Organization, Consolidation and Presentation of Financial Statements [Abstract] | |
Nature of Operations and Basis of Presentation | 1. Nature of Operations and Basis of Presentation Arthur J. Gallagher & Co. and its subsidiaries, collectively referred to herein as we, our, us or the company, provide insurance brokerage and risk management services to a wide variety of commercial, industrial, institutional and governmental organizations through three reportable segments. Commission and fee revenue generated by the brokerage segment is primarily related to the negotiation and placement of insurance for our clients. Fee revenue generated by the risk management segment is primarily related to claims management, information management, risk control consulting (loss control) services and appraisals in the property/casualty market. Investment income and other revenue are generated from our premium financing operations and our investment portfolio, which includes invested cash and restricted funds, as well as clean energy and other investments. We are headquartered in Rolling Meadows, Illinois, have operations in 34 countries and offer client-service capabilities in more than 150 countries globally through a network of correspondent insurance brokers and consultants. We have prepared the accompanying unaudited consolidated financial statements pursuant to the rules and regulations of the Securities and Exchange Commission. Certain information and footnote disclosures normally included in annual financial statements have been omitted pursuant to such rules and regulations. The unaudited consolidated financial statements included herein are, in the opinion of management, prepared on a basis consistent with our audited consolidated financial statements for the year ended December 31, 2016, except as disclosed in Note 2, and include all normal recurring adjustments necessary for a fair presentation of the information set forth. The quarterly results of operations are not necessarily indicative of the results of operations to be reported for subsequent quarters or the full year.

Accounting Changes and Error Corrections [Abstract] | |
Effect of New Accounting Pronouncements | 2. Effect of New Accounting Pronouncements Hedge Accounting In August 2017, the Financial Accounting Standards Board (which we refer to as the FASB) issued Accounting Standards Update (which we refer to as ASU) No. 2017-12, last-of-layer 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, 2016-09). 2016-09 Cash Receipts and Cash Payments In August 2016, the FASB issued ASU No. 2016-15, 2016-15). 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 September 30, 2016 consolidated statement of cash flows, we reclassified $19.5 million and $41.7 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, Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, pre-2018 A full assessment to determine the impacts of the new accounting standard has been performed. We are currently implementing new accounting and operational processes which are a result of the new guidance and are analyzing the impact of these changes. 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 material 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 commissions 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 pre-tax |

Business Combinations | 3. Business Combinations During the nine-month period ended September 30, 2017, we acquired substantially all of the net assets of the following firms in exchange for our common stock and/or cash.

The transaction was subject to customary closing conditions and closed on October 4, 2017. Common shares issued in connection with acquisitions are valued at closing market prices as of the effective date of the applicable acquisition. 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- During the three-month periods ended September 30, 2017 and 2016, we recognized $4.9 million and $4.3 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. During the nine-month periods ended September 30, 2017 and 2016, we recognized $15.2 million and $12.5 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 the three-month periods ended September 30, 2017 and 2016, we recognized $5.7 million of expense and $0.2 million of income, respectively, related to net adjustments in the estimated fair value of earnout obligations in connection with revised projections of future performance for 31 and 27 acquisitions, respectively. In addition, during the nine-month periods ended September 30, 2017 and 2016, we recognized $12.3 million and $8.7 million of expense, respectively, related to net adjustments in the estimated fair value of earnout obligations in connection with revised projections of future performance for 89 and 77 acquisitions, respectively. The aggregate amount of maximum earnout obligations related to acquisitions was $563.9 million as of September 30, 2017, of which $274.3 million was recorded in our consolidated balance sheet as of September 30, 2017, 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 and non-compete Provisional estimates of fair value are established at the time of each 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%, respectively, for our 2016 and 2017 acquisitions 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 2016 and 2017 acquisitions for which valuations were performed in 2017. The fair value of non-compete non-compete Expiration lists, non-compete non-compete Of the $188.9 million of expiration lists and $2.8 million of non-compete Our consolidated financial statements for the nine-month period ended September 30, 2017 include the operations of the acquired entities from their respective acquisition dates.

