At December 31, 2016 and 2015, we had $251.2 million and $218.7 million, respectively, of gross deferred tax assets related to U.S. alternative minimum tax credits that can be carried forward indefinitely. We had gross domestic (including states) and foreign net operating loss carryforwards, inclusive of discontinued operations, of $3.7 billion and $6.9 billion, respectively, at December 31, 2016. We had gross domestic and foreign net operating loss carryforwards at December 31, 2015 of $3.9 billion and $11.1 billion, respectively. The U.S. Federal net operating losses will begin to expire in 2035 and state net operating losses will begin to expire in 2019. The foreign net operating losses can be carried forward indefinitely. We had foreign tax credit carryforwards of $5.8 million at December 31, 2016 and December 31, 2015. The foreign tax credit carryforwards will begin to expire in 2020. Additionally, there is a net operating loss carryforward, inclusive of discontinued operations, of $1.4 billion for Alternative Minimum Tax. No benefit has been recorded in the financials for this attribute as ASC 740, Income Taxes, does not allow for the recording of deferred taxes under alternative taxing systems. We recorded a $37.7 million net decrease in the valuation allowance of certain deferred tax assets. Of this amount, a $149.1 million decrease was due to the change in the Luxembourg statutory rate and a $33.1 million decrease resulted from prior year adjustments due to a change in estimate of the 2015 net operating loss. Offsetting increases to the valuation allowance included a $104.9 million increase related to the recording of deferred tax assets due to current year operating activities and a $39.6 million increase related to the close of audits. At December 31, 2016 and 2015, we had no cumulative undistributed earnings of foreign subsidiaries included in consolidated retained earnings. Accordingly, no provision has been made for U.S. deferred taxes related to future repatriation of earnings. A reconciliation of the beginning and ending amount of unrecognized tax benefits is as follows:
|  | (In Millions)
|  | 2016 |  | 2015 |  | 2014
Unrecognized tax benefits balance as of January 1 |  | $ | 156.2 |  |  | $ | 72.6 |  |  | $ | 71.8 |
Increases/(decreases) for tax positions in prior years |  | (61.0 | ) |  | 6.7 |  |  | — |
Increases for tax positions in current year |  | 0.2 |  |  | 78.5 |  |  | 5.9 |
Decrease due to foreign exchange |  | — |  |  | — |  |  | (0.2 | )
Settlements |  | (64.7 | ) |  | (1.1 | ) |  | — |
Lapses in statutes of limitations |  | — |  |  | (0.5 | ) |  | (3.7 | )
Other |  | — |  |  | — |  |  | (1.2 | )
Unrecognized tax benefits balance as of December 31 |  | $ | 30.7 |  |  | $ | 156.2 |  |  | $ | 72.6 |
At December 31, 2016 and 2015, we had $30.7 million and $156.2 million, respectively, of unrecognized tax benefits recorded. Of this amount, $8.3 million and $21.5 million, respectively, were recorded in Other liabilities and $22.4 million and $134.7 million, respectively, were recorded as Other non-current assets in the Statements of Consolidated Financial Position for both years. If the $30.7 million were recognized, only $8.3 million would impact the effective tax rate. We do not expect that the amount of unrecognized benefits will change significantly within the next 12 months. At December 31, 2016 and 2015, we had $0.8 million and $2.1 million, respectively, of accrued interest and penalties related to the unrecognized tax benefits recorded in Other liabilities in the Statements of Consolidated Financial Position. Tax years 2012 and forward remain subject to examination for the U.S. and Australia. Tax years 2008 and forward remain subject to examination for Canada.
