OREANDA-NEWS. The Idemitsu Group's net sales for the six months ended September 30, 2013 were JPN 2,347.0 billion, an increase of 14.4% compared with the same period of the preceding year, due partly to increased import prices for crude oil resulting from the weakened Japanese yen.

Operating income climbed by 84.1% from the same period of the previous year to JPN 51.4 billion, affected by a valuation gain on inventories resulting from the increased Japanese yen-denominated crude oil prices.

Net of non-operating income and expenses resulted in expenses of JPN 4.0 billion, consistent with the same period of last year, and consequently, ordinary income for the six months ended September 30, 2013 was JPN 47.4 billion, up 98.3% from the same period of the previous year.

Net income for the six months ended September 30, 2013 was JPN 38.8 billion, up JPN 36.4 billion compared with the same period of the preceding year, mainly due to a combination of the results above and increased extraordinary income assisted by insurance proceeds.
