On December 18, 2018, SpartanNash Company and certain of its subsidiaries entered into an amendment (the “Amendment”) to the Company’s Amended and Restated Loan and Security Agreement (the “Credit Agreement”). The principal changes of the amendment included an extension of the maturity date of the loans from December 20, 2021 to December 18, 2023, the ability to increase the size of the Tranche A revolving loan to $975 million from $900 million, an amendment to the interest rate grid such that rates for the Tranche A-1 revolving loans ($40 million capacity) are now LIBOR plus 2.25% to LIBOR plus 2.50%, a reload of the Tranche A-2 term loan ($60 million capacity) and a reset of certain advance rates for the borrowing base. In the third quarter of 2019, the Company executed an early payment of the Tranche A-2 term loan. The Company has the ability to increase the size of the Credit Agreement by an additional $325 million, subject to certain conditions. The Company’s obligations under the Credit Agreement are secured by substantially all of the Company’s personal and real property. The Company may repay all loans in whole or in part at any time without penalty.

Availability under the Credit Agreement is based upon advance rates on certain asset categories owned by the Company, including, but not limited to the following: inventory, accounts receivable, real estate, prescription lists, cigarette tax stamps, and rolling stock.

The Credit Agreement imposes certain requirements, including limitations on dividends and investments, limitations on the Company’s ability to incur debt, make loans, acquire other companies, change the nature of the Company’s business, enter a merger or consolidation, or sell assets. These requirements can be more restrictive depending upon the Company’s Excess Availability, as defined under the Credit Agreement.

Borrowings under the credit facility bear interest at the Company’s option as either Eurodollar loans or Base Rate loans, subject to a grid based upon Excess Availability. The interest rate terms for each of the aforementioned tranches are as follows:

Credit	Outstanding as of
Facility	December 28, 2019
Tranche	(In thousands)		Eurodollar Rate	Base Rate
Tranche A	$	609,599	LIBOR plus 1.25% to 1.50%	Greater of:	(i) the Federal Funds Rate plus 0.75% to 1.00%
					(ii) the Eurodollar Rate plus 2.25% to 2.50%
					(iii) the prime rate plus 0.25% to 0.50%
Tranche A-1	$	30,810	LIBOR plus 2.25% to 2.50%	Greater of:	(i) the Federal Funds Rate plus 1.75% to 2.00%
					(ii) the Eurodollar Rate plus 2.25% to 2.50%
					(iii) the prime rate plus 1.25% to 1.50%

The Company also incurs an unused line of credit fee on the unused portion of the loan commitments at a rate of 0.25%.

The Credit Agreement requires that the Company maintain Excess Availability of 10% of the borrowing base, as defined in the Credit Agreement. The Company is in compliance with all financial covenants as of December 28, 2019 and had Excess Availability after the 10% requirement of $236.8 million and $262.0 million at December 28, 2019 and December 29, 2018, respectively. The Credit Agreement provides for the issuance of letters of credit, of which $11.7 million were outstanding as of December 28, 2019 and December 29, 2018.

The weighted average interest rate for all borrowings, including loan fee amortization, was 4.56% for 2019.

At December 28, 2019, aggregate annual maturities and scheduled payments of long-term debt are as follows:
