Explanation of Responses:

( 1 )Represents the number of shares earned in connection with performance shares previously granted on 1/12/2016, based on achievement of certain targets in the period ended 10/31/2018. Inadvertently, these performance shares were not reported at the time they were earned (12/21/2018), but were reported on a subsequent Form 4 disclosing their vesting and payout on 1/12/2019. As a result, none of these performance shares are being added to the reporting person's beneficial ownership total in this Form 4 to avoid double-counting. ( 2 )Represents the number of shares earned in connection with TSR performance shares previously granted on 9/12/2016, based on TSR performance in the 3-year period ended 10/31/2018 as compared to the S&P SmallCap 600 Index. Such TSR performance shares vested on 9/12/2019. Inadvertently, these TSR performance shares were not reported at the time they were earned (12/21/2018). ( 3 )Dividend equivalent rights (DERs) accrued on earned TSR-performance shares under the 2006 Equity Incentive Plan. Each DER is the economic equivalent of one share of ABM common stock. ( 4 )Includes 24,212 unvested RSUs and DERs relating to the unvested RSUs, adjusted to reflect the cumulative effect of fractional shares.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