Stock Option Plans | 8. 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. 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 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 at September 30, 2017. To the extent necessary to be qualified performance-based compensation under Section 162(m) of the Internal Revenue Code (which we refer to as the IRC): (i) the maximum number of shares with respect to which options or stock appreciation rights or a combination thereof that may be granted during any calendar year to any person is 200,000; (ii) the maximum number of shares with respect to which awards other than options or stock appreciate rights that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code and are denominated in shares of common stock that may be earned pursuant to such awards granted during any calendar year to any person under the LTIP will be 200,000; and (iii) the maximum amount that may be payable with respect to all awards that are intended to qualify as “performance-based compensation” under Section 162(m) of the Code and are denominated in cash granted during any calendar year to any person under the LTIP is $5.0 million. 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 2,576,700 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 2019, 2020 and 2021, respectively. The 2017 and 2016 options expire seven years from the date of grant, or earlier in the event of certain terminations of employment. For certain of our executive officers age 55 or older, stock options awarded in 2017 and 2016 are no longer subject to forfeiture upon such officers’ departure from the company after two years from the date of grant. During the three-month periods ended September 30, 2017 and 2016, we recognized $4.4 million and $3.8 million, respectively, of compensation expense related to our stock option grants. During the nine-month periods ended September 30, 2017 and 2016, we recognized $12.9 million and $10.9 million, respectively, of compensation expense related to our stock option grants. For purposes of expense recognition, 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: 2017 2016 Expected dividend yield 2.8 % 3.0 % Expected risk-free interest rate 2.3 % 1.6 % Volatility 27.2 % 27.7 % Expected life (in years) 5.0 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 (in millions, except exercise price and year data): Nine-month period ended September 30, 2017 Weighted Average Weighted Remaining Shares Average Contractual Aggregate Under Exercise Term Intrinsic Option Price (in years) Value Beginning balance 10.3 $ 41.40 Granted 1.6 56.85 Exercised (1.2 ) 32.58 Forfeited or canceled — — Ending balance 10.7 $ 44.83 4.16 $ 179.4 Exercisable at end of period 2.7 $ 37.76 1.98 $ 63.7 Ending vested and expected to vest 10.5 $ 44.75 4.13 $ 177.0 Options with respect to 16.1 million shares (less any shares of restricted stock issued under the LTIP—see Note 10 to these unaudited consolidated financial statements) were available for grant under the LTIP at September 30, 2017. The total intrinsic value of options exercised during the nine-month periods ended September 30, 2017 and 2016 was $28.3 million and $14.9 million, respectively. As of September 30, 2017, we had approximately $47.4 million of total unrecognized compensation expense related to nonvested options. We expect to recognize that cost over a weighted average period of approximately four years.

Deferred Compensation | 9. 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 the 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 and 2016, the compensation committee approved $14.0 million and $10.1 million, respectively, of awards in the aggregate to certain key executives under the DEPP that were contributed to the rabbi trust in first quarter 2017 and 2016, respectively. 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 and 2016 awards. During the three-month periods ended September 30, 2017 and 2016, we charged $2.6 million and $2.1 million, respectively, to compensation expense related to these awards. During the nine-month periods ended September 30, 2017 and 2016, we charged $7.0 million and $5.5 million, respectively, to compensation expense related to these awards. In the first quarter of 2017 and in the second quarter of 2016, the compensation committee approved $4.0 million and $13.6 million, respectively, of awards under the sub-plans nine-month sub-plans At September 30, 2017 and December 31, 2016, we recorded $58.4 million (related to 2.7 million shares) and $46.8 million (related to 2.4 million shares), respectively, of unearned deferred compensation as a 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 September 30, 2017 and December 31, 2016 was $169.0 million and $125.5 million, respectively. During the nine-month period ended September 30, 2017, there were no distributions under the DEPP. During the nine-month period ended September 30, 2016, cash and equity awards with an aggregate fair value of $7.0 million were vested and distributed to executives under the Age 62 Plan.

Restricted Stock, Performance Share and Cash Awards | 10. Restricted Stock, Performance Share and Cash Awards Restricted Stock Awards As discussed in Note 8 to these unaudited 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 September 30, 2017, 4.0 million shares were available for grant under the LTIP for such awards. In the first quarter of each of 2017 and 2016, we granted 477,500 and 466,600 restricted stock units, respectively, to employees under the LTIP, with an aggregate fair value of $26.8 million and $20.4 million, respectively, at the date of grant. These 2017 and 2016 awards of restricted stock units vest as follows: 477,500 units granted in first quarter 2017 and 466,600 units granted in first quarter 2016, vest in full based on continued employment through March 16, 2021 and March 11, 2020, respectively. For certain of our executive officers age 55 or older, restricted stock units awarded in 2017 and 2016 are not subject to forfeiture upon such officers’ departure from the company after two years from the date of grant. 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 the three-month periods ended September 30, 2017 and 2016, we recognized $4.7 million and $4.2 million, respectively, to compensation expense related to restricted stock unit awards granted in 2007 through 2017. During the nine-month periods ended September 30, 2017 and 2016, we recognized $15.2 million and $14.2 million, respectively, to compensation expense related to restricted stock unit awards granted in 2007 through 2017. The total intrinsic value of unvested restricted stock units at September 30, 2017 and 2016 was $107.6 million and $79.7 million, respectively. During the nine-month periods ended September 30, 2017 and 2016, equity awards (including accrued dividends) with an aggregate fair value of $23.3 million and $14.2 million was vested and distributed to employees under this plan. Performance Share Awards On March 16, 2017 and March 17, 2016, pursuant to the LTIP, the compensation committee approved 86,250 and 72,900, respectively of provisional performance unit awards, with an aggregate fair value of $4.9 million and $3.2 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. In 2016, these awards were subject to a 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. The Program consists of a one-year two-year On March 17, 2016, pursuant to the Program, the compensation committee approved provisional cash awards of $17.4 million in the aggregate for future grant to our officers and key employees that are denominated in units (397,000 units in the aggregate), each of which was equivalent to the value of one share of our common stock on the date the provisional awards were approved. Terms of the 2016 provisional awards were similar to the terms of the 2017 provisional awards. Based on our performance for 2016, we granted 383,000 units under the Program in first quarter 2017 that will fully vest on January 1, 2019. During the three-month period ended September 30, 2017, we recognized $2.6 million to compensation expense related to these awards. During the nine-month period ended September 30, 2017, we recognized $7.9 million to compensation expense related to these awards. We did not recognize any compensation expense during 2016 related to the 2016 awards. On March 11, 2015, pursuant to the Program, the compensation committee approved provisional cash awards of $14.6 million in the aggregate for future grant to our officers and key employees that are denominated in units (315,000 units in the aggregate), each of which was equivalent to the value of one share of our common stock on the date the provisional awards were approved. Terms of the 2015 provisional awards were similar to the terms of the 2016 provisional awards. Based on our performance for 2015, we granted 294,000 units under the Program in first quarter 2016 that will fully vest on January 1, 2018. During the three-month periods ended September 30, 2017 and 2016, we recognized $2.0 million and $1.7 million, respectively, to compensation expense related to these awards. During the nine-month On March 12, 2014, pursuant to the Program, the compensation committee approved provisional cash awards of $10.8 million in the aggregate for future grant to our officers and key employees that are denominated in units (229,000 units in the aggregate), each of which was equivalent to the value of one share of our common stock on the date the provisional awards were approved. Terms of the 2014 provisional awards were similar to the terms of the 2015 provisional awards.

