Notes to Consolidated Financial Statements	JONES LANG LASALLE INCORPORATED Notes to Consolidated Financial Statements (Unaudited) 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 "the Firm," "we," "us" or "our") for the year ended December 31, 2014 , which are included in our 2014 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 and to Note 2, Summary of Significant Accounting Policies, in the Notes to Consolidated Financial Statements in our 2014 Annual Report on Form 10-K for further discussion of our significant accounting policies and estimates.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Interim Information	(1) Interim Information Our Consolidated Financial Statements as of September 30, 2015 , and for the three months and nine months ended September 30, 2015 and 2014 , are unaudited. In the opinion of management, all adjustments (consisting solely of normal recurring adjustments) necessary for a fair presentation of the Consolidated Financial Statements for these interim periods have been included. Certain prior year amounts have been reclassified 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 we recognize certain expenses evenly throughout the year. Our LaSalle Investment Management ("LaSalle") segment generally earns investment-generated performance fees on clients' real estate investment returns and co-investment equity gains when assets are sold, the timing of which is geared toward the benefit of our clients. Within our Real Estate Services ("RES") segments, revenue from capital markets activities relates to 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 is based on forecasted income by country and expected enacted tax rates. 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 September 30, 2015 and 2014 are not indicative of what our results will be for the full fiscal year.

Accounting Policies [Abstract]
New Accounting Standards	(2) New Accounting Standards On May 28, 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, "Revenue from Contracts with Customers," which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. generally accepted accounting principles ("U.S. GAAP") when it becomes effective. The new standard is effective for annual and interim periods in fiscal years beginning after December 15, 2017, with early adoption permitted for annual and interim periods in fiscal years beginning after December 15, 2016. The standard permits the use of either the retrospective or cumulative effect transition method. The Company is evaluating the effect that ASU 2014-09 will have on its consolidated financial statements and related disclosures. The Company has not yet selected a date of adoption or a transition method. In February 2015, the FASB issued ASU No. 2015-02, "Amendments to the Consolidation Analysis," which improves targeted areas of the consolidation guidance and reduces the number of consolidation models. The amendments in the ASU are effective for annual and interim periods in fiscal years beginning after December 15, 2015, with early adoption permitted. The Company is currently evaluating the effect the guidance will have on its consolidated financial statements. In April 2015, the FASB issued ASU No. 2015-03, "Interest - Imputation of Interest," which simplifies the presentation of debt issuance costs. The amendments in the ASU are effective for annual and interim periods in fiscal years beginning after December 15, 2015, with early adoption permitted. The Company does not believe implementation of the guidance will have a material effect on its consolidated financial statements. In September 2015, the FASB issued ASU No. 2015-16, "Business Combinations: Simplifying the Accounting for Measurement-Period Adjustments," which eliminates the requirement for an acquirer to retrospectively adjust the financial statements for measurement-period adjustments that occur in periods after a business combination is consummated. The ASU is effective for annual and interim periods in fiscal years beginning after December 15, 2015, with early adoption permitted. The Company adopted this ASU upon issuance, noting that the pronouncement did not have a material effect on its consolidated financial statements.

Revenue Recognition

Revenue Recognition [Abstract]
Revenue Recognition	(3) Revenue Recognition We earn revenue from the following principal sources: • Transaction commissions; • Advisory and management fees; • Incentive fees; • Project and development management fees; and • Construction management fees. We recognize transaction commissions related to leasing services and capital markets services as revenue when we provide the related services unless future contingencies exist. Advisory and management fees related to property and facility management services, valuation services, corporate property services, consulting services and investment management are recognized in the period in which we perform the related services. We recognize incentive fees in the period earned, based on the performance of funds' investments, contractual benchmarks and other contractual formulas. If future contingencies exist, we defer recognition of the related revenue until the respective contingencies have been satisfied. We recognize project and development management and construction management fees by applying the percentage of completion method of accounting. The efforts expended method is used to determine the extent of progress towards completion for project and development management fees, and the costs incurred to total estimated costs method is used for construction management fees. Gross and Net Accounting: We follow the guidance of FASB Accounting Standards Codification ("ASC") 605-45, "Principal and Agent Considerations," when accounting for reimbursements received from clients. In certain of our businesses, primarily those involving management services, our clients reimburse us for expenses incurred on their behalf. We base the treatment of reimbursable expenses for financial reporting purposes upon the fee structure of the underlying contract. Accordingly, we report a contract that provides for fixed fees, fully inclusive of all personnel and other recoverable expenses, on a gross basis. When accounting on a gross basis, our reported revenue comprises the entire amount billed to our client and our reported expenses include all costs associated with the client. Certain contractual arrangements in our project and development services, including fit-out business activities and our facility management services, tend to have characteristics that result in accounting on a gross basis. In Note 4, Business Segments, for client assignments in property and facility management and in project and development services that are accounted for on a gross basis, we identify the gross contract costs, including vendor and subcontract costs ("gross contract costs"), and present separately their impact on both revenue and operating expenses in our RES segments. We exclude these gross contract costs from revenue and operating expenses in determining "fee revenue" and "fee-based operating expenses" in our segment presentation. We account for a contract on a net basis when the fee structure is comprised of at least two distinct elements, namely (1) a fixed management fee and (2) a separate component that allows for scheduled reimbursable personnel costs or other expenses to be billed directly to the client. When accounting on a net basis, we include the fixed management fee in reported revenue and net the reimbursement against expenses. We base this accounting on the following factors, which define us as an agent rather than a principal: • The property owner or client, with ultimate approval rights relating to the employment and compensation of on-site personnel, and bearing all of the economic costs of such personnel, is determined to be the primary obligor in the arrangement; • Reimbursement to JLL is generally completed simultaneously with payment of payroll or soon thereafter; • The property owner is contractually obligated to fund all operating costs of the property from existing cash flow or direct funding from its building operating account and JLL bears little or no credit risk; and • JLL generally earns no margin on the reimbursement aspect of the arrangement, obtaining reimbursement only for actual costs incurred. We account for the majority of our service contracts on a net basis. The reimbursable costs associated with these net contracts aggregated approximately $499.2 million and $465.4 million for the three months ended September 30, 2015 and 2014 , respectively, and $1.5 billion and $1.4 billion for the nine months ended September 30, 2015 and 2014 , respectively. The presentation of expenses pursuant to these arrangements under either a gross or net basis has no impact on operating income, net income or cash flows. Contracts accounted for on a gross basis resulted in certain costs reflected in revenue and operating expenses (gross contract costs) of $214.0 million and $185.4 million for the three months ended September 30, 2015 and 2014 , respectively, and $580.0 million and $536.3 million for the nine months ended September 30, 2015 and 2014 , respectively.

