January Transactions

1. Included in OTPs January 1 Accounts Receivable balance is a $2,400 balance due from Jeff Letrotski. Jeff is having cash flow problems and cannot pay the $2,400 balance at this time. On 01/01, OTP arranges with Jeff to convert the $2,400 balance to a six-month note, at 10% annual interest. Jeff signs the promissory note, which indicates the principal and all interest will be due and payable to OTP on July 1 of this year.
