The amount of derisking required to meet the target and maximum metrics, relative to the starting NPO, was increased in 2022 compared to 2021 from 13% to 14% and from 15% to 17%, respectively. The ongoing challenge of de-risking exposures became even more challenging in 2022, which saw sharply higher interest rates, inflationary pressures, decreased municipal issuance, and diminished market liquidity that made refinancing transactions, restructurings, and commutations more difficult. Despite these challenges, as a result of management&#8217;s focused efforts, Ambac exceeded the maximum performance goal with year-end NPO reduced to $22.9 billion.

The 2022 targets recognized the challenges the Company faces to retain and incentivize qualified management and to manage expenses for a heavily regulated run-off insurance enterprise during an inflationary period. Specifically, inflation-driven increases in healthcare, insurance, audit, and other costs collectively outweighed meaningful 2022 budgeted cost reductions. In face of these challenges, management took decisive action to reduce headcount, including as a result of aggressive de-risking of the insured portfolio, resulting in the actual GORRE metric ($16.3 million) being lower than (i.e., better than) the maximum target metric ($16.5 million) for 2022.</font></div><div style="margin-bottom:9pt"><font style="color:#000000;font-family:'Times New Roman',sans-serif;font-size:12pt;font-weight:400;line-height:120%">While performance for NPO and GORRE earned above-target payouts, we note that management did not meet the targeted metric related to increasing gross written premium at Everspan.