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 and hotels, property management, facilities management, project and development management, energy management and sustainability, construction management, and advisory, consulting and valuation services. We consider "property management" to represent services provided to non-occupying property investors and "facilities management" to represent services provided to owner-occupiers. 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, we present revenue net of gross contract costs in our RES segments. Excluding these costs from revenue and expenses results in a "net" presentation of "fee revenue" and "fee-based operating expenses" that we believe more accurately reflects how we manage our expense base and operating margins. See Note 3 for additional information on our gross and net accounting policies. For segment reporting, we present Equity earnings from real estate ventures within total segment revenue, since the related activity is an integral part of LaSalle. Finally, our measure of segment results excludes Restructuring and acquisition charges.

BUSINESS COMBINATIONS, GOODWILL AND OTHER INTANGIBLE ASSETS [Abstract]
Business Combinations, Goodwill and Other Intangible Assets	(5) Business Combinations, Goodwill and Other Intangible Assets 2015 Business Combinations Activity During the nine months ended September 30, 2015 , we completed 12 acquisitions, acquiring companies in Australia, Canada, England, Germany, Japan, Poland, Sweden, Turkey and the United States, and we made the final payments for acquisitions of businesses located in India and Turkey that were completed in previous years. Aggregate terms of these acquisitions included: (1) cash payments of $102.9 million , including the $16.4 million related to the Indian business acquisition further discussed below, (2) consideration of $14.2 million subject only to the passage of time, and (3) earn-out consideration of $36.9 million subject to provisions that will be paid upon certain performance conditions being met which are recorded at their acquisition date fair value. Our 2007 acquisition of an Indian real estate services company included provisions for the purchase of the minority ownership retained at completion. This obligation was reflected on our Consolidated Balance Sheet at December 31, 2014 as an $11.2 million Minority shareholder redemption liability. During the nine months ended September 30, 2015 , this obligation was adjusted upwards by $5.2 million to the final settlement amount of $16.4 million for the remaining shares, which was paid during June 2015. A corresponding adjustment of $5.2 million was recorded to goodwill. During the nine months ended September 30, 2015 , we paid $48.8 million for deferred business acquisition and earn-out obligations for acquisitions completed in prior years. We also paid $2.7 million to acquire a portion of the redeemable noncontrolling interest related to our 2014 acquisition of Tenzing AB, a Swedish real estate services provider. On August 13, 2015, the Company announced that Jones Lang LaSalle Investments, LLC and Jones Lang LaSalle Operations, L.L.C., each wholly-owned indirect subsidiaries of the Company, entered into an Agreement and Plan of Merger with Oak Grove Commercial Mortgage, LLC, a Delaware limited liability company (“Oak Grove”) and certain affiliates of Oak Grove. The acquisition of Oak Grove brings greater full-service mortgage lending and mortgage banking capabilities to JLL. Oak Grove's Fannie Mae, Freddie Mac and HUD/GNMA capabilities will expand JLL’s market-rate, affordable, seniors housing and healthcare financial expertise, and complement its multifamily sales and equity services. The cash consideration payable at closing was equal to $175.0 million from which Oak Grove retired outstanding indebtedness (excluding warehouse loans/lines) and redeemed its preferred unit holders. Oak Grove has the potential to earn future payments based on a five-year earn-out structure tied to performance of the combined platform such that total consideration payable could be up to $300.0 million . The expected total consideration payable pursuant to the Agreement and Plan of Merger is approximately $260.0 million . As noted within Note 14, Subsequent Events, the transaction closed on October 30, 2015. Following the merger, Oak Grove was renamed Jones Lang LaSalle Multifamily, LLC. Earn-Out Payments At September 30, 2015 , we had the potential to make future earn-out payments on 21 acquisitions that are subject to the achievement of certain performance conditions. The maximum amount of potential future earn-out payments was $84.9 million at September 30, 2015 , for which we have accrued $57.9 million on our Consolidated Balance Sheet within Other current and long-term liabilities. As of December 31, 2014, we had accrued $25.1 million for future earn-out payments that had aggregate maximum future potential payments of $43.5 million . Assuming the achievement of the applicable performance conditions, we anticipate that the majority of these earn-out payments will be paid over the next four years. Goodwill and Other Intangible Assets We had $2.0 billion of goodwill and unamortized intangibles at September 30, 2015 . Significant portions of our goodwill and unamortized intangibles are denominated in currencies other than the U.S. dollar, which means that a portion of the movements in the reported book value of these balances is attributable to movements in foreign currency exchange rates. The tables below detail the foreign exchange impact on our goodwill and intangible balances. The $2.0 billion of goodwill and unamortized intangibles consists of: (1) goodwill of $2.00 billion with an indefinite useful life that is not amortized, (2) identifiable intangibles of $37.4 million that will be amortized over their remaining finite useful lives, and (3) $6.0 million of identifiable intangibles with indefinite useful lives that are not amortized. The following table details, by reporting segment, the current year movements in goodwill with indefinite useful lives ($ in millions): Real Estate Services Americas EMEA Asia Pacific LaSalle Consolidated Balance as of January 1, 2015 $ 1,008.3 650.4 230.8 18.4 1,907.9 Additions, net of adjustments 15.3 77.5 42.5 — 135.3 Impact of exchange rate movements (0.8 ) (32.8 ) (9.5 ) (0.5 ) (43.6 ) Balance as of September 30, 2015 $ 1,022.8 695.1 263.8 17.9 1,999.6 The following table details, by reporting segment, the current year movements in the gross carrying amount and accumulated amortization of our identifiable intangibles ($ in millions): Real Estate Services Americas EMEA Asia Pacific LaSalle Consolidated Gross book value Balance as of January 1, 2015 $ 103.4 43.8 9.5 7.0 163.7 Additions 4.6 6.1 5.3 — 16.0 Impact of exchange rate movements (0.1 ) (1.9 ) (0.5 ) (0.9 ) (3.4 ) Balance as of September 30, 2015 $ 107.9 48.0 14.3 6.1 176.3 Accumulated amortization Balance as of January 1, 2015 $ (84.9 ) (31.0 ) (8.9 ) (0.1 ) (124.9 ) Amortization expense (5.3 ) (2.4 ) (1.7 ) — (9.4 ) Impact of exchange rate movements — 1.3 0.1 — 1.4 Balance as of September 30, 2015 $ (90.2 ) (32.1 ) (10.5 ) (0.1 ) (132.8 ) Net book value as of September 30, 2015 $ 17.7 15.9 3.8 6.0 43.4 We amortize our identifiable intangible assets with finite lives on a straight-line basis over their useful lives.

