We are a non-diversified, closed-end investment company that has filed an election to be regulated as a business development company (“BDC”), under the Investment Company Act of 1940, as amended (the “1940 Act”). A goal of a BDC is to annually qualify and elect to be treated as a regulated investment company (“RIC”) under Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”). The Company, however, did not meet the requirements to qualify as a RIC for the 2022 tax year and will be taxed as a corporation under Subchapter C of the Code and does not expect to meet the qualifications of a RIC until such time as certain strategic alternatives are achieved. While we have sought to invest primarily in private small and lower middle-market companies in various industries through first lien loans, second lien loans, unsecured loans, unitranche and mezzanine debt financing, often times with a corresponding equity investment, we are now (with a strategic alternatives process underway and limited resources) investing only in current investments and otherwise conserving cash. Our investment objective is to maximize the total return to our stockholders in the form of current income and capital appreciation through debt and related equity investments.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Prior to March 13, 2015, Princeton Capital’s predecessor operated under the name Regal One Corporation (“Regal One”).

On September 16, 2005, Regal One filed a Form N54A (Notification of Election by Business Development Companies) with the Securities and Exchange Commission (“SEC”), which transformed Regal One into a BDC in accordance with sections 55 through 65 of the 1940 Act. Regal One reported as an operating BDC from March 31, 2006 until March 13, 2015 and since March 13, 2015 (following Regal One’s reincorporation from Florida to Maryland by merging with and into the Company with the Company continuing as the surviving corporation) Princeton Capital has reported as an operating BDC.</p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"> </p><p style="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">On December 27, 2017, the Board approved (specifically in accordance with Rule 15a-4(b)(1)(ii) of the Investment Company Act) and authorized the Company to enter into an Interim Investment Advisory Agreement between the Company and House Hanover, LLC, a Delaware limited liability company (“House Hanover”) (the “Interim Investment Advisory Agreement”), in accordance with Rule 15a-4 of the Investment Company Act.
