Chevron Corp. (CVX)

Subsidiary and Affiliated Companies

The Consolidated Financial Statements include the accounts of controlled subsidiary companies more than 50 percent-owned and any variable-interest entities in which Chevron is the primary beneficiary. Undivided interests in oil and gas joint ventures and certain other assets are consolidated on a proportionate basis. Investments in and advances to affiliates in which Chevron has a substantial ownership interest of approximately 20 percent to 50 percent, or for which Chevron exercises significant influence but not control over policy decisions, are accounted for by the equity method. As part of that accounting, Chevron recognizes gains and losses that arise from the issuance of stock by an affiliate that results in changes in Chevron's proportionate share of the dollar amount of the affiliate's equity currently in income.

Investments in affiliates are assessed for possible impairment when events indicate that the fair value of the investment may be below Chevron's carrying value. When such a condition is deemed to be other than temporary, the carrying value of the investment is written down to its fair value, and the amount of the write-down is included in net income. In making the determination as to whether a decline is other than temporary, Chevron considers such factors as the duration and extent of the decline, the investee's financial performance, and Chevron's ability and intention to retain its investment for a period that will be sufficient to allow for any anticipated recovery in the investment's market value. The new cost basis of investments in these equity investees is not changed for subsequent recoveries in fair value.

Differences between Chevron's carrying value of an equity investment and its underlying equity in the net assets of the affiliate are assigned to the extent practicable to specific assets and liabilities based on Chevron's analysis of the various factors giving rise to the difference. When appropriate, Chevron's share of the affiliate's reported earnings is adjusted quarterly to reflect the difference between these allocated values and the affiliate's historical book values.

Short-Term Investments

All short-term investments are classified as available for sale and are in highly liquid debt securities. Those investments that are part of Chevron's cash management portfolio and have original maturities of three months or less are reported as "Cash equivalents." Bank time deposits with maturities greater than 90 days are reported as "Time deposits." The balance of short-term investments is reported as "Marketable securities" and is marked-to-market, with any unrealized gains or losses included in "Other comprehensive income."
