Decomposing ROE involves expressing net income divided by shareholders’ equity as the product of component ratios.
Two-Component Disaggregation of ROE
Based on: 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31), 10-K (reporting date: 2016-12-31), 10-K (reporting date: 2015-12-31).
An analysis of the financial performance from 2015 to 2019 reveals a stark divergence between operational asset efficiency and the overall return on equity. While the return on assets experienced significant volatility and a general decline from its 2015 peak, the return on equity grew exponentially, driven almost exclusively by an aggressive increase in financial leverage.
- Return on Assets (ROA)
- A sharp contraction is observed between 2015 and 2016, where ROA fell from 14.12% to 3.23%. Although a moderate recovery occurred through 2018, reaching 8.05%, the metric declined again to 5.08% by 2019. This suggests that the underlying profitability generated per unit of asset remained substantially lower than 2015 levels and lacked a sustained upward trajectory.
- Financial Leverage
- The leverage ratio exhibits a consistent and accelerating upward trend. Starting at 4.51 in 2016, the ratio increased to 6.42 in 2017 and 10.65 in 2018, before experiencing a substantial surge to 35.63 by 2019. This trajectory indicates a significant shift in the capital structure, characterized by an increasing reliance on debt or a significant reduction in shareholders' equity.
- Return on Equity (ROE)
- ROE demonstrates an exponential increase, rising from 14.56% in 2016 to 181.08% by 2019. The two-component disaggregation confirms that this growth is not a result of improved operational efficiency, as ROA remained volatile and relatively low. Instead, the expansion of ROE is a direct result of the escalating financial leverage multiplier, which amplified the modest ROA to produce high nominal returns for shareholders, simultaneously increasing the financial risk profile.

Three-Component Disaggregation of ROE
Based on: 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31), 10-K (reporting date: 2016-12-31), 10-K (reporting date: 2015-12-31).
The Return on Equity (ROE) exhibited exponential growth between 2016 and 2019, rising from 14.56% to 181.08%. A disaggregation of this metric reveals that the primary driver of this increase was a dramatic escalation in financial leverage rather than improvements in operational efficiency or profit margins.
- Net Profit Margin
- Profitability remained relatively volatile but stable within a narrow range for most of the period. After a decline to 4.57% in 2016, the margin recovered to 5.99% in 2017 and peaked at 9.19% in 2018 before normalizing to 6.07% in 2019. While the 2018 spike provided a temporary boost to returns, the overall margin trend does not account for the magnitude of the ROE expansion.
- Asset Turnover
- A significant contraction in asset turnover occurred after 2015, falling from 2.38 to 0.71 in 2016. The ratio remained depressed throughout the remainder of the period, fluctuating between 0.84 and 0.96. This downward shift indicates a reduction in the efficiency of assets in generating revenue, acting as a drag on the overall ROE.
- Financial Leverage
- The most prominent trend is the aggressive increase in financial leverage, which rose consistently from 4.51 in 2016 to 35.63 by 2019. The acceleration was particularly acute between 2018 and 2019, where the leverage ratio more than tripled. This indicates a substantial increase in the use of debt relative to equity to finance the asset base.
- ROE Synthesis
- The DuPont analysis confirms that the surge in ROE was fundamentally driven by the multiplier effect of financial leverage. Despite a decline in asset turnover and a relatively stagnant net profit margin, the exponential increase in leverage amplified the return on equity, shifting the company's return profile toward a high-leverage strategy.

Five-Component Disaggregation of ROE
Based on: 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31), 10-K (reporting date: 2016-12-31), 10-K (reporting date: 2015-12-31).
Return on Equity (ROE) experienced an exponential increase between 2016 and 2019, rising from 14.56% to 181.08%. This trajectory indicates a fundamental shift in the drivers of shareholder returns, moving from operational performance toward aggressive financial engineering.
- Operational Efficiency
- The EBIT Margin demonstrated volatility, peaking at 13.65% in 2017 before declining to 9.50% by 2019. Concurrently, Asset Turnover witnessed a sharp contraction after 2015, falling from 2.38 to a range between 0.71 and 0.96 throughout the subsequent four years. These trends suggest that the growth in ROE was not supported by improvements in operating profitability or asset utilization.
- Financial Leverage and Interest Burden
- Financial Leverage emerged as the primary catalyst for the surge in ROE, escalating from 4.51 in 2016 to 35.63 in 2019. This dramatic increase signifies a substantial reliance on debt or a significant reduction in equity. The Interest Burden remained relatively stable but trended slightly downward from 0.88 in 2015 to 0.80 in 2019, indicating that interest expenses consumed a progressively larger portion of operating income.
- Tax Burden
- The Tax Burden ratio exhibited significant fluctuations, dropping to a period low of 0.48 in 2017 before recovering to 0.80 by 2019. This variability suggests changes in the effective tax rate or the impact of one-time tax adjustments during the observed timeframe.
In summary, the disproportionate growth in Financial Leverage outweighs the declines observed in Asset Turnover and EBIT Margin, resulting in an amplified Return on Equity that is primarily driven by capital structure rather than operational excellence.

