ADP Reports Fourth Quarter and Fiscal 2009 Results; Provides Fiscal 2010 Guidance

   For the Year, Revenues Rise 1% With EPS From Continuing Operations of
           $2.63 ($2.39 Excluding Certain Items, a 10% Increase)

  Forecasting Fiscal 2010 Revenues Down 1% to 4% With $2.29 to $2.39 EPS

ROSELAND, N.J., July 30, 2009 (GLOBE NEWSWIRE) -- Automatic Data Processing, Inc. (Nasdaq:ADP) reported 1% revenue growth to $8.9 billion for the fiscal year ended June 30, 2009, Gary C. Butler, president and chief executive officer, announced today. Revenue growth was negatively impacted by continued severe economic conditions and about 2 percentage points from unfavorable foreign exchange rates. As reported, pretax earnings from continuing operations grew 5%, net earnings from continuing operations grew 14%, and diluted earnings per share from continuing operations increased 20% to $2.63 from $2.20 a year ago on fewer shares outstanding. The fourth quarter of fiscal 2009 included tax benefits related to favorable settlements of income tax matters which reduced the provision for income taxes by $120.0 million. Last year's fourth quarter included a $16.0 million pretax gain on the sale of a building. Excluding the current year favorable tax settlements and the prior year building gain, pretax earnings from continuing operations grew 6%, net earnings from continuing operations grew 5%, and diluted earnings per share from continuing operations increased 10% to $2.39 from $2.18.

ADP acquired 13.8 million shares of its stock for treasury at a cost of about $550 million during the fiscal year. Cash and marketable securities balances included approximately $730 million of assets related to the outstanding commercial paper borrowing as of June 30, 2009, which was repaid on July 1, 2009. This borrowing is a normal part of the client funds extended investment strategy. Cash and marketable securities were $2.4 billion, or $1.7 billion excluding the assets related to the commercial paper borrowing, at June 30, 2009.

For the fourth quarter of fiscal 2009, revenues declined 5% to $2.1 billion compared with the fourth quarter of fiscal 2008. Revenue growth was negatively impacted by continued severe economic conditions and about 4 percentage points from unfavorable foreign exchange rates. As reported, pretax earnings from continuing operations grew 2%, net earnings from continuing operations grew 54%, and diluted earnings per share from continuing operations of $0.69 increased 60%, from $0.43 per share a year ago on fewer shares outstanding. Excluding the current year favorable tax settlements and the prior year building gain described above, pretax earnings from continuing operations grew 7%, net earnings from continuing operations grew 5%, and diluted earnings per share from continuing operations increased 7% to $0.45 from $0.42.

Fourth Quarter and Fiscal Year 2009 Discussion

Commenting on the results, Mr. Butler said, "The downturn in the economy during fiscal 2009 has been the most profound in decades. Headwinds from the global recession as well as unfavorable foreign exchange rates began to impact ADP's growth earlier this fiscal year. As anticipated, our key business metrics for Employer Services continued to show year-over-year declines in the fourth quarter. The selling environment remained challenging during the fourth quarter resulting in year-over-year declines in new business sales for both the fourth quarter and the full year that were larger than we anticipated. Growth for Dealer Services continued to be negatively impacted by the difficulties facing the automotive industry. As revenues are expected to remain under pressure near-term, ADP took appropriate measures during the fourth quarter to reduce its expense structure. At the same time, ADP continued to invest in new products and client facing resources. For the fiscal year, service-related expenses in Employer Services increased about 9% from a year ago as we are committed to enhancing the service we provide our clients especially during these challenging times.

Employer Services

"Employer Services' revenues were flat for the fourth quarter, and grew 4% for the fiscal year, all organic. In the United States, revenues from our traditional payroll and payroll tax filing business declined 4% for the fourth quarter, and were flat for the year. Beyond payroll revenues, excluding PEO Services' revenues, grew 4% for the fourth quarter and 8% for the year. As anticipated, the number of employees on our clients' payrolls in the United States declined 5.7% for the fourth quarter and 2.5% for the year, as measured on a same-store-sales basis for our clients on our Auto Pay platform. Worldwide client retention declined 1.2 percentage points for the year. Employer Services' pretax margin improved 275 basis points for the fourth quarter and 160 basis points for the year. The full year pretax margin expansion benefited from operating leverage and a decline in selling and implementation expenses from lower sales volumes. The fourth quarter pretax margin expansion also resulted from a decline in selling and implementation expenses as well as a reduction in management incentive compensation expenses.

"Combined Employer Services and PEO Services worldwide new business sales declined 29% for the quarter and 15% for the year. New business sales represent annualized recurring revenues anticipated from new orders, and totaled $982 million for the year. Sales results for all markets were down year over year, but were most negatively impacted up-market where larger companies continued to delay outsourcing decisions due to the difficult economic conditions.

PEO Services

"PEO Services' revenues increased 7% for the fourth quarter and 12% for the year, all organic. PEO Services' pretax margin was flat for the fourth quarter and improved 10 basis points for the year. Average worksite employees paid by PEO Services increased 4% for the fourth quarter, and 10% for the year, to approximately 194,000 and 193,000, respectively.

