	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, 2013, which are included in our 2013 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 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 2013 Annual Report on Form 10-K for further discussion of our significant accounting policies and estimates.

Interim Information	'
	-1	Interim Information
	Our Consolidated Financial Statements as of March 31, 2014, and for the three months ended March 31, 2014 and 2013, are unaudited; however, 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 for 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 benefit expense from period to period. Non-variable operating expenses, which we treat as expenses when they are 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 the impact of tax planning activities. Significant changes in the geographic mix of income can greatly impact our estimated effective tax rate.
	As a result of the items mentioned above, the results for the three months ended March 31, 2014 and 2013, are not indicative of what our results will be for the full fiscal year.

	In July 2013, the FASB issued ASU 2013-11, "Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward or a Tax Credit Carryforward Exists," which provides guidance for the financial statement presentation of such unrecognized tax benefits. ASU 2013-11 became effective for us on January 1, 2014, and resulted in the reclassification of $11.1 million of unrecognized tax benefits as a reduction of our deferred tax assets previously classified as a current taxes payable within Accounts payable and accrued liabilities relating to net operating loss carryforwards.

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 service 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.
	Certain construction management fees, which are gross construction services revenue reported net of subcontract costs, were $1.2 million and $1.7 million for the three months ended March 31, 2014 and 2013, respectively. Gross construction services revenue totaled $27.5 million and $41.2 million for the three months ended March 31, 2014 and 2013, respectively, and subcontract costs totaled $26.3 million and $39.5 million for the three months ended March 31, 2014 and 2013, respectively.
	We include costs in excess of billings on uncompleted construction contracts of $3.3 million and $4.4 million in Trade receivables, and billings in excess of costs on uncompleted construction contracts of $5.8 million and $7.4 million, in Deferred income, as of March 31, 2014 and December 31, 2013, respectively.
	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 includes the full billing 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 expense in our Real Estate Services ("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, JLL bears little or no credit risk; and
	•	JLL generally earns no margin in 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. These net costs aggregated approximately $478.9 million and $423.7 million for the three months ended March 31, 2014 and 2013, 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 $159.6 million and $75.5 million for the three months ended March 31, 2014, and 2013, respectively.

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 be services provided to non-occupying property investors and "facilities management" to be 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. We allocate these corporate global overhead expenses to the business segments based on the budgeted operating expenses of each segment.
	For segment reporting, we show revenue net of gross contract costs in our RES segments. Excluding these costs from revenue and expenses in a "net" presentation of "fee revenue" and "fee-based operating expense" more accurately reflects how we manage our expense base and operating margins. See Note 3, Revenue Recognition, for additional information on our gross and net accounting policies. For segment reporting we also show 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 also excludes Restructuring and acquisition costs. These amounts relate to the presentation of revenue and associated expense and have an insignificant impact on previously reported operating income.
	The Chief Operating Decision Maker of JLL measures the segment results net of gross contract costs, with Equity earnings from real estate ventures, and without Restructuring and acquisition charges. We define the Chief Operating Decision Maker collectively as our Global Executive Board, which is comprised of our Global Chief Executive Officer, Global Chief Financial Officer and the Chief Executive Officers of each of our reporting segments.

	During the three months ended March 31, 2014, we paid a total of $9.2 million for business acquisitions consisting of the purchase of a portion of the minority ownership in our Indian operations for which we had previously recorded a minority shareholder redemption liability on the balance sheet and one new acquisition. We also paid $1.4 million for deferred acquisition and earn-out obligations for acquisitions completed in prior years.
	Earn-Out Payments
	At March 31, 2014, we had the potential to make earn-out payments on 13 acquisitions that are subject to the achievement of certain performance conditions. The maximum amount of the potential earn-out payments for these acquisitions was $32.3 million at March 31, 2014. 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 have $1.9 billion of unamortized intangibles and goodwill at March 31, 2014. A significant portion of these unamortized intangibles and goodwill 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 intangible and goodwill balances. The $1.9 billion of unamortized intangibles and goodwill consists of: (1) goodwill of $1.9 billion with indefinite useful lives which is not amortized, (2) identifiable intangibles of $35.7 million that will be amortized over their remaining finite useful lives, and (3) $7.9 million of identifiable intangibles with indefinite useful lives that is not amortized.

Investments in Real Estate Ventures	'
	-6	Investments in Real Estate Ventures
	As of March 31, 2014 and December 31, 2013, we had Investments in real estate ventures of $291.8 million and $287.2 million, respectively. We account for the majority of our investments in real estate ventures under the equity method of accounting. We have elected the fair value option for certain of our direct investments. 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 generally range from less than 1% to 15%.
	We utilize two investment vehicles, LaSalle Investment Company I ("LIC I") and LaSalle Investment Company II ("LIC II"), to facilitate the majority of our co-investment activity when we do not invest directly into a real estate venture. LIC I and LIC II invest in certain real estate ventures that own and operate commercial real estate. We have an effective 47.85% ownership interest in LIC I, and an effective 48.78% ownership interest in LIC II; primarily institutional investors hold the remaining 52.15% and 51.22% interests in LIC I and LIC II, respectively.
	At March 31, 2014, LIC II has unfunded capital commitments to the underlying funds of $185.0 million and a $30.0 million revolving credit facility (the "LIC II Facility"), principally for working capital needs. At March 31, 2014, our maximum potential unfunded commitments to LIC I and LIC II combined were $123.3 million which include our share of commitments to underlying funds and our exposure to funding our proportionate share of the then outstanding balance on the LIC II Facility. LIC I's and LIC II's exposures to liabilities and losses of the ventures are limited to their existing capital contributions and remaining capital commitments. Our unfunded commitment to LIC I will remain in effect until December 31, 2014. We expect that LIC II will draw down on our commitment over the next three to five years to satisfy its existing commitments to underlying funds.
	The following table summarizes the discussion above relative to LIC I and LIC II at March 31, 2014 ($ in millions):
		LIC I			LIC II
	Our effective ownership interest in co-investment vehicle	47.85		%	48.78		%
	Our maximum potential unfunded commitments	$	5.1		$	118.2
	Our share of unfunded capital commitments to underlying funds	0.4			90.2
	Our maximum exposure assuming facilities are fully drawn	N/A			14.6
	Our share of exposure on outstanding borrowings	N/A			6.5
	Exclusive of our LIC I and LIC II commitment structures, we have other potential unfunded commitment obligations, the maximum of which is $81.4 million as of March 31, 2014.
	Our investments in real estate ventures include investments in entities classified as variable interest entities ("VIEs") that we analyze for potential consolidation. We had investments, either directly or indirectly, of $4.9 million and $2.6 million at March 31, 2014 and December 31, 2013, respectively, in entities classified as VIEs. We evaluate each of these VIEs to determine whether we might have the power to direct the activities that most significantly impact the entity's economic performance. In certain circumstances, we have determined that we either did not have the power to direct the key activities, or shared power with investors, lenders, or other actively-involved third parties. Additionally, our exposure to loss is limited to our investment in the VIEs. Therefore, we concluded that we would not be deemed to have a controlling financial interest in or be the primary beneficiary of these VIEs and therefore do not consolidate them in our Consolidated Financial Statements. In other circumstances, we have determined we are the primary beneficiary of certain other VIEs and accordingly, consolidate such entities. The assets of the consolidated VIEs are available only for the settlement of the obligations of the respective entities. The mortgage loans of the consolidated VIEs are non-recourse to JLL.
	Summarized balance sheets for our consolidated VIEs as of March 31, 2014 and December 31, 2013 are as follows ($ in thousands):
		31-Mar-14				31-Dec-13
	Property and equipment, net	$	31,999			14,389

