Acquisitions

Twelve acquisitions of complementary companies, products or technologies to supplement our internal growth were completed to date. The acquisitions served to expand our customer base, accelerate technological developments and build scale. Future acquisitions are not expected to be central to our growth strategy as the three acquisition goals of customers, technology and scale have been met. Our future growth will be focused on organic growth in emerging growth markets. Our historical acquisitions include the following:
