The measure of (in Marxian terms) "profit" comprises, on an after- tax basis: net rental income, net interest income, total executive salaries, total dividend income, and (net of properly computed capital consumption)
corporate retained earnings.

For us mathematicians such words as "properly computed" are vague.

What does "properly computed" mean?

The vagueness is quite intentional, because measurement of capital consumption involves guesstimation of the economic lifespan of every individual capital asset, plus an arbitrary allocation of that "moral and physical wear and tear" over periods of time in that lifespan. Accounting conventions and tax codes can be roughly accurate summations only by accident. Since fixed constant capital is consumed over time and so enters as value into the social gross product, the *magnitude* of that value in any accounting period must aggregate to a single number. But the impossibility of properly calculating capital consumption is far from the only, or worst, difficulty in the empirical calculation of aggregate surplus value. All the other components of surplus value, however well-defined in theory, likewise have very problematic empirical elements, especially involving the real incidence of taxation.
