ADP Reports Second Quarter Fiscal 2013 Results

Confirms Fiscal 2013 Revenue and EPS Guidance

Revenues Rise 7%, 6% Organic

EPS From Continuing Operations Declined 5%, Increased 7% Excluding Prior Year Gain

ROSELAND, N.J., Feb. 5, 2013 (GLOBE NEWSWIRE) -- ADP^® (Nasdaq:ADP) reported revenue growth of 7%, 6% organic, to $2.7 billion for the second fiscal quarter ended December 31, 2012, Carlos Rodriguez, president and chief executive officer, announced today. The second quarter of fiscal 2012 included a pretax gain of $66 million, $41 million after tax, on a sale of assets. As reported, including the gain, pretax earnings from continuing operations decreased 8% and pretax margin declined 320 basis points. Net earnings from continuing operations decreased 6% and diluted earnings per share from continuing operations of $0.72 decreased 5% from $0.76 a year ago on fewer shares outstanding. 

Excluding the prior year gain, pretax earnings from continuing operations increased 4%, pretax margin declined 60 basis points, net earnings from continuing operations increased 6%, and diluted earnings per share from continuing operations of $0.72 increased 7% from $0.67 a year ago. Fiscal year-to-date through February 1, 2013 ADP acquired 5.9 million shares of its stock for treasury at a cost of $341 million. Cash and marketable securities were $1.5 billion at December 31, 2012.

Second Quarter Discussion

Commenting on the results, Mr. Rodriguez said, "I am pleased with ADP's second quarter results.    Our business segments performed well driving solid revenue growth and pretax margin expansion. Combined worldwide new business bookings for Employer Services and PEO Services grew 5%. With 9% growth in new business bookings through the first half of the fiscal year, we are on track to achieve our full year outlook of 8% to 10% growth.

"Previously communicated challenges and tough comparisons we faced heading into the quarter affected the company's results, including:

• The gain on a sale of assets in the prior year second quarter negatively impacted growth in pretax earnings from continuing operations 12%, pretax margin 260 basis points, and diluted earnings per share from continuing operations $0.08, or 12%.
• Unfavorable foreign exchange rates negatively impacted revenue growth 0.5% with minimal impact on earnings. 
• The decline in high-margin interest revenues due to the lower average yield on client funds balances negatively impacted revenue growth 1%, partially offset by growth in average client funds balances. The client funds extended investment strategy, which is primarily driven by interest on client funds, negatively impacted growth in pretax earnings from continuing operations 4%, pretax margin 110 basis points, and diluted earnings per share from continuing operations $0.03, or 4%. 
• Foregone revenues and earnings related to the fiscal 2012 second quarter sale of assets and the expiration of certain employment tax credits within our Tax Credit Services business negatively impacted revenue growth 1%, growth in pretax earnings from continuing operations 2%, pretax margin 30 basis points, and diluted earnings per share nearly $0.02, or 3%.
• Fiscal 2012 acquisitions contributed 1% to total revenue growth and negatively impacted pretax margins 20 basis points with minimal impact on earnings.

Employer Services

"Employer Services' revenues grew 7% for the second quarter, 6% organically, compared to last year's second quarter. The number of employees on our clients' payrolls in the United States increased 2.6% for the quarter as measured on a same-store-sales basis for our clients on our AutoPay platform. Worldwide client retention increased 0.8 percentage points compared with a year ago. As anticipated, Employer Services' pretax margin expanded 70 basis points for the quarter including a 50 basis point drag from fiscal 2012 acquisitions. Increased operating scale and sales efficiencies contributed to the pretax margin improvement.

PEO Services

"PEO Services' revenues increased 13% for the second quarter, all organic, compared to last year's second quarter.  PEO Services' pretax margin increased 40 basis points for the quarter due to an easier year-over-year comparison and slower growth in pass-through costs. Average worksite employees paid by PEO Services increased 10% for the quarter to approximately 276,000.

Dealer Services

"Dealer Services' revenues grew 11% for the second quarter, 9% organically, compared to last year's second quarter. Organic revenues benefited from increased advertising in Digital Marketing and increased software license fees in our international business. Dealer Services' pretax margin improved 180 basis points for the quarter benefiting from increased operating scale and an increase in certain non-recurring high-margin revenues.

