Employee Benefit Plans, Policy

We are required by applicable GAAP to:

recognize an asset for a plan's overfunded status or a liability for a plan's underfunded status in the statement of financial position;
measure a plan's assets and its obligations that determine its funded status as of the end of the fiscal year (with limited exceptions); and

recognize changes in the funded status of a defined benefit postretirement plan in the year in which the changes occur. Generally, those changes are reported in other comprehensive income and as a separate component of shareholders' equity.

The information presented below covers the employee benefit plans of Sempra Energy and its principal subsidiaries, as detailed following.

Pension and other postretirement benefits costs and obligations are dependent on assumptions used in calculating such amounts. These assumptions include

discount rates
expected return on plan assets
health-care cost trend rates
mortality rates
compensation increase rates

payout elections (lump sum or annuity)

SHAREHOLDERS' EQUITY AND EARNINGS PER SHARE (Policies)	Dec. 31, 2011
Significant Accounting Policies
Earnings Per Share, Policy	Basic earnings per common share (EPS) is calculated by dividing earnings attributable to common stock by the weighted-average number of common shares outstanding for the year. Diluted EPS includes the potential dilution of common stock equivalent shares that could occur if securities or other contracts to issue common stock were exercised or converted into common stock.

COMMITMENTS AND CONTINGENCIES (Policies)	Dec. 31, 2011
Significant Accounting Policies
Environmental Issues, Policy	At the Sempra Utilities, costs that relate to current operations or an existing condition caused by past operations are generally recorded as a regulatory asset due to the probability that these costs will be recovered in rates. We record environmental liabilities at undiscounted amounts when our liability is probable and the costs can be reasonably estimated.
Legal Proceedings, Policy	We accrue losses for legal proceedings when it is probable that a loss has been incurred and the amounts of the loss can be reasonably estimated.
