The analysis of income tax components between 2017 and 2021 reveals a significant volatility in the early period followed by a period of relative stabilization and a subsequent increase in tax obligations.

Current Tax Trends

Current tax expenses exhibited a fluctuating pattern over the five-year period. After an initial increase from 583 million US$ in 2017 to 630 million US$ in 2018, a downward trend was observed, with expenses reaching a low of 375 million US$ in 2020. This decline was reversed in 2021, when current taxes surged to 689 million US$, the highest value recorded in the analyzed period.

Deferred Tax Analysis

A substantial anomaly is noted in 2017, where deferred taxes recorded a benefit of 2,859 million US$. Following this event, deferred taxes transitioned to a positive expense, remaining relatively stable between 142 million US$ and 330 million US$ from 2018 through 2021. This shift indicates a fundamental change in the timing differences between accounting and taxable income after the 2017 fiscal year.

Total Income Tax Expense Performance

The total income tax position shifted from a net tax benefit of 2,276 million US$ in 2017 to a consistent net expense in subsequent years. Total taxes remained within a range of 517 million US$ to 873 million US$ from 2018 to 2021. The peak expense occurred in 2021 at 873 million US$, driven primarily by the increase in current tax obligations.

The overarching pattern indicates that while the 2017 fiscal year was characterized by an extraordinary tax benefit, the subsequent years reflect a normalized tax environment with a notable increase in the tax burden toward the end of the period.

The effective income tax rate exhibited significant volatility between 2017 and 2021, primarily driven by major legislative shifts in federal tax policy and one-time reform adjustments. Following a period of extreme fluctuation in 2017, the rate transitioned into a state of relative stability from 2018 through 2021.

Federal Statutory Tax Rate Transition

A substantial reduction in the federal income statutory tax rate is observed, dropping from 35.00% in 2017 to 21.00% in 2018. This lower rate remained constant through the end of the analysis period in 2021, establishing a new baseline for the company's tax obligations.

Impact of Tax Reform

The 2017 fiscal year was characterized by a significant negative adjustment attributed to tax reform, totaling -106.50%. When combined with equity in earnings related to tax reform of -1.20%, the overall effective income tax rate for 2017 was reduced to -72.80%, representing a one-time anomalous event that deviates from standard operational tax trends.

Analysis of Rate Adjustments

State income taxes provided a consistent upward adjustment to the federal rate, fluctuating within a narrow range between 2.80% and 3.50%. Conversely, excess tax benefits on stock-based compensation and other net items consistently acted as downward pressures on the effective rate. Excess tax benefits on stock-based compensation ranged from -0.60% to -1.50%, while other net adjustments varied from -0.70% to -2.40%.

Normalized Effective Income Tax Rate Trends

Excluding the 2017 reform impact, the effective income tax rate remained stable, oscillating between 20.40% and 23.10%. After the initial drop to 23.10% in 2018, the rate declined slightly to 22.00% in 2019 and reached a period low of 20.40% in 2020, before increasing to 22.50% in 2021.

The overall net deferred tax position exhibits a consistent trend toward increasing liabilities over the five-year period from 2017 to 2021. The net deferred income taxes shifted from a liability of 6,324 million US dollars in 2017 to 7,165 million US dollars by 2021, representing a deepening of the net liability position.

Deferred Tax Asset Trends

Gross deferred tax assets experienced an upward trajectory from 366 million US dollars in 2017 to a peak of 513 million US dollars in 2019, followed by a moderate decline to 461 million US dollars in 2021. The most significant contributor to these assets was compensation and benefits, although this specific component saw a steady decline after 2018. Accruals for casualty and other claims showed a general increase, stabilizing around 92 million US dollars in the final two years of the period.

Valuation Allowance and Net Asset Value

A consistent increase in the valuation allowance is observed, rising from 44 million US dollars in 2017 to 60 million US dollars in 2021. This steady growth in the allowance offset a portion of the gross assets, resulting in net deferred tax assets that peaked in 2019 at 459 million US dollars before receding to 401 million US dollars by 2021.

Deferred Tax Liability Drivers

Deferred tax liabilities grew steadily from 6,646 million US dollars in 2017 to 7,566 million US dollars in 2021. The primary driver of this increase is the property component, which expanded from a liability of 6,212 million US dollars to 7,016 million US dollars over the period. This suggests a growing timing difference between book and tax accounting related to property assets, likely driven by accelerated depreciation.

Net Deferred Tax Position

The widening gap between deferred tax assets and liabilities resulted in an increase in the net deferred tax liability. The net position deteriorated by approximately 841 million US dollars between 2017 and 2021, driven primarily by the growth in property-related tax liabilities which outweighed the fluctuations in deferred tax assets.

A consistent upward trend in net deferred tax liabilities is observed over the five-year period ending December 31, 2021. The balance has increased annually, reflecting a steady accumulation of future tax obligations relative to deferred tax assets.

Growth Trajectory

Net deferred tax liabilities rose from 6,324 million US dollars in 2017 to 7,165 million US dollars by the end of 2021, representing a total increase of approximately 13.3% over the analyzed period.

