Restricted Cash In connection with the court order issued on September 4, 2015, we placed $4.6 million of cash into a collateralized surety bond. This bond had certain restrictions for liquidation and was therefore classified as restricted cash. On February 10, 2017, the $4.6 million surety bond was returned to us upon final settlement of the related litigation matter. Refer to Note 13 for further information about this litigation. In connection with the pending sale of our Guangzhou factory in the PRC (Note 13), the buyer made a cash deposit of RMB 32 million ($4.9 million based on December 31, 2017 exchange rates) into an escrow account on September 29, 2016. Under the terms of the escrow account, these funds will not be paid to us until the close of the sale. Accordingly, this deposit is presented as restricted cash within our consolidated balance sheet.

- Definition The entire disclosure for cash and cash equivalent footnotes, which may include the types of deposits and money market instruments, applicable carrying amounts, restricted amounts and compensating balance arrangements. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 305 -URI http://asc.fasb.org/topic&trid=2122426 + Details
