Organization, Consolidation and Presentation of Financial Statements [Abstract]
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 various companies, including diversified industrial products, energy, defense, supply chain management and logistics, direct marketing, banking and youth sports. SPLP operates through the following segments: Diversified Industrial, Energy and Financial Services, which are managed separately and offer different products and services. For additional details related to the Company's reportable segments, see Note 18 - "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 17 - "Related Party Transactions." Impact of COVID-19 In March 2020, the World Health Organization categorized COVID-19 as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The spread of the outbreak has caused significant disruptions in the U.S. and global economies and the Company is subject to risks and uncertainties as a result of the COVID-19 pandemic. The Company continues to actively monitor the COVID-19 pandemic and its potential impacts on the Company's employees, customers, suppliers and financial results. During the year ended December 31, 2020, as the COVID-19 pandemic progressed, the Company initiated many cost reducing actions to help mitigate the financial impact of the pandemic. The Company continues to evaluate further or continued actions as circumstances warrant. The COVID-19 pandemic has adversely affected our consolidated financial results for the first three months of 2021. As the situation surrounding the COVID-19 pandemic remains fluid, it is expected to continue having a negative impact to the Company; however, it is difficult to predict the duration of the pandemic and its continued impact on the Company's business, operations, financial condition and cash flows. There is no certainty that federal, state or local regulations regarding safety measures to address the spread of COVID-19 will not adversely impact the Company's operations. While the Company developed and implemented, and continues to develop and implement, health and safety protocols, business continuity plans and crisis management protocols in an effort to try to mitigate the negative impact of the COVID-19 pandemic to its employees and business, the severity of its impact on the Company's business in the remainder of calendar 2021 and beyond will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic, governmental actions that have been taken, or may be taken in the future, in response to the pandemic, and the extent and severity of the impact on the Company's customers and suppliers, all of which are uncertain and cannot be predicted. The Company's future results of operations and liquidity could be adversely impacted by delays in payments of outstanding receivable amounts beyond normal payment terms, supply chain disruptions and uncertain demand, and the impact of any initiatives or programs that the Company may undertake to address financial and operations challenges faced by its customers. As of the date of issuance of these consolidated financial statements, the extent to which the COVID-19 pandemic may materially impact the Company's financial condition, liquidity or results of operations is uncertain. Basis of Presentation The accompanying unaudited consolidated financial statements as of March 31, 2021 and for the three-month periods ended March 31, 2021 and 2020, which have been prepared by the Company in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") for interim periods, include the accounts of the Company and its consolidated subsidiaries. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation have been reflected herein. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the operating results for the full year. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements on Form 10-K for the year ended December 31, 2020, from which the consolidated balance sheet as of December 31, 2020 has been derived. The Company’s fiscal quarter ends on the last day of the calendar quarter; however, for certain subsidiaries of the Company, the fiscal quarter periods end on the Saturday that is closest to the last day of the calendar quarter, except for the last quarterly period of the fiscal year. The Company and all its subsidiaries close their books for fiscal years on December 31. For ease of presentation, the quarterly financial statements included herein are described as ending on the last day of the calendar quarter. Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"), but is not required for interim reporting purposes, has been condensed or omitted. Management must make estimates and assumptions that affect the consolidated financial statements and the related footnote disclosures. While management uses its best judgment, actual results may differ from those estimates. Certain reclassifications have been made to the prior period financial statements and notes to conform to the current period presentation. Restatement For Correction of Immaterial Errors in Previously Issued Consolidated Financial Statements As previously disclosed in the Company’s Form 10-K for the year ended December 31, 2020, during the fourth quarter of 2020, in connection with the preparation of the consolidated financial statements for the year ended December 31, 2020, the Company identified errors in its previously filed annual consolidated financial statements and unaudited quarterly consolidated financial statements. The errors were not material to any individual prior quarterly or annual period. The prior period errors are related primarily to a division of the Company's Electrical Products business within the Diversified Industrial segment ("Electrical Products Misstatements") and were primarily the result of: (1) divisional management override of internal controls, (2) improper segregation of duties, including failure to obtain independent review of recorded accounting entries and accounting analyses and (3) inadequate documentation and support for and/or untimely preparation of account reconciliations. The Electrical Products Misstatements resulted in: (1) improper valuation of inventories and trade receivables, including the related allowance for doubtful accounts; (2) improper recognition of revenue on contracts performed over time; (3) accounts payable and associated expenses not recorded accurately or in the appropriate period; and (4) other errors. The Company assessed the materiality of the errors in its historical annual consolidated financial statements in accordance with SEC Staff Accounting Bulletin ("SAB") Topic 1.M, Materiality , codified in Accounting Standards Codification ("ASC") 250, Accounting Changes and Error Corrections , and concluded that the errors were not material to the previously filed annual consolidated financial statements or corresponding unaudited interim periods but would be material in the aggregate if corrected solely in the consolidated financial statements as of and for the year ended December 31, 2020. In accordance with ASC 250 (SAB Topic 1.N, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements) , the Company corrected for these errors by revising previously filed 2019 annual consolidated financial statements, including the impact to beginning Partners' capital, in connection with the filing of its 2020 Annual Report on Form 10-K. The revised annual consolidated financial statements also included adjustments to correct certain other immaterial errors, including errors that had previously been adjusted for and disclosed as out of period corrections in the period identified. Additionally, in connection with the filing of this Quarterly Report on Form 10-Q, the Company has disclosed the impact of the restatement to the consolidated interim financial statements as of and for the three months ended March 31, 