(NASDAQ: HTGC), a leader in customized debt financing for entrepreneurial venture capital and private equity-backed companies in technology-related markets including cleantech and life science, announced today that its Board of Directors has declared a fourth quarter cash dividend of $0.23 per share. The dividend will be payable on March 15, 2012, to shareholders of record as of March 12, 2012.

The determination of the tax attributes of the Company’s distributions is made annually as of the end of the Company’s fiscal year based upon its taxable income for the full year and distributions paid for the full year.

The tax attributes of the Company’s distributions for the year ended December 31, 2011 were paid 100% from earnings and profits. There can be no certainty to shareholders that the 2011 determination is representative of what the tax attributes of the Company’s 2012 distributions to shareholders will actually be. The Company’s distributions are intended to be paid from taxable income.
