Think mortgage math is complicated? Many in the nation are focused on air conditioning. Why is it measured in tons? It harkens back to the days of using ice, and a “ton” measures how much heat, removed by the system, would be needed to melt 2,000 pounds, or one ton, of ice in a 24-hour period. The result is then expressed in BTUs per hour. It takes 288,000 BTUs to melt a ton of ice in 24 hours, or 12,000 BTUs per hour. 1 BTU/hr. = 0.00029307107 kWh. And the average residential electricity rate in the U.S. is about 23 cents per kilowatt-hour (kWh). When you see your utility bill in the mail, don’t think about me. Maybe the math in a company acquisition is more straightforward. I mention this since ICE and Black Knight have agreed to sell Optimal Blue to Constellation Software in an effort to get regulatory approval for their merger. Constellation Software is already buying Empower and will purchase OB for $700 million paid for in $200 MM cash and a $500MM promissory
