Income Taxes	INCOME TAXES The Company calculates its interim income tax provision by estimating the annual effective tax rate and applying that rate to its year-to-date ordinary earnings. The tax expense or benefit related to significant, unusual or extraordinary items that will be separately reported or reported net of their related tax effect are individually computed and recognized in the interim period in which those items occur.

The Company's effective income tax rate for the 13-week period ended September 28, 2013 was 51.3%, which resulted in a provision of $6.7 million, while the effective tax rate for the 13-week period ended September 29, 2012 was 39.4%, which also resulted in a provision of $6.7 million. The Company's effective income tax rate for the 39-week period ended September 28, 2013 was 44.8%, which resulted in a provision of $16.0 million, while the effective tax rate for the 39-week period ended September 29, 2012 was 40.0%, which resulted in a provision of $17.7 million. On July 11, 2013, the Governor of California signed legislation which significantly changed the California Enterprise Zones ("CA EZ"), effective for tax years beginning on or after January 1, 2014. Under prior law, CA EZ credits did not expire. Under the newly-enacted law, credits expire after 10 years. The Company currently has a $4.3 million deferred tax asset for California tax credits, which amount does not include the portion of the deferred tax asset that is already offset by an unrecognized tax benefit. In evaluating the impact of the new tax law, the Company determined that it is more likely than not that the Company will not be able to realize the tax benefit for a portion of the CA EZ credits.

After adjusting for the expected federal tax benefit, the net valuation allowance recorded was $1.5 million.
