Michael Plage is co-manager of Fidelity Puritan Fund and receives compensation for managing the bond investments of the fund. As of July 31, 2015, portfolio manager compensation generally consists of a fixed base salary determined periodically (typically annually), a bonus, in certain cases, participation in several types of equity-based compensation plans, and, if applicable, relocation plan benefits.

Each co-manager's base salary is determined by level of responsibility and tenure at FMR or its affiliates.

The primary components of Mr. O'Neil's bonus are based on (i) the pre-tax investment performance of the portfolio manager's fund(s) and account(s) measured against a benchmark index assigned to each fund or account, and (ii) the investment performance of other FMR taxable bond funds and accounts. The pre-tax investment performance of the portfolio manager's fund(s) and account(s) is weighted according to his tenure on those fund(s) and account(s) and the average asset size of those fund(s) and account(s) over his tenure. Each component is calculated separately over the portfolio manager's tenure on those fund(s) and account(s) over a measurement period that initially is contemporaneous with his tenure, but that eventually encompasses rolling periods of up to three years for the comparison to a benchmark index. A smaller, subjective component of the portfolio manager's bonus is based on the portfolio manager's overall contribution to management of FMR. The portion of Mr. O'Neil's bonus that is linked to the investment performance of Fidelity Balanced Fund is based on the pre-tax investment performance of the bond investments of the fund measured against the Barclays U.S. Aggregate Bond Index. The portion of the portfolio manager's bonus that is linked to the investment performance of Fidelity Puritan Fund is based on the pre-tax investment performance of the bond investments of the fund measured against the Barclays U.S. Aggregate Bond Index.

Each co-manager also is compensated under equity-based compensation plans linked to increases or decreases in the net asset value of the stock of FMR LLC, FMR's parent company. FMR LLC is a diverse financial services company engaged in various activities that include fund management, brokerage, retirement, and employer administrative services. If requested to relocate their primary residence, portfolio managers also may be eligible to receive benefits, such as home sale assistance and payment of certain moving expenses, under relocation plans for most full-time employees of FMR LLC and its affiliates.
