FOR IMMEDIATE RELEASE

Morningstar, Inc. Completes Acquisition of tRx Investment Portfolio Rebalancing Platform

CHICAGO, Nov. 2, 2015—Morningstar, Inc. (NASDAQ: MORN), a leading provider of independent investment research, has completed its previously announced acquisition of Total Rebalance Expert (tRx), an automated, tax-efficient investment portfolio rebalancing platform for financial advisors, from FNA, LLC.

tRx streamlines the rebalancing process for advisors and automates the complexities involved in rebalancing and managing portfolios. Advisors can use the software to more easily minimize taxes, harvest losses, and rebalance at the account or household level. They can also use the tool to show clients, in dollars and cents, how much they saved them in taxes. Today, more than 500 financial advisors from 175 firms rely on tRx to rebalance more than $20 billion in client assets. This acquisition adds a key capability—tax-aware rebalancing—to Morningstar’s suite of offerings for independent advisors.
