Significant Accounting Policies [Text Block]	2. Summary of presentation The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The most significant estimates are related to the judgments used to determine the timing and amount of revenue recognition, recoverability of goodwill and intangible assets, determination of fair values of assets acquired and liabilities assumed in business combinations, estimated fair value of contingent consideration related to acquisitions, determination of the fair value of capitalized mortgage servicing rights and derivative financial instruments, and current expected credit losses on financial assets including collectability of accounts receivable and allowance for loss sharing obligations. Actual results could be materially different from these estimates. In the third 2024, Significant accounting policies are summarized as follows: Principles of consolidation The accompanying consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and those variable interest entities where the Company is the primary beneficiary. Where the Company does not When applying the principles of consolidation, the Company begins by determining whether an investee is a variable interest entity (“VIE”) or a voting interest entity (“VOE”). Assessing whether an entity is a VIE or a VOE involves judgment and analysis. Factors considered in this assessment include the entity’s legal organization, the entity’s capital structure and equity ownership, and any related party or de facto agent implications of the Company’s involvement with the entity. VOEs are embodied by common and traditional corporate and certain partnership structures. For VOEs, the interest holder with control through majority ownership and majority voting rights consolidates the entity. For VIEs, identification of the primary beneficiary determines the accounting treatment. In evaluating whether the Company is the primary beneficiary, it evaluates its direct and indirect economic interests in the entity. A reporting entity is determined to be the primary beneficiary if it holds a controlling financial interest in the VIE. Determining which reporting entity, if any, has a controlling financial interest in a VIE is primarily a qualitative approach focused on identifying which reporting entity has both ( 1 2 The primary beneficiary analysis is performed at the inception of the Company’s investment and upon the occurrence of a reconsideration event. When the Company determines it is the primary beneficiary of a VIE, it consolidates the VIE; when it is determined that the Company is not Cash and cash equivalents The Company maintains custodial escrow accounts, agency and fiduciary funds relating to its debt finance operations and as an agent for its property management operations. These amounts are not not Restricted cash Restricted cash consists primarily of cash and cash equivalent amounts set aside to satisfy legal or contractual requirements arising in the normal course of business, primarily at Colliers Mortgage. Receivables and allowance for credit losses Accounts receivables are recorded when the Company has a right to payment within customary payment terms or it recognizes a contract asset if revenue is recognized prior to when payment is due. From the point of initial recognition, the carrying value of such receivables and contract assets, net of allowance for credit losses, represents their estimated net realizable value after deducting for potential credit losses. The Company’s expected loss allowance methodology uses historical collection experience, the current status of customers’ accounts receivable and considers both current and expected future economic and market conditions. Due to the short-term nature of such receivables, the estimate of accounts receivable that may not In some cases, the Company may Fixed assets Fixed assets are carried at cost less accumulated depreciation. The costs of additions and improvements are capitalized, while maintenance and repairs are expensed as incurred. Fixed assets are reviewed for impairment whenever events or circumstances indicate that the carrying value of an asset group may not Buildings 20 to 40 years straight-line Vehicles 3 to 5 years straight-line Furniture and equipment 3 to 10 years straight-line Computer equipment and software 3 to 7 years straight-line Leasehold improvements 1 to 10 years straight-line (based upon term of the lease) Investments Equity accounted investments For equity investments where it does not not may may The Company’s equity accounted investees that are investment companies record their underlying investments at fair value. Therefore, under the equity method of accounting, the Company’s share of the investee’s underlying net income predominantly represents fair value adjustments in the investments held by the equity method investees. The Company’s share of the investee’s underlying net income or loss is based upon the most currently available information, which may Investments in debt and equity securities The Company invests in debt and equity securities primarily in relation to its wholly owned captive insurance company and Colliers Securities, a broker-dealer licensed under the Securities and Exchange Commission and a member of the Financial Industry Regulatory Authority (“FINRA”). These investments are accounted for at fair value with changes recorded in net earnings (loss). Financial instruments and derivatives Certain loan commitments and forward sales commitments related to the Company’s warehouse receivables meet the definition of a derivative and are recorded at fair value in the consolidated balance sheets upon the execution of the commitment to originate a loan with a borrower and to sell the loan to an investor, with a corresponding amount recognized as revenue in the consolidated statements of earnings. The estimated fair value of loan commitments includes the value of loan origination fees and premiums on anticipated sale of the loan, net of related costs and broker fees, a loss sharing reserve, the fair