“The fourth quarter concluded a very successful year for 3M,” said Inge G. Thulin, 3M chairman, president and chief executive officer. “We generated broad-based, profitable sales growth across the portfolio and per-share earnings rose nearly 15 percent in the quarter. Free cash flow conversion was 131 percent, which enabled us to continue investing in our businesses while also returning a record amount of cash to shareholders.”

Thulin continued, “3M employees around the world are bringing our vision and strategy to life and improving 3M’s relevance in the eyes of our customers. Three key levers — namely portfolio management, investing in innovation and business transformation — combined with more aggressive capital deployment, will drive enhanced value creation going forward.”

3M affirmed its 2014 full-year performance expectations. The company expects 2014 earnings to be in the range of $7.30 to $7.55 per share with organic local-currency sales growth of 3 to 6 percent. 3M also expects free cash flow conversion to be in the range of 90 to 100 percent.

(a)3M has historically declared and paid dividends in the same quarter. In December 2013, 3M’s Board of Directors declared a first-quarter 2014 dividend of $0.855 per share (payable in March 2014). This reduced 3M’s stockholders equity and increased other current liabilities as of December 31, 2013, by approximately $0.6 billion.

(b)The changes in 3M’s defined benefit pension and postretirement plans’ funded status, which is required to be measured as of each year-end, significantly impacted several balance sheet amounts. In the fourth quarter of 2013, these required annual measurements increased stockholders’ equity by $0.9 billion, decreased pension and postretirement benefits’ long-term liabilities by $0.8 billion, increased prepaid pension benefits’ assets by $0.5 billion, and decreased deferred taxes within other assets by $0.4 billion. Other pension and postretirement changes during the year, such as contributions and amortization, also impacted these balance sheet amounts.

(c)Free cash flow and free cash flow conversion are not defined under U.S. GAAP. Therefore, they 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 defines free cash flow conversion as free cash flow divided by net income attributable to 3M. The Company believes free cash flow and free cash flow conversion are useful measures of performance and uses these measures as an indication of the strength of the company and its ability to generate cash.

Return on Invested Capital for the twelve-months ended Dec. 31 (e)	20.0	%	19.8	%

(d)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.

(e)The Company uses non-GAAP measures to focus on shareholder value creation. 3M uses Return on Invested Capital (ROIC), defined as annualized after-tax operating income (including interest income) divided by average operating capital. Operating capital is defined as net assets (total assets less total liabilities) excluding debt. This measure is not recognized under U.S. GAAP and may not be comparable to similarly titled measures used by other companies.
