Non-GAAP Financial Measures Reconciliation

We present our results of operations in a way that we believe will be the most meaningful and useful to investors, analysts, rating agencies and others who use our financial information to evaluate our performance. Some of the measurements are considered non-GAAP financial measures under SEC rules and regulations. In this press release, we present underwriting income (loss), a non-GAAP financial measure as defined in Item 10(e) of SEC Regulation S-K. We believe that non-GAAP financial measures, which may be defined and calculated differently by other companies, help explain and enhance the understanding of our results of operations. However, these measures should not be viewed as a substitute for those determined in accordance with U.S. GAAP. Where appropriate, reconciliations of our non-GAAP measures to the most comparable GAAP figures are included below.

Underwriting Income (Loss)

We calculate underwriting income (loss) on a pre-tax basis as net premiums earned less losses and loss adjustment expenses, acquisition costs and other underwriting expenses (net of third party fee income). We believe that this measure of our performance focuses on the core fundamental performance of the Company’s reportable segments in any given period and is not distorted by investment market conditions, corporate expense allocations or income tax effects.

The following table reconciles underwriting income (loss) to net income (loss), the most comparable GAAP financial measure:

Third Party Fee Income

Third party fee income includes income that is incremental and/or directly attributable to our underwriting operations. It is primarily comprised of fees earned by the International Segment for management services provided to third party syndicates and consortia and by the Bermuda Segment for performance based management fees generated by our third party capital manager, Ada Capital Management Limited. We believe that this measure is a relevant component of our underwriting income (loss).

The following table reconciles third party fee income to other income, the most comparable GAAP financial measure:

	For the Three Months Ended				For the Years Ended
($ in thousands)	December 31, 2023		December 31, 2022		December 31, 2023		December 31, 2022
Third party fee income	$	10,480	$	2,254	$	18,234	$	11,631
Other income (loss), excluding third party fee income	312		(55)		397		(315)
Other income (loss)	$	10,792	$	2,199	$	18,631	$	11,316

Other Underwriting Expenses

Other underwriting expenses include those general and administrative expenses that are incremental and/or directly attributable to our underwriting operations. While this measure is presented in Note 10, Segment Reporting in the consolidated financial statements, it is considered a non-GAAP financial measure when presented elsewhere.

Corporate expenses include holding company costs necessary to support our reportable segments. As these costs are not incremental and/or directly attributable to our underwriting operations, these costs are excluded from other underwriting expenses, and therefore, underwriting income (loss). General and administrative expenses, the most comparable GAAP financial measure to other underwriting expenses, also includes corporate expenses.

The following table reconciles other underwriting expenses to general and administrative expenses, the most comparable GAAP financial measure:

	For the Three Months Ended				For the Years Ended
($ in thousands)	December 31, 2023		December 31, 2022		December 31, 2023		December 31, 2022
Other underwriting expenses	$	56,923	$	38,184	$	183,165	$	157,540
Corporate expenses	44,858		4,208		76,691		20,142
General and administrative expenses	$	101,781	$	42,392	$	259,856	$	177,682
