Accounting Policies [Abstract]
Summary of Significant Accounting Policies	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation and Principles of Consolidation. The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles (GAAP) in the U.S. and include the assets, liabilities, results of operations and cash flows of the Company and its majority-owned and controlled subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported in the financial statements. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. On an ongoing basis, the Company evaluates its estimates and assumptions. Business Combinations. The purchase price of an acquisition is allocated to the assets acquired, including intangible assets, and liabilities assumed, based on their respective fair values at the acquisition date. Acquisition-related costs are expensed as incurred. The excess of the cost of an acquired entity over the net of the amounts assigned to the assets acquired and liabilities assumed is recognized as goodwill. The net assets and results of operations of an acquired entity are included in the Company’s Consolidated Financial Statements from the acquisition date. Cash and Cash Equivalents. Cash and cash equivalents consist of cash on hand, short-term investments with original maturities of three months or less and investments in money market funds with weighted average maturities of three months or less. Restricted Cash. Restricted cash represents amounts required to be held by non-U.S. higher education institutions for prepaid tuition pursuant to foreign government regulations. These regulations stipulate that the Company has a fiduciary responsibility to segregate certain funds to ensure these funds are only used for the benefit of eligible students. Concentration of Credit Risk. Cash and cash equivalents are maintained with several financial institutions domestically and internationally. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions with investment-grade credit ratings. The Company routinely assesses the financial strength of significant customers, and this assessment, combined with the large number and geographical diversity of its customers, limits the Company’s concentration of risk with respect to receivables from contracts with customers. Allowance for Credit Losses. Accounts receivable have been reduced by an allowance that reflects the current expected credit losses associated with the receivables. The current expected credit losses are estimated based on historical write-offs, current macroeconomic conditions and reasonable and supportable forecasts of future economic conditions. Reserves are also established against specific receivables based on aging category, historical collection experience and management’s evaluation of the financial condition of the customer. The Company generally considers an account past due or delinquent when a student or customer misses a scheduled payment. The Company writes off accounts receivable balances deemed uncollectible against the allowance for credit losses following the passage of a certain period of time, or generally when the account is turned over for collection to an outside collection agency. Investments in Equity Securities. The Company measures its investments in equity securities at fair value with changes in fair value recognized in earnings. The Company elected the measurement alternative to measure cost method investments that do not have readily determinable fair value at cost less impairment, adjusted by observable price changes with any fair value changes recognized in earnings. If the fair value of a cost method investment declines below its cost basis and the decline is considered other than temporary, the Company will record a write-down, which is included in earnings. The Company uses the average cost method to determine the basis of the securities sold. Fair Value Measurements. Fair value measurements are determined based on the assumptions that a market participant would use in pricing an asset or liability based on a three-tiered hierarchy that draws a distinction between market participant assumptions based on (i) observable inputs, such as quoted prices in active markets (Level 1); (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and (iii) unobservable inputs that require the Company to use present value and other valuation techniques in the determination of fair value (Level 3). Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measure. The Company’s assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy. For assets that are measured using quoted prices in active markets, the total fair value is the published market price per unit multiplied by the number of units held, without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are primarily valued by reference to quoted prices of similar assets or liabilities in active markets, adjusted for any terms specific to that asset or liability. The Company measures certain assets—including goodwill; intangible assets; property, plant and equipment; lease right-of-use assets; cost and equity-method investments—at fair value on a nonrecurring basis when they are deemed to be impaired. The fair value of these assets is determined with valuation techniques using the best information available and may include quoted market prices, market comparables and discounted cash flow models. Fair Value of Financial Instruments. The carrying amounts reported in the Company’s Consolidated Financial Statements for cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities, the current portion of deferred revenue and the current portion of debt approximate fair value because of the short-term nature of these financial instruments. The fair value of long-term debt is determined based on a number of observable inputs, including the current market activity of the Company’s publicly traded notes, trends in investor demands and market values of comparable publicly traded debt. The fair value of interest rate hedges are determined based on a number of observable inputs, including time to maturity and market interest rates. Inventories and Contracts in Progress. Inventories and contracts in progress are stated at the lower of cost or net realizable values and are based on the first-in, first-out (FIFO) method. Inventory costs include direct material, direct and indirect labor, and applicable manufacturing overhead. The Company allocates manufacturing overhead based on normal production capacity and recognizes unabsorbed manufacturing costs in earnings. The provision for excess and obsolete inventory is based on management’s evaluation of inventories on hand relative to historical usage, estimated future usage and technological developments. Vehicle inventory is based on the specific identification method. The cost of new and used vehicle inventories includes the cost of any equipment added, reconditioning and transportation. In certain instances, vehicle manufacturers provide incentives which are reflected as a reduction in the carrying value of each vehicle purchased. Property, Plant and Equipment. Property, plant and equipment is recorded at cost and includes interest capitalized in connection with major long-term construction projects. Replacements and major improvements are capitalized; maintenance and repairs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the property, plant and equipment: 3 to 20 years for machinery and equipment; 20 to 50 years for buildings. The costs of leasehold improvements are amortized over the lesser of their useful lives or the terms of the respective leases. Evaluation of Long-Lived Assets. The recoverability of long-lived assets and finite-lived intangible assets is assessed whenever adverse events or changes in circumstances indicate that recorded values may not be recoverable. A long-lived asset is considered to not be recoverable when the undiscounted estimated future cash flows are less than the asset’s recorded value. An impairment charge is measured based on estimated fair market value, determined primarily using estimated future cash flows on a discounted basis. Losses on long-lived assets to be disposed of are determined in a similar manner, but the fair market value would be reduced for estimated costs to dispose. Goodwill and Other Intangible Assets. Goodwill is the excess of purchase price over the fair value of identified net assets of businesses acquired. The Company’s intangible assets with an indefinite life are principally from trade names and trademarks, franchise agreements and Federal Communications Commission (FCC) licenses. Amortized intangible assets are primarily student and customer relationships and trade names and trademarks, with amortization periods up to 15 years. Costs associated with renewing or extending intangible assets are insignificant and expensed as incurred. The Company reviews goodwill and indefinite-lived intangible assets at least annually, as of November 30, for possible impairment. Goodwill and indefinite-lived intangible assets are reviewed for possible impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit or indefinite-lived intangible asset below its carrying value. The Company tests its goodwill at the reporting unit level, which is an operating segment or one level below an operating segment. The Company initially assesses qualitative factors to determine if it is necessary to perform the goodwill or indefinite-lived intangible asset quantitative impairment review. The Company reviews the goodwill and indefinite-lived assets for impairment using the quantitative process if, based on its assessment of the qualitative factors, it determines that it is more likely than not that the fair value of a reporting unit or indefinite-lived intangible asset is less than its carrying value, or if it decides to bypass the qualitative assessment. The Company uses a discounted cash flow model, and, where appropriate, a market value approach is also utilized to supplement the discounted cash flow model, to determine the estimated fair value of its reporting units and indefinite-lived intangible assets. The Company makes assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values to determine the estimated fair value of each reporting unit and indefinite-lived intangible asset. If these estimates or related assumptions change in the future, the Company may be required to record impairment charges. Investments in Affiliates. The Company uses the equity method of accounting for its investments in and earnings or losses of affiliates that it does not control, but over which it exerts significant influence. Significant influence is generally deemed to exist if the Company has an ownership interest in the voting stock of an investee between 20% and 50%. The Company also uses the equity method of accounting for its investments in a partnership or limited liability company with specific ownership accounts, if the Company has an ownership interest of 3% or more. The Company considers whether the fair values of any of its equity method investments have declined below their carrying values whenever adverse events or changes in circumstances indicate that recorded values may not be recoverable. If the Company considered any such decline to be other than temporary (based on various factors, including historical financial results, product development activities and the overall health of the affiliate’s industry), a write-down would be recorded to estimated fair value. The Company records its share of the earnings or losses of its affiliates from their most recent available financial statements. In some instances, the reporting period of the affiliates’ financial statements lag the Company’s reporting period, but such lag is never more than three months. Revenue Recognition. The Company identifies a contract for revenue recognition when there is approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and the collectability of consideration is probable. The Company evaluates each contract to determine the number of distinct performance obligations in the contract, which requires the use of judgment. Education Revenue . Education revenue is primarily derived from postsecondary education and supplementary education services provided both domestically and abroad. Generally, tuition and other fees are paid upfront and recorded in deferred revenue in advance of the date when education services are provided to the student. In some instances, installment billing is available to students, which reduces the amount of cash consideration received in advance of performing the service. The contractual terms and conditions associated with installment billing indicate that the student is liable for the total contract price; therefore, mitigating the Company’s exposure to losses associated with nonpayment. The Company determined the installment billing does not represent a significant financing component. Kaplan International . Kaplan International provides higher education, professional education, and test preparation services and materials to students primarily in the United Kingdom (U.K.), Singapore, and Australia. Some Kaplan International contracts consist of one performance obligation that is a combination of indistinct promises to the student, while other Kaplan International contracts include multiple performance obligations as the promises in the contract are capable of being both distinct and distinct within the context of the contract. One Kaplan International business offers an option whereby students receive future services at a discount that is accounted for as a material right. The transaction price is stated in the contract and known at the time of contract inception; therefore, no variable consideration exists. Revenue is allocated to each performance obligation based on its standalone selling price. Any discounts within the contract are allocated across all performance obligations unless observable evidence exists that the discount relates to a specific performance obligation or obligations in the contract. Kaplan International generally determines standalone selling prices based on prices charged to students. Revenue is recognized ratably over the instruction period or access period for higher education, professional education and test preparation services. Kaplan International generally uses the time elapsed method, an input measure, as it best depicts the simultaneous consumption and delivery of these services. Course materials determined to be a separate performance obligation are recognized at the point in time when control transfers to the student, generally when the products are delivered to the student. One Kaplan International business has a contract with a customer consisting of two performance obligations which consisted entirely of variable consideration at contract inception. The Company allocates revenue to each performance obligation based on the expected cost plus a margin. The margin was determined by a market assessment performed at contract inception. Revenue is recognized over time, using an input method, as the customer simultaneously benefits from the services as delivery occurs. The Company records a contract asset associated with this Kaplan International contract as the right to revenue is dependent on something other than the passage of time. Kaplan Higher Education . KHE primarily provides non-academic operations support services to Purdue University Global (Purdue Global) pursuant to a Transition and Operations Support Agreement (TOSA). This contract has a 30-year term and consists of one performance obligation, which represents a series of daily promises to provide support services to Purdue Global. The transaction price is entirely made up of variable consideration related to the reimbursement of KHE support costs and the KHE fee. The TOSA outlines a payment structure, which dictates how cash will be distributed at the end of Purdue Global’s fiscal year, which is the 30th of June. The collectability of the KHE support costs and KHE fee is entirely dependent on the availability of cash at the end of the fiscal year. This variable consideration is constrained based on fiscal year forecasts prepared for Purdue Global. The forecasts are updated throughout the fiscal year until the uncertainty is ultimately resolved, which is at the end of each Purdue Global fiscal year. As KHE’s performance obligation is made up of a series, the variable consideration is allocated to the distinct service period to which it relates, which is the Purdue Global fiscal year. Support services revenue is recognized over time based on the expenses incurred to date and the percentage of expected reimbursement. KHE fee revenue is also recognized over time based on the amount of Purdue Global revenue recognized to date and the percentage of fee expected to be collected for the fiscal year. The Company used these input measures as Purdue Global simultaneously receives and consumes the benefits of the services provided by KHE. Kaplan Supplemental Education . Supplemental Education offers test preparation services and materials to students, as well as professional training and exam preparation for professional certifications and licensures to students. Generally, Supplemental Education contracts consist of multiple performance obligations as promises for these services are distinct within the context of the contract. The transaction price is stated in the contract and known at the time of contract inception, therefore