Equity Method Investments and Joint Ventures [Abstract]
Investments in Real Estate Ventures	(6) Investments in Real Estate Ventures As of September 30, 2015 and December 31, 2014 , we had Investments in real estate ventures of $311.8 million and $297.1 million , respectively. We account for the majority of our investments in real estate ventures under the equity method of accounting, however, we report certain of our direct investments at fair value. Our investments are primarily co-investments in approximately 50 separate property or commingled funds for which we also have an advisory agreement. Our investment ownership percentages in these funds range from less than 1% to 15% . Approximately half of our $311.8 million balance in Investments in real estate ventures as of September 30, 2015 was attributable to investment vehicles which, utilizing our capital and outside capital primarily provided by institutional investors, invest in certain real estate ventures that own and operate real estate. Of this amount, the majority was placed with LaSalle Investment Company II ("LIC II"), in which we held an effective ownership interest of 48.78% . The remainder of our Investments in real estate ventures primarily represented direct investments in certain real estate ventures that own and operate real estate. At September 30, 2015 , LIC II had unfunded capital commitments to underlying ventures of $119.5 million and a $20.0 million revolving credit facility (the "LIC II Facility"), principally for working capital needs. LIC II's exposure to the liabilities and losses of the underlying real estate ventures in which it has invested is limited to existing capital contributions and remaining unfunded capital commitments. Considering our proportionate share of LIC II's commitments to underlying funds and our exposure to fund our proportionate share of the then outstanding balance on the LIC II facility, our maximum potential unfunded commitment to LIC II was $88.7 million as of September 30, 2015 . We expect LIC II to draw down on our commitments over the next 3 to 5 years to satisfy its existing commitments to underlying real estate ventures. The following table summarizes the above discussion relative to LIC II as of September 30, 2015 ($ in millions): Our effective ownership interest in co-investment vehicle 48.78 % Our maximum potential unfunded commitments $ 88.7 Our share of unfunded capital commitments to underlying funds 58.3 Our share of exposure on outstanding borrowings 0.1 Our maximum exposure, assuming facility is fully drawn 9.8 Exclusive of our LIC II commitment structure, we have potential unfunded commitment obligations to other like investment vehicles or direct investments, the aggregate maximum of which is $78.5 million as of September 30, 2015 . We evaluate our less-than-wholly-owned investments to determine whether the underlying entities are classified as variable interest entities ("VIEs"); each identified VIE is assessed to determine whether we are the primary beneficiary. We have determined that we are the primary beneficiary of certain VIEs and accordingly, consolidate such entities. The assets of the consolidated VIEs are available only for the settlement of the obligations of the respective entities and the mortgage loans of the consolidated VIEs are non-recourse to JLL. Summarized balance sheets for our consolidated VIEs as of September 30, 2015 and December 31, 2014 are as follows ($ in millions): September 30, 2015 December 31, 2014 Property and equipment, net $ 32.5 37.8 Investment in real estate venture 3.3 5.0 Other assets 4.7 3.5 Total assets $ 40.5 46.3 Mortgage loans payable, included in other long-term liabilities $ 25.6 29.3 Total liabilities 25.6 29.3 Members' equity 14.9 17.0 Total liabilities and members' equity $ 40.5 46.3 Summarized statements of operations for our consolidated VIEs for the three and nine months ended September 30, 2015 and 2014 are as follows ($ in millions): Three Months Ended Three Months Ended Nine Months Ended Nine Months September 30, 2015 September 30, 2014 September 30, 2015 September 30, 2014 Revenue (1) $ 4.6 1.3 $ 7.1 2.9 Gain on sale of investment — — 1.3 — Operating and other expenses (1.0 ) (1.3 ) (2.8 ) (2.7 ) Net income $ 3.6 — $ 5.6 0.2 (1) Includes $3.3 million for the three and nine months ended September 30, 2015, representing our pro rata share of the gain on the sale of real estate by an investment of one of our consolidated VIE's that was accounted for pursuant to the equity method. The members' equity and net income of the consolidated VIEs are allocated to the noncontrolling interest holders to the extent of their ownership as Noncontrolling interest on our Consolidated Balance Sheets and as Net income attributable to noncontrolling interest in our Consolidated Statements of Comprehensive Income, respectively. Impairment We review our investments in real estate ventures on a quarterly basis, or as otherwise deemed necessary, for indications that we may not be able to recover the carrying value of our investments and whether such investments are other than temporarily impaired. Our assessments consider the existence of impairment indicators at the underlying real estate assets that comprise the majority of our investments. Such assessments, in regards to both the investment levels and underlying asset levels, are based on evaluations of regular updates to future cash flow models and on factors such as operational performance, market conditions, major tenancy matters, legal and environmental concerns, and our ability and intent to hold each investment. When events or changes in circumstances indicate that the carrying amount of one of our investments in real estate ventures may be other than temporarily impaired, we consider the likelihood of recoverability of the carrying amount of our investment as well as the estimated fair value and record an impairment charge as applicable. Impairment charges to write down the carrying value of the real estate assets underlying our investments, our proportionate share of which is recognized within Equity earnings from real estate ventures, are generally the result of completing discounted cash flow models that primarily rely upon Level 3 inputs to determine fair value. Impairment charges recorded within Equity earnings from real estate ventures aggregated to $0.1 million and $1.1 million for the three months ended September 30, 2015 and 2014 , respectively, and $4.2 million and $2.0 million for the nine months ended September 30, 2015 and 2014 , respectively. Fair Value We report our investments in certain real estate ventures at fair value. For such investments, we increase or decrease our investment each reporting period by the estimated change in fair value, which activity is reflected as gains or losses in our Consolidated Statements of Comprehensive Income within Equity earnings from real estate ventures. At September 30, 2015 and December 31, 2014 , we had $150.3 million and $113.6 million , respectively, of investments that were reported at fair value. Fair value was estimated utilizing net asset value (''NAV'') per share (or its equivalent), generally a Level 3 input in the fair value hierarchy, as provided by our investees. Critical inputs to NAV estimates included valuations of the underlying real estate assets and borrowings, which incorporate investment-specific assumptions such as discount rates, capitalization rates, rental and expense growth rates and asset-specific market borrowing rates. No adjustments to NAV estimates provided by investees, including adjustments to contemplate any restrictions to the transferability of ownership interests embedded within investment agreements to which we are a party, were considered necessary based upon the following factors: (1) our understanding of the methodology utilized and inputs incorporated to estimate NAV at the investee level derived through LaSalle's role as advisor or manager of these ventures; (2) consideration of market demand for the specific types of real estate assets held by each venture; and (3) contemplation of real estate and capital markets conditions in the localities in which these ventures operate. The following table shows the roll forward of our investments in real estate ventures that are accounted for at fair value ($ in millions): 2015 2014 Fair value investments as of January 1, $ 113.6 78.9 Investments 28.0 18.2 Distributions (5.6 ) (2.2 ) Net fair value gain 18.5 8.3 Foreign currency translation adjustments, net (4.2 ) (2.2 ) Fair value investments as of September 30, $ 150.3 101.0

