 the performance of the Fund or any other account managed by that portfolio manager: Base Salary – Base salary is determined based on core job responsibilities, positions/levels and market factors. Base salary levels are reviewed annually, when there is a significant change in job responsibilities or position, or a significant change in market levels. Variable Compensation – In addition to a base salary, portfolio managers have a variable component of their compensation, which is based on a combination of individual and company performance and includes both qualitative and quantitative factors. The following non-exhaustive list of qualitative and quantitative factors is considered when determining total compensation for portfolio managers: • Performance measured over a variety of longer- and shorter-term periods, including 5-year, 4-year, 3-year, 2-year and 1-year dollar-weighted and account-weighted, pre-tax total and risk-adjusted investment performance as judged against the applicable benchmarks (which may include internal investment performance-related benchmarks) for each account managed by a portfolio manager (including the Fund) and relative to applicable industry peer groups and; • Amount and nature of assets managed by the portfolio manager. The variable compensation component of an employee’s compensation may include a deferred component. The deferred portion will generally be subject to vesting and may appreciate or depreciate based on the performance of PIMCO and/or its affiliates. PIMCO’s Long-Term Incentive Plan provides participants with deferred cash awards that appreciate or depreciate based on PIMCO’s operating earnings over a rolling three-year period. Portfolio managers who are Managing Directors of PIMCO receive compensation from a non-qualified profit sharing plan consisting of a portion of PIMCO’s net profits. Portfolio managers who are Managing Directors receive an amount determined by the Compensation Committee, based upon an individual’s overall contribution to the firm.
