This earnings release contains certain non-GAAP information. EBITDA, a non-GAAP measure, represents earnings before interest, income taxes, depreciation, amortization and change in estimated acquisition earnout payables. A reconciliation of EBITDA to earnings from continuing operations before income taxes (which were $74.1 million and $69.3 million in second quarter 2009 and 2008, respectively, and $117.6 million and $96.2 million in the six-month periods ended June 30, 2009 and 2008, respectively) is included on page 5 of this earnings release.

“I am pleased with our second quarter results given we are still operating in an extremely difficult environment. Insurance rates were still soft in the second quarter, the economy continues to adversely impact our clients’ buying activities and investment yields are at all time lows,” said J. Patrick Gallagher Jr., Chairman, President and CEO. “Despite these headwinds, we continue to see the benefits of our tuck-in acquisition strategy and cost savings initiatives in our expanding EBITDA margins. Even with a 0.3% decline in organic revenue in second quarter 2009 in our combined Brokerage and Risk Management Segments, we expanded the combined EBITDA margin 0.9% compared to the same period in 2008.

“For the first six months of 2009, our Brokerage and Risk Management operations combined to grow revenues 7%, grow EPS 15%, grow EBITDA 24% and expand EBITDA margins by 2.9% from the same period in 2008. I’m proud of how all Gallagher associates are pulling together in these difficult times to deliver outstanding service to our clients and continue to build shareholder value.”

Brokerage Segment Second Quarter Highlights

• On July 23 and July 27, 2009, respectively, Gallagher amended its settlement agreements with the Illinois Attorney General and the Illinois Department of Insurance. The amendments, which will be effective as of October 1, 2009, will permit Gallagher to accept retail contingent commissions across all lines of its brokerage business. As a result, Gallagher anticipates generating additional retail contingent commission revenues of approximately $10.0 million on an annualized basis by 2011.

• Revenue growth of 9%. Organic revenue declined 1.2% compared to 2008. Included in organic revenue was an increase in supplemental commissions in 2009 over 2008, of $2.5 million. Items excluded from organic growth computations yet impacting second quarter 2009 to 2008 revenue comparisons include (in millions):

		2009			2008
Total revenues as reported		$	340.1		$	312.2
Less adjustments to revenues:
Gains realized from books of business sales			3.3			3.5
Investment income			1.4			4.3
Retail contingent commissions related to acquisitions			4.4			3.3
MGA/MGU performance income			1.9			1.7
Revenues from acquisitions in the last twelve months			41.6			—
Revenues related to divestitures in the last twelve months			—			3.3
Levelized foreign currency			—			5.0
Total revenue adjustments			52.6			21.1
Organic revenues		$	287.5		$	291.1

• Second quarter compensation expense ratio was 2.4% higher than 2008 as the result of increased headcount from the Liberty-Wausau transaction of 0.5%, increased pension expense of 0.6%, increased medical benefits of 0.6%, increased incentive compensation of 0.6% and severance costs of 0.2%.

• Second quarter operating expense ratio was 2.9% lower than 2008. The ratio was primarily impacted by lower travel and meeting expenses of 1.4%, decreased professional fees of 0.6% and foreign currency translation of 0.5%.

• The change in estimated acquisition earnout payables expense relates to the adoption of Statement of Financial Accounting Standards No. 141 (SFAS 141(R)), which was effective January 1, 2009 for acquisitions completed in 2009.

• EBITDA margin of 26.3%, which was up 0.6% as compared to 2008.

• Second quarter effective tax rate was 40.3% in 2009 and 40.2% in 2008.

• Gallagher shifted and diversified nearly all of its world-wide cash balances into accounts that were insured/guaranteed by various governments or governmental agencies. Most of these accounts are non-interest bearing. While Gallagher believes that these accounts are secure, there can be no assurances that governmental guarantee programs would be sufficient to repay balances in the event of a system-wide failure of the global banking system.

Risk Management Segment Second Quarter Highlights

• Revenue declined 2%. Organic growth was 2.2% after excluding the impact of foreign currency translation of $3.5 million. Domestic revenues declined 1%, reflecting reduced claim counts. International revenues grew 1% and after excluding the impact of foreign currency translation, revenue increased 25% reflecting new business and renewal increases. International revenues in the quarter also included a $2.3 million performance bonus compared to zero for the same period in 2008.

• Second quarter compensation expense ratio was 0.6% higher than 2008 as a result of increased pension expense of 0.6% and increased medical benefits of 0.5%, partially offset by reduced temporary help.

• Second quarter operating expense ratio was 1.5% lower than 2008 reflecting savings in travel and meeting expense of 1.5%, savings in office expenses of 0.9% and lower rent expense of 0.4%, partially offset by higher business insurance costs of 1.5%.

• EBITDA margin of 14.5%, which was up 0.9% compared to 2008.

• Second quarter effective tax rate was 41.0% in 2009 and 39.3% in 2008.

Financial Services and Corporate Segment Second Quarter Highlights

• Gallagher owns 42% of Chem-Mod, LLC which has developed technologies that reduce harmful emissions from coal-fired power plants. Gallagher believes that commercial facilities, which produce clean-burning coal using the Chem-Mod technology, may qualify for tax credits under Internal Revenue Code Section 45 provided the facilities are placed in service by December 31, 2009. Certain utilities have expressed an interest in using Chem-Mod’s technologies and Gallagher has committed to capital expenditures of approximately $4.0 million in third quarter 2009 to build the first facility. If other utilities express interest in using the Chem-Mod technology, Gallagher is prepared to make additional capital expenditures of $10.0 to $12.0 million in third and fourth quarters of 2009 to build additional facilities. There are significant uncertainties related to these investments, which must be favorably resolved in order for Gallagher to capitalize on these investments, including the release of favorable IRS guidance, the timely receipt by the utility of regulatory permits and completion of construction by December 31, 2009. Accordingly, it is too early to forecast the value, if any, of these facilities or Gallagher’s ownership interest in Chem-Mod.

• In addition to the $400.0 million of long-term borrowing outstanding under the Note Purchase Agreement, at June 30, 2009, Gallagher had borrowings of $193.0 million outstanding under its line of credit facility used primarily to fund 2008 and 2009 acquisitions and short-term cash flow needs. The weighted average interest rate on the line of credit borrowings, which is based on a spread over short-term LIBOR, was 0.92%. The interest rate at July 24, 2009 for a sixty day borrowing on this line was 0.95%.

Consolidated Company Income Taxes

Gallagher allocates the provision for income taxes to the Brokerage and Risk Management Segments as if those segments were preparing income tax provisions on a separate company basis. Gallagher historically reported, and anticipates reporting for the foreseeable future, an effective tax rate of approximately 40% to 42% in both its Brokerage and Risk Management Segments. Gallagher’s consolidated effective tax rate for second quarter was 40.9% in 2009 and 39.8% in 2008. The second quarter tax rate in 2009 was higher than 2008 as the result of resolving certain income tax matters in second quarter 2008.

The company will host a webcast conference call on Wednesday, July 29, 2009 at 9:00 a.m. ET to further discuss these quarterly results. To listen, please go to www.ajg.com.
