Market Environment
First quarter 2025 may have been the calm before the storm. Treasury rates declined across the yield curve as concerns about muted growth prospects emerged due to indications the U.S. government planned to introduce protectionist trade policies. These concerns impacted investor predictions for forward-looking Fed interest rate decisions, indicating one additional Fed rate cut was expected and bringing the tally of expectations to four cuts by year end. The next Fed decision is scheduled for May 7th, and investors predict no change to the federal funds rate at that meeting.
The Bloomberg U.S. Aggregate Index returned 2.8% during the first quarter as interest rates declined and credit spreads widened modestly from a low base. Riskier market segments underperformed high-quality bonds. The Bloomberg U.S. Corporate High Yield Index returned 1.0%, and the S&P 500 Index returned -4.3%. All major credit segments of the Bloomberg U.S. Aggregate Index had negative excess returns during the quarter.
Credit issuance remained robust during the quarter, with issuers refinancing short maturities amid low credit spreads, muted volatility, and strong demand. High-grade corporate bond issuance increased 19% while high yield issuance (bonds plus loans) was flat year over year. Asset-backed securities (ABS) issuance was flat, but nontraditional ABS volumes increased 10% from 2024’s pace. Commercial mortgage-backed securities (CMBS) volumes jumped 139% off a lower base year over year. Net issuance was modest but positive in all credit sectors.
With spreads wider and positive net issuance, opportunities are emerging in pockets of the market. The percentage of credits that screened as a “buy” increased to 11% from 4% for investment-grade corporate bonds and to 38% from 16% for high yield corporate bonds. The percentage of loans screening as a “buy” decreased though to 45% from 58%. Within the investment-grade corporate credit market, interest rate-sensitive sectors like life insurance, finance companies, and banks continue to screen attractively, while opportunities are also emerging in consumer cyclical companies. Tariff pressures should have a greater effect on more leveraged businesses in the high yield market, which drove credit spreads toward more appropriate ranges.
Away from credits in mainstream indexes, spreads in some ABS subsectors increased toward their long-term averages. Most nontraditional ABS continue to screen attractively in our valuation framework and offer appealing yield prospects. Data center ABS spreads widened from very low levels as concerns over long-term data center demand arose from artificial intelligence (AI) efficiency improvements and potential tariffs. CMBS spreads in select opportunities remain disconnected from their credit profiles, as property-level dynamics remain imperative for performance.
Valuations
Valuations are not yet broadly attractive, and caution is still warranted in several areas of the market. Agency mortgage-backed securities (MBS) valuations remain broadly unattractive as spreads compressed further, with no cohort of the 15- or 30-year MBS market screening as a “buy” candidate. Negative excess returns remain possible for most of the investment-grade corporate bond universe. Less than half of the high yield corporate bond and loan markets screen attractively, highlighting the importance of a selective approach. Spreads on collateralized loan obligation (CLO) debt widened from very narrow levels to below-average levels. Emerging market credits remain unappealing due to concerns over creditor rights in most countries and its impact on their durability, compounded with the uncertainties that tariffs may impose on supply chains. We believe nonagency residential mortgage-backed securities (RMBS) remain plagued by poor issuance trends, unattractive valuations, and weak fundamentals.
Valuations reflect a growing belief that the U.S. economy is slowing. GDP estimates declined and suggested a recession is possible. Changing global tariff policies have weighed on business and consumer sentiment while also driving concerns about inflation.
Credit performance of business loans have been strong, although recent tariff policies may challenge future credit performance. Defaults trended lower, while recoveries improved. U.S. business bankruptcies remain low, and business loans held at banks are performing well. There has been an increase in pay-in-kind (PIK) interest for loans held in some private credit structures. We are monitoring the increase in PIK loans closely to distinguish between unique borrower business models vs. inabilities to service debt.
Performance
- The portfolio gained during the quarter but lagged its benchmark.
