Understanding the Incremental Borrowing Rate (IBR) under ASC 842
Under the ASC 842 lease accounting standard, a lessee is required to recognize a right-of-use (ROU) asset and a lease liability on the balance sheet for most leases. To calculate the present value of the lease payments, a discount rate must be applied.
What is the Incremental Borrowing Rate?
The ASC 842 standard specifies that the rate implicit in the lease should be used if it is "readily determinable." However, since this rate is often known only to the lessor, most lessees use their Incremental Borrowing Rate (IBR).
The IBR is defined as the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment.
How to Calculate the Lease Liability using IBR
The calculation follows the Present Value (PV) formula. Depending on whether payments are made at the beginning of the period (Advance) or the end (Arrears), the formula adjusts:
- Ordinary Annuity (Arrears): Used when payments occur at the end of the period.
- Annuity Due (Advance): Used when payments occur at the start of the period (common in commercial real estate).
Practical Example
Imagine a company enters a 5-year lease for office equipment with annual payments of $10,000. The company's IBR is determined to be 5%.
Scenario A (Arrears): The Lease Liability would be approximately $43,294.77.
Scenario B (Advance): Because the first payment is not discounted, the Lease Liability would be approximately $45,459.51.
Factors Influencing your IBR
- Credit Profile: The lessee's specific creditworthiness.
- Lease Term: The duration matches the borrowing term.
- Collateral: The rate must reflect a secured loan.
- Economic Environment: Current market rates and jurisdiction.
