A lease provides the lessee the right to control the use of an identified asset for a period of time in exchange for consideration. Operating lease right-of-use assets (“ROU assets”) and lease liabilities are included in other assets and other liabilities on the Company's Condensed Consolidated Balance Sheets.

ROU assets represent the Company's right to use an underlying asset for the lease term and operating lease liabilities represent the Company's obligation to make lease payments arising from the lease. The Company determines if an arrangement is a lease at inception. ROU assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the lease term. Most operating leases contain renewal options that provide for rent increases based on prevailing market conditions. The lease term used to calculate the ROU asset includes any renewal options or lease termination that the Company expects to exercise.

The discount rate used to determine the commencement date present value of lease payments is the interest rate implicit in the lease, or when that is not readily determinable, the Company utilizes its secured borrowing rate. ROU assets include any lease payments required to be made prior to commencement and exclude lease incentives. Both ROU assets and lease liabilities exclude variable payments not based on an index or rate, which are treated as period costs. The Company's lease agreements do not contain significant residual value guarantees, restrictions or covenants.

The Company occupies office facilities under lease agreements that expire at various dates. In addition, office, production and transportation equipment is leased under agreements that expire at various dates. The Company does not have any significant finance leases.
