DALLAS — Bankrupt grocery distributor Fleming Cos. has increased the pace of selling assets, announcing plans to sell its core business and 17 discount grocery stores.

Fleming is negotiating to sell its sole remaining business, which supplies convenience stores, a spokesman said Monday.

Fleming filed for bankruptcy April 1, shortly after severing ties with its largest customer, Kmart Corp. Officials say the company has continued to lose customers since the bankruptcy filing in Delaware.

On Friday, Fleming said it had agreed to sell its wholesale grocery distribution business to privately held C&S Wholesale Grocers Inc. of Brattleboro, Vt.

Financial terms were not disclosed. The deal requires approval of the bankruptcy court.

Fleming said in May it would close its grocery wholesale division in Salt Lake City, putting 125 people out of work, as it shut down several poorly preforming wholesale divisions. Those closures affected about 800 people. The division's Salt Lake activities, operating at a 500,000-square-foot facility at 2455 W. 1500 South, served mostly independent supermarkets within about a 200-mile radius.

The company has a convenience distribution center at 3130 S. 1030 West.

Fleming last week said it had received bankruptcy court permission to sell 17 closed discount grocery stores in Texas and Louisiana for undisclosed terms to Grocery Outlet Inc. of Berkeley, Calif.

The buyer said it planned to reopen the Yes!LESS stores under its own Grocery Outlet Bargains Only banner by late summer. Grocery Outlet, with 118 stores, said it marked the biggest one-time expansion in its 30-year history.

A Fleming spokesman, Shane Boyd, said the sale to Grocery Outlet "substantially" completed the sale of Fleming's retail operations, which once numbered more than 100 stores.

When Fleming completes the sale of its core grocery-distribution business to C&S, it will be left with only one line, the convenience-store supply business it gained with the $430 million acquisition last year of San Francisco-based Core-Mark International Inc. and a smaller distributor in Georgia.

Boyd said Fleming was continuing to talk with potential buyers for the Core-Mark business. Fleming said the unit has continued to generate positive cash flow since the bankruptcy filing.

In June, Fleming announced it would close grocery wholesale divisions in Alabama, Louisiana and Wisconsin by the end of July.

Boyd acknowledged that the company has continued to lose customers since its bankruptcy filing, as stores have made other arrangements for receiving food and supplies, but said he didn't know the number. Some analysts say more than one-third of the company's customers have switched to other shippers.

On the day it filed for bankruptcy protection, Fleming urged its customers to line up secondary shippers. Fleming is based in the Dallas suburb of Lewisville.
