Entertainment One CEO Darren Throop and Patrice Théroux, president of global filmed entertainment, have added to their stakes in the production/distribution company.

Both Throop and Théroux paid $122,500 for 300,000 shares in E1 at 21.5 pence each after the company last week released its full-year 2009 results on an upbeat note.

More significantly, E1 CFO Giles Willits also purchased 300,000 shares at 21.5 pence (41 cents) each to take his interest in the Toronto-based company to 320,000 shares, or a 0.25% stake. E1 trades on London’s AIM Exchange.

Share purchases by a CFO, the senior executive who presumably best knows a company’s financial health, generally signals a vote of confidence in its corporate future.

The latest insider purchases at E1 take Throop’s stake to 3.47 million shares. Theroux, who also bought another 37,000 shares at 24.2 pence (46 cents) each, now owns a 0.33% stake.

E1’s other big shareholders include British equity investor Marwyn Neptune Fund with a 44.4% stake, and Toronto indie film producer Robert Lantos with a 1.75% holding.
