The data reveals notable fluctuations and trends in net earnings, stockholders' equity, and return on equity (ROE) over the observed period.

Net Earnings

The net earnings show a general upward trend from 2005 to 2021 with some variability. Starting at approximately $1.06 billion in 2005, earnings increased notably to $1.55 billion in 2006 before experiencing a decline and subsequent recovery phases. From 2007 through 2014, net earnings fluctuated moderately within the range of about $1.13 billion to $1.52 billion. Post-2014, net earnings entered a strong growth phase, reaching approximately $2.60 billion by 2021, representing more than a doubling compared to the 2005 figure.

Stockholders’ Equity

Stockholders' equity exhibited greater volatility compared to net earnings. It started at $5.78 billion in 2005 and remained relatively stable through 2009 with slight fluctuations. From 2010, equity rose to peak above $6.6 billion in 2013. However, in the subsequent years from 2014 through 2018, there was a marked decline, bottoming out near $3.46 billion in 2018, indicating significant equity reduction during this period. Following this trough, equity rebounded sharply by 2019 and stabilized around $5.67 billion by 2021; nonetheless, this value is still moderately below the highest levels observed earlier in the decade.

Return on Equity (ROE)

ROE demonstrated an increasing trend during the period. Initially at 18.25% in 2005, it improved steadily, surpassing 20% from 2007 onward. A substantial rise occurred after 2010, with ROE reaching above 30% in 2014 and continuing to climb to peak levels near 46.85% in 2018. Despite some minor fluctuations, ROE remained elevated above 40% through 2021. This trend suggests improved efficiency in generating earnings relative to equity, particularly evident during the period of declining equity between 2014 and 2018.

Interrelations and Insights

The substantial decline in stockholders' equity between 2013 and 2018, combined with rising net earnings and sharply increasing ROE, could imply significant capital structure changes such as share repurchases, dividend distributions, or other equity adjustments affecting the equity base. The persistence of strong net earnings growth alongside elevated ROE indicates enhanced profitability and capital utilization efficiency in recent years. The rebound of equity after 2018 may reflect a restoration of capital reserves or new equity issuance accompanying continued earnings growth.
