Ok, I will accept $21M plus the value added by the build out as a reasonable asset value.
The liabilities against this are:
Mortgage: $11.1M
Convert : $8.2M (This has a secondary lien)
Env Mess: $6.2M
Total: $25.5M
The build out market value is tough to estimate. I seriously question what the current market is given Brexit. IMO it still creates a net positive real asset value, but not the large number some think.
No immediate danger of foreclosure. But it is not some large resource to be tapped for funds. That was already used.
NOTE: Before somebody pulls out the $46M carry value on the books, that does not reflect actual value. It is the costs that went into it, and then depreciated. For example, it includes $1.5M of professional fees that they paid to buy it. It also includes the $6.2M toxic dump issue.
