Quick answer

CMDRX was Columbia Short Term Bond Fund Advisor Class. At the close on November 22, 2024, those shares converted into Institutional Class shares, ticker NSTMX. Columbia removed Advisor Class references effective November 25, 2024.

The documented timeline

  • Before November 22, 2024: CMDRX identified the fund’s Advisor Class.
  • Close of business November 22, 2024: Advisor shares converted into Institutional shares.
  • November 25, 2024: Advisor Class references were removed from the summary prospectus.
  • Current SEC ticker data: NSTMX remains listed for the same fund series; CMDRX does not.

Same fund, different share class

Both tickers point to classes of Columbia Short Term Bond Fund. A share-class conversion changes the class held and its ticker; it does not mean one fund purchased another. Existing shareholders received Institutional Class shares through a transaction the prospectus described as tax-free.

The original CMDRX CUSIP was 19766B315. The current NSTMX Institutional Class uses CUSIP 19765H362. Account records should be reconciled using the conversion notice and broker or plan documentation, not inferred from quote sites.

What the underlying fund does

  • Objective in the 2024 prospectus: current income consistent with minimal fluctuation of principal.
  • Normally invests at least 80% of net assets in bonds.
  • Normally keeps at least 65% of total assets in investment-grade securities or unrated equivalents.
  • Can hold government, corporate, mortgage-backed, asset-backed, and dollar-denominated foreign debt, with a limited high-yield allocation.

How to verify the current class

  1. Open the SEC-filed August 2024 summary prospectus and read the conversion note beside CMDRX.
  2. Open Columbia’s current Institutional Class page for NSTMX.
  3. Match the fund series, full class name, ticker, and CUSIP.
  4. Review the newest prospectus for fees, eligibility, risks, and any later changes.
  5. Confirm account-specific availability with the brokerage or plan administrator.

Why old CMDRX pages still appear

Historical finance pages often remain online after a class closes or converts. The final $9.75 NAV observation on November 22, 2024 aligns with the prospectus conversion date. That history is useful, but it is not evidence that CMDRX remains available.

Continuation versus alternatives

NSTMX is the direct continuation for historical CMDRX holders. BSV, VCSH, SCHO, and FSHBX are separate products useful for comparison—not successor classes. Their management style, portfolio composition, trading mechanics, costs, and risks differ.
