Beginning with the date benefits are realized, other intangible assets are generally amortized using the straight-line method over their estimated period of benefit of three to 30 years. Amortization expense of $17 million, $16 million and $18 million was recognized during fiscal 2013, 2012 and 2011, respectively. We estimate amortization expense on intangible assets for the next five fiscal years subsequent to September 28, 2013, will be: 2014 - $18 million; 2015 - $18 million; 2016 - $17 million; 2017 - $14 million; 2018 - $13 million.
