Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization, Basis of Presentation and Recent Accounting Pronouncements	ORGANIZATION, BASIS OF PRESENTATION AND RECENT ACCOUNTING PRONOUNCEMENTS Graham Holdings Company (the Company), is a diversified education and media company. The Company’s Kaplan subsidiary provides a wide variety of educational services, both domestically and outside the United States. The Company’s media operations comprise the ownership and operation of seven television broadcasting stations, several websites and print publications, and a marketing solutions provider. The Company’s other business operations include manufacturing, automotive dealerships and home health and hospice services. Basis of Presentation – The accompanying condensed consolidated financial statements have been prepared in accordance with: (i) generally accepted accounting principles in the United States of America (GAAP) for interim financial information; (ii) the instructions to Form 10-Q; and (iii) the guidance of Rule 10-01 of Regulation S-X under the Securities and Exchange Act of 1934, as amended, for financial statements required to be filed with the Securities and Exchange Commission (SEC). They include the assets, liabilities, results of operations and cash flows of the Company, including its domestic and foreign subsidiaries that are more than 50% owned or otherwise controlled by the Company. As permitted under such rules, certain notes and other financial information normally required by GAAP have been condensed or omitted. Management believes the accompanying condensed consolidated financial statements reflect all normal and recurring adjustments necessary for a fair statement of the Company’s financial position, results of operations, and cash flows as of and for the periods presented herein. The Company’s results of operations for the three months ended March 31, 2019 and 2018 may not be indicative of the Company’s future results. These condensed consolidated financial statements are unaudited and should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 . The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP. Use of Estimates in the Preparation of the Condensed Consolidated Financial Statements – The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported herein. 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. Recently Adopted and Issued Accounting Pronouncements – In February 2016, the Financial Accounting Standards Board (FASB) issued new guidance that requires, among other things, a lessee to recognize a right-of-use asset representing an entity’s right to use the underlying asset for the lease term and a liability for lease payments on its balance sheet, regardless of classification of a lease as operating or financing. For leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities and account for the lease similar to existing guidance for operating leases today. This new guidance supersedes all prior guidance. The guidance is effective for interim and fiscal years beginning after December 15, 2018. The standard provides two methods of adoption under the modified retrospective approach. Under the comparative date method, lessees and lessors are required to recognize and measure leases as of the beginning of the earliest period presented. Under the effective date method, lessees and lessors are required to recognize and measure leases as of the period of adoption. The Company adopted the new guidance on January 1, 2019 using the effective date method. The Company elected the available package of transition practical expedients, which allowed the Company to use its historical assessments of whether contracts are or contain leases, lease classification and initial direct costs. Additionally, the Company elected the transition practical expedient to use hindsight to determine the lease term. Upon adoption of the new guidance, the Company recognized right-of-use assets of $ 369.3 million and lease liabilities of $ 418.3 million . The cumulative effect of the changes to the Company’s Condensed Consolidated Balance Sheets as a result of adopting the new guidance was as follows: Balance as of December 31, 2018 Adjustments Balance as of January 1, 2019 Assets Other current assets $ 82,723 $ (5,595 ) $ 77,128 Lease Right-of-Use Assets — 369,333 369,333 Liabilities Accounts payable and accrued liabilities $ 486,578 $ (14,029 ) $ 472,549 Current portion of lease liabilities — 86,747 86,747 Other Liabilities 57,901 (40,500 ) 17,401 Lease Liabilities — 331,520 331,520

Acquisitions And Dispositions [Abstract]
