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 tables below present the recorded amount of financial assets measured at fair value (in thousands) on a recurring basis as of December 31, 2012 and 2011. The Company did not have any material financial liabilities that were required to be measured at fair value on a recurring basis at December 31, 2012 and 2011.
