To track the performance of the Bloomberg U.S. Aggregate Bond Index.
The fund seeks to track the Bloomberg U.S. Aggregate Bond Index through a stratified sample of investment-grade fixed-income securities selected by subadviser MetLife Investment Management. The sample is chosen to reflect the composite performance of the Index across U.S. Government securities, corporate debt, mortgage-backed securities, asset-backed securities, and other bonds included in the benchmark. Because the fund holds a sample rather than all Index constituents, its performance will diverge from the Index, and it may continue to hold securities no longer in the Index up to 20% of net assets.

What the fund is made of
Percentages are of fund net assets. Rounding, liabilities and short positions can make totals differ from 100%.
| Bonds | 73.59% |
| Securitized | 25.29% |
| Cash & short-term | 8.77% |
These positions come to 107.65% of the fund's net assets. This counts only what the fund reported holding — the holdings disclosure covers assets, not liabilities such as borrowings — so it is not expected to reconcile to 100%.

How it has done
C000017796 share class · total returns with dividends reinvested
Volatility over the last 12 months: 3.30%. 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.
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.

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 | 99.4% |
| Floating rate | 0.6% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 0.6% |
| 1-3y | 21.2% |
| 3-5y | 15.6% |
| 5-10y | 19.9% |
| 10y+ | 42.8% |
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 | +1.94 yr |
| High yield | +0.02 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 | 0.01 yr | 0% |
| 1 yr | 0.65 yr | 11% |
| 5 yr | 1.68 yr | 28% |
| 10 yr | 2.37 yr | 40% |
| 30 yr | 1.25 yr | 21% |
| 3 mo | 0.00 yr | 0% |
| 1 yr | 0.18 yr | 9% |
| 5 yr | 0.54 yr | 28% |
| 10 yr | 0.79 yr | 40% |
| 30 yr | 0.44 yr | 22% |
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.