Acquisitions and Dispositions of Businesses	ACQUISITIONS AND DISPOSITIONS OF BUSINESSES Acquisitions . On January 31, 2019, the Company acquired an interest in two automotive dealerships for cash and the assumption of floor plan payables (see Note 5) . In connection with the acquisition, the automotive subsidiary of the Company borrowed $30 million to finance the acquisition and entered into an interest rate swap to fix the interest rate on the debt at 4.7% per annum (see Note 8) . The Company has a 90% interest in the automotive subsidiary. The Company also entered into a management services agreement with an entity affiliated with Christopher J. Ourisman, a member of the Ourisman Automotive Group family of dealerships. Mr. Ourisman and his team will operate and manage the dealerships. In addition, the Company advanced $3.5 million to the minority shareholder, an entity controlled by Mr. Ourisman, at an interest rate of 6% per annum. The acquisition is expected to provide benefits in the future by diversifying the Company’s business operations and is included in other businesses. During 2018 , the Company acquired eight businesses, five in its education division, one in its healthcare division and two in other businesses for $121.1 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 January and February 2018, Kaplan acquired the assets of i-Human Patients, Inc., a provider of cloud-based, interactive patient encounter simulations for medical and nursing professionals and educators, and another small business in test preparation and international, respectively. These acquisitions are expected to provide strategic benefits in the future. In May 2018, Kaplan acquired a 100% interest in Professional Publications, Inc. (PPI), an independent publisher of professional licensing exam review materials and engineering, surveying, architecture, and interior design licensure exam review, by purchasing all of its issued and outstanding shares. This acquisition is expected to provide certain strategic benefits in the future. This acquisition is included in Professional (U.S.). On July 12, 2018, Kaplan acquired 100% of the issued and outstanding shares of the College for Financial Planning (CFFP), a provider of financial education and training to individuals pursuing the Certified Financial Planner certification, a Master of Science in Personal Financial Planning, or a Master of Science in Finance. The acquisition is expected to expand Kaplan’s financial education product offerings and is included in Professional (U.S.). On July 31, 2018, Dekko acquired 100% of the issued and outstanding shares of Furnlite, Inc., a Fallston, NC-based manufacturer of power and data solutions for the hospitality and residential furniture industries. Dekko’s primary reasons for the acquisition are to complement existing product offerings and to provide potential synergies across the businesses. The acquisition is included in other businesses. In August 2018, SocialCode acquired 100% of the membership interests of Marketplace Strategy (MPS), a Cleveland-based digital marketing agency that provides strategy consulting, optimization services, advertising management and creative solutions on online marketplaces including Amazon. SocialCode’s primary reason for the acquisition is to expand its platform offerings. The acquisition is included in other businesses. In September 2018, Graham Healthcare Group (GHG) acquired the assets of a small business and Kaplan acquired the test preparation and study guide assets of Barron’s Educational Series, a New York-based education publishing company. The acquisitions are expected to complement the healthcare and test preparation services currently offered by GHG and Kaplan, respectively. GHG is included in the healthcare division. The Barron’s Educational Series acquisition is included in test preparation. Acquisition-related costs for acquisitions that closed during the first three months of 2018 were $0.1 million and were expensed as incurred. The aggregate purchase price of the 2018 acquisitions was allocated as follows, based on acquisition date fair values to the following assets and liabilities: Purchase Price Allocation Year Ended (in thousands) December 31, 2018 Accounts receivable $ 2,344 Inventory 1,268 Property, plant and equipment 1,518 Goodwill 41,840 Amortized intangible assets 78,427 Other assets 5,198 Other liabilities (7,678 ) Deferred income taxes (4,900 ) Aggregate purchase price, net of cash acquired $ 118,017 The fair values recorded were based upon valuations. 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 $32.3 million of goodwill for income tax purposes for the acquisitions completed in 2018 . The acquired companies were consolidated into the Company’s financial statements starting on their respective acquisition dates. The following unaudited pro forma financial information presents the Company’s results as if the current year acquisitions had occurred at the beginning of 2018 . The unaudited pro forma information also includes the 2018 acquisitions as if they occurred at the beginning of 2017 : Three Months Ended (in thousands) 2019 2018 Operating revenues $ 705,393 $ 728,632 Net income 82,127 44,854 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. Kaplan University Transaction. On March 22, 2018, the Company closed on the Kaplan University (KU) transaction and recorded a pre-tax gain of $4.3 million in the first quarter of 2018. For financial reporting purposes, Kaplan may receive payment of additional consideration related to the sale of the institutional assets as part of its fee to the extent there are sufficient revenues available after paying all amounts required by the Transition and Operations Support Agreement (TOSA). The Company did not recognize any contingent consideration as part of the initial disposition. In the first quarter of 2019, the Company recorded a $0.2 million contingent consideration gain related to the disposition.

