Nan Ya Plastics ROC (Joel Greenblatt) % Calculation
Joel Greenblatt defined Return on Capital differently in his book The Little Book That Still Beats the Market (Little Books. Big Profits) . He defines Return on Capital as follows:
EBIT stands for Earnings Before Interest and Taxes.
Fixed Assets are also known as non-current assets. They include the Property, Plant and Equipment that the firm needs in its operation.
GuruFocus calculates net working capital as: (Accounts Receivable + Total Inventories + Other Current Assets) - (Accounts Payable & Accrued Expense + Deferred Revenue + Other Current Liabilities). We're trying to account for OPERATING assets and liabilities (part of daily business) when calculating working capital. Cash and marketable securities are considered NON-OPERATING assets and are not included in calculation. We will also back out all interest bearing debt, short term debt and the portion of long term debt that is due in the current period from the current liabilities. This debt will be considered when computing cost of capital and it would be inappropriate to count it twice.
Note:
The EBIT data used here is four times the quarterly (Dec. 2025) EBIT data.
