So much for the Employee Stock Ownership Plan that was at the center of Sam Zell's disastrous purchase of Tribune Co., parent of the LAT. Romenesko has a memo that outlines changes in the company's retirement plan - most of it involving a redesigned 401(k) that will offer a company match and what the memo calls "a discretionary profit-sharing contribution tied to our financial performance." Apparently, none of this is impacted by the Chapter 11 filing. Meanwhile, the shares of Tribune stock held by the ESOP are worthless.
