||6. Bank loans In August 2021, the Company amended and restated the credit agreement (the “Amended Credit Agreement”) governing its unsecured revolving line of credit (the “Credit Facility”) with Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent, and the other lenders party thereto. The Amended Credit Agreement increased the aggregate principal amount of the Credit Facility from $250.0 million to $400.0 million, and extended the maturity date to August 24, 2025, with two six-month extension options or one 12-month extension option. The per annum rate of interest charged on borrowings is based on London Inter-bank Offered Rate (“LIBOR”) plus 0.70% to LIBOR plus 1.35%. Currently, the Company’s rate under the Credit Facility is LIBOR plus 0.70% per annum. In addition, the Company is required to pay an annual facility fee ranging from 0.10% to 0.25% per annum calculated on the aggregate committed amount of the Credit Facility (currently 0.10% per annum). The interest rate margin and facility fee may increase in the future based on the ratio of the Company’s total consolidated indebtedness to its consolidated gross asset value defined in accordance with the Amended Credit Agreement. The Credit Facility also features a sustainability-linked pricing component whereby the pricing can improve by 0.01%, if the Company meets certain sustainability performance targets, and an accordion feature whereby it has an option to increase commitments under the Credit Facility up to an additional $300.0 million. The Company had a $32.0 million balance outstanding, at an interest rate of 0.8%, on its Credit Facility at December 31, 2021 and a zero balance outstanding on its Credit Facility at December 31, 2020. Subsequent to December 31, 2021, the Company repaid in full the balance outstanding as of December 31, 2021. In connection with the Amended Credit Agreement, the Company paid $2.2 million of loan origination costs. The Company had $2.1 million and $0.2 million of total unamortized loan origination costs as of December 31, 2021 and 2020, respectively, which is included in other assets in the accompanying consolidated balance sheets. The Credit Facility requires the Company to meet certain covenants, all of which it was in compliance with at December 31, 2021. Interest on outstanding borrowings is payable monthly.