	Operating and other expenses	(418		)		(60	)
	Net income	$	85			227
	The members' equity and net income of the consolidated VIEs are allocated in total to the noncontrolling interest holders as Noncontrolling interest on our Consolidated Balance Sheets and as Net income attributable to noncontrolling interest in our Consolidated Statements of Comprehensive Income.
	Impairment
	We review investments in real estate accounted for under the equity method on a quarterly basis for indications of whether we may not be able to recover the carrying value of the real estate assets underlying our investments in real estate ventures and whether our investments are other than temporarily impaired. Our judgments regarding the existence of impairment indicators 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, with regard to each underlying asset and investment. Future events could occur which would cause us to conclude that impairment indicators exist and an impairment loss is warranted. When events or changes in circumstances indicate that the carrying amount of the real estate asset underlying one of our investments in real estate ventures may be impaired, we review the recoverability of the carrying amount of the real estate asset in comparison to an estimate of the future undiscounted cash flows expected to be generated by the underlying asset.
	When the carrying amount of the real estate asset is in excess of the future undiscounted cash flows, we use a discounted cash flow approach that primarily uses Level 3 inputs to determine the fair value of the asset to compute the amount of the potential impairment. Equity earnings from real estate ventures included impairment charges of $0.8 million and $1.7 million, for the three months ended March 31, 2014 and 2013, respectively, representing our share of the impairment charges against individual assets held by our real estate ventures. We did not recognize any impairment charges related to our equity investments during either of the three months ended March 31, 2014 and 2013.
	Fair Value
	We elected the fair value option for certain investments in real estate ventures, in the ordinary course of business at the time of the initial direct investment, because we believe the fair value accounting method more accurately represents the value and performance of these investments. At March 31, 2014 and December 31, 2013, we had $80.7 million and $78.9 million, respectively, of investments that were accounted for under the fair value method. For investments in real estate ventures for which the fair value option has been elected, we increase or decrease our investment each reporting period by the change in the fair value of these investments. We reflect these fair value adjustments as gains or losses in our Consolidated Statements of Comprehensive Income within Equity earnings from real estate ventures. The fair value of these investments is based on discounted cash flow models and other assumptions that reflect our outlook for the commercial real estate market relative to these real estate assets and is primarily based on inputs that are Level 3 inputs in the fair value hierarchy.
	The following table shows the movements in our investments in real estate ventures that are accounted for under the fair value accounting method ($ in thousands):
		2014			2013
	Balances as of January 1,	$	78,941		63,579

	Foreign currency translation adjustments, net	(154		)	207
	Balances as of March 31,	$	80,695		62,824
	We account for our investment in LIC II under the equity method of accounting. LIC II accounts for certain of its investments under the fair value method. LIC II had investments of $55.1 million and $51.1 million, at March 31, 2014 and December 31, 2013, respectively, that were accounted for under the fair value method.

	Unvested shares expected to vest	1,408.00		$	71.01	2.09
	We determine the fair value of restricted stock units based on the market price of the Company's common stock on the grant date. As of March 31, 2014, we had $37.7 million of remaining unamortized deferred compensation related to unvested restricted stock units. We will recognize the remaining cost of unvested restricted stock units outstanding at March 31, 2014 over varying periods into 2019.
	Shares vested during the three months ended March 31, 2014 and 2013, had grant date fair values of $7.5 million and $2.7 million, respectively. Shares granted during the three months ended March 31, 2014 and 2013, had grant date fair values of $16.0 million and $14.5 million, respectively.
	Other Stock Compensation Programs
	We also have 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 three months ended March 31, 2014 and 2013. The fair value of options granted under the SAYE plan are amortized over their respective vesting periods. There were approximately 219,200 and 227,800 options outstanding under the SAYE plan at March 31, 2014 and December 31, 2013, respectively.

	For each of the three months ended March 31, 2014 and 2013, we made payments of $3.5 million to these plans. We expect to contribute an additional $9.8 million to these plans in the last nine months of 2014, for a total of $13.3 million in 2014. We made $13.2 million of contributions to these plans during the year ended December 31, 2013.

