Analyst · the day for a period of 12 months on the company's website, www.idacorpinc.com
Thanks, Larry, and good afternoon, everyone. I'd like to start with our wishes for a speedy recovery for all those that have been impacted by the super storm Sandy. While we cannot directly relate to the devastation of such a storm, we do understand the threat to life, property and the uncertainty that Mother Nature can cause. In coordination with our neighboring Western utilities, we are offering up line crews and equipment to assist in the restoration efforts in light of the aftermath of the storm.
Before I get into the details of the quarter, I would like to comment on the improvement we have seen in the core business as compared to last year's third quarter.
Operating income, which is a key measure of the overall contribution of the operations of the business, increased almost $41 million over the same period a year ago. As I will discuss, this improvement reflects our efforts to improve the timing of recovery of our investment in plant as well as our operating expenses, combined with weather conditions that helped increase usage during the quarter. While, overall, we had a decrease in net income compared to last year's third quarter due largely to the impact of the income tax examination settlement, the core of our business continues to improve. Some of these tax benefits are ongoing, though the amount recorded in 2011 was very significant. Now I will take a little deeper dive at the results for the quarter. I will begin by reviewing the reconciliation of earnings from third quarter 2011 to third quarter 2012, and then update you on the 2012 key operating and financial metrics.
On Slide 5, we present a reconciliation of net income attributable to IDACORP from the third quarter 2011 to the third quarter 2012. The schedule reflect a decrease in net income of $15 million from $107.1 million to $92.1 million. The full reconciliation table is included in the Form 10-Q we filed this morning.
Operating income increased $40.7 million over last year's third quarter and was positively impacted by $32.1 million due to timely recovery of revenue requirements to rates, including increased rates related to Langley Gulch power plant and certain of our regulatory adjustment mechanisms.
Warmer temperatures, combined with continued customer growth, led to a slight increase in sales volumes and a resulting $3 million increase in operating revenues compared with last year's third quarter.
Cooling degree days were up almost 11% over last year and were more than 40% greater than normal. Precipitation during the quarter, on the other hand, was very close to the same quarter last year but in both quarters, less than normal. Both factors influenced our general business customer usage, especially in the third quarter when rates are higher under our tiered and seasonal rate structure. Reductions in payroll-related expenses increased income by $2.3 million, while the combination of changes in other O&M, depreciation and property tax combined with a decrease in allowance for funds used during construction, or AFUDC, decreased income by $6.9 million compared with third quarter 2011. Largely offsetting this reduction was a $6.8 million change in net income due to the third quarter 2011 reversal of amortization of additional accumulated deferred investment tax credits that had been recorded earlier in 2011 with none recorded in 2012. Based on results to date and expected earnings over the balance of the year, Idaho Power recorded $12.1 million of sharing benefits during the quarter related to the settlement agreement approved by the Idaho Public Utilities Commission in December of 2011. This agreement provides for sharing with customers of the portion of 2012 Idaho jurisdictional earnings exceeding a specified return on year end equity. We recorded $6.3 million as the provision against current revenues to benefit customers through rates. This is compared with the $18.1 million customer benefit recorded in the third quarter of 2011 under a similar mechanism for an overall $11.8 million increase in operating income.
Of the $12.1 million benefit recorded at September 30, $5.8 million represents funded additional pension expense which will benefit Idaho customers by reducing the amount of deferred pension expense that will need to be collected from customers in the future.
Finally, as shown on the table, approximately $56.9 million of previously unrecognized tax benefits were recorded in the third quarter of 2011, which did not recur in the third quarter 2012. That, coupled with other changes in income tax expense, reduced net income $56.4 million excluding any impacts of sharing. Steve Keen will provide further information on income taxes and sharing when I finish my comments. I would now like to share some information on recent retail regulatory activity in Oregon. On September 20, the Oregon Public Utility Commission issued an order approving an approximately $3 million increase in annual base rates for recovery of the Oregon jurisdictional investment in the Langley Gulch natural gas-fired power plant. New Oregon general rates became effective October 1, 2012. I'd now like to update you on the progress on the proposed Boardman to Hemingway transmission line. On October 2, the Bonneville Power Administration issued a statement that it had completed an initial prioritization of potential service arrangements for its customer load in Southeastern Idaho. And while it has yet to make a final decision on service options, BPA identified the Boardman to Hemingway line with a transmission asset swap as a top priority for service options for its fiscal year 2013 and beyond, because the new line and asset swap has the potential to keep BPA costs low relative to other options considered. We anticipate a draft environmental impact statement for the line to be issued in the first half of 2013.Current cost estimates for the project are between $890 million and $940 million, including AFUDC. Idaho Power's estimated share of the cost of the permitting phase of the project, after all partner contributions, is expected to be approximately $13 million, including AFUDC.
Before turning the presentation over to Steve, I'll cover the updates as to our key operating and financial metrics as shown on Slide 6. We have increased the range for operations and maintenance expense by $10 million to reflect an increase in the estimate of additional pension expense that is expected to be recognized due to the Idaho sharing arrangement. The increase in pension expense will be offset by customer funding through our sharing arrangement, so it'll have no impact on reported net income. We have also tightened the estimated hydroelectric generation range to 7.8 million to 8.2 million megawatt-hours. As a reminder, the annual median in hydroelectric generation is 8.6 million megawatt-hours. Based on these assumptions and our expectations for the remainder of 2012, we are increasing our full year IDACORP earnings per share guidance from the range of $3.20 to $3.35 per diluted share to the range of $3.30 to $3.40 per diluted share.
As has been our past practice, we expect to initiate earnings guidance for 2013 beginning with our 2012 year end conference call, which is expected in February 2013. Steve will now discuss IDACORP's expected debt and equity financing requirements for the remainder of 2012, further insight in the Idaho sharing arrangement and our current liquidity position.
