BTF V3 TRANSITION The National IAM Benefit Trust Fund (the “BTF”) will begin transitioning to V3locity or “V3”, a benefits adminis - tration system designed to enhance the efficiency, productivity, and func - tionality of Fund administration, in early 2023. Our new V3 Employer Self-Service portal (“ESS”) will offer electronic billing and contribution remittance, real-time enrollment, and eligibility reporting, as well as other features to help streamline adminis - trative duties. Mid-to-late 2023, the Fund will also introduce its first V3 Participant Self-Service portal (“PSS”) giving employees access to up-to- date information on their covered benefits, and eligible dependents, as well as important Plan documents and notices. Beginning in 2023, all BTF contribut - ing employers will be required to use ESS to complete their enrollment and eligibility reporting. Once ESS goes live, the Fund will no longer accept paper enrollments or email requests. Employers should ensure they do not miss any critical BTF instructions or information by confirming or updat - ing their key contact(s) for receiving V3-related communications by email - ing the Employer Contact Change Form to fundrep@iambtf.org . Their key contacts must include anyone who is responsible for submitting en - rollment or eligibility files to the Fund. We appreciate your patience and continued engagement during this transition. 2 Latest News and Highlights Andy Chen COMPLIANCE M A I L I NGS The following compliance mail - ings and regulatory notices were mailed from the IAM National Benefit Funds Office in 2022: › 2021 401(k) and BTF SAR & HIPAA Notice of Privacy Practices › 2022 401(k) QDIA/ACA/Fee Disclosure › 2022 Annual Federal Tax Withholding Notice › 2022 NPF Social Security Administration Letters › 2022 NPF 104(d) Notice/ Multiemployer Summary Report › 2022 NPF Annual Benefit Statement › 2022 NPF Summary of Material Modifications › 2022 Annual Funding Notice › 2022 BTF MER, NCC and WHCRA › 2023 BTF Summary of Benefits and Coverage (A, A+, B, C, D2) › 2023 NPF Summary Plan Description If you did not receive a specific compliance mailing, please contact the appropriate IAM National Pension Fund/401(k) Plan Customer Service at 1-800-424- 9608 or the National IAM Benefit Trust Fund Customer Service at 1-800-457-3481.

IAM GRAND LODGE CONVENTION IN REVIEW October 2-7, 2022, the IAM National Benefit Funds Office participated in the 40th IAM Grand Lodge Conven - tion in Las Vegas, NV. Under the theme “IAM Standing Strong,” the Convention was the first major in-person meeting held by the IAM Grand Lodge since the pandemic. In one of the largest booths at the Convention, the Benefit Funds Office offered Fund education on floor- to-ceiling digital monitors while IAM members played Vegas-style games or took advantage of complimentary wellness massages. Our Education representatives met one-on-one with participants to answer questions about the benefits offered by each of the Funds and connected with the people we serve everyday. If you missed us in Vegas, be sure to catch the Benefit Funds Office booth at the 41st IAM Grand Lodge Convention in New York City in 2024! 3 3 5 6 4 2 1 Photos Left to Right: 1) The IAM Executive Council including IAM National Benefit Funds Office (IAMBFO) Union Trustees Dora Cervantes, Rickey Wallace, Steve Galloway and Brian Bryant posing on the Convention stage. 2) Entrance into the IAMBFO booth. 3) IAM Delegate playing Plinko game for special IAMBFO prize or grand prize entry. 4) Education team members, Elo Rosales and Cori Horowitz, speaking to IAM members. 5) IAMBFO Executive Leadership and Education Team left to right: Ned Johnson (Manager), Wendy Frye (Chief of Staff), Fred Ross, Sunni Isaac, Parris Celestine, Ryk Tierney (Executive Director), Elo Rosales, Cori Horowitz, Brittany Plummer and Damien Anderson. 6) IAM Delegate sporting his healthy prize from participating in the Plinko game.