value of the expected net cash flows associated with servicing of the loan, and the effects of interest rate movements. The estimated fair value of the forward sales commitments includes the effects of interest rate movements. Adjustments to the fair value related to loan commitments and forward sale commitments are included within Capital Markets revenue in the Real Estate Services segment. (See note 25 From time to time, the Company uses interest rate swaps to hedge a portion of its interest rate exposure on long-term debt. When hedge accounting is applied, the swaps are carried at fair value on the consolidated balance sheets, with gains or losses recognized in interest expense. The carrying value of the hedged item is adjusted for changes in fair value attributable to the hedged interest rate risk; the associated gain or loss is recognized currently in earnings and the unrealized gain or loss is recognized in other comprehensive income. If swaps are terminated and the underlying item is not may Derivative financial instruments are recorded on the consolidated balance sheets as other assets or other liabilities and carried at fair value. See note 22 Fair value The Company uses the fair value measurement framework for financial assets and liabilities and for non-financial assets and liabilities that are recognized or disclosed at fair value on a non-recurring basis. The framework defines fair value, gives guidance for measurement and disclosure, and establishes a three three Level 1 Level 2 Level 3 no Convertible notes Convertible Notes are accounted for entirely as debt as no The earnings per share impact of the Convertible Notes is calculated using the “if-converted” method, if dilutive, where coupon interest expense, net of tax, is added to the numerator and the number of potentially issuable subordinate voting shares is added to the denominator. Convertible Notes were fully settled in June 2023. Financing fees Financing fees related to the Revolving Credit Facility are recorded as an asset and amortized to interest expense using the effective interest method. Financing fees related to the Senior Notes and Convertible Notes are recorded as a reduction of the debt amount and are amortized to interest expense using the effective interest method. Financial guarantees and allowance for loss sharing obligations For certain loans originated and sold under the Fannie Mae Delegated Underwriting and Servicing (“DUS”) Program the Company undertakes an obligation to partially guarantee performance of the loan typically up to one third When the Company commits to making a loan to a borrower, it recognizes an expense equal to the estimated fair value of this loss sharing obligation (the “Loss Reserve”), which reduces the gain on sale of the loan reported in Capital Markets revenue. In accordance with ASC 326, 23 Warehouse receivables The Company originates held for sale mortgage loans with commitments to sell to third 45 Warehouse fund assets From time to time, the Company’s Investment Management segment purchases investments for placement, or “seeding”, of assets into a fund which it manages. The purchased investments are recorded at fair value as warehouse fund assets and corresponding liabilities related to warehouse fund assets prior to the ultimate divestiture to the identified fund. These assets and associated liabilities may may not twelve The transactions are not not 5 Mortgage servicing rights ( MSRs ) MSRs, or the rights to service mortgage loans for others, result from the sale or securitization of loans originated by the Company and are recognized as intangible assets on the consolidated balance sheets. The Company initially recognizes MSRs based on the fair value of these rights on the date the loans are sold. Subsequent to initial recognition, MSRs are amortized and carried at the lower of amortized cost or fair value. They are amortized in proportion to and over the estimated period that net servicing income is expected to be received based on projections and timing of estimated future net cash flows. In connection with the origination and sale of mortgage loans for which the Company retains servicing rights, an asset or liability is recognized based upon the fair value of the MSR on the date that the loans are sold. Upon origination of a mortgage loan held for sale, the fair value of the retained MSR is included in the forecasted proceeds from the anticipated loan sale and results in a net gain (which is reflected in Capital Markets revenue).

Redeemable non-controlling interests Redeemable non-controlling interests (“RNCI”) are recorded at the greater of (i) the redemption amount or (ii) the amount initially recorded as RNCI at the date of inception of the minority equity position. This amount is recorded in the “mezzanine” section of the balance sheet, outside of shareholders’ equity. Changes in the RNCI amount are recognized immediately as they occur. Revenue The Company generates revenue through its provision of commercial real estate services and investment management. These services consist of Leasing, Capital Markets, Outsourcing, Engineering and Investment Management services. (a) Leasing Leasing includes landlord and tenant representation services. Landlord representation provides real estate owners with services to strategically position properties and to secure appropriate tenants. Tenant representation focuses on assisting businesses to assess their occupancy requirements and evaluating and negotiating leases and lease renewals. (b) Capital Markets Capital Markets revenue is generated through sales brokerage and other capital markets transactions. These services include real estate sales, debt origination and placement, equity capital raising, market value opinions, acquisition advisory and transaction management. The Company’s debt finance operations relate to the origination and sale of multifamily and commercial mortgage loans. (c) Outsourcing Outsourcing services consist of valuation services, property management, loan servicing and other revenues.

