a. Return on net operating assets (RNOA) = Net Operating Income after tax / Average Net Operating Assets

Net Operating Income after Tax                                          HAL                SLB

Net Income (before tax)                                                        2,124             2,688

Add : Pre tax net non operating Expense                             653                 426

Net Operating Income before Tax                                      2,777                3,114

Marginal Tax Rate                                                                  22%                 19%

Less Tax Expense                                                                  -611                 -592

Net Operating Income after tax                                       2,166               2,522

Net Income before tax =  (Net Income (after tax)*1/(1 -Tax Rate)

Hal = 1,657 * 1/(1 - 22%)

= $2,124

SLB = 2,177 1/(1 - 22%)

= $2,688

Average Operating Assets                                                23,361         67,836

Average Operating Liability                                               5,888          16,499

Average Net Operating Assets                                      17,473           51,337

B. Net Operating Profit Margin = Net Operating Profits after tax/ Total Revenue

Net Operating Income after tax                                         2,166           2,522

Total Revenue                                                                   23,995         32,815

Net Operating Asset Turnover = Total Revenue/ Average Net Operating Assets

                                                                         HAL               SLB

Total Revenue                                                  23,995           32,815

Average Net Operating Assets                        17,473            51,337
