Any statements that do not relate to historical or current facts or matters are forward-looking statements. You can identify some of the forward-looking statements by the use of forward-looking words, such as &#8220;intend" and the like, or the use of future tense.  Statements concerning current conditions may also be forward-looking if they imply a continuation of current conditions. Examples of forward-looking statements include, but are not limited to, statements concerning the additional steps that we intend to take to mitigate the risk that our necessary 3TG finance or benefit armed groups.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">Forward-looking statements are subject to risks and uncertainties that could cause actual actions or performance to differ materially from those expressed in the forward-looking statements. These risks and uncertainties include, but are not limited to, (1) the continued implementation of satisfactory traceability and other compliance measures by our direct and indirect suppliers on a timely basis or at all and (2) political and regulatory developments, whether in the Democratic Republic of the Congo ("DRC") region, the United States or elsewhere. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of filing of this document. We do not intend, and undertake no obligation, to publish revised forward-looking statements to reflect events or circumstances after the date of filing of this document or to reflect the occurrence of unanticipated events.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-weight:bold;">Limited Applicability of the Conflict Minerals Rule to Our Company; Our Responsible Sourcing Commitment</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">We are a diverse financial holding company serving a variety of niche markets. Our principal business markets and underwrites specialty insurance products.  Therefore, a significant portion of our business activities do not involve manufacturing or contracting to manufacture products that contain 3TG.  Through our wholly-owned subsidiary Markel Ventures, Inc. ("Markel Ventures"), we own controlling interests in various industrial and service businesses that operate outside of the specialty insurance marketplace.  These controlling interests include interests in a diverse portfolio of industrial and service companies from various industries, including manufacturers of (1) dredging equipment, (2) high-speed bakery equipment, and (3) laminated furniture products.  </font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">We are subject to the Conflict Minerals Rule because some products manufactured by the foregoing businesses contain 3TG that are necessary to the functionality or production of the manufactured products. However, we are not a significant user of 3TG.  We strongly disapprove of the violence in the DRC and adjoining countries and are committed to understanding our supply chain of 3TG.   Markel is also </font></div><div><br></div><div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">committed to exercising due diligence on the source and chain of custody of any 3TG that conforms to a nationally or internationally recognized framework, and we take seriously our compliance obligations under the Conflict Minerals Rule.  We do not seek to embargo the sourcing of 3TG from the DRC region.</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">We do not directly source 3TG from mines, smelters or refiners, and we believe that we are in most cases many levels removed from these market participants.  However, through the efforts described in this Conflict Minerals Report, we seek to ensure that our sourcing practices are consistent with our position on 3TG sourcing discussed above.</font></div><div style="line-height:120%;padding-bottom:13px;padding-top:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-weight:bold;">Reasonable Country of Origin Inquiry Information</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">As required by the Conflict Minerals Rule, for 2015, we conducted a "reasonable country of origin inquiry."  For our reasonable country of origin inquiry, to the extent applicable, we utilized the same processes and procedures as for our due diligence, in particular Steps 1 and 2 of the OECD Guidance (as defined below).</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">Our outreach included approximately 300 suppliers (the "Suppliers") that we identified as having provided us, or that we believe may have provided us, with components, parts or ingredients that contain 3TG that are necessary to the functionality or production of our products.  We determined which of our products were potentially in-scope for purposes of the Conflict Minerals Rule through product specifications, visual inspection, supplier inquiries and other information known to us.  </font></div><div style="line-height:120%;padding-bottom:13px;padding-top:16px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">Pursuant to the Conflict Minerals Rule, based on the results of our reasonable country of origin inquiry, we were required to conduct due diligence for 2015.

Markel has internal operating processes for all departments and business units that are affected by 3TG. The processes involve the identification of in-scope products and suppliers of those products, communication with and inquiries made of the suppliers and reporting the results of supplier communication and inquiries to certain members of senior leadership.  Markel has an internal team charged with compliance with the Conflict Minerals Rule including operations personnel at each of the affected locations, accounting, legal and management personnel.  This team is responsible for collecting and reviewing information from suppliers and preparing our filing. </font></div></td></tr></table><div style="line-height:120%;text-align:left;padding-left:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;"><br></font></div><div><br></div><div><div style="line-height:120%;text-align:center;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">2</font></div></div><hr style="page-break-after:always"><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><div><br></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:12pt;padding-left:24px;"><font style="font-family:inherit;font-size:12pt;">2.</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;text-decoration:underline;">Risk Assessment &amp; Risk Mitigation</font><font style="font-family:inherit;font-size:12pt;">.  As part of Markel&#8217;s internal operating processes relating to 3TG compliance, our separate divisions with potentially in-scope products handle relationships with suppliers on an individual basis given the different types of products they manufacture.  Suppliers for one of our divisions are required to acknowledge a requirement to cooperate in our 3TG reporting, and suppliers in another division are provided with a statement on 3TG reporting encouraging awareness of and compliance with the requirements.  In addition, we have developed standard forms across all divisions for contacting suppliers that ask the third parties to confirm whether their applicable parts, materials or components contain 3TG, and, if so, the origin of such 3TG.   Responses to these inquiries are reviewed and retained for at least five (5) years as part of our internal operating procedures.  In certain cases, Markel follows up with suppliers who do not initially provide sufficient information.  Our divisions address identified risks on a case-by-case basis.  This flexible approach enables us to tailor the response to the risks identified.  Markel relies on its existing alertline as a grievance mechanism for any issues identified in the supply chain by participants in this process or other stakeholders.   </font></div></td></tr></table><div style="line-height:120%;text-align:left;padding-left:48px;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;"><br></font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;font-weight:bold;">Due Diligence Program Execution</font></div><div style="line-height:120%;padding-bottom:13px;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">In furtherance of our 3TG due diligence, we performed the following due diligence measures in respect of the 2015 compliance period:  </font></div><table cellpadding="0" cellspacing="0" style="font-family:Times New Roman; font-size:10pt;"><tr><td style="width:48px;"></td><td></td></tr><tr><td style="vertical-align:top"><div style="line-height:120%;font-size:12pt;padding-left:24px;"><font style="font-family:inherit;font-size:12pt;">1.</font></div></td><td style="vertical-align:top;"><div style="line-height:120%;text-align:justify;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">We sent requests to Suppliers to provide us with information, through the completion of our questionnaire, concerning the potential usage and source of 3TG in the parts, materials or components that they sell to us, as well as information concerning their related compliance efforts.
