Fund profile

As filed in the prospectus · 2026 Q1

The Ultra-Short Income Portfolio (the Fund) seeks current income with capital preservation while maintaining liquidity.

Strategy · summarised

The fund invests in high-quality, liquid money market instruments including commercial paper, bank debt, certificates of deposit, asset-backed securities, and government obligations, with all securities rated in the top two rating categories or equivalent. Under normal circumstances the fund maintains a maximum weighted average maturity of 90 days and weighted average life of 180 days. The fund pursues a fundamental policy of holding at least 25% of assets in financial services companies, though may temporarily hold less as a defensive measure. Because credit quality depends on ongoing assessment of issuer creditworthiness and the fund is not a money market fund, net asset value per share will fluctuate.

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.

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 a small fraction as much.

Interest-rate duration

approx. move per 100bp
Credit-spread duration
0.12 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 rates95%
Credit spreads5%

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.

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

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.
