19. 19 Financial Strategy: Cash Flow Sources As an operating holding company, Sistema has three major cash flow sources: Dividend Cash Flows –Starting in 2002 MTS has changed its policy of dividend distribution with payout levels established in a shareholder agreement between Sistema and Deutsche Telekom, which should provide holding company with sound cash upstream –In future, as our businesses mature, we expect dividends to become a significant recurring cash flow source for the holding company Income from Real Estate –Real Estate segment is different from our other business lines as it is capable to generate significant cashflows for the holding company in the short to mid term while other businesses (except for MTS) are at earlier stages of development Capital Gains Potential –We are quite flexible in respect of non-core asset disposals and are taking a tactical approach to managing our interests in these businesses In addition to three major sources, Sistema receives consulting/management fees which are generally balanced against holding companys administration costs
