Services revenue decreased in the threemonthperiod and increased in the year <strong>2010</strong>.In the fourth quarter of <strong>2010</strong>, we early adopted two new required accounting standards related to revenue recognition: AccountingStandards Update (ASU) 2009-13, Multiple-Deliverable Revenue Arrangements, and ASU 2009-14, Certain Revenue ArrangementsThat Include Software Elements. These new standards generally result in earlier revenue recognition than under previous standards forcertain deliverables in multiple-element arrangements. We adopted these standards effective as of the beginning of <strong>2010</strong>; therefore,the previously reported quarterly results have been revised to reflect the impact of the adoption. Revenue and net earnings in the fourthquarter of <strong>2010</strong> increased by $8.8 million and $0.5 million, respectively. For the year <strong>2010</strong>, revenue and net earnings increased by$9.1 million and $0.5 million, respectively. We adopted these standards in the fourth quarter of <strong>2010</strong> because we were entering intoseveral multi-year agreements. We believe the new rules best reflect the economics of those agreements over time.In the fourth quarter of <strong>2010</strong>, we agreed with a North American customer to add a data product to other <strong>Tellabs</strong> products already soldto that customer through a distributor. This helps the customer better manage inventory and deployment schedules. As a result, werecognized $20.8 million in revenue in the fourth quarter of <strong>2010</strong> that otherwise would have been recognized in the first quarter of2011.On a geographic basis, revenue from customers in North America (United States and Canada) was $240.5 million (or 59% of totalrevenue) in the fourth quarter of <strong>2010</strong>, compared with $255.4 million (or 66% of total revenue) in the year-ago quarter. For the year<strong>2010</strong>, North American revenue grew to $1,142.6 million (or 70% of total revenue), up 13.7% from $1,005.3 million (or 66% of totalrevenue) in 2009. The decrease in revenue for the three-month period was driven primarily by lower revenue for data and digitalcross-connect systems from a major North American carrier. The increase in revenue for the year <strong>2010</strong> was driven primarily by higherrevenue for data and digital cross-connect systems from the same customer.Revenue from customers outside North America grew to $170.0 million (or 41% of total revenue) in the fourth quarter of <strong>2010</strong>, up27.0% from $133.9 million (or 34% of total revenue) in the year-ago quarter. For the year <strong>2010</strong>, revenue from customers outsideNorth America was $499.7 million (or 30% of total revenue), compared with $520.4 million (or 34% of total revenue) in 2009. Theincrease in revenue for the three-month period was driven primarily by higher revenue from data products in the Europe, Middle Eastand Africa region. The decline in revenue for the year <strong>2010</strong> was driven primarily by lower revenue from data products in the AsiaPacific region.

The$16.5 million pretax charge relates to excess purchase commitments for a large tender in India that was subsequently cancelled by thecustomer. Excluding this charge, gross margin for the fourth quarter of <strong>2010</strong> was 42.0%. The increase in products gross margin for theyear <strong>2010</strong> was driven primarily by higher level of revenue from higher-margin digital cross-connect systems and data products.Services gross margin declined in three-month period as a result of the overall lower level of services revenue. For the year <strong>2010</strong>, thedecline in services gross margin was driven by the higher level of lower-margin deployment services.Operating Expenses (in millions) Fourth <strong>Quarter</strong> Percent of Revenue<strong>2010</strong> 2009 Change <strong>2010</strong> 2009Research and development $ 82.9 $ 67.1 $15.8 20.2% 17.2%Sales and marketing 46.8 42.0 4.8 11.4% 10.8%General and administrative 26.7 24.8 1.9 6.5% 6.4%Subtotal 156.4 133.9 22.5 38.1% 34.4%Intangible asset amortization 6.1 6.6 (0.5)Restructuring and other charges - 0.6 (0.6)Total operating expenses $162.5 $141.1 $21.4YearPercent of Revenue<strong>2010</strong> 2009 Change <strong>2010</strong> 2009Research and development $299.7 $268.7 $31.0 18.2% 17.6%Sales and marketing 179.3 165.9 13.4 10.9% 10.9%General and administrative 100.4 101.4 (1.0) 6.1% 6.6%Subtotal 579.4 536.0 43.4 35.3% 35.1%Intangible asset amortization 27.0 24.6 2.4Restructuring and other charges 9.5 11.7 (2.2)Total operating expenses $615.9 $572.3 $43.6Operating expenses increased during the fourth quarter and the year <strong>2010</strong>, compared with the year-ago periods, due primarily tohigher research and development for growth products for the mobile internet as well higher sales and marketing costs associated withexpansion into growth markets outside North America.