2020 to correct for the errors. The accompanying footnotes have also been corrected to reflect the impact of the revisions of the previously filed 2020 interim consolidated financial statements. Refer to Note 21 - "Restatement of Previously Issued Consolidated Financial Statements" for reconciliations between as reported and as revised quarterly amounts. Discontinued Operations On January 31, 2020, the Company announced that API Group Limited and certain of its affiliates commenced administration proceedings in the United Kingdom. The purpose of the administration proceedings was to facilitate an orderly sale or wind-down of its United Kingdom operations, which include API Laminates Limited and API Foils Holdings Limited. In the United States, API Americas Inc. voluntarily filed for Chapter 11 proceedings in Bankruptcy Court on February 2, 2020, in order to facilitate the sale or liquidation of its U.S. assets. The API Americas Inc. Chapter 11 bankruptcy proceedings were closed by the Bankruptcy Court on December 21, 2020. The API entities (collectively, "API") were wholly-owned subsidiaries of the Company and were included in the Diversified Industrial segment. The Company deconsolidated API on January 31, 2020 as it no longer held a controlling financial interest as of that date. All references made to financial data in this Quarterly Report on Form 10-Q are to the Company's continuing operations, unless specifically noted. See Note 3 - "Discontinued Operations" for additional information. Adoption of New Accounting Standards In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 removes specific exceptions to the general principles in Topic 740 in order to reduce the complexity of its application. ASU 2019-12 also improves consistency and simplifies existing guidance by clarifying and amending certain specific areas of Topic 740. The Company adopted ASU 2019-12 on January 1, 2021 and the adoption of this standard did not have a material impact on the Company’s consolidated financial statements. In January 2020, the FASB issued ASU 2020-01, Investments-Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. ASU 2020-01 clarifies the interaction between accounting standards related to equity securities, equity method investments and certain derivatives, and is expected to reduce diversity in practice and increase comparability of the accounting for these interactions. The Company adopted ASU 2020-01 on January 1, 2021, and the adoption of this standard did not have a material impact on the Company's consolidated financial statements. Accounting Standards Not Yet Effective In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This 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 over the entire contractual term of the instrument rather than delaying recognition of credit losses until it is probable the loss has been incurred. In May 2019, the FASB issued ASU 2019-05, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief. ASU 2019-05 provides entities with an option to irrevocably elect the fair value option, applied on an instrument-by-instrument basis for eligible instruments, that are within the scope of Subtopic 326-20, upon the adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. The new standards were to be effective for the Company's 2020 fiscal year. In November 2019, the FASB issued ASU 2019-10, Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates . This new standard amended the effective date of Topic 326 for smaller reporting companies until January 1, 2023. A company's determination about whether it is eligible to be a smaller reporting company is based on its most recent determination as of November 15, 2019, in accordance with SEC regulations. As of this date, the Company met the SEC definition of a smaller reporting company. Therefore, the Company will not be required to adopt Topic 326 until January 1, 2023. 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 allowance for loan losses ("ALLL"). 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 end. 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 March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASU 2020-04 is intended to provide temporary optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate, known as LIBOR, or by another reference rate expected to be discontinued. This guidance is effective beginning on March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the impact this guidance may have on its consolidated financial statements and related disclosures.

Revenue from Contract with Customer [Abstract]
Revenues	REVENUES 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 18 - "Segment Information." The following table presents the Company's revenues disaggregated by geography for the three months ended March 31, 2021 and 2020. 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. Three Months Ended 2021 2020 United States $ 295,868 $ 327,599 Foreign 18,625 19,611 Total revenue $ 314,493 $ 347,210 Contract Balances Differences in the timing of revenue recognition, billings and cash collections result in billed trade receivables, unbilled receivables (contract assets) and deferred revenue (contract liabilities) on the consolidated balance sheets. 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 sheets. As of March 31, 2021 and December 31, 2020, the contract asset balance was $10,203 and $17,119, respectively. Contract Liabilities The Company records deferred revenues when cash payments are received or due in advance of the Company's performance, including amounts that are refundable, which are recorded as contract liabilities. Contract liabilities are classified as Other current liabilities on the consolidated balance sheets, based on the timing of when the Company expects to recognize revenue. Contract Liabilities Balance at December 31, 2020 $ 7,707 Deferral of revenue 6,044 Recognition of unearned revenue (5,649) Balance at March 31, 2021 $ 8,102 Balance at December 31, 2019 $ 6,820 Deferral of revenue 4,030 Recognition of unearned revenue (147) Balance at March 31, 2020 $ 10,703

Discontinued Operations	DISCONTINUED OPERATIONS On January 31, 2020, the Company announced that API Group Limited and certain of its affiliates commenced administration proceedings in the U.K. The purpose of the administration proceedings is to facilitate an orderly sale or wind-down of its U.K. operations, which include API Laminates Limited and API Foils Holdings Limited. In the U.S., API Americas Inc. voluntarily filed for Chapter 11 proceedings in Bankruptcy Court on February 2, 2020, in order to facilitate the sale or liquidation of its U.S. assets. The API Americas Inc. Chapter 11 bankruptcy proceedings were closed by the Bankruptcy Court on December 21, 2020. The API entities were wholly-owned subsidiaries of the Company and part of the Diversified Industrial segment. The Company deconsolidated API on January 31, 2020 as it no longer held a controlling financial interest as of that date. On the date of the deconsolidation, the Company believed that API became a variable interest entity. The Company determined at deconsolidation that it was not the primary beneficiary of API as the Company no longer held a controlling financial interest in API and the Company lacked significant decision-making ability. The components of Net loss from discontinued operations, net of taxes in the accompanying consolidated statements of operations are: Three Months Ended March 31, 2020 Loss from operations of discontinued operation $ (2,301) Gain upon initial deconsolidation of API 30,515 Loss from guarantee liability (52,483) Net loss from discontinued operations, net of taxes $ (24,269) All amounts associated with API have been removed from the Company's financial statements and footnotes, and reported in discontinued operations as described herein.

