pursuant to our stock repurchase program. We repurchased 43.3 million shares for $1.0 billion, 225.6 million shares for $4.0 billion, and 97.3 million shares for $2.0 billion in fiscal 2010, 2009 and 2008, respectively. Our stock repurchase authorization does not have an expiration date and the pace of our repurchase activity will depend on factors such as our working capital needs, our cash requirements for acquisitions and dividend repayments, our debt repayment obligations (described further below), our stock price, and economic and market conditions. Our stock repurchases may be effected from time to time through open market purchases or pursuant to a Rule 10b5-1 plan. Our stock repurchase program may be accelerated, suspended, delayed or discontinued at any time.

Cash Dividends :    In fiscal 2010, we declared and paid cash dividends of $0.20 per share that totaled $1.0 billion, which is an increase in comparison to fiscal 2009 in which we declared and paid the first dividend in our history to our common stockholders of $0.05 per share, which totaled $250 million. In June 2010, our Board of Directors declared a quarterly cash dividend of $0.05 per share of outstanding common stock payable on August 4, 2010 to stockholders of record as of the close of business on July 14, 2010. Future declarations of dividends and the establishment of future record and payment dates are subject to the final determination of our Board of Directors.

Contractual Obligations:     The contractual obligations presented in the table below represent our estimates of future payments under fixed contractual obligations and commitments. Changes in our business needs, cancellation provisions, changing interest rates and other factors may result in actual payments differing from these estimates. We cannot provide certainty regarding the timing and amounts of payments. We have presented below a summary of the most significant assumptions used in preparing this information within the context of our consolidated financial position, results of operations and cash flows. The following is a summary of our contractual obligations as of May 31, 2010:

As of May 31, 2010, we have $2.5 billion of unrecognized tax benefits recorded on our consolidated balance sheet. We have reached certain settlement agreements with relevant taxing authorities to pay approximately $79 million of these liabilities (these amounts have been excluded from the table above due to the uncertainty of when they might be settled). Although it remains unclear as to when payments pursuant to these agreements will be made, some or all may be made in fiscal 2011. We cannot make a reasonably reliable estimate of the period in which the remainder of our unrecognized tax benefits will be settled or released with the relevant tax authorities, although we believe it is reasonably possible that certain of these liabilities could be settled or released during fiscal 2011.

Separately, in the fourth quarter of fiscal 2010, we agreed to acquire Phase Forward Incorporated, a provider of applications for life sciences companies and healthcare providers, for $17.00 per share in cash, amounting to approximately $810
