Let's approach this step-by-step:

1. First, we need to understand what each term means:

• Net exposure: The total risk exposure
• Collateral posted: The amount already provided as security
• Threshold amount: The exposure level below which no collateral is required
• Minimum transfer amount: The minimum amount of additional collateral that can be requested
• Rounding amount: The amount to round to when calculating collateral

2. Calculate the current situation:

• Current net exposure: $87,000,000
• Current collateral posted: $50,000,000
• Current additional collateral required = max(0, Net exposure - Threshold - Collateral posted)

= max(0, 87,000,000 - 65,000,000 - 50,000,000) = 0

3. Calculate the new situation:

• New net exposure: $110,000,000

• New additional collateral required = max(0, Net exposure - Threshold - Collateral posted)
  = max(0, 110,000,000 - 65,000,000 - 50,000,000) = $-5,000,000

4. The difference in collateral required:
   $-5,000,000 - 0 =$-5,000,000

5. Round to the nearest rounding amount ($10,000):
   $-5,000,000 rounded to nearest `$10`,000 = $-5,000,000

6. Check if this exceeds the minimum transfer amount:
   $|-5,000,000| = `$5,000,000, which is less than the minimum transfer amount of $12`,000,000

Therefore, despite the increase in net exposure, no additional collateral will be required from the hedge fund because the calculated amount doesn't meet the minimum transfer amount.
