ADP REPORTS SECOND QUARTER FISCAL 2008 RESULTS;

CONFIRMS FISCAL 2008 REVENUE AND

EPS FROM CONTINUING OPERATIONS GROWTH FORECASTS

Second Quarter Revenues Grow Nearly 15%;

 EPS from Continuing Operations Increases 22% to $0.55 including $0.02 from Tax Benefits

ROSELAND, New Jersey, February 1, 2008 - Automatic Data Processing, Inc. (NYSE:ADP) announced nearly 15% revenue growth to $2.15 billion, with over 12% growth on a constant foreign currency basis, for the second fiscal quarter ended December 31, 2007, Gary C. Butler, president and chief executive officer, announced today.  Pretax earnings from continuing operations grew 11% compared with last year’s second quarter.  During the second quarter of fiscal 2008 the company recorded a reduction in the provision for income taxes of $12.4 million, which was primarily related to the settlement of a state tax matter.  This tax benefit reduced the quarter’s effective tax rate nearly 3 percentage points to 33.8%, and contributed 5 percentage points of the 18% growth in net earnings from continuing operations and approximately $0.02 of earnings per share.  Diluted earnings per share from continuing operations increased 22% to $0.55 from $0.45 a year ago on fewer shares outstanding.

Fiscal year to date, ADP acquired over 18 million shares of its stock for treasury at a cost of nearly $842 million.  At December 31, 2007, cash and marketable securities balances were $1.4 billion.

Commenting on the results, Mr. Butler said, “We are pleased with our results for the second quarter.  Our continued strong performance confirms the strength of our recurring revenue business model.”

Employer Services

“Employer Services had a strong quarter.  Revenues increased 11% for the second quarter.  Organic revenue growth was nearly 10%, up from nearly 9% a year ago.  In the United States, revenues from our traditional payroll and payroll tax filing business grew over 8%.  Our beyond payroll revenues in the United States, excluding PEO Services revenues, grew 16%.  The number of employees on our clients' payrolls in the United States increased 1.7%, and pay growth in Europe was stronger than it has been in several years.  As we headed into the key client retention period at the start of the calendar year, worldwide client retention, while slightly lower than last year’s second quarter, remained at excellent levels.  Employer Services’ pretax margin improved nearly 70 basis points as a result of operating leverage.”

“Combined new business sales growth for Employer Services and PEO Services was over 8% worldwide.  New business sales represent annualized recurring revenues anticipated from new orders.”

PEO Services

“PEO Services’ revenues increased 22% for the second quarter, all organic.  PEO Services’ pretax margin declined 20 basis points.  Average worksite employees paid by PEO Services increased to approximately 170,000, or 20%, compared with the second quarter of fiscal 2007.”

Dealer Services

“Dealer Services’ results were also strong for the quarter.  Revenues increased 9.5% for the second quarter.   Organic revenue growth continued to improve with 7% growth in the quarter compared with 5% growth a year ago.  New business sales growth was very strong in both our North American and International businesses.  Operating leverage, partially offset by the dilutive effect of fiscal 2008 first quarter acquisitions, drove nearly 90 basis points of improvement in Dealer Services’ pretax margin.”

Client Funds

"Interest on funds held for clients grew approximately 14% over last year's second quarter, to $162.0 million, due to an 8.9% increase in average client funds balances to $14.3 billion and a higher average interest yield of 20 basis points to 4.5% from an average interest yield of 4.3% last year.  This 20 basis point increase in average interest yield is due to our investment strategy of laddering maturities on marketable securities.”

Fiscal 2008 forecast

“We anticipate continued strong growth in our businesses, and are affirming our forecast of 12% to 13% revenue growth for fiscal 2008.  This forecast includes our current estimate of one to two percentage points of anticipated benefit from foreign exchange rates.”

“We move into the second half of fiscal 2008 facing headwinds from lower interest rates and economic uncertainty.  However, we remain confident in our ability to achieve the high-end of our 18% to 21% forecasted growth in diluted earnings per share from continuing operations, up from $1.80 in fiscal 2007 which excludes the net one-time gain recorded in the first quarter of fiscal 2007.  This forecast includes the following items which were not reflected in our previous forecast on October 30, 2007:

•   $0.02 from the reduction in the income tax provision in the second quarter primarily from a state tax settlement;

•   About $0.01 additional accretion from share repurchases subsequent to the first quarter;  and

•   $0.01 from the current estimated benefit of favorable foreign exchange rates anticipated for the fiscal year.

This approximate $0.04 anticipated increase in earnings per share is partially offset by:

•   ($0.03) from lower expected client funds interest revenues based on Fed Funds futures contracts and forward yield curves as of January 31, 2008 as well as lower anticipated client funds balance growth.”

“For Employer Services, we anticipate revenue growth of approximately 10%, which is slightly lower than our previous forecast partially due to lower forecasted growth in client funds balances.  We are slightly narrowing our anticipated pretax margin expansion to 70 to 110 basis points.  For PEO Services, we continue to anticipate 19% to 20% revenue growth and pretax margin expansion of 50 to 90 basis points.  We continue to forecast high single-digit to low double-digit new business sales growth worldwide for Employer Services and PEO Services on a combined basis.  We continue to anticipate revenue growth of about 10% in Dealer Services, and pretax margin expansion of 70 to 90 basis points.”

“Included in our guidance is an update of our client funds portfolio forecasts. The interest assumptions in our current forecasts are based on Fed Funds futures contracts and forward yield curves as of January 31, 2008.  The Fed Funds futures contracts anticipate two further declines of 25 basis points each when the Fed is scheduled to meet in March and April 2008, exiting the fiscal year with a Fed Funds rate of 2.50%.  The forward yield curves as of January 31, 2008 indicate a decline in fixed income rates of over 100 basis points since our last guidance update on October 30, 2007.  Interest on funds held for clients is now anticipated to grow 3% to 4% based on expected growth of about 7% in average client funds balances and a full-year average interest yield of over 4.3%, compared with the fiscal 2007 average interest yield of nearly 4.5%.  This forecast is about $25 million lower than our previous estimate of about 8% growth in interest on funds held for clients, which was based on expected growth of 7% to 8% in average client funds balances and an overall yield of nearly 4.5%.”

“We are in a softening economic environment.  However, I remain pleased with ADP’s strong performance during the first half of fiscal 2008, and we are on target to deliver strong forecasted results for the year.  We are the global market leader and have a strong portfolio of products and services.  We intend to continue our investments in new products, salesforce expansion, and implementation and client service resources while sustaining our discipline around pretax margin expansion.  We remain keenly focused on our five-point strategic growth program and remain confident in our ability to continue to deliver both strong revenue growth and margin improvement over our strategic planning horizon.” Mr. Butler concluded.
