Second Fiscal Quarter 2016 Highlights:

Second Fiscal Quarter 2016 Results: Total investment income decreased by 6.0% quarter over quarter due to a lower average interest bearing investment portfolio during the three months ended March 31, 2016, compared to the three months ended December 31, 2015.  Interest and financing expenses decreased by $0.1 million, or 6.5%, compared to the prior quarter due to a reduction in average borrowings on our line of credit. Total non-interest expenses decreased by $0.6 million, or 19.4%, quarter over quarter, primarily due to a $0.7 million decrease in net base management fees and net incentive fees, when compared to the quarter ended December 31, 2015.  Net Investment Income for the quarter ended March 31, 2016 was $4.9 million, or $0.21 per share, compared to $4.8 million, or $0.21 per share for the quarter ended December 31, 2015. 

Net Decrease in Net Assets Resulting from Operations was $6.1 million, or $0.26 per share for the quarter ended March 31, 2016, compared to $8.7 million, or $0.38 per share for the quarter ended December 31, 2015.  The net realized loss and net unrealized depreciation for the quarter ended March 31, 2016 were driven primarily by the markdown of a number of syndicated loans and unrealized depreciation associated with certain energy investments and equity positions.
