Net Interest Income

The primary source of the Company’s revenue is net interest income. Net interest income is the difference between interest income and fees on earning assets, such as loans and securities, and interest expense on the liabilities to fund those assets, including interest-bearing deposits and other borrowings. The amount of net interest income is affected by both changes in the level of interest rates, and the amount and composition of earning assets and interest bearing liabilities.
