Start-up costs of the Humber's new Freeport company are expected to be funded by a £3 million loan from the region's four local councils.
Details of the financial support package are currently the subject of on-going talks between the authorities and the new company, which is due to submit its full business case to the government at the end of the month.
However, senior councillors in Hull were told this week it was anticipated the company was unlikely to be in a position to financially support itself for at least three years.
