Item 1.Business

The Company

SPLP is a diversified global holding company that owns and operates businesses and has significant interests in leading companies in various industries, including diversified industrial products, energy, defense, supply chain management and logistics, banking and youth sports. SPLP operates through the following segments: Diversified Industrial, Energy, Financial Services, and Corporate and Other. Each of our companies has its own management team with significant experience in their industries. Our subsidiary, Steel Services Ltd ("Steel Services"), through management services agreements, provides services to us and some of our companies which include assignment of C-Level management personnel, legal, tax, accounting, treasury, consulting, auditing, administrative, compliance, environmental health and safety, human resources, marketing, investor relations, operating group management and other similar services. We work with our businesses to increase corporate value over the long term for all stakeholders by implementing our unique strategy discussed in more detail below.

SPLP is managed by SP General Services LLC ("Manager"), pursuant to the terms of an amended and restated management agreement ("Management Agreement") discussed in further detail in Note 20 – "Related Party Transactions" to the SPLP consolidated financial statements found elsewhere in this Form 10-K. From its founding in 1990, the Manager and its affiliates have focused on increasing value for investors in the entities it has managed. Our wholly-owned subsidiary, Steel Partners Holdings GP Inc. ("General Partner"), is our general partner. The General Partner has a board of directors ("Board of Directors"). The Board of Directors is currently comprised of eight members, six of whom are elected annually by our unitholders and two of whom are appointed by the Manager. Warren G. Lichtenstein, the Executive Chairman of our Manager, serves as the Executive Chairman of the Board of Directors.

Products and Product Mix

Diversified Industrial Segment

The Diversified Industrial segment is comprised of manufacturers of engineered niche industrial products, with leading market positions in many of the markets they serve. The businesses in this segment distribute products to customers through their sales personnel, outside sales representatives and distributors in North and South America, Europe, Australia, Asia and several other international markets. Below is additional information related to the businesses within the Diversified Industrial segment.

Joining Materials - TheJoining Materials business primarily fabricates precious metals and their alloys into brazing alloys. Brazing alloys are used to join similar and dissimilar metals, as well as specialty metals and some ceramics, with strong, hermetic joints. The Joining Materials business offers these metal joining products in a wide variety of alloys, including gold, silver, palladium, copper, nickel, aluminum and tin. These brazing alloys are fabricated into a variety of engineered forms and are used in many industries, including electrical, appliance, transportation, construction and general industrial, where dissimilar material and metal joining applications are required. Operating income from precious metal products is principally derived from the "value-added" of processing and fabricating and not from the direct purchase and resale of precious metals. The Joining Materials business enters into commodity futures and forward contracts to mitigate the impact of price fluctuations on its precious and certain non-precious

2

metal inventories that are not subject to fixed price contracts. We believe that our Joining Materials business is the North American market leader in many of the markets that it serves.

Tubing - The Tubing business manufactures a wide variety of stainless and low carbon steel tubing products. The Tubing business manufactures some of the world's longest continuous seamless stainless steel tubing coils, up to 6,000 feet, serving primarily the petrochemical and oil & gas infrastructure markets. In addition, it is a top supplier of precision, small diameter (less than 3 mm) coil tubing to industry leading specifications serving the aerospace, defense and health care markets. The Tubing business is also a leading manufacturer of mechanical and fluid-carrying welded low carbon tubing used for diverse industries, including the automotive, heavy truck, heating, cooling and oil & gas markets. Products are delivered in continuous lengths from 2 inches to 30,000 feet in coil, cut or spool packaging styles.

Building Materials - The Building Materials business manufactures and supplies products primarily to the commercial construction and building industries. It manufactures fasteners, adhesives and fastening systems for the U.S. commercial low-slope roofing industry, which are sold to building and roofing material wholesalers, roofing contractors and private label roofing system manufacturers, and a line of engineered specialty fasteners for the building products industry for fastening applications in the remodeling and construction of homes, decking and landscaping. We believe that our primary business unit in the Building Materials business is the market leader in fasteners and accessories for commercial low-slope roofing applications and that the majority of the net sales for our Building Materials business are for the commercial construction repair and replacement market.

Performance Materials - The Performance Materials business manufactures woven substrates of fiberglass, quartz, carbon and aramid materials for specialty applications in a wide expanse of markets requiring highly engineered components. Its products are used in a wide range of advanced composite applications, such as civilian and military aerospace components, printed electronic circuit boards, automotive and industrial components, and substrates for civilian and military armor applications.

Electrical Products - The Electrical Products business designs, manufactures and markets power electronics, motion control, power protection, power quality electromagnetic equipment, and custom ball-screws, gears and gearboxes used in a variety of medical, commercial and military aerospace, computer, datacom, industrial, specialty LED lighting, test & measurement, and telecom applications. Its products are generally incorporated into larger systems to improve operating performance, safety, reliability and efficiency.

Kasco Blades and Route Repair Services ("Kasco") - The Kasco business provides meat-room blade products, repair services and resale products for the meat and deli departments of supermarkets, restaurants, meat and fish processing plants, and for distributors of electrical saws and cutting equipment, principally in North America and Europe. The Kasco business also provides cutting blades for bakeries, in addition to wood cutting blade products for the pallet manufacturing, pallet recycler and portable saw mill industries in North America.

Packaging - The Packaging business manufactures and distributes foils, films and laminates used to enhance the visual appeal of products and packaging. Packaging's laminates and foils businesses produce carton board laminates and foils for the packaging of consumer goods, as well as the food and confectionery, tobacco, health and beauty, personal care, greeting cards, books, magazines, footwear, sports goods, and office and promotional products industries. The Packaging business includes the operations of Dunmore Corporation in the U.S. and Dunmore Europe GmbH in Germany (collectively, "Dunmore"), which were acquired in February 2018. Dunmore manufactures and distributes coated, laminated and metallized films for engineered applications in the imaging, aerospace, insulation and solar photo-voltaic markets and also provides products for custom and special applications.

Energy Segment

The Energy segment provides drilling and production services to the oil & gas industry and owns a youth sports business. Its parent company also has equity method and other investments in a number of businesses. Below is additional information related to the consolidated businesses within the Energy segment.

Steel Energy - The Energy business provides completion, re-completion and production services to exploration and production companies in the oil & gas business. The services provided include well completion and recompletion, well maintenance and workover, snubbing, flow testing, down hole pumping, plug and abandonment, well logging and perforating wireline services.

Steel Sports - Steel Sports is a social impact organization that strives to provide a first-class youth sports experience emphasizing positive experiences and instilling the core values of discipline, teamwork, safety, respect and integrity.

Financial Services Segment

3

The Financial Services segment consists primarily of the operations of WebBank. WebBank is a Utah chartered industrial bank subject to comprehensive regulation, examination and supervision by the Federal Deposit Insurance Corporation ("FDIC") and the State of Utah Department of Financial Institutions ("UDFI"). WebBank is not considered a "bank" for Bank Holding Company Act purposes and, as such, SPLP is not regulated as a bank holding company. WebBank's deposits are insured by the FDIC. WebBank engages in a full range of banking activities, including originating loans, issuing credit cards and taking deposits that are federally insured. WebBank originates and funds consumer and small business loans through lending programs with unaffiliated companies that market and service the programs ("Marketing Partners"), where the Marketing Partners subsequently purchase the loans (or interests in the loans) that are originated by WebBank. WebBank retains a portion of the loans it originates for its Marketing Partners. WebBank also has private-label financing programs that are branded for a specific retailer, manufacturer, dealer channel, proprietary network or bank card program. WebBank participates in syndicated commercial and industrial as well as asset-based credit facilities and asset-based securitizations through relationships with other financial institutions.

Corporate and Other Segment

The Corporate and Other segment consists of several consolidated subsidiaries, including Steel Services, equity method and other investments, and cash and cash equivalents. Its income or loss includes certain unallocated general corporate expenses. Steel Services has management services agreements with our consolidated subsidiaries and other related companies. For additional information on these service agreements see Note 20 - "Related Party Transactions" to the SPLP consolidated financial statements found elsewhere in this Form 10-K.

Business Strategy

We continuously evaluate the retention and disposition of existing operations and investigate possible acquisitions of new businesses, often focusing on businesses that are selling substantially below intrinsic value. We consider possible synergies and economies of scale in operating and/or making determinations to acquire or dispose of companies. We seek additional means to reduce costs and to encourage integration of operations and the building of business relationships among our companies, consistent with our desire that our unitholders benefit from the diversified holding company structure.

We strive to enhance the business operations of our companies and increase corporate value for unitholders and stakeholders through balance sheet improvements, strategic allocation of capital, and operational and growth initiatives. We use a set of tools and processes called the Steel Business System to drive operational and commercial efficiencies across each of our businesses. The Steel Business System utilizes a strategy deployment process to execute strategic initiatives for each of our businesses to improve their performance, including objectives relating to manufacturing improvement, idea generation, product development, and global sourcing of materials and services. Our operational initiatives include creating efficiencies through consolidated purchasing and materials sourcing provided by the Steel Partners Purchasing Council, which arranges shared purchasing programs and is reducing costs for, and providing other benefits to, a number of our companies. We are focused on reducing corporate overhead of our companies by centralizing certain administrative and corporate services through Steel Services, which provides management, consulting and advisory services.

Generally, we seek to actively acquire and maintain control over our companies through our ability to influence their policies. Depending on the size of our ownership interests in any given company, this may be achieved by obtaining board representation and overseeing and providing assistance to the existing management team. We generally view our companies as long-term holdings, and we expect to realize value by operating them with a view towards fostering growth and maximizing their value rather than through the sale of ownership interests. The securities of some of the companies in which we have interests are traded on national securities exchanges, while others are privately held or not actively traded.

Customers

The businesses within the Diversified Industrial segment are diversified across industrial markets and customers. Its businesses sell to customers in the construction, electrical, electronics, transportation, power control, utility, medical, oil & gas exploration, aerospace and defense, consumer products, packaging and food industries. No customer accounted for more than 10% of the Diversified Industrial segment's consolidated net sales in 2018 or 2017. The Diversified Industrial segment's 15 largest customers accounted for approximately 28% of consolidated Diversified Industrial segment net sales in 2018.

The Energy segment primarily provides its services to customers' extraction and production operations in North Dakota and Montana in the Bakken basin, Colorado and Wyoming in the Niobrara basin, Texas in the Permian basin and New Mexico in the San Juan basin. It relies primarily on its local operations to sell and market its services. In 2018, the Energy segment had two customers that made up 24% of its net revenue, and its top 15 customers made up 73% and 70% of its net revenue for the years ended December 31, 2018 and 2017, respectively.

4

In the Financial Services segment, WebBank earns interest income primarily from interest and fees earned on loans and investments, and it earns non-interest income primarily from origination fees earned on loans, fee income on contractual lending arrangements, premiums on the sale of loans and loan servicing fees. For the years ended December 31, 2018 and 2017, the two highest grossing contractual lending programs accounted for 29% and 40%, respectively, of WebBank's total revenue.

Raw Materials

The raw materials used by the businesses within the Diversified Industrial segment are as follows:

In addition to precious metals, the raw materials used in the Joining Materials, Tubing, Building Materials, Electrical Products and Kasco businesses consist principally of stainless, silicon and carbon steel, aluminum, copper, tin, nickel alloys, a variety of high-performance alloys, permanent magnets, electronic and electrical components, chemicals and various plastic compositions. The raw materials used in the operations of the Performance Materials business consist principally of fiberglass, quartz and aramid yarns. The raw materials used in the Packaging business consist principally of board, PET film, organic solvents, aluminum, resins, pigments and adhesives. Raw materials are generally purchased at open market prices from domestic and foreign suppliers. The Diversified Industrial segment businesses have not experienced any significant problem in obtaining the necessary quantities of raw materials. Prices and availability, particularly of raw materials purchased from foreign suppliers, are affected by world market conditions and government policies. The raw materials used by these businesses are generally readily available from more than one source.

The businesses in our Diversified Industrial segment also require significant amounts of electricity, oil & natural gas to operate their facilities, and they are subject to price changes in these commodities. A shortage of electricity, oil or natural gas, or a government allocation of supplies resulting in a general reduction in supplies, could increase costs of production and could cause some curtailment of production.

Capital Investments

SPLP believes that in order to be and remain competitive, its businesses must continuously strive to increase revenue, improve productivity and product quality, and control and/or reduce manufacturing costs. Accordingly, SPLP expects to continue to make capital investments that reduce overall manufacturing costs, improve the quality of products produced and services provided and broaden the array of products offered to the industries it serves, as well as replace equipment as necessary to maintain compliance with environmental, health and safety laws and regulations. SPLP's capital expenditures for 2018 and 2017 were $47,085 and $54,737, respectively. SPLP anticipates funding its capital expenditures in 2019 from funds generated by operations and borrowed funds.

Employment

As of December 31, 2018, the Company employed approximately 5,300 employees worldwide. Of these employees, 550 were covered by collective bargaining agreements, all in the Diversified Industrial segment. The Energy segment also hires additional full-time and part-time employees during peak seasonal periods.

Competition

There are many companies, larger and smaller, domestic and foreign, which manufacture products or provide services of the type offered by our businesses. Some of these competitors are larger and have financial resources greater than our subsidiaries. Some of these competitors enjoy certain other competitive advantages, including greater name recognition, greater financial, technical, marketing and other resources, a larger installed base of customers and well-established relationships with current and potential customers.

Competition in the Diversified Industrial segment is based on quality, technology, performance, service, reputation, price, and in some industries, new product introduction.

The Energy business operates in a highly competitive industry that is influenced by price, capacity, reputation and experience. In times of high demand, capacity, reputation and experience are major competitive forces. In times of low demand, service providers will compete on price to attract customers. In addition, they need to maintain a safe work environment and a well-trained work force to remain competitive. Energy services are affected by seasonal factors, such as inclement weather, fewer daylight hours and holidays during the winter months. Heavy snow, ice, wind or rain can make it difficult to operate and to move equipment between work sites, which can reduce its ability to provide services and generate revenues. These seasonal factors affect competitors

5

as well. Because they have conducted business together over several years, the members of our local operations have established strong working relationships with certain of their clients. These strong client relationships provide a better understanding of region-specific issues and enable us to better address customer needs. The market for Steel Sports' baseball facility services and soccer camps and leagues is very fragmented, and its competitors are primarily small local or regional operations.

WebBank competes with a broad range of banks, both larger and smaller, across its various lines of business.

Regulation

We are subject to many U.S. federal and state and foreign laws and regulations, including those related to environmental protection, labor, employment, worker health and safety, import and export, customs and tariffs, cybersecurity, intellectual property, privacy and protection of user data. WebBank is also subject to regulatory capital requirements administered by the FDIC and legal requirements in connection with the consumer and business lending programs that it originates.

These laws and regulations are constantly evolving and may be interpreted, applied, created or amended in a manner that could harm our business. We believe that we are in compliance in all material respects with all such laws and regulations and that we have obtained all material licenses and permits that are required for the operation of our business. For more information regarding regulatory risks, see the information in Part I, Item 1A, Risk Factors, of this Report.

Other Information

The amounts of revenue, earnings before taxes and identifiable assets attributable to the aforementioned business segments and additional information regarding SPLP's investments are included in Note 21 - "Segment Information" and Note 10 - "Investments" to the SPLP consolidated financial statements found elsewhere in this Form 10-K.

Our common units are quoted on the New York Stock Exchange under the symbol "SPLP." Our business address is 590 Madison Avenue, 32^nd Floor, New York, New York 10022, and our telephone number is (212) 520-2300. Our website is www.steelpartners.com. The information contained in, or that can be accessed through, the website is not part of this Form 10-K.This Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports, are available to you free of charge through our website as soon as reasonably practicable after those materials have been electronically filed with, or furnished to, the U.S. Securities and Exchange Commission ("SEC").

Item 1A. Risk Factors

Our business is subject to a number of risks. You should carefully consider the following risk factors, together with all of the other information included or incorporated by reference in this report, before you decide whether to purchase our common or preferred units. These factors are not intended to represent a complete list of the general or specific risks that may affect us. It should be recognized that other risks may be significant, presently or in the future, and the risks set forth below may affect us to a greater extent than indicated. If any of the following risks occur, our business, financial condition and results of operations could be materially adversely affected. In such case, the trading price of our common and preferred units could decline, and you may lose all or part of your investment.

The ordering of the risk factors set forth below is not intended to reflect any Company indication of priority or likelihood.

Risks Related to Our Business

Certain of the Company's subsidiaries sponsor defined benefit pension plans, which could subject the Company to substantial cash funding requirements in the future.

The Company's ongoing operating cash flow requirements include arranging for the funding of the minimum requirements of its subsidiaries' defined benefit pension plans. The Company is jointly and severally liable with Handy & Harman Ltd. and JPS Industries Holdings LLC for such subsidiaries' underfunded pension liabilities. The performance of the financial markets and interest rates, as well as health care trends and associated mortality rates, impact our defined benefit pension plan expense and funding obligations. Significant changes in these factors, including adverse changes in discount rates, investment losses on plan assets and increases in participant life expectancy, may increase our funding obligations and adversely impact our financial condition. Required future contributions are estimated based upon assumptions such as discount rates on future obligations, assumed rates of return on plan assets and legislative changes. Actual future pension costs and required funding obligations will be affected by changes in the factors and assumptions described in the previous sentence, as well as other changes such as any plan termination or other acceleration events. See the "Liquidity and Capital Resources" section of this Form 10-K for additional information.

We could incur significant costs, including remediation costs, as a result of complying with environmental laws or failing to comply with other extensive regulations, including banking regulations, that our businesses are subject to.

Our businesses are subject to extensive regulation by U.S. and non-U.S. governmental and self-regulatory entities at the federal, state and local levels, including laws related to anti-corruption, environmental matters, privacy matters, banking, health and safety, import laws and export control and economic sanctions, and the sale of products and services to government entities. Some of these laws and regulations pertain to the handling, storage and transportation of raw materials, products and wastes, and hazardous materials and wastes. Compliance with such requirements may make it necessary for us to retrofit existing facilities with additional pollution-control equipment, undertake new measures in connection with the storage, transportation, treatment and disposal of by-products and wastes or take other steps, which may be at a substantial cost to our subsidiaries. Although our subsidiaries maintain insurance coverage for certain environmental matters, they could incur substantial costs, including cleanup costs, fines or sanctions, and third-party claims for property damage or personal injury, as a result of violations of, or liabilities under, environmental laws. Any material violations of these laws can lead to substantial liability, revocations of discharge permits, fines or penalties, and any new laws, regulations and enforcement policies could become more stringent and significantly increase our compliance costs or limit our future business opportunities, negatively impacting our financial condition, business and results of operations.

In addition, the consumer and business lending programs offered by WebBank are subject to extensive legal requirements at the federal and state levels, described in more detail below. If WebBank or its programs do not comply with these laws, it may be subject to claims for damages, fines, penalties or other relief, and may face regulatory examination and enforcement action, and some violations could result in an underlying loan being found invalid or unenforceable, or subject to payment defenses.

Many of the customers in our Energy segment utilize hydraulic fracturing services, which is the process of creating or expanding cracks, or fractures, in formations underground where water, sand and other additives are pumped under high pressure into the formation. Although our Energy segment is not a provider of hydraulic fracturing services, many of its services complement the hydraulic fracturing process. Fracturing regulations vary widely because they are regulated at the state level. States continue to evaluate fracturing activities and their impact on the environment. Legislation for broader federal regulation of hydraulic fracturing operations and the reporting and public disclosure of chemicals used in the fracturing process could be enacted. Additionally, the United States Environmental Protection Agency has asserted federal regulatory authority over certain hydraulic fracturing activities involving diesel fuel under the Safe Drinking Water Act. Our Energy segment's customers' operations could be adversely affected if additional regulation or permitting requirements were to be required for hydraulic fracturing activities, which could have an adverse effect on our results of operations.

These are not the only regulations that our businesses must comply with. Failure to comply with these or any other regulations could result in civil and criminal, monetary and non-monetary penalties, damage to our reputation, disruptions to our business, limitations on our ability to manufacture, import, export and sell products and services, disbarment from selling to certain federal agencies, damage to our reputation and loss of customers and could cause us to incur significant legal and investigatory fees. Compliance with these and other regulations may also require us to incur significant expenses. The products and operations of our businesses are also often subject to the rules of industrial standards bodies such as the International Organization for Standardization (ISO), and failure to comply with these rules could result in withdrawal of certifications needed to sell our products and services and otherwise adversely impact our financial condition.

WebBank operates in a highly regulated environment, and its lending programs are subject to extensive federal and state regulation. Ongoing legislative and regulatory actions may significantly affect our liquidity or financial condition.

The consumer and business lending programs offered by WebBank are subject to extensive legal requirements at the federal and state levels. Among the laws that may be applicable to some or all of the programs offered by WebBank are:

• the Federal Truth-in-Lending Act and Regulation Z promulgated thereunder, which require certain disclosures to borrowers regarding the terms of their loans;

• the Dodd-Frank Wall Street Reform and Consumer Protection Act ("Dodd-Frank Act"), the Federal Trade Commission Act and state laws that prohibit unfair, deceptive, or abusive acts or practices;

• the Federal Equal Credit Opportunity Act and Regulation B promulgated thereunder, which prohibit discrimination in the extension of credit on the basis of age, race, color, sex, religion, marital status, national origin, receipt of public assistance or the exercise of any right under the Consumer Credit Protection Act;

• the Fair Credit Reporting Act, which governs the use of credit reports and the reporting of information to credit bureaus, and imposes restrictions on the marketing of credit products through prescreened solicitations based on credit report information;

7

• the Servicemembers Civil Relief Act and the Military Lending Act, which impose rate limitations and other requirements in connection with the credit obligations of active duty military personnel and certain of their dependents;

• federal and state laws relating to privacy and the safeguarding of personally identifiable consumer information and data breach notification;

• the Bank Secrecy Act, which relates to compliance with anti-money laundering, customer due diligence and record-keeping policies and procedures; and

• laws governing the permissibility of the interest rates and fees that are charged to borrowers.

The Dodd-Frank Act, which was signed into law in 2010, is intended primarily to overhaul the financial regulatory framework and impacts all financial institutions, including WebBank. The Dodd-Frank Act, among other things, established the Bureau of Consumer Financial Protection ("CFPB") and Financial Stability Oversight Council, consolidated certain federal bank regulators and imposed increased corporate governance and executive compensation requirements. The Economic Growth, Regulatory Relief, and Consumer Protection Act, which was signed into law in May 2018, amended the Dodd-Frank Act in some respects, but many of the requirements of the Dodd-Frank Act remain in effect. The extent and complexity of this regulatory framework and other regulations has increased WebBank's regulatory compliance burden and therefore has increased its regulatory risk.

If WebBank or its programs do not comply with these laws, it may be subject to claims for damages, fines, penalties or other relief, and may face regulatory scrutiny. In addition, some violations could result in an underlying loan being found invalid or unenforceable, or subject to payment defenses. Any of these violations could result in the imposition of liability on WebBank, although WebBank may have indemnification rights for certain claims. In addition, there could be limitations on WebBank's ongoing or future business.

WebBank offers lending programs through relationships with Marketing Partners. WebBank and its Marketing Partners are subject to supervision by the FDIC and the UDFI. The authority of the FDIC and the UDFI includes the ability to examine WebBank, the Marketing Partners and the programs. The FDIC and UDFI also may bring enforcement actions against WebBank and its Marketing Partners if they detect any violations of law. These enforcement actions could result in monetary liability on WebBank, increased compliance obligations or limitations on its ongoing and future business.

Other regulators, including the CFPB and the Federal Trade Commission ("FTC"), may bring investigations and enforcement actions against WebBank's Marketing Partners. In 2018, the FTC brought such an enforcement action against one of WebBank's Marketing Partners, which remains ongoing. These actions against Marketing Partners may increase WebBank's own regulators' scrutiny of WebBank's business and could result in an increased risk of investigations or claims being brought against WebBank.

The U.S. Congress and state legislatures and federal and state regulatory authorities continually review banking laws, regulations and policies for possible changes. We cannot predict whether additional legislation or regulations will be enacted and, if enacted, the effect that it would have on our business, financial condition or results of operations.

Future cash flows from operations or through financings may not be sufficient to enable the Company to meet its obligations, and this would likely have a material adverse effect on its businesses, financial condition and results of operations, and credit market volatility may affect our ability to refinance our existing debt, borrow funds under our existing lines of credit or incur additional debt.

There can be no assurances that the Company or its subsidiaries will continue to have access to their lines of credit if their financial performance does not satisfy the financial covenants set forth in the applicable financing agreements. If the Company or its subsidiaries do not meet certain of its financial covenants, and if they are unable to secure necessary waivers or other amendments from the respective lenders on terms acceptable to management, their ability to access available lines of credit could be limited, their debt obligations could be accelerated by the respective lenders and liquidity could be adversely affected.

If the Company's or its subsidiaries' cash needs are significantly greater than anticipated or they do not materially meet their business plans, or there are unanticipated downturns in the markets for the Company's and its subsidiaries' products and services, the Company or its subsidiaries may be required to seek additional or alternative financing sources. Future disruption and volatility in credit market conditions could have a material adverse impact on the Company's ability or that of its subsidiaries to refinance debt when it comes due on terms similar to our current credit facilities, or to draw upon existing lines of credit or incur additional debt if needed. There can be no assurance therefore that such financing will be available or available on acceptable terms. The inability to generate sufficient cash flows from operations or through financings could impair the Company's or its subsidiaries' liquidity and would likely have a material adverse effect on their businesses, financial condition and results of operations.

Our business strategy includes acquisitions, and acquisitions entail numerous risks, including the risk of management diversion and increased costs and expenses, all of which could negatively affect the Company's profitability.

Our business strategy includes, among other things, strategic acquisitions, as well as potential opportunistic acquisitions. This element of our strategy entails several risks, including the diversion of management's attention from other business concerns and the need to finance such acquisitions with additional equity and/or debt.

In addition, once completed, acquisitions entail further risks, including: unanticipated costs and liabilities of the acquired businesses, including environmental liabilities, that could materially adversely affect our results of operations; difficulties in assimilating acquired businesses, preventing the expected benefits from the transaction from being realized or achieved within the anticipating time frame; negative effects on existing business relationships with suppliers and customers; and losing key employees of the acquired businesses. If our acquisition strategy is not successful or if acquisitions are not well integrated into our existing operations, the Company's profitability could be negatively affected.

We may sustain losses in our investment portfolio, which could have an adverse effect on our results of operations, financial condition and liquidity.

A portion of our assets consists of equity securities which are adjusted to fair value each period, as well as other investments. An adverse change in economic conditions or setbacks unique to such companies, their operations or business models may result in a decline in the value of these investments. Such declines in value are principally recognized in net income or loss in accordance with current accounting principles generally accepted in the United States of America ("U.S. GAAP"). Any adverse changes in the financial markets and resulting declines in value of our investments may result in additional losses and could have an adverse effect on our results of operations, financial condition and liquidity.

Rising interest rates may negatively impact our investments and have an adverse effect on our business, financial condition, results of operations and cash flows.

In recent years, the Federal Reserve System ("Fed") has incrementally raised the target range for the federal funds rate, with additional increases expected to come over the next year. As interest rates increase, generally, the cost of borrowing increases, affecting our interest costs and ability to make new investments on favorable terms or at all. More generally, interest rate fluctuations and changes in credit spreads on floating rate loans may have a negative impact on our investments and investment opportunities and, accordingly, may have a material adverse effect on our rate of return on invested capital, our net investment income, our net asset value and the market price of our securities. In addition, an increase in interest rates may make it difficult or impossible to make payments on outstanding indebtedness. There can be no guaranty the Fed will raise rates at the gradual pace they originally proposed, nor can there be any assurance that the Fed will make sound decisions as to when to raise rates. The increase in interest rates could have a negative effect on our interest costs and investments, which could negatively impact our operating results, financial condition and cash flows.

As more fully described in Part II, Item 7A, Quantitative and Qualitative Disclosures About Market Risk, of this Report, WebBank derives a portion of its income from the excess of interest collected over interest paid. The rates of interest WebBank earns on assets and pays on liabilities generally are established contractually for a period of time. Market interest rates change over time. Accordingly, WebBank's results of operations, like those of most financial institutions, are impacted by changes in interest rates and the interest rate sensitivity of its assets and liabilities. WebBank monitors and measures its exposure to changes in interest rates in order to comply with applicable government regulations and to limit the risk that rising interest rates could have a negative impact on its results of operations. There can be no assurance, however, that, in the event of adverse changes in interest rates, WebBank's efforts to limit interest rate risk will be successful.

Our businesses rely, and may rely, on their intellectual property and licenses to use others' intellectual property, for competitive advantage. If our businesses are unable to protect their intellectual property, are unable to obtain or retain licenses to use others' intellectual property, or if they infringe upon or are alleged to have infringed upon others' intellectual property, it could have a material adverse effect on their financial condition, business and results of operations.

The success of each of our businesses depends in part on the trademarks and patents that they own, or their licenses to use others', brand names, proprietary technology and manufacturing techniques. In addition to trademark and patent protection, these businesses rely on copyrights, trade secrets, confidentiality procedures and contractual provisions to protect their intellectual property rights. The steps they have taken to protect their intellectual property rights may not prevent third parties from using their intellectual property without their authorization or independently developing intellectual property that is similar. In addition, the laws of foreign

9

countries may not protect our businesses' intellectual property rights effectively. Stopping unauthorized use of proprietary information and intellectual property, and defending claims of unauthorized use of others' proprietary information or intellectual property, may be difficult, time-consuming and costly and could subject our businesses to significant liability for damages and invalidate their property rights. Such unauthorized use could reduce or eliminate any competitive advantage our businesses have developed, cause them to lose sales or otherwise harm their business.

We conduct business outside of the U.S., which may expose us to additional risks not typically associated with companies that operate solely in the U.S.

We conduct business and have operations or own interests in securities of companies with operations outside the U.S. These operations have additional risks, including risks relating to currency exchange, less developed or efficient financial markets than in the U.S., absence of uniform accounting, auditing and financial reporting standards, differences in the legal and regulatory environment, different publicly available information in respect of companies in non-U.S. markets, economic and political risks, and possible imposition of non-U.S. taxes. There can be no assurance that adverse developments with respect to such risks will not adversely affect our assets that are held in certain countries or the returns from these assets.

We also face several risks inherent in conducting business internationally, including compliance with international and U.S. laws and regulations that apply to our international operations. These laws and regulations include data privacy requirements, labor relations laws, tax laws, anti-competition regulations, import and trade restrictions, U.S. laws such as export control laws and the Foreign Corrupt Practices Act, and similar laws in other countries which also prohibit corrupt payments to governmental officials or certain payments or remunerations to customers. Given the high level of complexity of these laws, there is a risk that some provisions may be inadvertently breached. Also, we may be held liable for actions taken by our local partners. Violations of these laws and regulations could result in fines, criminal sanctions against us, our officers or our employees, and prohibitions on the conduct of our business. Any such violations could include prohibitions on our ability to offer our products and services in one or more countries.

Recent and potential changes in U.S. trade policies and retaliatory responses from other countries may significantly increase the costs or limit supplies of materials and products used in our operations.

The federal government has recently imposed new or increased tariffs or duties on an array of imported materials and goods that are used in connection with our operations. Foreign governments, including China and Canada, and trading blocs, such as the European Union ("EU"), have responded by imposing or increasing tariffs, duties and/or trade restrictions on U.S. goods, and are reportedly considering other measures. These trade conflicts and related escalating governmental actions that result in additional tariffs, duties and/or trade restrictions could increase our operating costs, cause disruptions or shortages in our supply chains and/or negatively impact the U.S., regional or local economies, and, individually or in the aggregate, materially and adversely affect our business and our consolidated financial statements.

The exit of the United Kingdom from the European Union could have future adverse effects on our operations revenues and costs, and therefore our profitability.

The referendum held in the United Kingdom on June 23, 2016 resulted in a determination that the United Kingdom should exit the EU. In March 2017, the United Kingdom government initiated the exit process under Article 50 of the Treaty of the EU, commencing a period of up to two years for the United Kingdom and the other EU member states to negotiate the terms of the withdrawal. The uncertainty surrounding the timing, terms and consequences of the United Kingdom's exit could adversely impact our operations in the United Kingdom. Some of our facilities are located in the United Kingdom, and these facilities, as well as others in our network, source goods, manufacture goods and provide services from or intended for the United Kingdom. These facilities operate within an existing framework of trade and human capital integration with the EU and, by extension, the other parts of the world, with which the EU has trade and immigration agreements. Furthermore, some of our facilities located in other EU member states ship materials to or otherwise engage in various business interactions with the United Kingdom, including our United Kingdom facilities. Due to future changes in the United Kingdom resulting from an eventual exit, including potentially increased trade barriers, increased tariff rates or custom duties, or in anticipation of such changes, our suppliers, customers, or employees may change their interactions with us, including changes in imports to or exports from the United Kingdom, changes in the requested utilization of our facilities, both within and without the United Kingdom, and changes in our relationships with our workforce in the United Kingdom. To the extent that our facilities operate as part of a cross-border supply and distribution chain, their operations may also be negatively affected by a decrease in the cross-border mobility of goods and services. We cannot anticipate the nature of these changes, as they largely depend on factors outside our control, but the changes may result in adverse changes in our future operations, revenues and costs, and therefore our future profitability.

10

A significant disruption in, or breach in security of, our information technology systems could adversely affect our business.

We rely on information technology systems, some of which are managed by third parties, to process, transmit and store electronic information, and to manage or support a variety of critical business processes and activities. We also collect and store sensitive data, including confidential business information and personal data. These systems may be susceptible to damage, disruptions or shutdowns due to attacks by computer hackers, computer viruses, employee error or malfeasance, power outages, hardware failures, telecommunication or utility failures, catastrophes or other unforeseen events. Upgrading our information technology systems is costly and subject to delay, and there is no assurance new systems will provide the benefits expected. In addition, security breaches of our systems could result in the misappropriation or unauthorized disclosure of confidential information or personal data belonging to us or to our employees, partners, customers or suppliers. Any such events could disrupt our operations, delay production and shipments, result in defective products or services, damage customer relationships and our reputation and result in legal claims or proceedings, liability or penalties under privacy laws, each of which could adversely affect our business and our financial condition. State and federal laws may also require us to provide notice to affected individuals if their personal data is the subject of a breach in security, which would impose costs and could lead to additional liability and negative publicity. We take cybersecurity seriously and devote significant resources and tools to protect our systems, products and data and to prevent unwanted intrusions. However, these security efforts are costly to implement and may not be successful. There can be no assurance that we will be able to prevent, detect and adequately address or mitigate such cyber-attacks or security breaches. Any such breach could have a material adverse effect on our operations and our reputation and could cause irreparable damage to us or our systems, regardless of whether we or our third-party providers are able to adequately recover critical systems following a systems failure. In addition, regulatory or legislative action related to cybersecurity, privacy and data protection worldwide, such as the European General Data Protection Regulation, which went into effect in May 2018, may increase the costs to develop, implement or secure our products and services. We expect cybersecurity regulations to continue to evolve and be costly to implement.

Labor disputes may have an adverse effect on the Company's business.

Some of our subsidiaries are party to collective bargaining agreements with various labor unions in the United States and internationally. We may be subject to, among other things, strikes, work stoppages or work slowdowns as a result of disputes under these collective bargaining agreements and labor contracts or our potential inability to negotiate acceptable contracts with these unions. If the unionized workers in the United States or internationally were to engage in astrike, work stoppage or other slowdown; if other employees were to become unionized or if the terms and conditions in future labor agreements were renegotiated, we could experience a significant disruption in our operations and incur higher ongoing labor costs.

WebBank's status as lender of the loans it offers, and the ability of assignees to collect interest, may be challenged, and these challenges could negatively impact WebBank's ongoing and future business.

WebBank's business includes lending programs with Marketing Partners, where the Marketing Partners provide origination servicing for the loans and subsequently purchase the loans (or interests in the loans) that are originated by WebBank. There have been litigation and regulatory actions which have challenged lending arrangements where a bank has made a loan and then sold and assigned it to an entity that is engaged in assisting with the origination and servicing of the loan. Some of these cases have alleged that the marketing and servicing entity should be viewed as the "true creditor" of the loans originated through the lending program, and the bank should be disregarded. If this type of challenge is successful, state law interest rate limitations and other requirements that apply to non-bank lenders would then be applicable, instead of the federal interest rate laws that govern bank lenders. Other cases have relied on the claim that even if a bank originated a loan based on the federal interest rate laws, an assignee of a bank is not permitted to rely on the federal law and is instead subject to state law limitations. Certain of these challenges have been brought or threatened in programs involving WebBank, including a pending lawsuit against one of WebBank's Marketing Partners brought by the Administrator of the Uniform Consumer Credit Code in Colorado. WebBank has intervened in that litigation, which remains pending. Such cases or regulatory actions, if successfully brought against WebBank or its Marketing Partners or others could negatively impact WebBank's ongoing and future business. WebBank continues to structure its programs, and to exercise control over these programs, to address these risks, although there can be no assurance that additional cases or regulatory actions will not be brought in the future.

The Volcker Rule, which is part of the Dodd-Frank Act, restricts SPLP's flexibility to do business.

The Dodd-Frank Act added a new Section 13 to the Bank Holding Company Act, the so-called "Volcker Rule," which generally restricts certain banking entities (including affiliates of depository institutions) from engaging in proprietary trading activities and acquiring or retaining ownership interests in, or sponsoring, any private equity or hedge fund (collectively, "covered funds"). Under the implementing regulations, WebBank and its affiliates are restricted from engaging in proprietary trading, or

11

investing in or sponsoring covered funds, unless their activities qualify for a specific exclusion or exemption under the rule. Because SPLP controls WebBank, each of SPLP and all its subsidiaries, as well as its controlled entities, are banking entities under the Volcker Rule and therefore subject to the same restrictions. In June 2018, and again in December 2018, the federal agencies responsible for implementing the Volcker Rule proposed further revisions to the existing regulations implementing the Volcker Rule. The substance and timing of any final rules that will be implemented based on these proposals is not yet known. Changes to the regulations implementing the Volcker Rule could require changes to the business of WebBank, SPLP or any of their affiliates, which may have the effect of restricting the business or increasing regulatory risk.

WebBank is subject to capital requirements, and SPLP could be called upon by the FDIC to infuse additional capital into WebBank to the extent that WebBank fails to satisfy its capital requirements.

In July 2013, the Federal Reserve Board, the Office of the Comptroller of the Currency and the FDIC issued rules that implemented the Basel III changes to the international regulatory capital framework and revised the U.S. risk-based and leverage capital requirements for U.S. banking organizations in order to strengthen identified areas of weakness in capital rules and to address relevant provisions of the Dodd-Frank Act.

Effective January 1, 2015 for WebBank, FDIC regulations implementing the Basel III Accord modified WebBank's minimum capital requirements by defining what constitutes capital for regulatory capital purposes and adding a 4.5% Common Equity Tier 1 ratio and increased the Tier 1 capital ratio requirement from 4% to 6%. FDIC regulations also require WebBank to comply with a total capital ratio of 8% and a leverage ratio of 4%. Additionally, a Capital Conservation Buffer (composed solely of common equity Tier 1 capital) equal to 2.5% above the new regulatory minimum capital requirements began to be phased in starting January 1, 2016 and has been fully implemented as of January 1, 2019. The Capital Conservation Buffer is on top of the minimum risk-weighted capital ratios and had the effect of increasing those ratios by 2.5% each. A failure of WebBank to maintain the aggregate minimum capital required by the Capital Conservation Buffer will impair its ability to make certain distributions (including dividends and stock repurchases) and discretionary bonus payments to executive officers. A failure of WebBank to maintain capital as required by the FDIC's minimum capital requirements would subject WebBank to the FDIC's prompt corrective action regime, which may further impair WebBank's ability to make payments or distributions and may require a capital restoration plan or other corrective regulatory measures.

Federal banking agencies jointly issued a proposed rule on September 27, 2017 that would simplify the treatment of certain assets and deductions for institutions such as WebBank that are not subject to the so-called "advanced approaches" capital rule. The proposed rule would adjust the deduction thresholds for certain mortgage servicing assets, deferred tax assets, investments in the capital of unconsolidated financial institutions and minority interests. While the banking agencies consider comments on the proposed rule, the banking agencies adopted a rule on November 21, 2017, that provides interim relief to non-advanced approaches banking organizations by extending the regulatory capital transition periods effective in 2017 for certain items, including regulatory capital deductions, risk weights and certain minority interest limitations.

The Company currently cannot predict the specific impact and long-term effects that Basel III and its implementation in the U.S. will have on WebBank and the banking industry more generally. Furthermore, the Dodd-Frank Act codified a longstanding policy that all companies that directly or indirectly control an FDIC-insured bank are required to serve as a source of financial strength for such institution. As a result, SPLP could be called upon by the FDIC to infuse additional capital into WebBank to the extent that WebBank fails to satisfy its capital requirements, including at times that SPLP might not otherwise be inclined to provide it and even if doing so may adversely affect SPLP's ability to meet its other obligations, which include limitations on capital contributions to WebBank specified in the Company's senior secured revolving credit facility.

WebBank's lending programs depend on relationships with Marketing Partners.

WebBank offers its lending programs with Marketing Partners. If those Marketing Partners do not provide origination services or other services to WebBank, or provide those services in a faulty manner, that may negatively impact WebBank's ongoing and future business. In addition, if the Marketing Partners or other third parties do not purchase the loans (or interests in loans) that are originated by WebBank, then WebBank may need to retain those loans (or interests in loans) and that may negatively impact its ongoing and future business. Marketing Partners are also required to indemnify WebBank for certain liabilities that may arise from the lending programs. If Marketing Partners are unable or unwilling to satisfy their indemnification obligations, then WebBank would face increased risk from liability for claims made in private litigation or regulatory enforcement actions. Marketing Partners may rely on outside sources of capital to meet their obligations. Market conditions and other factors may affect the availability of capital for Marketing Partners. The availability of capital may also affect the volume of loans that can be originated through WebBank's lending programs. In recent periods, the availability of capital has been more limited for several of WebBank's Marketing Partners, resulting in a decrease in loan volume and a negative impact on WebBank's business.

Economic downturns could disrupt and materially harm our businesses.

Negative trends in the general economy, including rising interest rates and commodity prices, could cause a downturn in the markets for our products and services. A significant portion of our revenues in the Diversified Industrial segment are received from customers in transportation, oil & gas exploration, and construction-related industries, which have experienced significant financial downturns in the past. These industries are cyclical and demand for their products tends to fluctuate due to changes in national and global economic conditions, availability of credit and other factors. A worsening of customer demand in these industries would adversely affect our revenues, profitability, operating results and cash flows. In our Energy segment, the level of oil & natural gas exploration and production activity in the U.S. is affected by the price of oil. Reduced discovery rates of new oil & natural gas reserves, or a decrease in the development rate of reserves in our market areas, weakness in oil & natural gas prices, or our customers' perceptions that oil & natural gas prices will decrease in the future, could result in a reduction in the utilization of our equipment and result in lower revenues or rates for the services of our Energy segment. Our customers' willingness to undertake these activities depends largely upon prevailing industry conditions that are influenced by many factors over which we have no control. Our Financial Services segment could be impacted by tightening of the credit markets and other general economic declines that could result in a decrease in lending and demand for consumer loans. We may also experience a slowdown if some customers experience difficulty in obtaining adequate financing due to tightness in the credit markets. Furthermore, the financial stability of our customers or suppliers may be compromised, which could result in additional bad debts for us or non-performance by suppliers. Our assets may also be impaired or subject to write-down or write-off as a result of these conditions. These adverse effects would likely be exacerbated if global economic conditions worsen, resulting in wide-ranging, adverse and prolonged effects on general business conditions, and materially and adversely affect our operations, financial results and liquidity.

Our subsidiaries do not have long-term contracts with all of their customers, and the loss of customers with which we do not have long-term contracts could materially adversely affect our financial condition, business and results of operations.

Our businesses are based primarily upon individual orders, sales and service agreements with customers and not long-term contracts. As such, these customers could cease buying products or using our services at any time and for any reason, and we will have no recourse in the event a customer no longer wants to purchase products from us or use our services. If a significant number of our customers elect not to purchase products or use our services, or we have to make price concessions in order to retain certain customers, it could materially adversely affect our financial condition, business and results of operations.

Litigation or compliance failures could adversely affect our profitability.

The nature of our businesses and our investment strategies expose us to various litigation matters. We contest these matters vigorously and make insurance claims where appropriate. However, litigation is inherently costly and unpredictable, making it difficult to accurately estimate the outcome of any litigation. These lawsuits may include claims for compensatory damages, punitive and consequential damages and/or injunctive relief. The defense of these lawsuits may divert our management's attention, we may incur significant expenses in defending these lawsuits, and we may be required to pay damage awards or settlements or become subject to equitable remedies that could adversely affect our operations and financial condition. Moreover, any insurance or indemnification rights that we may have may be insufficient or unavailable to protect us against such losses. In addition, developments in legal proceedings in any given period may require us to adjust the loss contingency estimates that we have recorded in our consolidated financial statements, record estimates or reserves for liabilities or assets previously not susceptible of reasonable estimates or pay cash settlements or judgments. Any of these developments could adversely affect our financial condition in any particular period. Although we make accruals as we believe warranted, the amounts that we accrue could vary significantly from any amounts we actually pay due to the inherent uncertainties in the estimation process. See the "Litigation Matters" included in Note 19 - "Commitments and Contingencies" to Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Report for additional information.

