Stanley Forman Reed,
Helvering v. American Dental Company…
“ The release of interest or the complete satisfaction of an indebtedness by partial payment by the voluntary act of the creditor is more akin to a reduction of sale price than to financial betterment through the purchase by a debtor of its bonds in an arms-length transaction. In this view, there is no substance in the Commissioner's differentiation between a solvent or insolvent corporation or the taxation of income to the extent of assets freed from the claims of creditors by a gratuitous cancellation of indebtedness. ”
