The cost of claims per cent, on wages paid amounted to £2 16s. 2d. for the year ended 31st March, 1950, as compared with £2 9s. 6d. for the previous year, while the average cost of each claim was £42 15s. 9d., as compared with £3O 13s. Bd. These increases reflect the increased benefits payable under the Workers' Compensation Amendment Act, 1949, which were payable from Ist September, 1949, and also the more serious nature of injuries with consequent longer periods on compensation. The Accident Insurance Working Account showed a surplus of £48,319 4s. lid. on the year's working, as compared with £51,474 2s. lOd. for the previous year, and the Accident Insurance Reserve Account now stands at £217,673
