Explanation

1. Operating Income or EBIT is linked to Return on Capital for both regular definition and Joel Greenblatt’s definition.

Wisconsin Energy Corp's annualized Return on Capital (ROC) for the quarter that ended in Sep. 2014 is calculated as:

Return on Capital (ROC)(Q: Sep. 2014 )
=(EBIT - Adjusted Taxes)/Average Total Capital
=Net Income/( (Total Capital (Q: Jun. 2014 ) + Total Capital (Q: Sep. 2014 ))/ 2 )
=505.2/( (12852.4 + 12876.9)/ 2 )
=505.2/12864.65
=3.93 %

where

Total Capital(Q: Jun. 2014 )
=Book Value of Debt + Book Value of Equity - Cash
=Total Current Assets + Property, Plant and Equipment + Other Current Assets
=1285.5 + 11024 + 542.9
=12852.4

Total Capital(Q: Sep. 2014 )
=Book Value of Debt + Book Value of Equity - Cash
=Total Current Assets + Property, Plant and Equipment + Other Current Assets
=1274.5 + 11134.9 + 467.5
=12876.9

Note: The Net Income data used here is four times the quarterly (Sep. 2014) net income data.

2. Joel Greenblatt’s definition of Return on Capital:

Wisconsin Energy Corp's annualized Return on Capital (Joel Greenblatt’s) for the quarter that ended in Sep. 2014 is calculated as:

ROC (Joel Greenblatt’s)(Q: Sep. 2014 )
=EBIT/Average of (Net fixed Assets + Net Working Capital)
=Operating Income/Average of (Net PPE+Net Working Capital)
     Q: Jun. 2014  Q: Sep. 2014
=Operating Income/( ( (Net PPE + Net Working Capital) + (Net PPE + Net Working Capital) )/2 )
=984.4/( ( (11024 + max(726.5, 0)) + (11134.9 + max(643.7, 0)) )/2 )
=984.4/( ( 11750.5 + 11778.6 )/2 )
=984.4/11764.55
=8.37 %

where Working Capital is:

Working Capital(Q: Jun. 2014 )
=(Accts Rec. + Inventory + Other Curr. Ass.) - (Accts Pay. + Defer. Rev. + Other Curr. Liab.)
=(404.9 + 304.3 + 542.9) - (358.9 + 0 + 166.7)
=726.5

Working Capital(Q: Sep. 2014 )
=(Accts Rec. + Inventory + Other Curr. Ass.) - (Accts Pay. + Defer. Rev. + Other Curr. Liab.)
=(339 + 379.3 + 467.5) - (386.4 + 0 + 155.7)
=643.7

When net working capital is negative, 0 is used.

Note: The Operating Income data used here is four times the quarterly (Sep. 2014) operating income data.

Be Aware

Compared with a company’s EBITDA margin, Operating Margin can be manipulated by adjusting the rate of depreciation, depletion and amortization (DDA).

If a company is facing competition, its Operating Margin may decline. Often the Operating Margin declines well before the company’s revenue or even profit decline. Therefore, Operating Margin is a very important indicator of whether the company is facing problems.

For instance, by 2012, Nokia (NOK)’s problems were well known and its stock had lost more than 90% of its market value since 2007. But Nokia’s Operating Margin had already been in decline since 2002, although its earnings per share were still rising. Investors who paid attention to Operating Margin would have avoided this huge loss. The same can be said for Research-in-Motion (RIMM).

Therefore, Operating Margin is a very important screening filter for GuruFocus. GuruFocus’s Buffett-Munger screener requires that the profit margin is either consistent or expanding. The Model Portfolio of the Buffett-Munger screener has outperformed the market every year since inception in 2009.
