The government said on Monday banks have exposure of $336 million in US-based investment bank Lehman Brothers, which has filed for bankruptcy.

The banks' exposure to Lehman Brothers is $336 million (Rs 1,580 crore) as on September 30, Finance Minister P Chidambaram told Lok Sabha in a written reply.

The exposure mainly consisted of investments in floating rate notes, nastro balances, bank guarantees, forex exposures, etc, he said.

The banks have made aggregate provision of $47.3 million (about Rs 220 crore) on these exposures, he added.

The above figure has been arrived after RBI's assessment in the light of recent developments relating to failure of some large financial institutions in the USA and Europe representing investment banking, insurance and commercial banking segment, he said.

On the sub-prime, finance minister said it has been observed that none of the Indian banks and foreign banks (operations in India) had any direct exposure to sub-prime mortgage market in the USA and other markets and no direct impact could be seen.

However, a few banks had mark-to-market losses in their overseas operations, he said, adding some of the Indian banks with overseas operations though not having any direct exposure to the US sub-prime markets, invested in certain collateralised debt obligation which had a few underlying entities having sub-prime exposure.
