CMDRX was the Advisor Class ticker for Columbia Short Term Bond Fund. On November 22, 2024, those shares converted into the fund’s Institutional Class, NSTMX. CMDRX is now a historical identifier.
CMDRX in plain English
A mutual fund owns a portfolio on behalf of shareholders. The same portfolio can be offered through multiple share classes that differ in eligibility, expenses, and distribution arrangements. CMDRX was one such class identifier; NSTMX identifies the Institutional Class that received the converted shares.
What the fund invested in
- U.S. government and agency debt
- Investment-grade corporate bonds
- Mortgage-backed and other asset-backed securities
- Dollar-denominated foreign debt
- A limited allocation to below-investment-grade bonds under the prospectus strategy
Objective and important limits
The 2024 prospectus described the objective as current income consistent with minimal fluctuation of principal. “Minimal fluctuation” did not mean guaranteed principal: the fund remained exposed to interest-rate, credit, prepayment, extension, liquidity, derivatives, and market risks, among others.
What a former holder should check
- Confirm that the old CMDRX position became NSTMX in account records.
- Review the current Institutional Class prospectus and eligibility rules.
- Check whether fees, waivers, or platform arrangements changed after conversion.
- Use the brokerage or plan administrator for cost-basis and transaction-history questions.
Where to find official information
Start with the SEC-filed conversion notice, then use the sponsor’s current NSTMX page and prospectus. The SEC’s current mutual fund ticker file provides a second check that NSTMX remains associated with the series while CMDRX no longer appears.
