Chevron’s Acquisition of Unocal
Unocal ceased to exist as an independent company on August 11, 2005 and its shares were de-listed from the New York
Stock Exchange. The new firm is known as Chevron. In a highly politicized transaction, Chevron battled Chinese oil-
producer, CNOOC, for almost four months for ownership of Unocal. A cash and stock bid by Chevron, the nation’s second
largest oil producer, made in April valued at $61 per share was accepted by the Unocal board when it appeared that
CNOOC would not counter-bid. However, CNOOC soon followed with an all-cash bid of $67 per share. Chevron amended
the merger agreement with a new cash and stock bid valued at $63 per share in late July. Despite the significant difference
in the value of the two bids, the Unocal board recommended to its shareholders that they accept the amended Chevron bid
in view of the growing doubt that U.S. regulatory authorities would approve a takeover by CNOOC.
This mix of cash and stock implied that Chevron would pay approximately $7.5 billion (i.e., $27.60 x 272 million
Unocal shares outstanding) in cash and issue approximately 168 million shares of Chevron common stock (i.e., .618 x 272
million of Unocal shares) valued at $57.28 per share as of July 22, 2005. The implied value of the merger on that date was
$17.1 billion (i.e., $27.60 x 272 million Unocal common shares outstanding plus $57.28 x 168 million Chevron common
shares). An increase in Chevron’s share price to $63.15 on August 10, 2005, the day of the Unocal shareholders’ meeting,
boosted the value of the deal to $18.1 billion.
The agreement of purchase and sale between Chevron and Unocal contained a “proration clause.” This clause enabled
Chevron to limit the amount of total cash it would payout under those options involving cash that it had offered to Unocal
shareholders and to maintain the “blended” rate of $63 it would pay for each share of Unocal stock. Approximately 242
million Unocal shareholders elected to receive all cash for their shares, 22.1 million opted for the all-stock alternative, and
10.1 million elected the cash and stock combination. No election was made for approximately .3 million shares. Based on
Exhibit 1. Prorating All-Cash Elections
1. Determine the available cash election amount (ACEA): Aggregate cash amount minus the amount of cash
to be paid to Unocal shareholders selecting the combination of cash and stock (i.e., Option 3).
ACEA = $27.60 x 272 million (Unocal shares outstanding) – 10.1
million (shares electing cash and stock option) x $27.60
