In Studying the Impact of Consolidation on Price/Earnings (P/E) Ratios $\bullet$

In studying the impact of consolidation on Price/Earnings (P/E) ratios, there are four basic methods of consolidating the account of a subsidiary into the parent company:
$\bullet$ Full consolidation. Assets, liabilities, and earnings of the subsidiaries are fully incorporated,
line-by-line, into the parent's accounts, with special care to avoid double counting.
$\bullet$ Proportional consolidation. Assets, liabilities, and earnings are consolidated line-by-line, proportionate to the percentage of ownership in the subsidiary.
$\bullet$ Equity consolidation. A share of the subsidiary profits is consolidated on a one-line basis, proportionate to the share of equity owned by the parent. The value of the investment in the subsidiary is adjusted to reflect the change in the subsidiary's equity.
$\bullet$ No consolidation. This is sometimes referred to as the cost method, whereby only dividends received from the subsidiary affect earnings of the parent. The value of the investment in the subsidiary is carried at cost in the parent's book and is not revalued.
Here are the simplified 2000 accounts of Papa SA and Fille SA, two French firms. Papa SA owns 50% of Fille SA, a company created the previous year. Fille SA has not paid any dividend. The nonconsolidated accounts follow:
$$\begin{array} { l c c } & \begin{array} { c } \text { Papa SA } \\\text { E million }\end{array} & \begin{array} { c } \text { Fille SA } \\\text { E million }\end{array} \\\hline \text { Falance Sheets, End-2000 } & & \\\text { Fixed Assets } & 400 & \text { 80 } \\\text { Investment in Subsidiary } & 50 & \\\text { Current Assets } & \underline {50 }& \underline { 40 } \\\text { Total Assets } & 500 & 120 \\\text { Share Capital } & 440 & 100 \\\text { Net Income 2000 } & \underline {60} &\underline { 20} \\\hline\end{array}$$ Continued
$\begin{array}{c}\begin{array}{lll}\\\\ \hline \text { Stockholders Equity }\\ \text { Minority Interests}\\ \text { Total Liabilities}\\ \text { Income Statement 2000}\\ \text { Revenues}\\ \text { Expenses}\\\\ \text { Income from Subsidiary}\\ \text { Minority Interests (-)}\\ \text { Net Income}\end{array}\begin{array}{lll} \text {Papa SA}\\ \text { € million}\\ \hline 500\\--\\500\\\\300\\\underline{240}\\60\\\\--\\60\end{array}\begin{array}{lll} \text {Fille SA}\\ \text { € million}\\ \hline 120\\--\\120\\\\80\\\underline{60}\\20\\\\--\\20\end{array}\end{array}$
The nonconsolidated accounts for Papa SA use the cost method, whereby the investment in the subsidiary is carried at historical cost in the balance sheet of the parent.
