Recent Accounting Standards Not Yet Effective Leases In February 2016, the FASB issued an accounting standards update on financial reporting for leasing arrangements, including requiring lessees to recognize an operating lease with a term greater than one year on their balance sheets as a right-of-use (ROU) asset and corresponding lease liability, measured at the present value of the lease payments.
