Tokio Marine Holdings has reported a ¥87.38 billion ($904 million) profit for the nine months to December 31, compared with a ¥19 billion ($190 million) loss in the previous corresponding period, which was affected by tax losses.

The company – parent of Tokio Marine & Nichido Fire Insurance, Nisshin Fire & Marine, E.design Insurance and Tokio Marine & Nichido Life Insurance – has reported income of ¥2.69 trillion ($27.8 billion), down marginally on the previous corresponding period.

Premiums written were boosted by the acquisition of US insurer Delphi last year and by growth in domestic non-life insurance.

The group’s overseas subsidiaries increased their profit contribution on fewer catastrophe losses. Profit before tax and extraordinary items rose 21% to ¥133.46 billion ($1.38 billion).

A stronger domestic stock market increased income by 35% to ¥323.85 billion ($3.35 billion).

Group underwriting income fell 4% to ¥2.31 trillion ($23.9 billion) while underwriting expenses rose 5% to ¥2.13 trillion ($22 billion).

Tokio Marine & Nichido Fire reported a combined ratio of 97.5%.

Tokio Marine Group has increased its estimated losses from Hurricane Sandy to ¥22 billion ($227.7 million) due to yen depreciation, which will be reflected in the fourth-quarter result.
