1. Basis of Presentation

Alpha and Omega Semiconductor Limited is the parent company of all Alpha and Omega Semiconductor subsidiaries. It was incorporated in Bermuda on September 27, 2000 as an exempted limited liability company. The address of its registered office is Clarendon House, 2 Church Street, Hamilton HM 11, Bermuda.

The accompanying condensed parent company financial statements have been prepared in accordance with Rule 12-04, Schedule I of Regulation S-X, as the restricted net assets of its subsidiaries exceed 25% of the consolidated net assets of Alpha and Omega Semiconductor Limited and its subsidiaries (the “Company”).

The parent company records its investment in subsidiaries under the equity method of accounting. Such investment is presented on the balance sheet as "Investment in subsidiaries" and the subsidiaries' net income (loss) are recognized based on the effective shareholding percentage as income on equity investment in subsidiaries on the statement of operations. Intercompany balances and transactions have not been eliminated. The revenue recorded represents intercompany administrative service fees charged by the parent company starting in fiscal year 2013.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted. The footnote disclosures contain supplemental information relating to the operations of the Company and, as such, these statements should be read in conjunction with the notes to the consolidated financial statements of the Company.