no variable consideration exists. Revenue is allocated to each performance obligation based on its standalone selling price. Supplemental Education generally determines standalone selling prices based on the prices charged to students and professionals. Any discounts within the contract are allocated across all performance obligations unless observable evidence exists that the discount relates to a specific performance obligation in the contract. Supplemental Education services revenue is recognized ratably over the period of access to the education materials. An estimate of the average access period is developed for each course, and this estimate is evaluated on an ongoing basis and adjusted as necessary. The time elapsed method, an input measure, is used as it best depicts the simultaneous consumption and availability of access to the services. Revenue associated with distinct course materials is recognized at the point in time when control transfers to the student, generally when products are delivered to the student. Supplemental Education offers a guarantee on certain courses that gives students the ability to repeat a course if they are not satisfied with their exam score. The Company accounts for this guarantee as a separate performance obligation. Television Broadcasting Revenue . Television broadcasting revenue at Graham Media Group (GMG) is primarily comprised of television and internet advertising revenue, and retransmission revenue. Television Advertising Revenue . GMG accounts for the series of advertisements included in television advertising contracts as one performance obligation and recognizes advertising revenue over time. The Company elected the right to invoice practical expedient, an output method, as GMG has the right to consideration that equals the value provided to the customer for advertisements delivered to date. As a result of the election to use the right to invoice practical expedient, GMG does not determine the transaction price or allocate any variable consideration at contract inception. Rather, GMG recognizes revenue commensurate with the amount to which GMG has the right to invoice the customer. Payment is typically received in arrears within 60 days of revenue recognition. Retransmission Revenue . Retransmission revenue represents compensation paid by cable, satellite and other multichannel video programming distributors (MVPDs) to retransmit GMG’s stations’ broadcasts in their designated market areas. The retransmission rights granted to MVPDs are accounted for as a license of functional intellectual property as the retransmitted broadcast provides significant standalone functionality. As such, each retransmission contract with an MVPD includes one performance obligation for each station’s retransmission license. GMG recognizes revenue using the usage-based royalty method, in which revenue is recognized in the month the broadcast is retransmitted based on the number of MVPD subscribers and the applicable per user rate identified in the retransmission contract. Payment is typically received in arrears within 60 days of revenue recognition. Manufacturing Revenue . Manufacturing revenue consists primarily of product sales generated by four businesses: Hoover, Dekko, Joyce, and Forney. The Company has determined that each item ordered by the customer is a distinct performance obligation as it has standalone value and is distinct within the context of the contract. For arrangements with multiple performance obligations, the Company initially allocates the transaction price to each obligation based on its standalone selling price, which is the retail price charged to customers. Any discounts within the contract are allocated across all performance obligations unless observable evidence exists that the discount relates to a specific performance obligation or obligations in the contract. The Company sells some products and services with a right of return. This right of return constitutes variable consideration and is constrained from revenue recognition on a portfolio basis, using the expected value method until the refund period expires. The Company recognizes revenue when or as control transfers to the customer. Some manufacturing revenue is recognized ratably over the manufacturing period, if the product created for the customer does not have an alternative use to the Company and the Company has an enforceable right to payment for performance completed to date. The determination of the method by which the Company measures its progress toward the satisfaction of its performance obligations requires judgment. The Company measures its progress for these products using the units delivered method, an output measure. These arrangements represented 21%, 21%, and 23% of the manufacturing revenue recognized for the years ended December 31, 2022, 2021 and 2020, respectively. Other manufacturing revenue is recognized at the point in time when control transfers to the customer, generally when the products are shipped. Some customers have a bill and hold arrangement with the Company. Revenue for bill and hold arrangements is recognized when control transfers to the customer, even though the customer does not have physical possession of the goods. Control transfers when the bill-and-hold arrangement has been requested from the customer, the product is identified as belonging to the customer and is ready for physical transfer, and the product cannot be directed for use by anyone but the customer. Payment terms and conditions vary by contract, although terms generally include a requirement of payment within 90 days of delivery. The Company evaluated the terms of the warranties and guarantees offered by its manufacturing businesses and determined that these should not be accounted for as a separate performance obligation as a distinct service is not identified. Healthcare Revenue . The Company contracts with patients to provide home health or hospice services. Payment is typically received from third-party payors such as Medicare, Medicaid, and private insurers. The payor is a third party to the contract that stipulates the transaction price of the contract. The Company identifies the patient as the party who benefits from its healthcare services and as such, the patient is its customer. The Centers for Medicare and Medicaid Services released a revised reimbursement structure under the Patient Driven Groupings Model (PDGM) for Medicare claims for home healthcare services effective for new and modified revenue contracts beginning on or after January 1, 2020. Home health services contracts generally have one performance obligation to provide home health services to patients. Under the PDGM model, the Company recognizes revenue using the right to invoice practical expedient, an output method, as the contractual right to revenue corresponds directly with the transfer of services to the patient. Given the election of the practical expedient, the Company does not determine the transaction price or allocate any variable consideration at contract inception. Rather, the Company recognizes revenue commensurate with the amount to which it has the right to invoice the customer, which is a function of the average length of stay within each of the two 30 day payment periods. Payment is typically received from Medicare within 30 days after a claim is filed. Medicare is the most common third-party payor for home health services. Home health revenue contracts may be modified to account for changes in the patient’s plan of care. The Company identifies contract modifications when the modification changes the existing enforceable rights and obligations. As modifications to the plan of care modify the original performance obligation, the Company accounts for the contract modification as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. Hospice services contracts generally have one performance obligation to provide healthcare services to patients. The transaction price reflects the amount of revenue the Company expects to receive in exchange for providing these services. As the transaction price for healthcare services is known at the time of contract inception, no variable consideration exists. Hospice service revenue is recognized ratably over the period of care. The Company generally uses the time-elapsed method, an input measure as it best depicts the simultaneous delivery and consumption of healthcare services. Payment is received from third-party payors for hospice services within 60 days after a claim is filed, or in some cases in two installments, one during the contract and one after the services have been provided. Medicare is the most common third-party payor. Other Revenue . The Company recognizes revenue associated with management services it provides to its affiliates. The Company accounts for the management services provided as one performance obligation and recognizes revenue over time as the services are delivered. The Company uses the right to invoice practical expedient, an output method, as the Company’s right to revenue corresponds directly with the value delivered to the affiliate. As a result of the election to use the right to invoice practical expedient, the Company does not determine the transaction price or allocate any variable consideration at contract inception. Rather, the Company recognizes revenue commensurate with the amount to which it has the right to invoice the affiliate, which is based on contractually identified percentages. Payment is received monthly in arrears. Automotive Revenue. The automotive subsidiary generates revenue primarily through the sale of new and used vehicles, the arrangement of vehicle financing, insurance and other service contracts (F&I revenue) and the performance of vehicle repair and maintenance services. New and used vehicle revenue contracts generally contain one performance obligation to deliver the vehicle to the customer in exchange for the stated contract consideration. Revenue is recognized at the point in time when control of the vehicle passes to the customer. F&I revenue is recognized at the point in time when the agreement between the customer and financing, insurance or service provider is executed. As the automotive subsidiary acts as an agent in these F&I revenue transactions, revenue is recognized net of any financing, insurance and service provider costs. Repair and maintenance services revenue is recognized over time, as the service is performed. Other Revenue . Restaurant Revenue. Restaurant revenues consist of sales generated by Clyde’s Restaurant Group (CRG). Food and beverage revenue, net of discounts and taxes, is recognized at the point in time when it is delivered to the customer. Proceeds from the sale of gift cards are recorded as deferred revenue and recognized as revenue upon redemption by the customer. Custom Framing Services Revenue. Framebridge sells custom framing solutions to customers. Custom framing services revenue, net of discounts and taxes, is recognized when the products are delivered to the customer. Proceeds from the sale of gift cards are recorded as deferred revenue and recognized as revenue upon redemption by the customer. Code3 Revenue . Code3 generates media management revenue in exchange for providing social media marketing solutions to its clients. The Company determined that Code3 contracts generally have one performance obligation made up of a series of promises to manage the client’s media spend on advertising platforms for the duration of the contract period. Code3 recognizes revenue, net of media acquisition costs, over time as media management services are delivered to the customer. Generally, Code3 recognizes revenue using the right to invoice practical expedient, an output method, as Code3’s right to revenue corresponds directly with the value delivered to its customer. As a result of the election to use the right to invoice practical expedient, Code3 does not determine the transaction price or allocate any variable consideration at contract inception. Rather, Code3 recognizes revenue commensurate with the amount to which it has the right to invoice the customer which is a function of the cost of social media placement plus a management fee, less any applicable discounts. Payment is typically received within 100 days of revenue recognition. Code3 evaluates whether it is the principal (i.e. presents revenue on a gross basis) or agent (i.e. presents revenue on a net basis) in its contracts. Code3 presents revenue for media management services, net of media acquisition costs, as an agent, as Code3 does not control the media before placement on social media platforms. Leaf Group Revenue. Leaf Group (Leaf) generates revenue through its media and marketplace businesses. Media revenue is primarily derived from advertisements displayed on Leaf’s online media properties. Revenue is recognized over time as the performance obligation is delivered. Revenue is generally recognized based on an output measure including impressions delivered, cost per click or time-based advertisements. Marketplace revenue is primarily derived from the sale of products from Society6 and Saatchi Art Group. Each product ordered generally is accounted for as an individual performance obligation. Product revenue, net of discounts and taxes, is recognized when control of the promised good is transferred to the customer. Other Revenue. Other revenue primarily includes advertising, circulation and subscription revenue from Slate, Decile, Pinna and Foreign Policy. The Company accounts for other advertising revenues consistently with the advertising revenue streams addressed above. Circulation revenue consists of fees that pr

Acquisitions And Dispositions [Abstract]
Acquisitions and Dispositions of Businesses	ACQUISITIONS AND DISPOSITIONS OF BUSINESSES Acquisitions. During 2022, the Company acquired seven businesses: five in healthcare and two in automotive, for $143.2 million in cash and contingent consideration and the assumption of floor plan payables. The assets and liabilities of the companies acquired were recorded at their estimated fair values at the date of acquisition. In August 2022, GHG acquired two small businesses which are included in healthcare. In July 2022, GHG acquired a 100% interest in a multi-state provider of Applied Behavior Analysis clinics. The acquisition is expected to expand the product offerings of the healthcare division and is included in healthcare. On July 5, 2022, the Company’s automotive subsidiary acquired two automotive dealerships, including the real property for the dealership operations. In addition to a cash payment and the assumption of $10.9 million in floor plan payables, the automotive subsidiary borrowed $77.4 million to finance the acquisition. The dealerships are operated and managed by an entity affiliated with Christopher J. Ourisman, a member of the Ourisman Automotive Group family of dealerships. These acquisitions expand the Company’s automotive business operations and are included in automotive. In May 2022, GHG acquired two small businesses which are included in healthcare. During 2021, the Company acquired six businesses: two in education, two in healthcare, one in automotive, and one in other businesses for $392.4 million in cash and contingent consideration and the assumption of floor plan payables. The assets and liabilities of the companies acquired were recorded at their estimated fair values at the date of the acquisition. On June 14, 2021, the Company acquired all of the outstanding common shares of Leaf Group Ltd. for $308.6 million in cash and the assumption of $9.2 million in liabilities related to their previous stock compensation plan, which will be paid in the future. Leaf is a consumer internet company that builds creator-driven brands in lifestyle and home and art design categories. The acquisition is expected to provide benefits in the future by diversifying the Company’s business operations and providing operating synergies with other business units. The Company includes Leaf in other businesses. Kaplan acquired certain assets of Projects in Knowledge, a continuing medical education provider for healthcare professionals, and another small business in November 2021. These acquisitions are expected to build upon Kaplan’s existing customer base in the medical and test preparation fields. Both businesses are included in Kaplan’s supplemental education division. In December 2021, GHG acquired two businesses, a home health business in Florida and a 50.1% interest in Weiss, a physician practice specializing in allergies, asthma and immunology. The minority shareholder of Weiss has an option to put 10% of the shares to the Company annually starting in 2026 and may put all of the shares starting in 2033. The fair value of the redeemable noncontrolling interest in Weiss was $6.6 million at the acquisition date, determined using an income approach. These acquisitions are expected to expand the market the healthcare division serves and are included in healthcare. On December 28, 2021, the Company’s automotive subsidiary acquired a Ford automotive dealership for cash and the assumption of $16.6 million in floor plan payables. In connection with the acquisition, the automotive subsidiary of the Company borrowed $22.5 million to finance the acquisition. The dealership is operated and managed by an entity affiliated with Christopher J. Ourisman, a member of the Ourisman Automotive Group family of dealerships. The acquisition expands