Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Information	1. 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" or as "we," "us" or "our") for the year ended December 31, 2018 , which are included in our 2018 Annual Report on Form 10-K, filed with the United States Securities and Exchange Commission ("SEC") and also available on our website ( www.us.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 Result of Operations and to Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements in our 2018 Annual Report on Form 10-K for further discussion of our significant accounting policies and estimates. Our Condensed Consolidated Financial Statements as of March 31, 2019 , and for the three months ended March 31, 2019 and 2018 , 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 Condensed Consolidated Financial Statements for these interim periods. We have reclassified certain prior-year amounts to conform to the current year 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. 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. Within our Real Estate Services ("RES") segments, revenue from capital markets activities is driven by the size and timing of our clients' transactions and can fluctuate significantly from period to period. 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 March 31, 2019 and 2018

New Accounting Standards	2. NEW ACCOUNTING STANDARDS Recently adopted accounting guidance In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which increases transparency and comparability by requiring the recognition of lease assets and lease liabilities on the balance sheet, as well as requiring the disclosure of key information about leasing arrangements. On January 1, 2019, we adopted ASU No. 2016-02, Leases (ASC Topic 842) , on a modified retrospective basis under the optional transition method. Therefore, the application of the provisions of this ASU are effective January 1, 2019, and comparative periods are presented in accordance with ASC Topic 840. Additionally, we elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed us to carry forward (1) our historical lease classification and assessments for expired and existing leases, and (2) our historical accounting for initial direct costs for existing leases. We elected not to record on the Condensed Consolidated Balance Sheets any lease whose term is 12 months or less and does not include a purchase option that we are reasonably certain to exercise. We also elected to account for the non-lease components within our leases as part of the single lease component to which they are related. The most significant impact of the adoption of this ASU was an increase to the Condensed Consolidated Balance Sheets to reflect operating lease right-of-use assets and lease liabilities, which are primarily associated with our office leases around the world. Our accounting for finance leases was not materially impacted. See Note 9, Leases , for additional information on the impact of ASC 842 adoption. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment , which eliminates Step 2 from the goodwill impairment test. The annual goodwill impairment test will require companies to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge when the carrying amount exceeds the fair value of the reporting unit. This ASU is effective for annual and interim goodwill impairment tests beginning after December 15, 2019, with early adoption permitted. We adopted this guidance effective January 1, 2019, and, as a result, will no longer apply Step 2 when performing the goodwill impairment test. This guidance had no material impact on our financial statements and related disclosures. Recently issued accounting guidance, no t yet adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) , which creates a new framework to evaluate financial instruments, such as trade receivables, for expected credit losses. This new framework replaces the existing incurred loss approach and is expected to result in more timely recognition of credit losses. ASU No. 2016-13 is effective for annual and interim periods beginning after December 15, 2019. We are currently evaluating the effect this guidance will have on our financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract

Revenue from Contract with Customer [Text Block]	3. REVENUE RECOGNITION Revenue excluded from the scope of ASC Topic 606 - Our mortgage banking and servicing operations - such as MSR-related activity, loan origination fees, and servicing income - are excluded from the scope of ASC Topic 606. For the three months ended March 31, 2019 and 2018 , such revenue was $31.0 million and $31.2 million , respectively, and was included entirely within Americas Capital Markets. Contract assets - As of March 31, 2019 and December 31, 2018 , we had $387.7 million and $396.2 million of contract assets, respectively, which are included in Short-term contract assets and Other assets on the Condensed Consolidated Balance Sheets. Contract liabilities - As of March 31, 2019 and December 31, 2018 , we had $91.1 million and $98.9 million of contract liabilities, respectively, which are included in Short-term contract liabilities and deferred income on our Condensed Consolidated Balance Sheets. The majority of contract liabilities are recognized as revenue within 90 days. Remaining performance obligations - Remaining performance obligations represent the aggregate transaction price for contracts where our performance obligations have not yet been satisfied. As of March 31, 2019 , the aggregate amount of transaction price allocated to remaining performance obligations represented approximately 5%

