We were able to significantly increase our performance in 2013 in a number of key areas. From a market share perspective, we achieved the number two position in global Broadband DSL aggregation revenue and the number two position in broadband revenue for our target markets of North America and EMEA. 1  We continued to diversify our customer mix and increased our global penetration to 68 countries. An expanded customer base and diversified customer mix will be essential to the long-term, sustainable growth of the company. International markets now account for 29 percent of our total revenue, rising from just five percent in 2010. 

From a product perspective, we reported growth across all three of our core product segments. Internetworking led the way with 15 percent year- over-year growth, followed by Optical at seven percent and Broadband Access at six percent. Our success in Internetworking was fueled by contin- ued demand for our industry-leading IP Business Gateways by service providers and Cable/MSOs, as well as increased demand for our Ethernet switch products through our Value-Added Reseller (VAR) channel. Growth in our Optical products was helped 

As a global market leader, ADTRAN is committed to our investors, customers, and employees. 

## GROW 

by the market adoption of our Optical Networking Edge (ONE) solution and we expect to see growing adoption of this solution in 2014 and beyond. Our broadband success continues to be driven by sales of the hi-X and the Total Access 5000 product families. 

Strengthening our channels to market remains a priority for the company. We successfully grew our VAR program with the addition of over 300 new resellers in 2013, bringing our total to approximately 3,800 partners. We also provided a range of new products and services, for the VAR Channel, includ- ing our first cloud-based managed service offering, that enabled our partners to develop new commercial opportunities, expand addressable markets and win new business for both themselves and ADTRAN. 

In our ongoing focus to return value to our share- holders, we continued to reinvest in the company through a stock buyback program. In May 2013, an additional five million shares were added to this pro- gram. Throughout the year, the company repurchased 5.6 million shares of ADTRAN stock valued at $124.3 million. As of December 31, 2013, there were 3.5 mil- lion shares remaining under this program.
