	•		Total revenue was $500.2 million.
	•		Operating income decreased 14% to $189.9 million, as interest on funds held for clients decreased 43%.
	•		Operating income excluding interest on funds held for clients decreased 11% to $176.2 million.
	•		Net income and diluted earnings per share decreased 17% to $123.6 million and $0.34 per share, respectively.

     ROCHESTER, NY, September 23, 2009 — Paychex, Inc. (“we,” “our,” or “us”) (NASDAQ:PAYX) today announced total revenue of $500.2 million for the three months ended August 31, 2009 (the “first quarter”), a decrease of 6% from $534.1 million for the same period last year. Net income and diluted earnings per share decreased 17% to $123.6 million and $0.34 per share, respectively.

     “The weak economic conditions, credit crisis in the financial markets, and extremely low investment rates of return that we experienced during fiscal 2009 continue to challenge our financial results for fiscal 2010. While we have not seen improvement in any of our key indicators, we have not seen any significant deterioration either. On a positive note, this is the first quarter in the last four sequential quarters that we have not had a noticeable decline in checks per client. The largest sequential decline in fiscal 2009 peaked in the third quarter at 2.2%,” commented Jonathan J. Judge, President and Chief Executive Officer of Paychex.

     “We have remained steadfast in providing excellent customer service and investing in our business, while continuing to control expenses. Our financial position remains strong with significant cash and total corporate investments and no debt as of August 31, 2009,” added Mr. Judge.

     Payroll service revenue decreased 6% to $354.4 million for the first quarter from the same period last year. Weak economic conditions negatively impacted our client growth, check volume, and revenue per check. Our checks per client decreased 5.0% for the first quarter compared to the same period last year. Our client base growth has been adversely impacted by weak new business starts and continued client losses from companies going out of business.

     Human Resource Services revenue increased 1% to $132.1 million for the first quarter from the same period last year. Contributing to Human Resource Services revenue growth in the quarter, as compared to the same quarter last year are: an increase of 4% for comprehensive human resource outsourcing services client employees served to 463,000; an increase of 10% for comprehensive human resource outsourcing services clients to 18,000; and an increase of 5% for workers’ compensation insurance clients to 78,000 as of August 31, 2009. In addition, health and benefits services revenue grew 39% in the first quarter compared to the same period last year.

     The asset value of retirement services client employees’ funds increased 2% year-over-year to $9.6 billion as of August 31, 2009 (up 34% compared to our lowest fiscal 2009 asset value of $7.2 billion as of February 28, 2009), due to retirement plans converting with existing assets. However, the shift in the mix of assets in the retirement services client employees’ funds to investments earning lower fees from external fund managers has generated lower revenue than the same quarter last year. The impact from weak economic conditions on our payroll client base has nearly offset our revenue growth from Human Resource Services, as these ancillary services are most often provided to our payroll clients. The most significant impacts have been to retirement services and comprehensive human resource outsourcing services revenue.

     Total expenses decreased 1% to $310.3 million for the first quarter compared to the same period last year. This decline is primarily due to overall cost control measures and stable headcount, offset slightly by costs related to continued investment in key areas of our sales force and our technological infrastructure.

     For the first quarter, our operating income was $189.9 million, a decrease of 14% from the same period last year. Operating income excluding interest on funds held for clients (see Note 1 on page 3 for further description) decreased 11% to $176.2 million for the first quarter as compared to $197.4 million for the same period last year.

		For the three months ended
		August 31,
$ in millions		2009				2008				% Change
Operating income		$	189.9			$	221.6				(14	%)
Excluding interest on funds held for clients			(13.7	)			(24.2	)			(43	%)
Operating income excluding interest on funds held for clients		$	176.2			$	197.4				(11	%)

     We continue to follow our investment strategy of maximizing liquidity and protecting principal. With the turmoil in the financial markets, this translates to significantly lower yields on high quality instruments, impacting our income earned on funds held for clients and corporate investments. We are seeing gradual improvements in liquidity for high quality money market securities and are beginning to explore opportunities to invest a portion of the short-term portfolio in investments other than United States (“U.S.”) agency discount notes.

     For the first quarter, interest on funds held for clients decreased 43% to $13.7 million due to lower average interest rates earned and lower average investment balances. Average investment balances for funds held for clients decreased 10% for the first quarter compared to the prior year period. This decline was a result of overall economic factors, which have negatively impacted our client base, and the impact of the American Recovery and Reinvestment Act of 2009 (the “2009 economic stimulus package”) generating lower tax withholdings for client employees. Investment income decreased 70% to $0.9 million, primarily due to lower average interest rates earned, offset by higher average investment balances resulting from investment of cash generated from operations.

