Part III stipulations
Column (c)
- If Line 10 is $0, column (c) is not completed.
- If Line 10 is greater than Lines 47(a) + 47(b), the amounts entered in column (c) equal sum of the amounts in columns (a) and (b) on the same line .
- If Line 10 is greater than $0 but less than the total of Lines 47(a) + 47(b), the Line 10 amount represents the allowable loss and it is pro-rated in column (c) with any loss amounts found on Lines 35 through 46 in columns (a) and (b).
Column (d)
- If the Line 29 Total is $0, this column is skipped.
- If Line 10 is greater than Line 47(c), this column is skipped. (In other words, stock basis is more than the total allowable loss from stock basis, so stock basis is still greater than $0.)
- If the Line 29 Total is greater than Lines 47(a) + 47(b) – 47(c), column (d) equals the sum of column (a) + (b) – (c) on the same line. (At this point, stock basis is $0 but debt basis is greater than the remaining allowable loss, so the full loss is allowed.)
- If the Line 29 Total is greater than $0 but less than Lines 47(a) + 47(b) – 47(c), the Line 29 Total represents the remaining allowable loss and it is pro-rated in column (d) with any loss amounts found on Lines 35 through 46 in columns (a) and (b). (If there is a carryover, both stock basis and debt basis are $0.)
