Item 8.01. Other Events

On May 28, 2013, PG&E Corporation’s subsidiary, Pacific Gas and Electric Company, commenced an offer to purchase (the “Tender Offer”) for cash up to $500 million aggregate principal amount of the $1,000,000,000 aggregate principal amount of its outstanding 4.80% senior notes due 2014 (the “Tender Notes”). The consideration for each $1,000 principal amount of Tender Notes validly tendered and not validly withdrawn before 5:00 p.m. New York City time, on June 10, 2013 (as may be extended, the “Early Tender Date”) and accepted for purchase pursuant to the Tender Offer will be determined by reference to a fixed spread of 0.20% over the yield based on the bid-side price of the 0.25% U.S. Treasury Notes due February 28, 2014 as calculated by Citigroup Global Markets Inc. and Merrill Lynch, Pierce, Fenner & Smith Incorporated at 1:00 p.m., New York City time, on the Early Tender Date. The consideration payable for the Tender Notes includes an early tender premium of $30.00 per $1,000 principal amount of Tender Notes accepted for purchase. Holders of Tender Notes tendered after the Early Tender Date but before 11:59 p.m., New York City time, on June 24, 2013 (as may be extended, the “Expiration Time”) and accepted for purchase pursuant to the Tender Offer will not receive the early tender premium. In addition, all holders of Tender Notes accepted for purchase pursuant to the Tender Offer will receive accrued and unpaid interest on their Tender Notes from the last interest payment date to the applicable settlement date. No tenders submitted after the Expiration Time will be valid.
