7.	Restricted Cash

The Washington Department of Health requires the Company to provide collateral for the decommissioning of its facility. To satisfy this requirement, the Company has a certificate of deposit (CD) with a balance $181,420. The CD has an original maturity of twelve months but is termed restricted cash and classified as a long-term asset as the Company does not anticipate decommissioning the facility until the end of the current lease. The current lease expires April 30, 2019. Interest earned on the CD is rolled-over at the maturity of the CD and becomes part of the restricted cash balance. The cash will become unrestricted following the decommissioning of the facility and the release of the facility by the Washington Department of Health back to the landlord.
