There are just a couple of things almost all Interactive Brokers Group retirees need when they hit retirement: predictable income and protection against a cluster of risks, which include longevity risk, performance risk and sequence-of-returns risk.

In the past we have seen retiring Interactive Brokers Group employees utilize the "4% rule," where retirees take annual withdrawals start at 4% of the entire portfolio and increase with inflation. They then keep the remainder of the portfolio with at least 50% invested in equities. Based on historical data, this would give a Interactive Brokers Group retiree about 30 years of retirement income.

As the economy constantly changes, a number of factors may force prospective Interactive Brokers Group retirees to revisit the 4% rule. It may be worth considering annuities as an alternative.

As life expectancies increase, Interactive Brokers Group retirees need to prepare for expenses over a longer time frame. In the past we would plan for a 15 to 20 year retirement, but now we need to prepare for a 30 to 35 year retirement. What is available to assist meeting the 35-year time frame?

The annuity strategy can assist with a few of the pitfalls we see in the 4% rule. For example:

If you need $50,000 per year in retirement and need that for 30 years, you may need $1.2 million in fixed income at a 3% interest rate. BUT if you look to fund $50,000 for 30 years, you can cover that expense with $800,000 by choosing the annuity option.

The other pitfall with the 4% rule is that it may not reflect a client's risk tolerance. When you are accumulating assets, you can afford more volatility and can take on more risk than when in the retirement and withdrawal phase after leaving Interactive Brokers Group.

Also, should we see a drop in the market, you would be able to reduce your income using the 4% rule, which you cannot do if you choose an annuity option.

As you plan your transition from Interactive Brokers Group into retirement, understanding the company's benefit structure can help you make more informed decisions. According to publicly available information, Interactive Brokers Group does not maintain a traditional defined benefit pension plan, making your 401(k) plan and personal savings the primary vehicles for retirement income. Interactive Brokers Group does not appear to offer a formal retiree healthcare program, so healthcare coverage planning before Medicare eligibility at age 65 is an important consideration.
