NEW YORK (AP) — While several more global clothing chains on Tuesday were announcing that they agreed to a historic pact to improve factory conditions in Bangladesh, U.S. retailers were scrambling to come up with their own safety plans.

A total of more than a dozen brands this week announced plans to sign a five-year, legally binding contract that requires that they help pay for fire safety and building improvements in Bangladesh. Notably missing from the pact are U.S. firms, except for PVH, the New York-based parent company of Calvin Klein and Tommy Hilfiger.