The fair value of loans receivable, including loans held for sale, was $2,886,872 and $2,498,218 as of March 31, 2021 and December 31, 2020, respectively. Loans with a carrying value of approximately $56,818 and $15,849 were pledged as collateral for potential borrowings as of March 31, 2021 and December 31, 2020, respectively. WebBank serviced $2,814 and $2,828 in loans for others as of March 31, 2021 and December 31, 2020, respectively. WebBank sold loans classified as loans held for sale of $2,208,754 and $5,124,275 during the three months ended March 31, 2021 and 2020, respectively. The sold loans were derecognized from the consolidated balance sheets. Loans classified as loans held for sale primarily consist of consumer and small business loans. Amounts added to loans held for sale during the same periods were $2,213,886 and $4,969,689, respectively. The reduction in loans held for sale as of March 31, 2021 reflects the impact of reduced lending by WebBank's partners due to the economic impact of the COVID-19 pandemic. Such factors include lower sales volumes at WebBank's partners as well as tightening their credit policies due to the increase in the U.S. unemployment rates and other factors. This in turn has reduced the volume of loans being initiated by, and then sold by, WebBank. 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 when 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 the level of the ALLL reflect 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. WebBank's ALLL decreased $7,075, or 26%, during the three months ended March 31, 2021. This decrease was driven by lower than expected losses related to COVID-19 and higher paydowns, and, as a result, WebBank released a portion of the allowance for COVID-19 related qualitative and environmental factors. WebBank continues to monitor the impact of the COVID-19 pandemic on its loan portfolio and anticipates potential future economic disruption associated with the pandemic. WebBank believes there remains a potential for broad negative impact on the macro-economy that may cause estimated credit losses to materially differ from historical loss experience. Changes in the ALLL are summarized as follows: Commercial Real Estate Loans Commercial & Industrial Consumer Loans Total December 31, 2020 $ 22 $ 9,293 $ 17,744 $ 27,059 Charge-offs — (3,607) (3,669) (7,276) Recoveries 6 514 396 916 (Benefit) Provision (6) 1,038 (1,747) (715) March 31, 2021 $ 22 $ 7,238 $ 12,724 $ 19,984 Commercial Real Estate Loans Commercial & Industrial Consumer Loans Total December 31, 2019 $ 24 $ 10,920 $ 25,738 $ 36,682 Charge-offs — (3,898) (7,301) (11,199) Recoveries 1 149 653 803 (Benefit) Provision (2) 11,945 14,194 26,137 March 31, 2020 $ 23 $ 19,116 $ 33,284 $ 52,423 The ALLL and outstanding loan balances according to the Company's impairment method are summarized as follows: March 31, 2021 Commercial Real Estate Loans Commercial & Industrial Consumer Loans Total Allowance for loan losses: Individually evaluated for impairment $ 10 $ 92 $ — $ 102 Collectively evaluated for impairment 12 7,146 12,724 19,882 Total $ 22 $ 7,238 $ 12,724 $ 19,984 Outstanding loan balances: Individually evaluated for impairment $ 10 $ 1,202 $ — $ 1,212 Collectively evaluated for impairment 717 2,689,201 127,635 2,817,553 Total $ 727 $ 2,690,403 $ 127,635 $ 2,818,765 December 31, 2020 Commercial Real Estate Loans Commercial & Industrial Consumer Loans Total Allowance for loan losses: Individually evaluated for impairment $ 10 $ 129 $ — $ 139 Collectively evaluated for impairment 12 9,164 17,744 26,920 Total $ 22 $ 9,293 $ 17,744 $ 27,059 Outstanding loan balances: Individually evaluated for impairment $ 10 $ 1,283 $ — $ 1,293 Collectively evaluated for impairment 662 2,278,389 147,652 2,426,703 Total $ 672 $ 2,279,672 $ 147,652 $ 2,427,996 Nonaccrual and Past Due Loans Commercial and industrial loans past due 90 days or more and still accruing interest were $3,797 and $7,369 at March 31, 2021 and December 31, 2020, respectively. Consumer loans past due 90 days or more and still accruing interest were $1,001 and $1,332 at March 31, 2021 and December 31, 2020, respectively. The Company did not have any nonaccrual loans at March 31, 2021 or December 31, 2020. Past due loans (accruing and nonaccruing) are summarized as follows: March 31, 2021 Current 30-89 Days 90+ Days Total Total Loans Recorded Nonaccrual Loans That Are Current (a) Commercial real estate loans $ 727 $ — $ — $ — $ 727 $ — $ — Commercial and industrial 2,680,481 6,125 3,797 9,922 2,690,403 3,797 — Consumer loans 124,162 2,472 1,001 3,473 127,635 1,001 — Total loans $ 2,805,370 $ 8,597 $ 4,798 $ 13,395 $ 2,818,765 $ 4,798 $ — December 31, 2020 Current 30-89 Days 90+ Days Total Total Loans Recorded Nonaccrual Loans That Are Current (a) Commercial real estate loans $ 672 $ — $ — $ — $ 672 $ — $ — Commercial and industrial 2,265,150 7,153 7,369 14,522 2,279,672 7,369 — Consumer loans 142,418 3,902 1,332 5,234 147,652 1,332 — Total loans $ 2,408,240 $ 11,055 $ 8,701 $ 19,756 $ 2,427,996 $ 8,701 $ — (a) Represents nonaccrual loans that are not past due more than 30 days; however, full payment of principal and interest is still not expected. 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 commercial 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 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: March 31, 2021 Non - Graded Pass Special Sub- Doubtful Total Loans Commercial real estate loans $ — $ 717 $ — $ 10 $ — $ 727 Commercial and industrial 194,690 2,489,444 5,067 1,202 — 2,690,403 Consumer loans 127,635 — — — — 127,635 Total loans $ 322,325 $ 2,490,161 $ 5,067 $ 1,212 $ — $ 2,818,765 December 31, 2020 Non - Graded Pass Special Sub- Doubtful Total Loans Commercial real estate loans $ — $ 662 $ — $ 10 $ — $ 672 Commercial and industrial 194,338 2,080,623 3,428 1,283 — 2,279,672 Consumer loans 147,652 — — — — 147,652 Total loans $ 341,990 $ 2,081,285 $ 3,428 $ 1,293 $ — $ 2,427,996 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 in accordance with 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. 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, in accordance with the contractual loan agreement. WebBank recognized $17 and $34 on impaired loans for the three months ended March 31, 2021 and 2020, respectively. Payments received on impaired loans that are nonaccruing are not recognized in interest income, but are applied as a reduction of the principal outstanding. Payments are recognized when cash is received. Information on impaired loans is summarized as follows: Recorded Investment March 31, 2021 Unpaid Principal With No With Total Recorded Related Average Recorded Commercial real estate loans $ 10 $ — $ 10 $ 10 $ 10 $ 10 Commercial and industrial 1,202 — 1,202 1,202 92 1,099 Total loans $ 1,212 $ — $ 1,212 $ 1,212 $ 102 $ 1,109 Recorded Investment December 31, 2020 Unpaid Principal With No With Total Recorded Related Average Recorded Commercial real estate loans $ 10 $ — $ 10 $ 10 $ 10 $ 11 Commercial and industrial 1,283 — 1,283 1,283 129 2,319 Total loans $ 1,293 $ — $ 1,293 $ 1,293 $ 139 $ 2,330 During the three months ended March 31, 2021, WebBank continued issuing loans under the Small Business Administration's ("SBA") Paycheck Protection Program ("PPP"), primarily with one of its lending partners, authorized under the Coronavirus Aid, Relief, and Economic Security ("CARES") Act. The loans were funded by the PPP Liquidity Facility, have terms of between two and five years, and their repayment is guaranteed by the SBA. Payments by borrowers on the loans can begin up to 16 months after the note date, and interest will continue to accrue during the 16-month deferment at 1%. Loans can be forgiven in whole or in part (up to full principal and any accrued interest) if certain criteria are met. Loan processing fees paid to WebBank from the SBA are accounted for as loan origination fees. Net deferred fees are recognized over the life of the loan as yield adjustments on the loans. If a loan is paid off or forgiven by the SBA prior to its maturity date, the remaining unamortized deferred fees will be recognized in interest income at that time. The PPP loans are included in Commercial and industrial loans in the table above. As of March 31, 2021, the total PPP loans and associated liabilities were $2,458,440 and $2,462,193, respectively, and included in Long-term loans receivable, net, and Other borrowings, respectively, in the consolidated balance sheet as of March 31, 2021. As of December 31, 2020, the total PPP loans and associated liabilities were $2,047,769 and $2,090,223, respectively, and included in Long-term loans receivable, net, and Other borrowings, respectively, in the consolidated balance sheet as of December 31, 2020. Upon borrower forgiveness, the SBA pays WebBank for the principal and accrued interest owed on the loan. The timing of loan forgiveness is uncertain at this time, but borrower forgiveness applications and SBA processing is expected over the next several quarters. As the PPP continues to evolve, changes to the loan terms and exercise of loan forgiveness may materially impact the outstanding loan balances and the effective yield. The Company is offering loan modifications to assist borrowers during the COVID-19 pandemic. The CARES Act along with the interagency statement issued by the federal banking agencies provides that loan modifications made in response to COVID-19 do not need to be accounted for as a troubled debt restructuring ("TDR"). Accordingly, the Company does not account for such loan modifications as TDRs. The Company's loan modifications allow for payment deferrals, payment reduction, and settlements amongst others. As of March 31, 2021, the Company had granted loan modifications on $12,206 of

