Summary of Significant Accounting Policies | 1. Summary of Significant Accounting Policies Terms Used in Notes to Consolidated Financial Statements ASC ASC Topic 606 No. 2014-09, ASU FASB GAAP - IRC IRS Underwriting enterprises VIE Nature of Operations Arthur J. Gallagher & Co. and its subsidiaries, collectively referred to herein as we, our, us or the company, provide insurance brokerage, consulting and third party claims settlement and administration services to both domestic and international entities through three reportable operating segments. Our brokers, agents and administrators act as intermediaries between underwriting enterprises and our clients. Our brokerage segment operations provide brokerage and consulting services to companies and entities of all types, including commercial, not-for-profit, not-for-profit, Chem-Mod We do not assume underwriting risk on a net basis, other than with respect to de minimis amounts necessary to provide minimum or regulatory capital amounts to organize captives, pools, specialized underwriters or risk-retention groups. Rather, capital necessary for events of loss coverages is provided by underwriting enterprises. Investment income and other revenues are generated from our premium financing operations and our investment portfolio, which includes our invested cash and restricted cash we hold on behalf of our clients, as well as clean energy investments. We are headquartered in Rolling Meadows, Illinois, have operations in 32 countries and offer client-service capabilities in more than 150 countries globally through a network of correspondent insurance brokers and consultants. Basis of Presentation The accompanying consolidated financial statements include our accounts and all of our majority-owned subsidiaries (50% or greater ownership). Substantially all of our investments in partially owned entities in which our ownership is less than 50% are accounted for using the equity method based on the legal form of our ownership interest and the applicable ownership percentage of the entity. However, in situations where a less than 50%-owned investment has been determined to be a VIE and we are deemed to be the primary beneficiary in accordance with the variable interest model of consolidation, we will consolidate the investment into our consolidated financial statements. For partially owned entities accounted for using the equity method, our share of the net earnings of these entities is included in consolidated net earnings. All material intercompany accounts and transactions have been eliminated in consolidation. In the preparation of our consolidated financial statements as of December 31, 2017, management evaluated all material subsequent events or transactions that occurred after the balance sheet date through the date on which the financial statements were issued for potential recognition in our consolidated financial statements and/or disclosure in the notes thereto. Use of Estimates The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These accounting principles require us to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues and expenses, and the disclosure of contingent assets and liabilities at the date of our consolidated financial statements. We are also required to make certain judgments and estimates that affect the disclosed amounts of revenues and expenses related to the potential impact of the adoption of and future accounting under ASC Topic 606. We periodically evaluate our estimates and assumptions, including those relating to the valuation of goodwill and other intangible assets, investments (including our IRC Section 45 investments), income taxes, stock-based compensation, claims handling obligations, retirement plans, litigation and contingencies. We base our estimates on historical experience and various assumptions that we believe to be reasonable based on specific circumstances. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein. Revenue Recognition Our revenues are derived from commissions and fees as primarily specified in a written contract, or unwritten business understanding, with our clients or underwriting enterprises. We also recognize investment income over time from our invested assets and invested assets we hold on behalf of our clients or underwriting enterprises. Brokerage segment Our brokerage segment generates revenues by: (i) Identifying, negotiating and placing all forms of insurance or reinsurance coverages, as well as providing risk-shifting, risk-sharing and risk-mitigation consulting services, principally related to property/casualty, life, health, welfare and disability insurance. We also provide these services through, or in conjunction with, other unrelated agents and brokers, consultants and management advisors. (ii) Acting as an agent or broker for multiple underwriting enterprises by providing services such as sales, marketing, selecting, negotiating, underwriting, servicing and placing insurance coverage on their behalf. (iii) Providing consulting services related to health and welfare benefits, voluntary benefits, executive benefits, compensation, retirement planning, institutional investment and fiduciary, actuarial, compliance, private insurance exchange, human resource technology, communications, and benefits administration. (iv) Providing management and administrative services to captives, pools, risk-retention groups, healthcare exchanges, small underwriting enterprises, such as accounting, claims and loss processing assistance, feasibility studies, actuarial studies, data analytics and other administrative services. The vast majority of our brokerage contracts and service understandings are for a period of one year or less. Commissions and fees The primary source of brokerage segment revenues are commissions from underwriting enterprises, which are based on a percentage of premiums paid by our clients, or fees received from clients, which are based on an agreed level of service with our clients, usually in lieu of commissions. Commissions are fixed at the contract effective date and generally are based on a percentage of premiums for insurance coverage or employee head count for employer sponsored benefit plans. Commissions depend upon a large number of factors, including the type of risk being placed, the particular underwriting enterprise’s demand, the expected loss experience of the particular risk of coverage, and historical benchmarks surrounding the level of effort necessary for us to place and service the insurance contract. Fees are rarely tied to the amount of premiums; instead, they are based on an expected level of effort to provide our services. We recognize commission and fee revenues at the later of the billing or the effective date of the related insurance policies, net of an allowance for estimated policy cancellations. We recognize commission revenues related to installment premiums as the installments are billed. We recognize commissions on premiums directly billed by underwriting enterprises as revenue when we have obtained the data necessary to reasonably determine such amounts. Historically, we have not been able to reasonably determine these types of commission revenues until we have received the cash or the related policy detail or other specific information from the underwriting enterprise. Commissions on premiums billed directly by underwriting enterprises to the insureds generally relate to: (i) a large number of property/casualty insurance policy transactions, each with small premiums, and (ii) the number of enrolled employees in employer sponsored plans in our employee benefit brokerage operations. Under these direct bill arrangements, the underwriting enterprise controls the entire billing and policy issuance process. We record the income effects of subsequent premium adjustments when the adjustments become known. Fee revenues generated from the brokerage segment primarily relate to fees negotiated in lieu of commissions that we recognize in the same manner as commission revenues. We recognize these fee revenues ratably as the services are rendered, and record the income effects of subsequent fee adjustments when the adjustments become known. For consulting and advisory services, we recognize our revenue in the period in which we provide the service or advice. For management and administrative services, our revenue is recognized ratably over the contract period consistent with the performance of our obligations, mostly over an annual term. Supplemental revenues Certain underwriting enterprises may pay us additional revenues based on the volume of premium we place with them and for insights into our sales pipeline, our sales capabilities or our risk selection knowledge. These amounts are in excess of the commission and fee revenues discussed above, and not all business we place with underwriting enterprises is eligible for supplemental revenues. Unlike contingent revenues, discussed below, these revenues are a fixed amount or fixed percent of premium of the underlying eligible insurance contracts. We recognize supplemental revenues using internal data and information received from underwriting enterprises that allows us to reasonably estimate the supplemental revenues earned in the period. Contingent revenues Certain underwriting enterprises may pay us additional revenues for our sales capabilities, our risk selection knowledge, or our administrative efficiencies. These amounts are in excess of the commission revenues discussed above, and not all business we place with participating underwriting enterprises is eligible for contingent revenues. Unlike supplemental revenues, discussed above, these revenues are variable, generally based on growth, the loss experience of the underlying insurance contracts, and/or our efficiency in processing the business. We generally operate under calendar year contracts, but we do not receive these contingent revenues from the underwriting enterprises until the following calendar year, generally in the first and second quarters, after verification of the performance indicators outlined in the contracts. We recognize contingent revenues as revenue when we have obtained the data necessary to reasonably determine such amounts. Historically we have not been able to reasonably determine these types of revenues until we have received the cash or the related policy detail or other underwriting enterprise specific information from the underwriting enterprise. Sub-brokerage Sub-brokerage revenues. Sub-brokerage sub-brokers Risk Management segment Revenues for our risk management segment are comprised of fees generally negotiated (i) on a per-claim cost-plus Per-claim Where we operate under a contract where our fee is established on a per-claim Cost-plus fees Where we provide services and generate revenues on a cost-plus basis, we recognize revenue over the contract period. Performance-based fees Certain clients pay us additional fee revenues for our efficiency in managing claims or on the basis of claim outcome effectiveness. These amounts are in excess of the fee revenues discussed above. These revenues are variable, generally based on various performance metrics of the underlying contracts. We generally operate under multi-year contracts with fiscal year measurement periods. We do not receive these fees, if earned, until the following year after verification of the performance metrics outlined in the contracts. Each period we base our estimates on a contract-by-contract Investment income Investment income primarily includes interest and dividend income (including interest income from our premium financing operations), which is accrued as it is earned. Gains on books of business sales represent one-time Claims Handling Obligations We are obligated under certain circumstances to provide future claims handling and certain administrative services for our former global risks brokerage clients in the U.K. Our obligation is the result of following the industry practice of insurance brokers providing future claims handling and administrative services to former clients. In addition, under certain circumstances, our risk management segment operations are contractually obligated to provide contract claim settlement and administration services to our former clients. Accordingly, we record a liability for these deferred run-off Earnings per Share Basic net earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding during the reporting period. Diluted net earnings per share is computed by dividing net earnings by the weighted average number of common and common equivalent shares outstanding during the reporting period. Common equivalent shares include incremental shares from dilutive stock options, which are calculated from the date of grant under the treasury stock method using the average market price for the period. Cash and Cash Equivalents Short-term investments, consisting principally of cash and money market accounts that have average maturities of 90 days or less, are considered cash equivalents. Restricted Cash In our capacity as an insurance broker, we collect premiums from insureds and, after deducting our commissions and/or fees, remit these premiums to underwriting enterprises. We hold unremitted insurance premiums in a fiduciary capacity until we disburse them, and the use of such funds is restricted by laws in certain states and foreign jurisdictions in which our subsidiaries operate. Various state and foreign agencies regulate insurance brokers and provide specific requirements that limit the type of investments that may be made with such funds. Accordingly, we invest these funds in cash and U.S. Treasury fund accounts. We can earn interest income on these unremitted funds, which is included in investment income in the accompanying consolidated statement of earnings. These unremitted amounts are reported as restricted cash in the accompanying consolidated balance sheet, with the related liability reported as premiums payable to underwriting enterprises. Additionally, several of our foreign subsidiaries are required by various foreign agencies to meet certain liquidity and solvency requirements. We were in compliance with these requirements at December 31, 2017. Related to our third party administration business and in certain of our brokerage operations, we are responsible for client claim funds that we hold in a fiduciary capacity. We do not earn any interest income on the funds held. These client funds have been included in restricted cash, along with a corresponding liability in premiums payable to underwriting enterprises in the accompanying consolidated balance sheet. Premiums and fees receivable Premiums and fees receivable in the accompanying consolidated balance sheet are net of allowances for estimated policy cancellations and doubtful accounts. The allowance for estimated policy cancellations was $7.4 million and $7.1 million at December 31, 2017 and 2016, respectively, which represents a reserve for future reversals in commission and fee revenues related to the potential cancellation of client insurance policies that were in force as of each year end. The allowance for doubtful accounts was $13.5 million and $12.8 million at December 31, 2017 and 2016, respectively. We establish the allowance for estimated policy cancellations through a charge to revenues and the allowance for doubtful accounts through a charge to operating expenses. Both of these allowances are based on estimates and assumptions using historical data to project future experience. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein. We periodically review the adequacy of these allowances and make adjustments as necessary. Derivative Instruments We are exposed to market risks, including changes in foreign currency exchange rates and interest rates. To manage the risk related to these exposures, we enter into various derivative instruments that reduce these risks by creating offsetting exposures In the normal course of business, we are exposed to the impact of foreign currency fluctuations that impact our results of operations and cash flows. We utilize a foreign currency risk management program involving foreign currency derivatives that consist of several monthly put/call options designed to hedge a portion of our future foreign currency disbursements through various future payment dates. To mitigate the counterparty credit risk we only enter into contracts with major financial institutions based upon their credit ratings and other factors. These derivative instrument contracts are cash flow hedges that qualify for hedge accounting and primarily hedge against fluctuations between changes in the GBP and Indian Rupee versus the U.S. dollar. Changes in fair value of the derivative instruments are reflected in other comprehensive earnings in the accompanying consolidated balance sheet. The impact of the hedge at maturity is recognized in the income statement as a component of investment income, compensation and operating expenses depending on the nature of the hedged item. We enter into various long term debt agreements. We use interest rate derivatives, typically swaps, to reduce our exposure to the effects of interest rate fluctuations on the forecasted interest rates for up to two years into the future. These derivative instrument contracts are periodically monitored for hedge ineffectiveness, the amount of which has not been material to the accompanying consolidated financial statements. We do not use derivatives for trading or speculative purposes. Premium Financing Seven subsidiaries of the brokerage segment make short-term loans (generally with terms of twelve months or less) to our clients to finance premiums. These premium financing contracts are structured to minimize potential bad debt expense to us. Such receivables are generally considered delinquent after seven days of the payment due date. In normal course, insurance policies are cancelled within one month of the contractual payment due date if the payment remains delinquent. We recognize interest income as it is earned over the life of the contract using the “level-yield” method. Unearned interest related to contracts receivable is included in the receivable balance in the accompanying consolidated balance sheet. The outstanding loan receivable balance was $305.5 million and $241.2 million at December 31, 2017 and 2016, respectively. Fixed Assets We carry fixed assets at cost, less accumulated depreciation, in the accompanying consolidated balance sheet. We periodically review long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying value of the assets may not be recoverable. Under those circumstances, if the fair value were less than the carrying amount of the asset, we would recognize a loss for the difference. Depreciation for fixed assets is computed using the straight-line method over the following estimated useful lives: Useful Life Office equipment Three to ten years Furniture and fixtures Three to ten years Computer equipment Three to five years Building Fifteen to forty years Software Three to five years Refined fuel plants Ten years Leasehold improvements Shorter of the lease term or useful life of the asset Intangible Assets Intangible assets represent the excess of cost over the estimated fair value of net tangible assets of acquired businesses. Our primary intangible assets are classified as either goodwill, expiration lists, non-compete non-compete non-compete non-compete We review all of our intangible assets for impairment periodically (at least annually for goodwill) and whenever events or changes in business circumstances indicate that the carrying value of the assets may not be recoverable. We perform such impairment reviews at the division (i.e., reporting unit) level with respect to goodwill and at the business unit level for amortizable intangible assets. In reviewing intangible assets, if the fair value were less than the carrying amount of the respective (or underlying) asset, an indicator of impairment would exist and further analysis would be required to determine whether or not a loss would need to be charged against current period earnings as a component of amortization expense. Based on the results of impairment reviews in 2017, 2016 and 2015, we wrote off $6.2 million, $1.8 million and $11.5 million, respectively, of amortizable intangible assets primarily related to prior year acquisitions of our brokerage segment, which is included in amortization expense in the accompanying consolidated statement of earnings. The determinations of impairment indicators and fair value are based on estimates and assumptions related to the amount and timing of future cash flows and future interest rates. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein. Income Taxes Our tax rate reflects the statutory tax rates applicable to our taxable earnings and tax planning in the various jurisdictions in which we operate. Significant judgment is required in determining the annual effective tax rate and in evaluating uncertain tax positions. We report a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in our tax return. We evaluate our tax positions using a two-step Uncertain tax positions are measured based upon the facts and circumstances that exist at each reporting period and involve significant management judgment. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue. We recognize interest and penalties, if any, related to unrecognized tax benefits in our provision for income taxes. Tax law requires certain items to be included in our tax returns at different times than such items are reflected in the financial statements. As a result, the annual tax expense reflected in our consolidated statements of earnings is different than that reported in our tax returns. Some of these differences are permanent, such as expenses that are not deductible in our tax returns, and some differences are temporary and reverse over time, such as depreciation expense and amortization expense deductible for income tax purposes. Temporary differences create deferred tax assets and liabilities. Deferred tax liabilities generally represent tax expense recognized in the financial statements for which a tax payment has been deferred, or expense which has been deducted in the tax return but has not yet been recognized in the financial statements. Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns in future years for which a benefit has already been recorded in the financial statements. We establish or adjust valuation allowances for deferred tax assets when we estimate that it is more likely than not that future taxable income will be insufficient to fully use a deduction or credit in a specific jurisdiction. In assessing the need for the recognition of a valuation allowance for deferred tax assets, we consider whether it is more likely than not that some portion, or all, of the deferred tax assets will not be realized and adjust the valuation allowance accordingly. We evaluate all significant available positive and negative evidence as part of our analysis. Negative evidence includes the existence of losses in recent years. Positive evidence includes the forecast of future taxable income by jurisdiction, tax-planning Fair Value of Financial Instruments Fair value accounting establishes a framework for measuring fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). This framework includes a fair value hierarchy that prioritizes the inputs to the valuation technique used to measure fair value. The classification of a financial instrument within the valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels of the hierarchy in order of priority of inputs to the valuation technique are defined as follows: • Level 1 - Valuations are based on unadjusted quoted prices in active markets for identical financial instruments; • Level 2 - Valuations are based on quoted market prices, other than quoted prices included in Level 1, in markets that are not active or on inputs that are observable either directly or indirectly for the full term of the financial instrument; and • Level 3 - Valuations are based on pricing or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management’s own assumptions about the assumptions a market participant would use in pricing the financial instrument. The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measure in its entirety. The carrying amounts of financial assets and liabilities reported in the accompanying consolidated balance sheet for cash and cash equivalents, restricted cash, premiums and fees receivable, premiums payable to underwriting enterprises, accrued salaries and bonuses, accounts payable and other accrued liabilities, unearned fees and income taxes payable, at December 31, 2017 and 2016, approximate fair value because of the short-term duration of these instruments. See Note 3 to these consolidated financial statements for the fair values related to the establishment of intangible assets and the establishment and adjustment of earnout payables. See Note 7 to these consolidated financial statements for the fair values related to borrowings outstanding at December 31, 2017 and 2016 under our debt agreements. See Note 12 to these consolidated financial statements for the fair values related to investments at December 31, 2017 and 2016 under our defined benefit pension plan. Litigation We are the defendant in various legal actions related to claims, lawsuits and proceedings incident to the nature of our business. We record liabilities for loss contingencies, including legal costs (such as fees and expenses of external lawyers and other service providers) to be incurred, when it is probable that a liability has been incurred on or before the balance sheet date and the amount of the liability can be reasonably estimated. We do not discount such contingent liabilities. To the extent recovery of such losses and legal costs is probable under our insurance programs, we record estimated recoveries concurrently with the losses recognized. Significant management judgment is required to estimate the amounts of such contingent liabilities and the related insurance recoveries. In order to assess our potential liability, we analyze our litigation exposure based on available information, including consultation with outside counsel handling the defense of these matters. As these liabilities are uncertain by their nature, the recorded amounts may change due to a variety of different factors, including new developments in, or changes in approach, such as changing the settlement strategy as applicable to each matter. Retention bonus arrangements In connection with the hiring and retention of both new talent and experienced personnel, including our senior management, brokers and other key personnel, we have entered into various agreements with key employees setting up the conditions for the cash payment of certain retention bonuses. These bonuses are an incentive for these employees to remain with the company, for a fixed period of time, to allow us to capitalize on their knowledge and experience. We have various forms of retention bonus arrangements; some are paid up front and some are paid at the end of the term, but all are contingent upon successfully completing a minimum period of employment. A retention bonus that is paid to an employee upfront that is contingent on a certain minimum period of employment, will be initially classified as a prepaid asset and amortized to compensation expense as the future services are rendered over the duration of the stay period. A retention bonus that is paid to an employee at the end of the term that is contingent on a certain minimum period of employment, will be accrued as a liability through compensation expense as the future services are rendered over the duration of the stay period. If an employee leaves prior to the required time frame to earn the retention bonus outright, then all or any portion that is ultimately unearned or refundable, and recovered by the company if prepaid, is forfeited and reversed through compensation expense. Stock-Based Compensation We have several employee equity-settled and cash-settled share-based compensation plans. Equity-settled share-based payments to employees include grants of stock options, performance stock units and restricted stock units and are measured based on estimated grant date fair value. We have elected to use the Black-Scholes option pricing model to determine the fair value of stock options on the dates of grant. Performance stock units are measured on the probable outcome of the performance conditions applicable to each grant. Restricted stock units are measured based on the fair market values of the underlying stock on the dates of grant. Shares are issued on the vesting dates net of the minimum statutory tax withholding requirements, as applicable, to be paid by us on behalf of our employees. As a result, the actual number of shares issued will be fewer than the actual number of performance stock units and restricted stock units outstanding. Furthermore, we record the liability for withholding amounts to be paid by us as a reduction to additional paid-in Cash-settled share-based payments to employees include awards under our Performance Unit Program and stock appreciation rights. The fair value of the amount payable to employees in respect of cash-settled share-based payments is recognized as compensation expense, with a corresponding increase in liabilities, over the vesting period. The liability is remeasured at each reporting date and at settlement date. Any changes in fair value of the liability are recognized as compensation expense. We recognize share-based compensation expense over the requisite service period for awards expected to ultimately vest. Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs from original estimates. Employee Stock Purchase Plan We have an employee stock purchase plan (which we refer to as the ESPP), under which the sale of 8.0 million shares of our common stock has been authorized. Eligible employees may contribute up to 15% of their compensation towards the quarterly purchase of our common stock at a purchase price equal to 95% of the lesser of the fair market value of our common stock on the first business day or the last business day of the quarterly offering period. Eligible employees may annually purchase shares of our common stock with an aggregate fair market value of up to $25,000 (measured as of the first day of each quarterly offering period of each calendar year), provided that no employee may purchase more than 2,000 shares of our common stock under the ESPP during any calendar year. At December 31, 2017, 7.2 million shares of our common stock was reserved for future issuance under the ESPP. Defined Benefit Pension and Other Postretirement Plans We recognize in our consolidated balance sheet, an asset for our defined benefit postretirement plans’ overfunded status or a liability for our plans’ underfunded status. We recognize changes in the funded status of our defined benefit postretirement plans in comprehensive earnings in |