The new vehicle floor plan facility bears interest at variable rates that are based on LIBOR plus 1.15% per annum. The weighted average interest rate for the floor plan facility was 3.5% for the three months ended March 31, 2019 . As of March 31, 2019 , the aggregate capacity under the floor plan facility was $40 million , of which $35.3 million had been utilized, and is included in accounts payable and accrued liabilities in the Condensed Consolidated Balance Sheet. Changes in the vehicle floor plan payable are reported as cash flows from financing activities in the Condensed Consolidated Statements of Cash Flows. The floor plan facility is collateralized by vehicle inventory and other assets of the relevant dealership subsidiary, and contains a number of covenants, including, among others, covenants restricting the dealership subsidiary with respect to the creation of liens and changes in ownership, officers and key management personnel. The Company was in compliance with all of these restrictive covenants as of March 31, 2019 . The floor plan interest expense related to the new vehicle floor plan arrangements is offset by amounts received from manufacturers in the form of floor plan assistance capitalized in inventory and recorded against operating expense in the Condensed Consolidated Statements of Operations when the associated inventory is sold. For the three months ended March 31, 2019 , the Company recognized a reduction in operating expense of $0.4 million related to manufacturer floor plan assistance.

Leases [Abstract]
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 Condensed 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 to ten years or more when it is reasonably certain that the option will be exercised. Leases with a term of twelve months or less are not recorded on the balance sheet; however, lease expense for these leases is recognized on a straight-line basis. The Company has elected the practical expedient to not separate lease components from nonlease components. As such, lease expense includes these nonlease components, when applicable. Fixed lease expense is recognized on a straight-line basis over the lease term. Variable lease expense is recognized when incurred. The Company’s lease agreements do not contain any significant residual value guarantees or restrictive covenants. In some instances, the Company subleases its leased real estate facilities to third parties. The Company does not have significant financing leases. The components of lease expense were as follows: (in thousands) Three Months Ended March 31, 2019 Operating lease cost $ 25,010 Short-term and month-to-month lease cost 4,813 Variable lease cost 4,356 Sublease income (4,652 ) Total net lease cost $ 29,527 In connection with the sale of the KHE Campuses business, the Company is the guarantor of several leases for which it has established ROU assets and lease liabilities (see Note 15). Any lease cost or sublease income related to these leases is recorded in other non-operating income. The total net lease cost related to these leases was $0.3 million for the three months ended March 31, 2019 . Supplemental information related to leases was as follows: (in thousands) Three Months Ended March 31, 2019 Cash Flow Information: Operating cash flows from operating leases (payments) $ 25,840 Right-of-use assets obtained in exchange for new operating lease liabilities (noncash) 30,410 As of March 31, 2019 Balance Sheet Information: Lease right-of-use assets $ 382,050 Current lease liabilities $ 82,429 Noncurrent lease liabilities 337,648 Total lease liabilities $ 420,077 Weighted average remaining lease term (years) 6.8 Weighted average discount rate 3.9 % Maturities of lease liabilities were as follows: (in thousands) March 31, 2019 2019 $ 73,800 2020 89,643 2021 72,055 2022 57,865 2023 49,787 Thereafter 137,671 Total payments 480,821 Less: Imputed interest (60,744 ) Total $ 420,077 As of March 31, 2019, the Company has entered into operating leases, including educational and other facilities, that have not yet commenced that have minimum lease payments of $27.4 million .