Year Ending December 31, 2021 2022 2023 2024 2025 Estimated amortization expense $ 20,106 $ 17,887 $ 16,891 $ 16,317 $ 14,902 As of March 31, 2021, the Company reviewed its goodwill, other intangible assets and long-lived assets for indicators of impairment as a result of the impact of the COVID-19 pandemic. The Company reviewed its previous forecasts and assumptions based on its current projections, which are subject to various risks and uncertainties, including forecasted revenues, expenses and cash flows, the duration and extent of the impact to our businesses from the COVID-19 pandemic and the Company's market capitalization. In connection with the Company's 2020 annual fourth quarter goodwill impairment testing and as a result of declines in customer demand in the Performance Materials reporting unit, which is included in the Diversified Industrial segment, the Company determined its fair value was less than its carrying value. The Company partially impaired the Performance Materials reporting units' goodwill and recorded a $1,100 charge in Goodwill impairment charges in the consolidated statement of operations for the year ended December 31, 2020. While the Company did not identify further indicators of impairment for Performance Materials as of March 31, 2021, it may be at risk of further impairment in the future if the business does not perform as expected, including if it does not recover as planned from the COVID-19 pandemic, or if market factors utilized in the impairment test deteriorate, including an unfavorable change in the terminal growth rate or the weighted-average cost of capital. As of March 31, 2021, the Performance Materials' reporting unit had $6,808 of goodwill. As of March 31, 2021, the Company believes there were indicators of impairment for the Electrical Products reporting unit due to downward revisions to financial projections as a result of changes in anticipated customer demand as well incremental costs to enhance the business' control environment. As a result, the Company performed an interim impairment test of Electrical Products’ goodwill and other long-lived assets as of March 31, 2021 and the Company determined goodwill and other long-lived assets were not impaired. The fair value of the Electrical Products reporting unit was 6% higher than its carrying value as of March 31, 2021. The fair value was calculated using a discounted cash flow model (a form of the income approach) using the Company's current projections, which are subject to various risks and uncertainties associated with its forecasted revenue, expenses and cash flows, as well as the duration and expected impact on its business from the COVID-19 pandemic. The Company's significant assumptions in the analysis include, but are not limited to, future cash flow projections, the weighted average cost of capital, the terminal growth rate and the tax rate. The Company's estimates of future cash flows are based on current economic climates, recent operating results and planned business strategies. These estimates could be negatively affected by changes in regulations, further economic downturns, decreased customer demand for Electrical Products' services, or an inability to execute management’s business strategies. Future cash flow estimates are, by their nature, subjective, and actual results may differ materially from the Company's estimates. If the Company's ongoing cash flow projections are not met, the Company may have to record impairment charges in future periods. As of March 31, 2021, the Electrical Products' reporting unit had goodwill of $46,445.

Investments, Debt and Equity Securities [Abstract]
Investments	INVESTMENTS Short-Term Investments 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 investments are carried at fair value and totaled $126 and $106 as of March 31, 2021 and December 31, 2020, respectively. Unrealized gains (losses) on short-term investments for the three months ended March 31, 2021 and 2020 were $32 and $(97), respectively. Long-Term Investments The following table summarizes the Company's long-term investments as of March 31, 2021 and December 31, 2020.

("Aerojet"). The Company owned 4.9% and 5.1% of Aerojet common stock as of March 31, 2021 and December 31, 2020, respectively. The fair value of the investment in Aerojet was $185,492 and $208,758 as of March 31, 2021 and December 31, 2020, respectively. Gross unrealized gains for all Corporate securities totaled $174,376 and $126,730 at March 31, 2021 and 2020 . In December 2020, Aerojet's Board of Directors declared a one-time cash dividend of $5.00 per share (the "Pre-Closing Dividend") which was paid on March 24, 2021 to the holders of Aerojet's shares as of the close of business on March 10, 2021.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Financial Instruments	FINANCIAL INSTRUMENTS 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 15 - "Fair Value Measurements"). As of March 31, 2021, outstanding derivatives mature within three Precious Metal and Commodity Inventories As of March 31, 2021, the Company had the following outstanding forward contracts with settlement dates through April 2021. There were no futures contracts outstanding as of March 31, 2021. Commodity Amount Notional Value Silver (ounces) 82,017 $ 1,869 Gold (ounces) 1,355 $ 2,344 Palladium (ounces) 1,183 $ 3,106 Copper (pounds) 390,000 $ 1,615 Tin (metric tons) 18 $ 639 Fair Value Hedges. Certain forward contracts are accounted for as fair value hedges under ASC 815 for the Company's precious metal inventory carried at fair value. These contracts hedge 25,350 ounces of silver and a majority of the Company's ounces of copper. The fair values of these derivatives are recognized as derivative assets and liabilities on the Company's consolidated balance sheets. The net changes in fair value of the derivative assets and liabilities, and the changes 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. Economic Hedges. The remaining outstanding forward contracts for silver, and all the contracts for gold, palladium and tin, are accounted for as 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 with gains and losses recorded in 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. Management evaluated counter party risk and believes 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 are as follows: Fair Value of Derivative Assets (Liabilities) March 31, 2021 December 31, 2020 Balance Sheet Location Fair Value Balance Sheet Location Fair Value Derivatives designated as ASC 815 hedges Commodity contracts Prepaid expenses and other current assets $ 31 Accrued liabilities $ (6) Derivatives not designated as ASC 815 hedges Commodity contracts Accrued liabilities $ (117) Accrued liabilities $ (163) Economic interests in loans Other non-current assets $ 10,542 Other non-current assets $ 11,599 The effects of fair value hedge accounting on the consolidated statements of operations for the three months ended March 31, 2021 and 2020 are not material. The effects of derivatives not designated as ASC 815 hedging instruments on the consolidated statements of operations for the three months ended March 31, 2021 and 2020 are as follows: Derivatives Not Designated as Hedging Instruments: Location of Gain (Loss) Recognized in Income Amount of Gain (Loss) Recognized in Income Three Months Ended 2021 2020 Commodity contracts Other income (expense), net (215) (407) Economic interests in loans Financial services revenue 1,453 2,980 Total $ 1,238 $ 2,573 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 amounts 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. As of March 31, 2021 and December 31, 2020, WebBank's undisbursed loan commitments totaled $115,150 and $170,611, 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.

