one vote per 
share on all matters submitted for action by the shareholders.  Shares representing a majority of the votes entitled to be cast on 
any matter, represented in person or by proxy at any meeting of shareholders, constitute a quorum for the transaction of 
business with respect to such matter.

Holders of common stock may not cumulate votes for the election of directors.  Under our Articles of Incorporation and 
Bylaws, the Board of Directors is divided into three classes, being as nearly equal in number as possible, with the directors in 
each class being elected to serve for a three-year term and until his or her successor shall have been duly elected or until such 
director’s death, resignation or removal.  

Our Bylaws provide that in an uncontested election of directors (that is, an election where the number of director 
nominees does not exceed the number of directors to be elected), each director nominee must receive the affirmative vote of a 
majority of the votes cast with respect to his or her election in order to be elected, meaning that the number of shares voted 
“for” a director must exceed the number of shares voted “against” that director.  The Bylaws provide that in any election of 
directors where there are more nominees for election than the number of directors to be elected, one or more of whom are 
properly proposed by shareholders, director nominees shall be elected by a plurality of the votes cast.

Our Bylaws provide that any director may be removed at any time but only with cause, by the affirmative vote of the 

holders of a majority of the outstanding shares entitled to vote in the election of directors, taken at a special meeting the 
purpose of which (or one of the purposes, as stated in the meeting notice) is removal of the director.  Any vacancy on our Board 
caused by a director’s death, resignation, disqualification or removal, or an increase in the number of directors, or for any other 
reason, may be filled (a) by vote of the shareholders, but only at an annual meeting of shareholders, or (b) by the affirmative 
vote of a majority of the remaining directors, regardless of the presence of a quorum, at an regular or special meeting of the 
Board.  A director so elected by the Board shall hold office only until the next annual election of directors, while a director so 
elected by shareholders shall hold office until the term of the class to which he or she has been elected expires, and in each case 
until his or her successor shall have been duly elected or until such director’s death, resignation or removal.

Dividend and Liquidation Rights

Holders of our common stock are entitled to dividends as declared by our board of directors from time to time in the 

manner and upon the terms and conditions provided in Virginia law and in the Articles of Incorporation, after payment of, or 
provision for, full cumulative dividends on and any required redemptions of shares of any preferred stock then outstanding.  

In the event of the liquidation, dissolution or winding up of our business, holders of common stock are entitled to receive 

pro rata all our remaining assets available for distribution, after satisfaction of the prior preferential rights of any then-
outstanding preferred stock and the satisfaction of all our debts and liabilities.

Other Rights

Holders of our common stock have no preemptive or subscription rights and have no liability for further calls or 

assessments.  Our common stock is not convertible or exchangeable into any other securities and is not subject to any 
redemption or sinking fund provisions.

Advance Notice for Shareholder Proposals and Nominations

Our Bylaws contain provisions requiring advance notice be delivered to the Company of any business to be brought by a 

shareholder before an annual meeting and providing for procedures to be followed by shareholders in nominating persons for 
election to our Board of Directors.  For business to be brought by a shareholder before an annual meeting, or for shareholder 
nominations for election to the Board of Directors, a shareholder must give notice no later than 90 days prior to the anniversary 
of the date of the preceding year’s annual meeting.  In each case, the notice must contain the information required by our 
Bylaws, and the shareholder(s) and nominee(s) must comply with the information and other requirements required by our 
Bylaws.

Special Meetings of Shareholders

Our Bylaws provide that special meetings of shareholders, for any purpose or purposes, unless otherwise provided by 
law or the Articles of Incorporation, may be called by the Chairman of the Board of Directors, the President or the Board of 
Directors, or by the holders of a majority of the shares of the issued and outstanding stock entitled to vote at the meeting.

Anti-Takeover Provisions

Various provisions of the VSCA, as well as the provisions of our Articles of Incorporation and Bylaws governing the 

election of directors, could have the effect of delaying or discouraging some transactions involving an actual or potential 
change in control of our company or its management.  However, Article VIII, Section 6 of our Bylaws provides that Article 
14.1 - Control Share Acquisitions of the VSCA (which, in general, would limit the voting rights of holders engaging in certain 
acquisitions of our shares in excess of certain thresholds specified in that statute, absent the approval of our shareholders) shall 
not apply to acquisitions of our shares. 

