Common questions
Frequently Asked
3
How does the principal amount differ from interest in a loan agreement?+
The principal amount is the base sum borrowed or owed, while interest represents the additional cost of borrowing calculated on that base. Courts and statutes treat the two separately when determining payments, deficiencies, or tax consequences.
What happens to the principal amount when a contract is discharged for frustration of purpose?+
The remaining duty to pay the principal amount is discharged if a supervening event substantially frustrates the contract's principal purpose without the party's fault and the non-occurrence of that event was a basic assumption. The discharge applies unless the contract language indicates otherwise.
Does the principal amount of a loan affect diversity jurisdiction calculations?+
Yes. The amount in controversy for diversity jurisdiction includes the principal amount sought, and a corporation's citizenship is determined by its state of incorporation and principal place of business when the claim involves recovery of that amount.