the Company’s automotive business operations and is included in automotive. During 2020, the Company acquired three businesses: two in education and one in other businesses for $96.8 million in cash and contingent consideration. The assets and liabilities of the companies acquired were recorded at their estimated fair values at the date of acquisition. In the first three months of 2020, Kaplan acquired two small businesses; one in its supplemental education division and one in its international division. In May 2020, the Company acquired an additional interest in Framebridge, Inc. for cash and contingent consideration that resulted in the Company obtaining control of the investee. Following the acquisition, the Company owns 93.4% of Framebridge. The Company previously accounted for Framebridge under the equity method, and included it in Investments in Affiliates on the Consolidated Balance Sheet (see Note 4). The contingent consideration is primarily based on Framebridge achieving revenue milestones within a specific time period. The fair value of the contingent consideration at the acquisition date was $50.6 million, determined using a Monte Carlo simulation. The fair value of the redeemable noncontrolling interest in Framebridge was $6.0 million as of the acquisition date, determined using a market approach. The minority shareholder has an option to put 20% of the minority shares annually starting in 2024. The acquisition is expected to provide benefits in the future by diversifying the Company’s business operations and is included in other businesses. Acquisition-related costs for acquisitions that closed during 2022, 2021 and 2020 were $1.7 million, $3.0 million and $1.1 million, respectively, and were expensed as incurred. The aggregate purchase price of these acquisitions was allocated as follows, based on acquisition date fair values to the following assets and liabilities: Purchase Price Allocation Year Ended December 31 (in thousands) 2022 2021 2020 Accounts receivable $ 3,172 $ 17,878 $ 745 Inventory 21,278 25,383 3,496 Property, plant and equipment 36,255 13,126 3,346 Lease right-of-use assets 4,773 25,890 6,580 Goodwill 56,163 204,151 73,951 Indefinite-lived intangible assets 41,800 22,200 — Amortized intangible assets 1,200 99,800 14,589 Other assets 481 4,911 975 Deferred income taxes 241 44,975 15,958 Floor plan payables (10,908) (16,636) — Other liabilities (3,798) (52,567) (14,917) Current and noncurrent lease liabilities (5,865) (25,593) (6,593) Redeemable noncontrolling interest (2,164) (6,616) (6,005) Noncontrolling interest (512) — — Aggregate purchase price, net of cash acquired $ 142,116 $ 356,902 $ 92,125 The 2022 fair values recorded were based upon valuations and the estimates and assumptions used in such valuations are subject to change within the measurement period (up to one year from the acquisition date). The recording of deferred tax assets or liabilities and the final amount of residual goodwill is not yet finalized. The 2021 fair values include measurement period adjustments related to accounts receivable, goodwill, amortized intangible assets, current and noncurrent lease liabilities, deferred income taxes and contingent consideration. Goodwill is calculated as the excess of the consideration transferred over the net assets recognized and represents the estimated future economic benefits arising from other assets acquired that could not be individually identified and separately recognized. The goodwill recorded due to these acquisitions is attributable to the assembled workforces of the acquired companies and expected synergies. The Company expects to deduct $38.5 million, $80.6 million and $3.2 million of goodwill for income tax purposes for the acquisitions completed in 2022, 2021 and 2020, respectively. The acquired companies were consolidated into the Company’s financial statements starting on their respective acquisition dates. The Company’s Consolidated Statements of Operations include aggregate revenue and operating income of $153.8 million and $6.3 million, respectively, for the year ended December 31, 2022. The following unaudited pro forma financial information presents the Company’s results as if the current year acquisitions had occurred at the beginning of 2021. The unaudited pro forma information also includes the 2021 acquisitions as if they occurred at the beginning of 2020 and the 2020 acquisitions as if they had occurred at the beginning of 2019: Year Ended December 31 (in thousands) 2022 2021 2020 Operating revenues $ 4,090,272 $ 3,827,486 $ 3,323,427 Net income 81,373 376,478 279,810 These pro forma results were based on estimates and assumptions, which the Company believes are reasonable, and include the historical results of operations of the acquired companies and adjustments for depreciation and amortization of identified assets and the effect of pre-acquisition transaction related expenses incurred by the Company and the acquired entities. The pro forma information does not include efficiencies, cost reductions and synergies expected to result from the acquisitions. They are not the results that would have been realized had these entities been part of the Company during the periods presented and are not necessarily indicative of the Company’s consolidated results of operations in future periods. Disposition of Businesses. In October 2022, the Company entered into an agreement to merge the CyberVista business with CyberWire, Inc. in return for a noncontrolling financial interest in the merged entity, N2K Networks, Inc. (the CyberVista transaction). The Company deconsolidated the CyberVista subsidiary, which was included in other businesses, and accounts for its continuing interest in N2K Networks under the equity method of accounting (see Note 4). In December 2020, the Company completed the sale of Megaphone which was included in other businesses. As a result of these transactions, the Company reported gains in other non-operating income (see Note 16). Other Transactions. In November 2022, a CSI minority shareholder put some shares to the Company, which had a redemption value of $1.2 million. Following the redemption, the Company owns 76.5% of CSI. In March 2021, Hoover’s minority shareholders put the remaining outstanding shares to the Company, which had a redemption value of $3.5 million. Following the redemption, the Company owns 100% of Hoover. As of December 31, 2022, the Company holds a controlling financial interest in GHC One and GHC Two and therefore includes the assets, liabilities, results of operations and cash flows in its consolidated financial statements. GHC One acquired CSI and another small business during 2019. GHC Two acquired Weiss during 2021 and a provider of Applied Behavior Analysis clinics and another small business in 2022. The Company accounts for the minority ownership of the group of senior managers in GHC One and GHC Two as a mandatorily redeemable noncontrolling interest (see Note 2).

This benefit is included in the overall state tax provision for 2021 of $2.2 million reflected above. Deferred income taxes consist of the following: As of December 31 (in thousands) 2022 2021 Employee benefit obligations $ 53,307 $ 64,258 Accounts receivable 3,770 3,554 State income tax loss carryforwards 61,826 63,050 State capital loss carryforwards 36 107 State income tax credit carryforwards 421 511 U.S. Federal income tax loss carryforwards 64,310 69,509 U.S. Federal foreign income tax credit carryforwards 1,271 970 Non-U.S. income tax loss carryforwards 19,937 18,877 Non-U.S. capital loss carryforwards 3,458 3,707 Leases 59,072 63,715 Other 2,350 6,396 Deferred Tax Assets 269,758 294,654 Valuation allowances (62,816) (57,603) Deferred Tax Assets, Net 206,942 237,051 Prepaid pension cost 426,348 594,372 Unrealized gain on marketable equity securities 87,204 138,868 Goodwill and other intangible assets 81,593 103,497 Property, plant and equipment 19,703 15,451 Leases 49,473 51,668 Non-U.S. withholding tax 2,084 2,001 Deferred Tax Liabilities 666,405 905,857 Deferred Income Tax Liabilities, Net $ 459,463 $ 668,806 The Company has $1,049.7 million of state income tax net operating loss carryforwards available to offset future state taxable income. During 2021, the Company recorded $115.4 million of state income tax loss carryforwards as a result of the Leaf acquisition. State income tax loss carryforwards, if unutilized, will start to expire approximately as follows: (in millions) 2023 $ 5.4 2024 7.2 2025 18.1 2026 13.7 2027 17.6 2028 and after 987.7 Total $ 1,049.7 The Company has recorded at December 31, 2022, $61.8 million in deferred state income tax assets, net of U.S. Federal income tax, with respect to these state income tax loss carryforwards. The Company has established $41.6 million in valuation allowances against these deferred state income tax assets, since the Company has determined that it is more likely than not that some of these state tax losses may not be fully utilized in the future to reduce state taxable income. The Company has $306.2 million of U.S. Federal income tax loss carryforwards obtained as a result of prior stock acquisitions. During 2021, the Company recorded $262.5 million of U.S. Federal income tax loss carryforwards as a result of the Leaf acquisition. U.S. Federal income tax loss carryforwards are expected to be fully utilized as follows: (in millions) 2023 $ 27.8 2024 27.8 2025 24.8 2026 14.0 2027 6.6 2028 and after 205.2 Total $ 306.2 The Company has established at December 31, 2022, $64.3 million in U.S. Federal deferred tax assets with respect to these U.S. Federal income tax loss carryforwards. For U.S. Federal income tax purposes, the Company has established U.S. Federal deferred tax assets with respect to $1.3 million of foreign tax credits available to be credited against future U.S. Federal income tax liabilities that will start to expire in 2023 if unutilized. The Company has recorded $1.3 million in valuation allowances against these deferred tax assets since the Company determined that it is more likely than not these foreign tax credit carryforwards may not be utilized in the future to reduce U.S. Federal income taxes. The Company has $91.1 million of non-U.S. income tax loss carryforwards as a result of operating losses and carryforwards that were obtained in part through prior stock acquisitions that are available to offset future non-U.S. taxable income and has recorded, with respect to these losses, $19.9 million in non-U.S. deferred income tax assets. The Company has established $14.4 million in valuation allowances against the deferred tax assets for the portion of non-U.S. tax losses that may not be utilized to reduce future non-U.S. taxable income. The $91.1 million of non-U.S. income tax loss carryforwards consist of $50.7 million in losses that may be carried forward indefinitely; $26.0 million of losses that, if unutilized, will expire in varying amounts through 2027; and $14.4 million of losses that, if unutilized, will start to expire after 2027. The Company has $11.5 million of non-U.S. capital loss carryforwards that may be carried forward indefinitely and are available to offset future non-U.S. capital gains. The Company recorded a $3.5 million non-U.S. deferred income tax asset for these non-U.S. capital loss carryforwards and has established a full valuation allowance against this non-U.S. deferred tax asset since the Company has determined that it is more likely than not that the capital loss carryforwards may not be utilized to reduce taxable income in the future. Deferred tax valuation allowances and changes in deferred tax valuation allowances were as follows: (in thousands) Balance at Beginning of Period Tax Expense and Revaluation Deductions Balance at End of Year Ended December 31, 2022 $ 57,603 $ 7,460 $ (2,247) $ 62,816 December 31, 2021 47,217 13,915 (3,529) 57,603 December 31, 2020 46,243 7,303 (6,329) 47,217 The Company has established $43.2 million in valuation allowances against deferred state tax assets recognized, net of U.S. Federal tax. As stated above, approximately $41.6 million of the valuation allowances, net of U.S. Federal income tax, relate to state income tax loss carryforwards. In most instances, the Company has established valuation allowances against deferred state income tax assets without considering potentially offsetting deferred tax liabilities established with respect to prepaid pension cost and goodwill. Prepaid pension cost and goodwill have not been considered a source of future taxable income for realizing those deferred state tax assets recognized since these temporary differences are not likely to reverse in the foreseeable future. However, certain deferred state tax assets have an indefinite life. As a result, the Company has considered deferred tax liabilities for prepaid pension cost and goodwill as a source of future taxable income for realizing those deferred state tax assets with indefinite lives. The valuation allowances established against deferred state income tax assets may increase or decrease within the next 12 months, based on operating results or the market value of investment holdings. The Company will monitor future results on a quarterly basis to determine whether the valuation allowances provided against deferred state tax assets should be increased or decreased as future circumstances warrant. The Company has established $18.2 million in valuation allowances against non-U.S. deferred tax assets, and, as stated above, $14.4 million of the non-U.S. valuation allowances relate to non-U.S. income tax loss carryforwards and $3.5 million relate to non-U.S. capital loss carryforwards. Valuation allowances established against non-U.S. deferred tax assets are recorded at the education division and other businesses. These non-U.S. valuation allowances may increase or decrease within the next 12 months, based on operating results. As a result, the Company is unable to estimate the potential tax impact, given the uncertain operating environment. The Company will monitor future education division and other businesses’ operating results and projected future operating results on a quarterly basis to determine whether the valuation allowances provided against non-U.S. deferred tax assets should be increased or decreased as future circumstances warrant. The Company estimates that unremitted non-U.S. subsidiary earnings, when distributed, will not be subject to tax except to the extent non-U.S. withholding taxes are imposed. Approximately $2.1 million of deferred tax liabilities remain recorded on the books at December 31, 2022 with respect to future non-U.S. withholding taxes the Company estimated may be imposed on future cash distributions. U.S. Federal and state tax liabilities may be recorded if the investment in non-U.S. subsidiaries become held for sale instead of being held indefinitely, but calculation of the tax due is not practicable. The 2019 U.S. Federal tax return and subsequent years remain open to IRS examination. The Company files income tax returns with the U.S. Federal government and in various state, local and non-U.S. governmental jurisdictions, with the consolidated U.S. Federal tax return filing considered the only major tax jurisdiction. The Company endeavors to comply with tax laws and regulations where it does business, but cannot guarantee that, if challenged, the Company’s interpretation of all relevant tax laws and regulations will prevail and that all tax benefits recorded in the financial statements will ultimately be recognized in full. The following summarizes the Company’s unrecognized tax benefits, excluding interest and penalties, for the respective periods: Year Ended December 31 (in thousands) 2022 2021 2020 Beginning unrecognized tax benefits $ 3,004 $ 1,898 $ 1,572 Increases related to current year tax positions 300 1,061 742 Increases related to prior year tax positions 778 45 656 Decreases related to prior year tax positions (185) — — Decreases related to settlement with tax authorities — — (1,072) Decreases due to lapse of applicable statutes of limitations — — — Ending unrecognized tax benefits $ 3,897 $ 3,004 $ 1,898 The unrecognized tax benefits relate to federal and state research and development tax credits applicable to the 2019 to 2022 tax periods, as well as state income tax filing positions applicable to the 2012 to 2018 and 2020 tax periods. In making these determinations, the Company presumes that taxing authorities pursuing examinations of the Company’s compliance with tax law filing requirements will have full knowledge of all relevant information, and, if necessary, the Company will pursue resolution of disputed tax positions by appeals or litigation. Although the Company cannot predict the timing of resolution with tax authorities, the Company estimates that some of the unrecognized tax benefits may change in the next 12 months due to settlement with the tax authorities. The Company expects that a $1.9 million federal tax benefit and a $2.0 million state tax benefit, net of $0.4 million federal tax expense, will reduce the effective tax rate in the future if the unrecognized tax benefits are recognized. The Company classifies interest and penalties related to uncertain tax positions as a component of interest and other expenses, respectively. As of December 31, 2022, the Company has accrued $0.3 million of interest related to the unrecognized tax benefits. The Company has not accrued any penalties related to the unrecognized tax benefits.