Common Unit Repurchase Program The Board of Directors of SPH GP has approved the repurchase of up to an aggregate of 5,500,000 of the Company's common units ("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 did not repurchase any common units during the three months ended March 31, 2021. Since inception of the Repurchase Program the Company has purchased 4,357,948 common units for an aggregate price of approximately $54,345. As of March 31, 2021, there remained 1,142,052 units that may yet be purchased under the Repurchase Program. In April 2021, the Company repurchased 661,053 common units for $10,141. On May 12, 2021, the Board of Directors of SPH GP, approved an increase of 1,019,001 common units to the Repurchase Program which increased the remaining units available for purchase to 1,500,000 common units. Incentive Award Plan The Company's 2018 Incentive Award Plan ("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"). On May 18, 2020, the Company's unitholders approved the Amended and Restated 2018 Incentive Award Plan, which increased the number of LP Units issuable under the 2018 Plan by 500,000 to a total of 1,000,000 LP Units. The Company granted 28,000, restricted units on March 10, 2021 under the 2018 Plan. Such units were valued based upon the market value of the Company's LP Units on the date of grant, and collectively represent approximately $374 of unearned compensation that will be recognized as expense ratably over the vesting period of the units. The grants have cliff vesting periods that range from one Preferred Units The Company's 6.0% Series A preferred units, no par value ("SPLP Preferred Units") entitle the holders to a cumulative quarterly cash or in-kind (or a combination thereof) distribution. The Company declared cash distributions of approximately $2,408 and $2,725 to preferred unitholders for the three months ended March 31, 2021 and 2020, respectively. The SPLP Preferred Units have a term of nine years, ending February 2026, 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. 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 non-current liabilities, including accrued interest expense, on the Company's consolidated balance sheets 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 liabilities, distributions thereon are recorded as a component of Interest expense in the Company's consolidated statements of operations. As of March 31, 2021 and December 31, 2020, there were 6,422,128 SPLP Preferred Units outstanding. On May 12, 2021, the Board of Directors of SPH GP declared a regular quarterly cash distribution of $0.375 per unit, payable June 15, 2021, to unitholders of record as of June 1, 2021, on its SPLP Preferred Units.

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. Performance is principally determined by comparing the volume weighted-average price of the Company's common units for 20 days prior to a measurement date with a defined baseline equity value per common unit, currently $19.65 per common unit, and incentive units will only be granted if such annual measurement is positive. 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. No incentive unit expense was recorded in the three months ended March 31, 2021 and 2020.

There were no transfers of securities among the various measurement input levels during the three months ended March 31, 2021. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e. the "exit price") in an orderly transaction between market participants at the measurement date. Fair value measurements are broken down into three levels based on the reliability of inputs as follows: Level 1 inputs are quoted prices in active markets for identical assets or liabilities as of the measurement date ("Level 1"). Level 2 inputs may 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 2"). 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 ("Level 3"). 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 10 - "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 Economic Interests in Loans Warrants Total Balance as of December 31, 2020 $ 48,434 $ 11,599 $ 2,618 $ 62,651 Purchases — — — — Sales and cash collections — (2,510) (536) (3,046) Realized gains — 1,453 2,878 4,331 Unrealized gains 3,062 — — 3,062 Unrealized losses — — — — Balance as of March 31, 2021 $ 51,496 $ 10,542 $ 4,960 $ 66,998 Balance as of December 31, 2019 $ 53,658 $ 18,633 $ 2,086 $ 74,377 Purchases — — — — Sales and cash collections — (4,112) — (4,112) Realized gains — 2,980 — 2,980 Unrealized gains — — — — Unrealized losses (19,277) — — (19,277) Balance as of March 31, 2020 $ 34,381 $ 17,501 $ 2,086 $ 53,968 (a) Unrealized gains and losses are recorded in (Income) loss of associated companies, net of taxes in the Company's consolidated statements of operations. (b) Realized and unrealized gains and losses are recorded in Realized and unrealized (gains) losses on securities, net or Financial services revenue in the Company's consolidated statements of operations. Long-Term Investments - Valuation Techniques The Company estimates the value of its investments in STCN preferred stock and the New Note using a Monte Carlo simulation. Key inputs in these valuations 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, redemption date of the preferred stock and the maturity date of the New Note. Marketable Securities and Other - Valuation Techniques The Company 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 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 10 - "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 flow analyses that consider credit, performance and prepayment. Unobservable inputs used in the discounted cash flow analyses are: a constant prepayment rate of 7.84% to 35.77%, a constant default rate of 1.89% to 17.96% and a discount rate of 2.00% to 26.19%. 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

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES 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 March 31, 2021, on a consolidated basis, the Company has recorded liabilities of $1,729 and $24,138 in Accrued liabilities and Other non-current liabilities, respectively, 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 subsidiaries of HNH 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 findings, techniques and alternative methods. HNH recorded liabilities of approximately $24,491 related to estimated environmental investigation and remediation costs as of March 31, 2021. 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 at some of the sites at which HNH subsidiaries are PRP's. 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 an 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 former HNH manufacturing facility located in Fairfield, Connecticut. An ecological risk assessment of the wetlands portion was submitted in the second quarter of 2016 to the CTDEEP for their review and approval. Company officials met with CTDEEP representatives during the third quarter of 2020 to further discuss wetlands remediation goals and plans. Additional investigation of the wetlands is expected to start in 2021, pending approval of a mutually acceptable wetlands work plan. An updated work plan to investigate the upland portion of the parcel was prepared by the Company and approved by the CTDEEP in March 2018 and completed during 2019 and 2020. Additional upland investigatory work will be required to fully define the areas requiring remediation and is also dependent upon CTDEEP requirements and approval. Based on currently known information, the Company reasonably estimates that it may incur aggregate losses over a period of multiple years of between $10,500 to $17,500. During the second quarter of 2020, the Company increased its reserve for future remediation costs by $14,000, which is our best estimate within this range of potential losses. Due to the uncertainties, there can be no assurance that the final resolution of this matter will not be material to the financial position, results of operations or cash flows of HNH or 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 property in Montvale, New Jersey that it purchased in 1984. 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 additional opportunities to improve the current treatment system. Pursuant to a settlement agreement with the former owner/operator of the site, the responsibility for site investigation and remediation costs and other related 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. Additionally, HHEM had been reimbursed indirectly through insurance coverage for a portion of the costs for which it is responsible. 