There are two known terms in the investment jargon namely,
Return on Capital Employed.
Profit Growing Efficiency Level.
These two terms carry the same meaning.
To dwell more on it, minimum ROE or PGEL of a company over the past five years should be 15% or more. I mean it should be clocking higher level. Higher the ROE, better for the company's growth. Such companies need not raise the money from the bankers or lending institutions for further expansion. They can manage for the funds from within the internal accruals. Thus, not to serve the lenders on account of interest on loan.
