Thank you. Good morning, ladies and gentlemen, and welcome to Sterling Construction Company's third quarter 2012 conference call. I'm joined by Peter MacKenna, our Chief Executive Officer; and Brian Manning, Executive Vice President and Chief Business Development Officer.
I would like to remind you that this call may include certain statements that fall within the definition of forward-looking statements under the Private Securities Litigation Reform Act of 1995. Any such statements are subject to risks and uncertainties, including overall economic and market conditions; competitors; customers and suppliers' actions; weather conditions; and other risks identified in our filings with the Securities and Exchange Commission, which could result in actual results to differ materially from those anticipated. Any such statements should be considered in light of these risks.
Predictions that we may make at any time may not continue to reflect management's belief, and we do not undertake to publicly update them.
Results for the third quarter were a disappointment to us. While third quarter revenues increased 29% as compared to 2011 third quarter, gross margins declined to 6.9% for the quarter, leaving us at 6.6% for the 2012 year-to-date gross margin. The increase in revenues for the quarter and 9 months ended September 30, 2012, continues to be in line with our expectation of a 25% overall increase for the full year of 2012 over 2011.
Our new California and Arizona operations contributed $48.8 million in revenues in the quarter as compared to $1.9 million in 2011 third quarter. While we also saw higher revenues in Utah, where we had higher activity levels and improvements in estimated profitability on certain projects, in addition, revenues in Nevada increased quarter-over-quarter, in part from the $25 million in contracts assumed from a third-party in January 2012.
Gross margin at 6.9% in the third quarter of 2012 was below the 9.3% for the third quarter of 2011 and below the 9.0% for the second quarter of 2012. During the quarter, downward revisions in profitability on projects in Texas substantially offset upward revisions on certain projects in Utah.
Diluted earnings per share was $0.01 for the quarter as compared to $0.21 for the 2011 third quarter. Basic and diluted EPS included $0.05 related to the increase in the RLW put call liability. In accordance with GAAP, revisions to the estimated liability are reported directly to retained earnings and do not impact net income. But these are taken into consideration in computing EPS.
Earnings attributable to the noncontrolling interest owners reduced diluted EPS by $0.12 net of the related tax impact in the 2012 third quarter as compared to $0.10 in the 2011 third quarter. A significant portion of this impact is attributable to the 20% of RLW held by non-controlling interest owners.
Higher profits in Utah was a main contributor to the increase. General and administrative expenses for the 2012 third quarter increased $3.2 million as compared to the 2011 third quarter. As a percent of revenues, G&A was 5% versus 4 -- 4% in the prior year quarter. As in the first and second quarters of 2012, some of the increase in G&A is attributable to the expanded California and Arizona operations, in some, as a result of higher professional fees. In addition, we incurred roughly $1 million related to our CEO transition.
Capital expenditures were $27.8 million for the year-to-date 2012 period, and we do not expect significant capital expenditures during the fourth quarter 2012. While CapEx will be higher in 2012 than the $24 million incurred in 2011, proceeds from disposals of property and equipment were $11.9 million year-to-date in 2012 versus $1.3 million for the full 2011 year.
As mentioned previously, increased sales and purchases of equipment in 2012 are a result of efforts in Texas and other markets to ensure that we have right-sized an efficient fleet.
Our overall effective tax rate for the 3 months ended September 30, 2012, was impacted by $3.1 million of earnings allocated to noncontrolling interest owners. After adjusting for this impact, the overall effective tax rate was 46.1% for the third quarter and reflects the impact on interim results of changes in the overall estimated effective tax rate for 2012.
I wanted to highlight a change in the timing of including awards and backlog, beginning in this period. Prior to this reporting period, projects were included in backlog and when they became the apparent low bidder rather than when they were officially awarded. Historically, it was rare for a contract to not be awarded to the apparent low bidder. With the expansion into new markets, especially in California, there's a greater risk that the awarding of contracts to the low bidder are challenged. And therefore, we concluded that a change to the timing of reporting was now appropriate. In the third quarter 2012, earnings release and Form 10-Q and going forward, any previously reported backlog and awards have been and will be restated to exclude contracts not yet officially awarded.
Backlog at September 2012 remain strong at $704 million, and as just explained, excludes $79 million of potential new contract awards as of September 30.
Estimated gross margins in our backlog are comparable to margins on our 2012 year-to-date results of 6.6%. This reflects the impact of projects bid prior to 2012 and on which we have made downward revisions late in 2011 or during 2012.
Sterling continues to be in very sound financial condition. Net working capital at quarter end totaled $82.6 million. And since June 30, 2012, net working capital includes the current liability of $23.3 million associated with the RLW put call. As a reminder, this put call is exercisable beginning in the second quarter of 2013.
We have $38.2 million in availability under our credit facility at the end of the quarter, with the ability to increase the facility by an additional $50 million.
I will now turn the call over to our CEO, Peter MacKenna.
