(7 of 14)

Interest and banking costs and debt - At December 31, 2016, Gallagher had $2,450.0 million of borrowings from private placements, $278.0 million of short-term borrowings under its line of credit facility and $125.6 million outstanding under a revolving loan facility that provides funding for premium finance receivables, which are fully collateralized by the underlying premiums held by insurance carriers and as such are excluded from our debt covenant computations. On December 1, 2016, Gallagher entered into a note purchase agreement for a private placement of $100.0 million of senior unsecured notes. Proceeds were primarily used to fund the $50.0 million of private placement debt that matured on November 30, 2016 and partially fund acquisitions.

Clean energy - Consists of the operating results related to our investments in 34 clean coal production plants and royalty income from clean coal licenses related to Chem-Mod LLC. Additional information regarding these results is available in the "CFO Commentary" at ajg.com/IR.

Acquisition costs - Consists mostly of external professional fees and other due diligence costs related to acquisitions.

Corporate - Consists of overhead allocations mostly related to corporate staff compensation.

Income Taxes

Gallagher allocates the provision for income taxes to its Brokerage and Risk Management segments using the local country statutory rates. Gallagher's consolidated effective tax rate for the quarters ended December 31, 2016 and 2015 was (46.8)% and (140.1)%, respectively, which was lower than the statutory rate due to the amount of IRC Section 45 tax credits earned.

At-the-market equity program - Gallagher has an at-the-market equity program under which up to $15.6 million of its common stock remaining in the program may be sold through Morgan Stanley & Co. LLC as sales agent. During fourth quarter 2016, Gallagher did not sell any shares of its common stock under the program.

Balance Sheet Reclassifications

In first quarter 2016, Gallagher adopted new accounting guidance related to the presentation of both debt issuance costs and income taxes in the consolidated balance sheet. The new debt issuance costs guidance requires such costs to be presented in the balance sheet as a direct deduction from the associated debt liability. The new income tax guidance requires that deferred tax assets and liabilities be classified as noncurrent on the balance sheet rather than being separated into current and noncurrent components. The new guidance has been applied on a retrospective basis. Accordingly, Gallagher reclassified debt issuance costs of $3.3 million included in Other noncurrent assets to Corporate related borrowings - noncurrent in its consolidated balance sheet as of December 31, 2015. Gallagher also reclassified the current deferred taxes to noncurrent in its consolidated balance sheet as of December 31, 2015, which increased Noncurrent deferred income taxes by $122.1 million and increased Other noncurrent liabilities by $4.6 million. In addition, in fourth quarter 2016, Gallagher reclassified work in process type assets related to its new corporate headquarters and other projects of $46.3 million included in Other noncurrent assets to Fixed assets in its consolidated balance sheet as of December 31, 2015.

Instead, incentive compensation determinations for executive officers are made on the basis of revenue and EBITAC (defined as earnings before interest, taxes, amortization and change in estimated earnout payables) for the combined Brokerage and Risk Management segments. Certain reclassifications have been made to the prior year amounts reported in this press release in order to conform them to the current year presentation.

Adjusted Non-GAAP presentation - Gallagher believes that the adjusted non-GAAP presentations of the current and prior year information, presented in this earnings release, provide stockholders and other interested persons with useful information regarding certain financial metrics of Gallagher that may assist such persons in analyzing Gallagher's operating results as they develop a future earnings outlook for Gallagher. The after-tax amounts related to the adjustments were computed using the normalized effective tax rate for each respective period. See pages 13 and 14 for a reconciliation of the adjustments made to income taxes.


    --  Adjusted revenues and expenses - Revenues, compensation expense and
        operating expense, respectively, each adjusted to exclude the following:
        --  Net gains realized from sales of books of business, which are
            primarily net proceeds received related to sales of books of
            business and other divestiture transactions.
        --  Acquisition integration costs, which include costs related to
            certain of our large acquisitions, outside the scope of our usual
            tuck-in strategy, not expected to occur on an ongoing basis in the
            future once we fully assimilate the applicable acquisition.  These
            costs are typically associated with redundant workforce, extra lease
            space, duplicate services and external costs incurred to assimilate
            the acquisition with our IT related systems.
        --  Workforce related charges, which primarily include severance costs
            related to employee terminations and other costs associated with
            redundant workforce.
        --  Lease termination related charges, which primarily include costs
            related to terminations of real estate leases and abandonment of
            leased space.
        --  Acquisition related adjustments, which include change in estimated
            acquisition earnout payables adjustments, impacts of acquisition
            valuation true-ups, impairment charges and acquisition related
            compensation charges.
        --  The impact of foreign currency translation, as applicable.  The
            amounts excluded with respect to foreign currency translation are
            calculated by applying current year foreign exchange rates to the
            same periods in the prior year.
    --  Adjusted ratios - Adjusted compensation expense and adjusted operating
        expense, respectively, each divided by adjusted revenues.

