Interim Information

Interim Information	6 Months Ended
	Jun. 30, 2024
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Information	INTERIM INFORMATION Readers of this quarterly report should refer to the audited financial statements of Jones Lang LaSalle Incorporated ("JLL," which may also be referred to as "the Company," "we," "us" or "our") for the year ended December 31, 2023, which are included in our 2023 Annual Report on Form 10-K, filed with the United States Securities and Exchange Commission ("SEC") and also available on our website ( www.jll.com ), since we have omitted from this quarterly report certain footnote disclosures which would substantially duplicate those contained in such audited financial statements. You should also refer to the "Summary of Critical Accounting Policies and Estimates" section within Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations and to Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements in our 2023 Annual Report on Form 10-K for further discussion of our significant accounting policies and estimates. Our Consolidated Financial Statements as of June 30, 2024, and for the periods ended June 30, 2024 and 2023, are unaudited. In the opinion of management, we have included all adjustments (consisting solely of normal recurring adjustments) necessary for a fair presentation of the Consolidated Financial Statements for these interim periods. As discussed within our 2023 Annual Report on Form 10-K, specific to our Consolidated Statements of Changes in Equity and Consolidated Statements of Cash Flows, we have made certain presentation changes and recast prior-period information to conform with the current presentation. Historically, our quarterly revenue and profits have tended to increase from quarter to quarter as the year progresses. This is the result of a general focus in the real estate industry on completing transactions by calendar year end, while certain expenses are recognized evenly throughout the year. Growth in our Property Management and Workplace Management businesses as well as other annuity-based services has, to an extent, lessened the seasonality in our revenue and profits during the past several years. Within our Markets Advisory and Capital Markets segments, revenue from transaction-based activities is driven by the size and timing of our clients' transactions and can fluctuate significantly from period to period. Our LaSalle Investment Management ("LaSalle") segment generally earns investment-generated performance fees on clients' real estate investment returns when assets are sold, the timing of which is geared toward the benefit of our clients, as well as co-investment equity gains and losses, primarily dependent on underlying valuations. A significant portion of our compensation and benefits expense is from incentive compensation plans, which we generally accrue throughout the year based on progress toward annual performance targets. This process can result in significant fluctuations in quarterly compensation and benefits expense from period to period. Non-variable operating expenses, which we recognize when incurred during the year, are relatively constant on a quarterly basis. We provide for the effects of income taxes on interim financial statements based on our estimate of the effective tax rate for the full year, which we base on forecasted income by country and expected enacted tax rates. As required, we adjust for the impact of discrete items in the quarters in which they occur. Changes in the geographic mix of income can impact our estimated effective tax rate. As a result of the items mentioned above, the results for the periods ended June 30 are not fully indicative of what our results will be for the full fiscal year.

Subsequent Events & New Account

Subsequent Events & New Accounting Standards	6 Months Ended

Text Block [Abstract]
Subsequent Events & New Accounting Standards	SUBSEQUENT EVENTS & NEW ACCOUNTING STANDARDS Subsequent events In August of 2024, we repurchased a loan, which we originated and sold to Fannie Mae, with an unpaid principal balance ("UPB") of $74.25 million. As this subsequent event represented additional evidence about a matter that existed as of the reporting date, for the period ended June 30, 2024, we recognized $18.0 million within Operating, administrative and other expenses, for the current estimated loss associated with the repurchase in our results. This impact represents the difference between our estimate of the current fair value of the repurchased loan and the repurchase price, including amounts in excess of the UPB for items such as unpaid interest. Recently issued accounting guidance In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. The FASB issued the ASU in response to requests from investors for companies to disclose more information about their financial performance at the segment level. The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. This ASU is effective for annual periods beginning after December 15, 2023, and for interim periods beginning after December 15, 2024, with early adoption permitted. We are evaluating the effect this guidance will have on our segment disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which enhances the income tax disclosures to provide information to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This ASU is effective for annual periods beginning after December 15, 2024, with early adoption permitted. We are evaluating the effect this guidance will have on our tax disclosures.

