Deferred income tax assets or liabilities are established for temporary differences between the financial reporting amounts and tax bases of assets and liabilities that will result in deductible or taxable amounts, respectively, in future years. The tax effects of temporary differences that give rise to the deferred tax assets and liabilities at December 31, 2012 and 2011, are as follows:
| December 31,
| 2012 |  | 2011

Convertible senior notes | (6,665 | ) |  | (10,917 | )

Net deferred income tax (liability) asset | $ | (49,303 | ) |  | $ | 21,981 |
The total deferred income tax asset includes other than temporary impairments on investments. The other than temporary impairments will not be available for utilization for tax purposes until the securities are either sold at a loss or deemed completely worthless. The other than temporary impairments totaled $23.4 million and $26.0 million as of December 31, 2012 and 2011, respectively. Included in the deferred income taxes is the expected income tax benefit attributable to unrealized losses on available for sale fixed maturity securities. There is no valuation allowance provided for the deferred income tax asset attributable to unrealized losses on available for sale fixed maturity securities. Management expects that the passage of time will result in the reversal of these unrealized losses due to the fair value increasing as these securities near maturity. Management has the intent and ability to hold these securities to maturity because we generate adequate cash flow from new business to fund all foreseeable cash flow needs and do not believe it would ever be necessary to liquidate these securities at a loss to meet cash flow needs. For deferred income taxes related to unrealized losses on equity securities, we had sufficient future taxable income from capital gain sources to support the realizability of the deferred income tax asset. Realization of our deferred income tax assets is more likely than not based on expectations as to our future taxable income and considering all other available evidence, both positive and negative. Therefore, no valuation allowance against deferred income tax assets has been established as of December 31, 2012 and 2011. There were no material income tax contingencies requiring recognition in our consolidated financial statements as of December 31, 2012. We are no longer subject to income tax examinations by tax authorities for years prior to 2008. At December 31, 2012, we had non-life net operating loss carryforwards for federal income tax purposes totaling $23.4 million which expire beginning in 2018 through 2032.
