Effective January 1, 2008, the Chinese Labor Contract Law was enacted in the PRC. This law mandated that PRC employers remit the applicable social insurance payments to their local government. Social insurance is comprised of various components such as pension, medical insurance, job injury insurance, unemployment insurance, and a housing assistance fund, and is administered in a manner similar to social security in the United States. This amount represents our estimate of the amounts due to the PRC government for social insurance on June 30, 2014 and December 31, 2013.