Revenue from Contract with Customer [Text Block]	REVENUE RECOGNITION Capital Markets revenue excluded from the scope of Accounting Standards Codification Topic 606, Revenue from Contracts with Customers ("ASC Topic 606") Our mortgage banking and servicing operations, comprised of (i) all Loan Servicing revenue and (ii) activities related to mortgage servicing rights ("MSR" or "MSRs") and loan origination fees (included in Investment Sales, Debt/Equity Advisory and Other), are not considered revenue from contracts with customers, and accordingly are excluded from the scope of ASC Topic 606. Such out-of-scope revenue is presented below.

The majority of contract liabilities are recognized as revenue within 90 days. Such contract assets and liabilities are presented below.

As of June 30, 2024, the aggregate amount of transaction price allocated to remaining performance obligations represented less than 5% of our total revenue. In accordance with ASC Topic 606, excluded from the aforementioned remaining performance obligations are (i) amounts attributable to contracts expected to be completed within 12 months and (ii) variable consideration for services performed as a series of daily performance obligations, such as facilities management, property management and LaSalle contracts. A significant portion of our customer contracts, which are not expected to be fulfilled within 12 months, are represented by the contracts within these businesses.

Business Segments

Business Segments	6 Months Ended

Segment Reporting [Abstract]
Business Segments	BUSINESS SEGMENTS We manage and report our operations as five global business segments: (1) Markets Advisory, (2) Capital Markets, (3) Work Dynamics, (4) JLL Technologies and (5) LaSalle. Markets Advisory offers a wide range of real estate services, including agency leasing and tenant representation, property management, advisory and consulting services. Capital Markets service offerings include investment sales, debt and equity advisory, value and risk advisory, and loan servicing. Our Work Dynamics business provides a broad suite of integrated services to occupiers of real estate, including facility and project management, as well as portfolio and other services. Our JLL Technologies segment offers software products, solutions and services, while LaSalle provides investment management services on a global basis to institutional investors and high-net-worth individuals. We allocate all indirect expenses to our segments, other than interest and income taxes, as nearly all expenses incurred benefit one or more of the segments. Allocated expenses primarily consist of corporate functional costs across the globe, which we allocate to the business segments using an expense-specific driver-based methodology. The Chief Operating Decision Maker ("CODM") of JLL measures and evaluates the segment results based on Adjusted EBITDA for purposes of making decisions about allocating resources and assessing performance. Adjusted EBITDA does not include (i) Restructuring and acquisition charges, (ii) gain/loss on disposal, (iii) interest on employee loans, net of forgiveness, (iv) Equity earnings/losses for JLL Technologies and LaSalle, (v) net non-cash MSR and mortgage banking derivative activity, (vi) Interest expense, net of interest income, (vii) Income tax provision (benefit) and (viii) Depreciation and amortization, which are otherwise included in Net income on the Consolidated Statements of Comprehensive Income. In the first quarter of 2024, we revised the definition of segment Adjusted EBITDA to exclude certain Equity earnings/losses from investments. The impact of this revision is limited to the JLL Technologies and LaSalle segments. Comparable periods have been recast to conform to the revised presentation. Equity earnings/losses from unconsolidated operating ventures (not investments) remain included in Adjusted EBITDA.

BUSINESS COMBINATIONS, GOODWILL AND OTHER INTANGIBLE ASSETS [Abstract]
Business Combinations, Goodwill and Other Intangible Assets	BUSINESS COMBINATIONS, GOODWILL AND OTHER INTANGIBLE ASSETS 2024 Business Combinations Activity During the six months ended June 30, 2024, we completed one strategic acquisition. This strategic acquisition is presented below. Acquired Company Quarter of Acquisition Country Primary Segment SKAE Power Solutions (SKAE) Q2 United States Work Dynamics Aggregate terms of our acquisitions included: (i) cash paid at closing of $39.3 million, (ii) guaranteed deferred consideration of $5.8 million and (iii) contingent earn-out consideration of $11.0 million, payable upon satisfaction of certain performance conditions and which we have initially recorded at their respective acquisition date fair value. A preliminary allocation of purchase consideration resulted in (i) goodwill of $40.4 million, (ii) identifiable intangibles of $14.9 million and (iii) other net assets (acquired assets less assumed liabilities) of $0.8 million. As of June 30, 2024, we have not completed our analysis to assign fair values to all of the identifiable intangible and tangible assets acquired and, therefore, we may further refine the purchase price allocations for this acquisition during the open measurement period. During the six months ended June 30, 2024 and 2023, we paid $4.9 million and $22.0 million, respectively, for deferred business acquisition and earn-out obligations for acquisitions completed in prior years. Earn-Out Payments ($ in millions) June 30, 2024 December 31, 2023 Number of acquisitions with earn-out payments subject to the achievement of certain performance criteria 13 14 Maximum earn-out payments (undiscounted) $ 113.6 100.0 Short-term earn-out liabilities (fair value) (1) 11.4 12.0 Long-term earn-out liabilities (fair value) (1) 42.3 45.5 (1) Included in Other current and Other long-term liabilities on the Consolidated Balance Sheets. Assuming the achievement of the applicable performance criteria, we anticipate making these earn-out payments over the next four years. Refer to Note 8, Fair Value Measurements, and Note 11, Restructuring and Acquisition Charges, for additional discussion of our earn-out liabilities. Goodwill and Other Intangible Assets Goodwill and unamortized intangibles as of June 30, 2024 consisted of: (i) goodwill of $4,609.2 million, (ii) identifiable intangibles of $695.6 million amortized over their remaining finite useful lives and (iii) $48.3 million of identifiable intangibles with indefinite useful lives that are not amortized. Notable portions of our goodwill and unamortized intangibles are denominated in currencies other than the U.S. dollar, which means a portion of the movements in the reported book value of these balances is attributable to movements in foreign currency exchange rates. The following table details, by reporting segment, movements in goodwill.

