キャッシュ・フロー
The value test for potential inclusion in the B400 takes into consideration a company's capital structure, price-to-book, price-to-cash-flow and price-to-sales ratios; overall market capitalization and price/earnings measures. Profitability is determined by a combination of asset and capital use, operating margins, relative margins, return on equity and quality of revenues. Cash flow is analyzed from cash flow growth, cash flow margin, debt-to-cash-flow ratio; interest coverage capacity, economic value and cash-retention rate.
