For new investments we determine the number of shares based on the stock price and the account value at the time the stock is presented for vote.  The investment must be in the range of 15% to 30% of the account value, and we prefer to invest 20% to 25% of the account.  We buy round lots of 100 shares when possible.  For stock prices that are very high we can buy odd lots.  The web site automatically calculates the number of shares using the following method:


limit = maximum approved purchase price per share
shares = 25% of the account value divided by the limit, rounded down to an even multiple of 100
investment = shares multiplied by the limit

If the investment is less than 20% of the account value
      shares = 30% of the account value divided by the limit, rounded down to an even multiple of 100
      investment = shares multiplied by the limit

      If the investment is less than 15% of the account value
           shares = 25% of the account value divided by the limit, rounded down to an even multiple of 10
           investment = shares multiplied by the limit

           If the investment is less than 20% of the account value
                shares = 30% of the account value divided by the limit, rounded down to an even multiple of 10
                investment = shares multiplied by the limit

                If the investment is less than 15% of the account value
                     shares = 25% of the account value divided by the limit, truncating any fraction
                     investment = shares multiplied by the limit

                     If the investment is less than 20% of the account value
                          shares = 30% of the account value divided by the limit, truncating any fraction
                          investment = shares multiplied by the limit

                          If the investment is less than 15% of the account value
                               Do not allow the stock purchase