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 $1,000 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. On December 18, 2019, the State of New Jersey ("State") filed a complaint against HHEM, the Company and other non-affiliated corporations related to former operations at this location. The State is seeking unspecified damages, including reimbursement for all cleanup and removal costs and other damages that the State has incurred, including the lost value of, and reasonable assessment costs for any natural resource injured as a result of the alleged discharge of hazardous substances and pollutants, as well as attorneys' fees and costs. The Company intends to assert all legal and procedural defenses available. Based upon currently available information, the Company has determined that a range of potential loss cannot be reasonably estimated at this time. 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 entered into a consent decree with both the U.S. Department of Justice and the U.S. Environmental Protection Agency ("EPA") and has since completed the remediation required by the consent decree and has paid the 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. 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. The State did not specifically identify its alleged damages in the complaint. SLI intends to assert all legal and procedural defenses available to it. Based upon currently available information, the Company has determined that a range of potential loss can no longer 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 have been completed under the direction of the licensed site remediation professional ("LSRP") for the site. Additional soil excavation and chemical treatment is expected to start in the second quarter of 2021. Post-remediation groundwater monitoring will be conducted, and a full-scale groundwater bioremediation is expected to be implemented following completion of soil excavation. A reserve of $2,600 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 have 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 $1,200 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. Litigation Matters On December 8, 2017, a 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. The action named as defendants the former members of the HNH board of directors, the Company and SPH GP, and alleged, 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 sought, among other relief, unspecified monetary damages, attorneys' fees and costs. On July 9, 2019, the Company entered into a settlement of the case, solely to avoid the substantial burden, expense, inconvenience and distraction of continued litigation and to resolve each of the plaintiff's claims against the defendant parties. In the settlement, the defendants agreed to pay the plaintiff class $30,000, but denied that they engaged in any wrongdoing or committed any violation of law or breach of duty and stated that they believe they acted properly, in good faith, and in a manner consistent with their legal duties. The settlement was approved by the court on December 2, 2019. Our insurance carriers agreed to contribute an aggregate of $17,500 toward the settlement amount. The Company recorded a charge of $12,500 in Selling, general and administrative expenses in the consolidated statement of operations for the twelve months ended December 31, 2019, which consisted of the legal settlement of $30,000, reduced by the $17,500 of insurance recoveries. The settlement was paid on December 17, 2019. The Company made a demand of an aggregate of $10,000 in further contributions from two insurance carriers, which the carriers declined, and it is pursuing claims in court to endeavor to recover this sum, although there can be no assurance as to the outcome of this litigation. On April 13, 2018, a purported shareholder of STCN, Donald Reith, filed a verified complaint, Reith v. Lichtenstein, et al., 2018-0277 (Del. Ch.) in the Delaware Court of Chancery. The plaintiff seeks to assert claims against the Company and certain of its affiliates and against the members of STCN's board of directors in connection with the acquisition of $35,000 of STCN's Series C Preferred Stock by an affiliate of the Company and equity grants made to three individual defendants. The complaint includes claims for breach of fiduciary duty as STCN directors against all the individual defendants; claims for aiding and abetting breach of fiduciary duty against the Company; a claim for breach of fiduciary duty as controlling stockholder against the Company; and a derivative claim for unjust enrichment against the Company and the three individuals who received equity grants. The complaint demands damages in an unspecified amount for STCN and its stockholders, together with rescission, disgorgement and other equitable relief. The defendants moved to dismiss the complaint for failure to plead demand futility and failure to state a claim. On June 28, 2019, the Court of Chancery issued an opinion denying in substantial part the motion. The Company will continue to vigorously defend 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 March 31, 2021. In many cases these claims involved more than 100 defendants. There remained approximately 35 pending asbestos claims as of March 31, 2021. 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 March 31, 2021 and December 31, 2020, 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. OMG was party to litigation with the U.S. Government regarding whether materials purchased by OMG from a foreign supplier are subject to antidumping duty and countervailing duty orders ("ADD/CVD Orders"). The ADD/CVD Orders were issued in 2015 by the U.S. Government, and this matter was subject to ongoing litigation since 2016, at which time OMG paid $949 to the U.S. Government and recorded an additional $4,100 accrual for its then expected resolution of this matter. On August 28, 2020, the U.S. Court of Appeals for the Federal Circuit issued an opinion in favor of OMG on the matter. The U.S. Government did not appeal this decision to the U.S. Supreme Court within the 150 days appeal deadline, which expired on January 25, 2021. As such, OMG is not expected to incur any liability with respect to the ADD/CVD Orders. Therefore, as of December 31, 2020, the $4,100 prior accrual for this matter was reversed and a receivable of $949 was recorded for the expected refund of the amounts previously paid to the U.S. Government. The $5,049 total for both items was recorded as a reduction to cost of goods sold in the consolidated statement of operations for the year ended December 31, 2020. As of March 31, 2021, the $949 receivable was not collected. In the ordinary course of our business, the Company is 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 the Company cannot predict with certainty the ultimate resolution of lawsuits, investigations, claims and proceedings asserted against the Company, it does not believe any currently pending legal proceeding to which it is a party will have a material adverse effect on its 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. As a result of Basel III becoming fully implemented as of January 1, 2019, WebBank's 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 raises 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), and 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 Actual For Capital Minimum Capital Adequacy With To Be Well Capitalized Under Amount Ratio Amount Ratio Amount Ratio Amount Ratio As of March 31, 2021 Total Capital (to risk-weighted assets) $ 222,035 38.50 % $ 46,078 8.00 % $ 60,478 10.50 % $ 57,598 10.00 % Tier 1 Capital (to risk-weighted assets) $ 214,678 37.30 % $ 34,559 6.00 % $ 48,958 8.50 % $ 46,078 8.00 % Common Equity Tier 1 Capital (to risk-weighted assets) $ 214,678 37.30 % $ 25,919 4.50 % $ 40,319 7.00 % $ 37,439 6.50 % Tier 1 Capital (to average assets) $ 214,678 28.90 % $ 29,748 4.00 % n/a n/a $ 37,185 5.00 % As of December 31, 2020 Total Capital (to risk-weighted assets) $ 212,002 34.30 % $ 49,512 8.00 % $ 64,985 10.50 % $ 61,891 10.00 % Tier 1 Capital (to risk-weighted assets) $ 204,028 33.00 % $ 37,134 6.00 % $ 52,607 8.50 % $ 49,512 8.00 % Common Equity Tier 1 Capital (to risk-weighted assets) $ 204,028 33.00 % $ 27,851 4.50 % $ 43,323 7.00 % $ 40,229 6.50 % Tier 1 Capital (to average assets) $ 204,028 32.40 % $ 25,219 4.00 % n/a n/a $ 31,523 5.00 % ` The Federal Reserve, Office of the Comptroller of Currency and Federal Deposit Insurance Corporation issued an interim final rule that excludes loans pledged as collateral to the Federal Reserve's PPP Lending Facility from supplementary leverage ratio exposure and average total consolidated assets. Additionally, PPP loans will receive a zero percent risk weight under the risk-based capital rules of the federal banking agencies.

