The portfolios,
which are constructed at the end of each June, are allocated to two Size groups (Small and Big) using
NYSE median market cap breakpoint. Stocks in each Size group are allocated independently to four B/M groups
(low B/M to High B/M for fiscal year t-1) and four OP groups (Low OP to High OP for fiscal year t-1)
using NYSE quartile breakpoints specific to the Size group.
BE/ME for June of year t is the book equity for the last fiscal year end in t-1 divided by ME for December of t-1.
OP for June of year t is annual revenues minus cost of goods sold, interest expense, and selling, general, and administrative expenses
divided by book equity for the last fiscal year end in t-1. |

Please be aware that some of the value-weight averages of operating profitability for deciles 1 and 10 are extreme. These are driven by extraordinary values of OP for individual firms. We have spot checked the accounting data that produce the extraordinary values and all the numbers we examined accurately reflect the data in the firm's accounting statements.
