2003 FORM 10-K ZIMMER HOLDINGS, INC. AND SUBSIDIARIES The Company believes that its relationship with its employees and the unions that represent them is good. sole source availability, cost effectiveness or constraints resulting from regulatory requirements. The Company works closely with its suppliers to assure continuity of supply while maintaining high quality and reliability. Alternative supplier options are generally considered and identified, although the Company does not typically pursue regulatory qualification of alternative sources due to the strength of its existing supplier relationships and the time and expense associated with the regulatory process. Although a change in suppliers could require significant effort or investment by the Company in circumstances where the items supplied are integral to the performance of the Company’s products or incorporate unique technology, the Company does not believe that the loss of any existing supply contract would have a material adverse effect on its financial and operational performance. To date, the Company has not experienced any significant difficulty in locating and obtaining the materials necessary to fulfill its production schedules.