Accounting Changes and Error Corrections [Abstract]
Restatement of Previously Issued Consolidated Financial Statements	RESTATEMENT OF PREVIOUSLY ISSUED CONSOLIDATED FINANCIAL STATEMENTS As described in Note 1 - " Basis of Presentation,", the following errors in the Company's interim consolidated financial statements as of and for the three months ended March 31, 2020 were identified and corrected as a result of the Electrical Products Misstatements, as well as other immaterial errors: a. Cash and cash equivalents – As a result of the correction of a prior period balance sheet presentation error, apart from the Electrical Products Misstatements, Cash and cash equivalents decreased by $1,519 as of December 31, 2019. b. Revenue – The Company corrected certain errors in the application of its revenue recognition policy under U.S. GAAP, which decreased total Revenue by $690 for the three months ended March 31, 2020. These adjustments are primarily for correction of errors separate from the Electrical Products Misstatements. c. Cost of goods sold – Primarily as a result of the correction of the Electrical Products Misstatements, Cost of goods sold decreased by $231 for the three months ended March 31, 2020. These Electric Products Misstatements were due primarily to irregularities in revenue recognition journal entries, irregularities relating to Accounts payable and improper valuation of inventories. d. Selling, general and administrative expenses – Primarily as a result of error corrections separate from the Electrical Products Misstatements, Selling, general and administrative expenses decreased by $736 for the three months ended March 31, 2020. e. Interest expense – As a result of the net impact of the error corrections, Interest expense for the Company's Credit Agreement increased by $312 for the three months ended March 31, 2020 due to the impact of covenant calculations. f. Income tax provision – As a result of the net impact of the error corrections, Income tax provision increased by $15 for the three months ended March 31, 2020. g. Net loss on deconsolidation of discontinued operations – The Company corrected errors apart from the Electrical Products Misstatements, which decreased Net loss on deconsolidation of discontinued operations by $879 for the three months ended March 31, 2020 due primarily to recognition of an asset impairment charge.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Impact of Covid-19	Impact of COVID-19 In March 2020, the World Health Organization categorized COVID-19 as a pandemic, and the President of the United States declared the COVID-19 outbreak a national emergency. The spread of the outbreak has caused significant disruptions in the U.S. and global economies and the Company is subject to risks and uncertainties as a result of the COVID-19 pandemic. The Company continues to actively monitor the COVID-19 pandemic and its potential impacts on the Company's employees, customers, suppliers and financial results. During the year ended December 31, 2020, as the COVID-19 pandemic progressed, the Company initiated many cost reducing actions to help mitigate the financial impact of the pandemic. The Company continues to evaluate further or continued actions as circumstances warrant. The COVID-19 pandemic has adversely affected our consolidated financial results for the first three months of 2021. As the situation surrounding the COVID-19 pandemic remains fluid, it is expected to continue having a negative impact to the Company; however, it is difficult to predict the duration of the pandemic and its continued impact on the Company's business, operations, financial condition and cash flows. There is no certainty that federal, state or local regulations regarding safety measures to address the spread of COVID-19 will not adversely impact the Company's operations. While the Company developed and implemented, and continues to develop and implement, health and safety protocols, business continuity plans and crisis management protocols in an effort to try to mitigate the negative impact of the COVID-19 pandemic to its employees and business, the severity of its impact on the Company's business in the remainder of calendar 2021 and beyond will depend on a number of factors, including, but not limited to, the duration and severity of the pandemic, governmental actions that have been taken, or may be taken in the future, in response to the pandemic, and the extent and severity of the impact on the Company's customers and suppliers, all of which are uncertain and cannot be predicted. The Company's future results of operations and liquidity could be adversely impacted by delays in payments of outstanding receivable amounts beyond normal payment terms, supply chain disruptions and uncertain demand, and the impact of any initiatives or programs that the Company may undertake to address financial and operations challenges faced by its customers. As of the date of issuance of these consolidated financial statements, the extent to which the COVID-19 pandemic may materially impact the Company's financial condition, liquidity or results of operations is uncertain.
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements as of March 31, 2021 and for the three-month periods ended March 31, 2021 and 2020, which have been prepared by the Company in accordance with the rules and regulations of the Securities and Exchange Commission ("SEC") for interim periods, include the accounts of the Company and its consolidated subsidiaries. In the opinion of management, all adjustments, consisting of normal recurring adjustments, necessary for a fair presentation have been reflected herein. The results of operations for the three months ended March 31, 2021 are not necessarily indicative of the operating results for the full year. The accompanying unaudited consolidated financial statements should be read in conjunction with the Company's audited consolidated financial statements on Form 10-K for the year ended December 31, 2020, from which the consolidated balance sheet as of December 31, 2020 has been derived. The Company’s fiscal quarter ends on the last day of the calendar quarter; however, for certain subsidiaries of the Company, the fiscal quarter periods end on the Saturday that is closest to the last day of the calendar quarter, except for the last quarterly period of the fiscal year. The Company and all its subsidiaries close their books for fiscal years on December 31. For ease of presentation, the quarterly financial statements included herein are described as ending on the last day of the calendar quarter. Certain financial information that is normally included in annual financial statements prepared in accordance with U.S. generally accepted accounting principles ("U.S. GAAP"), but is not required for interim reporting purposes, has been condensed or omitted. Management must make estimates and assumptions that affect the consolidated financial statements and the related footnote disclosures. While management uses its best judgment, actual results may differ from those estimates. Certain reclassifications have been made to the prior period financial statements and notes to conform to the current period presentation.
