Equity-Based Compensation

We record compensation expense for equity-based awards, such as restricted stock, deferred stock and performance awards, based on the closing price of our common stock on the date of grant, adjusted if appropriate based on the award’s eligibility to receive dividends. The fair value of stock appreciation rights are determined using the Black-Scholes valuation model.

Compensation expense related to equity-based awards with service-only conditions and terms that provide for a graded vesting schedule is recognized on a straight-line basis over the required service period for the entire award. Compensation expense related to equity-based awards with performance conditions and terms that provide for a graded vesting schedule is recognized over the requisite service period for each separately vesting tranche of the award, and is based on the probable outcome of the performance conditions at each reporting date. Compensation expense is adjusted for assumptions with respect to the estimated amount of awards that will be forfeited prior to vesting, and for employees who have met certain retirement eligibility criteria. Compensation expense for common stock awards granted to employees meeting early retirement eligibility criteria is fully expensed on the grant date.

Dividend equivalents for certain equity-based awards are paid on stock units on a current basis prior to vesting and distribution.

The 2017 Stock Incentive Plan, or 2017 Plan, was approved by shareholders in May 2017 for issuance of stock and stock based awards. Awards may be made under the 2017 Plan for (i) up to 8.3 million shares of common stock plus (ii) up to an additional 28.5 million shares that were available to be issued under the 2006 Equity Incentive Plan, or 2006 Plan, or may become available for issuance under the 2006 Plan due to expiration, termination, cancellation, forfeiture or repurchase of awards granted under the 2006 Plan. As of December 31, 2017, a total of 17.9 million shares from the 2006 Plan have been added to and may be issued from the 2017 Plan. As of December 31, 2017, a cumulative total of 0.4 million shares had been awarded under the 2017 Plan and 68.9 million had been awarded under the 2006 Plan. As of December 31, 2016 and 2015, we had cumulative totals of 65.7 million shares and 60.9 million shares, respectively, awarded under the 2006 Plan. The 2017 Plan allows for shares withheld in payment of the exercise price of an award or in satisfaction of tax withholding requirements, shares forfeited due to employee termination, shares expired under options awards, or shares not delivered when performance conditions have not been met, to be added back to the pool of shares available for issuance under the 2017 Plan. From inception to December 31, 2017, fewer than 1 million shares had been awarded under the 2017 Plan but not delivered, and have become available for reissue. As of December 31, 2017, a total of 25.9 million shares were available for future issuance under the 2017 Plan.

The exercise price of non-qualified and incentive stock options and stock appreciation rights may not be less than the fair value of such shares on the date of grant. Stock options and stock appreciation rights granted under the 1997 Equity Incentive Plan, or 1997 Plan, and the 2006 Plan, collectively the Plans, generally vest over four years and expire no later than ten years from the date of grant. No common stock options or stock appreciation rights have been granted since 2009. For restricted stock awards granted under the Plans, common stock is issued at the time of grant and recipients have dividend and voting rights. In general, these grants vest over three to four years. As of December 31, 2017 there are no outstanding stock options or restricted stock awards.

For deferred stock awards granted under the Plans, no common stock is issued at the time of grant and the award does not possess dividend and voting rights. Generally, these grants vest over one to four years. Performance awards granted are earned over a performance period based on the achievement of defined goals, generally over three years. Payment for performance awards is made in shares of our common stock equal to its fair market value per share, based on the performance of certain financial ratios, after the conclusion of each performance period.

Beginning with 2012, malus-based forfeiture provisions were included in deferred stock awards granted to employees identified as “material risk-takers,” as defined by management. These malus-based forfeiture provisions provide for the reduction or cancellation of unvested deferred compensation, such as deferred stock awards and performance based awards, if it is determined that a material risk-taker made risk-based decisions that exposed State Street to inappropriate risks that resulted in a material unexpected loss at the business-unit, line-of-business or corporate level. In addition, awards granted to certain of our senior executives, as well as awards granted to individuals in certain jurisdictions, may be subject to recoupment after vesting (if applicable) and delivery to the individual in specified circumstances generally relating to fraud or willful misconduct by the individual that results in material harm to us or a material financial restatement.

Compensation expense related to stock options, stock appreciation rights, restricted stock awards, deferred stock awards and performance awards, which we record as a component of compensation and employee benefits expense in our consolidated statement of income, was $243 million, $268 million and $319 million for the years ended December 31, 2017, 2016 and 2015, respectively. Such expense for 2017, 2016 and 2015 excluded $15 million, $9 million and $10 million, respectively, associated with acceleration of expense in connection with targeted staff reductions. This expense was included in the severance-related portion of the associated restructuring charges recorded in each respective year.

We utilize either treasury shares or authorized but unissued shares to satisfy the issuance of common stock under our equity incentive plans. We do not have a specific policy concerning purchases of our common stock to satisfy stock issuances, including exercises of stock options. We have a general policy concerning purchases of our common stock to meet issuances under our employee benefit plans, including option exercises and other corporate purposes. Various factors determine the amount and timing of our purchases of our common stock, including regulatory reviews and approvals or non-objections, our regulatory capital requirements, the number of shares we expect to issue under employee benefit plans, market conditions (including the trading price of our common stock), and legal considerations. These factors can change at any time, and the number of shares of common stock we will purchase or when we will purchase them cannot be assured. See Note 15 for further information on our common stock purchase program.
