The answer is P3,385,000. I just need the complete solution.

White Co. purchased four convenience store buildings on January 1, 2003 for a total of P22300900. The buildings have been depreciated using the straight-line method with a 20-year useful life and 5% residual value. As of January 1' 2010, White Co. has converted the buildings into Internet Learning Centers. Because of the change in the use of the buildings, White is evaluating the buildings for possible impairment. White estimates that the buildings have a remaining useful life of 10 years and that their residual value will be zero and net cash inflow from each building will be P500,000 per year and appropriate discount rate that reflects current market assessments of time value of money is 12%. Present value of annuity for the discount rate for 10 periods is 5.65. The fair value less cost to sell of the four buildings is not clearly determinable. What amount of impairment loss. if any. should be recognized