(2) The carrying value is net of $0.2 million of unamortized debt issuance costs as of March 31, 2019 and December 31, 2018 , respectively. The Company’s other indebtedness at March 31, 2019 and December 31, 2018 is at an interest rate of 2% and matures in 2026 . On January 31, 2019, the Company’s automotive subsidiary entered into a Commercial Note with SunTrust Bank in an aggregate principal amount of $30 million . The Commercial Note is payable over a 10-year period in monthly installments of $0.25 million , plus accrued and unpaid interest, due on the first of each month, with a final payment on January 31, 2029. The Commercial Note bears interest at LIBOR plus an applicable interest rate of 1.75% or 2% per annum, in each case determined on a quarterly basis based upon the automotive subsidiary’s Adjusted Leverage Ratio. The Commercial Note contains terms and conditions, including remedies in the event of a default by the automotive subsidiary. On the same date, the Company’s automotive subsidiary entered into an interest rate swap agreement with a total notional value of $30 million and a maturity date of January 31, 2029. The interest rate swap agreement will pay the automotive subsidiary variable interest on the $30 million notional amount at the one-month LIBOR, and the automotive subsidiary will pay counterparties a fixed rate of 2.7% , effectively resulting in a total fixed interest rate of 4.7% on the outstanding borrowings at the current applicable margin of 2.0% . The interest rate swap agreement was entered into to convert the variable rate borrowing under the Commercial Note into a fixed rate borrowing. Based on the terms of the interest rate swap agreement and the underlying borrowing, the interest rate swap was determined to be effective and thus qualifies as a cash flow hedge. As such, changes in the fair value of the interest rate swap are recorded in other comprehensive income on the accompanying Condensed Consolidated Balance Sheets until earnings are affected by the variability of cash flows. On May 30, 2018, the Company issued $400 million senior unsecured fixed-rate notes due June 1, 2026 (the Notes). The Notes 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, dated as of May 30, 2018 (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. On June 29, 2018, the Company used the net proceeds from the sale of the Notes, together with cash on hand, to redeem the $400 million of 7.25% notes due February 1, 2019. The Company incurred $11.4 million in debt extinguishment costs in relation to the early termination of the 7.25% notes. In combination with the issuance of the Notes, the Company and certain of the Company’s domestic subsidiaries named therein as guarantors entered into an amended and restated credit agreement providing for a U.S. $300 million five -year revolving credit facility (the Revolving Credit Facility) with each of the lenders party thereto, certain of the Company’s foreign subsidiaries from time to time party thereto as foreign borrowers, Wells Fargo Bank, N.A., as Administrative Agent (Wells Fargo), JPMorgan Chase Bank, N.A., as Syndication Agent, and HSBC Bank USA, N.A. and Bank of America, N.A. as Documentation Agents (the Amended and Restated Credit Agreement), which amends and restates the Company’s existing Five Year Credit Agreement, dated as of June 29, 2015, among the Company, certain of its domestic subsidiaries as guarantors, the several lenders from time to time party thereto, Wells Fargo Bank, N.A., as Administrative Agent and JPMorgan Chase Bank, N.A., as Syndication Agent (the Existing Credit Agreement). The Amended and Restated Credit Agreement amends the Existing Credit Agreement to (i) extend the maturity of the Revolving Credit Facility to May 30, 2023, unless the Company and the lenders agree to further extend the term, (ii) increase the aggregate principal amount of the Revolving Credit Facility to U.S. $300 million , consisting of a U.S. Dollar tranche