- Divesting non core operations(Shell/Rio Tinto/BHP/GE Financial)
- Realigning reporting/organization structure as shown in segment reporting(nearly all firms!)
- Taking on debt to purchase battered down assets elsewhere(Bharti Airtel, Tata Steel)
- Using surplus cash to buy expensive assets(Microsoft, HP, Google)
My view:- SOTP(Sum of the parts) method would again rule the waves for Beta calculation. But before signing of on that elegant NPV calculation, ask yourself whether you can live with the limitations in the calculation of the Beta value presented to you. Expect plenty of research on this in times to come.
