Open Enrollment is your once-a-year opportunity to make sure your benefits continue to fit your needs. Unless you experience a qualifying life event, this is the only time you can make plan changes, add or drop coverage for dependents, or enroll in a new plan.

Enroll November 1–15, 2023

Take the time to explore all the benefits available to you in 2024. Then, choose the ones that will meet your needs.

If you don’t enroll, you will have the same medical and vision plans you had in 2023, and you will not have a Health Care or Dependent Day Care Flexible Spending Account (FSA). If you are currently enrolled in the Delta Dental Preventive Plan, you must enroll in the new Base Plan or Premium Plan to have dental coverage in 2024.

2024 enrollment is closed

You cannot change your benefits for 2024 unless you have a qualifying life event.

Who’s eligible for benefits

If you’re a full-time or part-time regular-status Lam or Silfex employee who works 20 or more hours per week, you’re eligible for Lam benefits. Your spouse or domestic partner and children may also be eligible. No other family members, including parents, are eligible, even if they live with you.

Learn how

If you take no action during Open Enrollment

  • You and your enrolled dependents will be enrolled in the medical, dental, and vision plans that are most similar to your 2023 plans.
    • Exception: If you’re enrolled in the Delta Dental Preventive Plan (which is being discontinued), you will have no dental coverage in 2024 if you do not elect another plan.
  • If you waived health care coverage in 2023, you will continue to have no Lam health care coverage in 2024.
  • You will not be able to contribute to a Health Care FSA or Dependent Day Care FSA in 2024.
  • Your 2023 HSA employee contribution amount election will roll over to 2024. You’ll need to select a new contribution amount if you want to hit the new, higher HSA maximum for 2024.
  • You will be enrolled automatically in the applicable short-term disability plan (VDI for California employees and STD for all others). 

No change to vision and dental contributions

For the third year in a row, we are not increasing the employee contributions for the vision plans or the two dental plans we’re offering in 2024.

Tips for using the enrollment site

  • The site will display your benefit options with a button that says View or Change Plan (if you have an election carrying over from 2023) or Shop Plans (if you do not yet have an election for 2024). Click the button to see your benefit plan choices.
  • When you’ve made a new benefit election, click the Update Cart button.
  • If you want to decline a plan, click the blue text below the Update Cart button that says Decline <type of coverage>.
  • Be sure to add your dependents to each plan as you select your benefits. Simply adding dependents to PlanSource in step 2 does not enroll them in benefits. To ensure each family member is enrolled, review Family Covered under each benefit.
  • You must click Checkout at the bottom of the page to save your benefit elections and complete your enrollment.
