Males are easily distinguished from females based on colour differences, with a distinct black patch at the abdomen, less noticeable in recently emerged flies (see fig.), and the sexcombs (a row of dark bristles on the tarsus of the first leg).
total asset turnover. A financial ratio that indicates the effectiveness with which a firm's management uses its assets to generate sales. A relatively high ratio tends to reflect intensive use of assets. Total asset turnover is calculated by dividing the firm's annual sales by its total assets.
To calculate the total asset turnover ratio, you take net sales/total assets. The net sales are the numerator, while the total sales are the denominator. The ratio tells us how efficiently we are using our assets to generate sales. Sales are also called revenue and can be found on the income statement.
