A party may be named the creditor of the liabilities the company owes it
itself: a card's issuer, a loan's lender, each member for what the
members advanced. For an entry naming it, a credit to one is a promise,
not a payment: a fee on the issuer's own card, equipment bought on the
seller's own note, a distribution credited to what the members are owed.
It counts when it is paid. Property a member contributes subject to a
loan counts at its value net of the loan, in kind.