Our internal controls over financial reporting may not be effective, and our independent registered public accounting firm may not be able to certify as to their effectiveness, which could have a significant and adverse effect on our business and reputation.

We are subject to the requirements of Section 404 of the Sarbanes-Oxley Act of 2002 and the rules and regulations of the SEC thereunder ("Section 404"). Section 404 requires us to report on the design and effectiveness of our internal controls over financial reporting. Section 404 also requires an independent registered public accounting firm to test our internal controls over financial reporting and report on the effectiveness of such controls. There can be no assurance that our independent registered public accounting firm will issue an unqualified report attesting to our internal controls over financial reporting. As a result, there could

13

be a negative reaction in the financial markets due to a loss of confidence in the reliability of our consolidated financial statements or our consolidated financial statements could change.

Any failure to maintain or implement new or improved controls, or any difficulties we encounter in their implementation, could result in significant deficiencies or material weaknesses, and cause us to fail to meet our periodic reporting obligations, or result in material misstatements in our consolidated financial statements. We may also be required to incur costs to improve our internal control system and hire additional personnel. This could negatively impact our results of operations.

Risks Related to Our Structure

The unitholders have limited recourse to maintain actions against the General Partner, the Board of Directors, our officers and the Manager.

The Limited Partnership Agreement of SPLP, or the "Partnership Agreement," contains broad indemnification and exculpation provisions that limit the right of a unitholder to maintain an action against the General Partner, the Board of Directors, our officers and the Manager, or to recover losses or costs incurred due to action or inaction by these parties which have a negative effect on the Company.

Our Partnership Agreement contains certain provisions that may limit the voting rights of some unitholders.

Our Partnership Agreement contains specific provisions that are intended to comply with regulatory limitations on the ownership of our securities as a result of our ownership of WebBank. Under the Partnership Agreement, a person or group that acquires beneficial ownership of 10% or more of the common units without the prior approval of the Board of Directors may lose voting rights with respect to all of its common units in excess of 9.9%.

We may have conflicts of interest with the minority shareholders of our businesses and decisions may need to be made by disinterested directors, without the participation of directors or officers associated with the Manager and the Company. These decisions may be different from the decisions we would make, and may or may not be in the best interests of our unitholders.

Because we own less than 100% of certain affiliates, and we may engage in transactions with these affiliates from time to time, the boards of directors and officers of those businesses, including directors and officers associated with our Manager and the Company, have fiduciary duties to their respective shareholders. As a result, they may make decisions that are in the best interests of their shareholders generally but which are not necessarily in the best interest of our unitholders. In dealings with us, the directors and officers of our businesses may have conflicts of interest and decisions may have to be made without their participation. Such decisions may be different from the decisions we would make and may not be in the best interests of our common and preferred unitholders, which may have an adverse effect on our business and results of operations.

There are certain interlocking relationships among us and certain affiliates of Warren G. Lichtenstein, our Executive Chairman, which may present potential conflicts of interest.

Warren G. Lichtenstein, our Executive Chairman and a substantial unitholder, is the Chief Executive Officer of our Manager. As of December 31, 2018, Mr. Lichtenstein directly owned approximately 4.1% of our outstanding common units. In addition, affiliates of our Manager, including Mr. Lichtenstein, beneficially own approximately 55.5% of our outstanding common units, although Mr. Lichtenstein disclaims beneficial ownership of any common units not directly held by him. We have entered into transactions and/or agreements with these entities. There can be no assurance that such entities will not have interests in conflict with our own.

Certain members of our management team may be involved in other business activities that may involve conflicts of interest, possibly diverting their attention from the Company's operations.

Certain individual members of our management team, including Warren G. Lichtenstein, our Executive Chairman, and Jack L. Howard, our President, may from time to time be involved in the management of other businesses, including those owned or controlled by our Manager and its affiliates. Accordingly, these individuals may focus a portion of their time and attention on managing these other businesses. Conflicts may arise in the future between our interests and the interests of the other entities and business activities in which such individuals are involved.

Risks Related to Our Manager

14

We depend on Warren G. Lichtenstein, the Chairman and Chief Executive Officer of the Manager, and Jack L. Howard, the President of the Manager, in running our businesses. The loss of their services could have a material adverse effect on our business, results and financial condition.

Our success depends on the efforts, skills, reputation and business contacts of Warren G. Lichtenstein, the Chairman and Chief Executive Officer of the Manager and Jack L. Howard, the President of the Manager. While the key members of the Manager have worked for the Manager and its affiliates for many years, our Manager does not have any employment agreements with any of the key members of its management team, and their continued service is not guaranteed. The loss of the services of Mr. Lichtenstein or Mr. Howard could have a material adverse effect on our asset value, revenues, net income and cash flows and could harm our ability to maintain or grow our existing operations or pursue additional opportunities in the future.

We cannot determine the amount of the Management Fee that will be paid or Class C partnership units that will be issued over time with any certainty.

The Manager receives a fee ("Management Fee") at an annual rate of 1.5% of total partners' capital. Our total partners' capital will be impacted by the performance of our businesses and other businesses we may acquire in the future, as well as the issuance of additional common or preferred units. Changes in our total partners' capital and in the resulting Management Fee could be significant, resulting in a material adverse effect on our results of operations. In addition, if our performance declines, assuming our total partners' capital remains the same, the Management Fee will increase as a percentage of our income. In addition, SPH SPV-I LLC, an affiliate of the Manager, holds partnership profits interests in the form of incentive units which entitle the holder generally to share in 15% of the increase in the equity value of the Company, as calculated for the twenty trading days prior to each year end. The incentive units' share of such appreciation is reflected by classifying a portion of the incentive units as Class C units of the Company. Any issuance of such Class C units will result in dilution to existing limited partners' holdings in the Company.

Our Manager's liability is limited under the Management Agreement, and we have agreed to indemnify our Manager against certain liabilities. Such indemnification may incentivize our Manager to take unnecessary risks with respect to actions for which it will be indemnified.

Under the Management Agreement, our Manager, its members, officers, employees, affiliates, agents and legal representatives are not liable for, and we have agreed to indemnify such persons from, any loss or expense, including without limitations, any judgment, settlement, reasonable attorneys' fees and other costs and expenses incurred in connection with the defense of any actual or threatened proceeding, other than losses resulting from willful misconduct or gross negligence in the performance of such indemnified person's obligations and duties. Such indemnification may incentivize our Manager to take unnecessary risks with respect to actions for which it will be indemnified.

Risks Related to our Common and Preferred Units

We may issue additional common or preferred units, or other series of units, in the future without the consent of unitholders and at a discount to the market price of such units. In particular, sales of significant amounts of the common or preferred units may cause the respective prices of the units to decline.

Under the terms of the Partnership Agreement, additional common or preferred units, or additional series of units, may be issued without the consent of unitholders at a discount to the market price. In addition, other classes of securities may be issued with rights that are senior to or which otherwise have preferential rights to the rights of the common and preferred units. Sales of significant amounts of the common or preferred units in the public market or the perception that such sales of significant amounts may occur could adversely affect their respective market prices. Moreover, the perceived risk of any potential dilution could cause common or preferred unitholders to attempt to sell their units and investors to "short" the common or preferred units, a practice in which an investor sells units that he or she does not own at prevailing market prices, hoping to purchase units later at a lower price to cover the sale. Any event that would cause the number of common or preferred units being offered for sale to increase would likely cause the respective units' market price to further decline. These sales might also make it more difficult for us to sell additional common or preferred units in the future at a time and price that we deem appropriate.

Transfer restrictions contained in the Company's Partnership Agreement and other factors could hinder the development of an active market for our common or preferred units.

There can be no assurance as to the volume of our common or preferred units or the degree of price volatility for our common and preferred units traded on the New York Stock Exchange. There are transfer restrictions contained in the Company's Partnership Agreement to help protect net operating tax loss carryforwards of certain of the Company's corporate subsidiaries and

15

other portfolio companies. The transfer restrictions will expire on February 7, 2020, and they could hinder development of an active market for our common and preferred units.

Risks Related to Taxation

All statutory references in this section are to the Internal Revenue Code of 1986, as amended, or the "Code."

Our common unitholders may be subject to U.S. federal, state and other income tax on their share of our taxable income, regardless of whether they receive any cash distributions from us.

The Company operates, for U.S. federal income tax purposes, as a partnership and not a publicly traded partnership taxable as a corporation. Our common unitholders will be subject to U.S. federal, state, local and possibly, in some cases, foreign income tax on their allocable share of our taxable income, whether or not they receive cash distributions from us. Any future determination to declare dividends on the Company's common units will remain at the discretion of the Board of Directors and is separately determined regardless of the allocation of taxable income. Accordingly, our common unitholders may be required to make tax payments in connection with their ownership of common units that significantly exceed their cash distributions in any given year.

The Centralized Partnership Audit Regime may subject unitholders to IRS initiated tax adjustments for prior years on their personal tax returns.

For tax years beginning on or after January 1, 2018, the Company is subject to partnership audit rules enacted as part of the Bipartisan Budget Act of 2015 ("Centralized Partnership Audit Regime"). Under the Centralized Partnership Audit Regime, any Internal Revenue Service ("IRS") audit of the Company would be conducted at the Company level, and if the IRS determines an adjustment, the default rule is that the Company would pay an "imputed underpayment" including interest and penalties, if applicable. The Company may instead elect to make a "push-out" election, in which case the partners for the year that is under audit would be required to take into account the adjustments on their own personal income tax returns.

Newly enacted U.S. government tax reform could have a negative impact on the results of future operations.

On December 22, 2017, the U.S. Tax Cuts and Jobs Act ("Act") was enacted which contained substantial changes to the Code, some of which could have an adverse effect on our business. Among other things, the Act (i) reduces the U.S. corporate income tax rate from 35% to 21% beginning in 2018, (ii) generally will limit annual deductions for interest net expense to no more than 30% of our "adjusted taxable income," plus 100% of our business interest income for the year, and (iii) will permit a taxpayer to offset only 80% (rather than 100%) of its taxable income with any U.S. net operating losses ("NOLs") generated for taxable years beginning after 2017. The U.S. Department of the Treasury has broad authority to issue regulations and interpretative guidance that may significantly impact how we will apply the law and impact our results of operations in the period issued. While the U.S. Department of the Treasury has issued some proposed regulations since the enactment of the Act, additional guidance is likely forthcoming. The measurement period allowed by SEC Staff Accounting Bulletin No. 118 has closed during the fourth quarter of 2018 in which we recorded an income tax benefit of $1,896 related to the one-time mandatory repatriation tax. The prospects of supplemental legislation or regulatory processes to address uncertainties that arise because of the Act, or evolving technical interpretations of the tax law, may cause our consolidated financial statements to be impacted in the future. We will continue to analyze the effects of the Act as subsequent guidance continues to emerge.

Our tax treatment is not assured. If we are taxed as a corporation, it could adversely impact our results of operations.

A partnership is not a taxable entity, and distributions by a partnership to a partner are generally not taxable to the partnership or the partner unless the amount of cash distributed to such partner exceeds the partner's adjusted basis in its partnership interest. Section 7704 provides that generally publicly traded partnerships are taxed as corporations. However, an exception, referred to as the "Qualifying Income Exception," exists with respect to publicly traded partnerships of which 90 percent or more of the gross income for every taxable year consists of "qualifying income" as defined in the Code. We expect that we will meet the Qualifying Income Exception.

If the Qualifying Income Exception is not available to us, then we will be treated as a corporation instead of a partnership. In that event, the deemed incorporation of SPLP should be tax-free. If we were taxed as a corporation, (i) our net income would be taxed at corporate income tax rates, thereby substantially reducing our profitability, (ii) our common unitholders would not be allowed to deduct their share of losses of SPLP and (iii) distributions to our common unitholders, other than liquidating distributions, would constitute dividends to the extent of our current or accumulated earnings and profits, and would be taxable as such.

16

Our structure involves complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available.

The U.S. federal income tax treatment of our common unitholders depends in some instances on interpretations of complex provisions of U.S. federal income tax law for which no clear precedent or authority may be available. Our Partnership Agreement permits our General Partner to modify it from time to time, including the allocation of items of income, gain, loss and deduction (including unrealized gain and unrealized loss to the extent allowable under U.S. federal income tax law), without the consent of our unitholders, to address certain changes in U.S. federal income tax regulations, legislation or interpretation or to preserve the uniformity of our common units. In some circumstances, such revisions could have a material adverse impact on some or all common unitholders. In addition, we formed a subsidiary partnership, to which we contributed certain of our assets ("Subsidiary Partnership"). To preserve the uniformity of common units, we (but not the Subsidiary Partnership) made an election permitted under Section 754, and we will adopt the remedial allocation method under Section 704(c) with respect to items of income, gain, loss and deduction attributable to assets contributed to us (which we will contribute to the Subsidiary Partnership), to account for any difference between the tax basis and fair market value of such assets at the time of contribution, or attributable to the "book-up" or "book-down" of our assets prior to their contribution to the Subsidiary Partnership, or while they were held by the Subsidiary Partnership, to account for the difference between the tax basis and fair market value of such assets at the time of a mark-to-market event. We intend generally to make allocations under Section 704(c) to our common unitholders in accordance with their respective percentage interests. However, built-in gain or built-in loss in existence and allocable to the assets we contributed to the Subsidiary Partnership, when recognized, will be allocated to our common unitholders as of the contribution date. We intend to prepare our tax returns on the basis that buyers of common units from such unitholders will not inherit such unitholders' built-in gains or built-in losses as of that date as a result of the election under Section 754. However, it is not clear whether this position will be upheld if challenged by the IRS. While we believe it represents the right result, there is no law directly on point.

Tax-exempt entities face unique tax issues from owning common units that may result in adverse tax consequences to them.

A holder of common units that is a tax-exempt organization may be subject to U.S. federal income taxation to the extent that its allocable share of our income consists of unrelated business taxable income ("UBTI"). A tax-exempt partner of a partnership may be treated as earning UBTI if the partnership regularly engages in a trade or business that is unrelated to the exempt function of the tax-exempt partner, if the partnership derives income from debt-financed property (as we may borrow money) or if the tax-exempt organization's partnership interest itself is debt-financed.

Our subsidiaries may not be able to fully utilize their tax benefits, which could result in increased cash payments for taxes in future periods.

NOLs may be carried forward to offset federal and state taxable income in future years and reduce the amount of cash paid for income taxes otherwise payable on such taxable income, subject to certain limits and adjustments. If fully utilized, our subsidiaries' NOLs and other carryforwards could provide them with significant tax savings in future periods. Their ability to utilize these tax benefits in future years will depend upon their ability to generate sufficient taxable income and to comply with the rules relating to the preservation and use of NOLs, as well as potential future changes in tax laws. The potential benefit of the NOLs and other carryforwards may be limited or permanently lost as a result of the following:

• the inability to generate sufficient taxable income in future years to use such benefits before they expire as NOLs generated for taxable years ending on or before December 31, 2017 have a limited carryforward period;

• a change in control of our subsidiaries that would trigger limitations on the amount of taxable income in future years that may be offset by NOLs and other carryforwards that existed prior to the change in control; and

• examinations and audits by the IRS and other taxing authorities could reduce the amount of NOLs and other credit carryforwards that are available for future years.

Certain of our subsidiaries maintain valuation allowances against their NOLs and other carryforwards due to uncertainty regarding their ability to generate sufficient taxable income in future periods. Their inability to utilize the NOLs and other carryforwards could result in increased cash payments for taxes in future periods.

For a more complete description of the Company's segments, see Item 1 - "Business - Products and Product Mix" found elsewhere in this Form 10-K.

Recent Developments

Below is a summary of recent developments that have impacted the Company in 2018 and early 2019. For additional discussion of these matters, please see the Company's Consolidated Financial Statements, included in Part II, Item 8, Financial Statements and Supplementary Data, of this Report.

• On February 16, 2018, the Company completed the Dunmore acquisition for a purchase price of $69,604, which includes assumed debt and is subject to an earn-out based on future earnings during the period from January 1, 2018 through December 31, 2019. Dunmore manufactures and distributes coated, laminated and metallized films for engineered applications in the imaging, aerospace, insulation and solar photo-voltaic markets and also provides products for custom and special applications.

• During 2018, the Company entered into purchase agreements with minority stockholders of its subsidiary, WebFinancial Holding Corporation ("WFHC"), pursuant to which the Company purchased shares of common and preferred stock of WFHC in exchange for aggregate consideration totaling approximately $20,680, comprised of cash of $13,708, 185,407 SPLP common units and 186,271 SPLP preferred units. WFHC is the parent of WebBank, API and Dunmore. As a result of these transactions, the Company now owns 100% of WFHC.

• On June 1, 2018, the Company completed the acquisition of PST for approximately $4,620. PST manufactures precision-engineered threaded components and custom ball screw assemblies, providing linear motion and power transmission solutions across a range of industries.

• On December 31, 2018, the Company increased its ownership in iGo, Inc. ("iGo") from 45.8% to 80.2% by contributing its Kasco business to iGo in exchange for newly issued shares of iGo common stock.

20

• WebBank entered into a definitive agreement in December 2018 to purchase National Partners PFco, LLC, a national insurance premium finance company. The transaction is expected to close in early 2019, subject to regulatory approval.

• The Company made investments totaling $76,261 in Babcock & Wilcox Enterprises, Inc. ("BW") shares during 2018, increasing its ownership in BW to approximately 17.8%.

• In both 2018 and early 2019, the Company entered into amendments to its senior secured revolving credit facility to increase availability, allowing for continued growth through strategic acquisitions and other investments.

• Throughout 2018, the Company continued its focus to optimize infrastructure costs, consolidating operations in both its Electrical Products and Packaging businesses. Continued focus on cost reduction and organic growth through new product development will be critical given recent sales declines in the Packaging business discussed further below.

• We made investments in capital projects totaling $47,085, including expenditures associated with the aforementioned plant consolidations, as well as upgrades in our information technology infrastructure as we continue to automate our operations.

• In November 2018, the Board of Directors approved the repurchase of up to an additional 1,000,000 of the Company's common units. During 2018, the Company purchased 1,274,161 common units for an aggregate price of approximately $21,202.

Revenue

Revenue in 2018 increased $212,587, or 15.5%, as compared to 2017. Excluding growth from acquisitions of 5.2% and the favorable impact from changes in foreign exchange rates of 0.5%, partially offset by the effect of a decrease in average silver prices in the Diversified Industrial segment of 0.4%, revenue increased by 10.2%. The net revenue increase of 10.2% was due to increases across all of our segments. The acquisition growth was primarily due to the acquisitions of Dunmore (February 2018) and Basin (May 2017).

Cost of Goods Sold

Cost of goods sold in 2018 increased $151,488, or 15.8%, as compared to 2017 primarily due to increases in the Diversified Industrial and Energy segments. The increase in the Diversified Industrial segment was primarily due to higher sales volume and the Dunmore acquisition. The increase in the Energy segment was due to the overall revenue increase and the Basin acquisition.

Selling, General and Administrative Expenses

Selling, general and administrative expenses ("SG&A") in 2018 increased $15,075, or 4.5%, as compared to 2017, primarily due to increases in the Diversified Industrial, Energy and Financial Services segments, partially offset by a decrease in the Corporate and Other segment. Excluding the Dunmore acquisition impact, the increase in the Diversified Industrial segment was primarily due to higher sales volume and costs incurred to consolidate certain operations, including footprint consolidation. The increase in the Energy segment was primarily due to higher sales volume and the Basin acquisition. The increase in the Financial Services segment was due to higher personnel expenses to support growth initiatives and increasing regulatory compliance. The decrease in the Corporate and Other segment was primarily due to the non-cash incentive unit expense of approximately $9,021 recorded in

21

2017, partially offset by a legal settlement recorded and higher professional fees in 2018. There was no incentive unit expense recorded in 2018.

Asset Impairment Charges

The asset impairment charges of $8,108 in 2018 were primarily associated with the loss of acquired customer relationships in the Company's Packaging business in its Diversified Industrial segment. In 2017, the Company recorded a non-cash impairment charge of $2,028 in its Energy segment related to an other-than-temporary impairment of a certain investment.

Interest Expense

Interest expense for the years ended December 31, 2018 and 2017 was $39,234 and $22,804, respectively. The higher interest expense in 2018 was primarily due to higher borrowing levels due to the Company's recent acquisitions and interest on SPLP's preferred units, which are classified as liabilities and issued primarily in 2017, as well as higher interest rates.

Realized and Unrealized Losses (Gains) on Securities, Net

Realized and unrealized losses (gains) on securities, net was a loss of $62,586 in 2018, as compared to a gain of $790 in 2017. The amounts are not comparable due to the required adoption of a new accounting standard, ASU 2016-01, on January 1, 2018 that requires equity investments, other than those accounted for under the traditional equity method of accounting, to be measured at their fair value with changes in fair value recognized in the consolidated statements of operations. The 2018 loss was principally driven by an unrealized loss on the Company's investment in BW shares. Prior to January 1, 2018, changes in fair value were reported in Accumulated other comprehensive income or loss on the consolidated balance sheets.

All Other Expenses, Net

All other expenses, net was unfavorable by $9,983 in 2018, as compared to 2017, primarily due to higher finance interest expense and higher provision for loan losses recorded in 2018 in the Financial Service segment, partially offset by higher income from investments and derivatives recorded in 2018, as compared to 2017.

Income Taxes

As a limited partnership, we are generally not responsible for federal and state income taxes, and our profits and losses are passed directly to our limited partners for inclusion in their respective income tax returns. The Company's tax provision represents the income tax expense or benefit of its consolidated corporate subsidiaries. For the year ended December 31, 2018, a tax provision of $12,559 was recorded, as compared to $51,299 in 2017. The Company recorded an income tax provision of approximately $58,717 in 2017 resulting from the one-time mandatory repatriation tax and the revaluation of our U.S. deferred tax assets and liabilities to reflect the 21% federal corporate tax rate enacted under the Act in December 2017. The Company recomputed its repatriation tax in 2018 and recorded an income tax benefit of $1,896 to reflect its revised estimate. However, significant losses incurred by a corporate subsidiary together with losses incurred by the limited partnership, a flow-through entity, for both of which no tax benefits have been recorded, resulted in a negative effective tax rate of 133.3% based on the consolidated loss before income taxes and equity method investments of $9,422 in 2018.

Loss (Income) of Associated Companies, Net of Taxes

The Company incurred a loss from associated companies, net of taxes of $9,509 in 2018, as compared to a gain of $16,888 in 2017. The year-over-year change is primarily due to unrealized mark-to-market adjustments for equity method investments that are accounted for using the fair value option. For the details of each of these investments and the related mark-to-market adjustments in both periods, see Note 10 - "Investments" to the SPLP consolidated financial statements found elsewhere in this Form 10-K.

Diversified Industrial

Net sales in 2018 increased by $130,478, or 11.3%, as compared to 2017. The change in net sales reflects $64,501 in incremental sales associated with the Dunmore and PST (June 2018) acquisitions and the favorable impact from foreign exchange rates of $6,264, partially offset by a decrease of $5,648 as a result of lower average silver prices. Excluding the acquisitions, foreign exchange rate impact and change in silver prices, net sales increased by approximately $65,361 due to increased demand across all of our businesses in the segment, except for the Packaging business in 2018, as compared to 2017. The incremental revenue from 2018 was primarily driven by higher demand for our private label roofing products from the commercial roofing sector, and electrical products from the military and aerospace sectors, as well as the favorable impact from higher oil & gas prices.

Segment operating income in 2018 decreased by $7,443, or 14.9%, as compared to 2017, primarily due to the non-cash asset impairment charge in the Packaging business and costs incurred to consolidate certain operations. Excluding the Dunmore and PST acquisition impact, gross profit increased in the segment as a result of higher sales volume, and SG&A was higher, driven by higher sales volume and costs incurred to consolidate certain operations in our Packaging and Electrical Products businesses.

Energy

In 2018, net revenue increased $40,489, or 29.9%, as compared to 2017. The increase in net revenue, which includes incremental sales of approximately $6,447 from the Basin acquisition in May 2017, reflects an overall increase in the Company's energy business as the demand for services continued to improve in line with the increase in the North American oil & gas drilling rig count.

Segment operating loss in 2018 decreased $15,172, or 70.5%, as compared to 2017. The reduction in operating loss was primarily due to higher gross profit, partially offset by higher SG&A due to the higher sales volume and a loss from associated companies, which are principally valued using the fair value option. The increase in gross profit was primarily the result of the increase in net revenue recorded in 2018, as compared to 2017.

Financial Services

Revenue in 2018 increased $41,620, or 51.8%, as compared to 2017. The increase was due to higher interest income driven by larger outstanding loan receivable balances and increased volume in lending programs, as compared to 2017.

23

Segment operating income in 2018 increased $13,216, or 32.0%, as compared to 2017. The increase was due to the impact of the higher revenue discussed above, partially offset by higher SG&A, driven by higher personnel expenses to support growth initiatives and the continued expansion of WebBank's compliance and oversight group to meet increasing regulatory expectations. In addition, the provision for loan losses increased $13,419 and finance interest expense increased $5,603 in 2018, as compared to 2017. The higher provision for loan losses was to support growth of consumer and small business loans held to maturity, and the higher finance interest expense was due to a larger deposit balance to support loan growth and an increase in interest rates.

Net Interest Income, Margin and Interest Rate Spreads

Net interest income is the difference between interest earned on interest-earning assets and interest incurred on interest-bearing liabilities. By its nature, net interest income is especially vulnerable to changes in the mix and amounts of interest-earning assets and interest-bearing liabilities. In addition, changes in the interest rates and yields associated with these assets and liabilities can significantly impact net interest income. The following table summarizes the average balances, the amount of interest earned or incurred and the applicable yields for interest-earning assets and the costs of interest-bearing liabilities that generate net interest income. For purposes of calculating the yields in these schedules, the average loan balances also include the principal amounts of nonaccrual and restructured loans. However, interest received on nonaccrual loans is included in income only to the extent that cash payments have been received and not applied to principal reductions. In addition, interest on restructured loans is generally accrued at reduced rates.

WebBank has several lending arrangements with companies where it originates credit card and other loans for consumers and small businesses. These loans are classified as held for sale and are typically sold after origination.

The following table presents the effects of changing rates and volumes on WebBank's net interest income for the periods indicated. The rate column shows the effects attributable to changes in rate (changes in rate multiplied by prior volume). The volume column shows the effects attributable to changes in volume (changes in volume multiplied by prior rate). The total column represents the sum of the prior columns. For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately, based on the changes due to rate and the changes due to volume.

Summary of Loan Loss Experience

The methodologies used to estimate the allowance for loan losses ("ALLL") depend upon the impairment status and portfolio segment of the loan. Loan groupings are created for each loan class and are then graded against historical and industry loss rates. After applying historic loss experience, as described above, we review the quantitatively derived level of ALLL for each segment using qualitative criteria. We track various risk factors that influence our judgment regarding the level of the ALLL across the portfolio segments. The following table summarizes activity in WebBank's allowance for loan and lease losses for the periods indicated:

Corporate and Other

Segment operating loss increased $97,187 in 2018, as compared to 2017, as a result of higher losses in 2018 driven by unrealized losses on equity investments, which are recorded in earnings since the adoption of ASU 2016-01 on January 1, 2018, as well as higher interest expense, primarily due to interest expense recorded on the SPLP preferred units issued in 2017, partially offset by lower SG&A and higher other income. The lower SG&A was primarily due to non-cash incentive unit expense of approximately $9,021 recorded in 2017, partially offset by a legal settlement recorded and higher professional fees in 2018. There was no incentive unit expense recorded in 2018.

For additional information on the adoption of ASU 2016-01, see Note 2 - "Summary of Significant Accounting Policies" and Note 10 - "Investments" to the SPLP consolidated financial statements found elsewhere in this Form 10-K.

DISCUSSION OF CONSOLIDATED CASH FLOWS

Net loss of $31,490 was impacted by certain non-cash items and a net unfavorable change of $88,843 relating to certain operating assets and liabilities. The net change in operating assets and liabilities was primarily due to an increase of $51,370 in loans held for sale due to the timing of loan originations, which can vary significantly from period-to-period since these loans are typically sold after origination, as well as the level of activity at WebBank, an increase of $19,625 in trade and other receivables due to timing of receipts, an increase in inventories of $7,415 to support sales growth in the Diversified Industrial segment, and an increase in prepaid expenses and other assets of $7,851.

Net cash used in operating activities for the year ended December 31, 2017 was $15,770. Net income of $6,012 was impacted by certain non-cash items and a net unfavorable change of $132,576 relating to certain operating assets and liabilities. The net change in operating assets and liabilities was primarily due to an increase of $56,081 in loans held for sale due to the timing of loan originations, which can vary significantly from period-to-period since these loans are typically sold after origination, as well as the level of activity at WebBank, an increase of $22,842 in trade and other receivables due to timing of receipts, an increase in inventories of $21,683 to support sales growth in the Diversified Industrial segment, a decrease in prepaid expenses and other assets of $4,281, a decrease of $36,251 in accounts payable, accrued and other liabilities due primarily to higher pension contributions and timing of payments.

Net cash provided by financing activities for the year ended December 31, 2018 was $226,621, including net revolver borrowings of $65,315 and a net increase in WebBank's deposits of $200,311. These increases were partially offset by cash used to purchase the Company's common units of $21,202 and $18,068 used to purchase subsidiary shares from noncontrolling interests, primarily the acquisition of WFHC shares.

Net cash provided by financing activities for the year ended December 31, 2017 was $155,889, including net revolver borrowings of $67,864 and a net increase in WebBank's deposits of $145,395. These increases were partially offset by domestic term loan repayments of $47,993, cash used to purchase the Company's common units of $5,188, as well as payment of financing-related fees of $5,663.

LIQUIDITY AND CAPITAL RESOURCES

SPLP (excluding its operating subsidiaries, "Holding Company") is a diversified global holding company with assets that principally consist of the stock of its direct subsidiaries, equity method and other investments, and cash and cash equivalents. The Company works with its businesses to enhance the liquidity and operations of its businesses and increase long-term value for its unitholders and stakeholders through balance sheet improvements, capital allocation policies, and operational and growth initiatives, which are further described in Item 1 - "Business - Business Strategy."

On January 31, 2019, the Company entered into an amendment to its senior secured revolving credit facility ("Credit Agreement") to increase the Company's borrowing capacity. The Credit Agreement covers substantially all of the Company's subsidiaries, with the exception of WebBank. Availability under the Credit Agreement is based upon earnings and certain covenants, including a maximum ratio limit on Total Leverage and a minimum ratio limit on Interest Coverage, as defined in the Credit Agreement. The amendment increased the allowable leverage by 0.25 "turns" on a permanent basis through the maturity of the Credit Agreement and converted $200,000 of the revolving credit commitments into a term loan with quarterly amortization equating to 5.0% per annum, resulting in a $500,000 revolving credit facility going forward. The Credit Agreement is subject to certain mandatory prepayment provisions and restrictive and financial covenants, primarily the leverage ratios described above. The Company was in compliance with all financial covenants at December 31, 2018. There can be no assurances that the Company will continue to have access to this line of credit if its financial performance does not satisfy the financial covenants set forth in the Credit Agreement. If the Company does not meet its financial covenants, and if it is unable to secure necessary waivers or other amendments from its lenders on terms acceptable to management, its ability to access available lines of credit could be limited, its debt obligations could be accelerated and liquidity could be adversely affected. The Credit Agreement will expire, with all amounts outstanding due and payable, on November 14, 2022.

The Holding Company and its operating businesses believe that they have access to adequate resources to meet their needs for normal operating costs, capital expenditures, pension payments, debt obligations and working capital for their existing business for at least the next twelve months. These resources include cash and cash equivalents, investments, cash provided by operating activities and unused lines of credit. The Holding Company and its operating businesses' ability to satisfy their debt service obligations, to fund planned capital expenditures and required pension payments, and to make acquisitions or repurchase units under its common unit Repurchase Program will depend upon their future operating performance, which will be affected by prevailing economic conditions in the markets in which they operate, as well as financial, business and other factors, some of which are beyond their control. As indicated above, there can be no assurances that the Holding Company and its operating businesses will continue to have access to their lines of credit if their financial performance does not satisfy the financial covenants set forth in their respective financing agreements, which could also result in the acceleration of their debt obligations by their respective lenders, adversely affecting liquidity.

Management is utilizing the following strategies to continue to enhance liquidity: (1) continuing to implement improvements using the Steel Business System throughout all the Company's operations to increase sales and operating efficiencies, (2) supporting profitable sales growth both internally and potentially through acquisitions and (3) evaluating from time to time and as appropriate, strategic alternatives with respect to its businesses and/or assets. The Company continues to examine all of its options and strategies, including acquisitions, divestitures and other corporate transactions, to increase cash flow and stakeholder value.

As of December 31, 2018, the Company's working capital was $422,374, as compared to working capital of $513,689 as of December 31, 2017. As of December 31, 2018, the availability under the Credit Agreement was approximately $42,900. During the years ended December 31, 2018 and 2017, capital expenditures were $47,085 and $54,737, respectively. The Company currently expects full year capital expenditures in the range of $41,000 to $52,000 in 2019. The Company and its subsidiaries have ongoing commitments as noted in the table below. These commitments include funding of the minimum requirements of its subsidiaries' pension plans. Required future pension contributions are estimated based upon assumptions such as discount rates

28

on future obligations, assumed rates of return on plan assets and legislative changes. Actual future pension costs and required funding obligations will be affected by changes in the factors and assumptions described in the previous sentence, as well as other changes such as any plan termination or other acceleration events.

WebBank manages its liquidity to provide adequate funds to meet anticipated financial obligations, such as certificate of deposit maturities and to fund customer credit needs. WebBank had $242,088 and $286,454 in cash at the Federal Reserve Bank and in its Federal Funds account at its correspondent banks at December 31, 2018 and 2017, respectively. WebBank had $35,000 and $30,000 in lines of credit from its correspondent banks at December 31, 2018 and 2017, respectively. WebBank had $71,345 and $59,514 available from the Federal Reserve discount window at December 31, 2018 and 2017, respectively. WebBank had a total of $348,433 and $375,968 in cash, lines of credit and access to the Federal Reserve Bank discount window at December 31, 2018 and 2017, respectively, which represents approximately 40.0% and 59.8%, respectively, of WebBank's total assets.

Contractual Commitments and Contingencies

Our consolidated contractual obligations as of December 31, 2018 are identified in the table below:

	Payments Due By Period
	Less Than 1 Year		1 - 3 Years		3 - 5 Years		Thereafter		Total
Debt obligations (a)	$	3,893	$	4,529	$	473,567	$	—	$	481,989
Estimated interest expense (a), (b)	23,985		47,446		21,653		—		93,084
Deposits (c)	431,959		279,352		—		—		711,311
Operating lease obligations	14,280		20,106		10,037		17,867		62,290
Capital lease obligations	1,419		2,466		2,280		681		6,846
Minimum pension contributions (d)	34,287		70,474		66,826		23,700		195,287
Preferred unit liability (e)	—		40,000		—		—		40,000
Total	$	509,823	$	464,373	$	574,363	$	42,248	$	1,590,807

(a) Assumes repayment of the $472,495 balance outstanding on the Credit Agreement as of December 31, 2018 on its November 14, 2022 contractual maturity date. The outstanding balance on SPLP's Credit Agreement will fluctuate before maturity, and the repayment dates and amounts may differ. The January 2019 amendment to the Company's Credit Agreement will add the following principal repayment requirements, which are not reflected in the table above: $7,500 in 2019 and $10,000 in each of 2020, 2021 and 2022.

(b) Estimated interest expense does not include non-cash amortization of debt issuance costs, which is included in interest expense in the Company's consolidated financial statements. The interest rates used to estimate future interest expense were based on interest rates at December 31, 2018. As the majority of the Company's long-term debt bears interest at variable rates, any future interest rate fluctuations will impact future cash payments.

(c) Excludes interest. The average interest rate on deposits at December 31, 2018 was 2.23% and interest rates ranged from 0.00% to 3.23%.

(d) Represents total expected required minimum pension plan contributions to the Company's significant pension plans for 2019, 2020, 2021, 2022, 2023 and for the five years thereafter. Actual future pension costs and required funding obligations will be affected by changes in the factors and assumptions described elsewhere in this Annual Report on Form 10-K, as well as other changes such as any plan termination or other acceleration events. The Company's other pension and post-retirement obligations are not significant individually or in the aggregate.

(e) Represents redemption of 1,600,000 6.0% Series A preferred units, no par value, on the third anniversary of the original issuance date of the SPLP preferred units (February 7, 2020) at a redemption price equal to the liquidation preference value of $25 per unit, in cash. In addition to the amount in the table above, the Partnership Agreement also specifies that if the SPLP preferred units are not redeemed earlier, then on the ninth anniversary of the original issuance date (February 7, 2026), the remaining SPLP preferred units will be redeemed. The redemption price will be $25 per unit in cash or in common units or a combination thereof, at the sole discretion of the Company's Board of Directors. Upon redemption, the holders of the SPLP preferred units will also receive any accumulated and unpaid distributions as of the redemption date. The SPLP preferred units entitle the holders to a cumulative quarterly cash or in-kind (or a combination thereof) distribution, if and when declared at the discretion of the Company's Board of Directors.

Environmental Liabilities

Certain of the Company's facilities are subject to environmental remediation obligations. The Company has estimated its liability to remediate these sites and has recorded $14,960 at December 31, 2018. For further discussion regarding these commitments, among others, see Note 19 - "Commitments and Contingencies" to the Company's consolidated financial statements found elsewhere in this Form 10-K.

Deposits

Deposits at WebBank at December 31, 2018 and 2017 were as follows:

29

	2018		2017
Current	$	431,959	$	305,207
Long-term	279,352		205,793
Total	$	711,311	$	511,000

The increase in deposits at December 31, 2018, as compared to 2017, is due to WebBank's asset growth. The average original maturity for time deposits at December 31, 2018 was 23 months, as compared to 27 months at December 31, 2017.

The following table details the maturity of time deposits as of December 31, 2018:

	Maturity

Certificate of deposits less than $100	$	55,000	$	83,009	$	147,750	$	279,352	$	565,111
Certificate of deposits of $100 or more	6,288		4,656		13,874		—		24,818
Total certificates of deposits	$	61,288	$	87,665	$	161,624	$	279,352	$	589,929

Off-Balance Sheet Risk

It is not the Company's usual business practice to enter into off-balance sheet arrangements such as guarantees on loans and financial commitments, indemnification arrangements and retained interests in assets transferred to an unconsolidated entity for securitization purposes. SPLP uses the same credit policy in making commitments and conditional obligations as it does for on-balance sheet instruments.

WebBank is a party to financial instruments with off-balance sheet risk. In the normal course of business, these financial instruments include commitments to extend credit in the form of loans as part of WebBank's lending arrangements with Marketing Partners. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the Company's consolidated balance sheets. The contractual amounts of those instruments reflect the extent of involvement WebBank has in particular classes of financial instruments.

At December 31, 2018 and 2017, WebBank's undisbursed commitments under these instruments totaled $130,697 and $148,529, respectively. Commitments to extend credit are agreements to lend to a borrower who meets the lending criteria established by WebBank through one of WebBank's lending agreements with Marketing Partners, provided there is no violation of any condition established in the contract with the counterparty to the lending arrangement. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee, and in some cases are subject to ongoing adjustment by WebBank. Since certain of the commitments are expected to expire without the credit being extended, the total commitment amounts do not necessarily represent future cash requirements. WebBank evaluates each prospective borrower's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by WebBank upon extension of credit, is based on management's credit evaluation of the borrower and WebBank's Marketing Partner.

WebBank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. WebBank uses the same credit policy in making commitments and conditional obligations as it does for on-balance sheet instruments.

Critical Accounting Policies

The Company's discussion and analysis of financial condition and results of operations is based upon its consolidated financial statements, which have been prepared in conformity with U.S. GAAP. Preparation of these consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosure of contingent assets and liabilities. Estimates are based on historical experience, expected future cash flows and various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates.

Note 2 - "Summary of Significant Accounting Policies"to the Company's consolidated financial statements, included elsewhere in this Annual Report on Form 10-K, includes a summary of the significant accounting policies and methods used in the preparation of the consolidated financial statements. The following is a discussion of the critical accounting policies and methods used by the Company.

30

Goodwill and Other Intangible Assets, Net

Goodwill, which is not amortized, represents the difference between the purchase price and the fair value of identifiable net assets acquired in a business combination. We review goodwill for impairment annually in the fourth quarter, and test for impairment during the year if an event occurs or circumstances change that would indicate the carrying amount may be impaired. Examples of such events would include pertinent macroeconomic conditions, industry and market considerations, overall financial performance and other factors. An entity can choose between using the Step 0 approach or the Step 1 approach.

For the Step 0 approach, an entity may assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity has an unconditional option to bypass the Step 0 assessment for any reporting unit in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the Step 0 assessment in any subsequent period.

For the Step 1 approach, which is a quantitative approach, the Company will calculate the fair value of a reporting unit and compare it to its carrying amount. There are several methods that may be used to estimate a reporting unit's fair value, including the income approach, the market approach and/or the cost approach. If the fair value of a reporting unit exceeds its carrying amount, there is no indication of impairment and further testing is not required. If the carrying amount of a reporting unit exceeds its fair value, then a second step of testing is required. The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill.

For 2018, the Company utilized the Step 0 approach for all of its reporting units, except for the Packaging business within its Diversified Industrial segment. Based on its qualitative assessment, the Company does not believe that it is more likely than not that the fair value of any of its reporting units tested under this approach is less than its carrying value. The Company performed a quantitative assessment of goodwill associated with its Packaging business due to a decline in market conditions and lower demand for certain of the Packaging business' product lines. The assessment was based on a combination of income and market approaches to estimate the fair value of the reporting unit, which indicated that the fair value of this reporting unit exceeded its carrying value by approximately 21.9%. The carrying value and goodwill associated with the Packaging business were approximately $160,951 and $40,827, respectively, at December 31, 2018. Significant assumptions used in the discounted cash flow analysis included expected future earnings and cash flows, which are based on management's current expectations, as well as the related risk-adjusted discount rate used to estimate fair value. At December 31, 2018, the goodwill related to the Packaging business, and associated intangible assets, are at risk of future impairment if the fair value of this reporting unit, and its associated assets, decrease in value due to further declines in market conditions or customer demand.

For 2017, the Company utilized the Step 0 approach for all of its reporting units to assess goodwill, and there were no goodwill impairment charges recorded as a result of the assessment.

For definite-lived intangible assets, the Company evaluates the carrying value of such assets when circumstances indicate the carrying amount may not be recoverable. Conditions that could have an adverse impact on the cash flows and fair value of the long-lived assets are deteriorating business climate, condition of the asset or plans to dispose of the asset before the end of its useful life. If the assets' carrying values exceed the sum of the undiscounted cash flows, an impairment charge is recognized in the amount by which the carrying values exceeds their fair values. The Company performs such assessments at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities, which is generally at the plant level, operating company level or the reporting unit level, depending on the level of interdependencies in the Company's operations. During 2018, the Company recorded non-cash impairment charges totaling approximately $7,600, calculated using the income approach, primarily associated with the loss of acquired customer relationships in the Company's Packaging business.

Intangible assets with indefinite lives, which are only within the Diversified Industrial segment, are tested for impairment at least annually, or when events or changes in circumstances indicate that it is more likely than not that the asset is impaired. Companies can use the same two testing approaches for indefinite-lived intangibles as for goodwill. For 2018 and 2017, the Company utilized the Step 0 approach to assess its intangible assets with indefinite lives as of December 31, and the results indicated no impairment in either of these years.

Pension and Other Post-Retirement Benefit Costs

Some of the Company's subsidiaries maintain qualified and non-qualified pension and other post-retirement benefit plans. The Company recorded pension expense of $3,184 for the year ended December 31, 2018 related to its significant pension plans, and, at December 31, 2018, the Company had recorded pension liabilities totaling $205,770. Pension benefits are generally based on years of service and the amount of compensation earned during the participants' employment. However, the qualified pension benefits have been frozen for all participants.

31

The pension and other post-retirement benefit costs are developed from actuarial valuations. Inherent in these valuations are key assumptions, including discount and mortality rates and expected long-term rates of return on plan assets. Material changes in pension and other post-retirement benefit costs may occur in the future due to changes in these assumptions, changes in the number of plan participants, changes in the level of benefits provided, changes to the level of contributions to these plans and other factors.

