Financial Reporting Alert 16-4, Financial reporting considerations related to pension and other postretirement benefits

This publication highlights some of the important accounting considerations related to the calculations and disclosures entities provide under U.S. GAAP in connection with their defined benefit pension and other postretirement benefit plans.

Discount Rate

Over the past few years, we have provided insights into approaches used to support discount rates for defined benefit plans (e.g., hypothetical bond portfolio, yield curve, index-based discount rate), as well as considerations related to how the discount rates should be applied when an entity measures its benefit obligation. Over the past year and a half, the most discussed emerging issue related to discount rates for defined benefit plans is the use of a more granular approach to measure components of benefit cost. Considerations related to an entity’s discount rate selection method, its use of a yield curve, and its measurement of components of benefit cost are addressed below.

Discount Rate Selection Method

ASC 715-30-35-43 requires the discount rate to reflect rates at which the defined benefit obligation could be effectively settled. In the estimation of those rates, it would be appropriate for an entity to use information about rates implicit in current prices of annuity contracts that could be used to settle the obligation. Alternatively, employers may look to rates of return on high-quality fixed-income investments that are currently available and expected to be available during the benefits’ period to maturity.

One acceptable method of deriving the discount rate would be to use a model that reflects rates of zero-coupon, high-quality corporate bonds with maturity dates and amounts that match the timing and amount of the expected future benefit payments. Since there are a limited number of zero-coupon corporate bonds in the market, models are constructed with coupon-paying bonds whose yields are adjusted to approximate results that would have been obtained through the use of the zero-coupon bonds. Constructing a hypothetical portfolio of high-quality instruments with maturities that mirror the benefit obligation is one method that can be used to achieve this objective. Other methods that can be expected to produce results that are not materially different would also be acceptable — for example, use of a yield curve constructed by a third party such as an actuarial firm. The use of indexes may also be acceptable.

Editor’s Note

In determining the appropriate discount rate, entities should consider the following SEC staff guidance (codified in ASC 715-20-S99-1):

At each measurement date, the SEC staff expects registrants to use discount rates to measure obligations for pension benefits and postretirement benefits other than pensions that reflect the then current level of interest rates. The staff suggests that fixed-income debt securities that receive one of the two highest ratings given by a recognized ratings agency be considered high quality (for example, a fixed-income security that receives a rating of Aa or higher from Moody’s Investors Service, Inc.).

Entity’s Use of a Yield Curve

To support its discount rate, an entity may elect to use a yield curve constructed by an actuarial firm or other third party. Many yield curves constructed by actuarial firms or other third parties are supported by a white paper or other documentation that discusses how the yield curves are constructed. Management should understand how the yield curve it has used to develop its discount rate was constructed as well as the universe of bonds included in the analysis. If applicable, management should also evaluate and reach conclusions about the reasonableness of the approach the third party applied to adjust the bond universe used to develop the yield curve.

We have been advised by some third parties, particularly those constructing yield curves for non-U.S. markets (e.g., the eurozone and Canada), that because of a lack of sufficient high-quality instruments with longer maturities, they have employed a method in which they adjust yields of bonds that are not rated AA by an estimated credit spread to derive a yield representative of an AA-quality bond. This bond, as adjusted, is included in the bond universe when the third party constructs its yield curve. Management should understand the adjustments made to such bond yields in the construction of those yield curves and why those adjustments are appropriate.

Measurement of Interest Cost Component

In the current year, the most discussed emerging issue related to discount rates is the alternatives for applying discount rates under a bond-matching approach (sometimes also referred to as a hypothetical bond portfolio or bond-model approach). In light of the SEC staff’s recent acceptance of the use of a spot rate approach for measuring interest cost by entities that develop their discount rate assumption by using a yield curve approach, entities and actuaries have been exploring whether other acceptable methods similar to the spot rate approach could be developed for entities that use a bond-matching approach to measure their defined benefit obligation. Specifically, the alternative approach focuses on measuring the interest cost component of net periodic benefit cost by using individual spot rates derived from an acceptable high-quality corporate bond yield curve and matched with separate cash flows for each future year.

During the spring and early summer of 2016, representatives of the Big Four accounting firms and a large actuarial firm engaged in discussions with the SEC staff regarding the viability of a similar granular approach to measure interest cost for registrants that use a bond-matching approach to support the discount rate. In an August 2, 2016, meeting, the SEC staff stated that it objected to the approach presented because of the following factors:

  • The staff’s overall concern is that using such derived spot rates to measure interest cost on the defined benefit obligation could not be demonstrated, at each maturity, to be based on the same rates inherent in the measurement of the defined benefit obligation under the bond-matching approach (i.e., the spot rates inherent in the bond portfolio are not observable). Therefore, the proposed approach would fail to comply with ASC 715-30-35-8, which requires entities to use the same interest rates to measure the defined benefit obligation and interest cost.
  • The staff also expressed concern that the derived spot rates in the proposed approach would be inconsistent with the reinvestment-rate assumption used in the cash flow matching process that is part of building the cash flow matched hypothetical bond portfolio used to measure the defined benefit obligation under a bond-matching approach.

Editor’s Note

We believe that in the absence of entity-specific changes in facts and circumstances, it could be challenging to justify or support a change from a bond-matching approach to a yield curve approach. Historically, entities have generally made the switch only from a yield curve approach to a bond-matching approach, which suggests that of the two methods, the bond-matching approach results in a better estimate. This historical practice, along with the SEC staff’s position that the acceptability of the spot rate approach would not by itself be a change in facts and circumstances that justifies a change in approach to selecting discount rates, reduces the likelihood that switching from a bond-matching approach to a yield curve approach would be considered a better estimate in accordance with the best-estimate objective of ASC 715.
