ITASCA, Ill., Jan. 29, 2013 /PRNewswire/ -- Arthur J. Gallagher & Co. (NYSE: AJG) today reported its financial results for the quarter and year ended December 31, 2012. A printer-friendly format and supplemental quarterly data is available at www.ajg.com. For a description of the non-GAAP measures used to report financial results in this earnings release, please see "Information Regarding Non-GAAP Measures" beginning on page 7.

"We had a strong finish to 2012 and we are well positioned for continued success in 2013," said J. Patrick Gallagher, Jr., Chairman, President and CEO. "In the fourth quarter, our combined Brokerage and Risk Management segments posted 14% growth in adjusted total revenues, 4.6% organic growth in base commission and fee revenues, 17% growth in adjusted EBITDAC and adjusted EBITDAC margins improved by 50 basis points."


    --  Our Brokerage segment had an outstanding quarter.  Adjusted total
        revenues were up 18%, base organic commission and fee revenues grew
        5.2%, adjusted EBITDAC was up 20% and adjusted EBITDAC margins were up
        40 basis points.  We also completed another 21 acquisitions with
        annualized revenues of $76 million, which pushed total acquired
        annualized revenues for all of 2012 to over $230 million.
    --  Our Risk Management segment had an excellent quarter.  Excluding the New
        Zealand earthquake claim-settling unit, which has wrapped up operations,
        adjusted total revenues were up 5%, base organic fees were up 2.9%,
        adjusted EBITDAC was up 6%, adjusted EBITDAC margins improved by 30
        basis points and we hit our targeted adjusted EBITDAC margin of 16%
        while making our planned client-centric investments.
    --  During the fourth quarter, we took actions to contract our global
        workforce by approximately 3%, or 400 middle-office and back-office
        positions.  These actions reflect our investments in productivity
        initiatives and improved technology utilization.  Pretax charges total
        approximately $12.3 million and we expect related future annual
        workforce savings of approximately $35.0 million.  Anticipated to mostly
        offset these future savings will be increased medical costs, reduced
        discount rate on our frozen pension plan, salary increases, increased
        performance-based compensation and increased long-term incentive
        compensation.
    --  We made tremendous progress in rolling-out our clean-energy investments
        during 2012 and now have most of our plants in various stages of ramping
        up production.  Our clean energy investments earned nearly $33 million
        in 2012 and could be more than double that in 2013.  These additional
        earnings will be used to continue our M&A strategy in our core brokerage
        and risk management operations.

"As we look towards 2013, we see a rate environment that is still showing signs of firming in many lines, clients that are finding ways to grow their businesses even in these uncertain times, a strong M&A pipeline, and an operating environment where we can control our costs and improve our productivity. Gallagher's sales and high-quality service culture is thriving and we are in an excellent position for success in 2013."

                 operating expense ratio was
                 0.2 pts higher than the same
                 period in 2011. This year, a
                 new product was introduced
                 that is primarily outsourced,
                 the cost of which flows

                 product, the adjusted fourth
                 quarter operating expense
                 ratio would have been 1.1 pts
                 lower than the same period in
                 2011.  This ratio was
                 primarily impacted by a
                 decrease in professional fees
                 of 0.3 pts and a reduction in
                 business insurance of 0.5 pts.

Gallagher also maintains an unsecured line of credit of $500.0 million that expires July 14, 2014. There were $129.0 million of borrowings outstanding under Gallagher's line of credit facility at December 31, 2012.

Corporate Segment Fourth Quarter Highlights (continued)

Clean energy investments - Gallagher has investments in limited liability companies that own 29 clean coal production plants which produce refined coal using proprietary technologies owned by Chem-Mod. We believe these plants are qualified to receive refined coal tax credits under IRC Section 45. The fourteen plants which were placed in service prior to December 31, 2009 (which we refer to as the 2009 Era Plants) can receive tax credits through 2019 and the fifteen plants which were placed in service prior to December 31, 2011 (which we refer to as the 2011 Era Plants) can receive tax credits through 2021.


