Loomis Sayles Core Plus Bond Fund
Actively managed U.S. bond fund
As of its 2026 Q2 report, Loomis Sayles Core Plus Bond Fund held 795 positions with $7.90B in net assets. Its ten largest holdings made up 22.4% of the fund. The NEFRX share class costs 0.73% a year. Over the 12 months to May 2026, NEFRX returned 5.8%, with dividends reinvested. In 2026 Q2 it added 98 new positions and exited 75.
The Fund seeks high total investment return through a combination of current income and capital appreciation.
The fund invests at least 65% of assets in investment-grade bonds across sectors and maturities, with the remainder in high-yield and non-dollar securities, selecting individual securities through macroeconomic analysis and fundamental credit assessment while maintaining duration within 2 years of the Bloomberg U.S. Aggregate Bond Index. Performance depends on the portfolio managers' security selection and sector positioning decisions. The fund may engage in active and frequent trading, which can generate short-term capital gains and increase transaction costs.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Bonds | 67.44% |
| Securitized | 33.22% |
| Cash & short-term | 2.88% |
| Derivatives | -0.01% |
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.

How it has done
NEFRX share class · total returns with dividends reinvested
Volatility over the last 12 months: 3.60%. Past returns are a record, not a forecast.
Jun 2026 has been filed since the trailing figures were struck, so it is 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 4 share classes hold the same portfolio
| Share class | Expense ratio | 1 year | 3 years | 5 years | Worst fall |
|---|---|---|---|---|---|
| 0.73% | +5.83% | +11.74% | +0.93% | -6.54% | |
| 1.48% | +5.08% | +9.29% | -2.82% | -6.82% | |
| 0.48% | +6.13% | +12.65% | +2.18% | -6.47% | |
| 0.39% | +6.20% | +12.94% | +2.66% | -6.42% |
These classes hold the same portfolio, so the 5.48pp spread over 5 years is the cost difference between them — roughly 1.10pp a year — not a difference in what they own.

Net is what a holder pays after the adviser's contractual waiver; gross is before it. A waiver can expire.
Turnover is how much of the portfolio was replaced in a year.

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 | 92.7% |
| Floating rate | 7.1% |
| Zero-coupon or unclassified | 0.3% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 1.6% |
| 1-3y | 8.7% |
| 3-5y | 14.7% |
| 5-10y | 24.9% |
| 10y+ | 50.1% |
Based on what filers reported; a filer that never reported a flag also reads as none.
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 a small fraction 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 | 75% |
| Credit spreads | 25% |
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 | +1.88 yr |
| High yield | +0.26 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 | 0.87 yr | 13% |
| 5 yr | 1.96 yr | 30% |
| 10 yr | 2.44 yr | 38% |
| 30 yr | 1.22 yr | 19% |
3 mo is NEGATIVE (-0.04 yr) — a deliberate hedge at that point on the curve, so it is not part of the band above.
| 3 mo | 0.01 yr | 0% |
| 1 yr | 0.23 yr | 11% |
| 5 yr | 0.85 yr | 40% |
| 10 yr | 0.70 yr | 33% |
| 30 yr | 0.35 yr | 16% |
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.

Dollar change per 1bp of spread movement, as filed and sign-anchored. A blank cell was not filed; a zero was.
Duration contribution in years, summing to the fund's 6.45 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.