Financial Instruments Disclosure [Text Block]	22. Financial instruments Concentration of credit risk The Company is subject to credit risk with respect to its cash and cash equivalents, accounts receivable, contract assets, other receivables and advisor loans receivable. Concentrations of credit risk with respect to cash and cash equivalents are limited by the use of multiple large and reputable banks. Concentrations of credit risk with respect to receivables are limited due to the large number of entities comprising the Company’s customer base and other counterparties, and their dispersion across different service lines in various countries. Foreign currency risk Foreign currency risk is related to the portion of the Company’s business transactions denominated in currencies other than US dollars. A significant portion of revenue is generated by the Company’s Canadian, Australian, UK and Euro currency operations. The Company’s head office expenses are incurred primarily in Canadian dollars which are hedged by Canadian dollar denominated revenue. Fluctuations in foreign currencies impact the amount of total assets and liabilities that are reported for foreign subsidiaries upon the translation of these amounts into US dollars. In particular, the amount of cash, working capital, goodwill and intangibles held by these subsidiaries is subject to translation variance caused by changes in foreign currency exchange rates as of the end of each respective reporting period (the offset to which is recorded to accumulated other comprehensive income on the consolidated balance sheets). Interest rate risk The Company utilizes an interest rate risk management strategy that may Fair values of financial instruments The following table provides the financial assets and liabilities carried at fair value measured on a recurring basis as of December 31, 2024: Level 1 Level 2 Level 3 Assets Equity securities $ 13,088 $ 9 $ - Debt securities 14,166 22,399 - Mortgage derivative assets - - 5,264 Mortgage warehouse receivables - 77,559 - Interest rate swap assets - 7,870 - Deferred Purchase Price on AR Facility - - 126,082 Total assets $ 27,254 $ 107,837 $ 131,346 Liabilities Mortgage derivative liabilities $ - $ - $ 1,935 Interest rate swap liabilities - 268 - Contingent consideration liabilities - - 36,695 Total liabilities $ - $ 268 $ 38,630 Equity securities, debt securities, mortgage derivative assets, interest rate swap assets and the deferred purchase price on the AR Facility were included in prepaid expenses and other current assets on the consolidated balance sheets.

In the case of interest rate lock commitments, the fair value measurement also considers the expected net cash flows associated with the servicing of the loans. The Company also considers the impact of unobservable inputs related to counterparty non-performance risk when measuring the fair value of these derivatives. Therefore, these mortgage-related derivatives are categorized as Level 3.

The DPP represents the difference between the fair value of the Receivables sold and the cash purchase price and is recognized at fair value as part of the sale transaction. The DPP is remeasured each reporting period in order to account for activity during the period, including the seller’s interest in any newly transferred Receivables, collections on previously transferred Receivables attributable to the DPP and changes in estimates for credit losses. Changes in the DPP attributed to changes in estimates for credit losses are expected to be immaterial, as the underlying Receivables are short-term and of high credit quality.

