Research and Development Grant
Research and Development Grant	10. 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. If such a review were to occur, and as a result of the review and failure of a related appeal a qualified program and related expenditures were disqualified, the respective R&D grant could be recalled with penalties and interest. As of December 31, 2016, the Australian Government has not requested a review.
