Dec. 4 (Bloomberg) — RadioShack Corp., the struggling electronics retailer, will stop matching employees' retirement- fund contributions and close stores to help cut costs.

RadioShack will discontinue matching for 401(k) and 1165(e) plans on Feb. 1, according to an internal memo from Chief Executive Officer Joe Magnacca that was obtained by Bloomberg. The company plans to close as many as 1,100 stores in its next fiscal year, contingent upon consent from lenders, some of which have blocked attempts to shut them. RadioShack is also reviewing health benefits, according to the memo.

"As a result of these ongoing cost reductions, we are making several difficult but necessary decisions that will allow us to further contain costs and expenses," Magnacca said in the memo.
