Re:	Safety Insurance Group, Inc.
	Form 10‑K for the Fiscal Year Ended December 31, 2016
	Filed February 24, 2017
	File Number: 000‑50070

Dear Mr. Rosenberg:

Set forth below are the responses of Safety Insurance Group, Inc. (the “Company”) to comments from the staff (the “Staff) of the United States Securities and Exchange Commission (the “Commission”) received by letter dated May 5, 2017 concerning the Company’s Form 10‑K for the fiscal year ended December 31, 2016. We have used the information from our December 31, 2016 Annual Report on Form 10‑K for illustrative purposes in our responses below.

For your convenience, we have included the Staff’s comments in bold text in this letter and have included our response immediately after each comment. Page references refer to pages in the Company’s Form 10‑K for the Fiscal Year Ended December 31, 2016.

Notes to Consolidated Financial Statements

Note 10 - Loss and Loss Adjustment Expense Reserves, page 83

You disclose that private passenger and commercial automobile insurance covers physical damage to an insured’s vehicle as well as liabilities to third parties. Please tell us why you did not disaggregate liability from physical damage in the tables presenting incurred claims and cumulative paid claims for 2007 – 2016. Provide us the information that would be provided in the separate tables for liability and physical damage for both private passenger and commercial automobile insurance, if available.

Our private passenger automobile and commercial automobile insurance products provide coverage for bodily injury and property damage to others, no-fault personal injury coverage, and physical damage coverage for an insured’s own vehicle for collision or other perils. These coverages are typically sold together as one private passenger automobile insurance policy or one commercial automobile insurance policy depending on whether the vehicle is used for business purposes. In addition, when tracking the business, management does not view separately liability and physical

damage coverage, but instead views the business by product line of business as disclosed on pages 3‑4 of our Form 10‑K for the Fiscal Year Ended December 31, 2016.

Furthermore, Accounting Standards Codification (“ASC”) 944‑40‑55‑9B indicates that “When selecting the type of category to use to aggregate or disaggregate disclosures, an insurance entity should consider how information about the insurance entity’s liability for unpaid claims and claim adjustment expenses has been presented for other purposes, including all of the following:

Disclosures presented outside the financial statements (for example, in earnings releases, annual reports, statutory filings, or investor presentations)

Information regularly viewed by the chief operating decision maker for evaluating performance

Other information that is similar to the types of information identified in (a) and (b) and that is used by the insurance entity or users of the insurance entity’s financial statements to evaluate the insurance entity’s financial performance or make resource allocation decisions.”

On pages 50‑58 of our Form 10‑K for the Fiscal Year Ended December 31, 2016, we discuss our loss and loss adjustment expense reserves by line of business, consistent with how management views the business. This includes disclosures of private passenger automobile and commercial automobile loss and loss adjustment expense reserves which are not disaggregated into liability and physical damage components.

Additionally, ASC 944‑40‑50‑4H requires an insurance entity to aggregate or disaggregate certain disclosures 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 to allow users to understand the amount, timing, and uncertainty of cash flows arising from contracts issued by insurance entities. Consequently, the extent to which an insurance entity’s information is aggregated or disaggregated for the purposes of those disclosures depends on the facts and circumstances that pertain to the characteristics of the liability for unpaid claims and claim adjustment expenses. Our reserves for private passenger automobile and commercial automobile physical damage are relatively immaterial to the overall reserve balances as included below. Management’s view considers that there is no additional significant information to be obtained from further disaggregation.

The information for liability and physical damage for both private passenger and commercial automobile insurance are presented separately in the tables below and dollar amounts are presented in thousands.
