[1] | On February 4, 2013, we converted from a limited liability company to a corporation. In addition, we elected to be treated as a corporation for federal and state income tax purposes effective as of January 1, 2013. Therefore, we have been subject to federal and state income tax expense since January 1, 2013. For tax purposes, our conversion from a limited liability company to a corporation was deemed a nontaxable transfer of Boise Cascade, L.L.C., assets and liabilities to Boise Cascade Company. As a result of our conversion to a corporation in February 2013, we recorded net deferred tax assets of $68.7 million, the effect of which was recorded as an income tax benefit in our Consolidated Statement of Operations for the year ended December 31, 2013.
[2] | The decrease primarily relates to the tax effect of changes in recorded pension liabilities. See Note 7, Retirement and Benefit Plans, for more information.
[3] | We have an investment in foreign subsidiaries, which at December 31, 2015 and 2014, had $9.9 million and $15.8 million, respectively, of deferred tax assets. Deferred tax assets are reduced by a valuation allowance when it is more likely than not that some portion of the deferred tax assets will not be realized. The foreign deferred tax assets results primarily from net operating losses and were fully offset by a valuation allowance. The net operating losses will expire beginning in 2026 through 2033.
