The Company’s real property interests primarily consist of leasehold interests, acquired either through an up‑front payment or on an installment basis from property owners who have leased their property to companies that own telecommunications infrastructure assets at cell sites. The agreements that provide for the leasehold interests typically are easement agreements, which have stated terms up to 99 years and provide the Company with certain beneficial rights, but not obligations, with respect to the underlying cell site leases. The beneficial rights acquired include, principally, the right to receive the rental income related to the cell site lease with the in‑place tenant, and in certain circumstances, additional rents. In most cases, the stated term of the leasehold interest is longer than the remaining term of the cell site lease with the in‑place tenant, which provides the Company with the right and opportunity for renewals and extensions. Although the Company has the rights under the acquired leasehold interests over the duration of the entire term, typically, the underlying tenant can terminate their lease acquired by the Company within a short time frame (30‑ to 180‑day notice) without penalty. Under certain circumstances, the Company acquires the fee simple interest ownership, rather than acquiring a leasehold interest. In the instance in which a fee simple interest in the land is acquired, the Company is also assigned the existing cell site lease with the in-place tenant.

The Company often closes and funds its real property interest prepayment transactions through a third‑party intermediary. These intermediaries generally are the Company’s retained legal counsel in each jurisdiction. Funds for these transactions are typically deposited with the intermediary who releases the funds once all closing conditions are satisfied. In other circumstances, the Company deposits monies with the owners of the cell sites in advance of consummating a lease prepayment transaction, at which time all conditions are satisfied and remaining payments are made. Amounts held by others as deposits at December 31, 2020 (Successor) and December 31, 2019 (Predecessor) totaled $1,346 and $2,311, respectively, and were recorded as other long‑term assets in the Company’s consolidated balance sheets.

Commencing with the adoption of ASC 842 on January 1, 2019, the Company determines if a real property interest arrangement is a lease at the inception of the agreement. The Company considers an arrangement to be a lease if it conveys the right to control the use of the cell site or ground space underneath a communications site for a period of time in exchange for consideration. In cases in which the Company acquires a leasehold interest, the Company is both a lessor and a lessee. The weighted-average remaining lease term for the right-of-use assets categorized as finance leases was 38.2 years and 36.7 years as of December 31, 2020 (Successor) and December 31, 2019 (Predecessor), respectively. The Company recorded finance lease expense and interest expense associated with the lease liability in the consolidated statements of operations as follows:

	Successor		Predecessor
	Period from February 10, 2020 to December 31, 2020		Period from January 1, 2020 to February 9, 2020		Year ended December 31, 2019
Finance lease expense	$	6,922	$	425	$	1,235
Interest expense – lease liability	$	518	$	95	$	504

The Company’s lease agreements do not state an implicit borrowing rate; therefore, an internal incremental borrowing rate was determined based on information available at the lease commencement date for the purposes of determining the present value of lease payments. The incremental borrowing rate reflects the cost to borrow on a securitized basis in each geographical market. The weighted-average incremental borrowing rate was 2.8% and 7.9% as of December 31, 2020 (Successor) and December 31, 2019 (Predecessor), respectively.

	Successor		Predecessor
	Period from February 10 to December 31, 2020		Period from January 1 to February 9, 2020		Year ended December 31, 2019
Cash paid for amounts included in the measurement of finance lease liabilities:
Operating cash flows from finance leases	$	134	$	37	$	38
Financing cash flows from finance leases	$	6,044	$	845	$	1,255
Finance lease liabilities arising from obtaining right-of-use assets	$	19,312	$	1,346	$	16,989

For real property interests that are not accounted for under ASC 842, the Company applies the acquisition method of accounting, recording an intangible asset in cell site leasehold interests, net in the consolidated balance sheet. The recorded amount of the cell site leasehold interest represents the allocation of purchase price to the contractual cash flows acquired from the in-place tenant, as well as the right and opportunity for renewals.

Under certain circumstances, the contractual payments for the acquired cell site leasehold interests are made to property owners on a noninterest-bearing basis over a specified period of time, generally ranging from two to seven years. The Company is contractually obligated to fulfill such payments. Included in cell site leasehold interest liabilities in the consolidated balance sheets, the liabilities associated with cell site leasehold interests were initially measured at the present value of the unpaid payments.

For cell site leasehold interests accounted for under the acquisition method of accounting, amortization expense was $34,482 for the period from February 10 to December 31, 2020 (Successor), $2,031 for the period from January 1 to February 9, 2020 (Predecessor) and $16,930 for the year ended December 31, 2019 (Predecessor). As of December 31, 2020 (Successor), amortization expense to be recognized for each of the succeeding five years was as follows:

2021	$	44,217
2022		44,076
2023		44,006
2024		44,006
2025		43,986
Thereafter		631,238
	$	851,529

Maturities of finance lease liabilities and cell site leasehold interest liabilities as of December 31, 2020 (Successor) were as follows:

2022		7,796			3,095
2023		7,644			8,384

As of December 31, 2020 (Successor), the weighted average remaining contractual payment term for finance lease and cell site leasehold liabilities was 3.6 years.