- The portfolio’s sector and rating emphases detracted modestly to relative results during the quarter, but experienced favorable selection results across positions in ABS, loans, CMBS, and high yield corporate bonds.
- Holdings of loans to electric utility companies, high yield bonds of technology companies, and CLOs impacted selection results positively.
- Investment-grade corporate bonds issued by banks and life insurers had a small but negative impact on selection results.
Transaction Summary
We continued to find durable credits offering attractive value even as valuations reflect a growing belief that the U.S. economy is slowing. The table below summarizes a few notable portfolio additions.
Characteristics
- At the end of the quarter, the portfolio’s duration was 0.9 years, consistent with our objective of preserving capital.
- The portfolio’s yield to maturity was 5.3% and remained elevated vs. short-term bond market alternatives.
- Over the quarter, the portfolio’s weight to ABS and investment-grade corporate bonds marginally increased while reserves decreased to 21% from 27%, and the portfolio held 5% in high yield and nonrated credit instruments, similar to last quarter’s level.
Concluding Remarks
Uncertainty over tariffs is already having a recessionary impact on business activity and could pressure the performance of many industries and companies. We remain steadfast in our approach, focusing on identifying durable credits1 – those that can withstand the worst environments faced by their issuer’s industries – at attractive yields. We do this by evaluating individual opportunities bottom-up and not allowing top-down sentiments to alter the application of this approach. We believe this decision-making structure serves our clients well in all environments, whether markets are calm and complacent or volatile and uncertain.

The securities do not represent all of the securities purchased, sold, or recommended for advisory clients and you should not assume that investments in the securities were or will be profitable.
Issuers with credit ratings of AA or better are considered to be of high credit quality, with little risk of issuer failure. Issuers with credit ratings of BBB or better are considered to be of good credit quality, with adequate capacity to meet financial commit¬ments. Issuers with credit ratings below BBB are considered speculative in nature and are vulnerable to the possibility of issuer failure or business interruption.

Risks
Investing in the bond market is subject to certain risks including market, interest-rate, issuer, credit, maturity, call and infla¬tion risk; investments may be worth more or less than the original cost when redeemed. Bond prices are sensitive to changes in interest rates and a rise in interest rates can cause a decline in their prices. Mortgage-backed securities have prepayment, extension, and interest rate risks.
Asset-Backed Securities (“ABS”) are subject to risks due to defaults by the borrowers; failure of the issuer or servicer to perform; the variability in cash flows due to amortization or acceleration features; changes in interest rates which may influence the pre¬payments of the underlying securities; misrepresentation of asset quality, value or inadequate controls over disbursements and receipts; and the ABS being structured in ways that give certain investors less credit risk protection than others. Below invest¬ment grade bonds, commonly known as junk bonds, are subject to a high level of credit and market risks.
SASB lacks the diversification of a transaction backed by multiple loans since performance is concentrated in one commercial property. SASBs may be less liquid in the secondary market than loans backed by multiple commercial properties.
The Strategy invests in derivative instruments, investments whose values depend on the performance of the underlying secu¬rity, assets, interest rate, index or currency and entail potentially higher volatility and risk of loss compared to traditional bond investments.
Foreign investing involves special risks including currency risk, increased volatility, political risks, and differences in auditing and other financial standards. Prices of emerging market securities can be significantly more volatile than the prices of securities in developed countries, and currency risk and political risks are accentuated in emerging markets.
The Strategy may engage in certain investment activities that involve the use of leverage, which may magnify losses.
A significant investment of assets in one or more sectors, industries, securities and/or durations may increase its vulnerability to any single economic, political, or regulatory developments, which will have a greater impact on returns. Illiquid investments subject the investor to the risk that she may not be able to sell the investments when desired or at favorable prices.
Portfolio Characteristics are of the Representative Account. The Representative Account is managed with the same investment objectives and employs substantially the same investment philosophy and processes as the Strategy.
