Interim Financial Statements

The accompanying condensed consolidated financial statements as of October 2, 2011 and for the three and nine months ended October 2, 2011 and October 3, 2010 were unaudited and are presented in accordance with the requirements for quarterly reports on Form 10-Q and, consequently, do not include all of the information and footnote disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). In the opinion of management, the Company's consolidated condensed financial statements include all adjustments (consisting solely of normal recurring adjustments) necessary for the fair statement of its financial information included herein in accordance with GAAP and the rules and regulations of the United States Securities and Exchange Commission (the "SEC").

Use Of Estimates And Assumptions

Use of Estimates and Assumptions

The preparation of these unaudited condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amount of our assets and liabilities, the disclosures of our contingent assets and liabilities as of the date of our consolidated financial statements, and the reported amount of revenue and expenses during the period. Actual results could differ from those estimates. Consolidated results of operations for interim periods are not necessarily indicative of results for the full year. Our unaudited condensed consolidated financial statements should be read in conjunction with our consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended January 2, 2011, filed with the SEC on February 24, 2011.

Change In Accounting Estimate And Capitalization Thresholds

Change in Accounting Estimate and Capitalization Thresholds

During 2011, we performed an assessment of the useful lives of all of our property and equipment. In evaluating the useful lives, we considered the historical life of the assets, operational strategy, and related functionality. We concluded that certain games and leasehold improvements in our stores remained in service longer than the depreciable life assigned and certain pieces of equipment utilized in our stores remained in service for less than the depreciable life assigned. As a result, effective July 4, 2011 we revised the estimate of the useful lives of certain (i) games from six years to either eight or 10 years, (ii) leasehold improvements related to expansions of our stores from 15 years to 20 years or the remaining lease term, if shorter, (iii) leasehold improvements related to major remodels of our stores from 10 years to 15 years or the remaining lease term, if shorter, and (iv) other equipment utilized in our stores had various useful lives reduced. Accounting guidance requires a change in estimate to be accounted for on a prospective basis, by amortizing an assets' current carrying value over its revised remaining useful life. The net impact of this change in estimate benefited depreciation and amortization expense for both the three and nine months ended October 2, 2011, by approximately $1.1 million. In addition, we expect this change in accounting estimate to impact depreciation and amortization expense in the fourth quarter of 2011 by approximately $1.8 million. We also expect this change in estimated useful lives to favorably benefit our depreciation and amortization expense for the assets impacted as of July 4, 2011, during fiscal 2012, 2013 and 2014 by approximately $6.0 million, $3.7 million, and $1.6 million, respectively.

In conjunction with the revision of the estimated useful lives of certain property and equipment, we also changed our capitalization thresholds with respect to costs associated with certain refurbishment of games, as well as costs related to the replacement of certain asset parts. The impact of this change unfavorably impacted other store operating costs for both the three and nine months ended October 2, 2011 by approximately $0.4 million. We expect this change to unfavorably impact other store operating costs in the fourth quarter of 2011 by approximately $0.4 million and expect this change to unfavorably impact fiscal 2012 by approximately $1.4 to $1.6 million.

We estimate that the effect of both the change in estimate and the change in capitalization thresholds benefited our fully diluted earnings per share by approximately $0.02 per share for both the three months and nine months ended October 2, 2011, respectively.