Business Segments

Segment Reporting [Abstract]
Business Segments	4. BUSINESS SEGMENTS We manage and report our operations as four business segments: The three geographic regions of RES including: (1) Americas, (2) Europe, Middle East and Africa ("EMEA"), and (3) Asia Pacific; and (4) LaSalle, which offers investment management services on a global basis. Each geographic region offers our full range of real estate services, including agency leasing and tenant representation, capital markets, property and facility management, project and development management, energy management and sustainability, construction management, and advisory, consulting and valuation services. LaSalle provides investment management services to institutional investors and high-net-worth individuals. Operating income represents total revenue less direct and allocated indirect expenses. 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 global overhead, which we allocate to the business segments based on the budgeted operating expenses of each segment. For segment reporting, (a) gross contract costs and (b) net non-cash mortgage servicing rights ("MSR") and mortgage banking derivative activity are both excluded from revenue in determining "fee revenue". Gross contract costs are excluded from operating expenses in determining "fee-based operating expenses." Excluding these costs from revenue and expenses results in a net presentation which we believe more accurately reflects how we manage our expense base, operating margins, and performance. Refer to Results of Operations, included in Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations, for a full description of gross contract costs. In addition, our measure of segment results excludes Restructuring and acquisition charges. The Chief Operating Decision Maker of JLL measures and evaluates the segment results excluding (a) gross contract costs, (b) net non-cash MSR and mortgage banking derivative activity, and (c) Restructuring and acquisition charges. As of March 31, 2019 , we define the Chief Operating Decision Maker collectively as our Global Executive Board, which comprises the following: • Global Chief Executive Officer • Chief Executive Officers of each of our four business segments • Global Chief Financial Officer • Global Chief Executive Officer of Corporate Solutions • Global Chief Administrative Officer • Global Chief Executive Officer of Capital Markets Summarized financial information by business segment is as follows.

BUSINESS COMBINATIONS, GOODWILL AND OTHER INTANGIBLE ASSETS [Abstract]
Business Combinations, Goodwill and Other Intangible Assets	5. BUSINESS COMBINATIONS, GOODWILL AND OTHER INTANGIBLE ASSETS 2019 Business Combinations Activity Aggregate terms of our acquisitions included: (1) cash paid at closing of $26.7 million (net of $3.8 million in cash acquired), (2) guaranteed deferred consideration of $6.5 million , and (3) contingent earn-out consideration of $1.5 million , which we will pay 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 goodwill of $35.6 million , identifiable intangibles of $10.1 million , other net liabilities (assumed liabilities less acquired assets) of $2.6 million , and redeemable noncontrolling interest of $8.4 million . As of March 31, 2019 , 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 our 2019 acquisitions during their open measurement periods. During the three months ended March 31, 2019 , we paid $41.2 million for deferred business acquisition and earn-out obligations for acquisitions completed in prior years. Within the 2019 acquisition activity, we completed two new strategic acquisitions, expanding our capabilities and increasing our presence in key regional markets. These strategic acquisitions are presented below.

These adjustments resulted in a $0.2 million increase to goodwill and a $0.2 million adjustment to other net liabilities. As of March 31, 2019 , we have not completed our analysis to assign fair values to all the identifiable intangible and tangible assets acquired and, therefore, we may refine the purchase price allocations for our 2018 acquisitions, with open measurement periods.

Refer to Note 8, Fair Value Measurements , and Note 12, Restructuring and Acquisition Charges , for additional discussion of our earn-out liabilities. Goodwill and Other Intangible Assets Goodwill and unamortized intangibles as of March 31, 2019 consisted of: (1) goodwill of $2,738.3 million , (2) identifiable intangibles of $289.4 million amortized over their remaining finite useful lives, and (3) $49.3 million of identifiable intangibles with indefinite useful lives that are not amortized. Significant 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.