Actuarial assumptions for its pension and other post-retirement benefit plans are determined each year to calculate liability information as of December 31, and pension and other post-retirement benefit expense or income for the following year. The discount rate assumption is derived from the rate of return on high-quality bonds.

The various pension plan assets are diversified as to type of assets, investment strategies employed and number of investment managers used. Investments may include equities, fixed income, cash equivalents, convertible securities and private investment funds. Derivatives may be used as part of the investment strategy. The transfer of assets may be directed between investment managers in order to rebalance the portfolio in accordance with asset allocation guidelines established by the Company. The private investment funds, or the investment funds they are invested in, own marketable and non-marketable securities and other investment instruments. Such investments are valued by the private investment funds, underlying investment managers or the underlying investment funds at fair value, as described in their respective financial statements and offering memorandums. These values are utilized in quantifying the value of the assets of its pension plans, which are then used in the determination of the unfunded pension liabilities on the Company's consolidated balance sheets. Because of the inherent uncertainty of valuation of some of the pension plans' investments in private investment funds and the nature of some of the underlying investments held by the investment funds, the recorded value may differ from the value that would have been used had a ready market existed for some of these investments for which market quotations are not readily available. Management uses judgment to make assumptions on which its employee benefit liabilities and expenses are based. The effect of a 1% change in discount rate or expected return on asset assumptions for the pension plans sponsored by the Company's subsidiaries would not be material to the Company.

Loan Impairment and Allowance for Loan Losses

A loan is considered impaired when, based on current information and events, it is probable that WebBank will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments. When a loan has been identified as being impaired, the amount of impairment is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, when appropriate, the loan's observable fair value or the fair value of the collateral (less any selling costs) if the loan is collateral-dependent. If the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest, net of deferred loan fees or costs and unamortized premium or discount), an impairment is recognized by creating or adjusting an existing allocation of the ALLL, or by charging down the loan to its value determined in accordance with U.S. GAAP.

The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when the uncollectability of a loan or receivable balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The ALLL is evaluated on a regular basis and is based upon a periodic review of the collectability of the amounts due in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are classified as doubtful, substandard or loss. For such loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical loss experience and is adjusted for qualitative factors to cover uncertainties that could affect the estimate of probable losses. The ALLL is increased by charges to income and decreased by charge-offs (net of recoveries). The periodic evaluation of the adequacy of the allowance is based on WebBank's past loss experience, known and inherent risks in the portfolio, adverse situations that may affect the debtor's ability to repay, the estimated value of any underlying collateral and current economic conditions. Since our loss rates are applied to large pools of loans, even minor changes in the level of estimated losses can significantly affect management's determination of the appropriate ALLL because those changes must be applied across a large portfolio.

Income Taxes

As a limited partnership, we are generally not responsible for federal and state income taxes, and our profits and losses are passed directly to our limited partners for inclusion in their respective income tax returns. Our subsidiaries that are corporate subsidiaries are subject to federal and state income taxes. The table in Note 16 - "Income Taxes" to the SPLP consolidated financial

32

statements, found elsewhere in this Form 10-K, reconciles a hypothetical calculation of federal income taxes based on the federal statutory rate applied to the income or loss before income taxes and equity method investments. The tax effect of income passed through to common unitholders is subtracted from the hypothetical calculation.

Our subsidiaries that are subject to income taxes use the liability method of accounting for such taxes. Under the liability method, deferred tax assets and deferred tax liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and deferred tax liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and deferred tax liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Our subsidiaries evaluate the recoverability of deferred tax assets and establish a valuation allowance when it is more likely than not that some portion of the deferred tax assets will not be realized.

When tax returns are filed, it is highly certain that most positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the consolidated financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50% likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is provided for and reflected as a liability for unrecognized tax benefits on the consolidated balance sheets, along with any associated interest and penalties that would be payable to the taxing authorities upon examination.

Environmental Remediation

The facilities and operations of the Company's subsidiaries are subject to extensive environmental laws and regulations imposed by federal, state, foreign and local authorities relating to the protection of the environment. Accruals for losses associated with environmental remediation obligations are recorded when such losses are probable and reasonably estimable, which is a critical accounting estimate. Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study. Such accruals are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable. Reserves may not be adequate to cover the ultimate costs of remediation, including discovery of additional contaminants or the imposition of additional cleanup obligations, which could result in significant additional costs, unfavorably impacting the Company's financial position and results of operations.

New or Recently Adopted Accounting Pronouncements

For a discussion of the Company's new or recently adopted accounting pronouncements, see Note 2 - "Summary of Significant Accounting Policies" to the SPLP consolidated financial statements found elsewhere in this Form 10-K.

Item 7A. Quantitative and Qualitative Disclosures About Market Risk

In this "Quantitative and Qualitative Disclosure About Market Risk" section, all dollar amounts are in thousands.

Market risk is the risk of loss arising from adverse changes in market rates and prices, such as interest rates, foreign currency exchange rates and commodity prices. Our significant market risks are primarily associated with interest rates, equity prices and, to a lesser extent, derivatives. The following sections address the significant market risks associated with our business activities.

SPLP's quantitative and qualitative disclosures about market risk include forward-looking statements with respect to management's opinion about the risk associated with the Company's financial instruments. These statements are based on certain assumptions with respect to market prices, interest rates and other industry-specific risk factors. To the extent these assumptions prove to be inaccurate, future outcomes may differ materially from those discussed herein.

Risks Relating to Investments

The Company's investments are primarily classified as Marketable securities or Long-term investments and are primarily recorded on the Company's consolidated balance sheets at fair value. These investments are subject to equity price risk.

33

At December 31, 2018, Marketable securities aggregated approximately $1,439, which includes mutual funds and corporate equities that are reported at fair value. In addition, financial instrument obligations aggregated $12,434 at December 31, 2018. A change in the equity price of these securities could impact our results in future periods.

Included in the Company's Long-term investments of $258,044 at December 31, 2018 are equity securities and associated company investments, which are both subject to equity price risk. The Company's significant associated company investments as of December 31, 2018 include its investments in STCN and Aviat Networks, Inc. The Company's investments in associated companies are accounted for under the equity method of accounting, primarily using the fair value option. A change in the equity price of our investments in these securities could impact our results in future periods.

See Note 10 - "Investments" to the SPLP consolidated financial statements found elsewhere in this Form 10-K for more information about the Company's marketable securities and associated company investments.

Risks Relating to Interest Rates

The fair value of cash and cash equivalents, trade and other receivables, accounts payable and short-term borrowings approximate their carrying values and are relatively insensitive to changes in interest rates due to the short-term maturities of these instruments or the variable nature of the associated interest rates.

Credit Facilities and Pension Obligations

At December 31, 2018, the Company's long-term debt obligations were comprised primarily of variable rate instruments. Accordingly, the fair value of such instruments may be relatively sensitive to effects of interest rate fluctuations. An increase or decrease in interest expense from a 1% change in interest rates would be approximately $4,800 on an annual basis based on total variable-interest debt outstanding as of December 31, 2018. In addition, the fair value of such instruments is also affected by investors' assessments of the risks associated with industries in which the Company operates, as well as its overall creditworthiness and ability to satisfy such obligations upon their maturity.

A reduction in long-term interest rates could materially increase the Company's cash funding obligations to its pension and other post-retirement benefit plans.

WebBank

WebBank derives a portion of its income from the excess of interest collected over interest paid. The rates of interest WebBank earns on assets and pays on liabilities generally are established contractually for a period of time. Market interest rates change over time. Accordingly, WebBank's results of operations, like those of most financial institutions, are impacted by changes in interest rates and the interest rate sensitivity of its assets and liabilities.

WebBank monitors and measures its exposure to changes in interest rates in order to comply with applicable government regulations and risk policies established by WebBank's board of directors and in order to preserve shareholder value. In monitoring interest rate risk, WebBank analyzes assets and liabilities based on characteristics including size, coupon rate, repricing frequency, maturity date and likelihood of prepayment.

WebBank currently focuses held-to-maturity lending efforts toward originating competitively priced adjustable-rate or fixed-rate loan products with short to intermediate terms to maturity, generally 7 years or less. This theoretically allows WebBank to maintain a portfolio of loans that will have relatively little sensitivity to changes in the level of interest rates, while providing a reasonable spread over the cost of liabilities used to fund the loans.

The principal objective of WebBank's asset/liability management is to manage the sensitivity of Market Value of Equity ("MVE") to changing interest rates. Asset/liability management is governed by policies reviewed and approved annually by WebBank's board of directors. WebBank's board of directors has delegated the responsibility to oversee the administration of these policies to WebBank's asset/liability committee, or "ALCO." The interest rate risk strategy currently deployed by ALCO is to primarily use "natural" balance sheet hedging (as opposed to derivative hedging). ALCO fine tunes the overall MVE sensitivity by recommending lending and deposit strategies. WebBank then executes the recommended strategy by increasing or decreasing the duration of the loan and deposit products, resulting in the appropriate level of market risk that WebBank's board of directors wants to maintain.

34

WebBank measures interest rate sensitivity as the difference between amounts of interest earning assets and interest bearing liabilities that mature or reprice within a given period of time. The difference provides an indication of the extent to which an institution's interest rate spread will be affected by changes in interest rates. If the amount of interest rate sensitive assets exceeds the amount of interest rate sensitive liabilities, then the bank is considered to be asset sensitive. If the amount of interest rate sensitive liabilities exceeds the amount of interest rate sensitive assets, then the bank is considered to be liability sensitive. In a rising interest rate environment, an institution that is asset sensitive would be in a better position than an institution that is liability sensitive because the yield on its assets would increase at a faster pace than the cost of its interest bearing liabilities. During a period of falling interest rates, however, an institution that is asset sensitive would tend to have its assets reprice at a faster rate than its liabilities, which would tend to reduce the growth in its net interest income. The opposite is true if the institution is liability sensitive.

WebBank's board of directors and relevant government regulations establish limits on the level of acceptable interest rate risk at WebBank to which management adheres. There can be no assurance, however, that, in the event of an adverse change in interest rates, WebBank's efforts to limit interest rate risk will be successful.

Risks Relating to Commodity Prices

In the normal course of business, our operations are exposed to market risk or price fluctuations related to the purchase of electricity, natural gas, fuel and petroleum-based commodities, including adhesives, and other products, such as yarns, precious metals, electronic and electrical components, steel products and certain non-ferrous metals used as raw materials. The Company is also exposed to the effects of price fluctuations on the value of its commodity inventories, in particular, its precious metal inventory. The raw materials and energy which we use are largely commodities, subject to price volatility caused by changes in global supply and demand and governmental controls.

The Company's market risk strategy has generally been to obtain competitive prices for its products and services, sourced from more than one vendor, and allow operating results to reflect market price movements dictated by supply and demand. The Company enters into commodity futures and forward contracts to mitigate the impact of price fluctuations on its precious and certain non-precious metal inventories that are not subject to fixed price contracts. The Company's hedging strategy is designed to protect it against normal volatility; therefore, abnormal price changes in these commodities or markets could negatively impact the Company's earnings. Certain of these derivatives are not designated as accounting hedges under Accounting Standards Codification Subtopic 815-10, Derivatives and Hedging. As of December 31, 2018, the Company had entered into forward contracts, with settlement dates through January 2019, for silver with a total value of $3,993, for gold with a total value of $3,467, for palladium with a value of $951, for copper with a total value of $388 and for tin with a total value of $392. There were no futures contracts outstanding at December 31, 2018.

To the extent that we have not mitigated our exposure to rising raw material and energy prices, we may not be able to increase our prices to our customers to offset such potential raw material or energy price increases, which could have a material adverse effect on our results of operations and operating cash flows.

Risks Relating to Foreign Currency Exchange

The Company, primarily through its Diversified Industrial segment subsidiaries, manufactures and sells its products in a number of countries throughout the world and, as a result, is exposed to movements in foreign currency exchange rates. The Company's major foreign currency exposures involve the markets in Asia, Europe, Canada and Mexico. The Company is subject to the risk of price fluctuations related to anticipated revenues and operating costs, firm commitments for capital expenditures and existing assets or liabilities denominated in currencies other than the U.S. dollar. The Company has not generally used derivative instruments to manage these specific risks; however, the Company enters into foreign currency forward contracts to hedge certain of its receivables and payables denominated in other currencies, primarily those associated with its Packaging operations located in the United Kingdom. In addition, the Company enters into foreign currency forward contracts to hedge the value of certain of its future sales denominated in Euros and the value of certain of its future purchases denominated in U.S. dollars, also associated with its Packaging operations located in the United Kingdom.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the unitholders and the Board of Directors of Steel Partners Holdings L.P.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheet of Steel Partners Holdings L.P. and subsidiaries (the "Company") as of December 31, 2018, the related consolidated statements of operations, comprehensive (loss) income, changes in capital, and cash flows, for the year ended December 31, 2018, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018, and the results of its operations and its cash flows for the year ended December 31, 2018, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 28, 2019, expressed an unqualified opinion on the Company's internal control over financial reporting.

Change in Accounting Principle

As discussed in Note 2 to the consolidated financial statements, the Company has changed its method of accounting for available-for-sale equity securities, which are now reported at fair value, with unrealized gains and losses recognized in Realized and unrealized losses (gains) on securities, net in the consolidated statement of operations, with an opening balance cumulative effective reclassification adjustment from Accumulated other comprehensive loss to Partners' capital, in 2018, due to the adoption of Accounting Standards Update 2016-01-Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's consolidated financial statements based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audit 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 audit 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. We believe that our audit provides a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the unitholders and the Board of Directors of Steel Partners Holdings L.P.

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Steel Partners Holdings L.P. and subsidiaries(the "Company") as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2018, based on criteria established in Internal Control - Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheet of the Company as of December 31, 2018, the related consolidated statements of operations, comprehensive (loss) income, changes in capital, and cash flows, for the year ended December 31, 2018, and the related notes and our report dated February 28, 2019, expressed an unqualified opinion thereon.

As described in Management's Report on Internal Control Over Financial Reporting within Item 9A of this Form 10-K, management excluded from its assessment the internal control over financial reporting at Dunmore Corporation and Dunmore Europe GmbH (collectively, "Dunmore"), which were acquired on February 16, 2018 and whose financial statements constitute approximately 3.2% of the Company's total consolidated assets as of December 31, 2018 and approximately 3.8% of the Company's total consolidated revenue for the year then ended. Accordingly, our audit did not include the internal control over financial reporting at Dunmore.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying "Item 9A, Management's Report on Internal Control over Financial Reporting." Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

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 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

All amounts used in the Notes to Consolidated Financial Statements are in thousands, except common and preferred units, per common and preferred unit, share and per share data.

1. NATURE OF THE BUSINESS AND BASIS OF PRESENTATION

Nature of the Business

Steel Partners Holdings L.P. ("SPLP" or "Company") is a diversified global holding company that engages in multiple businesses through consolidated subsidiaries and other interests. It owns and operates businesses and has significant interests in companies in various industries, including diversified industrial products, energy, defense, supply chain management and logistics, banking and youth sports. SPLP operates through the following segments: Diversified Industrial, Energy, Financial Services, and Corporate and Other, which are managed separately and offer different products and services. For additional details related to the Company's reportable segments see Note 21 - "Segment Information." Steel Partners Holdings GP Inc. ("SPH GP"), a Delaware corporation, is the general partner of SPLP and is wholly-owned by SPLP. The Company is managed by SP General Services LLC ("Manager"), pursuant to the terms of an amended and restated management agreement ("Management Agreement") discussed in further detail in Note 20 - "Related Party Transactions."

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its majority or wholly-owned subsidiaries. All material inter-company accounts and transactions have been eliminated in consolidation. Certain amounts in the Company's 2017 consolidated statements of operations and cash flows have been reclassified to conform to the comparable 2018 presentation.

During the first quarter of 2018, the Company corrected an out-of-period misstatement related to the increase in the fair value of the Company's investment in Steel Connect, Inc. ("STCN") preferred stock for the period from December 15, 2017 to December 31, 2017. Had this correction been recorded at December 31, 2017, the Company's investment in STCN preferred stock would have increased to $46,208 at December 31, 2017, with a corresponding $11,208 increase in Income of associated companies, net of tax and Net income to $28,096 and $17,220, respectively. For the year ended December 31, 2018, the Company's Loss of associated companies, net of taxes and Net loss would have increased to losses of $20,717 and $42,698, respectively. In addition, the Company made a correction as of December 31, 2016, decreasing Accumulated other comprehensive loss by $1,782 and decreasing Partners' capital by the same amount, to properly reflect certain hedging activities associated with a 2015 business combination.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates in Preparation of Consolidated Financial Statements

The Company's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses, and related disclosure of contingent assets and liabilities during the reporting period. The more significant estimates include: (1) the valuation allowances for trade and other receivables, loans receivable and inventories; (2) the valuation of goodwill, indefinite-lived intangible assets, long-lived assets and associated companies; (3) deferred tax assets; (4) environmental liabilities; (5) fair value of derivatives; (6) post-employment benefit liabilities; (7) estimates and assumptions used in the determination of fair value of certain securities; and (8) estimates of loan losses. Actual results may differ from the estimates used in preparing the consolidated financial statements; and, due to substantial holdings in and/or restrictions on certain investments, the value that may be realized could differ from the estimated fair value.

Cash and Cash Equivalents

Cash and cash equivalents include cash and deposits in depository institutions, financial institutions and banks. Cash at December 31, 2018 and 2017 also includes $242,088 and $286,454, respectively, of WebBank cash at the Federal Reserve Bank and in its Federal Funds account at its correspondent banks. The Company considers all highly liquid debt instruments with maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include qualifying money market funds and exclude amounts where availability is restricted by loan agreements or other contractual provisions. Cash

45

equivalents are stated at cost, which approximates market value. There is a significant concentration of cash that, during the periods presented, exceeded the federal deposit insurance limits and exposed the Company to credit risk. SPLP does not anticipate any losses due to this concentration of cash at December 31, 2018.

Restricted Cash

Restricted cash at December 31, 2018 and 2017 primarily represents cash collateral for certain short sales of corporate securities (see Note 13 - "Financial Instruments" for additional information).

Marketable Securities and Long-Term Investments

Marketable securities consist of short-term deposits, corporate debt and equity instruments, and mutual funds. The Company classifies its marketable securities as current assets based on the nature of the securities and their availability for use in current operations. Long-term investments consist of equity securities and certain associated company investments. Held-to-maturity securities are classified in Other non-current assets. SPLP determines the appropriate classifications of its investments at the acquisition date and re-evaluates the classifications at each balance sheet date.

• Since the Company adopted Accounting Standards Update No. ("ASU") 2016-01 effective January 1, 2018, available-for-sale equity securities are now reported at fair value, with unrealized gains and losses recognized in Realized and unrealized losses (gains) on securities, net in the consolidated statement of operations. In 2017, prior to the adoption of ASU 2016-01, such unrealized gains and losses were recognized in Accumulated other comprehensive income (loss) ("AOCI") as a separate component of SPLP's Partners' capital.

• Available-for-sale debt securities are reported at fair value, with unrealized gains and losses recognized in AOCI as a separate component of SPLP's Partners' capital in both 2018 and 2017.

• Associated companies represent equity method investments in companies where our ownership is between 20% and 50% of the outstanding equity and the Company has the ability to exercise influence, but not control, over the investee. For equity method investments where the fair value option has been elected, unrealized gains and losses are reported in the Company's consolidated statements of operations as part of Loss (income) of associated companies, net of tax. For the equity method investments where the fair value option has not been elected, SPLP records the investment at cost and subsequently increases or decreases the investment by its proportionate share of the net income or loss and other comprehensive income or loss of the investee.

• Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts.

Dividend and interest income is recognized when earned. Realized gains and losses on marketable securities and long-term investments are included in earnings and are derived using the specific-identification method. Commission expense is recorded as a reduction of sales proceeds on investment sales. Commission expense on purchases is included in the cost of investments on the Company's consolidated balance sheets.

Other Than Temporary Impairment

If the Company believes a decline in the market value of any available-for-sale debt security, equity method or held-to-maturity security below cost is other than temporary, a loss is charged to earnings, which establishes a new cost basis for the security. Impairment losses are included in Asset impairment charges in the Company's consolidated statements of operations. SPLP's determination of whether a security is other than temporarily impaired incorporates both quantitative and qualitative information. The Company considers a number of factors including, but not limited to, the length of time and the extent to which the fair value has been less than cost, the length of time expected for recovery, the financial condition of the issuer, the reason for the decline in fair value, changes in fair value subsequent to the balance sheet date, the ability and intent to hold investments to maturity, and other factors specific to the individual investment.

Specifically, for held-to-maturity securities, the Company considers whether it plans to sell the security or it is more-likely-than-not that it will be required to sell the security before recovery of its amortized cost. The credit component of an other-than-temporary impairment loss is recognized in earnings and the non-credit component is recognized in AOCI in situations where the Company does not intend to sell the security and it is more likely-than-not that the Company will not be required to sell the security prior to recovery. If there is an other-than-temporary impairment in the fair value of any individual security classified as held-to-maturity, the Company writes down the security to fair value with a corresponding credit loss portion charged to earnings, and the non-credit portion being charged to AOCI. SPLP's assessment involves a high degree of judgment and accordingly, actual results may differ materially from those estimates and judgments.

46

Trade Receivables and Allowance for Doubtful Accounts

The Company recognizes bad debt expense through an allowance account using estimates based primarily on management's evaluation of the financial condition of the customer, historical experience, credit quality, whether any amounts are currently past due, the length of time accounts may be past due, previous loss history and management's determination of a customer's current ability to pay its obligations. Trade receivable balances are charged off against the allowance when it is determined that the receivables will not be recovered, and payments subsequently received on such receivables are credited to recovery of accounts written off. The Company believes that the credit risk with respect to trade receivables is limited due to this credit evaluation process. As of December 31, 2018, the top 10 of the Company's largest customer balances accounted for 20% of the Company's trade receivables.

Loans Receivable, Including Loans Held for Sale

WebBank's loan activities include several lending arrangements with companies where it originates credit card and other loans for consumers and small businesses. These loans are classified as Loans receivable and are typically sold after origination. As part of these arrangements, WebBank earns fees that are recorded in non-interest income. Fees earned from these lending arrangements are recorded as fee income. WebBank also purchases participations in commercial and industrial loans through loan syndications. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses ("ALLL"), and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield over the estimated life of the loan.

Through a loan program, merchants can borrow a certain percentage of their annual payment volume and are charged a fixed fee for the loan, which targets an annual percentage rate based on the overall credit assessment of the merchant. Loans are repaid through a fixed percentage of the merchant's future payment volume. The fee is fixed at the time the loan is extended. The fixed fee is amortized to interest income based on the amount repaid over the repayment period. We estimate the repayment period based on the merchant's payment processing history. There is no stated interest rate. There is a general requirement that at least 10% of the original amount of the loan plus the fixed fee must be repaid every 90 days. We calculate the repayment rate of the merchant's future payment volume so that repayment of the loan or advance and fixed fee is expected to generally occur within 9 to 12 months from the date of the loan or advance.

Loans held for sale are carried at the lower of cost or estimated market value in the aggregate. A valuation allowance is recorded when cost exceeds fair value based on our determination at the time of reclassification and periodically thereafter. Gains and losses are recorded in noninterest income based on the difference between sales proceeds and carrying value and impairments from reductions in carrying value.

Loans are reported as past due when either principal or interest is due and unpaid for a period of 30 days or more. The accrual of interest on loans is generally discontinued at the time the loan is 90 to 180 days delinquent, depending on the type of loan, unless the loan is well-secured and in process of collection. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful.

All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Loan Impairment and Allowance for Loan Losses

A loan is considered impaired when, based on current information and events, it is probable that WebBank will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments. When a loan has been identified as being impaired, the amount of impairment is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, when appropriate, the loan's observable fair value or the fair value of the collateral (less any selling costs) if the loan is collateral-dependent. If the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest, net of deferred loan fees or costs and unamortized premium or discount), an impairment is recognized by creating or adjusting an existing allocation of the ALLL, or by charging down the loan to its value determined in accordance with U.S. GAAP.

47

The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when the uncollectability of a loan or receivable balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The ALLL is evaluated on a regular basis and is based upon a periodic review of the collectability of the amounts due in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are classified as doubtful, substandard or loss. For such loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical loss experience and is adjusted for qualitative factors to cover uncertainties that could affect the estimate of probable losses. The ALLL is increased by charges to income and decreased by charge-offs (net of recoveries). The periodic evaluation of the adequacy of the allowance is based on WebBank's past loss experience, known and inherent risks in the portfolio, adverse situations that may affect the debtor's ability to repay, the estimated value of any underlying collateral and current economic conditions.

Inventories

Inventories are generally stated at the lower of cost (determined by the first-in, first-out method or average cost method) or market. Cost is determined by the last-in, first-out ("LIFO") method for certain precious metal inventory held in the U.S., and remaining precious metal inventory is primarily carried at fair value. For precious metal inventory, no segregation among raw materials, work in process and finished products is practicable. For other inventory, the cost of work in process and finished products comprises the cost of raw materials, direct labor and overhead costs attributable to the production of inventory.

Non-precious metal inventories are evaluated for estimated excess and obsolescence based upon assumptions about future demand and market conditions, and are adjusted accordingly. If actual market conditions are less favorable than those projected, future write-downs may be required.

Goodwill and Other Intangible Assets, Net

Goodwill, which is not amortized, represents the difference between the purchase price and the fair value of identifiable net assets acquired in a business combination. Goodwill is reviewed for impairment indicators throughout the year and tested for impairment annually in the fourth quarter. An entity can choose between two testing approaches:

a. Step 0 or Qualitative approach - An entity may assess qualitative factors to determine whether it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount, including goodwill. In evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, an entity should assess relevant events and circumstances. Examples of such events and circumstances would include pertinent macroeconomic conditions, industry and market considerations, overall financial performance and other factors.

An entity has an unconditional option to bypass this qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period.

b. Step 1 or Quantitative approach - The fair value of a reporting unit is calculated and compared with its carrying amount. There are several methods that may be used to estimate a reporting unit's fair value, including the income approach, market approach and/or cost approach. If the fair value of a reporting unit exceeds its carrying amount, there is no indication of impairment and further testing is not required. If the carrying amount of a reporting unit exceeds its fair value, then a second step of testing is required ("Step 2"). The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill.

For 2018, the Company utilized a qualitative approach for all of its reporting units, except for the Packaging business within its Diversified Industrial segment. Based on its qualitative assessment, the Company does not believe that it is more likely than not that the fair value of any of its reporting units tested under this approach is less than its carrying value. The Company performed a quantitative assessment of goodwill associated with its Packaging business due to a decline in market conditions and lower demand for certain of the Packaging business' product lines. The assessment was based on a combination of income and market approaches to estimate the fair value of the reporting unit, which indicated that the fair value of this reporting unit exceeded its carrying value. Significant assumptions used in the discounted cash flow analysis included expected future earnings and cash flows, which are based on management's current expectations, as well as the related risk-adjusted discount rate used to estimate

48

fair value. There were no goodwill impairment charges recorded as a result of these assessments. For 2017, the Company utilized a qualitative approach for all of its reporting units to assess goodwill, and there were no goodwill impairment charges recorded as a result of the assessment.

Other intangible assets with indefinite lives are not amortized, while other intangible assets with finite lives are amortized over their estimated useful lives. Intangible assets with finite lives are reviewed for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable (see "Long-Lived Asset Testing" below).

Intangible assets with indefinite lives, which are only within the Diversified Industrial segment, are tested for impairment at least annually, or when events or changes in circumstances indicate that it is more likely than not that the asset is impaired. Companies can use the same two testing approaches for indefinite-lived intangibles as for goodwill. For 2018 and 2017, the Company utilized a qualitative approach to assess its intangible assets with indefinite lives, and the results indicated no impairment in either of these years.

Derivatives

The Company uses various hedging instruments to reduce the impact of changes in precious metal prices and the effect of foreign currency fluctuations. In accordance with Accounting Standards Codification ("ASC") 815, Derivatives and Hedging, these instruments are recorded as either fair value hedges, economic hedges, cash flow hedges or derivatives with no hedging designation.

Precious Metals

The Company's precious metal and commodity inventories are subject to market price fluctuations. The Company enters into commodity futures and forward contracts to mitigate the impact of price fluctuations on its precious and certain non-precious metal inventories that are not subject to fixed price contracts. The Company's hedging strategy is designed to protect it against normal volatility; therefore, abnormal price changes in these commodities or markets could negatively impact the Company's earnings.

Fair Value Hedges. The fair values of these derivatives are recognized as derivative assets and liabilities on the Company's consolidated balance sheets. The net change in fair value of the derivative assets and liabilities, and the change in the fair value of the underlying hedged inventory, are recognized in the Company's consolidated statements of operations, and such amounts principally offset each other due to the effectiveness of the hedges. The fair value hedges are associated primarily with the Company's precious metal inventory carried at fair value.

Economic Hedges. As these derivatives are not designated as accounting hedges under ASC 815, they are accounted for as derivatives with no hedge designation. The derivatives are marked to market, and both realized and unrealized gains and losses are recorded in current period earnings in the Company's consolidated statements of operations. The economic hedges are associated primarily with the Company's precious metal inventory valued using the LIFO method.

Foreign Currency Forward Contracts

The Company enters into foreign currency forward contracts to hedge certain of its receivables and payables denominated in other currencies. In addition, the Company enters into foreign currency forward contracts to hedge the value of certain of its future sales and the value of its future purchases denominated in other currencies. The forward contracts that are used to hedge the risk of foreign exchange movement on its receivables and payables are accounted for as fair value hedges under ASC 815. The fair values of these derivatives are recognized as derivative assets and liabilities on the Company's consolidated balance sheets. The net change in fair value of the derivative assets and liabilities are recognized in the Company's consolidated statements of operations. The forward contracts that are used to hedge the value of the Company's future sales and purchases are accounted for as cash flow hedges in accordance with ASC 815. These hedges are fully effective and accordingly, the changes in fair value are recorded in AOCI and, at maturity, any gain or loss on the forward contract is reclassified from AOCI into the Company's consolidated statements of operations.

WebBank - Derivative Financial Instruments

WebBank's derivative financial instruments represent on-going economic interests in loans made after they are sold. These derivatives are carried at fair value on a gross basis in Other non-current assets on the Company's consolidated balance sheet. Gains and losses resulting from changes in fair value of these derivative instruments are accounted for in the Company's consolidated

49

statements of operations in Financial services revenue. Fair value represents the estimated amounts that WebBank would receive at the reporting date based on a discounted cash flow model for the same or similar instruments. WebBank does not enter into derivative contracts for speculative or trading purposes.

Property, Plant and Equipment, Net

Property, plant and equipment is recorded at cost. Depreciation of property, plant and equipment is recorded principally on the straight line method over the estimated useful lives of the assets, which range as follows: machinery & equipment 3 to 15 years and buildings & improvements 10 to 30 years. Leasehold improvements are amortized over the shorter of the terms of the related leases or the estimated useful lives of the improvements. Interest cost is capitalized for qualifying assets during the assets' acquisition period. Maintenance and repairs are charged to expense, and renewals and betterments are capitalized. Gain or loss on dispositions is recorded in Other (income) expense, net.

Long-Lived Asset Testing

The Company estimates the depreciable lives of property, plant and equipment, and reviews long-lived assets for impairment whenever events, or changes in circumstances, indicate the carrying amount of such assets may not be recoverable. If the carrying values of the long-lived assets exceed the sum of the undiscounted cash flows, an impairment charge is recognized in the amount by which the carrying values exceeds their fair values. The Company performs such assessments at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities, which is generally at the plant level, operating company level or the reporting unit level, dependent on the level of interdependencies in the Company's operations.

The Company considers various factors in determining whether an impairment test is necessary, including among other things: a significant or prolonged deterioration in operating results and projected cash flows; significant changes in the extent or manner in which assets are used; technological advances with respect to assets which would potentially render them obsolete; the Company's strategy and capital planning; and the economic climate in the markets it serves. When estimating future cash flows and if necessary, fair value, the Company makes judgments as to the expected utilization of assets and estimated future cash flows related to those assets. The Company considers historical and anticipated future results, general economic and market conditions, the impact of planned business and operational strategies and other information available at the time the estimates are made. The Company believes these estimates are reasonable; however, changes in circumstances or conditions could have a significant impact on its estimates, which might result in material impairment charges in the future.

Business Combinations

When the Company acquires a business, it allocates the purchase price to the assets acquired, liabilities assumed and any noncontrolling interests based on their fair values at the acquisition date. Significant judgment may be used to determine these fair values including the use of appraisals, discounted cash flow models, market value for similar purchases or other methods applicable to the circumstances. The assumptions and judgments made by the Company when recording business combinations will have an impact on reported results of operations in the future.

Revenue Recognition

Diversified Industrial and Energy Segments

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and has since issued amendments thereto (collectively referred to herein as "ASC 606"). In January 1, 2018, we adopted ASC 606 using the modified retrospective method applied to those contracts which were not completed as of the adoption date. Results for reporting periods beginning after December 31, 2017 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for those periods. Our revenue recognition accounting policies applied prior to adoption of ASC 606 are outlined in the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2017. The disclosures included herein reflect our accounting policies under ASC 606.

Diversified Industrial revenues related to product sales are recognized when control of the promised goods is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods. This condition is usually met at a point-in-time when the product has been shipped to the customer, or in certain circumstances when the product has been delivered to the customer, depending on the terms of the contract. However, revenues for certain custom

50

manufactured goods are recognized over time as the customer order is fulfilled (for example, contracts for sale of custom manufactured goods that do not have an alternative use and for which the Company has an enforceable right to payment). Certain customers may receive sales incentives, such as right of return, rebates, volume discounts and early payment discounts, which are accounted for as variable consideration. The Company estimates these amounts based on the expected incentive amount to be provided to customers and reduces revenues. Revenue is reported net of any sales or usage-based tax collected. Cash received from customers prior to shipment of goods, or otherwise not yet earned, is recorded as deferred revenue. Service revenues are generated primarily by the Energy segment's energy and sports businesses and by the repair and maintenance work performed on equipment used at mass merchants, supermarkets and restaurants in the Diversified Industrial segment. Service revenues are primarily recognized in the amount to which the entity has a right to invoice. The Company records all shipping and handling fees billed to customers as revenue. If revenue is recognized for the related good before the shipping and handling activities occur, the related costs of those shipping and handling activities are accrued.

The Company has also entered into rebate agreements with certain customers. These programs are typically structured to incentivize the customers to increase their annual purchases from the Company. The rebates are usually calculated as a percentage of the purchase amount, and such percentages may increase as the customer's level of purchases rise. Rebates are recorded as a reduction of net sales in the Company's consolidated statements of operations. As of December 31, 2018 and 2017, accrued rebates payable totaled $12,345 and $8,300, respectively, and are included in Accrued liabilities on the Company's consolidated balance sheets.

Financial Services Segment

WebBank generates revenue through a combination of interest income and non-interest income. Interest income is derived from interest and fees earned on loans and investments. Interest income is accrued on the unpaid principal balance, including amortization of premiums and accretion of discounts. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield over the estimated life of the loan. Non-interest income is primarily derived from premiums on the sale of loans, loan servicing fees, origination fees earned on loans and fee income on contractual lending arrangements.

Concentration of Revenue

No single customer accounted for 5% or more of the Company's consolidated revenues in 2018 or 2017. In 2018 and 2017, the 10 largest customers accounted for approximately 19% and 18%, respectively, of the Company's consolidated revenues.

Fair Value Measurements

The Company measures certain assets and liabilities at fair value (see Note 18 - "Fair Value Measurements"). Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair values of assets and liabilities are determined based on a three-level measurement input hierarchy. Level 1 inputs are quoted prices in active markets for identical assets or liabilities as of the measurement date. Level 2 inputs are other than quoted market prices that are observable, either directly or indirectly, for an asset or liability. Level 2 inputs can include quoted prices in active markets for similar assets or liabilities, quoted prices in a market that is not active for identical assets or liabilities, or other inputs that can be corroborated by observable market data. Level 3 inputs are unobservable for the asset or liability when there is little, if any, market activity for the asset or liability. Level 3 inputs are based on the best information available, and may include data developed by the Company.

Equity-Based Compensation

The Company accounts for restricted stock units granted to employees and non-employee directors as compensation expense, which is recognized in exchange for the services received. The compensation expense is based on the fair value of the equity instruments on the grant-date and is recognized as an expense over the service period of the recipients.

Income Taxes

SPLP and certain of its subsidiaries, as limited partnerships, are generally not responsible for federal and state income taxes, and their profits and losses are passed directly to their partners for inclusion in their respective income tax returns. SPLP's subsidiaries that are corporate entities are subject to federal and state income taxes and file corporate income tax returns.

51

SPLP's subsidiaries that are subject to income taxes use the liability method of accounting for such taxes. Under the liability method, deferred tax assets and deferred tax liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and deferred tax liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and deferred tax liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Such subsidiaries evaluate the recoverability of deferred tax assets and establish a valuation allowance when it is more likely than not that some portion of the deferred tax assets will not be realized.

When tax returns are filed, it is highly certain that most positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the Company's consolidated financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50% likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is provided for and reflected as a liability for unrecognized tax benefits on the Company's consolidated balance sheets, along with any associated interest and penalties that would be payable to the taxing authorities upon examination.

SPLP's policy is to record estimated interest and penalties related to the underpayment of income taxes as income tax expense in its consolidated statements of operations.

The Company does not release income tax effects from AOCI until the underlying asset or liability to which the income tax relates has been derecognized from the balance sheet or otherwise terminated.

Foreign Currency Translation

Assets and liabilities of SPLP's foreign subsidiaries are translated at current exchange rates and related revenues and expenses are translated at average rates of exchange in effect during the year. Resulting cumulative translation adjustments are recorded as a separate component of other comprehensive income or loss. Gains and losses arising from transactions denominated in a currency other than the functional currency of the reporting entity are included in earnings.

Legal Contingencies

The Company provides for legal contingencies when the liability is probable and the amount of the associated loss is reasonably estimable. The Company regularly monitors the progress of legal contingencies and revises the amounts recorded in the period in which a change in estimate occurs.

Environmental Liabilities

The Company accrues for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study.

Such accruals are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

New or Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASC 606 relating to revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services, and the guidance defines a five-step process to achieve this core principle. ASC 606 also requires additional disclosure about the nature, amount, timing and uncertainty of revenues and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The Company adopted ASC 606 as of January 1, 2018 using the modified retrospective transition method. For additional information, see Note 3 - "Revenues."

52

In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10), which eliminates the requirement to classify equity securities with readily determinable market values as either available-for-sale or trading securities, and requires that equity investments, other than those accounted for under the traditional equity method of accounting, be measured at their fair value with changes in fair value recognized in net income or loss. In the past, changes in fair value were reported in the Company's consolidated statement of comprehensive (loss) income and in AOCI. Equity investments that do not have readily determinable market values may be measured at cost under ASU 2016-01, subject to an assessment for impairment. We adopted ASU 2016-01 effective January 1, 2018. Upon adoption, we recorded a cumulative effect reclassification adjustment from AOCI to Partners' capital of $91,078, which represented the accumulated net unrealized gain on equity securities that was held in AOCI as of December 31, 2017. See also Note 15 - "Capital and Accumulated Other Comprehensive Loss." Furthermore, to have a comparable presentation in our prior-period financial statements after adoption of ASU 2016-01 in 2018, we reclassified realized gains of $790 for the year ended December 31, 2017 from Other (income) expense, net to Realized and unrealized losses (gains) on securities, net in both the consolidated statement of operations and consolidated statement of cash flows for 2017.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is effective for public companies for annual reporting periods beginning after December 15, 2018, including interim periods within those fiscal years. The new standard establishes a right-of-use ("ROU") model that requires a lessee to record a ROU asset and a lease liability, measured on a discounted basis, on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which clarified various aspects of the guidance under ASU 2016-02. Originally, entities were required to adopt ASU 2016-02 using a modified retrospective approach, which required prior periods to be presented under this new standard with certain practical expedients available. However, in July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which now allows entities the option of recognizing the cumulative effect of applying the new standard as an adjustment to the opening balance of retained earnings in the year of adoption (January 1, 2019) while continuing to present all prior periods under previous lease accounting guidance. ASU 2016-02 and its various amendments and clarifications are collectively referred to herein as "ASC 842."

The Company will adopt ASC 842 in the first quarter of 2019 using the alternative modified transition method. Under this method, the cumulative-effect adjustment to the opening balance of retained earnings is recognized on the date of adoption with prior periods not restated. The Company will also elect to use the package of practical expedients permitted under the transition guidance, such as, carryforward of our historical lease classification, no reassessment on whether an expired or existing contract contains an embedded lease, no reassessment of initial direct costs for any leases that exist prior to adoption of the new standard and to consolidate lease and non-lease components. We are also electing to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term.

The Company has completed its implementation plan for the new lease standard, which includes an information system, and business process and control changes, to accumulate the appropriate data in order to calculate and record the recognition of ROU assets, lease liabilities and the related expense recognition. We estimate that based on our portfolio of leases as of December 31, 2018, approximately $51,000 of ROU lease assets and $53,000 of lease liabilities will be recognized on our consolidated balance sheet upon adoption, primarily relating to building rentals.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new standard changes the impairment model for most financial assets that are measured at amortized cost and certain other instruments, including trade receivables, from an incurred loss model to an expected loss model and adds certain new required disclosures. Under the expected loss model, entities will recognize estimated credit losses to be incurred over the entire contractual term of the instrument rather than delaying recognition of credit losses until it is probable the loss has been incurred. The new standard is effective for the Company's 2020 fiscal year with early adoption permitted for all entities in fiscal years beginning after December 15, 2018. The Company is currently evaluating the potential impact of this new guidance; however, it expects that it could have a significant impact on the Company's ALLL.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This new standard provides guidance to help decrease diversity in practice in how certain cash receipts and cash payments are classified in the statement of cash flows. The amendments in ASU 2016-15 provide guidance on eight specific cash flow issues. We adopted ASU 2016-15 effective January 1, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

53

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This new standard provides guidance on the classification of restricted cash in the statement of cash flows. We adopted ASU 2016-18 effective January 1, 2018. As a result of the adoption of ASU 2016-18, in the consolidated statement of cash flows for the year ended December 31, 2017, we reclassified $15,629 of restricted cash.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This new standard provides guidance to help determine more clearly what is a business acquisition, as opposed to an asset acquisition.The amendments provide a screen to help determine when a set of components is a business by reducing the number of transactions in an acquisition that need to be evaluated. The new standard states that to classify the acquisition of assets as a business, there must be an input and a substantive process that jointly contribute to the ability to create outputs, with outputs being defined as the key elements of the business. If all of the fair value of the assets acquired are concentrated in a single asset group, this would not qualify as a business. The Company adopted ASU 2017-01 effective January 1, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This new standard simplifies subsequent measurements of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, entities will perform their interim or annual goodwill impairment testing by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge based on the amount that the carrying amount exceeds the reporting unit's fair value. The loss recognized should not exceed the total goodwill allocated to the reporting unit. The amendments in ASU 2017-04 are effective for the Company's 2020 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This new standard requires the components of net benefit cost to be disaggregated within the statement of operations, with service cost being included in the same line item as other compensation costs, and any other components being presented outside of operating income. The Company adopted ASU 2017-07 effective January 1, 2018. Since the Company's significant pension plans have been frozen, there is no substantial service cost associated with such plans and therefore, the adoption of ASU 2017-07 did not have a material impact on the Company's consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. This new standard provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The standard states that entities should account for the effects of a modification unless the fair value of the modified award is the same as the fair value of the original award, the vesting conditions do not change, and the classification as an equity instrument or a liability instrument is the same. We adopted ASU 2017-09 effective January 1, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This new standard was created to refine and expand hedge accounting for both financial and commodity risk in order to simplify the current application of hedge accounting guidance in current U.S. GAAP. This new standard creates more transparency around how hedging results are presented, both in the notes and on the face of the financial statements. The amendments in ASU 2017-12 are effective for the Company's 2019 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The new standard provides financial statement preparers with an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the federal Tax Cuts and Jobs Act ("Act") is recorded. The amendments in ASU 2018-02 are effective for the Company's 2019 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In March 2018, the FASB issued ASU 2018-05, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. ASU 2018-05 applies to income tax effects from the enactment of the Act in December 2017. ASU 2018-05 allows a Company to report as provisional those amounts where the Company does not have the necessary information available, prepared or analyzed in reasonable detail to complete the accounting under Accounting Standards Codification Topic 740. ASU 2018-05 further allows a measurement period, not to exceed one year from the enactment date of Act, during which an entity may need to reflect adjustments to its provisional amounts. ASU 2018-05 requires that any adjustments to provisional amounts during the

54

measurement period be included in income from continuing operations as an adjustment to tax expense or benefit, and also requires certain disclosures. The provisions of ASU 2018-05 were effective as of the enactment date of the Act, December 22, 2017.

