(a)              Free cash flow is not defined under U.S. GAAP. Therefore, it should not be considered a substitute for income or cash flow data prepared in accordance with GAAP and may not be comparable to similarly titled measures used by other companies. The company defines free cash flow as net cash provided by operating activities less purchases of property, plant and equipment. It should not be inferred that the entire free cash flow amount is available for discretionary expenditures. The company believes free cash flow is a useful measure of performance and uses this measure as an indication of the strength of the company and its ability to generate cash. 

(b)              The company uses various working capital measures that place emphasis and focus on certain working capital assets and liabilities. 3M’s net working capital index is defined as quarterly net sales multiplied by four, divided by ending net accounts receivable plus inventory less accounts payable. This measure is not recognized under U.S. GAAP and may not be comparable to similarly titled measures used by other companies.