Investments in Real Estate Ventures	6. INVESTMENTS IN REAL ESTATE VENTURES As of March 31, 2019 and December 31, 2018 , we had Investments in real estate ventures of $361.9 million and $356.9 million , respectively. Approximately 80% of our investments, as of March 31, 2019 , are in 44 separate property or commingled funds, where we co-invest alongside our clients and for which we also have an advisory agreement. Our investment ownership percentages in these funds generally range from less than 1% to 10% . The remaining 20% of our Investments in real estate ventures, as of March 31, 2019 , were attributable to investment vehicles that use our capital and outside capital primarily provided by institutional investors to invest, primarily, in certain real estate ventures that own and operate real estate. Of our investments attributable to investment vehicles, the majority was invested in LaSalle Investment Company II ("LIC II"), in which we held an effective ownership interest of 48.78% . We have maximum potential unfunded commitments to direct investments or investment vehicles of $245.6 million as of March 31, 2019 , of which $60.4 million relates to our commitment to LIC II. We evaluate our less-than-wholly-owned investments to determine whether the underlying entities are classified as variable interest entities ("VIEs"); we assess each identified VIE to determine whether we are the primary beneficiary. We have determined that we are the primary beneficiary of certain VIEs and accordingly, we have consolidated such entities. The assets of the consolidated VIEs are available only for the settlement of the obligations of the respective entities and the mortgage loans of the consolidated VIEs are non-recourse to JLL. Summarized financial information for our consolidated VIEs is presented in the following tables.

Impairment There were no significant other-than-temporary impairment charges on Investments in real estate ventures for the three months ended March 31, 2019 and 2018 . Fair Value We report a majority of our investments in real estate ventures 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 Condensed Consolidated Statements of Comprehensive Income within Equity earnings from real estate ventures.

Stock-based Compensation	7. STOCK-BASED COMPENSATION Stock Unit Awards Along with cash-based salaries and performance-based annual cash incentive awards, stock unit awards represent an important element of compensation to our employees. Restricted stock unit ("RSU") and performance stock unit ("PSU") awards activity is presented in the following tables. Shares (thousands) Weighted Average Weighted Average Remaining (in years) Unvested as of December 31, 2018 652.7 $ 131.32 2.02 Granted 74.7 152.84 Vested (195.5 ) 114.79 Forfeited (4.9 ) 126.70 Unvested as of March 31, 2019 527.0 $ 140.55 2.15 Unvested as of December 31, 2017 727.7 $ 118.96 1.24 Granted 119.3 160.86 Vested (173.8 ) 121.15 Forfeited (15.2 ) 124.62 Unvested as of March 31, 2018 658.0 $ 126.31 2.20 We determine the fair value of RSUs, subject only to service requirements, based on the closing market price of our common stock on the grant date. PSUs are subject to service requirements and one or more performance measures, including (i) performance conditions (e.g. achievement against earnings per share targets) and (ii) for certain awards, a market condition (e.g. total shareholder return performance against a peer group). We determine the fair value of PSUs based on the closing market price of our common stock on the grant date taking into consideration the likelihood of achieving each performance condition and the market condition valuation, as applicable, based on the output of a Monte Carlo simulation. As of March 31, 2019 , we had $39.1 million of unamortized deferred compensation related to unvested restricted stock units, which we anticipate recognizing over varying periods into 2023

