³ 2018 Calculation
Common equity (market value) = Share price × No. shares of common stock outstanding
= 31.40 × 872,542,842

Common Equity (Market Value): The common equity experienced fluctuations over the period. Starting at 36,638 million US dollars in 2014, it declined significantly to 26,909 million in 2015. This was followed by a substantial rebound to 47,577 million in 2016. Subsequent years saw a decline again, with values falling to 40,858 million in 2017 and 27,398 million in 2018.
Total Equity: Total equity mirrored the trend of common equity closely, beginning at 36,669 million US dollars in 2014. It decreased to 26,942 million in 2015, then increased sharply to 47,616 million in 2016. Afterward, it declined to 40,885 million in 2017 and further dropped to 27,420 million in 2018. The close alignment of common equity and total equity values suggests minimal influence of preferred equity or other equity components during these years.
Total Equity and Debt: Total equity and debt showed a rising trend from 44,523 million US dollars in 2014 to a peak of 60,000 million in 2016, followed by subsequent declines to 51,827 million in 2017 and then to 37,877 million in 2018. This indicates an overall reduction in combined capital financing after 2016, possibly due to repayments or reduction in liabilities and equity financing.
Enterprise Value (EV): The enterprise value followed a similar pattern as total equity and debt, initiating at 42,232 million US dollars in 2014, decreasing sharply to 32,211 million in 2015. It peaked at 55,991 million in 2016, then decreased again to 49,490 million in 2017, and dropped further to 35,869 million in 2018. These fluctuations could reflect changes in market valuation, debt levels, and overall business performance during the period.
