Amortization of acquired below-market leases, net of acquired above-market leases, resulted in an increase in rental and other services revenue of $1.7 million and $0.3 million for the three months ended June 30, 2023 and 2022, respectively, and approximately $3.5 million and $0.6 million for the six months ended June 30, 2023 and 2022, respectively.
