Tefron, an Israeli maker of seamless and engineered clothing, has signed a memorandum of understanding with lenders to expand its credit line. The deal ensures the continuation of the $28.95 million line of credit and adds $1.8 million, ending a month of financial uncertainty for the company. It also calls for the addition of at least $4 million in equity investment, which shareholders have agreed to make at an upcoming rights offering. The memorandum was signed with Bank Leumi le-Israel, Bank Discount le-Israel and Bank Hapoalim. Tefron is a supplier to Nike, Patagonia and Lululemon Athletica, among others.
