Item 1.01 Entry into a Material Definitive Agreement

On April 2, 2011, we amended our Wafer Supply Agreement with GLOBALFOUNDRIES, Inc. (“GF”). The primary effect of the amendment was to change the pricing methodology applicable to wafers delivered in 2011 for our microprocessor and accelerated processing unit (“APU”) products. The amendment also modifies our existing commitments regarding the production of certain graphics processing unit (“GPU”) and chipset products at GF. Pursuant to the amendment, GF has committed to provide us with, and we have committed to purchase, a fixed number of 45nm and 32nm wafers per quarter in 2011. We will pay GF a fixed price for 45nm wafers delivered in 2011. Our price for 32nm wafers will vary based on the wafer volumes and manufacturing yield of such wafers. In addition, we also agreed to pay an additional quarterly amount to GF during 2012 if GF meets specified conditions related to continued availability of 32nm capacity as of the beginning of 2012. We expect GF will meet the conditions to earn these payments. For 2012, pursuant to the amended Wafer Supply Agreement, we will resume compensating GF on a cost-plus basis to manufacture the wafers for our microprocessor and APU products. We currently estimate that we will pay GF approximately $1.1 to $1.5 billion in 2011 and $1.5 to $1.9 billion in 2012 for wafer purchases under the Wafer Supply Agreement, as amended. In 2010, we paid GF approximately $1.2 billion for wafer purchases. We based our 2011 and 2012 estimated costs in part on our current expectations regarding GF’s manufacturing yields and wafer volumes. These costs could increase or decrease as a result of variations in those yields and several other factors including our current expectations regarding demand for our products. We are not able to meaningfully quantify or estimate our purchase obligations to GF beyond 2012, but we expect that our future purchases from GF will continue to be material under the Wafer Supply Agreement.

The foregoing description does not purport to be complete and is qualified in its entirety by reference to the Wafer Supply Agreement amendment, a copy of which will be filed with the Company’s next quarterly report on Form 10-Q.

On December 27, 2010, we filed a Form 8-K to disclose, among other things, the contribution of all of the outstanding ordinary shares of GLOBALFOUNDRIES Singapore Pte. Ltd. by ATIC International Investment Company LLC to GF in exchange for newly issued shares of GF Class A Preferred Shares (the “GFS Contribution”). In that Form 8-K, we indicated that as a result of the GFS Contribution, we expected to recognize a non-cash gain related to the dilution of our equity interest in GF in the first fiscal quarter of 2011, the exact amount of which we could not determine at that time. We have now determined that we will recognize a non-cash gain, net of certain costs, of approximately $492 million, which will be reflected in the Equity in net income (loss) of investee line of our Consolidated Statements of Operations for the first fiscal quarter of 2011.
