Fund profile
As filed in the prospectus · 2026 Q2
The funds investment objective is to seek total return.
The fund pursues total return by allocating approximately 60% to equity securities and 40% to debt instruments, selecting stocks it believes are undervalued relative to intrinsic value and favoring large-cap companies, while investing substantially all debt holdings in investment-grade instruments. The manager employs active bottom-up fundamental analysis of individual issuers to drive security selection. Because security picks depend on the manager's analysis of individual companies and instruments, fund performance will diverge from any benchmark.

| C000007311 | 0.96% | 0.86% |
Net is what a holder pays after the adviser's contractual waiver; gross is before it. A waiver can expire.

Latest quarter
What changed since the fund's previous filing
Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to 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.
This fund changed legal form during the period shown. The history above is continuous — it spans both eras, and the change is not a gap in reporting.
Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-06-30
Share of the fund's debt by how its coupon behaves — the fact that decides whether a rate move reaches this portfolio at all.
| Fixed rate | 80.5% |
| Floating rate | 19.5% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 0.9% |
| 1-3y | 7.8% |
| 3-5y | 12.6% |
| 5-10y | 25.1% |
| 10y+ | 53.5% |
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.
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.
| Interest rates | 72% |
| Credit spreads | 28% |
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 the fund's spread duration carried by each credit tier.
| Investment grade | +0.90 yr |
| High yield | +0.05 yr |
Share of duration at each point, shortest first. A positive figure loses value when spreads widen; a negative one offsets — a credit hedge.
| 1 yr | 0.24 yr | 10% |
| 5 yr | 0.68 yr | 29% |
| 10 yr | 0.94 yr | 40% |
| 30 yr | 0.51 yr | 21% |
3 mo is NEGATIVE (-0.00 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.01 yr | 1% |
| 1 yr | 0.14 yr | 14% |
| 5 yr | 0.42 yr | 44% |
| 10 yr | 0.31 yr | 32% |
| 30 yr | 0.08 yr | 8% |
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.
