$5,600

Explanation:

Jazz Corporation

Dividend $10,000

Less taxable income loss $2,000

Taxable income before the DRD$8,000

Thus:

70%×8,000

=$5,600

Therefore the amount of Jazz's dividends received deduction on the dividend it received from Williams Corp is $5,600 reason been that Jazz owns less than 20% of the Williams stock, the DRD percentage is 70%and $5,600 (70% × 8,000 taxable income before the DRD) is less than the full DRD of $7,000 and the full DRD due to the fact that it does not create a net operating loss ($8,000 - $7,000 = $1,000), so the DRD is limited to $5,600.
