Supermarket operator Great Atlantic & Pacific Tea Co. is seeking to sell all of its remaining stores, including locations on Long Island, as part of its Chapter 11 bankruptcy proceeding.

Previously the company had said it would sell some but not all of its stores, and it has received bids for 118. Now it says in U.S. Bankruptcy Court for the Southern District of New York, in Manhattan, that it will also seek bids for the remaining 153 stores, including 35 on Long Island.

The deadline to submit a bid for one or more stores is Sept. 11. Auctions for stores have been scheduled for Sept. 24 and Sept. 25. The stores to be sold operate under the banners A&P, Waldbaum's, Pathmark, SuperFresh, Food Basics, The Food Emporium, Best Cellars, and A&P Liquors.

A representative for the company declined to comment.

Acme Markets Inc., Stop & Shop Supermarket Co. and Key Food Stores Co-operative Inc. have already submitted separate bids for 118 stores for about $600 million. Each bid remains subject to higher offers.

A&P, based in Montvale, New Jersey, filed for Chapter 11 bankruptcy last month. The filing allows the company to continue operating while being protected from creditors.

Stop & Shop said it agreed to acquire 25 A&P stores in New York and New Jersey for $146 million. The Long Island stores on the list include Waldbaum's locations in East Hampton, Southampton, Baldwin, Massapequa, Long Beach and Huntington, and Pathmarks in Greenvale, Seaford and Franklin Square.

Key Food initially agreed to take over 19 stores but reduced its offers to 17 stores. Key Food plans to take over two Waldbaum's locations on Long Island, in Albertson and Glen Head.

Acme Markets agreed to purchase 76 stores in New York -- none on Long Island -- New Jersey, Connecticut, Pennsylvania and Delaware.

The purchase agreements are not final since they are subject to bankruptcy court approval, pending the expected auction.

A&P also announced it will close 25 stores, including five on Long Island: Pathmark stores in Baldwin and Centereach, and Waldbaum's in Carle Place, Oceanside and Riverhead. The stores will close in the next few months but will remain fully stocked until then, the company said.

A&P, founded in 1859, operates nearly 300 stores, including 33 Waldbaum's and 19 Pathmarks on Long Island.

In its Manhattan bankruptcy filing, the company reported total assets of about $1.6 billion and total liabilities of about $2.3 billion, as of Feb. 28.

A&P previously filed for bankruptcy in 2010.

The bankruptcy court will conduct a sale hearing on Sept. 21 at 10 a.m. if a bid is the only qualified bid. If there is more than one qualified bid, the hearing to consider the proposals will be on Oct. 7 at 10 a.m.
