Sonnax is proud to be 100% Employee-Owned!
In 2010, Sonnax announced the formation of an Employee Stock Ownership Plan (ESOP). The ESOP is the ultimate way to reward our employees for their hard work and contributions to the company.
An ESOP is an employee benefit plan that invests primarily in stock of the sponsoring company. The company sets up a trust fund which owns shares of the company stock. At Sonnax, the trust owns 100% of the company stock. Shares in the trust are allocated to individual employee accounts. As employees accumulate seniority within the company, they acquire increased vesting in those shares.
The ESOP helps to provide stable careers and local ownership. It enables a motivating atmosphere where employees can feel good about coming to work every day. And the greatest benefit of the ESOP is that it allows employees to participate in the growth and success of the business.
Of course, being 100% employee-owned is just one of the many wonderful reasons that Sonnax was named one of the best places to work in Vermont. Check out our Career Opportunities page for current openings.
True collaboration toward a common goal is not something you see everyday, but that is what the Sonnax TASC Force is all about.
The Sonnax Technical Automotive Specialties Committee (TASC) Force is composed of experienced transmission rebuilders and technicians who value technical innovations and have hands-on understanding of the latest units and industry developments. From around the globe, the best minds in the transmission industry willingly share their know-how, with the understanding that everyone benefits when good ideas and products emerge from centuries of combined transmission wisdom.
When you see the TASC Force logo on a Sonnax product, it means the product has passed stringent testing by Sonnax and by TASC Force member shops.
Independent TASC members work for large shops, small shops, volume transmission and volume valve body rebuilders. Alongside Sonnax engineers and specialists, they are helping to develop repairs which will be used by their companies and by the rest of the transmission aftermarket.
TASC Force members contribute product ideas, test new products, troubleshoot results, and get together on a regular basis to listen, discuss and compare findings. Their efforts help provide answers and repairs for the entire industry. Everybody wins.
