The accounting guidance prescribes the method to be used to record the financial transactions of a regulated entity.&amp;#160;&amp;#160;The criteria for applying the accounting for regulated operations include the following: (i) rates are set by an independent third party regulator; (ii) regulated rates are designed to recover the specific costs of the regulated products or services; and (iii) it is reasonable to assume that rates are set at levels that recovered costs can be charged to and collected from customers.&amp;#160;&amp;#160;Management periodically assesses whether the requirements for application of regulatory accounting treatment as allowed by the Regulated Operations Topic of the FASC are satisfied.&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt;

The Utilities will still be required to file an annual DEAA case to review costs for prudency and reasonableness, and if any costs are disallowed on such grounds, the disallowance will be incorporated into the next subsequent quarterly rate change.  &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;See Note 3, &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;font-style:italic;"&gt;Regulatory Actions&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt; for details regarding deferred energy balances.&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top: 0pt; margin-bottom: 0pt;'&gt;&lt;/p&gt;&lt;p style='margin-top:12pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;font-weight:bold;margin-left:0px;"&gt;Energy Efficiency Implementation Rate (EEIR) and Energy Efficiency Program Rate (EEPR)&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;margin-left:0px;"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In 2009, the Nevada Legislature passed Senate Bill 358, which required the PUCN to adopt regulations authorizing an electric utility to recover lost revenue that is attributable to the measurable and verifiable effects associated with the implementation of efficiency and conservation programs approved by the PUCN.  As a result, the PUCN opened Docket No. 09-07016 to amend and adopt the regulation.  The regulation was adopted by the Legislature on July 22, 2010.  As a result, the Utilities file annually in March, to adjust rates and set a clearing rate or EEIR effective in October of the same year for over or under collected balance, similar to the deferred energy mechanism discussed above. In addition, the regulation approved the transition of the recovery &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;for the implementation costs of &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;energy efficiency program&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;s&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt; from general rates (filed every 3 years) to recovery through annual rate filings annually in March, to adjust rates and set a clearing rate or EEPR effective in October of the same year for over or under collected balance, similar to the deferred energy mechanism discussed above.

AFUDC represents the cost of borrowed funds and, where appropriate, the cost of equity funds used for construction purposes in accordance with rules prescribed by the FERC and the PUCN.  AFUDC is capitalized in the same manner as construction labor and material costs, however, with an offsetting credit to &amp;#8220;other income&amp;#8221; for the portion representing the cost of equity funds; and as a reduction of interest charges for the portion representing borrowed funds.  Recognition of this item as a cost of utility plant is in accordance with established regulatory ratemaking practices.  Such practices are intended to permit the Utility to earn a fair return on, and recover in rates charged for utility services, all capital costs.  This is accomplished by including such costs in the rate base and in the provision for depreciation.  NPC's AFUDC rate used during 2011, 2010 and 2009 were &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;8.47&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;%, &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;8.32&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;% and &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;8.57&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;% &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;respectively.  SPPC's AFUDC rates used during 2011, 2010 and 2009 were &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;7.86&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;% (Electric) and &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;5.15&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;% (Gas)&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;font-weight:bold;"&gt;,&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt; 7.85%, &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;7.96&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;% respectively.  (In 2011, separate rates were calculated for electric and gas due to different rates of return allowed by PUCN Docket 10-06002).

Management considers estimates of the amount and character of future taxable income by tax jurisdiction in assessing the likelihood of realization of deferred tax assets.&amp;#160; If it is not more likely than not that a deferred tax asset will be realized in its entirety, a valuation allowance is recorded with respect to the portion estimated not likely to be realized.  &lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;margin-left:36px;"&gt;Tax benefits associated with income tax positions taken, or expected to be taken, in a tax return are recorded only when the more-likely-than-not recognition threshold is satisfied and measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon settlement.&amp;#160; NVE and the Utilities classify interest and penalties associated with unrecognized tax benefits as interest and other expense, respectively, within the income statement.  No interest expense or penalties associated with unrecognized tax benefits have been recorded.&amp;#160; &amp;#160;&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;margin-left:36px;"&gt;The Utilities reduce rates to reflect the current tax benefits associated with recognizing certain tax deductions sooner than when the expenses are recognized for financial reporting purposes. A regulatory asset is recorded for these amounts to reflect the future increases in income taxes payable that will be recovered from customers when these temporary differences reverse. The Utilities have been fully normalized since 1987. AFUDC-equity is recorded on an after-tax basis. Accordingly, a regulatory asset is recorded when AFUDC-equity is recognized. This regulatory asset reverses as the related plant is depreciated, resulting in an increase to the tax provision.&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;margin-left:36px;"&gt;The Utilities also record regulatory liabilities for obligations to reduce rates charged customers for deferred taxes recovered from customers in prior years at corporate tax rates higher than the current tax rates. The reduction in rates charged customers will occur as the temporary differences resulting in the excess deferred tax liabilities reverse.&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;margin-left:36px;"&gt;Investment tax credits are deferred and amortized over the estimated service lives of the related properties.&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top: 0pt; margin-bottom: 0pt;'&gt;&lt;/p&gt;&lt;p style='margin-top:12pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;font-weight:bold;margin-left:0px;"&gt;Revenues&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;margin-left:0px;"&gt;   &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;font-style:italic;"&gt;Unbilled&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;margin-left:36px;"&gt;Revenues related to the sale of energy are recorded based on meter reads, which occur on a systematic basis throughout a month, rather than when the service is rendered or energy is delivered.&amp;#160;&amp;#160;At the end of each month, the energy delivered to the customers from the date of their last meter read to the end of the month is estimated and the corresponding unbilled revenues are calculated.&amp;#160;&amp;#160;These estimates of unbilled sales and revenues are based on the ratio of billable days versus unbilled days, amount of energy procured and generated during that month, historical customer class usage patterns, line loss and the Utilities' current tariffs.&amp;#160;&amp;#160;Accounts receivable as of December 31, 2011, include unbilled receivables of $&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;93&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt; million and $&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;51&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt; million for NPC and SPPC, respectively.&amp;#160;&amp;#160;Accounts receivable as of December 31, 2010, include unbilled receivables of $&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;89&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt; million and $&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;60&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt; million for NPC and SPPC, respectively.&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;font-style:italic;margin-left:0px;"&gt;Alternative Revenues&lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;margin-left:36px;"&gt;As adopted by the PUCN in July 2010, the Utilities were authorized to recover lost revenue that was attributable to the measurable and verifiable effects associated with the implementation of efficiency and conservation programs approved by the PUCN.  The Utilities accounted for the effects of such regulation in accordance with FASC 980-605-25, Alternative Revenue Programs which permits the recording of revenue if all of the following conditions are met: (1) the program allows for automatic adjustment of future rates, (2) the amount of revenues is objectively determinable and probable of recovery, and (3) the additional revenues will be collected within &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;24 months&lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;.