(2) The carrying value is net of $0.1 million of unamortized debt issuance costs as of December 31, 2022 and 2021 . (3) The carrying value is net of $0.1 million of unamortized debt issuance costs as of December 31, 2022 . The Company’s $400 million senior unsecured fixed-rate notes (the Notes), due June 1, 2026, are guaranteed, jointly and severally, on a senior unsecured basis, by certain of the Company’s existing and future domestic subsidiaries, as described in the terms of the indenture. The Notes have a coupon rate of 5.75% per annum, payable semi-annually on June 1 and December 1. The Company may redeem the Notes in whole or in part at any time at the respective redemption prices described in the indenture. At December 31, 2022 and 2021, the fair value of the Notes, based on quoted market prices (Level 2 fair value assessment), totaled $395.1 million and $417.5 million, respectively. On May 3, 2022, the Company amended the revolving credit facility to, among other things, (i) extend the maturity of the facility to May 30, 2027, (ii) eliminate borrowings under separate U.S. dollar and multicurrency tranches, (iii) update certain interest rate benchmarks including replacing USD London Interbank Offered Rate (LIBOR) with SOFR for borrowings denominated in U.S. dollars, (iv) incorporate a sub-facility for the issuance of letters of credit, and (v) allow for applicable margin for borrowings to be determined and adjusted quarterly based on the Company’s Total Net Leverage Ratio. The outstanding balance on the Company’s $300 million unsecured revolving credit facility was $200.2 million as of December 31, 2022, consisting of U.S. dollar borrowings of $140 million with interest payable at SOFR plus 1.375% or prime rate plus 0.375%, and British Pound (GBP) borrowings of £50 million with interest payable at Daily Sterling Overnight Index Average (SONIA) plus 1.375%. On July 5, 2022, the Company’s automotive subsidiary amended its commercial note, dated December 28, 2021, with Truist Bank to, among other things, increase the aggregate loan amount to $71.6 million. The amended commercial note is payable over a 10-year period, with a final payment of the outstanding principal balance due on July 1, 2032. The amended commercial note bears interest at variable rates based on SOFR plus 2.05% per annum. On July 5, 2022, the Company’s automotive subsidiary entered into three additional commercial notes with Truist Bank in an aggregate amount of $27.2 million. The commercial notes are each payable over a 10-year period, with a final payment of the outstanding principal balances due on July 1, 2032. The commercial notes each bear interest at variable rates based on SOFR plus 1.8% per annum. On the same date, the Company’s automotive subsidiary entered into three interest rate swap agreements with a total notional value of $27.2 million and a maturity date of July 1, 2032. The interest rate swap agreements will pay the automotive subsidiary interest on the $27.2 million notional amount based on SOFR plus 1.8% per annum and the automotive subsidiary will pay the counterparty a fixed rate of 4.861% per annum. The new interest rate swap agreements were entered into to convert the variable rate borrowings under these commercial notes into fixed rate borrowings. Based on the terms of the new interest rate swap agreements and the underlying borrowings, the new interest rate swaps were determined to be effective and thus qualify as cash flow hedges. On October 21, 2021, the Company’s automotive subsidiary entered into a commercial note with Truist Bank in an aggregate principal amount of $24.75 million. The commercial note is payable over a 10-year period, with a final payment of the outstanding principal balance on October 1, 2031. The commercial note bears interest at variable rates based on SOFR plus 1.8% per annum. The automotive subsidiary used the net proceeds from this commercial note to repay the outstanding balance on the commercial note due in 2029. On the same date, the Company’s automotive subsidiary rolled its existing interest rate swap into a new interest rate swap agreement with a total notional value of $24.75 million and a maturity date of October 1, 2031. The new interest rate swap agreement will pay the automotive subsidiary variable interest on the $24.75 million notional amount based on SOFR plus 1.8% per annum and the automotive subsidiary will pay the counterparty a fixed rate of 4.118% per annum. The new interest rate swap agreement was entered into to convert the variable rate borrowing under this commercial note into a fixed rate borrowing. Based on the terms of the new interest rate swap agreement and the underlying borrowing, the new interest rate swap was determined to be effective and thus qualifies as a cash flow hedge. On December 2, 2022, the GHG subsidiary amended its loan facility with Pinnacle Bank to extend the maturity of its $6.0 million line of credit to December 2, 2023 and updated the interest rate to be based on SOFR plus 2.85% per annum. The GHG subsidiary had no borrowings outstanding under its line of credit as of December 31, 2022 and 2021. On January 26, 2021, the GHG subsidiary amended its loan facility with Pinnacle Bank to decrease the principal of the term loan to $10.6 million, bearing interest at 4.15% per annum. The fair value of the Company’s other debt, which is based on Level 2 inputs, approximates its carrying value as of December 31, 2022 and 2021. The Company is in compliance with all financial covenants of the revolving credit facility, commercial notes, and Pinnacle Bank term loan as of December 31, 2022. During 2022 and 2021, the Company had average borrowings outstanding of approximately $689.9 million and $545.2 million, respectively, at average annual interest rates of approximately 4.8%. The Company incurred net interest expense of $51.2 million, $30.5 million and $34.4 million during 2022, 2021 and 2020, respectively. For the years ended December 31, 2022, 2021 and 2020, the Company recorded interest expense of $16.5 million, $4.1 million and $8.5 million, respectively, to adjust the fair value of the mandatorily redeemable noncontrolling interest. The fair value of the mandatorily redeemable noncontrolling interest was based on the fair value of the underlying subsidiaries owned by GHC One and GHC Two, after taking into account any debt and other noncontrolling interests of its subsidiary investments. The fair value of the owned subsidiaries is determined by reference to either a discounted cash flow or EBITDA multiple, which approximates fair value (Level 3 fair value assessment).

(2) The Company’s investments in marketable equity securities are held in common shares of U.S. corporations that are actively traded on U.S. exchanges. Price quotes for these shares are readily available. (3) Includes U.S. Government Securities, corporate bonds, mutual funds and time deposits. These investments are valued using a market approach based on the quoted market prices of the security or inputs that include quoted market prices for similar instruments and are classified as either Level 1 or Level 2 in the fair value hierarchy. (4) Included in Deferred Charges and Other Assets. The Company utilized a market approach model using a notional amount of the interest rate swaps multiplied by the observable inputs of time to maturity and market interest rates. (5) Included in Accounts payable and accrued liabilities and Other Liabilities. The Company determined the fair value of the contingent consideration liabilities using either a Monte Carlo simulation, Black-Scholes model, or probability-weighted analysis depending on the type of target included in the contingent consideration requirements (revenue, EBITDA, client retention). All analyses included estimated financial projections for the acquired businesses and acquisition-specific discount rates. (6) Included in Accounts payable and accrued liabilities, and valued based on a valuation model that calculates the differential between the contract price and the market-based forward rate. (7) The fair value of the mandatorily redeemable noncontrolling interest is based on the fair value of the underlying subsidiaries owned by GHC One and GHC Two, after taking into account any debt and other noncontrolling interests of its subsidiary investments. The fair value of the owned subsidiaries is determined using enterprise value analyses which include an equal weighing between guideline public company and discounted cash flow analyses. (8) Included in Other Liabilities. The Company utilized a market approach model using the notional amount of the interest rate swap multiplied by the observable inputs of time to maturity and market interest rates. The following table provides a reconciliation of changes in the Company’s financial liabilities measured at fair value on a recurring basis, using Level 3 inputs: (in thousands) Contingent consideration liabilities Mandatorily redeemable noncontrolling interest As of December 31, 2020 $ 37,174 $ 9,240 Acquisition of business 1,868 — Changes in fair value (1) (5,482) 4,077 Capital contributions — 427 Accretion of value included in net income (1) 1,275 — Settlements or distributions (19,942) (83) Foreign currency exchange rate changes (12) — As of December 31, 2021 14,881 13,661 Acquisition of business 397 — Changes in fair value (1) (6,672) 16,489 Capital contributions — 1,018 Accretion of value included in net income (1) 1,567 — Settlements or distributions (1,750) (323) As of December 31, 2022 $ 8,423 $ 30,845 ____________ (1) Changes in fair value and accretion of value of contingent consideration liabilities are included in Selling, general and administrative expenses and the changes in fair value of mandatorily redeemable noncontrolling interest is included in Interest expense in the Company’s Consolidated Statements of Operations. For the years ended December 31, 2022, 2021 and 2020, the Company recorded goodwill and other long-lived asset impairment charges of $129.0 million, $32.9 million and $30.2 million , respectively (see Note 19). The remeasurement of goodwill and other long-lived assets is classified as a Level 3 fair value assessment due to the significance of unobservable inputs developed in the determination of the fair value. The Company used a discounted cash flow model to determine the estimated fair value of the reporting units, indefinite-lived intangible assets, and other long-lived assets. Where appropriate, a market value approach was also utilized to supplement the discounted cash flow model. The Company made estimates and assumptions regarding future cash flows, royalty rates, discount rates, market values, and long-term growth rates. For the years ended December 31, 2022, 2021 and 2020, the Company recorded gains of $6.9 million , $11.8 million, and $4.2 million, respectively, to equity securities that are accounted for as cost method investments based on observable transactions for identical or similar investments of the same issuer. For the years ended December 31, 2022 and 2020, the Company recorded impairment losses of $1.3 million and $7.3 million, respectively, to equity securities that are accounted for as cost method investments.