Effect of New Accounting Pronouncements | 2. Effect of New Accounting Pronouncements Hedge Accounting In August 2017, the FASB issued ASU No. 2017-12, last-of-layer Presentation of Net Periodic Pension and Postretirement Benefit Cost In March 2017, the FASB issued ASU No. 2017-07, Business Combinations In January 2017, the FASB issued ASU No. 2017-01, Intangibles - Goodwill and Other In January 2017, the FASB issued ASU No. 2017-04, non-cash Leases In February 2016, the FASB issued ASU No. 2016-02, right-of-use While we are continuing to assess all potential impacts of the new guidance, we anticipate this guidance will have an impact on our consolidated financial statements. We currently believe the most significant impact relates to our real estate operating leases and the related recognition of right-of-use Stock Compensation In May 2017, the FASB issued ASU No. 2017-09, 2017-09). 2017-09 In March 2016, the FASB issued ASU No. 2016-09, Compensation 2016-09). 2016-09 Cash Receipts and Cash Payments In August 2016, the FASB issued ASU No. 2016-15, (ASU 2016-15). ASU 2016-15 The adoption of this guidance resulted in a change to our classification whereby contingent payments on acquisitions that are up to the acquisition date fair value have been presented in financing activities and those payments in excess of the acquisition date fair value have been presented in operating activities. Historically these payments have all been included in investing activities. Accordingly, in our 2016 consolidated statement of cash flows, we reclassified $22.8 million and $45.5 million of payments from investing activities to operating activities and financing activities, respectively, to conform to the current year presentation. In our 2015 consolidated statement of cash flows, we reclassified $12.1 million and $21.8 million of payments from investing activities to operating activities and financing activities, respectively, to conform to the current year presentation. The modifications can be seen in our statement of cash flows. Income Taxes In October 2016, the FASB issued ASU No. 2016-16, Restricted Cash In November 2016, the FASB issued ASU No. 2016-18, 2016-18 2016-18 The following is a reconciliation of our December 31 cash, cash equivalents and restricted cash balances as presented in the consolidated statement of cash flows for the years ended December 31, 2017, 2016 and 2015 (in millions): December 31, 2017 2016 2015 Cash and cash equivalents $ 681.2 $ 545.5 $ 480.4 Restricted cash 1,623.8 1,392.1 1,412.1 Total cash, cash equivalents and restricted cash $ 2,305.0 $ 1,937.6 $ 1,892.5 Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, pre-2018 We adopted ASC Topic 606 as of January 1, 2018, using the full retrospective method to restate each prior reporting period presented. An assessment to determine the impacts of the new accounting standard has been performed. We implemented new accounting and operational processes which were a result of the new guidance and analyzed the impact of these changes. We anticipate the cumulative effect of the adoption to be recognized will be an increase to retained earnings of between $100.0 million and $180.0 million on January 1, 2016. At the time of this filing we are completing our final review of the amount. Our final review includes steps related to our international locations, our acquired companies and ensuring these multiple systems have complied with the processes that we have established. We anticipate this standard will have a material impact on individual lines in our consolidated financial statements, but we do not expect it will have as much of an impact on our results of operations on an annual basis. The primary impacts of the new standard to our product and service lines are anticipated to be as follows: Brokerage segment Revenue The primary reason for the increase in the amount of revenue recognized relates to our employee benefits business. Historically we have recognized this revenue throughout the contract period as underlying client exposure units became certain. Under the new guidance, the full year revenue under each of these contracts will be estimated at the effective date of the underlying policies resulting in acceleration of revenue recognized, with a reassessment at each reporting date. This also will cause a shift in the timing of revenue recognized in the interim periods as a majority of these annual contracts incept in the first quarter. Partially offsetting this interim impact will be the recognition of contingent revenues related to all of our brokerage business as these revenues will be estimated and accrued throughout the year as the underlying business is placed with the insurance carriers rather than our historical recognition where the majority of these were recognized in the first quarter, typically when we received cash or the related policy detail or other carrier specific information from the insurance carrier. Expense Risk management segment Revenue Expense - Corporate segment We expect that the timing related to recognition of revenue in our corporate segment will remain substantially unchanged. We do not expect a material impact on our annual after tax earnings, but we do expect a material change in the emergence of our after tax earnings in the interim quarterly periods as income tax credits are recognized based on our quarterly consolidated pretax earnings patterns. |

