KANSAS CITY, Mo. _ Interstate Bakeries Corp., the maker of Wonder bread and Hostess Twinkies, said Tuesday it will exit the bread business in Southern California, cutting about 1,300 jobs. The Kansas City-based company, in Chapter 11 bankruptcy protection since 2004, said it will close four bakeries in Glendale, Pomona, San Diego and Los Angeles. It will also consolidate about 325 distribution routes and close 17 distribution centers and 19 outlet stores. Interstate Bakeries said the moves, which require approval by a bankruptcy court judge and the company’s lenders, should be completed by Oct. 29 and will require $29.2 million in charges and an additional $1.8 million in accrued expenses. “While IBC has made marked progress in several problem markets over the last six months, bread operations in Southern California continue to be unprofitable,” Craig Jung, the company’s chief executive, said in a news release. Jung said the company has struggled in the region with low-cost competitors, changing consumer demand and labor problems. However, the company said it will continue selling Hostess and Dolly Madison branded snack cakes and doughnuts in the area. “We must stop reinforcing failure and press harder where there is success,” he said. The cuts, equal to about 5 percent of the company’s remaining employees, come as Interstate Bakeries continues to seek a path out of almost three years of bankruptcy protection. In that time, the company has slashed its work force by 22 percent and shut down 10 bakeries and numerous distribution centers and thrift stores. It has lost a combined $620 million over the past three fiscal years. Interstate Bakeries has run into an impasse as it seeks concessions from unions that represent 82 percent of its 25,000 employees. Chiefly, Jung wants to move the company from its current distribution method where delivery drivers also sell products to a “path-to-market” system, in which distribution and sales are more separate. The company said path-to-market gives salespeople more time to work with store managers to merchandise the products instead of simply delivering them. It also would allow some customers to order products over the phone or Internet, cutting down on distribution expenses. The International Brotherhood of Teamsters has criticized the plan in a letter to its 10,000 Interstate Bakeries members _ many of whom could be affected by changes in delivery policies _ saying that other companies have tried and later abandoned similar distribution methods and that it has yet to be tried in the baking industry. “We do not share IBC’s view that its business plan will allow the company to emerge from bankruptcy; nor do we agree that IBC’s untested Path-to-Market delivery system is the only way for the company to survive,” Richard Volpe, the Teamster’s international director, said in the Aug. 22 letter. Sandi Sternberg, an Interstate Bakeries spokeswoman, responded that Jung and other members of company management have implemented path-to-market at other companies with success. “IBC’s distribution system has not fundamentally changed in 75 years and has failed to account for both advances in technology and changes in grocery store and consumer preferences,” Sternberg said. “We believe our path-to-market system can give us a huge competitive advantage by meeting the grocery industry’s desire for high-quality, seven-day-week service.” Volpe also said the union has suggested a number of ways to cut other operations, which it said would save the company $295 million over five years. But Jung on Tuesday warned that the company is running out of time. It has until Oct. 5 to propose a reorganization plan or anyone else can make a proposal, including selling the company. “We have weeks, not months or years, to act,” Jung said. “Union agreement to path-to-market and the health and welfare concessions in our business plan are crucial.” Shares of Interstate Bakeries, which trade on the over-the-counter market, were up 10 cents at $1.20 in late morning trading Tuesday.160Want local news?Sign up for the Localist and stay informed Something went wrong.
