Covenant terms	among other things, (i) modify the financial covenants and certain other provisions contained therein in a manner consistent with the amendments made to the Revolving Credit Facility, (ii) extend the maturity date to June 2027, (iii) add a $100 million delayed draw feature (that was drawn upon in June 2022) and (iv) change the interest rate benchmark from LIBOR to SOFR. The Term Loan bears interest at variable rates, based on the Company’s long-term senior unsecured debt ratings, equal to (i) the SOFR rate plus a spread (1.05% at September 30, 2022) or (ii) the alternative base rate plus a spread (0.0% at September 30, 2022). The Company may increase the principal amount of the Term Loan in the future to up to $800 million in the aggregate provided that existing or new lenders are identified to provide additional loan commitments.

The Company is required to comply with covenants similar to those contained in the Revolving Credit Facility. The Company was in compliance with these financial covenants at September 30, 2022.
