HMOs are not available in all areas and the plan choices vary based on your zip code. The Benefits Connection enrollment website will indicate if an HMO is available in your area, and the website will display the monthly cost for each plan available to you. Typically, you need a referral to a specialist under the Medical HMO Plans. new monthly premium cost Chevron will currently continue to share the monthly cost of coverage the premium with you. Typically the monthly premium amounts for Medical HMO Plans are only available starting with the open enrollment preview period, but we re making this information available early to support your decisionmaking process this year.

Out-of-network services are not covered (except for certain emergency situations). That will not change. But in 2017, most HMOs will introduce a new annual deductible. The average annual deductible for most Medical HMO Plans is $300. However, some Medical HMO Plans may have a different deductible, and a few will continue to have no deductible at all.

See your Medical HMO Plan s Summary of Benefits and Coverage (SBC) for more information about your Medical HMO Plan s features or contact the HMO directly. Even if your current Medical HMO Plan will be available in 2017, that doesn t guarantee that it is still available to you. Each year, the HMOs review the ZIP codes and counties in which they have providers. An HMO may choose to discontinue coverage to residents of certain areas. Your HMO provider may have changed. Remember that HMOs require you to use doctors, pharmacies and hospitals that are part of their provider network. Contact your HMO directly to find out if your current provider continues to be in the network. If not, you will need to change providers or choose a new medical plan option to ensure that your medical services continue to be covered. Copayment and other changes in your current HMO coverage may apply because of state filings, compliance with the Health Care Reform law provisions, or to align them more closely with Chevron s standard benefit design. You ll be able to view more information about Medical HMO Plan changes, if any, in the 2017 Evidence of Coverage document available for each Medical HMO Plan. Contact the HMO directly to request a copy. Important reminder about your mental health and substance abuse coverage If you are enrolled in a Chevron Medical HMO Plan, you have the choice to use the mental health and substance abuse benefits provided by your Medical HMO Plan, or to use the benefits provided under the MHSA Plan administered by Beacon Health Options. However, you cannot make a claim to both your Medical HMO Plan and the MHSA Plan for the same service. If you are enrolled in a Chevron Medical HMO Plan and you choose to use your MHSA Plan benefit, remember you must use a Beacon network provider to receive benefits. Out-of-network provider services are covered for emergencies only. U.S. Pay and Benefit News 20

get your dental preventive care in 2017, save money on your 2018 dental HMO plan premium We know dental exams like many other preventive care exams are not exactly fun. But there s a reason they are covered by your plan: they are important to good health. The Dental HMO Plan already covers at least two preventive dental cleanings per year, one per six month period; that will continue in 2017. Covered preventive dental services are 100 percent paid by your plan, with no annual maximum, deductible or copayment when you use a network provider. If you are enrolled in the Chevron Dental HMO Plan, you re encouraged to take steps to protect your health and receive at least one preventive dental cleaning* between January 1 and December 31, 2017. If you do not participate in this preventive care measure in 2017, you will pay $120 more for your annual dental plan premium in 2018. It s still your choice to receive a cleaning or not, but if you choose to participate, you ll save money in 2018 and you ll be doing something good for your health. * For participants with dentures, receive at least one oral exam in lieu of a cleaning. Do I need to find a new dentist? With an HMO you must visit a provider in the HMO s network, otherwise your services aren t covered (except for certain emergency situations). If your provider is not in the network, you will need to change providers or choose a new dental plan option to ensure that your dental services continue to be covered.

A primary care dentist will be automatically assigned to you, but if you want to change dentists, be sure to do so before you schedule an appointment. (See Page 75.) new dental ID cards and enrollee ID You don t need an ID card to receive services, but a DeltaCare USA card for the Dental HMO Plan will be mailed to you prior to January 1. Just tell your dental office that you re covered by DeltaCare USA and provide your: Name Date of birth Employer Name Enrollee ID number (or social security number) If you have enrolled dependents, tell them to provide your details, not their own. What s my Enrollee ID? Your social security number can also be used to identify you, but we all want to avoid sharing that number whenever possible. Your Enrollee ID is a safer choice. DeltaCare will mail a letter to you prior to January 1 that contains your Enrollee ID and ID card, among other useful information. orthodontic treatment in progress The Dental HMO Plan is a health maintenance organization (HMO) dental plan option, so you must visit a provider in the HMO s network, otherwise your services aren t covered. If you or an enrolled dependent has started orthodontic treatment under the UCCI or Cigna Dental plan, you may be able to continue that coverage when you switch to the DeltaCare Dental HMO Plan in 2017. Through a provision called orthodontic treatment in progress, your DeltaCare plan allows you to continue treatment you started under your previous dental plan. You can visit the same orthodontist and have the same coverage and copayments as your previous plan. You pay the same amount that you would have paid under your previous coverage, as long as you remain eligible for coverage under your DeltaCare plan. If you started orthodontic treatment in 2016 (or earlier) under your previous UCCI or Cigna dental plan, and if banding has taken place, you are eligible for continuous orthodontic coverage under your DeltaCare USA Dental HMO Plan and may continue to visit the same orthodontist. If banding has not occurred, you are not eligible for continuous orthodontic coverage. In that case, orthodontic treatment must be provided by a DeltaCare network orthodontist in accordance with the copayments, limitations and exclusions defined in your DeltaCare USA Dental HMO Plan. September 2016 45

