"Sears should aggressively pursue a divestiture of all or a portion of Kenmore, Sears Home Improvement and Parts Direct," Lampert wrote in the April 20 letter, which simultaneously expressed Lampert's interest in purchasing them. "Pursuing these divestitures now will demonstrate the value of Sears' portfolio of assets, will provide an important source of liquidity to Sears and could avoid any deterioration in the value of such assets." Sears said in a statement Monday that the proposal will be reviewed by a panel of independent board members, without input from Lampert or ESL President Kunal S. Kamlani, who is also a Sears director.