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This new standard was created to simplify the accounting for share-based payments to nonemployees. This standard provides guidance on how to account for share-based payment transactions with nonemployees in which a grantor acquires goods or services to be used or consumed in the grantor's own operations by issuing share-based payment awards. The amendments in ASU 2018-07 are effective for the Company's 2019 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on fair value measurements. The amendments in ASU 2018-13 are effective for the Company's 2020 fiscal year, except that the standard permits an entity to early adopt any removed or modified disclosures upon issuance of ASU No. 2018-13 and delay adoption of the additional disclosures until the effective date. Because ASU 2018-13 affects disclosure only, management does not expect that the full adoption of this standard will have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 modifies the disclosure requirements for employers that sponsor defined benefit pension and other post-retirement plans. The amendments in ASU 2018-14 are effective for the Company's 2021 fiscal year. Because ASU 2018-14 affects disclosure only, management does not expect that the adoption of this standard will have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments in ASU 2018-15 are effective for the Company's 2020 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

3. REVENUES

Adoption of ASC 606, "Revenue from Contracts with Customers"

On January 1, 2018, the Company adopted ASC 606 for all contracts with customers using the modified retrospective transition method. The Company recognized a net increase of $1,034 to Partners' capital due to the cumulative impact of adopting ASC 606. The impact to Partners' capital was primarily related to the timing of when revenue is recognized. While revenue from most contracts will continue to be recognized at a point-in-time, revenue from other contracts (for example, contracts for sale of custom manufactured goods that do not have an alternative use and for which the Company has an enforceable right to payment) will be recognized over time. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. For the year ended December 31, 2018, ASC 606 did not have a material impact on the Company's consolidated financial statements, including total revenue.

Revenue Recognition Accounting Policies

Revenues are recognized when control of the promised goods or services are transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

The Company records all shipping and handling fees billed to customers as revenue. The Company has elected to account for shipping and handling activities that are performed after the customer obtains control of a good as activities to fulfill the promise to transfer the good. If revenue is recognized for the related good before the shipping and handling activities occur, the related costs of those shipping and handling activities are accrued.

Sales and usage-based taxes are excluded from revenues. The Company does not have any material service-type warranty arrangements. The expected costs associated with the Company's assurance warranties continue to be recognized as expense when the products are sold. The Company does not have any material significant financing arrangements as payment is received shortly after the goods are sold or services are performed.

Standalone Selling Price

55

Generally, the Company's sales contracts with customers contain only one performance obligation. In certain circumstances, contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines the standalone selling price based on the prices charged to similar customers or by using the expected cost plus margin approach. The Company's performance obligations are generally part of contracts with customers that have a duration of less than one year, and therefore, the Company has not provided disclosures with respect to remaining performance obligations.

Practical Expedients and Exemptions

Given the typical duration of the Company's contracts with customers, as noted directly above, is less than one year, in accordance with the standard, the Company generally expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within Selling, general and administrative expenses.

For certain of the services that the Company's Diversified Industrial and Energy segments provide, the Company has determined that it has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of the Company's performance completed to date, and therefore, the Company recognizes revenue in the amount to which the entity has a right to invoice.

Disaggregation of Revenues

Revenues are disaggregated at the Company's segment level since the segment categories depict how the nature, amount, timing and uncertainty of revenues and cash flows are affected by economic factors. For additional details related to the Company's reportable segments see Note 21 - "Segment Information."

The following table presents the Company's revenues disaggregated by geography for the year ended December 31, 2018. The Company's revenues are primarily derived domestically. Foreign revenues are based on the country in which the legal subsidiary generating the revenue is domiciled. Revenue from any single foreign country was not material to the Company's consolidated financial statements.

	Year Ended December 31, 2018
United States	$	1,368,778
Foreign (a)	215,836
Total revenue	$	1,584,614

(a) Foreign revenues are primarily related to the Company's API Group plc ("API") business, which is domiciled in the United Kingdom.

Diversified Industrial Revenues

The Diversified Industrial segment is comprised of manufacturers of engineered niche industrial products. The majority of revenues recognized are for the sale of manufactured goods in the United States. Other revenue recognized is for repair and maintenance services. Customer contracts are generally short-term in nature and are based on individual customer purchase orders. The terms and conditions of the customer purchase orders are dictated by either the Company's standard terms and conditions or by a master service agreement.

Diversified Industrial revenues related to product sales are recognized when control of the promised goods is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods. This condition is usually met at a point-in-time when the product has been shipped to the customer, or in certain circumstances when the product has been delivered to the customer, depending on the terms of the contract. However, revenues for certain custom manufactured goods are recognized over time as the customer order is fulfilled (for example, contracts for sale of custom manufactured goods that do not have an alternative use and for which the Company has an enforceable right to payment). Generally, a cost incurred input method is used to determine the timing of revenue recognition for over time arrangements. Service revenues are primarily recognized in the amount to which the entity has a right to invoice.

Certain customers may receive sales incentives, such as right of return, rebates, volume discounts and early payment discounts, which are accounted for as variable consideration. The Company estimates these amounts based on the expected incentive amount to be provided to customers and reduces revenues, and these estimates are typically constrained. The Company adjusts its estimate of revenue at the earlier of when the expected value or most likely amount of consideration we expect to receive changes or when the consideration becomes fixed.

56

Energy Revenues

The Energy segment provides drilling and production services to the oil & gas industry in the United States. The services provided include well completion and recompletion, well maintenance and workover, snubbing, flow testing, down hole pumping, plug and abatement, well logging and perforating wireline services. Service revenues are recognized in the amount to which the entity has a right to invoice. Consideration for Energy contracts is generally fixed.

A portion of Energy revenues are service revenues related to Energy's youth sports business. These service revenues are recognized when services are provided to the customer, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those services. Consideration for the Energy's sports business contracts is generally fixed.

Financial Services Revenues

WebBank generates revenues through a combination of interest income and non-interest income. Interest income is derived from interest and fees earned on loans and investments. Interest income is accrued on the unpaid principal balance, including amortization of premiums and accretion of discounts. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield over the estimated life of the loan. Non-interest income is primarily derived from premiums on the sale of loans, loan servicing fees, origination fees earned on loans and fee income on contractual lending arrangements. WebBank's revenue streams are primarily accounted for outside of the scope of ASC 606.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed trade receivables, unbilled receivables (contract assets), return assets and deferred revenue (contract liabilities) on the consolidated balance sheet.

Contract Assets

Unbilled receivables arise when the timing of billings to customers differs from the timing of revenue recognition, such as when the Company recognizes revenue over time before a customer can be billed. Contract assets are classified as Prepaid expenses and other current assets on the consolidated balance sheet. The balances of contract assets as of December 31, 2018 and January 1, 2018 were $8,969 and $3,480, respectively. As of December 31, 2018, and January 1, 2018, the Company's return assets account was not material.

Contract Liabilities

The Company records deferred revenues when cash payments are received or due in advance of the Company's performance, including amounts which are refundable, which are recorded as contract liabilities. Contract liabilities are classified as Other current liabilities on the consolidated balance sheet based on the timing of when the Company expects to recognize revenue. The balances of contract liabilities as of December 31, 2018 and January 1, 2018 were $5,900 and $3,920, respectively. For the year ended December 31, 2018, the Company recognized revenue of $3,865 that was included in the contract liability balance at the date of adoption.

4. ACQUISITIONS

2018 Acquisitions

On June 1, 2018, the Company completed the acquisition of PST Group, Inc. ("PST") located in Muskego, Wisconsin for approximately $4,620. PST manufactures precision-engineered threaded components and custom ball screw assemblies, providing linear motion and power transmission solutions across a range of industries. PST is included in the Company's Diversified Industrial segment.

On February 16, 2018, the Company completed the acquisition of certain assets and liabilities of Dunmore Corporation in the U.S. and the share purchase of Dunmore Europe GmbH in Germany (collectively, "Dunmore") for a purchase price of $69,604, which includes assumed debt and is subject to an earn-out based on future earnings during the period from January 1, 2018 through December 31, 2019, as provided in the purchase agreement. In no case will the purchase price, including the potential earn-out, exceed $80,000. Dunmore manufactures and distributes coated, laminated and metallized films for engineered applications in the imaging, aerospace, insulation and solar photo-voltaic markets and also provides products for custom and special applications.

57

Dunmore reports into the Company's Packaging business in its Diversified Industrial segment. In connection with the Dunmore acquisition, the Company recorded inventories, property, plant and equipment, other intangible assets and goodwill on a preliminary basis, totaling approximately $7,700, $30,600, $19,900 and $13,006, respectively, as well as other assets and liabilities. Other intangible assets consist of customer relationships of $12,600, trade names of $3,300, developed technology of $3,300 and customer order backlog of $700. The expected useful lives are 15 years for customer relationships, indefinite for trade names and 10 years for developed technology. The customer order backlog was amortized based on the expected period over which the orders were fulfilled of four months. The goodwill from the Dunmore acquisition consists largely of the synergies expected from combining the operations of Dunmore and the Company's existing Packaging business. The goodwill assigned to Dunmore Corporation of $5,176 is expected to be deductible for income tax purposes, while the goodwill assigned to Dunmore Europe GmbH of $7,830 is not tax deductible. The preliminary purchase price allocation is subject to finalization of valuations of certain acquired assets and liabilities.

On December 31, 2018, the Company increased its ownership in a former equity investee, iGo, Inc. ("iGo") from 45.8% to 80.2%. For further discussion, see Note 15 - "Capital and Accumulated Other Comprehensive Loss."

2017 Acquisition

On May 19, 2017, the Company acquired an 80% interest in Basin Well Logging Wireline Services, Inc. ("Basin") located in Farmington, New Mexico for approximately $5,100. Basin provides wireline services to major oil & gas exploration and production companies in the U.S. and specializes in cased-hole wireline logging and perforating services for exploration and production companies with wells in New Mexico, Texas, Utah, Arizona and Colorado. In connection with the Basin acquisition, which was not material to SPLP's operations, goodwill totaling approximately $2,353 was recorded.

5. DIVESTITURES AND ASSET IMPAIRMENT CHARGES

Divestitures

During 2017, API sold two facilities for approximately $12,500 and recorded gains on sale totaling approximately $650, which are recorded in Other (income) expense, net in the Company's consolidated statements of operations. During 2017, the Company also sold its Micro-Tube Fabricators, Inc. business, which produced precision fabricated tubular components primarily for the medical industry and was included in the Company's Diversified Industrial segment, for approximately $2,500 and recorded a loss on sale of $400, which is also included in Other (income) expense, net. The sales price was paid $2,000 in cash at closing and a $500 subordinated promissory note, which has been fully collected. In addition, the Company was eligible to receive up to $1,000 of additional contingent consideration if certain sales volume milestones were met between the sale date and December 31, 2019. In 2017, the Company earned $755 of additional contingent consideration. The remaining $245 of contingent consideration was earned in 2018.

Asset Impairment Charges

During 2018, the Company recorded non-cash impairment charges totaling approximately $7,600, calculated using the income approach, primarily associated with the loss of acquired customer relationships in the Company's Packaging business in its Diversified Industrial segment.

During 2017, the Company recorded a non-cash impairment charge of $2,028 in its Energy segment related to an other-than-temporary impairment of a certain investment.

6. LOANS RECEIVABLE, INCLUDING LOANS HELD FOR SALE

Major classification of WebBank's loans receivable, including loans held for sale, at December 31, 2018 and 2017 are as follows:

	Total										Current						Non-current
	December 31, 2018			%		December 31, 2017			%		December 31, 2018			December 31, 2017			December 31, 2018		December 31, 2017

Loans receivable, including loans held for sale (a)											$	341,890		$	182,242		$	164,375	$	87,826

(a) The carrying value is considered to be representative of fair value because the rates of interest are not significantly different from market interest rates for instruments with similar maturities. The fair value of loans receivable, including loans held for sale, was $510,543 and $270,068 at December 31, 2018 and 2017, respectively.

Loans with a carrying value of approximately $56,851 and $57,436 were pledged as collateral for potential borrowings at December 31, 2018 and 2017, respectively. WebBank serviced $3,044 and $3,125 in loans for others at December 31, 2018 and 2017, respectively.

WebBank sold loans totaling $21,116,184 in 2018 and $16,471,432 in 2017 that were classified as loans held for sale. The sold loans were derecognized from the consolidated balance sheets. Loans classified as loans held for sale primarily consist of credit cards and other consumer and small business loans. The loans are mainly sold to WebBank's partners. Amounts added to loans held for sale during these same periods were $21,167,553 and $16,528,082, respectively.

Allowance for Loan Losses

The ALLL represents an estimate of probable and estimable losses inherent in the loan portfolio as of the balance sheet date. Losses are charged to the ALLL when incurred. Generally, commercial loans are charged off or charged down at the point

58

at which they are determined to be uncollectible in whole or in part. Consumer term loans are charged off at 120 days past due and open-end consumer and small and medium business loans are charged off at 180 days past due unless the loan is well secured and in the process of collection. The amount of the ALLL is established by analyzing the portfolio at least quarterly and a provision for or reduction of loan losses is recorded so that the ALLL is at an appropriate level at the balance sheet date. The methodologies used to estimate the ALLL depend upon the impairment status and portfolio segment of the loan. Loan groupings are created for each loan class and are then graded against historical and industry loss rates.

After applying historic loss experience, the quantitatively derived level of ALLL is reviewed for each segment using qualitative criteria. Various risk factors are tracked that influence our judgment regarding the level of the ALLL across the portfolio segments. Primary qualitative factors that may be reflected in the quantitative models include:

• Asset quality trends

• Risk management and loan administration practices

• Portfolio management and controls

• Effect of changes in the nature and volume of the portfolio

• Changes in lending policies and underwriting policies

• Existence and effect of any portfolio concentrations

• National economic business conditions and other macroeconomic adjustments

• Regional and local economic and business conditions

• Data availability and applicability

• Industry monitoring

• Value of underlying collateral

Changes in these factors are reviewed to ensure that changes in the level of the ALLL are consistent with changes in these factors. The magnitude of the impact of each of these factors on the qualitative assessment of the ALLL changes from quarter to quarter according to the extent these factors are already reflected in historic loss rates and according to the extent these factors diverge from one another. Also considered is the uncertainty inherent in the estimation process when evaluating the ALLL. Changes in the ALLL are summarized as follows:

Credit Quality Indicators

In addition to the past due and nonaccrual criteria, loans are analyzed using a loan grading system. Generally, internal grades are assigned to loans based on the performance of the loans, financial/statistical models and loan officer judgment. For consumer loans and some commercial and industrial loans, the primary credit quality indicator is payment status. Reviews and grading of loans with unpaid principal balances of $100 or more is performed once per year. Grades follow definitions of Pass, Special Mention, Substandard and Doubtful, which are consistent with published definitions of regulatory risk classifications. The definitions of Pass, Special Mention, Substandard and Doubtful are summarized as follows:

• Pass: An asset in this category is a higher quality asset and does not fit any of the other categories described below. The likelihood of loss is considered remote.

• Special Mention: An asset in this category has a specific weakness or problem but does not currently present a significant risk of loss or default as to any material term of the loan or financing agreement.

• Substandard: An asset in this category has a developing or currently minor weakness or weaknesses that could result in loss or default if deficiencies are not corrected or adverse conditions arise.

• Doubtful: An asset in this category has an existing weakness or weaknesses that have developed into a serious risk of significant loss or default with regard to a material term of the financing agreement.

Impaired Loans

Loans are considered impaired when, based on current information and events, it is probable that WebBank will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments. When loans are impaired, an estimate of the amount of the balance that is impaired is made and a specific reserve is assigned to the loan based on the estimated present value of the loan's future cash flows discounted at the loan's effective interest rate, the observable market price of the loan or the fair value of the loan's underlying collateral less the cost to sell. When the impairment is based on the fair value of the loan's underlying collateral, the portion of the balance that is impaired is charged off, such that these loans do not have a specific reserve in the ALLL. Payments received on impaired loans that are accruing are recognized in interest income, according to the contractual loan agreement. WebBank recognized $122 and $4 on impaired loans for the years ended December 31, 2018 and 2017, respectively. Payments received on impaired loans that are on nonaccrual are not recognized in interest income, but are applied as a reduction to the principal outstanding. Payments are recognized when cash is received. Information on impaired loans is summarized as follows:

10. INVESTMENTS

Short-Term Investments

Marketable Securities

The Company's short-term investments primarily consist of its marketable securities portfolio. The classification of marketable securities as a current asset is based on the intended holding period and realizability of the investments. The Company's portfolio of marketable securities at December 31, 2018 and 2017 was as follows:

	December 31, 2018											December 31, 2017
	Cost			Gross Unrealized Gains		Gross Unrealized Losses			Fair value			Cost			Gross Unrealized Gains		Gross Unrealized Losses			Fair value
Short-term deposits	$	21,064		$	—	$	—		$	21,064		$	35,834		$	—	$	—		$	35,834

Proceeds from sales of marketable securities were approximately $47,200 and $16,596 in 2018 and 2017, respectively. The Company determines gains and losses from sales of marketable securities based on specific identification of the securities sold. Gross realized gains and losses from sales of marketable securities, which are reported as a component of Realized and unrealized losses (gains) on securities, net in the Company's consolidated statements of operations, were as follows:

	Year Ended December 31,
	2018			2017
Gross realized gains	$	16,499		$	637
Gross realized losses	(5,129		)	(545		)
Realized gains, net	$	11,370		$	92

Effective January 1, 2018 upon adoption of ASU 2016-01, unrealized gains or losses due to changes in fair value of securities are being accounted for as a component of Realized and unrealized losses (gains) on securities, net in the Company's consolidated statement of operations. Prior to January 1, 2018, changes in fair value were recognized in Partners' capital as other comprehensive income or loss, except for other-than-temporary impairments, which were reflected as a reduction of cost and charged to the consolidated statements of operations.

The fair value of marketable securities with unrealized losses at December 31, 2018 and 2017, and the duration of time that such losses had been unrealized, were as follows:

63

	Less than 12 Months					12 Months or Greater					Total
	Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses
December 31, 2018:
Corporate securities	$	396	$	(322	)	$	1,043	$	(2,772	)	$	1,439	$	(3,094	)
Total	$	396	$	(322	)	$	1,043	$	(2,772	)	$	1,439	$	(3,094	)

December 31, 2017:
Corporate securities	$	5,801	$	(2,558	)	$	398	$	(85	)	$	6,199	$	(2,643	)
Total	$	5,801	$	(2,558	)	$	398	$	(85	)	$	6,199	$	(2,643	)

The corporate securities with gross unrealized losses primarily consist of investments in equity securities of publicly traded entities. In 2017, the Company evaluated such securities to determine if certain unrealized losses represented other-than-temporary impairments. This determination was based on several factors, including adverse changes in the market conditions and economic environments in which the entities operate, as well as the length of time and extent to which fair value had been less than the cost basis, the financial condition and near-term prospects of the entities, and the intent and ability to hold the corporate securities for a period of time sufficient to allow for any anticipated recovery in market value. The Company recognized asset impairment charges of $2,028 for the year ended December 31, 2017.

On November 14, 2017, the Company entered into a credit agreement ("Credit Agreement") that consolidated a number of its existing credit facilities into one combined, revolving credit facility covering substantially all of the Company's subsidiaries, with the exception of WebBank. The Credit Agreement provided for a revolving credit facility in an aggregate principal amount not to exceed $600,000, including a $55,000 subfacility for swing line loans and a $50,000 subfacility for standby letters of credit. Borrowings under the Credit Agreement bear interest, at the borrower's option, at annual rates of either the Base Rate or the Euro-Rate, as defined, plus an applicable margin as set forth in the Credit Agreement (1.50% and 2.50%, respectively, for Base Rate and Euro-Rate borrowings at December 31, 2018), and the Credit Agreement provides for a commitment fee to be paid on unused borrowings. The weighted average interest rate on the Credit Agreement was 4.93% at December 31, 2018. At December 31, 2018, letters of credit totaling $11,153 had been issued under the Credit Agreement, including $3,709 of the letters of credit guaranteeing various insurance activities, and $7,444 for environmental and other matters. The Credit Agreement permits SPLP, the parent, to fund the dividends on its preferred units and its routine corporate expenses. The Company's total availability under the Credit Agreement, which is based upon earnings and certain covenants as described in the Credit Agreement, was approximately $42,900 as of December 31, 2018.

On April 27, 2018, the Company entered into a first amendment to the Credit Agreement to allow the Company to (i) exercise certain subscription rights in BW common shares, (ii) increase the maximum aggregate principal amount to $700,000,

65

(iii) increase the defined leverage ratios under the Credit Agreement by 0.25 "turns" for the fiscal quarters ending June 30, 2018, September 30, 2018 and December 31, 2018 and (v) make certain administrative changes.

On December 31, 2018, the Company entered into a second amendment to the Credit Agreement to allow the Company to (i) enter into the iGo transaction discussed in Note 15 - "Capital and Accumulated Other Comprehensive Loss," (ii) join iGo to the Credit Agreement and grant the lenders a security interest in its assets, (iii) provide an $18,500 sublimit for iGo's and its subsidiaries' borrowings and (iv) make certain administrative changes.

On January 31, 2019, the Company entered into a third amendment to the Credit Agreement to allow the Company to (i) convert $200,000 of the revolving credit commitments into a term loan with quarterly amortization equating to 5.0% per annum, (ii) amend certain defined leverage ratios under the Credit Agreement, increasing allowable leverage by 0.25 "turns" on a permanent basis through the maturity of the Credit Agreement, (iii) eliminate certain previously allowed investments, which would have reduced collateral available to the Company's lenders and (iv) make certain administrative changes. Accordingly, this third amendment to the Credit Agreement will add the following required principal repayments to the above long-term debt maturity table: $7,500 in 2019 and $10,000 in each of 2020, 2021 and 2022.

The Credit Agreement will expire, with all amounts outstanding due and payable, onNovember 14, 2022. The Credit Agreement is guaranteed by substantially all existing and thereafter acquired assets of the borrowers and the guarantors, as defined in the agreement,and a pledge of all of the issued and outstanding shares of capital stock of each of the borrowers' and guarantors' subsidiaries, and is fully guaranteed by the guarantors. The Credit Agreement is subject to certain mandatory prepayment provisions and restrictive and financial covenants, which include a maximum ratio limit on Total Leverage and a minimum ratio limit on Interest Coverage, as defined. The Company was in compliance with all financial covenants atDecember 31, 2018.

13. FINANCIAL INSTRUMENTS

At December 31, 2018 and 2017, financial instrument liabilities and related restricted cash consisted of $12,434 and $15,629, respectively, related to short sales of corporate securities. Full year activity is summarized below for financial instrument liabilities and related restricted cash:

	Year Ended December 31,
	2018			2017
Balance, beginning of period	$	15,629		$	12,640
Settlement of short sales of corporate securities	(3,100		)	(94		)
Short sales of corporate securities	26			165
Net investment (gains) losses	(121		)	2,918
Balance, end of period	$	12,434		$	15,629

Short Sales of Corporate Securities

From time to time, the Company enters into short sale transactions on certain corporate securities in which it receives proceeds from the sale of such securities and incurs obligations to deliver such securities at a later date. Upon initially entering into such short sale transactions, the Company recognizes a liability equal to the fair value of the obligation, with a comparable amount of cash and cash equivalents reclassified as restricted cash. Subsequent changes in the fair value of such obligations, determined based on the closing market price of the securities, are recognized currently as gains or losses in the consolidated statements of operations, with a comparable adjustment made between unrestricted and restricted cash.

Foreign Currency Forward Contracts

The Company enters into foreign currency forward contracts to hedge certain of its receivables and payables denominated in other currencies. In addition, the Company enters into foreign currency forward contracts to hedge the value of certain of its future sales denominated in Euros and the value of certain of its future purchases denominated in USD. These hedges are associated with certain of the Company's operations located in the United Kingdom and have settlement dates ranging through December 2019. The forward contracts that are used to hedge the risk of foreign exchange movement on its receivables and payables are accounted for as fair value hedges. At December 31, 2018, there were contracts in place to buy Sterling and sell Euros in the amount of €9,800. The fair values of these derivatives are recognized as derivative assets and liabilities on the Company's consolidated balance sheets. The net change in fair value of the derivative assets and liabilities are recognized in the Company's consolidated statements of operations. The forward contracts that are used to hedge the value of the Company's future sales and purchases are accounted for as cash flow hedges. At December 31, 2018, there were contracts in place to hedge the value of future

66

sales denominated in Euros in the amount of €10,300 and the value of future purchases denominated in USD in the amount of $450. These hedges are fully effective, and, accordingly, the changes in fair value are recorded in AOCI and, at maturity, any gain or loss on the forward contract is reclassified from AOCI into the Company's consolidated statements of operations.

WebBank - Economic Interests in Loans

WebBank's derivative financial instruments represent on-going economic interests in loans made after they are sold. These derivatives are carried at fair value on a gross basis in Other non-current assets on the Company's consolidated balance sheets and are classified within Level 3 in the fair value hierarchy (see Note 18 - "Fair Value Measurements"). At December 31, 2018, outstanding derivatives mature within 5 years. Gains and losses resulting from changes in the fair value of derivative instruments are accounted for in the Company's consolidated statements of operations in Financial services revenue. Fair value represents the estimated amounts that WebBank would receive or pay to terminate the contracts at the reporting date based on a discounted cash flow model for the same or similar instruments. WebBank does not enter into derivative contracts for speculative or trading purposes.

Precious Metal and Commodity Inventories

As of December 31, 2018, the Company had the following outstanding forward contracts with settlement dates through January 2019. There were no futures contracts outstanding at December 31, 2018.

Commodity	Amount	Notional Value
Silver	264,822 ounces	$	3,993
Gold	2,733 ounces	$	3,467
Palladium	775 ounces	$	951
Copper	150,000 pounds	$	388
Tin	20 metric tons	$	392

Of the total forward contracts outstanding, 18,895 ounces of silver and substantially all the copper contracts are designated and accounted for as fair value hedges and are associated primarily with the Company's precious metal inventory carried at fair value. The remaining outstanding forward contracts for silver, and all the contracts for gold, palladium and tin, are accounted for as economic hedges.

The forward contracts were made with a counterparty rated Aa2 by Moody's. Accordingly, the Company has determined that there is minimal credit risk of default. The Company estimates the fair value of its derivative contracts through the use of market quotes or with the assistance of brokers when market information is not available. The Company maintains collateral on account with the third-party broker, which varies in amount depending on the value of open contracts.

The fair value and carrying amount of derivative instruments on the Company's consolidated balance sheets and the effect of derivative instruments in the Company's consolidated statements of operations are shown in the following tables:

Financial Instruments with Off-Balance Sheet Risk

WebBank is a party to financial instruments with off-balance sheet risk. In the normal course of business, these financial instruments include commitments to extend credit in the form of loans as part of WebBank's lending arrangements. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the consolidated balance sheets. The contractual amounts of those instruments reflect the extent of involvement WebBank has in particular classes of financial instruments.

At December 31, 2018 and 2017, WebBank's undisbursed loan commitments totaled $130,697 and $148,529, respectively. Commitments to extend credit are agreements to lend to a borrower who meets the lending criteria through one of WebBank's lending agreements, provided there is no violation of any condition established in the contract with the counterparty to the lending arrangement.

Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since certain of the commitments are expected to expire without the credit being extended, the total commitment amounts do not necessarily represent future cash requirements. WebBank evaluates each prospective borrower's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by WebBank upon extension of credit, is based on management's credit evaluation of the borrower and WebBank's counterparty.

WebBank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. WebBank uses the same credit policy in making commitments and conditional obligations as it does for on-balance sheet instruments.

14. PENSION AND OTHER POST-RETIREMENT BENEFITS

The Company maintains several qualified and non-qualified pension plans and other post-retirement benefit plans. The Company's significant pension plans are discussed below. The Company's other pension and post-retirement benefit plans are not significant individually or in the aggregate.

Qualified Pension Plans - HNH

The Company's subsidiary, Handy & Harman Ltd. ("HNH") and its subsidiary, Handy & Harman ("H&H"), sponsor a defined benefit pension plan, the WHX Pension Plan, covering many of H&H's employees and certain employees of H&H's former subsidiary, Wheeling-Pittsburgh Corporation ("WPC"). The WHX Pension Plan was established in May 1998 as a result of the merger of the former H&H plans, which covered substantially all H&H employees, and the WPC plan. The WPC plan, covering most United Steel Workers of America-represented employees of WPC, was created pursuant to a collective bargaining agreement ratified on August 12, 1997. Prior to that date, benefits were provided through a defined contribution plan, the Wheeling-Pittsburgh Steel Corporation Retirement Security Plan ("RSP Plan"). The assets of the RSP Plan were merged into the WPC plan as of December 1, 1997. Under the terms of the WHX Pension Plan, the benefit formula and provisions for the WPC and H&H participants continued as they were designed under each of the respective plans prior to the merger.

68

The qualified pension benefits under the WHX Pension Plan were frozen as of December 31, 2005 and April 30, 2006 for hourly and salaried non-bargaining participants, respectively, with the exception of a single operating unit. In 2011, the benefits were frozen for the remainder of the participants. WPC employees ceased to be active participants in the WHX Pension Plan effective July 31, 2003, and as a result, such employees no longer accrue benefits under the WHX Pension Plan.

HNH's subsidiary, JPS Industries Holdings LLC ("JPS"), sponsors a defined benefit pension plan ("JPS Pension Plan"). Under the JPS Pension Plan, substantially all JPS employees who were employed prior to April 1, 2005 have benefits. The JPS Pension Plan was frozen effective December 31, 2005. Employees no longer earned additional benefits after that date. Benefits earned prior to December 31, 2005 will be paid out to eligible participants following retirement. The JPS Pension Plan was "unfrozen" for employees who were active employees on or after June 1, 2012. This new benefit, calculated based on years of service and a capped average salary, will be added to the amount of any pre-2005 benefit. The JPS Pension Plan was again frozen for all future accruals effective December 31, 2015, although unvested participants may still vest in accrued but unvested benefits.

Pension benefits under the WHX Pension Plan are based on years of service and the amount of compensation earned during the participants' employment. However, as noted above, the qualified pension benefits have been frozen for all participants.

Pension benefits for the WPC bargained participants include both defined benefit and defined contribution features, since the plan includes the account balances from the RSP Plan. The gross benefit, before offsets, is calculated based on years of service and the benefit multiplier under the plan. The net defined benefit pension plan benefit is the gross amount offset for the benefits payable from the RSP Plan and benefits payable by the Pension Benefit Guaranty Corporation from previously terminated plans. Individual employee accounts established under the RSP Plan are maintained until retirement. Upon retirement, participants who are eligible for the WHX Pension Plan and maintain RSP Plan account balances will normally receive benefits from the WHX Pension Plan. When these participants become eligible for benefits under the WHX Pension Plan, their vested balances in the RSP Plan become assets of the WHX Pension Plan. Although these RSP Plan assets cannot be used to fund any of the net benefit that is the basis for determining the defined benefit plan's net benefit obligation at the end of the year, the Company has included the amount of the RSP Plan accounts of $13,261 and $14,800 on a gross-basis as both assets and liabilities of the plan as of December 31, 2018 and 2017, respectively.

On December 30, 2016, the WHX Pension Plan was split into two plans by spinning off certain plan participants with smaller benefit obligations (which in the aggregate were equal to approximately 3.0% of the assets of the WHX Pension Plan), and assets equal thereto, to a new separate plan, the WHX Pension Plan II. The benefits of participants under the WHX Pension Plan II are equal to their accrued benefits under the benefit formula that was applicable to each participant under the WHX Pension Plan at the time of the plan spin-off. The total benefit liabilities of the two plans after the spin-off were equal to the benefit liabilities of the WHX Pension Plan immediately before the spin-off, and under the applicable spin-off rules, the WHX Pension Plan II was considered fully funded as of the date of the spin-off.

Net actuarial losses for the WHX Pension Plan are being amortized over the average future lifetime of the participants, which is expected to be approximately 17 years, and for the JPS Plan, 15 years. The Company believes that use of the future lifetime of the participants is appropriate because the plans are inactive.

API Plan

The Company's subsidiary, API, maintains a pension plan in the United Kingdom ("API Plan"). The API Plan is a defined benefit pension plan providing benefits based on final pensionable earnings, as defined in the API Plan, funded by the payment of contributions to a separately administered trust fund. Benefits under the API Plan were frozen, and the plan was closed to new participants in December 2008.

Certain employees of API's former Rahway, New Jersey plant participated in a multiemployer pension plan. For the year ended December 31, 2017, API recorded a one-time charge of $4,300 related to pension obligations associated with the closure of the Rahway, New Jersey plant, which charge is not included in the table below.

The following table presents the components of pension expense for the HNH and API pension plans:

69

	Year Ended December 31,
	2018			2017
Interest cost	$	20,999		$	21,910
Expected return on plan assets	(27,703		)	(25,969		)
Amortization of actuarial loss	9,888			9,228
Total	$	3,184		$	5,169

Actuarial assumptions used to develop the components of pension expense were as follows:

	2018		2017
Discount rates:
WHX Pension Plan	3.45	%	3.84	%
WHX Pension Plan II	3.33	%	3.64	%
JPS Pension Plan	3.40	%	3.81	%
API Pension Plan	2.50	%	2.65	%
HNH expected return on assets	6.50	%	6.50	%
API expected return on assets	3.80	%	3.87	%

The measurement date for plan obligations is December 31. The discount rate is the rate at which the plans' obligations could be effectively settled and is based on high quality bond yields as of the measurement date.

Summarized below is a reconciliation of the funded status for HNH's and API's qualified defined benefit pension plans:

The weighted average assumptions used in the valuations at December 31 were as follows:

	2018		2017
Discount rates:
WHX Pension Plan	4.10	%	3.45	%
WHX Pension Plan II	4.00	%	3.33	%

Pretax amounts included in Accumulated other comprehensive loss at December 31, 2018 and 2017 were as follows:

	HNH Plans				API Plan
	2018		2017		2018		2017
Prior service cost	$	—	$	—	$	2,475	$	—
Net actuarial loss	220,778		254,599		5,551		7,083
Accumulated other comprehensive loss	$	220,778	$	254,599	$	8,026	$	7,083

The pretax amount of actuarial losses included in Accumulated other comprehensive loss at December 31, 2018 that is expected to be recognized in net periodic benefit cost in 2019 is $10,075.

Other pretax changes in plan assets and benefit obligations recognized in comprehensive income (loss) are as follows:

	HNH Plans					API Plan
	Pension Benefits					Pension Benefits
	2018		2017			2018			2017
Current year actuarial gain (loss)	$	23,933	$	(24,333	)	$	1,300		$	6,339
Amortization of actuarial loss	9,888		9,228			—			—
Current year prior service cost	—		—			(2,634		)	—
Amortization of prior service credit	—		—			24			—

Total recognized in comprehensive income (loss)	$	33,821	$	(15,105	)	$	(943	)	$	6,339

The actuarial gain in 2018 occurred principally because the discount rates used to measure benefit obligations for the HNH plans at the end of the fiscal year increased from the prior fiscal year end. In addition, the mortality assumptions were updated to reflect the results of a mortality study conducted in 2018, which also created an actuarial gain. Conversely, the actuarial loss in 2017 occurred principally because the discount rates used to measure benefit obligation for the HNH plans decreased in that year.

Benefit obligations were in excess of plan assets for each of the pension plans at both December 31, 2018 and 2017. Additional information for the plans with accumulated benefit obligations in excess of plan assets follows:

	HNH Plans				API Plan
	2018		2017		2018		2017
Projected benefit obligation	$	498,812	$	601,194	$	135,612	$	152,006
Accumulated benefit obligation	$	498,812	$	601,194	$	135,612	$	152,006
Fair value of plan assets	$	308,489	$	349,819	$	125,833	$	140,634

In determining the expected long-term rate of return on plan assets, the Company evaluated input from various investment professionals. In addition, the Company considered its historical compound returns, as well as the Company's forward-looking expectations. The Company determines its actuarial assumptions for its pension plans each year to calculate liability information as of December 31, and pension expense or income for the following year. The discount rate assumption is derived from the rate of return on high-quality bonds as of December 31 of each year.

The Company's investment policy is to maximize the total rate of return with a view to long-term funding objectives of the pension plans to ensure that funds are available to meet benefit obligations when due. Pension plan assets are diversified to the extent necessary to minimize risk and to achieve an optimal balance between risk and return. There are no target allocations. The HNH plans' assets are diversified as to type of assets, investment strategies employed and number of investment managers used. Investments may include equities, fixed income, cash equivalents, convertible securities and private investment funds. Derivatives may be used as part of the investment strategy. The Company may direct the transfer of assets between investment managers in order to rebalance the portfolio in accordance with asset allocation guidelines established by the Company.

The fair value of pension investments is defined by reference to one of three categories (Level 1, Level 2 or Level 3) based on the reliability of inputs, as such terms are defined in Note 2 - "Summary of Significant Accounting Policies." HNH's plans' assets at December 31, 2018 and 2017, by asset category, are as follows:

(1) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy.

(2) Hedge funds and common trust funds are comprised of shares or units in commingled funds that may not be publicly traded. The underlying assets in these funds are primarily publicly traded equity securities and fixed income securities.

(3) The limited partnership is a direct lending private debt fund, which serves as an alternative source of liquidity for the shipping industry.

(4) The limited partnership's strategy is to build a concentrated portfolio of 8-10 companies with $100 to $1,000 of equity allocated per investment. Investments will be control positions of minority stakes with significant protections and influence. The strategy will focus on the North American and Asian financial, industrial, energy, consumer and business service sectors.

(5) The limited partnership operates as a fund of funds. The underlying assets in this fund are generally expected to be illiquid. The limited partnership's investment strategy is to seek above-average rates of return and long-term capital growth by investing in a broad range of investments, including, but not limited to, global distressed corporate securities, activist equities, value equities, post-reorganizational equities, municipal bonds, high yield bonds, leveraged loans, unsecured debt, collateralized debt obligations, mortgage-backed securities, commercial mortgage-backed securities, direct lending and sovereign debt.

(6) The offshore feeder fund's Pan-Asia strategy employs a value-oriented and concentrated approach with a long-term horizon and seeks to build a portfolio of independent long and short positions with access to small/mid-cap opportunities.

(7) The JPS Pension Plan holds a deposit administration group annuity contract with an immediate participation guarantee from Transamerica Life Insurance Company ("TFLIC"). The TFLIC contract unconditionally guarantees benefits to certain salaried JPS Pension Plan participants earned through June 30, 1984 in the pension plan of a predecessor employer. The assets deposited under the contract are held in a separate custodial account ("TFLIC Assets"). If the TFLIC Assets decrease to the level of the trigger point (as defined in the contract), which represents the guaranteed benefit obligation representing the accumulated plan benefits as of June 30, 1984, TFLIC has the right to cause annuities to be purchased for the individuals covered by these contract agreements. No annuities have been purchased for the individuals covered by these contract arrangements.

API's pension plan's assets at December 31, 2018 and 2017 by asset category, are as follows:

(1) Represents investments in pooled funds. This is a method of investing whereby a portfolio of assets is built with the objective of moving in-line with liabilities. The assets are typically derivative instruments based on government bonds or instruments called swaps which are exposed to the same liability sensitivities (interest rates and inflation) as the pension liabilities.

During 2018, there were no changes to the HNH plans' Level 3 assets, and during 2017, the changes were as follows:

Contributions

Employer contributions consist of funds paid from employer assets into a qualified pension trust account. HNH's funding policy is to contribute annually an amount that satisfies the minimum funding standards of the Employee Retirement Income Security Act. API's funding policy is to contribute monthly an amount that satisfies the API Plan's provisions to meet the level of assets needed to pay benefits in accordance with the statutory funding objectives required in the United Kingdom.

HNH expects to have required minimum annual contributions for 2019, 2020, 2021, 2022, 2023 and for the five years thereafter of $33,400, $34,700, $34,000, $36,700, $28,500 and $23,700, respectively. API expects to have required minimum annual contributions of $887 for 2019, 2020, 2021 and 2022, and $739 in 2023. Required future pension contributions are estimated based upon assumptions such as discount rates on future obligations, assumed rates of return on plan assets and legislative changes. Actual future pension costs and required funding obligations will be affected by changes in the factors and assumptions described in the previous sentence, as well as other changes such as any plan termination or other acceleration events.

Benefit Payments

Estimated future benefit payments for the pension plans over the next ten years are as follows:

Years	HNH Plans		API Plan
2019	$	42,260	$	5,362
2020	41,305		5,591
2021	40,264		5,844
2022	39,215		6,110
2023	38,151		6,402
2024-2028	171,699		36,117

15. CAPITAL AND ACCUMULATED OTHER COMPREHENSIVE LOSS

As of December 31, 2018, the Company had 25,294,003 Class A units (regular common units) outstanding.

Common Unit Repurchase Program

In December 2016, the Board of Directors of SPH GP approved the repurchase of up to an aggregate of 2,000,000 of the Company's common units. In November 2018, the Board of Directors approved the repurchase of up to an additional 1,000,000 of the Company's common units (collectively, with the December 2016 approval, "Repurchase Program"). The Repurchase Program supersedes and cancels, to the extent any amounts remain available, all previously approved repurchase programs. Any purchases made under the Repurchase Program will be made from time to time on the open market at prevailing market prices or in negotiated transactions off the market, in compliance with applicable laws and regulations. In connection with the Repurchase Program, the Company may enter into a stock purchase plan. The Repurchase Program has no termination date. The Company has purchased 1,583,841 common units for an aggregate price of approximately $27,160 under the Repurchase Program.

Incentive Award Plan

76

On May 24, 2018, the Company's unitholders approved the adoption of the Company's 2018 Incentive Award Plan ("2018 Plan"). The 2018 Plan provides equity-based compensation through the grant of options to purchase the Company's limited partnership units, unit appreciation rights, restricted units, phantom units, substitute awards, performance awards, other unit-based awards, and includes, as appropriate, any tandem distribution equivalent rights granted with respect to an award (collectively, "LP Units"). The 2018 Plan allows for issuance of up to 500,000 LP Units. As of December 31, 2018, no awards had been granted under the 2018 Plan.

Common Unit Dividend

On January 13, 2017, the Company paid dividends of approximately $3,923 to common unitholders of record as of January 3, 2017, excluding a consolidated affiliate. This special one-time cash dividend of $0.15 per common unit was declared on December 22, 2016. Any future determination to declare dividends on its common units will remain at the discretion of the Company's Board of Directors and will be dependent upon a number of factors, including the Company's results of operations, cash flows, financial position and capital requirements, among others.

Preferred Units

The 6.0% Series A preferred units, no par value ("SPLP Preferred Units"), which were issued in connection with the Steel Excel Inc. ("Steel Excel"), HNH and WebFinancial Holding Corporation ("WFHC") transactions discussed below, entitle the holders to a cumulative quarterly cash or in-kind (or a combination thereof) distribution. The Company declared cash distributions of approximately $11,750 and $4,700 to preferred unitholders for the years ended December 31, 2018 and 2017, respectively. The SPLP Preferred Units have a term of nine years and are redeemable at any time at the Company's option at a $25 liquidation value per unit, plus any accrued and unpaid distributions (payable in cash or SPLP common units, or a combination of both, at the Company's discretion). If redeemed in common units, the number of common units to be issued will be equal to the liquidation value per unit divided by the volume weighted-average price of the common units for 60 days prior to the redemption. In addition, the holders can require the Company to repurchase up to 1,600,000 of the SPLP Preferred Units, in cash on a pro rata basis, on the third anniversary of the original issuance date of February 7, 2017, reduced by any preferred units called for redemption by the Company, in cash on a pro rata basis, prior to that time.

The SPLP Preferred Units have no voting rights, except that holders of the preferred units have certain voting rights in limited circumstances relating to the election of directors following the failure to pay six quarterly distributions. The SPLP Preferred Units are recorded as a non-current liability, including accrued interest expense, on the Company's consolidated balance sheets as of December 31, 2018 and 2017 because they have an unconditional obligation to be redeemed for cash or by issuing a variable number of SPLP common units for a monetary value that is fixed and known at inception. Because the SPLP Preferred Units are classified as a liability, distributions thereon are recorded as a component of Interest expense in the Company's consolidated statements of operations. As of December 31, 2018 and 2017, there were 7,927,288 and 7,952,660 SPLP Preferred Units outstanding, respectively.

Steel Excel Transaction

On December 23, 2016, the Company entered into an Amended Agreement and Plan of Merger with a subsidiary of the Company and Steel Excel to make a tender offer to purchase any and all of the outstanding shares of common stock of Steel Excel not already owned by the Company or any of its affiliates. In exchange for each share of Steel Excel common stock, the Company offered 0.712 SPLP Preferred Units. The offer commenced on January 9, 2017 and expired on February 6, 2017. As a result of the completion of the offer, the Company issued approximately 2,500,000 SPLP Preferred Units with a fair value and liquidation value of $25.00 per SPLP Preferred Unit, or approximately $63,500, to Steel Excel shareholders and paid approximately $2,100 in cash for any remaining unvested restricted shares of Steel Excel. As a result of this transaction, the Company owns 100% of Steel Excel.

