Using our existing channel in North America and REFUsol's infrastructure in emerging territories including India, Asia, Mediterranean countries and Eastern Europe, we can more quickly gain access to and penetrate areas with the greatest growth prospects. Combined with our relentless focus on costs, we see this acquisition as instrumental to achieving our strategic goals and returning significant value to our shareholders."