Fair Value Measurements

Fair Value Measurements	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	8. FAIR VALUE MEASUREMENTS We measure certain assets and liabilities in accordance with ASC 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 as $667.0 million and $671.4 million as of March 31, 2019 and December 31, 2018 , respectively, using dealer quotes that are Level 2 inputs in the fair value hierarchy. The carrying value of our Long-term debt was $664.1 million and $671.5 million as of March 31, 2019 and December 31, 2018 , respectively, and included debt issuance costs of $3.5 million and $3.7 million , respectively. Investments in Real Estate Ventures at Fair Value - Net Asset Value ("NAV") We report a majority of our investments in real estate ventures 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 Condensed Consolidated Statements of Comprehensive Income within Equity earnings from real estate ventures. Of our investments reported at fair value, we generally 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 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 (1) our understanding of the methodology utilized and inputs incorporated to estimate NAV at the investee level derived through LaSalle's role as advisor or manager of these ventures, (2) consideration of market demand for the specific types of real estate assets held by each venture, and (3) contemplation of real estate and capital markets conditions in the localities in which these ventures operate. As of March 31, 2019 and December 31, 2018 , investments in real estate ventures at fair value using NAV were $200.9 million and $191.2 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. March 31, 2019 December 31, 2018 (in millions) Level 1 Level 2 Level 3 Level 1 Level 2 Level 3 Assets Investments in real estate ventures - fair value $ 45.7 — 13.0 44.6 — 11.5 Foreign currency forward contracts receivable — 6.7 — — 6.5 — Warehouse receivables — 501.3 — — 331.2 — Deferred compensation plan assets — 295.3 — — 258.2 — Mortgage banking derivative assets — — 34.8 — — 32.4 Total assets at fair value $ 45.7 803.3 47.8 44.6 595.9 43.9 Liabilities Foreign currency forward contracts payable $ — 5.3 — — 8.6 — Deferred compensation plan liabilities — 292.3 — — 251.8 — Earn-out liabilities — — 169.2 — — 192.0 Mortgage banking derivative liabilities — — 34.2 — — 26.1 Total liabilities at fair value $ — 297.6 203.4 — 260.4 218.1 Investments in Real Estate Ventures We classify one investment as Level 1 in the fair value hierarchy as quoted prices are readily available. We increase or decrease our investment each reporting period by the change in the fair value of the investment. We report these fair value adjustments in our Condensed Consolidated Statements of Comprehensive Income within Equity earnings from real estate ventures. 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. The carrying value is deemed to approximate the fair value of these investments due to the proximity of the investment date to the balance sheet date as well as investee-level performance updates. 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 our Condensed 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 inputs in the fair value hierarchy. As of March 31, 2019 and December 31, 2018 , these contracts had a gross notional value of $1.99 billion ( $0.74 billion on a net basis) and $1.99 billion ( $0.84 billion on a net basis), respectively. We recognize gains and losses from revaluation of these contracts as a component of Operating, administrative and other expense. They are offset by the gains and losses we recognize on the revaluation of intercompany loans and other foreign currency balances. The impact to net income was not significant for either the three months ended March 31, 2019 or 2018 . 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 $6.7 million asset as of March 31, 2019 , was composed of gross contracts with receivable positions of $7.4 million and payable positions of $0.7 million . The $5.3 million liability as of March 31, 2019 , was composed of gross contracts with receivable positions of $0.9 million and payable positions of $6.2 million . As of December 31, 2018 , the $6.5 million asset was composed of gross contracts with receivable positions of $6.7 million and payable positions of $0.2 million . The $8.6 million liability as of December 31, 2018 , was composed of gross contracts with receivable positions of $0.6 million and payable positions of $9.2 million . Warehouse Receivables The fair value of the Warehouse receivables is based on already locked-in security-buy prices. As of March 31, 2019 and December 31, 2018 , all of our Warehouse receivables included in our Condensed Consolidated Balance Sheet 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. The Warehouse receivables are classified as Level 2 in the fair value hierarchy as all significant inputs are readily observable. Deferred Compensation Plan We maintain a deferred compensation plan for certain of our U.S. employees that allows them to defer portions of their compensation. We invest directly in insurance contracts which yield returns to fund these deferred compensation obligations. We recognize an asset for the amount that could be realized under these insurance contracts as of the balance sheet date, and we adjust the deferred compensation obligation to reflect the changes in the fair value of the amount owed to the employees. The inputs for this valuation are Level 2 inputs in the fair value hierarchy. We recorded this plan on our Condensed Consolidated Balance Sheet as of March 31, 2019 , as Deferred compensation plan assets of $295.3 million , long-term deferred compensation plan liabilities of $292.3 million , included in Deferred compensation, and as a reduction of equity, Shares held in trust, of $5.8 million . We recorded this plan on our Condensed Consolidated Balance Sheet as of December 31, 2018 , as Deferred compensation plan assets of $258.2 million , long-term deferred compensation plan liabilities of $251.8 million , included in Deferred compensation, and as a reduction of equity, Shares held in trust, of $5.8 million . 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. We base the fair value of our earn-out liabilities on the present value of probability-weighted future cash flows related to the earn-out performance criteria on each reporting date. We determine the probability of achievement we assign to the performance criteria based on the due diligence we performed at the time of acquisition as well as actual performance achieved subsequent to acquisition. An increase to the probability of achievement would result in a higher fair value measurement. See Note 5, Business Combinations, Goodwill and Other Intangible Assets , for additional discussion of our earn-out liabilities. Mortgage Banking Derivatives The fair value of our rate lock commitments to prospective borrowers and the related inputs primarily include, as applicable, the expected net cash flows associated with closing and servicing the loan and the effects of interest rate movements between the date of the interest rate lock commitment ("IRLC") and the balance sheet date based on applicable published U.S. Treasury rates. The fair value of our forward sales contracts with prospective investors considers the market price movement of a similar security between the trade date and the balance sheet date. The market price changes are multiplied by the notional amount of the forward sales contracts to measure the fair value. Both the rate lock commitments to prospective borrowers and the forward sale contracts with prospective investors are undesignated derivatives and considered Level 3 valuations due to significant unobservable inputs related to counterparty credit risk. An increase in counterparty credit risk assumptions would result in a lower fair value measurement. The fair valuation is determined using discounted cash flow techniques, and the derivatives are marked to fair value through Revenue before reimbursements in the Condensed Consolidated Statements on Comprehensive Income. The tables below present a reconciliation for assets and liabilities measured at fair value on a recurring basis using significant unobservable inputs (Level 3).