Business Combinations | 3. Business Combinations During 2017, we acquired substantially all of the net assets of the following firms in exchange for our common stock and/or cash. These acquisitions have been accounted for using the acquisition method for recording business combinations (in millions, except share data): Name and Effective Date of Acquisition Common Common Cash Paid Accrued Escrow Recorded Total Maximum (000s ) Construction Risk Solutions, LLC (CRS) January 1, 2017 — $ — $ 27.9 $ — $ 3.1 $ 4.4 $ 35.4 $ 10.0 Hill, Chesson & Woody (HCW) January 1, 2017 — — 34.8 — 0.7 15.9 51.4 24.4 Presidio Group, Inc.

We record escrow deposits that are returned to us as a result of adjustments to net assets acquired as reductions of goodwill when the escrows are settled. The maximum potential earnout payables disclosed in the foregoing table represent the maximum amount of additional consideration that could be paid pursuant to the terms of the purchase agreement for the applicable acquisition. The amounts recorded as earnout payables, which are primarily based upon the estimated future operating results of the acquired entities over a two- The fair value of these earnout obligations is based on the present value of the expected future payments to be made to the sellers of the acquired entities in accordance with the provisions outlined in the respective purchase agreements, which is a Level 3 fair value measurement. In determining fair value, we estimated the acquired entity’s future performance using financial projections developed by management for the acquired entity and market participant assumptions that were derived for revenue growth and/or profitability. Revenue growth rates generally ranged from 5.0% to 17.0% for our 2017 acquisitions. We estimated future payments using the earnout formula and performance targets specified in each purchase agreement and these financial projections. We then discounted these payments to present value using a risk-adjusted rate that takes into consideration market-based During 2017, 2016 and 2015, we recognized $20.2 million, $16.9 million and $16.2 million, respectively, of expense in our consolidated statement of earnings related to the accretion of the discount recorded for earnout obligations in connection with our acquisitions. In addition, during 2017, 2016 and 2015, we recognized $10.7 million, $15.2 million and $24.4 million of expense, respectively, related to net adjustments in the estimated fair value of the liability for earnout obligations in connection with revised projections of future performance for 108, 101 and 105 acquisitions, respectively. The aggregate amount of maximum earnout obligations related to acquisitions made in 2014 and subsequent years was $567.9 million as of December 31, 2017, of which $264.2 million was recorded in the consolidated balance sheet as of that date based on the estimated fair value of the expected future payments to be made. The aggregate amount of maximum earnout obligations related to acquisitions made in 2013 and subsequent years was $527.2 million as of December 31, 2016, of which $242.3 million was recorded in the consolidated balance sheet as of that date based on the estimated fair value of the expected future payments to be made.

The excess of the purchase price over the estimated fair value of the tangible net assets acquired at the acquisition date was allocated to goodwill, expiration lists, non-compete Provisional estimates of fair value are established at the time of the acquisition and are subsequently reviewed within the first year of operations subsequent to the acquisition date to determine the necessity for adjustments. The fair value of the tangible assets and liabilities for each applicable acquisition at the acquisition date approximated their carrying values. The fair value of expiration lists was established using the excess earnings method, which is an income approach based on estimated financial projections developed by management for each acquired entity using market participant assumptions. Revenue growth and attrition rates generally ranged from 2.0% to 3.3% and 5.0% to 10.0% for our 2017 acquisitions, respectively, for which valuations were performed in 2017. We estimate the fair value as the present value of the benefits anticipated from ownership of the subject customer list in excess of returns required on the investment in contributory assets necessary to realize those benefits. The rate used to discount the net benefits was based on a risk-adjusted rate that takes into consideration market-based rates of return and reflects the risk of the asset relative to the acquired business. These discount rates generally ranged from 12.0% to 14.0% for our 2017 acquisitions, for which a valuation was performed. The fair value of non-compete non-compete Expiration lists, non-compete non-compete Of the $241.4 million of expiration lists, $3.6 million of non-compete agreements and $0.1 million of trade names related to the 2017 acquisitions, $65.1 million, $2.5 million and $0.1 million, respectively, is not expected to be deductible for income tax purposes. Accordingly, we recorded a deferred tax liability of $18.6 million, and a corresponding amount of goodwill, in 2017 related to the nondeductible amortizable intangible assets. Our consolidated financial statements for the year ended December 31, 2017 include the operations of the acquired entities from their respective acquisition dates. The following is a summary of the unaudited pro forma historical results, as if these entities had been acquired at January 1, 2016 (in millions, except per share data): Year Ended December 31, 2017 2016 Total revenues $ 6,222.8 $ 5,765.9 Net earnings attributable to controlling interests 466.3 414.5 Basic earnings per share 2.58 2.33 Diluted earnings per share 2.56 2.31 The unaudited pro forma results above have been prepared for comparative purposes only and do not purport to be indicative of the results of operations which actually would have resulted had these acquisitions occurred at January 1, 2016, nor are they necessarily indicative of future operating results. Annualized revenues of entities acquired in 2017 totaled approximately $172.3 million. Total revenues and net earnings recorded in our consolidated statement of earnings for 2017 related to the 2017 acquisitions in the aggregate, were $112.6 million and $4.7 million, respectively. |

The “make-whole amount” is derived from a net present value computation of the remaining scheduled payments of principal and interest using a discount rate based on the U.S. Treasury yield plus 0.5% and is designed to compensate the purchasers of the notes for their investment risk in the event prevailing interest rates at the time of prepayment are less favorable than the interest rates under the notes. We do not currently intend to prepay any of the notes. The note purchase agreements described above contain customary provisions for transactions of this type, including representations and warranties regarding us and our subsidiaries and various financial covenants, including covenants that require us to maintain specified financial ratios. We were in compliance with these covenants as of December 31, 2017. The note purchase agreements also provide customary events of default, generally with corresponding grace periods, including, without limitation, payment defaults with respect to the notes, covenant defaults, cross-defaults to other agreements evidencing our or our subsidiaries’ indebtedness, certain judgments against us or our subsidiaries and events of bankruptcy involving us or our material subsidiaries. The notes issued under the note purchase agreement are senior unsecured obligations of ours and rank equal in right of payment with our Credit Agreement discussed below. Credit Agreement The Credit Agreement provides that we may elect that each borrowing in U.S. dollars be either base rate loans or eurocurrency loans, each as defined in the Credit Agreement. However, the Credit Agreement provides that all loans denominated in currencies other than U.S. dollars will be eurocurrency loans. Interest rates on base rate loans and outstanding drawings on letters of credit in U.S. dollars under the Credit Agreement will be based on the base rate, as defined in the Credit Agreement, plus a margin of 0.00% to 0.45%, depending on the financial leverage ratio we maintain. Interest rates on eurocurrency loans or outstanding drawings on letters of credit in currencies other than U.S. dollars under the Credit Agreement will be based on adjusted LIBOR, as defined in the Credit Agreement, plus a margin of 0.85% to 1.45%, depending on the financial leverage ratio we maintain. Interest rates on swing loans will be based, at our election, on either the base rate or an alternate rate that may be quoted by the lead lender. The annual facility fee related to the Credit Agreement is 0.15% and 0.30% of the revolving credit commitment, depending on the financial leverage ratio we maintain. In connection with entering into the Credit Agreement, we incurred approximately $2.0 million of debt acquisition costs that were capitalized and will be amortized on a pro rata basis over the term of the Credit Agreement. The terms of the Credit Agreement include various financial covenants, including covenants that require us to maintain specified financial ratios. We were in compliance with these covenants as of December 31, 2017. The Credit Agreement also includes customary provisions for transactions of this type, including events of default, with corresponding grace periods and cross-defaults At December 31, 2017, $17.2 million of letters of credit (for which we had $13.5 million of liabilities recorded at December 31, 2017) were outstanding under the Credit Agreement. See Note 15 to these consolidated financial statements for a discussion of the letters of credit. There were $190.0 million of borrowings outstanding under the Credit Agreement at December 31, 2017. Accordingly, at December 31, 2017, $592.8 million remained available for potential borrowings, of which $57.8 million was available for additional letters of credit. Premium Financing Debt Facility - The interest rates on Facility B are Interbank rates, which vary by tranche, duration and currency, plus a margin of 1.05%. The interest rates on Facilities C and D are 30 day Interbank rates, plus a margin of 0.55%. The annual fee for Facility B is 0.4725% of the undrawn commitments for the two tranches of the facility. The annual fee for Facilities C and D is 0.50% of the total commitments of the facilities. The terms of our Premium Financing Debt Facility include various financial covenants, including covenants that require us to maintain specified financial ratios. We were in compliance with these covenants as of December 31, 2017. The Premium Financing Debt Facility also includes customary provisions for transactions of this type, including events of default, with corresponding grace periods and cross-defaults to other agreements evidencing our indebtedness. Facilities B, C and D are secured by the premium finance receivables of the Australian and New Zealand premium finance subsidiaries. At December 31, 2017, AU$150.0 million and NZ$8.0 million of borrowings were outstanding under Facility B, AU$23.9 million of borrowings were outstanding under Facility C and NZ$14.9 million of borrowings were outstanding under Facility D. Accordingly, as of December 31, 2017, AU$10.0 million and NZ$17.0 million remained available for potential borrowing under Facility B, and AU$1.1 million and NZ$0.1 million under Facilities C and D, respectively. See Note 15 to these 2017 consolidated financial statements for additional discussion on our contractual obligations and commitments as of December 31, 2017. The aggregate estimated fair value of the $2,798.0 million in debt under the note purchase agreements at December 31, 2017 was $2,920.7 million due to the long-term duration and fixed interest rates associated with these debt obligations. No active or observable market exists for our private long-term debt. Therefore, the estimated fair value of this debt is based on discounted future cash flows, which is a Level 3 fair value measurement, using current interest rates available for debt with similar terms and remaining maturities. The estimated fair value of this debt is based on the income valuation approach, which is a valuation technique that converts future amounts (for example, cash flows or income and expenses) to a single current (that is, discounted) amount. The fair value measurement is determined on the basis of the value indicated by current market expectations about those future amounts. Because our debt issuances generate a measurable income stream for each lender, the income approach was deemed to be an appropriate methodology for valuing the private placement long-term debt. The methodology used calculated the original deal spread at the time of each debt issuance, which was equal to the difference between the yield of each issuance (the coupon rate) and the equivalent benchmark treasury yield at that time. The market spread as of the valuation date was calculated, which is equal to the difference between an index for investment grade insurers and the equivalent benchmark treasury yield today. An implied premium or discount to the par value of each debt issuance based on the difference between the origination deal spread and market as of the valuation date was then calculated. The index we relied on to represent investment graded insurers was the Bloomberg Valuation Services (BVAL) U.S. Insurers BBB index. This index is comprised primarily of insurance brokerage firms and was representative of the industry in which we operate. For the purposes of our analysis, the average BBB rate was assumed to be the appropriate borrowing rate for us based on our current estimated credit rating. The estimated fair value of the $190.0 million of borrowings outstanding under our Credit Agreement approximate their carrying value due to their short-term duration and variable interest rates. The estimated fair value of the $151.1 million of borrowings outstanding under our Premium Financing Debt Facility approximates their carrying value due to their short-term duration and variable interest rates. |

