On March 22, 2013, Quicksilver Resources Inc. (the "Company") issued a press release announcing that the Company has filed its 2012 Form 10-K. A copy of the press release is attached as Exhibit 99.1 and is incorporated herein by reference. The information contained in this Item 2.02, including Exhibit 99.1 attached hereto, is being furnished to the Securities and Exchange Commission and shall not be deemed "filed" for the purpose of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that Section.
The press release contains a non-GAAP financial measure within the meaning of Regulation G promulgated by the Securities and Exchange Commission. We presented adjusted net income for all periods presented in the press release to exclude the effect on net income of certain revenue, expense, gain and loss associated with items not typically included in published estimates, in order to enhance the user's overall understanding of our current financial performance. As part of the press release, we provided a reconciliation of adjusted net income to net income, which is the most comparable financial measure determined in accordance with accounting principles generally accepted in the United States of America ("GAAP"). Our management believes this non-GAAP measure provides useful information to both management and investors by excluding certain revenues and expenses that may not be indicative of our core operating results, and will enhance the ability of management and investors to compare our results of operations from period to period.
