Derivative Instruments and Hedging Activities Disclosure [Abstract] |
Derivatives | Derivatives HG Global Interest Rate Cap On June 16, 2022, HG entered into an interest rate cap agreement, effective on July 25, 2022, to limit its exposure to the risk of interest rate increases on the HG Global Senior Notes. The notional amount of the interest rate cap is $150.0 million and the termination date is July 25, 2025. HG paid initial premiums of $3.3 million for the interest rate cap. Under the terms of the interest rate cap agreement, if the current three-month SOFR rate at the measurement date exceeds 3.5%, HG will receive payments from the counterparty equal to the difference between the three-month SOFR rate on the determination date and 3.5%, multiplied by the notional amount of the cap based on the number of days in the quarter and a year equal to 360 days. As of September 30, 2022, the three-month SOFR rate was 3.6%. HG accounts for the interest rate cap as a derivative at fair value, with changes in fair value recognized in current period earnings within interest expense. For the three and nine months ended September 30, 2022, White Mountains recognized a gain of $2.1 million and $0.6 million related to the change in fair value on the interest rate cap within interest expense. As of September 30, 2022, the estimated fair value of the interest rate cap recorded in other assets was $3.9 million. White Mountains classifies the interest rate cap as a Level 2 measurement.
