USS 401(K) PLAN FOR USW-REPRESENTED EMPLOYEES Estimated Average Employee Contribution Amount

• Participants may contribute from 1 percent to 40 percent (in whole percentages) of regular compensation as pre-tax contributions and/or Roth 401(k) contributions (18 percent if the participant is a highly compensated employee) and, in 10 percent increments, up to 100 percent of bonus type payments, as defined by the Plan.
• For one bargaining unit, effective in May 2019, the Plan has an auto-enrollment feature where eligible employees are automatically enrolled in the Plan at a pre-tax contribution percentage of 3 percent of regular compensation per pay period, unless they select a different pre-tax contribution percentage amount or make an affirmative election not to contribute to the Plan.
• Additionally, the Plan has an auto-escalation feature for this bargaining unit where the initial 3 percent pre-tax contribution percentage will automatically increase by 1 percent on the enrollment anniversary date each year until the contribution percentage reaches 6 percent.
• The Plan has an auto-escalation feature where participants can elect to have their pre-tax contribution percentage (or Roth 401(k) contribution percentage if no pre-tax contributions are elected) increased annually by 1 percent to 10 percent on a date chosen by the participant.

• Plan participants at certain bargaining units participate in a non-contributory defined contribution Retirement Account under the Plan (in amounts provided in the applicable bargaining agreement) with a vesting requirement of two years of service (subject to exceptions).
• Plan participants hired on or after January 1, 2016, including certain rehired employees at certain bargaining units, participate in a non-contributory defined contribution Retiree Health Care Account under the Plan (in amounts provided for in the applicable bargaining agreement).

• Employee savings in increments of 1 percent may be invested among the investment options offered under the Plan.
• All investments are participant directed.
• Pre-tax savings and earnings thereon and Roth 401(k) savings and earnings thereon are available only for withdrawal at termination of employment or age 59½, except under certain financial hardship conditions.
• Rollover withdrawals are permitted at any time.
• Vested company contributions and earnings are available for withdrawal upon vesting.
• A participant who terminates employment for any reason, and who, on the effective date of termination, had two or more years continuous service, is entitled to receive his or her entire account balance, including (for certain bargaining units) all Retirement Account contributions.
• A participant who terminates employment for any reason with less than two years continuous service will forfeit nonvested Retirement Account contributions (if applicable to the bargaining unit) unless termination is by reason of permanent layoff, total and permanent disability, or death.