Amendments of Articles of Incorporation and Bylaws

In general, any amendment or restatement of the Articles of Incorporation is subject to approval by a majority of the 

votes entitled to be cast by each voting group of our stockholders entitled to vote thereon, unless the Board of Directors shall 
require a greater vote.  Our Bylaws provide that they may be altered, amended or repealed, and new Bylaws adopted, by action 
of the Board (except as otherwise limited in the Bylaws) or by vote of our shareholders at an annual or special meeting where 
notice of such amendment has been duly given.

beginning of such Stock Grant Period; provided, however, that (i) in the event a person becomes in a Stock Grant Period a Non-
employee Director subsequent to such Retainer Credit Date but prior to May 1, such person shall receive the full annual cash 
retainer on the next Credit Date; or (ii) in the event a person becomes a Non-employee Director subsequent to May 1, such Non-
employee Director, on the Credit Date next following his or her becoming such, shall receive a cash retainer equal to one-twelfth

increase in the percentage of stock owned by any person or Group as a result of a transaction in which Olin acquires its 
stock in exchange for property, provided that the acquisition of additional stock by any person or Group deemed to own 
more than 50% of the total fair market value or total voting power of Olin’s stock on January 1, 2005, shall not constitute 
a Change in Control); or

(b) 

any person or Group acquires (or has acquired during the 12-month period ending on the date of the 
most recent acquisition by such person or Group) ownership of Olin stock possessing 30% or more of the total voting 
power of Olin stock; or

directors whose appointment or election is not endorsed by a majority of the members of Olin’s board of directors prior 
to the date of the appointment or election; or

(d) 

any person or Group acquires (or has acquired during the 12-month period ending on the date of the 
most recent acquisition by such person or Group) assets from Olin that have a total Gross Fair Market Value equal to 
40% or more of the total Gross Fair Market Value of all Olin assets immediately prior to such acquisition or acquisitions, 
provided that there is no Change in Control when Olin’s assets are transferred to:

majority-owned subsidiary of Olin after the transaction, is not a Change in Control.

Grants and Deferrals.

(a)  Annual Stock Grant.  Subject to the terms and conditions of the Plan, on the Retainer Credit Date each 
year, each Non-employee Director shall be credited with a number of shares of Common Stock with an aggregate Fair 
Market Value on such Retainer Credit Date equal to $115,000, rounded to the nearest 100 shares.  To be entitled to such 
credit  for  any  Stock  Grant  Period,  a  Non-employee  Director  must  be  serving  as  such  on  the  Retainer  Credit  Date 
immediately prior to the beginning of such Stock Grant Period; provided, however, that (i) in the event a person becomes 
a Non-employee Director subsequent to the Retainer Credit Date but prior to May 1, such Non-employee Director shall 
receive the full Annual Stock Grant on the next Credit Date; or (ii) in the event a person becomes a Non-employee Director 
subsequent to May 1, such Non-employee Director, on the Credit Date next following his or her becoming such, shall 
be credited with that number of shares of Common Stock equal to one-twelfth of the number of shares issued to each 
other Non-employee Director as the Annual Stock Grant for such Stock Grant Period, multiplied by the number of whole 
calendar months remaining in such Stock Grant Period following the date he or she becomes a Non-employee Director 
(rounded up to the next whole share in the event of a fractional share).  Actual receipt of shares shall be deferred and 
each eligible Non-employee Director shall receive a credit to his or her Stock Account for such shares on the date of such 
credit.  A Non-employee Director may elect in accordance with Section 6(e) to defer to his or her Stock Account receipt 
of all or any portion of such shares after such Non-employee Director’s Retirement Date.  Except with respect to any 
shares the director has so elected to defer, certificates representing such shares shall be delivered to the Non-employee 
Director (or in the event of death, to his or her beneficiary designated pursuant to Section 6(h)) on or as soon as practicable, 
but no later than thirty (30) days, following such Non-employee Director’s Retirement Date.

