FAIR VALUE [Abstract]  
Fair value, assets measured on recurring basis
The primary objective of the Company's investment activities is to preserve principal while maximizing yields without significantly increasing risk. The investment instruments held by the Company are money market funds and interest bearing deposits for which quoted market prices are readily available. The Company considers these highly liquid investments to be cash equivalents. These investments are classified within Level 1 of the fair value hierarchy because they are valued based on quoted market prices in active markets. The Company does not have any material financial liabilities that were required to be measured at fair value on a recurring basis at March 31, 2013. The table below presents the recorded amount of financial assets measured at fair value (in thousands) on a recurring basis as of March 31, 2013.
