(g) Efficiency ratio is calculated by dividing total other expense by the sum of fully taxable equivalent net interest income and other income. Fully taxable equivalent net interest income reconciliation is shown assuming a 21% corporate federal income tax rate. Additionally, net interest margin is calculated on a fully taxable equivalent basis by dividing fully taxable equivalent net interest income by average interest earning assets, in each case during the applicable period.
