As of December 31, 2024, we had $3.2 billion of principal indebtedness outstanding, $236 million of which is characterized as short-term debt and presented within other current liabilities in the consolidated balance sheets. Our indebtedness includes unsecured 0.625% Convertible Senior Notes due 2025 that mature on October 1, 2025 (the "2025 Notes"), unsecured 1.00% Convertible Senior Notes due 2026 that mature on August 15, 2026 (the "2026 Notes"), unsecured 3.25% Convertible Senior Notes due 2027 that mature on September 15, 2027 (the "2027 Notes"), unsecured 3.50% Convertible Senior Notes due 2028 that mature on November 15, 2028 (the "2028 Notes", and together with the 2025 Notes, 2026 Notes and 2027 Notes, the "Non-Accreting Notes"), and 7.250% Senior Secured Notes due 2029 that mature on October 31, 2029 (the "2029 Secured Notes" and together with the Non-Accreting Notes, the "Notes"). At maturity of the Non-Accreting Notes, unless earlier purchased, redeemed or converted, we will settle any conversions in cash, shares of Wayfair's Class A common stock or a combination thereof, at our election. If any of the Non-Accreting Notes are not converted at or prior to maturity, we will be required to pay the holder thereof the principal amount in cash. At maturity of the 2029 Secured Notes, unless earlier purchased, we will be required to pay the holders thereof the principal amount in cash. We pay interest semiannually in arrears at fixed rates per annum of 0.625% for the 2025 Notes, 1.00% for the 2026 Notes, 3.25% for the 2027 Notes, 3.50% for the 2028 Notes and 7.250% for the 2029 Secured Notes. Under certain circumstances, the holders of the Notes may require us to repay all or a portion of the principal and interest outstanding under the Notes in cash prior to the maturity date, which could have an adverse effect on our liquidity and financial condition.
We have the ability to borrow up to $600 million under our senior secured revolving credit facility (the "Revolver") to finance working capital and provide funds for permitted acquisitions, repurchases of equity interests and other general corporate purposes. If we draw down on this facility, our interest expense and principal repayment requirements will increase, which could have an adverse effect on our financial results and our ability to make payments on the Notes. Further, the agreements governing the Revolver contain numerous requirements, including affirmative, negative and financial covenants. As a result of these covenants, our ability to respond to changes in business and economic conditions and engage in beneficial transactions, including to obtain additional financing as needed, may be restricted. Our failure to comply with any of these covenants or to meet any payment obligations under the Revolver could result in an event of default which, if not cured or waived, would result in any amounts outstanding, including any accrued interest and unpaid fees, becoming immediately due and payable. We might not have sufficient working capital or liquidity to satisfy any repayment obligations in the event of an acceleration of those obligations.
Our business may not be able to generate sufficient cash flow from operations, and we can give no assurance that future borrowings will be available to us in amounts sufficient to enable us to pay our indebtedness as such indebtedness matures, including the Notes, and to fund our other liquidity needs. If this occurs, we will need to refinance all or a portion of our indebtedness on or before maturity. Any new or refinanced debt may be subject to substantially higher interest rates and restrictive covenants that could reduce our operational flexibility, and there can be no assurance that we will be able to refinance any of our indebtedness on commercially reasonable terms, or at all. We may need to adopt one or more alternatives, such as reducing or delaying planned expenses and capital expenditures, selling assets, restructuring debt, or obtaining additional equity or debt financing. We may sell Class A common stock, convertible securities and other equity securities in one or more transactions at prices and in a manner as we may determine from time to time. Our Non-Accreting Notes are and any future issuance of equity or equity-linked securities would be dilutive to holders of our Class A common stock. New investors in such subsequent transactions could gain rights, preferences and privileges senior to those of holders of our Class A common stock or our Non-Accreting Notes. These alternative strategies may not be implemented on satisfactory terms, if at all. Our ability to refinance our indebtedness or obtain additional financing, or to do so on commercially reasonable terms, may depend on, among other things, our financial condition at the time, our credit rating, restrictions in agreements governing our indebtedness, and other factors, including the condition of the financial markets and the markets in which we compete.
Further, we may from time to time seek to retire, restructure, repurchase or redeem, or otherwise mitigate the equity dilution associated with, our outstanding convertible debt, through cash purchases, stock buybacks of some or all of the shares underlying the Non-Accreting Notes, and/or exchanges for equity or debt, in open-market purchases, privately negotiated transactions or otherwise. Such repurchases, exchanges or liability management exercises, if any, will be upon such terms and at such prices and sizes as we may determine, and will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors. The amounts involved may be material.
Current capital market conditions, including the impact of inflation, have increased borrowing rates and can be expected to significantly increase our cost of capital as compared to prior periods should we seek additional funding. Quantitative tightening by the U.S. Federal Reserve, along with other central banks around the world, may further negatively affect our short-term ability or desire to incur debt. Moreover, global capital markets have undergone periods of significant volatility and uncertainty in the past, and there can be no assurance that such financing alternatives will be available to us on favorable terms or at all, should we determine it necessary or advisable to seek additional capital.
If we do not generate sufficient cash flow from operations, and additional borrowings, refinancings or proceeds from equity or debt issuances or asset sales are not available to us, we may not have sufficient cash to enable us to meet all of our obligations, including our obligations under the Revolver or the Notes. Further, our failure to service our existing and future indebtedness or other liabilities or maintain compliance with the financial covenants in our debt agreements could result in default under the related debt agreements or other alternatives that could result in our stockholders losing some or all of their equity investment in us.
