Fund profile

As filed in the prospectus · 2026 Q1

The Funds investment objective is to provide a high level of current income. The Funds secondary objectives are to seek growth of income and capital.

Strategy · summarised

The fund invests primarily in high-yield corporate bonds rated below investment grade, along with floating rate loans, preferred stocks, and other income-producing debt securities; the adviser and sub-advisers conduct their own credit analysis rather than relying primarily on ratings, and actively trade securities to improve yield and preserve capital. The fund may hold bonds in the lowest rating categories, including those in payment default or bankruptcy, and invests substantially in debt issued for leveraged transactions, creating significant credit risk. The fund may use short sales and derivatives, and may invest up to 25% in foreign and emerging market securities.

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 2026Q2

More of this fund’s sensitivity sits in credit spreads than in interest rates — a rate rally that comes with a credit selloff works against it.

Interest-rate duration
2.50 yr
approx. move per 100bp
Credit-spread duration
2.89 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
Credit spreads54%
Interest rates46%

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.
