What this fund is
Objective, as filed

The Fund seeks to provide a high level of current income consistent with preservation of capital.

Strategy, summarised

The fund invests at least 80% of assets in investment-grade fixed-income securities, including corporate bonds, government debt, securitized products, bank loans, and foreign securities rated BBB- or higher. It maintains average portfolio duration within 25% of the Bloomberg US Aggregate Index. Because unrated securities are evaluated by the fund's own judgment rather than by external rating agencies, the credit quality of those holdings depends on the fund's assessment.

What the fund is made of

Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.

Bonds73.21%
Securitized25.08%
Cash & short-term1.23%

Derivatives-0.05%

The outer band is exposure held short — written against the portfolio rather than part of it, which is why it sits outside the ring and why the two are never netted into one figure.

Derivatives are shown at market value, not notional exposure.

Volatility over the last 12 months: 3.21%. Past returns are a record, not a forecast.

Jun 2026 and Jul 2026 have been filed since the trailing figures were struck, so they are not in the table above or the curve — every figure here shares one cut-off, which is what makes them comparable with other funds.

Turnover is how much of the portfolio was replaced in a year.

Risk profile

Interest-rate and credit-spread sensitivity, both in years · as of 2026Q2

Most of this fund’s sensitivity is to interest rates, with credit spreads carrying nearly as much.

5.79 yr
approx. move per 100bp
4.41 yr
approx. move per 100bp
If rates and spreads both rise 100bp

Where the loss would come from. The two shocks are the same size, so this is the balance of the fund's two sensitivities rather than a bet on one moving more.

of value
Interest rates57%
Credit spreads43%

Filers report the impact of a 0.01% move only, so the total is our own scaling of that one number and overstates the loss on most bonds — read it as approximate, never as precise. The two sensitivities overlap rather than add up: they measure the same positions against different shocks, which is why the durations above are shown side by side and never summed.

The two bands measure the same positions against different shocks and do not add — a Treasury carries rate duration and no spread duration, a floating-rate credit the reverse. Rate tenors are also summed across every currency the fund discloses.
