The analysis of return on invested capital (ROIC) between 2014 and 2019 reveals a period of initial operational expansion followed by a phase of relative stabilization in capital efficiency.

Net Operating Profit After Taxes (NOPAT)

A substantial increase in profitability is observed between 2014 and 2015, where NOPAT rose from 3,086 million US$ to 5,501 million US$. Following this surge, earnings remained relatively stable, reaching a peak of 5,934 million US$ in 2018 before experiencing a slight contraction to 5,719 million US$ in 2019.

Invested Capital

Invested capital experienced significant growth during the first three years of the period, rising from 55,001 million US$ in 2014 to a peak of 85,356 million US$ in 2016. Subsequent years show a trend of capital reduction and stabilization, with the figure declining to 76,485 million US$ in 2017 and remaining relatively flat through 2019, ending at 77,429 million US$.

Return on Invested Capital (ROIC)

ROIC demonstrated a general upward trajectory over the six-year period, moving from 5.61% in 2014 to a peak of 7.78% in 2018. The fluctuations in this ratio reflect the interplay between expanding NOPAT and the volatility of the invested capital base. The decline to 7.39% in 2019 correlates with the marginal decrease in NOPAT, indicating a slight reduction in the efficiency of capital deployment toward the end of the observed timeframe.

The return on invested capital (ROIC) exhibited a general upward trajectory between 2014 and 2018, increasing from 5.61% to a peak of 7.78%, before experiencing a moderate decline to 7.39% in 2019. This overall performance reflects a complex interplay between declining operational profitability, improving asset utilization, and a decreasing cash tax burden.

Operating Profit Margin (OPM)

A volatile and generally downward trend is observed in the operating profit margin. After peaking at 6.93% in 2015, the margin fluctuated before falling to its lowest point of 4.79% in 2019. This compression indicates a reduction in operational efficiency or increased operating costs relative to revenue over the analyzed period.

Turnover of Capital (TO)

The turnover of capital demonstrates a consistent improvement in efficiency. Following a dip to 1.28 in 2015, the ratio climbed steadily to 1.77 by 2019. This upward trend suggests an increasing effectiveness in generating revenue from the invested capital base, which served as a primary counterbalance to the decline in profit margins.

Effective Cash Tax Rate Impact

The value representing 1 minus the effective cash tax rate showed a significant overall increase, rising from 64.39% in 2014 to 87.31% in 2019. This progression indicates a reduction in the effective cash tax burden over time, providing a persistent positive contribution to the final ROIC calculation.

ROIC Decomposition Synthesis

The analysis reveals that the growth in ROIC through 2018 was driven by gains in capital turnover and tax efficiencies rather than operational margin expansion. By 2019, the continued erosion of the operating profit margin began to outweigh the concurrent improvements in capital turnover and tax advantages, resulting in a contraction of the overall return on invested capital.

Between 2014 and 2019, a divergence is observed between revenue growth and operational efficiency. While top-line sales expanded consistently throughout the period, the operating profit margin experienced an overall contraction, indicating that cost increases outpaced revenue gains.

Revenue Trajectory

Sales demonstrated a sustained upward trend, growing from US$ 76,392 million in 2014 to US$ 136,866 million in 2019. This indicates a significant expansion in the scale of operations over the six-year timeframe.

Net Operating Profit Before Taxes (NOPBT)

NOPBT exhibited volatility and failed to mirror the steady growth of sales. After peaking at US$ 7,657 million in 2018, the figure declined to US$ 6,550 million in 2019, despite the company achieving its highest sales volume in that same year.

Operating Profit Margin (OPM) Trends

The operating profit margin reached a peak of 6.93% in 2015 before entering a general decline. The margin fell to 4.79% by 2019, marking the lowest point in the observed period. This downward progression highlights a steady erosion of operating profitability, suggesting a decrease in the company's ability to convert sales into operating profit.

A consistent expansion in revenue was observed from 2014 through 2019, coinciding with an initial surge and subsequent optimization of the invested capital base. This dynamic resulted in a strengthening of the capital turnover ratio over the latter half of the period.

Sales Growth

Revenue demonstrated a steady upward trajectory, increasing from US$ 76,392 million in 2014 to US$ 136,866 million by 2019. The most significant growth occurred between 2014 and 2015, where sales increased by approximately 35%.

Invested Capital Trends

Invested capital experienced a sharp increase between 2014 and 2016, rising from US$ 55,001 million to a peak of US$ 85,356 million. Following 2016, a contraction was observed, with the capital base stabilizing between US$ 76,286 million and US$ 77,429 million from 2017 to 2019.

Turnover of Capital (TO) Efficiency

The capital turnover ratio initially declined to 1.28 in 2015, as the increase in invested capital momentarily outpaced revenue growth. However, from 2016 onward, the ratio entered a period of consistent improvement, rising from 1.37 to 1.77 by 2019. This upward trend indicates enhanced operational efficiency, as the company successfully generated higher sales volumes while reducing and stabilizing the amount of capital employed.

The effective cash tax rate (CTR) exhibited a significant overall downward trajectory between 2014 and 2019, characterized by an initial sharp decline followed by a period of relative stability and a final substantial contraction.

Effective Cash Tax Rate Trends

The CTR began at a peak of 35.61% in 2014 before falling sharply to 23.25% in 2015. For the subsequent three fiscal years, the rate fluctuated within a narrow corridor, ranging from a high of 27.66% in 2016 to a low of 22.50% in 2018. The period concluded with a dramatic reduction in 2019, where the CTR reached its lowest observed level of 12.69%.

Correlation Between Profitability and Tax Outflows

Net operating profit before taxes (NOPBT) showed a general upward trend for much of the period, rising from 4,792 million in 2014 to a peak of 7,657 million in 2018. During this growth phase, cash operating taxes remained relatively stagnant, oscillating between 1,667 million and 1,856 million. This disconnect between rising operating profits and flat cash tax payments drove the steady decrease in the effective tax rate through 2018.

Analysis of the 2019 Fiscal Contraction

The 2019 fiscal year is marked by a disproportionate collapse in cash tax obligations relative to operating performance. While NOPBT experienced a moderate decline of approximately 14.4% compared to the previous year, cash operating taxes decreased by 51.8%, falling from 1,723 million to 831 million. This precipitous drop in tax outflows resulted in the CTR falling to 12.69%, indicating a significant reduction in the cash tax burden relative to the generated operating profit.
