Administaff, Inc. (NYSE:ASF), a leading provider of human resources services for small and medium-sized businesses, today announced results for the fourth quarter and year ended December 31, 2008. The company reported fourth quarter net income of $9.7 million and diluted earnings per share of $0.39, down from $13.3 million and $0.50 in the 2007 quarter. For the full year, the company reported net income and diluted net earnings per share of $45.8 million and $1.79, compared to $47.5 million and $1.74 in 2007. Lower interest rates negatively impacted investment income, the discounting of workers’ compensation reserves, and the effective income tax rate by $0.06 per share in the fourth quarter and $0.19 per share for the full year 2008 when compared to the respective periods in 2007.

"We are very pleased with Administaff’s financial performance in 2008 against the backdrop of a deteriorating economic climate,” said Paul J. Sarvadi, Administaff chairman and chief executive officer. "While the growth of our sales staff is encouraging, we have taken a conservative approach to our 2009 operating plan given the recent weakness in the labor market and the near-term outlook for the economy.”

Fourth Quarter Results

Revenues for the fourth quarter of 2008 increased 5.9% over the 2007 period to $426.0 million, due to a 2.9% increase in the average number of worksite employees paid per month and a 3.0% increase in revenues per worksite employee per month.

Gross profit increased 3.8% over the fourth quarter of 2007 to $87.6 million, due to the growth in the average number of worksite employees paid and an increase in the average gross profit per worksite employee per month from $244 in the 2007 period to $246 in the 2008 period.

Operating expenses for the quarter increased 10.3% to $73.1 million, largely attributable to salaries and wages associated with sales staffing levels and increased marketing efforts.

Operating income for the fourth quarter of 2008 decreased 19.8% to $14.5 million, with an average operating income per worksite employee per month of $41 compared to $52 in the 2007 period.

EBITDA for the fourth quarter was $19.6 million. Cash outlays included share repurchases of $18.5 million, capital expenditures of $4.1 million and dividends of $3.3 million.

The statements contained herein that are not historical facts are forward-looking statements within the meaning of the federal securities laws (Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934). You can identify such forward-looking statements by the words "expects,” "intends,” "plans,” "projects,” "believes,” "estimates,” "likely,” "possibly,” "probably,” "goal,” "objective,” "target,” "assume,” "outlook,” "guidance,” "predicts,” "appears,” "indicator” and similar expressions. Forward-looking statements involve a number of risks and uncertainties. In the normal course of business, Administaff, Inc., in an effort to help keep our stockholders and the public informed about our operations, may from time to time issue such forward-looking statements, either orally or in writing. Generally, these statements relate to business plans or strategies, projected or anticipated benefits or other consequences of such plans or strategies, or projections involving anticipated revenues, earnings, unit growth, profit per worksite employee, pricing, operating expenses or other aspects of operating results. We base the forward-looking statements on our current expectations, estimates and projections. These statements are not guarantees of future performance and involve risks and uncertainties that we cannot predict. In addition, we have based many of these forward-looking statements on assumptions about future events that may prove to be inaccurate. Therefore, the actual results of the future events described in such forward-looking statements could differ materially from those stated in such forward-looking statements. Among the factors that could cause actual results to differ materially are: (i) changes in general economic conditions; (ii) regulatory and tax developments and possible adverse application of various federal, state and local regulations; (iii) changes in our direct costs and operating expenses including, but not limited to, increases in health insurance costs and workers’ compensation rates and underlying claims trends, financial solvency of workers’ compensation carriers and other insurers, state unemployment tax rates, liabilities for employee and client actions or payroll-related claims, changes in the costs of expanding into new markets, and failure to manage growth of our operations; (iv) the effectiveness of our sales and marketing efforts; (v) changes in the competitive environment in the PEO industry, including the entrance of new competitors and our ability to renew or replace client companies; and (vi) our liability for worksite employee payroll and benefits costs. These factors are discussed in further detail in Administaff’s filings with the U.S. Securities and Exchange Commission. Any of these factors, or a combination of such factors, could materially affect the results of our operations and whether forward-looking statements we make ultimately prove to be accurate.

Non-bonus payroll cost represents payroll cost excluding the impact of bonus payrolls paid to the company’s worksite employees. Bonus payroll cost varies from period to period, but has no direct impact to the company’s ultimate workers’ compensation costs under the current program. As a result, Administaff management refers to non-bonus payroll cost in analyzing, reporting and forecasting the company’s workers’ compensation costs.

EBITDA represents net income computed in accordance with generally accepted accounting principles ("GAAP”), plus interest expense, income tax expense, depreciation and amortization expense. Administaff management believes EBITDA is often a useful measure of the company’s operating performance, as it allows for additional analysis of the company’s operating results separate from the impact of taxes and capital and financing transactions on earnings.

Non-bonus payroll and EBITDA are not financial measures prepared in accordance with GAAP and may be different from similar measures used by other companies. Non-bonus payroll and EBITDA should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. Administaff includes non-bonus payroll and EBITDA in this press release because the company believes they are useful to investors in allowing for greater transparency related to the costs incurred under the company’s workers’ compensation program and the company’s operating performance during the periods presented. Investors are encouraged to review the reconciliation of the non-GAAP financial measures used in this press release to their most directly comparable GAAP financial measures as provided in the tables above.
