Commenting on the results, CSC Chairman and Chief Executive Officer, Michael Laphen said, “We had a solid quarter and an outstanding year marked by robust cash generation, further increased profitability, and a significantly strengthened balance sheet. I am especially pleased with our success in capturing new business with another $4.3 billion of new awards in the quarter bringing our total year result to $19.2 billion, a record for CSC and $3 billion above last year.”

New Business Awards

The breakdown of the $4.3 billion of new business awards in the quarter by our three lines of business is as follows: North American Public Sector (NPS) contributed $1.4 billion ($7.1 billion for the full year), Business Solutions and Services (BSS) reported $0.8 billion ($3.4 billion for the full year), and Managed Services Sector (MSS) closed $2.1 billion of new business ($8.7 billion for the full year).

Business Outlook

“Our fourth quarter revenue reflects a sequential increase of 7%, and that, coupled with the $19.2 billion of new business awards, positions us for a return to growth in Fiscal Year 2011” said Laphen. “As the world economies gradually improve, our financial strength, market position, and innovative solutions will stimulate expansion across our three lines of business.”

Lines of Business

For the quarter, NPS revenue was $1.61 billion (up 8.8% sequentially and up 6.1% from fourth quarter last year), MSS revenue was $1.69 billion (up 4.4% sequentially and up 4.7% from fourth quarter last year) and BSS revenue was $0.97 billion (up 9.5% sequentially and down 4.1% from fourth quarter last year).

Dividend Declaration

Laphen added, “Our focus on operational and financial excellence and particularly cash generation gives us the confidence that we can adequately fund the necessary investments in technology and strategic acquisitions while enhancing our return to investors.

Therefore, as a demonstration of that confidence in performance and commitment to our shareholders, the company’s Board of Directors authorized and declared a quarterly dividend of $0.15 per share payable July 2010.”

Non-GAAP Financial Measures

The following tables reconcile operating income and free cash flow to the most directly comparable financial measure calculated and presented in accordance with accounting principles generally accepted in the United States (GAAP). CSC management believes that these non-GAAP financial measures provide useful information to investors regarding the Company’s financial condition and results of operations as they provide another measure of the Company’s profitability and ability to service its debt, and are considered important measures by financial analysts covering CSC and its peers. Management uses operating income to evaluate business unit financial performance and it is one of the measures used in assessing management performance. One of the limitations associated with the use of operating income (as compared to reported earnings) is that it does not reflect the complete financial results of the Company. CSC compensates for these limitations by providing a reconciliation between operating income and reported earnings.
