Original research

Bengen first published his findings in 1994, based on analyzing data for retirements from the years 1926 to 1976 — that's 50 years of data. He considered a hypothetical, conservative portfolio comprising 50% large-cap stocks and 50% intermediate-term Treasury bonds held in a tax-advantaged account and rebalanced annually. A 4% inflation-adjusted withdrawal was the highest sustainable rate in the worst-case scenario — retirement in October 1968. This was the beginning of a bear market and a long period of high inflation. All other retirement years had higher sustainable rates, some as high as 10% or more.[1]

Of course, no one can predict the future, which is why Bengen suggested the worst-case scenario as a sustainable rate. He later adjusted it slightly upward to 4.5%, based on a more diverse portfolio comprising 30% large-cap stocks, 20% small-cap stocks, and 50% intermediate-term Treasuries.[2]

New research

Now that we have an understanding of Bengen's original research, we'd like to take a look at a more recent analysis with our clients from Oneok. In October , Bengen published new research that attempts to project a sustainable withdrawal rate based on two key factors at the time of retirement: stock market valuation and inflation (annual change in the Consumer Price Index). In theory, when the market is expensive, it has less potential to grow, and sustaining increased withdrawals over time may be more difficult. On the other hand, lower inflation means lower inflation-adjusted withdrawals, allowing a higher initial rate. For example, a $40,000 first-year withdrawal becomes an $84,000 withdrawal after 20 years with a 4% annual inflation increase but just $58,000 with a 2% increase.

To measure market valuation, Bengen used the Shiller CAPE, the cyclically adjusted price-earnings ratio for the S&P 500 index developed by Nobel laureate Robert Shiller. The price-earnings (P/E) ratio of a stock is the share price divided by its earnings per share for the previous 12 months. For example, if a stock is priced at $100 and the earnings per share is $4, the P/E ratio would be 25. The Shiller CAPE divides the total share price of stocks in the S&P 500 index by average inflation-adjusted earnings over 10 years.

5% rule?

Bengen once again used historical data, this time, for over 60 years of retirement. Analyzing retirement dates from 1926 to 1990, Bengen found a clear correlation between market valuation and inflation at the time of retirement and the maximum sustainable withdrawal rate. Historically, rates ranged from as low as 4.5% to as high as 13%, but the scenarios that supported high rates were unusual, with very low market valuations and/or deflation rather than inflation.[3]

For the majority of the last 25 years, the United States has experienced high market valuations, and inflation has been low since the Great Recession.[4-5] In a high-valuation, low-inflation scenario at the time of retirement, Bengen found that a 5% initial withdrawal rate was sustainable over 30 years.[6] While not a big difference from the 4% rule, this suggests retirees could make larger initial withdrawals, particularly in a low-inflation environment. But in a high inflation environment withdrawals should decrease.

One caveat is that current market valuation is extremely high: The S&P 500 index had a CAPE of 34.19 at the end of , a level only reached (and exceeded) during the late-1990s dot-com boom and higher than any of the scenarios in Bengen's research.[7] His range for a 5% withdrawal rate is a CAPE of 23 or higher, with inflation between 0% and 2.5%.[8] (Inflation was 1.2% in November .)[9] Bengen's research suggests that if market valuation drops near the historical mean of 16.77, a withdrawal rate of 6% might be sustainable as long as inflation is 5% or lower. On the other hand, if valuation remains high and inflation surpasses 2.5%, the maximum sustainable rate might be 4.5%.[10]

It's important for Oneok employees to keep in mind that these projections are based on historical scenarios and a hypothetical portfolio, and there is no guarantee that your portfolio will perform in a similar manner. Also remember that these calculations are based on annual inflation-adjusted withdrawals, and you might choose not to increase withdrawals in some years or use other criteria to make adjustments, such as market performance.

Although there is no assurance that working with a financial professional will improve investment results, a professional can evaluate your objectives and available resources and help you consider appropriate long-term financial strategies, including your withdrawal strategy.

We'd like to remind our clients from Oneok that all investments are subject to market fluctuation, risk, and loss of principal. When sold, investments may be worth more or less than their original cost. U.S. Treasury securities are guaranteed by the federal government as to the timely payment of principal and interest. The principal value of Treasury securities fluctuates with market conditions. If not held to maturity, they could be worth more or less than the original amount paid. Asset allocation and diversification are methods used to help manage investment risk; they do not guarantee a profit or protect against investment loss. Rebalancing involves selling some investments in order to buy others; selling investments in a taxable account could result in a tax liability.

Building a sustainable withdrawal strategy requires knowing every income source Oneok makes available in retirement. At the core of your retirement package, Oneok maintains an active defined benefit pension plan, which means eligible employees continue to accrue benefits based on years of service and compensation, meaning eligible employees continue to accrue benefits based on years of service and compensation. If you are eligible for a lump sum payout, IRS Section 417(e) segment rates determine how the future annuity stream converts to a present-value payment - rising rates compress the lump sum, so monitoring the plan's stability period and lookback month is critical before you lock in your election date. The choice between a single-life annuity, a joint-and-survivor option, or a lump sum (where available) is generally irrevocable once made, and timing that decision relative to interest rate conditions can meaningfully affect your retirement income picture.

Your healthcare coverage at Oneok is equally important: Oneok provides continued medical coverage to eligible retirees, which can bridge the gap between retirement and Medicare eligibility at age 65 or serve as a supplement to Medicare thereafter. Confirming the service and age requirements for retiree coverage, and understanding your premium contribution, is an important step in building an accurate healthcare cost projection. Coordinating Oneok's retiree coverage with Medicare Part B and Part D enrollment timing can also reduce duplication and avoid late-enrollment penalties. A comprehensive retirement plan that accounts for each element of your Oneok benefits package is the best way to understand what lies ahead.

Flps Must Comply With State Law and IRS Requirements

An FLP is subject to more restrictive rules than other forms of business entities. Care must be taken to create a valid FLP in the eyes of the state and the IRS. An FLP will be recognized only if it is formed for a valid business purpose. The FLP form will be disregarded if the IRS or the state finds that it was formed solely to avoid taxes.

Some specific purposes for creating an FLP include:

• To adopt a family succession plan
• To simplify annual gifting by the senior generation
• To minimize income, gift, and estate taxes
• To protect assets from potential creditors
• To protect assets from waste by heirs
• To consolidate assets into a single entity
• To keep the business in the family
• To decrease estate and probate costs

Additionally, an FLP may own a closely held business (other than a corporation that has made an election to be taxed as an 'S' corporation), real estate, marketable securities, or almost any other investment asset. Homes, cottages, or other personal use assets are normally not suitable for an FLP.

Tips For Forming And Maintaining A Valid FLP:

• Have one or more substantial nontax purposes for creating the FLP, such as asset protection
• Keep good records
• Create the FLP while you're still in good health
• Observe all legal formalities when creating the FLP and while operating the business
• Hire an independent appraiser to value assets going into the FLP
• Transfer legal title of assets going into the FLP
• Put only business assets into the FLP — don't put any personal assets into the FLP
• If you do put personal assets into the FLP, such as your home, pay fair market rent for their use
• Don't commingle FLP assets and personal assets — keep them separate
• Never use FLP assets for personal purposes
• Keep enough assets outside the FLP to pay for personal expenses
• Distribute income to partners pro rata