Accounting Policies [Abstract]
Basis of Accounting, Policy [Policy Text Block]	The preparation of consolidated financial statements in accordance with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. The most significant estimates are related to the judgments used to determine the timing and amount of revenue recognition, recoverability of goodwill and intangible assets, determination of fair values of assets acquired and liabilities assumed in business combinations, estimated fair value of contingent consideration related to acquisitions, determination of the fair value of capitalized mortgage servicing rights and derivative financial instruments, and current expected credit losses on financial assets including collectability of accounts receivable and allowance for loss sharing obligations. Actual results could be materially different from these estimates. In the third 2024, Significant accounting policies are summarized as follows:
Consolidation, Policy [Policy Text Block]	Principles of consolidation The accompanying consolidated financial statements include the accounts of the Company, its majority-owned subsidiaries and those variable interest entities where the Company is the primary beneficiary. Where the Company does not When applying the principles of consolidation, the Company begins by determining whether an investee is a variable interest entity (“VIE”) or a voting interest entity (“VOE”). Assessing whether an entity is a VIE or a VOE involves judgment and analysis. Factors considered in this assessment include the entity’s legal organization, the entity’s capital structure and equity ownership, and any related party or de facto agent implications of the Company’s involvement with the entity. VOEs are embodied by common and traditional corporate and certain partnership structures. For VOEs, the interest holder with control through majority ownership and majority voting rights consolidates the entity. For VIEs, identification of the primary beneficiary determines the accounting treatment. In evaluating whether the Company is the primary beneficiary, it evaluates its direct and indirect economic interests in the entity. A reporting entity is determined to be the primary beneficiary if it holds a controlling financial interest in the VIE. Determining which reporting entity, if any, has a controlling financial interest in a VIE is primarily a qualitative approach focused on identifying which reporting entity has both ( 1 2 The primary beneficiary analysis is performed at the inception of the Company’s investment and upon the occurrence of a reconsideration event. When the Company determines it is the primary beneficiary of a VIE, it consolidates the VIE; when it is determined that the Company is not
Cash and Cash Equivalents, Policy [Policy Text Block]	Cash and cash equivalents The Company maintains custodial escrow accounts, agency and fiduciary funds relating to its debt finance operations and as an agent for its property management operations. These amounts are not not
Cash and Cash Equivalents, Restricted Cash and Cash Equivalents, Policy [Policy Text Block]	Restricted cash Restricted cash consists primarily of cash and cash equivalent amounts set aside to satisfy legal or contractual requirements arising in the normal course of business, primarily at Colliers Mortgage.
Receivable [Policy Text Block]	Receivables and allowance for credit losses Accounts receivables are recorded when the Company has a right to payment within customary payment terms or it recognizes a contract asset if revenue is recognized prior to when payment is due. From the point of initial recognition, the carrying value of such receivables and contract assets, net of allowance for credit losses, represents their estimated net realizable value after deducting for potential credit losses. The Company’s expected loss allowance methodology uses historical collection experience, the current status of customers’ accounts receivable and considers both current and expected future economic and market conditions. Due to the short-term nature of such receivables, the estimate of accounts receivable that may not In some cases, the Company may
Property, Plant and Equipment, Policy [Policy Text Block]	Fixed assets Fixed assets are carried at cost less accumulated depreciation. The costs of additions and improvements are capitalized, while maintenance and repairs are expensed as incurred. Fixed assets are reviewed for impairment whenever events or circumstances indicate that the carrying value of an asset group may not Buildings 20 to 40 years straight-line Vehicles 3 to 5 years straight-line Furniture and equipment 3 to 10 years straight-line Computer equipment and software 3 to 7 years straight-line Leasehold improvements 1 to 10 years straight-line (based upon term of the lease)
Investment, Policy [Policy Text Block]	Investments Equity accounted investments For equity investments where it does not not may may The Company’s equity accounted investees that are investment companies record their underlying investments at fair value. Therefore, under the equity method of accounting, the Company’s share of the investee’s underlying net income predominantly represents fair value adjustments in the investments held by the equity method investees. The Company’s share of the investee’s underlying net income or loss is based upon the most currently available information, which may Investments in debt and equity securities The Company invests in debt and equity securities primarily in relation to its wholly owned captive insurance company and Colliers Securities, a broker-dealer licensed under the Securities and Exchange Commission and a member of the Financial Industry Regulatory Authority (“FINRA”). These investments are accounted for at fair value with changes recorded in net earnings (loss).
Derivatives, Policy [Policy Text Block]	Financial instruments and derivatives Certain loan commitments and forward sales commitments related to the Company’s warehouse receivables meet the definition of a derivative and are recorded at fair value in the consolidated balance sheets upon the execution of the commitment to originate a loan with a borrower and to sell the loan to an investor, with a corresponding amount recognized as revenue in the consolidated statements of earnings. The estimated fair value of loan commitments includes the value of loan origination fees and premiums on anticipated sale of the loan, net of related costs and broker fees, a loss sharing reserve, the fair value of the expected net cash flows associated with servicing of the loan, and the effects of interest rate movements. The estimated fair value of the forward sales commitments includes the effects of interest rate movements. Adjustments to the fair value related to loan commitments and forward sale commitments are included within Capital Markets revenue in the Real Estate Services segment. (See note 25 From time to time, the Company uses interest rate swaps to hedge a portion of its interest rate exposure on long-term debt. When hedge accounting is applied, the swaps are carried at fair value on the consolidated balance sheets, with gains or losses recognized in interest expense. The carrying value of the hedged item is adjusted for changes in fair value attributable to the hedged interest rate risk; the associated gain or loss is recognized currently in earnings and the unrealized gain or loss is recognized in other comprehensive income. If swaps are terminated and the underlying item is not may Derivative financial instruments are recorded on the consolidated balance sheets as other assets or other liabilities and carried at fair value. See note 22
Fair Value Measurement, Policy [Policy Text Block]	Fair value The Company uses the fair value measurement framework for financial assets and liabilities and for non-financial assets and liabilities that are recognized or disclosed at fair value on a non-recurring basis. The framework defines fair value, gives guidance for measurement and disclosure, and establishes a three three Level 1 Level 2 Level 3 no
Convertible Notes [Policy Text Block]	Convertible notes Convertible Notes are accounted for entirely as debt as no The earnings per share impact of the Convertible Notes is calculated using the “if-converted” method, if dilutive, where coupon interest expense, net of tax, is added to the numerator and the number of potentially issuable subordinate voting shares is added to the denominator. Convertible Notes were fully settled in June 2023.
