Lease Commitments |
Lease Commitments | Note 21—Lease Commitments On January 1, 2019, we adopted the requirements of Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842). The purpose of the update was to increase transparency and comparability between organizations that enter into lease agreements. The key difference between the previous guidance and the update is the recognition of a right-of-use asset (ROU) and lease liability on the statement of financial position for those leases previously classified as operating leases under the old guidance. ASC Topic 842 defines a lease as a contract, or part of a contract, that conveys the right to control the use of identified property, plant, or equipment (an identified asset) for a period of time in exchange for consideration. In applying this standard, we reviewed our material contracts to determine if they included a lease by this new definition and did not identify any new leases. Our lease agreements in which ASC Topic 842 has been applied are primarily for real estate properties, including retail branch locations, operations and administration locations and stand-alone ATM locations. We performed an analysis on equipment leases for the implementation of ASC Topic 842 and determined the number and dollar amount of our equipment leases was not material. ​ A modified retrospective transition approach is required, applying the new standard to all leases existing at the date of initial application. An entity may choose to use either (1) its effective date or (2) the beginning of the earliest comparative period presented in the financial statements as its date of initial application. We chose the transition method of adoption where we initially apply the new lease standard at the effective date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption if applicable. Therefore, we applied this standard to all existing leases as of the adoption date of January 1, 2019, recording a ROU asset and a lease liability in an equal amount. We recorded a ROU asset and lease liability of $82.2 million at the commencement date of January 1, 2019. We did not have a cumulative-effect adjustment to the opening balance of retained earnings at commencement and the adoption of ASC Topic 842 did not have a material impact on our consolidated income statement. ​ As of December 31, 2021 and 2020, we had operating ROU assets of $110.3 million and $113.4 million, respectively, and operating lease liabilities of $115.9 million and $118.3 million, respectively. We maintain operating leases on land and buildings for our operating centers, branch facilities and ATM locations. Most leases include one or more options to renew, with renewal terms extending up to 23 years. The exercise of renewal options is based on the sole judgment of management and what they consider to be reasonably certain given the environment today. Factors in determining whether an option is reasonably certain of exercise include, but are not limited to, the value of leasehold improvements, the value of renewal rate compared to market rates, and the presence of factors that would cause a significant economic penalty to us if the option is not exercised. Leases with an initial term of 12 months or less are not recorded on the balance sheet and instead are recognized in lease expense on a straight-line basis over the lease term. We do not sublease any portion of these locations to third parties. ​

​ As of December 31, 2021, the Company also holds a small number of finance leases assumed in connection to the CSFL merger completed in 2020. These leases are all real estate leases. Terms and conditions are similar to those real estate operating leases described above. Lease classifications from the acquired institutions were retained. At December 31, 2021, we do not maintain any leases with related parties, and we determined that the number and dollar amount of our equipment leases was immaterial. As of December 31, 2021, we have two additional operating leases that have not yet commenced of $22,000. These operating leases will commence in fiscal year 2022 with a lease term of 13 months. ​ See further discussion in Note 1—Summary of Significant Accounting Policies on page F-18 on accounting for leases.