If you are a Benefit Recipient of the IAM National Pension Fund (the “Fund”), you were given the opportunity to choose whether you want federal in - come tax withheld from your pension payments when you began receiving them. In accordance with the Tax Eq - uity and Fiscal Responsibility Act of 1982 (“TEFRA”), the IAM National Ben - efit Funds Office (the “Benefit Funds Office”) issues this annual notice to remind you that you may change your federal income tax withholding elec - tions at any time. If you do not wish to make any changes to your current fed - eral income tax withholding elections, no action is required. Please read the following informa - tion carefully and contact the Bene - fit Funds Office at 1-800-424-9608, Monday through Friday, 9:00 a.m. to 7:00 p.m. Eastern Time, if you have any questions about the information contained in this notice or need as - sistance completing your IRS Form W-4P (Withholding Certificate for Pe - riodic Pension or Annuity Payments) to update your federal income tax withholding elections. It is important to note the amount of the 2023 fed - eral income tax being withheld from your payments may change because the withholding tables have changed. PLEASE NOTE: The IRS has released a revised Form W-4P and a new Form W-4R (Withholding Certificate for Non - periodic Payments and Eligible Roll - over Distributions). Beginning January 1, 2023, you must use these new and revised forms to update your federal tax withholding elections with the Ben - efit Funds Office. Benefit Recipients retiring on or after January 1, 2023, should use the revised IRS Form W-4P. Your current federal income tax with - holding elections will remain in ef - fect until you submit a new IRS Form W-4P with the Benefit Funds Office. You may log on to our online portal at https://participant.iambfo.org/log - in/ to update your federal income tax withholding elections or download the IRS Form W-4P at https://www. iamnpf.org/participants/forms . Once you make a change to your federal in - come tax withholding, your elections will become effective on the first day of the month that is at least 30 days after we receive your form. Tax withholding on your benefit pay - ments is one way for you to pay a por - tion of your income tax. If not enough tax is being withheld from your total taxable income for the year, you may have to pay estimated taxes during the year or a tax penalty at the end of the year. Of course, whether or not you have to pay federal income tax depends on the total amount of your taxable income, not just on your ben - efit payments from the Fund. Remem - ber, for many people, Social Security benefits are not taxable. Your decision on withholding is an important one. If you need addition - al assistance estimating your tax, you should consult with a tax advisor or the IRS. The Benefit Funds Office is unable to assist you with computing your estimated federal income tax. Benefit Recipient Checkup: Review Your Federal Income Tax Withholding Elections 5 NEW SUMMARY PLAN DESCRIPTION IS COMING The Board of Trustees are pleased to present you with the 2023 Summary Plan Description (SPD) summarizing the IAM National Pension Fund’s Plan document. This SPD incorporates all amend- ments to the Plan through October 31, 2022, including the amendments made under the Rehabilitation Plan that the Board adopted in 2019 to improve the Plan’s funding status for the long- term benefit of participants and beneficiaries. This SPD generally applies to par - ticipants who apply for benefits on or after January 1, 2023. Par - ticipants who apply for benefits before that date should refer to the 2017 SPD (and any summa - ries of material modification to the 2017 SPD). We hope this summary will be of assistance to you and your family in understanding the Plan. We believe that this SPD accu - rately reflects the Fund. Please re - member, though, that the text of the Plan itself, as interpreted by the Board of Trustees, represents the final authority in all cases. 2 0 2 3 SUMMARY PLAN DESCRIPTION 2 0 2 3 SUMMARY PLAN DESCRIPTION COMING SOON

You are protected from balance bill - ing for: EMERGENCY SERVICES If you have an emergency medical condition and get emergency services from an out-of-network provider or fa - cility, the most the provider or facility may bill you is your plan’s in-network costsharing amount (such as copay - ments and coinsurance). You can’t be balance billed for these emergency services. CERTAIN SERVICES AT AN IN-NETWORK HOSPITAL OR AMBULATORY SURGICAL CENTER When you get services from an in-net - work hospital or ambulatory surgical center, certain providers there may be out-of-network.

