The systematic active fixed income (SAFI) intermediate fixed income strategy can help sponsors improve funded-ratio risk management, diversify alpha sources, and better align hedging assets with maturing liabilities.
Our Systematic US High Quality Intermediate strategy combines intermediate-duration liability relevance with a systematic, benchmark-aware process designed to complement traditional fundamental active credit managers. It can play several roles for DB hedging, as follows:
SAFI Intermediate addresses investor goals to maintain funded status with increased customization flexibility, lower tracking risk, low cost, and strong performance potential.
Corporate defined benefit plan sponsors are entering a new phase of pension risk management. Funded ratios are still meaningfully elevated at 109.5%,1 as plans have benefited from stronger asset returns, higher discount rates relative to the post-financial crisis period, and disciplined de-risking programs. Meanwhile, many plans are frozen or closed. As benefit accruals decline, liability cash flows mature and plan duration often shortens. Sponsors therefore need a more balanced mix of long, intermediate, and cash-flow-aware hedging assets.
Against this backdrop, objectives have shifted from earning out of deficits and growing, to preserving surplus, reducing funded-ratio volatility, and maintaining end-state optionality. This has raised the importance of hedge quality. Sponsors need fixed income portfolios that are more precisely aligned with their liability duration, spread exposure, cash flows, liquidity needs, and governance objectives.
Corporate bonds remain DB plans’ primary liability-hedging asset because they provide exposure to the interest-rate and credit-spread risks embedded in pension liabilities. SAFI may improve hedge quality in several ways:
As plans have de-risked, active credit managers have become central to hedge portfolios. Many active credit managers rely on similar fundamental research processes and may express comparable issuer, sector, quality, liquidity, and spread-risk preferences. Their excess returns can become correlated, especially during stress periods (Figure 1).
For a DB sponsor, correlated alpha is a funded-ratio risk:if multiple managers underperform at the same time, the hedge portfolio can experience alpha drawdowns precisely when funded-status protection is most valuable.

At the same time, liability duration is changing. As plans freeze, close, and mature, cash flows shift closer to the present and duration declines. This makes intermediate fixed income a more central element of the hedging portfolio. Intermediate mandates can serve as a lower-duration hedge for mature liabilities, a liquidity sleeve for benefit payments, a middle ground between core bond assets and long-duration LDI, or a completion tool alongside long credit and Treasuries.
The opportunity gap is not due to a lack of securities; intermediate credit offers a broad issuer set. The gap is that the institutional LDI ecosystem has historically been more developed around long-duration mandates than differentiated intermediate active solutions. SAFI Intermediate can support hibernation, retention, partial risk transfer, or broader LDI customization.
If the strategy can deliver competitive excess return with low tracking error, lower fees, and lower alpha correlation, it can improve the trade-off between expected return, drawdown risk, and cost.
In this illustrative analysis, adding SAFI Intermediate improved hedge quality by reducing tracking error from 66 basis points (bps) to 55bps, and lowering the 95th percentile drawdown from $17 million to $12 million. It also reduced the probability of falling below a 99% funded ratio over both one and three years, while maintaining the same expected funded ratio.

SAFI Intermediate should be evaluated as part of the total hedge portfolio rather than as an isolated manager search. Sponsors can model it as a partial replacement for fundamental active credit or as a new allocation funded from passive intermediate credit, with the comparison focused on funded-ratio volatility, expected excess return, alpha drawdown, managerstyle concentration, liquidity, and net cost. Rather than adding another credit allocation driven by discretionary issuer research, SAFI Intermediate brings a systematic implementation approach to high-quality corporate bonds, one that uses the potential return benefits of factor signals such as value, momentum, and sentiment.
This creates a differentiated alpha source. SAFI Intermediate can evaluate a broad universe consistently, apply disciplined risk controls, and target active risk where compensation appears most attractive, making it complementary—not redundant—to traditional fundamental managers (Figure 2). Intermediate-duration exposure can better match maturing liabilities and reduce reliance on long credit where it is less appropriate.

As of June 30, 2026, the strategy generated positive net excess return versus the Bloomberg Intermediate Corporate ex-Baa Index: 35 basis points over one year and 54 basis points annualized since inception of the SAFI process. These results were achieved with low realized tracking error of 0.13% over one year and 0.26% since inception.
