MANAGEMENT’S STATEMENT | |
The unaudited condensed financial statements included herein have been prepared by Black Hills Power, Inc. (the “Company,” “we,” “us,” or “our”), pursuant to the rules and regulations of the SEC. 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 2012 Annual Report on Form 10-K filed with the SEC. | |
Accounting methods historically employed require certain estimates as of interim dates. The information furnished in the accompanying condensed financial statements reflects all adjustments, including accruals, which are, in the opinion of management, necessary for a fair presentation of the September 30, 2013, December 31, 2012 and September 30, 2012 financial information and are of a normal recurring nature. The results of operations for the three months and nine months ended September 30, 2013 and September 30, 2012, and our financial condition as of September 30, 2013 and December 31, 2012 are not necessarily indicative of the results of operations and financial condition to be expected as of or for any other period. | |
Recently Issued Accounting Pronouncements | |
Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists | |
In July 2013, the FASB issued an amendment to accounting for income taxes which provides guidance on financial statement presentation of an unrecognized tax benefit when an NOL carryforward, a similar tax loss, or a tax credit carryforward exists. The objective in issuing this amendment is to eliminate diversity in practice resulting from a lack of guidance on this topic in current GAAP. Under the amendment, an entity must present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, in the financial statements as a reduction to a deferred tax asset for an NOL carryforward, a similar tax loss, or a tax credit carryforward except under certain conditions. The amendment is effective for fiscal years beginning after December 15, 2013, and interim periods within those years and should be applied to all unrecognized tax benefits that exist as of the effective date. The adoption of this standard is not expected to have an impact on our financial position, results of operations or cash flows. | |
Tangible Personal Property, IRS T.D. 9636 | |
In September 2013, the U.S. Treasury issued final regulations addressing the tax consequences associated with the acquisition, production and improvement of tangible personal property. We continue to evaluate what impact the adoption of the regulations will have on our financial statements. As of this date, we do not expect the adoption of the regulations to have a material impact on our financial statements. |

We have entered into a Utility Money Pool Agreement (the “Agreement”) with BHC, Cheyenne Light and Black Hills Energy.

The Agreement does not restrict us from making 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%.

FAIR VALUE OF FINANCIAL INSTRUMENTS | ||||||||||||||
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. For additional information see Note 1 included in our 2012 Annual Report on Form 10-K filed with the SEC. | ||||||||||||||

(a) | Carrying value approximates fair value due to either short-term length of maturity or variable interest rates that approximate prevailing market rates and therefore is classified in Level 1 in the fair value hierarchy. | |||||||||||||
(b) | Long-term debt is valued using the market approach based on observable inputs of quoted market prices and yields available for debt instruments either directly or indirectly for similar maturities and debt ratings in active markets and therefore is classified in Level 2 in the fair value hierarchy. The carrying amount of our variable rate debt approximates fair value due to the variable interest rates with short reset periods. |

Other than the items discussed below, there have been no significant changes to commitments and contingencies from those previously disclosed in Note 12 of our Notes to the Financial Statements in our 2012 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 megawatts and Cheyenne Light owns 40 megawatts of the facilities 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 $41 million. Construction is expected to be completed by September 30, 2014. As of September 30, 2013 committed contracts for equipment purchases and for construction were 94% and 67% complete, respectively. | |
Oil Creek Fire | |
On June 29, 2012, a forest and grassland fire occurred in the western Black Hills. We subsequently received written damage claims from the State of Wyoming and one landowner seeking recovery for alleged injury to timber, grass, fencing, fire suppression and rehabilitation costs of approximately $8 million. On April 16, 2013, thirty-four private landowners filed suit in United States District Court for the District of Wyoming, asserting similar claims, based upon allegations of negligence, common law nuisance and trespass. The suit seeks recovery of both actual and punitive damages in an unspecified amount. Our investigation into the cause and origin of the fire is pending. We expect to deny and will vigorously defend all claims arising out of the lawsuit, pending the completion of our investigation. Given the uncertainty of litigation, however, a loss related to the fire and the litigation is reasonably possible. We cannot reasonably estimate the amount of a potential loss because our investigation is ongoing. Further claims may be presented by other parties. We cannot predict the outcome of our investigation, the viability of alleged claims, or the outcome of the litigation. Based on information currently available, however, management does not expect the claims, if determined adversely to us, to have a material adverse effect on our financial condition or results of operations. |

[1] | Carrying value approximates fair value due to either short-term length of maturity or variable interest rates that approximate prevailing market rates and therefore is classified in Level 1 in the fair value hierarchy. | |||||
[2] | Long-term debt is valued using the market approach based on observable inputs of quoted market prices and yields available for debt instruments either directly or indirectly for similar maturities and debt ratings in active markets and therefore is classified in Level 2 in the fair value hierarchy. The carrying amount of our variable rate debt approximates fair value due to the variable interest rates with short reset periods. |
