Hawthorn International Pty Ltd has not complied with the Superannuation Guarantee Scheme for their three employees. Their superannuation guarantee percentage is 9.5%.

Employees have been provided with annual superannuation support equivalent to only 6% of their earnings base.

The employees' earnings base for quarter 2, 2018/19 was the ordinary times earnings of $56,000. The employees' total earnings including overtime for the quarter was $84,000.

Hawthorn Pty Ltd lodged a SGC Quarterly Statement on 20 February 2019.

(i) Calculate the amount of superannuation guarantee Hawthorn would have already contributed to a complying fund.

$56,000 x 6% = $3,360

(ii) Calculate the employees' shortfall percentage and the shortfall dollar amount.

(iii) Calculate the nominal interest component. Assume 365 days in the year.

(iv) Calculate the administration component.

$20 x 3 = $60

I am having a bit of trouble calculating ii & iii can you please explain the workings for these two calculations?
