, 2007 , down from 5.4 at december 31 , 2006 . receivables increased $ 260 million , or 8.4% ( 8.4 % ) , compared with december 31 , 2006 . currency translation increased accounts receivable by $ 159 million year-on-year , as the u.s . dollar weakened in aggregate against a multitude of currencies . inventories increased $ 251 million , or 9.7% ( 9.7 % ) , compared with december 31 , 2006 . currency translation increased inventories by $ 132 million year-on-year . accounts payable increased $ 103 million compared with december 31 , 2006 , with $ 65 million of this year-on-year increase related to currency translation . cash flows from operating , investing and financing activities are provided in the tables that follow . individual amounts in the consolidated statement of cash flows