Stock-based Compensation	(7) Stock-Based Compensation Restricted Stock Unit Awards Along with cash-based salaries and performance-based annual cash incentive awards, restricted stock unit awards represent an important element of our compensation program. Restricted stock unit activity for the three months ended September 30, 2015 and 2014 is as follows: Shares Weighted Average Weighted Average Unvested at July 1, 2015 805.4 $ 102.39 Granted 27.6 149.94 Vested (129.9 ) 75.79 Forfeited (4.1 ) 96.94 Unvested at September 30, 2015 699.0 $ 109.24 2.24 Unvested shares expected to vest 679.2 $ 109.42 2.24 Unvested at July 1, 2014 1,025.9 $ 81.95 Granted 6.9 130.46 Vested (276.2 ) 61.52 Forfeited (2.8 ) 84.93 Unvested at September 30, 2014 753.8 $ 89.86 2.61 Unvested shares expected to vest 730.3 $ 90.00 2.61 Restricted stock unit activity for the nine months ended September 30, 2015 and 2014 is as follows: Shares Weighted Average Weighted Average Unvested at January 1, 2015 745.3 $ 90.43 Granted 158.0 159.00 Vested (186.1 ) 77.65 Forfeited (18.2 ) 93.82 Unvested at September 30, 2015 699.0 $ 109.24 2.24 Unvested shares expected to vest 679.2 $ 109.42 2.24 Unvested at January 1, 2014 1,025.3 $ 73.09 Granted 155.8 119.19 Vested (416.3 ) 59.78 Forfeited (11.0 ) 80.21 Unvested at September 30, 2014 753.8 $ 89.86 2.61 Unvested shares expected to vest 730.3 $ 90.00 2.61 We determine the fair value of restricted stock units based on the closing market price of the Company's common stock on the grant date. As of September 30, 2015 , we had $31.1 million of unamortized deferred compensation related to unvested restricted stock units, which is anticipated to be recognized over varying periods into 2020 . Shares vested during the three months ended September 30, 2015 and 2014 had grant date fair values of $9.8 million and $17.0 million , respectively, and $14.4 million and $24.9 million for the nine months ended September 30, 2015 and 2014 , respectively. Shares granted during the three months ended September 30, 2015 and 2014 , had grant date fair values of $4.1 million and $0.9 million , respectively, and $25.1 million and $18.6 million for the nine months ended September 30, 2015 and 2014 , respectively. Other Stock Compensation Programs We maintain a stock-based compensation plan for our United Kingdom and Ireland-based employees, the Jones Lang LaSalle Savings Related Share Option Plan ("Save as You Earn" or "SAYE"). Under this plan, employees make an annual election to contribute to the plan to purchase stock at a 15% discount from the market price at the beginning of the plan's three and five year vesting periods. No options were issued during the nine months ended September 30, 2015 . In July 2014, we issued approximately 47,600 options under the SAYE plan at an exercise price of $105.54. The fair value of options granted under the SAYE plan are amortized over their respective vesting periods. There were approximately 90,600 and 176,400 options outstanding under the SAYE plan at September 30, 2015 and December 31, 2014 , respectively.