     Average investment balances and interest rates are summarized below:

		For the three months ended
		August 31,
$ in millions		2009				2008
Average investment balances:
Funds held for clients		$	2,907.2			$	3,220.1
Corporate investments		$	618.4			$	484.5
Average interest rates earned (exclusive of net realized gains):
Funds held for clients			1.8	%			3.0	%
Corporate investments			0.7	%			2.6	%
Net realized gains:
Funds held for clients		$	0.3			$	0.3
Corporate investments		$	—			$	—

     Our exposure has been limited in the current investment environment as the result of our policies of investing in primarily high credit quality securities with AAA and AA ratings and short-term securities with A-1/P-1 ratings, and by limiting the amounts that can be invested in any single issuer. All the investments we held as of August 31, 2009 are traded in active markets. In the current investment market, our primary short-term investment vehicle is U.S. agency discount notes. We have not and do not utilize derivative financial instruments to manage interest rate risk.

     The available-for-sale securities within the funds held for clients and corporate investment portfolios reflected a net unrealized gain of $68.6 million as of August 31, 2009, compared with a net unrealized gain of $66.7 million as of May 31, 2009. During the first quarter of fiscal 2010, the net unrealized gain on our investment portfolios ranged from $55.1 million to $76.7 million. The net unrealized gain on our investment portfolios was approximately $74.8 million as of September 18, 2009.

OUTLOOK

     Our outlook for the fiscal year ending May 31, 2010 (“fiscal 2010”) reflects the impact of current economic and financial conditions, and assumes these conditions will continue through the remainder of the fiscal year. Consistent with our policy regarding guidance, our projections do not anticipate or speculate on future changes to interest rates. Comparisons to the prior year are expected to improve in the second half of fiscal 2010.

     Projected changes in revenue and net income for fiscal 2010 are as follows:

		Low				High
Payroll service revenue			(7	%)	—	(5	%)
Human Resource Services revenue			3	%	—	6	%
Total service revenue			(5	%)	—	(2	%)
Interest on funds held for clients			(30	%)	—	(25	%)
Total revenue			(5	%)	—	(2	%)
Investment income, net			(35	%)	—	(30	%)
Net income			(12	%)	—	(10	%)

     Operating income excluding interest on funds held for clients as a percentage of service revenue is expected to range from 34% to 35% for fiscal 2010. The effective income tax rate is expected to approximate 35% throughout fiscal 2010. The higher tax rate in fiscal 2010 is driven by higher state income tax rates resulting from state legislative changes.

     Interest on funds held for clients and investment income for fiscal 2010 are expected to be impacted by interest rate volatility. Interest on funds held for clients will be further impacted by a projected 7% decline in average invested balances, with most of the effect in the first half of fiscal 2010. This decline is largely the result of the 2009 economic stimulus package generating lower tax withholdings for client employees.

     Based upon current interest rate and economic conditions, we expect interest on funds held for clients and investment income to (decrease)/increase by the following amounts in the remaining respective quarters of fiscal 2010:

		Interest on funds held				Investment income,
Fiscal 2010		for clients				net
Second quarter			(35	%)			(40	%)
Third quarter			(20	%)			10	%
Fourth quarter			(15	%)			50	%

Note 1: In addition to reporting operating income, a U.S. generally accepted accounting principle (“GAAP”) measure, we present operating income excluding interest on funds held for clients, which is a non-GAAP measure. We believe operating income excluding interest on funds held for clients is an appropriate additional measure, as it is an indicator of our core business operations performance period over period. It is also the measure used internally for establishing the following year’s targets and measuring management’s performance in connection with certain performance-based compensation payments and awards. Interest on funds held for clients is an adjustment to operating income due to the volatility of interest rates which are not within the control of management. Operating income excluding interest on funds held for clients is not calculated through the application of GAAP and is not the required form of disclosure by the Securities and Exchange Commission (“SEC”). As such, it should not be considered as a substitute for the GAAP measure of operating income and, therefore, should not be used in isolation, but in conjunction with the GAAP measure. The use of any non-GAAP measure may produce results that vary from the GAAP measure and may not be comparable to a similarly defined non-GAAP measure used by other companies.