This applies to emergen - cy medicine, anesthesia, pathology, radiology, laboratory, neonatology, assistant surgeon, hos - pitalist, or intensivist ser - vices. These providers can’t balance bill you and may not ask you to give up your protections not to be balance billed.

THE THREE MOST COMMON TYPES OF DIABETES: TYPE 1, TYPE 2 AND GESTATIONAL DIABETES. 2 TYPE 1 DIABETES Develops most often in young people, but it can also develop in adults. With type 1 diabetes, the body’s immune system has attacked and destroyed the cells that make insulin, thus decreasing the body’s insulin production. TYPE 2 DIABETES If you have type 2 diabetes, your body does not make or use insulin well. It develops most often in middle-aged and older people, but it can also affect people at any age – even children. People who are overweight and have a family history of diabetes are also more likely to develop type 2 diabetes. GESTATIONAL DIABETES Can develop when a woman is pregnant. Pregnant women make hormones that can lead to insulin resistance. All women have insulin resistance late in their pregnancy, but some experience it earlier on. If the pancreas doesn’t make enough insulin during pregnancy, a woman develops gestational diabetes. While gestational diabetes typically goes away after the baby is born, a woman who has had gestational diabetes is more likely to develop type 2 diabetes later in life. Talk with your doctor, who can make the appropriate recommendations based on your health history. Have questions or concerns about your diabetes risk?

WHAT ARE THE SIGNS AND SYMPTOMS? 4 Some people with diabetes don’t have any signs or symptoms at all, so it’s important to see your doctor and get your blood work. If you do experience symptoms, here are some of the most common. 3. Reach and maintain a healthy weight Staying at a healthy weight lowers your risk of back pain. 2 It can help reduce the stress and strain on your back. 4. Practice good posture when seated, standing and sleeping 2 › Good posture can help prevent back pain. › Try not to slouch when standing and sitting. › Sit up straight with your back against the back of your chair and your feet flat on the floor. If possible, keep your knees slightly higher than your hips. › Stand tall with your head up and shoulders back. › If you can, switch between standing and sitting so you aren’t in the same position for too long. › If you’re a side sleeper, place a pillow between your knees. 3 › If you sleep on your back, place a pillow under your knees. 3 5. Avoid heavy lifting or learn good form to protect your back 2 › Lift things with your legs, not your back. › Keep your back straight and bend at your knees or hips. › Get help if the load is too heavy for you to lift alone. 6. Relieve stress Get some exercise, socialize, go to a movie or try meditating to help you relieve tension and shrug off the stresses of every day. 7. Quit smoking 4 Smoking reduces the blood flow and nutrients to the lower back. It also slows healing. Talk with your doctor about ways to quit. Sources: 1.