Capital Stock, Stock Awards And Stock Options	CAPITAL STOCK, STOCK AWARDS AND STOCK OPTIONS Capital Stock. Each share of Class A common stock and Class B common stock participates equally in dividends. The Class B stock has limited voting rights and as a class has the right to elect 30% of the Board of Directors; the Class A stock has unlimited voting rights, including the right to elect a majority of the Board of Directors. During 2022, 2021, and 2020 the Company purchased a total of 121,761, 93,969, and 406,112 shares, respectively, of its Class B common stock at a cost of approximately $71.4 million, $55.7 million, and $161.8 million, respectively. On September 10, 2020, the Board of Directors authorized the Company to purchase up to 500,000 shares of its Class B Common Stock. The Company did not announce a ceiling price or time limit for the purchases. At December 31, 2022, the Company had remaining authorization from the Board of Directors to purchase up to 148,421 shares of Class B common stock. Stock Awards. In 2012, the Company adopted an incentive compensation plan (the 2012 Plan), which, among other provisions, authorizes the awarding of Class B common stock to key employees in the form of stock awards, stock options and other awards involving the issuance of shares. Stock awards made under the 2012 Plan are primarily subject to the general restriction that stock awarded to a participant will be forfeited and revert to Company ownership if the participant’s employment terminates before the end of a specified period of service to the Company. At December 31, 2022, there were 206,323 shares reserved for issuance under the 2012 Plan, which were all subject to stock awards and stock options outstanding. In 2022, the Company adopted a new incentive compensation plan (the 2022 Plan), which, among other provisions, authorizes the awarding of Class B common stock to key employees and non-employee Directors in the form of stock awards, stock options and other awards involving the issuance of shares. All stock awards, stock options and other awards involving the issuance of shares issued subsequent to the adoption of this plan are covered under this new incentive compensation plan. Stock awards made under the 2022 Plan are primarily subject to the general restriction that stock awarded to a participant will be forfeited and revert to Company ownership if the participant’s employment terminates before the end of a specified period of service to the Company. The number of Class B common shares authorized for issuance under the 2022 Plan is 500,000 shares. At December 31, 2022, there were 499,655 shares reserved for issuance under the 2022 Plan, all of which were available for future awards. Activity related to stock awards under these incentive compensation plans for the year ended December 31, 2022 was as follows: Number of Shares Average Grant-Date Fair Value Beginning of year, unvested 31,571 $ 579.37 Awarded 1,221 605.49 Vested (1,221) 605.49 Forfeited (4,353) 576.45 End of Year, unvested 27,218 579.84 For the share awards outstanding at December 31, 2022, the aforementioned restriction is expected to lapse in 2023 for 11,120 shares, 2025 for 14,098 shares and 2027 for 2,000 shares. Also, early in 2023, the Company issued stock awards of 14,630 shares. Stock-based compensation costs resulting from Company stock awards were $3.4 million, $3.9 million and $4.1 million in 2022, 2021 and 2020, respectively. As of December 31, 2022, there was $4.6 million of total unrecognized compensation expense related to these awards. That cost is expected to be recognized on a straight-line basis over a weighted average period of 1.4 years. Stock Options. Stock options granted under the incentive compensation plans cannot be less than the fair value on the grant date, generally vest over six years and have a maximum term of ten years. Activity related to options outstanding for the year ended December 31, 2022 was as follows: Number of Shares Average Option Price Beginning of year 183,189 $ 612.16 Granted — — Exercised (5,084) 357.35 Expired or forfeited — — End of Year 178,105 619.44 Of the shares covered by options outstanding at the end of 2022, 126,264 are now exercisable; 13,211 are expected to become exercisable in 2023; 12,876 are expected to become exercisable in 2024; 12,877 are expected to become exercisable in 2025; and 12,877 are expected to become exercisable in 2026. For 2022, 2021 and 2020, the Company recorded expense of $1.2 million, $1.7 million and $2.2 million, respectively, related to stock options. Information related to stock options outstanding and exercisable at December 31, 2022, is as follows: Options Outstanding Options Exercisable Range of Exercise Prices Shares Outstanding at 12/31/2022 Weighted Weighted Shares Exercisable at 12/31/2022 Weighted Weighted $427 74,105 7.7 426.86 22,599 7.7 426.86 719 77,258 1.8 719.15 77,258 1.8 719.15 805–872 26,742 3.0 865.02 26,407 2.9 865.26 178,105 4.4 619.44 126,264 3.1 697.39 At December 31, 2022, the intrinsic value for all options outstanding, exercisable and unvested was $13.1 million, $4.0 million and $9.1 million, respectively. The intrinsic value of a stock option is the amount by which the market value of the underlying stock exceeds the exercise price of the option. The market value of the Company’s stock was $604.21 at December 31, 2022. At December 31, 2022, there were 51,841 unvested options related to this plan with an average exercise price of $429.57 and a weighted average remaining contractual term of 7.7 years. At December 31, 2021, there were 65,050 unvested options with an average exercise price of $431.16 and a weighted average remaining contractual term of 8.7 years. As of December 31, 2022, total unrecognized stock-based compensation expense related to stock options was $4.4 million, which is expected to be recognized on a straight-line basis over a weighted average period of approximately 3.7 years. There were 5,084 options exercised during 2022. The total intrinsic value of options exercised during 2022 was $1.2 million; a tax benefit from these option exercises of $0.3 million was realized. There were no options exercised during 2021. There were 77,258 options exercised during 2020. The total intrinsic value of options exercised during 2020 was $11.1 million; a tax benefit from these option exercises of $2.9 million was realized. During 2020, the Company granted 77,258 options at an exercise price above the fair market value of its common stock at the date of grant. The weighted average grant-date fair value of options granted during 2020 was $93.79. No options were granted during 2022 or 2021. The fair value of options at date of grant was estimated using the Black-Scholes method utilizing the following assumptions: 2020 Expected life (years) 8 Interest rate 0.53% Volatility 27.70% Dividend yield 1.45% Other Awards. In 2022, the Company granted a stock award to an executive officer that is subject to price-based vesting conditions. The stock award provides the executive officer the right to receive 1,000 shares of the Company’s Class B common stock each time the Company’s closing share price exceeds a certain share price target for a 90 consecutive day period; the award period expires on December 31, 2027. The grant date fair value of the stock award totaled $3.5 million, which was estimated using a Monte Carlo simulation. The grant date fair value is recognized over the derived service period of each tranche. No shares related to this award vested in 2022 and the Company recognized $1.3 million in stock-based compensation expense related to this award in 2022. For the year ended December 31, 2022, the Company recognized expense of $0.2 million related to the issuance and vesting of 345 shares to non-employee Directors under the 2022 Plan. The Company also maintains a stock option plan at Kaplan. Under the provisions of this plan, options are issued with an exercise price equal to the estimated fair value of Kaplan’s common stock, and options vest ratably over the number of years specified (generally four At December 31, 2022, a Kaplan senior manager holds 7,206 Kaplan restricted shares. The fair value of Kaplan’s common stock is determined by the Company’s compensation committee of the Board of Directors, and in January 2023, the committee set the fair value price at $1,565 per share. No options were awarded during 2022, 2021, or 2020; no options were exercised during 2022, 2021 or 2020; and no options were outstanding at December 31, 2022. Kaplan recorded stock compensation expense of $1.0 million and $1.3 million in 2022 and 2021, respectively, and a stock compensation credit of $1.1 million in 2020. At December 31, 2022, the Company’s accrual balance related to the Kaplan restricted shares totaled $11.3 million. There were no payouts in 2022, 2021 or 2020. Earnings Per Share. The Company’s unvested restricted stock awards contain nonforfeitable rights to dividends and, therefore, are considered participating securities for purposes of computing earnings per share pursuant to the two-class method. The diluted earnings per share computed under the two-class method is lower than the diluted earnings per share computed under the treasury stock method, resulting in the presentation of the lower amount in diluted earnings per share. The computation of earnings per share under the two-class method excludes the income attributable to the unvested restricted stock awards from the numerator and excludes the dilutive impact of those underlying shares from the denominator. The following reflects the Company’s net income and share data used in the basic and diluted earnings per share computations using the two-class method: Year Ended December 31 (in thousands, except per share amounts) 2022 2021 2020 Numerator: Numerator for basic earnings per share: Net income attributable to Graham Holdings Company common stockholders $ 67,079 $ 352,075 $ 300,365 Less: Dividends paid–common stock outstanding and unvested restricted shares (30,712) (30,136) (29,970) Undistributed earnings 36,367 321,939 270,395 Percent allocated to common stockholders 99.43 % 99.36 % 99.45 % 36,160 319,867 268,917 Add: Dividends paid–common stock outstanding 30,540 29,946 29,812 Numerator for basic earnings per share 66,700 349,813 298,729 Add: Additional undistributed earnings due to dilutive stock options — 5 4 Numerator for diluted earnings per share $ 66,700 $ 349,818 $ 298,733 Denominator: Denominator for basic earnings per share: Weighted average shares outstanding 4,823 4,951 5,124 Add: Effect of dilutive stock options 13 14 15 Denominator for diluted earnings per share 4,836 4,965 5,139 Graham Holdings Company Common Stockholders: Basic earnings per share $ 13.83 $ 70.65 $ 58.30 Diluted earnings per share $ 13.79 $ 70.45 $ 58.13 ____________ Earnings per share amounts may not recalculate due to rounding. Diluted earnings per share excludes the following weighted average potential common shares, as the effect would be antidilutive, as computed under the treasury stock method: Year Ended December 31 (in thousands) 2022 2021 2020 Weighted average restricted stock 18 13 12 The 2022, 2021 and 2020 diluted earnings per share amounts exclude the effects of 105,000, 104,000 and 181,258 stock options and contingently issuable shares outstanding, respectively, as their inclusion would have been antidilutive due to a market condition. In 2022, 2021 and 2020, the Company declared regular dividends totaling $6.32, $6.04 and $5.80 per share, respectively.

Pensions and Other Postretirement Plans	PENSIONS AND OTHER POSTRETIREMENT PLANS The Company maintains various pension and incentive savings plans and contributed to multiemployer plans on behalf of certain union-represented employee groups. Most of the Company’s employees are covered by these plans. The Company also provides healthcare and life insurance benefits to certain retired employees. These employees become eligible for benefits after meeting age and service requirements. The Company uses a measurement date of December 31 for its pension and other postretirement benefit plans. Defined Benefit Plans. The Company’s defined benefit pension plans consist of various pension plans and a Supplemental Executive Retirement Plan (SERP) offered to certain executives of the Company. In 2022, a new pension credit retention program was implemented by the Company for certain Graham Healthcare Group employees; the program offers a pension credit up to $50,000 per employee, cliff vested after three years of continuous employment for existing employees and new employees hired from January 1, 2022 through December 31, 2024. The Company recorded $10.5 million in pension service cost expense in 2022 related to this program. In the fourth quarter of 2022, the Company recorded $3.6 million in expenses related to a Separation Incentive Program (SIP) for certain Kaplan employees, which was funded from the assets of the Company’s pension plans. In the second quarter of 2021, the Company recorded $1.1 million in expenses related to a SIP for certain Dekko employees, which was funded from the assets of the Company’s pension plans. In the second quarter of 2020, the Company recorded $6.0 million in expenses related to a SIP for certain Kaplan, Code3 and Decile employees, which was funded from the assets of the Company’s pension plans. In the third quarter of 2020, the Company recorded $7.8 million in expenses related to a SIP for certain Kaplan employees, which was funded from the assets of the Company’s pension plans. The following table sets forth obligation, asset and funding information for the Company’s defined benefit pension plans: Pension Plans As of December 31 (in thousands) 2022 2021 Change in Benefit Obligation Benefit obligation at beginning of year $ 1,088,309 $ 1,095,117 Service cost 32,567 22,991 Interest cost 30,504 26,917 Amendments — 2 Actuarial (gain) loss (219,466) 5,660 Benefits paid (65,240) (63,510) Special termination benefits 3,624 1,132 Benefit Obligation at End of Year $ 870,298 $ 1,088,309 Change in Plan Assets Fair value of assets at beginning of year $ 3,394,823 $ 2,803,422 Actual return on plan assets (801,239) 654,911 Benefits paid (65,240) (63,510) Fair Value of Assets at End of Year $ 2,528,344 $ 3,394,823 Funded Status $ 1,658,046 $ 2,306,514 SERP As of December 31 (in thousands) 2022 2021 Change in Benefit Obligation Benefit obligation at beginning of year $ 112,706 $ 122,299 Service cost 911 1,022 Interest cost 3,289 2,943 Actuarial gain (20,956) (7,640) Benefits paid (5,932) (5,918) Benefit Obligation at End of Year $ 90,018 $ 112,706 Funded Status $ (90,018) $ (112,706) The changes in the Company’s benefit obligations for the pension plans and SERP were primarily due to the recognition of an actuarial gain resulting from an increase to the discount rate used to measure the benefit obligation and benefits paid during the year. The accumulated benefit obligation for the Company’s pension plans at December 31, 2022 and 2021, was $843.6 million and $1,052.7 million, respectively. The accumulated benefit obligation for the Company’s SERP at December 31, 2022 and 2021, was $88.0 million and $112.2 million, respectively.

The Company’s defined benefit pension obligations are funded by a portfolio made up of private investment funds, a U.S. stock index fund, and a relatively small number of stocks and high-quality fixed-income securities that are held by a third-party trustee. The assets of the Company’s pension plans were allocated as follows: As of December 31 2022 2021 U.S. equities 59 % 61 % Private investment funds 16 % 17 % International equities 11 % 9 % U.S. stock index fund 7 % 9 % U.S. fixed income 7 % 4 % 100 % 100 % The Company manages approximately 41% of the pension assets internally, of which the majority is invested in private investment funds with the remaining investments in Berkshire Hathaway stock, a U.S. stock index fund, and short-term fixed-income securities. The remaining 59% of plan assets are managed by two investment companies. The goal of the investment managers is to produce moderate long-term growth in the value of these assets, while protecting them against large decreases in value. Both investment managers may invest in a combination of equity and fixed-income securities and cash. The managers are not permitted to invest in securities of the Company or in alternative investments. One investment manager cannot invest more than 15% of the assets at the time of purchase in the stock of Alphabet and Berkshire Hathaway, and no more than 30% of the assets it manages in specified international exchanges at the time the investment is made. The other investment manager cannot invest more than 20% of the assets at the time of purchase in the stock of Berkshire Hathaway, and no more than 15% of the assets it manages in specified international exchanges at the time the investment is made, and no less than 10% of the assets could be invested in fixed-income securities. Excluding the exceptions noted above, the investment managers cannot invest more than 10% of the assets in the securities of any other single issuer, except for obligations of the U.S. Government, without receiving prior approval from the Plan administrator. In determining the expected rate of return on plan assets, the Company considers the relative weighting of plan assets, the historical performance of total plan assets and individual asset classes and economic and other indicators of future performance. In addition, the Company may consult with and consider the input of financial and other professionals in developing appropriate return benchmarks. The Company evaluated its defined benefit pension plan asset portfolio for the existence of significant concentrations (defined as greater than 10% of plan assets) of credit risk as of December 31, 2022. Types of concentrations that were evaluated include, but are not limited to, investment concentrations in a single entity, type of industry, foreign country and individual fund.

