Under our Revolving Credit Agreement, covenants include restrictions on liens, a maximum debt to earnings ratio, a minimum fixed charge coverage ratio and a change of control provision that may require acceleration of the repayment obligations under certain circumstances.
As of November 19, 2022, we had no outstanding borrowings and $1.8 million of outstanding letters of credit under our Revolving Credit Agreement.
We also maintain a letter of credit facility that allows us to request the participating bank to issue letters of credit on our behalf up to an aggregate amount of $25 million. The letter of credit facility is in addition to the letters of credit that may be issued under the Revolving Credit Agreement. As of November 19, 2022, we had $25.0 million in letters of credit outstanding under the letter of credit facility, which expires in June 2025.
In addition to the outstanding letters of credit issued under the committed facilities discussed above, we had $107.2 million in letters of credit outstanding as of November 19, 2022. These letters of credit have various maturity dates and were issued on an uncommitted basis.
As of November 19, 2022, the commercial paper borrowings, the $300 million 2.875% Senior Notes due January 2023 and the $500 million 3.125% Senior Notes due July 2023 were classified as long-term in the Consolidated Balance Sheets, as we have the current ability and intent to refinance them on a long-term basis through available capacity in our Revolving Credit Agreement. As of November 19, 2022, we had $2.2 billion of availability under our Revolving Credit Agreement, without giving effect to commercial paper borrowings, which would allow us to replace these short-term obligations with a long-term financing facility.
The Senior Notes contain a provision that repayment may be accelerated if we experience a change in control (as defined in the agreements). The Company’s borrowings under our Senior Notes contain minimal covenants, primarily restrictions on liens. All of the repayment obligations under its borrowing arrangements may be accelerated and come due prior to the applicable scheduled payment date if covenants are breached or an event of default occurs. As of November 19, 2022, we were in compliance with all covenants and expect to remain in compliance with all covenants under our borrowing arrangements.
As of November 19, 2022, the Company was in compliance with all covenants and expects to remain in compliance with all covenants under its borrowing arrangements
Our adjusted debt to earnings before interest, taxes, depreciation, amortization, rent and share-based compensation expense (“EBITDAR”) ratio was 2.2:1 as of November 19, 2022 and was 2.0:1 as of November 20, 2021. We calculate adjusted debt as the sum of total debt, financing lease liabilities and rent times six; and we calculate adjusted EBITDAR by adding interest, taxes, depreciation, amortization, rent, and share-based compensation expense to net income. Adjusted debt to EBITDAR is calculated on a trailing four quarter basis. We target our debt levels to a ratio of adjusted debt to EBITDAR in order to maintain our investment grade credit ratings. We believe this is important information for the management of our debt levels. We expect the ratio of adjusted debt to EBITDAR to return to pre-pandemic levels in the future, increasing debt levels. Once the target ratio is achieved, to the extent adjusted EBITDAR increases, we expect our debt levels to increase; conversely, if adjusted EBITDAR decreases, we would expect our debt levels to decrease. Refer to the “Reconciliation of Non-GAAP Financial Measures” section for further details of our calculation.
