Note 11. Cash Deposits and Marketable Securities

Cash deposits are maintained to provide credit enhancement for certain agreements and are reported as part of cash and cash equivalents. For most of these deposits, the cash may be withdrawn if comparable security is provided in the form of letters of credit. Accordingly, these deposits are not considered to be restricted.

A portion of the non-U.S. cash and cash equivalents is utilized for working capital and other operating purposes. Several countries have local regulatory requirements that significantly restrict the ability of our operations to repatriate this cash. Beyond these restrictions, there are practical limitations on repatriation of cash from certain countries because of the resulting tax withholdings.
