$5.96 per diluted share in 2011, compared to $4.085 billion, or $5.63 per diluted share, in 2010 (including the first-quarter 2010 special item discussed below).

 

During 2011, 3M was impacted by the first-quarter earthquake and tsunami in Japan and by the fourth-quarter flooding in Thailand. Automobile and electronic manufacturers were most impacted; thus, 3M’s automotive OEM and electronics-related businesses were most affected. 3M estimates that combined direct and indirect business disruption resulting from the 2011 Japan natural disaster, net of the benefit from sales of 3M products used in the reconstruction efforts and initial insurance recoveries, plus the impact of Thailand flooding, reduced 2011 sales growth by an estimated 0.8 percentage points and earnings by approximately 6 cents per diluted share, with most of this impact in the first half of 2011. In the fourth quarter of 2011, the flooding in Thailand reduced sales growth by an estimated $35 million and operating income by $20 million, with this operating income effect offset by $23 million in insurance recoveries related to the earthquake and tsunami in Japan. Japan represented approximately 9 percent of total 3M sales for total year 2011. Related to these natural disasters, no material asset or investment impairments were recorded. In addition, 3M did not have any significant issues related to these natural disasters concerning inventories, customer receivables, lease terminations, environmental exposures, guarantees, indemnifications, debt covenant compliance, or significant tax issues. 3M does have certain insurance coverage which limited its exposure and resulted in some initial recovery in the fourth quarter of 2011 (as discussed above).

 

In 2010, 3M recorded a one-time, non-cash income tax charge of $84 million, or 12 cents per diluted share, resulting from the March 2010 enactment of the Patient Protection and Affordable Care Act, including modifications made in the Health Care and Education Reconciliation Act of 2010. Refer to the special items discussion at the end of this overview section for more detail.