(b) 

Annual Retainer Stock Grant.  Subject to the terms and conditions of the Plan, each Non-employee 
Director who is such on the Retainer Credit Date of that year shall receive that number of shares (rounded up to the next 
whole share) of Common Stock having an aggregate Fair Market Value of $40,000 on such Retainer Credit Date.  To be 
entitled to such credit for any Stock Grant Period, a Non-employee Director must be serving as such on the Retainer 
Credit Date immediately prior to the beginning of such Stock Grant Period; provided, however, that (i) in the event a 
person becomes in a Stock Grant Period a Non-employee Director subsequent to such Retainer Credit Date but prior to 
May 1, such person shall receive the full Annual Retainer Stock Grant on the next Credit Date; or (ii) in the event a person 
becomes a Non-employee Director subsequent to May 1, such Non-employee Director, on the Credit Date next following 
his or her becoming such, shall receive that number of shares of Common Stock equal to one-twelfth of the number of 
shares issued to each other Non-employee Director as the Annual Retainer Stock Grant for such Stock Grant Period, 
multiplied by the number of whole calendar months remaining in such Stock Grant Period following the date he or she 
becomes a Non-employee Director (rounded up to the next whole share in the event of a fractional share).  A Non-
employee Director may elect to defer receipt of all or any portion of such shares in accordance with Section 6(e).  Except 
with respect to any shares the director has so elected to defer, certificates representing such shares shall be delivered to 
such Non-employee Director (or in the event of death, to his or her beneficiary designated pursuant to Section 6(h)) as 
soon as practicable, but no later than thirty (30) days, following the Retainer Credit Date (or the applicable Credit Date 
in the event a person becomes a Non-employee Director subsequent to the Retainer Credit Date).

Payment of Chairman of the Board Fees, Lead Director Fees, Committee Chair Fees and Cash Retainer 
and Election to Receive Fees in Stock in Lieu of Cash.  Cash payments of Committee Chair fees shall be made on the

in four equal payments on the first four Credit Dates of each year.  The Cash Retainer payable to the Non-employee 
Director shall be payable on the Retainer Credit Date of each year (or, in the event a person becomes a Non-employee 
Director  subsequent  to  the  Retainer  Credit  Date,  the  next  applicable  Credit  Date).    Except  with  respect  to  any  cash 
payments the director has elected to defer in accordance with Section 6(e), such payment shall be delivered to the Non-
employee Director on or as soon as practicable, but no later than thirty (30) days, following the applicable Credit Date 
(or, in the case of the Cash Retainer, the Retainer Credit Date or applicable Credit Date).  Subject to the terms and 
conditions of the Plan, a Non-employee Director may elect to receive all or a portion of the fees as Chairman of the Board, 
fees as Lead Director, fees as a Committee Chair and the Cash Retainer payable in cash by the Company for his or her 
service as a director for the calendar year in the form of shares of Common Stock.  Such election shall be made in 
accordance with Section 6(e).  A Non-employee Director who so elects to receive all or a portion of the Cash Retainer 
in the form of shares for such year shall be paid on the Retainer Credit Date (or the applicable Credit Date).   The number 
of shares (rounded up to the next whole share in the event of a fractional share) payable to a Non-employee Director who 
so elects to receive all or a portion of the Cash Retainer in the form of shares shall be equal to such cash amount divided 
by the Fair Market Value of a share of Common Stock on the Retainer Credit Date (or the applicable Credit Date) of such 
year.  Except with respect to any shares the director has elected to defer in accordance with Section 6(e), certificates 
representing such shares shall be delivered to the Non-employee Director on or as soon as practicable, but no later than 
thirty (30) days, following the Retainer Credit Date (or the applicable Credit Date).  A Non-employee Director who so 
elects to receive all or a portion of other fees in the form of shares for such year shall be paid on the applicable Retainer 
Credit Date or Credit Date on which the other fees, would have been paid.  The number of shares (rounded up to the next 
whole share in the event of a fractional share) payable to a Non-employee Director who so elects to receive all or a portion 
of the Board Chairman fees, Lead Director fees or Committee Chair fees in the form of shares shall be equal to such cash 
amount divided by the Fair Market Value of a share of Common Stock on the relevant Credit Date.  Except with respect 
to any shares the director has elected to defer in accordance with Section 6(e), certificates representing such shares shall 
be delivered to the Non-employee Director on or as soon as practicable, but no later than thirty (30) days, following the 
applicable Credit Date.

