PE is no longer obligated to file such annual or quarterly reports due to the redemption of its preferred stock on June 30, 2011 as we discuss in Note 5. We describe our significant accounting policies in Note 1 of the Notes to Consolidated Financial Statements in the Annual Report. We follow the same accounting policies for interim reporting purposes, except for the adoption of new accounting standards as we discuss in Note 2. The Sempra Utilities and Sempra Pipelines & Storage's Mobile Gas and Ecogas prepare their financial statements in accordance with GAAP provisions governing regulated operations, as we discuss in Note 1 of the Notes to Consolidated Financial Statements in the Annual Report.
