What the day will look like on one of our actuarial teams We offer four exciting paths from which to choose, each with an outstanding opportunity as you begin to establish your career. Retirement Consulting Pension and retirement plans have evolving financial implications for employers. Actuaries within retirement consulting work directly with our clients' management teams to assess the costs associated with these commitments. You will have access to a variety of areas during your internship, including the ever-important annual pension valuations, in which actuaries collect census data from clients and perform analysis and reporting to help our clients assess the ongoing financial health of their pension plans. Responsibilities include: Crafting projections (both stochastic and deterministic) of long-term financial information for pension and other post-retirement benefit plans as well as coordination of asset-liability analysis and due-diligence of M&A activities. Design and costing of new retirement programs, programming of innovative pension admin systems, pension benefits calculations and union negotiation strategies as well as quantitative comparison of comprehensive employee benefit programs for groups of employers. Health and Benefits (H&B) Consulting Employer-sponsored health and welfare benefit programs form the foundation of the U.S. health care system. These programs have evolved over time as employers have attempted to handle the changing needs of employees, rising program costs and the impact of new legislation while supporting their human resource and business strategies. Our interns collaborate directly with clients to develop welfare benefit strategies. This process involves strategic assessments of the health care market, key trends and the identification of new and innovative solutions to employer problems. The technical and analytical skills H&B actuaries bring to this process are essential to our H&B consulting business. Among the various areas of exposure are: Evaluation of plan design and costs relative to benchmarks and rate-setting for self-insured plans including the analysis of medical and prescription drug network changes. Employee contribution rate development and scenario analysis, analysis of plan renewals for appropriateness and carrier bid financial evaluations and the opportunity to conduct retiree medical and disability plan valuations.
