This letter is in response to the Division of Corporation Finance’s comment letter dated November 17, 2017, in which you requested additional information based on your review of the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (the “2016 10-K”). For ease of reference, the comment included in your letter is repeated below in italicized type, and our response immediately follows the comment.

Please provide us an analysis of each of the business divisions (i.e. excess casualty, primary casualty, environmental and other P&C) within your U.S. Insurance – U.S. P&C operating segment to help us evaluate whether further disaggregation of the incurred and paid claims tables on page F-26 for this operating segment is necessary. We are concerned that the information for this operating segment in the tables is obscured by the aggregation of items with significantly different characteristics. Refer to ASC 944-40-50-4H. In your analysis, compare and contrast the characteristics of the business divisions as well as comparing and contrasting the characteristics of products within each division. In various places in your filing, you refer to short tail and long tail classes of business. To further help us with our evaluation, please provide us tables that aggregate the short tail classes of business separately from your long tail classes of business for your U.S. Insurance – U.S. P&C operating segment.

ASC 944-40-50-4H requires aggregation or disaggregation of the disclosures outlined in paragraphs 944-40-50-4B through 50-4G and 944-40-50-5, which includes the incurred and paid tables, in a manner that allows the users to understand the amount, timing and uncertainty of cash flows arising from the liability for unpaid claims and claims adjustment expenses. The guidance goes on to state that an insurance entity should aggregate or disaggregate so that useful information is not obscured by either the inclusion of a large amount of insignificant detail or the aggregation of items that have significantly different characteristics.

Paragraph 944-40-55-9B explains that when selecting the type of category to use for aggregating or disaggregating disclosures, an insurance entity should consider how information about the entity’s liability for unpaid claims and claims adjustment expenses has been presented for other purposes, including:

Paragraph 944-40-55-9C provides examples of categories that might be appropriate including:

When applying the guidance, an insurance entity should not aggregate amounts from different reportable segments.

We applied the above guidance when analyzing and preparing our disclosures for the 2016 10-K.

When drafting the 2016 10-K, the Company held extensive internal discussions specifically to determine the most meaningful aggregation or disaggregation of our business appropriate for the short-duration contract disclosures. We concluded that the presentation in Note 5 of the 2016 10-K, including the U.S. Insurance P&C operating segment, would provide an appropriate level of information that would be meaningful to the users of the financial statements to better understand the amount, timing, and uncertainty of cash flows arising from our liability for unpaid claims and claims adjustment expenses.

Specifically, the U.S. Insurance P&C operating segment is comprised of our excess casualty, primary casualty, environmental and other P&C divisions. Details as regards each of these divisions are as follows:

Primary Casualty business is comprised of General Liability coverage, which is long tail in nature, provided principally through wholesale insurance brokers for specialty risks, a large segment of which is construction related risks. The Company has retained net limits on Primary Casualty of up to $2 Million on each account.

Excess Casualty business is comprised of General Liability coverage, which is long tail in nature, provided principally through wholesale insurance brokers for specialty risks, a large segment of which is construction related risks. The Company retains $7 Million or less on seventy five percent of the accounts, with a maximum net retention of $10 Million per account.

Environmental business is principally comprised of General Liability and Professional Liability coverages, which are long tail in nature, provided to businesses with environmental exposures (such as contractors, engineers and manufacturers) provided principally through wholesale insurance brokers. The Company retains up to $5 Million on each account.

Other P&C business is comprised of a variety of the Company’s lower volume Active and Runoff products, including Excess and Surplus Property, Commercial Auto and Surety, which are long tail and short tail in nature, in the Active line.

While each division within our U.S. Insurance P&C operating segment is distinct, only one has sufficient volume to provide material information regarding the behavior of unpaid claims on its own. The chart below shows a comparison of open claims from the divisions within the U.S. Insurance P&C operating segment as of year-end 2016.

Count of Open Claims	2007		2008		2009		2010		2011		2012		2013		2014		2015		2016		Total

Total		575		364		260		364		472		553		589		808		1,202		1,467		6,654
Primary Casualty		561		330		234		316		412		468		432		631		836		884		5,104	77	%
Excess Casualty		6		11		11		17		25		53		86		86		97		77		469	7	%
Environmental		0		0		0		1		12		15		21		30		60		78		217	3	%
Other - Active		0		0		0		3		3		3		20		32		206		427		694	10	%
- Runoff		8		23		15		27		20		14		30		29		3		1		170	3	%

As such, the data underlying the outstanding reserves is dominated by the Primary Casualty division. Applying the commonly used actuarial standard for full data credibility, which requires a minimum of 1,082 claims¹, only the Primary Casualty division exceeds the standard and will produce consistent and indicative data to assist the user to better understand the liability. Even if the number of open claims for the remaining divisions were to meet such minimum standard noted above, that alone would not necessarily require further disaggregation of the data as it would still need to prove meaningful. Nonetheless, the number of open claims for the remaining divisions fall well below such standard and would not be meaningful on their own. Additionally, the inclusion of this data both individually and in the aggregate within the total operating segment tables would not impact the usefulness or meaningfulness of the data for users of the financial statements, including the identification of material trends.

An excellent example of the reason for applying the minimum requirements for full data credibility can be seen in the disaggregation of our long tail classes of business from our short tail classes of business. The attached exhibit includes the tables illustrating such disaggregation, which the staff requested. As you can see, the short tailed business makes up an immaterial component of the overall operating segment and does not provide meaningful information to users of the financial statements.

Some of our divisions have the potential to grow and may reach the point where additional disaggregation of the data will be useful and meaningful to the users of the financial statements. We will continue to monitor the relevance of the data available to assess our determination of the most appropriate level of disaggregation for purposes of the short-duration contract disclosures.

Based on our interpretation of the accounting guidance and our analysis of the underlying characteristics of the divisions and products as provided above, we have concluded that the level of disaggregation for the Company’s net incurred and paid loss and loss expense development tables in the 2016 10-K is appropriate and meets the requirements of ASC 944-40-50-4H, and further disaggregation is not meaningful at this time. The Company will continually monitor our disclosure requirements as our business develops and changes over time. If the facts and circumstances warrant it, further disaggregation will be applied.

We welcome the opportunity to discuss any of the information included herein should you desire. If you have any questions or comments concerning this response letter, please contact the undersigned at (203) 905-6343 (cdefalco@navg.com) or Emily Miner at (203) 905-6369 (eminer@navg.com).
