The Chairman of FTSE 250 house builder Persimmon has purchased 10,000 ordinary shares one week after the firm accelerated its planned dividend payment strategy. Nicholas Wrigley, who bought the shares at an average price of 1,069p for a total of £106,900, now holds 36,000 shares in the company. The company's 10p-per-share dividend, previously planned for 2015, has been brought forward a year after shareholders agreed to the move at the most recent annual general meeting. Persimmon also last week said its weekly private sales per site were roughly 4.0% ahead of the previous comparable period. Its current total forward sales, including legal completions already achieved for the current year, stood at £1.38bn, 11% ahead of the prior year. Levels of enquiries were being aided by the new "Help to Buy" schemes announced in Chancellor George Osborne's recent budget, with website registrations up from 24% to 30% since the announcement, it added.
