Note 5.

Income Taxes

As of March 29, 2015, the Company had approximately $5.1 million of total unrecognized income tax benefits. Included in this amount were a total of $2.6 million of unrecognized income tax benefits that, if recognized, would affect the Company’s effective tax rate. While it is expected that the amount of unrecognized tax benefits will change in the next 12 months, the Company does not expect the change to have a significant impact on the results of operations or the financial position of the Company.

The Company’s accounting policy is to recognize interest and penalties accrued relating to unrecognized income tax benefits as part of its provision for income taxes. The Company had a net increase of approximately $0.1 million during the three months ended March 29, 2015, and had an accrued balance of $1.4 million of interest and penalties as of March 29, 2015.

The Company operates in multiple taxing jurisdictions, both within and outside the U.S. In certain situations, a taxing authority may challenge positions that the Company has adopted in its income tax filings. The Company, with a few exceptions (none of which are material), is no longer subject to income tax examinations by tax authorities for years prior to 2007.

Provision for taxes was $12.1 million as compared to $7.0 million in the prior year. The effective tax rate was 25.4% as compared to 30.0% in prior year. The lower effective tax rate was primarily due to a change in the mix of earnings, tax benefits on one-time charges at a higher rate, and higher depletion deductions.
