30 Introduction of V-series steering product.

31 Sauer-Danfoss steering Unit Introduction Introduction: V-series is a lower cost steering unit (20-30% below OSPC); with lower performance expectations, while maintaining high Quality manufacturing processes in production, to maintain consistancy and reliability over the machine life. Goal is to increase market share globally. Initially target markets are India, China, but with high focus on the rest of the world where volume machine production is emerging. Sales focus started Q2 (2012) with larger OEMs. Already working with some of the target customers globally. General release for lower volume customers and Distribution planned for the end
