Not sure. If you take the asset as a whole, then it naturally depreciates. Pieces of that whole could have periodic surges in value, but would they actually slow that depreciation or increase the overall value of the entire asset? I'm betting it would just slow depreciation overall, but that can be gamed as well. I'm still thinking they would counter any gains made on licensing pieces of that whole with the tax shelter provided by the overall depreciation. Those strategies can be intricate. I'm thinking there's immense value in licensing a certain percentage of that catalog, but not for reissues so much as advertising. Since there's a complete void of soul in a SPAC, they're not going to care which widget is going to win a gain, just that there's a gain to be had.
What little I know about the Concord deal seems to be that they just use that asset deprecation as a tax shelter and that's all they want to do. This may be different, and likely will be, due to the aggressive profit motives of PE and SPAC entities.
