Cautionary Language Regarding
Forward-Looking Statements
This presentation contains forward-looking statements regarding the estimated future costs Pacific Gas and Electric
Company (“Utility”) will incur associated with its natural gas pipeline operations, including forecasted costs under the
Utility’s proposed implementation plan to conduct hydrostatic pressure tests and/or replace pipelines (“Implementation
Plan”), estimated third-party liabilities related to the rupture of a natural gas pipeline that occurred in a residential area of
San Bruno, California on September 9, 2010 (“San Bruno Accident”), potential future insurance recoveries for third-party
liability costs related to the San Bruno accident, and the estimated financial impact that these matters will have on PG&E
Corporation’s and the Utility’s income available for common shareholders. These statements are based on various
assumptions and management’s current knowledge of relevant facts. Actual results could differ materially based on
various factors, including:
• how the determination by the National Transportation Safety Board (“NTSB”) of the probable cause of the San Bruno accident will affect the
outcome of pending and future regulatory, legislative, or other proceedings or investigations related to the San Bruno accident and the safety of
the Utility’s natural gas transmission pipelines;
• the scope, timing of the final Implementation Plan that is approved by the CPUC and whether the CPUC approves the Utility’s proposed
allocation of Implementation Plan-related costs between shareholders and ratepayers;
• the actual level of costs incurred outside the scope of the Implementation Plan, such as costs to gather pipeline documents, conduct additional
leak surveys and inspections, engage in customer outreach, test in-line camera inspection technologies, and participate in the ongoing legal
and regulatory proceedings and investigations involving the San Bruno accident and natural gas pipeline matters;
• the results of the CPUC’s independent audit being conducted on the costs incurred by the Utility since 1996 on its natural gas transmission
pipelines;
• the outcome of the CPUC’s investigation of the December 24, 2008 natural gas explosion in Rancho Cordova;
• whether the Utility incurs civil or criminal penalties as a result of the pending or future proceedings and investigations related to the Utility’s
operations;
• changes in estimated third-party liability claims or insurance recoveries related to the San Bruno accident;
• the costs to comply with new state or federal requirements applicable to natural gas transmission pipelines and whether
the Utility is able to recover such costs through rates;
• whether the Utility incurs additional third-party liabilities or other costs in connection with service disruptions that may
occur as the Utility decreases or increases pressure in its natural gas transmission system to comply with regulatory
orders; and
• other factors and risks discussed in PG&E Corporation and the Utility’s 2010 Annual Report on Form 10-K and other
reports filed with the Securities and Exchange Commission.