HNH Transaction

On June 26, 2017, the Company entered into an Agreement and Plan of Merger with a subsidiary of the Company and HNH to make a tender offer to purchase any and all of the outstanding shares of common stock of HNH not already owned by the Company or any of its affiliates. In exchange for each share of HNH common stock, the Company offered 1.484 SPLP Preferred Units. The offer expired on October 12, 2017, and as a result of the completion of the offer, the Company issued approximately 5,400,000 SPLP Preferred Units with a fair value of approximately $112,000 and liquidation value of approximately $135,000 to HNH shareholders. As a result of this transaction, the Company owns 100% of HNH.

WFHC Transactions

77

During 2018, the Company entered into purchase agreements with minority stockholders of its subsidiary, WFHC, pursuant to which the Company purchased shares of common and preferred stock of WFHC in exchange for aggregate consideration totaling approximately $20,680, comprised of cash of $13,708, 185,407 SPLP common units and 186,271 SPLP Preferred Units. As a result of these transactions, the Company now owns 100% of WFHC, as compared to 91.2% at December 31, 2017.

For each of the Steel Excel, HNH and WFHC transactions described above, in accordance with the accounting standard on consolidation, changes in a parent's ownership interest where the parent retains a controlling financial interest in its subsidiary were accounted for as equity transactions. The carrying amount of the acquired noncontrolling interests were eliminated to reflect the change in SPLP's ownership interest in each subsidiary, and the difference between the fair value of the consideration paid and the amount by which the noncontrolling interest was adjusted was recognized in Partners' capital.

iGo Transaction

On December 31, 2018, the Company entered into a contribution agreement with iGo, an equity method investee of the Company, in which the Company contributed its interest in its subsidiary, Kasco LLC ("Kasco"), in exchange for consideration consisting of 5,000,000 newly issued common shares of iGo and the assumption by iGo/Kasco of $15,000 of debt outstanding under the Credit Agreement (see Note 12 - "Long-Term Debt"). As a result of this transaction, the Company now owns 80.2% of iGo's common stock, and iGo became a consolidated subsidiary. As of December 31, 2018, iGo's assets and liabilities have been included in the Company's consolidated balance sheet, with a related noncontrolling interest of 19.8% of iGo's common stock.

Accumulated Other Comprehensive Loss

(c) For 2017, does not include the net unrealized gain on available-for sale securities of $811, the gain on derivative financial instruments of $55, cumulative translation adjustment gains of $932 and gains from the change in net pension and other post-retirement benefit obligations of $474, which are attributable to noncontrolling interests. For 2018, does not include the net unrealized gain on derivative financial instruments of $26 and cumulative translation adjustment of $(40), which are attributable to noncontrolling interests.

(d) Effective January 1, 2018 upon adoption of ASU 2016-01, a cumulative effect reclassification adjustment was made to remove the net unrealized gains and losses on equity securities from Accumulated other comprehensive loss and reclassify them to Partners' capital.

Incentive Unit Expense

Effective January 1, 2012, SPLP issued to the Manager partnership profits interests in the form of incentive units, a portion of which will be classified as Class C common units of SPLP upon the attainment of certain specified performance goals by SPLP, which are determined as of the last day of each fiscal year. If the performance goals are not met for a fiscal year, no portion of the incentive units will be classified as Class C common units for that year. The number of outstanding incentive units is equal to 100% of the common units outstanding, including common units held by non-wholly-owned subsidiaries. The performance goals and expense related to the classification of a portion of the incentive units as Class C units is measured on an annual basis, but is accrued on a quarterly basis. Accordingly, the expense accrued is adjusted to reflect the fair value of the Class C common units

78

on each interim calculation date. In the event the cumulative incentive unit expense calculated quarterly or for the full year is an amount less than the total previously accrued, the Company records a negative incentive unit expense in the quarter when such over accrual is determined. The expense is recorded in Selling, general and administrative expenses in the Company's consolidated statements of operations. The Company recorded $0 and $9,021 of incentive unit expense for the years ended December 31, 2018 and 2017, respectively.

The following is a reconciliation of the income tax provision computed at the federal statutory rate to the provision for income taxes:

	Year Ended December 31,
	2018			2017
(Loss) income before income taxes and equity method investments	$	(9,422	)	$	40,423

Income tax provision	$	12,559		$	51,299

(a) Represents taxes at statutory rate on losses for which no tax benefit is recognizable by SPLP and certain of its subsidiaries which are taxed as pass-through entities. Such losses are allocable directly to SPLP's unitholders and taxed when realized.

The Act was enacted on December 22, 2017. The income tax effects of changes in tax laws are recognized in the period when enacted. The Act provides for numerous significant tax law changes and modifications with varying effective dates, which include reducing the U.S. federal corporate income tax rate from 35% to 21%, creating a territorial tax system (with a one-time mandatory repatriation tax on previously deferred foreign earnings) and allowing for immediate capital expensing of certain qualified property acquired and placed in service after September 27, 2017 and before January 1, 2023.

In response to the enactment of the Act in late 2017, the U.S. Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 ("SAB 118") to address situations where the accounting is incomplete for certain income tax effects of the Act

79

upon issuance of an entity's financial statements for the reporting period in which the Act was enacted. The measurement period allowed by SAB 118, in which the Company recorded an income tax benefit of $1,896 related to the one-time mandatory repatriation tax, closed during the fourth quarter of 2018. The prospects of supplemental legislation or regulatory processes to address uncertainties that arise because of the Act, or evolving technical interpretations of the tax law, may cause the Company's consolidated financial statements to be impacted in the future. The Company will continue to analyze the effects of the Act as subsequent guidance continues to emerge.

The Act also includes a provision to tax global intangible low-taxed income ("GILTI") of foreign subsidiaries. The FASB Staff Q&A Topic No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election either to recognize deferred taxes for temporary differences that are expected to reverse as GILTI in future years or provide for the tax expense related to GILTI resulting from those items in the year the tax is incurred. We have elected to recognize the resulting tax on GILTI as a period expense in the period the tax is incurred.

Deferred income taxes result from temporary differences in the financial basis and tax basis of assets and liabilities. The amounts shown on the following table represent the tax effect of temporary differences between the consolidated tax return basis of assets and liabilities and the corresponding basis for financial reporting, as well as tax credit and operating loss carryforwards.

	December 31,
	2018			2017
Deferred Tax Assets:
Operating loss carryforwards (a)	$	136,940		$	118,594
Postretirement and postemployment employee benefits	50,306			70,151
Tax credit carryforwards	12,837			13,412
Accrued costs	4,970			4,151
Investment impairments and unrealized losses	6,282			7,325
Inventories	3,536			2,468
Environmental costs	3,299			2,297
Capital loss	8,459			7,968
Allowance for doubtful accounts and loan losses	4,460			1,361
Other	1,427			3,748
Gross deferred tax assets	232,516			231,475
Deferred Tax Liabilities:
Intangible assets	(27,758		)	(33,376		)

Gross deferred tax liabilities	(59,403		)	(84,333		)
Valuation allowance (b)	(79,298		)	(41,138		)
Net deferred tax assets	$	93,815		$	106,004
Classified on the Company's consolidated balance sheets as follows:
Deferred tax assets	$	96,040		$	109,011
Deferred tax liabilities	2,225			3,007
	$	93,815		$	106,004

(a) The ability for certain subsidiaries to utilize net operating losses and other credit carryforwards may be subject to limitation upon changes in control.

(b) Certain subsidiaries of the Company establish valuation allowances when they determine, based on their assessment, that it is more likely than not that certain deferred tax assets will not be fully realized. This assessment is based on, but not limited to, historical operating results, uncertainty in projections of taxable income and other uncertainties that may be specific to a particular business.

At December 31, 2018, the Company's corporate subsidiaries had carryforwards of U.S. federal net operating losses ("NOLs") of approximately $397,046 that expire in 2020 through 2037. In addition, there are federal NOLs that can only be utilized by the corporate subsidiaries that generated the prior year losses, commonly called SRLY NOLs, totaling $199,240, which will expire in 2020 through 2037. The Company has a valuation allowance to reserve its deferred tax asset associated with the SRLY NOLs, and the addition of SRLY NOLs during 2018 from the consolidation of iGo is the principal reason for the increase in the valuation allowance during 2018. There is a capital loss carryforward in the amount of $34,815 that expires in 2021-2022. The deferred tax asset associated with this item has been fully reserved.

80

The Company's corporate subsidiaries have NOLs in foreign jurisdictions totaling $18,054 for which a valuation allowance to reserve the associated deferred tax asset has been established. There are NOLs in various states in which the subsidiaries operate. The amount totaled $21,213 and expires in 2019 through 2037. A valuation allowance has been established against a significant portion of the deferred tax asset associated with the state NOLs.

The Company's corporate subsidiaries have federal research and development credit carryforwards of $28,213 that expire in 2019 through 2029, and state research and development credit carryforwards of $20,683 for which a significant amount do not expire. The Company has a valuation allowance to reserve a significant portion of its deferred tax assets associated with the credit carryforwards.

At December 31, 2017, a valuation allowance was released against substantially all of one of the Company's corporate subsidiary's federal deferred tax assets (except for certain federal NOLs of a subsidiary company subject to limitations and the realized capital losses) as the Company concluded such assets were fully realizable. This assessment was primarily based on the restructuring of several business units that enabled operational efficiencies resulting in a more likely than not assertion to realize the majority of the federal deferred tax assets. The Company will continue to monitor the likelihood that it will be able to recover the deferred tax assets in the future. This determination includes objectively verifiable positive evidence that outweighs potential negative evidence.

Unrecognized Tax Benefits

U.S. GAAP provides that the tax effects from an uncertain tax position can be recognized in the consolidated financial statements only if the position is more likely than not of being sustained on audit, based on the technical merits of the position. The change in the amount of unrecognized tax benefits for 2018 and 2017 was as follows:

Balance at December 31, 2016	$	29,394
Additions for tax positions related to current year	32,684
Reductions due to lapsed statutes of limitations	(1,350		)
Balance at December 31, 2017	$	60,728
Additions for tax positions related to current year	977
Additions for tax positions related to prior years	1,413
Payments	(543		)
Reductions due to lapsed statutes of limitations and expiration of credits	(10,850		)
Balance at December 31, 2018	$	51,725

The Company's total gross unrecognized tax benefits were $51,725 and $60,728 at December 31, 2018 and 2017, respectively, of which $33,812, if recognized, would affect the provision for income taxes. In 2018, the Company settled certain state tax examinations resulting in a payment against the reserve of $543. In addition, the Company reversed $10,850 of reserves upon the expiration of the statutes of limitations with applicable taxing authorities and the expiration of time for utilizing certain credits for which a full reserve is maintained. The increase in unrecognized tax benefits in 2017 was primarily related to certain tax credits from prior years that may not be sustained on a more-likely-than-not basis. As of December 31, 2018, it is reasonably possible that unrecognized tax benefits may decrease by $1,103 in the next 12 months due to the expiration of statutes of limitations. The Company recognizes interest and penalties (if applicable) related to uncertain tax positions in its income tax provision in the consolidated statement of operations. For 2018 and 2017, the amount of such interest and penalties recognized was not significant.

The Company is subject to U.S. federal income tax, as well as income taxes in various domestic states and foreign jurisdictions in which the Company operated or formerly operated in. The Company is generally no longer subject to federal, state or local income tax examinations by tax authorities for any year prior to 2015, except as noted below. However, NOLs generated in prior years are subject to examination and potential adjustment by the taxing authorities upon their utilization in subsequent years' tax returns.

A corporate subsidiary of the Company is currently under examination by the Internal Revenue Service ("IRS") for the year 2015, which remains on-going. To date, the IRS has not notified the Company of any material adjustments resulting from the examination. With respect to the same corporate subsidiary, the IRS completed the examination for the year 2014, resulting in no adjustments to the original filing. The Company also settled an IRS examination of a corporate subsidiary's final pre-acquisition period filing, resulting in a small refund.

During 2018, the Company settled various state and local examinations for the years 2012, 2013 and 2015 at a total cost of $543, for which the Company was fully reserved. In addition, certain corporate subsidiaries are either currently under examination or have been notified of pending examinations for the years 2014 through 2016 by the State of New York.

81

The Company is not currently under tax examination in any foreign jurisdictions.

17. NET (LOSS) INCOME PER COMMON UNIT

The following data was used in computing net (loss) income per common unit shown in the Company's consolidated statements of operations:

82

	Year Ended December 31,
	2018			2017
Net (loss) income	$	(31,490	)	$	6,012
Net loss attributable to noncontrolling interests in consolidated entities	(1,114		)	(6,028		)
Net loss attributable to common unitholders	$	(32,604	)	$	(16	)
Net loss per common unit - basic and diluted
Net loss attributable to common unitholders	$	(1.25	)	$	—
Denominator for net loss per common unit - basic and diluted	25,984,185			26,053,098

For the year ended December 31, 2018, the diluted net loss per unit calculation was based on the basic weighted-average units only since the impact of 12,240,672 of SPLP Preferred Units and 24,100 of unvested restricted stock units, would have been anti-dilutive. For the year ended December 31, 2017, the diluted net loss per unit calculation was based on the basic weighted-average units only since the impact of 307,448 incentive units, 4,738,844 of SPLP Preferred Units and 39,634 of unvested restricted stock units, would have been anti-dilutive.

18. FAIR VALUE MEASUREMENTS

Financial assets and liabilities measured at fair value on a recurring basis in the Company's consolidated financial statements as of December 31, 2018 and 2017 are summarized by type of inputs applicable to the fair value measurements as follows:

(a) For additional detail of the marketable securities and long-term investments see Note 10 - "Investments."

There were no transfers of securities among the various measurement input levels during the years ended December 31,

2018 or 2017.

The fair value of the Company's financial instruments, such as cash and cash equivalents, trade and other receivables and accounts payable, approximates carrying value due to the short-term maturities of these assets and liabilities. Carrying cost approximates fair value for long-term debt, which has variable interest rates.

The precious metal and commodity inventories associated with the Company's fair value hedges (see Note 13 - "Financial Instruments") are reported at fair value. Fair values of these inventories are based on quoted market prices on commodity exchanges and are considered Level 1 measurements. The derivative instruments that the Company purchases in connection with its precious metal and commodity inventories, specifically commodity futures and forward contracts, are also valued at fair value. The futures contracts are Level 1 measurements since they are traded on a commodity exchange. The forward contracts are entered into with a counterparty and are considered Level 2 measurements.

Following is a summary of changes in financial assets measured using Level 3 inputs:

	Long-Term Investments
	Investments in Associated Companies (a)		STCN Warrants (a)			Marketable Securities and Other (b)			Total

(a) Unrealized gains and losses are recorded in Loss (income) of associated companies, net of taxes in the Company's consolidated statements of operations.

(b) Realized gains and losses on sale are recorded in Realized and unrealized losses (gains) on securities, net or Revenue in the Company's consolidated statements of operations, as are unrealized gains and losses incurred in 2018. In 2017, prior to the adoption of ASU 2016-01, unrealized gains and losses were recorded in AOCI.

Long-Term Investments - Valuation Techniques

The Company estimates the value of its investment in STCN preferred stock using a Monte Carlo simulation. Key inputs in this valuation include the trading price and volatility of STCN's common stock, the risk-free rate of return, as well as the dividend rate, conversion price and redemption date of the preferred stock. The Company estimates the value of another of its investments in an associated company primarily using a discounted cash flow method adjusted for additional information related to debt covenants, solvency issues and other related matters.

Marketable Securities and Other - Valuation Techniques

The Company uses the net asset value included in quarterly statements it receives in arrears from a venture capital fund to determine the fair value of such fund and determines the fair value of certain corporate securities and corporate obligations by incorporating and reviewing prices provided by third-party pricing services based on the specific features of the underlying securities. The fair value of the derivatives held by WebBank (see Note 13 - "Financial Instruments") represent the estimated amounts that WebBank would receive or pay to terminate the contracts at the reporting date and is based on discounted cash flows analyses that consider credit, performance and prepayment. Unobservable inputs used in the discounted cash flow analyses are: a constant prepayment rate of 7.01% to 35.85%, a constant default rate of 1.01% to 27.56% and a discount rate of 1.34% to 27.71%.

84

Assets Measured at Fair Value on a Nonrecurring Basis

The Company's non-financial assets and liabilities measured at fair value on a non-recurring basis include goodwill and other intangible assets, any assets and liabilities acquired in a business combination, or its long-lived assets written down to fair value. To measure fair value for such assets and liabilities, the Company uses techniques including an income approach, a market approach and/or appraisals (Level 3 inputs). The income approach is based on a discounted cash flow analysis and calculates the fair value by estimating the after-tax cash flows attributable to an asset or liability and then discounting the after-tax cash flows to a present value using a risk-adjusted discount rate. Assumptions used in the discounted cash flow analysis ("DCF") require the exercise of significant judgment, including judgment about appropriate discount rates and terminal values, growth rates and the amount and timing of expected future cash flows. The discount rates, which are intended to reflect the risks inherent in future cash flow projections, used in the DCF are based on estimates of the weighted-average cost of capital of a market participant. Such estimates are derived from analysis of peer companies and consider the industry weighted-average return on debt and equity from a market participant perspective. A market approach values a business by considering the prices at which shares of capital stock, or related underlying assets, of reasonably comparable companies are trading in the public market or the transaction price at which similar companies have been acquired. If comparable companies are not available, the market approach is not used.

19. COMMITMENTS AND CONTINGENCIES

Operating Lease Commitments

The Company has certain facilities under non-cancelable operating lease arrangements. Rent and related expenses recognized in the Company's consolidated statements of operations for the years ended December 31, 2018 and 2017 was $18,945 and $17,895, respectively. Future minimum operating lease and rental commitments under non-cancelable operating leases for SPLP consolidated operations are as follows:

Payments due by period	Amount
2019	$	14,280
2020	11,131
2021	8,975
2022	6,174
2023	3,863
Thereafter	17,867
Total	$	62,290

Environmental and Litigation Matters

As discussed in more detail below, certain of the Company's subsidiaries have been designated as potentially responsible parties ("PRPs") by federal and state agencies with respect to certain sites with which they may have had direct or indirect involvement and as defendants in certain litigation matters. Most such legal proceedings and environmental investigations involve unspecified amounts of potential damage claims or awards, are in an initial procedural phase, involve significant uncertainty as to the outcome or involve significant factual issues that need to be resolved, such that it is not possible for the Company to estimate a range of possible loss. For matters that have progressed sufficiently through the investigative process such that the Company is able to reasonably estimate a range of possible loss, an estimated range of possible loss is provided, in excess of the accrued liability (if any) for such matters. Any estimated range is or will be based on currently available information and involves elements of judgment and significant uncertainties. Any estimated range of possible loss may not represent the Company's maximum possible loss exposure. The circumstances of such legal proceedings and environmental investigations will change from time to time, and actual results may vary significantly from the current estimate. For current proceedings not specifically reported below, management does not anticipate that the liabilities, if any, arising from such proceedings would have a material effect on the financial position, liquidity or results of operations of the Company.

The environmental claims are in various stages of administrative or judicial proceedings and include demands for recovery of past governmental costs, and for future investigations and remedial actions. In many cases, the dollar amounts of the claims have not been specified and, with respect to a number of the PRP claims, have been asserted against a number of other entities for the same cost recovery or other relief as was asserted against certain of the Company's subsidiaries. The Company accrues costs associated with environmental and litigation matters on an undiscounted basis, when they become probable and reasonably estimable. As of December 31, 2018, on a consolidated basis, the Company has recorded liabilities of $14,960 in Accrued liabilities on the consolidated balance sheet, which represent the current estimate of environmental remediation liabilities as well as reserves

85

related to the litigation matters discussed below. Expenses relating to these costs, and any recoveries, are included in Selling, general and administrative expenses in the Company's consolidated statements of operations. In addition, the Company has insurance coverage available for several of these matters and believes that excess insurance coverage may be available as well. Estimates of the Company's liability for remediation of a particular site and the method and ultimate cost of remediation require a number of assumptions that are inherently difficult to make, and the ultimate outcome may be materially different from current estimates.

Environmental Matters

Certain HNH subsidiaries have existing and contingent liabilities relating to environmental matters, including costs of remediation, capital expenditures, and potential fines and penalties relating to possible violations of national and state environmental laws. Those subsidiaries have remediation expenses on an ongoing basis, although such costs are continually being readjusted based upon the emergence of new techniques and alternative methods. HNH recorded liabilities of approximately $13,211 related to estimated environmental remediation costs as of December 31, 2018. HNH may have insurance coverage available for certain of these matters.

Included among these liabilities, certain HNH subsidiaries have been identified as PRPs under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") or similar state statutes at sites and are parties to administrative consent orders in connection with certain properties. Those subsidiaries may be subject to joint and several liabilities imposed by CERCLA on PRPs. Due to the technical and regulatory complexity of remedial activities and the difficulties attendant in identifying PRPs and allocating or determining liability among them, the subsidiaries are unable to reasonably estimate the ultimate cost of compliance with such laws.

Based upon information currently available, the HNH subsidiaries do not expect that their respective environmental costs, including the incurrence of additional fines and penalties, if any, will have a material adverse effect on them or that the resolution of these environmental matters will have a material adverse effect on the financial position, results of operations or cash flows of such subsidiaries or the Company, but there can be no such assurances. The Company anticipates that the subsidiaries will pay any such amounts out of their respective working capital, although there is no assurance that they will have sufficient funds to pay them. In the event that a HNH subsidiary is unable to fund its liabilities, claims could be made against its respective parent companies for payment of such liabilities.

The sites where certain HNH subsidiaries have environmental liabilities include the following:

HNH has been working with the Connecticut Department of Energy and Environmental Protection ("CTDEEP") with respect to its obligations under a 1989 consent order that applies to a property in Connecticut that HNH sold in 2003 ("Sold Parcel") and an adjacent parcel ("Adjacent Parcel") that together comprise the site of a former HNH manufacturing facility. The remaining remediation, monitoring and regulatory administrative costs for the Sold Parcel are expected to approximate $100. With respect to the Adjacent Parcel, an ecological risk assessment has been completed and the results, along with proposed cleanup goals, were submitted in the second quarter of 2016 to the CTDEEP for their review and approval. An upland work plan to investigate the upland portion of the parcel was submitted in the third quarter of 2017 to the CTDEEP and was approved in March 2018. That investigation work started in the second quarter of 2018 and was completed in the fourth quarter of 2018. Additional investigatory work could be required dependent upon CTDEEP requirements. Investigation of the wetlands portion is also expected to start in the first half of 2019, pending regulatory approvals and setting goals for the entire parcel. The total remediation costs for the Adjacent Parcel cannot be reasonably estimated at this time. Based on the current stage of the investigation at this time, the Company estimates that it is reasonably possible that it may incur aggregate losses over a period of several years, above its accrued liability, in a range of $2,000 to $6,000. Due to the uncertainties, there can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of the Company.

In 1986, Handy & Harman Electronic Materials Corporation ("HHEM"), a subsidiary of HNH, entered into an administrative consent order ("ACO") with the New Jersey Department of Environmental Protection ("NJDEP") with regard to certain property that it purchased in 1984 in New Jersey. The ACO involves investigation and remediation activities to be performed with regard to soil and groundwater contamination. HHEM is actively remediating the property and is continuing to investigate effective methods for achieving compliance with the ACO. HHEM anticipates entering into discussions with the NJDEP to address that agency's potential natural resource damage claims, the timing and ultimate scope and cost of which cannot be estimated at this time. Pursuant to a settlement agreement with the former owner/operator of the site, the responsibility for site investigation and remediation costs, as well as any other costs, as defined in the settlement agreement, related to or arising from environmental contamination on the property (collectively, "Costs") are contractually allocated 75% to the former owner/operator and 25% jointly to HHEM and HNH, all after having the first $1,000 paid by the former owner/operator. As of December 31, 2018, total investigation

86

and remediation costs of approximately $7,500 and $2,400 have been expended by the former owner/operator and HHEM, respectively, in accordance with the settlement agreement. Additionally, HHEM had been reimbursed indirectly through insurance coverage for a portion of the Costs for which HHEM is responsible. While the primary insurance reimbursement ceased, HHEM believes that there is additional excess insurance coverage, which it is currently pursuing. There is no assurance that the former owner/operator or guarantors will continue to timely reimburse HHEM for expenditures and/or will be financially capable of fulfilling their obligations under the settlement agreement and the guaranties. There is no assurance that there will be any additional insurance reimbursement. A reserve of approximately $1,800 has been established for HHEM's expected 25% share of anticipated costs at this site, which is based upon the recent selection of a final remedy, on-going operations and maintenance, additional investigations and monitored natural attenuation testing over the next 30 years. There can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of HHEM, HNH or the Company.

HNH's subsidiary, SL Industries, Inc. ("SLI"), may incur environmental costs in the future as a result of the past activities of its former subsidiary, SL Surface Technologies, Inc. ("SurfTech"), in Pennsauken, New Jersey ("Pennsauken Site"), in Camden, New Jersey and at its former subsidiary, SGL Printed Circuits in Wayne, New Jersey. At the Pennsauken Site, in 2013, SLI reached an agreement with both the U.S. Department of Justice and the U.S. Environmental Protection Agency ("EPA") related to its liability and entered into a Consent Decree which governs the agreement. SLI has completed the remediation as required by the Consent Decree and has paid EPA a fixed sum for its past oversight costs. Separate from the Consent Decree, in December 2012, the NJDEP made a settlement demand of $1,800 for past and future cleanup and removal costs and natural resource damages ("NRD"). To avoid the time and expense of litigating the matter, SLI offered to pay approximately $300 to fully resolve the claim presented by the State of New Jersey ("State"). SLI's settlement offer was rejected. On December 6, 2018, the State filed a complaint against SLI related to its operations at the Pennsauken Site. The State is seeking treble damages and attorneys' fees, NRD for loss of use of groundwater, as well as a request for relief that SLI pay all cleanup and removal costs that the State has incurred and will incur at the Pennsauken Site. While the State did not specifically identify its alleged damages in the complaint, the State has identified $3,661 in past costs through December 11, 2018. SLI intends to assert all legal and procedural defenses available to it. Although the final scope and cost of this claim cannot be verified at this time, we estimate that it is reasonably possible that we may incur an aggregate loss in a range of $300 to $3,661. Given the State's other generally-alleged damages, however, there can be no assurance that there will not be potential additional costs associated with the Pennsauken Site, which cannot be reasonably estimated at this time. Accordingly, there can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of SLI, HNH or the Company.

SLI reported soil contamination and a groundwater contamination in 2003 from the SurfTech site located in Camden, New Jersey. Substantial investigation and remediation work has been completed under the direction of the Licensed Site Remediation Professional ("LSRP") for the site. Additional remediation initiated during the fourth quarter of 2018 is expected to continue into the first quarter of 2019 and post-remediation groundwater monitoring conducted thereafter. A full-scale groundwater bioremediation is expected to be implemented during the first quarter of 2019 following the remediation mentioned above. A reserve of $2,500 has been established for anticipated costs at this site, but there can be no assurance that there will not be potential additional costs associated with the site which cannot be reasonably estimated at this time. Accordingly, there can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of SLI, HNH or the Company.

SLI is currently participating in environmental assessment and cleanup at a commercial facility located in Wayne, New Jersey. Contaminated soil and groundwater has undergone remediation with the NJDEP and LSRP oversight, but contaminants of concern in groundwater and surface water, which extend off-site, remain above applicable NJDEP remediation standards. A reserve of approximately $1,100 has been established for anticipated costs, but there can be no assurance that there will not be potential additional costs associated with the site, which cannot be reasonably estimated at this time. Accordingly, there can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of SLI, HNH or the Company.

BNS LLC, a wholly-owned subsidiary of the BNS Holdings Liquidating Trust, has been named as a PRP at one previously disclosed site. Based upon information currently available, BNS Holdings Liquidating Trust does not expect that its environmental costs or that the resolution of this environmental matter will have a material adverse effect on the financial position, results of operations or cash flows of the Company, and although there can be no such assurances to this effect, the Company will provide further updates as to this site only if that assessment changes.

Litigation Matters

On December 8, 2017, a putative stockholder class action, captioned Sciabacucchi v. DeMarco, et al., was filed in the Court of Chancery of the State of Delaware by a purported former stockholder of HNH challenging the Company's acquisition,

87

through a subsidiary, of all of the outstanding shares of common stock of HNH not already owned by the Company or any of its affiliates. On June 15, 2018, this action was consolidated with a second putative stockholder class action filed April 30, 2018, and captioned John Levin v. DeMarco, et al. The consolidated action names as defendants the former members of the HNH board of directors, the Company and SPH GP, and alleges, among other things, that the defendants breached their fiduciary duties to the former public stockholders of HNH in connection with the aforementioned acquisition. The complaint seeks, among other relief, unspecified monetary damages, attorneys' fees and costs. On July 5, 2018, the Court granted plaintiff's motion for class certification. The Company is vigorously defending itself against these claims; however, the outcome of this matter is uncertain.

A subsidiary of BNS Holdings Liquidating Trust ("BNS Sub") has been named as a defendant in multiple alleged asbestos-related toxic-tort claims filed over a period beginning in 1994 through December 31, 2018. In many cases these claims involved more than 100 defendants. Of the claims settled, the average settlement was less than $3. There remained approximately 30 pending asbestos claims as of December 31, 2018. BNS Sub believes it has significant defenses to any liability for toxic-tort claims on the merits. None of these toxic-tort claims has gone to trial and, therefore, there can be no assurance that these defenses will prevail. BNS Sub has insurance policies covering asbestos-related claims for years beginning 1974 through 1988. BNS Sub annually receives retroactive billings or credits from its insurance carriers for any increase or decrease in claims accruals as claims are filed, settled or dismissed, or as estimates of the ultimate settlement costs for the then-existing claims are revised. As of both December 31, 2018 and 2017, BNS Sub has accrued $1,349 relating to the open and active claims against BNS Sub. This accrual includes the amount of unpaid retroactive billings submitted to the Company by the insurance carriers and also the Company's best estimate of the likely costs for BNS Sub to settle these claims outside the amounts funded by insurance. There can be no assurance that the number of future claims and the related costs of defense, settlements or judgments will be consistent with the experience to-date of existing claims and that BNS Sub will not need to significantly increase its estimated liability for the costs to settle these claims to an amount that could have a material effect on the consolidated financial statements.

In the ordinary course of our business, we are subject to other periodic lawsuits, investigations, claims and proceedings, including, but not limited to, contractual disputes, employment, environmental, health and safety matters, as well as claims associated with our historical acquisitions and divestitures. There is insurance coverage available for many of the foregoing actions. Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations, claims and proceedings asserted against us, we do not believe any currently pending legal proceeding to which we are a party will have a material adverse effect on our business, prospects, financial condition, cash flows, results of operations or liquidity.

22. REGULATORY MATTERS

WebBank is subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain actions by regulators that, if undertaken, could have a direct material effect on WebBank's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, WebBank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. WebBank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

In July 2013, the Federal Deposit Insurance Corporation approved the final rules implementing the Basel Committee on Banking Supervision's capital guidelines for U.S. banks ("Basel III"). Under the final rules, which began for WebBank on January 1, 2015 and have been fully implemented as of January 1, 2019, minimum requirements increased for both the quantity and quality of capital held by WebBank. The rules include a new common equity Tier 1 capital to risk-weighted assets ratio ("CET1 Ratio") of 4.5% and a capital conservation buffer of 2.5% of risk-weighted assets, which as fully phased-in, effectively results in a minimum CET1 Ratio of 7.0%. Basel III raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0% (which, with the capital conservation buffer, effectively results in a minimum Tier 1 capital ratio of 8.5% as fully phased-in), effectively results in a minimum total capital to risk-weighted assets ratio of 10.5% (with the capital conservation buffer fully phased-in), and requires a minimum leverage ratio of 4.0%. Basel III also made changes to risk weights for certain assets and off-balance-sheet exposures. WebBank expects that its capital ratios under Basel III will continue to exceed the well capitalized minimum capital requirements, and such amounts are disclosed in the table below:

					Amount of Capital Required

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

As required by Rule 13a-15(b) under the Exchange Act, we conducted an evaluation under the supervision and with the participation of our management, including the Principal Executive Officer and the Chief Financial Officer, of the effectiveness of our disclosure controls and procedures as of the end of the period covered by this report. Based on that evaluation, the Principal Executive Officer and the Chief Financial Officer concluded that as of December 31, 2018 our disclosure controls and procedures are effective in ensuring that all information required to be disclosed in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that such information is accumulated and communicated to our management, including our Principal Executive Officer and Chief Financial Officer, in a manner that allows timely decisions regarding required disclosure.

Management's Report on Internal Control Over Financial Reporting

Management of the Company is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rule 13a-15(f) under the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company's consolidated financial statements for external reporting purposes in accordance with U.S. GAAP.

The Company completed the acquisition of Dunmore on February 16, 2018. The Company's management excluded the operations of Dunmore from its evaluation of, and conclusion on, the effectiveness of management's internal control over financial reporting as of December 31, 2018. This business represents approximately 3.2% of the Company's total assets as of December 31, 2018, and approximately 3.8% of the Company's total revenue for the year then ended. The Company's management will fully integrate the operations of Dunmore into its assessment of the effectiveness of its internal control over financial reporting in 2019.

Under the supervision and with the participation of the Company's management, including the Company's Principal Executive Officer and the Chief Financial Officer, the Company conducted an evaluation of the effectiveness of the internal control over financial reporting of the Company as referred to above as of December 31, 2018 as required by Rule 13a-15(c) under the Exchange Act. In making this assessment, the Company used the criteria set forth in the framework in Internal Control - Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its evaluation under the framework in Internal Control - Integrated Framework (2013), management concluded that the Company's internal control over financial reporting was effective as of December 31, 2018.

Deloitte & Touche LLP, the independent registered public accounting firm who audited the Company's 2018 consolidated financial statements included in this Annual Report on Form 10-K, has issued a report on the effectiveness of the Company's internal control over financial reporting as of December 31, 2018, which is included herein.

Changes in Internal Control over Financial Reporting

No change in internal control over financial reporting occurred during the quarter ended December 31, 2018 that has materially affected, or is reasonably likely to materially affect, the Company's internal control over financial reporting.

Inherent Limitations Over Controls

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.

NATURE OF THE BUSINESS AND BASIS OF PRESENTATION

NATURE OF THE BUSINESS AND BASIS OF PRESENTATION

Nature of the Business

Steel Partners Holdings L.P. ("SPLP" or "Company") is a diversified global holding company that engages in multiple businesses through consolidated subsidiaries and other interests. It owns and operates businesses and has significant interests in companies in various industries, including diversified industrial products, energy, defense, supply chain management and logistics, banking and youth sports. SPLP operates through the following segments: Diversified Industrial, Energy, Financial Services, and Corporate and Other, which are managed separately and offer different products and services. For additional details related to the Company's reportable segments see Note 21 - "Segment Information." Steel Partners Holdings GP Inc. ("SPH GP"), a Delaware corporation, is the general partner of SPLP and is wholly-owned by SPLP. The Company is managed by SP General Services LLC ("Manager"), pursuant to the terms of an amended and restated management agreement ("Management Agreement") discussed in further detail in Note 20 - "Related Party Transactions."

Basis of Presentation

The consolidated financial statements include the accounts of the Company and its majority or wholly-owned subsidiaries. All material inter-company accounts and transactions have been eliminated in consolidation. Certain amounts in the Company's 2017 consolidated statements of operations and cash flows have been reclassified to conform to the comparable 2018 presentation.

During the first quarter of 2018, the Company corrected an out-of-period misstatement related to the increase in the fair value of the Company's investment in Steel Connect, Inc. ("STCN") preferred stock for the period from December 15, 2017 to December 31, 2017. Had this correction been recorded at December 31, 2017, the Company's investment in STCN preferred stock would have increased to $46,208 at December 31, 2017, with a corresponding $11,208 increase in Income of associated companies, net of tax and Net income to $28,096 and $17,220, respectively. For the year ended December 31, 2018, the Company's Loss of associated companies, net of taxes and Net loss would have increased to losses of $20,717 and $42,698, respectively. In addition, the Company made a correction as of December 31, 2016, decreasing Accumulated other comprehensive loss by $1,782 and decreasing Partners' capital by the same amount, to properly reflect certain hedging activities associated with a 2015 business combination.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates in Preparation of Consolidated Financial Statements

The Company's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses, and related disclosure of contingent assets and liabilities during the reporting period. The more significant estimates include: (1) the valuation allowances for trade and other receivables, loans receivable and inventories; (2) the valuation of goodwill, indefinite-lived intangible assets, long-lived assets and associated companies; (3) deferred tax assets; (4) environmental liabilities; (5) fair value of derivatives; (6) post-employment benefit liabilities; (7) estimates and assumptions used in the determination of fair value of certain securities; and (8) estimates of loan losses. Actual results may differ from the estimates used in preparing the consolidated financial statements; and, due to substantial holdings in and/or restrictions on certain investments, the value that may be realized could differ from the estimated fair value.

Cash and Cash Equivalents

Cash and cash equivalents include cash and deposits in depository institutions, financial institutions and banks. Cash at December 31, 2018 and 2017 also includes $242,088 and $286,454, respectively, of WebBank cash at the Federal Reserve Bank and in its Federal Funds account at its correspondent banks. The Company considers all highly liquid debt instruments with maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include qualifying money market funds and exclude amounts where availability is restricted by loan agreements or other contractual provisions. Cash equivalents are stated at cost, which approximates market value. There is a significant concentration of cash that, during the periods presented, exceeded the federal deposit insurance limits and exposed the Company to credit risk. SPLP does not anticipate any losses due to this concentration of cash at December 31, 2018.

Restricted Cash

Restricted cash at December 31, 2018 and 2017 primarily represents cash collateral for certain short sales of corporate securities (see Note 13 - "Financial Instruments" for additional information).

Marketable Securities and Long-Term Investments

Marketable securities consist of short-term deposits, corporate debt and equity instruments, and mutual funds. The Company classifies its marketable securities as current assets based on the nature of the securities and their availability for use in current operations. Long-term investments consist of equity securities and certain associated company investments. Held-to-maturity securities are classified in Other non-current assets. SPLP determines the appropriate classifications of its investments at the acquisition date and re-evaluates the classifications at each balance sheet date.

• Since the Company adopted Accounting Standards Update No. ("ASU") 2016-01 effective January 1, 2018, available-for-sale equity securities are now reported at fair value, with unrealized gains and losses recognized in Realized and unrealized losses (gains) on securities, net in the consolidated statement of operations. In 2017, prior to the adoption of ASU 2016-01, such unrealized gains and losses were recognized in Accumulated other comprehensive income (loss) ("AOCI") as a separate component of SPLP's Partners' capital.

• Available-for-sale debt securities are reported at fair value, with unrealized gains and losses recognized in AOCI as a separate component of SPLP's Partners' capital in both 2018 and 2017.

• Associated companies represent equity method investments in companies where our ownership is between 20% and 50% of the outstanding equity and the Company has the ability to exercise influence, but not control, over the investee. For equity method investments where the fair value option has been elected, unrealized gains and losses are reported in the Company's consolidated statements of operations as part of Loss (income) of associated companies, net of tax. For the equity method investments where the fair value option has not been elected, SPLP records the investment at cost and subsequently increases or decreases the investment by its proportionate share of the net income or loss and other comprehensive income or loss of the investee.

• Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts.

Dividend and interest income is recognized when earned. Realized gains and losses on marketable securities and long-term investments are included in earnings and are derived using the specific-identification method. Commission expense is recorded as a reduction of sales proceeds on investment sales. Commission expense on purchases is included in the cost of investments on the Company's consolidated balance sheets.

Other Than Temporary Impairment

If the Company believes a decline in the market value of any available-for-sale debt security, equity method or held-to-maturity security below cost is other than temporary, a loss is charged to earnings, which establishes a new cost basis for the security. Impairment losses are included in Asset impairment charges in the Company's consolidated statements of operations. SPLP's determination of whether a security is other than temporarily impaired incorporates both quantitative and qualitative information. The Company considers a number of factors including, but not limited to, the length of time and the extent to which the fair value has been less than cost, the length of time expected for recovery, the financial condition of the issuer, the reason for the decline in fair value, changes in fair value subsequent to the balance sheet date, the ability and intent to hold investments to maturity, and other factors specific to the individual investment.

Specifically, for held-to-maturity securities, the Company considers whether it plans to sell the security or it is more-likely-than-not that it will be required to sell the security before recovery of its amortized cost. The credit component of an other-than-temporary impairment loss is recognized in earnings and the non-credit component is recognized in AOCI in situations where the Company does not intend to sell the security and it is more likely-than-not that the Company will not be required to sell the security prior to recovery. If there is an other-than-temporary impairment in the fair value of any individual security classified as held-to-maturity, the Company writes down the security to fair value with a corresponding credit loss portion charged to earnings, and the non-credit portion being charged to AOCI. SPLP's assessment involves a high degree of judgment and accordingly, actual results may differ materially from those estimates and judgments.

Trade Receivables and Allowance for Doubtful Accounts

The Company recognizes bad debt expense through an allowance account using estimates based primarily on management's evaluation of the financial condition of the customer, historical experience, credit quality, whether any amounts are currently past due, the length of time accounts may be past due, previous loss history and management's determination of a customer's current ability to pay its obligations. Trade receivable balances are charged off against the allowance when it is determined that the receivables will not be recovered, and payments subsequently received on such receivables are credited to recovery of accounts written off. The Company believes that the credit risk with respect to trade receivables is limited due to this credit evaluation process. As of December 31, 2018, the top 10 of the Company's largest customer balances accounted for 20% of the Company's trade receivables.

Loans Receivable, Including Loans Held for Sale

WebBank's loan activities include several lending arrangements with companies where it originates credit card and other loans for consumers and small businesses. These loans are classified as Loans receivable and are typically sold after origination. As part of these arrangements, WebBank earns fees that are recorded in non-interest income. Fees earned from these lending arrangements are recorded as fee income. WebBank also purchases participations in commercial and industrial loans through loan syndications. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses ("ALLL"), and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield over the estimated life of the loan.

Through a loan program, merchants can borrow a certain percentage of their annual payment volume and are charged a fixed fee for the loan, which targets an annual percentage rate based on the overall credit assessment of the merchant. Loans are repaid through a fixed percentage of the merchant's future payment volume. The fee is fixed at the time the loan is extended. The fixed fee is amortized to interest income based on the amount repaid over the repayment period. We estimate the repayment period based on the merchant's payment processing history. There is no stated interest rate. There is a general requirement that at least 10% of the original amount of the loan plus the fixed fee must be repaid every 90 days. We calculate the repayment rate of the merchant's future payment volume so that repayment of the loan or advance and fixed fee is expected to generally occur within 9 to 12 months from the date of the loan or advance.

Loans held for sale are carried at the lower of cost or estimated market value in the aggregate. A valuation allowance is recorded when cost exceeds fair value based on our determination at the time of reclassification and periodically thereafter. Gains and losses are recorded in noninterest income based on the difference between sales proceeds and carrying value and impairments from reductions in carrying value.

Loans are reported as past due when either principal or interest is due and unpaid for a period of 30 days or more. The accrual of interest on loans is generally discontinued at the time the loan is 90 to 180 days delinquent, depending on the type of loan, unless the loan is well-secured and in process of collection. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful.

All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Loan Impairment and Allowance for Loan Losses

A loan is considered impaired when, based on current information and events, it is probable that WebBank will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments. When a loan has been identified as being impaired, the amount of impairment is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, when appropriate, the loan's observable fair value or the fair value of the collateral (less any selling costs) if the loan is collateral-dependent. If the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest, net of deferred loan fees or costs and unamortized premium or discount), an impairment is recognized by creating or adjusting an existing allocation of the ALLL, or by charging down the loan to its value determined in accordance with U.S. GAAP.

The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when the uncollectability of a loan or receivable balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The ALLL is evaluated on a regular basis and is based upon a periodic review of the collectability of the amounts due in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are classified as doubtful, substandard or loss. For such loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical loss experience and is adjusted for qualitative factors to cover uncertainties that could affect the estimate of probable losses. The ALLL is increased by charges to income and decreased by charge-offs (net of recoveries). The periodic evaluation of the adequacy of the allowance is based on WebBank's past loss experience, known and inherent risks in the portfolio, adverse situations that may affect the debtor's ability to repay, the estimated value of any underlying collateral and current economic conditions.

Inventories

Inventories are generally stated at the lower of cost (determined by the first-in, first-out method or average cost method) or market. Cost is determined by the last-in, first-out ("LIFO") method for certain precious metal inventory held in the U.S., and remaining precious metal inventory is primarily carried at fair value. For precious metal inventory, no segregation among raw materials, work in process and finished products is practicable. For other inventory, the cost of work in process and finished products comprises the cost of raw materials, direct labor and overhead costs attributable to the production of inventory.

Non-precious metal inventories are evaluated for estimated excess and obsolescence based upon assumptions about future demand and market conditions, and are adjusted accordingly. If actual market conditions are less favorable than those projected, future write-downs may be required.

