5.   Comprehensive Income
 
       Accounting principles generally accepted in the United States of America require that recognized revenue, expenses, gains and losses be included in net income.  Although certain changes in assets and liabilities such as unrealized gains and losses on available for sale securities, are reported as a separate component of the equity section of the balance sheet, such items, along with net income, are components of comprehensive income.  The components of other comprehensive income and related tax effects are as follows:
