Aon Cyclically Adjusted Revenue per Share Calculation

E10 is a concept invented by Prof. Robert Shiller, who uses E10 for his Shiller PE Ratio calculation. E10 is the average of the inflation adjusted earnings of a company over the past 10 years. The similar calculation is applied by GuruFocus to calculate the Cyclically Adjusted Revenue per Share and the Cyclically Adjusted PS Ratio. The Cyclically Adjusted Revenue per Share is the average of the inflation adjusted Revenue per Share of a company over the past 10 years.

What is Cyclically Adjusted Revenue per Share? How do we calculate Cyclically Adjusted Revenue per Share?

Cyclically Adjusted Revenue per Share is the average of the inflation adjusted Revenue per Share of a company over the past 10 years. Let's use an example to explain.

If we want to calculate the Cyclically Adjusted Revenue per Share of Wal-Mart (WMT) for Dec. 31, 2010, we need to have the inflation data and the revenue per share from 2001 through 2010.

We adjusted the 2001 revenue per share data with the total inflation from 2001 through 2010 to the equivalent revenue in 2010. If the total inflation from 2001 to 2010 is 40%, and Wal-Mart's revenue is $1 a share in 2001, then the 2001's equivalent revenue in 2010 is $1.4 a share. If Wal-Mart's revenue is $1 again in 2002, and the total inflation from 2002 through 2010 is 35%, then the equivalent 2002 revenue in 2010 is $1.35. So on and so forth, you get the equivalent revenue per share of past 10 years. Then you add them together and divided the sum by the count to get Cyclically Adjusted Revenue per Share.

Please note that we use the CPI data of the country/region where the company is headquartered. If the CPI data for that country/region is not available, then we will use the CPI data of the United States as default.

For example, Aon's adjusted Revenue per Share data for the three months ended in Jun. 2026 was:

Adj_RevenuePerShare= Revenue per Share /CPI of Jun. 2026 (Change)*Current CPI (Jun. 2026)
=345.302/128.6700*128.6700
=345.302

Current CPI (Jun. 2026) = 128.6700.