Goodwill and Other Intangible Assets, Net

Goodwill, which is not amortized, represents the difference between the purchase price and the fair value of identifiable net assets acquired in a business combination. Goodwill is reviewed for impairment indicators throughout the year and tested for impairment annually in the fourth quarter. An entity can choose between two testing approaches:

a. Step 0 or Qualitative approach - An entity may assess qualitative factors to determine whether it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount, including goodwill. In evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, an entity should assess relevant events and circumstances. Examples of such events and circumstances would include pertinent macroeconomic conditions, industry and market considerations, overall financial performance and other factors.

An entity has an unconditional option to bypass this qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period.

b. Step 1 or Quantitative approach - The fair value of a reporting unit is calculated and compared with its carrying amount. There are several methods that may be used to estimate a reporting unit's fair value, including the income approach, market approach and/or cost approach. If the fair value of a reporting unit exceeds its carrying amount, there is no indication of impairment and further testing is not required. If the carrying amount of a reporting unit exceeds its fair value, then a second step of testing is required ("Step 2"). The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill.

For 2018, the Company utilized a qualitative approach for all of its reporting units, except for the Packaging business within its Diversified Industrial segment. Based on its qualitative assessment, the Company does not believe that it is more likely than not that the fair value of any of its reporting units tested under this approach is less than its carrying value. The Company performed a quantitative assessment of goodwill associated with its Packaging business due to a decline in market conditions and lower demand for certain of the Packaging business' product lines. The assessment was based on a combination of income and market approaches to estimate the fair value of the reporting unit, which indicated that the fair value of this reporting unit exceeded its carrying value. Significant assumptions used in the discounted cash flow analysis included expected future earnings and cash flows, which are based on management's current expectations, as well as the related risk-adjusted discount rate used to estimate fair value. There were no goodwill impairment charges recorded as a result of these assessments. For 2017, the Company utilized a qualitative approach for all of its reporting units to assess goodwill, and there were no goodwill impairment charges recorded as a result of the assessment.

Other intangible assets with indefinite lives are not amortized, while other intangible assets with finite lives are amortized over their estimated useful lives. Intangible assets with finite lives are reviewed for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable (see "Long-Lived Asset Testing" below).

Intangible assets with indefinite lives, which are only within the Diversified Industrial segment, are tested for impairment at least annually, or when events or changes in circumstances indicate that it is more likely than not that the asset is impaired. Companies can use the same two testing approaches for indefinite-lived intangibles as for goodwill. For 2018 and 2017, the Company utilized a qualitative approach to assess its intangible assets with indefinite lives, and the results indicated no impairment in either of these years.

Derivatives

The Company uses various hedging instruments to reduce the impact of changes in precious metal prices and the effect of foreign currency fluctuations. In accordance with Accounting Standards Codification ("ASC") 815, Derivatives and Hedging, these instruments are recorded as either fair value hedges, economic hedges, cash flow hedges or derivatives with no hedging designation.

Precious Metals

The Company's precious metal and commodity inventories are subject to market price fluctuations. The Company enters into commodity futures and forward contracts to mitigate the impact of price fluctuations on its precious and certain non-precious metal inventories that are not subject to fixed price contracts. The Company's hedging strategy is designed to protect it against normal volatility; therefore, abnormal price changes in these commodities or markets could negatively impact the Company's earnings.

Fair Value Hedges. The fair values of these derivatives are recognized as derivative assets and liabilities on the Company's consolidated balance sheets. The net change in fair value of the derivative assets and liabilities, and the change in the fair value of the underlying hedged inventory, are recognized in the Company's consolidated statements of operations, and such amounts principally offset each other due to the effectiveness of the hedges. The fair value hedges are associated primarily with the Company's precious metal inventory carried at fair value.

Economic Hedges. As these derivatives are not designated as accounting hedges under ASC 815, they are accounted for as derivatives with no hedge designation. The derivatives are marked to market, and both realized and unrealized gains and losses are recorded in current period earnings in the Company's consolidated statements of operations. The economic hedges are associated primarily with the Company's precious metal inventory valued using the LIFO method.

Foreign Currency Forward Contracts

The Company enters into foreign currency forward contracts to hedge certain of its receivables and payables denominated in other currencies. In addition, the Company enters into foreign currency forward contracts to hedge the value of certain of its future sales and the value of its future purchases denominated in other currencies. The forward contracts that are used to hedge the risk of foreign exchange movement on its receivables and payables are accounted for as fair value hedges under ASC 815. The fair values of these derivatives are recognized as derivative assets and liabilities on the Company's consolidated balance sheets. The net change in fair value of the derivative assets and liabilities are recognized in the Company's consolidated statements of operations. The forward contracts that are used to hedge the value of the Company's future sales and purchases are accounted for as cash flow hedges in accordance with ASC 815. These hedges are fully effective and accordingly, the changes in fair value are recorded in AOCI and, at maturity, any gain or loss on the forward contract is reclassified from AOCI into the Company's consolidated statements of operations.

WebBank - Derivative Financial Instruments

WebBank's derivative financial instruments represent on-going economic interests in loans made after they are sold. These derivatives are carried at fair value on a gross basis in Other non-current assets on the Company's consolidated balance sheet. Gains and losses resulting from changes in fair value of these derivative instruments are accounted for in the Company's consolidated statements of operations in Financial services revenue. Fair value represents the estimated amounts that WebBank would receive at the reporting date based on a discounted cash flow model for the same or similar instruments. WebBank does not enter into derivative contracts for speculative or trading purposes.

Property, Plant and Equipment, Net

Property, plant and equipment is recorded at cost. Depreciation of property, plant and equipment is recorded principally on the straight line method over the estimated useful lives of the assets, which range as follows: machinery & equipment 3 to 15 years and buildings & improvements 10 to 30 years. Leasehold improvements are amortized over the shorter of the terms of the related leases or the estimated useful lives of the improvements. Interest cost is capitalized for qualifying assets during the assets' acquisition period. Maintenance and repairs are charged to expense, and renewals and betterments are capitalized. Gain or loss on dispositions is recorded in Other (income) expense, net.

Long-Lived Asset Testing

The Company estimates the depreciable lives of property, plant and equipment, and reviews long-lived assets for impairment whenever events, or changes in circumstances, indicate the carrying amount of such assets may not be recoverable. If the carrying values of the long-lived assets exceed the sum of the undiscounted cash flows, an impairment charge is recognized in the amount by which the carrying values exceeds their fair values. The Company performs such assessments at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities, which is generally at the plant level, operating company level or the reporting unit level, dependent on the level of interdependencies in the Company's operations.

The Company considers various factors in determining whether an impairment test is necessary, including among other things: a significant or prolonged deterioration in operating results and projected cash flows; significant changes in the extent or manner in which assets are used; technological advances with respect to assets which would potentially render them obsolete; the Company's strategy and capital planning; and the economic climate in the markets it serves. When estimating future cash flows and if necessary, fair value, the Company makes judgments as to the expected utilization of assets and estimated future cash flows related to those assets. The Company considers historical and anticipated future results, general economic and market conditions, the impact of planned business and operational strategies and other information available at the time the estimates are made. The Company believes these estimates are reasonable; however, changes in circumstances or conditions could have a significant impact on its estimates, which might result in material impairment charges in the future.

Business Combinations

When the Company acquires a business, it allocates the purchase price to the assets acquired, liabilities assumed and any noncontrolling interests based on their fair values at the acquisition date. Significant judgment may be used to determine these fair values including the use of appraisals, discounted cash flow models, market value for similar purchases or other methods applicable to the circumstances. The assumptions and judgments made by the Company when recording business combinations will have an impact on reported results of operations in the future.

Revenue Recognition

Diversified Industrial and Energy Segments

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and has since issued amendments thereto (collectively referred to herein as "ASC 606"). In January 1, 2018, we adopted ASC 606 using the modified retrospective method applied to those contracts which were not completed as of the adoption date. Results for reporting periods beginning after December 31, 2017 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for those periods. Our revenue recognition accounting policies applied prior to adoption of ASC 606 are outlined in the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2017. The disclosures included herein reflect our accounting policies under ASC 606.

Diversified Industrial revenues related to product sales are recognized when control of the promised goods is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods. This condition is usually met at a point-in-time when the product has been shipped to the customer, or in certain circumstances when the product has been delivered to the customer, depending on the terms of the contract. However, revenues for certain custom manufactured goods are recognized over time as the customer order is fulfilled (for example, contracts for sale of custom manufactured goods that do not have an alternative use and for which the Company has an enforceable right to payment). Certain customers may receive sales incentives, such as right of return, rebates, volume discounts and early payment discounts, which are accounted for as variable consideration. The Company estimates these amounts based on the expected incentive amount to be provided to customers and reduces revenues. Revenue is reported net of any sales or usage-based tax collected. Cash received from customers prior to shipment of goods, or otherwise not yet earned, is recorded as deferred revenue. Service revenues are generated primarily by the Energy segment's energy and sports businesses and by the repair and maintenance work performed on equipment used at mass merchants, supermarkets and restaurants in the Diversified Industrial segment. Service revenues are primarily recognized in the amount to which the entity has a right to invoice. The Company records all shipping and handling fees billed to customers as revenue. If revenue is recognized for the related good before the shipping and handling activities occur, the related costs of those shipping and handling activities are accrued.

The Company has also entered into rebate agreements with certain customers. These programs are typically structured to incentivize the customers to increase their annual purchases from the Company. The rebates are usually calculated as a percentage of the purchase amount, and such percentages may increase as the customer's level of purchases rise. Rebates are recorded as a reduction of net sales in the Company's consolidated statements of operations. As of December 31, 2018 and 2017, accrued rebates payable totaled $12,345 and $8,300, respectively, and are included in Accrued liabilities on the Company's consolidated balance sheets.

Financial Services Segment

WebBank generates revenue through a combination of interest income and non-interest income. Interest income is derived from interest and fees earned on loans and investments. Interest income is accrued on the unpaid principal balance, including amortization of premiums and accretion of discounts. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield over the estimated life of the loan. Non-interest income is primarily derived from premiums on the sale of loans, loan servicing fees, origination fees earned on loans and fee income on contractual lending arrangements.

Concentration of Revenue

No single customer accounted for 5% or more of the Company's consolidated revenues in 2018 or 2017. In 2018 and 2017, the 10 largest customers accounted for approximately 19% and 18%, respectively, of the Company's consolidated revenues.

Fair Value Measurements

The Company measures certain assets and liabilities at fair value (see Note 18 - "Fair Value Measurements"). Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair values of assets and liabilities are determined based on a three-level measurement input hierarchy. Level 1 inputs are quoted prices in active markets for identical assets or liabilities as of the measurement date. Level 2 inputs are other than quoted market prices that are observable, either directly or indirectly, for an asset or liability. Level 2 inputs can include quoted prices in active markets for similar assets or liabilities, quoted prices in a market that is not active for identical assets or liabilities, or other inputs that can be corroborated by observable market data. Level 3 inputs are unobservable for the asset or liability when there is little, if any, market activity for the asset or liability. Level 3 inputs are based on the best information available, and may include data developed by the Company.

Equity-Based Compensation

The Company accounts for restricted stock units granted to employees and non-employee directors as compensation expense, which is recognized in exchange for the services received. The compensation expense is based on the fair value of the equity instruments on the grant-date and is recognized as an expense over the service period of the recipients.

Income Taxes

SPLP and certain of its subsidiaries, as limited partnerships, are generally not responsible for federal and state income taxes, and their profits and losses are passed directly to their partners for inclusion in their respective income tax returns. SPLP's subsidiaries that are corporate entities are subject to federal and state income taxes and file corporate income tax returns.

SPLP's subsidiaries that are subject to income taxes use the liability method of accounting for such taxes. Under the liability method, deferred tax assets and deferred tax liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and deferred tax liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and deferred tax liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Such subsidiaries evaluate the recoverability of deferred tax assets and establish a valuation allowance when it is more likely than not that some portion of the deferred tax assets will not be realized.

When tax returns are filed, it is highly certain that most positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the Company's consolidated financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50% likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is provided for and reflected as a liability for unrecognized tax benefits on the Company's consolidated balance sheets, along with any associated interest and penalties that would be payable to the taxing authorities upon examination.

SPLP's policy is to record estimated interest and penalties related to the underpayment of income taxes as income tax expense in its consolidated statements of operations.

The Company does not release income tax effects from AOCI until the underlying asset or liability to which the income tax relates has been derecognized from the balance sheet or otherwise terminated.

Foreign Currency Translation

Assets and liabilities of SPLP's foreign subsidiaries are translated at current exchange rates and related revenues and expenses are translated at average rates of exchange in effect during the year. Resulting cumulative translation adjustments are recorded as a separate component of other comprehensive income or loss. Gains and losses arising from transactions denominated in a currency other than the functional currency of the reporting entity are included in earnings.

Legal Contingencies

The Company provides for legal contingencies when the liability is probable and the amount of the associated loss is reasonably estimable. The Company regularly monitors the progress of legal contingencies and revises the amounts recorded in the period in which a change in estimate occurs.

Environmental Liabilities

The Company accrues for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study.

Such accruals are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

New or Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASC 606 relating to revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services, and the guidance defines a five-step process to achieve this core principle. ASC 606 also requires additional disclosure about the nature, amount, timing and uncertainty of revenues and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The Company adopted ASC 606 as of January 1, 2018 using the modified retrospective transition method. For additional information, see Note 3 - "Revenues."

In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10), which eliminates the requirement to classify equity securities with readily determinable market values as either available-for-sale or trading securities, and requires that equity investments, other than those accounted for under the traditional equity method of accounting, be measured at their fair value with changes in fair value recognized in net income or loss. In the past, changes in fair value were reported in the Company's consolidated statement of comprehensive (loss) income and in AOCI. Equity investments that do not have readily determinable market values may be measured at cost under ASU 2016-01, subject to an assessment for impairment. We adopted ASU 2016-01 effective January 1, 2018. Upon adoption, we recorded a cumulative effect reclassification adjustment from AOCI to Partners' capital of $91,078, which represented the accumulated net unrealized gain on equity securities that was held in AOCI as of December 31, 2017. See also Note 15 - "Capital and Accumulated Other Comprehensive Loss." Furthermore, to have a comparable presentation in our prior-period financial statements after adoption of ASU 2016-01 in 2018, we reclassified realized gains of $790 for the year ended December 31, 2017 from Other (income) expense, net to Realized and unrealized losses (gains) on securities, net in both the consolidated statement of operations and consolidated statement of cash flows for 2017.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is effective for public companies for annual reporting periods beginning after December 15, 2018, including interim periods within those fiscal years. The new standard establishes a right-of-use ("ROU") model that requires a lessee to record a ROU asset and a lease liability, measured on a discounted basis, on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which clarified various aspects of the guidance under ASU 2016-02. Originally, entities were required to adopt ASU 2016-02 using a modified retrospective approach, which required prior periods to be presented under this new standard with certain practical expedients available. However, in July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which now allows entities the option of recognizing the cumulative effect of applying the new standard as an adjustment to the opening balance of retained earnings in the year of adoption (January 1, 2019) while continuing to present all prior periods under previous lease accounting guidance. ASU 2016-02 and its various amendments and clarifications are collectively referred to herein as "ASC 842."

The Company will adopt ASC 842 in the first quarter of 2019 using the alternative modified transition method. Under this method, the cumulative-effect adjustment to the opening balance of retained earnings is recognized on the date of adoption with prior periods not restated. The Company will also elect to use the package of practical expedients permitted under the transition guidance, such as, carryforward of our historical lease classification, no reassessment on whether an expired or existing contract contains an embedded lease, no reassessment of initial direct costs for any leases that exist prior to adoption of the new standard and to consolidate lease and non-lease components. We are also electing to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term.

The Company has completed its implementation plan for the new lease standard, which includes an information system, and business process and control changes, to accumulate the appropriate data in order to calculate and record the recognition of ROU assets, lease liabilities and the related expense recognition. We estimate that based on our portfolio of leases as of December 31, 2018, approximately $51,000 of ROU lease assets and $53,000 of lease liabilities will be recognized on our consolidated balance sheet upon adoption, primarily relating to building rentals.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new standard changes the impairment model for most financial assets that are measured at amortized cost and certain other instruments, including trade receivables, from an incurred loss model to an expected loss model and adds certain new required disclosures. Under the expected loss model, entities will recognize estimated credit losses to be incurred over the entire contractual term of the instrument rather than delaying recognition of credit losses until it is probable the loss has been incurred. The new standard is effective for the Company's 2020 fiscal year with early adoption permitted for all entities in fiscal years beginning after December 15, 2018. The Company is currently evaluating the potential impact of this new guidance; however, it expects that it could have a significant impact on the Company's ALLL.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This new standard provides guidance to help decrease diversity in practice in how certain cash receipts and cash payments are classified in the statement of cash flows. The amendments in ASU 2016-15 provide guidance on eight specific cash flow issues. We adopted ASU 2016-15 effective January 1, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This new standard provides guidance on the classification of restricted cash in the statement of cash flows. We adopted ASU 2016-18 effective January 1, 2018. As a result of the adoption of ASU 2016-18, in the consolidated statement of cash flows for the year ended December 31, 2017, we reclassified $15,629 of restricted cash.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This new standard provides guidance to help determine more clearly what is a business acquisition, as opposed to an asset acquisition.The amendments provide a screen to help determine when a set of components is a business by reducing the number of transactions in an acquisition that need to be evaluated. The new standard states that to classify the acquisition of assets as a business, there must be an input and a substantive process that jointly contribute to the ability to create outputs, with outputs being defined as the key elements of the business. If all of the fair value of the assets acquired are concentrated in a single asset group, this would not qualify as a business. The Company adopted ASU 2017-01 effective January 1, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This new standard simplifies subsequent measurements of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, entities will perform their interim or annual goodwill impairment testing by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge based on the amount that the carrying amount exceeds the reporting unit's fair value. The loss recognized should not exceed the total goodwill allocated to the reporting unit. The amendments in ASU 2017-04 are effective for the Company's 2020 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This new standard requires the components of net benefit cost to be disaggregated within the statement of operations, with service cost being included in the same line item as other compensation costs, and any other components being presented outside of operating income. The Company adopted ASU 2017-07 effective January 1, 2018. Since the Company's significant pension plans have been frozen, there is no substantial service cost associated with such plans and therefore, the adoption of ASU 2017-07 did not have a material impact on the Company's consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. This new standard provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The standard states that entities should account for the effects of a modification unless the fair value of the modified award is the same as the fair value of the original award, the vesting conditions do not change, and the classification as an equity instrument or a liability instrument is the same. We adopted ASU 2017-09 effective January 1, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This new standard was created to refine and expand hedge accounting for both financial and commodity risk in order to simplify the current application of hedge accounting guidance in current U.S. GAAP. This new standard creates more transparency around how hedging results are presented, both in the notes and on the face of the financial statements. The amendments in ASU 2017-12 are effective for the Company's 2019 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The new standard provides financial statement preparers with an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the federal Tax Cuts and Jobs Act ("Act") is recorded. The amendments in ASU 2018-02 are effective for the Company's 2019 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In March 2018, the FASB issued ASU 2018-05, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. ASU 2018-05 applies to income tax effects from the enactment of the Act in December 2017. ASU 2018-05 allows a Company to report as provisional those amounts where the Company does not have the necessary information available, prepared or analyzed in reasonable detail to complete the accounting under Accounting Standards Codification Topic 740. ASU 2018-05 further allows a measurement period, not to exceed one year from the enactment date of Act, during which an entity may need to reflect adjustments to its provisional amounts. ASU 2018-05 requires that any adjustments to provisional amounts during the measurement period be included in income from continuing operations as an adjustment to tax expense or benefit, and also requires certain disclosures. The provisions of ASU 2018-05 were effective as of the enactment date of the Act, December 22, 2017.

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This new standard was created to simplify the accounting for share-based payments to nonemployees. This standard provides guidance on how to account for share-based payment transactions with nonemployees in which a grantor acquires goods or services to be used or consumed in the grantor's own operations by issuing share-based payment awards. The amendments in ASU 2018-07 are effective for the Company's 2019 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on fair value measurements. The amendments in ASU 2018-13 are effective for the Company's 2020 fiscal year, except that the standard permits an entity to early adopt any removed or modified disclosures upon issuance of ASU No. 2018-13 and delay adoption of the additional disclosures until the effective date. Because ASU 2018-13 affects disclosure only, management does not expect that the full adoption of this standard will have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 modifies the disclosure requirements for employers that sponsor defined benefit pension and other post-retirement plans. The amendments in ASU 2018-14 are effective for the Company's 2021 fiscal year. Because ASU 2018-14 affects disclosure only, management does not expect that the adoption of this standard will have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments in ASU 2018-15 are effective for the Company's 2020 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

Revenue from Contract with Customer [Abstract]

Revenues

REVENUES

Adoption of ASC 606, "Revenue from Contracts with Customers"

On January 1, 2018, the Company adopted ASC 606 for all contracts with customers using the modified retrospective transition method. The Company recognized a net increase of $1,034 to Partners' capital due to the cumulative impact of adopting ASC 606. The impact to Partners' capital was primarily related to the timing of when revenue is recognized. While revenue from most contracts will continue to be recognized at a point-in-time, revenue from other contracts (for example, contracts for sale of custom manufactured goods that do not have an alternative use and for which the Company has an enforceable right to payment) will be recognized over time. The comparative information has not been restated and continues to be reported under the accounting standards in effect for those periods. For the year ended December 31, 2018, ASC 606 did not have a material impact on the Company's consolidated financial statements, including total revenue.

Revenue Recognition Accounting Policies

Revenues are recognized when control of the promised goods or services are transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services.

The Company records all shipping and handling fees billed to customers as revenue. The Company has elected to account for shipping and handling activities that are performed after the customer obtains control of a good as activities to fulfill the promise to transfer the good. If revenue is recognized for the related good before the shipping and handling activities occur, the related costs of those shipping and handling activities are accrued.

Sales and usage-based taxes are excluded from revenues. The Company does not have any material service-type warranty arrangements. The expected costs associated with the Company's assurance warranties continue to be recognized as expense when the products are sold. The Company does not have any material significant financing arrangements as payment is received shortly after the goods are sold or services are performed.

Standalone Selling Price

Generally, the Company's sales contracts with customers contain only one performance obligation. In certain circumstances, contracts with customers may include multiple performance obligations. For such arrangements, the Company allocates revenue to each performance obligation based on its relative standalone selling price. The Company generally determines the standalone selling price based on the prices charged to similar customers or by using the expected cost plus margin approach. The Company's performance obligations are generally part of contracts with customers that have a duration of less than one year, and therefore, the Company has not provided disclosures with respect to remaining performance obligations.

Practical Expedients and Exemptions

Given the typical duration of the Company's contracts with customers, as noted directly above, is less than one year, in accordance with the standard, the Company generally expenses sales commissions when incurred because the amortization period would have been one year or less. These costs are recorded within Selling, general and administrative expenses.

For certain of the services that the Company's Diversified Industrial and Energy segments provide, the Company has determined that it has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of the Company's performance completed to date, and therefore, the Company recognizes revenue in the amount to which the entity has a right to invoice.

Disaggregation of Revenues

Revenues are disaggregated at the Company's segment level since the segment categories depict how the nature, amount, timing and uncertainty of revenues and cash flows are affected by economic factors. For additional details related to the Company's reportable segments see Note 21 - "Segment Information."

The following table presents the Company's revenues disaggregated by geography for the year ended December 31, 2018. The Company's revenues are primarily derived domestically. Foreign revenues are based on the country in which the legal subsidiary generating the revenue is domiciled. Revenue from any single foreign country was not material to the Company's consolidated financial statements.

	Year Ended December 31, 2018
United States	$	1,368,778
Foreign (a)	215,836
Total revenue	$	1,584,614

(a) Foreign revenues are primarily related to the Company's API Group plc ("API") business, which is domiciled in the United Kingdom.

Diversified Industrial Revenues

The Diversified Industrial segment is comprised of manufacturers of engineered niche industrial products. The majority of revenues recognized are for the sale of manufactured goods in the United States. Other revenue recognized is for repair and maintenance services. Customer contracts are generally short-term in nature and are based on individual customer purchase orders. The terms and conditions of the customer purchase orders are dictated by either the Company's standard terms and conditions or by a master service agreement.

Diversified Industrial revenues related to product sales are recognized when control of the promised goods is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods. This condition is usually met at a point-in-time when the product has been shipped to the customer, or in certain circumstances when the product has been delivered to the customer, depending on the terms of the contract. However, revenues for certain custom manufactured goods are recognized over time as the customer order is fulfilled (for example, contracts for sale of custom manufactured goods that do not have an alternative use and for which the Company has an enforceable right to payment). Generally, a cost incurred input method is used to determine the timing of revenue recognition for over time arrangements. Service revenues are primarily recognized in the amount to which the entity has a right to invoice.

Certain customers may receive sales incentives, such as right of return, rebates, volume discounts and early payment discounts, which are accounted for as variable consideration. The Company estimates these amounts based on the expected incentive amount to be provided to customers and reduces revenues, and these estimates are typically constrained. The Company adjusts its estimate of revenue at the earlier of when the expected value or most likely amount of consideration we expect to receive changes or when the consideration becomes fixed.

Energy Revenues

The Energy segment provides drilling and production services to the oil & gas industry in the United States. The services provided include well completion and recompletion, well maintenance and workover, snubbing, flow testing, down hole pumping, plug and abatement, well logging and perforating wireline services. Service revenues are recognized in the amount to which the entity has a right to invoice. Consideration for Energy contracts is generally fixed.

A portion of Energy revenues are service revenues related to Energy's youth sports business. These service revenues are recognized when services are provided to the customer, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those services. Consideration for the Energy's sports business contracts is generally fixed.

Financial Services Revenues

WebBank generates revenues through a combination of interest income and non-interest income. Interest income is derived from interest and fees earned on loans and investments. Interest income is accrued on the unpaid principal balance, including amortization of premiums and accretion of discounts. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield over the estimated life of the loan. Non-interest income is primarily derived from premiums on the sale of loans, loan servicing fees, origination fees earned on loans and fee income on contractual lending arrangements. WebBank's revenue streams are primarily accounted for outside of the scope of ASC 606.

Contract Balances

The timing of revenue recognition, billings and cash collections results in billed trade receivables, unbilled receivables (contract assets), return assets and deferred revenue (contract liabilities) on the consolidated balance sheet.

Contract Assets

Unbilled receivables arise when the timing of billings to customers differs from the timing of revenue recognition, such as when the Company recognizes revenue over time before a customer can be billed. Contract assets are classified as Prepaid expenses and other current assets on the consolidated balance sheet. The balances of contract assets as of December 31, 2018 and January 1, 2018 were $8,969 and $3,480, respectively. As of December 31, 2018, and January 1, 2018, the Company's return assets account was not material.

Contract Liabilities

The Company records deferred revenues when cash payments are received or due in advance of the Company's performance, including amounts which are refundable, which are recorded as contract liabilities. Contract liabilities are classified as Other current liabilities on the consolidated balance sheet based on the timing of when the Company expects to recognize revenue. The balances of contract liabilities as of December 31, 2018 and January 1, 2018 were $5,900 and $3,920, respectively. For the year ended December 31, 2018, the Company recognized revenue of $3,865 that was included in the contract liability balance at the date of adoption.

2018 Acquisitions

On June 1, 2018, the Company completed the acquisition of PST Group, Inc. ("PST") located in Muskego, Wisconsin for approximately $4,620. PST manufactures precision-engineered threaded components and custom ball screw assemblies, providing linear motion and power transmission solutions across a range of industries. PST is included in the Company's Diversified Industrial segment.

On February 16, 2018, the Company completed the acquisition of certain assets and liabilities of Dunmore Corporation in the U.S. and the share purchase of Dunmore Europe GmbH in Germany (collectively, "Dunmore") for a purchase price of $69,604, which includes assumed debt and is subject to an earn-out based on future earnings during the period from January 1, 2018 through December 31, 2019, as provided in the purchase agreement. In no case will the purchase price, including the potential earn-out, exceed $80,000. Dunmore manufactures and distributes coated, laminated and metallized films for engineered applications in the imaging, aerospace, insulation and solar photo-voltaic markets and also provides products for custom and special applications. Dunmore reports into the Company's Packaging business in its Diversified Industrial segment. In connection with the Dunmore acquisition, the Company recorded inventories, property, plant and equipment, other intangible assets and goodwill on a preliminary basis, totaling approximately $7,700, $30,600, $19,900 and $13,006, respectively, as well as other assets and liabilities. Other intangible assets consist of customer relationships of $12,600, trade names of $3,300, developed technology of $3,300 and customer order backlog of $700. The expected useful lives are 15 years for customer relationships, indefinite for trade names and 10 years for developed technology. The customer order backlog was amortized based on the expected period over which the orders were fulfilled of four months. The goodwill from the Dunmore acquisition consists largely of the synergies expected from combining the operations of Dunmore and the Company's existing Packaging business. The goodwill assigned to Dunmore Corporation of $5,176 is expected to be deductible for income tax purposes, while the goodwill assigned to Dunmore Europe GmbH of $7,830 is not tax deductible. The preliminary purchase price allocation is subject to finalization of valuations of certain acquired assets and liabilities.

On December 31, 2018, the Company increased its ownership in a former equity investee, iGo, Inc. ("iGo") from 45.8% to 80.2%. For further discussion, see Note 15 - "Capital and Accumulated Other Comprehensive Loss."

2017 Acquisition

On May 19, 2017, the Company acquired an 80% interest in Basin Well Logging Wireline Services, Inc. ("Basin") located in Farmington, New Mexico for approximately $5,100. Basin provides wireline services to major oil & gas exploration and production companies in the U.S. and specializes in cased-hole wireline logging and perforating services for exploration and production companies with wells in New Mexico, Texas, Utah, Arizona and Colorado. In connection with the Basin acquisition, which was not material to SPLP's operations, goodwill totaling approximately $2,353 was recorded.

(a) The carrying value is considered to be representative of fair value because the rates of interest are not significantly different from market interest rates for instruments with similar maturities. The fair value of loans receivable, including loans held for sale, was $510,543 and $270,068 at December 31, 2018 and 2017, respectively.

Loans with a carrying value of approximately $56,851 and $57,436 were pledged as collateral for potential borrowings at December 31, 2018 and 2017, respectively. WebBank serviced $3,044 and $3,125 in loans for others at December 31, 2018 and 2017, respectively.

WebBank sold loans totaling $21,116,184 in 2018 and $16,471,432 in 2017 that were classified as loans held for sale. The sold loans were derecognized from the consolidated balance sheets. Loans classified as loans held for sale primarily consist of credit cards and other consumer and small business loans. The loans are mainly sold to WebBank's partners. Amounts added to loans held for sale during these same periods were $21,167,553 and $16,528,082, respectively.

Allowance for Loan Losses

The ALLL represents an estimate of probable and estimable losses inherent in the loan portfolio as of the balance sheet date. Losses are charged to the ALLL when incurred. Generally, commercial loans are charged off or charged down at the point at which they are determined to be uncollectible in whole or in part. Consumer term loans are charged off at 120 days past due and open-end consumer and small and medium business loans are charged off at 180 days past due unless the loan is well secured and in the process of collection. The amount of the ALLL is established by analyzing the portfolio at least quarterly and a provision for or reduction of loan losses is recorded so that the ALLL is at an appropriate level at the balance sheet date. The methodologies used to estimate the ALLL depend upon the impairment status and portfolio segment of the loan. Loan groupings are created for each loan class and are then graded against historical and industry loss rates.

After applying historic loss experience, the quantitatively derived level of ALLL is reviewed for each segment using qualitative criteria. Various risk factors are tracked that influence our judgment regarding the level of the ALLL across the portfolio segments. Primary qualitative factors that may be reflected in the quantitative models include:

• Asset quality trends

• Risk management and loan administration practices

• Portfolio management and controls

• Effect of changes in the nature and volume of the portfolio

• Changes in lending policies and underwriting policies

• Existence and effect of any portfolio concentrations

• National economic business conditions and other macroeconomic adjustments

• Regional and local economic and business conditions

• Data availability and applicability

• Industry monitoring

• Value of underlying collateral

Changes in these factors are reviewed to ensure that changes in the level of the ALLL are consistent with changes in these factors. The magnitude of the impact of each of these factors on the qualitative assessment of the ALLL changes from quarter to quarter according to the extent these factors are already reflected in historic loss rates and according to the extent these factors diverge from one another. Also considered is the uncertainty inherent in the estimation process when evaluating the ALLL. Changes in the ALLL are summarized as follows:

Credit Quality Indicators

In addition to the past due and nonaccrual criteria, loans are analyzed using a loan grading system. Generally, internal grades are assigned to loans based on the performance of the loans, financial/statistical models and loan officer judgment. For consumer loans and some commercial and industrial loans, the primary credit quality indicator is payment status. Reviews and grading of loans with unpaid principal balances of $100 or more is performed once per year. Grades follow definitions of Pass, Special Mention, Substandard and Doubtful, which are consistent with published definitions of regulatory risk classifications. The definitions of Pass, Special Mention, Substandard and Doubtful are summarized as follows:

• Pass: An asset in this category is a higher quality asset and does not fit any of the other categories described below. The likelihood of loss is considered remote.

• Special Mention: An asset in this category has a specific weakness or problem but does not currently present a significant risk of loss or default as to any material term of the loan or financing agreement.

• Substandard: An asset in this category has a developing or currently minor weakness or weaknesses that could result in loss or default if deficiencies are not corrected or adverse conditions arise.

• Doubtful: An asset in this category has an existing weakness or weaknesses that have developed into a serious risk of significant loss or default with regard to a material term of the financing agreement.

Outstanding loan balances (accruing and nonaccruing) categorized by these credit quality indicators are summarized as follows:

December 31, 2018	Non - Graded		Pass		Special Mention		Sub- standard		Doubtful		Total Loans
Commercial real estate loans	$	—	$	617	$	—	$	15	$	—	$	632

Impaired Loans

Loans are considered impaired when, based on current information and events, it is probable that WebBank will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments. When loans are impaired, an estimate of the amount of the balance that is impaired is made and a specific reserve is assigned to the loan based on the estimated present value of the loan's future cash flows discounted at the loan's effective interest rate, the observable market price of the loan or the fair value of the loan's underlying collateral less the cost to sell. When the impairment is based on the fair value of the loan's underlying collateral, the portion of the balance that is impaired is charged off, such that these loans do not have a specific reserve in the ALLL. Payments received on impaired loans that are accruing are recognized in interest income, according to the contractual loan agreement. WebBank recognized $122 and $4 on impaired loans for the years ended December 31, 2018 and 2017, respectively. Payments received on impaired loans that are on nonaccrual are not recognized in interest income, but are applied as a reduction to the principal outstanding. Payments are recognized when cash is received. Information on impaired loans is summarized as follows:

Short-Term Investments

Marketable Securities

The Company's short-term investments primarily consist of its marketable securities portfolio. The classification of marketable securities as a current asset is based on the intended holding period and realizability of the investments. The Company's portfolio of marketable securities at December 31, 2018 and 2017 was as follows:

	December 31, 2018											December 31, 2017
	Cost			Gross Unrealized Gains		Gross Unrealized Losses			Fair value			Cost			Gross Unrealized Gains		Gross Unrealized Losses			Fair value
Short-term deposits	$	21,064		$	—	$	—		$	21,064		$	35,834		$	—	$	—		$	35,834

Total marketable securities	25,597			—		(3,094		)	22,503			80,222			16,568		(2,643		)	94,147
Amounts classified as cash equivalents	(21,064		)	—		—			(21,064		)	(35,834		)	—		—			(35,834		)
Amounts classified as marketable securities	$	4,533		$	—	$	(3,094	)	$	1,439		$	44,388		$	16,568	$	(2,643	)	$	58,313

Proceeds from sales of marketable securities were approximately $47,200 and $16,596 in 2018 and 2017, respectively. The Company determines gains and losses from sales of marketable securities based on specific identification of the securities sold. Gross realized gains and losses from sales of marketable securities, which are reported as a component of Realized and unrealized losses (gains) on securities, net in the Company's consolidated statements of operations, were as follows:

	Year Ended December 31,
	2018			2017
Gross realized gains	$	16,499		$	637
Gross realized losses	(5,129		)	(545		)
Realized gains, net	$	11,370		$	92

Effective January 1, 2018 upon adoption of ASU 2016-01, unrealized gains or losses due to changes in fair value of securities are being accounted for as a component of Realized and unrealized losses (gains) on securities, net in the Company's consolidated statement of operations. Prior to January 1, 2018, changes in fair value were recognized in Partners' capital as other comprehensive income or loss, except for other-than-temporary impairments, which were reflected as a reduction of cost and charged to the consolidated statements of operations.

The fair value of marketable securities with unrealized losses at December 31, 2018 and 2017, and the duration of time that such losses had been unrealized, were as follows:

	Less than 12 Months					12 Months or Greater					Total
	Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses			Fair Value		Gross Unrealized Losses
December 31, 2018:
Corporate securities	$	396	$	(322	)	$	1,043	$	(2,772	)	$	1,439	$	(3,094	)
Total	$	396	$	(322	)	$	1,043	$	(2,772	)	$	1,439	$	(3,094	)

December 31, 2017:
Corporate securities	$	5,801	$	(2,558	)	$	398	$	(85	)	$	6,199	$	(2,643	)
Total	$	5,801	$	(2,558	)	$	398	$	(85	)	$	6,199	$	(2,643	)

The corporate securities with gross unrealized losses primarily consist of investments in equity securities of publicly traded entities. In 2017, the Company evaluated such securities to determine if certain unrealized losses represented other-than-temporary impairments. This determination was based on several factors, including adverse changes in the market conditions and economic environments in which the entities operate, as well as the length of time and extent to which fair value had been less than the cost basis, the financial condition and near-term prospects of the entities, and the intent and ability to hold the corporate securities for a period of time sufficient to allow for any anticipated recovery in market value. The Company recognized asset impairment charges of $2,028 for the year ended December 31, 2017.

(c) Represents investment in STCN preferred stock. On December 15, 2017, the Company entered into an agreement pursuant to which STCN issued Series C convertible voting preferred stock for an aggregate purchase consideration of $35,000. Each share of preferred stock can be converted into shares of STCN's common stock at an initial conversion price equal to $1.96 per share, subject to appropriate adjustments for any stock dividend, stock split, stock combination, reclassification or similar transaction, among other things. Changes in fair value are recorded in the Company's consolidated statements of operations as the Company elected the fair value option to account for this investment. The convertible preferred shares, if converted as of December 31, 2018, when combined with the common shares owned by the Company, would result in the Company having a direct interest of approximately 45.6% of STCN's outstanding shares.

(d) Balance included the Company's investment in iGo as of December 31, 2017. The Company's ownership of iGo increased to 80.2% on December 31, 2018, as discussed in Note 15 - "Capital and Accumulated Other Comprehensive Loss," and iGo is now a consolidated subsidiary.

(e) Loss (income) from these investments is included in Realized and unrealized losses (gains) on securities, net in the consolidated statements of operations.

(f) Loss (income) from these investments is included in Loss (income) of associated companies, net of taxes in the consolidated statements of operations.

The Company's long-term investments (corporate securities) include common shares of Babcock & Wilcox Enterprises, Inc. ("BW"). The Company made investments totaling $76,261 in BW shares during 2018, increasing its ownership in BW to approximately 17.8%.

The Company had no proceeds from sales of securities classified in long-term investments for the years ended December 31, 2018 and 2017.

Equity Method Investments

The Company's investments in associated companies are accounted for under the equity method of accounting, primarily using the fair value option. Associated companies are included in the Diversified Industrial, Energy, and Corporate and Other segments. Certain associated companies have a fiscal year end that differs from December 31. Additional information for SPLP's significant investments in associated companies is as follows:

On November 14, 2017, the Company entered into a credit agreement ("Credit Agreement") that consolidated a number of its existing credit facilities into one combined, revolving credit facility covering substantially all of the Company's subsidiaries, with the exception of WebBank. The Credit Agreement provided for a revolving credit facility in an aggregate principal amount not to exceed $600,000, including a $55,000 subfacility for swing line loans and a $50,000 subfacility for standby letters of credit. Borrowings under the Credit Agreement bear interest, at the borrower's option, at annual rates of either the Base Rate or the Euro-Rate, as defined, plus an applicable margin as set forth in the Credit Agreement (1.50% and 2.50%, respectively, for Base Rate and Euro-Rate borrowings at December 31, 2018), and the Credit Agreement provides for a commitment fee to be paid on unused borrowings. The weighted average interest rate on the Credit Agreement was 4.93% at December 31, 2018. At December 31, 2018, letters of credit totaling $11,153 had been issued under the Credit Agreement, including $3,709 of the letters of credit guaranteeing various insurance activities, and $7,444 for environmental and other matters. The Credit Agreement permits SPLP, the parent, to fund the dividends on its preferred units and its routine corporate expenses. The Company's total availability under the Credit Agreement, which is based upon earnings and certain covenants as described in the Credit Agreement, was approximately $42,900 as of December 31, 2018.

On April 27, 2018, the Company entered into a first amendment to the Credit Agreement to allow the Company to (i) exercise certain subscription rights in BW common shares, (ii) increase the maximum aggregate principal amount to $700,000, (iii) increase the defined leverage ratios under the Credit Agreement by 0.25 "turns" for the fiscal quarters ending June 30, 2018, September 30, 2018 and December 31, 2018 and (v) make certain administrative changes.

On December 31, 2018, the Company entered into a second amendment to the Credit Agreement to allow the Company to (i) enter into the iGo transaction discussed in Note 15 - "Capital and Accumulated Other Comprehensive Loss," (ii) join iGo to the Credit Agreement and grant the lenders a security interest in its assets, (iii) provide an $18,500 sublimit for iGo's and its subsidiaries' borrowings and (iv) make certain administrative changes.

On January 31, 2019, the Company entered into a third amendment to the Credit Agreement to allow the Company to (i) convert $200,000 of the revolving credit commitments into a term loan with quarterly amortization equating to 5.0% per annum, (ii) amend certain defined leverage ratios under the Credit Agreement, increasing allowable leverage by 0.25 "turns" on a permanent basis through the maturity of the Credit Agreement, (iii) eliminate certain previously allowed investments, which would have reduced collateral available to the Company's lenders and (iv) make certain administrative changes. Accordingly, this third amendment to the Credit Agreement will add the following required principal repayments to the above long-term debt maturity table: $7,500 in 2019 and $10,000 in each of 2020, 2021 and 2022.

The Credit Agreement will expire, with all amounts outstanding due and payable, onNovember 14, 2022. The Credit Agreement is guaranteed by substantially all existing and thereafter acquired assets of the borrowers and the guarantors, as defined in the agreement,and a pledge of all of the issued and outstanding shares of capital stock of each of the borrowers' and guarantors' subsidiaries, and is fully guaranteed by the guarantors. The Credit Agreement is subject to certain mandatory prepayment provisions and restrictive and financial covenants, which include a maximum ratio limit on Total Leverage and a minimum ratio limit on Interest Coverage, as defined. The Company was in compliance with all financial covenants atDecember 31, 2018.

FINANCIAL INSTRUMENTS

FINANCIAL INSTRUMENTS

At December 31, 2018 and 2017, financial instrument liabilities and related restricted cash consisted of $12,434 and $15,629, respectively, related to short sales of corporate securities. Full year activity is summarized below for financial instrument liabilities and related restricted cash:

	Year Ended December 31,
	2018			2017
Balance, beginning of period	$	15,629		$	12,640
Settlement of short sales of corporate securities	(3,100		)	(94		)
Short sales of corporate securities	26			165
Net investment (gains) losses	(121		)	2,918
Balance, end of period	$	12,434		$	15,629

Short Sales of Corporate Securities

From time to time, the Company enters into short sale transactions on certain corporate securities in which it receives proceeds from the sale of such securities and incurs obligations to deliver such securities at a later date. Upon initially entering into such short sale transactions, the Company recognizes a liability equal to the fair value of the obligation, with a comparable amount of cash and cash equivalents reclassified as restricted cash. Subsequent changes in the fair value of such obligations, determined based on the closing market price of the securities, are recognized currently as gains or losses in the consolidated statements of operations, with a comparable adjustment made between unrestricted and restricted cash.

Foreign Currency Forward Contracts

The Company enters into foreign currency forward contracts to hedge certain of its receivables and payables denominated in other currencies. In addition, the Company enters into foreign currency forward contracts to hedge the value of certain of its future sales denominated in Euros and the value of certain of its future purchases denominated in USD. These hedges are associated with certain of the Company's operations located in the United Kingdom and have settlement dates ranging through December 2019. The forward contracts that are used to hedge the risk of foreign exchange movement on its receivables and payables are accounted for as fair value hedges. At December 31, 2018, there were contracts in place to buy Sterling and sell Euros in the amount of €9,800. The fair values of these derivatives are recognized as derivative assets and liabilities on the Company's consolidated balance sheets. The net change in fair value of the derivative assets and liabilities are recognized in the Company's consolidated statements of operations. The forward contracts that are used to hedge the value of the Company's future sales and purchases are accounted for as cash flow hedges. At December 31, 2018, there were contracts in place to hedge the value of future sales denominated in Euros in the amount of €10,300 and the value of future purchases denominated in USD in the amount of $450. These hedges are fully effective, and, accordingly, the changes in fair value are recorded in AOCI and, at maturity, any gain or loss on the forward contract is reclassified from AOCI into the Company's consolidated statements of operations.

