The Four Drivers of Value  •  105
Over this very long period, the nominal GDP growth in the United
States averaged just over 6 percent per year. If the investment projects
of a company are generally successful, the company will be able to
dependably grow its profits at a rate faster than this 6 percent (or so)
benchmark. The length of time it will be able to grow faster than this
benchmark will depend on various factors related to the competitive-
ness of the industry, the demand environment, and the investing skill
of its managers.
Seeing whether or not investments have been successful over time is
a simple matter of comparing OCP growth with nominal GDP . Lets look at
a few actual examples. Here is a graph of my calculation of Walmarts OCP
and OCP margin over the last 13 years:

Estimated Owners Cash Profit and OCP Margin for Walmart
Total Estimated OCP (LH) OCP Margin (RH)
As one might expect with such a large, mature firm, OCP margin
(shown on the right-hand axis) is very steady—barely breaking from the
3.5 to 4.5 percent range over the last 10 years. At the same time, its to-
tal OCP (shown on the left-hand axis) grew nicely as a result of increases
in revenues. Over the last seven years, Walmart has spent an average of
around 2 percent of its revenues on expansionary projects, implying that