Earnings per Share | 8. Earnings per Share The following table sets forth the computation of basic and diluted net earnings per share (in millions, except per share data): Year Ended December 31, 2017 2016 2015 Net earnings attributable to controlling interests $ 463.1 $ 414.4 $ 356.8 Weighted average number of common shares outstanding 180.1 177.6 172.2 Dilutive effect of stock options using the treasury stock method 2.0 0.8 1.0 Weighted average number of common and common equivalent shares outstanding 182.1 178.4 173.2 Basic net earnings per share $ 2.57 $ 2.33 $ 2.07 Diluted net earnings per share $ 2.54 $ 2.32 $ 2.06 Options to purchase 1.3 million, 5.9 million and 3.5 million shares of our common stock were outstanding at December 31, 2017, 2016 and 2015, respectively, but were not included in the computation of the dilutive effect of stock options for the year then ended. These stock options were excluded from the computation because the options’ exercise prices were greater than the average market price of our common shares during the respective period and, therefore, would be anti-dilutive to earnings per share under the treasury stock method. |

Stock Option Plans | 9. Stock Option Plans On May 16, 2017, our stockholders approved the Arthur J. Gallagher 2017 Long-Term Incentive Plan (which we refer to as the LTIP), which replaced our previous stockholder-approved Arthur J. Gallagher & Co. 2014 Long-Term Incentive Plan (which we refer to as the 2014 LTIP). The LTIP term began May 16, 2017 and terminates on the date of the annual meeting of stockholders in 2027, unless terminated earlier by our board of directors. All of our officers, employees and non-employee non-qualified Shares of our common stock available for issuance under the LTIP include authorized and unissued shares of common stock or authorized and issued shares of common stock reacquired and held as treasury shares or otherwise, or a combination thereof. The number of available shares will be reduced by the aggregate number of shares that become subject to outstanding awards granted under the LTIP. To the extent that shares subject to an outstanding award granted under either the LTIP or prior equity plans are not issued or delivered by reason of the expiration, termination, cancellation or forfeiture of such award or by reason of the settlement of such award in cash, then such shares will again be available for grant under the LTIP. The maximum number of shares available under the LTIP for restricted stock, restricted stock unit awards and performance unit awards settled with stock (i.e., all awards other than stock options and stock appreciation rights) is 4.0 million as of December 31, 2017. The LTIP provides for the grant of stock options, which may be either tax-qualified non-qualified non-qualified tax-qualified non-qualified tax-qualified Upon exercise, the option exercise price may be paid in cash, by the delivery of previously owned shares of our common stock, through a net-exercise non-transferable. On March 16, 2017, the compensation committee granted 1,650,400 options under the 2014 LTIP to our officers and key employees that become exercisable at the rate of 34%, 33% and 33% on the anniversary date of the grant in 2020, 2021 and 2022, respectively. On March 17, 2016, the compensation committee granted 2,576,000 options to our officers and key employees that become exercisable at the rate of 34%, 33% and 33% on the anniversary date of the grant in 2019, 2020 and 2021, respectively. On March 11, 2015, the compensation committee granted 1,941,000 options to our officers and key employees that become exercisable at the rate of 34%, 33% and 33% on the anniversary date of the grant in 2018, 2019 and 2020, respectively. The 2017, 2016 and 2015 options expire seven years from the date of grant, or earlier in the event of termination of the employee. For certain of our executive officers age 55 or older, stock options awarded in 2017, 2016 and 2015 are no longer subject to forfeiture upon such officers’ departure from the company after two years from the date of grant. Our stock option plans provide for the immediate vesting of all outstanding stock option grants in the event of a change in control of our company, as defined in the applicable plan documents. During 2017, 2016 and 2015, we recognized $17.3 million, $14.7 million and $11.2 million, respectively, of compensation expense related to our stock option grants. For purposes of expense recognition in 2017, 2016 and 2015, the estimated fair values of the stock option grants are amortized to expense over the options’ vesting period. We estimated the fair value of stock options at the date of grant using the Black-Scholes option pricing model with the following weighted average assumptions: Year Ended December 31, 2017 2016 2015 Expected dividend yield 2.8 % 3.0 % 3.0 % Expected risk-free interest rate 2.3 % 1.6 % 1.8 % Volatility 27.2 % 27.7 % 28.2 % Expected life (in years) 5.0 5.5 5.5 Option valuation models require the input of highly subjective assumptions including the expected stock price volatility. The Black-Scholes option pricing model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. Because our employee and director stock options have characteristics significantly different from those of traded options, and because changes in the selective input assumptions can materially affect the fair value estimate, in management’s opinion, the existing models do not necessarily provide a reliable single measure of the fair value of our employee and non-employee The following is a summary of our stock option activity and related information for 2017, 2016 and 2015 (in millions, except exercise price and year data): Shares Weighted Weighted Aggregate Year Ended December 31, 2017 Beginning balance 10.3 $ 41.40 Granted 1.7 56.87 Exercised (1.3 ) 33.11 Forfeited or canceled (0.1 ) 34.33 Ending balance 10.6 $ 44.95 3.94 $ 193.4 Exercisable at end of year 2.5 $ 37.81 1.74 $ 64.0 Ending vested and expected to vest 10.4 $ 44.88 3.92 $ 191.1 Year Ended December 31, 2016 Beginning balance 8.8 $ 39.25 Granted 2.6 43.72 Exercised (1.1 ) 29.50 Forfeited or canceled — — Ending balance 10.3 $ 41.40 4.15 $ 108.8 Exercisable at end of year 2.2 $ 32.37 1.73 $ 43.7 Ending vested and expected to vest 10.1 $ 41.34 4.12 $ 107.5 Year Ended December 31, 2015 Beginning balance 8.4 $ 35.49 Granted 1.9 46.19 Exercised (1.4 ) 27.59 Forfeited or canceled (0.1 ) 27.59 Ending balance 8.8 $ 39.25 4.16 $ 36.7 Exercisable at end of year 2.1 $ 28.54 1.92 $ 25.9 Ending vested and expected to vest 8.7 $ 39.15 4.13 $ 36.6 Options with respect to 16.2 million shares (less any shares of restricted stock issued under the LTIP—see Note 11 to these consolidated financial statements) were available for grant under the LTIP at December 31, 2017. The total intrinsic value of options exercised during 2017, 2016 and 2015 amounted to $32.7 million, $19.3 million and $27.0 million, respectively. As of December 31, 2017, we had approximately $42.8 million of total unrecognized compensation cost related to nonvested options. We expect to recognize that cost over a weighted average period of approximately four years.

Deferred Compensation | 10. Deferred Compensation We have a Deferred Equity Participation Plan, (which we refer to as the DEPP), which is a non-qualified one-year one-year sub-plans sub-plans) Our common stock that is issued to or purchased by the rabbi trust as a contribution under DEPP is valued at historical cost, which equals its fair market value at the date of grant or date of purchase. When common stock is issued, we record an unearned deferred compensation obligation as a reduction of capital in excess of par value in the accompanying consolidated balance sheet, which is amortized to compensation expense ratably over the vesting period of the participants. Future changes in the fair market value of our common stock owed to the participants do not have any impact on the amounts recorded in our consolidated financial statements. In the first quarter of each of 2017, 2016 and 2015, the compensation committee approved $14.0 million, $10.1 million and $8.9 million, respectively, of awards in the aggregate to certain key executives under the DEPP that were contributed to the rabbi trust in the first quarters of 2017, 2016 and 2015. We contributed cash to the rabbi trust and instructed the trustee to acquire a specified number of shares of our common stock on the open market to fund these 2017, 2016 and 2015 awards. In the second quarter of 2013, we instructed the trustee for the DEPP to liquidate all investments held under the DEPP, other than our common stock, and use the proceeds to purchase additional shares of our common stock on the open market. As a result, the DEPP sold all of the funded cash award assets and purchased 1.2 million shares of our common stock at an aggregate cost of $52.4 million during the second quarter of 2013. During 2017, 2016 and 2015, we charged $9.6 million, $7.5 million and $7.2 million, respectively, to compensation expense related to these awards. In 2017 and 2016, the compensation committee approved $4.0 million and $13.6 million, respectively, of awards under the sub-plans sub-plans At December 31, 2017 and 2016, we recorded $54.7 million (related to 2.6 million shares) and $46.8 million (related to 2.4 million shares), respectively, of unearned deferred compensation as an reduction of capital in excess of par value in the accompanying consolidated balance sheet. The total intrinsic value of our unvested equity based awards under the plan at December 31, 2017 and 2016 was $166.0 million and $125.5 million, respectively. During 2017, 2016 and 2015, cash and equity awards with an aggregate fair value of $8.4 million, $7.6 million and $2.3 million, respectively, were vested and distributed to executives under the DEPP.

Restricted Stock, Performance Share and Cash Awards | 11. Restricted Stock, Performance Share and Cash Awards Restricted Stock Awards As discussed in Note 9 to these consolidated financial statements, on May 16, 2017, our stockholders approved the LTIP, which replaced our previous stockholder-approved 2014 LTIP. The LTIP provides for the grant of a stock award either as restricted stock or as restricted stock units. In either case, the compensation committee may determine that the award will be subject to the attainment of performance measures over an established performance period. Stock awards and the related dividend equivalents are non-transferable The agreements awarding restricted stock units under the LTIP will specify whether such awards may be settled in shares of our common stock, cash or a combination of shares and cash and whether the holder will be entitled to receive dividend equivalents, on a current or deferred basis, with respect to such award. Prior to the settlement of a restricted stock unit, the holder of a restricted stock unit will have no rights as a stockholder of the company. The maximum number of shares available under the LTIP for restricted stock, restricted stock units and performance unit awards settled with stock (i.e., all awards other than stock options and stock appreciation rights) is 4.0 million. At December 31, 2017, 4.0 million shares were available for grant under the LTIP for such awards. Prior to May 12, 2009, we had a restricted stock plan for our directors, officers and certain other employees, which was superseded by the 2009 LTIP. Under the provisions of that plan, we were authorized to issue 4.0 million restricted shares or related stock units of our common stock. The compensation committee was responsible for the administration of the plan. Each award granted under the plan represented a right of the holder of the award to receive shares of our common stock, cash or a combination of shares and cash, subject to the holder’s continued employment with us for a period of time after the date the award is granted. The compensation committee determined each recipient of an award under the plan, the number of shares of common stock subject to such award and the period of continued employment required for the vesting of such award. In 2017, 2016 and 2015, we granted 476,350, 479,167 and 394,975 restricted stock units, respectively, to employees under the LTIP and 2014 LTIP, with an aggregate fair value of $26.8 million, $20.4 million and $16.7 million, respectively, at the date of grant. The 2017, 2016 and 2015 restricted stock units vest as follows: 477,500 units granted in first quarter 2017, 466,600 units granted in first quarter 2016 and 362,600 units granted in first quarter 2015, vest in full based on continued employment through March 19, 2022, March 17, 2021 and March 11, 2020, respectively, while the other 2017, 2016 and 2015 restricted stock unit awards generally vest in full based on continued employment through the vesting period on the anniversary date of the grant. For certain of our executive officers age 55 or older, restricted stock units awarded in 2017, 2016 and 2015 are not subject to forfeiture upon such officers’ departure from the company after two years from the date of grant. The vesting periods of the 2017, 2016 and 2015 restricted stock unit awards are as follows (in actual shares): Restricted Stock Units Granted Vesting Period 2017 2016 2015 One year 21,600 27,417 22,175 Four years — — 9,200 Five years 454,750 451,750 363,600 Total shares granted 476,350 479,167 394,975 We account for restricted stock awards at historical cost, which equals its fair market value at the date of grant, which is amortized to compensation expense ratably over the vesting period of the participants. Future changes in the fair value of our common stock that is owed to the participants do not have any impact on the amounts recorded in our consolidated financial statements. During 2017, 2016 and 2015, we charged $19.6 million, $18.2 million and $14.4 million, respectively, to compensation expense related to restricted stock awards granted in 2007 through 2017. The total intrinsic value of unvested restricted stock at December 31, 2017 and 2016 was $109.3 million and $80.0 million, respectively. During 2017 and 2016, equity awards (including accrued dividends) with an aggregate fair value of $23.3 million and $14.2 million were vested and distributed to employees under this plan. Performance Share Awards On March 16, 2017, March 17, 2016 and March 11, 2015, pursuant to the LTIP and 2014 LTIP, the compensation committee approved 86,250, 72,900 and 53,900, respectively of provisional performance unit awards, with an aggregate fair value of $4.9 million, $3.2 million and $2.5 million, respectively, for future grants to our officers. Each performance unit award was equivalent to the value of one share of our common stock on the date such provisional award was approved. At the end of the performance period, eligible participants will be granted a number of units based on achievement of the performance goal and subject to approval by the compensation committee. Granted units for the 2017, 2016 and 2015 provisional awards will fully vest based on continuous employment through March 16, 2020, March 17, 2019 and March 11, 2018, respectively, and will be settled in shares of our common stock on a one-for-one one-year two-year one-for-one Cash Awards On March 16, 2017, pursuant to our Performance Unit Program (which we refer to as the Program), the compensation committee approved provisional cash awards of $14.3 million in the aggregate for future grants to our officers and key employees that are denominated in units (255,000 units in the aggregate), each of which was equivalent to the value of one share of our common stock on the date the provisional award was approved.

