S&P Global Market Intelligence ranked the best-performing regional banks using six core financial metrics that focus on profitability, asset quality, and loan growth for the year ended Dec. 31, 2016. The metrics included return on average tangible common equity, net charge-offs as a percentage of average loans, adjusted Texas ratio, efficiency ratio, net interest margin and loan growth.
For each of the six metrics, S&P Global Market Intelligence measured each company's standard deviation from the mean of all eligible companies. The standard deviations were given equal weights and then added together to calculate a performance score the each company. Caps and floors were also implemented to prevent significant outliers from skewing a company's rank.
For the purposes of this ranking, S&P Global Market Intelligence defined regional banks as those top-tier consolidated banks and thrifts with total assets between $10 to $50 billion. S&P Global Market Intelligence chose the $50 billion asset cutoff to separate smaller regional banks from larger superregionals that may be subject to greater regulatory scrutiny, including Comprehensive Capital Analysis and Review.
