In June 2012, Amkor Technology, Inc. ("ATI") amended and restated the $100.0 million senior secured revolving credit facility to increase the facility amount to $150.0 million and extend its term by two years to June 2017. The facility has a letter of credit sub-limit of $25.0 million. As amended, interest is charged under the facility at a floating rate based on the base rate in effect from time to time plus the applicable margins which range from 0.25% to 1.00% for base rate revolving loans, or LIBOR plus 1.5% to 2.25% for LIBOR revolving loans. In connection with amending and extending the facility, ATI capitalized $0.8 million of deferred debt issuance costs for the nine months ended September 30, 2012.

In September 2012, ATI issued $300.0 million of 6.375% Senior Notes due October 2022 (the “2022 Notes”). The 2022 Notes were issued at par and are senior unsecured obligations. Interest is payable semi-annually on April 1 and October 1 of each year, commencing on April 1, 2013. In addition, we entered into a Registration Rights Agreement with the initial purchasers of the 2022 Notes for freely tradable notes issued by us. If we are unable to effect the exchange offer within 240 days of the issuance of the 2022 Notes, we have agreed to pay additional interest on the notes up to 0.5%. We used $224.9 million of the net proceeds from the issuance of the 2022 Notes to repay subsidiary debt of which $67.8 million was paid prior to September 30, 2012 and $157.1 million was paid in October 2012. We incurred $5.2 million of debt issuance costs associated with the 2022 Notes. In October 2012, we repaid the term loans due 2014 and 2016 and recorded a $1.2 million loss on extinguishment related to prepayment fees of $0.5 million and a charge for the write-off of associated unamortized deferred debt issuance costs of $0.7 million.

In June 2012, Amkor Technology Korea, Inc., a Korean subsidiary (“ATK”) entered into a $41.0 million revolving credit facility with a Korean Bank with a term of 12 months. The loan bears interest at the foreign currency funding-linked base rate plus 2.33% (4.49% as of September 30, 2012). Principal is payable upon maturity and interest is paid monthly. The loan is collateralized with certain land, buildings and equipment at our ATK facilities.

In March 2012, ATK repaid the remaining outstanding balance of the ATK term loan due May 2013 by entering into a $100.0 million term loan with the same Korean bank, which is due upon maturity in March 2015. The term loan bears interest at a foreign currency funding-linked base rate plus 2.30% (4.58% as of September 30, 2012) to be paid monthly. The term loan is collateralized by substantially all the land, factories and equipment located at our ATK facilities.

In June 2012, ATK entered into a $150.0 million, five-year secured term loan with a Korean bank which is collateralized by substantially all the land, factories and equipment located at our ATK facilities. Interest is paid quarterly, $50.0 million at LIBOR plus 3.90% (4.36% as of September 30, 2012) ("Tranche A") and $100.0 million at LIBOR plus 3.94% (4.38% as of September 30, 2012) ("Tranche B"). As of September 30, 2012, ATK borrowed $50.0 million from Tranche A and $25.0 million from Tranche B. The proceeds of Tranche A were used to fully repay the ATK term loan due July 2014. In October 2012, an additional $20.0 million was borrowed from Tranche B. The remaining $55.0 million available under Tranche B can be borrowed through June 2013 to fund capital additions. The term loan is due in full upon maturity in July 2017.

In January 2012, Amkor Technology Taiwan Ltd, a Taiwanese subsidiary, converted the existing NT$1.5 billion term loan from a Taiwanese to a U.S. dollar denominated term loan. The term loan previously bore interest at the 90-day primary commercial paper rate plus 0.835% and now bears interest at the Taipei Foreign Exchange ("TAIFX") six month U.S. dollar rate plus a bank-determined spread (2.54% as of September 30, 2012). In September 2012, as noted above at (2), the term loan was paid off in full. In addition, the term loan was converted to a revolving credit facility. All other terms and conditions remain the same. At conversion, availability under the revolving credit facility was $44.0 million and subsequent availability steps down $5.0 million every six months from the original available balance, with a balloon payment of the remaining balance at maturity. As of September 30, 2012, $44.0 million was available to be drawn.
