As of December 31, 2020, we had approximately $392 million of consolidated principal amount of long-term debt outstanding, comprised as follows: (1) Tower had approximately $104 million outstanding principal amount of Series G debentures, payable in five semi-annual consecutive equal installments from March 2021 to March 2023; (2) TPSCo had loans of approximately $107 million principal amount (the "JP Loan"), carrying a fixed interest rate of approximately 2% per annum, with principal scheduled to be repaid in nine semiannual payments between 2021 and 2025; (3) Tower and its affiliates had capital lease agreements outstanding in the amount of approximately $96 million from JA Mitsui Leasing, repayable between 2021 and 2024, and (4) Tower and its affiliates had other capital and operating leases in the amount of approximately $85 million repayable between 2021 and 2032. Carrying such an amount of long-term debt may have significant negative consequences on our business, including:
limiting our ability to fulfill our debt obligations and other liabilities;requiring the use of a substantial portion of our cash to service our indebtedness rather than investing our cash to fund our strategic growth opportunities and plans, working capital and capital expenditures;increasing our vulnerability to adverse economic and industry conditions;limiting our ability to obtain additional financing;limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we compete;placing us at a competitive disadvantage with respect to less leveraged competitors and competitors that have better access to capital resources;volatility in our non-cash financing expenses due to increases in the fair value of our debt obligations;fluctuations of the payable amounts in USD of the JP Loan or other expenses which are denominated in JPY; and potential enforcement by the lenders of their liens against our respective assets, as applicable, if an event of default occurs.
In order to service our debt, the applicable interest it carries and other liabilities and obligations and/or improve its terms and conditions and/or invest in strategic opportunities for growth and/or business development activities, in addition to our cash on hand and expected cash flow generation from operating activities, we may decide to obtain funds from additional sources including debt vehicles and/or re-financing, sale of new securities, sale of intellectual property and/or intellectual property licensing, as well as additional financing alternatives. However, there is no assurance that we will be able to obtain sufficient funding, if at all, from the financing sources detailed above or other sources in a timely manner (or on commercially reasonable terms) in order to allow us to fund our growth plans and/or cover, in a timely manner, all our costs, capital expenditure investments and all of our scheduled debt detailed above, liabilities and obligations, which may adversely affect our financial position and operations.
