DNAD includes $3,500,000 as an intangible asset representing what they paid for Apache Mobile. This is akin to goodwill and does not contribute to book value.
Actual book value is:
Tangible assets: cash of 2,494 + investment loans of 32,280 = 34,774
Liabilities: current liabilies of 38,120 + non current liabilities of 30,000 = 68,120