of U.S. $200 million for borrowings in U.S. Dollars and a multicurrency tranche equivalent to U.S. $100 million for borrowings in U.S. Dollars and certain foreign currencies, (iii) provide for borrowings under the Revolving Credit Facility in U.S. Dollars and certain other foreign currencies specified in the Amended and Restated Credit Agreement, (iv) permit certain foreign subsidiaries of the Company to be added to the Amended and Restated Credit Agreement as foreign borrowers thereunder and (v) effect certain other modifications to the Existing Credit Agreement. Under the Amended and Restated Credit Agreement, the Company is required to pay a commitment fee on a quarterly basis, based on the Company’s leverage ratio, of between 0.15% and 0.25% of the amount of the average daily unused portion of the Revolving Credit Facility. Any borrowings under the Amended and Restated Credit Agreement are made on an unsecured basis and bear interest at the Company’s option, either at (a) a fluctuating interest rate equal to the highest of Wells Fargo’s prime rate, 0.5 percent above the Federal funds rate or the one-month Eurodollar rate plus 1% , or (b) the Eurodollar rate for the applicable currency and interest period as defined in the Amended and Restated Credit Agreement, which is generally a periodic rate equal to LIBOR, CDOR, BBSY or SOR, as applicable, in the case of each of clauses (a) and (b) plus an applicable margin that depends on the Company’s consolidated debt to consolidated adjusted EBITDA (as determined pursuant to the Amended and Restated Credit Agreement, Total Net Leverage Ratio). The Company and its foreign subsidiaries may draw on the Revolving Credit Facility for general corporate purposes. Any outstanding borrowings must be repaid on or prior to the final termination date. The Amended and Restated Credit Agreement contains terms and conditions, including remedies in the event of a default by the Company, typical of facilities of this type and requires the Company to maintain a Total Net Leverage Ratio of not greater than 3.5 to 1.0 and a consolidated interest coverage ratio of at least 3.5 to 1.0 based upon the ratio of consolidated adjusted EBITDA to consolidated interest expense as determined pursuant to the Amended and Restated Credit Agreement. The Company is in compliance with all financial covenants as of March 31, 2019 . During the three months ended March 31, 2019 and 2018 , the Company had average borrowings outstanding of approximately $494.4 million and $496.5 million , respectively, at average annual interest rates of approximately 5.1% and 6.2% , respectively. During the three months ended March 31, 2019 and 2018 , the Company incurred net interest expense of $5.7 million and $6.7 million , respectively. At March 31, 2019 , the fair value of the Company’s 5.75% unsecured notes, based on quoted market prices (Level 2 fair value assessment), totaled $421.0 million , compared with the carrying amount of $394.9 million . At December 31, 2018 , the fair value of the Company’s 5.75% unsecured notes, based on quoted market prices (Level 2 fair value assessment), totaled $406.7 million , compared with the carrying amount of $394.7 million . The carrying value of the Company’s other unsecured debt at March 31, 2019 and December 31, 2018 approximates fair value.

These plans measure the market value of a participant’s balance in a notional investment account that is comprised primarily of mutual funds, which are based on observable market prices. However, since the deferred compensation obligations are not exchanged in an active market, they are classified as Level 2 in the fair value hierarchy. Realized and unrealized gains (losses) on deferred compensation are included in operating income. (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.

Earnings Per Share [Abstract]
Earnings Per Share	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 the 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.

