Fair Value of Pension Plan Assets and Obligations

In our year-end reporting process, we estimate the fair value of pension plan assets based upon the information available at that time. For certain assets, primarily private equity funds, the information available consists of net asset values as of an interim date, cash flows between the interim date and the end of the year and market events. We evaluate the year-end estimated fair value of pension plan assets in the second quarter of each year to incorporate final net asset values reflected in financial statements received after we have filed our Annual Report on Form 10-K.
