(a) General rule
For purposes of this subtitle, the term "regulated investment company" means any domestic corporation—

(1) which, at all times during the taxable year—

(A) is registered under the Investment Company Act of 1940, as amended (15 U.S.C. 80a–1 to 80b–2) as a management company or unit investment trust, or

(B) has in effect an election under such Act to be treated as a business development company, or

(2) which is a common trust fund or similar fund excluded by section 3(c)(3) of such Act (15 U.S.C. 80a–3(c)) from the definition of "investment company" and is not included in the definition of "common trust fund" by section 584(a).

(b) Limitations
A corporation shall not be considered a regulated investment company for any taxable year unless—

(1) it files with its return for the taxable year an election to be a regulated investment company or has made such election for a previous taxable year;

(2) at least 90 percent of its gross income is derived from—

(A) dividends, interest, payments with respect to securities loans (as defined in section 512(a)(5)), and gains from the sale or other disposition of stock or securities (as defined in section 2(a)(36) of the Investment Company Act of 1940, as amended) or foreign currencies, or other income (including but not limited to gains from options, futures or forward contracts) derived with respect to its business of investing in such stock, securities, or currencies, and

(B) net income derived from an interest in a qualified publicly traded partnership (as defined in subsection (h)); and

(3) at the close of each quarter of the taxable year—

(A) at least 50 percent of the value of its total assets is represented by—

(i) cash and cash items (including receivables), Government securities and securities of other regulated investment companies, and

(ii) other securities for purposes of this calculation limited, except and to the extent provided in subsection (e), in respect of any one issuer to an amount not greater in value than 5 percent of the value of the total assets of the taxpayer and to not more than 10 percent of the outstanding voting securities of such issuer, and

(B) not more than 25 percent of the value of its total assets is invested in—

(i) the securities (other than Government securities or the securities of other regulated investment companies) of any one issuer,

(ii) the securities (other than the securities of other regulated investment companies) of two or more issuers which the taxpayer controls and which are determined, under regulations prescribed by the Secretary, to be engaged in the same or similar trades or businesses or related trades or businesses, or

(iii) the securities of one or more qualified publicly traded partnerships (as defined in subsection (h)).

For purposes of paragraph (2), there shall be treated as dividends amounts included in gross income under section 951(a)(1)(A) or 1293(a) for the taxable year to the extent that, under section 959(a)(1) or 1293(c) (as the case may be), there is a distribution out of the earnings and profits of the taxable year which are attributable to the amounts so included. For purposes of paragraph (2), the Secretary may by regulation exclude from qualifying income foreign currency gains which are not directly related to the company's principal business of investing in stock or securities (or options and futures with respect to stock or securities). For purposes of paragraph (2), amounts excludable from gross income under section 103(a) shall be treated as included in gross income. Income derived from a partnership (other than a qualified publicly traded partnership as defined in subsection (h)) or trust shall be treated as described in paragraph (2) only to the extent such income is attributable to items of income of the partnership or trust (as the case may be) which would be described in paragraph (2) if realized by the regulated investment company in the same manner as realized by the partnership or trust.

(c) Rules applicable to subsection (b)(3)
For purposes of subsection (b)(3) and this subsection—

(1) In ascertaining the value of the taxpayer's investment in the securities of an issuer, for the purposes of subparagraph (B), there shall be included its proper proportion of the investment of any other corporation, a member of a controlled group, in the securities of such issuer, as determined under regulations prescribed by the Secretary.

(2) The term "controls" means the ownership in a corporation of 20 percent or more of the total combined voting power of all classes of stock entitled to vote.

(3) The term "controlled group" means one or more chains of corporations connected through stock ownership with the taxpayer if—

(A) 20 percent or more of the total combined voting power of all classes of stock entitled to vote of each of the corporations (except the taxpayer) is owned directly by one or more of the other corporations, and

(B) the taxpayer owns directly 20 percent or more of the total combined voting power of all classes of stock entitled to vote, of at least one of the other corporations.

(4) The term "value" means, with respect to securities (other than those of majority-owned subsidiaries) for which market quotations are readily available, the market value of such securities; and with respect to other securities and assets, fair value as determined in good faith by the board of directors, except that in the case of securities of majority-owned subsidiaries which are investment companies such fair value shall not exceed market value or asset value, whichever is higher.

(5) The term "outstanding voting securities of such issuer" shall include the equity securities of a qualified publicly traded partnership (as defined in subsection (h)).

(6) All other terms shall have the same meaning as when used in the Investment Company Act of 1940, as amended.

(d) Determination of status

(1) In general
A corporation which meets the requirements of subsections (b)(3) and (c) at the close of any quarter shall not lose its status as a regulated investment company because of a discrepancy during a subsequent quarter between the value of its various investments and such requirements unless such discrepancy exists immediately after the acquisition of any security or other property and is wholly or partly the result of such acquisition. A corporation which does not meet such requirements at the close of any quarter by reason of a discrepancy existing immediately after the acquisition of any security or other property which is wholly or partly the result of such acquisition during such quarter shall not lose its status for such quarter as a regulated investment company if such discrepancy is eliminated within 30 days after the close of such quarter and in such cases it shall be considered to have met such requirements at the close of such quarter for purposes of applying the preceding sentence.

