EBNet did not have the cash flow to pay the independent contractors working on the project so Bruce and Sarah King lent EBNet $10000 to cover those costs. When EBNet donors provided their annual contributions EBNet was able to repay the Kings the $10000 so that amount appears as a project expense related to the BuildWell Media project.
