In the balance sheet, in order to account for the money or amounts that go to an fro in the sheet, we use the equation,
NW = As - Li
where NW is the networth, As is the asset, and Li is liabilities.
From the given above, the total asset (As) is given to be $166.859M. The net worth is equal to the sum of the common stock, cash, and retained earnings.
Networth = ($5.080 M) + ($8.040 M) + ($36.411 M)
Networth = $49.531
The the equation above, we may derive the equation for liability by transposing,
Li = Asset - Networth
Li = ($166.859 M) - ($49.531 M)
Li = $117.328
Hence, the total liability is equal to $117.328.
