(1) | At August 26, 2017, Other includes $46,000 related to state NOLs that will begin to expire in Fiscal 2021. We have evaluated all the positive and negative evidence and consider it more likely than not that these carryforwards can be realized.
Unrecognized Tax Benefits Changes in the unrecognized tax benefits are as follows:
(In thousands) |  | August 26, 2017 |  | August 27, 2016 |  | August 29, 2015
Unrecognized tax benefits - beginning balance |  | $ | 1,710 |  |  | $ | 1,589 |  |  | $ | 1,709 |
Gross decreases - tax positions in a prior period |  | (536 | ) |  | (355 | ) |  | (568 | )
Gross increases - current period tax positions |  | 21 |  |  | 476 |  |  | 448 |
Unrecognized tax benefits - ending balance |  | 1,195 |  |  | 1,710 |  |  | 1,589 |
Accrued interest and penalties |  | 411 |  |  | 751 |  |  | 922 |
Total unrecognized tax benefits |  | $ | 1,606 |  |  | $ | 2,461 |  |  | $ | 2,511 |
The amount of unrecognized tax benefits is not expected to change materially within the next 12 months. If the remaining uncertain tax positions are ultimately resolved favorably, $1.5 million of unrecognized tax benefits would have a favorable impact on our effective tax rate. It is our policy to recognize interest and penalties accrued relative to unrecognized tax benefits into tax expense. We file a US federal tax return and various state tax returns. Although certain years are no longer subject to examinations by the various taxing authorities, NOL carryforwards generated in those years may be adjusted upon examination by the taxing authorities if the NOL carryforwards are utilized in a future period. As of August 26, 2017, our federal returns from Fiscal 2014 to present are subject to review by the IRS. With limited exception, state returns from Fiscal 2013 to present continue to be subject to review by state taxing jurisdictions. Several years may lapse before an uncertain tax position is audited and finally resolved and it is difficult to predict the outcome of such audits.
