Changes in the amounts of unrecognized tax benefits were as follows: We had gross unrecognized tax benefits of $20.6 million and $19.8 million as of December 31, 2019 and 2018, respectively. If the current gross unrecognized tax benefits were recognized, the result would be an increase in our income tax benefit of $20.7 million and $19.6 million, respectively. These amounts are net of accrued interest and penalties relating to unrecognized tax benefits of $0.4 million and $0.2 million, respectively. We believe that it is reasonably possible that $0.2 million of our currently remaining unrecognized tax benefits may be recognized by the end of 2020, as a result of a lapse of the applicable statute of limitations. <table> <tbody> <tr><td></td><td></td><td>Year Ended December 31,</td><td></td></tr> <tr><td>(In thousands)</td><td>2019</td><td>2018</td><td>2017</td></tr> <tr><td>Beginning balance as of January 1</td><td>$ 19,821</td><td>$ 10,939</td><td>$ 10,616</td></tr> <tr><td>Increases for tax positions related to the current year</td><td>1,240</td><td>8,977</td><td>640</td></tr> <tr><td>Decreases for tax positions related to prior years</td><td>0</td><td>0</td><td>(146)</td></tr> <tr><td>Increases for tax positions related to prior years</td><td>95</td><td>367</td><td>153</td></tr> <tr><td>Decreases relating to settlements with taxing authorities</td><td>0</td><td>0</td><td>0</td></tr> <tr><td>Increases acquired in business acquisitions</td><td>0</td><td>540</td><td>0</td></tr> <tr><td>Foreign currency translation</td><td>3</td><td>(5)</td><td>10</td></tr> <tr><td>Reductions due to lapsed statute of limitations</td><td>(555)</td><td>(997)</td><td>(334)</td></tr> <tr><td>Ending balance as of December 31</td><td>$ 20,604</td><td>$ 19,821</td><td>$ 10,939</td></tr> </tbody> </table>

Volatility in average selling prices for our semiconductor memory and storage products may adversely affect our business. We have experienced significant volatility in our average selling prices, including dramatic declines as noted in the table below, and may continue to experience such volatility in the future. In some prior periods, average selling prices for our products have been below our manufacturing costs and we may experience such circumstances in the future. Average selling prices for our products that decline faster than our costs could have a material adverse effect on our business, results of operations, or financial condition. <table> <tbody> <tr><td></td><td>DRAM</td><td>NAND</td></tr> <tr><td></td><td>(percentage change in average selling prices)</td><td></td></tr> <tr><td>2019 from 2018</td><td>(30)%</td><td>(44)%</td></tr> <tr><td>2018 from 2017</td><td>37%</td><td>(8)%</td></tr> <tr><td>2017 from 2016</td><td>19%</td><td>(7)%</td></tr> <tr><td>2016 from 2015</td><td>(35)%</td><td>(19)%</td></tr> <tr><td>2015 from 2014</td><td>(11)%</td><td>(15)%</td></tr> </tbody> </table>