(d)  Deferral of Chairman of the Board Fees, Lead Director Fees, Committee Chair Fees and Cash Retainer.  
Subject to the terms and conditions of the Plan, a Non-employee Director may elect to defer all or a portion of the shares 
payable under Section 6(c) and all or a portion of the fees as Chairman of the Board, fees as Lead Director, fees as a 
Committee Chair and Cash Retainer payable in cash by the Company for his or her service as a director for the calendar 
year.  Such election shall be made in accordance with Section 6(e).  A Non-employee Director who elects to so defer 
shall have any deferred shares deferred in the form of shares of Common Stock and any deferred cash fees and retainer 
deferred in the form of cash.

(e) 

Elections.

(1)  Deferrals.  Effective as of January 1, 2005, all elections to defer payment of compensation 

under this Plan shall:

• 

• 

• 

be made in writing and delivered to the Secretary of the Company,

be irrevocable once the year to which the election relates commences,

be made before January 1 of the year in which the shares of Common Stock or 
director’s fees and retainer are to be earned (or, in the case of an individual who 
becomes a Non-employee Director during a calendar year, within 30 days of the 
date of his or her election as a director; notwithstanding the foregoing no amounts 
earned prior to an election shall be deferred by new participants), and

• 

specify the portions (in 25% increments) to be deferred.

(2)  Stock and Cash Account Payments.  Effective as of January 1, 2005, Stock and Cash Accounts 
shall be paid in a single lump sum payment within 30 days of the Non-employee Director’s Retirement Date 
unless the Non-employee Director makes an election as set forth below:

• 

a payment election, if any, shall be made on or before the earlier of:

the time such individual makes any deferral election under the Plan, or

the end of the 30 day period following the date an individual first becomes 
a Non-employee Director.

• 

• 

a payment election may specify a payment date, provided such date is after the Non-
employee Director’s Retirement Date.

a  payment  election  may  specify  the  method  of  payment  (lump  sum  or  annual 
installments (up to 10)).

Notwithstanding any election, Plan payments will be made (or annual installments will begin) upon a Non-employee Director’s 
death.  All payments shall be made (or each annual installment shall be paid) within 30 days of the prescribed payment date, and 
any payment election shall be irrevocable except as permitted in Section 6(e)(4) below.

(3)  Dividends and Interest on Stock and Cash Accounts.  Dividends and interest on Stock and 
Cash Accounts  shall  be  paid  as  provided  in  Section  6(e)(8)  unless  the  Non-employee  Director  makes  an

accordance with Sections 6(e)(2) and (4) herein), provided that such election is made within the time prescribed 
by Section 6(e)(2) above.

(4)  Change in Payment Election.  Any change with respect to a Non-employee Director’s payment 
election under the Plan will not be effective for one year, must be made at least one (1) year in advance of the 
first date payment is scheduled and must further defer all payments by at least five (5) years from the prior 
scheduled payment date.  Notwithstanding the foregoing, for the transition period beginning January 1, 2005 
and ending December 31, 2008, any Non-employee Director may make a payment election in accordance 
with Code Section 409A (and applicable IRS transition relief), in the time and manner prescribed by the 
Committee and subject to the following provisions.  As of December 31, 2008, any then effective transition 
payment elections shall be irrevocable for the duration of a Non-employee Director’s participation in the Plan 
except as set forth in the first sentence of this Section 6(e)(4).  No election made in 2008 under this transition 
relief will apply to amounts that would otherwise be payable in 2008, nor may such election cause an amount 
to be paid in 2008 that would not otherwise be payable in 2008.  No election under this transition relief may 
be made retroactively, when Plan payments are imminent, or after a Non-employee Director has left the Board.

