Fund profile
As filed in the prospectus · 2025 Q3
Columbia Total Return Bond Fund (the Fund) seeks total return, consisting of current income and capital appreciation.
The fund invests at least 80% of its net assets in bonds and debt instruments across U.S. and non-U.S. governments, corporates, and mortgage- and asset-backed securities, with up to 35% in high-yield debt. It maintains an effective duration within +/- 2 years of the Bloomberg U.S. Aggregate Bond Index and may use derivatives including futures and swaps for hedging and to manage interest rate and credit exposure. The fund's frequent trading of portfolio securities and use of derivatives to adjust exposure mean returns will depend on the manager's tactical decisions rather than a fixed benchmark methodology.

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
| Securitized | 66.63% |
| Bonds | 29.15% |
| Cash & short-term | 9.45% |
| Loans | 5.30% |
| Stocks | 0.76% |
| Derivatives | -0.16% |
These positions come to 111.12% 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%.
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.
Sector allocation
The same holdings as Allocation above, grouped by market sector instead of asset type · as of 2026 Q2
| Securitized | 59.6% |
| Other | 10.9% |
| Cash | 8.4% |
| Government | 4.4% |
| 12 smaller | 16.7% |
Government, Securitized and Cash are non-corporate buckets; International is foreign holdings we don’t sector-classify, and Other is the residual (held funds, unresolved names).

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 | 63.1% |
| Floating rate | 36.8% |
| Zero-coupon or unclassified | 0.1% |
Share of the fund's debt value in each maturity band, shortest first.
| <1y | 1.3% |
| 1-3y | 5.6% |
| 3-5y | 8.3% |
| 5-10y | 22.8% |
| 10y+ | 61.9% |
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 | 58% |
| Credit spreads | 42% |
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 | +3.46 yr |
| High yield | +1.08 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 | 0.07 yr | 1% |
| 1 yr | 0.59 yr | 9% |
| 5 yr | 1.86 yr | 30% |
| 10 yr | 2.52 yr | 40% |
| 30 yr | 1.24 yr | 20% |
| 3 mo | 0.26 yr | 6% |
| 1 yr | 0.19 yr | 4% |
| 5 yr | 0.85 yr | 19% |
| 10 yr | 0.72 yr | 16% |
| 30 yr | 2.51 yr | 55% |
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 6.28 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.
