whose results are included in Industrial, added 5.1% of growth in 2005. In addition to CUNO, growth was led by industrial adhesives and tapes, as well as the abrasives businesses. 3M continues to selectively raise selling prices to offset commodity raw material price pressures. Industrial continues to demonstrate strong operational discipline, as operating income grew 20.5% in 2005.

 

In 2004, Industrial local-currency sales growth of 8.2% for the year was broad-based across major geographic areas and Industrial businesses. Acquisitions increased sales by 1.4%, driven by the February 2004 acquisition of HighJump Software, Inc., a provider of supply chain execution software. Strong local-currency sales growth helped leverage operating income growth. Operating income increased 43.7% to $610 million in 2004.

 

Display and Graphics Business (16.8% of consolidated sales):

  

The Display and Graphics segment serves markets that include electronic display, touch screen, traffic safety and commercial graphics. This segment includes optical film and lens solutions for electronic displays; touch screens and touch monitors; reflective sheeting for transportation safety; and commercial graphics systems. The optical film business provides films that serve numerous market segments of the display lighting industry. 3M provides distinct products for five market segments, including products for: 1) LCD computer monitors 2) LCD televisions 3) handheld devices such as cellular phones 4) notebook PCs and 5) automotive displays. The optical business includes a number of different products that are protected by various patents and groups of patents. The remaining lifetimes of such patents, as well as patents protecting future products, range from less than a few years to greater than 15 years. These patents provide varying measures of exclusivity to 3M for a number of such products. 3M’s proprietary manufacturing technology and know-how also provide a competitive advantage to 3M independent of such patents.

 

In 2005, Display and Graphics local-currency sales grew 4.0%, impacted by many factors. The first half of 2005 was tempered by tough year-on-year optical film comparisons, while 3M’s traffic safety systems business awaited a new highway funding bill in the U.S. and the sluggish economies in Western Europe and Japan held back growth in the commercial graphics business. Growth rebounded in the second half of 2005 as a new U.S. highway funding bill was passed in July, the economies in Western Europe and Japan started to experience some moderate growth and, as expected, 3M saw acceleration in demand for consumer electronics, especially flat-panel LCD televisions and a more normal LCD component inventory situation. This growth in the second half of 2005 drove record sales of 3M’s proprietary optical films and components despite growing pricing pressure. Display and Graphics sales growth was negatively impacted by approximately 4% in 2005 due to the continued decline in lens systems for the CRT rear projection television market along with the phase out of the commercial videotape business announced in the fourth quarter of 2004.
