Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America have been condensed or omitted pursuant to such rules and regulations; however, we believe that the footnotes adequately disclose the information presented. These condensed financial statements should be read in conjunction with the financial statements and the notes thereto, included in our 2013 Annual Report on Form 10-K filed with the SEC. | |
Accounting methods historically employed require certain estimates as of interim dates.

The results of operations for the three months ended March 31, 2014 and March 31, 2013, and our financial condition as of March 31, 2014 and December 31, 2013 are not necessarily indicative of the results of operations and financial condition to be expected as of or for any other period. | |

We have entered into a Utility Money Pool Agreement (the “Agreement”) with BHC, Cheyenne Light and Black Hills Energy. Under the Agreement, we may borrow from BHC; however the Agreement restricts us from loaning funds to BHC or to any of BHC’s non-utility subsidiaries. The Agreement does not restrict us from paying dividends to BHC. Borrowings and advances under the Agreement bear interest at the weighted average daily cost of our parent company’s credit facility borrowings as defined under the Agreement, or if there are no external funds outstanding on that date, then the rate will be the daily one-month LIBOR plus 1.0%. At March 31, 2014, the cost of borrowing under the Utility Money Pool was 1.61%. | ||||||||

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Accounting guidance on fair value measurements establishes a hierarchy for grouping assets and liabilities, based on significance of inputs.

COMMITMENTS AND CONTINGENCIES | |
Other than the items discussed below, there have been no significant changes to commitments and contingencies from those previously disclosed in Note 11 of our Notes to the Financial Statements in our 2013 Annual Report on Form 10-K. | |
Cheyenne Prairie | |
Construction is continuing on Cheyenne Prairie, a natural gas-fired electric generating facility, jointly owned by us and Cheyenne Light. We own 55 MW and Cheyenne Light owns 40 MW of the facility’s combined-cycle unit. We expect to incur approximately $96 million of the expected total cost for our share of the jointly owned combined-cycle unit. Year-to-date expenditures for construction costs for our share of the combined cycle unit are approximately $13 million. Construction is expected to be completed by September 30, 2014. As of March 31, 2014, committed contracts for equipment purchases and for construction were 100% and 83% complete, respectively. | |
Oil Creek Fire | |
On June 29, 2012, a forest and grassland fire occurred in the western Black Hills of Wyoming. A state fire investigator concluded that the fire was caused by the failure of a transmission structure owned, operated and maintained by Black Hills Power. On April 16, 2013, a lawsuit was filed in the United States District Court for the District of Wyoming, which forty-seven plaintiffs have now joined, asserting claims for damages against Black Hills Power. The claims include allegations of negligence, negligence per se, common law nuisance, and trespass. Although not currently included in the lawsuit, Black Hills Power also received written damage claims from an additional landowner and from the State of Wyoming. Altogether the claims seek recovery for fire suppression, reclamation and rehabilitation costs, damage to fencing and other personal property, alleged injury to timber, grass or hay, livestock and related operations, and diminished value of real estate, for a current total amount of $16 million. In addition to claims for these compensatory damages, the lawsuit seeks recovery of punitive damages. Our investigation of the cause and origin of the fire is ongoing. We have denied and will vigorously defend all claims arising out of the fire, pending the completion of our investigation. We cannot predict the outcome of our investigation, the viability of alleged claims or the outcome of the litigation. | |
Civil litigation of this kind, however, is likely to lead to settlement negotiations, including negotiations prompted by pre-trial civil court procedures. We believe such negotiations would effect a settlement of all claims. Regardless of whether the litigation is determined at trial, or through settlement, we expect to incur significant investigation, legal and expert services expenses associated with the litigation. In order to limit our exposure to losses due to civil liability claims, and related litigation expense, we maintain insurance coverage above a $1.0 million deductible. We expect this coverage to limit our exposure, and we will pursue recoveries to the maximum extent available under the policies. Based upon information currently available, we believe that a loss associated with settlement of pending claims is probable. Accordingly, as of March 31, 2014, we recorded a loss contingency liability related to these claims, and we recorded a receivable for costs we believe are reimbursable and probable of recovery under our insurance coverage. Both of these entries reflect our reasonable estimate of probable future litigation expense and settlement costs; we did not base these contingencies on any determination that it is probable we would be found liable for these claims were they to be litigated. | |
Given the uncertainty of litigation, however, a loss related to the fire, the litigation and related claims, in excess of the loss we have determined to be probable is reasonably possible. However, we cannot reasonably estimate the amount of such possible loss because our investigation is ongoing, damage claims are currently incomplete or undocumented, and there are significant factual and legal issues to be resolved. Further claims may be presented by these and other parties. Based upon information currently available, however, management does not expect the outcome of the claims to have a material adverse effect upon our financial condition, results of operations or cash flows. |
