Israeli holding company Koor Industries Ltd. (KOR.TV) said Sunday that its net loss for the second quarter totaled 1.92 billion shekels ($53 million) due to the declining price of shares in Credit Suisse Group (CS), one of its investments.

In the second quarter of 2010, Koor reported a net profit of ILS35.4 million. Revenue was ILS421 million, up slightly from ILS407 million.

Koor had warned that it would report a loss from the declining price in shares of Credit Suisse, which it has been buying and selling since 2008. Koor recently reduced its holding in Credit Suisse to 2.14% from 3.21%, due to the declining share price and the need to pay back lenders that loaned it money to buy the Swiss bank shares. Koor said it expects the Credit Suisse investment to continue having a negative effect on its financial situation. It said it would report a loss of ILS91 million in its third quarter financial results due to the investment.

At 1000 GMT, shares of Koor were up ILS0.01, or 0.03%, at ILS30.78, in a higher Tel Aviv market.