We have maximum potential unfunded commitments to direct investments or investment vehicles of $254.7 million and $11.7 million as of June 30, 2024 for our LaSalle Investment Management business and JLL Technologies, respectively. LaSalle Investment Management’s potential unfunded commitments decline in the second quarter of 2024 was primarily due to the legal release of a $60.3 million remaining unfunded commitment in a specific underlying fund. Impairment There were no significant other-than-temporary impairment charges on investments for the six months ended June 30, 2024 and 2023. Fair Value We report a majority of our investments at fair value. For such investments, we increase or decrease our investment each reporting period by the change in the fair value and we report these fair value adjustments in our Consolidated Statements of Comprehensive Income within Equity earnings/losses. The table below shows the movement in our investments reported at fair value.

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	FAIR VALUE MEASUREMENTS We measure certain assets and liabilities in accordance with ASC Topic 820, Fair Value Measurements and Disclosures , which defines fair value as the price that would be received for an asset, or paid to transfer a liability, in an orderly transaction between market participants on the measurement date. In addition, it establishes a framework for measuring fair value according to the following three-tier fair value hierarchy: • Level 1 - Quoted prices for identical assets or liabilities in active markets accessible as of the measurement date; • Level 2 - Inputs, other than quoted prices in active markets, that are observable either directly or indirectly; and • Level 3 - Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. Financial Instruments Our financial instruments include Cash and cash equivalents, Trade receivables, Notes and other receivables, Reimbursable receivables, Warehouse receivables, restricted cash, contract assets, Accounts payable, Reimbursable payables, Short-term borrowings, contract liabilities, Warehouse facilities, Credit facility, Long-term debt and foreign currency forward contracts. The carrying amounts of Cash and cash equivalents, Trade receivables, Notes and other receivables, Reimbursable receivables, restricted cash, contract assets, Accounts payable, Reimbursable payables, contract liabilities and the Warehouse facilities approximate their estimated fair values due to the short-term nature of these instruments. The carrying values of our Credit facility and Short-term borrowings approximate their estimated fair values given the variable interest rate terms and market spreads. We estimated the fair value of our Long-term debt using dealer quotes that are Level 2 inputs in the fair value hierarchy. The fair value and carrying value of our debt are presented in the following table. (in millions) June 30, 2024 December 31, 2023 Long-term debt, fair value $ 789.0 798.1 Long-term debt, carrying value, net of debt issuance costs 767.9 779.3 Investments at Fair Value - Net Asset Value ("NAV") We report a significant portion of our investments at fair value. For such investments, we increase or decrease our investment each reporting period by the change in the fair value, and we report these fair value adjustments in our Consolidated Statements of Comprehensive Income within Equity earnings/losses. For a subset of our investments reported at fair value, we estimate the fair value using the NAV per share (or its equivalent) our investees provide. Critical inputs to NAV estimates included valuations of the underlying real estate assets and borrowings, which incorporate investment-specific assumptions such as discount rates, capitalization rates, rental and expense growth rates, and asset-specific market borrowing rates. We did not consider any adjustments to NAV estimates provided by investees, including adjustments for any restrictions to the transferability of ownership interests embedded within investment agreements to which we are a party, to be necessary based upon (i) our understanding of the methodology utilized and inputs incorporated to estimate NAV at the investee level, (ii) consideration of market demand for the specific types of real estate assets held by each venture and (iii) contemplation of real estate and capital markets conditions in the localities in which these ventures operate. As of June 30, 2024 and December 31, 2023, investments at fair value using NAV were $332.7 million and $321.8 million, respectively. As these investments are not required to be classified in the fair value hierarchy, they have been excluded from the following table. Recurring Fair Value Measurements The following table categorizes by level in the fair value hierarchy the estimated fair value of our assets and liabilities measured at fair value on a recurring basis. June 30, 2024 December 31, 2023 (in millions) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets Investments - fair value $ 44.2 — 367.8 51.7 — 367.3 Foreign currency forward contracts receivable — 1.4 — — 12.5 — Warehouse receivables — 642.4 — — 677.4 — Deferred compensation plan assets — 639.8 — — 604.3 — Mortgage banking derivative assets — — 152.3 — — 128.0 Total assets at fair value $ 44.2 1,283.6 520.1 51.7 1,294.2 495.3 Liabilities Foreign currency forward contracts payable $ — 5.1 — — 8.8 — Deferred compensation plan liabilities — 613.6 — — 576.1 — Earn-out liabilities — — 53.7 — — 57.5 Mortgage banking derivative liabilities — — 120.6 — — 117.7 Total liabilities at fair value $ — 618.7 174.3 — 584.9 175.2 Investments We classify one investment as Level 1 in the fair value hierarchy as a quoted price is readily available. We increase or decrease our investment each reporting period by the change in the fair value of the investment. We report the fair value adjustments in our Consolidated Statements of Comprehensive Income within Equity earnings/losses. Investments classified as Level 3 in the fair value hierarchy represent investments in early-stage non-public entities where we elected the fair value option. For most of our investments, the carrying value was deemed to approximate fair value due to the proximity of the investment date, or date of most recent financing raise, to the balance sheet date, as well as consideration of investee-level performance updates. The fair value of certain investments is estimated using significant unobservable inputs which requires judgment due to the absence of market data. In determining the estimated fair value of these investments, we utilize appropriate valuation techniques including discounted cash flow analyses, scorecard method, Black-Scholes models and other methods as appropriate. Key inputs include projected cash flows, discount rates, peer group multiples and volatility. To the extent there are changes in fair value, we recognize such changes through Equity earnings/losses. Foreign Currency Forward Contracts We regularly use foreign currency forward contracts to manage our currency exchange rate risk related to intercompany lending and cash management practices. These contracts are on the Consolidated Balance Sheets as current assets and current liabilities. We determine the fair values of these contracts based on current market rates. The inputs for these valuations are Level 2 in the fair value hierarchy. The following table details the gross notional value and net basis of these contracts. (in billions) June 30, 2024 December 31, 2023 Foreign currency forward contracts, gross notional value $ 1.90 2.07 Foreign currency forward contracts, net basis 1.21 1.21 We record the asset and liability positions for our foreign currency forward contracts based on the net payable or net receivable position with the financial institutions from which we purchase these contracts. The outstanding balances of these contracts are presented in the following table. (in millions) June 30, 2024 December 31, 2023 Net asset, receivable positions $ 1.4 15.2 Net asset, payable positions — (2.7) Foreign currency forward contracts receivable $ 1.4 12.5 Net liability, receivable positions $ (1.0) (3.2) Net liability, payable positions 6.1 12.0 Foreign currency forward contracts payable $ 5.1 8.8 Warehouse Receivables As of June 30, 2024 and December 31, 2023, all of our Warehouse receivables were under commitment to be purchased by government-sponsored enterprises ("GSEs") or by a qualifying investor as part of a U.S. government or GSE mortgage-backed security program. Deferred Compensation We maintain a deferred compensation plan for certain of our U.S. employees that allows them to defer portions of their compensation. We recorded this plan on our Consolidated Balance Sheet as Deferred compensation plan assets, long-term deferred compensation plan liabilities, included in Deferred compensation, and as a reduction of equity, Shares held in trust. The components of the plan are presented in the following table. (in millions) June 30, 2024 December 31, 2023 Deferred compensation plan assets $ 639.8 604.3 Long-term deferred compensation plan liabilities 613.6 576.1 Shares held in trust 11.9 10.4 Earn-Out Liabilities We classify our Earn-out liabilities within Level 3 in the fair value hierarchy because the inputs we use to develop the estimated fair value include unobservable inputs. See Note 5, Business Combinations, Goodwill and Other Intangible Assets, for additional discussion of our Earn-out liabilities. Mortgage Banking Derivatives Both our interest rate lock commitments to prospective borrowers and forward sale contracts with prospective investors are undesignated derivatives and considered Level 3 valuations due to significant unobservable inputs related to nonperformance risk. An increase in nonperformance risk assumptions would result in a lower fair value measurement. The tables below present a reconciliation for assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3).