(5)  Stock Account.  A Non-employee Director who has elected to defer shares under Sections 
6(b) or 6(d) shall receive a credit to his or her Stock Account (a) on the Retainer Credit Date for amounts 
deferred from the Annual Stock Retainer Grant or the Cash Retainer (or the applicable Credit Date in the event 
a person becomes a Non-employee Director subsequent to the Retainer Credit Date), and (b) on the applicable 
Credit Date for deferrals of other fees.  The amount of such credit shall be the number of shares so deferred 
(rounded to the next whole share in the event of a fractional share).  A Non-employee Director may elect to 
defer the cash dividends paid on his or her Stock Account in accordance with Section 6(e)(3).

(6)  Cash Account.  On the applicable Credit Date or in the case of the Cash Retainer, on the 
Retainer Credit Date (or applicable Credit Date), a Non-employee Director who has elected to defer cash fees 
and/or the Cash Retainer under Section 6(d) in the form of cash shall receive a credit to his or her Cash Account.  
The amount of the credit shall be the dollar amount of such Director’s Board Chairman fees, Lead Director 
fees or Committee Chair fees earned during the immediately preceding quarterly period or the amount of the 
Cash Retainer to be paid for the calendar year, as the case may be, and in each case, specified for deferral in 
cash.  A Non-employee Director may elect to defer interest paid on his or her Cash Account in accordance 
with Section 6(e)(3).

(7) 

Installment Payments.  Installment payments from an Account shall be equal to the Account 
balance (expressed in shares in the case of the Stock Account, otherwise the cash value of the Account) at the 
time of the installment payment times a fraction, the numerator of which is one and the denominator of which 
is the number of installments not yet paid.  Fractional shares to be paid in any installment shall be rounded 
up to the next whole share.  In the event of an election under Section 6(c) for Board Chairman fees, Lead 
Director fees, Committee Chair fees or Cash Retainer to be paid in shares of Common Stock, the election 
shall specify the portion (in 25% increments) to be so paid.

 
 
(8)  Dividends and Interest.  Each time a cash dividend is paid on Common Stock, a Non-employee 
Director who has shares of such stock credited to his or her Stock Account shall be paid on the dividend 
payment date such cash dividend in an amount equal to the product of the number of shares credited to the 
Non-employee Director’s Stock Account on the record date for such dividend times the dividend paid per 
applicable share unless the director has elected to defer such dividend to his or her Stock Account as provided 
herein.  If the Non-employee Director has elected to defer such dividend, he or she shall receive a credit for 
such dividends on the dividend payment date to his or her Stock Account.  The amount of the dividend credit 
shall be the number of shares (rounded to the nearest one-thousandth of a share) determined by multiplying 
the dividend amount per share by the number of shares credited to such director’s Stock Account as of the 
record date for the dividend and dividing the product by the Fair Market Value per share of Common Stock 
on the dividend payment date.  A Non-employee Director who has a Cash Account shall be paid interest 
directly on such account’s balance at the end of each calendar quarter, payable at a rate equal to the Interest 
Rate in effect for such quarter unless such Non-employee Director has elected to defer such interest to his or 
her Cash Account, in which case such interest shall be credited to such Cash Account at the end of each 
calendar quarter.  All amounts paid pursuant to this subsection (8) shall be paid on or as soon as practicable, 
but no later than thirty (30) days, following the applicable payment date (i.e., the applicable dividend payment 
date or end date of the fiscal quarter).

(9)  Payouts.  Cash Accounts will be paid out in cash and Stock Accounts shall be paid out in 
shares of Common Stock unless the Non-employee Director elects at the time the payment is due to take the 
Stock Account in cash. 

(f) 

No Stock Rights.  Except as expressly provided herein, the deferral of shares of Common Stock into 
a Stock Account shall confer no rights upon such Non-employee Director, as a shareholder of the Company or otherwise, 
with respect to the shares held in such Stock Account, but shall confer only the right to receive such shares credited as 
and when provided herein.

(g) 

Change in Control.  Notwithstanding anything to the contrary in this Plan or any election, in the event 
a Change in Control occurs, amounts and shares credited to Cash Accounts (including interest accrued to the date of 
payout)  and  Stock Accounts  shall  be  promptly  (but  no  later  than  thirty  (30)  days  following  the  Change  in  Control) 
distributed to Non-employee Directors except the Stock Account shall be paid out in cash and not in the form of shares 
of Common Stock.  For this purpose, the cash value of the amount in the Stock Account shall be determined by multiplying 
the number of shares held in the Stock Account by the higher of (i) the highest Fair Market Value of Common Stock on 
any date within the period commencing thirty (30) days prior to such Change in Control and ending on the date of the 
Change in Control, or (ii) if the Change in Control occurs as a result of a tender or exchange offer or consummation of 
a corporate transaction, then the highest price paid per share of Common Stock pursuant thereto.

