Leases (Policies)	3 Months Ended

Leases [Abstract]
Leases	The Corporation has committed to rent premises used in business operations under non-cancelable operating leases and determines if an arrangement meets the definition of a lease upon inception. The Corporation adopted the provisions of ASU 2016-02 (Topic 842) on January 1, 2019. Operating lease right-of-use (“ROU”) assets represent a right to use an underlying asset for the contractual lease term. Operating lease liabilities represent an obligation to make lease payments arising from the lease. Upon adoption, operating lease ROU assets totaling $28.9 million and operating lease liabilities totaling $30.9 million were recognized in our Unaudited Consolidated Balance Sheets for leases that existed at the adoption date, based on the present value of lease payments over the remaining lease term. Operating leases entered into after the adoption date will be recognized as an operating lease ROU asset and operating lease liability at the commencement date of the new lease. The Corporation’s leases do not provide an implicit interest rate, therefore the Corporation used its incremental collateralized borrowing rates commensurate with the underlying lease terms to determine the present value of operating lease liabilities. The weighted average discount rate used to discount operating lease liabilities at March 31, 2019 was 3.66%. The Corporation’s operating lease agreements contain both lease and non-lease components, which are generally accounted for separately. The Corporation’s lease agreements do not contain any residual value guarantees. Operating leases with terms of 12 months or less are included in ROU assets and operating lease liabilities recorded in our Unaudited Consolidated Balance Sheets. Operating lease terms include options to extend when it is reasonably certain that the Corporation will exercise such options, determined on a lease-by-lease basis. As of March 31, 2019, the Corporation does not have any leases that have not yet commenced. At March 31, 2019, lease expiration dates ranged from 2 months to 22 years, with additional renewal options on certain leases ranging from 1 to 5 years. At March 31, 2019, the weighted average remaining lease term for the Corporation’s operating leases was 14.4 years. Rental expense for operating leases is recognized on a straight-line basis over the lease term and amounted to $939 thousand and $916 thousand, respectively, for the three months ended March 31, 2019 and 2018. Variable lease components, such as fair market value adjustments, are expensed as incurred and not included in ROU assets and operating lease liabilities.
