February Transactions
02/01	Included in WWCs February 1 Accounts Receivable balance is a $1,300 account due from Kit Kat, a WWC customer. Kit Kat is having cash flow problems and cannot pay its balance at this time. WWC arranges with Kit Kat to convert the $1,300 balance to a note, and Kit Kat signs a 6-month note, at 12% annual interest. The principal and all interest will be due and payable to WWC on August 1, 2012.