(h) 

Beneficiaries.  A Non-employee Director may designate at any time and from time to time a beneficiary 
for his or her Stock and Cash Accounts in the event his or her Stock or Cash Account may be paid out following his or 
her death.  Such designation shall be in writing and must be received by the Company prior to the death to be effective.

(i) 

Prior Plan Accounts.  Any transfers made to a Cash Account or a Stock Account from Prior Plans shall 
be maintained and administered pursuant to the terms and conditions of this Plan; provided that prior annual 100- or 204-
share grant deferrals shall be treated as deferrals of 204-share grants under this Plan, the $25,000 annual share grant under 
the 1994 Plan shall be treated as deferrals under Paragraph 6(b) hereof and deferrals of meeting fees under all Prior Plans 
and of the excess retainer under the 1994 Plan shall be treated as deferrals under Paragraph 6(c) hereof.  Prior elections 
and beneficiary designations under the 1994 Plan and this Plan shall govern this Plan unless changed subsequent to 
October 2, 1997.

7. 

Limitations and Conditions.

(a) 

Total Number of Shares.  The total number of shares of Common Stock that may be issued to Non-

employee Directors under the Plan is 850,000, which may be increased or decreased by the events set forth in Section 8.  
Such total number of shares may consist, in whole or in part, of authorized but unissued shares.  If any shares granted 
under this Plan are not delivered to a Non-employee Director or a beneficiary because the payout of the grant is settled 
in cash, such shares shall not be deemed to have been delivered for purposes of determining the maximum number of 
shares available for delivery under the Plan.  No fractional shares shall be issued hereunder.  In the event a Non-employee 
Director is entitled to a fractional share, such share amount shall be rounded upward to the next whole share amount.

(b)  No Additional Rights.  Nothing contained herein shall be deemed to create a right in any Non-employee 
Director to remain a member of the Board, to be nominated for reelection or to be reelected as such or, after ceasing to 
be such a member, to receive any cash or shares of Common Stock under the Plan which are not already credited to his 
or her accounts.

8. 

Stock Adjustments.  In the event of any merger, consolidation, stock or other non-cash dividend, extraordinary 
cash dividend, split-up, spin-off, combination or exchange of shares or recapitalization or change in capitalization, or any other 
similar corporate event, the Committee shall make such adjustments in (i) the aggregate number of shares of Common Stock that 
may be issued under the Plan as set forth in Section 7(a) and the number of shares that may be issued to a Non-employee Director 
with respect to any year as set forth in Section 6(a) and the number of shares of Common Stock held in a Stock Account, (ii) the 
class of shares that may be issued under the Plan, and (iii) the amount and type of payment that may be made in respect of unpaid 
dividends on shares of Common Stock whose receipt has been deferred pursuant to Section 6(e), as the Committee shall deem 
appropriate in the circumstances.  The determination by the Committee as to the terms of any of the foregoing adjustments shall 
be final, conclusive and binding for all purposes of the Plan.

9. 

Amendment and Termination.  This Plan may be amended, suspended or terminated by action of the Board, 
except to the extent that amendments are required to be approved by the Company’s shareholders under applicable law or the rules 
of the New York Stock Exchange or any other exchange or market system on which the Common Stock is listed or traded.  No 
termination of the Plan shall adversely affect the rights of any Non-employee Director with respect to any amounts otherwise 
payable or credited to his or her Cash Account or Stock Account.

10. 

Nonassignability.  No right to receive any payments under the Plan or any amounts credited to a Non-employee 
Director’s Cash or Stock Account shall be assignable or transferable by such Non-employee Director other than by will or the 
laws of descent and distribution or pursuant to a domestic relations order.  The designation of a beneficiary under Section 6(h) by 
a Non-employee Director does not constitute a transfer.

11. 

