ADP Reports Second Quarter Fiscal 2009 Results; Second Quarter Revenues Grow 2.5%; EPS From Continuing Operations Increases 7%, or 11% Excluding $0.02 Per Share Benefit From a Favorable Tax Settlement in Last Year's Second Quarter; Confirms Fiscal 2009 Revenue and EPS Growth Forecasts

ROSELAND, N.J., Feb. 3, 2009 (GLOBE NEWSWIRE) -- Automatic Data Processing, Inc. (Nasdaq:ADP) reported 2.5% revenue growth to $2.20 billion for the second fiscal quarter ended December 31, 2008, Gary C. Butler, president and chief executive officer, announced today. Revenue growth was negatively impacted nearly 3 percentage points by unfavorable foreign exchange rates during the quarter. Pretax earnings from continuing operations grew 7%. Net earnings from continuing operations grew 3% and diluted earnings per share from continuing operations increased 7% to $0.59 from $0.55 a year ago on fewer shares outstanding. The prior fiscal year's second quarter included a favorable settlement of a state tax matter which reduced our provision for income taxes by $12.4 million. This tax benefit reduced the prior fiscal year's second quarter effective tax rate nearly 3 percentage points to 33.8% and contributed approximately $0.02 to earnings per share to the quarter ended December 31, 2007. Excluding the prior year's favorable tax settlement, fiscal 2009 net earnings and diluted earnings per share from continuing operations increased 8% and 11%, respectively.

Fiscal year-to-date, ADP acquired 11.1 million shares of its stock for treasury at a cost of over $450 million. Cash and marketable securities at December 31, 2008 were $1.45 billion.

Commenting on the results, Mr. Butler said, "Despite economic headwinds, I am pleased that ADP continues to grow. As anticipated, ADP's second quarter revenue growth was negatively impacted by a stronger U.S. dollar compared to last year's second quarter. Additionally, the weakened selling environment in Employer Services and PEO Services continued due to market uncertainty about the length and depth of the U.S. recession. Our same-store-sales employment metric turned negative during the quarter, reflecting rising U.S. unemployment levels. Dealer Services' results continue to reflect the state of the North American automobile market, posting a 1% decline in revenues for the quarter. In spite of these challenges, we continue to make investments that will drive our strategic growth program while appropriately controlling spending."

Employer Services

"Employer Services' revenues increased 6% in the second quarter compared with the same period last year. In the United States, revenues from our payroll and payroll tax filing business grew 3%, and beyond payroll revenues grew 10%. The number of employees on our clients' payrolls in the United States decreased 0.6%, as measured on a same-store-sales basis for clients on our AutoPay platform. Worldwide client retention continued at excellent levels, although declining 0.5 percentage points fiscal year to date through December 31, 2008 compared with the same period last year. Retention continued to be negatively impacted by price sensitivity and an increased level of out of businesses as a result of the weak economy. The dollar value of new business sold worldwide during the quarter in Employer Services and PEO Services was 13% less than the prior year's second quarter reflecting continued economic uncertainty in the market. The dollar value of new business sold during the quarter represents the expected new annual recurring revenue dollars to be generated from each sale. Employer Services' pretax margin improved 160 basis points due to operating leverage, continued expense controls, and lower selling expenses from lower new business sales."

PEO Services

"PEO Services' revenues increased 14% in the second quarter compared with the same period last year. PEO Services' pretax margin was flat compared to the year ago period as a result of higher benefits pass through costs. Average worksite employees paid by PEO Services increased over 22,000 to approximately 193,000, or 13%, compared with the second quarter of fiscal 2008."

Dealer Services

"Dealer Services' revenues declined 1% in the second quarter compared with the same period last year. Pretax margin expanded 30 basis points. Ongoing difficulties in the North American auto markets have resulted in continued dealership consolidations and closings, with remaining dealers under pressure to reduce costs. While sales are lower compared with a year ago, I am pleased with our continued win rate versus the competition, which has enabled us to gain market share in a consolidating North American marketplace."

Interest on Funds Held for Clients and Interest Expense

"Safety and liquidity of our clients' funds are the foremost objectives of our investment strategy. Client funds are invested in accordance with ADP's prudent and conservative investment guidelines and the overall credit quality of the investment portfolio is AAA/AA."

