DEBT | 8. DEBT Credit Agreement In October 2011, we entered into a Second Amended and Restated Credit Agreement (the "Credit Agreement") which amended and restated our July 2007 Credit Agreement. The Credit Agreement provides for borrowings of up to $100,000 which may be increased by up to $40,000 pursuant to the terms of the Credit Agreement, and is secured by substantially all of our assets and the equity of our subsidiaries. The Credit Agreement expires on October 17, 2016. Revolving loans under the Credit Agreement bear interest at our election of (a) 1.50% to 2.00% above a certain base rate (4.75% at June 30, 2014), or (b) 2.50% to 3.00% above the LIBOR Rate (approximately 2.66% at June 30, 2014), with the margin rate subject to the achievement of certain average liquidity levels. We are also required to pay a monthly fee on the unused available balance, ranging from 0.375% to 0.50% based on availability. We had no outstanding borrowings at June 30, 2014 and March 31, 2014. Availability under the Credit Agreement is restricted by our United States and United Kingdom based accounts receivable and inventory balances. The Credit Agreement also allows for the issuance of letters of credit in an aggregate amount of up to $25,000. Information related to availability on our Credit Agreement is as follows:
|  | June 30, 2014 |  | March 31, 2014 |
--- | --- | --- | --- | --- | ---
Available borrowings |  | $ | 57,316 |  | $ | 63,630 |
Outstanding letters of credit |  |  | 1,664 |  |  | 1,664 |
We recorded interest expense and fees related to the Credit Agreement of $159 for each of the three months ended June 30, 2014 and 2013. The Credit Agreement contains covenants that substantially limit us and our subsidiaries' ability to: create, incur, assume or be liable for indebtedness; dispose of assets outside the ordinary course of business; acquire, merge or consolidate with or into another person or entity; create, incur or allow any lien on any of their respective properties; make investments; or pay dividends or make distributions (each subject to certain limitations); or optionally prepay any indebtedness (subject to certain exceptions, including an exception permitting the redemption of the Company's unsecured convertible senior notes upon the meeting of certain minimum liquidity requirements). In addition, the Credit Agreement provides for certain events of default such as nonpayment of principal and interest, breaches of representations and warranties, noncompliance with covenants, acts of insolvency, default on indebtedness held by third parties and default on certain material contracts (subject to certain limitations and cure periods). The Credit Agreement also contains a requirement that we maintain an interest coverage ratio of more than one to one for the trailing twelve month period, if certain average liquidity levels fall below $30,000. As of June 30, 2014, we were in compliance with all covenants and requirements outlined in the Credit Agreement. 4.375% Convertible Notes Due 2014 In June 2009, we issued $138,000 aggregate principal amount of 4.375% Convertible Notes due 2014 (the "4.375% Convertible Notes"). The issuance of the 4.375% Convertible Notes included $18,000 related to the exercise of an over-allotment option by the underwriters. Interest on the 4.375% Convertible Notes was paid semi-annually in arrears on June 1st and December 1st of each year, and commenced on December 1, 2009. The 4.375% Convertible Notes were scheduled to mature on June 1, 2014, unless earlier redeemed or repurchased by the Company or converted. On June 12, 2013, we issued a notice of redemption calling all of our outstanding 4.375% Convertible Notes, in the aggregate principal amount of $138,000, for redemption on August 29, 2013 at a redemption price of $1 per $1 principal amount, plus accrued and unpaid interest up to, but not including, the redemption date (the period from June 12, 2013 to August 29, 2013 is the "Notice Period"). Holders who elected to convert during the Notice Period were entitled to make-whole shares in addition to such shares they would otherwise be entitled to receive upon conversion. The notice of redemption specified that we would settle any 4.375% Convertible Notes surrendered for conversion in connection with the redemption on a combination settlement basis by paying cash up to a cash amount equal to $166,000 in the aggregate of converted notes and delivering shares of our common stock in respect of the amount, if any, by which our conversion obligation exceeded such cash amount. During the Notice Period, $137,993 of 4.375% Convertible Notes were converted for $165,992 in cash and 3,217,000 shares of our common stock. On August 29, 2013, we paid $7 in cash and we redeemed $7 of 4.375% Convertible Notes. In connection with the June 2009 offering of the 4.375% Convertible Notes, we entered into convertible note hedge transactions which were expected to reduce the potential dilution to our common stock upon conversion of the 4.375% Convertible Notes. The transactions included options to purchase approximately 12,927,000 shares of common stock at $10.675 per share, expiring on June 1, 2014, for a total cost of approximately $43,600, which was charged to additional paid-in capital. Separately, in June 2009, the Company entered into warrant transactions with a strike price of $14.945 per share. The warrants covered approximately 12,927,000 shares of the Company's common stock and were scheduled to expire on August 30, 2014, for total proceeds of approximately $26,300, which was credited to additional paid-in capital. On June 12, 2013, the Company entered into Unwind Agreements with respect to the convertible note hedge transactions and Unwind Agreements with respect to the warrant transactions with each of the hedge counterparties (collectively, the "Unwind Agreements"). Pursuant to the terms of the Unwind Agreements, and in connection with the Company's issuance of a notice of redemption for all the 4.375% Convertible Notes, the Company had the right to deliver a notice to the hedge counterparties, prior to the redemption date set forth in such redemption notice, designating an early termination date for the convertible note hedge transactions and warrant transactions. The hedge counterparties owed a cash payment to the Company as a result of the early termination of the convertible note hedge transactions that was calculated based on its current fair market value. The Company owed a cash payment to the warrant holders, as applicable, as a result of the early termination of the warrant transactions that was calculated based on its current fair market value. As a result of the Unwind Agreements, the convertible note hedge transactions and warrant transactions were accounted for as derivatives whereby the fair values of these transactions were reported as a convertible note hedge receivable and as a convertible note warrant liability with an offsetting impact to additional paid-in capital. Gains and losses on the derivatives resulting from changes in the fair value were reported in interest and other, net, in our Condensed Consolidated Statements of Operations. In August 2013, the payment received from unwinding the associated convertible note hedge transactions resulted in proceeds to us of $84,429, offset by $55,651 we paid the warrant holders. The following table provides the components of interest expense related to our 4.375% Convertible Notes, which was extinguished in August 2013:

