You will need to maintain a certain level of Investor PR to maintain your firm's profile, since it decays over time. About half of your accumulated Investor PR investment from the previous period will carry over. Combined with your expenditure in the current period, this will generate an Investor PR Index for the current period. The curve below shows how this cumulative expenditure translates into the Investor PR Index - which is used as a share price multiplier.
