SG&A expenses were $4.1 million for the three months ended September 30, 2013, compared to $5.5 million for the prior-year period. The decrease was primarily due to a $2.0 million decline in Partnership level expenses for business development and unit-based compensation, and lower fees for professional services and unused credit facility fees at the East Dubuque Facility, partially offset by the addition of $1.2 million of SG&A expenses from the Pasadena Facility.
Due to a reduced outlook for profitability at the Pasadena Facility compared to projections made when the Partnership acquired Agrifos, Rentech Nitrogen performed an impairment test for goodwill and determined that the carrying amount of the reporting unit exceeded its fair value. As a result, the Partnership recorded a loss due to goodwill impairment of $30.0 million at its Pasadena Facility during the period. The $30.0 million charge is the Partnership’s best estimate of the probable loss and is subject to further adjustments as the goodwill impairment analysis is finalized at fiscal year-end.
Interest expense was $4.0 million for the three months ended September 30, 2013, compared to $0 for the prior-year period. The increase was attributable to debt incurred for the purchase of the Pasadena Facility and to fund expansion projects at the East Dubuque and Pasadena Facilities.
Rentech Nitrogen realized a non-cash gain of $0.3 million for the three months ended September 30, 2013 as a result of a decrease in the potential earn-out consideration related to the acquisition of Agrifos. The reduction in fair value was primarily due to lower results in 2013 caused by a delayed and abbreviated spring application season and higher levels of urea exports from China, suppressing product prices, and reduced expectations for profits from the Pasadena Facility.Net loss was $22.3 million or ($0.57) per basic unit, for the current period. Excluding the loss on goodwill impairment of $30.0 million and gain on fair value adjustment to earn-out consideration of $0.3 million, net income to common unitholders for the current period was $7.5 million or $0.19 per basic unit. This compares to net income of $28.8 million or $0.75 per basic unit for the same period last year.
