"The Company has one long term project based service contract in which it recognizes revenue when certain milestones have been reached. The customer is not necessarily invoiced at the time a milestone is reached. As at September 30, 2016, billed but uncollected receivable relating to this project was $192,370. This amount was collected in October 2016. There was $293,565 relating to unbilled milestones that were attained."