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 three months ended March 31, 2019 or 2018 . See Note 6, Investments in Real Estate Ventures

Leases [Abstract]
Lessee Disclosure [Abstract]	9. LEASES Substantially all of our operating lease are related to office space we lease in various buildings for our own use. The terms of these non-cancelable operating leases typically require us to pay rent and a share of operating expenses and real estate taxes, generally with an inflation-based rent increase included. We also lease equipment under both operating and finance lease arrangements. Our lease agreements do not contain any material residual value guarantees or material restrictive covenants. Operating lease right-of-use assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments (e.g. rent) over the lease term beginning at the commencement date. The Operating lease right-of-use assets are adjusted for lease incentives, deferred rent, and initial direct costs, if incurred. Our leases generally do not include an implicit rate; therefore, we use an incremental borrowing rate based on information available at the lease commencement date in determining the present value of future minimum lease payments. The related lease expense is recognized on a straight-line basis over the lease term. Operating lease expense for the three months ended March 31, 2019 , was $40.2 million . Additionally, $25.7 million of operating right-of-use assets were obtained in exchange for lease obligations. Finance leases are included in Property and equipment, net of accumulated depreciation, Short-term borrowings, and Other liabilities on our Condensed Consolidated Balance Sheets. Our finance leases do not represent a significant portion of our leasing activity. As of March 31, 2019 , our total commitments related to finance leases was $11.5 million . Leases in which we sublet also do not represent a significant portion of our leasing activity.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	11. 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. 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 Condensed 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. In total, these receivables were $38.1 million and $40.6 million as of March 31, 2019 and December 31, 2018 , respectively, and are included in Notes and other receivables and Long-term receivables on our Condensed Consolidated Balance Sheets. The following table shows the professional indemnity accrual activity and related payments. (in millions) December 31, 2018 $ 43.1 New claims — Prior year claims adjustments (2.4 ) Claims paid (1.1 ) March 31, 2019 $ 39.6 December 31, 2017 $ 26.7 New claims 2.2 Prior year claims adjustments 13.9 Claims paid (1.6 ) March 31, 2018 $ 41.2 As a lender in the Fannie Mae Delegated Underwriting and Servicing ("DUS") program, we retain a portion of the risk of loss for loans we originate and sell under the DUS program. The net loss on defaulted loans are shared with Fannie Mae based upon established loss-sharing ratios. Generally, our share of losses is capped at 20% of the principal balance of the mortgage at origination. As of March 31, 2019 and December 31, 2018 , we had loans, funded and sold, subject to such loss-sharing arrangements with an aggregate unpaid principal balance of $8.6 billion and $8.4 billion , respectively. As of March 31, 2019 and December 31, 2018 , loan loss accruals were both $17.5 million and are included in Other liabilities on our Condensed Consolidated Balance Sheets. There were no loan losses incurred for the three months ended March 31, 2019 and 2018

