The provision for income taxes increased by $0.5 million during the twelve months ended December 31, 2014 as a result of an increase in foreign income taxes and state income taxes computed without the benefit of stock options.

The following table presents a reconciliation of the statutory federal rate and our effective tax rate:

At December 31, 2014, we had federal net operating loss carryforwards of approximately $447.0 million and tax credit carryforwards of approximately $7.9 million. If realized, approximately $378.0 million of the net operating loss carryforwards will be recognized as a benefit through additional paid in capital. The federal net operating losses and tax credits expire in years beginning in 2021. At December 31, 2014, we had state net operating loss carryforwards of approximately $496.0 million which expire in years beginning in 2015. In addition, we had state tax credit carryforwards of approximately $8.3 million that do not expire and approximately $3.7 million of credits that will expire beginning in 2024.

Under Section 382 and 383 of the Internal Revenue Code of 1986, as amended, or the Code, if a corporation undergoes an "ownership change," the corporation's ability to use its pre-change net operating loss carryforwards and other pre-change tax attributes, such as research tax credits, to offset its post-change income may be limited. In general, an "ownership change" will occur if there is a cumulative change in our ownership by "5-percent shareholders" that exceeds 50 percentage points over a rolling three-year period. Similar rules may apply under state tax laws. Utilization of our net operating loss and tax credit carryforwards may be subject to annual limitations due to ownership changes. Such annual limitations could result in the expiration of our net operating loss and tax credit carryforwards before they are utilized.

During the twelve months ended December 31, 2014, our valuation allowance increased by $16.2 million. At December 31, 2013 and 2014, we maintained a full valuation allowance on our net deferred tax assets. The valuation allowance was determined in accordance with the provisions of Accounting Standards Codification 740 - Income Taxes, which requires an assessment of both positive and negative evidence when determining whether it is more likely than not that deferred tax assets are recoverable. Such assessment is required on a jurisdiction by jurisdiction basis. Our history of cumulative losses, along with expected future U.S. losses required that a full valuation allowance be recorded against all net deferred tax assets. We intend to maintain a full valuation allowance on net deferred tax assets until sufficient positive evidence exists to support reversal of the valuation allowance.

At December 31, 2013 and 2014 we have unrecognized tax benefits of approximately $5.2 million and $5.8 million. The increase in our unrecognized tax benefits was primarily attributable to current year activities. A reconciliation of the beginning and ending amounts of unrecognized tax benefits (excluding interest and penalties) is as follows:

The total unrecognized tax benefits, if recognized, would not affect our effective tax rate as the tax benefit would increase a deferred tax asset, which is currently offset with a full valuation allowance. We do not anticipate that the amount of existing unrecognized tax benefits will significantly increase or decrease within the next twelve months. Accrued interest and penalties related to unrecognized tax benefits are recorded in the provision for income taxes. We did not have such interest, penalties or tax benefits during the twelve months ended January 31, 2013, the eleven months ended December 31, 2013 or the twelve months ended December 31, 2014.

We file income tax returns in the United States, California, other states and international jurisdictions. Tax years 2000 to 2014 remain subject to examination for U.S. federal, state and international purposes. All net operating losses and tax credits generated to date are subject to adjustment for U.S. federal and state purposes. We are not currently under examination in any federal, state or international jurisdictions.
