Restricted Cash
In connection with a proposed sale of our Guangzhou factory in the PRC (Note 13), a prospective buyer made a cash deposit of RMB 32 million ($5.1 million based on April 2018 exchange rates) into an escrow account on September 29, 2016. Under the terms of the escrow account, these funds were not to be paid to us until the close of the sale. Accordingly, this deposit was presented as restricted cash within our consolidated balance sheet. In April 2018, the sale transaction with this buyer was terminated and this deposit was returned to the buyer.
