(1) Effective rate includes the effect of the amortization of debt issuance costs. (2) NSM’s effective rate excludes the effect of the interest rate swap on the hedged portion of the debt. The weighted average interest rate for the quarter ended March 31, 2021 and December 31, 2020, excluding the effect of amortization of debt issuance costs, was 7.1% and 7.0%. The weighted average interest rate for the quarter ended March 31, 2021 and December 31, 2020 on the total NSM Bank Facility including both the effect of the amortization of debt issuance costs and the effect of the interest rate swap was 8.5% and 8.4%. Ark Subordinated Notes In March 2007, Ark issued $30.0 million face value of floating rate unsecured junior subordinated deferrable interest notes to Alesco Preferred Funding XII Ltd., Alesco Preferred Funding XIII Ltd. and Alesco Preferred Funding XIV Ltd (the “Ark Alesco Notes”) and a €12.0 million floating rate subordinated note to Dekania Europe CDO II plc (the “Ark Dekania Note”) (together, the “Ark Subordinated Notes”). The Alesco Notes, which mature in June 2037, accrue interest at a floating rate equal to the three-month U.S. LIBOR plus 4.6%. The Ark Dekania Note, which matures in June 2027, accrues interest at a floating rate equal to the three-month EURIBOR plus 4.6%. As of March 31, 2021, the Ark Alesco Notes had an outstanding balance of $30.0 million and the Ark Dekania Note had an outstanding balance of €12.0 million (approximately $14.1 million based upon the foreign exchange spot rate as of March 31, 2021). Ark Stand By Letter of Credit Facility Ark has a secured stand by letter of credit facility (the “Ark LOC Facility”) with three lenders, Lloyds Bank plc, National Westminster Bank plc and ING Bank N.V, London Branch to provide capital support for the Syndicates. As of March 31, 2021, the utilized level of the facility was $45.0 million, with the ability to increase to $150.0 million. The Ark LOC Facility has a termination date of December 31, 2025. During the three months ended March 31, 2021, Ark did not borrow or make any repayments under the Ark LOC Facility. The Ark LOC Facility, which provides funds at Lloyd’s, is secured by all property of the loan parties and contains various affirmative, negative and financial covenants that White Mountains considers to be customary for such borrowings, including a minimum tangible net worth covenant. NSM Bank Facility On April 7, 2020, NSM amended its secured credit facility (the “NSM Bank Facility”) with Ares Capital Corporation in connection with the acquisition of Kingsbridge. Under the amendment, the total commitment increased from $234.0 million, comprised of term loans of $224.0 million and a revolving credit loan of $10.0 million, to $291.4 million, comprised of term loans of $276.4 million, including £42.5 million (approximately $52.4 million based upon the foreign exchange spot rate as of the date of the transaction) in a GBP term loan, and a revolving credit loan commitment of $15.0 million. The term loans under the NSM Bank Facility mature on May 11, 2026, and the revolving loan matures on November 11, 2025. Under GAAP, if the terms of a debt instrument are amended, unless there is greater than 10% change in the expected discounted future cash flows of such instrument, the instrument’s carrying value does not change. White Mountains has determined that the impact of the changes to the terms of the NSM Bank Facility on the expected discounted future cash flows was less than 10%. Interest on the NSM Bank Facility accrues at a floating interest rate equal to the three-month LIBOR plus an applicable margin. In connection with the amendment, the reference rates for USD denominated borrowings increased. The USD-LIBOR rate floor increased to 1.25% and the margin over USD-LIBOR increased from a range of 4.25% to 4.75% to a range of 5.50% to 6.00%. For GBP denominated borrowings, the GBP-LIBOR rate floor is 1.25% and the margin over GBP-LIBOR ranges from 6.00% to 6.50%. The margins over the reference interest rates vary within the range depending on the consolidated total leverage ratio of NSM. The following table presents the change in debt under the NSM Bank Facility for the three months ended March 31, 2021 and 2020:
