2019 Senior Notes. In September 2014, we issued $350.0 million aggregate principal amount of unsecured 5.50% senior notes due October 1, 2019 (the "2019 Senior Notes"). On April 4, 2019, we used cash on hand to redeem all of our $350.0 million unsecured senior notes due October 2019, plus accrued but unpaid interest, at the redemption price equal to 100% of par value.

2021 Senior Notes. In March 2016, we issued $475.0 million aggregate principal amount of unsecured 6.75% senior notes due March 15, 2021 (the "2021 Senior Notes"). The 2021 Senior Notes bear interest at the rate of 6.75% per annum with interest payable semi-annually in arrears on March 15 and September 15 of each year beginning on September 15, 2016. The net proceeds from the offering were used for general corporate purposes, including acquisitions and dividends. We incurred fees and expenses related to the 2021 Senior Notes offering of $8.1 million, which were capitalized during the first quarter of fiscal 2016 and are being amortized as interest expense over the term of the notes. The 2021 Senior Notes were sold in a private placement and are not registered under the Securities Act of 1933 (the "Securities Act"). The 2021 Senior Notes were offered in the United States to "qualified institutional buyers" pursuant to the exemption from registration under Rule 144A of the Securities Act and in exempted offshore transactions pursuant to Regulation S under the Securities Act.

The indenture governing the 2021 Senior Notes does not contain financial covenants but does contain covenants which place certain restrictions on us and our subsidiaries, including limitations on asset sales, additional liens, investments, stock repurchases, the incurrence of additional debt and the repurchase of debt that is junior to the 2021 Senior Notes. In addition, the indenture restricts payments of dividends to stockholders (other than dividends payable in shares of capital stock) if one of the following conditions exist: (i) an event of default has occurred, (ii) we could not incur additional debt under the general debt covenant of the indentures or (iii) the sum of the proposed dividend and all other dividends and other restricted payments made under the indenture from the date of the indenture governing the 2021 Senior Notes exceeds the sum of 50% of consolidated net income plus 100% of net proceeds from capital stock sales and other amounts set forth in and determined as provided in the indenture. These restrictions are subject to exceptions and qualifications, including that we can pay up to $175 million in dividends to stockholders in each fiscal year and we can pay dividends and make other restricted payments in an unlimited amount if our leverage ratio on a pro forma basis after giving effect to the dividend payment and other restricted payments would be less than or equal to 1.0:1.0.

The indenture contains customary events of default, including payment defaults, breaches of covenants, failure to pay certain judgments and certain events of bankruptcy, insolvency and reorganization. If an event of default occurs and is continuing, the principal amount of the 2021 Senior Notes, plus accrued and unpaid interest, if any, may be declared immediately due and payable. These amounts automatically become due and payable if an event of default relating to certain events of bankruptcy, insolvency or reorganization occurs.

We maintain an asset-based revolving credit facility (the “Revolver”) with a borrowing base capacity of $420 million and a maturity date of November 2022. The Revolver also includes a $200 million expansion feature and $50 million letter of credit sublimit, and allows for an incremental $50 million first-in, last-out facility. The applicable margins for prime rate loans range from 0.25% to 0.50% and, for the London Interbank Offered ("LIBO") rate loans, range from 1.25% to 1.50%. The Revolver is secured by substantially all of the assets of GameStop Corp. and the assets of its domestic subsidiaries.

Borrowing availability under the Revolver is limited to a borrowing base which allows us to borrow up to 90% of the appraisal value of the inventory, plus 90% of eligible credit card receivables, net of certain reserves. The borrowing base provides for borrowing of up to 92.5% of the appraisal value during the period between July 15 and October 15 of each year. Letters of credit reduce the amount available to borrow under the Revolver by an amount equal to the face value of the letters of credit. Our ability to pay cash dividends, redeem options and repurchase shares is generally permitted, except under certain circumstances, including if either (1) excess availability under the Revolver is less than 20%, or is projected to be within six months after such payment or (2) excess availability under the Revolver is less than 15%, or is projected to be within six months after such payment, and the fixed charge coverage ratio, as calculated on a pro-forma basis for the prior 12 months, is 1.0:1.0 or less. In the event that excess availability under the Revolver is at any time less than the greater of (1) $30 million or (2) 10% of the lesser of the total commitment or the borrowing base, we will be subject to a fixed charge coverage ratio covenant of 1.0:1.0.

The Revolver places certain restrictions on us and our subsidiaries, including limitations on asset sales, additional liens, investments, loans, guarantees, acquisitions and the incurrence of additional indebtedness. Absent consent from our lenders, we may not incur more than $1 billion of senior secured debt and $750 million of additional unsecured indebtedness to be limited to $250 million in general unsecured obligations and $500 million in unsecured obligations to finance acquisitions valued at $500 million or more.

The per annum interest rate under the Revolver is variable and is calculated by applying a margin (1) for prime rate loans of 0.25% to 0.50% above the highest of (a) the prime rate of the administrative agent, (b) the federal funds effective rate plus 0.50% and (c) the LIBO rate for a one month interest period as determined on such day plus 1.00%, and (2) for LIBO rate loans of 1.25% to 1.50% above the LIBO rate. The applicable margin is determined quarterly as a function of our average daily excess availability under the facility. In addition, we are required to pay a commitment fee of 0.25% for any unused portion of the total commitment under the Revolver. As of February 1, 2020, the applicable margin was 0.25% for prime rate loans and 1.25% for LIBO rate loans.

The Revolver provides for customary events of default with corresponding grace periods, including failure to pay any principal or interest when due, failure to comply with covenants, any material representation or warranty made by us or the borrowers proving to be false in any material respect, certain bankruptcy, insolvency or receivership events affecting us or our subsidiaries, defaults relating to certain other indebtedness, imposition of certain judgments and mergers or the liquidation of the Company or certain of its subsidiaries. During fiscal 2019, we had no borrowings or repayments under our revolving credit facility. As of February 1, 2020, total availability under the Revolver was $270.3 million, with no outstanding borrowings and outstanding standby letters of credit of $7.3 million. During the first quarter of fiscal 2020, we borrowed $150 million on our Revolver. We are currently in compliance with the financial requirements of the Revolver.

In September 2007, our Luxembourg subsidiary entered into a $20.0 million Uncommitted Line of Credit (the “Line of Credit”) with Bank of America. There is no term associated with the Line of Credit and Bank of America may withdraw the facility at any time without notice. The Line of Credit is available to our foreign subsidiaries for use primarily as a bank overdraft facility for short-term liquidity needs and for the issuance of bank guarantees and letters of credit to support operations. As of February 1, 2020, there were no cash overdrafts outstanding under the Line of Credit and bank guarantees outstanding totaled $9.0 million.
