78CWhat is the interest charge rate?

#### 78C What is the interest charge rate? (1) For the purposes of sections 78 and 78A, the interest charge rate for a day is the rate worked out by adding 7 percentage points to the base interest rate for that day, and dividing that total by the number of days in the calendar year. (2) The base interest rate for a day depends on which quarter of the year the day is in. For each day in a quarter in column 1 of the table, it is the monthly average yield of 90‑day Bank Accepted Bills published by the Reserve Bank of Australia for the month in column 2 of the table. ```html <table cellspacing="0" cellpadding="0" style="margin-left:5.35pt; border-collapse:collapse"><thead><tr><td colspan="3" style="width:336.6pt; border-top:1.5pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="TableHeading"><span>Base interest rate</span></p></td></tr><tr><td style="width:24.75pt; border-top:0.75pt solid #000000; border-bottom:1.5pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="TableHeading"><span>Item</span></p></td><td style="width:109.8pt; border-top:0.75pt solid #000000; border-bottom:1.5pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="TableHeading"><span>Column 1</span><br><span>For days in this quarter:</span></p></td><td style="width:180.65pt; border-top:0.75pt solid #000000; border-bottom:1.5pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="TableHeading"><span>Column 2</span><br><span>the monthly average yield of 90</span><span>‑</span><span>day Bank Accepted Bills for this month applies:</span></p></td></tr></thead><tbody><tr><td style="width:24.75pt; border-bottom:0.75pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>1</span></p></td><td style="width:109.8pt; border-bottom:0.75pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>1</span><span> </span><span>January to 31</span><span> </span><span>March</span></p></td><td style="width:180.65pt; border-bottom:0.75pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>the preceding November</span></p></td></tr><tr><td style="width:24.75pt; border-top:0.75pt solid #000000; border-bottom:0.75pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>2</span></p></td><td style="width:109.8pt; border-top:0.75pt solid #000000; border-bottom:0.75pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>1</span><span> </span><span>April to 30</span><span> </span><span>June</span></p></td><td style="width:180.65pt; border-top:0.75pt solid #000000; border-bottom:0.75pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>the preceding February</span></p></td></tr><tr><td style="width:24.75pt; border-top:0.75pt solid #000000; border-bottom:0.75pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>3</span></p></td><td style="width:109.8pt; border-top:0.75pt solid #000000; border-bottom:0.75pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>1</span><span> </span><span>July to 30</span><span> </span><span>September</span></p></td><td style="width:180.65pt; border-top:0.75pt solid #000000; border-bottom:0.75pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>the preceding May</span></p></td></tr><tr><td style="width:24.75pt; border-top:0.75pt solid #000000; border-bottom:1.5pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>4</span></p></td><td style="width:109.8pt; border-top:0.75pt solid #000000; border-bottom:1.5pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>1</span><span> </span><span>October to 31</span><span> </span><span>December</span></p></td><td style="width:180.65pt; border-top:0.75pt solid #000000; border-bottom:1.5pt solid #000000; padding-right:5.35pt; padding-left:5.35pt; vertical-align:top"><p class="Tabletext"><span>the preceding August</span></p></td></tr></tbody></table> ``` (3) If the monthly average yield of 90‑day Bank Accepted Bills for a particular month in column 2 of the table in subsection (2) is not published by the Reserve Bank of Australia before the beginning of the relevant quarter, assume that it is the same as the last monthly average yield of 90‑day Bank Accepted Bills published by the Reserve Bank of Australia before that month. (4) The base interest rate must be rounded to the second decimal place (rounding .005 upwards).
