Note:

For the
purpose of computing Pacific Gas and Electric Companys ratios of earnings to combined fixed charges and preferred stock dividends, earnings represent net income adjusted for the income or loss from equity investees of less than
100% owned affiliates, equity in undistributed income or losses of less than 50% owned affiliates, income taxes and fixed charges (excluding capitalized interest). Fixed charges include interest on long-term debt and short-term
borrowings (including a representative portion of rental expense), amortization of bond premium, discount and expense, interest on capital leases, AFUDC debt, and earnings required to cover the preferred stock dividend requirements and preferred
security distribution requirements of majority-owned trust. Preferred stock dividends represent tax deductible dividends and pre-tax earnings that are required to pay the dividends on outstanding preferred securities. Fixed charges
exclude interest on tax liabilities.
