Trust chairman Michael Fowler said a strategic review of the trust's activities and priorities began in 2019 and the dramatic and swift impacts of Covid-19 have heightened the need for change.
The trust says the return of domestic holidaymakers, while "very welcome", will not substitute for the economic loss of international tourists.
Sources of financial support for the trust are "extremely limited" but it would look into investigating funding opportunities over the next month.
Fowler says the board has commissioned an independent, detailed appraisal of the trust's current financial position and future financial forecast.
"Once we have that expert assessment, we can assess the practical options to secure the trust's long-term financial sustainability and strategic direction.
"We also intend making sure our volunteers and members have the same information. We appreciate that there is community interest in the future of the trust.
"Having said that, our priority is and by law must be, to consult first with our paid employees. Only once we have completed that process will we be able to meet with members and volunteers.
"Until we have worked through the review process, nothing is pre-determined and as we have said previously, the future of the Art Deco Festivals and our heritage preservation work is not in question.
He said to make a "prudent" decision, all facts needed to be on the table.
A decision is expected by the end of June.
