Arco Ponders New Cost-Cutting Moves: : Atlantic Richfield Co., under the guidance of new Chief Executive Mike R. Bowlin, is looking at ways to reduce expenses in an era of low crude oil prices, analysts said. Arco, which holds its annual meeting Monday, is considering a shake-up that could include layoffs, capital spending cuts and a stock buyback, they said. An Arco spokesman said the company has made no secret of the fact that it is looking at ways to reduce costs, probably including “work force reductions,” but he said it will not make any decisions until summer.