Non-GAAP Earnings Measures


    --  EBITDAC and EBITDAC margin - EBITDAC is net earnings before interest,
        income taxes, depreciation, amortization and the change in estimated
        acquisition earnout payables and EBITDAC margin is EBITDAC divided by
        total revenues. These measures for the Brokerage and Risk Management
        segments provide a meaningful representation of Gallagher's operating
        performance and, for the overall business, provide a meaningful way to
        measure its financial performance on an ongoing basis.

(9 of 14)


    --  Adjusted EBITDAC and Adjusted EBITDAC Margin - Adjusted EBITDAC is
        EBITDAC adjusted to exclude net gains realized from sales of books of
        business, acquisition integration costs, workforce related charges,
        lease termination related charges, acquisition related adjustments and
        the period-over-period impact of foreign currency translation, as
        applicable and Adjusted EBITDAC margin is Adjusted EBITDAC divided by
        total adjusted revenues (defined above). These measures for the
        Brokerage and Risk Management segments provide a meaningful
        representation of Gallagher's operating performance, and are also
        presented to improve the comparability of our results between periods by
        eliminating the impact of the items that have a high degree of
        variability.
    --  Adjusted EPS for the Brokerage and Risk Management segments - Net
        earnings adjusted to exclude the after-tax impact of net gains realized
        from sales of books of business, acquisition integration costs, the
        impact of foreign currency translation, workforce related charges, lease
        termination related charges and acquisition related adjustments divided
        by diluted weighted average shares outstanding. This measure provides a
        meaningful representation of Gallagher's operating performance (and as
        such should not be used as a measure of Gallagher's liquidity), and is
        also presented to improve the comparability of our results between
        periods by eliminating the impact of the items that have a high degree
        of variability.

Organic Revenues (a non-GAAP measure) - For the Brokerage segment, organic change in base commission and fee revenues excludes the first twelve months of net commission and fee revenues generated from acquisitions and the net commission and fee revenues related to operations disposed of in each year presented. These commissions and fees are excluded from organic revenues in order to help interested persons analyze the revenue growth associated with the operations that were a part of Gallagher in both the current and prior year. In addition, change in base commission and fee revenue organic growth excludes the period-over-period impact of foreign currency translation. For the Risk Management segment, organic change in fee revenues excludes the first twelve months of fee revenues generated from acquisitions and the fee revenues related to operations disposed of in each year presented. In addition, change in organic growth excludes the impact of run-off of the New South Wales Workers' Compensation Scheme and other closed down operations and the period-over-period impact of foreign currency translation to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability or are due to the limited-time nature of these revenue sources.

These revenue items are excluded from organic revenues in order to determine a comparable, but non-GAAP, measurement of revenue growth that is associated with the revenue sources that are expected to continue in the current year and beyond. Gallagher has historically viewed organic revenue growth as an important indicator when assessing and evaluating the performance of its Brokerage and Risk Management segments. Gallagher also believes that using this non-GAAP measure allows readers of our financial statements to measure, analyze and compare the growth from its Brokerage and Risk Management segments in a meaningful and consistent manner.

Reconciliation of Non-GAAP Information Presented to GAAP Measures - This press release includes tabular reconciliations to the most comparable GAAP measures, as follows: for EBITDAC (on pages 11 and 12), for adjusted revenues, adjusted EBITDAC and adjusted diluted net earnings per share (on pages 2 and 3), for organic revenue measures (on pages 4 and 6, respectively, for the Brokerage and Risk Management segments), for adjusted compensation and operating expenses and adjusted EBITDAC margin (on pages 5, 6 and 7, respectively, for the Brokerage and Risk Management segments). Reported compensation and operating expense ratios can also be found in the "Supplemental Quarterly Data" available at ajg.com/IR.
