Kernrechtsfrage
Whether the claimant was entitled to an invalidity pension
Extrahierter Entscheid
No pension entitlement existed because the disability degree remained non-rent-qualifying.
Extrahierte Begründung
The claimant was correctly treated as self-employed/entrepreneurially controlling his companies; the income comparison based on multi-year earnings was permissible and yielded only about 21% invalidity, below the threshold for a pension.