1.75% Convertible Notes Due 2016 On November 16, 2011, we issued $250,000 aggregate principal amount of 1.75% Convertible Notes due 2016 (the "1.75% Convertible Notes"). Interest on the 1.75% Convertible Notes is payable semi-annually in arrears on June 1st and December 1st of each year, commencing on June 1, 2012. The 1.75% Convertible Notes mature on December 1, 2016, unless earlier repurchased by the Company or converted. The Company does not have the right to redeem the 1.75% Convertible Notes prior to maturity. The 1.75% Convertible Notes are convertible at an initial conversion rate of 52.3745 shares of our common stock per $1 principal amount of 1.75% Convertible Notes (representing an initial conversion price of approximately $19.093 per share of common stock for a total of approximately 13,094,000 underlying conversion shares) subject to adjustment in certain circumstances. Holders may convert the 1.75% Convertible Notes at their option prior to the close of business on the business day immediately preceding June 1, 2016 only under the following circumstances: (1) during any fiscal quarter commencing after March 31, 2012, if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; (2) during the five business day period after any 10 consecutive trading day period (the "measurement period") in which the trading price per $1 principal amount of 1.75% Convertible Notes for each day of that measurement period was less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate on each such day; or (3) upon the occurrence of specified corporate events. On and after June 1, 2016 until the close of business on the business day immediately preceding the maturity date, holders may convert their 1.75% Convertible Notes at any time, regardless of the foregoing circumstances. Upon conversion, the 1.75% Convertible Notes may be settled, at our election, in cash, shares of our common stock, or a combination of cash and shares of the Company's common stock. Upon the occurrence of certain fundamental changes involving the Company, holders of the 1.75% Convertible Notes may require us to purchase all or a portion of their 1.75% Convertible Notes for cash at a price equal to 100% of the principal amount of the notes to be purchased, plus accrued and unpaid interest (including additional interest, if any) to, but excluding, the fundamental change purchase date. The indenture governing the 1.75% Convertible Notes contains customary terms and covenants and events of default. If an event of default (as defined therein) occurs and is continuing, the Trustee by notice to the Company, or the holders of at least 25% in aggregate principal amount of the 1.75% Convertible Notes then outstanding by notice to the Company and the Trustee, may, and the Trustee at the request of such holders shall, declare 100% of the principal of and accrued and unpaid interest (including additional interest, if any) on all the 1.75% Convertible Notes to be due and payable. In the case of an event of default arising out of certain bankruptcy events, 100% of the principal of and accrued and unpaid interest (including additional interest, if any), on the 1.75% Convertible Notes will automatically become due and payable immediately. As of June 30, 2014, we were in compliance with all covenants and requirements outlined in the indenture governing the 1.75% Convertible Notes. The 1.75% Convertible Notes are senior unsecured obligations and rank senior in right of payment to our existing and future indebtedness that is expressly subordinated in right of payment to the 1.75% Convertible Notes; equal in right of payment to our existing and future indebtedness that is not so subordinated; effectively junior in right of payment to any of our secured indebtedness to the extent of the value of the assets securing such indebtedness; and structurally junior to all existing and future indebtedness incurred by our subsidiaries.

1.00% Convertible Notes Due 2018 On June 18, 2013, we issued $250,000 aggregate principal amount of 1.00% Convertible Notes due 2018 (the "1.00% Convertible Notes" and together with the 1.75% Convertible Notes, the "Convertible Notes"). The 1.00% Convertible Notes were issued at 98.5% of par value for proceeds of $246,250. Interest on the 1.00% Convertible Notes is payable semi-annually in arrears on July 1st and January 1st of each year, commencing on January 1, 2014. The 1.00% Convertible Notes mature on July 1, 2018, unless earlier repurchased by the Company or converted. The Company does not have the right to redeem the 1.00% Convertible Notes prior to maturity. The Company also granted the underwriters a 30-day option to purchase up to an additional $37,500 principal amount of 1.00% Convertible Notes to cover overallotments, if any. On July 17, 2013, the Company closed its public offering of $37,500 principal amount of the Company's 1.00% Convertible Notes as a result of the underwriters exercising their overallotment option in full on July 12, 2013, bringing the total proceeds to $283,188. The 1.00% Convertible Notes are convertible at an initial conversion rate of 46.4727 shares of our common stock per $1 principal amount of 1.00% Convertible Notes (representing an initial conversion price of approximately $21.52 per share of common stock for a total of approximately 13,361,000 underlying conversion shares) subject to adjustment in certain circumstances. Holders may convert the 1.00% Convertible Notes at their option prior to the close of business on the business day immediately preceding January 1, 2018 only under the following circumstances: (1) during any fiscal quarter commencing after September 30, 2013, if the last reported sale price of the common stock for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter is greater than or equal to 130% of the applicable conversion price on each applicable trading day; (2) during the five business day period after any 10 consecutive trading day period (the "measurement period") in which the trading price per $1 principal amount of 1.00% Convertible Notes for each day of that measurement period was less than 98% of the product of the last reported sale price of our common stock and the applicable conversion rate on each such day; or (3) upon the occurrence of specified corporate events.