Pension and Other Postretirement Benefits Disclosure	(8) Retirement Plans We maintain four contributory defined benefit pension plans in the United Kingdom, Ireland and Holland to provide retirement benefits to eligible employees. We use a December 31 measurement date for our plans. Net periodic pension cost (income) consisted of the following ($ in millions): Three Months Three Months Nine Months Ended Nine Months September 30, 2015 September 30, 2014 September 30, 2015 September 30, 2014 Employer service cost - benefits earned during the period $ 1.3 1.0 $ 3.9 2.9 Interest cost on projected benefit obligation 3.7 4.1 11.0 12.3 Expected return on plan assets (5.3 ) (6.2 ) (15.8 ) (18.6 ) Net amortization of deferrals 0.8 0.3 2.4 0.8 Recognized actuarial loss 0.4 — 1.2 0.1 Net periodic pension cost (income) $ 0.9 (0.8 ) $ 2.7 (2.5 ) The expected return on plan assets, included in net periodic pension cost (income) during 2015 was based on forecasted long-term rates of return on the plan assets of each individual plan; expected returns range from 2.7% to 5.8% . For the three months ended September 30, 2015 and 2014 , we made payments of $3.9 million and $5.4 million , respectively, to these plans. For the nine months ended September 30, 2015 and 2014 , we made payments of $9.3 million and $12.0 million , respectively, to these plans. We expect to contribute an additional $3.1 million to these plans during the last three months of 2015 , for a total of $12.4 million in 2015 . We contributed $14.6 million to these plans during the year ended December 31, 2014 .

