Risks
Past performance is not a guide to future returns and the Fund may not achieve its investment objective. Your capital is at risk. The value of investments can fall as well as rise and investors might not get back the sum originally invested. The rate of return at which interest and principal repayments from fixed income securities are reinvested will be lower in a falling interest rate environment. Credit ratings issued by credit rating agencies cannot be relied upon to be fully up-to-date or fully reflect the true risks of an investment. The income and capital due from asset-backed securities are dependent upon their ability to pay and any default may adversely affect the value of your investment. All the risks currently identified as being applicable to the Fund are set out in the “Special Considerations and Risk Factors” section of the Prospectus.
Investment approach
The Columbia Threadneedle US Asset-Backed Securities Fund is designed to deliver consistent, attractive returns through a disciplined focus on high-quality, liquid US securitised assets.
We believe the US securitised credit market offers compelling opportunities for institutional investors, combining attractive risk-adjusted returns and enhanced yield potential with low correlation to traditional fixed income sectors.
We target predominantly AAA to AA-rated securities with robust structural protections, helping to mitigate default risk. Short duration positioning aims to reduce interest rate sensitivity and provide flexibility in changing market conditions.
The portfolio is actively managed by our specialist US-based securitised credit team with deep market experience and strong credit research capabilities. Our approach blends top-down sector allocation with rigorous bottom-up security selection, seeking to capture relative value opportunities across a range of securitised credit assets.
By combining prudent risk management with access to a deep and diverse market, the fund seeks to deliver stable returns, liquidity, and diversification benefits to institutional portfolios.