Annual Progression

The increase occurred incrementally each year, with the most significant single-year growth observed between 2018 and 2019, when liabilities increased by 355 million US dollars. Subsequent growth remained positive, though the rate of increase fluctuated slightly.

Financial Implications

The continuous rise in the net deferred tax liability position indicates a persistent widening of temporary differences between financial reporting and tax accounting, often associated with factors such as accelerated depreciation or other timing-related tax benefits.

The removal of deferred tax obligations results in a significant reconfiguration of the balance sheet, effectively neutralizing the impact of non-cash tax liabilities on the company's financial position. This adjustment reveals a substantial gap between reported and adjusted figures, indicating that deferred taxes constitute a major component of the total liability structure.

Impact on Total Liabilities

A consistent reduction in total liabilities is observed upon the removal of deferred taxes. The variance between reported and adjusted liabilities grew steadily from 6,324 million US dollars in 2017 to 7,165 million US dollars in 2021. This indicates an upward trend in the accumulation of deferred tax liabilities over the five-year period.

Impact on Stockholders' Equity

The adjustment creates a mirrored effect on stockholders' equity, where the removal of liabilities results in a significant increase in equity. Although reported stockholders' equity showed a continuous decline from 16,359 million US dollars in 2017 to 13,641 million US dollars in 2021, the adjusted equity remained markedly higher, ranging from 22,683 million US dollars to 20,806 million US dollars.

Net Income Variance

The divergence between reported and adjusted net income suggests that deferred tax accounting significantly influenced reported profitability. In 2017, reported net income exceeded adjusted net income by 2,859 million US dollars. Conversely, from 2018 to 2021, adjusted net income was generally higher than reported net income, with the most pronounced difference occurring in 2021, where adjusted net income exceeded reported figures by 184 million US dollars.

Overall, the data demonstrates that while reported liabilities are increasing and reported equity is decreasing, the adjusted figures provide a view of the company's capital structure that excludes the distorting effects of deferred tax accounting, revealing a more stable equity base and a lower liability profile.

The removal of deferred taxes reveals significant discrepancies between reported financial ratios and adjusted performance metrics, suggesting that tax accounting creates substantial volatility and distorts the perception of the company's underlying financial health. The adjusted figures provide a more normalized view of profitability, leverage, and return metrics over the five-year period ending December 31, 2021.

Net Profit Margin

Reported net profit margins exhibit extreme volatility, specifically the outlier of 51.22% in 2017. In contrast, the adjusted net profit margin demonstrates a more stable and positive trajectory, rising from 24.12% in 2017 to 28.62% in 2021. This indicates that the reported fluctuations are primarily driven by deferred tax adjustments rather than operational performance.

Financial Leverage

A consistent upward trend is observed in both reported and adjusted leverage ratios from 2017 to 2021. However, the adjusted leverage is systematically lower than the reported leverage throughout the entire period. This suggests that deferred tax liabilities significantly inflate the reported financial gearing, whereas the adjusted ratios present a more conservative view of the capital structure.

Return on Equity (ROE)

Reported ROE shows substantial variance, peaking at 33.03% in 2017 before declining and recovering to 22.03% in 2021. The adjusted ROE is consistently lower and less volatile, moving from 11.22% in 2017 to 15.33% in 2021. The gap between the two metrics suggests that deferred tax impacts artificially amplify the returns attributed to equity holders in the reported statements.

Return on Assets (ROA)

Reported ROA experienced a sharp decline following 2017, dropping from 15.13% to a low of 5.30% in 2020. Conversely, the adjusted ROA remained more resilient and stable. Notably, from 2018 through 2021, the adjusted ROA consistently outperformed the reported ROA, indicating that the removal of deferred tax elements provides a more favorable and stable representation of asset utilization efficiency.

An analysis of the financial performance between 2017 and 2021 reveals a significant divergence between reported and adjusted profitability metrics. While reported figures exhibit high volatility, the adjusted metrics provide a more stable representation of the underlying operational profitability over the five-year period.

Adjusted Net Profit Margin Trends

The adjusted net profit margin demonstrates a general upward trajectory, increasing from 24.12% in 2017 to 28.62% in 2021. Despite a temporary contraction to 22.01% in 2020, the margin recovered strongly in 2021, reaching its peak for the analyzed period. This suggests an improvement in operational efficiency and cost management when non-recurring items are excluded.

Comparison of Reported versus Adjusted Net Income

A notable discrepancy is observed in 2017, where reported net income of US$ 5,404 million far exceeded adjusted net income of US$ 2,545 million. From 2018 through 2021, the pattern reversed, with adjusted net income consistently exceeding reported net income. This shift indicates that while 2017 was bolstered by significant one-time gains or tax benefits, subsequent years were impacted by non-recurring expenses or losses that depressed reported earnings.

Analysis of Profitability Volatility

Reported net profit margins showed extreme fluctuation, dropping sharply from 51.22% in 2017 to 23.27% in 2018, and fluctuating between 20.56% and 26.97% thereafter. In contrast, the adjusted net profit margin remained within a narrower range of 22.01% to 28.62%. The stability of the adjusted margin indicates that the primary drivers of volatility in reported earnings were non-operational or non-recurring in nature.

