Explanatory Note

UGI Corporation (the “Company”) is filing this Current Report on Form 8-K as a result of discussions with the Securities and Exchange Commission (“SEC”) Staff regarding the applicable calculation and interpretation of the purchase price test, which is one of the three significance tests in Rule 1-02(w) of Regulation S-X. Effective January 12, 2012, the Company’s consolidated, less than majority-owned subsidiary, AmeriGas Partners, L.P. (“AmeriGas”), a publicly-held limited partnership engaged in the retail propane distribution business, acquired Heritage Operating, L.P. and its general partner and subsidiaries and Titan Energy Partners, L.P. and its general partner and subsidiaries (collectively, “Heritage Propane”), the subsidiaries of Energy Transfer Partners, L.P. (“ETP”) that operated ETP’s propane operations. The consideration that AmeriGas paid for Heritage Propane was $1.47 billion in cash (after adjustments for working capital, cash, the amount of indebtedness of Heritage Propane outstanding and certain excess sales proceeds resulting from ETP’s sale of Heritage Propane’s former cylinder exchange business) and the issuance of 29,567,362 common units of AmeriGas with a fair value of approximately $1.1 billion as of the date of the acquisition. AmeriGas reported this acquisition on a Current Report on Form 8-K dated January 12, 2012 and filed required historical financial statements of Heritage Propane and pro forma financial information on a timely basis. As a result of AmeriGas’s acquisition, the Company’s ownership interest in AmeriGas decreased from 44% to 29%. Heritage Propane was not significant to the Company under either the asset test in Rule 1-02(w)(2), which required a comparison of the Company’s proportionate share in Heritage Propane to the Company’s total assets, or the pre-tax income test in Rule 1-02(w)(3), which required a comparison of the income from continuing operations before income taxes, extraordinary items and cumulative effect of a change in accounting principle of Heritage Propane, excluding non-controlling interests, to the Company’s comparable income excluding non-controlling interests. In its calculation under the purchase price test, the Company made adjustments to account for the Company’s ownership interest in AmeriGas. The SEC Staff disagreed with the Company’s adjustment to take into account its actual ownership interest in AmeriGas and concluded that the purchase price test must be calculated as a comparison of 100% of the purchase price paid by AmeriGas, as calculated under generally accepted accounting principles in the United States, to the Company’s total assets, notwithstanding the Company’s 44% interest in AmeriGas prior to its acquisition of Heritage Propane and the Company’s 29% interest in AmeriGas after the acquisition. Based on the SEC Staff’s calculation method with respect to the purchase price test, Heritage Propane was significant to the Company under the purchase price test at a level that requires the filing of two years of financial statements. The Company is filing this Current Report on Form 8-K as a result of the SEC Staff’s views.

The explanatory note set forth above is incorporated into Item 2.01 by reference.
