Step-by-step explanation:
1. Net profit margin ratio (%) for 2017 will be:
= Net income/Net sales
= 6220/89500
= 0.0695
= 6.95%
Net profit margin ratio (%) for 2018 will be:
= Net income/Net sales
= 6370/91000
= 0.07
= 7%
An improvement of (7% - 6.95%) = 0.05% occurs in net profit.
2. Asset turnover for the year ended 2017 will be:
Net sales/Average total assets
= 89500/64400
= 1.39
= 139%
Asset turnover for the year ended 2018 will be:
Net sales/Average total assets
= 91000/65000
= 1.4
= 140%
There's an improvement in the asset turnover in 2018.
3. Return on assets for 2017 will be:
= Net income/Average total asset
= 6220/64400
= 9.66%
Return on assets for 2018 will be:
= Net income/Average total asset
= 6370/65000
= 9.80%
An improvement in return on total assets of (9.80% - 9.66%) = 0.14% occurs.
Both component-net profit margin ratio or asset turnover- are responsible for the change in the company's return on assets.
