Convenience store operator Lawson has reported its financial results for the six months ended August 2011.

Net profit fell 27% to ¥8.96bn (£68.6m) from ¥12.29bn (£90.6m) for the same period last year. The drop was due in part to losses related to new accounting standards. Operating profit experienced an 8% gain, while revenue increased 8.5% to ¥240bn (£1.84bn).
