Subsequent Event

In January 2016, the company was the target of criminal fraud by persons impersonating a company executive, which resulted in unauthorized transfers of cash from a Company account in Europe to outside bank accounts in Asia. Investigations and legal actions by the company and law enforcement are ongoing and the results of, and timing to conclude, these investigations is uncertain.  To date, the findings of our investigation indicate that this is an isolated event not associated with a security breach or loss of data.  The company expects to record a one-time charge of approximately of $13,000 in the first quarter of 2016.
