About MIAIX

MFS Inflation-Adjusted Bond Fund Class I is a mutual fund focused on providing a total return that outpaces inflation over the long term, with particular emphasis on generating current income while also considering opportunities for capital appreciation. The fund primarily invests in U.S. Treasury inflation-protected securities (commonly known as TIPS), as well as inflation-linked bonds from government agencies and select other entities. Through active management of duration and yield curve strategies, the fund aims to enhance performance relative to its benchmark, the Bloomberg U.S. Treasury Inflation Protected Securities Index. This approach makes the fund particularly relevant for investors seeking to preserve purchasing power in inflationary environments. With net assets exceeding $1.4 billion and a history dating back to its inception in 2003, the fund plays a significant role in the fixed income market segment that targets inflation mitigation. It is overseen by an experienced team of portfolio managers and is positioned as a tool for institutional and high-net-worth investors seeking inflation-sensitive fixed income exposure within a diversified portfolio.
