Amortization of customer relationship value, acquired in-place lease value and other intangibles (a component of depreciation and amortization expense) was approximately $61.6 million and $67.7 million for the three months ended March 31, 2022 and 2021, respectively. Amortization of acquired below-market leases, net of acquired above-market leases, resulted in an increase in rental and other services revenue of $0.2 million and a decrease of $(1.4) million for the three months ended March 31, 2022 and 2021, respectively. Estimated annual amortization for each of the five succeeding years and thereafter, commencing April 1, 2022 is as follows:
