Are you suggesting the company is not performing annual asset valuation impairment tests properly?
No company has "caught up" to the rapid decline in station values. I can't think of one publicly traded one that has a true realistic asset valuation on its balance sheet.
The problem is that there are very few exemplary transactions that can be used to value a station. Since most station sales have been distress situations, the valuation of stations that are profitable is subjective.
Example: EMF bought a very marginal rock FM in LA that had to be sold due to a merger. It was under-performing in revenue, and (while well programmed by a good PD) was limited by the ethnic transformation of Los Angeles and the severe decline in rock listening overall.
So it sold for a "surprisingly low" price but there were all the extenuating circumstances that made the sale a poor example for the valuation of better performing stations in the market, starting with the time restraints of a forced sale.
So how does an independent auditor verify the asset value of a station? The owners will recognize some attrition in the value of all stations, but they will argue the same points I am making: the worth of a profitable station that is part of a cluster that is part of a group owner is different than a distress sale.
And, without "example transactions" of similar stations and groups, the auditor really can't make a drastic impairment charge.
If fixed or intangible assets are purposely being carried at a net book value that exceeds fair market, then investors are being defrauded.
And that is my point: there is no way to justify an extreme devaluation.
First, there is the pandemic. So valuation can not be done based on revenue since 2020 because there is a reasonable assumption that things will "return to normal". Second, all ad-supported media is "off" due to being on the cusp of a recession, and that is not a valid devaluation anchor point because, historically, recessions are temporary and economies recover. Third, there have been no sales of stations like KIIS or WHTZ or WTOP to use as examples of ratios and values for highly successful properties.
Of course, orderly liquidation value - if that is the "sale price" premise to which you are referring - is a different ball game and does not drive GAAP reporting decisions (unless a purchase and sale agreement or similar instrument has been entered, in which case the affected assets and liabilities get reclassified to held-for-sale on the balance sheet).
And that is the core to this: a station group is not going to be liquidated station by station, transmitter site by transmitter site and so on. The references we have for valuation of functioning groups are, right now, ancient examples of smaller groups selling to bigger ones during consolidation and, roughly, the decade afterwards as groups realigned and smaller ones decided to get out of radio.
