## Q54 key (Merger Market With Missing Imports)

1. Industrial-yarn combined share is 20 percent. Premerger HHI is 12 squared + 8 squared + 25 squared + 20 squared + 15 squared + 10 squared + 10 squared = 1,658. Increase is 2 x 12 x 8 = 192; postmerger HHI is 1,850. Missed: the complete market screen is wrong.
2. Neither filing trigger applies in yarn: combined share is below 25 percent and HHI increase is not greater than 200. Post-HHI exceeds 1,800 but the delta fails the conjunctive trigger and presumption. Missed: one threshold component is treated as sufficient.
3. Medical-mesh combined share is $24 million divided by $80 million plus verified qualifying imports I. The share is at least 25 percent when 24/(80 + I) is at least 0.25. Solving gives I at or below $16 million. It falls below 25 percent only when imports exceed $16 million. Missed: management's vague import claim replaces the dispositive calculation.
4. Medical HHI cannot be computed because seller-by-seller import shares are absent. Total import revenue alone will not supply squared shares. Missed: a fabricated HHI is used for filing.
5. Obtain verified customer purchases, importer sales, product classifications, delivery destinations, and seller-level revenues within ten days. The customs category alone is insufficient. Missed: unrelated textiles dilute the market.
6. The filing call depends on the missing imports unless another reliable trigger emerges. Wait the ten days before closing, not before signing, and file if qualifying imports are $16 million or less or if uncertainty remains too great to establish below-threshold status. Missed: parties close on "probably" and incur $80,000 per day combined exposure.
7. Filing preserves legality without conceding competitive harm. Do not proceed to close without either verified data defeating both triggers or a filing and clearance. Missed: timing preference becomes gun jumping.