Exercise regularly Regular, low-impact exercise increases balance and strength. It also helps keep your back and abdominal muscles strong. Always talk to your doctor before starting any exercise program. Your doctor may recommend one or more of the following. 1,2 › Strength training: Work in back-strengthening and stretching exercises at least two days a week. › Balance exercises: Tai chi or yoga can help increase your balance. › Aerobic exercise: Fast-walking and swimming are good examples of low-impact, aerobic activities that get your heart pumping and keep your heart rate up while you’re exercising. Try getting at least 150 minutes of moderate-intensity aerobic activity (such as brisk walking) a week. You can even do 10 minutes at a time. Be sure to warm up to help your muscles transition from cold to warm, and help prevent injury. 2. Eat a healthy diet Yes, what you eat can affect the health of your spine. So, fill your plate with plenty of veggies, fruits, whole grains and lean proteins. In particular, calcium and Vitamin D can help keep your bones strong and prevent osteoporosis, which can lead to bone fractures that cause back pain. 2 Calcium is found in dairy products (milk, cheese and yogurt), green leafy vegetables such as kale and collard greens, tofu, and calcium-fortified products such as orange juice, soy milk and cereals. Vitamin D is made in your skin through the absorption of sunlight. You can also get this important nutrient from foods such as salmon, tuna, eggs, cheese and fortified dairy products, orange juice and cereals. Learn how precertification works for high-tech imaging. PLAN FOR YOUR SCAN Precertification is a review process that determines whether a procedure, treatment or service is medically appropriate. High-tech imaging, such as computed tomography (CT), magnetic resonance imaging (MRI) and positron emission tomography (PET) scans, requires precertification. For certain plan types, precertification for high-tech imaging will direct you to a specific site of care in your area. We have this process in place to help protect you from unnecessary cost, unnecessary radiation exposure and surprise bills. Here’s how it works. APPROVED You and your provider are notified Compare costs Cigna may call you to discuss lower-cost settings Once approved, schedule your appointment NOT APPROVED You and your provider are notified Consider alternatives Contact your provider for options Discuss or appeal Your provider may speak with Cigna’s medical director You and your provider decide you need a CT, MRI or PET scan. Your health care provider must complete the needed information for review. Your precertification request is reviewed using established medical criteria for that procedure. Now is a good time to go to myCigna.com to view in-network solutions and compare pricing to help you find the best site of care for you. Who is in charge of precertification? If your provider is in-network, he or she will send in your precertification request.* If you decide to use an out-of-network provider, you assume responsibility for the precertification process. Your health care provider can provide guidance on how to submit the request. How long does it take? Once your provider has completed and submitted your paperwork, a routine review takes about five business days.** You will receive a letter with the decision (approved or denied) and the details of the decision. For more immediate notification, visit myCigna.com . Remember, for urgent care center and emergency room treatments, precertification is not required. At Cigna, we’re with you every step of the way. For more information, visit myCigna.com or call the number on the back of your Cigna ID card. * In certain cases, your provider will give this information to an ancillary company we work with that helps manage these requests. ** Timing assumes all necessary clinical information has been submitted by the provider. If information is missing, approval may be delayed. This time period may be shortened according to applicable state law.

What is diabetes? 2 The simple definition of diabetes is a disease that happens when you have a high level of glucose (also called blood sugar) in your blood. But to truly understand what diabetes is, it’s helpful to understand how it occurs. Did you know that 29.1 million people in the United States have diabetes, and an estimated 86 million people age 20 years or older have prediabetes? And, one in four people who have diabetes don’t even know they have it. 1 That’s why it’s so important to understand what diabetes is, and how to recognize the signs. After all, the more you know, the more informed decisions you can make about your health. UNDERSTANDING DIABETES Start with the basics. 903502 02/17 Blood glucose is your main source of energy. It comes from the food you eat. Insulin, a hormone made by the pancreas, helps glucose from food get into your cells to be used for energy. If your body doesn’t produce enough insulin or the insulin doesn’t work the way it should, glucose can stay i n your blood and not reach your cells. If your blood glucose levels get too high, this can cause diabetes or prediabetes . What is prediabetes? Prediabetes is when the amount of glucose in your blood is higher than normal, but not quite high enough to be considered diabetes. With prediabetes your chances of getting type 2 diabetes are higher. If caught early enough, you can delay or prevent the development of diabetes by making healthy lifestyle changes. 3 HERE’S AN AT-A-GLANCE VIEW: Have questions about accessing virtual counseling through Cigna’s network of providers* or your employee assistance program (EAP)?** Start here. Should you have any additional questions, feel free to call the number on your Cigna ID card, anytime. Q. What kind of device can I use? A. Use your smartphone, tablet or computer with camera for virtual counseling. Q. Will the provider need to see me in person first? A. You can schedule virtual counseling appointments based on your provider’s availability. Depending on your reason for treatment, your provider might require that you been seen face-to-face first. Q. How much will it cost? A. Access this care as part of your behavioral health benefits under your employer’s health plan – and/or employee assistance program. Your out-of-pocket cost is the same as a behavioral health outpatient office visit. There’s no cost to you for EAP services, for the same number of covered EAP sessions.** Q. Does this include telephone sessions? A. Virtual counseling is video-based and does not require a prior authorization because it’s seen as a substitute for face-to face therapy. However, if phone sessions are needed, a prior authorization is required. See your EAP materials or plan documents for a complete list of covered behavioral health services.