Restatement For Correction of Immaterial Errors in Previously Issued Consolidated Financial Statements	Restatement For Correction of Immaterial Errors in Previously Issued Consolidated Financial Statements As previously disclosed in the Company’s Form 10-K for the year ended December 31, 2020, during the fourth quarter of 2020, in connection with the preparation of the consolidated financial statements for the year ended December 31, 2020, the Company identified errors in its previously filed annual consolidated financial statements and unaudited quarterly consolidated financial statements. The errors were not material to any individual prior quarterly or annual period. The prior period errors are related primarily to a division of the Company's Electrical Products business within the Diversified Industrial segment ("Electrical Products Misstatements") and were primarily the result of: (1) divisional management override of internal controls, (2) improper segregation of duties, including failure to obtain independent review of recorded accounting entries and accounting analyses and (3) inadequate documentation and support for and/or untimely preparation of account reconciliations. The Electrical Products Misstatements resulted in: (1) improper valuation of inventories and trade receivables, including the related allowance for doubtful accounts; (2) improper recognition of revenue on contracts performed over time; (3) accounts payable and associated expenses not recorded accurately or in the appropriate period; and (4) other errors. The Company assessed the materiality of the errors in its historical annual consolidated financial statements in accordance with SEC Staff Accounting Bulletin ("SAB") Topic 1.M, Materiality , codified in Accounting Standards Codification ("ASC") 250, Accounting Changes and Error Corrections , and concluded that the errors were not material to the previously filed annual consolidated financial statements or corresponding unaudited interim periods but would be material in the aggregate if corrected solely in the consolidated financial statements as of and for the year ended December 31, 2020. In accordance with ASC 250 (SAB Topic 1.N, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements) , the Company corrected for these errors by revising previously filed 2019 annual consolidated financial statements, including the impact to beginning Partners' capital, in connection with the filing of its 2020 Annual Report on Form 10-K. The revised annual consolidated financial statements also included adjustments to correct certain other immaterial errors, including errors that had previously been adjusted for and disclosed as out of period corrections in the period identified. Additionally, in connection with the filing of this Quarterly Report on Form 10-Q, the Company has disclosed the impact of the restatement to the consolidated interim financial statements as of and for the three months ended March 31, 2020 to correct for the errors. The accompanying footnotes have also been corrected to reflect the impact of the revisions of the previously filed 2020 interim consolidated financial statements. Refer to Note 21 - "Restatement of Previously Issued Consolidated Financial Statements" for reconciliations between as reported and as revised quarterly amounts.
Discontinued Operations	Discontinued Operations On January 31, 2020, the Company announced that API Group Limited and certain of its affiliates commenced administration proceedings in the United Kingdom. The purpose of the administration proceedings was to facilitate an orderly sale or wind-down of its United Kingdom operations, which include API Laminates Limited and API Foils Holdings Limited. In the United States, API Americas Inc. voluntarily filed for Chapter 11 proceedings in Bankruptcy Court on February 2, 2020, in order to facilitate the sale or liquidation of its U.S. assets. The API Americas Inc. Chapter 11 bankruptcy proceedings were closed by the Bankruptcy Court on December 21, 2020. The API entities (collectively, "API") were wholly-owned subsidiaries of the Company and were included in the Diversified Industrial segment. The Company deconsolidated API on January 31, 2020 as it no longer held a controlling financial interest as of that date. All references made to financial data in this Quarterly Report on Form 10-Q are to the Company's continuing operations, unless specifically noted. See Note 3 - "Discontinued Operations" for additional information.
Adoption of New Accounting Standards and Accounting Standards Not Yet Effective	Adoption of New Accounting Standards In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 removes specific exceptions to the general principles in Topic 740 in order to reduce the complexity of its application. ASU 2019-12 also improves consistency and simplifies existing guidance by clarifying and amending certain specific areas of Topic 740. The Company adopted ASU 2019-12 on January 1, 2021 and the adoption of this standard did not have a material impact on the Company’s consolidated financial statements. In January 2020, the FASB issued ASU 2020-01, Investments-Equity Securities (Topic 321), Investments - Equity Method and Joint Ventures (Topic 323), and Derivatives and Hedging (Topic 815): Clarifying the Interactions between Topic 321, Topic 323, and Topic 815. ASU 2020-01 clarifies the interaction between accounting standards related to equity securities, equity method investments and certain derivatives, and is expected to reduce diversity in practice and increase comparability of the accounting for these interactions. The Company adopted ASU 2020-01 on January 1, 2021, and the adoption of this standard did not have a material impact on the Company's consolidated financial statements. Accounting Standards Not Yet Effective In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. This 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 over the entire contractual term of the instrument rather than delaying recognition of credit losses until it is probable the loss has been incurred. In May 2019, the FASB issued ASU 2019-05, Financial Instruments-Credit Losses (Topic 326): Targeted Transition Relief. ASU 2019-05 provides entities with an option to irrevocably elect the fair value option, applied on an instrument-by-instrument basis for eligible instruments, that are within the scope of Subtopic 326-20, upon the adoption of Topic 326. The fair value option election does not apply to held-to-maturity debt securities. The new standards were to be effective for the Company's 2020 fiscal year. In November 2019, the FASB issued ASU 2019-10, Financial Instruments-Credit Losses (Topic 326), Derivatives and Hedging (Topic 815), and Leases (Topic 842): Effective Dates . This new standard amended the effective date of Topic 326 for smaller reporting companies until January 1, 2023. A company's determination about whether it is eligible to be a smaller reporting company is based on its most recent determination as of November 15, 2019, in accordance with SEC regulations. As of this date, the Company met the SEC definition of a smaller reporting company. Therefore, the Company will not be required to adopt Topic 326 until January 1, 2023. 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 allowance for loan losses ("ALLL"). 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 end. 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 March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting . ASU 2020-04 is intended to provide temporary optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships and other transactions affected by the discontinuation of the London Interbank Offered Rate, known as LIBOR, or by another reference rate expected to be discontinued. This guidance is effective beginning on March 12, 2020, and the Company may elect to apply the amendments prospectively through December 31, 2022. The Company is currently evaluating the impact this guidance may have on its consolidated financial statements and related disclosures.
