In response to your specific question per our telephone call, the pricing for subcontract work between the regions, including the work performed by the Intermountain region on jobs in the North Central region, is based on market prices assuming an arms-length transaction. The components are working together by utilizing the other regions to perform this subcontract work as opposed to hiring an external third party. Having these additional sources of labor and equipment has allowed certain regions to bid on more and larger jobs, which benefits the reporting unit.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">As indicated in MDU&#8217;s September 13, 2013, response letter, components of the construction materials and contracting reporting unit often transfer equipment between the regions throughout the year based on needs and to maximize equipment usage. For example, ready mix trucks were transferred from the Northwest region to the Intermountain region and a crusher was transferred from the South region to the Northwest region. To clarify our telephone conversation, both temporary and permanent transfers of equipment occur amongst the regions. On temporary transfers of equipment, rental rates are negotiated between the regions while permanent transfers of equipment occur at net book value. In response to your specific question per our telephone call, permanent equipment transfers have occurred between the construction materials and contracting operations located in Hawaii and Alaska (both of which are located in the Pacific region) and the other regions. For example, an excavator was transferred from the South region to our operations in Hawaii and a ready mix concrete plant was transferred from our operations in Alaska to the North Central region. In addition, intellectual resources and personnel are shared between Hawaii and Alaska and the other regions. For example, management, safety and accounting personnel have transferred from Hawaii and Alaska to other regions. Temporary sharing of intellectual resources and personnel also occurs between Hawaii and Alaska and the other regions to assist with various projects depending on specific jobs or circumstances and availability. As noted in our prior response, intellectual resources and personnel are shared between other regions. For example, management teams and individuals with expertise in operations, finance and accounting were brought into the South region from other regions in order to assist with improving operations and financial performance.</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:14pt;"><font style="font-family:inherit;font-size:14pt;text-decoration:underline;">Construction services reporting unit</font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">As indicated in MDU&#8217;s September 13, 2013, response letter, one of the components of the construction services reporting unit derived internal revenue from sales to the other components. In response to your question per our telephone call, this component provides equipment and supplies used by the outside electrical construction industry. The components of the construction services reporting unit that provide outside electrical construction services purchase and/or rent equipment and supplies from this component when it is feasible. Factors that affect the feasibility of purchasing and/or renting from this component include the availability of the equipment and supplies and the geographic location of the component which affects the cost of the equipment and supplies due to </font></div><br><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><hr style="page-break-after:always"><a name="s2e1a70cf58564d9cb4937a331ab08134"></a><div><div style="line-height:120%;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">MDU RESOURCES GROUP, INC.</font></div><div style="line-height:120%;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;"><br></font></div><div style="line-height:120%;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">Ms. Tia L.

However, even when the equipment and supply needs cannot be met by this component, the other components use the expertise of personnel at this component when purchasing equipment and supplies from third party vendors regarding quality and pricing. In summary, the outside electrical construction services components purchase and/or rent equipment and supplies from this component when feasible, rely on the expertise at this component when purchasing equipment and supplies from third party vendors, and this component provides products and services used by the electrical construction industry and its external customers are our peers in this industry as well. </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">As indicated in MDU&#8217;s September 13, 2013, response letter, while each component of the construction services reporting unit has its own operational management and crews, the components share resources in order to share expertise and improve operations which are dependent on specific jobs or circumstances and availability. Recent examples of this include employees at one component helping secure work for another component for solar projects, casinos and convention centers. The components also work together on the same projects and recent examples of this include casino, stadium and university projects. In response to your specific question per our telephone call, two components of the construction services reporting unit do perform work on the same contract with the customer that was discussed on the telephone. </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:14pt;"><font style="font-family:inherit;font-size:14pt;text-decoration:underline;">Summary of approach</font></div><div style="line-height:120%;text-align:left;text-indent:48px;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">While the above clarifies certain matters related to one of the factors used to determine whether two or more components should be aggregated and deemed a single reporting unit, there are numerous factors that are to be considered as discussed in more depth in our prior responses.  Unlike some accounting guidance where there are specific criteria that all need to be met to arrive at a certain conclusion, in this situation every factor need not be met in order for two components to be considered similar. Evaluating whether two components have similar economic characteristics is a matter of judgment that depends on specific facts and circumstances. That assessment should be more qualitative than quantitative. The accounting guidance also recognizes that a company that has a more diverse offering of products and services (such as MDU) may consider two products to be similar whereas a company that has a relatively narrow offering of products and services may not consider those same products to be similar. As described in paragraph 68 of the Basis for Conclusions of Statement 131, the assessment of whether products or services are similar may depend, in part, on the nature and breadth of a company's product lines and overall operations. </font></div><div style="line-height:120%;text-align:left;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div><div style="line-height:120%;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">The guidance in Statement 131 was a significant factor in our evaluation of whether to aggregate our components. MDU is a very diverse company with various lines of business including electric, natural gas distribution, pipeline and energy services, exploration and production of oil and natural gas, construction materials and contracting, and construction services. Each of these lines of business offers various products and services which we have described more fully in our previous responses </font></div><br><div><div style="line-height:120%;font-size:10pt;"><font style="font-family:inherit;font-size:10pt;"><br></font></div></div><hr style="page-break-after:always"><a name="s2e1a70cf58564d9cb4937a331ab08134"></a><div><div style="line-height:120%;text-align:left;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">MDU RESOURCES GROUP, INC.</font></div><div style="line-height:120%;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;"><br></font></div><div style="line-height:120%;font-size:12pt;"><font style="font-family:inherit;font-size:12pt;">Ms. Tia L.