Retirement Benefits, Description [Abstract]
Pension and Postretirement Plans	PENSION AND POSTRETIREMENT PLANS On March 22, 2018, the Company eliminated the accrual of pension benefits for certain Kaplan University employees related to their future service. As a result, the Company remeasured the accumulated and projected benefit obligation of the pension plan as of March 22, 2018, and the Company recorded a curtailment gain in the first quarter of 2018. The new measurement basis was used for the recognition of the Company’s pension benefit following the remeasurement. The curtailment gain on the Kaplan University transaction is included in the gain on the Kaplan University transaction and reported in Other income, net on the Condensed Consolidated Statement of Operations. Defined Benefit Plans. The total benefit arising from the Company’s defined benefit pension plans consists of the following components: Three Months Ended March 31 (in thousands) 2019 2018 Service cost $ 5,221 $ 4,940 Interest cost 11,592 11,255 Expected return on assets (30,838 ) (32,486 ) Amortization of prior service cost 409 42 Recognized actuarial gain (37 ) (1,046 ) Net Periodic Benefit (13,653 ) (17,295 ) Curtailment gain — (806 ) Total Benefit $ (13,653 ) $ (18,101 ) The total cost arising from the Company’s Supplemental Executive Retirement Plan (SERP) consists of the following components: Three Months Ended March 31 (in thousands) 2019 2018 Service cost $ 214 $ 205 Interest cost 1,078 966 Amortization of prior service cost 85 78 Recognized actuarial loss 579 601 Net Periodic Cost $ 1,956 $ 1,850 Defined Benefit Plan Assets. The Company’s defined benefit pension obligations are funded by a portfolio made up of a U.S. stock index fund, 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 plan were allocated as follows: As of March 31, December 31, U.S. equities 53 % 53 % U.S. stock index fund 28 % 28 % U.S. fixed income 13 % 13 % International equities 6 % 6 % 100 % 100 % The Company manages approximately 45% of the pension assets internally, of which the majority is invested in a U.S. stock index fund with the remaining investments in Berkshire Hathaway stock and short-term fixed income securities. The remaining 55% of plan assets are managed by two investment companies. The goal for the investments 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, no more than 25% of the assets it manages in specified international exchanges at the time the investment is made, and no less than 5% of the assets could be invested in fixed-income securities. The other investment manager cannot invest more than 20% of the assets at the time of purchase in the stock of Berkshire Hathaway, 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 March 31, 2019 . 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. At March 31, 2019 and December 31, 2018 , the pension plan held investments in one common stock and one U.S. stock index fund that exceeded 10% of total plan assets. These investments were valued at $1,001.3 million and $945.6 million at March 31, 2019 and December 31, 2018 , respectively, or approximately 43% and 45% , respectively, of total plan assets. Other Postretirement Plans. The total cost arising from the Company’s other postretirement plans consists of the following components: Three Months Ended March 31 (in thousands) 2019 2018 Service cost $ — $ 268 Interest cost 72 170 Amortization of prior service credit (1,841 ) (44 ) Recognized actuarial gain (1,090 ) (922 ) Net Periodic Benefit $ (2,859 ) $ (528 )

Contingencies

Commitments and Contingencies Disclosure [Abstract]
Contingencies	CONTINGENCIES 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, invasion of privacy; trademark, copyright and patent infringement; U.S. False Claims Act (False Claims Act) violations; violations of 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 $45 million . During 2014, certain Kaplan subsidiaries were subject to unsealed cases filed by former employees that include, among other allegations, claims under the False Claims Act relating to eligibility for Title IV funding. The U.S. government declined to intervene in all cases, and, as previously reported, court decisions either dismissed the cases in their entirety or narrowed the scope of their allegations. The remaining case is captioned United States of America ex rel. Carlos Urquilla-Diaz et al. v. Kaplan University et al. (unsealed March 25, 2008). On August 17, 2011, the U.S. District Court for the Southern District of Florida issued a series of rulings in the Diaz case, which included three separate complaints: Diaz, Wilcox and Gillespie. The court dismissed the Wilcox complaint in its entirety; dismissed all False Claims Act allegations in the Diaz complaint, leaving only an individual employment claim; and dismissed in part the Gillespie complaint, thereby limiting the scope and time frame of its False Claims Act allegations regarding compliance with the U.S. Federal Rehabilitation Act. On October 31, 2012, the court entered summary judgment in favor of the Company as to the sole remaining employment claim in the Diaz complaint. On July 16, 2013, the court likewise entered summary judgment in favor of the Company on all remaining claims in