Based on our performance for 2016, we granted 385,000 units under the Program in first quarter 2017 that will fully vest on January 1, 2019. During 2017, we charged $10.6 million to compensation expense related to these awards. We did not recognize any compensation expense during 2016 related to the 2016 provisional award under the Program.

Retirement Benefits [Abstract] | |
Retirement Plans | 12. Retirement Plans We have a noncontributory defined benefit pension plan that, prior to July 1, 2005, covered substantially all of our domestic employees who had attained a specified age and one year of employment. Benefits under the plan were based on years of service and salary history. In 2005, we amended our defined benefit pension plan to freeze the accrual of future benefits for all U.S. employees, effective on July 1, 2005. Since the plan is frozen, there is no difference between the projected benefit obligation and accumulated benefit obligation at December 31, 2017 and 2016. In the table below, the service cost component represents plan administration costs that are incurred directly by the plan. A reconciliation of the beginning and ending balances of the pension benefit obligation and fair value of plan assets and the funded status of the plan is as follows (in millions): Year Ended December 31, 2017 2016 Change in pension benefit obligation: Benefit obligation at beginning of year $ 261.3 $ 261.8 Service cost 1.7 1.5 Interest cost 10.0 10.8 Net actuarial loss 11.5 1.8 Benefits paid (13.1 ) (14.6 ) Benefit obligation at end of year $ 271.4 $ 261.3 Change in plan assets: Fair value of plan assets at beginning of year $ 207.8 $ 207.5 Actual return on plan assets 24.7 14.9 Contributions by the company — — Benefits paid (13.1 ) (14.6 ) Fair value of plan assets at end of year $ 219.4 $ 207.8 Funded status of the plan (underfunded) $ (52.0 ) $ (53.5 ) Amounts recognized in the consolidated balance sheet consist of: Noncurrent liabilities - accrued benefit liability $ (52.0 ) $ (53.5 ) Accumulated other comprehensive loss - net actuarial loss 63.7 67.9 Net amount included in retained earnings $ 11.7 $ 14.4 The components of the net periodic pension benefit cost for the plan and other changes in plan assets and obligations recognized in earnings and other comprehensive earnings consist of the following (in millions): Year Ended December 31, 2017 2016 2015 Net periodic pension cost: Service cost $ 1.7 $ 1.5 $ 1.1 Interest cost on benefit obligation 10.0 10.8 10.8 Expected return on plan assets (14.0 ) (14.6 ) (15.3 ) Amortization of net loss 5.0 5.3 6.2 Net periodic benefit cost 2.7 3.0 2.8 Other changes in plan assets and obligations recognized in other comprehensive earnings: Net loss incurred 0.8 1.4 2.9 Amortization of net loss (5.0 ) (5.3 ) (6.2 ) Total recognized in other comprehensive loss (4.2 ) (3.9 ) (3.3 ) Total recognized in net periodic pension cost and other comprehensive loss $ (1.5 ) $ (0.9 ) $ (0.5 ) Estimated amortization for the following year: Amortization of net loss $ 5.0 $ 5.5 $ 5.9 The following weighted average assumptions were used at December 31 in determining the plan’s pension benefit obligation: December 31, 2017 2016 Discount rate 3.50 % 4.00 % Weighted average expected long-term rate of return on plan assets 7.00 % 7.25 % The following weighted average assumptions were used at January 1 in determining the plan’s net periodic pension benefit cost: Year Ended December 31, 2017 2016 2015 Discount rate 4.00 % 4.25 % 4.00 % Weighted average expected long-term rate of return on plan assets 7.00 % 7.25 % 7.25 % The following benefit payments are expected to be paid by the plan (in millions): 2018 $ 13.5 2019 14.3 2020 14.3 2021 15.1 2022 15.4 Years 2023 to 2027 81.0 The following is a summary of the plan’s weighted average asset allocations at December 31 by asset category: December 31, Asset Category 2017 2016 Equity securities 61.0 % 61.0 % Debt securities 32.0 % 33.0 % Real estate 7.0 % 6.0 % Total 100.0 % 100.0 % Plan assets are invested in various pooled separate accounts under annuity contracts managed by two life underwriting enterprises. The plan’s investment policy provides that investments will be allocated in a manner designed to provide a long-term investment return greater than the actuarial assumptions, maximize investment return commensurate with risk and to comply with the Employee Income Retirement Security Act of 1974, as amended (which we refer to as ERISA), by investing the funds in a manner consistent with ERISA’s fiduciary standards. The weighted average expected long-term rate of return on plan assets assumption was determined based on a review of the asset allocation strategy of the plan using expected ten-year The following is a summary of the plan’s assets carried at fair value as of December 31 by level within the fair value hierarchy (in millions): December 31, Fair Value Hierarchy 2017 2016 Level 1 $ — $ — Level 2 107.5 108.1 Level 3 111.9 99.7 Total fair value $ 219.4 $ 207.8 The plan’s Level 2 assets consist of ownership interests in various pooled separate accounts within a life insurance carrier’s group annuity contract. The fair value of the pooled separate accounts is determined based on the net asset value of the respective funds, which is obtained from the underwriting enterprise and determined each business day with issuances and redemptions of units of the funds made based on the net asset value per unit as determined on the valuation date. We have not adjusted the net asset values provided by the underwriting enterprise. There are no restrictions as to the plan’s ability to redeem its investment at the net asset value of the respective funds as of the reporting date. The plan’s Level 3 assets consist of pooled separate accounts within another life insurance carrier’s annuity contracts for which fair value has been determined by an independent valuation. Due to the nature of these annuity contracts, our management makes assumptions to determine how a market participant would price these Level 3 assets. In determining fair value, the future cash flows to be generated by the annuity contracts were estimated using the underlying benefit provisions specified in each contract, market participant assumptions and various actuarial and financial models. These cash flows were then discounted to present value using a risk-adjusted rate that takes into consideration market based rates of return and probability-weighted present values. The following is a reconciliation of the beginning and ending balances for the Level 3 assets of the plan measured at fair value (in millions): Year Ended December 31, 2017 2016 Fair value at January 1 $ 99.7 $ 100.7 Settlements — (7.5 ) Unrealized gains 12.2 6.5 Fair value at December 31 $ 111.9 $ 99.7 We were not required under the IRC to make any minimum contributions to the plan for each of the 2017, 2016 and 2015 plan years. This level of required funding is based on the plan being frozen and the aggregate amount of our historical funding. During 2017, 2016 and 2015 we did not make discretionary contributions to the plan. We also have a qualified contributory savings and thrift (401(k)) plan covering the majority of our domestic employees. For eligible employees who have met the plan’s age and service requirements to receive matching contributions, we match 100% of pre-tax We also have a nonqualified deferred compensation plan, the Supplemental Savings and Thrift Plan, for certain employees who, due to IRS rules, cannot take full advantage of our matching contributions under the 401(k) plan. The plan permits these employees to annually elect to defer a portion of their compensation until their retirement or a future date. Our matching contributions to this plan (up to a maximum of the lesser of a participant’s elective deferral of base salary, annual bonus and commissions or 5.0% of eligible compensation, less matching amounts contributed under the 401(k) plan) are also at the discretion of our board of directors. We expensed $6.4 million, $5.8 million and $4.7 million related to contributions made to a rabbi trust maintained under the plan in 2017, 2016 and 2015, respectively. The fair value of the assets in the plan’s rabbi trust at December 31, 2017 and 2016, including employee contributions and investment earnings, was $329.0 million and $263.3 million, respectively, and has been included in other noncurrent assets and the corresponding liability has been included in other noncurrent liabilities in the accompanying consolidated balance sheet. We also have several foreign benefit plans, the largest of which is a defined contribution plan that provides for us to make contributions of 5.0% of eligible compensation. In addition, the plan allows for voluntary contributions by U.K. employees, which we match 100%, up to a maximum of an additional 5.0% of eligible compensation. Net expense for foreign retirement plans amounted to $32.0 million, $30.6 million and $31.7 million in 2017, 2016 and 2015, respectively. In 1992, we amended our health benefits plan to eliminate retiree coverage, except for retirees and those employees who had already attained a specified age and length of service at the time of the amendment. The retiree health plan is contributory, with contributions adjusted annually, and is funded on a pay-as-you-go |

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivatives and Hedging Activity | 14. Derivatives and Hedging Activity We are exposed to market risks, including changes in foreign currency exchange rates and interest rates. To manage the risk related to these exposures, we enter into various derivative instruments that reduce these risks by creating offsetting exposures. We generally do not enter into derivative transactions for trading or speculative purposes. Foreign Exchange Risk Management We are exposed to foreign exchange risk when it earns revenues, pays expenses, or enters into monetary intercompany transfers denominated in a currency that differs from its functional currency, or other transactions that are denominated in a currency other than its functional currency. We use foreign exchange derivatives, typically forward contracts and options, to reduce our overall exposure to the effects of currency fluctuations on cash flows. These exposures are hedged, on average, for less than two years. Interest Rate Risk Management We enter into various long term debt agreements. We use interest rate derivatives, typically swaps, to reduce our exposure to the effects of interest rate fluctuations on the forecasted interest rates for up to two years into the future. We have not received or pledged any collateral related to derivative arrangements at December 31, 2017. The notional and fair values of derivative instruments are as follows at December 31, 2017 and 2016 (in millions): Notional Amount Derivatives Assets (1) Derivative Liabilities (2) 2017 2016 2017 2016 2017 2016 Derivatives accounted for as hedges: Interest rate contracts $ 200.0 $ 200.0 $ 2.2 $ 11.4 $ — $ — Foreign exchange contracts (3) 18.7 4.1 8.1 2.1 2.9 17.5 Total $ 218.7 $ 204.1 $ 10.3 $ 13.5 $ 2.9 $ 17.5 (1) Included within other current assets $7.7 million and $12.5 million at December 31, 2017 and 2016, respectively and other non-current (2) Included within other current liabilities $1.6 million and $11.8 million at December 31, 2017 and 2016, respectively and other non-current (3) Included within foreign exchange contracts at December 31, 2017 were $141.0 million of call options offset with $141.0 million of put options and $13.3 million of buy forwards offset with $31.0 million of sell forwards.

Note Purchase Agreements, Credit Agreement and Premium Financing Debt Facility - Operating Lease Obligations - tax-increment We generally operate in leased premises at our other locations. Certain of these leases have options permitting renewals for additional periods. In addition to minimum fixed rentals, a number of leases contain annual escalation clauses which are generally related to increases in an inflation index. Total rent expense, including rent relating to cancelable leases and leases with initial terms of less than one year, amounted to $137.7 million in 2017, $134.2 million in 2016 and $121.6 million in 2015.

