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.
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.

How it has done
EVIBX share class · total returns with dividends reinvested
Volatility over the last 12 months: 2.35%. Past returns are a record, not a forecast.
Jun 2026 and Jul 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.
The 5 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.96% | +6.19% | +26.28% | +23.76% | -2.42% | |
| 1.71% | +5.61% | +23.47% | +19.41% | -2.33% | |
| 1.21% | +5.94% | +25.30% | +22.43% | -2.25% | |
| 0.71% | +6.45% | +26.96% | +25.35% | -2.38% | |
| 0.62% | +6.75% | +27.54% | +26.16% | -2.36% |
These classes hold the same portfolio, so the 6.75pp spread over 5 years is the cost difference between them — roughly 1.35pp a year — not a difference in what they own.

Debt profile
What this fund holds — value-weighted across its bond and securitized long positions · as of 2026-04-30
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 | 89.2% |
| Floating rate | 10.2% |
| Zero-coupon or unclassified | 0.6% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 0.9% |
| 1-3y | 17.0% |
| 3-5y | 39.7% |
| 5-10y | 40.3% |
| 10y+ | 2.1% |
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.
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.
| Credit spreads | 54% |
| Interest rates | 46% |
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.
| High yield | +2.72 yr |
| Investment grade | +0.17 yr |
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 | 0.04 yr | 2% |
| 1 yr | 0.72 yr | 29% |
| 5 yr | 1.36 yr | 54% |
| 10 yr | 0.29 yr | 12% |
| 30 yr | 0.09 yr | 3% |
| 3 mo | 0.04 yr | 1% |
| 1 yr | 0.80 yr | 28% |
| 5 yr | 1.63 yr | 56% |
| 10 yr | 0.34 yr | 12% |
| 30 yr | 0.07 yr | 3% |
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.