    --  2009 Era Plants - Twelve of the fourteen plants are under long-term
        production contracts.  At December 31, 2012, Gallagher's tax-effected
        carrying value of these investments was $4.7 million and collectively
        they could generate approximately $4.5 million of net after-tax earnings
        per quarter through 2019.  Gallagher is currently in negotiations with a
        utility for long-term production contracts for the remaining two plants.
        At December 31, 2012, Gallagher's tax-effected carrying value of these
        two investments was $0.8 million.  Gallagher cannot predict when these
        two plants will resume production of refined coal or the amount of
        refined coal that will ultimately be produced.
    --  2011 Era Plants - Seven of the fifteen plants are under long-term
        production contracts.  Gallagher's tax-effected carrying value of these
        investments at December 31, 2012 was $13.5 million and collectively they
        could generate approximately $12.0 million of net after-tax earnings per
        quarter through 2021.  Gallagher has signed long-term production
        agreements for two plants that may resume production in mid-2013. 
        Gallagher's tax-effected carrying value of these investments at December
        31, 2012 was $0.8 million and they could generate approximately $3.0
        million of net after-tax earnings per quarter through 2021 once
        production resumes.  Gallagher is in negotiations for long-term
        production agreements for two plants that may resume production in
        mid-2013.  Gallagher's tax-effected carrying value of these two
        investments at December 31, 2012 was $0.7 million and collectively they
        could generate approximately $1.5 million of net after-tax earnings per
        quarter through 2021 once production resumes.  Gallagher has been
        selected as a finalist in a request for proposal to provide refined coal
        at two of the remaining four plants, which had a tax-effected carrying
        value of $0.8 million at December 31, 2012.  Gallagher is seeking
        long-term production contracts for the remaining two plants which had a
        tax-effected carrying value of $0.8 million at December 31, 2012. 
        Gallagher cannot predict when these four plants will resume production
        of refined coal or the amount of refined coal that will ultimately be
        produced.
    --  For those 2009 and 2011 Era Plants that are not yet under long-term
        production contracts, we estimate that we will invest an average of $4.0
        million additional per plant on a tax-effected basis to connect and
        house each of these plants.  For those plants that will have majority
        ownership co-investors, the tax-effected average additional investment
        will be $2.0 million.
    --  Gallagher has sold co-investor majority ownership interests in twelve
        plants.  Gallagher also has agreements in principle with co-investors
        for the sale of majority ownership interests in five additional plants. 
        We may sell ownership interests in some or all of the remaining plants
        to co-investors.
    --  Gallagher's investment in Chem-Mod generates royalty income from clean
        energy plants owned by those limited liability companies in which it
        invests as well as clean energy plants owned by other unrelated parties.
        Based on current production estimates provided by licensees, Chem-Mod
        could generate for Gallagher approximately $3.6 million of net after-tax
        earnings per quarter.
    --  Please note that all estimates set forth above regarding the potential
        future quarterly earnings impact of our clean energy investments are
        subject to significant risks, including those referred to below under
        "Information Regarding Forward-Looking Statements."

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 as if those segments were computing income tax provisions on a separate company basis. Gallagher historically has reported, and anticipates reporting for the foreseeable future, an effective tax rate of approximately 37% to 39% in both its Brokerage and Risk Management segments. Gallagher's consolidated effective tax rate for the quarter ended December 31, 2012 and 2011 was 26.2% and 14.6%, respectively. Gallagher's tax rate for fourth quarter 2012 was lower than the statutory rate primarily due to the amount of IRC Section 45 tax credits earned in the quarter. Gallagher's effective tax rate for fourth quarter 2012 was higher than the same period in 2011 primarily due to several tax related adjustments made during fourth quarter 2011 which did not recur in 2012.

Any forward-looking statement made by Gallagher in this press release speaks only as of the date on which it is made. Except as required by applicable law, Gallagher does not undertake to update the information included herein or the corresponding earnings release posted on Gallagher's website.

Information Regarding Non-GAAP Measures

In addition to reporting financial results in accordance with GAAP, this press release provides information regarding EBITDAC, EBITDAC margin, adjusted EBITDAC, adjusted EBITDAC margin, diluted net earnings per share (as adjusted) for the Brokerage and Risk Management segments, adjusted revenues, adjusted compensation and operating expenses, adjusted compensation expense ratio, adjusted operating expense ratio and organic revenue measures for each operating segment. These measures are not in accordance with, or an alternative to, the GAAP information provided in this press release. Gallagher's management believes that these presentations provide useful information to management, analysts and investors regarding financial and business trends relating to Gallagher's results of operations and financial condition. Gallagher's industry peers may provide similar supplemental non-GAAP information related to organic revenues and EBITDAC, although they may not use the same or comparable terminology and may not make identical adjustments. The non-GAAP information provided by Gallagher should be used in addition to, but not as a substitute for, the GAAP information provided. 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.

(7 of 12)

Adjusted presentation - Gallagher believes that the adjusted presentations of the 2012 and 2011 information, presented in this earnings release, provides 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.


    --  Adjusted revenues and expenses - Gallagher defines these measures as
        revenues, compensation expense and operating expense, respectively, each
        adjusted to exclude gains realized from sales of books of business,
        Heath Lambert integration costs, New Zealand earthquake claims
        administration, South Australia ramp up costs, workforce related
        charges, lease termination related charges, acquisition related
        adjustments, the impact of foreign currency translation and effective
        income tax rate impact, as applicable.  Acquisition related adjustments
        include costs related to transactions 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.
    --  Adjusted ratios - Adjusted compensation expense ratio and adjusted
        operating expense ratio are defined as adjusted compensation expense and
        adjusted operating expense, respectively, further adjusted to exclude
        GAB Robins integration costs and South Australia ramp up costs, as
        applicable, each divided by adjusted revenues.