Unsecured Obligation.  Benefits payable under this Plan shall be an unsecured obligation of the Company.

12. 

Rule 16b-3 Compliance.  It is the intention of the Company that all transactions under the Plan be exempt from 
liability imposed by Section 16(b) of the Exchange Act.  Therefore, if any transaction under the Plan is found not to be in compliance 
with an exemption from such Section 16(b), the provision of the Plan governing such transaction shall be deemed amended so 
that the transaction does so comply and is so exempt, to the extent permitted by law and deemed advisable by the Committee, and 
in all events the Plan shall be construed in favor of its meeting the requirements of an exemption.  Scheduled Plan payments will 
be delayed where the Committee reasonably anticipates that the making of the payment will violate Federal securities laws or 
other applicable law; provided that such payment shall be made at the earliest date at which the Committee reasonably anticipates 
that the making of the payment will not cause such violation.

13. 

Code Section 409A Compliance.  To the extent any provision of the Plan or action by the Board or Committee 
would subject any Non-employee Director to liability for interest or additional taxes under Code Section 409A, it will be deemed 
null and void, to the extent permitted by law and deemed advisable by the Committee.  It is intended that the Plan will comply 
with Code Section 409A, and the Plan shall be interpreted and construed on a basis consistent with such intent.  The Plan may be 
amended in any respect deemed necessary (including retroactively) by the Committee in order to preserve compliance with Code 
Section 409A.  If, regardless of the foregoing, any Non-employee Director is liable for interest or additional taxes under Code 
Section 409A with respect to his or her Account (or a portion thereof), such Account (or applicable portion thereof) shall be paid 
at such time.  The preceding shall not be construed as a guarantee of any particular tax effect for any benefits or amounts deferred 
or paid out under the Plan.

3. 

Performance Share Awards

a. 

One-half (1/2) of the total target Performance Share Award shall be designated in TSR Performance 
Shares, and the remaining one-half in Net Income Performance Shares.

b. 

The number of target TSR Performance Shares for each Participant shall be adjusted based upon a 
comparison of Olin’s TSR during the Performance Cycle with the TSR of the Performance Share 
Comparison Group over the same period, in accordance with the following chart:

If Olin’s TSR for a Performance Cycle is:
At or above the 80th Percentile of the Performance Share

of the TSR for the Performance Share Comparison

100%

d. 

The Company shall use linear interpolation to determine the number of additional Net Income 
Performance Shares for performance between 60% and 100% and for 100% and 140% of the Net Income 
Goal.  For example, if the Net Income Goal for a three-year Performance Cycle is $300 million, and a 
Participant’s target number of Net Income Performance Shares is 10,000, the Participant would receive 
the number of Net Income Performance Shares set forth below opposite the relevant Net Income for that 
Performance Cycle:

e. 

As soon as practicable in the calendar year following the end of the Performance Cycle, the Company 
shall calculate the number of Performance Shares that vested (the “Final Share Number”) for all 

Participants whose Performance Share Awards have vested during or at the end of such Performance 
Cycle.

4. 

Vesting and Forfeiture

a. 

b. 

c. 

d. 

e. 

Except as otherwise provided by the Committee, the LTIP, this Program or the Performance Share Award 
certificate, an interest in a Performance Share Award shall vest only if the Participant is an employee of 
the Company or a subsidiary on the last day of the relevant Performance Cycle.

If a Participant’s employment with the Company or a subsidiary terminates for cause or without the 
Company’s consent (other than as the result of the Participant’s death, disability or retirement) before a 
Performance Share Award has vested, his or her Performance Share Award shall terminate and all rights 
under such Award shall be forfeited.

If a Participant’s employment with the Company or a subsidiary terminates as the result of his or her 
disability, (as that term is defined in Section 409A of the Code or any successor provision), or retirement 
under any of the Company’s retirement plans before a Performance Share Award has vested, the 
Participant shall be entitled to a pro rata Performance Share Award, payable solely in cash at the time that 
the Performance Share Award would otherwise be payable under Section 5.  The cash payment shall be 
equal to the Final Share Number calculated in accordance with Sections 3 and 5 of this Program, 
multiplied by the Fair Market Value on the last day of the relevant Performance Cycle, multiplied by a 
fraction with a numerator equal to the number of months during the Performance Cycle the Participant 
was employed by the Company or a subsidiary (rounded up to the nearest whole month) and a 
denominator of 36.

