Thank you, and good morning, everyone. As Suzanne mentioned, The Laclede Group did indeed have a good fourth quarter that capped off a strong performance for fiscal 2012. In reviewing our performance, I first want to spend a little time talking about revenue trends.
For the fiscal year, our operating revenues declined by $478 million or nearly 30% compared to 2011. In other industries, that decline would be alarming. But in our case, it was largely driven by lower commodity prices. For Laclede Gas Company, it's important to remember that a substantial portion, about 60% to 70% of our sales revenues, are tied directly to the cost of natural gas, which is passed through to our utility customers.
Our revenues also declined, and sales volumes were down about 19% this year due in large part to an unseasonably warm winter. In fact, we had the warmest winter in more than 100 years. Despite these warm temperatures, our weather mitigation rate design allowed us to largely protect our margins.
In Laclede Energy Resources, or LER, revenues were also down. This was due not only to the effects of lower commodity costs but also the result of LER taking advantage of marketplace opportunities to optimize its portfolio. It did this by filling its physical positions at certain delivery points with offset in purchases and sales at the same locations. As a result, LER was still able to satisfy its customers and supplier commitments without having to incur fuel costs to transport gas to a different location.
We began recording these types of transactions on a net rather than a gross revenue basis in the second quarter of 2012. And while this resulted in lower recorded operating revenues, it had no effect on earnings. The impact of the change on operating revenues in 2012 compared to 2011 was approximately $173 million.
Now let's turn our attention to fourth quarter earnings. Laclede Group posted consolidated net economic earnings of $0.02 per fully diluted share for the fourth quarter compared to a loss of $0.14 per share last year. This represents an improvement in the year-over-year performance of $3.5 million. This also marks the first time since 2007 that we have delivered positive net economic earnings in the fourth quarter, a period that is typically difficult from an earnings standpoint due to the low level of demand for natural gas during the summer months. This improved performance was primarily driven by a smaller seasonal loss of $3 million in our Regulated Gas Distribution segment as compared to a loss of $6 million in 2011.
A large part of this improvement was due to increased revenues from our Infrastructure System Replacement Surcharge, or ISRS for short, lower maintenance and customer service expenses and higher other income. As a reminder, ISRS is a nominal monthly customer charge that enables the gas company to begin recovering some of its costs associated with mandated distribution system improvements and safety related projects that are completed in between rate cases.
Quarterly net economic earnings for the Non-Regulated Gas Marketing segment, principally LER, were about $3 million, down just slightly from last year due to lower sales margins reflecting the current market environment.
Now looking at our performance for the full year, our net economic earnings in 2012 of approximately $62 million or $2.79 per share matched that of the prior year. And as the table in the beginning of today's earnings release indicates, 2011 results included a $0.27 per share earnings benefit from a sale of propane inventory that did not recur in 2012. Year-over-year earnings growth excluding this sale was 11%.
Both of our primary business segments contributed to this year's better performance. Regulated Gas Distribution grew its net economic earnings by approximately 3% to $48 million. This was mainly due to lower maintenance and customer service expenses and higher ISRS revenues, offset in part by higher benefit costs. Net economic earnings for the Non-Regulated Gas Marketing segment were $12 million, up 37% from 2011. This improvement was the result of lower fixed transportation charges, lower pipeline fuel costs and pipeline optimization activities.
In addition to solid earnings, cash flows were also strong in 2012. We generated over $128 million of cash flow from operating activities. And while that amount was down from the prior year, the difference was largely reflective of changes in working capital requirements resulting from lower gas prices. This cash flow helped us support our 2012 capital spend, which totaled nearly $100 million, up from $68 million in 2011, as we replaced about 41 miles of pipeline, double the amount replaced last year. This reflects the continued ramp up over the last several years in the replacement of portions of our distribution system to ensure its continued safety and reliability.
The increase in 2012 capital spend also included continued investments in our information technology, which Suzanne will discuss further in her remarks.
Looking ahead to 2013, we anticipate that our capital spend will continue to increase to approximately $115 million, as a larger amount of investment in pipeline replacements more than offset the slight decline in IT spending.
Turning to the balance sheet. We ended 2012 in a very solid financial position. Our year-end capitalization was strong, and we have ample liquidity, including lines of credit totaling $350 million, most of which have a 5-year term.
During the fourth quarter, we announced several financing commitments, including private placements of medium-term debt totaling $125 million at fixed rates ranging from 3% to 3.4%. We were pleased to be able to take advantage of the very favorable financing environment and secure such historically low interest rates. These placements enable us to fund our planned capital expenditures and also help replace $25 million of 6.5% debt that we redeemed last month.
To summarize, Laclede delivered good results for 2012 and has a strong balance sheet, and we are well positioned for continued success as we move forward into 2013.
Now let me turn it back over to Suzanne.
