Fund profile
As filed in the prospectus · 2026 Q2
The Fund seeks to provide income with a
The fund invests in fixed-income securities selected by Loomis Sayles' credit research team for attractive valuations relative to assessed credit risk, with at least 55% in investment-grade bonds and up to 35% in below-investment-grade securities. The manager also seeks securities whose prices respond more to issuer-specific events than to interest rate or market-wide default movements, and analyzes yield spreads across sectors and geographies to identify relative value. The fund may hold up to 40% in foreign securities and employs derivatives including credit default swaps to manage risk and enhance returns. Because security selection depends on the manager's credit assessments and relative-value judgments, fund performance will diverge from any benchmark.

|---|---|---|
| LSBDX | 0.71% | 0.64% |
| LSBRX | 0.96% | 0.89% |
| LBFAX | 1.20% | 1.14% |

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

Allocation
Asset groups · long / short shown separately, never netted · 2026 Q2
| Bonds | 72.83% |
| Securitized | 16.73% |
| Loans | 7.47% |
| Cash & short-term | 3.65% |
| Stocks | 0.47% |
| Derivatives | -0.07% |
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.
Derivatives are shown at market value, not notional exposure.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Apr 2026
| Share class | 1-year | 3-year | 5-year | Vol | Worst fall |
|---|---|---|---|---|---|
| +6.52% | +22.17% | +13.87% | 3.56% | -4.99% | |
| +6.20% | +21.23% | +12.43% | 3.51% | -5.08% | |

| +6.58% | +22.38% | +14.19% | 3.56% | -5.07% |
These classes hold the same portfolio, so the 3.03pp spread over 5 years is the cost difference between them — roughly 0.61pp a year — not a difference in what they own.
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.
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 | 84.5% |
| Floating rate | 14.2% |
| Zero-coupon or unclassified | 1.3% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 6.1% |
| 1-3y | 5.5% |
| 3-5y | 27.6% |
| 5-10y | 34.4% |
| 10y+ | 26.4% |
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 nearly 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 | 53% |
| Credit spreads | 47% |
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 | +2.98 yr |
| High yield | +1.07 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 | 0.53 yr | 11% |
| 5 yr | 3.90 yr | 84% |
| 10 yr | 0.15 yr | 3% |
| 30 yr | 0.06 yr | 1% |
3 mo is NEGATIVE (-0.05 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.02 yr | 1% |
| 1 yr | 0.41 yr | 10% |
| 5 yr | 1.55 yr | 38% |
| 10 yr | 1.63 yr | 40% |
| 30 yr | 0.43 yr | 11% |
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.
