Exa Corp. (EXA) provides software for simulation driven product design. The stock experienced erosion in its price during the period, which made it the second largest detractor to performance. We view the company as being an open-ended growth opportunity as software based simulation benefits from prototyping in transportation markets. Simulation reduces the need for expensive prototypes, increases automation, and allows for faster turnaround times, which ultimately result in customer savings. Exa signs annual consumption-based licenses with customers, which we believe create predictable revenue streams with low volatility.
