On January 1, 2019, Mid Penn adopted ASU No. 2016-02, Leases (Topic 842), and all subsequent ASUs that modified Topic 842, which primarily affected the accounting treatment for operating lease agreements in which Mid Penn is the lessee. As of the January 1, 2019 adoption date, Mid Penn leased twenty-four branch locations under non-cancelable operating leases, which expire at various dates through the year ending December 31, 2035. Three of Mid Penn’s operating leases are with related parties. Subsequent to the adoption of Topic 842, Mid Penn entered into a lease agreement for one facility under a non-cancelable finance lease, which commenced March 1, 2019 and expires February 28, 2039.

In 2016, Mid Penn entered into two subleasing agreements with unrelated parties on one of its properties under an operating lease. Both subleases included escalation clauses. The first sublease agreement began on April 1, 2016, while the second sublease began on July 1, 2016. One sublease was terminated during the first quarter of 2019 due to the bankruptcy of the tenant. The remaining sublease ends on March 31, 2021.

Operating and finance lease right-of-use assets, as well as operating lease liabilities, are presented as separate line items on the Consolidated Balance Sheet, while finance lease liabilities are classified as a component of long-term debt. Mid Penn has elected not to include short-term leases (i.e., leases with initial terms of twelve months or less) or equipment leases (deemed immaterial) on the Consolidated Balance Sheet.

There were no sale and leaseback transactions, leveraged leases, or leases that had not commenced as of June 30, 2020.

Below is a summary of the operating and finance lease right-of-use assets and related lease liabilities, as well as the weighted average lease term (in years) and weighted average discount rate for each of the lease classifications as of June 30, 2020 and December 31, 2019.