Fair Value Measurements	'
	-9	Fair Value Measurements
	ASC 820, "Fair Value Measurements and Disclosures," establishes a framework for measuring fair value and establishes 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 of the three months ended March 31, 2014 or 2013.
	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 due to their variable interest rate terms and market spreads.
	We estimate that the fair value of our Long-term senior notes was $270.4 million and $262.6 million at March 31, 2014 and December 31, 2013, respectively, using dealer quotes that are Level 2 inputs in the fair value hierarchy. The carrying value of our Long-term senior notes was $275.0 million at March 31, 2014 and December 31, 2013.
	We record Warehouse receivables at the lower of cost or fair value based on the commitment price, in accordance with ASC Topic 948, Financial Services-Mortgage Banking. The fair values of our Warehouse receivables are based on the committed purchase price. When applicable, we determine the fair value of Warehouse receivables based on readily observable Level 2 inputs.
	Recurring Fair Value Measurements
	The following table categorizes by level in the fair value hierarchy our assets and liabilities that are measured at fair value on a recurring basis at March 31, 2014 and December 31, 2013 ($ in thousands):
			31-Mar-14			31-Dec-13
			Level 2		Level 3	Level 2		Level 3

		Deferred compensation plan liabilities	93,455		—	85,853		—
	Total liabilities at fair value		$	96,582	—	$	98,947	—
	We regularly use foreign currency forward contracts to manage our currency exchange rate risk related to intercompany lending and cash management practices. We determined 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 March 31, 2014, these forward exchange contracts had a gross notional value of $2.0 billion ($959.6 million on a net basis) and were recorded on our Consolidated Balance Sheet as a current asset of $10.3 million and a current liability of $3.1 million. At December 31, 2013, these forward exchange contracts had a gross notional value of $1.96 billion ($1.01 billion on a net basis) and were recorded on our Consolidated Balance Sheet as a current asset of $13.0 million and a current liability of $13.1 million.
	The revaluations of our foreign currency forward contracts resulted in net gains of $7.2 million and $1.5 million for the three months ended March 31, 2014 and 2013, 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 months ended March 31, 2014 or 2013.
	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 $10.3 million asset at March 31, 2014 was comprised of gross contracts with receivable positions of $11.0 million and payable positions of $0.7 million. The $3.1 million liability position at March 31, 2014 was comprised of gross contracts with receivable positions of $0.7 million and payable positions of $3.8 million. At December 31, 2013, the $13.0 million asset was comprised of gross contracts with receivable positions of $13.8 million and payable positions of $0.8 million. The $13.1 million liability position at December 31, 2013, was comprised of gross contracts with receivable positions of $1.3 million and payable positions of $14.4 million.
	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 is recorded on our Consolidated Balance Sheet at March 31, 2014, as Other long-term assets of $92.8 million, long-term Deferred compensation liabilities of $93.5 million, and as a reduction of equity, Shares held in trust, of $8.1 million. This plan is recorded on our Consolidated Balance Sheet at December 31, 2013 as Other long-term assets of $85.1 million, long-term Deferred compensation liabilities of $85.9 million, and as a reduction of equity, Shares held in trust, of $8.1 million.
	We have elected the fair value option for certain direct investments in real estate ventures. We had $80.7 million and $78.9 million at March 31, 2014 and December 31, 2013, respectively, of direct investments in real estate ventures that were accounted for under the fair value method. For these fair value 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 reflected as gains or losses in our Consolidated Statements of Comprehensive Income within Equity earnings from real estate ventures. We determine the fair value of these investments based on discounted cash flow models that use Level 3 assumptions that reflect our outlook for the commercial real estate market relative to these real estate assets. See Note 6, Investments in Real Estate Ventures, for additional information regarding our investments accounted for under the fair value method.
	Non-Recurring Fair Value Measurements
	We review our Investments in real estate ventures accounted for under the equity method on a quarterly basis for indications of whether we may not be able to recover the carrying value of the real estate assets underlying our investments and whether our investments are other than temporarily impaired. When the carrying amount of the underlying real estate asset is in excess of the future undiscounted cash flows, we use a discounted cash flow approach to determine the fair value of the asset in computing the amount of the impairment. Our determination of fair value is based on a discounted cash flow approach using primarily Level 3 inputs. See Note 6, Investments in Real Estate Ventures, for additional information regarding our investments accounted for under the equity method.

