That number is as current as we have information on. However it only includes the reported bonuses which is Morales, Gonzalez, Torres, Aparicio, Tortolero, Muzziootti, and Mujica (or Pineda, or one of the Luiggis).
None of the other bonuses have been reported. By my count the Phillies have signed 30 other players during the international signing period, so even if they all got small bonuses (and it is likely a good chunk at least got in the $40,000 to $100,000 range) that adds up to a not insubstantial sum of money.
