The Company has U.S. federal NOL carryforwards available at March 31, 2016 of approximately $25,500,000 (2015 - $24,000,000) that will begin to expire in 2021. The Company has state net operating loss carryforwards of $9,930,000 (2015 - $11,200,000) that began to expire in 2015.  The difference between federal and state net operating loss carryforwards is due to certain percentage limitations of California loss carryforwards and to expired California carryforwards. Certain foreign taxes paid create a foreign tax credit carryover that will be available to offset federal tax expense in future years, subject to certain limitations.  The foreign tax credit carryover expires beginning in 2021.