In the fourth quarter of 2022, the Company recorded an $18.4 million gain related to the CyberVista transaction (see Notes 3 and 4). The Company used a market approach to determine the fair value of the noncontrolling financial interest retained in CyberVista through its interest in N2K Networks. In the second quarter of 2020, the Company made an additional investment in Framebridge (see Notes 3 and 4) that resulted in the Company obtaining control of the investee.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Other Commitments	CONTINGENCIES AND OTHER COMMITMENTS Litigation, Legal and Other Matters . The Company and its subsidiaries are subject to complaints and administrative proceedings and are defendants in various civil lawsuits that have arisen in the ordinary course of their businesses, including contract disputes; actions alleging negligence, libel, defamation and invasion of privacy; trademark, copyright and patent infringement; violations of employment laws and applicable wage and hour laws; and statutory or common law claims involving current and former students and employees. Although the outcomes of the legal claims and proceedings against the Company cannot be predicted with certainty, based on currently available information, management believes that there are no existing claims or proceedings that are likely to have a material effect on the Company’s business, financial condition, results of operations or cash flows. However, based on currently available information, management believes it is reasonably possible that future losses from existing and threatened legal, regulatory and other proceedings in excess of the amounts recorded could reach approximately $15 million. In 2015, Kaplan sold substantially all of the assets of the KHE Campuses (KHEC) business to Education Corporation of America. In 2018, certain subsidiaries of Kaplan contributed the institutional assets and operations of KU to a new university: an Indiana nonprofit, public-benefit corporation affiliated with Purdue University, known as Purdue University Global. Kaplan could be held liable to the current owners of KU and the KHEC schools related to the pre-sale conduct of the schools, and the pre-sale conduct of the schools has been and could be the subject of future compliance reviews, regulatory proceedings or lawsuits that could result in monetary liabilities or fines or other sanctions. On May 6, 2021, Kaplan received a notice from the Department of Education (ED) that it would be conducting a fact-finding process pursuant to the borrower defense to repayment (BDTR) regulations to determine the validity of more than 800 BDTR claims and a request for documents related to several of Kaplan’s previously owned schools. Beginning in July 2021, Kaplan started receiving the claims and related information requests. In total, Kaplan received 1,449 borrower defense applications that seek discharge of approximately $35 million in loans, excluding interest. Most claims received are from former KU students. The ED’s process for adjudicating these claims is subject to the borrower defense regulations including those finalized in 2022 and effective July 1, 2023, but it is not clear to what extent the ED will exclude claims based on the underlying statutes of limitations, evidence provided by Kaplan, or any prior investigation related to schools attended by the student applicants. Compared to the previous rule, the new rule in part, expands actions that can give rise to claims for discharge; provides that the borrower’s claim will be presumed true if the institution does not provide any responsive evidence; provides an easier process for group claims; and relies on current program review penalty hearing processes for discharge recoupment. Under the rule, the recoupment process applies only to loans first disbursed after July 1, 2023; however, the discharge process and standards apply to any pending application regardless of loan date. Kaplan believes it has defenses that would bar any student discharge or school liability including that the claims are barred by the applicable statute of limitations, unproven, incomplete and fail to meet regulatory filing requirements. Kaplan expects to vigorously defend any attempt by the ED to hold Kaplan liable for any ultimate student discharges and has responded to all claims with documentary and narrative evidence to refute the allegations, demonstrate their lack of merit, and support the denial of all such claims by the ED. If the claims are successful, the ED may seek reimbursement for the amount discharged from Kaplan. If the ED initiates a reimbursement action against Kaplan following approval of former students’ BDTR applications, Kaplan may be subject to significant liability. In November 2022 the Northern District of California approved the settlement agreement in the lawsuit Sweet v. Cardona . The Plaintiffs in that lawsuit claimed that the ED failed to properly consider and decide pending BDTR claims. As part of the settlement, the ED agreed to discharge loans of borrowers who attended 150 specific schools, including all schools formerly owned by Kaplan, and who had BDTR claims pending as of the June 22, 2022 settlement execution date. This discharge will likely cover each of the 1,449 applications the ED sent to Kaplan and to which Kaplan responded. The ED and the Court made clear that these discharges as part of a settlement are not determinations that the pending BDTR claims are valid and the fact of the settlement discharge cannot be used as evidence of any determination of wrongdoing by the institutions. However, despite the fact that the loans are discharged per the settlement, the ED may still attempt to separately adjudicate the associated BDTR claims and follow the regulatory process for seeking recoupment from the institutions for such claims. On October 27, 2022, the ED released a final rule that among other things, changes the Title IV definition of “Nonprofit” institution to generally exclude from that definition any institution that is an obligor on a debt owed to a former owner of the institution or that maintains a revenue-based service agreement with a former owner of the institution. The final rule has an effective date of July 1, 2023 and could subject Purdue Global to additional regulatory requirements. In August 2018, Purdue University Global received an updated Provisional Program Participation Agreement (PPPA) from the ED which is necessary for continued participation in the federal Title IV programs after the change in ownership from Kaplan to Purdue. The PPPA expired on June 30, 2021 but was extended to June 30, 2022. In August 2022, Purdue University Global received an extended PPPA that is effective through June 30, 2024. Under the extended PPPA, among other restrictions, Purdue University Global must also report information related to known governmental investigations and student complaints on a quarterly basis to the ED. In June 2021, the Committee for Private Education (CPE) in Singapore instructed Kaplan Singapore to cease new enrollments for three marketing diploma programs on both a full and part-time basis due to noncompliance with minimum entry level requirements for admission and to teach out existing students in these programs. On August 23, 2021, the CPE issued the same instructions with respect to the Kaplan Foundation diploma and four information technology diploma programs on both a full and part-time basis. In November 2021, the CPE issued the same instructions with respect to a further 23 full-time or part-time diploma programs. Kaplan Singapore successfully applied for re-registration of certain diploma and additional full-time and part-time programs in 2022. In May 2022, CPE also renewed Kaplan Singapore’s registrations as a private education institution for a four year period expiring in 2026. In 2023, Kaplan Singapore will apply to renew the certification required for private education institutions to enroll international students and offer certain programs. As enrollments in diploma programs and undergraduate degree programs are not yet at levels existing prior to the regulatory action by the CPE in 2021, the impact of such regulatory actions will continue to have an adverse impact on Kaplan Singapore’s revenues, operating results and cash flows in the future while enrollment levels stabilize. Other Commitments. The Company’s broadcast subsidiaries are parties to certain agreements that commit them to purchase programming to be produced in future years. At December 31, 2022, such commitments amounted to approximately $17.3 million. If such programs are not produced, the Company’s commitment would expire without obligation.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policy)	12 Months Ended
	Dec. 31, 2022
Accounting Policies [Abstract]
Basis of Presentation and Principles of Consolidation	Basis of Presentation and Principles of Consolidation. The accompanying Consolidated Financial Statements have been prepared in accordance with generally accepted accounting principles (GAAP) in the U.S. and include the assets, liabilities, results of operations and cash flows of the Company and its majority-owned and controlled subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation.
Use of Estimates	Use of Estimates. The preparation of financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported in the financial statements. Management bases its estimates and assumptions on historical experience and on various other factors that are believed to be reasonable under the circumstances. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may be affected by changes in those estimates. On an ongoing basis, the Company evaluates its estimates and assumptions.
Business Combinations	Business Combinations. The purchase price of an acquisition is allocated to the assets acquired, including intangible assets, and liabilities assumed, based on their respective fair values at the acquisition date. Acquisition-related costs are expensed as incurred. The excess of the cost of an acquired entity over the net of the amounts assigned to the assets acquired and liabilities assumed is recognized as goodwill. The net assets and results of operations of an acquired entity are included in the Company’s Consolidated Financial Statements from the acquisition date.
Cash and Cash Equivalents	Cash and Cash Equivalents. Cash and cash equivalents consist of cash on hand, short-term investments with original maturities of three months or less and investments in money market funds with weighted average maturities of three months or less.
Restricted Cash	Restricted Cash. Restricted cash represents amounts required to be held by non-U.S. higher education institutions for prepaid tuition pursuant to foreign government regulations. These regulations stipulate that the Company has a fiduciary responsibility to segregate certain funds to ensure these funds are only used for the benefit of eligible students.
Concentration of Credit Risk	Concentration of Credit Risk. Cash and cash equivalents are maintained with several financial institutions domestically and internationally. Deposits held with banks may exceed the amount of insurance provided on such deposits. Generally, these deposits may be redeemed upon demand and are maintained with financial institutions with investment-grade credit ratings. The Company routinely assesses the financial strength of significant customers, and this assessment, combined with the large number and geographical diversity of its customers, limits the Company’s concentration of risk with respect to receivables from contracts with customers.
Allowance for Credit Losses	Allowance for Credit Losses. Accounts receivable have been reduced by an allowance that reflects the current expected credit losses associated with the receivables. The current expected credit losses are estimated based on historical write-offs, current macroeconomic conditions and reasonable and supportable forecasts of future economic conditions. Reserves are also established against specific receivables based on aging category, historical
Investments in Equity Securities	Investments in Equity Securities. The Company measures its investments in equity securities at fair value with changes in fair value recognized in earnings. The Company elected the measurement alternative to measure cost method investments that do not have readily determinable fair value at cost less impairment, adjusted by observable price changes with any fair value changes recognized in earnings. If the fair value of a cost method investment declines below its cost basis and the decline is considered other than temporary, the Company will record a write-down, which is included in earnings. The Company uses the average cost method to determine the basis of the securities sold.
Fair Value Measurements	Fair Value Measurements. Fair value measurements are determined based on the assumptions that a market participant would use in pricing an asset or liability based on a three-tiered hierarchy that draws a distinction between market participant assumptions based on (i) observable inputs, such as quoted prices in active markets (Level 1); (ii) inputs other than quoted prices in active markets that are observable either directly or indirectly (Level 2); and (iii) unobservable inputs that require the Company to use present value and other valuation techniques in the determination of fair value (Level 3). Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measure. The Company’s assessment of the significance of a particular input to the fair value measurements requires judgment and may affect the valuation of the assets and liabilities being measured and their placement within the fair value hierarchy. For assets that are measured using quoted prices in active markets, the total fair value is the published market price per unit multiplied by the number of units held, without consideration of transaction costs. Assets and liabilities that are measured using significant other observable inputs are primarily valued by reference to quoted prices of similar assets or liabilities in active markets, adjusted for any terms specific to that asset or liability. The Company measures certain assets—including goodwill; intangible assets; property, plant and equipment; lease right-of-use assets; cost and equity-method investments—at fair value on a nonrecurring basis when they are deemed to be impaired. The fair value of these assets is determined with valuation techniques using the best information available and may include quoted market prices, market comparables and discounted cash flow models.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. The carrying amounts reported in the Company’s Consolidated Financial Statements for cash and cash equivalents, restricted cash, accounts receivable, accounts payable and accrued liabilities, the current portion of deferred revenue and the current portion of debt approximate fair value because of the short-term nature of these financial instruments. The fair value of long-term debt is determined based on a number of observable inputs, including the current market activity of the Company’s publicly traded notes, trends in investor demands and market values of comparable publicly traded debt. The fair value of interest rate hedges are determined based on a number of observable inputs, including time to maturity and market interest rates.
Inventories and Contracts in Progress	Inventories and Contracts in Progress. Inventories and contracts in progress are stated at the lower of cost or net realizable values and are based on the first-in, first-out (FIFO) method. Inventory costs include direct material, direct and indirect labor, and applicable manufacturing overhead. The Company allocates manufacturing overhead based on normal production capacity and recognizes unabsorbed manufacturing costs in earnings. The provision for excess and obsolete inventory is based on management’s evaluation of inventories on hand relative to historical usage, estimated future usage and technological developments. Vehicle inventory is based on the specific identification method. The cost of new and used vehicle inventories includes the cost of any equipment added, reconditioning and transportation. In certain instances, vehicle manufacturers provide incentives which are reflected as a reduction in the carrying value of each vehicle purchased.
Property, Plant and Equipment	Property, Plant and Equipment. Property, plant and equipment is recorded at cost and includes interest capitalized in connection with major long-term construction projects. Replacements and major improvements are capitalized; maintenance and repairs are expensed as incurred. Depreciation is calculated using the straight-line method over the estimated useful lives of the property, plant and equipment: 3 to 20 years for machinery and equipment; 20 to 50 years for buildings. The costs of leasehold improvements are amortized over the lesser of their useful lives or the terms of the respective leases.
Evaluation of Long-Lived Assets	Evaluation of Long-Lived Assets. The recoverability of long-lived assets and finite-lived intangible assets is assessed whenever adverse events or changes in circumstances indicate that recorded values may not be recoverable. A long-lived asset is considered to not be recoverable when the undiscounted estimated future cash flows are less than the asset’s recorded value. An impairment charge is measured based on estimated fair market value, determined primarily using estimated future cash flows on a discounted basis. Losses on long-lived
Goodwill and Other Intangible Assets	Goodwill and Other Intangible Assets. Goodwill is the excess of purchase price over the fair value of identified net assets of businesses acquired. The Company’s intangible assets with an indefinite life are principally from trade names and trademarks, franchise agreements and Federal Communications Commission (FCC) licenses. Amortized intangible assets are primarily student and customer relationships and trade names and trademarks, with amortization periods up to 15 years. Costs associated with renewing or extending intangible assets are insignificant and expensed as incurred. The Company reviews goodwill and indefinite-lived intangible assets at least annually, as of November 30, for possible impairment. Goodwill and indefinite-lived intangible assets are reviewed for possible impairment between annual tests if an event occurs or circumstances change that would more likely than not reduce the fair value of the reporting unit or indefinite-lived intangible asset below its carrying value. The Company tests its goodwill at the reporting unit level, which is an operating segment or one level below an operating segment. The Company initially assesses qualitative factors to determine if it is necessary to perform the goodwill or indefinite-lived intangible asset quantitative impairment review. The Company reviews the goodwill and indefinite-lived assets for impairment using the quantitative process if, based on its assessment of the qualitative factors, it determines that it is more likely than not that the fair value of a reporting unit or indefinite-lived intangible asset is less than its carrying value, or if it decides to bypass the qualitative assessment. The Company uses a discounted cash flow model, and, where appropriate, a market value approach is also utilized to supplement the discounted cash flow model, to determine the estimated fair value of its reporting units and indefinite-lived intangible assets. The Company makes assumptions regarding estimated future cash flows, discount rates, long-term growth rates and market values to determine the estimated fair value of each reporting unit and indefinite-lived intangible asset. If these estimates or related assumptions change in the future, the Company may be required to record impairment charges.