"For the second fiscal quarter, interest on funds held for clients of $147.3 million declined $14.7 million, or 9.1%, due to a decline of 30 basis points in the average interest yield to 4.2%, and a decline of 1.2% in average client funds balances to $14.1 billion."

"Interest expense of $8.1 million for the second quarter declined $22.6 million, or 73.6% compared with the same period last year. The decline in interest expense was primarily the result of a 390 basis point decline in our average commercial paper borrowing rate to 0.7%, partially offset by higher average daily commercial paper borrowings which increased $0.3 billion to $2.5 billion. We utilize our short-term financing arrangements to satisfy our short-term funding requirements related to client funds obligations in order to extend the maturities of our investment portfolio, thus averaging our way through an interest rate cycle."

Fiscal 2009 forecast

"As we enter into the second half of fiscal 2009, we continue to face headwinds from a difficult economic environment. The strength of our business model with highly recurring revenues, strong client retention, the laddered investment strategy for our client funds portfolio, and execution against our cost containment measures, enable us to maintain our fiscal 2009 forecasts in this challenging period. We continue to anticipate 2% to 3% revenue growth, and 10% to 14% growth in diluted earnings per share from continuing operations, up from $2.18 in fiscal 2008 (which excludes the net one-time gain of $0.02 per share recorded in the fourth quarter of fiscal 2008). Our revenue growth forecast for the year is negatively impacted about two percentage points due to our assumption of unfavorable foreign exchange rates continuing for the remainder of the fiscal year."

"For Employer Services, we continue to anticipate revenue growth of about 5%, and currently anticipate about 100 basis points of pretax margin expansion. We anticipate 14% to 15% revenue growth for PEO Services, and up to 50 basis points of pretax margin expansion. Despite the difficult selling environment, we are still on track to deliver over $1 billion worldwide in new business sales for Employer Services and PEO Services on a combined basis, which represents a decline of about 10% from about $1.15 billion in new business sales last fiscal year. For Dealer Services, we anticipate revenues will be flat to slightly down, and a flat pretax margin compared with a year ago. This updated forecast reflects the considerable challenges facing the automotive industry, and includes Dealer Services' recently announced acquisition of Automaster Oy, a DMS provider based in Finland, with established footprints in many markets, including the Nordic region, Central and Eastern Europe, and Russia."

"We have also updated our client funds portfolio forecast. The interest assumptions in our current forecast assume overnight funds will yield nearly 0.5% on average for the remainder of the fiscal year. The three-and-a-half and five-year U.S. government agency rates based on the forward yield curves as of January 26, 2009 were used to forecast new purchase rates for the extended and client long portfolios, respectively."

"Interest on funds held for clients is expected to decline $75 to $80 million, or 11% to 12%, from $684.5 million in fiscal 2008 based on an approximate 40 basis point decline in the expected average interest yield to about 4.0%, and an anticipated decline of 1% to 2% in average client funds balances. This updated forecast includes an unfavorable Canadian foreign exchange rate which is expected to negatively impact our full-year average client funds balance forecast by 1.5 percentage points. The forecasted interest on funds held for clients is $10 to $20 million lower than our previous estimate primarily due to the expected lower average client funds balances as a result of lower forecasted wage growth, including lower bonuses, and an increased negative impact expected from the Canadian foreign exchange rate."

"Interest expense is expected to decline about $50 million from $80.5 million in fiscal 2008, primarily from lower interest expense on our short-term financing related to our client funds extended investment strategy due to an expected decline of approximately 320 basis points in average commercial paper borrowing rates, partially offset by an expected increase of about $0.4 billion in average daily commercial paper borrowings to about $1.9 billion. This interest expense forecast is $10 to $15 million favorable to our previous estimate primarily due to expected lower borrowing costs."

"The changes in the interest on funds held for clients and interest expense forecasts result in an estimated net $5 million reduction to pretax earnings, or less than $0.01 per share."

"There are numerous challenges facing businesses today. Economic indicators are weak, and no one is immune to the pressures of a recession. However, I am pleased that ADP continues to grow and navigate successfully through this uncertain economic environment. ADP is a leader in its industry and I continue to believe that ADP's long-term opportunities for growth are strong," Mr. Butler concluded.
