"Genatron wants to estimate what will happen to its income before interest and taxes if its net sales change from the 2012 level of $1,500,000. Refer to Genatron’s 2012 income statement below, where the income before interest and taxes is $247,000 (EBT of $190,000 plus Interest of $57,000). Assume that the cost of goods sold are variable expenses and that the other operating expenses are fixed.

Calculate the expected amount of income before interest and taxes for both a 10 percent decrease and a 10 percent increase in net sales for next year.

To calculate the expected amount of income before interest and taxes for a 10 percent decrease and a 10 percent increase in net sales, we need to adjust the relevant figures in the income statement.

1. 10% Decrease in Net Sales:
To calculate the new net sales figure, we multiply the current net sales by 0.9 (1 - 10%).
New Net Sales = $1,500,000 * 0.9 = $1,350,000

Using the formula for calculating the income before interest and taxes, which is equal to Gross Profit minus General & Administrative expenses, Marketing expenses, and Depreciation:
Income before interest & taxes = Gross Profit - General & Administrative - Marketing - Depreciation

From the given income statement, the relevant figures are:
Gross Profit = Net Sales - Cost of Goods Sold = $1,500,000 - $900,000 = $600,000
General & Administrative = $150,000
Marketing = $15,000
Depreciation = $3,000

Plugging in these values, we can calculate the expected income before interest and taxes:
Income before interest & taxes = $600,000 - $150,000 - $15,000 - $3,000 = $432,000

2. 10% Increase in Net Sales:
To calculate the new net sales figure, we multiply the current net sales by 1.1 (1 + 10%).
New Net Sales = $1,500,000 * 1.1 = $1,650,000

Using the same formula as above, we can calculate the expected income before interest and taxes:
Income before interest & taxes = $600,000 - $150,000 - $15,000 - $3,000 = $702,000

Next, let's calculate the percentage change in income before interest and taxes for both scenarios.

Percentage Change = (New Value - Old Value) / Old Value * 100

For the 10% decrease:
Percentage Change = ($432,000 - $247,000) / $247,000 * 100 = 75.91%

For the 10% increase:
Percentage Change = ($702,000 - $247,000) / $247,000 * 100 = 183.41%

Finally, to determine the degree of operating leverage, we use the formula:

Degree of Operating Leverage = Percentage Change in Operating Income / Percentage Change in Sales

For this, we need to calculate the percentage change in operating income.

Percentage Change in Operating Income = (Income before interest & taxes - Old EBT) / Old EBT * 100

Old EBT (income before taxes) is given as $247,000.

For the 10% decrease:
Percentage Change in Operating Income = ($432,000 - $247,000) / $247,000 * 100 = 74.79%

For the 10% increase:
Percentage Change in Operating Income = ($702,000 - $247,000) / $247,000 * 100 = 184.62%

Now we can calculate the degree of operating leverage:

Degree of Operating Leverage (Decrease in sales) = 74.79% / 10% = 7.48
Degree of Operating Leverage (Increase in sales) = 184.62% / 10% = 18.46

To summarize:
- For a 10% decrease in net sales, the expected income before interest and taxes is $432,000, with a 75.91% increase in income before interest and taxes and a degree of operating leverage of 7.48.
- For a 10% increase in net sales, the expected income before interest and taxes is $702,000, with a 183.41% increase in income before interest and taxes and a degree of operating leverage of 18.46.
