13. Mike Kornas signed a 12-month, 9% p.a. simple interest promissory note for $9,725 with MacDonald’s Furniture. After 85 days, MacDonald’s Furniture sold the note to the Royal Bank at a rate of 11%, then Royal Bank resold the note to Friendly Finance Company 42 days later at a rate of 6.25%. Find the gain or loss on this note for each company and bank involved, as well as a rate of return realized. (Don’t forget to add 3 grace days to the term of the promissory note)
Note bought by MacDonald's Furniture:
Present Worth of note = $9,725 | Rate of interest = 9% p.a | Term =12 month+3 days grace period = 365+3 = 368 days
Note: As per the question, added 3 days in the term, otherwise, would have used only 365 days as the term.
Using the Simple Interest formula, we can calculate Future worth of the Note.
Future Worth = Present worth * (1 + Rate of interest * Time)
Future Worth = 9,725 * (1 + 9% * 368 / 365)
Future Worth of the note = 9,725 * 1.09074
Future Worth of the note = $10,607.44
MacDonald's Furniture sold the note to Royal Bank:
Days elapsed = 85 days | Rate of interest = 11%
Remaining Term of the note = Original term - Days elapsed = 368 - 85 = 283 days
Now rearranging the Future worth formula used above, we will calculate the Present Worth of Note with new terms.
Present Worth of note after 85 days = Future Worth / (1 + New rate * Remaining days / 365)
Present Worth of note after 85 days = 10,607.44 / (1 + 11% * 283 / 365)
Present Worth of note after 85 days = 10,607.44 / 1.08529
Present Worth of note after 85 days = $ 9,773.85
MacDonald's Furniture Buy Price = $ 9,725
MacDonald's Furniture Sell Price = $ 9,773.85
Gain for MacDonald's Furniture = Sell Price - Buy Price = 9,773.85 - 9,725 = $ 48.85
Rate of Return for MacDonald's Furniture = Gain / Buy Price = 48.85 / 9,725 = 0.5024% or 0.50%
Royal Bank sold the note to Friendly Finance Company:
Days elapsed since Royal Bank bought the note = 42 days
Total Days elapsed in Note's term = Days after MacDonald's Furniture sold + Days after Royal Bank sold
Total Days elapsed in Note's term = 85 + 42 = 127 days
Remaining days in Note's Term = Original term - Total days elapsed = 368 - 127 = 241 days
Rate of Interest = 6.25%
Now we will calculate the Present worth of the note after 127 days elapsed.
Present Worth of note after 127 days = Future Worth / (1 + New rate * Remaining days / 365)
Present Worth of note after 127 days = 10,607.44 / (1 + 6.25% * 241 / 365)
Present Worth of note after 127 days = 10,607.44 / 1.04127
Present Worth of note after 127 days = $10,187.05
Royal Bank's Buy Price = $ 9,773.85
Royal Bank's Sell Price = $10,187.05
Gain for Royal Bank = Sell Price - Buy Price = 10,187.05 - 9,773.85 = 413.20
Rate of return = Gain / Buy Price = 413.20 / 9,773.85
Rate of return for Royal Bank = 4.228% or 4.23%
Since there is no transaction after note was sold to Friendly Finance Company (FFC), therefore, FFC would receive the Future worth of note.
FFC's Buy Price = $10,187.05
FFC's receipt at the end of note's term = $10,607.44
Gain for Friendly Finance Company = Note's maturity receipt - Buy Price = 10,607.44 - 10,187.05
Gain for Friendly Finance Company = $ 420.39
Rate of Return = Gain / Buy Price
Rate of Return for Friendly Finance Company = 420.39 / 10,187.05 = 4.127% or 4.13%