Derivative Instruments and Hedging Activities Disclosure [Abstract] | |
Derivatives and Hedging Activity | 12. 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 we earn revenues, pay expenses, or enter into monetary intercompany transfers denominated in a currency that differs from our functional currency, or other transactions that are denominated in a currency other than our 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 September 30, 2017.

Outstanding purchase commitments in the table above include $0.7 million related to expenditures on our new corporate headquarters. 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.

See the Off-Balance Since January 1, 2002, we have acquired 450 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 2014 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 operating results of the acquired entities over a two- Off-Balance - At September 30, 2017, we had posted two letters of credit totaling $9.7 million, in the aggregate, related to our self-insurance rent-a-captive Litigation, Regulatory and Taxation Matters - non-compete In July 2014, we were named in a lawsuit that 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 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 complaints and disallowed any further opportunity to amend or refile. Nalco appealed this ruling to the Federal Circuit Court and we are expecting a ruling within the next few months. 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 Internal Revenue Service (IRS). Additionally, the IRS has initiated audits for the 2012 tax year of over 100 of the micro-captive insurance companies 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 its audits of our clients, we are not able to reasonably estimate the amount of any potential loss in connection with this investigation.

Segment Reporting [Abstract] | |
Segment Information | 15. Segment Information We have three reportable segments: brokerage, risk management and corporate. The brokerage segment is primarily comprised of our retail and wholesale insurance brokerage operations. The brokerage segment generates revenues through commissions paid by insurance underwriters and through fees charged to our clients. Our brokers, agents and administrators act as intermediaries between insurers and their customers and we do not generally assume underwriting risks. The 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 insurance companies 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 The corporate segment manages our clean energy and other investments. In addition, the corporate segment reports the financial information related to our debt, and certain corporate and acquisition-related activities. 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 country statutory rates. Reported operating results by segment would change if different methods were applied. Financial information relating to our segments for the three-month and nine-month periods ended September 30, 2017 and 2016 is as follows (in millions): Three-month period Nine-month period ended September 30, ended September 30, 2017 2016 2017 2016 Brokerage Total revenues $ 953.7 $ 877.6 $ 2,830.3 $ 2,642.2 Earnings before income taxes $ 161.6 $ 149.1 $ 491.8 $ 427.3 Identifiable assets at September 30, 2017 and 2016 $ 10,275.9 $ 8,972.7 Risk Management Total revenues $ 200.2 $ 176.7 $ 571.5 $ 532.5 Earnings before income taxes $ 27.8 $ 21.5 $ 73.6 $ 67.9 Identifiable assets at September 30, 2017 and 2016 $ 733.0 $ 679.6 Corporate Total revenues $ 430.6 $ 428.0 $ 1,158.8 $ 1,035.1 Loss before income taxes $ (92.7 ) $ (75.7 ) $ (269.4 ) $ (207.1 ) Identifiable assets at September 30, 2017 and 2016 $ 1,801.5 $ 1,548.0 |

Historically these payments have all been included in investing activities. Accordingly, in our September 30, 2016 consolidated statement of cash flows, we reclassified $19.5 million and $41.7 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. |

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 material 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: |
Segment Reporting | 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 commissions 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 pre-tax |
