Cost of sales as a percentage of sales varied in each quarter depending on the mix of sales between customers. Operating expenses increased in each quarter primarily as a result of the increase in the number of employees in research and development, sales and marketing, as well as finance and administrative functions. The increased headcount resulted from our need to support our sales growth. A large portion of our expenses, including rent and salaries, are set based upon expected future sales. Accordingly, if sales are below expectations, operating results may be adversely affected. |
