Longer Time Horizon Is Better for Triple Bottom Line

A longer time horizon can provide insights that lead to better results for all three elements of the Triple Bottom Line: People, Planet, AND Profit. A longer view is also consistent with the investment approach practiced by Warren Buffett, America’s most successful investor.


Capital investments at companies are generally made on the basis of return on investment (ROI) or time to break-even. The typical break-even period at larger firms is 2-3 years, and there are many opportunities that fit within that timeframe. When assessing capital investments that also have an environmental and social benefit, then a longer break-even timeframe makes more sense.


Let’s look at a simple example of buying new pumps in a manufacturing firm. The old pumps work just fine for now, but use a lot of electricity.

  • Installing new pumps would save 25% per year on electrical costs

  • The pumps are 20 years old, and have an expected additional life of 10 years

  • As the pumps age, there is an increasing risk of break down and work stoppages

  • Company policy on capital investments is a 3 year break-even timeframe


Due to the 3 year break-even requirement, the pumps are not purchased. In years 1-4, the financial benefits of not purchasing the pumps include:

  • Higher profitability for the firm

  • Improved cash flow

  • Higher bonuses for the management team

  • Higher company stock price (if investors don’t dig too deep on how decisions are made)


In years 5-10, the following happens as compared to having purchased the pumps:

  • Lower profitability due to missed savings on electrical costs

  • Decreased cash flow

  • Higher risk of manufacturing stoppages due to a malfunctioning pump

  • Lower bonuses for the management team

  • Lower stock price


If the firm decides to purchase the pumps now despite the longer time to recoup the cost, the following benefits accrue over the entire 10 year period:

  • Higher profits

  • Improved cash flow after 4 years

  • Lower risk of expensive manufacturing stoppages

  • Decreased impact on the environment from lower levels of energy use

  • Expected remaining 20 year life span for installed pumps

  • An accomplishment to record in the Corporate Social Responsibility (CSR) report

  • Improved employee morale from seeing the company “doing the right thing”

  • Financial benefits accruing from improved company reputation and more committed employees


When an investment decision has a social or environmental impact in addition to a financial impact, then the firm should use a longer than normal investment timeframe. In doing so, it will position itself for better results in each of the elements of the Triple Bottom Line – including profits.


(Disclaimer: For those of you in manufacturing, please note that data used for pump life spans and energy efficiency is for demonstration purposes only. Your actual results may be quite different. Nevertheless, the basic precept of using a longer investment time frame should still hold true.)