Investments in Affiliates	Investments in Affiliates. The Company uses the equity method of accounting for its investments in and earnings or losses of affiliates that it does not control, but over which it exerts significant influence. Significant influence is generally deemed to exist if the Company has an ownership interest in the voting stock of an investee between 20% and 50%. The Company also uses the equity method of accounting for its investments in a partnership or limited liability company with specific ownership accounts, if the Company has an ownership interest of 3% or more. The Company considers whether the fair values of any of its equity method investments have declined below their carrying values whenever adverse events or changes in circumstances indicate that recorded values may not be recoverable. If the Company considered any such decline to be other than temporary (based on various factors, including historical financial results, product development activities and the overall health of the affiliate’s industry), a write-down would be recorded to estimated fair value. The Company records its share of the earnings or losses of its affiliates from their most recent available financial statements. In some instances, the reporting period of the affiliates’ financial statements lag the Company’s reporting period, but such lag is never more than three months.
Revenue Recognition	Revenue Recognition. The Company identifies a contract for revenue recognition when there is approval and commitment from both parties, the rights of the parties and payment terms are identified, the contract has commercial substance and the collectability of consideration is probable. The Company evaluates each contract to determine the number of distinct performance obligations in the contract, which requires the use of judgment. Education Revenue . Education revenue is primarily derived from postsecondary education and supplementary education services provided both domestically and abroad. Generally, tuition and other fees are paid upfront and recorded in deferred revenue in advance of the date when education services are provided to the student. In some instances, installment billing is available to students, which reduces the amount of cash consideration received in advance of performing the service. The contractual terms and conditions associated with installment billing indicate that the student is liable for the total contract price; therefore, mitigating the Company’s exposure to losses associated with nonpayment. The Company determined the installment billing does not represent a significant financing component. Kaplan International . Kaplan International provides higher education, professional education, and test preparation services and materials to students primarily in the United Kingdom (U.K.), Singapore, and Australia. Some Kaplan International contracts consist of one performance obligation that is a combination of indistinct promises to the student, while other Kaplan International contracts include multiple performance obligations as the promises in the contract are capable of being both distinct and distinct within the context of the contract. One Kaplan International business offers an option whereby students receive future services at a discount that is accounted for as a material right. The transaction price is stated in the contract and known at the time of contract inception; therefore, no variable consideration exists. Revenue is allocated to each performance obligation based on its standalone selling price. Any discounts within the contract are allocated across all performance obligations unless observable evidence exists that the discount relates to a specific performance obligation or obligations in the contract. Kaplan International generally determines standalone selling prices based on prices charged to students. Revenue is recognized ratably over the instruction period or access period for higher education, professional education and test preparation services. Kaplan International generally uses the time elapsed method, an input measure, as it best depicts the simultaneous consumption and delivery of these services. Course materials determined to be a separate performance obligation are recognized at the point in time when control transfers to the student, generally when the products are delivered to the student. One Kaplan International business has a contract with a customer consisting of two performance obligations which consisted entirely of variable consideration at contract inception. The Company allocates revenue to each performance obligation based on the expected cost plus a margin. The margin was determined by a market assessment performed at contract inception. Revenue is recognized over time, using an input method, as the customer simultaneously benefits from the services as delivery occurs. The Company records a contract asset associated with this Kaplan International contract as the right to revenue is dependent on something other than the passage of time. Kaplan Higher Education . KHE primarily provides non-academic operations support services to Purdue University Global (Purdue Global) pursuant to a Transition and Operations Support Agreement (TOSA). This contract has a 30-year term and consists of one performance obligation, which represents a series of daily promises to provide support services to Purdue Global. The transaction price is entirely made up of variable consideration related to the reimbursement of KHE support costs and the KHE fee. The TOSA outlines a payment structure, which dictates how cash will be distributed at the end of Purdue Global’s fiscal year, which is the 30th of June. The collectability of the KHE support costs and KHE fee is entirely dependent on the availability of cash at the end of the fiscal year. This variable consideration is constrained based on fiscal year forecasts prepared for Purdue Global. The forecasts are updated throughout the fiscal year until the uncertainty is ultimately resolved, which is at the end of each Purdue Global fiscal year. As KHE’s performance obligation is made up of a series, the variable consideration is allocated to the distinct service period to which it relates, which is the Purdue Global fiscal year. Support services revenue is recognized over time based on the expenses incurred to date and the percentage of expected reimbursement. KHE fee revenue is also recognized over time based on the amount of Purdue Global revenue recognized to date and the percentage of fee expected to be collected for the fiscal year. The Company used these input measures as Purdue Global simultaneously receives and consumes the benefits of the services provided by KHE. Kaplan Supplemental Education . Supplemental Education offers test preparation services and materials to students, as well as professional training and exam preparation for professional certifications and licensures to students. Generally, Supplemental Education contracts consist of multiple performance obligations as promises for these services are distinct within the context of the contract. The transaction price is stated in the contract and known at the time of contract inception, therefore no variable consideration exists. Revenue is allocated to each performance obligation based on its standalone selling price. Supplemental Education generally determines standalone selling prices based on the prices charged to students and professionals. Any discounts within the contract are allocated across all performance obligations unless observable evidence exists that the discount relates to a specific performance obligation in the contract. Supplemental Education services revenue is recognized ratably over the period of access to the education materials. An estimate of the average access period is developed for each course, and this estimate is evaluated on an ongoing basis and adjusted as necessary. The time elapsed method, an input measure, is used as it best depicts the simultaneous consumption and availability of access to the services. Revenue associated with distinct course materials is recognized at the point in time when control transfers to the student, generally when products are delivered to the student. Supplemental Education offers a guarantee on certain courses that gives students the ability to repeat a course if they are not satisfied with their exam score. The Company accounts for this guarantee as a separate performance obligation. Television Broadcasting Revenue . Television broadcasting revenue at Graham Media Group (GMG) is primarily comprised of television and internet advertising revenue, and retransmission revenue. Television Advertising Revenue . GMG accounts for the series of advertisements included in television advertising contracts as one performance obligation and recognizes advertising revenue over time. The Company elected the right to invoice practical expedient, an output method, as GMG has the right to consideration that equals the value provided to the customer for advertisements delivered to date. As a result of the election to use the right to invoice practical expedient, GMG does not determine the transaction price or allocate any variable consideration at contract inception. Rather, GMG recognizes revenue commensurate with the amount to which GMG has the right to invoice the customer. Payment is typically received in arrears within 60 days of revenue recognition. Retransmission Revenue . Retransmission revenue represents compensation paid by cable, satellite and other multichannel video programming distributors (MVPDs) to retransmit GMG’s stations’ broadcasts in their designated market areas. The retransmission rights granted to MVPDs are accounted for as a license of functional intellectual property as the retransmitted broadcast provides significant standalone functionality. As such, each retransmission contract with an MVPD includes one performance obligation for each station’s retransmission license. GMG recognizes revenue using the usage-based royalty method, in which revenue is recognized in the month the broadcast is retransmitted based on the number of MVPD subscribers and the applicable per user rate identified in the retransmission contract. Payment is typically received in arrears within 60 days of revenue recognition. Manufacturing Revenue . Manufacturing revenue consists primarily of product sales generated by four businesses: Hoover, Dekko, Joyce, and Forney. The Company has determined that each item ordered by the customer is a distinct performance obligation as it has standalone value and is distinct within the context of the contract. For arrangements with multiple performance obligations, the Company initially allocates the transaction price to each obligation based on its standalone selling price, which is the retail price charged to customers. Any discounts within the contract are allocated across all performance obligations unless observable evidence exists that the discount relates to a specific performance obligation or obligations in the contract. The Company sells some products and services with a right of return. This right of return constitutes variable consideration and is constrained from revenue recognition on a portfolio basis, using the expected value method until the refund period expires. The Company recognizes revenue when or as control transfers to the customer. Some manufacturing revenue is recognized ratably over the manufacturing period, if the product created for the customer does not have an alternative use to the Company and the Company has an enforceable right to payment for performance completed to date. The determination of the method by which the Company measures its progress toward the satisfaction of its performance obligations requires judgment. The Company measures its progress for these products using the units delivered method, an output measure. These arrangements represented 21%, 21%, and 23% of the manufacturing revenue recognized for the years ended December 31, 2022, 2021 and 2020, respectively. Other manufacturing revenue is recognized at the point in time when control transfers to the customer, generally when the products are shipped. Some customers have a bill and hold arrangement with the Company. Revenue for bill and hold arrangements is recognized when control transfers to the customer, even though the customer does not have physical possession of the goods. Control transfers when the bill-and-hold arrangement has been requested from the customer, the product is identified as belonging to the customer and is ready for physical transfer, and the product cannot be directed for use by anyone but the customer. Payment terms and conditions vary by contract, although terms generally include a requirement of payment within 90 days of delivery. The Company evaluated the terms of the warranties and guarantees offered by its manufacturing businesses and determined that these should not be accounted for as a separate performance obligation as a distinct service is not identified. Healthcare Revenue . The Company contracts with patients to provide home health or hospice services. Payment is typically received from third-party payors such as Medicare, Medicaid, and private insurers. The payor is a third party to the contract that stipulates the transaction price of the contract. The Company identifies the patient as the party who benefits from its healthcare services and as such, the patient is its customer. The Centers for Medicare and Medicaid Services released a revised reimbursement structure under the Patient Driven Groupings Model (PDGM) for Medicare claims for home healthcare services effective for new and modified revenue contracts beginning on or after January 1, 2020. Home health services contracts generally have one performance obligation to provide home health services to patients. Under the PDGM model, the Company recognizes revenue using the right to invoice practical expedient, an output method, as the contractual right to revenue corresponds directly with the transfer of services to the patient. Given the election of the practical expedient, the Company does not determine the transaction price or allocate any variable consideration at contract inception. Rather, the Company recognizes revenue commensurate with the amount to which it has the right to invoice the customer, which is a function of the average length of stay within each of the two 30 day payment periods. Payment is typically received from Medicare within 30 days after a claim is filed. Medicare is the most common third-party payor for home health services. Home health revenue contracts may be modified to account for changes in the patient’s plan of care. The Company identifies contract modifications when the modification changes the existing enforceable rights and obligations. As modifications to the plan of care modify the original performance obligation, the Company accounts for the contract modification as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. Hospice services contracts generally have one performance obligation to provide healthcare services to patients. The transaction price reflects the amount of revenue the Company expects to receive in exchange for providing these services. As the transaction price for healthcare services is known at the time of contract inception, no variable consideration exists. Hospice service revenue is recognized ratably over the period of care. The Company generally uses the time-elapsed method, an input measure as it best depicts the simultaneous delivery and consumption of healthcare services. Payment is received from third-party payors for hospice services within 60 days after a claim is filed, or in some cases in two installments, one during the contract and one after the services have been provided. Medicare is the most common third-party payor. Other Revenue . The Company recognizes revenue associated with management services it provides to its affiliates. The Company accounts for the management services provided as one performance obligation and recognizes revenue over time as the services are delivered. The Company uses the right to invoice practical expedient, an output method, as the Company’s right to revenue corresponds directly with the value delivered to the affiliate. As a result of the election to use the right to invoice practical expedient, the Company does not determine the transaction price or allocate any variable consideration at contract inception. Rather, the Company recognizes revenue commensurate with the amount to which it has the right to invoice the affiliate, which is based on contractually identified percentages. Payment is received monthly in arrears. Automotive Revenue. The automotive subsidiary generates revenue primarily through the sale of new and used vehicles, the arrangement of vehicle financing, insurance and other service contracts (F&I revenue) and the performance of vehicle repair and maintenance services. New and used vehicle revenue contracts generally contain one performance obligation to deliver the vehicle to the customer in exchange for the stated contract consideration. Revenue is recognized at the point in time when control of the vehicle passes to the customer. F&I revenue is recognized at the point in time when the agreement between the customer and financing, insurance or service provider is executed. As the automotive subsidiary acts as an agent in these F&I revenue transactions, revenue is recognized net of any financing, insurance and service provider costs. Repair and maintenance services revenue is recognized over time, as the service is performed. Other Revenue . Restaurant Revenue. Restaurant revenues consist of sales generated by Clyde’s Restaurant Group (CRG). Food and beverage revenue, net of discounts and taxes, is recognized at the point in time when it is delivered to the customer. Proceeds from the sale of gift cards are recorded as deferred revenue and recognized as revenue upon redemption by the customer. Custom Framing Services Revenue. Framebridge sells custom framing solutions to customers. Custom framing services revenue, net of discounts and taxes, is recognized when the products are delivered to the customer. Proceeds from the sale of gift cards are recorded as deferred revenue and recognized as revenue upon redemption by the customer. Code3 Revenue . Code3 generates media management revenue in exchange for providing social media marketing solutions to its clients. The Company determined that Code3 contracts generally have one performance obligation made up of a series of promises to manage the client’s media spend on advertising platforms for the duration of the contract period. Code3 recognizes revenue, net of media acquisition costs, over time as media management services are delivered to the customer. Generally, Code3 recognizes revenue using the right to invoice practical expedient, an output method, as Code3’s right to revenue corresponds directly with the value delivered to its customer. As a result of the election to use the right to invoice practical expedient, Code3 does not determine the transaction price or allocate any variable consideration at contract inception. Rather, Code3 recognizes revenue commensurate with the amount to which it has the right to invoice the customer which is a function of the cost of social media placement plus a management fee, less any applicable discounts. Payment is typically received within 100 days of revenue recognition. Code3 evaluates whether it is the principal (i.e. presents revenue on a gross basis) or agent (i.e. presents revenue on a net basis) in its contracts. Code3 presents revenue for media management services, net of media acquisition costs, as an agent, as Code3 does not control the media before placement on social media platforms. Leaf Group Revenue. Leaf Group (Leaf) generates revenue through its media and marketplace businesses. Media revenue is primarily derived from advertisements displayed on Leaf’s online media properties. Revenue is recognized over time as the performance obligation is delivered. Revenue is generally recognized based on an output measure including impressions delivered, cost per click or time-based advertisements. Marketplace revenue is primarily derived from the sale of products from Society6 and Saatchi Art Group. Each product ordered generally is accounted for as an individual performance obligation. Product revenue, net of discounts and taxes, is recognized when control of the promised good is transferred to the customer. Other Revenue. Other revenue primarily includes advertising, circulation and subscription revenue from Slate, Decile, Pinna and Foreign Policy. The Company accounts for other advertising revenues consistently with the advertising revenue streams addressed above. Circulation revenue consists of fees that provide customers access to online and print publications. The Company recognizes circulation and subscription revenue ratably over the subscription period beginning on the date that the publication or product is made available to the customer. Circulation revenue contracts are generally annual or monthly subscription contracts that are paid in advance of delivery of performance obligations. Revenue Policy Elections . The Company has elected to account for shipping and handling activities that occur after the customer has obtained control of the good as a fulfillment cost rather than as an additional promised service. Therefore, revenue for these performance obligations is recognized when control of the good transfers to the customer, which is when the good is ready for shipment. The Company accrues the related shipping and handling costs over the period when revenue is recognized. The Company has elected to exclude from the measurement of the transaction price all taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction and collected by the entity from a customer. Revenue Practical Expedients . The Company does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less, (ii) contracts for which the amount of revenue recognized is based on the amount to which the Company has the right to invoice the customer for services performed, (iii) contracts for which the consideration received is a usage-based royalty promised in exchange for a license of intellectual property and (iv) contracts for which variable consideration is allocated entirely to a wholly unsatisfied promise to transfer a distinct good or service that forms part of a single performance obligation. Costs to Obtain a Contract . The Company incurs costs to obtain a contract that are both incremental and expected to be recovered as the costs would not have been incurred if the contract was not obtained and the revenue from the contract exceeds the associated cost. The revenue guidance provides a practical expedient to expense sales commissions as incurred in instances where the amortization period is one year or less. The amortization period is defined in the guidance as the contract term, inclusive of any expected contract renewal periods. The Company has elected to apply this practical expedient to all contracts except for contracts in its education division. In the education division, costs to obtain a contract are amortized over the applicable amortization period except for cases in which commissions paid on initial contracts and renewals are commensurate. The Company amortizes these costs to obtain a contract on a straight-line basis over the amortization period. These expenses are included as cost of services or products in the Company’s Consolidated Statements of Operations.
