Note 10 — Income Taxes

Our consolidated effective tax rate was 38% and 36% as applied to income (loss) before income taxes and earnings (losses) from unconsolidated entities for the first quarter of fiscal years 2013 and 2012, respectively. In determining the quarterly provision for income taxes, we use an estimated annual effective tax rate based on forecasted annual pre-tax income and permanent items, statutory tax rates and tax planning opportunities in the various jurisdictions in which we operate.

The impact of significant discrete items is separately recognized in the quarter in which they occur. We recognize foreign currency gains and losses on the Japanese Yen-denominated Westinghouse Bonds as discrete items in each reporting period due to their volatility and the difficulty in estimating such gains and losses reliably.

We expect the fiscal year 2013 annual effective tax rate, excluding discrete items, applicable to forecasted income before income taxes and earnings (losses) from unconsolidated entities to be approximately 37%. Significant factors that could impact the annual effective tax rate include management’s assessment of certain tax matters, the location and amount of our taxable earnings, changes in certain non-deductible expenses and expected credits.

Under ASC 740-10, we provide for uncertain tax positions, and the related interest, and adjust unrecognized tax benefits and accrued interest accordingly. We recognize potential interest and penalties related to unrecognized tax benefits in income tax expense.

As of November 30, 2012, our unrecognized tax benefits were $6.5 million, of which $6.5 million would, if recognized, affect our effective tax rate.

We file income tax returns in numerous tax jurisdictions, including the U.S., most U.S. states and certain non-U.S. jurisdictions including jurisdictions where our subsidiaries execute project-related work. The statute of limitations varies by the various jurisdictions in which we operate. With few exceptions, we are no longer subject to U.S. state and local or non-U.S. income tax examinations by tax authorities for years before fiscal year 2004 and US Federal examinations for years before fiscal 2009. Although we believe our calculations for our tax returns are correct and the positions taken thereon are reasonable, the final outcome of tax audits could be materially different than the resolution we currently anticipate, and those differences could result in significant costs or benefits to us.

The IRS is now in the process of conducting audits of fiscal year 2011 under a limited focused examination and fiscal year 2012 under its Compliance Assurance Process (CAP). Under CAP, the IRS works with large business taxpayers on a contemporaneous, real-time basis to resolve issues prior to the filing of tax returns which allows participants to remain current with IRS examinations.

We do not believe there will be significant changes in our unrecognized tax benefits within the next 12 months.
