Thanks, Mike. And good morning, everyone.
As Mike indicated in his opening remarks, we reported another solid improvement in earnings compared to the prior year. Earnings benefited from a combination of higher volumes sold, higher unit margins and continued savings from operating efficiencies that helped partially offset higher variable operating costs resulting from higher customer demand.
To be consistent with previous reporting, as I discuss our second quarter results, I'm excluding the impact of unrealized noncash mark-to-market adjustments on derivative instruments used in risk management activities which result in an unrealized loss of $3.7 million in the second quarter of fiscal 2018 compared to unrealized loss of $2.5 million in the prior year. Additionally, net income and EBITDA for the prior year included a loss on debt extinguishment of $1.6 million associated refinancing of our 2021 secured notes. Excluding these items, net income for the second quarter of fiscal 2018 increased to $110.5 million or $1.80 per common unit compared to net income of $87.9 million or $1.44 per common unit in the prior year.
Adjusted EBITDA for the second quarter of fiscal 2018 amounted to $162.1 million, an increase of $24.1 million or 17.5% compared to the prior year.
Retail propane gallons sold in the second quarter of fiscal 2018 of 169.7 million gallons increased 15.8 million gallons or 10.3% compared to the prior year. Sales of fuel oil and other refined fuels of 13.6 million gallons increased 5% compared to the prior year.
Our volumes benefited from cooler temperatures experienced throughout the majority of our service territories, which contributed to an increase in customer demand for heating needs. The year-over-year increase in volumes sold slightly outpaced the increase in heating degree days, which were 9% cooler than the prior year in our service territories. The heating degree days for the quarter were concentrated in January and March, as average temperatures for those months were at near normal levels. However, average temperatures for the month of February were 16% warmer than normal and only slightly cooler than the record warm temperatures in February 2017.
In the commodity markets, price of propane gradually decreased during the quarter but provided a slight tailwind for margin management. The price of propane, basis Mont Belvieu, steadily dropped from $0.97 per gallon at the beginning of the second quarter to $0.80 per gallon at the end of the quarter. Although prices generally declined from January to March, average wholesale prices for the quarter were still 18% higher than Q2 of last year.
Total gross margins of $293.3 million in the second quarter of fiscal 2018 increased $32.7 million or 12.6% compared to the prior year primarily due to higher volumes sold and higher average unit margins. And with respect to expenses, while volumes sold increased more than 10% year-over-year, combined operating and G&A expenses increased 7% compared to the prior year. This increase reflects higher variable operating costs attributed to an increase in deliveries and other operational activities to support higher demand as well as higher variable compensation associated with higher earnings. And I'd also point out that our G&A expenses for the prior year second quarter included a credit of $2 million as a result of reversing accruals for variable compensation to reflect estimated amounts earned at the end of last year's second quarter.
Net interest expense of $19.4 million for the second quarter of fiscal 2018 increased $1.9 million or 11% compared to the prior year primarily due to a higher level of outstanding borrowings on the revolving credit facility. Total capital spending for the quarter -- the total capital spending for the second quarter of 2018 amounted to $9.6 million compared to $10.4 million in the prior year.
And at the beginning of the third quarter, we closed on the acquisition of a propane operation strategically located in our Florida market for a total purchase price of $11.9 million.
And now looking at our year-to-date performance. As Mike indicated, adjusted EBITDA for the first half of fiscal 2018 increased $33 million or nearly 15% compared to the prior year. Earnings benefited from an 8% increase in propane volumes sold and temperatures that were 7% cooler than the prior year in our service territories as well as higher average unit margins and continued operating efficiencies that helped partially offset higher variable operating costs.
And turning to our balance sheet. We have now moved through our historically high period of seasonal working capital needs and, during the second quarter, refunded our working capital and capital expenditures and also paid down revolver borrowings by roughly $36 million from operating cash flow. The combination of the increase in earnings and debt repayment during the second quarter resulted in our consolidated leverage ratio improving to 4.58x at the end of Q2. We are well within our debt covenant requirements and remain focused on restoring our balance sheet strength, which includes achieving a target leverage profile in the mid to upper 3x.
Back to you, Mike.