See Note 13 to these consolidated financial statements for a discussion of our funding commitments related to our corporate segment and the Off-Balance Since January 1, 2002, we have acquired 459 companies, all of which were accounted for using the acquisition method for recording business combinations. Substantially all of the purchase agreements related to these acquisitions contain provisions for potential earnout obligations. For all of our acquisitions made in the period from 2013 to 2017 that contain potential earnout obligations, such obligations are measured at fair value as of the acquisition date and are included on that basis in the recorded purchase price consideration for the respective acquisition. The amounts recorded as earnout payables are primarily based upon estimated future potential operating results of the acquired entities over a two- Off-Balance - At December 31, 2017, we had posted two letters of credit totaling $9.7 million in the aggregate, related to our self-insurance deductibles, for which we had a recorded liability of $12.8 million.

Since commitments may expire unused, the amounts presented in the table above do not necessarily reflect our actual future cash funding requirements. Litigation, Regulatory and Taxation Matters non-compete In July 2014, we were named in a lawsuit which asserts that we and other defendants are liable for infringement of a patent held by Nalco Company. The complaint sought a judgment of infringement, damages, costs and attorneys’ fees, and injunctive relief. Along with the other defendants, we disputed the allegation of infringement and have defended this matter vigorously. We filed a motion to dismiss the complaint on behalf of all defendants, alleging no infringement of Nalco’s intellectual property. This motion and similar motions attacking amended complaints filed by Nalco, were granted. On April 20, 2016, the court dismissed Nalco’s complaint and disallowed any further opportunity to amend or refile. Nalco appealed this ruling to the Federal Circuit Court and we are expecting a ruling during the first quarter of 2018. We continue to believe that the probability of a material loss is remote. However, litigation is inherently uncertain and it is not possible for us to predict the ultimate disposition of this proceeding. Our micro-captive advisory services are under investigation by the IRS. Additionally, the IRS has initiated audits for the 2012 tax year of over 100 of the micro-captive underwriting enterprises organized and/or managed by us. Among other matters, the IRS is investigating whether we have been acting as a tax shelter promoter in connection with these operations. While the IRS has not made specific allegations relating to our operations, if the IRS were to successfully assert that the micro-captives organized and/or managed by us do not meet the requirements of IRC Section 831(b), we could be held liable to pay monetary claims by the IRS and/or our micro-captive clients, and our future earnings from our micro-captive operations could be materially adversely affected, any of which events, could negatively impact the overall captive business and adversely affect our consolidated results of operations and financial condition. Due to the fact that the IRS has not made any allegation against us or completed all of its audits of our clients, we are not able to reasonably estimate the amount of any potential loss in connection with this investigation. Contingent Liabilities Tax-advantaged Due to the contingent nature of this exposure and our related assessment of its likelihood, no reserve has been recorded in our December 31, 2017 consolidated balance sheet related to this exposure. |

Insurance Operations | 16. Insurance Operations We have ownership interests in several underwriting enterprises based in the U.S., Bermuda, Gibraltar, Guernsey, Isle of Man and Malta that primarily operate segregated account “rent-a-captive” “rent-a-captive” “rent-a-captive” rent-a-captive rent-a-captive We have a wholly owned underwriting enterprise subsidiary based in the U.S. that cedes all of its insurance risk to reinsurers or captives under facultative and quota share treaty reinsurance agreements. This company was established in fourth quarter 2014 and began writing business in December 2014. These reinsurance arrangements diversify our business and minimize our exposure to losses or hazards of an unusual nature. The ceding of insurance does not discharge us of our primary liability to the policyholder. In the event that all or any of the reinsuring companies are unable to meet their obligations, we would be liable for such defaulted amounts. Therefore, we are subject to credit risk with respect to the obligations of our reinsurers or captives. In order to minimize our exposure to losses from reinsurer credit risk and insolvencies, we have managed that exposure by obtaining full collateral for which we typically require pledged assets, including cash and/or investment accounts or letters of credit, to fully offset the risk. Reconciliations of direct to net premiums, on a written and earned basis, for 2017, 2016 and 2015 related to the wholly-owned underwriting enterprise subsidiary discussed above are as follows (in millions): 2017 2016 2015 Written Earned Written Earned Written Earned Direct $ 60.7 $ 60.4 $ 71.8 $ 69.6 $ 71.5 $ 71.7 Assumed 5.0 4.5 5.2 4.9 4.4 5.1 Ceded (65.7 ) (64.9 ) (77.0 ) (74.5 ) (75.9 ) (76.8 ) Net $ — $ — $ — $ — $ — $ — At December 31, 2017 and 2016, our underwriting enterprise subsidiary had reinsurance recoverables of $59.8 million and $48.3 million, respectively, related to liabilities established for ceded unearned premium reserves and loss and loss adjustment expense reserves. These reinsurance recoverables relate to direct and assumed business that has been fully ceded to our reinsurers or captives and have been included in premiums and fees receivables in the accompanying consolidated balance sheet. |

Income Taxes | 17. Income Taxes We and our principal domestic subsidiaries are included in a consolidated U.S. Federal income tax return. Our international subsidiaries file various income tax returns in their jurisdictions. The foreign earnings (losses) before income taxes were $99.5 million in 2017, $5.6 million in 2016 and $(52.1) million in 2015. Earnings before income taxes include the impact of intercompany interest expense between domestic and foreign legal entities. Foreign intercompany interest expense was $64.2 million in 2017, $110.7 million in 2016 and $107.0 million in 2015. Domestic intercompany interest income was $64.2 million in 2017, $110.7 million in 2016 and $107.0 million in 2015. Significant components of earnings before income taxes and the provision for income taxes are as follows (in millions): Year Ended December 31, 2017 2016 2015 Earnings (losses) before income taxes: United States $ 278.6 $ 351.3 $ 345.6 Foreign, principally Australia, Canada, New Zealand and the U.K. 99.5 5.6 (52.1 ) Total earnings before income taxes $ 378.1 $ 356.9 $ 293.5 Provision (benefit) for income taxes: Federal: Current $ 16.4 $ 45.9 $ 43.9 Deferred (160.4 ) (146.7 ) (139.4 ) (144.0 ) (100.8 ) (95.5 ) State and local: Current 6.7 8.4 18.9 Deferred 1.4 (0.3 ) (3.3 ) 8.1 8.1 15.6 Foreign: Current 29.1 22.4 22.9 Deferred (14.3 ) (17.8 ) (38.6 ) 14.8 4.6 (15.7 ) Total benefit for income taxes $ (121.1 ) $ (88.1 ) $ (95.6 ) A reconciliation of the provision for income taxes with the U.S. Federal statutory income tax rate is as follows (in millions, except percentages): Year Ended December 31, 2017 2016 2015 Amount % of Amount % of Amount % of Federal statutory rate $ 132.4 35.0 $ 124.9 35.0 $ 102.7 35.0 State income taxes - net of Federal benefit 5.3 1.4 5.3 1.5 10.2 3.5 Differences related to non U.S. operations (48.5 ) (12.8 ) (34.1 ) (9.6 ) (22.6 ) (7.7 ) Alternative energy, foreign and other tax credits (230.1 ) (60.9 ) (194.4 ) (54.5 ) (181.3 ) (61.8 ) Other permanent differences (10.6 ) (2.8 ) (4.8 ) (1.3 ) (4.9 ) (1.7 ) U.S. repatriation tax 36.8 9.7 — — — — Stock-based compensation (15.1 ) (4.0 ) — — — — Changes in unrecognized tax benefits (0.9 ) (0.2 ) 2.2 0.6 3.0 1.0 Change in valuation allowance 12.3 3.3 14.0 3.9 1.7 0.6 Change in U.S. and U.K. tax rates (2.2 ) (0.6 ) (1.5 ) (0.4 ) (4.2 ) (1.4 ) Other (0.5 ) (0.1 ) 0.3 0.1 (0.2 ) (0.1 ) Benefit for income taxes $ (121.1 ) (32.0 ) $ (88.1 ) (24.7 ) $ (95.6 ) (32.6 ) A reconciliation of the beginning and ending balances of the total amounts of gross unrecognized tax benefits is as follows (in millions): December 31, 2017 2016 Gross unrecognized tax benefits at January 1 $ 14.5 $ 15.7 Increases in tax positions for current year 1.6 2.4 Settlements (1.8 ) (1.4 ) Lapse in statute of limitations (0.7 ) (1.8 ) Increases in tax positions for prior years 0.6 1.8 Decreases in tax positions for prior years (3.3 ) (2.2 ) Gross unrecognized tax benefits at December 31 $ 10.9 $ 14.5 The total amount of net unrecognized tax benefits that, if recognized, would affect the effective tax rate was $9.0 million and $10.0 million at December 31, 2017 and 2016, respectively. We accrue interest and penalties related to unrecognized tax benefits in our provision for income taxes. At December 31, 2017 and 2016, we had accrued interest and penalties related to unrecognized tax benefits of $2.9 million and $2.8 million, respectively. We file income tax returns in the U.S. and in various state, local and foreign jurisdictions. We are routinely examined by tax authorities in these jurisdictions. At December 31, 2017, our corporate returns had been examined by the IRS through calendar year 2010. The IRS is currently conducting various examinations of calendar years 2011 and 2012. In addition, a number of foreign, state, local and partnership examinations are currently ongoing. It is reasonably possible that our gross unrecognized tax benefits may change within the next twelve months. However, we believe any changes in the recorded balance would not have a significant impact on our consolidated financial statements. Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Significant components of our deferred tax assets and liabilities are as follows (in millions): December 31, 2017 2016 Deferred tax assets: Alternative minimum tax and other credit carryforwards $ 683.3 $ 477.9 Accrued and unfunded compensation and employee benefits 143.2 219.0 Amortizable intangible assets 45.8 38.8 Compensation expense related to stock options 13.4 16.9 Accrued liabilities 28.9 31.7 Accrued pension liability 14.8 22.9 Investments 1.1 7.7 Net operating loss carryforwards 30.5 20.4 Capital loss carryforwards 12.9 16.0 Deferred rent liability 4.8 8.1 Other 5.5 3.9 Total deferred tax assets 984.2 863.3 Valuation allowance for deferred tax assets (79.1 ) (66.8 ) Deferred tax assets 905.1 796.5 Deferred tax liabilities: Nondeductible amortizable intangible assets 273.8 310.2 Investment-related partnerships 17.6 34.5 Depreciable fixed assets 26.5 18.2 Hedging instruments 3.8 4.1 Other prepaid items 10.3 4.1 Total deferred tax liabilities 332.0 371.1 Net deferred tax assets $ 573.1 $ 425.4 At December 31, 2017 and 2016, $332.0 million and $371.1 million, respectively, have been included in noncurrent liabilities in the accompanying consolidated balance sheet. Alternative minimum tax credits of $108.2 million have an indefinite life and will be utilized or refunded beginning in 2018 and ending in 2021, according to a specific formula, general business tax credits of $571.6 million begin to expire, if not utilized, in 2034, and state credits of $3.5 million expire, if not used, in 2021. We expect the historically favorable trend in earnings before income taxes to continue in the foreseeable future. Accordingly, we expect to make full use of the net deferred tax assets. Valuation allowances have been established for certain foreign intangible assets and various state net operating loss carryforwards that may not be utilized in the future. We do not provide for U.S. Federal income taxes on the undistributed earnings ($330.0 million and $243.0 million at December 31, 2017 and 2016, respectively) of foreign subsidiaries which are considered permanently invested outside of the U.S. The amount of unrecognized deferred tax liability on these undistributed earnings was immaterial at December 31, 2017 and $15.6 million at December 31, 2016, respectively. If undistributed earnings are repatriated to the U.S. in the future they would be considered previously taxed income in the U.S., however the amount of unrecognized tax liability on these earnings is not expected to be material. On December 22, 2017, the U.S. enacted tax legislation commonly referred to as the Tax Cuts and Jobs Act (which we refer to as the Tax Act), which significantly revises the U.S. tax code by, among other things, lowering the corporate income tax rate from 35.0% to 21.0%; limiting the deductibility of interest expense; implementing a territorial tax system, and imposing a repatriation tax on deemed repatriated earnings of foreign subsidiaries. See discussion of repatriation tax below. SEC Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (which we refer to as SAB 118) describes three scenarios associated with a company’s status of accounting for income tax reform. Under the SAB 118 guidance, we have determined that we are able to make reasonable estimates for certain effects of tax reform. In our 2017 consolidated financial statements, we have recognized provisional amounts for our deferred income taxes and repatriation tax based on reasonable estimates. However, as of the date of this Annual Report on Form 10-K, Deferred Income Taxes: Repatriation Tax: one-time Cost Recovery |

During 2017, 2016 and 2015, $5.2 million of expense, $8.2 million of expense and $0.7 million of income, respectively, related to the fair value of derivative investments, was reclassified from accumulated other comprehensive earnings (loss) to the statement of earnings.

