Morningstar says it has bought InvestSoft Technology, which offers fixed-income analytics. According to the Chicago-based research firm, InvestSoft helps investment firms analyze fixed-income securities and portfolios. Its BondPro Fixed-Income Calculation Engine can make more than 130 analytic and accounting calculations.

“Our asset management and advisor clients have been asking for more robust fixed-income capabilities, and InvestSoft’s analytics will help us create a more complete view of mutual fund and exchange-traded fund portfolios, providing investors with better transparency into bond funds,” said Frannie Besztery, head of data for Morningstar, in a press release recently.

Terms of the deal were not disclosed. However, Morningstar says it will “gradually integrate” the firm’s capabilities into its data processing systems and product functionality. The firm also plans to rebrand InvestSoft with the Morningstar name.

“InvestSoft understands the real-time needs of investment firms, and we pride ourselves on the speed and accuracy of our calculations and the seamlessness of our data processing,” said InvestSoft CEO Todd Roitfarb, in a statement. “Now that we are part of Morningstar, we can reach and better serve more investors who need high-quality fixed-income analytics.”

The fixed-income tech group is based in Framingham, Massachusetts. Al Roitfarb founded the original firm in 1992 as Investment Technology, which was acquired by State Street in 2001. Several years later, some members of the firm acquired key software from State Street. After upgrading and redesigning the software Al Roitfarb and his son Todd formed InvestSoft in 2011. Al is now head of architecture for fixed income, while Todd Roitfarb is head of fixed-income products for Morningstar.
