Amber Devices Ltd. has total assets worth $900 million and total liabilities worth $475 million at the end of December 31. What is the amount of money received by the stockholders, if Amber liquidates all of its assets for $850 and pays off all of its outstanding debt at book value?

The current total assets of Amber devices are $900 million

IF they sell all their assets for 850 million they will have 850 million in cash. From this cash they have to pay their liabilities first, so

850 million - 475 million = 375 million

The book value of the liabilities was 475 million and because Amber devices pays of all its outstanding debt at book value, the remaining cash left for the stock holders is 375 million

The stock holder receive $375 million after liquidation of assets and payment of debt.
