“The change in fair value of FG VIEs’ assets and liabilities where the FVO was elected is reported in “fair value gains (losses) on FG VIEs” in the consolidated statements of operations, except for the change in fair value attributable to change in instrument-specific credit risk (ISCR) on FG VIEs’ liabilities for which the FVO was elected, which is reported in “other comprehensive income” Interest income and interest expense are derived from the trustee reports and also included in “fair value gains (losses) on FG VIEs.” For those FG VIE liabilities with recourse to the Company, the portion of the inception-to-date change in fair value, attributable to ISCR, is calculated by holding all current period assumptions constant for each security and isolating the effect of the change in AG’s CDS spread from the most recent date of consolidation to the current period.”
