Revolving Line of Credit

KEMET Electronics Corporation (“KEC”) and KEMET Electronics Marketing (S) Pte Ltd. (“KEMET Singapore”) (each a “Borrower” and, collectively, the “Borrowers”) entered into a Loan and Security Agreement (the “Loan and Security Agreement”) which provides a $50.0 million revolving line of credit. A portion of the U.S. and Singapore facilities can be used to issue letters of credit (“Letters of Credit”). Pursuant to an amendment to the Loan and Security Agreement entered into on April 30, 2014, the facilities expire on December 31, 2015.

As of September 30, 2014 the Company had outstanding borrowings of $25.2 million under the revolving line of credit, of which $13.2 million was borrowed under the U.S. facility at a rate of 5.25% (Base Rate, as defined in the Loan and Security Agreement, plus 2.25%) with no specific repayment date (Base Rate borrowing can be repaid at any time prior to the expiration of the facility), and $12.0 million borrowed under the Singapore facility at a rate of 3.50% (London Interbank Offer Rate (“LIBOR”) plus 3.25% based upon the fixed charge coverage ratio of KEMET Corporation and its subsidiaries on a consolidated basis). The term of this borrowing was originally 31 days with total interest and principal payable at maturity, on October 28, 2013, however, it has been extended periodically and is currently due on November 23, 2014. For the six month period ended September 30, 2014, the Company borrowed an additional $14.3 million, of which $7.5 million was repaid during the period. These were the only borrowings under the revolving line of credit, and as of September 30, 2014, the Company's available borrowing capacity under the Loan and Security Agreement was $0.3 million (after the $16.0 million used for letters of credit as described below).

As described below in the section titled "Advanced Payment from OEM", a standby letter of credit for $16.0 million was delivered to the OEM on October 8, 2012. In fiscal year 2014, the Company issued two letters of credit for €1.1 million ($1.4 million) and €0.7 million ($0.9 million) related to the construction of the new manufacturing location in Italy which were canceled during February 2014 and April 2014, respectively. Outstanding letters of credit reduce the Company's availability under the Loan and Security Agreement.

Advanced Payment from OEM

On August 28, 2012, the Company entered into and amended an agreement (the “Agreement”) with an OEM, pursuant to which the OEM agreed to advance the Company $24.0 million (the “Advance Payment”). As of September 30, 2014 and March 31, 2014, the Company had $18.6 million and $20.4 million, respectively, outstanding under this agreement. On a monthly basis starting in June 2013, the Company began repaying the OEM an amount equal to a percentage of the aggregate purchase price of the capacitors sold to the OEM the preceding month, not to exceed $1.0 million per month. Pursuant to the terms of the Agreement, the percentage of the aggregate purchase price of capacitors sold to the OEM used to repay the Advance Payment will double, not to exceed $2.0 million per month, in the event that (1) the OEM provides evidence that the price charged by KEMET for a particular capacitor during any prior quarter was equal to or greater than 110% of the price paid by the OEM or its affiliates for a third-party part qualified for the same product, and shipping in volume during such period; and, (2) agreement cannot be reached between the OEM and the Company for a price adjustment during the current quarter which would bring KEMET’s price within 110% of the third-party price. In June 2015, the outstanding balance, if any, is due in full. Pursuant to the terms of the Agreement, the Company delivered to the OEM an irrevocable standby Letter of Credit in the amount of $16.0 million on October 8, 2012; and, on October 22, 2012, the Company received the Advance Payment from the OEM.

The OEM may demand repayment of the entire balance outstanding or draw upon the Letter of Credit if any of the following events occur while the Agreement is still in effect: (i) the Company commits a material breach of the Agreement, the statement of work or the master purchase agreement between the OEM and the Company; (ii) the Company’s credit rating issued by Standard & Poor’s Financial Services LLC or its successor or Moody’s Investors Services, Inc. or its successors drops below CCC+ or Caa1, respectively; (iii) the Company’s cash balance on the last day of any fiscal quarter is less than $60.0 million; (iv) the Letter of Credit has been terminated without being replaced prior to repayment of the Advance Payment amount; (v) the Company or substantially all of its assets are sold to a party other than a subsidiary of the Company; (vi) all or substantially all of the assets of a subsidiary of the Company, or any of the shares of such subsidiary, are sold, whose assets are used to develop and produce the Goods; (vii) the Company or any subsidiary which accounts for 20% or more of the Company’s consolidated total assets (“Company Entity”) applies for judicial or extra judicial settlement with its creditors, makes an assignment for the benefit of its creditors, voluntarily files for bankruptcy or has a receiver or trustee in bankruptcy appointed by reason of its insolvency, or in the event of an involuntary bankruptcy action, liquidation proceeding, dissolution or similar proceeding is filed against a Company Entity and not dismissed within sixty (60) days. To the Company’s best knowledge and belief, none of these triggers have been met including maintaining a minimum cash balance since the Company's cash balance (including restricted cash under the OEM agreement) exceeds the $60.0 million threshold.

10.5% Senior Notes

As of September 30, 2014 and March 31, 2014, the Company had outstanding $355.0 million in aggregate principal amount of the Company’s 10.5% Senior Notes due May 1, 2018 (the “10.5% Senior Notes”). The Company had interest payable related to the 10.5% Senior Notes included in the line item “Accrued expenses” on its Condensed Consolidated balance sheets of $15.5 million as of September 30, 2014 and March 31, 2014.
