Thank you, Dave. Please turn to Slide 9 of the presentation. I'd like to provide you with some of our high-level near-term end market views as background for my comments on strategic priorities and full year 2012 guidance. For North America On-Highway, we expect improved North America economic conditions will support a continued recovery in Allison's core addressable on-highway market. Exceptions to the broader market recovery continue to be school bus, due to municipal spending constraints, and motor homes, given the correlation of consumer net worth and home equity. We expect a slower yet strong year-over-year growth rate in the balance of 2012.
For North America Hybrid-Propulsion Systems for Transit Bus, due to the municipal subsidy and spending constraints, U.S. Environmental Protection Agency 2010 engine emissions improvements and redundancy by alternative -- excuse me, by alternate technologies, we expect a measured decline in net sales of North America hybrid-propulsion systems for transit buses for the full year 2012 below the 2011 level.
For North America Off-Highway, majority of demand is from natural gas fracturing applications. We believe the strong first quarter performance will not persist given recent customer forecast adjustments related to current natural gas pricing. This is an area of our business we are watching very closely.
Although our first quarter wheeled military products net sales were above the 2011 level, we expect a measured decline in net sales for the balance of 2012 below the 2011 level due to reductions in U.S. defense spending. We also expect these spending reductions to result in lower year-over-year net sales of tracked military products.
Outside North America On-Highway, we expect the improved global economic conditions will support a continued recovery in Allison's core on-highway regional end markets. Our commercial initiatives, including end-user-focused marketing activities, OEM long-term supply agreements and vehicle release programs are also expected to drive net sales growth. Despite favorable economic conditions in most regions, we expect continued headwinds in South America given demand volatility in regional markets and delayed resolution of governmental procurement and acquisition difficulties in India. Net sales in South America and India were approximately 1.5% of our total 2011 net sales.
Outside North America Off-Highway, we expect global economic growth will continue to support increased demand for the mining and energy sectors.
Service parts, support, equipment and other. Our service parts, support, equipment and other end market is expected to largely follow global economic conditions and changes in transmission unit volume.
Please turn to Slide 10 of the presentation. For our strategic priorities, they continue as follows: Expanding global market leadership, capitalizing on the continued recovery in on-highway end markets to expand our market presence and OEM relationships. During the first quarter, Allison participated in several new, vocationally focused, outside North America regional trade shows and continued to work towards expanding our vehicle releases in key emerging growth markets by leveraging our technology leadership, value proposition and extensive product portfolio. Allison is on schedule to complete the second phase of our India production facility in the third quarter of 2012.
For emerging markets penetration, we're exploiting our vocational pricing ladder strategy to secure vehicle releases with a defined path to higher value models, utilizing Allison's existing bus presence as an entry point for incremental market penetration and focusing on vocational applications for end users that are well funded and fully value Allison's brand attributes. We're continuing our focus on new technologies and product development. Product development programs such as the TC10 Class 8 Metro transmission and the H3000 hybrid commercial vehicle transmission are intended to expand our core addressable markets. We're also pursuing advanced fuel economy and efficiency in mechanical and hybrid technologies.
Delivering strong financial results. We're pleased with our first quarter performance, which highlighted the benefits of operating leverage, a significant U.S. income tax yield and further deleveraging. With a continued focus on margin enhancement opportunities, our net leverage goal is sub-3.5 within 12 months.
Please turn to Slide 11 in the presentation for full year 2012 guidance. Allison expects 2012 net sales growth in the range of 5% to 7%. Our net sales guidance assumes year-over-year growth in global on-highway and outside North America off-highway end markets, partially offset by year-over-year reduction in the North America off-highway, tracked military and North America hybrid-propulsion systems for transit bus end markets. Allison expects an adjusted EBITDA margin in the range of 33.5% to 34.5%. Capital expenditures are expected to be in the range of $110 million to $130 million, subject to timely completion of development and sourcing milestones for new facilities and product programs. We also expect cash income taxes to be in the range of $10 million to $15 million due to our U.S. income tax yield and net operating loss utilization.
In closing the prepared comments portion of the conference call, I want to acknowledge and express my gratitude to our employees and shareholders for their support in completing a successful IPO. While we look forward to the challenges of being a public company, Allison's strategy and performance-driven culture will not change. We continue to aggressively pursue the expansion of our business in a wide range of applications around the world by leveraging our application engineering and vehicle system integration knowledge and providing a wide range of product variants in a cost-effective manner in order to provide vehicle buyers with products that provide them with a superior value proposition versus their alternatives. I am also confident that by remaining focused and determined in executing our plans, we will continue to be a leader in our industry for years to come. Thank you for your time this afternoon.
Operator, please open the call for questions.
