In January 2012,we agreed with the Administrative Commission of Tianjin Economy and Technology Development Zone to establish a second manufacturing facility in Tianjin, China. The arrangement provides us with land use rights for approximately 32 acres of industrial land located in Yixian Scientific and Industrial Park to construct a compound semiconductor substrate manufacturing facility that would be completed in phases by 2017. We have committed to invest $12.5 million in the first phase of the construction of the facility and have an understanding with our BoYu joint venture that it will commit the RMB 32.0 million, or approximately $5.0 million, that is anticipated to be required for the portion of the project devoted to crystal support, in exchange for land use rights, enterprise and individual income tax rebates, employee hiring and development subsidies, and other benefits.

In January 2012, we increased the credit facility line of credit maintained by us with a bank from $3.0 million to $10.0 million at an annual interest rate of approximately 1.65% above the current 30-day LIBOR (London Interbank Offered Rate).  The annual interest rate is currently approximately 2.0%.
