Any member receiving retirement benefits from the System as of

June 30, 1999, who continues to receive benefits on or after July 1,

($1,283.00) by two percent (2%);

2. Multiply the sum of paragraph 1 by the number of years of

credited service of the member;

3. Divide the sum of paragraph 2 by twelve (12) and this shall

be the increase in the monthly retirement benefit; and

4. This increase shall be adjusted to reflect any options

selected by the member at the time of retirement.
