Pension Curve Insider: LDI Solutions November Monthly Recap
Monthly Recap
Intermediate-term Treasury yields rose during the month of November, while corporate spreads remained stable through the month. The discount rates for a sample plan liability declined by 4 basis points for both the AA-rated spot curve and the top-yielding curve.
Plan liability values increased slightly on a marked-to-market basis, extending their increase from the prior month. Spreads widened marginally, and the top-yielding curve provided 36 basis points of additional yield at month end versus the broader AA-rated universe.
Issuance for the month of November totaled $8.4B, a similar volume to the previous month. New issues had a minor upward impact on the short to intermediate segments of the curve. No turnover occurred due to credit rating changes, and only one bond exited the universe.

Glossary
IRS Yield Curve: Plan sponsors of qualified defined benefit pension plans use this yield curve to determine funding requirements per IRS regulations. These funding requirements are disclosed on form 5500 annually. Yields on AAA, AA, and A corporate securities determine the yield curve for discounting purposes. The yield curve is not a marked-to-market curve representing any single date, but rather an average yield over the course of the entire month. For more information on the IRS methodology, please see treasury.gov/resource-center and irs.gov/Retirement-Plans.
Accounting Yield Curve: US GAAP requires pension plan sponsors to disclose pension obligations using “fixedincome debt securities that receive one of the two highest ratings given by a recognized ratings agency”. As a proxy for bonds useable for accounting purposes, we use the constituents of BBgBarc AA credit universe to develop the accounting yield curve shown. Please see fasb.org for more information.
Top Yielding Curve: Since the US GAAP rules allow the use of a fairly broad range of securities for accounting purposes, some plan sponsors use an optimized yield curve approach to value their pension liabilities on the disclosure dates. Bonds trading at higher yields than other bonds of similar maturity tend to be used for this purpose. To quantify the effectiveness of this approach, T. Rowe Price developed a yield curve using the highest yielding bonds designed to meet SEC requirements at each node.
Annual Tracking Error Relative to Liability: Calculated as the standard deviation of return differences between a fixed income index and a set of cash flows discounted using the accounting yield curve. The liability return has two components: an interest cost component analogous to roll return on a bond, and yield change component analogous to price return on a bond. The table shows annualized ex-post tracking error.
Average Monthly Return Difference: Similar to the tracking error metric, this metric demonstrates how closely a fixed income benchmark tracks a set of liability returns. We calculate this measure by simply averaging the difference in returns over the period shown.
Sample Plan Liability: Pension plan sponsors must account for the cost of their retirement plan on their financial statements. The amount of this liability can fluctuate over time based on several factors, including benefits earned, benefits paid out, mortality experience, and most significantly, interest rates. The Sample Plan is intended to be a representative defined benefit pension plan and does not reflect the cash flows from any specific plan.
