What this fund is
Objective, as filed

The Fund's investment objective is total return, comprised of current income and capital appreciation.

Strategy, summarised

The fund invests at least 80% of assets in investment-grade fixed-income securities—corporate bonds, U.S. Treasuries, agencies, and mortgage- and asset-backed securities—with a target dollar-weighted average maturity and duration under three years, using active duration and yield curve positioning relative to the Bloomberg 1-3 Year Government/Credit Index to generate alpha. The fund may hold up to 25% in foreign debt including emerging-market securities, up to 20% in below-investment-grade securities, and up to 20% in non-dollar currencies; it employs derivatives including swaps, futures, and options to adjust interest-rate and credit exposures. Because the fund does not track the index but instead makes active decisions on risk factors and security selection relative to it, portfolio composition and returns will diverge from the benchmark. The fund engages in active and frequent trading.

What the fund is made of

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

Cash & short-term6.28%

Look-through blends 3 underlying funds; 0.0% of NAV was not looked through and stays direct-classified.

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.

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.

1.95 yr
approx. move per 100bp
2.28 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.

≈ -4.0%
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.

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 and 10 yr are NEGATIVE (-0.07 yr, -0.04 yr) — a deliberate hedge at that point on the curve, so they are 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.