the Gillespie complaint. Diaz and Gillespie each appealed to the U.S. Court of Appeals for the Eleventh Judicial Circuit. Arguments on both appeals were heard on February 3, 2015. On March 11, 2015, the appellate court issued a decision affirming the lower court’s dismissal of all of Gillespie’s claims. The appellate court also dismissed three of the four Diaz claims, but reversed and remanded on Diaz’s claim that incentive compensation for admissions representatives was improperly based solely on enrollment counts. Kaplan filed an answer to Diaz’s amended complaint on September 11, 2015. Kaplan filed a motion to dismiss Diaz’s claims, and a hearing was held on December 17, 2015. On March 24, 2016, the Court denied the motion to dismiss. Discovery in the case closed in January 2017. Kaplan filed a motion for summary judgment on February 21, 2017. Summary judgment was granted in full and entered on July 13, 2017. Diaz filed a notice of appeal in September 2017 and filed his initial brief. Kaplan filed a response brief in the third quarter of 2018. In April 2019, the Circuit Court of Appeals affirmed the District Court’s summary judgment in full. On September 3, 2015, Kaplan sold to ECA substantially all of the assets of KHE nationally accredited on-ground Title IV eligible schools (KHE Campuses). The transaction included the transfer of certain real estate leases that were guaranteed by Kaplan. As part of the transaction, Kaplan retained liability for, among other things, obligations arising under certain lease guarantees. ECA is currently in receivership and has terminated all of its higher education operations other than the New England College of Business (NECB). The receiver has repudiated all of ECA’s real estate leases not connected to NECB. Although ECA is required to indemnify Kaplan for any amounts Kaplan must pay due to ECA’s failure to fulfill its obligations under real estate leases guaranteed by Kaplan, ECA’s financial situation and the existence of secured and unsecured creditors make it unlikely that Kaplan will recover from ECA. In the second half of 2018, the Company recorded an estimated $17.5 million in losses on guarantor lease obligations in connection with this transaction in other non-operating expense. The Company continues to monitor the status of these obligations and there was no significant change to estimated losses in the first quarter of 2019. Her Majesty’s Revenue and Customs (HMRC), a department of the U.K. government responsible for the collection of taxes, has raised assessments against the Kaplan U.K. Pathways business for Value Added Tax (VAT) relating to 2017 and earlier years, which have been paid by Kaplan. In September 2017, in a case captioned Kaplan International Colleges UK Limited v. The Commissioners for Her Majesty’s Revenue and Customs , Kaplan challenged these assessments. The Company believes it has met all requirements under U.K. VAT law and expects to recover the £16.1 million receivable related to the assessments and subsequent payments that have been paid. Following a hearing held in January 2019, before the First Tier Tax Tribunal, all issues related to EU law in the case were referred to the Court of Justice of the European Union. If the Company does not prevail in this case, a pre-tax charge of £16.1 million will be recorded to operating expense in the Company’s condensed consolidated statement of operations. In March 2018, HMRC issued new VAT guidance indicating a change of policy in relation to certain aspects of a cost sharing exemption that could impact the U.K. Pathways business adversely if this guidance were to become law. As of March 31, 2019, this guidance had not been incorporated into U.K. law. If Kaplan is not successful in preserving a valid exemption under U.K. VAT law, the U.K. Pathways business would incur additional VAT expense in the future. Department of Education (ED) Program Reviews. The ED has undertaken program reviews at various KHE locations. On February 23, 2015, the ED began a program review assessing KU’s administration of its Title IV and Higher Education Act programs during the 2013-2014 and 2014-2015 award years. In 2018, Kaplan contributed the institutional assets and operations of KU to Purdue Global, and the university became Purdue Global, under the ownership and control of Purdue University. However, Kaplan retains liability for any financial obligations the ED might impose under this program review and that are the result of actions taken during the time that Kaplan owned the institution. On September 28, 2018, the ED issued a Preliminary Program Report (Preliminary Report). This Preliminary Report is not final, and the ED may change the findings in the final report. None of the initial findings in the Preliminary Report carries material financial liability. Although the program review technically covers only the 2013–2015 award years, the ED included a review of the treatment of student financial aid refunds for students who withdrew from a program prior to completion in 2017–2018. KHE cannot predict the outcome of this review, when it will be completed, whether any final findings of non-compliance with financial aid program or other requirements will impact KHE’s operations, or what liability or other limitations the ED might place on KHE or Purdue Global as a result of this review. There are also two open program reviews at campuses that were part of the KHE Campuses business prior to its sale in 2015 to ECA. The ED’s final reports on the program reviews at former KHE Broomall, PA, and Pittsburgh, PA, locations are pending. KHE retains responsibility for any financial obligations resulting from these program reviews. The Company does not expect the open program reviews to have a material impact on KHE; however, the results of open program reviews and their impact on Kaplan’s operations are uncertain.