Thank you, Jay, and good morning, everyone. As Jay mentioned, Q2 represented another solid quarter for our company. As is our practice, in just a moment, I'll review in detail the key components of our quarterly financial performance, but I thought it might be useful to deliver the punch line upfront.
Our adjusted EBITDA growth of 8.5% in Q2 2012 as compared to Q2 2011 was primarily a result of further increases in our discharge volume and revenue per discharge, which also contributed to improved operating leverage. As you shall see within the various expense categories, we had items that impacted us, both positively and negatively, for the quarter, with the net of these items being essentially an offset. For example, Q2 2012 benefited from a decrease in our general and professional liability insurance reserve, but this benefit was largely offset by the combination of increased workers' compensation cost, higher bad debt expense and the expenses related to the rollout of our clinical information system. I offer this commentary on the front end so that we don't lose the forest for the trees as we review the details on the quarter.
Now moving into those details. For Q2 2012, revenue grew by 5.6%, driven by a 6.4% increase in inpatient revenue, offset by a 3.3% decline in outpatient and other revenue. The growth in inpatient revenue resulted from a 3% rise in discharge volume, 1.9% on a same-store basis, and a 3.2% increase in revenue per discharge. The 3% discharge growth for the quarter should be viewed in the context of a 6.1% comp from Q2 2011. For the first half of 2012, discharges grew by 4.5% with 3.4% same-store growth.
The factors contributing to the increase in net revenue per discharge were similar to those cited last quarter and included the 1.6% increase in our Medicare reimbursement rates and an increase in the average acuity of our patients. Stroke and neurological comprised 37.2% of our patient mix in Q2 2012 as compared to 33.6% in Q2 2011.
The decline in outpatient and other revenue was primarily attributable to the operation of 3 fewer satellite clinics. At the end of Q2 2012, we operated 26 satellite clinics as compared to 29 at the end of Q2 2011. There were no closures during the quarter.
As anticipated, bad debt expense increased to 1.2% of net operating revenues in Q2 2012 as compared to 1% in Q2 2011. The factors leading to the increase were those we have identified on prior calls, an increase in medical necessity claims reviews and a lengthening in the Medicare denials adjudication process.
During Q2, we again generated improved operating leverage and labor productivity. SWB for the quarter was 48.3% of net operating revenue, an increase of 50 basis points from Q2 2011. The increase was primarily attributable to the anticipated increase in workers' compensation costs and the continued investment in our skills mix, which includes additional certified rehabilitation registered nurses and support personnel for our case management department, which is an outgrowth of our TeamWorks initiative.
Our labor productivity did, however, continue to improve in Q2, as EPOB, which is an acronym for employees per occupied bed, declined to 3.41 from 3.47 a year ago. And as a reminder, when we look at that ratio, lower is better.
We experienced 140 basis points of improved operating leverage in other hospital-related expenses for the quarter. As a reminder, this category includes other operating expenses, supplies and occupancy. Within this category, and as I mentioned at the start of my comments this morning, the benefit of a decrease in our general and professional liability insurance reserves was partially offset by the expenses related to the rollout of our clinical information system.
Flat G&A expense, which includes stock-based compensation and increased revenues, resulted in 30 basis points improvement in G&A as a percent of revenue. The combination of strong revenue growth and improved operating leverage generated adjusted EBITDA of $125.1 million for Q2 2012, an increase of 8.5% over Q2 2011. For the first 6 months of 2012, adjusted EBITDA was $252.1 million, an increase of 8.3% over the first half of 2011.
As we look to the second half of the year, please be reminded that as previously disclosed, we anticipate a higher run rate of bad debt expense, workers' compensation costs and expenses related to our new clinical information system to continue. Additionally, please recall Q4 of 2011 benefited from a $2.4 million nonrecurring franchise tax recovery.
Interest expense for Q2 2012 was $23 million as compared to $34.9 million in Q2 2011. For the time being, we seem to have settled into a run rate of about $23 million per quarter, and that assumption is baked into our revised EPS guidance for 2012. The substantial decline in interest expense from 2011 is attributable to the year-over-year decline in total debt as well as the improvements we have made to our capital structure. You may recall that the 10.75% senior notes still comprise a significant component of our debt capital in Q2 2011.
Diluted EPS from continued operations for Q2 2012 was $0.39 per share as compared to $0.14 per share in Q2 2011. As Jay mentioned earlier, our EPS for the second quarter was reflective of the strong operating results and lower interest expense I just reviewed and included an effective tax rate of approximately 39%. EPS for Q2 2011 included a $10.6 million gain on a recovery from Richard Scrushy, and a $26.1 million loss on early extinguishment of debt arising from our voluntary call of a portion of the then-outstanding 10.75% senior notes. The net after-tax impact of these 2 items on EPS for Q2 2011 was approximately $0.11 per share.
Adjusted free cash flow for Q2 2012 was $70 million, an increase of approximately 10% over Q2 2011. The year-over-year increase stems primarily from our higher adjusted EBITDA and lower interest expense, partially offset by the anticipated increase in maintenance CapEx.
Our maintenance CapEx for Q2 2012 was $31 million as compared to $13.2 million in Q2 2011. Year-to-date maintenance CapEx of $50.1 million compares to $22.3 million for the first 6 months of 2011. We continue to anticipate maintenance CapEx for all of 2012 in a range of $75 million to $85 million. Obviously, this means that our 2012 expenditures have been skewed towards the first half of the year, and that is primarily attributable to the implementation of our planned bed replacement program. Please recall that we also include the capitalized components of our new clinical information system within the maintenance CapEx category.
As Jay discussed in his opening comments during the quarter, we also repurchased 21,645 shares of our preferred stock, bringing our year-to-date total to 46,645 shares at a cost of approximately $46.5 million. These repurchases have the benefit of eliminating the 6.5% annual dividend obligation on the repurchased shares and also reducing our diluted share count by 1.5 million shares. We are now at a run rate on the preferred dividend of $5.74 million per quarter or approximately $23 million per annum. We also reduced our total debt by $26.7 million during the quarter, primarily by means of repaying $25 million on our revolving credit facility and thereby lowering the outstanding principal balance to $100 million at the end of the quarter. These actions resulted in our leverage ratio declining to 2.6x from 2.7x at the end of last quarter. The continued strength in our operating performance and the substantial improvements we made to our balance sheet were acknowledged with upgrades to our credit ratings from both Moody's and S&P during the second quarter. Our bank facilities, which are the senior-most debt obligations in our capital structure, are now rated investment-grade by Moody's.
And now, I'll turn it back to Jay.
