When caught off guard by unforeseen events like this, some companies will look to financing from lenders to keep their heads above water before FTE cuts, where others will make difficult cuts before taking on debt as a last resort.
And most, numerically, radio stations can't get loans. Broadcast lenders will do deals with groups that have distributed exposure over multiple markets with multiple stations in each. It is really hard for smaller groups and local stations to get a lender to cover any more than the real estate of transmitter sites and other real property. Banks don't like the lack of tangible assets a radio station has.
So in such situations, the only possibility is cutting expenses to the maximum.