	Credit Facility
	We have a $1.2 billion unsecured revolving credit facility (the "Facility") that matures in 2018. We had $443.0 million and $155.0 million outstanding under the Facility at March 31, 2014 and December 31, 2013, respectively. Under our current Facility, at March 31, 2014, we had the capacity to borrow up to an additional $734.4 million. The average outstanding borrowings under the Facility were $274.7 million and $304.9 million during the three months ended March 31, 2014 and 2013, respectively.
	The pricing on the Facility ranges from LIBOR plus 1.00% to 1.75%. As of March 31, 2014, pricing on the Facility was LIBOR plus 1.00%. The effective interest rate on our debt was 1.3% and 1.4% for the three months ended March 31, 2014 and 2013, respectively.
	We remain in compliance with all covenants under our Facility as of March 31, 2014. The Facility requires us to maintain a leverage ratio that does not exceed 3.50 to 1 and a minimum cash interest coverage ratio of 3.00 to 1.
	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 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 working capital needs (including payment of accrued incentive compensation), co-investment activities, dividend payments, share repurchases, capital expenditures and business acquisitions.
	Short-Term Borrowings
	In addition to our Facility, we have the capacity to borrow up to an additional $46.4 million under local overdraft facilities. We had short-term borrowings (including capital lease obligations and local overdraft facilities) of $16.8 million and $24.5 million at March 31, 2014 and December 31, 2013, respectively, of which $12.7 million and $22.8 million at March 31, 2014 and December 31, 2013, 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.

	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 captive insurance company), 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 when probable and estimable. The accrual for professional indemnity insurance claims facilitated through our captive insurance company, which relates to multiple years, was $5.7 million and $6.2 million as of March 31, 2014 and December 31, 2013, respectively.

	-12	Restructuring and Acquisition Charges
	For the three months ended March 31, 2014, we recognized $36.0 million of Restructuring and acquisition charges, of which $34.5 million related to the write-off of an indemnification asset that arose from prior period acquisition activity; this write-off was offset by the recognition of a related previously unrecognized tax benefit of an equal amount in the provision for income taxes, and therefore had no impact on net income. The remaining $1.4 million of expense consisted of (1) severance, (2) lease exit fair value reserve adjustments, and (3) other acquisition and information technology integration costs. For the three months ended March 31, 2013, we recognized $3.2 million of expense consisting of (1) severance, (2) King Sturge employee retention bonuses, and (3) other acquisition and information technology integration costs.
	The following table shows the restructuring and acquisition accrual activity, exclusive of the $34.5 million indemnification asset write-off, and the related payments made during the three months ended March 31, 2014 and 2013 ($ in thousands):

	We expect that the majority of accrued severance, accrued retention bonuses, and other accrued acquisition costs will be paid during 2014. Lease exit payments are dependent on the terms of various leases, which extend into 2017.

Revenue Recognition [Abstract]	'
Transactions commissions	'
	We recognize transaction commissions related to leasing services and capital markets services as revenue when we provide the related service 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.
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.
	Certain construction management fees, which are gross construction services revenue reported net of subcontract costs, were $1.2 million and $1.7 million for the three months ended March 31, 2014 and 2013, respectively. Gross construction services revenue totaled $27.5 million and $41.2 million for the three months ended March 31, 2014 and 2013, respectively, and subcontract costs totaled $26.3 million and $39.5 million for the three months ended March 31, 2014 and 2013, respectively.
	We include costs in excess of billings on uncompleted construction contracts of $3.3 million and $4.4 million in Trade receivables, and billings in excess of costs on uncompleted construction contracts of $5.8 million and $7.4 million, in Deferred income, as of March 31, 2014 and December 31, 2013, respectively.
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 includes the full billing 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 expense in our Real Estate Services ("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, JLL bears little or no credit risk; and
	•	JLL generally earns no margin in 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. These net costs aggregated approximately $478.9 million and $423.7 million for the three months ended March 31, 2014 and 2013, 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 $159.6 million and $75.5 million for the three months ended March 31, 2014, and 2013, respectively.