8 EyeMed and Delta Dental Reminders 1/2 October 21, 2014 Make a Date for Your Eyes: Your Annual Exam Getting your eyes checked can help you be the vision of health. You may think you need an eye exam only when it’s time to update your eyewear prescription. But the truth is, eye exams are about a lot more than seeing whether you need a new pair of glasses or contacts. Comprehensive eye exams play an important role in your overall wellness, and you should get one every year for optimal vision health. Besides measuring your vision, regular eye exams can help identify early signs of certain chronic health conditions, including high blood pressure, diabetes and heart disease. During an eye exam, your doctor will check all aspects of your vision, including your eye’s structure and how well the eyes work together. Based on the exam results, your doctor will recommend a solution that is right for your eye health and vision care needs. Annual eye exams enable your doctor to monitor the health of your eyes and track changes that can occur from year to year. For example, subtle changes in the retina can be a warning sign of high blood pressure. So even if you don’t need vision correction, it’s important to take charge of your eye care. When you get your eyes checked every year, you’re helping your eyes—and possibly your whole body—stay well. 1. “8 Health Problems That Can Be Detected Through an Eye Exam”, AARP, November 15, 2021, https://www.aarp.org/health/conditions-treatments/info-2021/eye-exam-health.html. 1 1 1 These materials are designed to provide general information regarding health care topics, do not constitute professional advice nor establish any standard of care, and are provided without representations or warranties of any kind.

Top 401k Banner from last issue 9 We all know that diversification can be good for your portfolio because it means you’re less reliant on one type of investment to do well. Beyond just having a mix of equities (stocks) and bonds, you should also consider having a mix of different investment classes within each. That way, you’re exposed to multiple types of invest - ments and ultimately creating a more well-rounded portfolio. A CLOSER LOOK AT EQUITY DIVERSIFICATION When it comes to equity investments, there are a few key distinctions you’ll want to keep in mind: size, country, and style. Size One way to increase the diversifica - tion of your investments in compa - nies is to make sure you’re investing in companies of different sizes. Com - panies are usually broken down into three categories by size, and their size is determined by their market capital - ization, or market cap for short. (That’s the technical term for the value of the company.) • A small cap stock generally has a market capitalization of under $2 billion. • A medium cap stock generally has a market capitalization be - tween $2 billion and $10 billion. • A large cap stock generally has a market capitalization over $10 billion. Investing in all three can help diversify your portfolio because they can each experience different risk and return patterns. Country There are two major types of equity investments you can make when it comes to the region you’re investing in: domestic and international. If you’re building a portfolio of ETFs, which give you access and exposure to hundreds of investments with a sin - gle fund, you’ll also see a third category based on country: global. A global ETF is one that contains stocks from both domestic and international companies. When you’re diversifying between in - ternational and domestic investments, it’s important to understand that they do differ when it comes to their risk lev - els: International investments expose you to currency fluctuations, and some international investments are more vol - atile than others. Style There are two different investing styles you can diversify between when it comes to an ETF based portfolio: growth and value. Growth investing aims to invest in com - panies that are poised to outgrow the general market, whereas value invest - ing aims to invest in companies whose stocks are relatively cheap based on an analysis of the company and the mar - ket it operates in. You can find ETFs that are built to track indexes that are built on each in - vestment style, which is a great way to expose your investments to each style without having to do all of the analysis yourself.
