Fund profile

As filed in the prospectus · 2026 Q2

The Fund seeks high total investment return through a combination of current income and capital appreciation.

Strategy · summarised

The fund invests at least 80% of assets in investment-grade fixed-income securities selected by the adviser based on improving credit profiles, issuer-specific rather than market-driven price sensitivity, and attractive yield spreads relative to risk; it may hold up to 15% in below-investment-grade bonds and up to 30% in dollar-denominated foreign securities. The fund's returns depend on the adviser's security selection and credit analysis rather than tracking an index. The adviser may also use derivatives, bank loans, mortgage-backed securities, and structured notes to implement its strategy.

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.

Cumulative return· Apr 2023 – Feb 2026

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

These three overlap — one holding can be in arrears and paying in kind at once — so they are shown separately and never summed.

Risk profile

Interest-rate and credit-spread sensitivity, both in years · as of 2026Q1

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

Interest-rate duration
6.14 yr
approx. move per 100bp
Credit-spread duration
4.18 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.

≈ -10.5%
of value
Interest rates60%
Credit spreads40%

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.

Where the risk sits on the curve

Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.

3 mo is NEGATIVE (-0.02 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.

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.