Deferred Charges, Policy [Policy Text Block]	Financing fees Financing fees related to the Revolving Credit Facility are recorded as an asset and amortized to interest expense using the effective interest method. Financing fees related to the Senior Notes and Convertible Notes are recorded as a reduction of the debt amount and are amortized to interest expense using the effective interest method.
Guarantees, Indemnifications and Warranties Policies [Policy Text Block]	Financial guarantees and allowance for loss sharing obligations For certain loans originated and sold under the Fannie Mae Delegated Underwriting and Servicing (“DUS”) Program the Company undertakes an obligation to partially guarantee performance of the loan typically up to one third When the Company commits to making a loan to a borrower, it recognizes an expense equal to the estimated fair value of this loss sharing obligation (the “Loss Reserve”), which reduces the gain on sale of the loan reported in Capital Markets revenue. In accordance with ASC 326, 23
Financing Receivable, Held-for-Sale [Policy Text Block]	Warehouse receivables The Company originates held for sale mortgage loans with commitments to sell to third 45
Real Estate Held for Development and Sale, Policy [Policy Text Block]	Warehouse fund assets From time to time, the Company’s Investment Management segment purchases investments for placement, or “seeding”, of assets into a fund which it manages. The purchased investments are recorded at fair value as warehouse fund assets and corresponding liabilities related to warehouse fund assets prior to the ultimate divestiture to the identified fund. These assets and associated liabilities may may not twelve The transactions are not not 5
Transfers and Servicing of Financial Assets, Servicing of Financial Assets, Policy [Policy Text Block]	Mortgage servicing rights ( MSRs ) MSRs, or the rights to service mortgage loans for others, result from the sale or securitization of loans originated by the Company and are recognized as intangible assets on the consolidated balance sheets. The Company initially recognizes MSRs based on the fair value of these rights on the date the loans are sold. Subsequent to initial recognition, MSRs are amortized and carried at the lower of amortized cost or fair value. They are amortized in proportion to and over the estimated period that net servicing income is expected to be received based on projections and timing of estimated future net cash flows. In connection with the origination and sale of mortgage loans for which the Company retains servicing rights, an asset or liability is recognized based upon the fair value of the MSR on the date that the loans are sold. Upon origination of a mortgage loan held for sale, the fair value of the retained MSR is included in the forecasted proceeds from the anticipated loan sale and results in a net gain (which is reflected in Capital Markets revenue). MSRs do not December 31, 2024 December 31, 2023, As at December 31, 2024 2023 Discount rate 12.1 % 11.7 % Conditional prepayment rate 3.7 % 3.1 % As at December 31, 2024, 2023 10
Goodwill and Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill and intangible assets Goodwill represents the excess of purchase price over the fair value of assets acquired and liabilities assumed in a business combination and is not Intangible assets are recorded at fair value on the date they are acquired. Indefinite life intangible assets are not Customer lists and relationships straight-line over 4 to 20 years Investment management contracts straight-line over 5 to 15 years Trademarks and trade names straight-line over 2 to 10 years Franchise rights straight-line over 2 to 15 years Management contracts and other straight-line over life of contract ranging from 2 to 10 years Backlog as underlying backlog transactions are completed The Company reviews the carrying value of finite life intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset group may not Following the change in segment structure in the current year, the Company reassessed its reporting units and concluded that there are three distinct reporting units. Goodwill and indefinite life intangible assets are tested for impairment annually, on August 1, two one one Impairment of goodwill is tested at the reporting unit level. Impairment is tested by first not not no not 3 Impairment of indefinite life intangible assets is tested by comparing the carrying amount to the estimated fair value on an individual intangible asset basis.