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	(9) Fair Value Measurements ASC 820, "Fair Value Measurements and Disclosures," establishes a framework for measuring fair value highlighted by the following three-tier fair value hierarchy: • Level 1. Observable inputs such as quoted prices for identical assets or liabilities in active markets; • Level 2. Inputs, other than the 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. There were no transfers among levels of valuations during either the three and nine months ended September 30, 2015 or 2014 . Financial Instruments Our financial instruments include Cash and cash equivalents, Trade receivables, Notes and other receivables, Warehouse receivables, Accounts payable, Short-term borrowings, Warehouse facility, Credit facility, Long-term senior notes and foreign currency exchange contracts. The estimated fair value of Cash and cash equivalents, Trade receivables, Notes and other receivables, Warehouse receivables, Accounts payable, and the Warehouse facility approximates their carrying amounts due to the short maturity of these instruments. The estimated fair value of our Credit facility and Short-term borrowings approximates their carrying value given the variable interest rate terms and market spreads. We estimated the fair value of our Long-term senior notes as $284.3 million and $285.3 million at September 30, 2015 and December 31, 2014 , respectively, using dealer quotes that are Level 2 inputs in the fair value hierarchy. The carrying value of our Long-term senior notes was $275.0 million at September 30, 2015 and December 31, 2014 . We record Warehouse receivables at the lower of cost or fair value based on the committed purchase price. When applicable, we determine the fair value of Warehouse receivables based on readily observable Level 2 inputs. Recurring Fair Value Measurements The following table categorizes by level in the fair value hierarchy the estimated fair value at September 30, 2015 and December 31, 2014 of our assets and liabilities that are measured at fair value on a recurring basis ($ in millions): September 30, 2015 December 31, 2014 Level 2 Level 3 Level 2 Level 3 Assets Foreign currency forward contracts receivable $ 2.7 — $ 10.5 — Deferred compensation plan assets 128.9 — 111.2 — Investments in real estate ventures - fair value — 150.3 — 113.6 Total assets at fair value $ 131.6 150.3 $ 121.7 113.6 Liabilities Foreign currency forward contracts payable $ 15.2 — $ 18.2 — Deferred compensation plan liabilities 124.5 — 107.9 — Total liabilities at fair value $ 139.7 — $ 126.1 — 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. We estimate the fair value of these contracts based on current market rates. The inputs for these valuations are Level 2 inputs in the fair value hierarchy. At September 30, 2015 , these forward exchange contracts had a gross notional value of $1.86 billion ( $968.0 million on a net basis) and were recorded on our Consolidated Balance Sheet as Other current assets of $2.7 million and Other current liabilities of $15.2 million . At December 31, 2014 , these forward exchange contracts had a gross notional value of $2.03 billion ( $1.19 billion on a net basis) and were recorded on our Consolidated Balance Sheet as Other current assets of $10.5 million and Other current liabilities of $18.2 million . The revaluations of our foreign currency forward contracts resulted in net losses of $12.5 million and $17.2 million for the three months ended September 30, 2015 and 2014 , respectively. Gains and losses from the revaluation of these contracts are recognized as a component of Operating, administrative and other expense and are offset by the gains and losses recognized on the revaluation of intercompany loans and other foreign currency balances such that the impact to net income was not significant for either of the three or nine months ended September 30, 2015 or 2014 . The asset and liability positions recorded for our foreign currency forward contracts are based on the net payable or net receivable position with the financial institutions from which we purchase these contracts. The $2.7 million asset at September 30, 2015 was comprised of gross contracts with receivable positions of $3.7 million and payable positions of $1.0 million . The $15.2 million liability at September 30, 2015 was comprised of gross contracts with receivable positions of $5.7 million and payable positions of $20.9 million . At December 31, 2014 , the $10.5 million asset was comprised of gross contracts with receivable positions of $12.5 million and payable positions of $2.0 million . The $18.2 million liability at December 31, 2014 , was comprised of gross contracts with receivable positions of $1.1 million and payable positions of $19.3 million . 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 at the balance sheet date, and the deferred compensation obligation is adjusted 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. This plan was recorded on our Consolidated Balance Sheet at September 30, 2015 , as Deferred compensation plan assets of $128.9 million within current assets, long-term Deferred compensation liabilities of $124.5 million , and as a reduction of equity, Shares held in trust, of $6.3 million . This plan was recorded on our Consolidated Balance Sheet at December 31, 2014 as Deferred compensation plan assets of $111.2 million , long-term Deferred compensation liabilities of $107.9 million , and as a reduction of equity, Shares held in trust, of $6.4 million . Investments in Real Estate Ventures We report certain direct investments in real estate ventures at fair value. We had $150.3 million and $113.6 million at September 30, 2015 and December 31, 2014 , respectively, of direct investments in real estate ventures that were reported at fair value. For these investments in real estate ventures, we increase or decrease our investment each reporting period by the change in the fair value of these investments. These fair value adjustments are reported in our Consolidated Statements of Comprehensive Income within Equity earnings from real estate ventures. As discussed in Note 6, Investments in Real Estate Ventures, we estimate the fair value of these investments using NAV per share (or its equivalent), generally a Level 3 input in the fair value hierarchy, provided by investees. Non-Recurring Fair Value Measurements We review our investments in real estate ventures, except those investments otherwise reported at fair value, on a quarterly basis, or as otherwise deemed necessary, for indications of whether we may not be able 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 three or nine months ended September 30, 2015 or 2014 . See Note 6, Investments in Real Estate Ventures, for additional information, including information related to impairment charges recorded at the investee level.

