1. Booked value of intangible assets = 350 10 = 3.6 million yuan, monthly amortization = 360 ÷ 5 years ÷ 12 = 60,000 yuan;
2. Balance after amortization =360-6×27 months=360-162=1.98 million yuan;
3. Net loss=(198 150×5)-150=205.5-150=555,000 yuan;
4. Note: Additional taxes are not taken into account; in addition, the period from January 18, 2009 to April 16, 2011 is 27 months and 2 days, so it can only be amortized over 27 months.