Dealer Services

"Dealer Services' revenues declined 9% for the fourth quarter, 11% organically, and 3% for the year, 4% organically. Revenues were negatively impacted by ongoing dealership consolidations and closings, and lower transactional revenues as well as dealerships cutting discretionary spending. Additionally, as expected, consulting revenues and software license fees from an international non-core business declined due to some large projects completed in the prior fiscal year, which resulted in a more difficult year over year comparison in the quarter. Dealer Services' pretax margin declined 120 basis points for the fourth quarter and 20 basis points for the year. The full year pretax margin declined on lower revenues and the impact of the January 2009 Automaster Oy acquisition, partially offset by strict cost reduction measures. In addition to these items, the fourth quarter decline in pretax margin resulted from the decline in the international non-core revenues and an increase in our provision for allowance for doubtful accounts relating to the automotive bankruptcies.

Interest on Funds Held for Clients, Interest Income on Corporate Funds, and Interest Expense

"The 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 credit quality of the investment portfolio is predominantly AAA/AA.

"For the fourth quarter, interest on funds held for clients declined $23.4 million, or 13.8%, from $169.7 million to $146.3 million, due to a decline of 30 basis points in the average interest yield to 3.9%, and a decline of 7.4% in average client funds balances from $16.1 billion to $15.0 billion. Interest expense declined $8.9 million, or 72%, from $12.4 million to $3.5 million. The decline in interest expense was primarily due to a decline of 180 basis points in average commercial paper borrowing rates to 0.3%, partially offset by higher average daily commercial paper borrowings which increased $0.3 billion, from $1.3 billion to $1.6 billion.

"For the fiscal year, interest on funds held for clients declined $74.7 million, or 10.9%, from $684.5 million to $609.8 million, due to a decline of 40 basis points in the average interest yield to 4.0%, and a decline of 3.1% in average client funds balances from $15.7 billion to $15.2 billion. Interest expense declined $47.2 million, or 59%, from $80.5 million to $33.3 million. The decline in interest expense was primarily due to a decline of 320 basis points in average commercial paper borrowing rates to 1.0%, partially offset by higher average daily commercial paper borrowings which increased $0.5 billion, from $1.4 billion to $1.9 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 2010 Forecast

"Our fiscal 2010 forecasts anticipate that severely negative economic conditions continue. As such, our forecasts assume a worsening of our business metrics in the first half of the year as compared with the first half of fiscal 2009, with particularly tough year-over-year comparisons expected in the first quarter

 -- Total revenues - decline 1% to 4%
 -- Diluted earnings per share - $2.29 to $2.39, compared with $2.39
    earnings per share from continuing operations in fiscal 2009
    excluding favorable tax settlements in the fourth quarter.
 -- Employer Services - decline in revenues of 1% to 3%
     * Pays per control - decline of 5% to 6%
     * Client revenue retention - flat to down 1 percentage point
 -- PEO Services - revenue growth of up to 4%
 -- Employer Services and PEO Services new business sales - about flat
    compared to $982 million sold in fiscal 2009
 -- Dealer Services - decline in revenues of 4% to 8%
 -- We anticipate no improvement in pretax margins given the continued
    difficult economic environment anticipated for fiscal 2010

"Interest on funds held for clients is expected to decline $60 to $70 million, or 10% to 11%, from $609.8 million in fiscal 2009. This is based on an approximate 20 basis point decline in the expected average interest yield to about 3.8%, and a 4% to 6% decline in average client funds balances. The interest assumptions in our forecasts are based on Fed Funds futures contracts and forward yield curves as of July 24, 2009. The Fed Funds futures contracts anticipate two increases of 25 basis points each in February and May 2010, ending the fiscal year with a Fed funds rate of 0.75%. The three-and-a-half and five-year U.S. government agency rates based on the forward yield curves as of July 24, 2009 were used to forecast new purchase rates for the client extended and client long portfolios, respectively.

"We expect interest expense to decline about $20 million from $33.3 million in fiscal 2009 primarily from lower interest expense on our short-term financing related to our ongoing client funds extended investment strategy. Our average commercial paper borrowing rates are expected to decrease approximately 50 basis points to about 0.5% and we anticipate a decline of up to $0.1 billion in average daily commercial paper borrowings to $1.8 to 1.9 billion.

"While we anticipate a challenging year ahead as a result of the difficult economic landscape, our business model remains intact. A high percentage of recurring revenues, healthy margins, strong and consistent cash flows and low capital expenditure requirements combined with a strong balance sheet and a AAA credit rating have enabled us to continually invest in our strategic growth program. We are doing the right things now to drive the future growth of ADP and I remain optimistic about ADP's long-term potential," Mr. Butler concluded.

 (In millions, except per share amounts)
 (Unaudited)

 The following table reconciles the Company's results for the quarter
 and fiscal years ended June 30, 2009 and 2008 to adjusted results
 that exclude the impact of tax settlements and a gain on the sale of
 a building. The Company uses adjusted earnings from continuing
 operations and adjusted diluted EPS from continuing operations, among
 other measures, to evaluate the Company's operating performance in
 the absence of certain items and for planning and forecasting of
 future periods. The Company believes that the adjusted results
 provide relevant and useful information for investors because it
 allows investors to view performance in a manner similar to the
 method used by the Company's management, improves their ability to
 understand the Company's operating performance and makes it easier to
 compare the Company's results with other companies. Since adjusted
 earnings from continuing operations and adjusted diluted EPS are not
 measures of performance calculated in accordance with GAAP, they
 should not be considered in isolation of, or as a substitute for,
 earnings from continuing operations and diluted EPS from continuing
 operations as indicators of operating performance and they may not be
 comparable to similarly titled measures employed by other companies.