Earnings Measures - Gallagher believes that each of EBITDAC, EBITDAC margin, adjusted EBITDAC, adjusted EBITDAC margin and diluted net earnings per share (as adjusted) for the Brokerage and Risk Management segments, as defined below, provides a meaningful representation of its operating performance. Gallagher considers EBITDAC and EBITDAC margin as a way to measure financial performance on an ongoing basis. Adjusted EBITDAC, adjusted EBITDAC margin and diluted net earnings per share (as adjusted) for the Brokerage and Risk Management segments are presented to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability.


    --  EBITDAC - Gallagher defines this measure as net earnings before
        interest, income taxes, depreciation, amortization and the change in
        estimated acquisition earnout payables.
    --  EBITDAC margin - Gallagher defines this measure as EBITDAC divided by
        total revenues.
    --  Adjusted EBITDAC - Gallagher defines this measure as EBITDAC adjusted to
        exclude gains realized from sales of books of business, Heath Lambert
        integration costs, earnout related compensation charges, workforce
        related charges, lease termination related charges, New Zealand
        earthquake claims administration costs, GAB Robins integration costs,
        South Australia ramp up costs, acquisition related adjustments and the
        impact of foreign currency translation, as applicable.
    --  Adjusted EBITDAC margin - Gallagher defines this measure as adjusted
        EBITDAC divided by total adjusted revenues (defined above).
    --  Diluted net earnings per share (as adjusted) for the Brokerage and Risk
        Management segments - Gallagher defines this measure as net earnings
        adjusted to exclude the after-tax impact of gains realized from sales of
        books of business, Heath Lambert integration costs, New Zealand
        earthquake claims administration, GAB Robins integration costs, South
        Australia ramp up costs, the impact of foreign currency translation,
        workforce related charges, lease termination related charges,
        acquisition related adjustments, adjustments to change in estimated
        acquisition earnout payables and effective income tax rate impact
        divided by diluted weighted average shares outstanding.  The effective
        income tax rate impact represents the difference in income tax expense
        for tax amounts derived using the actual effective tax rate compared to
        tax amounts derived using a normalized effective tax rate.

Organic Revenues - Organic change in base commission and fee revenues excludes the first twelve months of net commission and fee revenues generated from acquisitions accounted for as purchases 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 organic growth excludes the impact of supplemental commission and contingent commission revenues, the period-over-period impact of foreign currency translation. The amounts excluded with respect to foreign currency translation are calculated by applying 2012 foreign exchange rates to the same periods in 2011. For the Risk Management segment, organic change in base domestic and international fee revenues excludes international performance bonus fees and New Zealand earthquake claims administration to improve the comparability of our results between periods by eliminating the impact of the items that have a high degree of variability or due to the limited-time nature of these revenue sources.

(8 of 12)

These revenue items are excluded from organic revenues in order to determine a comparable measurement of revenue growth that is associated with the revenue sources that will be continuing in 2013 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 measure allows financial statement users 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 page 10), for adjusted revenues, adjusted EBITDAC and adjusted diluted net earnings per share (on page 2), for organic revenue measures (on pages 3 and 4, respectively, for the Brokerage and Risk Management segments), for adjusted compensation and operating expenses and adjusted EBITDAC margin (on pages 3, 4 and 5, respectively, for the Brokerage and Risk Management segments). Reported compensation and operating expense ratios can be found in the supplemental quarterly data available at www.ajg.com.

    Notes to Fourth Quarter 2012 Earnings Release

                                           (1)   Reported supplemental commission revenues recognized in 2012, 2011 and 2010 by quarter are shown in the
                                                 financial supplement.  As previously disclosed, many insurance carriers now provide sufficient
                                                 information for Gallagher to recognize supplemental commission revenues on a quarterly basis for a
                                                 majority of its 2012, 2011 and 2010 supplemental commission arrangements. However, in 2009 and prior
                                                 years, most carriers only provided this information on an annual basis after the end of the contract
                                                 period. Accordingly, the 2010 amounts reported in the table include both a full year of 2009
                                                 supplemental commission revenues and 2010 supplemental commission revenues that were recognized by
                                                 Gallagher on a quarterly basis. This situation did not occur again in 2011 or 2012 and should not occur
                                                 in 2013 or later years as Gallagher anticipates that most of the carriers will continue to provide
                                                 information on a quarterly basis sufficient to allow recognition of revenues in a similar manner in
                                                 future quarters. The reported and adjusted supplemental commissions for 2012, 2011 and 2010 are as