Segment Reporting [Abstract] | |
Segment Information | 20. Segment Information We have three reportable operating segments: brokerage, risk management and corporate. Our brokerage segment is primarily comprised of our retail and wholesale insurance brokerage operations. Our brokerage segment generates revenues through commissions paid by underwriting enterprises and through fees charged to our clients. Our brokers, agents and administrators act as intermediaries between underwriting enterprises and our clients and we do not assume net underwriting risks. Our risk management segment provides contract claim settlement and administration services for enterprises that choose to self-insure some or all of their property/casualty coverages and for underwriting enterprises that choose to outsource some or all of their property/casualty claims departments. These operations also provide claims management, loss control consulting and insurance property appraisal services. Revenues are principally generated on a negotiated per-claim per-service Our corporate segment manages our clean energy investments. In addition, our corporate segment reports the financial information related to our debt, and external acquisition-related expenses and other corporate costs. Allocations of investment income and certain expenses are based on reasonable assumptions and estimates primarily using revenue, headcount and other information. We allocate the provision for income taxes to the brokerage and risk management segments using the local county statutory rates. Reported operating results by segment would change if different methods were applied.

Accounting Policies [Abstract] | |
Nature of Operations | Nature of Operations Arthur J. Gallagher & Co. and its subsidiaries, collectively referred to herein as we, our, us or the company, provide insurance brokerage, consulting and third party claims settlement and administration services to both domestic and international entities through three reportable operating segments. Our brokers, agents and administrators act as intermediaries between underwriting enterprises and our clients. Our brokerage segment operations provide brokerage and consulting services to companies and entities of all types, including commercial, not-for-profit, not-for-profit, Chem-Mod We do not assume underwriting risk on a net basis, other than with respect to de minimis amounts necessary to provide minimum or regulatory capital amounts to organize captives, pools, specialized underwriters or risk-retention groups. Rather, capital necessary for events of loss coverages is provided by underwriting enterprises. Investment income and other revenues are generated from our premium financing operations and our investment portfolio, which includes our invested cash and restricted cash we hold on behalf of our clients, as well as clean energy investments. We are headquartered in Rolling Meadows, Illinois, have operations in 32 countries and offer client-service capabilities in more than 150 countries globally through a network of correspondent insurance brokers and consultants. |
Basis of Presentation | Basis of Presentation The accompanying consolidated financial statements include our accounts and all of our majority-owned subsidiaries (50% or greater ownership). Substantially all of our investments in partially owned entities in which our ownership is less than 50% are accounted for using the equity method based on the legal form of our ownership interest and the applicable ownership percentage of the entity. However, in situations where a less than 50%-owned investment has been determined to be a VIE and we are deemed to be the primary beneficiary in accordance with the variable interest model of consolidation, we will consolidate the investment into our consolidated financial statements. For partially owned entities accounted for using the equity method, our share of the net earnings of these entities is included in consolidated net earnings. All material intercompany accounts and transactions have been eliminated in consolidation. In the preparation of our consolidated financial statements as of December 31, 2017, management evaluated all material subsequent events or transactions that occurred after the balance sheet date through the date on which the financial statements were issued for potential recognition in our consolidated financial statements and/or disclosure in the notes thereto. |
Use of Estimates | Use of Estimates The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. These accounting principles require us to make estimates and assumptions that affect the reported amounts of assets and liabilities and revenues and expenses, and the disclosure of contingent assets and liabilities at the date of our consolidated financial statements. We are also required to make certain judgments and estimates that affect the disclosed amounts of revenues and expenses related to the potential impact of the adoption of and future accounting under ASC Topic 606. We periodically evaluate our estimates and assumptions, including those relating to the valuation of goodwill and other intangible assets, investments (including our IRC Section 45 investments), income taxes, stock-based compensation, claims handling obligations, retirement plans, litigation and contingencies. We base our estimates on historical experience and various assumptions that we believe to be reasonable based on specific circumstances. Such estimates and assumptions could change in the future as more information becomes known, which could impact the amounts reported and disclosed herein. |
Revenue Recognition | Revenue Recognition Our revenues are derived from commissions and fees as primarily specified in a written contract, or unwritten business understanding, with our clients or underwriting enterprises. We also recognize investment income over time from our invested assets and invested assets we hold on behalf of our clients or underwriting enterprises. |
Brokerage segment | Brokerage segment Our brokerage segment generates revenues by: (i) Identifying, negotiating and placing all forms of insurance or reinsurance coverages, as well as providing risk-shifting, risk-sharing and risk-mitigation consulting services, principally related to property/casualty, life, health, welfare and disability insurance. We also provide these services through, or in conjunction with, other unrelated agents and brokers, consultants and management advisors. (ii) Acting as an agent or broker for multiple underwriting enterprises by providing services such as sales, marketing, selecting, negotiating, underwriting, servicing and placing insurance coverage on their behalf. (iii) Providing consulting services related to health and welfare benefits, voluntary benefits, executive benefits, compensation, retirement planning, institutional investment and fiduciary, actuarial, compliance, private insurance exchange, human resource technology, communications, and benefits administration. (iv) Providing management and administrative services to captives, pools, risk-retention groups, healthcare exchanges, small underwriting enterprises, such as accounting, claims and loss processing assistance, feasibility studies, actuarial studies, data analytics and other administrative services. The vast majority of our brokerage contracts and service understandings are for a period of one year or less. Commissions and fees The primary source of brokerage segment revenues are commissions from underwriting enterprises, which are based on a percentage of premiums paid by our clients, or fees received from clients, which are based on an agreed level of service with our clients, usually in lieu of commissions. Commissions are fixed at the contract effective date and generally are based on a percentage of premiums for insurance coverage or employee head count for employer sponsored benefit plans. Commissions depend upon a large number of factors, including the type of risk being placed, the particular underwriting enterprise’s demand, the expected loss experience of the particular risk of coverage, and historical benchmarks surrounding the level of effort necessary for us to place and service the insurance contract. Fees are rarely tied to the amount of premiums; instead, they are based on an expected level of effort to provide our services. We recognize commission and fee revenues at the later of the billing or the effective date of the related insurance policies, net of an allowance for estimated policy cancellations. We recognize commission revenues related to installment premiums as the installments are billed. We recognize commissions on premiums directly billed by underwriting enterprises as revenue when we have obtained the data necessary to reasonably determine such amounts. Historically, we have not been able to reasonably determine these types of commission revenues until we have received the cash or the related policy detail or other specific information from the underwriting enterprise. Commissions on premiums billed directly by underwriting enterprises to the insureds generally relate to: (i) a large number of property/casualty insurance policy transactions, each with small premiums, and (ii) the number of enrolled employees in employer sponsored plans in our employee benefit brokerage operations. Under these direct bill arrangements, the underwriting enterprise controls the entire billing and policy issuance process. We record the income effects of subsequent premium adjustments when the adjustments become known. Fee revenues generated from the brokerage segment primarily relate to fees negotiated in lieu of commissions that we recognize in the same manner as commission revenues. We recognize these fee revenues ratably as the services are rendered, and record the income effects of subsequent fee adjustments when the adjustments become known. For consulting and advisory services, we recognize our revenue in the period in which we provide the service or advice. For management and administrative services, our revenue is recognized ratably over the contract period consistent with the performance of our obligations, mostly over an annual term. Supplemental revenues Certain underwriting enterprises may pay us additional revenues based on the volume of premium we place with them and for insights into our sales pipeline, our sales capabilities or our risk selection knowledge. These amounts are in excess of the commission and fee revenues discussed above, and not all business we place with underwriting enterprises is eligible for supplemental revenues. Unlike contingent revenues, discussed below, these revenues are a fixed amount or fixed percent of premium of the underlying eligible insurance contracts. We recognize supplemental revenues using internal data and information received from underwriting enterprises that allows us to reasonably estimate the supplemental revenues earned in the period. Contingent revenues Certain underwriting enterprises may pay us additional revenues for our sales capabilities, our risk selection knowledge, or our administrative efficiencies. These amounts are in excess of the commission revenues discussed above, and not all business we place with participating underwriting enterprises is eligible for contingent revenues. Unlike supplemental revenues, discussed above, these revenues are variable, generally based on growth, the loss experience of the underlying insurance contracts, and/or our efficiency in processing the business. We generally operate under calendar year contracts, but we do not receive these contingent revenues from the underwriting enterprises until the following calendar year, generally in the first and second quarters, after verification of the performance indicators outlined in the contracts. We recognize contingent revenues as revenue when we have obtained the data necessary to reasonably determine such amounts. Historically we have not been able to reasonably determine these types of revenues until we have received the cash or the related policy detail or other underwriting enterprise specific information from the underwriting enterprise. Sub-brokerage Sub-brokerage revenues. Sub-brokerage sub-brokers |
Investment income | Investment income Investment income primarily includes interest and dividend income (including interest income from our premium financing operations), which is accrued as it is earned. Gains on books of business sales represent one-time |
Claims Handling Obligations | Claims Handling Obligations We are obligated under certain circumstances to provide future claims handling and certain administrative services for our former global risks brokerage clients in the U.K. Our obligation is the result of following the industry practice of insurance brokers providing future claims handling and administrative services to former clients. In addition, under certain circumstances, our risk management segment operations are contractually obligated to provide contract claim settlement and administration services to our former clients. Accordingly, we record a liability for these deferred run-off |
Earnings per Share | Earnings per Share Basic net earnings per share is computed by dividing net earnings by the weighted average number of common shares outstanding during the reporting period. Diluted net earnings per share is computed by dividing net earnings by the weighted average number of common and common equivalent shares outstanding during the reporting period. Common equivalent shares include incremental shares from dilutive stock options, which are calculated from the date of grant under the treasury stock method using the average market price for the period. |
Cash and Cash Equivalents | Cash and Cash Equivalents Short-term investments, consisting principally of cash and money market accounts that have average maturities of 90 days or less, are considered cash equivalents. |
Restricted Cash | Restricted Cash In our capacity as an insurance broker, we collect premiums from insureds and, after deducting our commissions and/or fees, remit these premiums to underwriting enterprises. We hold unremitted insurance premiums in a fiduciary capacity until we disburse them, and the use of such funds is restricted by laws in certain states and foreign jurisdictions in which our subsidiaries operate. Various state and foreign agencies regulate insurance brokers and provide specific requirements that limit the type of investments that may be made with such funds. Accordingly, we invest these funds in cash and U.S. Treasury fund accounts. We can earn interest income on these unremitted funds, which is included in investment income in the accompanying consolidated statement of earnings. These unremitted amounts are reported as restricted cash in the accompanying consolidated balance sheet, with the related liability reported as premiums payable to underwriting enterprises. Additionally, several of our foreign subsidiaries are required by various foreign agencies to meet certain liquidity and solvency requirements. We were in compliance with these requirements at December 31, 2017. Related to our third party administration business and in certain of our brokerage operations, we are responsible for client claim funds that we hold in a fiduciary capacity. We do not earn any interest income on the funds held. These client funds have been included in restricted cash, along with a corresponding liability in premiums payable to underwriting enterprises in the accompanying consolidated balance sheet. |
Premiums and fees receivable | Premiums and fees receivable Premiums and fees receivable in the accompanying consolidated balance sheet are net of allowances for estimated policy cancellations and doubtful accounts. The allowance for estimated policy cancellations was $7.4 million and $7.1 million at December 31, 2017 and 2016, respectively, which represents a reserve for future reversals in commission and fee revenues related to the potential cancellation of client insurance policies that were in force as of each year end. The allowance for doubtful accounts was $13.5 million and $12.8 million at December 31, 2017 and 2016, respectively. We establish the allowance for estimated policy cancellations through a charge to revenues and the allowance for doubtful accounts through a charge to operating expenses. Both of these allowances are based on estimates and assumptions using historical data to project future experience. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein. We periodically review the adequacy of these allowances and make adjustments as necessary. |
