  Zurich North America

  Jan 1997 - Jan 1999

  Actuarial Analyst

  I worked in actuarial pricing, first in middle markets commercial insurance, then in large accounts property.In middle market commercial insurance, we mainly did 2 semi-annual reviews of the profitability of our books of business, comparing premium dollars coming in the door to claims dollars going out the door, adjusting the statistics to ultimate loss levels and trending loss numbers to expected levels over the new exposure period, computing "loss ratios" (claim dollars paid out/premium dollars coming in), adjusting again for expected claims payout patterns and investment income on claims dollars expected to be paid out well after the time premiums are collected, and then comparing the final implied internal rate of return to the company's cost of capital to keep the company profitable, so that we would neither go broke from losses, nor have our investors think our actual company's return on investment isn't worth our industry's risk, sell all our stock, and have our market value plummet like a rock to $0.00 :)We also worked with Compliance to justify the rate increases we recommended and Underwiting and Management approved to the state Departments of Insurance (DOIs).Other than that, we just worked on ad hoc projects: an underwriter would have some "small" book of business, and we'd use our spreadsheets/computer programs/etc. from the Major State Reviews to do "little reviews" of their target market program.

  Instant Auto Insurance

  Sept 1999 - Oct 1999

  Product Analyst

  I worked on new state rollout. Instant Auto was a new, growing personal auto insurance company, so we were constantly trying to begin writing business in new states, and I assisted with gathering data on the "market conditions" in those states and did some work on the ratings tables for those states (but not much work on the ratings tables).

I once made a really huge spreadsheet that had all the data you could possibly want to do a California filing (California has a legendarily hard "prior approval" review process - they were probably the hardest in the nation, with Texas a close second): you just selected some drop-down menus and filled in a few fields on the first couple of pages of the spreadheet, and then you just hit "Print" on the next 5 pages or so - the "print pages" were formatted to look just like the DOI's forms, and I never had a complaint from the DOI about not using their official forms. [Edit: It would be fun to try to reproduce this in WAMP.]Other than that, we just worked on ad hoc projects: an underwriter would have some "small" book of business, and we'd use our spreadsheets/computer programs/etc. from the Major State Reviews to do "little reviews" of their target market program.