Interest on Funds Held for Clients

"The safety, liquidity, and diversification 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 second quarter, interest on funds held for clients declined $16.2 million, or 14%, from $117.9 million a year ago to $101.7 million, due to a decline of about 60 basis points in the average interest yield to 2.4%, partially offset by an increase of 9% in average client funds balances from $15.6 billion to $17.0 billion.

Discontinued Operations

"On December 17, 2012, ADP completed the sale of the Taxware Enterprise Service business (Taxware) which was previously reported within the Employer Services segment. Taxware generated $50 million in revenues and approximately $0.02 of earnings per share in fiscal 2012. The results of operations for this business are reported within discontinued operations in the fiscal 2013 and 2012 results within this release.  ADP recorded a net gain on the sale of $58.8 million, or $36.7 million after tax, within discontinued operations in the second quarter of fiscal 2013.

Fiscal 2013 Forecast

"Our fiscal 2013 forecasts assume no changes in the current economic environment. We have maintained our guidance for total company revenue and earnings per share growth and we continue to anticipate driving good pretax margins in the business segments, although we anticipate a decline in total ADP pretax margin.  Our forecasts continue to be impacted by a lower expected average yield on the client funds portfolio due to continued low market interest rates, and tough year-over-year comparisons from certain fiscal 2012 items as detailed in the tables below.  We continue to anticipate an improvement in the effective tax rate of approximately 30 basis points from 34.5% last year. Our forecasts exclude the results of discontinued operations.

Revenues - We continue to anticipate 5% - 7% growth.

Pretax margins – We anticipate a decline of about 30 to 40 basis points from 19.2% last year which excludes the gain recorded in the second quarter of fiscal 2012.

Diluted earnings per share from continuing operations – We continue to anticipate 5% - 7% growth compared to $2.72 in fiscal 2012, which excludes the gain recorded in the second quarter of fiscal 2012.

 "The impacts noted above from the expected drag from fiscal 2012 acquisitions as well as the negative year-over-year comparisons from the fiscal 2012 second quarter sale of assets and the expiration of certain employment tax credits within our Tax Credit Services business are reflected in the segment forecasts provided below.

• Employer Services – revenue growth of 6% to 7% with pretax margin expansion of at least 50 basis points

• Pays per control – up 2.0% to 3.0% for the year

• PEO Services – revenue growth of 12% to 13% with slight pretax margin expansion
• Employer Services and PEO Services new business sales – 8% to 10% growth compared to over $1.2 billion sold in fiscal 2012
• Dealer Services – revenue growth of 8% to 9%, with pretax margin expansion of over 100 basis points

"The interest assumptions in our forecasts are based on Fed Funds futures contracts and forward yield curves as of February 1, 2013. The Fed Funds futures contracts used in the client short and corporate cash interest income forecasts do not anticipate any changes during the fiscal year in the Fed Funds target rate. The three-and-a-half and five-year U.S. government agency rates based on the forward yield curves as of February 1, 2013 were used to forecast new purchase rates for the client extended, corporate extended, and client long portfolios, respectively.

• Interest on funds held for clients is expected to decline about $75 million, or 15%, from $493.3 million in fiscal 2012 to about $420 million. This forecast is based on a decline of about 60 basis points in the expected average interest yield to 2.2%, partially offset by 5% to 7% anticipated growth in average client funds balances to $18.8 to $19.1 billion.
• Interest income on corporate funds is expected to decline approximately $20 million from $85.2 million in fiscal 2012. Included in interest income on corporate funds is interest income related to the extended investment strategy, which is expected to decline about $10 million to approximately $55 million.
• In combination, we expect the total impact related to the client funds extended investment strategy to be a decline of $85 to $90 million from $556 million in fiscal 2012. Our prior forecast anticipated a decline of $80 to $85 million.

"I am cautious as economic growth continues to lag historic levels, but I am pleased with our solid execution in our businesses.  I am confident that ADP is well positioned to navigate the uncertainty of the global economy. As a leading global Human Capital Management solutions provider we are focused on successfully executing against our four strategic pillars for growth. Driving product innovation and enhancing our distribution and service capabilities are the right things to do to continue to grow the business long-term," Mr. Rodriguez concluded.
