Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2012

Nature of Operations

Nature of Operations - Arthur J. Gallagher & Co. and its subsidiaries, collectively referred to herein as we, our or us, provide insurance brokerage and risk management services to a wide variety of commercial, industrial, institutional and governmental organizations through two reportable operating 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 is generated from our investment portfolio, which includes invested cash and restricted funds, as well as tax-advantaged, clean energy and other investments. We are headquartered in Itasca, Illinois, have operations in 18 countries and offer client-service capabilities in more than 140 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 variable interest entity (which we refer to as 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.

Certain reclassifications have been made to the amounts reported in prior years’ consolidated financial statements in order to conform to the current year presentation.

In the preparation of our consolidated financial statements as of December 31, 2012, 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 generally accepted accounting principles requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. 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, fees and investment income.

We recognize commission 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 supplemental commission revenues using internal data and information received from insurance carriers that allows us to reasonably estimate the supplemental commissions earned in the period. A supplemental commission is a commission paid by an insurance carrier that is above the base commission paid, is determined by the insurance carrier based on historical performance criteria, and is established annually in advance of the contractual period. We recognize contingent commissions and commissions on premiums directly billed by insurance carriers as revenue when we have obtained the data necessary to reasonably determine such amounts. Typically, we cannot reasonably determine these types of commission revenues until we have received the cash or the related policy detail or other carrier specific information from the insurance carrier. A contingent commission is a commission paid by an insurance carrier based on the overall profit and/or volume of the business placed with that insurance carrier during a particular calendar year and is determined after the contractual period. Commissions on premiums billed directly by insurance carriers to the insureds generally relate to a large number of property/casualty insurance policy transactions, each with small premiums, and comprise a substantial portion of the revenues generated by our employee benefit brokerage operations. Under these direct bill arrangements, the insurance carrier 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. Fee revenues generated from the risk management segment relate to third party claims administration, loss control and other risk management consulting services, which we provide over a period of time, typically one year. 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.

We deduct brokerage expense from gross revenues in our determination of our total revenues. Brokerage expense represents commissions paid to sub-brokers related to the placement of certain business by our brokerage segment. We recognize this expense in the same manner as commission revenues.

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 $4.0 million and $5.2 million at December 31, 2012 and 2011, 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 $6.6 million and $4.8 million at December 31, 2012 and 2011, respectively. We establish the allowance for estimated policy cancellations through a charge to revenues and the allowance for doubtful accounts through a charge to other 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.

Investment income primarily includes interest and dividend income, which is accrued as it is earned. Gains on books of business sales represent one-time gains related to sales of brokerage related businesses, which are primarily recognized on a cash received basis. Revenues from clean coal activities include revenues from consolidated clean coal production plants, royalty income from clean coal licenses and income (loss) related to unconsolidated clean coal production plants, all of which are recognized as earned. Revenues from consolidated clean coal production plants represent sales of refined coal. Royalty income from clean coal licenses represents fee income related to the use of clean coal technologies. Income (loss) from unconsolidated clean coal production plants includes income (losses) related to our equity portion of the pretax results of the clean coal production plants and production based installment sale income from majority investors. Other net revenues (loss) primarily consist of our equity portions of the earnings from our investment in four venture capital funds.

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 obligations based on the estimated costs to provide these future services to former clients. This liability is 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 (at least annually) the adequacy of this liability and will make adjustments as necessary.

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 insurance carriers. 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 insurance and reinsurance companies. 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, 2012.

Related to our third party administration business, 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 insurance and reinsurance companies in the accompanying consolidated balance sheet.

Derivative Instruments

Derivative Instruments - 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 significant portion of our future foreign currency disbursements through various future payment dates. To mitigate the counterparty credit risk we only enter into contracts with carefully selected 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 British Pound Sterling 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 compensation and operating expenses. We do not use derivatives for trading or speculative purposes.

Investments

Investments - We have a management investment committee that meets four to six times per year to review the valuation of our investments. For investments that do not have quoted market prices, we use various valuation techniques to estimate fair value and proactively look for indicators of impairment. Factors that may indicate that an impairment could exist include, but are not limited to, reductions or changes to dividend payments, sustained operating losses or a trend of poor operating performance, recent refinancings or recapitalizations, unfavorable press reports, significant customer or revenue loss, litigation, losses by other companies in a similar industry, overall economic conditions, management changes and significant changes in strategy. In addition, in cases where the ultimate value of an investment is directly dependent on us for future financial support, we assess our willingness and intent to provide future funding in determining impairment.

If an indicator of impairment exists, we compare the investment’s carrying value to an estimate of its fair value. To estimate the fair value of our equity-method investments, we compare values established in recent recapitalizations or appraisals conducted by third parties. In some cases, no such recapitalizations or appraisals exist and we must perform our own valuations. This also requires us to exercise significant judgment. Even if impairment indicators exist, no impairment may be required if the estimated fair value is not less than the current carrying value or the decline in value is determined to be temporary and we have no intent to sell the investment, and it is more likely than not that we will not be required to sell the investment prior to a recovery in value. When we determine that an impairment is required, we record the impairment as a realized loss against current period earnings.

