International Financial Data Services, the transfer agency joint venture between State Street Corporation and DST Systems, has completed the conversion and integration of Henderson Global Investors’ open- and closed-ended fund ranges.

Under the deal Henderson has consolidated and outsourced its investor record-keeping and transfer agency to IFDS on a full-service basis, the firms said in a statement. This includes the servicing of distributors and financial institutions, along with the investor and advisor call centre for its UK range of open- and closed-ended funds.

“The transition to IFDS, in conjunction with our rebranding exercise, completes the integration of New Star for our UK Retail business. The transition has been a great success and involved extensive effort and planning by everyone involved to complete on time,” Alan Hardgrave, chief operating officer at Henderson Group, said in a statement.

IFDS currently provides investor record-keeping and transfer agency services to over 200 firms, representing over 17 million accounts and 5,000 funds. Among the high-profile additions to IFDS’ client roster over the past year is Aviva Investors, which in October of 2009 outsourced to the firm its investor record-keeping and transfer agency functions.