Derivative Instruments | Derivative Instruments We are exposed to market risks, including changes in foreign currency exchange rates and interest rates. To manage the risk related to these exposures, we enter into various derivative instruments that reduce these risks by creating offsetting exposures In the normal course of business, we are exposed to the impact of foreign currency fluctuations that impact our results of operations and cash flows. We utilize a foreign currency risk management program involving foreign currency derivatives that consist of several monthly put/call options designed to hedge a portion of our future foreign currency disbursements through various future payment dates. To mitigate the counterparty credit risk we only enter into contracts with major financial institutions based upon their credit ratings and other factors. These derivative instrument contracts are cash flow hedges that qualify for hedge accounting and primarily hedge against fluctuations between changes in the GBP and Indian Rupee versus the U.S. dollar. Changes in fair value of the derivative instruments are reflected in other comprehensive earnings in the accompanying consolidated balance sheet. The impact of the hedge at maturity is recognized in the income statement as a component of investment income, compensation and operating expenses depending on the nature of the hedged item. We enter into various long term debt agreements. We use interest rate derivatives, typically swaps, to reduce our exposure to the effects of interest rate fluctuations on the forecasted interest rates for up to two years into the future. These derivative instrument contracts are periodically monitored for hedge ineffectiveness, the amount of which has not been material to the accompanying consolidated financial statements. We do not use derivatives for trading or speculative purposes. |
Premium Financing | Premium Financing Seven subsidiaries of the brokerage segment make short-term loans (generally with terms of twelve months or less) to our clients to finance premiums. These premium financing contracts are structured to minimize potential bad debt expense to us. Such receivables are generally considered delinquent after seven days of the payment due date. In normal course, insurance policies are cancelled within one month of the contractual payment due date if the payment remains delinquent. We recognize interest income as it is earned over the life of the contract using the “level-yield” method. Unearned interest related to contracts receivable is included in the receivable balance in the accompanying consolidated balance sheet. The outstanding loan receivable balance was $305.5 million and $241.2 million at December 31, 2017 and 2016, respectively. |
Fixed Assets | Fixed Assets We carry fixed assets at cost, less accumulated depreciation, in the accompanying consolidated balance sheet. We periodically review long-lived assets for impairment whenever events or changes in business circumstances indicate that the carrying value of the assets may not be recoverable. Under those circumstances, if the fair value were less than the carrying amount of the asset, we would recognize a loss for the difference. Depreciation for fixed assets is computed using the straight-line method over the following estimated useful lives: Useful Life Office equipment Three to ten years Furniture and fixtures Three to ten years Computer equipment Three to five years Building Fifteen to forty years Software Three to five years Refined fuel plants Ten years Leasehold improvements Shorter of the lease term or useful life of the asset |
Intangible Assets | Intangible Assets Intangible assets represent the excess of cost over the estimated fair value of net tangible assets of acquired businesses. Our primary intangible assets are classified as either goodwill, expiration lists, non-compete non-compete non-compete non-compete We review all of our intangible assets for impairment periodically (at least annually for goodwill) and whenever events or changes in business circumstances indicate that the carrying value of the assets may not be recoverable. We perform such impairment reviews at the division (i.e., reporting unit) level with respect to goodwill and at the business unit level for amortizable intangible assets. In reviewing intangible assets, if the fair value were less than the carrying amount of the respective (or underlying) asset, an indicator of impairment would exist and further analysis would be required to determine whether or not a loss would need to be charged against current period earnings as a component of amortization expense. Based on the results of impairment reviews in 2017, 2016 and 2015, we wrote off $6.2 million, $1.8 million and $11.5 million, respectively, of amortizable intangible assets primarily related to prior year acquisitions of our brokerage segment, which is included in amortization expense in the accompanying consolidated statement of earnings. The determinations of impairment indicators and fair value are based on estimates and assumptions related to the amount and timing of future cash flows and future interest rates. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein. |
Income Taxes | Income Taxes Our tax rate reflects the statutory tax rates applicable to our taxable earnings and tax planning in the various jurisdictions in which we operate. Significant judgment is required in determining the annual effective tax rate and in evaluating uncertain tax positions. We report a liability for unrecognized tax benefits resulting from uncertain tax positions taken or expected to be taken in our tax return. We evaluate our tax positions using a two-step Uncertain tax positions are measured based upon the facts and circumstances that exist at each reporting period and involve significant management judgment. Subsequent changes in judgment based upon new information may lead to changes in recognition, derecognition and measurement. Adjustments may result, for example, upon resolution of an issue with the taxing authorities, or expiration of a statute of limitations barring an assessment for an issue. We recognize interest and penalties, if any, related to unrecognized tax benefits in our provision for income taxes. Tax law requires certain items to be included in our tax returns at different times than such items are reflected in the financial statements. As a result, the annual tax expense reflected in our consolidated statements of earnings is different than that reported in our tax returns. Some of these differences are permanent, such as expenses that are not deductible in our tax returns, and some differences are temporary and reverse over time, such as depreciation expense and amortization expense deductible for income tax purposes. Temporary differences create deferred tax assets and liabilities. Deferred tax liabilities generally represent tax expense recognized in the financial statements for which a tax payment has been deferred, or expense which has been deducted in the tax return but has not yet been recognized in the financial statements. Deferred tax assets generally represent items that can be used as a tax deduction or credit in tax returns in future years for which a benefit has already been recorded in the financial statements. We establish or adjust valuation allowances for deferred tax assets when we estimate that it is more likely than not that future taxable income will be insufficient to fully use a deduction or credit in a specific jurisdiction. In assessing the need for the recognition of a valuation allowance for deferred tax assets, we consider whether it is more likely than not that some portion, or all, of the deferred tax assets will not be realized and adjust the valuation allowance accordingly. We evaluate all significant available positive and negative evidence as part of our analysis. Negative evidence includes the existence of losses in recent years. Positive evidence includes the forecast of future taxable income by jurisdiction, tax-planning |
Fair Value of Financial Instruments | Fair Value of Financial Instruments Fair value accounting establishes a framework for measuring fair value, which is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (i.e., an exit price). This framework includes a fair value hierarchy that prioritizes the inputs to the valuation technique used to measure fair value. The classification of a financial instrument within the valuation hierarchy is based upon the transparency of inputs to the valuation of an asset or liability on the measurement date. The three levels of the hierarchy in order of priority of inputs to the valuation technique are defined as follows: • Level 1 - Valuations are based on unadjusted quoted prices in active markets for identical financial instruments; • Level 2 - Valuations are based on quoted market prices, other than quoted prices included in Level 1, in markets that are not active or on inputs that are observable either directly or indirectly for the full term of the financial instrument; and • Level 3 - Valuations are based on pricing or valuation techniques that require inputs that are both unobservable and significant to the overall fair value measurement of the financial instrument. Such inputs may reflect management’s own assumptions about the assumptions a market participant would use in pricing the financial instrument. The level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measure in its entirety. The carrying amounts of financial assets and liabilities reported in the accompanying consolidated balance sheet for cash and cash equivalents, restricted cash, premiums and fees receivable, premiums payable to underwriting enterprises, accrued salaries and bonuses, accounts payable and other accrued liabilities, unearned fees and income taxes payable, at December 31, 2017 and 2016, approximate fair value because of the short-term duration of these instruments. See Note 3 to these consolidated financial statements for the fair values related to the establishment of intangible assets and the establishment and adjustment of earnout payables. See Note 7 to these consolidated financial statements for the fair values related to borrowings outstanding at December 31, 2017 and 2016 under our debt agreements. See Note 12 to these consolidated financial statements for the fair values related to investments at December 31, 2017 and 2016 under our defined benefit pension plan. |
Litigation | Litigation We are the defendant in various legal actions related to claims, lawsuits and proceedings incident to the nature of our business. We record liabilities for loss contingencies, including legal costs (such as fees and expenses of external lawyers and other service providers) to be incurred, when it is probable that a liability has been incurred on or before the balance sheet date and the amount of the liability can be reasonably estimated. We do not discount such contingent liabilities. To the extent recovery of such losses and legal costs is probable under our insurance programs, we record estimated recoveries concurrently with the losses recognized. Significant management judgment is required to estimate the amounts of such contingent liabilities and the related insurance recoveries. In order to assess our potential liability, we analyze our litigation exposure based on available information, including consultation with outside counsel handling the defense of these matters. As these liabilities are uncertain by their nature, the recorded amounts may change due to a variety of different factors, including new developments in, or changes in approach, such as changing the settlement strategy as applicable to each matter. |
Retention bonus arrangements | Retention bonus arrangements In connection with the hiring and retention of both new talent and experienced personnel, including our senior management, brokers and other key personnel, we have entered into various agreements with key employees setting up the conditions for the cash payment of certain retention bonuses. These bonuses are an incentive for these employees to remain with the company, for a fixed period of time, to allow us to capitalize on their knowledge and experience. We have various forms of retention bonus arrangements; some are paid up front and some are paid at the end of the term, but all are contingent upon successfully completing a minimum period of employment. A retention bonus that is paid to an employee upfront that is contingent on a certain minimum period of employment, will be initially classified as a prepaid asset and amortized to compensation expense as the future services are rendered over the duration of the stay period. A retention bonus that is paid to an employee at the end of the term that is contingent on a certain minimum period of employment, will be accrued as a liability through compensation expense as the future services are rendered over the duration of the stay period. If an employee leaves prior to the required time frame to earn the retention bonus outright, then all or any portion that is ultimately unearned or refundable, and recovered by the company if prepaid, is forfeited and reversed through compensation expense. |
Stock-Based Compensation | Stock-Based Compensation We have several employee equity-settled and cash-settled share-based compensation plans. Equity-settled share-based payments to employees include grants of stock options, performance stock units and restricted stock units and are measured based on estimated grant date fair value. We have elected to use the Black-Scholes option pricing model to determine the fair value of stock options on the dates of grant. Performance stock units are measured on the probable outcome of the performance conditions applicable to each grant. Restricted stock units are measured based on the fair market values of the underlying stock on the dates of grant. Shares are issued on the vesting dates net of the minimum statutory tax withholding requirements, as applicable, to be paid by us on behalf of our employees. As a result, the actual number of shares issued will be fewer than the actual number of performance stock units and restricted stock units outstanding. Furthermore, we record the liability for withholding amounts to be paid by us as a reduction to additional paid-in Cash-settled share-based payments to employees include awards under our Performance Unit Program and stock appreciation rights. The fair value of the amount payable to employees in respect of cash-settled share-based payments is recognized as compensation expense, with a corresponding increase in liabilities, over the vesting period. The liability is remeasured at each reporting date and at settlement date. Any changes in fair value of the liability are recognized as compensation expense. We recognize share-based compensation expense over the requisite service period for awards expected to ultimately vest. Forfeitures are estimated on the date of grant and revised if actual or expected forfeiture activity differs from original estimates. |
Employee Stock Purchase Plan | Employee Stock Purchase Plan We have an employee stock purchase plan (which we refer to as the ESPP), under which the sale of 8.0 million shares of our common stock has been authorized. Eligible employees may contribute up to 15% of their compensation towards the quarterly purchase of our common stock at a purchase price equal to 95% of the lesser of the fair market value of our common stock on the first business day or the last business day of the quarterly offering period. Eligible employees may annually purchase shares of our common stock with an aggregate fair market value of up to $25,000 (measured as of the first day of each quarterly offering period of each calendar year), provided that no employee may purchase more than 2,000 shares of our common stock under the ESPP during any calendar year. At December 31, 2017, 7.2 million shares of our common stock was reserved for future issuance under the ESPP. |

We currently believe the most significant impact relates to our real estate operating leases and the related recognition of right-of-use |
Cash Receipts and Cash Payments | Cash Receipts and Cash Payments In August 2016, the FASB issued ASU No. 2016-15, (ASU 2016-15). ASU 2016-15 The adoption of this guidance resulted in a change to our classification whereby contingent payments on acquisitions that are up to the acquisition date fair value have been presented in financing activities and those payments in excess of the acquisition date fair value have been presented in operating activities. Historically these payments have all been included in investing activities. Accordingly, in our 2016 consolidated statement of cash flows, we reclassified $22.8 million and $45.5 million of payments from investing activities to operating activities and financing activities, respectively, to conform to the current year presentation. In our 2015 consolidated statement of cash flows, we reclassified $12.1 million and $21.8 million of payments from investing activities to operating activities and financing activities, respectively, to conform to the current year presentation. The modifications can be seen in our statement of cash flows. |
