Thanks, Jeff, and good morning, everyone. For the quarter, our home heating oil and propane volume decreased by 7 million gallons, or about 4% to 173 million gallons as colder temperatures and acquisitions were more than offset by the impact of net customer attrition and other factors, including a delivery scheduling variance.
As you might recall, the extremely cold temperatures experienced during the last week of December 2017 favorably impacted volumes sold during the second quarter of fiscal 2018 by an estimated 5 million to 6 million gallons. Temperatures for the fiscal 2019 second quarter were 3% colder than last year, but still 2.6% warmer than normal. Volume of our other petroleum products sold increased by 9 million gallons or 30% to 39 million gallons largely due to acquisitions.
Our product gross profit increased by $2 million or 1% to $222 million as an increase in home heating oil and propane margins was almost totally offset by the decline in home heating oil and propane volumes sold, again driven largely by the delivery scheduling variance. Gross profit generated from other petroleum products decreased by $2 million, large -- increased by $2 million, I'm sorry, by $2 million largely due to acquisitions. Delivery and branch expenses increased by $4 million or 4% to $111 million during the quarter, again largely due to acquisitions, which accounted for $5 million of the increase.
In the base business, insurance expense was lower by $2 million, and the quarter-to-quarter comparison was adversely impacted by a $1 million credit recorded under our weather hedge in the second quarter of fiscal 2018. We posted net income of $72 million or $18 million higher than the prior year as a noncash favorable change in the fair value of derivative instruments of $25 million was offset by a decline in adjusted EBITDA of $5 million. The company also benefited from a decline in the effective tax rate to 29% for the second quarter of fiscal 2019 from 34% during the second quarter of fiscal 2018.
Adjusted EBITDA decreased by $5.3 million or about 5% to $99.5 million as the additional adjusted EBITDA provided by acquisitions of $3.4 million was more than offset by an $8.7 million decline in adjusted EBITDA in the base business.
In looking at the base business, adjusted EBITDA did rise by about $750,000 as the impact of colder temperatures and higher home heating oil and propane margins more than offset some higher operating expenses and the impact of the previously mentioned delivery scheduling volume variance.
However, adjusted EBITDA in the base business was reduced by several factors: $3.8 million due to the implementation of the new revenue recognition standard, of which the majority is expected to be reversed by the end of fiscal 2019; $2.2 million of higher legal and professional expenses; a charge of $1.5 million related to the discontinued use of our tank monitoring system; and an adjusted EBITDA loss of $600,000 associated with the company's concierge program, which was greatly reduced this past January; and lastly, $1.3 million of expense tied to an unfavorable change in Star's weather hedge.
For the first half of fiscal 2019, our home heating oil and propane volume increased by 3 million gallons or 1% to 287 million gallons as colder temperatures and acquisitions more than offset the impact of net customer attrition and other factors. Temperatures for the first half of fiscal 2018 were 4% colder than last year, but still about 2% warmer than normal. Volume of other petroleum products sold increased by 20 million gallons or 33% to 81 million gallons largely due to acquisitions.
Our product gross profit increased by $31 million or 9% to $374 million due to higher home heating oil and propane volumes sold at higher margins and an acquisition-driven increase in gross profit from other petroleum products. Delivery and branch expenses increased $16 million or 8% to $213 million partly due to acquisitions, which accounted for $9 million of the increase and a $7 million increase in the base business due to higher bad debt expense, credit credit card processing fees, the concierge program, additional vehicle operating expenses and inflationary pressures.
We posted net income for the 6 months of fiscal 2019 of $75 million or about $10 million lower than the prior year period as a noncash unfavorable change in the fair value of derivative instruments of $17 million and a hiring effective -- for higher effective income tax rate was partially offset by an increase in adjusted EBITDA of $12 million.
Adjusted EBITDA increased by $12 million or 9% to $144 million. Acquisitions provided $5.1 million of the increase. And in the base business, adjusted EBITDA rose by $7 million. The impact of colder temperatures and higher home heating oil and propane margins in the base business more than offset greater total operating expenses, improving the year-over-year adjusted EBITDA by $17.5 million.
However, adjusted EBITDA in the base business was reduced by several factors: $3.2 million due to the implementation of the revenue recognition standard; $2.6 million of higher legal and professional expenses; a charge of $1.5 million related to the abandonment of our tank monitoring program; and an adjusted EBITDA loss of $3 million associated with the company's concierge program, which I have mentioned that we've pretty much curtailed this past January.
And with that, I'd like to turn the call back over to Jeff.