Consolidation, Subsidiaries or Other Investments, Consolidated Entities, Policy [Policy Text Block]	Redeemable non-controlling interests Redeemable non-controlling interests (“RNCI”) are recorded at the greater of (i) the redemption amount or (ii) the amount initially recorded as RNCI at the date of inception of the minority equity position. This amount is recorded in the “mezzanine” section of the balance sheet, outside of shareholders’ equity. Changes in the RNCI amount are recognized immediately as they occur.
Revenue [Policy Text Block]	Revenue The Company generates revenue through its provision of commercial real estate services and investment management. These services consist of Leasing, Capital Markets, Outsourcing, Engineering and Investment Management services. (a) Leasing Leasing includes landlord and tenant representation services. Landlord representation provides real estate owners with services to strategically position properties and to secure appropriate tenants.

The Company enters into contracts that can include various combinations of services, which are capable of being distinct and accounted for as separate performance obligations. Revenue is recognized net of any taxes collected from customers, which are subsequently remitted to governmental authorities. (a) Nature of services The Company has determined that control of real estate sales brokerage services rendered transfer to a customer when a sale and purchase agreement becomes unconditional. Leasing services rendered transfer to a customer when a lease between the landlord and the tenant is executed. At these points in time the customer has received substantially all of the benefit of the services provided by the Company. The transaction price is typically associated with the underlying asset involved in the transaction, most commonly a percentage of the sales price or the aggregate rental payments over the term of the lease which are generally known when revenue is recognized. Other Capital Market revenues are recorded when the Company’s performance obligation is satisfied. Although the performance obligation varies based upon the contractual terms of the transaction or service, the performance obligation is generally recognized at the point in time when a defined outcome is satisfied, including completion of financing or closing of a transaction.

For some projects certain obligations that are representative of the work completed may For other advisory services, including valuation and appraisal review, the customer is unable to benefit from the services until the work is substantially complete, revenue is recognized upon delivery of deliverables to the customer because this faithfully represents when the service has been rendered. For most fixed fee consulting assignments, revenue is recognized based upon the actual service provided to the end of the reporting period as a proportion of the total services to be provided. Loan servicing revenues are recognized over the contractual service period. Loan servicing fees related to retained MSRs are governed by ASC 820 860 606. not 606. Investment Management advisory fees are recognized as the services are performed over time and are primarily based on agreed-upon percentages of a calculated fee base which may no (b) Significant judgments The Company’s contracts with customers may may not Brokerage commission arrangements may may may not not Outsourcing and Engineering arrangements may For project management, engineering and design within Engineering or property management services forming part of Outsourcing, the Company may not In some cases, the Company may may Investment Management fee arrangements are unique to each contract and evaluated on an individual basis to determine the timing of revenue recognition as well as evaluation of incentive-fee related compensation expense and significant judgment is involved in making such determinations. At each reporting period, the Company considers various factors in estimating revenue to be recognized and incentive fee related-compensation expense to be accrued. Incentive fees have a broad range of possible amounts and the determination of these amounts is based upon the market value for managed assets which is highly susceptible to factors outside of the Company’s influence. As a result, incentive fee revenue is generally constrained until significant reversal is considered no Certain constrained Capital Markets and Leasing fees, Outsourcing fees, Engineering fees and Investment Management fees may may Contract balances Timing of revenue recognition may may not one not The Company generally does not one one Payment terms and conditions vary by contract type, although terms generally include a requirement of payment within 30 90 not one may not one not not Contract liabilities represent advance payments associated with the Company’s performance obligations that have not Remaining performance obligations Remaining performance obligations represent the aggregate transaction prices for contracts where the Company’s performance obligations have not one
Share-Based Payment Arrangement [Policy Text Block]	Stock based compensation For equity classified awards, compensation cost is measured at the grant date based on the estimated fair value of the award adjusted for expected forfeitures. For liability classified awards, costs are measured at the grant date based on the estimated fair value of the award. The liability is remeasured at the end of each reporting period. The liability is recorded in accrued compensation or non-current liabilities. The related stock-based compensation expenses are allocated using the graded attribution method and reported as selling, general & administrative expenses.
