Fund profile

As filed in the prospectus · 2026 Q1

The Funds investment objective is to seek to provide as high a level of current income as is consistent with preservation of capital through investment in bonds and other debt securities.

Strategy · summarised

The fund invests at least 80% of its net assets in investment-grade bonds issued by U.S. corporations, government entities, and government-sponsored enterprises, with up to 20% in high-yield debt and up to 25% in foreign debt securities; portfolio managers use fundamental and quantitative research alongside environmental, social and governance analysis to select holdings and may employ derivatives and duration management to hedge interest rate risk. Because security selection depends on the adviser's ESG assessment and valuation judgments, fund holdings will differ from any benchmark. The fund applies responsible investment criteria and may sell holdings if issuers do not operate consistently with those criteria.

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.

Return profile

Chart:

Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026

Share class1-year3-year5-yearVolWorst fall
+4.61%+14.33%+5.34%3.46%-5.21%

+4.80%+15.02%+6.39%3.53%-5.08%
+4.88%+15.26%+6.70%3.43%-5.00%

These classes hold the same portfolio, so the 5.52pp spread over 5 years is the cost difference between them — roughly 1.10pp a year — not a difference in what they own.

Cumulative return· Jul 2023 – Apr 2026

May 2026 and Jun 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.

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

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

Interest-rate duration

approx. move per 100bp
Credit-spread duration
2.19 yr

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.

≈ -8.5%
of value
Interest rates74%
Credit spreads26%

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.

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.

Rate exposure by currency

Duration contribution in years, summing to the fund's 6.14 yr.

USD+5.98 yr
DKK+0.31 yr
EUR-0.15 yr

This is where the fund's rate exposure sits, not its currency risk — most international bond funds hedge the currency back to dollars, and the size of those hedges is not in the filing. Tenors are also summed across curves, so a 5-year JPY point and a 5-year USD point are added together.
