Europe and the U.S. are trying to hit Russia's economy by restricting its access to Western finance, oil technology and arms. Here are the 15most important companies and individuals now subject to Western sanctions, imposed over the crisis in Ukraine: 1. Rosneft: Russia's biggest oil company; part owned byBP (BP) and partner to ExxonMobil (XOM). Has lost access to U.S. sources of long-term finance. Cash rich and can still export oil. Expected to complete its purchase of Morgan Stanley (MS)'s oil trading business. 2. Novatek: Russia's largest independent natural gas producer. Has lost access to new U.S. funding. France's Total (TOT) is a major shareholder and partner. 3. Sberbank (SBRCY): Russia's biggest bank, serving more than half the population of Russia and one million businesses. Has a joint venture with BNP Paribas (BNPQF) and millions of customers abroad. Can no longer raise medium and long-term finance in Europe. 4. VTB: Second biggest bank,provider of full range of financial services to clients in Russia and more than 20 countries. Shut out of European and U.S. financial markets. Says it's confident it will continue to be able to attract funds when needed, and promises to meet all obligations to clients and investors. 5. Gazprombank: A key player in financing Russia's energy sector, the mainstay of country's economy. Gazprom (GZPFY), which supplies Europe with about a third of its natural gas, is a major shareholder. Bank's dependence on U.S. markets is low and it can count on Russian state support given its importance to the economy. 6. Bank of Moscow: Controlled by VTB, its focus is on the domestic market and it has no plans to borrow on foreign markets. It has 9 million private customers and 100,000 corporate clients, mainly in the Moscow area. 7. Russian Agricultural Bank: 100% owned by the state, the bank is a major lender to farmers and Russia's large rural population. 8. VEB: Arranges payments for the Russian government; chairman is Russian Prime Minister Dmitry Medvedev. Bank will have to reduce its exposure to dollars in the future. Should be able to manage its financing through 2015 by tapping markets in other currencies, local investors and the Russian central bank. 9. United Shipbuilding Corp: Russia's biggest shipbuilder, it designs and constructs ships for the Russian navy. 10. Kalashnikov: Russia's largest firearms manufacturer; famous for its AK-47 rifles. Among nine Russian arms firms that have had U.S. assets frozen and have been banned from doing business with U.S. businesses or individuals. 11. Igor Sechin: Rosneft CEO and one of dozens of Russians who have had their assets frozen. Laughed off a sanctions-inspired fall in Rosneft's shares in March as a buying opportunity, but warned last week's blacklisting of the company was an attempt to target Russia's economy. Says U.S banks and investors would suffer from the move. 12. Yuri Kovalchuk: A close associate of Putin and largest shareholder in Bank Rossiya, which is also facing U.S. sanctions. Called Putin's "personal banker" by U.S. officials. Bank is Russia's 17th biggest and has major interests in oil and gas. Three subsidiaries are also on U.S. sanctions list. 13.
