(1) The rates implicit in the Company’s leases are not readily determinable. Therefore, the Company uses its incremental borrowing rate as the discount rate when measuring operating lease liabilities. The incremental borrowing rate represents an estimate of the interest rate the Company would incur to borrow an amount equal to the lease payments on a collateralized basis over the lease term in a similar economic environment.