Restructuring and acquisition charges	12. RESTRUCTURING AND ACQUISITION CHARGES For the three months ended March 31, 2019 and 2018, we recognized Restructuring and acquisition charges of $18.6 million and $0.7 million , respectively, which included $5.7 million of net increases and $1.2 million of net decreases, respectively, that arose from prior-period acquisition activity. In all periods, the remaining charges primarily consist of (1) severance and employment-related charges, including those related to external service providers, incurred in conjunction with a structural business shift, which can be represented by a notable change in headcount, change in leadership, or transformation of business processes, (2) lease exit charges, and (3) other restructuring, acquisition and integration-related charges.

New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	2. NEW ACCOUNTING STANDARDS Recently adopted accounting guidance In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) , which increases transparency and comparability by requiring the recognition of lease assets and lease liabilities on the balance sheet, as well as requiring the disclosure of key information about leasing arrangements. On January 1, 2019, we adopted ASU No. 2016-02, Leases (ASC Topic 842) , on a modified retrospective basis under the optional transition method. Therefore, the application of the provisions of this ASU are effective January 1, 2019, and comparative periods are presented in accordance with ASC Topic 840. Additionally, we elected the package of practical expedients permitted under the transition guidance within the new standard, which allowed us to carry forward (1) our historical lease classification and assessments for expired and existing leases, and (2) our historical accounting for initial direct costs for existing leases. We elected not to record on the Condensed Consolidated Balance Sheets any lease whose term is 12 months or less and does not include a purchase option that we are reasonably certain to exercise. We also elected to account for the non-lease components within our leases as part of the single lease component to which they are related. The most significant impact of the adoption of this ASU was an increase to the Condensed Consolidated Balance Sheets to reflect operating lease right-of-use assets and lease liabilities, which are primarily associated with our office leases around the world. Our accounting for finance leases was not materially impacted. See Note 9, Leases , for additional information on the impact of ASC 842 adoption. In January 2017, the FASB issued ASU No. 2017-04, Simplifying the Test for Goodwill Impairment , which eliminates Step 2 from the goodwill impairment test. The annual goodwill impairment test will require companies to compare the fair value of a reporting unit with its carrying amount and recognize an impairment charge when the carrying amount exceeds the fair value of the reporting unit. This ASU is effective for annual and interim goodwill impairment tests beginning after December 15, 2019, with early adoption permitted. We adopted this guidance effective January 1, 2019, and, as a result, will no longer apply Step 2 when performing the goodwill impairment test. This guidance had no material impact on our financial statements and related disclosures. Recently issued accounting guidance, no t yet adopted In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) , which creates a new framework to evaluate financial instruments, such as trade receivables, for expected credit losses. This new framework replaces the existing incurred loss approach and is expected to result in more timely recognition of credit losses. ASU No. 2016-13 is effective for annual and interim periods beginning after December 15, 2019. We are currently evaluating the effect this guidance will have on our financial statements and related disclosures. In August 2018, the FASB issued ASU No. 2018-15, Customer's Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That is a Service Contract