Two-Component Disaggregation of ROA
Based on: 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31), 10-K (reporting date: 2016-12-31), 10-K (reporting date: 2015-12-31).
The Return on Assets (ROA) exhibited significant volatility between 2015 and 2019, characterized by a sharp contraction followed by a partial recovery and a subsequent decline. The overall trend suggests a fundamental shift in the drivers of asset productivity and profitability over the five-year period.
- Net Profit Margin
- Profitability demonstrated fluctuating performance, starting at 5.93% in 2015 and dipping to 4.57% in 2016. A strong upward trend was observed through 2018, where the margin reached a period peak of 9.19%, before retreating to 6.07% by 2019.
- Asset Turnover
- A substantial reduction in asset efficiency occurred between 2015 and 2016, with the ratio falling precipitously from 2.38 to 0.71. Following this drop, the ratio remained relatively stagnant, fluctuating within a narrow range between 0.84 and 0.96 for the remainder of the period.
- Return on Assets (ROA) Integration
- The precipitous decline in ROA from 14.12% in 2015 to 3.23% in 2016 was primarily driven by the collapse in asset turnover rather than the marginal decrease in profit margins. The subsequent recovery in ROA, which peaked at 8.05% in 2018, was largely supported by the expansion of the net profit margin, as asset turnover failed to return to 2015 levels. The final decline to 5.08% in 2019 resulted from a simultaneous compression in both profit margins and asset utilization.

Four-Component Disaggregation of ROA
Based on: 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31), 10-K (reporting date: 2016-12-31), 10-K (reporting date: 2015-12-31).
The Return on Assets (ROA) exhibited significant volatility between 2015 and 2019, starting at a peak of 14.12% before experiencing a sharp contraction to 3.23% in 2016. While a partial recovery was observed through 2018, reaching 8.05%, the metric declined again to 5.08% by the end of 2019. This fluctuation is the result of varying contributions from operational efficiency, asset utilization, and financial burdens.
- Asset Turnover
- The most substantial driver of the overall ROA decline was the precipitous drop in asset turnover, which fell from 2.38 in 2015 to 0.71 in 2016. The ratio remained suppressed for the remainder of the period, fluctuating between 0.71 and 0.96. This indicates a significant expansion of the asset base relative to revenue generation, which permanently lowered the baseline for asset productivity compared to the 2015 level.
- EBIT Margin
- Operational profitability demonstrated a non-linear trend, reaching a peak of 13.65% in 2017. This operational strength helped mitigate some of the losses in asset turnover during the 2017-2018 period. However, the margin contracted to 9.50% in 2019, returning to levels nearly identical to those seen in 2015.
- Tax Burden
- The tax burden showed considerable instability, particularly in 2017 when it dropped to 0.48, indicating a higher tax impact on pre-tax income. A subsequent recovery occurred in 2018 and 2019, with the ratio stabilizing at 0.81 and 0.80 respectively, reflecting an improvement in the proportion of earnings retained after taxes.
- Interest Burden
- The interest burden remained the most stable of the four components, although a gradual downward trajectory is observable. Starting at 0.88 in 2015, it declined to 0.80 by 2019, suggesting a slight increase in interest expenses relative to operating income over the five-year span.
The synthesis of these components reveals that the collapse in ROA during 2016 was primarily triggered by a collapse in asset turnover. Although improvements in the EBIT margin and tax burden provided a temporary lift to ROA in 2017 and 2018, the failure of asset turnover to return to 2015 levels, combined with a declining EBIT margin in 2019, resulted in a diminished overall return on assets by the end of the analyzed period.

Disaggregation of Net Profit Margin
Based on: 10-K (reporting date: 2019-12-31), 10-K (reporting date: 2018-12-31), 10-K (reporting date: 2017-12-31), 10-K (reporting date: 2016-12-31), 10-K (reporting date: 2015-12-31).
The net profit margin exhibited significant volatility between 2015 and 2019, characterized by an initial decline in 2016, a peak of 9.19% in 2018, and a subsequent contraction to 6.07% in 2019. This fluctuation in bottom-line profitability is the result of interacting trends across operating efficiency, tax obligations, and financing costs.
- Operating Performance (EBIT Margin)
- The EBIT margin demonstrated a non-linear trend, increasing from 9.82% in 2015 to a peak of 13.65% in 2017. However, a downward trajectory followed, with the margin receding to 9.50% by 2019. This indicates that while operational efficiency improved significantly in the middle of the period, these gains were largely eroded by 2019.
- Tax Burden
- The tax burden was the most volatile component of the net profit margin disaggregation. A significant decline to 0.48 in 2017 acted as a primary drag on net profitability during a year of peak operating performance. Conversely, a sharp increase to 0.81 in 2018 and 0.80 in 2019 indicates a substantial reduction in the effective tax rate, which bolstered net profit margins despite the subsequent decline in EBIT margins.
- Interest Burden
- The interest burden remained relatively stable from 2015 to 2018, fluctuating between 0.83 and 0.91. A noticeable decline to 0.80 occurred in 2019, suggesting that a larger portion of operating income was consumed by interest expenses relative to prior years, thereby contributing to the overall compression of the net profit margin in the final year of the analysis.
