$\begin{array}{|l|l|}\hline \text { Cash and Short-Term Securities } & \$ 200,000 \\\hline \text { Inventory } & \$ 90,000 \\\hline \text { Plant and Equipment (net) } & \$ 250,000 \\\hline \text { Current Liabilities } & \$ 160,000 \\\hline \text { Bonds Pay able } & \$ 88,000 \\\hline\end{array}$ In addition to the above, an independent appraiser deemed that DEF456 Inc. had trademarks with a fair market value of $100,000 which had not been accounted for. In turn, ABC123's fair market values were equal to their book values with the exception of the Company's Inventory and Plant and Equipment, which were said to have Fair Market Values of $30,000 and $480,000, respectively.
Assuming that DEF456's Plant and Equipment was worth $400,000. Calculate the goodwill arising from this business combination and state how it would be shown in the consolidated balance sheet on the acquisition date.
