(a)	Classification within the fair value hierarchy

•	Level 1 - Fair values are measured based on unadjusted quoted prices in active markets for identical assets or liabilities that we have the ability to access.

•	Level 2 - Fair values are measured based on quoted prices in active markets for similar assets or liabilities, quoted prices for identical assets or liabilities in inactive markets, or for which significant inputs are observable (e.g. interest rates, yield curves, prepayment speeds, default rates, loss severities, etc.) or can be corroborated by observable market data.

---

•	Level 3 - Fair values are measured based on inputs that are unobservable and significant to the overall fair value measurement. The unobservable inputs reflect our own judgments about assumptions where there is little, if any, market activity for that asset or liability that market participants might use.

(f)	During Q2 2013, the Company concluded that Cat 46, Cat 48 and Gryphon Alpha no longer remain eligible for potential allocations from the 2011 RDE.

---

(a)	During the year ended December 31, 2010, $19,242 was allocated to the Chilean earthquake and $16,614 was allocated to the New Zealand earthquake from the 2010 reserve for potential development on notable loss events.

(b)	Notable losses for the year ended December 31, 2010 included Chilean earthquake, Melbourne hailstorm, Windstorm Xynthia, Deepwater Horizon, Aban Pearl, Bangkok riots, Perth hailstorm, New Zealand earthquake, Oklahoma windstorm, Political risk loss, Hurricane Karl, Queensland floods, Political violence loss, Satellite failure and Financial institution loss.

(c)

Contract complexity, the nature and number of perils arising from these events, limits and sub limits exposed, the quality, flow and timing of information received by the Company, information regarding retrocessional covers, assumptions, both explicit and implicit, regarding future paid and reported loss development patterns, frequency and severity trends, claims settlement practices and potential changes in the legal environment continue to lead to complexity and volatility in the ultimate loss estimates for these events. Given the potential that one or some of the 2011 notable loss events eligible for potential allocation from the 2011 RDE may experience adverse development, rather than all deteriorating proportionately, an addition to the 2011 RDE of $27,926 was made during the year ended December 31, 2012.

(d)	The reserve for potential development on notable loss events (or “RDE”) is included as part of the Company's overall reserve requirement as defined and disclosed in the Critical Accounting Policies and Estimates section of the Company's Annual Report on Form 10-K/A.
