However, five Indian companies -- scam-hit IT firm Satyam Computer, realty firm Unitech, Suzlon Energy and two Anil Ambani group firms Reliance Power and Reliance Capital – have been dropped out of the Forbes 'Global 2000 List' this year.

Four Indian companies, Hero Honda Motors, Sun Pharma, Indian Bank and Jindal Steel and Power Ltd are the new entrants to the list.

Mukesh Ambani-promoted RIL, State Bank of India, and Oil and Natural Gas Corporation are among the top 200 companies ranked 121st, 150th and 152nd, respectively, on the list.

All the three top Indian firms have improved their ranks considerably from their last year's positions, wherein RIL had been 193rd, SBI at 219th spot, while ONGC was ranked 198th.

Overall, the list is topped by industrial conglomerate General Electric, followed by Dutch oil and gas major Royal Dutch Shell, Japan's Toyota Motor, ExxonMobil and UK's BP in that order.

The rankings have been compiled on the basis of a composite score of sales, profit, assets and market capitalisation.

However, British banking giant HSBC Holdings has dropped to the sixth place this year from its numero uno position in the last year's list.

The other top Indian firms on the list include Indian Oil (207th), NTPC (317th), ICICI Bank (329th), Tata Steel (463rd) and Bharti Airtel (508th).

The Indian presence is almost evenly divided among the private and state-run companies. While none of the Indian companies has managed to find a place among the top 100 firms this year as well, the elite club includes a firm run by person of Indian origin.

Lakshmi Mittal-headed steel behemoth ArcelorMittal is at 41st position. However, Vikram Pandit-run banking giant Citigroup has dropped to 472nd rank this year.

Further, Indra Nooyi-run beverage major PepsiCo has been ranked 115th, India-origin Francisco D'Souza-headed Cognizant Technology Solutions at 1389th place. Motorola, headed by Sanjay Jha, is at 658th place.

According to Forbes, the Global 2,000 companies have combined revenue of 32 trillion dollars, 1.6 trillion dollars in profit, 125 trillion dollars in assets and 20 trillion dollars in market capitalisation.

Other Indian companies on the list include SAIL (582), Reliance Communication (689), Larsen & Toubro (773), BPCL(795), BHEL(796), HDFC (808), TCS(834), Hindalco Industries (848), HDFC Bank (864), DLF (883), Infosys( 891), Punjab National bank (946), ITC (987), Wipro (989), Bank of India (997), HPCL (1,002), GAIL (1,037) and NMDC (1,057).
