Yandex, Sberbank, Mobile telesystems I had also untilll recently but sold them....It's more about a safety net gazprom one has to look on for an investment..

1st it's a safe investment with almost zero risk unless world war III strikes upon us
2 nd the dividend hikes each yr, you basically get for free at this price....think they raised it with 2% or so this year but once all these pipelines are c'ing online I guess the dividends between now and 2020 will be double the amount as of today.....building these pipelines is a multi billion dollar cost..so I guess once these costs are out of the way, more profits will arise for current shareholders.
Gazprom was normally planning to distribute 50% of there net profits to the shareholders, but like I said it in the previous sentence....these boosts are on a hold while building the pipeline network in different areas of the world now...
3 it's safe to put a decent amount of money into it without caring or thinking you will wake up the next day with a monster loss...as it is with many other investments sure bets are hard to find.
4 Time and patience is all one need overhere, don't mind waiting 3-4 yrs quadruppling my initial investment, I know it will get there ....the timeline is alway's a friend in decent investments
5 Putin said Gazprom will restore it's own value when that moment arises...
