Income Taxes	12. Income Taxes At the end of each interim reporting period, the Company determines its estimated annual effective tax rate, which is revised, as required, at the end of each successive interim period based on facts known at that time. The estimated annual effective tax rate is applied to the year-to-date pre-tax income at the end of each interim period. The tax effect of significant unusual items is reflected in the period in which they occur. Since the Company is incorporated in Canada, it is required to use Canada’s statutory tax rate of 25.0% in the determination of the estimated annual effective tax rate. The Company’s reported effective tax rate on income from continuing operations of 12.1% and 13.3% for the three and six months ended June 29, 2012, respectively, differs from the expected Canadian federal statutory rate of 25.0% primarily due to the release of a portion of the Company’s valuation allowance, the income earned in jurisdictions with varying tax rates, and an increase in the Company’s liability for uncertain tax positions. The Company maintains a valuation allowance on its deferred tax assets in certain jurisdictions. A valuation allowance is required when, based upon an assessment of various factors including recent operating loss history, anticipated future earnings, and prudent and reasonable tax planning strategies, it is more likely than not that some portion of the deferred tax assets will not be realized. In conjunction with the Company’s ongoing review of its actual results and anticipated future earnings, the Company continuously reassesses the possibility of releasing the remaining valuation allowance currently in place on its deferred tax assets. It is reasonably possible that a significant portion of the valuation allowance will be released within the next twelve months. Such a release will be reported as a reduction to income tax expense without any impact on cash flows in the quarter in which it is released.