WebBank - Economic Interests in Loans

WebBank's derivative financial instruments represent on-going economic interests in loans made after they are sold. These derivatives are carried at fair value on a gross basis in Other non-current assets on the Company's consolidated balance sheets and are classified within Level 3 in the fair value hierarchy (see Note 18 - "Fair Value Measurements"). At December 31, 2018, outstanding derivatives mature within 5 years. Gains and losses resulting from changes in the fair value of derivative instruments are accounted for in the Company's consolidated statements of operations in Financial services revenue. Fair value represents the estimated amounts that WebBank would receive or pay to terminate the contracts at the reporting date based on a discounted cash flow model for the same or similar instruments. WebBank does not enter into derivative contracts for speculative or trading purposes.

Precious Metal and Commodity Inventories

As of December 31, 2018, the Company had the following outstanding forward contracts with settlement dates through January 2019. There were no futures contracts outstanding at December 31, 2018.

Commodity	Amount	Notional Value
Silver	264,822 ounces	$	3,993
Gold	2,733 ounces	$	3,467
Palladium	775 ounces	$	951
Copper	150,000 pounds	$	388
Tin	20 metric tons	$	392

Of the total forward contracts outstanding, 18,895 ounces of silver and substantially all the copper contracts are designated and accounted for as fair value hedges and are associated primarily with the Company's precious metal inventory carried at fair value. The remaining outstanding forward contracts for silver, and all the contracts for gold, palladium and tin, are accounted for as economic hedges.

The forward contracts were made with a counterparty rated Aa2 by Moody's. Accordingly, the Company has determined that there is minimal credit risk of default. The Company estimates the fair value of its derivative contracts through the use of market quotes or with the assistance of brokers when market information is not available. The Company maintains collateral on account with the third-party broker, which varies in amount depending on the value of open contracts.

The fair value and carrying amount of derivative instruments on the Company's consolidated balance sheets and the effect of derivative instruments in the Company's consolidated statements of operations are shown in the following tables:

Financial Instruments with Off-Balance Sheet Risk

WebBank is a party to financial instruments with off-balance sheet risk. In the normal course of business, these financial instruments include commitments to extend credit in the form of loans as part of WebBank's lending arrangements. Those instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the consolidated balance sheets. The contractual amounts of those instruments reflect the extent of involvement WebBank has in particular classes of financial instruments.

At December 31, 2018 and 2017, WebBank's undisbursed loan commitments totaled $130,697 and $148,529, respectively. Commitments to extend credit are agreements to lend to a borrower who meets the lending criteria through one of WebBank's lending agreements, provided there is no violation of any condition established in the contract with the counterparty to the lending arrangement.

Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since certain of the commitments are expected to expire without the credit being extended, the total commitment amounts do not necessarily represent future cash requirements. WebBank evaluates each prospective borrower's credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by WebBank upon extension of credit, is based on management's credit evaluation of the borrower and WebBank's counterparty.

WebBank's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit is represented by the contractual amount of those instruments. WebBank uses the same credit policy in making commitments and conditional obligations as it does for on-balance sheet instruments.

PENSION AND OTHER POST-RETIREMENT BENEFITS

Defined Benefit Plan [Abstract]

PENSION AND OTHER POST-RETIREMENT BENEFITS

PENSION AND OTHER POST-RETIREMENT BENEFITS

The Company maintains several qualified and non-qualified pension plans and other post-retirement benefit plans. The Company's significant pension plans are discussed below. The Company's other pension and post-retirement benefit plans are not significant individually or in the aggregate.

Qualified Pension Plans - HNH

The Company's subsidiary, Handy & Harman Ltd. ("HNH") and its subsidiary, Handy & Harman ("H&H"), sponsor a defined benefit pension plan, the WHX Pension Plan, covering many of H&H's employees and certain employees of H&H's former subsidiary, Wheeling-Pittsburgh Corporation ("WPC"). The WHX Pension Plan was established in May 1998 as a result of the merger of the former H&H plans, which covered substantially all H&H employees, and the WPC plan. The WPC plan, covering most United Steel Workers of America-represented employees of WPC, was created pursuant to a collective bargaining agreement ratified on August 12, 1997. Prior to that date, benefits were provided through a defined contribution plan, the Wheeling-Pittsburgh Steel Corporation Retirement Security Plan ("RSP Plan"). The assets of the RSP Plan were merged into the WPC plan as of December 1, 1997. Under the terms of the WHX Pension Plan, the benefit formula and provisions for the WPC and H&H participants continued as they were designed under each of the respective plans prior to the merger.

The qualified pension benefits under the WHX Pension Plan were frozen as of December 31, 2005 and April 30, 2006 for hourly and salaried non-bargaining participants, respectively, with the exception of a single operating unit. In 2011, the benefits were frozen for the remainder of the participants. WPC employees ceased to be active participants in the WHX Pension Plan effective July 31, 2003, and as a result, such employees no longer accrue benefits under the WHX Pension Plan.

HNH's subsidiary, JPS Industries Holdings LLC ("JPS"), sponsors a defined benefit pension plan ("JPS Pension Plan"). Under the JPS Pension Plan, substantially all JPS employees who were employed prior to April 1, 2005 have benefits. The JPS Pension Plan was frozen effective December 31, 2005. Employees no longer earned additional benefits after that date. Benefits earned prior to December 31, 2005 will be paid out to eligible participants following retirement. The JPS Pension Plan was "unfrozen" for employees who were active employees on or after June 1, 2012. This new benefit, calculated based on years of service and a capped average salary, will be added to the amount of any pre-2005 benefit. The JPS Pension Plan was again frozen for all future accruals effective December 31, 2015, although unvested participants may still vest in accrued but unvested benefits.

Pension benefits under the WHX Pension Plan are based on years of service and the amount of compensation earned during the participants' employment. However, as noted above, the qualified pension benefits have been frozen for all participants.

Pension benefits for the WPC bargained participants include both defined benefit and defined contribution features, since the plan includes the account balances from the RSP Plan. The gross benefit, before offsets, is calculated based on years of service and the benefit multiplier under the plan. The net defined benefit pension plan benefit is the gross amount offset for the benefits payable from the RSP Plan and benefits payable by the Pension Benefit Guaranty Corporation from previously terminated plans. Individual employee accounts established under the RSP Plan are maintained until retirement. Upon retirement, participants who are eligible for the WHX Pension Plan and maintain RSP Plan account balances will normally receive benefits from the WHX Pension Plan. When these participants become eligible for benefits under the WHX Pension Plan, their vested balances in the RSP Plan become assets of the WHX Pension Plan. Although these RSP Plan assets cannot be used to fund any of the net benefit that is the basis for determining the defined benefit plan's net benefit obligation at the end of the year, the Company has included the amount of the RSP Plan accounts of $13,261 and $14,800 on a gross-basis as both assets and liabilities of the plan as of December 31, 2018 and 2017, respectively.

On December 30, 2016, the WHX Pension Plan was split into two plans by spinning off certain plan participants with smaller benefit obligations (which in the aggregate were equal to approximately 3.0% of the assets of the WHX Pension Plan), and assets equal thereto, to a new separate plan, the WHX Pension Plan II. The benefits of participants under the WHX Pension Plan II are equal to their accrued benefits under the benefit formula that was applicable to each participant under the WHX Pension Plan at the time of the plan spin-off. The total benefit liabilities of the two plans after the spin-off were equal to the benefit liabilities of the WHX Pension Plan immediately before the spin-off, and under the applicable spin-off rules, the WHX Pension Plan II was considered fully funded as of the date of the spin-off.

Net actuarial losses for the WHX Pension Plan are being amortized over the average future lifetime of the participants, which is expected to be approximately 17 years, and for the JPS Plan, 15 years. The Company believes that use of the future lifetime of the participants is appropriate because the plans are inactive.

API Plan

The Company's subsidiary, API, maintains a pension plan in the United Kingdom ("API Plan"). The API Plan is a defined benefit pension plan providing benefits based on final pensionable earnings, as defined in the API Plan, funded by the payment of contributions to a separately administered trust fund. Benefits under the API Plan were frozen, and the plan was closed to new participants in December 2008.

Certain employees of API's former Rahway, New Jersey plant participated in a multiemployer pension plan. For the year ended December 31, 2017, API recorded a one-time charge of $4,300 related to pension obligations associated with the closure of the Rahway, New Jersey plant, which charge is not included in the table below.

The following table presents the components of pension expense for the HNH and API pension plans:

	Year Ended December 31,
	2018			2017
Interest cost	$	20,999		$	21,910
Expected return on plan assets	(27,703		)	(25,969		)
Amortization of actuarial loss	9,888			9,228
Total	$	3,184		$	5,169

Actuarial assumptions used to develop the components of pension expense were as follows:

	2018		2017
Discount rates:
WHX Pension Plan	3.45	%	3.84	%
WHX Pension Plan II	3.33	%	3.64	%
JPS Pension Plan	3.40	%	3.81	%
API Pension Plan	2.50	%	2.65	%
HNH expected return on assets	6.50	%	6.50	%
API expected return on assets	3.80	%	3.87	%

The measurement date for plan obligations is December 31. The discount rate is the rate at which the plans' obligations could be effectively settled and is based on high quality bond yields as of the measurement date.

Summarized below is a reconciliation of the funded status for HNH's and API's qualified defined benefit pension plans:

The weighted average assumptions used in the valuations at December 31 were as follows:

	2018		2017
Discount rates:
WHX Pension Plan	4.10	%	3.45	%
WHX Pension Plan II	4.00	%	3.33	%
JPS Pension Plan	4.09	%	3.40	%
API Pension Plan	2.90	%	2.50	%

Pretax amounts included in Accumulated other comprehensive loss at December 31, 2018 and 2017 were as follows:

	HNH Plans				API Plan
	2018		2017		2018		2017
Prior service cost	$	—	$	—	$	2,475	$	—
Net actuarial loss	220,778		254,599		5,551		7,083
Accumulated other comprehensive loss	$	220,778	$	254,599	$	8,026	$	7,083

The pretax amount of actuarial losses included in Accumulated other comprehensive loss at December 31, 2018 that is expected to be recognized in net periodic benefit cost in 2019 is $10,075.

Other pretax changes in plan assets and benefit obligations recognized in comprehensive income (loss) are as follows:

	HNH Plans					API Plan
	Pension Benefits					Pension Benefits
	2018		2017			2018			2017
Current year actuarial gain (loss)	$	23,933	$	(24,333	)	$	1,300		$	6,339
Amortization of actuarial loss	9,888		9,228			—			—
Current year prior service cost	—		—			(2,634		)	—
Amortization of prior service credit	—		—			24			—
Impact of foreign exchange rate	—		—			367			—
Total recognized in comprehensive income (loss)	$	33,821	$	(15,105	)	$	(943	)	$	6,339

The actuarial gain in 2018 occurred principally because the discount rates used to measure benefit obligations for the HNH plans at the end of the fiscal year increased from the prior fiscal year end. In addition, the mortality assumptions were updated to reflect the results of a mortality study conducted in 2018, which also created an actuarial gain. Conversely, the actuarial loss in 2017 occurred principally because the discount rates used to measure benefit obligation for the HNH plans decreased in that year.

Benefit obligations were in excess of plan assets for each of the pension plans at both December 31, 2018 and 2017. Additional information for the plans with accumulated benefit obligations in excess of plan assets follows:

	HNH Plans				API Plan
	2018		2017		2018		2017
Projected benefit obligation	$	498,812	$	601,194	$	135,612	$	152,006
Accumulated benefit obligation	$	498,812	$	601,194	$	135,612	$	152,006
Fair value of plan assets	$	308,489	$	349,819	$	125,833	$	140,634

In determining the expected long-term rate of return on plan assets, the Company evaluated input from various investment professionals. In addition, the Company considered its historical compound returns, as well as the Company's forward-looking expectations. The Company determines its actuarial assumptions for its pension plans each year to calculate liability information as of December 31, and pension expense or income for the following year. The discount rate assumption is derived from the rate of return on high-quality bonds as of December 31 of each year.

The Company's investment policy is to maximize the total rate of return with a view to long-term funding objectives of the pension plans to ensure that funds are available to meet benefit obligations when due. Pension plan assets are diversified to the extent necessary to minimize risk and to achieve an optimal balance between risk and return. There are no target allocations. The HNH plans' assets are diversified as to type of assets, investment strategies employed and number of investment managers used. Investments may include equities, fixed income, cash equivalents, convertible securities and private investment funds. Derivatives may be used as part of the investment strategy. The Company may direct the transfer of assets between investment managers in order to rebalance the portfolio in accordance with asset allocation guidelines established by the Company.

The fair value of pension investments is defined by reference to one of three categories (Level 1, Level 2 or Level 3) based on the reliability of inputs, as such terms are defined in Note 2 - "Summary of Significant Accounting Policies." HNH's plans' assets at December 31, 2018 and 2017, by asset category, are as follows:

(1) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy.

(2) Hedge funds and common trust funds are comprised of shares or units in commingled funds that may not be publicly traded. The underlying assets in these funds are primarily publicly traded equity securities and fixed income securities.

(3) The limited partnership is a direct lending private debt fund, which serves as an alternative source of liquidity for the shipping industry.

(4) The limited partnership's strategy is to build a concentrated portfolio of 8-10 companies with $100 to $1,000 of equity allocated per investment. Investments will be control positions of minority stakes with significant protections and influence. The strategy will focus on the North American and Asian financial, industrial, energy, consumer and business service sectors.

(5) The limited partnership operates as a fund of funds. The underlying assets in this fund are generally expected to be illiquid. The limited partnership's investment strategy is to seek above-average rates of return and long-term capital growth by investing in a broad range of investments, including, but not limited to, global distressed corporate securities, activist equities, value equities, post-reorganizational equities, municipal bonds, high yield bonds, leveraged loans, unsecured debt, collateralized debt obligations, mortgage-backed securities, commercial mortgage-backed securities, direct lending and sovereign debt.

(6) The offshore feeder fund's Pan-Asia strategy employs a value-oriented and concentrated approach with a long-term horizon and seeks to build a portfolio of independent long and short positions with access to small/mid-cap opportunities.

(7) The JPS Pension Plan holds a deposit administration group annuity contract with an immediate participation guarantee from Transamerica Life Insurance Company ("TFLIC"). The TFLIC contract unconditionally guarantees benefits to certain salaried JPS Pension Plan participants earned through June 30, 1984 in the pension plan of a predecessor employer. The assets deposited under the contract are held in a separate custodial account ("TFLIC Assets"). If the TFLIC Assets decrease to the level of the trigger point (as defined in the contract), which represents the guaranteed benefit obligation representing the accumulated plan benefits as of June 30, 1984, TFLIC has the right to cause annuities to be purchased for the individuals covered by these contract agreements. No annuities have been purchased for the individuals covered by these contract arrangements.

API's pension plan's assets at December 31, 2018 and 2017 by asset category, are as follows:

(1) Represents investments in pooled funds. This is a method of investing whereby a portfolio of assets is built with the objective of moving in-line with liabilities. The assets are typically derivative instruments based on government bonds or instruments called swaps which are exposed to the same liability sensitivities (interest rates and inflation) as the pension liabilities.

During 2018, there were no changes to the HNH plans' Level 3 assets, and during 2017, the changes were as follows:

(12) During 2017, the WHX and JPS plans committed $5,000 to a fund which had a capital call for $2,000 due January 1, 2018, funded on December 29, 2017 and recorded as cash as of December 31, 2017. The fund's investment focus is on companies with substantial exposure in the Asian-Pacific region.

In addition to those on the table above, HNH had an additional unfunded commitment at December 31, 2017 totaling $10,000 for a separately managed investment account which had an all-cap value strategy.

Contributions

Employer contributions consist of funds paid from employer assets into a qualified pension trust account. HNH's funding policy is to contribute annually an amount that satisfies the minimum funding standards of the Employee Retirement Income Security Act. API's funding policy is to contribute monthly an amount that satisfies the API Plan's provisions to meet the level of assets needed to pay benefits in accordance with the statutory funding objectives required in the United Kingdom.

HNH expects to have required minimum annual contributions for 2019, 2020, 2021, 2022, 2023 and for the five years thereafter of $33,400, $34,700, $34,000, $36,700, $28,500 and $23,700, respectively. API expects to have required minimum annual contributions of $887 for 2019, 2020, 2021 and 2022, and $739 in 2023. Required future pension contributions are estimated based upon assumptions such as discount rates on future obligations, assumed rates of return on plan assets and legislative changes. Actual future pension costs and required funding obligations will be affected by changes in the factors and assumptions described in the previous sentence, as well as other changes such as any plan termination or other acceleration events.

Benefit Payments

Estimated future benefit payments for the pension plans over the next ten years are as follows:

Years	HNH Plans		API Plan

CAPITAL AND ACCUMULATED OTHER COMPREHENSIVE LOSS

Dec. 31, 2018

Stockholders' Equity Note [Abstract]

CAPITAL AND ACCUMULATED OTHER COMPREHENSIVE LOSS

CAPITAL AND ACCUMULATED OTHER COMPREHENSIVE LOSS

As of December 31, 2018, the Company had 25,294,003 Class A units (regular common units) outstanding.

Common Unit Repurchase Program

In December 2016, the Board of Directors of SPH GP approved the repurchase of up to an aggregate of 2,000,000 of the Company's common units. In November 2018, the Board of Directors approved the repurchase of up to an additional 1,000,000 of the Company's common units (collectively, with the December 2016 approval, "Repurchase Program"). The Repurchase Program supersedes and cancels, to the extent any amounts remain available, all previously approved repurchase programs. Any purchases made under the Repurchase Program will be made from time to time on the open market at prevailing market prices or in negotiated transactions off the market, in compliance with applicable laws and regulations. In connection with the Repurchase Program, the Company may enter into a stock purchase plan. The Repurchase Program has no termination date. The Company has purchased 1,583,841 common units for an aggregate price of approximately $27,160 under the Repurchase Program.

Incentive Award Plan

On May 24, 2018, the Company's unitholders approved the adoption of the Company's 2018 Incentive Award Plan ("2018 Plan"). The 2018 Plan provides equity-based compensation through the grant of options to purchase the Company's limited partnership units, unit appreciation rights, restricted units, phantom units, substitute awards, performance awards, other unit-based awards, and includes, as appropriate, any tandem distribution equivalent rights granted with respect to an award (collectively, "LP Units"). The 2018 Plan allows for issuance of up to 500,000 LP Units. As of December 31, 2018, no awards had been granted under the 2018 Plan.

Common Unit Dividend

On January 13, 2017, the Company paid dividends of approximately $3,923 to common unitholders of record as of January 3, 2017, excluding a consolidated affiliate. This special one-time cash dividend of $0.15 per common unit was declared on December 22, 2016. Any future determination to declare dividends on its common units will remain at the discretion of the Company's Board of Directors and will be dependent upon a number of factors, including the Company's results of operations, cash flows, financial position and capital requirements, among others.

Preferred Units

The 6.0% Series A preferred units, no par value ("SPLP Preferred Units"), which were issued in connection with the Steel Excel Inc. ("Steel Excel"), HNH and WebFinancial Holding Corporation ("WFHC") transactions discussed below, entitle the holders to a cumulative quarterly cash or in-kind (or a combination thereof) distribution. The Company declared cash distributions of approximately $11,750 and $4,700 to preferred unitholders for the years ended December 31, 2018 and 2017, respectively. The SPLP Preferred Units have a term of nine years and are redeemable at any time at the Company's option at a $25 liquidation value per unit, plus any accrued and unpaid distributions (payable in cash or SPLP common units, or a combination of both, at the Company's discretion). If redeemed in common units, the number of common units to be issued will be equal to the liquidation value per unit divided by the volume weighted-average price of the common units for 60 days prior to the redemption. In addition, the holders can require the Company to repurchase up to 1,600,000 of the SPLP Preferred Units, in cash on a pro rata basis, on the third anniversary of the original issuance date of February 7, 2017, reduced by any preferred units called for redemption by the Company, in cash on a pro rata basis, prior to that time.

The SPLP Preferred Units have no voting rights, except that holders of the preferred units have certain voting rights in limited circumstances relating to the election of directors following the failure to pay six quarterly distributions. The SPLP Preferred Units are recorded as a non-current liability, including accrued interest expense, on the Company's consolidated balance sheets as of December 31, 2018 and 2017 because they have an unconditional obligation to be redeemed for cash or by issuing a variable number of SPLP common units for a monetary value that is fixed and known at inception. Because the SPLP Preferred Units are classified as a liability, distributions thereon are recorded as a component of Interest expense in the Company's consolidated statements of operations. As of December 31, 2018 and 2017, there were 7,927,288 and 7,952,660 SPLP Preferred Units outstanding, respectively.

Steel Excel Transaction

On December 23, 2016, the Company entered into an Amended Agreement and Plan of Merger with a subsidiary of the Company and Steel Excel to make a tender offer to purchase any and all of the outstanding shares of common stock of Steel Excel not already owned by the Company or any of its affiliates. In exchange for each share of Steel Excel common stock, the Company offered 0.712 SPLP Preferred Units. The offer commenced on January 9, 2017 and expired on February 6, 2017. As a result of the completion of the offer, the Company issued approximately 2,500,000 SPLP Preferred Units with a fair value and liquidation value of $25.00 per SPLP Preferred Unit, or approximately $63,500, to Steel Excel shareholders and paid approximately $2,100 in cash for any remaining unvested restricted shares of Steel Excel. As a result of this transaction, the Company owns 100% of Steel Excel.

HNH Transaction

On June 26, 2017, the Company entered into an Agreement and Plan of Merger with a subsidiary of the Company and HNH to make a tender offer to purchase any and all of the outstanding shares of common stock of HNH not already owned by the Company or any of its affiliates. In exchange for each share of HNH common stock, the Company offered 1.484 SPLP Preferred Units. The offer expired on October 12, 2017, and as a result of the completion of the offer, the Company issued approximately 5,400,000 SPLP Preferred Units with a fair value of approximately $112,000 and liquidation value of approximately $135,000 to HNH shareholders. As a result of this transaction, the Company owns 100% of HNH.

WFHC Transactions

During 2018, the Company entered into purchase agreements with minority stockholders of its subsidiary, WFHC, pursuant to which the Company purchased shares of common and preferred stock of WFHC in exchange for aggregate consideration totaling approximately $20,680, comprised of cash of $13,708, 185,407 SPLP common units and 186,271 SPLP Preferred Units. As a result of these transactions, the Company now owns 100% of WFHC, as compared to 91.2% at December 31, 2017.

For each of the Steel Excel, HNH and WFHC transactions described above, in accordance with the accounting standard on consolidation, changes in a parent's ownership interest where the parent retains a controlling financial interest in its subsidiary were accounted for as equity transactions. The carrying amount of the acquired noncontrolling interests were eliminated to reflect the change in SPLP's ownership interest in each subsidiary, and the difference between the fair value of the consideration paid and the amount by which the noncontrolling interest was adjusted was recognized in Partners' capital.

On December 31, 2018, the Company entered into a contribution agreement with iGo, an equity method investee of the Company, in which the Company contributed its interest in its subsidiary, Kasco LLC ("Kasco"), in exchange for consideration consisting of 5,000,000 newly issued common shares of iGo and the assumption by iGo/Kasco of $15,000 of debt outstanding under the Credit Agreement (see Note 12 - "Long-Term Debt"). As a result of this transaction, the Company now owns 80.2% of iGo's common stock, and iGo became a consolidated subsidiary. As of December 31, 2018, iGo's assets and liabilities have been included in the Company's consolidated balance sheet, with a related noncontrolling interest of 19.8% of iGo's common stock.

(b) Net of a tax provision of approximately $329.

(c) For 2017, does not include the net unrealized gain on available-for sale securities of $811, the gain on derivative financial instruments of $55, cumulative translation adjustment gains of $932 and gains from the change in net pension and other post-retirement benefit obligations of $474, which are attributable to noncontrolling interests. For 2018, does not include the net unrealized gain on derivative financial instruments of $26 and cumulative translation adjustment of $(40), which are attributable to noncontrolling interests.

(d) Effective January 1, 2018 upon adoption of ASU 2016-01, a cumulative effect reclassification adjustment was made to remove the net unrealized gains and losses on equity securities from Accumulated other comprehensive loss and reclassify them to Partners' capital.

Incentive Unit Expense

Effective January 1, 2012, SPLP issued to the Manager partnership profits interests in the form of incentive units, a portion of which will be classified as Class C common units of SPLP upon the attainment of certain specified performance goals by SPLP, which are determined as of the last day of each fiscal year. If the performance goals are not met for a fiscal year, no portion of the incentive units will be classified as Class C common units for that year. The number of outstanding incentive units is equal to 100% of the common units outstanding, including common units held by non-wholly-owned subsidiaries. The performance goals and expense related to the classification of a portion of the incentive units as Class C units is measured on an annual basis, but is accrued on a quarterly basis. Accordingly, the expense accrued is adjusted to reflect the fair value of the Class C common units on each interim calculation date. In the event the cumulative incentive unit expense calculated quarterly or for the full year is an amount less than the total previously accrued, the Company records a negative incentive unit expense in the quarter when such over accrual is determined. The expense is recorded in Selling, general and administrative expenses in the Company's consolidated statements of operations. The Company recorded $0 and $9,021 of incentive unit expense for the years ended December 31, 2018 and 2017, respectively.

(a) Represents taxes at statutory rate on losses for which no tax benefit is recognizable by SPLP and certain of its subsidiaries which are taxed as pass-through entities. Such losses are allocable directly to SPLP's unitholders and taxed when realized.

The Act was enacted on December 22, 2017. The income tax effects of changes in tax laws are recognized in the period when enacted. The Act provides for numerous significant tax law changes and modifications with varying effective dates, which include reducing the U.S. federal corporate income tax rate from 35% to 21%, creating a territorial tax system (with a one-time mandatory repatriation tax on previously deferred foreign earnings) and allowing for immediate capital expensing of certain qualified property acquired and placed in service after September 27, 2017 and before January 1, 2023.

In response to the enactment of the Act in late 2017, the U.S. Securities and Exchange Commission issued Staff Accounting Bulletin No. 118 ("SAB 118") to address situations where the accounting is incomplete for certain income tax effects of the Act upon issuance of an entity's financial statements for the reporting period in which the Act was enacted. The measurement period allowed by SAB 118, in which the Company recorded an income tax benefit of $1,896 related to the one-time mandatory repatriation tax, closed during the fourth quarter of 2018. The prospects of supplemental legislation or regulatory processes to address uncertainties that arise because of the Act, or evolving technical interpretations of the tax law, may cause the Company's consolidated financial statements to be impacted in the future. The Company will continue to analyze the effects of the Act as subsequent guidance continues to emerge.

The Act also includes a provision to tax global intangible low-taxed income ("GILTI") of foreign subsidiaries. The FASB Staff Q&A Topic No. 5, Accounting for Global Intangible Low-Taxed Income, states that an entity can make an accounting policy election either to recognize deferred taxes for temporary differences that are expected to reverse as GILTI in future years or provide for the tax expense related to GILTI resulting from those items in the year the tax is incurred. We have elected to recognize the resulting tax on GILTI as a period expense in the period the tax is incurred.

Deferred income taxes result from temporary differences in the financial basis and tax basis of assets and liabilities. The amounts shown on the following table represent the tax effect of temporary differences between the consolidated tax return basis of assets and liabilities and the corresponding basis for financial reporting, as well as tax credit and operating loss carryforwards.

	December 31,

Deferred tax liabilities	2,225			3,007
	$	93,815		$	106,004

(a) The ability for certain subsidiaries to utilize net operating losses and other credit carryforwards may be subject to limitation upon changes in control.

(b) Certain subsidiaries of the Company establish valuation allowances when they determine, based on their assessment, that it is more likely than not that certain deferred tax assets will not be fully realized. This assessment is based on, but not limited to, historical operating results, uncertainty in projections of taxable income and other uncertainties that may be specific to a particular business.

At December 31, 2018, the Company's corporate subsidiaries had carryforwards of U.S. federal net operating losses ("NOLs") of approximately $397,046 that expire in 2020 through 2037. In addition, there are federal NOLs that can only be utilized by the corporate subsidiaries that generated the prior year losses, commonly called SRLY NOLs, totaling $199,240, which will expire in 2020 through 2037. The Company has a valuation allowance to reserve its deferred tax asset associated with the SRLY NOLs, and the addition of SRLY NOLs during 2018 from the consolidation of iGo is the principal reason for the increase in the valuation allowance during 2018. There is a capital loss carryforward in the amount of $34,815 that expires in 2021-2022. The deferred tax asset associated with this item has been fully reserved.

The Company's corporate subsidiaries have NOLs in foreign jurisdictions totaling $18,054 for which a valuation allowance to reserve the associated deferred tax asset has been established. There are NOLs in various states in which the subsidiaries operate. The amount totaled $21,213 and expires in 2019 through 2037. A valuation allowance has been established against a significant portion of the deferred tax asset associated with the state NOLs.

The Company's corporate subsidiaries have federal research and development credit carryforwards of $28,213 that expire in 2019 through 2029, and state research and development credit carryforwards of $20,683 for which a significant amount do not expire. The Company has a valuation allowance to reserve a significant portion of its deferred tax assets associated with the credit carryforwards.

At December 31, 2017, a valuation allowance was released against substantially all of one of the Company's corporate subsidiary's federal deferred tax assets (except for certain federal NOLs of a subsidiary company subject to limitations and the realized capital losses) as the Company concluded such assets were fully realizable. This assessment was primarily based on the restructuring of several business units that enabled operational efficiencies resulting in a more likely than not assertion to realize the majority of the federal deferred tax assets. The Company will continue to monitor the likelihood that it will be able to recover the deferred tax assets in the future. This determination includes objectively verifiable positive evidence that outweighs potential negative evidence.

Unrecognized Tax Benefits

U.S. GAAP provides that the tax effects from an uncertain tax position can be recognized in the consolidated financial statements only if the position is more likely than not of being sustained on audit, based on the technical merits of the position. The change in the amount of unrecognized tax benefits for 2018 and 2017 was as follows:

Balance at December 31, 2016	$	29,394
Additions for tax positions related to current year	32,684
Reductions due to lapsed statutes of limitations	(1,350		)
Balance at December 31, 2017	$	60,728
Additions for tax positions related to current year	977
Additions for tax positions related to prior years	1,413
Payments	(543		)
Reductions due to lapsed statutes of limitations and expiration of credits	(10,850		)
Balance at December 31, 2018	$	51,725

The Company's total gross unrecognized tax benefits were $51,725 and $60,728 at December 31, 2018 and 2017, respectively, of which $33,812, if recognized, would affect the provision for income taxes. In 2018, the Company settled certain state tax examinations resulting in a payment against the reserve of $543. In addition, the Company reversed $10,850 of reserves upon the expiration of the statutes of limitations with applicable taxing authorities and the expiration of time for utilizing certain credits for which a full reserve is maintained. The increase in unrecognized tax benefits in 2017 was primarily related to certain tax credits from prior years that may not be sustained on a more-likely-than-not basis. As of December 31, 2018, it is reasonably possible that unrecognized tax benefits may decrease by $1,103 in the next 12 months due to the expiration of statutes of limitations. The Company recognizes interest and penalties (if applicable) related to uncertain tax positions in its income tax provision in the consolidated statement of operations. For 2018 and 2017, the amount of such interest and penalties recognized was not significant.

The Company is subject to U.S. federal income tax, as well as income taxes in various domestic states and foreign jurisdictions in which the Company operated or formerly operated in. The Company is generally no longer subject to federal, state or local income tax examinations by tax authorities for any year prior to 2015, except as noted below. However, NOLs generated in prior years are subject to examination and potential adjustment by the taxing authorities upon their utilization in subsequent years' tax returns.

A corporate subsidiary of the Company is currently under examination by the Internal Revenue Service ("IRS") for the year 2015, which remains on-going. To date, the IRS has not notified the Company of any material adjustments resulting from the examination. With respect to the same corporate subsidiary, the IRS completed the examination for the year 2014, resulting in no adjustments to the original filing. The Company also settled an IRS examination of a corporate subsidiary's final pre-acquisition period filing, resulting in a small refund.

During 2018, the Company settled various state and local examinations for the years 2012, 2013 and 2015 at a total cost of $543, for which the Company was fully reserved. In addition, certain corporate subsidiaries are either currently under examination or have been notified of pending examinations for the years 2014 through 2016 by the State of New York.

The Company is not currently under tax examination in any foreign jurisdictions.

There were no transfers of securities among the various measurement input levels during the years ended December 31,

2018 or 2017.

The fair value of the Company's financial instruments, such as cash and cash equivalents, trade and other receivables and accounts payable, approximates carrying value due to the short-term maturities of these assets and liabilities. Carrying cost approximates fair value for long-term debt, which has variable interest rates.

The precious metal and commodity inventories associated with the Company's fair value hedges (see Note 13 - "Financial Instruments") are reported at fair value. Fair values of these inventories are based on quoted market prices on commodity exchanges and are considered Level 1 measurements. The derivative instruments that the Company purchases in connection with its precious metal and commodity inventories, specifically commodity futures and forward contracts, are also valued at fair value. The futures contracts are Level 1 measurements since they are traded on a commodity exchange. The forward contracts are entered into with a counterparty and are considered Level 2 measurements.

Following is a summary of changes in financial assets measured using Level 3 inputs:

(a) Unrealized gains and losses are recorded in Loss (income) of associated companies, net of taxes in the Company's consolidated statements of operations.

(b) Realized gains and losses on sale are recorded in Realized and unrealized losses (gains) on securities, net or Revenue in the Company's consolidated statements of operations, as are unrealized gains and losses incurred in 2018. In 2017, prior to the adoption of ASU 2016-01, unrealized gains and losses were recorded in AOCI.

Long-Term Investments - Valuation Techniques

The Company estimates the value of its investment in STCN preferred stock using a Monte Carlo simulation. Key inputs in this valuation include the trading price and volatility of STCN's common stock, the risk-free rate of return, as well as the dividend rate, conversion price and redemption date of the preferred stock. The Company estimates the value of another of its investments in an associated company primarily using a discounted cash flow method adjusted for additional information related to debt covenants, solvency issues and other related matters.

Marketable Securities and Other - Valuation Techniques

The Company uses the net asset value included in quarterly statements it receives in arrears from a venture capital fund to determine the fair value of such fund and determines the fair value of certain corporate securities and corporate obligations by incorporating and reviewing prices provided by third-party pricing services based on the specific features of the underlying securities. The fair value of the derivatives held by WebBank (see Note 13 - "Financial Instruments") represent the estimated amounts that WebBank would receive or pay to terminate the contracts at the reporting date and is based on discounted cash flows analyses that consider credit, performance and prepayment. Unobservable inputs used in the discounted cash flow analyses are: a constant prepayment rate of 7.01% to 35.85%, a constant default rate of 1.01% to 27.56% and a discount rate of 1.34% to 27.71%.

Assets Measured at Fair Value on a Nonrecurring Basis

The Company's non-financial assets and liabilities measured at fair value on a non-recurring basis include goodwill and other intangible assets, any assets and liabilities acquired in a business combination, or its long-lived assets written down to fair value. To measure fair value for such assets and liabilities, the Company uses techniques including an income approach, a market approach and/or appraisals (Level 3 inputs). The income approach is based on a discounted cash flow analysis and calculates the fair value by estimating the after-tax cash flows attributable to an asset or liability and then discounting the after-tax cash flows to a present value using a risk-adjusted discount rate. Assumptions used in the discounted cash flow analysis ("DCF") require the exercise of significant judgment, including judgment about appropriate discount rates and terminal values, growth rates and the amount and timing of expected future cash flows. The discount rates, which are intended to reflect the risks inherent in future cash flow projections, used in the DCF are based on estimates of the weighted-average cost of capital of a market participant. Such estimates are derived from analysis of peer companies and consider the industry weighted-average return on debt and equity from a market participant perspective. A market approach values a business by considering the prices at which shares of capital stock, or related underlying assets, of reasonably comparable companies are trading in the public market or the transaction price at which similar companies have been acquired. If comparable companies are not available, the market approach is not used.

Environmental and Litigation Matters

As discussed in more detail below, certain of the Company's subsidiaries have been designated as potentially responsible parties ("PRPs") by federal and state agencies with respect to certain sites with which they may have had direct or indirect involvement and as defendants in certain litigation matters. Most such legal proceedings and environmental investigations involve unspecified amounts of potential damage claims or awards, are in an initial procedural phase, involve significant uncertainty as to the outcome or involve significant factual issues that need to be resolved, such that it is not possible for the Company to estimate a range of possible loss. For matters that have progressed sufficiently through the investigative process such that the Company is able to reasonably estimate a range of possible loss, an estimated range of possible loss is provided, in excess of the accrued liability (if any) for such matters. Any estimated range is or will be based on currently available information and involves elements of judgment and significant uncertainties. Any estimated range of possible loss may not represent the Company's maximum possible loss exposure. The circumstances of such legal proceedings and environmental investigations will change from time to time, and actual results may vary significantly from the current estimate. For current proceedings not specifically reported below, management does not anticipate that the liabilities, if any, arising from such proceedings would have a material effect on the financial position, liquidity or results of operations of the Company.

The environmental claims are in various stages of administrative or judicial proceedings and include demands for recovery of past governmental costs, and for future investigations and remedial actions. In many cases, the dollar amounts of the claims have not been specified and, with respect to a number of the PRP claims, have been asserted against a number of other entities for the same cost recovery or other relief as was asserted against certain of the Company's subsidiaries. The Company accrues costs associated with environmental and litigation matters on an undiscounted basis, when they become probable and reasonably estimable. As of December 31, 2018, on a consolidated basis, the Company has recorded liabilities of $14,960 in Accrued liabilities on the consolidated balance sheet, which represent the current estimate of environmental remediation liabilities as well as reserves related to the litigation matters discussed below. Expenses relating to these costs, and any recoveries, are included in Selling, general and administrative expenses in the Company's consolidated statements of operations. In addition, the Company has insurance coverage available for several of these matters and believes that excess insurance coverage may be available as well. Estimates of the Company's liability for remediation of a particular site and the method and ultimate cost of remediation require a number of assumptions that are inherently difficult to make, and the ultimate outcome may be materially different from current estimates.

Environmental Matters

Certain HNH subsidiaries have existing and contingent liabilities relating to environmental matters, including costs of remediation, capital expenditures, and potential fines and penalties relating to possible violations of national and state environmental laws. Those subsidiaries have remediation expenses on an ongoing basis, although such costs are continually being readjusted based upon the emergence of new techniques and alternative methods. HNH recorded liabilities of approximately $13,211 related to estimated environmental remediation costs as of December 31, 2018. HNH may have insurance coverage available for certain of these matters.

Included among these liabilities, certain HNH subsidiaries have been identified as PRPs under the Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA") or similar state statutes at sites and are parties to administrative consent orders in connection with certain properties. Those subsidiaries may be subject to joint and several liabilities imposed by CERCLA on PRPs. Due to the technical and regulatory complexity of remedial activities and the difficulties attendant in identifying PRPs and allocating or determining liability among them, the subsidiaries are unable to reasonably estimate the ultimate cost of compliance with such laws.

Based upon information currently available, the HNH subsidiaries do not expect that their respective environmental costs, including the incurrence of additional fines and penalties, if any, will have a material adverse effect on them or that the resolution of these environmental matters will have a material adverse effect on the financial position, results of operations or cash flows of such subsidiaries or the Company, but there can be no such assurances. The Company anticipates that the subsidiaries will pay any such amounts out of their respective working capital, although there is no assurance that they will have sufficient funds to pay them. In the event that a HNH subsidiary is unable to fund its liabilities, claims could be made against its respective parent companies for payment of such liabilities.

The sites where certain HNH subsidiaries have environmental liabilities include the following:

HNH has been working with the Connecticut Department of Energy and Environmental Protection ("CTDEEP") with respect to its obligations under a 1989 consent order that applies to a property in Connecticut that HNH sold in 2003 ("Sold Parcel") and an adjacent parcel ("Adjacent Parcel") that together comprise the site of a former HNH manufacturing facility. The remaining remediation, monitoring and regulatory administrative costs for the Sold Parcel are expected to approximate $100. With respect to the Adjacent Parcel, an ecological risk assessment has been completed and the results, along with proposed cleanup goals, were submitted in the second quarter of 2016 to the CTDEEP for their review and approval. An upland work plan to investigate the upland portion of the parcel was submitted in the third quarter of 2017 to the CTDEEP and was approved in March 2018. That investigation work started in the second quarter of 2018 and was completed in the fourth quarter of 2018. Additional investigatory work could be required dependent upon CTDEEP requirements. Investigation of the wetlands portion is also expected to start in the first half of 2019, pending regulatory approvals and setting goals for the entire parcel. The total remediation costs for the Adjacent Parcel cannot be reasonably estimated at this time. Based on the current stage of the investigation at this time, the Company estimates that it is reasonably possible that it may incur aggregate losses over a period of several years, above its accrued liability, in a range of $2,000 to $6,000. Due to the uncertainties, there can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of the Company.

In 1986, Handy & Harman Electronic Materials Corporation ("HHEM"), a subsidiary of HNH, entered into an administrative consent order ("ACO") with the New Jersey Department of Environmental Protection ("NJDEP") with regard to certain property that it purchased in 1984 in New Jersey. The ACO involves investigation and remediation activities to be performed with regard to soil and groundwater contamination. HHEM is actively remediating the property and is continuing to investigate effective methods for achieving compliance with the ACO. HHEM anticipates entering into discussions with the NJDEP to address that agency's potential natural resource damage claims, the timing and ultimate scope and cost of which cannot be estimated at this time. Pursuant to a settlement agreement with the former owner/operator of the site, the responsibility for site investigation and remediation costs, as well as any other costs, as defined in the settlement agreement, related to or arising from environmental contamination on the property (collectively, "Costs") are contractually allocated 75% to the former owner/operator and 25% jointly to HHEM and HNH, all after having the first $1,000 paid by the former owner/operator. As of December 31, 2018, total investigation and remediation costs of approximately $7,500 and $2,400 have been expended by the former owner/operator and HHEM, respectively, in accordance with the settlement agreement. Additionally, HHEM had been reimbursed indirectly through insurance coverage for a portion of the Costs for which HHEM is responsible. While the primary insurance reimbursement ceased, HHEM believes that there is additional excess insurance coverage, which it is currently pursuing. There is no assurance that the former owner/operator or guarantors will continue to timely reimburse HHEM for expenditures and/or will be financially capable of fulfilling their obligations under the settlement agreement and the guaranties. There is no assurance that there will be any additional insurance reimbursement. A reserve of approximately $1,800 has been established for HHEM's expected 25% share of anticipated costs at this site, which is based upon the recent selection of a final remedy, on-going operations and maintenance, additional investigations and monitored natural attenuation testing over the next 30 years. There can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of HHEM, HNH or the Company.

HNH's subsidiary, SL Industries, Inc. ("SLI"), may incur environmental costs in the future as a result of the past activities of its former subsidiary, SL Surface Technologies, Inc. ("SurfTech"), in Pennsauken, New Jersey ("Pennsauken Site"), in Camden, New Jersey and at its former subsidiary, SGL Printed Circuits in Wayne, New Jersey. At the Pennsauken Site, in 2013, SLI reached an agreement with both the U.S. Department of Justice and the U.S. Environmental Protection Agency ("EPA") related to its liability and entered into a Consent Decree which governs the agreement. SLI has completed the remediation as required by the Consent Decree and has paid EPA a fixed sum for its past oversight costs. Separate from the Consent Decree, in December 2012, the NJDEP made a settlement demand of $1,800 for past and future cleanup and removal costs and natural resource damages ("NRD"). To avoid the time and expense of litigating the matter, SLI offered to pay approximately $300 to fully resolve the claim presented by the State of New Jersey ("State"). SLI's settlement offer was rejected. On December 6, 2018, the State filed a complaint against SLI related to its operations at the Pennsauken Site. The State is seeking treble damages and attorneys' fees, NRD for loss of use of groundwater, as well as a request for relief that SLI pay all cleanup and removal costs that the State has incurred and will incur at the Pennsauken Site. While the State did not specifically identify its alleged damages in the complaint, the State has identified $3,661 in past costs through December 11, 2018. SLI intends to assert all legal and procedural defenses available to it. Although the final scope and cost of this claim cannot be verified at this time, we estimate that it is reasonably possible that we may incur an aggregate loss in a range of $300 to $3,661. Given the State's other generally-alleged damages, however, there can be no assurance that there will not be potential additional costs associated with the Pennsauken Site, which cannot be reasonably estimated at this time. Accordingly, there can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of SLI, HNH or the Company.