You must sign up between January 1 and January 31, 2017 to receive this continuous orthodontic coverage.

For service dates starting on or after January 1, 2017, Delta Dental Insurance Company will become the claims administrator and the DeltaCare USA network, copayment and fee schedules will apply. deltacare website and mobile app DeltaCare provides three ways for you to stay on top of your dental benefit: visit the website from your computer, access the mobile-optimized website via your smartphone, or download and use the free app. No matter which source you choose you ll be able to: Find a dentist (note that you don t have to login to search for a network dentist).

Smokeless tobacco (such as snuff or chewing tobacco). E-cigarettes do not contain tobacco, so at this time e-cigarettes are not included in the tobacco use definition.

Medical HMO Medical HMO Plans Chevron offers several health maintenance organization (HMO) medical plan options that include medical coverage, prescription drug coverage and basic vision coverage. With an HMO you must visit a provider in the HMO s network, otherwise your benefits aren t covered (except for certain emergency situations). HMOs are not available in all areas and the plan choices vary based on your zip code. The Benefits Connection enrollment website will indicate if an HMO is available in your area and the website will display the monthly cost for each plan available to you. Typically, you need a referral to a specialist under the Medical HMO Plans. The Medical HMO Plans offer comprehensive coverage for the major medical services you d expect, including office visits, emergency services, hospital care, lab services, outpatient care, pregnancy and newborn care and rehabilitative services. Medical Services, Prescription Drugs, Basic Vision: Provided by the HMO Preventive Care All Medical HMO Plans include 100 percent coverage with no deductible for certain preventive care services as specified by the Affordable Care Act when you see a network provider. Additional preventive screenings and services may also be covered, depending on factors like your age and gender. Deductibles There are generally no deductibles in the Medical HMO Plans, but coinsurance or copayments generally apply for all covered services and supplies. Health Care Spending Account (HCSA) You are eligible to participate in the Health Care Spending Account (HCSA), a flexible spending account. The funds you contribute to this account do not roll over from year to year. Learn more about the HCSA on hr2.chevron.com. Choose Open Enrollment. Health Savings Account (HSA) You cannot participate in a health savings account when enrolled in a Medical HMO Plan. However, you can use funds from an existing HSA to pay for qualified medical expenses while participating in a Medical HMO Plan. Mental Health and Substance Abuse (MHSA) Plan If you are enrolled in a Chevron Medical HMO Plan, you have the choice to use the mental health and substance abuse benefits provided by your HMO Plan, or to use the benefits provided under the MHSA Plan administered by ValueOptions, a Beacon Health Company. However, you cannot make a claim to both your HMO Plan and ValueOptions for the same service. If you are enrolled in a Chevron Medical HMO Plan and you choose to use your ValueOptions MHSA benefit, remember you must use a ValueOptions network provider to receive benefits. Out-ofnetwork provider services are covered for emergencies only. U.S. Pay and Benefits News 29

Medical HMO Plan Reminders An HMO option may be available to you in your area. The Benefits Connection website will list the HMOs available to you next year (if any). Your provider or other plan features, like monthly premiums, copayments or prescription drug coverage could change. See your plan s Summary of Benefits and Coverage (SBC) for more information about your plan s features or contact the HMO directly (See Page 10). Even if your current HMO will be available in 2016, that doesn t guarantee that it is still available to you. Each year, the HMOs review the ZIP codes and counties in which they have providers. An HMO may choose to discontinue coverage to residents of certain areas. Your HMO provider may have changed. Remember that HMOs require you to use doctors, dentists and hospitals that are part of their provider network. Contact your medical or dental HMO directly to find out if your current providers continue to be in the network. If they are not, you will need to change providers or choose a new plan to ensure that your medical and dental services continue to be covered. Copayment and other changes in your current HMO coverage may apply because of state filings, compliance with the Health Care Reform law provisions, or to make them more closely align with Chevron s standard benefit design.

