About these balances

Latest available filing per company, not a reconstructed current portfolio. Matching sequences show the last reported balance with all source rows expandable; grouping alone does not establish account ownership. Do not add unresolved positions together. Filings may omit unchanged positions, and amendments may correct only part of an older disclosure. Jointly reported shares are not necessarily this owner's personal holdings.

F2 · derivative.expiration_date: On the third anniversary of the grant date, Performance-Based Restricted Stock Units ("PSUs") vest based on achievement of total shareholder return ("TSR") performance relative to the S&P Health Services Industry Index over a three-year period beginning in 2020 and ending in 2022. Payout for vested PSUs ranges from 0% to 200% of the indicated number of shares, based on the Company's TSR percentile ranking compared to the TSR of the companies included in the selected market index. TSR is measured generally as the increase or decrease in the market value of the Company common stock with a deemed reinvestment of any dividends. If a participant terminates employment prior to the third anniversary of the grant date, the PSUs generally will be forfeited. PSUs have no voting rights and are generally non-transferable. The indicated number of PSUs assumes 100% vesting, and the actual number of shares issued in settlement of the PSUs may be greater or less than the indicated number.

F3 · derivative.expiration_date: (Continuation of Footnote 3) - Since the payout for PSUs can range from 0% to 200%, the maximum number of shares that could vest and be issued could be double the indicated number.
