Amended Revolving Credit Facility In April 2017, the Company entered into a $600,000 revolving credit facility, which was subsequently amended and extended in August 2021 (as amended, the “Amended Revolving Credit Facility”). The Amended Revolving Credit Facility, which matures on August 24, 2026, provides for a five year unsecured revolving loan facility on a committed basis. The interest rate for borrowings under the Amended Revolving Credit Facility is based on either LIBOR or a base rate, plus a spread based on the Company’s consolidated leverage ratio at the end of each fiscal reporting quarter. The Amended Revolving Credit Facility also includes procedures for the succession from LIBOR to an alternative benchmark rate. Depending on the interest period the Company selects, interest may be payable every one, two or three months. Interest is reset at the end of each interest period. The Company currently elects to have loans under the Amended Revolving Credit Facility bear interest based on LIBOR with one-month interest periods. The Amended Revolving Credit Facility permits up to $50,000 to be used to fund letters of credit. The Amended Revolving Credit Facility also permits the Company to request one or more incremental term loan facilities and/or to increase the revolving loan commitments in an aggregate amount not to exceed $300,000. Subject to certain limitations, each such incremental term loan facility or revolving loan commitment increase will be on terms as agreed to by the Company, the administrative agent and the lenders providing such financing. Outstanding letters of credit were $5,439 and $4,235 at February 26, 2022 and August 28, 2021, respectively. Uncommitted Credit Facilities During the second quarter of fiscal year 2022, the Company extended and amended two of the three uncommitted credit facilities entered into or amended during fiscal year 2021. The third uncommitted credit facility was extended and amended in March 2022. All three of these amendments implemented the Secured Overnight Financing Rate (“SOFR”) as the replacement of the LIBOR benchmark. These facilities (collectively, the “Uncommitted Credit Facilities” and, together with the Amended Revolving Credit Facility, the “Credit Facilities”) total $208,000 in aggregate maximum uncommitted availability, under which $200,000 and $201,500 was outstanding at February 26, 2022 and August 28, 2021, respectively, and are included in the Current portion of debt including obligations under finance leases on the Company’s unaudited Condensed Consolidated Balance Sheets. Borrowings under the Uncommitted Credit Facilities are due at the end of the applicable interest period, which is typically one month but may be up to six months and may be rolled over to a new interest period at the option of the applicable lender. The Company’s lenders have, in the past, been willing to roll over the principal amount outstanding under the Uncommitted Credit Facilities at the end of each interest period but may not do so in the future. Each Uncommitted Credit Facility matures within one year of entering into such Uncommitted Credit Facility and contains certain limited covenants which are substantially the same as the limited covenants contained in the Amended Revolving Credit Facility. All of the Uncommitted Credit Facilities are unsecured and rank equally in right of payment with the Company’s other unsecured indebtedness. Because the interest rates on the Uncommitted Credit Facilities have recently been lower than the interest rates which are available on the Company’s other sources of financing, the Company has used, and intends to use in the future, the Uncommitted Credit Facilities for opportunistic refinancing of the Company’s existing indebtedness. The Company does not presently view the Uncommitted Credit Facilities as sources of incremental debt financing of the Company due to the uncommitted nature of the Uncommitted Credit Facilities, but reserves the right to use the Uncommitted Credit Facilities to incur additional debt where it considers it appropriate under the then-existing credit market conditions. During the twenty-six-week period ended February 26, 2022, the Company borrowed an aggregate $184,000 and repaid an aggregate $134,500 under the Credit Facilities. As of February 26, 2022 and August 28, 2021, the weighted-average interest rates on borrowings under the Credit Facilities were 1.14% and 1.11%, respectively. Private Placement Debt In July 2016, the Company completed the issuance and sale of $75,000 aggregate principal amount of 2.65% Senior Notes, Series A, due July 28, 2023, and $100,000 aggregate principal amount of 2.90% Senior Notes, Series B, due July 28, 2026; in June 2018, the Company completed the issuance and sale of $20,000 aggregate principal amount of 3.79% Senior Notes, due June 11, 2025; and, in March 2020, the Company completed the issuance and sale of $50,000 aggregate principal amount of 2.60% Senior Notes, due March 5, 2027 (collectively, the “Private Placement Debt”). Interest is payable semiannually at the fixed stated interest rates. All of the Private Placement Debt is unsecured. Shelf Facility Agreements In January 2018, the Company entered into Note Purchase and Private Shelf Agreements with MetLife Investment Advisors, LLC (the “Met Life Note Purchase Agreement”) and PGIM, Inc. (the “Prudential Note Purchase Agreement” and, together with the Met Life Note Purchase Agreement, the “Shelf Facility Agreements”). Each of the MetLife Note Purchase Agreement and the Prudential Note Purchase Agreement provides for an uncommitted facility for the issuance and sale of up to an aggregate total of $250,000 of unsecured senior notes, at a fixed rate. Pursuant to the terms of the Shelf Facility Agreements, no new unsecured senior notes may be issued and sold after January 12, 2021. As of February 26, 2022, $50,000 aggregate principal amount of 3.04% Senior Notes, due January 12, 2023 (which is included in the Current portion of debt including obligations under finance leases on the Company's unaudited Condensed Consolidated Balance Sheet as of February 26, 2022), and $50,000 aggregate principal amount of 2.40% Senior Notes, due March 5, 2024, were outstanding under notes issued in private placements pursuant to the Shelf Facility Agreements. Covenants Each of the Credit Facilities, the Private Placement Debt and the Shelf Facility Agreements imposes several restrictive covenants, including the requirement that the Company maintain a maximum consolidated leverage ratio of total indebtedness to EBITDA (earnings before interest expense, taxes, depreciation, amortization and stock-based compensation) of no more than 3.00 to 1.00 (or, at the election of the Company after it consummates a material acquisition, a four-quarter temporary increase to 3.50 to 1.00), and a minimum consolidated interest coverage ratio of EBITDA to total interest expense of at least 3.00 to 1.00, during the terms of the Credit Facilities, the Private Placement Debt and the Shelf Facility Agreements. On February 26, 2022, the Company was in compliance with the operating and financial covenants of the Credit Facilities, the Private Placement Debt and the Shelf Facility Agreements.
