VESTINGYou always own 100% of the value of your contributions or any money you rollover to the Plan. You will vest (gain ownership) in the Company match in accordance with the following schedule:

YEARS OF SERVICE VESTING PERCENTAGE

Less than 1 year 0%

1 20%

2 40%

3 60%

4 80%

5+ 100%

EMPLOYER CONTRIBUTION If you were hired on or after March 1, 2011, CMC will also make an Employer Contribution of 1% of your eligible earnings per pay period, regardless of your own contribution rate. You are immediately vested in Employer Contributions.

ROLLOVER CONTRIBUTIONSIf you have an existing retirement plan account with a prior employer or a rollover IRA, you may transfer or roll over all or some of that account into your account. By doing so, you combine your retirement savings in one place and your account can continue to grow.

The TAMCO Savings Plan for Rancho Cucamonga United Steelworkers Employees (USW Plan) offers you a Company match and variety of investment options. Plus, the Plan has some additional features designed to help you grow your savings a little more each year. This guide provides a brief overview of how the Plan works, what you need to do and where to go to learn more.

PLAN FACTS – YOU’RE IN! As a full-time employee, you are eligible to join the USW Plan upon your date of hire.

YOUR CONTRIBUTIONSWhen you make your elections, you can save from 1% to 75% of your pay, up to IRS limits. Your contributions are pre-tax contributions, which are deducted from your pay before federal income taxes are withheld. You pay taxes on these contributions and earnings when you withdraw money from the Plan.

If you’ll be age 50 or older during the calendar year, additional catch-up contributions are also allowed, up to IRS limits.

GET PAID TO SAVE – COMPANY MATCHMake sure you’re not leaving any money on the table – contribute at least 4% to get the full Company match!

• If you were hired before March 1, 2011, CMC will contribute 25¢ for every $1 you save up to the first 4% of your pay.

• If you were hired on or after March 1, 2011, CMC will contribute 50¢ for every $1 you save up to the first 4% of your pay.

CMC is invested in your future – and we want you to be, too!

INVESTMENT CHOICES The Plan offers two approaches to investing:

• Vanguard Target Date Funds. Target Date funds are designed to take the confusion out of investing. They provide diversified investment mixes based on expected retirement dates and automatically shift to a more conservative blend as you near your target retirement date.

• Custom Investment Portfolio. You design your own asset allocation. You may choose to invest in any combination of the Plan’s investment options, which represent a broad range of risk and return characteristics within various asset classes. To view the full investment lineup, log on to MillimanBenefits.com.

Your account will be invested in the Vanguard Target Retirement Fund that most closely aligns with your normal retirement date (defined in the Plan as age 65). It will stay invested in that fund until you elect an alternate investment. You can make or change your investment elections at any time on MillimanBenefits.com.

LOANSYou may borrow from your rollover and pre-tax accounts. The minimum loan amount is $1,000 and only one outstanding loan at a time is allowed. Use the loan modeling tool on MillimanBenefits.com to see what the loan payment would be if you borrow different amounts of money for different periods of time. Based on that information, you can set the loan amount and repayment schedule that fit your needs.

Caution! Keep in mind that any money you take out of your account as a loan won’t be able to help you earn toward your retirement. If you really need a loan, be sure you’re only taking as much as you need and repay it as soon as you are able.

IN-SERVICE WITHDRAWALSYou may take an in-service withdrawal for several reasons:

• Rollover account. You may withdraw money you rolled into this Plan at any time.

• Age 59½. Once you reach age 59 ½, you may request a withdrawal for any reason from any account in which you are fully vested.

• Financial hardship. You may apply for a financial hardship withdrawal from your own pre-tax contributions.

Details are provided in the Summary Plan Description or on MillimanBenefits.com.

DISTRIBUTIONSIf you leave employment with CMC and your vested account balance is $1,000 or less, your vested account balance will be payable as a single lump sum payment. If your vested account balance is greater than $1,000 but $5,000 or less, and you do not elect otherwise, your vested account balance will roll over automatically to an Individual Retirement Account (IRA). You have the option of transferring your account in cash to an IRA or another eligible retirement plan to continue deferring taxes. You may leave your money in the Plan if your balance is $5,000 or more (excluding rollover contributions). You should consider your distribution options carefully to avoid penalties and taxes.
