[1] Cash equivalents are comprised of certificates of deposit, time deposits and other interest-bearing investments with original maturity dates of 90 days or less, all of which are recorded at cost, which approximates fair value.

[2] Time deposits, included in Other current assets on the Condensed Consolidated Balance Sheet, are comprised of deposits with original maturities of more than 90 days but less than one year, all of which are recorded at cost, which approximates fair value.

[3] Notes receivable represent held-to-maturity securities, which arose from the sale of nonstrategic timberlands and related assets. The notes are backed by irrevocable standby letters of credit issued by money center banks. We collected in cash the $220 million face value of the note receivable that matured on July 7, 2011. The remaining note receivable, with a face value of $397 million, matures in September 2014. At September 30, 2011 a consolidated variable interest entity (“VIE”) has an outstanding long-term monetization loan secured by the remaining note held by this VIE. As of

[4] Short-term debt is recorded at cost, which approximates fair value.(e) Long-term debt excludes the monetization loan and includes the portion payable within the next twelve months ($670 million at September 30, 2011 and $265 million at December 31, 2010). Fair values were es

[5] Long-term debt excludes the monetization loan and includes the portion payable within the next twelve months ($670 million at September 30, 2011 and $265 million at December 31, 2010). Fair values were estimated based on quoted prices for financial instruments for which all significant inputs were observable, either directly or indirectly.

[6] The redeemable preferred securities are not traded in active markets. Accordingly, their fair values were calculated using a pricing model that compares the stated spread to the fair value spread to determine the price at which each of the financial instruments should trade. The model used the following inputs to calculate fair values: face value, current benchmark rate, fair value spread, stated spread, maturity date and interest payment dates. We determined the fair value and carrying amount of the redeemable common securities were $35 million at September 30, 2011 and December 31, 2010 based on various inputs, including an independent third-party appraisal, adjusted for current market conditions.
