We have an ongoing authorization, amended in November 2005, from our Board of Directors to repurchase up to $25 billion in shares of our common stock in open market or negotiated transactions. As of December 27, 2008, $7.4 billion remained available for repurchase under the existing repurchase authorization. A portion of our purchases in 2008 was executed under privately negotiated forward purchase agreements. In the third quarter of 2008, we executed a forward purchase agreement with Lehman Brothers OTC Derivatives Inc. (Lehman Brothers) in which we prepaid $1.0 billion and received an equivalent $1.0 billion of cash collateral from Lehman Brothers. However, in the fourth quarter, Lehman Brothers failed to deliver shares of Intel common stock, and we foreclosed on the $1.0 billion collateral.

Common stock repurchases under our authorized plan in each quarter of 2008 were as follows (in millions, except per share amounts):

We did not make any common stock repurchases under our authorized plan during the fourth quarter of 2008.

For the majority of restricted stock units granted, the number of shares issued on the date the restricted stock units vest is net of the statutory withholding requirements that we pay on behalf of our employees. These withheld shares are not included in the common stock repurchase totals in the tables above. For further discussion, see "Note 20: Common Stock Repurchases" in Part II, Item 8 of this Form 10-K.
