In 1994, we invested in our first tiny-tech company, Nanophase Technologies Corporation, a spinoff from Argonne National Laboratory, which completed an initial public offering in 1997. We sold our interest in Nanophase in 2001 and invested part of the proceeds of the sale in August, 2001, in privately held Nantero, Inc., a Harvard University spinoff developing advanced semiconductors using nanotechnology. Including Nantero, our last seven private equity investments have been in tiny-technology enabled companies.