Impact of the 2020 Fiscal Year

A synchronized decline is observed in both reported and adjusted metrics during 2020. Reported net income fell to US$ 2,013 million and adjusted net income decreased to US$ 2,155 million. The adjusted net profit margin also hit a period low of 22.01%, suggesting a broad systemic impact on profitability during that year before a robust recovery in 2021.

A consistent decline in stockholders' equity and a simultaneous increase in financial leverage were observed between 2017 and 2021. This trend indicates a progressive shift in the capital structure toward higher relative debt levels over the five-year period.

Equity Trends

Reported stockholders' equity decreased steadily from 16,359 million USD in 2017 to 13,641 million USD by 2021. Adjusted stockholders' equity followed a similar overall downward trajectory, declining from 22,683 million USD to 20,806 million USD, despite a marginal increase in 2019. The adjusted equity figures remained substantially higher than reported values throughout the period, indicating a significant variance between reported and adjusted capital bases.

Financial Leverage Patterns

Reported financial leverage rose consistently every year, moving from 2.18 in 2017 to 2.82 in 2021. Adjusted financial leverage mirrored this upward trend, increasing from 1.57 to 1.85. While both metrics confirm an escalation in leverage, the adjusted ratio remained consistently lower, presenting a more moderated view of the entity's financial risk.

Comparative Leverage Analysis

The rate of increase in reported financial leverage exceeded that of adjusted financial leverage. Reported leverage increased by 0.64 points over the period, while adjusted leverage increased by 0.28 points. This divergence suggests that the adjustments made to stockholders' equity served to dampen the volatility and the perceived intensity of the increasing leverage trend.

The financial results between 2017 and 2021 exhibit a notable divergence between reported and adjusted performance metrics, particularly concerning profitability and shareholder equity.

Net Income Trends

Reported net income demonstrated significant volatility, peaking in 2017 at US$ 5,404 million before declining to a period low of US$ 2,013 million in 2020, followed by a recovery to US$ 3,005 million in 2021. Conversely, adjusted net income followed a more stable trajectory, increasing from US$ 2,545 million in 2017 to US$ 3,052 million in 2019, before a temporary contraction in 2020 and a subsequent rise to a five-year peak of US$ 3,189 million in 2021.

Equity Base Analysis

A consistent downward trend is observed across both equity measures. Reported stockholders’ equity decreased steadily from US$ 16,359 million in 2017 to US$ 13,641 million in 2021. Adjusted stockholders’ equity followed a similar pattern of erosion, declining from US$ 22,683 million in 2017 to US$ 20,806 million in 2021.

Return on Equity (ROE) Interpretation

Reported ROE experienced high variance, falling from 33.03% in 2017 to 13.61% in 2020, before rebounding to 22.03% in 2021. Adjusted ROE remained consistently lower and less volatile than the reported figures, moving from 11.22% in 2017 to a peak of 15.33% in 2021. The persistent gap between the two metrics is driven by the significantly higher valuation of adjusted stockholders’ equity compared to reported equity, which serves to moderate the adjusted return percentages.

Overall, while the reported figures suggest higher volatility and higher nominal returns, the adjusted metrics reveal a more conservative and stabilized growth pattern in profitability and a gradual contraction of the equity base.

The financial performance from 2017 to 2021 exhibits a significant divergence between reported and adjusted metrics, particularly in the initial year of the period. While reported figures show substantial volatility, adjusted figures provide a more stabilized view of operational efficiency and profitability.

Net Income Trends

Reported net income experienced a sharp decline from US$ 5,404 million in 2017 to US$ 2,666 million in 2018, remaining relatively flat through 2019 before reaching a period low of US$ 2,013 million in 2020. A recovery followed in 2021, with income rising to US$ 3,005 million. Conversely, adjusted net income demonstrated a more consistent growth trajectory between 2017 and 2019, increasing from US$ 2,545 million to US$ 3,052 million. Adjusted net income also declined in 2020 to US$ 2,155 million before reaching its five-year peak of US$ 3,189 million in 2021.

Return on Assets (ROA) Analysis

Reported ROA shows extreme variance, starting at 15.13% in 2017 and falling precipitously to 7.36% in 2018. This suggests that the 2017 reported results were heavily influenced by non-recurring items or one-time gains. Adjusted ROA provides a more stable perspective, increasing steadily from 7.13% in 2017 to 8.05% in 2019. Both reported and adjusted ROA declined in 2020, with adjusted ROA hitting a low of 5.68%, before rebounding strongly to 8.28% in 2021.

Comparative Performance Insights

The discrepancy between reported and adjusted ROA is most pronounced in 2017, where a gap of 8 percentage points exists. In subsequent years, adjusted ROA consistently exceeded reported ROA, indicating that non-recurring expenses or adjustments typically weighed down reported earnings. The simultaneous dip in both reported and adjusted metrics during 2020 indicates a systemic impact on assets and income during that period, while the 2021 results demonstrate a robust recovery in operational efficiency.
