A company loan of $$200,000$ to help finance the purchase of a new home in Dundas. The loan will bear interest at $3\mathrm{.}5\%$ per year payable monthly and will be made on May $1,2008,$ the closing date on the purchase of the home. Assume that the prescribed rate of interest for employee loans is $7\%$ in the first quarter of the year, $6\%$ in the second quarter, $4\%$ in the third quarter and $7\%$ in the fourth quarter. Ignore the leap$-$year effects.

The housing loan benefit included in her employment income will be computed as follows according to the CRA$$s administrative practice.

$6\%(1)$ of $$200,000$ x $(61/365)=$ $$2,005$

$4\%(1)$ of $$200,000$ x $(92/365)=$ $$2,016$

$6\%(1)$ of $$200,000$ x $(92/365)=$ $$3,025$

Less: interest paid $(3\mathrm{.}5\%$ of $$200,000$ x $245/365)=$ $$4,699$

Net employment income inclusion $$2,347$

$(1)$ The lesser of the prescribed rate for the quarter and the prescribed rate at the time the loan was made.

Where do the numbers $6\%,4\%,$ and $6\%$ come from if $3\mathrm{.}5\%$ is lower than all of them? Explain clearly and show calculations.