How to Certify Your Tobacco Use Status All employees (including employees on a leave of absence who are not receiving coverage through COBRA) are required to certify their tobacco use status during open enrollment, October 20 through October 31, 2014. During this year s open enrollment period, October 20 through October 31, 2014, all U.S.-payroll employees who participate in Chevron medical or supplemental life insurance coverage will be required to certify their tobacco use status. If you fail to follow the steps to certify your tobacco use status during open enrollment, you ll be charged the higher monthly rates for medical and supplemental life insurance coverage for all of 2015, whether or not you use tobacco. You will not lose your coverage in these plans if you fail to certify, but you will pay the higher rate. If you miss the deadline, you cannot change your tobacco use status until next year s open enrollment for 2016 benefits. Note: COBRA participants are not required to certify their tobacco use status at this time. Tobacco use can affect your health. And your health is important to your quality of life, your family, your career, and the health of our business. That s why Chevron announced an important change to medical and supplemental life insurance coverage earlier this year. Starting January 1, 2015, Chevron will establish a tobacco surcharge for medical and supplemental life insurance coverage. This means there will be different monthly rates for this coverage for tobacco and non-tobacco users. It matters to Chevron that you re in good health at work and at home. That s why we offer a variety of wellness programs and resources to encourage and support better health. We hope our employees tobacco and nontobacco users alike take advantage of these opportunities, whether it s to try to stop using tobacco, participate in exercise programs, or take steps to protect your heart. How to Certify You can certify your tobacco use status by calling the HR Service Center (see Page 6) or by going online to Benefits Connection, the same website you use to make open enrollment elections. If you access Benefits Connection, from the Chevron network, you can use the automatic sign-in feature and you don t need a PIN. But if you need to certify your tobacco use status from outside the Chevron network or by phone, you ll need your PIN. A PIN reminder was mailed to you in September, but if you still don t know your PIN or can t find it, you can request a new one online or by calling the HR Service Center. It can take up to two weeks to receive your PIN in the mail, so take action right away if you need it. Go to hr2.chevron.com and click Open Enrollment, then the Certify Tobacco Status button. Login to Benefits Connection. Choose the Enroll Today button, then the Make Your Elections Now button. From the Make Coverage Elections screen, look for Tobacco Certification and choose Change. After you certify your tobacco use status, your Make Coverage Elections screen will be updated according to your certification choice. 8 Open Enrollment October 2014

Your Certification Choices When you certify your tobacco use status, you ll be asked to choose from the status options listed below. Here s what those choices are and what they mean. Tobacco User Tobacco use is a personal choice. It s not our goal to intrude on your personal life and take away that choice. That s why if you currently use tobacco, you can continue using it. If you re a tobacco user and don t intend to stop using tobacco, you ll pay $25 more each month in 2015 for medical coverage than employees who are not tobacco users. If you participate in Chevron s Supplemental Life Insurance Plan, you ll also pay 20 percent more each month in 2015 for that coverage. The higher rates will take effect on January 1, 2015. Your benefit plan and the level of coverage you receive will be the same as non-tobacco users, the only difference will be that you pay a higher monthly cost for your coverage. Tobacco User, But Will Try to Quit If you commit to try to stop using tobacco during 2015, we have support resources to help you, and you ll pay the lower monthly rate too. Go to hr2.chevron.com for resources. Not a Tobacco User If you don t use tobacco you will not be subject to the higher medical and supplemental life insurance rates in 2015 as long as you certify your tobacco use status during open enrollment, October 20 through October 31. If you fail to meet this deadline, you ll be charged the higher monthly rates for medical and supplemental life insurance coverage for all of 2015. Decline to Disclose You can choose to decline to disclose your tobacco use status, but you ll be charged the higher monthly rates for medical and supplemental life insurance coverage for all of 2015, whether or not you use tobacco. What s considered tobacco use? You ll be asked to indicate your tobacco use status only. You don t have to certify the tobacco use status of your spouse or domestic partner and other dependents for 2015. Any use, regardless of frequency or location, is considered use. This includes daily, occasional or social use. It also includes if it s used only at your home. Use of the following since July 1, 2014, will be considered tobacco use: Tobacco (such as cigarette, pipe, cigar). Smokeless tobacco (such as snuff or chewing tobacco).
