On June 19, 2015, the lenders informed Aerocrine that they were accelerating payment of the outstanding principal of $35m as well as prepayment of interest and milestone payments due in the event of acceleration in the amount of approximately $10m. Aerocrine intends to make the full payment of approximately $45m to the lenders within the next several days from cash reserves. Based on forecasted levels of cash and current forecasts for expenses and accounts payable and accounts receivable the company expects to have sufficient cash to operate Aerocrine until such time as additional financing can be obtained.
