About CSTIX

Calamos Short-Term Bond Fund Class I is an open-end mutual fund focused on generating a high level of current income while emphasizing preservation of principal over a one- to two-year horizon. The strategy maintains a short effective duration and invests primarily in investment‑grade debt, with flexibility to allocate across U.S. Treasuries and agencies, corporate bonds, mortgage‑ and asset‑backed securities, repurchase agreements, and select convertible and preferred securities; it may invest up to a limited portion in below‑investment‑grade bonds. The fund follows a multi‑sector fixed income approach, seeking to outperform short-duration government/credit benchmarks over market cycles through sector rotation, security selection, and active duration management. Positioned within the short-term bond category, it targets medium credit quality with limited interest rate sensitivity, aiming to balance income generation with lower volatility compared with intermediate or long-duration peers. The share class is designed for institutional allocators, featuring a below‑average distribution fee profile and competitive expenses relative to category norms. The fund’s role in portfolios typically includes cash-plus exposure, liquidity management, and diversification of interest rate and credit risk within a conservative fixed income sleeve.
