Thompson Plumb Funds: Re-branding fund family name

MADISON, Wis., July 25, 2012 (GLOBE NEWSWIRE) — Thompson Plumb Funds, Inc. is re-branding its name to Thompson IM Funds, Inc. effective September 6, 2012. In conjunction with this re-branding, the name of each of the Thompson Plumb Funds will be changing on that same date as follows: Thompson LargeCap Fund (THPGX), Thompson MidCap Fund (THPMX) and Thompson Bond Fund (THOPX).

“We are re-branding the names of the Fund Company and of each series of Funds to more closely align them with that of Thompson Investment Management, Inc., the Funds’ investment advisor,” stated Jason Stephens, Portfolio Manager and Vice President of the Funds. “This slight adjustment more accurately reflects the close relationship between these entities, and is intended to dispel any minor confusion that may exist among our constituents.”

The change to the Thompson LargeCap Fund name is intended to more accurately reflect that Fund’s investment objective. Although each Fund will be known by a new name, these name changes will not affect any Fund’s investment objective or process, nor will they affect any Fund’s ticker symbol or CUSIP number.

There has been no change to the management team or operational structure of the Fund Company or the Investment Advisor. John W. Thompson, Jason L. Stephens and James T. Evans will continue to be the Portfolio Managers for all three Funds.

“We have explored making a change for several years, but had difficulty identifying something that accomplished what we wanted and at the same time was likely to survive the trademark process,” said John W. Thompson, President and Chief Executive Officer of the Funds. “We are pleased with the final solution, and hope that our shareholders will be as well.”