Category of Assets/Liabilities using Unobservable Inputs Consolidated Statements Earn-out liabilities (short-term and long-term) Restructuring and acquisition charges Investments Equity earnings/losses Other current assets - Mortgage banking derivative assets Revenue Other current liabilities - Mortgage banking derivative liabilities Revenue Non-Recurring Fair Value Measurements We review our investments, except those investments otherwise reported at fair value, on a quarterly basis, or as otherwise deemed necessary, for indications of whether we may be unable to recover the carrying value of our investments and whether such investments are other than temporarily impaired. When the carrying amount of the investment is in excess of the estimated future undiscounted cash flows, we use a discounted cash flow approach or other acceptable method to determine the fair value of the investment in computing the amount of the impairment. Our determination of fair value primarily relies on Level 3 inputs. We did not recognize any significant investment-level impairment losses during either of the six months ended June 30, 2024 or 2023. See Note 6, Investments, for additional information, including information related to impairment charges recorded at the investee level.

Pricing on the Facility ranges from Adjusted Term Secured Overnight Financing Rate ("SOFR") plus 0.875% to 1.35%, with pricing including facility fees, as of June 30, 2024 at Adjusted Term SOFR plus 0.98%. In addition to outstanding borrowings under the Facility presented in the above table, we had outstanding letters of credit under the Facility of $0.4 million as of both June 30, 2024 and December 31, 2023. In addition, we have an uncommitted credit agreement (the "Uncommitted Facility"), which allows for discretionary short-term liquidity of up to $400.0 million. Interest and fees are set at the time of utilization and calculated on a 360-day basis. Between quarter-end dates, we intend to use the proceeds to reduce indebtedness under the Facility at a lower interest rate. As such, the Uncommitted Facility had no outstanding balance as of both June 30, 2024 and December 31, 2023. The following table provides additional information on our Facility and Uncommitted Facility, collectively.

