Presented below are two independent situations:

(a) On January 1, 2015, Excess Inc. purchased undeveloped land that had an assessed value of $261,000 at the time of purchase. A $500,000, zero-interest-bearing note due January 1, 2020, was given in exchange. There was no established exchange price for the land, nor a ready market value for the note. The interest rate charged on a note of this type is 15%. Determine at what amount the land should be recorded at January 1, 2015, and the interest expense to be reported in 2015 related to this transaction.
(b) On January 1, 2015, DonnAll Diamond borrowed $1,000,000 (face value) from Allstar Co., a major customer, through a zero-interest-bearing note due in 3 years. Because the note was zero-interest- bearing, DonnAll agreed to sell diamonds to this customer at lower than market price. A 12% rate of interest is normally charged on this type of loan. Prepare the journal entry to record this transaction and determine the amount of interest expense to report for 2015.