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation – The accompanying condensed consolidated financial statements have been prepared in accordance with: (i) generally accepted accounting principles in the United States of America (GAAP) for interim financial information; (ii) the instructions to Form 10-Q; and (iii) the guidance of Rule 10-01 of Regulation S-X under the Securities and Exchange Act of 1934, as amended, for financial statements required to be filed with the Securities and Exchange Commission (SEC). They include the assets, liabilities, results of operations and cash flows of the Company, including its domestic and foreign subsidiaries that are more than 50% owned or otherwise controlled by the Company. As permitted under such rules, certain notes and other financial information normally required by GAAP have been condensed or omitted. Management believes the accompanying condensed consolidated financial statements reflect all normal and recurring adjustments necessary for a fair statement of the Company’s financial position, results of operations, and cash flows as of and for the periods presented herein. The Company’s results of operations for the three months ended March 31, 2019 and 2018 may not be indicative of the Company’s future results. These condensed consolidated financial statements are unaudited and should be read in conjunction with the Company’s audited consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018 . The year-end condensed consolidated balance sheet data was derived from audited financial statements, but does not include all disclosures required by GAAP.
Use of Estimates in the Preparation of the Condensed Consolidated Financial Statements	Use of Estimates in the Preparation of the Condensed Consolidated Financial Statements – The preparation of the condensed consolidated financial statements in conformity with GAAP requires management to make estimates and judgments that affect the amounts reported herein. 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.
Recently Adopted and Issued Accounting Pronouncements	Recently Adopted and Issued Accounting Pronouncements – In February 2016, the Financial Accounting Standards Board (FASB) issued new guidance that requires, among other things, a lessee to recognize a right-of-use asset representing an entity’s right to use the underlying asset for the lease term and a liability for lease payments on its balance sheet, regardless of classification of a lease as operating or financing. For leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities and account for the lease similar to existing guidance for operating leases today. This new guidance supersedes all prior guidance. The guidance is effective for interim and fiscal years beginning after December 15, 2018. The standard provides two methods of adoption under the modified retrospective approach. Under the comparative date method, lessees and lessors are required to recognize and measure leases as of the beginning of the earliest period presented. Under the effective date method, lessees and lessors are required to recognize and measure leases as of the period of adoption. The Company adopted the new guidance on January 1, 2019 using the effective date method. The Company elected the available package of transition practical expedients, which allowed the Company to use its historical assessments of whether contracts are or contain leases, lease classification and initial direct costs. Additionally, the Company elected the transition practical expedient to use hindsight to determine the lease term. Upon adoption of the new guidance, the Company recognized right-of-use assets of $ 369.3 million and lease liabilities of $ 418.3 million . The cumulative effect of the changes to the Company’s Condensed Consolidated Balance Sheets as a result of adopting the new guidance was as follows: Balance as of December 31, 2018 Adjustments Balance as of January 1, 2019 Assets Other current assets $ 82,723 $ (5,595 ) $ 77,128 Lease Right-of-Use Assets — 369,333 369,333 Liabilities Accounts payable and accrued liabilities $ 486,578 $ (14,029 ) $ 472,549 Current portion of lease liabilities — 86,747 86,747 Other Liabilities 57,901 (40,500 ) 17,401 Lease Liabilities — 331,520 331,520

[3]	Includes U.S. Government Securities, corporate bonds, mutual funds and time deposits.

[5]	Includes Graham Holdings Company’s Deferred Compensation Plan and supplemental savings plan benefits under the Graham Holdings Company’s Supplemental Executive Retirement Plan, which are included in accrued compensation and related benefits.
