(13) Income Taxes

Our effective tax rate was 20.0% for the six months ended January 31, 2012, which includes a net discrete tax benefit of $3,463,000 principally relating to the effective settlement of certain federal and state income tax audits and the reversal of previously recorded tax liabilities no longer required due to the expiration of applicable statutes of limitations. Excluding the impact of discrete tax items, our fiscal 2012 estimated tax rate is expected to approximate 35.0%. Our effective tax rate during fiscal 2012 only includes five months of benefit associated with the federal research and experimentation credit which expired on December 31, 2011.

At January 31, 2012 and July 31, 2011, total unrecognized tax benefits, excluding interest, were $3,454,000 and $6,763,000, respectively. Of these amounts, $2,791,000 and $5,719,000, respectively, net of the reversal of the federal benefit recognized as a deferred tax asset relating to state reserves, would positively impact our effective tax rate, if recognized. Unrecognized tax benefits result from income tax positions taken or expected to be taken on our income tax returns for which a tax benefit has not been recorded in our financial statements. Of the total unrecognized tax benefits, $3,235,000 and $3,811,000, including interest, were recorded as non-current income taxes payable in our Condensed Consolidated Balance Sheets at January 31, 2012 and July 31, 2011, respectively.

Our policy is to recognize interest and penalties relating to uncertain tax positions in income tax expense. At January 31, 2012 and July 31, 2011, interest accrued relating to income taxes was $133,000 and $545,000, respectively, net of the related income tax benefit.

In August 2011, we reached an effective settlement with the IRS relating to its audit of our federal income tax returns for fiscal 2007, fiscal 2008 and fiscal 2009. Although adjustments relating to the settlement of our prior year completed audits were immaterial, a resulting tax assessment or settlement for other potential later periods, or for other tax jurisdictions, could have a material adverse effect on our consolidated results of operations and financial condition.
