Listed investment company Brickworks Investment has managed to eke out a 6.2 per cent rise in net profit after tax of $14.2 million for the half-year ended December 31. In the volatile and difficult investment climate, operating revenue grew 5.4 per cent to $11.1 million. The increased share capital has allowed the company to maintain a fully franked 3¢ per share interim dividend and Brickworks will also be maintaining its dividend reinvestment plan. Brickworks is keeping quite a high cash ratio of 13 per cent of total assets, or $55.9 million in cash. During the first half of financial year 2009, Brickworks acquired Huntley Investment Corporation. Consolidated profit for the half-year results includes a $4.1 million gain recognised from the discount on acquisition of the Huntley business.
