Answer:

Cookie & Coffee Creations Inc.

a) Current Portion of Note Payable:

= $4,000

b) Long-term Portion of Note Payable:

= $6,000

Explanation:

Data and Calculations:

Date of Note Payable = November 1, 2017

Period = 3 years

Interest rate = 5%

Terms of payment:

Fixed principal payments = $2,000

Payment dates = May 1 and November 1

Each year's principal repayment = $4,000 ($2,000 x 2)

From November 1, 2017 to October 31, 2018 = $4,000

At October 31, 2018, Payment made = $2,000 on May 1

Remaining Note payable = $10,000 ($12,000 - $2,000)

Current Portion = $4,000 ($2,000 x 2)

Long-term Portion = $6,000

b) The current portion of $4,000 will be payable on November 1, 2018 and May 1, 2019.  The current portion represents the short-term portion of the note payable, which is the portion that will be settled within a 12-months' period.  Since Cookie & Coffee Creations Inc. had already paid $2,000 on May 1, 2018, the long-term portion will only remain $6,000 ($12,000 - $2,000 - $4,000), which is the difference between the total note payable, the portion paid on May 1, 2018, and the current portion of $4,000 that will be payable within one year.
