Purpose: The objective of this research is to analyze the effect of corporate governance practices on firms' financial performance, as measured by comprehensive income.Design/methodology/approach: Using a sample of 237 firms from the S&P 500 Index during the years 2004 to 2009, multivariate statistical analyses are conducted in order to confirm our main hypothesis.
Findings:The results indicate that having high levels of corporate governance culture has a positive impact on a measure of firms' financial performance, namely comprehensive income. Furthermore, they indicate a positive correlation between the percentage of external directors and financial performance, and a negative relationship between number of board meetings and financial performance.Originality/value: The main contribution of this research is that good corporate governance strategies deliver superior financial performance for businesses in terms of comprehensive income. This serves as a method of value creation, which is the ultimate goal of a business. In addition to the use of comprehensive income as an indicator of financial performance, a unique measure of corporate governance level is tested.
