How Bonds Can Enhance the ROA

Source: How Bonds Can Enhance the ROA

Given the volatility and uncertainty of the financial markets, bonds can provide Pension Plan Sponsors a strategy to mitigate some of that volatility. Bonds, through the certainty of their cash flows, prove to be a very effective tool. Most pensions focus on earning the return on asset (ROA) assumption as the goal of asset allocation. Because bonds yield less today than the ROA (7.00% average) the asset allocation to bonds tends to be lower than historic norms. But there exists a bond allocation that could enhance the probability of achieving the ROA. Here’s how:

1. Cash Flow Matching – if bonds were used to cash flow match and fund net liabilities (after contributions) chronologically they would produce the liquidity needed to fully fund such net liabilities. Cash flow matching works best with longer coupon bonds where you use semi-annual interest income to partially fund liabilities. A 10-year bond has 20 interest cash flows + one principal cash flowall priced at a 10-year yield. Having this liquidity wouldeliminate the need to do a cash sweep from other asset classes which is a common liquidity procedure. According to Guinness Global, the S&P 500 has 47% of its historical returns from dividends and reinvestment since 1940 on a 10-year rolling period basis. Wouldn’t you want to reinvest dividends back into growth assets rather than spend it on funding benefits + expenses? By using bonds as the liquidity assets, the growth assets are left unencumbered to grow. The longer the cash flow matching period, the more time the growth assets have to compound their growth. This strategy and practice could significantly enhance the ROA.

2. Yield on Bonds – the asset allocation models forecast the return of each asset class in the model, then weight each asset class to get the derived ROA for total assets. The ROA for most asset classes is based on the historical returns of each asset class index benchmark except for bonds. The currentyield on the bond index benchmark(s) is usually used as the forecast for bond returns. The Bloomberg Barclay Aggregate is most favored as the bond index benchmark. This index was designed at Lehman Bros. by Ron Ryan when he was the head of Fixed Income Research & Strategy from 1977 to 1983. The Aggregate is a very large and diversified portfolio of bonds with the following summary statistics as of March 31, 2025:

# of issues	13,770	Treasury	44.79%	AAA	3.06%
YTM	4.51%	Agency	1.29%	AA	47.86%
Duration	6.08 yrs.	Mtg. Backed	24.85%	A	11.38%
Avg. Maturity	8.38 yrs.	Corporates	24.06%	BBB	11.43%
				NR	25.60%

As a result, most asset allocation models would have a ROA for bonds of about 4.50%. If you can build a bond portfolio that outyields the Aggregate index, by definition, it should enhance the ROA for total assets. Ryan ALM Advisers, LLC has created a cash flow matching product we call the Liability Beta Portfolio™ (LBP). The LBP is a cost optimization model that cash flow matches liability cash flows chronologically at the lowest cost from a corporate bond portfolio skewed to A/BBB bonds. Based on the actuarial projections of each client we initially build a Custom Liability Index (CLI) to calculate net liabilities ((benefits + expenses) – contributions) chronologically. The CLI provides all the data needed for the LBP to function efficiently. Based on the allocation to the LBP will determine how far out the LBP can fully fund net liabilities. Usually, a 15% allocation to the LBP can fund 1-7 or even 1-10 years of net liabilities. The longer the term structure of the LBP, the higher the yield. The LBP will roughly outyield the Aggregate index by 50 bps (1-5 years) to over 100 bps (1-10 years) based on the LBP term structure. If the LBP outyields the AGG index by 50 to 100 bps, asset allocation can afford to overweight the bond allocation and still meet the target ROA for total assets. A 15% allocation to LBP is 7.5 to 15 bps value added to the ROA.

3.Cash – many pension plans have a cash allocation of around 2%+. Cash is usually the lowest yielding asset. Since the LBP becomes the liquidity assets to fully fund benefits + expenses chronologically, there is little need for cash to fund B+E. Cash might only be needed for capital calls on Private Equity and Alternative Investments. The LBP should significantly increase the yield margin versus cash since the LBP is using A/BBB+ coupon income from all maturities of the LBP. With the LBP fully funding B+E, the cash allocation can be reduced to <1%. Replacing most of the cash allocation to fund B+E with the LBP allocation is another ROA enhancement… it all adds up.

Most Asset Allocations for pensions are based on achieving the ROA. The ROA is an annual forecast of asset returns. Each asset class is assigned a ROA then weighted by the target allocation to get an average or target ROA. Currently, the ROA for most Public pensions is around 6.75%. This is in sharp contrast to the history of reported discount rates (ROA) for funding purposes as reported in the Milliman Public Funding Surveys.

Year	ROA (%)	Year	ROA (%)	Year	ROA (%)	Year	ROA (%)	Year	ROA (%)
2000	9.4	2005	8.3	2010	8.0	2015	7.7	2020	7.2
2001	9.3	2006	8.3	2011	7.8	2016	7.5	2021	7.0
2002	9.2	2007	8.2	2012	8.0	2017	7.5	2022	6.75E
2003	8.5	2008	8.1	2013	7.8	2018	7.3	2023	6.75E
2004	8.4	2009	8.1	2014	7.8	2019	7.3

Ryan ALM estimates for 2022 + 2023

As the Milliman Surveys show, the reported ROAs as discount rates for Public pension liabilities has trended downward from a high of 9.40% in 2000 to somewhere around 6.75% today. Corporate pensions are under ASC 715 discount rates (AA corporate zero-coupon yield curve) and have been reflective of market rates which are consistently much lower than the ROA discount rates. Plotting the ROA discount rates for Public pensions versus the history of 10-year Treasury rates (source: Ryan Treasury Indexes) shows that the yield difference is now at a 22-year low of around 283 basis points (as of 12/31/22). This trend would support a greater allocation to fixed income.

Ryan ALM Advisers uses and promotes A and BBB corporate bonds to cash flow match and defease clients projected liabilities. As a result, the yield spread versus the ROA gets even narrower. The current yield spreads for 10-year corporate bonds versus the 10-year Treasury are:

AA +56 bps

A +75 bps

BBB +114 bps

Using an average yield spread versus the 10-year Treasury for A/BBB corporate bonds = 95 basis points would narrow the ROA – Corporate Bond Yield Spread to 187 basis points. This suggests that fixed income can provide 72% of the target ROA. More importantly, using A/BBB corporate bond portfolio would outyield the BB Aggregate index (bond ROA) by around 75-100 basis points. The BB index YTW levels prove this point:

12/31/22 1/17/23

BB Aggregate = 4.68% 4.32%

BB Corporates = 5.42% 5.03%

Benefits of Higher Bond Allocation to Cash Flow Matching:

• Improve Liquidity

• Reduce Volatility (risk)

• Outyield Index Benchmark and bond ROA

• Create CORE portfolio as anchor to earning ROA

• Reduce costs to fund Benefits + Expenses (B + E)

• Buy TIME for performance assets to grow unencumbered
