The decrease in amortization of intangible assets for the three and nine months
(8,243 ) (21.8 )%
The term loan facility was fully paid off in the fourth quarter of fiscal year 2012, which resulted in the decrease in interest expense for the three months ended
July 27, 2013, compared to the three months ended July 28, 2012. The decrease in interest expense is also partially due to the refinancing of the 6.625% senior secured notes due 2018 (the "2018 Notes"). In January 2013, we issued $300.0 millionin aggregate principal amount of 4.625% Senior Notes due 2023 (the "2023 Notes") in a private placement (the "Offering"). The proceeds from the Offering, together with cash on hand, were used on February 21, 2013, to redeem all of the outstanding 2018 Notes, which had a higher interest rate. The transactions are described further below in "Liquidity and Capital Resources." Interest expense increased for the nine months ended July 27, 2013, compared to the nine months ended July 28, 2012, primarily due to the $15.3 millionexpense that we recorded in the first quarter of fiscal year 2013, for the call premium, debt issuance costs and original issue discount relating to the 2018 Notes, in accordance with the applicable accounting guidance for debt modification and extinguishment, and for interest cost accounting, (additionally, see Note 8, "Borrowings," of the Notes to Condensed Consolidated Financial Statements).