(2) Special rules regarding failure to satisfy requirements
If paragraph (1) does not preserve a corporation's status as a regulated investment company for any particular quarter—

(A) In general
A corporation that fails to meet the requirements of subsection (b)(3) (other than a failure described in subparagraph (B)(i) of this paragraph) for such quarter shall nevertheless be considered to have satisfied the requirements of such subsection for such quarter if—

(i) following the corporation's identification of the failure to satisfy the requirements of such subsection for such quarter, a description of each asset that causes the corporation to fail to satisfy the requirements of such subsection at the close of such quarter is set forth in a schedule for such quarter filed in the manner provided by the Secretary,

(ii) the failure to meet the requirements of such subsection for such quarter is due to reasonable cause and not due to willful neglect, and

(iii)

(I) the corporation disposes of the assets set forth on the schedule specified in clause (i) within 6 months after the last day of the quarter in which the corporation's identification of the failure to satisfy the requirements of such subsection occurred or such other time period prescribed by the Secretary and in the manner prescribed by the Secretary, or

(II) the requirements of such subsection are otherwise met within the time period specified in subclause (I).

(B) Rule for certain de minimis failures
A corporation that fails to meet the requirements of subsection (b)(3) for such quarter shall nevertheless be considered to have satisfied the requirements of such subsection for such quarter if—

(i) such failure is due to the ownership of assets the total value of which does not exceed the lesser of—

(I) 1 percent of the total value of the corporation's assets at the end of the quarter for which such measurement is done, or

(II) $10,000,000, and

(ii)

(I) the corporation, following the identification of such failure, disposes of assets in order to meet the requirements of such subsection within 6 months after the last day of the quarter in which the corporation's identification of the failure to satisfy the requirements of such subsection occurred or such other time period prescribed by the Secretary and in the manner prescribed by the Secretary, or

(II) the requirements of such subsection are otherwise met within the time period specified in subclause (I).

(C) Tax

(i) Tax imposed
If subparagraph (A) applies to a corporation for any quarter, there is hereby imposed on such corporation a tax in an amount equal to the greater of—

(I) $50,000, or

(II) the amount determined (pursuant to regulations promulgated by the Secretary) by multiplying the net income generated by the assets described in the schedule specified in subparagraph (A)(i) for the period specified in clause (ii) by the highest rate of tax specified in section 11.

(ii) Period
For purposes of clause (i)(II), the period described in this clause is the period beginning on the first date that the failure to satisfy the requirements of subsection (b)(3) occurs as a result of the ownership of such assets and ending on the earlier of the date on which the corporation disposes of such assets or the end of the first quarter when there is no longer a failure to satisfy such subsection.

(iii) Administrative provisions
For purposes of subtitle F, a tax imposed by this subparagraph shall be treated as an excise tax with respect to which the deficiency procedures of such subtitle apply.

(e) Investment companies furnishing capital to development corporations

(1) General rule
If the Securities and Exchange Commission determines, in accordance with regulations issued by it, and certifies to the Secretary not earlier than 60 days prior to the close of the taxable year of a management company or a business development company described in subsection (a)(1), that such investment company is principally engaged in the furnishing of capital to other corporations which are principally engaged in the development or exploitation of inventions, technological improvements, new processes, or products not previously generally available, such investment company may, in the computation of 50 percent of the value of its assets under subparagraph (A) of subsection (b)(3) for any quarter of such taxable year, include the value of any securities of an issuer, whether or not the investment company owns more than 10 percent of the outstanding voting securities of such issuer, the basis of which, when added to the basis of the investment company for securities of such issuer previously acquired, did not exceed 5 percent of the value of the total assets of the investment company at the time of the subsequent acquisition of securities. The preceding sentence shall not apply to the securities of an issuer if the investment company has continuously held any security of such issuer (or of any predecessor company of such issuer as determined under regulations prescribed by the Secretary) for 10 or more years preceding such quarter of such taxable year.

(2) Limitation
The provisions of this subsection shall not apply at the close of any quarter of a taxable year to an investment company if at the close of such quarter more than 25 percent of the value of its total assets is represented by securities of issuers with respect to each of which the investment company holds more than 10 percent of the outstanding voting securities of such issuer and in respect of each of which or any predecessor thereof the investment company has continuously held any security for 10 or more years preceding such quarter unless the value of its total assets so represented is reduced to 25 percent or less within 30 days after the close of such quarter.

(3) Determination of status
For purposes of this subsection, unless the Securities and Exchange Commission determines otherwise, a corporation shall be considered to be principally engaged in the development or exploitation of inventions, technological improvements, new processes, or products not previously generally available, for at least 10 years after the date of the first acquisition of any security in such corporation or any predecessor thereof by such investment company if at the date of such acquisition the corporation or its predecessor was principally so engaged, and an investment company shall be considered at any date to be furnishing capital to any company whose securities it holds if within 10 years prior to such date it has acquired any of such securities, or any securities surrendered in exchange therefor, from such other company or predecessor thereof. For purposes of the certification under this subsection, the Securities and Exchange Commission shall have authority to issue such rules, regulations and orders, and to conduct such investigations and hearings, either public or private, as it may deem appropriate.
