Major challenges of the new lease accounting standards

Incremental Borrowing Rates

The new leasing standards require companies to use either 1) the interest rate implicit in the lease, or 2) the incremental borrowing rate (IBR) to calculate the lease liability. Determining the interest rate will likely be difficult for many companies, and so it’s expected that the IBR will be more widely used. However, understanding how to calculate the IBR may also be difficult.

Defining the IBR

The IBR is defined as the interest rate the lessee would have to pay to borrow the value of the asset over a similar term length and with similar security.

To calculate the IBR:

  • Determine the corporate borrowing rate and adjust if for security as well as any foreign currency adjustment.
  • If the company does not have a corporate borrowing rate, use a borrowing rate for an index the company is part of, or something similar, and adjust it for the company.

Treasury will be instrumental in this process as they will likely already hold some of the data needed tocalculate the IBR.