Debt Disclosure [Abstract]
Debt	(10) Debt Credit Facility On February 25, 2015, we amended and expanded our credit facility (the "Facility"), which resulted in: (1) an increase in our borrowing capacity from $1.2 billion to $2.0 billion ; (2) an extension of the maturity date from October 4, 2018 to February 25, 2020; (3) increases in certain add-backs to Adjusted EBITDA (as defined in the Facility) for the calculation of the leverage ratio to provide additional operating flexibility; and (4) a range of pricing from LIBOR plus 1.00% to 2.05% , with pricing as of September 30, 2015 at LIBOR plus 1.00% . Under this new agreement, our leverage ratio cannot exceed 3.50 to 1, except immediately following a material acquisition, in which case, the leverage ratio maximum is 4.00 to 1 for up to four consecutive quarters. Other key terms and conditions of the Facility were unchanged as part of the current amendment and expansion. At September 30, 2015 , we had outstanding borrowings under the Facility of $235.0 million and outstanding letters of credit of $19.1 million . At December 31, 2014 , we had no outstanding borrowings under the Facility and outstanding letters of credit of $22.0 million . The average outstanding borrowings under the Facility were $334.7 million and $412.0 million during the three months ended September 30, 2015 and 2014 , respectively, and $296.7 million and $392.9 million during the nine months ended September 30, 2015 and 2014 , respectively. The effective interest rates on our Facility were 1.2% and 1.4% for the three months ended September 30, 2015 and 2014 , respectively, and 1.1% and 1.2% during the nine months ended September 30, 2015 and 2014 . We remained in compliance with all covenants under our Facility as of September 30, 2015 , including a minimum cash interest coverage ratio of 3.00 to 1 and the maximum leverage ratio discussed above. Included in debt for the calculation of the leverage ratio is the present value of deferred business acquisition obligations and included in Adjusted EBITDA (as defined in the Facility) are, among other things, (1) an add-back for stock-based compensation expense, (2) the addition of the EBITDA of acquired companies earned prior to acquisition, and (3) add-backs for certain impairment and non-recurring charges. In addition, we are restricted from, among other things, incurring certain levels of indebtedness to lenders outside of the Facility and disposing of a significant portion of our assets. Lender approval or waiver is required for certain levels of cash acquisitions and co-investment. We will continue to use the Facility for business acquisitions, working capital needs (including payment of accrued incentive compensation), co-investment activities, dividend payments, share repurchases, and capital expenditures. Short-Term Borrowings In addition to our Facility, we have the capacity to borrow up to an additional $42.8 million under local overdraft facilities. We had short-term borrowings (including capital lease obligations and local overdraft facilities) of $30.5 million and $19.6 million at September 30, 2015 and December 31, 2014 , respectively, of which $19.9 million and $14.6 million at September 30, 2015 and December 31, 2014 , respectively, was attributable to local overdraft facilities. Long-Term Senior Notes In November 2012 , in an underwritten public offering, we issued $275.0 million of Long-term senior notes due November 2022 (the "Notes"). The Notes bear interest at an annual rate of 4.4% , subject to adjustment if a credit rating assigned to the Notes is downgraded below an investment grade rating (or subsequently upgraded). Interest is payable semi-annually on May 15 and November 15 .

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. Many of these litigation matters are covered by insurance (including insurance provided through a consolidated captive insurance company as further discussed below), but they may nevertheless be subject to large deductibles and the amounts being claimed may exceed the available insurance. Although the ultimate liability for these matters cannot be determined, based upon information currently available, we believe the ultimate resolution of such claims and litigation will not have a material adverse effect on our financial position, results of operations or liquidity. 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 $2.5 million per claim, inclusive of the deductible. When a potential loss event occurs, management estimates the ultimate cost of the claim and accrues the related cost in Other current and long-term liabilities on our Consolidated Balance Sheets when probable and estimable. The following table shows the professional indemnity accrual activity and the related payments made during the nine months ended September 30, 2015 and 2014 ($ in millions): Accrual Activity January 1, 2015 $ 9.2 New claims 2.4 Prior year claims adjustments 0.2 Claims paid (0.3 ) September 30, 2015 $ 11.5 January 1, 2014 $ 6.2 New claims 6.8 Prior year claims adjustments (0.5 ) Claims paid (2.0 ) September 30, 2014 $ 10.5

Restructuring and Related Activities [Abstract]
Restructuring and acquisition charges	(12) Restructuring and Acquisition Charges There were $18.1 million and $20.8 million of Restructuring and acquisition charges included in Net income during the three and nine months ended September 30, 2015 . There were no Restructuring and acquisition charges included in Net income during the three months ended September 30, 2014 and we recognized $41.4 million of Restructuring and acquisition charges for the nine months ended September 30, 2014 . Included in Restructuring and acquisition charges for the three and nine months ended September 30, 2015 and nine months ended September 30, 2014 was $12.8 million and $34.5 million , respectively, related to the write-off of indemnification assets that arose from prior period acquisition activity. These charges were offset by the recognition of related previously unrecognized tax benefits of equal amounts in the provision for income taxes, and therefore had no impact on net income. The remaining $8.0 million of expense recognized during the nine months ended September 30, 2015 primarily consisted of (1) acquisition-related costs and (2) lease exit charges. The remaining $6.9 million of expense recognized during the nine months ended September 30, 2014 consisted of (1) severance, (2) lease exit fair value reserve adjustments, and (3) other acquisition and information technology integration costs. The following table shows the restructuring and acquisition accrual activity, exclusive of the $12.8 million and $34.5 million indemnification asset write-offs in 2015 and 2014, respectively, and the related payments made during the nine months ended September 30, 2015 and 2014 ($ in millions): Severance Retention Bonuses Lease Exit Other Acquisition Costs Total January 1, 2015 $ 3.0 — 4.2 0.4 $ 7.6 Accruals (0.1 ) — 0.2 7.9 8.0 Payments made (1.9 ) — (2.7 ) (4.5 ) (9.1 ) September 30, 2015 $ 1.0 — 1.7 3.8 $ 6.5 Severance Retention Lease Other Total January 1, 2014 $ 3.8 0.4 5.9 0.4 $ 10.5 Accruals 2.3 — 3.2 1.4 6.9 Payments made (5.2 ) — (3.7 ) (1.6 ) (10.5 ) September 30, 2014 $ 0.9 0.4 5.4 0.2 $ 6.9 We expect that the majority of accrued severance and other accrued acquisition costs will be paid during the fourth quarter of 2015. Lease exit payments are dependent on the terms of various leases, which extend as far out as 2018.

