It is the intent of management to meet all reporting deadlines on a timely basis. Management was unable to meet OIAA established standards because of resource constraints created by vacant positions and budgetary limitations associated with the impact of COVID-19. A new Finance Manager has been hired to replace the position vacated since March of 2019 and a new Staff Accountant position has been established. The Staff Accountant will be responsible for preparing these forms going forward under the supervision of the Finance Manager. These additional resources will enable OIAA to meet its reporting deadlines on a timely basis.
