The analysis of the financial structure over the five-year period reveals several noteworthy trends and shifts in the composition of liabilities and stockholders’ equity.

Current Liabilities

Current liabilities as a percentage of total liabilities and stockholders’ equity showed considerable fluctuation. Starting at 16.46% in 2016, they decreased to 14.19% in 2017, sharply increased to 25.92% in 2018, then declined significantly to 9.09% in 2019, and rose again to 16.4% in 2020. Within this category, accounts payable and contract liabilities consistently decreased as a proportion of total financing from 2016 through 2019, with a slight rebound in 2020. Accrued compensation expenses peaked in 2017, then generally declined through 2020. Accrued taxes payable exhibited a moderate upward trend until 2019, followed by a decline in 2020. Operating lease liabilities, introduced in 2019, remained relatively stable thereafter.

Long-Term Liabilities

Long-term liabilities showed a declining trend from 29.48% in 2016 to 17.95% in 2018, recovering somewhat to 27.86% in 2019 before decreasing again to 21.71% in 2020. Notably, long-term debt excluding the current portion decreased steadily from 24.48% in 2016 to 8.87% in 2020, highlighting a reduction in this debt over time. The current portion of long-term debt rose sharply in 2018 to 15.91%, dropped out of reported values in 2019, then reappeared at 6.74% in 2020. The introduction and growth of operating lease liabilities excluding the current portion in 2019 and 2020 represented a new element in long-term obligations, comprising around 9.5% and 8.85% respectively. Other long-term liabilities fluctuated, peaking at 6.85% in 2017 and reaching a low in 2019 before increasing again in 2020.

Total Liabilities

Total liabilities decreased from 45.94% in 2016 to their lowest point of 36.95% in 2019, then rose to 38.11% in 2020, indicating a reduction in leverage followed by a modest increase.

Stockholders’ Equity

Stockholders’ equity increased steadily over the period, from 53.04% in 2016 to a peak of 63.05% in 2019, slightly falling to 61.89% in 2020. This increase was driven primarily by the growth in retained earnings, which rose consistently from 34.7% in 2016 to 62.27% in 2020, reflecting accumulated profitability. Additional paid-in capital decreased from 63.86% in 2016 to 47.28% in 2018, then showed a gradual recovery to 50.3% by 2020. Treasury stock represented a significant negative component throughout the period, increasing in magnitude from -47.25% in 2016 to -50.73% in 2020, which indicates the repurchase of shares or related stock activities affecting equity negatively. The common stock component remained stable and negligible in proportion during the period. Accumulated other comprehensive income/loss remained close to zero, with slight improvement from a negative balance in earlier years to a small positive figure in 2019 and 2020.

Noncontrolling and Redeemable Interests

Redeemable noncontrolling interests were present only in the early years of the period, peaking at 4.18% in 2017 before disappearing in later years. Noncontrolling interests appeared irregularly and represented a minor share throughout.

In summary, the financial structure shows a shift toward increased reliance on equity financing, driven largely by growing retained earnings, accompanied by a reduction in long-term debt levels. Current liabilities exhibit volatility, influenced by changes in specific items such as long-term debt current portions and lease liabilities. The introduction of lease obligations in 2019 reflects changes in accounting or financing structures. Treasury stock trends indicate ongoing share repurchases or similar equity reductions. Overall, the company’s balance between liabilities and equity has tended to favor equity over the analyzed period, suggesting an emphasis on strengthening the equity base and reducing debt exposure.
