Our product revenue reserves are based on estimates of the amounts earned or to be claimed on the related sales. These estimates take into consideration our historical experience, current contractual and statutory requirements, specific known market events and trends and forecasted customer buying patterns. Actual amounts may ultimately differ from our estimates. If actual results vary, it will result in an adjustment to these estimates, which could have an effect on earnings in the period of adjustment.

During the six months ended June 30, 2011, we reduced our reserves for contractual adjustments by $8.4 million, which was primarily due to a revision of our previous estimates associated with the impact of healthcare reform.