Leases	Leases. The Company has operating leases for substantially all of its educational facilities, corporate offices and other facilities used in conducting its business, as well as certain equipment. The Company determines if an arrangement is a lease at inception. Operating leases are included in lease right-of-use (ROU) assets, current portion of lease liabilities, and lease liabilities on the Company’s Consolidated Balance Sheets. ROU assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent the Company’s obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. ROU assets also include any initial direct costs, prepaid lease payments and lease incentives received, when applicable. As most of the Company’s leases do not provide an implicit rate, the Company used its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of lease payments. The Company used the incremental borrowing rate on December 31, 2018 for operating leases that commenced prior to that date. The Company’s lease terms may include options to extend or terminate the lease by one Finance leases are included in property, plant and equipment, net, accounts payable and accrued liabilities and other liabilities on the Company’s Consolidated Balance Sheets. The Company primarily has finance leases for its vehicle fleet at the healthcare subsidiary and service loaner vehicles at the automotive subsidiary. Service loaner vehicles are generally purchased from the lessor within six months of contract commencement and upon purchase the vehicles are placed into used vehicle inventory at cost. As of December 31, 2022 and 2021, the Company had
Pensions and Other Postretirement Benefits	Pensions and Other Postretirement Benefits. The Company maintains various pension and incentive savings plans. Most of the Company’s employees are covered by these plans. The Company also provides healthcare and life insurance benefits to certain retired employees. These employees become eligible for benefits after meeting age and service requirements. The Company recognizes the overfunded or underfunded status of a defined benefit postretirement plan as an asset or liability in its Consolidated Balance Sheets and recognizes changes in that funded status in the year in which the changes occur through comprehensive income. The Company measures changes in the funded status of its plans using the projected unit credit method and several actuarial assumptions, the most significant of which are the discount rate, the expected return on plan assets and the rate of compensation increase. The Company uses a measurement date of December 31 for its pension and other postretirement benefit plans.
Self-Insurance	Self-Insurance. The Company uses a combination of insurance and self-insurance for a number of risks, including claims related to employee healthcare and dental care, disability benefits, workers’ compensation, general liability, property damage and business interruption. Liabilities associated with these plans are estimated based on, among other things, the Company’s historical claims experience, severity factors and other actuarial assumptions. The expected loss accruals are based on estimates, and, while the Company believes that the amounts accrued are adequate, the ultimate loss may differ from the amounts provided.
Income Taxes	Income Taxes. The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial statements and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Company records net deferred tax assets to the extent that it believes these assets will more likely than not be realized. In making such determination, the Company considers all available positive and negative evidence, including future reversals of existing taxable temporary differences, projected future taxable income, tax planning strategies and recent financial operations; this evaluation is made on an ongoing basis. In the event the Company were to determine that it was able to realize net deferred income tax assets in the future in excess of their net recorded amount, the Company would record an adjustment to the valuation allowance, which would reduce the provision for income taxes. The Company recognizes a tax benefit from an uncertain tax position when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, based on the technical merits. The Company records a liability for the difference between the benefit recognized and measured for financial statement purposes and the tax position taken or expected to be taken on the Company’s tax return. Changes in the estimate are recorded in the period in which such determination is made.
Foreign Currency Translation	Foreign Currency Translation. Income and expense accounts of the Company’s non-U.S. operations where the local currency is the functional currency are translated into U.S. dollars using the current rate method, whereby operating results are converted at the average rate of exchange for the period, and assets and liabilities are converted at the closing rates on the period end date. Gains and losses on translation of these accounts are accumulated and reported as a separate component of equity and other comprehensive income. Gains and losses on foreign currency transactions, including foreign currency denominated intercompany loans on entities with a functional currency in U.S. dollars, are recognized in the Consolidated Statements of Operations.
Equity-Based Compensation	Equity-Based Compensation. The Company measures compensation expense for awards settled in shares based on the grant date fair value of the award. The Company measures compensation expense for awards settled in cash, or that may be settled in cash, based on the fair value at each reporting date. The Company recognizes the expense over the requisite service period, which is generally the vesting period of the award. Stock award forfeitures are accounted for as they occur.
Earnings Per Share	Earnings Per Share. Basic earnings per share is calculated under the two-class method. The Company treats restricted stock as a participating security due to its nonforfeitable right to dividends. Under the two-class method, the Company allocates to the participating securities their portion of dividends declared and undistributed earnings to the extent the participating securities may share in the earnings as if all earnings for the period had been distributed. Basic earnings per share is calculated by dividing the income available to common stockholders by the weighted average number of common shares outstanding during the period. Diluted earnings per share is calculated similarly except that the weighted average number of common shares outstanding during the period includes the dilutive effect of the assumed exercise of options and restricted stock issuable under the Company’s
Mandatorily Redeemable Noncontrolling Interest	Mandatorily Redeemable Noncontrolling Interest. The mandatorily redeemable noncontrolling interest represents the ownership portion of a group of minority shareholders, consisting of a group of senior managers of the healthcare business, in subsidiaries of Graham Healthcare Group (GHG). The Company established GHC One LLC (GHC One) and GHC Two LLC (GHC Two) as vehicles to invest in a portfolio of healthcare businesses together with the group of senior managers of GHG. As the holder of preferred units, the Company is obligated to contribute 95% of the capital required for the acquisition of portfolio investments with the remaining 5% of the capital coming from the group of senior managers. The operating agreements of GHC One and GHC Two require the dissolution of the entities on March 31, 2026, and March 31, 2029, respectively, at which time the net assets will be distributed to its members. As a preferred unit holder, the Company will receive an amount up to its contributed capital plus a preferred annual return of 8% (guaranteed return) after the group of senior managers has received the redemption of their 5% interest in net assets (manager return). All distributions in excess of the manager and guaranteed return will be paid to common unit holders, which currently comprise the group of senior managers of GHG. The Company may convert its preferred units to common units at any time after which it will receive 80% of all distributions in excess of the manager return, with the remaining 20% of excess distributions going to the group of senior managers as holders of the other common units. The mandatorily redeemable noncontrolling interest is reported as a noncurrent liability at December 31, 2022 and 2021 in the Consolidated Balance Sheets. The Company presents this liability at fair value, which is computed quarterly at the current redemption value. Changes in the redemption value are recorded as interest expense or income in the Company’s Consolidated Statement of Operations.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interest. The Company’s redeemable noncontrolling interest represents the noncontrolling interest in CSI Pharmacy Holding Company, LLC (CSI), which is 76.5% owned, Framebridge, which is 93.4% owned, Weiss, which is 50.1% owned and Skin Clique, which is 51% owned. CSI’s minority shareholders may put up to 50% of their shares to the Company. The first put period began in 2022. A second put period for another tranche of shares begins in 2024. In November 2022, a CSI minority shareholder put some shares to the Company, which had a redemption value of $1.2 million. Prior to the redemption, the Company owned 75% of CSI. The minority shareholder of Framebridge has an option to put 20% of the shares to the Company annually starting in 2024. The minority shareholder of Weiss has an option to put 10% of the shares to the Company annually starting in 2026 and may put all of the shares starting in 2033. The minority shareholders of Skin Clique have the option to put all or a portion of their shares to the Company starting in 2029 and ending in 2032. In March 2021, Hoover’s minority shareholders put the remaining outstanding shares to the Company. Following the redemption, the Company owns 100% of Hoover. Prior to the redemption, the Company owned 98.01% of Hoover. The Company presents the redeemable noncontrolling interests at the greater of its carrying amount or redemption value at the end of each reporting period in the Consolidated Balance Sheets. Changes in the redemption value are recorded to capital in excess of par value in the Company’s Consolidated Balance Sheets.
Comprehensive Income	Comprehensive Income. Comprehensive income consists of net income, foreign currency translation adjustments, net changes in cash flow hedges, and pension and other postretirement plan adjustments.

[1]The Company’s money market investments are included in cash and cash equivalents and the value considers the liquidity of the counterparty.[2]The Company’s investments in marketable equity securities are held in common shares of U.S. corporations that are actively traded on U.S. exchanges. Price quotes for these shares are readily available.[3]Includes U.S. Government Securities, corporate bonds, mutual funds and time deposits. These investments are valued using a market approach based on the quoted market prices of the security or inputs that include quoted market prices for similar instruments and are classified as either Level 1 or Level 2 in the fair value hierarchy.[4]Included in Deferred Charges and Other Assets. The Company utilized a market approach model using a notional amount of the interest rate swaps multiplied by the observable inputs of time to maturity and market interest rates.[5]Included in Accounts payable and accrued liabilities and Other Liabilities. The Company determined the fair value of the contingent consideration liabilities using either a Monte Carlo simulation, Black-Scholes model, or probability-weighted analysis depending on the type of target included in the contingent consideration requirements (revenue, EBITDA, client retention). All analyses included estimated financial projections for the acquired businesses and acquisition-specific discount rates.[6]Included in Other Liabilities. The Company utilized a market approach model using the notional amount of the interest rate swap multiplied by the observable inputs of time to maturity and market interest rates.[7]Included in Accounts payable and accrued liabilities, and valued based on a valuation model that calculates the differential between the contract price and the market-based forward rate.[8]The fair value of the mandatorily redeemable noncontrolling interest is based on the fair value of the underlying subsidiaries owned by GHC One and GHC Two, after taking into account any debt and other noncontrolling interests of its subsidiary investments. The fair value of the owned subsidiaries is determined using enterprise value analyses which include an equal weighing between guideline public company and discounted cash flow analyses.
