Fund profile
As filed in the prospectus · 2025 Q4
Multi-Manager Total Return Bond Strategies Fund (the Fund) seeks total return, consisting of capital appreciation and current income.
Columbia Management allocates the fund's assets among multiple subadvisers, each managing a separate sleeve using different investment styles and processes to pursue total return from bonds and debt securities. The fund invests at least 80% of assets in bonds and other debt instruments, including government, corporate, mortgage-backed, asset-backed, and foreign debt securities, with up to 20% permitted in below-investment-grade securities and up to 25% in foreign investments. The fund may use derivatives including futures, swaps, options, and forwards to hedge positions, increase exposure, and manage duration and yield curve. Because returns depend on the subadvisers' security selections and the complementary nature of their different styles, performance will diverge from any single investment approach.

Allocation
Asset groups · long / short shown separately, never netted · 2026 Q1
| Securitized | 50.79% |
| Bonds | 44.10% |
| Cash & short-term | 14.75% |
| Loans | 0.49% |
| 2 smaller | 0.12% |
These positions come to 110.25% 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%.
Derivatives are shown at market value, not notional exposure.

Return profile
Total return as filed — price change plus distributions reinvested · trailing figures to Feb 2026
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 2026-02-28
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 | 79.7% |
| Floating rate | 19.7% |
| Zero-coupon or unclassified | 0.6% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 1.1% |
| 1-3y | 9.0% |
| 3-5y | 12.1% |
| 5-10y | 16.4% |
| 10y+ | 61.4% |
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 2026Q1
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 | 61% |
| Credit spreads | 39% |
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 | +3.33 yr |
| High yield | +0.35 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 | 0.05 yr | 1% |
| 1 yr | 0.62 yr | 11% |
| 5 yr | 1.70 yr | 29% |
| 10 yr | 2.30 yr | 39% |
| 30 yr | 1.17 yr | 20% |
| 3 mo | 0.35 yr | 9% |
| 1 yr | 0.08 yr | 2% |
| 5 yr | 0.64 yr | 17% |
| 10 yr | 1.00 yr | 27% |
| 30 yr | 1.62 yr | 44% |
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 5.83 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.
