Commitments and Contingencies

We have committed to make potential future milestone payments to third parties as part of in-licensing and development programs primarily related to research and development agreements. Potential future payments generally become due and payable only upon the achievement of certain developmental, regulatory and/or commercial milestones, such as achievement of regulatory approval, successful development and commercialization of products, and subsequent product sales. Because the achievement of these milestones is neither probable nor reasonably estimable, we have not recorded a liability on the balance sheet for any such contingencies.

As of June 30, 2012, if all such milestones are successfully achieved, the potential future milestone and other contingency payments we could be required to make under certain contractual agreements are approximately $235.4 million in aggregate, of which $5.3 million are expected to be paid within the next 12 months.

We have committed to make future minimum payments to third parties for certain inventories in the normal course of business. The minimum purchase commitments total approximately $191.4 million as of June 30, 2012.

As of June 30, 2012, commitments associated with capital investments on the BYDUREON pen device are $3.4 million.

In December 2011, we entered into an Amended and Restated Letter of Credit and Cash Collateral Agreement with Bank of America which provides for the issuance of letters of credit under which we agreed to deliver cash collateral to Bank of America, the total of which equaled $10.7 million as of June 30, 2012. Additionally, as of June 30, 2012 we had issued $10.5 million of standby letters of credit, primarily in connection with office leases.
