Challenge and Reward

The Actuarial Case Competition is Bruin Actuarial Society's largest event of each Winter Quarter. Teams of students work together on a case provided by a sponsor of the Society and present their findings and recommendations. The cases are representative of professional actuaries' real-life work and provide a valuable experience for students to use their mathematical knowledge and technical skills beyond the classroom. Teams that advance to the final round have the opportunity to present in front of a panel of judges from firms throught the region and compete for recognition and a cash prize.

Past Competitions

The 2017 Case Competition tasked students with pricing 2018 health insurance premiums based on historical membership and claims data. An excerpt from the assignment follows:

"You are an actuary at BruinCare, a health insurance company, and need to price individual health insurance premiums for 2018. BruinCare has been a part of the ACA exchanges for the past three years, providing healthcare coverage and services in regions 1 through 3 in California. The state government intends to rebrand these rating regions in order to create renewed interest in healthcare enrollment. Please provide and refer to your new region names throughout the case study.

Your job will be to use historical 2016 data to project for 2018. You will need to use your company’s 2016 base data to calculate a set of premiums by projecting 2018 membership and claims to generate a representative single claims PMPM (Per-Member-Per-Month). This value will be used to calculate the Index Rate, Market Adjusted Index Rate, and Plan Adjusted Index Rate. Once you have your Plan Adjusted Index Rate, you will apply area factors, age calibration, and the age curve to arrive at your final individual premiums by region. [An attached] Excel workbook ... is the pricing model in which you will complete all of your calculations."

Kaiser Permanente's 2016 Bruin Actuarial Society Case Competition asked students to develop rating models and forecast rate increases, loss ratios, and financial results for various segments of a health insurer's business as the Affordable Care Act took hold. An excerpt follows:

"You are an Actuary at The University of California Health Insurance Company (“UCHIC” or “UC” for short).Your company is domiciled in Westwood, California. UC is a large health insurance company providing health insurance to large group employers, i.e., employers with more than 50 employees...

Your Actuarial analysis, at a minimum, should show the following:

  1. Develop large group rating models and forecast rate increases, loss ratios and financial results for UC’s large group business considering the early renewals of UC’s small-large groups and then the remaining large groups that did not renew early. Do not forget that you promised Leadership a financial review of extending the offer that groups “could not refuse” to all small-large group renewals in 2016.
  2. Develop small group rating models from the consultant’s assumptions and then calculating loss ratios and financial results considering the existing UC groups that will become small groups and the new business UC can expect from entering the small group market
  3. Develop individual rating models from the consultant’s assumptions and then calculating loss ratios and financial results
  4. For each of the new business lines, consider different membership assumptions based on the consultant’s advice
  5. Summarize the projected financial results from the time periods 2016 and 2017 and from each business line"

The Third Annual Bruin Actuarial Society Case Competition tasked students with determining whether a public entity operating an aging fleet of vehicles should buy the newest optional safety features for its automobiles. An excerpt follows:

"Your actuarial firm, The Bruinators, provides property/casualty actuarial consulting services to UCLA. UCLA has a large fleet of aging autos, half of which will need to be replaced next year. UCLA is aware that over the past several years there has been a lot of innovation related to auto safety, and they have asked the Bruinators to investigate whether the new cars they purchase should include some of these features and also whether they should add safety devices to the half of their fleet that will not be replaced...

UCLA is self-insured for auto and workers’ compensation exposures. This means that rather than purchasing coverage from an insurance company UCLA directly pays for costs associated with auto accidents and work-related injuries to employees...

You will be expected to give a presentation that makes recommendations regarding what safety features UCLA should add to existing vehicles and should be purchased for the half of the fleet that is being replaced. You should address what you think will be the key concerns of the evaluators from each department. There may be some issues that you are not able to quantify to your satisfaction. That’s okay. Make an educated guess, and state any additional assumptions you needed to make. You are expected to be factual and unbiased; you have no investment in whether or not UCLA purchases any of the auto safety features.

At a minimum you will need to forecast ultimate costs associated with auto claims under two scenarios, one in which UCLA does not purchase any of the potential safety features and one in which they purchase the features you are recommending. If you recommend not purchasing any of the potential safety features, then you should explain why. You do not need to be concerned with the basic cost of each new car, only the incremental cost associated with any safety features you are recommending."
