Convertible Subordinated Debt

4.50% Notes

On October 31, 2012, we issued $60 million aggregate principal amount of 4.50% convertible subordinated notes due November 15, 2017, and on November 6, 2012 we issued an additional $10 million aggregate principal amount of 4.50% convertible subordinated notes due November 15, 2017 pursuant to an over-allotment provision (“4.50% notes”). These notes are convertible into shares of our common stock at a conversion rate of 607.1645 shares per $1,000 principal amount, a conversion price of approximately $1.65 per share. We may not redeem the notes prior to their maturity date although investors may convert the 4.50% notes into Quantum common stock until November 14, 2017 at their option. In addition, since purchasers are qualified institutional investors, as defined in Rule 144A under the Securities Act of 1933 (“Securities Act”), the 4.50% notes have not been registered under the Securities Act. We pay 4.50% interest per annum on the principal amount of the 4.50% notes semi-annually on May 15 and November 15 of each year beginning in May 2013. Interest began to accrue on October 31, 2012. The terms of the 4.50% notes are governed by an agreement dated October 31, 2012 between Quantum and U.S. Bank National Association. The 4.50% notes are subordinated to any existing indebtedness and other liabilities. We incurred and capitalized $2.3 million of fees for the 4.50% notes which are included in other long-term assets in our Consolidated Balance Sheets. These fees are amortized to interest expense over the term of the notes.

On November 15, 2010, we issued $135 million aggregate principal amount of 3.50% convertible subordinated notes due November 15, 2015 with a conversion price of $4.33 per share of our common stock (“3.50% notes”). We may not redeem the 3.50% notes prior to their maturity date although investors may convert the 3.50% notes into Quantum common stock until November 14, 2015 at their option. In addition, since purchasers are qualified institutional investors, as defined in Rule 144 under the Securities Act, the 3.50% notes have not been registered under the Securities Act. We pay 3.50% interest per annum on the principal amount of the 3.50% notes semi-annually on May 15 and November 15 of each year. The terms of the 3.50% notes are governed by an agreement dated November 15, 2010 between Quantum and U.S. Bank National Association. The 3.50% notes are subordinated to any existing indebtedness and other liabilities. We incurred and capitalized $5.0 million of loan fees in fiscal 2011 for the 3.50% notes which are included in other long-term assets in our Consolidated Balance Sheets. These fees are amortized to interest expense over the term of the notes.

4.375% Notes

On July 30, 2010, we paid $22.1 million plus $0.5 million in accrued and unpaid interest to redeem the 4.375% convertible subordinated notes outstanding at that date in accordance with the contractual terms at maturity. These notes matured August 1, 2010.

Long-Term Debt

Wells Fargo Credit Agreement

On March 29, 2012, we refinanced the senior secured credit agreement with Credit Suisse (“CS credit agreement”) by entering into a senior secured credit agreement with Wells Fargo Capital Finance, LLC providing a senior secured revolving credit facility up to $75 million, subsequently amended to $55 million (“WF credit agreement”). The WF credit agreement matures March 29, 2017, or August 16, 2015 if our 3.50% notes remain outstanding on that date. Quarterly, we are required to pay a 0.375% commitment fee on undrawn amounts under the revolving credit facility. There is a blanket lien on all of our assets under the WF credit agreement in addition to certain financial and reporting covenants.We borrowed $49.5 million on March 29, 2012 to repay all borrowings under the CS credit agreement. Amounts borrowed are included in long-term debt on the Consolidated Balance Sheets. We incurred and capitalized $1.0 million of fees related to the WF credit agreement which are included in other long-term assets in our Consolidated Balance Sheets. These fees are being amortized to interest expense over the term of the WF credit agreement.

There were two primary amendments made to the WF credit agreement during fiscal 2013. On June 28, 2012, the WF credit agreement was amended in order to allow the assignment of one third of the total revolver commitment to Silicon Valley Bank. This amendment also made certain other conforming and related modifications, including changes to the average liquidity requirements.

On January 31, 2013, the WF credit agreement was amended to decrease the line of credit and modify certain covenants. The maximum borrowing amount decreased to the lesser of $55 million or the amount of the monthly borrowing base and will remain at this level for the remaining term of the credit agreement. The average liquidity covenant was eliminated. The fixed charge coverage ratio covenant is applicable only in fiscal quarters in which liquidity is below $16.5 million and decreased from 1.2 to 1.1 for the 12 month period ending on the last day of any fiscal quarter in which the covenant is applicable. The liquidity requirement to avoid triggering mandatory field audits decreased from $20 million to $18.5 million commencing January 31, 2013 and will remain at this level for the remaining term of the credit agreement. Both the fixed charge coverage ratio and liquidity are defined in the WF credit agreement and the January 31, 2013 amendment.

On October 31, 2012, we repaid all outstanding borrowings under the WF credit agreement with $49.5 million of the proceeds from the 4.50% notes. We have letters of credit totaling $1.1 million, reducing the amount available to borrow to $53.9 million at March 31, 2013. As of March 31, 2013, we were in compliance with all covenants and had no outstanding balance on the line of credit.

Credit Suisse Credit Agreement

On July 12, 2007, we refinanced a prior credit facility by entering into a senior secured credit agreement with Credit Suisse providing a $50 million revolving credit facility and a $400 million senior secured term loan. We borrowed $400 million on the term loan to repay all borrowings under a prior credit facility used to fund the Advanced Digital Information Corporation acquisition. We incurred and capitalized $8.1 million of loan fees related to the CS credit agreement which were included in other long-term assets in our Consolidated Balance Sheets. These fees were amortized to interest expense over the respective loan terms. Interest accrued on the term loan at our option based on either, a prime rate plus a margin of 2.5%, or a LIBOR rate plus a margin of 3.5%. During fiscal 2011, we made principal payments of $81.7 million on the CS credit agreement term loan, and in fiscal 2012 we made principal payments of $104.3 million to fully extinguish the term loan and CS credit agreement.

Subordinated Term Loans

On November 15, 2010, we paid $121.7 million plus $1.8 million in accrued and unpaid interest to settle subordinated term loans with EMC International Company. As a result of the voluntary prepayment in full of these term loans, we have satisfied all of our obligations under these loans. We funded this payment using proceeds from the 3.50% convertible subordinated notes.

Loss on Debt Extinguishment

In fiscal 2012, in connection with fully extinguishing the CS term loan and credit agreement on March 29, 2012, we wrote off $2.3 million of unamortized debt costs related to the CS term loan and credit agreement.

In fiscal 2011, in connection with the repayment of our subordinated term loans on November 15, 2010, we wrote off $1.2 million of unamortized debt costs related to these term loans.