Both the process to review for indicators of impairment and, if such indicators exist, the method to compute the amount of impairment incorporates quantitative data and qualitative criteria including the receipt of new information that can significantly change the decision about the valuation of an investment in a short period of time. The determination of whether an impairment is required is necessarily a matter of subjective judgment. The timing and amount of realized losses reported in earnings could vary if management’s conclusions were different.

Because of the inherent risk of investments, we can make no assurances that there will not be impairments in the future should economic and other conditions change.

Premium Financing

Premium Financing - Two 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 considered delinquent after seven days of the payment due date. Generally, 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 interest “level-yield” method. Unearned interest related to contracts receivable is included in the receivable balance in the accompanying consolidated balance sheet. The outstanding contracts receivable balance was $2.2 million and $2.3 million at December 31, 2012 and 2011, 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
Computer equipment	Three to five years
Furniture and fixtures	Three to ten years
Office equipment	Three to ten years
Software	Three to five 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 agreements or trade names. Expiration lists, non-compete agreements and trade names are amortized using the straight-line method over their estimated useful lives (three to fifteen years for expiration lists, three to five years for non-compete agreements and ten to fifteen years for trade names), while goodwill is not subject to amortization. The establishment of goodwill, expiration lists, non-compete agreements and trade names and the determination of estimated useful lives are primarily based on valuations we receive from qualified independent appraisers. The calculations of these amounts are based on estimates and assumptions using historical and pro forma data and recognized valuation methods. Different estimates or assumptions could produce different results. We carry intangible assets at cost, less accumulated amortization, in the accompanying consolidated balance sheet.

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 2012, 2011 and 2010, we wrote off $3.5 million, $4.6 million and $2.3 million, respectively, of amortizable intangible assets related to prior year acquisitions of our brokerage segment. 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 process. The first step involves recognition. We determine whether it is more likely than not that a tax position will be sustained upon tax examination based solely on the technical merits of the position. The technical merits of a tax position are derived from both statutory and judicial authority (legislation and statutes, legislative intent, regulations, rulings and case law) and their applicability to the facts and circumstances of the position. If a tax position does not meet the “more likely than not” recognition threshold, we do not recognize the benefit of that position in the financial statements. The second step is measurement. A tax position that meets the “more likely than not” recognition threshold is measured to determine the amount of benefit to recognize in the financial statements. The tax position is measured as the largest amount of benefit that has a likelihood of greater than 50% of being realized upon ultimate resolution with a taxing authority.

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 the tax returns. Some of these differences are permanent, such as expenses that are not deductible in the 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 strategies that would result in the realization of deferred tax assets and the presence of taxable income in prior carryback years. The underlying assumptions we use in forecasting future taxable income require significant judgment and take into account our recent performance. Such estimates and assumptions could change in the future as more information becomes known which could impact the amounts reported and disclosed herein. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the periods in which temporary differences are deductible or creditable.

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 insurance carriers, accrued salaries and bonuses, accounts payable and other accrued liabilities, unearned fees and income taxes payable, at December 31, 2012 and 2011, approximate fair value because of the short-term duration of these instruments. See Note 3 to our consolidated financial statements for the fair values related to the establishment of intangible assets and the establishment and adjustment of earnout payables. See Note 6 to our consolidated financial statements for the fair values related to borrowings outstanding at December 31, 2012 and 2011 under our debt agreements. See Note 11 to our consolidated financial statements for the fair values related to investments at December 31, 2012 and 2011 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.

Stock-Based Compensation

Stock-Based Compensation - We use the modified-prospective method to account for share-based payments made to employees. Under the modified-prospective method, compensation cost is recognized for all share-based payments granted on or after January 1, 2006 and for all awards granted to employees prior to January 1, 2006 that remained unvested on that date. We use the alternative transition method to determine the accounting of the income tax effects of payments made related to stock-based compensation.

Accounting guidance issued in 2006 related to share-based payments requires that compensation cost be recognized for unvested awards over the period through the date that the employee is no longer required to provide future services to earn the award, rather than over the explicit service period. Accordingly, our accounting policy for 2007 and future stock option grants is to recognize compensation cost to coincide with the date that the employee is eligible to retire, rather than the actual retirement date, for all options granted. Stock options granted after May 15, 2007 no longer contain an accelerated vesting upon retirement provision.

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 4.0 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, 2012, 0.8 million shares of our common stock are reserved for future issuance under the ESPP.

Defined Benefit Pension and Other Postretirement Plans

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 the year in which the changes occur. We use December 31 as the measurement date for our plans’ assets and benefit obligations. See Note 11 to our consolidated financial statements for additional information required to be disclosed related to our defined benefit postretirement plans.