Subsequent Events [Abstract]
Subsequent Event	(14) Subsequent Events The Company announced on October 28, 2015, that its Board of Directors declared a semi-annual cash dividend of $0.29 per share of its common stock. The dividend payment will be made on December 15, 2015, to holders of record at the close of business on November 13, 2015. A dividend-equivalent in the same per share amount will also be paid simultaneously on outstanding but unvested shares of restricted stock units granted under the Company's Stock Award and Incentive Plan. On October 30, 2015, the Company closed on its previously announced acquisition of Oak Grove, now known as Jones Lang LaSalle Multifamily, LLC. The cash consideration payable by the Company's affiliates at closing was equal to $175.0 million from which Oak Grove retired outstanding indebtedness (excluding warehouse loans/lines) and redeemed its preferred unit holders. Oak Grove has the potential to earn future payments based on a five-year earn-out structure tied to performance of the combined platform such that total consideration payable could be up to $300.0 million . The expected total consideration payable pursuant to the Agreement and Plan of Merger is approximately $260.0 million . Refer to Note 5, Business Combinations, for additional details regarding this transaction. Subsequent to September 30, 2015, the Company also acquired Guardian Property Asset Management, the Dublin-based residential agency. The acquisition further expands JLL’s market-leading service offering in Ireland and continues the broader international expansion of its residential real estate services.

Revenue Recognition (Policies)

Revenue Recognition (Policies)	9 Months Ended

Revenue Recognition [Abstract]
Transactions commissions	We recognize transaction commissions related to leasing services and capital markets services as revenue when we provide the related services unless future contingencies exist.
Advisory and management fees	Advisory and management fees related to property and facility management services, valuation services, corporate property services, consulting services and investment management are recognized in the period in which we perform the related services.
Incentive fees	We recognize incentive fees in the period earned, based on the performance of funds' investments, contractual benchmarks and other contractual formulas. If future contingencies exist, we defer recognition of the related revenue until the respective contingencies have been satisfied.
Project and development management and construction management fees	We recognize project and development management and construction management fees by applying the percentage of completion method of accounting. The efforts expended method is used to determine the extent of progress towards completion for project and development management fees, and the costs incurred to total estimated costs method is used for construction management fees.
Gross and net accounting	Gross and Net Accounting: We follow the guidance of FASB Accounting Standards Codification ("ASC") 605-45, "Principal and Agent Considerations," when accounting for reimbursements received from clients. In certain of our businesses, primarily those involving management services, our clients reimburse us for expenses incurred on their behalf. We base the treatment of reimbursable expenses for financial reporting purposes upon the fee structure of the underlying contract. Accordingly, we report a contract that provides for fixed fees, fully inclusive of all personnel and other recoverable expenses, on a gross basis. When accounting on a gross basis, our reported revenue comprises the entire amount billed to our client and our reported expenses include all costs associated with the client. Certain contractual arrangements in our project and development services, including fit-out business activities and our facility management services, tend to have characteristics that result in accounting on a gross basis. In Note 4, Business Segments, for client assignments in property and facility management and in project and development services that are accounted for on a gross basis, we identify the gross contract costs, including vendor and subcontract costs ("gross contract costs"), and present separately their impact on both revenue and operating expenses in our RES segments. We exclude these gross contract costs from revenue and operating expenses in determining "fee revenue" and "fee-based operating expenses" in our segment presentation. We account for a contract on a net basis when the fee structure is comprised of at least two distinct elements, namely (1) a fixed management fee and (2) a separate component that allows for scheduled reimbursable personnel costs or other expenses to be billed directly to the client. When accounting on a net basis, we include the fixed management fee in reported revenue and net the reimbursement against expenses. We base this accounting on the following factors, which define us as an agent rather than a principal: • The property owner or client, with ultimate approval rights relating to the employment and compensation of on-site personnel, and bearing all of the economic costs of such personnel, is determined to be the primary obligor in the arrangement; • Reimbursement to JLL is generally completed simultaneously with payment of payroll or soon thereafter; • The property owner is contractually obligated to fund all operating costs of the property from existing cash flow or direct funding from its building operating account and JLL bears little or no credit risk; and • JLL generally earns no margin on the reimbursement aspect of the arrangement, obtaining reimbursement only for actual costs incurred. We account for the majority of our service contracts on a net basis. The reimbursable costs associated with these net contracts aggregated approximately $499.2 million and $465.4 million for the three months ended September 30, 2015 and 2014 , respectively, and $1.5 billion and $1.4 billion for the nine months ended September 30, 2015 and 2014 , respectively. The presentation of expenses pursuant to these arrangements under either a gross or net basis has no impact on operating income, net income or cash flows. Contracts accounted for on a gross basis resulted in certain costs reflected in revenue and operating expenses (gross contract costs) of $214.0 million and $185.4 million for the three months ended September 30, 2015 and 2014 , respectively, and $580.0 million and $536.3 million for the nine months ended September 30, 2015 and 2014 , respectively.