If a Participant’s employment with the Company or a subsidiary terminates as the result of his or her 
death before a Performance Share Award has vested, the Participant shall be entitled to a pro rata 
Performance Share Award, payable solely in cash within ninety (90) days of the Participant’s death.  The 
cash payment shall be equal to the Participant’s target number of Performance Shares, as the case may 
be, multiplied by the Fair Market Value on the date of the Participant’s death (or the next trading day, if 
the Common Stock was not traded on such date), multiplied by a fraction with a numerator equal to the 
number of months during the Performance Cycle the Participant was employed by the Company or a 
subsidiary (rounded up to the nearest whole month) and a denominator of 36.

If a Participant’s employment with the Company or a subsidiary terminates for any other reason, the 
Company shall determine the portion, if any, of the Performance Share Award that shall not be forfeited, 
and the form of payment (cash or shares or a combination) that the Participant shall receive.  That 
determination shall be made by the Committee in the case of any officer, and by the Chairman of the 
Board, President, Chief Executive Officer, or any Vice President, in the case of any non-officer 
employee.  Notwithstanding this Section 4, payment shall be made pursuant to Section 5.

5. 

Payment and Timing

a. 

b. 

c. 

As soon as is administratively practicable after the determination of the Final Share Number, but not later 
than the last day of the calendar year following the Performance Cycle, the Company will (i) issue to each 
Participant a number of shares of the Common Stock equal to one-half of the Final Share Number, rounded 
down to the nearest whole share if such number is not a whole number, and (ii) pay the Participant in cash an 
amount equal to the Fair Market Value of one-half of the Final Share Number of shares of Common Stock on 
the last day of the Performance Cycle, rounded up to the nearest whole share if such number is not a whole 
number.

No dividends or dividend equivalents shall be paid on any Performance Shares.

In calculating the number of Performance Shares, all percentages and percentile numbers will be rounded to 
the nearest one-hundredth of a percent.

6. 

Miscellaneous

a. 

By acceptance of the Performance Share Award, each Participant agrees that such Award is special 
compensation, and that any amount paid will not affect:

i. 

ii. 

iii. 

the amount of any pension under any pension or retirement plan in which he or she participates as an 
employee of Olin,

the amount of coverage under any group life insurance plan in which he or she participates as an 
employee of Olin, or

the benefits under any other benefit plan of any kind heretofore or hereafter in effect, under which 
the availability or amount of benefits is related to compensation.

b. 

c. 

The Company will withhold from the distribution of any cash pursuant to Performance Share Awards the 
amount necessary to satisfy the Participant’s federal, state and local withholding tax requirements.  It is 
the Company’s intention that all income tax liability on Performance Share Awards be deferred in 
accordance with the applicable requirements of Code Section 409A, until the Participant actually 
receives such shares or payment thereof.

To the extent any provision of the Program (or any Performance Share Award) or action by the Board of 
Directors or Committee would subject any Participant to liability for interest or additional taxes under 
Code Section 409A, it will be deemed null and void, to the extent permitted by law and deemed 
advisable by the Committee.  It is intended that the Program (and any Performance Share Award) will 
comply with Code Section 409A, and the Program (and any Performance Share Award) shall be 
interpreted and construed on a basis consistent with such intent.  The Program (and any Performance 
Share Award) may be amended in any respect deemed necessary (including retroactively) by the 
Committee in order to preserve compliance with Code Section 409A.  The preceding shall not be 
construed as a guarantee of any particular tax effect for Program benefits or Performance Share Awards.  
Except as specifically provided in the LTIP, a Participant (or beneficiary) is solely responsible and liable 
for the satisfaction of all taxes and penalties that may be imposed on the Participant (or beneficiary) in 
connection with any distributions to such Participant (or beneficiary) under the Program (including any 
taxes and penalties under Code Section 409A), and neither Olin nor any Affiliate shall have any 
obligation to indemnify or otherwise hold a Participant (or beneficiary) harmless from any or all of such 
taxes or penalties.
