Research and Development Grant
Research and Development Grant	9.  Research and Development Grant The Company received Research & Development (“R&D”) Tax Incentive refunds, net of costs to prepare and file, paid under the Australian Government’s R&D Tax Incentive Program, a program designed to encourage industry to engage in R&D activities that benefit Australia.  These refunds are related to costs we incurred during the 2012 through 2015 fiscal years for qualifying R&D programs. The R&D Tax Incentive Program is a self-assessment process, and as such, the Australian Government has the right to audit the qualifying programs and expenditures for a period of four years. As of December 31, 2017, we have not received any notice regarding a formal review from the Australian Government.
