401(k) Plan

• Save on a pretax or Roth basis. Roth contributions are deducted from your paycheck after taxes are withheld.
• Change or stop your contributions at any time.
• You have the flexibility to select from investment options that range from more conservative to more aggressive, making it easy for you to develop a well-diversified investment portfolio.
• You can roll over eligible savings from a previous employer into this plan. You can also take your plan vested account balance with you if you leave the company.
• You can designate your beneficiaries, receive instant online confirmation, and check your beneficiary information virtually at any time.

You can contribute via convenient pretax or after-tax (Roth) payroll deductions, up to the IRS contribution limit each year. Here are the annual contribution limits for 2025:

• Under age 50: $23,500
• Ages 50–59 (standard catch-up): $31,000, including an additional $7,500 standard catch-up contribution
• Ages 60–63 (super catch-up): $34,750, including the standard contribution, the catch-up contribution and an additional super catch-up contribution, which can help if you feel behind on your retirement savings or wish to invest more as retirement nears (the additional funds will have more time to grow in your 401(k), allowing you to benefit from compound interest)
• Ages 64 and older (standard catch-up): $31,000, including an additional $7,500 standard catch-up contribution

CSL’s 401(k) plan allows you to save for your future by helping you boost your retirement savings through company-provided contributions.

All full-time and part-time employees are eligible to join the 401(k) plan from their date of hire. CSL matches 100% on the first 6% of contributions you make to your CSL retirement account. At its discretion, the company may also make an annual non-elective contribution to your account after one year of service, provided you meet these eligibility criteria:

• You're 21 or older on the last day of the plan year
• You have at least 12 continuous months of service during the plan year
• You've completed at least 975 hours of service during the plan year
• You're employed with CSL on the last day of the plan year

Here’s the annual non-elective contribution you’re eligible for, based on your age and years of service:

Here’s how it adds up:

6% company match

+ 2%, 4% or 6% annual non-elective employer contribution

= 8%–12% TOTAL in company money put into your 401(k) account each year!

You're always 100% vested in your own contributions and any applicable employer match, and you become 100% vested in the annual non-elective contribution after three years of service.