Short-Term and Long-Term Debt In addition to our credit facilities, we have the capacity to borrow up to an additional $53.8 million under local overdraft facilities. Amounts outstanding are presented in the debt table above. As of June 30, 2024, our issuer and senior unsecured ratings are investment grade: Baa1 from Moody’s Investors Service, Inc. and BBB+ from Standard & Poor’s Ratings Services. Commercial Paper Program On June 27, 2024, we established a commercial paper program (the “Program”) in which we may issue up to $2.5 billion of short-term, unsecured and unsubordinated commercial paper notes at any time, under the exemption from registration contained in Section 4(a)(2) of the Securities Act of 1933, as amended. Amounts available under the Program may be borrowed, repaid and re-borrowed from time to time. Payment of the Program notes will be fully and unconditionally guaranteed on an unsecured and unsubordinated basis. We intend to use net proceeds of the Program for general corporate purposes, including the repayment of outstanding borrowings under the Facility. Notes issued under the Program will be sold under customary market terms in the U.S. commercial paper market at par less a discount representing an interest factor or, if interest bearing, at par. The maturities of the Program notes may vary but may not exceed 397 days from the date of issuance. The Program notes and guarantee of payment thereof will rank pari passu with all other unsecured and unsubordinated indebtedness. As of the end of June 30, 2024, we have not issued any notes under the Program. Covenants Our Facility and senior notes are subject to customary financial and other covenants, including cash interest coverage ratios and leverage ratios, as well as event of default conditions.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	COMMITMENTS AND CONTINGENCIES We are a defendant in various litigation matters arising in the ordinary course of business, some of which involve claims for damages that are substantial in amount. Professional Indemnity Insurance In order to better manage our global insurance program and support our risk management efforts, we supplement our traditional insurance coverage for certain types of claims by using a wholly-owned captive insurance company. The level of risk retained by our captive insurance company, with respect to professional indemnity claims, is up to $9.0 million per claim. We contract third-party insurance companies to provide coverage of risk in excess of this amount. When a potential loss event occurs, we estimate the ultimate cost of the claim and accrue the amount in Other current and long-term liabilities on our Consolidated Balance Sheets when probable and estimable. In addition, we have established receivables from third-party insurance providers for claim amounts in excess of the risk retained by our captive insurance company. There was no such receivable recorded as of June 30, 2024. As of December 31, 2023, a receivable of $2.5 million was included in Notes and other receivables on our Consolidated Balance Sheet. The following table shows the professional indemnity accrual activity and related payments. (in millions) December 31, 2023 $ 9.4 New claims 0.2 Prior year claims adjustments (including foreign currency changes) 0.4 Claims paid (7.2) June 30, 2024 $ 2.8 December 31, 2022 $ 2.2 New claims 0.3 Prior year claims adjustments (including foreign currency changes) 4.4 Claims paid — June 30, 2023 $ 6.9 Delegated Underwriting and Servicing ("DUS") Program Loan Loss-Sharing As a participant in the DUS program, we retain a portion of the risk of loss for loans that are originated and sold under the DUS program. Net losses on defaulted loans are shared with Fannie Mae based upon established loss-sharing ratios. Generally, we share approximately one-third of incurred losses, subject to a cap of 20% of the principal balance of the mortgage at origination. As of June 30, 2024 and December 31, 2023, we had loans, funded and sold, subject to such loss-sharing arrangements with an aggregate unpaid principal balance of $21.8 billion and $20.8 billion, respectively. For all DUS program loans with loss-sharing obligations, we record a non-contingent liability equal to the estimated fair value of the guarantee obligations undertaken upon sale of the loan, which reduces our gain on sale of the loan. Subsequently, this liability is amortized over the estimated life of the loan and recognized as Revenue on the Consolidated Statements of Comprehensive Income. As of June 30, 2024 and December 31, 2023, the loss-sharing guarantee obligations were $30.6 million and $30.9 million, respectively, and are included in Other liabilities on our Consolidated Balance Sheets. There were no loan losses incurred during the six months ended June 30, 2024 and 2023. The loss-sharing aspect of the program represents an off-balance sheet credit exposure. We record a separate contingent reserve for this risk calculated on an individual loan level. As of June 30, 2024 and December 31, 2023, the loan loss guarantee reserve was $26.4 million and $23.4 million, respectively, and is included within Other liabilities on our Consolidated Balance Sheets.

Subsequent Events & New Accounting Standards	SUBSEQUENT EVENTS & NEW ACCOUNTING STANDARDS Subsequent events In August of 2024, we repurchased a loan, which we originated and sold to Fannie Mae, with an unpaid principal balance ("UPB") of $74.25 million. As this subsequent event represented additional evidence about a matter that existed as of the reporting date, for the period ended June 30, 2024, we recognized $18.0 million within Operating, administrative and other expenses, for the current estimated loss associated with the repurchase in our results. This impact represents the difference between our estimate of the current fair value of the repurchased loan and the repurchase price, including amounts in excess of the UPB for items such as unpaid interest. Recently issued accounting guidance In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures , which requires a public entity to disclose significant segment expenses and other segment items on an annual and interim basis and to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. The FASB issued the ASU in response to requests from investors for companies to disclose more information about their financial performance at the segment level. The ASU does not change how a public entity identifies its operating segments, aggregates them, or applies the quantitative thresholds to determine its reportable segments. This ASU is effective for annual periods beginning after December 15, 2023, and for interim periods beginning after December 15, 2024, with early adoption permitted. We are evaluating the effect this guidance will have on our segment disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures , which enhances the income tax disclosures to provide information to better assess how an entity’s operations and related tax risks and tax planning and operational opportunities affect its tax rate and prospects for future cash flows. This ASU is effective for annual periods beginning after December 15, 2024, with early adoption permitted. We are evaluating the effect this guidance will have on our tax disclosures.
