As of December 31, 2015, a valuation allowance for deferred tax assets of approximately $127.1 million was provided on the total deferred tax assets in certain jurisdictions. The valuation allowance is primarily related to numerous branches and legal entities for which there is no history of earnings in recent years. Further there is a partial valuation allowance on RGA Reinsurance Company of South Africa, Limited ("RGA South Africa"), RGA Reinsurance Company of Australia Limited (“RGA Australia”) and Aurora National net operating losses, RGA International Reinsurance Company Limited’s ("RGA International") foreign tax credit and RGA's deferred tax asset related to share expense for foreign entities. As of December 31, 2014, a valuation allowance for deferred tax assets of approximately $112.0 million was provided on the total deferred tax assets. The valuation allowance is primarily related to numerous branches and legal entities for which there is no history of earnings in recent years. Further there is a partial valuation allowance on RGA South Africa and RGA Australia's net operating losses, RGA International's foreign tax credit and on RGA's deferred tax asset related to share expense for foreign entities. The Company utilizes valuation allowances when it believes, based on the weight of the available evidence, that it is more likely than not that the deferred income tax asset will not be utilized. The earnings of substantially all of the Company’s foreign subsidiaries have been permanently reinvested in foreign operations. A provision of $4.2 million has been made for U.S. taxes on repatriation. No other provision has been made for U.S. tax or foreign withholding taxes that may be applicable upon any repatriation or sale. The determination of the unrecognized deferred tax liability for temporary differences related to investments in the Company’s foreign subsidiaries is not practicable. At December 31, 2015 and 2014, the financial reporting basis in excess of the tax basis for which no deferred taxes have been recognized was approximately $992.9 million and $1,115.2 million, respectively. During 2015, 2014 and 2013, the Company received federal and foreign income tax refunds of approximately $136.8 million, $9.3 million and $2.6 million, respectively. The Company made cash income tax payments of approximately $178.4 million, $79.6 million and $113.4 million in 2015, 2014 and 2013, respectively. At December 31, 2015 and 2014, the Company recognized gross deferred tax assets associated with net operating losses of approximately $1,771.0 million and $647.0 million, respectively. The earliest expiration for net operating losses that do not have a valuation allowance is 2025, during which $10.5 million of net operating losses would expire if not utilized. The remaining net operating losses have either a valuation allowance or indefinite carryforward periods. However, these net operating losses, other than the net operating losses for which there is a valuation allowance, are expected to be utilized in the normal course of business during the period allowed for carryforwards and in any event, are not expected to be lost, due to the application of tax planning strategies that the Company would utilize. The Company files income tax returns in the U.S. federal jurisdiction and various state and foreign jurisdictions. The Company is under continuous examination by the Internal Revenue Service and is subject to audit by taxing authorities in other foreign jurisdictions in which the Company has significant business operations. The income tax years under examination vary by jurisdiction. The Company is no longer subject to U.S. federal income tax examinations by tax authorities for years prior to 2011 and with a few exceptions, the Company is no longer subject to state and foreign income tax examinations by tax authorities for years prior to 2010. As of December 31, 2015, the Company’s total amount of unrecognized tax benefits was $296.2 million and the total amount of unrecognized tax benefits that would affect the effective tax rate, if recognized, was $30.6 million. Management believes there will be no material impact to the Company’s effective tax rate related to unrecognized tax benefits over the next 12 months. A reconciliation of the beginning and ending amount of unrecognized tax benefits for the years ended December 31, 2015, 2014 and 2013, is as follows (dollars in thousands):
|  | Total Unrecognized Tax Benefits
|  | 2015 |  | 2014 |  | 2013
Beginning balance, January 1 |  | $ | 274,661 |  |  | $ | 279,801 |  |  | $ | 245,636 |

Ending balance, December 31 |  | $ | 296,213 |  |  | $ | 274,661 |  |  | $ | 279,801 |
The Company recognized interest expense (benefit) associated with uncertain tax positions in 2015, 2014 and 2013 of $8.2 million, $(36.6) million and $7.6 million, respectively. As of December 31, 2015 and 2014, the Company had $28.8 million and $20.7 million, respectively, of accrued interest related to unrecognized tax benefits.
