• other hazards that could also result in personal injury and loss of life, pollution and suspension of operations. Any of these risks could adversely affect our ability to conduct operations or result in substantial loss to us as a result of claims for: • • • • • • • personal injury or loss of life; damage to and destruction of property, natural resources and equipment, including our coal properties and our coal production or transportation facilities; pollution and other environmental damage to our properties or the properties of others; potential legal liability and monetary losses; regulatory investigations and penalties; suspension of our operations; and repair and remediation costs. In addition, the total cost of coal sold and overall coal production may be adversely affected by various factors. For example, unit costs were negatively impacted in 2014 due to adverse geological conditions at the Enlow Fork Mine, primarily related to sandstone intrusions, along with adverse geological conditions and equipment issues at the Harvey Mine, primarily related to sandstone intrusions, which resulted in reduced coal production at both the Enlow Fork and Harvey Mines. Although we maintain insurance for a number of risks and hazards, we may not be insured or fully insured against the losses or liabilities that could arise from a significant accident in our coal operations. We may elect not to obtain insurance for any or all of these risks if we believe that the cost of available insurance is excessive relative to the risks presented. In addition, pollution and environmental risks generally are not fully insurable. Moreover, a significant mine accident could potentially cause a mine shutdown. The occurrence of an event that is not fully covered by insurance could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to make cash distributions. In addition, if any of the foregoing changes, conditions or events occurs and is not excusable as a force majeure event, any resulting failure on our part to deliver coal to the purchaser under our contracts could result in economic penalties, suspension or cancellation of shipments or ultimately termination of the agreement, any of which could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to make cash distributions. All of our mines are part of a single mining complex and are exclusively located in the Northern Appalachian Basin, making us vulnerable to risks associated with operating in a single geographic area. All of our operations are conducted at a single mining complex located in the Northern Appalachian Basin in southwestern Pennsylvania. The geographic concentration of our operations at the Pennsylvania mining complex may disproportionately expose us to disruptions in our operations if the region experiences severe weather, transportation capacity constraints, constraints on the availability of required equipment, facilities, personnel or services, significant governmental regulation or natural disasters. If any of these factors were to impact the Northern Appalachian Basin more than other coal producing regions, our business, financial condition, results of operations and ability to make cash distributions will be adversely affected relative to other mining companies that have a more geographically diversified asset portfolio. The availability and reliability of transportation facilities and fluctuations in transportation costs could affect the demand for our coal or impair our ability to supply coal to our customers. Transportation logistics play an important role in allowing us to supply coal to our customers. Any significant delays, interruptions or other limitations on the ability to transport our coal could negatively affect our operations. Currently, all of our coal is transported from the Pennsylvania mining complex by rail. Delays and interruptions of rail services because of accidents, infrastructure damage, lack of rail or port capacity, weather related problems, governmental regulation, terrorism, strikes, lock-outs, third-party actions or other events could temporarily impair our ability to supply coal to customers and adversely affect our profitability. In addition, transportation costs represent a significant portion of the delivered cost of coal and, as a result, the cost of delivery is a critical factor in a customer’s purchasing decision. Increases in transportation costs, including increases resulting from emission control requirements and fluctuations in the price of locomotive diesel fuel and demurrage, could make our coal less competitive, which could have a material adverse effect on our business, financial condition, results of operations, cash flows and ability to make cash distributions. 20
