7. Income Taxes

During the first quarter of 2012 and in connection with the sale of its six remaining Company-owned stores in a certain market to a franchisee, the Company recorded a deferred tax asset related to the capital loss that resulted from the write-off of the tax basis goodwill associated with the sold market. Management believes it is more likely than not that a portion of the deferred tax asset will not be realized and provided a valuation allowance of approximately $0.9 million. The valuation allowance was recorded as an increase to the provision for income taxes and increased the Company's effective tax rate in the first quarter of 2012. On an ongoing basis, management will assess whether it remains more likely than not that the net deferred tax asset will be realized.

During the first quarter of 2011, the Company reduced its liability for unrecognized tax benefits related to a state income tax matter by approximately $0.5 million. Approximately $0.3 million of the decrease was related to gross unrecognized tax benefits and approximately $0.2 million was related to interest and penalties. As a result, approximately $0.2 million was recognized as an income tax benefit and reduced the Company's effective tax rate in the first quarter of 2011.