SLI reported soil contamination and a groundwater contamination in 2003 from the SurfTech site located in Camden, New Jersey. Substantial investigation and remediation work has been completed under the direction of the Licensed Site Remediation Professional ("LSRP") for the site. Additional remediation initiated during the fourth quarter of 2018 is expected to continue into the first quarter of 2019 and post-remediation groundwater monitoring conducted thereafter. A full-scale groundwater bioremediation is expected to be implemented during the first quarter of 2019 following the remediation mentioned above. A reserve of $2,500 has been established for anticipated costs at this site, but there can be no assurance that there will not be potential additional costs associated with the site which cannot be reasonably estimated at this time. Accordingly, there can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of SLI, HNH or the Company.

SLI is currently participating in environmental assessment and cleanup at a commercial facility located in Wayne, New Jersey. Contaminated soil and groundwater has undergone remediation with the NJDEP and LSRP oversight, but contaminants of concern in groundwater and surface water, which extend off-site, remain above applicable NJDEP remediation standards. A reserve of approximately $1,100 has been established for anticipated costs, but there can be no assurance that there will not be potential additional costs associated with the site, which cannot be reasonably estimated at this time. Accordingly, there can be no assurance that the resolution of this matter will not be material to the financial position, results of operations or cash flows of SLI, HNH or the Company.

BNS LLC, a wholly-owned subsidiary of the BNS Holdings Liquidating Trust, has been named as a PRP at one previously disclosed site. Based upon information currently available, BNS Holdings Liquidating Trust does not expect that its environmental costs or that the resolution of this environmental matter will have a material adverse effect on the financial position, results of operations or cash flows of the Company, and although there can be no such assurances to this effect, the Company will provide further updates as to this site only if that assessment changes.

Litigation Matters

On December 8, 2017, a putative stockholder class action, captioned Sciabacucchi v. DeMarco, et al., was filed in the Court of Chancery of the State of Delaware by a purported former stockholder of HNH challenging the Company's acquisition, through a subsidiary, of all of the outstanding shares of common stock of HNH not already owned by the Company or any of its affiliates. On June 15, 2018, this action was consolidated with a second putative stockholder class action filed April 30, 2018, and captioned John Levin v. DeMarco, et al. The consolidated action names as defendants the former members of the HNH board of directors, the Company and SPH GP, and alleges, among other things, that the defendants breached their fiduciary duties to the former public stockholders of HNH in connection with the aforementioned acquisition. The complaint seeks, among other relief, unspecified monetary damages, attorneys' fees and costs. On July 5, 2018, the Court granted plaintiff's motion for class certification. The Company is vigorously defending itself against these claims; however, the outcome of this matter is uncertain.

A subsidiary of BNS Holdings Liquidating Trust ("BNS Sub") has been named as a defendant in multiple alleged asbestos-related toxic-tort claims filed over a period beginning in 1994 through December 31, 2018. In many cases these claims involved more than 100 defendants. Of the claims settled, the average settlement was less than $3. There remained approximately 30 pending asbestos claims as of December 31, 2018. BNS Sub believes it has significant defenses to any liability for toxic-tort claims on the merits. None of these toxic-tort claims has gone to trial and, therefore, there can be no assurance that these defenses will prevail. BNS Sub has insurance policies covering asbestos-related claims for years beginning 1974 through 1988. BNS Sub annually receives retroactive billings or credits from its insurance carriers for any increase or decrease in claims accruals as claims are filed, settled or dismissed, or as estimates of the ultimate settlement costs for the then-existing claims are revised. As of both December 31, 2018 and 2017, BNS Sub has accrued $1,349 relating to the open and active claims against BNS Sub. This accrual includes the amount of unpaid retroactive billings submitted to the Company by the insurance carriers and also the Company's best estimate of the likely costs for BNS Sub to settle these claims outside the amounts funded by insurance. There can be no assurance that the number of future claims and the related costs of defense, settlements or judgments will be consistent with the experience to-date of existing claims and that BNS Sub will not need to significantly increase its estimated liability for the costs to settle these claims to an amount that could have a material effect on the consolidated financial statements.

In the ordinary course of our business, we are subject to other periodic lawsuits, investigations, claims and proceedings, including, but not limited to, contractual disputes, employment, environmental, health and safety matters, as well as claims associated with our historical acquisitions and divestitures. There is insurance coverage available for many of the foregoing actions. Although we cannot predict with certainty the ultimate resolution of lawsuits, investigations, claims and proceedings asserted against us, we do not believe any currently pending legal proceeding to which we are a party will have a material adverse effect on our business, prospects, financial condition, cash flows, results of operations or liquidity.

Regulatory Matters [Abstract]

REGULATORY MATTERS

REGULATORY MATTERS

WebBank is subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain actions by regulators that, if undertaken, could have a direct material effect on WebBank's financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, WebBank must meet specific capital guidelines that involve quantitative measures of its assets, liabilities and certain off-balance sheet items as calculated under regulatory accounting practices. WebBank's capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings and other factors.

In July 2013, the Federal Deposit Insurance Corporation approved the final rules implementing the Basel Committee on Banking Supervision's capital guidelines for U.S. banks ("Basel III"). Under the final rules, which began for WebBank on January 1, 2015 and have been fully implemented as of January 1, 2019, minimum requirements increased for both the quantity and quality of capital held by WebBank. The rules include a new common equity Tier 1 capital to risk-weighted assets ratio ("CET1 Ratio") of 4.5% and a capital conservation buffer of 2.5% of risk-weighted assets, which as fully phased-in, effectively results in a minimum CET1 Ratio of 7.0%. Basel III raised the minimum ratio of Tier 1 capital to risk-weighted assets from 4.0% to 6.0% (which, with the capital conservation buffer, effectively results in a minimum Tier 1 capital ratio of 8.5% as fully phased-in), effectively results in a minimum total capital to risk-weighted assets ratio of 10.5% (with the capital conservation buffer fully phased-in), and requires a minimum leverage ratio of 4.0%. Basel III also made changes to risk weights for certain assets and off-balance-sheet exposures. WebBank expects that its capital ratios under Basel III will continue to exceed the well capitalized minimum capital requirements, and such amounts are disclosed in the table below:

(a) Effective January 1, 2018 upon adoption of ASU 2016-01, unrealized gains or losses on equity securities are no longer recorded in AOCI on the consolidated balance sheet, but are instead recognized in Realized and unrealized losses (gains) on securities, net in the consolidated statement of operations. Realized and unrealized losses (gains) on securities, net totaled $62,586 for the full year of 2018 and $14,557 for the fourth quarter of 2018, as compared with $(790) for the full year of 2017 and $45 for the fourth quarter of 2017.

(b) The Company recorded asset impairment charges of approximately $8,108 in the fourth quarter of 2018, primarily related to intangible assets in the Diversified Industrial segment (See Note 5 - "Divestitures and Asset Impairment Charges").

(c) The Company recorded asset impairment charges of approximately $2,028 in the fourth quarter of 2017, primarily related to an other-than-temporary impairment on a certain available-for-sale security (see Note 5 - "Divestitures and Asset Impairment Charges"). In addition, the Act was enacted in the fourth quarter of 2017, and in connection therewith, the Company recorded income tax expense of $56,552 from the remeasurement of deferred tax balances. During 2017, the Company recorded an income tax benefit of $44,681 associated with the reversal of its deferred tax valuation allowances at certain subsidiaries, which primarily impacted the fourth quarter (see Note 16 - "Income Taxes").

Subsequent Events [Abstract]

SUBSEQUENT EVENTS

SUBSEQUENT EVENT

On February 28, 2019, the Company entered into a 7.50% convertible senior note due 2024 ("New Note") with STCN, whereby the Company will loan $14,940 to STCN. STCN will use the proceeds plus cash on hand to redeem at maturity its 5.25% convertible senior notes ("Steel Connect Notes"), which will mature on March 1, 2019. The Company holds $14,940 in aggregate principal amount of such Steel Connect Notes at December 31, 2018, which are further discussed in Note 10 - "Investments." The New Note is convertible into shares of STCN's common stock at an initial conversion rate of 421.2655 shares of common stock per $1,000 principal amount of the New Note (which is equivalent to an initial conversion price of approximately $2.37 per share), subject to adjustment upon the occurrence of certain events.

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)

12 Months Ended

Dec. 31, 2018

Accounting Policies [Abstract]

Use of Estimates in Preparation of Consolidated Financial Statements

Use of Estimates in Preparation of Consolidated Financial Statements

The Company's consolidated financial statements are prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP"). The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amount of assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses, and related disclosure of contingent assets and liabilities during the reporting period. The more significant estimates include: (1) the valuation allowances for trade and other receivables, loans receivable and inventories; (2) the valuation of goodwill, indefinite-lived intangible assets, long-lived assets and associated companies; (3) deferred tax assets; (4) environmental liabilities; (5) fair value of derivatives; (6) post-employment benefit liabilities; (7) estimates and assumptions used in the determination of fair value of certain securities; and (8) estimates of loan losses. Actual results may differ from the estimates used in preparing the consolidated financial statements; and, due to substantial holdings in and/or restrictions on certain investments, the value that may be realized could differ from the estimated fair value.

Cash and Cash Equivalents

Cash and Cash Equivalents

Cash and cash equivalents include cash and deposits in depository institutions, financial institutions and banks.

he Company considers all highly liquid debt instruments with maturities of three months or less when purchased to be cash equivalents. Cash and cash equivalents include qualifying money market funds and exclude amounts where availability is restricted by loan agreements or other contractual provisions. Cash equivalents are stated at cost, which approximates market value. There is a significant concentration of cash that, during the periods presented, exceeded the federal deposit insurance limits and exposed the Company to credit risk.

Restricted Cash

Restricted Cash

Restricted cash at December 31, 2018 and 2017 primarily represents cash collateral for certain short sales of corporate securities (see Note 13 - "Financial Instruments" for additional information).

Marketable Securities and Long-Term Investments

Marketable Securities and Long-Term Investments

Marketable securities consist of short-term deposits, corporate debt and equity instruments, and mutual funds. The Company classifies its marketable securities as current assets based on the nature of the securities and their availability for use in current operations. Long-term investments consist of equity securities and certain associated company investments. Held-to-maturity securities are classified in Other non-current assets. SPLP determines the appropriate classifications of its investments at the acquisition date and re-evaluates the classifications at each balance sheet date.

• Since the Company adopted Accounting Standards Update No. ("ASU") 2016-01 effective January 1, 2018, available-for-sale equity securities are now reported at fair value, with unrealized gains and losses recognized in Realized and unrealized losses (gains) on securities, net in the consolidated statement of operations. In 2017, prior to the adoption of ASU 2016-01, such unrealized gains and losses were recognized in Accumulated other comprehensive income (loss) ("AOCI") as a separate component of SPLP's Partners' capital.

• Available-for-sale debt securities are reported at fair value, with unrealized gains and losses recognized in AOCI as a separate component of SPLP's Partners' capital in both 2018 and 2017.

• Associated companies represent equity method investments in companies where our ownership is between 20% and 50% of the outstanding equity and the Company has the ability to exercise influence, but not control, over the investee. For equity method investments where the fair value option has been elected, unrealized gains and losses are reported in the Company's consolidated statements of operations as part of Loss (income) of associated companies, net of tax. For the equity method investments where the fair value option has not been elected, SPLP records the investment at cost and subsequently increases or decreases the investment by its proportionate share of the net income or loss and other comprehensive income or loss of the investee.

• Held-to-maturity securities are recorded at amortized cost, adjusted for the amortization or accretion of premiums or discounts.

Dividend and interest income is recognized when earned. Realized gains and losses on marketable securities and long-term investments are included in earnings and are derived using the specific-identification method. Commission expense is recorded as a reduction of sales proceeds on investment sales. Commission expense on purchases is included in the cost of investments on the Company's consolidated balance sheets.

Other Than Temporary Impairment

Other Than Temporary Impairment

If the Company believes a decline in the market value of any available-for-sale debt security, equity method or held-to-maturity security below cost is other than temporary, a loss is charged to earnings, which establishes a new cost basis for the security. Impairment losses are included in Asset impairment charges in the Company's consolidated statements of operations. SPLP's determination of whether a security is other than temporarily impaired incorporates both quantitative and qualitative information. The Company considers a number of factors including, but not limited to, the length of time and the extent to which the fair value has been less than cost, the length of time expected for recovery, the financial condition of the issuer, the reason for the decline in fair value, changes in fair value subsequent to the balance sheet date, the ability and intent to hold investments to maturity, and other factors specific to the individual investment.

Specifically, for held-to-maturity securities, the Company considers whether it plans to sell the security or it is more-likely-than-not that it will be required to sell the security before recovery of its amortized cost. The credit component of an other-than-temporary impairment loss is recognized in earnings and the non-credit component is recognized in AOCI in situations where the Company does not intend to sell the security and it is more likely-than-not that the Company will not be required to sell the security prior to recovery. If there is an other-than-temporary impairment in the fair value of any individual security classified as held-to-maturity, the Company writes down the security to fair value with a corresponding credit loss portion charged to earnings, and the non-credit portion being charged to AOCI. SPLP's assessment involves a high degree of judgment and accordingly, actual results may differ materially from those estimates and judgments.

Trade and Accounts Receivable and Allowance for Doubtful Accounts

Trade Receivables and Allowance for Doubtful Accounts

The Company recognizes bad debt expense through an allowance account using estimates based primarily on management's evaluation of the financial condition of the customer, historical experience, credit quality, whether any amounts are currently past due, the length of time accounts may be past due, previous loss history and management's determination of a customer's current ability to pay its obligations. Trade receivable balances are charged off against the allowance when it is determined that the receivables will not be recovered, and payments subsequently received on such receivables are credited to recovery of accounts written off. The Company believes that the credit risk with respect to trade receivables is limited due to this credit evaluation process.

Loans Receivable, Including Loans Held for Sale / Loan Impairment and Allowance for Loan Losses

Loans Receivable, Including Loans Held for Sale

WebBank's loan activities include several lending arrangements with companies where it originates credit card and other loans for consumers and small businesses. These loans are classified as Loans receivable and are typically sold after origination. As part of these arrangements, WebBank earns fees that are recorded in non-interest income. Fees earned from these lending arrangements are recorded as fee income. WebBank also purchases participations in commercial and industrial loans through loan syndications. Loans that management has the intent and ability to hold for the foreseeable future or until maturity or pay-off generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, the allowance for loan losses ("ALLL"), and any deferred fees or costs on originated loans. Interest income is accrued on the unpaid principal balance. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield over the estimated life of the loan.

Through a loan program, merchants can borrow a certain percentage of their annual payment volume and are charged a fixed fee for the loan, which targets an annual percentage rate based on the overall credit assessment of the merchant. Loans are repaid through a fixed percentage of the merchant's future payment volume. The fee is fixed at the time the loan is extended. The fixed fee is amortized to interest income based on the amount repaid over the repayment period. We estimate the repayment period based on the merchant's payment processing history. There is no stated interest rate. There is a general requirement that at least 10% of the original amount of the loan plus the fixed fee must be repaid every 90 days. We calculate the repayment rate of the merchant's future payment volume so that repayment of the loan or advance and fixed fee is expected to generally occur within 9 to 12 months from the date of the loan or advance.

Loans held for sale are carried at the lower of cost or estimated market value in the aggregate. A valuation allowance is recorded when cost exceeds fair value based on our determination at the time of reclassification and periodically thereafter. Gains and losses are recorded in noninterest income based on the difference between sales proceeds and carrying value and impairments from reductions in carrying value.

Loans are reported as past due when either principal or interest is due and unpaid for a period of 30 days or more. The accrual of interest on loans is generally discontinued at the time the loan is 90 to 180 days delinquent, depending on the type of loan, unless the loan is well-secured and in process of collection. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest is considered doubtful.

All interest accrued but not collected for loans that are placed on nonaccrual or charged off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Loan Impairment and Allowance for Loan Losses

A loan is considered impaired when, based on current information and events, it is probable that WebBank will be unable to collect all amounts due according to the contractual terms of the loan agreement, including scheduled interest payments. When a loan has been identified as being impaired, the amount of impairment is measured based on the present value of expected future cash flows discounted at the loan's effective interest rate or, when appropriate, the loan's observable fair value or the fair value of the collateral (less any selling costs) if the loan is collateral-dependent. If the measurement of the impaired loan is less than the recorded investment in the loan (including accrued interest, net of deferred loan fees or costs and unamortized premium or discount), an impairment is recognized by creating or adjusting an existing allocation of the ALLL, or by charging down the loan to its value determined in accordance with U.S. GAAP.

The ALLL is established as losses are estimated to have occurred through a provision for loan losses charged to earnings. Loan losses are charged against the allowance when the uncollectability of a loan or receivable balance is confirmed. Subsequent recoveries, if any, are credited to the allowance. The ALLL is evaluated on a regular basis and is based upon a periodic review of the collectability of the amounts due in light of historical experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower's ability to repay, estimated value of any underlying collateral and prevailing economic conditions. This evaluation is inherently subjective as it requires estimates that are susceptible to significant revision as more information becomes available. The allowance consists of specific and general components. The specific component relates to loans that are classified as doubtful, substandard or loss. For such loans that are classified as impaired, an allowance is established when the discounted cash flows (or collateral value or observable market price) of the impaired loan is lower than the carrying value of that loan. The general component covers non-classified loans and is based on historical loss experience and is adjusted for qualitative factors to cover uncertainties that could affect the estimate of probable losses. The ALLL is increased by charges to income and decreased by charge-offs (net of recoveries). The periodic evaluation of the adequacy of the allowance is based on WebBank's past loss experience, known and inherent risks in the portfolio, adverse situations that may affect the debtor's ability to repay, the estimated value of any underlying collateral and current economic conditions.

Inventories

Inventories

Inventories are generally stated at the lower of cost (determined by the first-in, first-out method or average cost method) or market. Cost is determined by the last-in, first-out ("LIFO") method for certain precious metal inventory held in the U.S., and remaining precious metal inventory is primarily carried at fair value. For precious metal inventory, no segregation among raw materials, work in process and finished products is practicable. For other inventory, the cost of work in process and finished products comprises the cost of raw materials, direct labor and overhead costs attributable to the production of inventory.

Non-precious metal inventories are evaluated for estimated excess and obsolescence based upon assumptions about future demand and market conditions, and are adjusted accordingly. If actual market conditions are less favorable than those projected, future write-downs may be required.

Goodwill and Other Intangible Assets, Net

Goodwill and Other Intangible Assets, Net

Goodwill, which is not amortized, represents the difference between the purchase price and the fair value of identifiable net assets acquired in a business combination. Goodwill is reviewed for impairment indicators throughout the year and tested for impairment annually in the fourth quarter. An entity can choose between two testing approaches:

a. Step 0 or Qualitative approach - An entity may assess qualitative factors to determine whether it is more likely than not (that is, a likelihood of more than 50 percent) that the fair value of a reporting unit is less than its carrying amount, including goodwill. In evaluating whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount, an entity should assess relevant events and circumstances. Examples of such events and circumstances would include pertinent macroeconomic conditions, industry and market considerations, overall financial performance and other factors.

An entity has an unconditional option to bypass this qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period.

b. Step 1 or Quantitative approach - The fair value of a reporting unit is calculated and compared with its carrying amount. There are several methods that may be used to estimate a reporting unit's fair value, including the income approach, market approach and/or cost approach. If the fair value of a reporting unit exceeds its carrying amount, there is no indication of impairment and further testing is not required. If the carrying amount of a reporting unit exceeds its fair value, then a second step of testing is required ("Step 2"). The second step of the goodwill impairment test compares the implied fair value of the reporting unit's goodwill with the carrying amount of that goodwill.

For 2018, the Company utilized a qualitative approach for all of its reporting units, except for the Packaging business within its Diversified Industrial segment. Based on its qualitative assessment, the Company does not believe that it is more likely than not that the fair value of any of its reporting units tested under this approach is less than its carrying value. The Company performed a quantitative assessment of goodwill associated with its Packaging business due to a decline in market conditions and lower demand for certain of the Packaging business' product lines. The assessment was based on a combination of income and market approaches to estimate the fair value of the reporting unit, which indicated that the fair value of this reporting unit exceeded its carrying value. Significant assumptions used in the discounted cash flow analysis included expected future earnings and cash flows, which are based on management's current expectations, as well as the related risk-adjusted discount rate used to estimate fair value. There were no goodwill impairment charges recorded as a result of these assessments. For 2017, the Company utilized a qualitative approach for all of its reporting units to assess goodwill, and there were no goodwill impairment charges recorded as a result of the assessment.

Other intangible assets with indefinite lives are not amortized, while other intangible assets with finite lives are amortized over their estimated useful lives. Intangible assets with finite lives are reviewed for impairment when events or changes in circumstances indicate that the carrying amount may not be recoverable (see "Long-Lived Asset Testing" below).

Intangible assets with indefinite lives, which are only within the Diversified Industrial segment, are tested for impairment at least annually, or when events or changes in circumstances indicate that it is more likely than not that the asset is impaired. Companies can use the same two testing approaches for indefinite-lived intangibles as for goodwill. For 2018 and 2017, the Company utilized a qualitative approach to assess its intangible assets with indefinite lives, and the results indicated no impairment in either of these years.

Derivatives

Derivatives

The Company uses various hedging instruments to reduce the impact of changes in precious metal prices and the effect of foreign currency fluctuations. In accordance with Accounting Standards Codification ("ASC") 815, Derivatives and Hedging, these instruments are recorded as either fair value hedges, economic hedges, cash flow hedges or derivatives with no hedging designation.

Precious Metals

The Company's precious metal and commodity inventories are subject to market price fluctuations. The Company enters into commodity futures and forward contracts to mitigate the impact of price fluctuations on its precious and certain non-precious metal inventories that are not subject to fixed price contracts. The Company's hedging strategy is designed to protect it against normal volatility; therefore, abnormal price changes in these commodities or markets could negatively impact the Company's earnings.

Fair Value Hedges. The fair values of these derivatives are recognized as derivative assets and liabilities on the Company's consolidated balance sheets. The net change in fair value of the derivative assets and liabilities, and the change in the fair value of the underlying hedged inventory, are recognized in the Company's consolidated statements of operations, and such amounts principally offset each other due to the effectiveness of the hedges. The fair value hedges are associated primarily with the Company's precious metal inventory carried at fair value.

Economic Hedges. As these derivatives are not designated as accounting hedges under ASC 815, they are accounted for as derivatives with no hedge designation. The derivatives are marked to market, and both realized and unrealized gains and losses are recorded in current period earnings in the Company's consolidated statements of operations. The economic hedges are associated primarily with the Company's precious metal inventory valued using the LIFO method.

Foreign Currency Forward Contracts

The Company enters into foreign currency forward contracts to hedge certain of its receivables and payables denominated in other currencies. In addition, the Company enters into foreign currency forward contracts to hedge the value of certain of its future sales and the value of its future purchases denominated in other currencies. The forward contracts that are used to hedge the risk of foreign exchange movement on its receivables and payables are accounted for as fair value hedges under ASC 815. The fair values of these derivatives are recognized as derivative assets and liabilities on the Company's consolidated balance sheets. The net change in fair value of the derivative assets and liabilities are recognized in the Company's consolidated statements of operations. The forward contracts that are used to hedge the value of the Company's future sales and purchases are accounted for as cash flow hedges in accordance with ASC 815. These hedges are fully effective and accordingly, the changes in fair value are recorded in AOCI and, at maturity, any gain or loss on the forward contract is reclassified from AOCI into the Company's consolidated statements of operations.

WebBank - Derivative Financial Instruments

WebBank's derivative financial instruments represent on-going economic interests in loans made after they are sold. These derivatives are carried at fair value on a gross basis in Other non-current assets on the Company's consolidated balance sheet. Gains and losses resulting from changes in fair value of these derivative instruments are accounted for in the Company's consolidated statements of operations in Financial services revenue. Fair value represents the estimated amounts that WebBank would receive at the reporting date based on a discounted cash flow model for the same or similar instruments. WebBank does not enter into derivative contracts for speculative or trading purposes.

Property, Plant and Equipment, Net / Long-Lived Asset Testing

Property, Plant and Equipment, Net

Property, plant and equipment is recorded at cost. Depreciation of property, plant and equipment is recorded principally on the straight line method over the estimated useful lives of the assets, which range as follows: machinery & equipment 3 to 15 years and buildings & improvements 10 to 30 years. Leasehold improvements are amortized over the shorter of the terms of the related leases or the estimated useful lives of the improvements. Interest cost is capitalized for qualifying assets during the assets' acquisition period. Maintenance and repairs are charged to expense, and renewals and betterments are capitalized. Gain or loss on dispositions is recorded in Other (income) expense, net.

Long-Lived Asset Testing

The Company estimates the depreciable lives of property, plant and equipment, and reviews long-lived assets for impairment whenever events, or changes in circumstances, indicate the carrying amount of such assets may not be recoverable. If the carrying values of the long-lived assets exceed the sum of the undiscounted cash flows, an impairment charge is recognized in the amount by which the carrying values exceeds their fair values. The Company performs such assessments at the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities, which is generally at the plant level, operating company level or the reporting unit level, dependent on the level of interdependencies in the Company's operations.

The Company considers various factors in determining whether an impairment test is necessary, including among other things: a significant or prolonged deterioration in operating results and projected cash flows; significant changes in the extent or manner in which assets are used; technological advances with respect to assets which would potentially render them obsolete; the Company's strategy and capital planning; and the economic climate in the markets it serves. When estimating future cash flows and if necessary, fair value, the Company makes judgments as to the expected utilization of assets and estimated future cash flows related to those assets. The Company considers historical and anticipated future results, general economic and market conditions, the impact of planned business and operational strategies and other information available at the time the estimates are made. The Company believes these estimates are reasonable; however, changes in circumstances or conditions could have a significant impact on its estimates, which might result in material impairment charges in the future.

Business Combinations

Business Combinations

When the Company acquires a business, it allocates the purchase price to the assets acquired, liabilities assumed and any noncontrolling interests based on their fair values at the acquisition date. Significant judgment may be used to determine these fair values including the use of appraisals, discounted cash flow models, market value for similar purchases or other methods applicable to the circumstances. The assumptions and judgments made by the Company when recording business combinations will have an impact on reported results of operations in the future.

Revenue Recognition

Revenue Recognition

Diversified Industrial and Energy Segments

In May 2014, the Financial Accounting Standards Board ("FASB") issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) and has since issued amendments thereto (collectively referred to herein as "ASC 606"). In January 1, 2018, we adopted ASC 606 using the modified retrospective method applied to those contracts which were not completed as of the adoption date. Results for reporting periods beginning after December 31, 2017 are presented under ASC 606, while prior period amounts are not adjusted and continue to be reported under the accounting standards in effect for those periods. Our revenue recognition accounting policies applied prior to adoption of ASC 606 are outlined in the consolidated financial statements in our Annual Report on Form 10-K for the year ended December 31, 2017. The disclosures included herein reflect our accounting policies under ASC 606.

Diversified Industrial revenues related to product sales are recognized when control of the promised goods is transferred to the customer, in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods. This condition is usually met at a point-in-time when the product has been shipped to the customer, or in certain circumstances when the product has been delivered to the customer, depending on the terms of the contract. However, revenues for certain custom manufactured goods are recognized over time as the customer order is fulfilled (for example, contracts for sale of custom manufactured goods that do not have an alternative use and for which the Company has an enforceable right to payment). Certain customers may receive sales incentives, such as right of return, rebates, volume discounts and early payment discounts, which are accounted for as variable consideration. The Company estimates these amounts based on the expected incentive amount to be provided to customers and reduces revenues. Revenue is reported net of any sales or usage-based tax collected. Cash received from customers prior to shipment of goods, or otherwise not yet earned, is recorded as deferred revenue. Service revenues are generated primarily by the Energy segment's energy and sports businesses and by the repair and maintenance work performed on equipment used at mass merchants, supermarkets and restaurants in the Diversified Industrial segment. Service revenues are primarily recognized in the amount to which the entity has a right to invoice. The Company records all shipping and handling fees billed to customers as revenue. If revenue is recognized for the related good before the shipping and handling activities occur, the related costs of those shipping and handling activities are accrued.

The Company has also entered into rebate agreements with certain customers. These programs are typically structured to incentivize the customers to increase their annual purchases from the Company. The rebates are usually calculated as a percentage of the purchase amount, and such percentages may increase as the customer's level of purchases rise. Rebates are recorded as a reduction of net sales in the Company's consolidated statements of operations. As of December 31, 2018 and 2017, accrued rebates payable totaled $12,345 and $8,300, respectively, and are included in Accrued liabilities on the Company's consolidated balance sheets.

Financial Services Segment

WebBank generates revenue through a combination of interest income and non-interest income. Interest income is derived from interest and fees earned on loans and investments. Interest income is accrued on the unpaid principal balance, including amortization of premiums and accretion of discounts. Loan origination fees, net of certain direct origination costs, are deferred and recognized as an adjustment of the related loan yield over the estimated life of the loan. Non-interest income is primarily derived from premiums on the sale of loans, loan servicing fees, origination fees earned on loans and fee income on contractual lending arrangements.

Concentration of Revenue

Concentration of Revenue

No single customer accounted for 5% or more of the Company's consolidated revenues in 2018 or 2017.

Fair Value Measurements

Fair Value Measurements

The Company measures certain assets and liabilities at fair value (see Note 18 - "Fair Value Measurements"). Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair values of assets and liabilities are determined based on a three-level measurement input hierarchy. Level 1 inputs are quoted prices in active markets for identical assets or liabilities as of the measurement date. Level 2 inputs are other than quoted market prices that are observable, either directly or indirectly, for an asset or liability. Level 2 inputs can include quoted prices in active markets for similar assets or liabilities, quoted prices in a market that is not active for identical assets or liabilities, or other inputs that can be corroborated by observable market data. Level 3 inputs are unobservable for the asset or liability when there is little, if any, market activity for the asset or liability. Level 3 inputs are based on the best information available, and may include data developed by the Company.

Stock-Based Compensation

-Based Compensation

The Company accounts for restricted stock units granted to employees and non-employee directors as compensation expense, which is recognized in exchange for the services received. The compensation expense is based on the fair value of the equity instruments on the grant-date and is recognized as an expense over the service period of the recipients.

Income Taxes

Income Taxes

SPLP and certain of its subsidiaries, as limited partnerships, are generally not responsible for federal and state income taxes, and their profits and losses are passed directly to their partners for inclusion in their respective income tax returns. SPLP's subsidiaries that are corporate entities are subject to federal and state income taxes and file corporate income tax returns.

SPLP's subsidiaries that are subject to income taxes use the liability method of accounting for such taxes. Under the liability method, deferred tax assets and deferred tax liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases, and operating loss and tax credit carryforwards. Deferred tax assets and deferred tax liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and deferred tax liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. Such subsidiaries evaluate the recoverability of deferred tax assets and establish a valuation allowance when it is more likely than not that some portion of the deferred tax assets will not be realized.

When tax returns are filed, it is highly certain that most positions taken would be sustained upon examination by the taxing authorities, while others are subject to uncertainty about the merits of the position taken or the amount of the position that would be ultimately sustained. The benefit of a tax position is recognized in the Company's consolidated financial statements in the period during which, based on all available evidence, management believes it is more likely than not that the position will be sustained upon examination, including the resolution of appeals or litigation processes, if any. Tax positions taken are not offset or aggregated with other positions. Tax positions that meet the more-likely-than-not recognition threshold are measured as the largest amount of tax benefit that is more than 50% likely of being realized upon settlement with the applicable taxing authority. The portion of the benefits associated with tax positions taken that exceeds the amount measured as described above is provided for and reflected as a liability for unrecognized tax benefits on the Company's consolidated balance sheets, along with any associated interest and penalties that would be payable to the taxing authorities upon examination.

SPLP's policy is to record estimated interest and penalties related to the underpayment of income taxes as income tax expense in its consolidated statements of operations.

The Company does not release income tax effects from AOCI until the underlying asset or liability to which the income tax relates has been derecognized from the balance sheet or otherwise terminated.

Foreign Currency Translation

Foreign Currency Translation

Assets and liabilities of SPLP's foreign subsidiaries are translated at current exchange rates and related revenues and expenses are translated at average rates of exchange in effect during the year. Resulting cumulative translation adjustments are recorded as a separate component of other comprehensive income or loss. Gains and losses arising from transactions denominated in a currency other than the functional currency of the reporting entity are included in earnings.

Legal Contingencies

Legal Contingencies

The Company provides for legal contingencies when the liability is probable and the amount of the associated loss is reasonably estimable. The Company regularly monitors the progress of legal contingencies and revises the amounts recorded in the period in which a change in estimate occurs.

Environmental Liabilities

Environmental Liabilities

The Company accrues for losses associated with environmental remediation obligations when such losses are probable and reasonably estimable. Accruals for estimated losses from environmental remediation obligations generally are recognized no later than completion of the remedial feasibility study.

Such accruals are adjusted as further information develops or circumstances change. Costs of future expenditures for environmental remediation obligations are not discounted to their present value. Recoveries of environmental remediation costs from other parties are recorded as assets when their receipt is deemed probable.

New or Recently Adopted Accounting Standards

New or Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASC 606 relating to revenue recognition. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services, and the guidance defines a five-step process to achieve this core principle. ASC 606 also requires additional disclosure about the nature, amount, timing and uncertainty of revenues and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The Company adopted ASC 606 as of January 1, 2018 using the modified retrospective transition method. For additional information, see Note 3 - "Revenues."

In January 2016, the FASB issued ASU 2016-01, Financial Instruments—Overall (Subtopic 825-10), which eliminates the requirement to classify equity securities with readily determinable market values as either available-for-sale or trading securities, and requires that equity investments, other than those accounted for under the traditional equity method of accounting, be measured at their fair value with changes in fair value recognized in net income or loss. In the past, changes in fair value were reported in the Company's consolidated statement of comprehensive (loss) income and in AOCI. Equity investments that do not have readily determinable market values may be measured at cost under ASU 2016-01, subject to an assessment for impairment. We adopted ASU 2016-01 effective January 1, 2018. Upon adoption, we recorded a cumulative effect reclassification adjustment from AOCI to Partners' capital of $91,078, which represented the accumulated net unrealized gain on equity securities that was held in AOCI as of December 31, 2017. See also Note 15 - "Capital and Accumulated Other Comprehensive Loss." Furthermore, to have a comparable presentation in our prior-period financial statements after adoption of ASU 2016-01 in 2018, we reclassified realized gains of $790 for the year ended December 31, 2017 from Other (income) expense, net to Realized and unrealized losses (gains) on securities, net in both the consolidated statement of operations and consolidated statement of cash flows for 2017.

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which is effective for public companies for annual reporting periods beginning after December 15, 2018, including interim periods within those fiscal years. The new standard establishes a right-of-use ("ROU") model that requires a lessee to record a ROU asset and a lease liability, measured on a discounted basis, on the balance sheet for all leases with terms longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of expense recognition in the statement of operations. In July 2018, the FASB issued ASU 2018-10, Codification Improvements to Topic 842, Leases, which clarified various aspects of the guidance under ASU 2016-02. Originally, entities were required to adopt ASU 2016-02 using a modified retrospective approach, which required prior periods to be presented under this new standard with certain practical expedients available. However, in July 2018, the FASB issued ASU 2018-11, Leases (Topic 842): Targeted Improvements, which now allows entities the option of recognizing the cumulative effect of applying the new standard as an adjustment to the opening balance of retained earnings in the year of adoption (January 1, 2019) while continuing to present all prior periods under previous lease accounting guidance. ASU 2016-02 and its various amendments and clarifications are collectively referred to herein as "ASC 842."

The Company will adopt ASC 842 in the first quarter of 2019 using the alternative modified transition method. Under this method, the cumulative-effect adjustment to the opening balance of retained earnings is recognized on the date of adoption with prior periods not restated. The Company will also elect to use the package of practical expedients permitted under the transition guidance, such as, carryforward of our historical lease classification, no reassessment on whether an expired or existing contract contains an embedded lease, no reassessment of initial direct costs for any leases that exist prior to adoption of the new standard and to consolidate lease and non-lease components. We are also electing to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of operations on a straight-line basis over the lease term.

The Company has completed its implementation plan for the new lease standard, which includes an information system, and business process and control changes, to accumulate the appropriate data in order to calculate and record the recognition of ROU assets, lease liabilities and the related expense recognition. We estimate that based on our portfolio of leases as of December 31, 2018, approximately $51,000 of ROU lease assets and $53,000 of lease liabilities will be recognized on our consolidated balance sheet upon adoption, primarily relating to building rentals.

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The new standard changes the impairment model for most financial assets that are measured at amortized cost and certain other instruments, including trade receivables, from an incurred loss model to an expected loss model and adds certain new required disclosures. Under the expected loss model, entities will recognize estimated credit losses to be incurred over the entire contractual term of the instrument rather than delaying recognition of credit losses until it is probable the loss has been incurred. The new standard is effective for the Company's 2020 fiscal year with early adoption permitted for all entities in fiscal years beginning after December 15, 2018. The Company is currently evaluating the potential impact of this new guidance; however, it expects that it could have a significant impact on the Company's ALLL.

In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. This new standard provides guidance to help decrease diversity in practice in how certain cash receipts and cash payments are classified in the statement of cash flows. The amendments in ASU 2016-15 provide guidance on eight specific cash flow issues. We adopted ASU 2016-15 effective January 1, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In November 2016, the FASB issued ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash. This new standard provides guidance on the classification of restricted cash in the statement of cash flows. We adopted ASU 2016-18 effective January 1, 2018. As a result of the adoption of ASU 2016-18, in the consolidated statement of cash flows for the year ended December 31, 2017, we reclassified $15,629 of restricted cash.

In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business. This new standard provides guidance to help determine more clearly what is a business acquisition, as opposed to an asset acquisition.The amendments provide a screen to help determine when a set of components is a business by reducing the number of transactions in an acquisition that need to be evaluated. The new standard states that to classify the acquisition of assets as a business, there must be an input and a substantive process that jointly contribute to the ability to create outputs, with outputs being defined as the key elements of the business. If all of the fair value of the assets acquired are concentrated in a single asset group, this would not qualify as a business. The Company adopted ASU 2017-01 effective January 1, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In January 2017, the FASB issued ASU 2017-04, Intangibles-Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment. This new standard simplifies subsequent measurements of goodwill by eliminating Step 2 from the goodwill impairment test. Instead, entities will perform their interim or annual goodwill impairment testing by comparing the fair value of a reporting unit with its carrying amount and recognizing an impairment charge based on the amount that the carrying amount exceeds the reporting unit's fair value. The loss recognized should not exceed the total goodwill allocated to the reporting unit. The amendments in ASU 2017-04 are effective for the Company's 2020 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In March 2017, the FASB issued ASU 2017-07, Compensation-Retirement Benefits (Topic 715): Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. This new standard requires the components of net benefit cost to be disaggregated within the statement of operations, with service cost being included in the same line item as other compensation costs, and any other components being presented outside of operating income. The Company adopted ASU 2017-07 effective January 1, 2018. Since the Company's significant pension plans have been frozen, there is no substantial service cost associated with such plans and therefore, the adoption of ASU 2017-07 did not have a material impact on the Company's consolidated financial statements.

In May 2017, the FASB issued ASU 2017-09, Compensation-Stock Compensation (Topic 718): Scope of Modification Accounting. This new standard provides guidance about which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The standard states that entities should account for the effects of a modification unless the fair value of the modified award is the same as the fair value of the original award, the vesting conditions do not change, and the classification as an equity instrument or a liability instrument is the same. We adopted ASU 2017-09 effective January 1, 2018. The adoption of this standard did not have a material impact on the Company's consolidated financial statements.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities. This new standard was created to refine and expand hedge accounting for both financial and commodity risk in order to simplify the current application of hedge accounting guidance in current U.S. GAAP. This new standard creates more transparency around how hedging results are presented, both in the notes and on the face of the financial statements. The amendments in ASU 2017-12 are effective for the Company's 2019 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In February 2018, the FASB issued ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The new standard provides financial statement preparers with an option to reclassify stranded tax effects within AOCI to retained earnings in each period in which the effect of the change in the U.S. federal corporate income tax rate in the federal Tax Cuts and Jobs Act ("Act") is recorded. The amendments in ASU 2018-02 are effective for the Company's 2019 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In March 2018, the FASB issued ASU 2018-05, Amendments to SEC Paragraphs Pursuant to SEC Staff Accounting Bulletin No. 118. ASU 2018-05 applies to income tax effects from the enactment of the Act in December 2017. ASU 2018-05 allows a Company to report as provisional those amounts where the Company does not have the necessary information available, prepared or analyzed in reasonable detail to complete the accounting under Accounting Standards Codification Topic 740. ASU 2018-05 further allows a measurement period, not to exceed one year from the enactment date of Act, during which an entity may need to reflect adjustments to its provisional amounts. ASU 2018-05 requires that any adjustments to provisional amounts during the measurement period be included in income from continuing operations as an adjustment to tax expense or benefit, and also requires certain disclosures. The provisions of ASU 2018-05 were effective as of the enactment date of the Act, December 22, 2017.

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting. This new standard was created to simplify the accounting for share-based payments to nonemployees. This standard provides guidance on how to account for share-based payment transactions with nonemployees in which a grantor acquires goods or services to be used or consumed in the grantor's own operations by issuing share-based payment awards. The amendments in ASU 2018-07 are effective for the Company's 2019 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework-Changes to the Disclosure Requirements for Fair Value Measurement. ASU 2018-13 modifies the disclosure requirements on fair value measurements. The amendments in ASU 2018-13 are effective for the Company's 2020 fiscal year, except that the standard permits an entity to early adopt any removed or modified disclosures upon issuance of ASU No. 2018-13 and delay adoption of the additional disclosures until the effective date. Because ASU 2018-13 affects disclosure only, management does not expect that the full adoption of this standard will have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-14, Compensation-Retirement Benefits-Defined Benefit Plans-General (Subtopic 715-20): Disclosure Framework-Changes to the Disclosure Requirements for Defined Benefit Plans. ASU 2018-14 modifies the disclosure requirements for employers that sponsor defined benefit pension and other post-retirement plans. The amendments in ASU 2018-14 are effective for the Company's 2021 fiscal year. Because ASU 2018-14 affects disclosure only, management does not expect that the adoption of this standard will have a material impact on the Company's consolidated financial statements.

In August 2018, the FASB issued ASU 2018-15, Intangibles-Goodwill and Other-Internal-Use Software (Subtopic 350-40): Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract (a consensus of the FASB Emerging Issues Task Force) to align the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal use software license). The amendments in ASU 2018-15 are effective for the Company's 2020 fiscal year. The Company is currently evaluating the potential impact of this new guidance.

(1) Certain investments that are measured at fair value using the net asset value per share (or its equivalent) practical expedient have not been classified in the fair value hierarchy.

(2) Hedge funds and common trust funds are comprised of shares or units in commingled funds that may not be publicly traded. The underlying assets in these funds are primarily publicly traded equity securities and fixed income securities.

(3) The limited partnership is a direct lending private debt fund, which serves as an alternative source of liquidity for the shipping industry.

(4) The limited partnership's strategy is to build a concentrated portfolio of 8-10 companies with $100 to $1,000 of equity allocated per investment. Investments will be control positions of minority stakes with significant protections and influence. The strategy will focus on the North American and Asian financial, industrial, energy, consumer and business service sectors.

(5) The limited partnership operates as a fund of funds. The underlying assets in this fund are generally expected to be illiquid. The limited partnership's investment strategy is to seek above-average rates of return and long-term capital growth by investing in a broad range of investments, including, but not limited to, global distressed corporate securities, activist equities, value equities, post-reorganizational equities, municipal bonds, high yield bonds, leveraged loans, unsecured debt, collateralized debt obligations, mortgage-backed securities, commercial mortgage-backed securities, direct lending and sovereign debt.

(6) The offshore feeder fund's Pan-Asia strategy employs a value-oriented and concentrated approach with a long-term horizon and seeks to build a portfolio of independent long and short positions with access to small/mid-cap opportunities.

(7) The JPS Pension Plan holds a deposit administration group annuity contract with an immediate participation guarantee from Transamerica Life Insurance Company ("TFLIC"). The TFLIC contract unconditionally guarantees benefits to certain salaried JPS Pension Plan participants earned through June 30, 1984 in the pension plan of a predecessor employer. The assets deposited under the contract are held in a separate custodial account ("TFLIC Assets"). If the TFLIC Assets decrease to the level of the trigger point (as defined in the contract), which represents the guaranteed benefit obligation representing the accumulated plan benefits as of June 30, 1984, TFLIC has the right to cause annuities to be purchased for the individuals covered by these contract agreements. No annuities have been purchased for the individuals covered by these contract arrangements.

API's pension plan's assets at December 31, 2018 and 2017 by asset category, are as follows:
