Example 1. (i) Investment Company W at the close of its first quarter of its taxable year has its assets invested as follows: (ii) Investment Company W owns all of the voting stock of Corporations A and B, 15 percent of the voting stock of Corporation C, and less than 10 percent of the voting stock of regulated investment companies and various other corporations. Neither Corporation A nor Corporation B owns:

(A) 20 percent or more of the voting stock of any other corporation;

(B) Securities issued by Corporation C; or

(C) Securities issued by any of the regulated investment companies or various corporations whose securities are owned by Investment Company W. Except for Corporation A and Corporation B, none of the corporations (including the regulated investment companies) is a member of a controlled group with Investment Company W.

(iii) Investment Company W meets the requirements under section 851(b)(3) at the end of its first quarter. It complies with subparagraph (A) of section 851(b)(3) because it has 55 percent of its assets invested as provided in that subparagraph. It complies with subparagraph (B) of section 851(b)(3) because it does not have more than 25 percent of its assets invested in the securities of any one issuer, of two or more issuers that it controls, or of one or more qualified publicly traded partnerships (as defined in section 851(h)).

Example 2. (i) Investment Company V at the close of a particular quarter of the taxable year has its assets invested as follows: (ii) Investment Company V fails to meet the requirements of subparagraph (A) of section 851(b)(3) since its assets invested in Corporations A, B, C, and D exceed in each case 5 percent of the value of the total assets of the company at the close of the particular quarter.

Example 3. (i) Investment Company X at the close of a particular quarter of the taxable year has its assets invested as follows: (ii) Investment Company X owns more than 20 percent of the voting power of Corporations B and C and less than 10 percent of the voting power of all of the other corporations. Corporation B manufactures radios and Corporation C acts as its distributor and also distributes radios for other companies. Investment Company X fails to meet the requirements of subparagraph (B) of section 851(b)(3) since it has 35 percent of its assets invested in the securities of two issuers which it controls and which are engaged in related trades or businesses.

Example 4. (i) Investment Company Y at the close of a particular quarter of its taxable year has its assets invested as follows: (ii) Corporation K has 20 percent of its assets invested in Corporation L, and Corporation L has 40 percent of its assets invested in Corporation B. Corporation A also has 30 percent of its assets invested in Corporation B. Investment Company Y owns more than 20 percent of the voting power of Corporations A and K. Corporation K owns more than 20 percent of the voting power of Corporation L.

(iii) At the end of that quarter, Investment Company Y is disqualified under subparagraph (B)(i) of section 851(b)(3) because, after applying section 851(c)(1), more than 25 percent of the value of Investment Company Y's total assets is invested in the securities of Corporation B. This result is shown by the following calculation:

Example 5. Investment Company Z, which keeps its books and makes its returns on the basis of the calendar year, at the close of the first quarter of 2016 meets the requirements of section 851(b)(3) and has 20 percent of its assets invested in Corporation A. Later during the taxable year it makes distributions to its shareholders and because of such distributions, it finds at the close of the taxable year that it has more than 25 percent of its remaining assets invested in Corporation A. Investment Company Z does not lose its status as a regulated investment company for the taxable year 2016 because of such distributions, nor will it lose its status as a regulated investment company for any subsequent year solely as a result of such distributions. See section 851(d)(1).

Example 6. Investment Company Q, which keeps its books and makes its returns on the basis of the calendar year, at the close of the first quarter of 2016 meets the requirements of section 851(b)(3) and has 20 percent of its assets invested in Corporation P. At the close of the taxable year 2016, it finds that it has more than 25 percent of its assets invested in Corporation P. This situation results entirely from fluctuations in the market values of the securities in Investment Company Q's portfolio and is not due in whole or in part to the acquisition of any security or other property. Investment Company Q does not lose its status as a regulated investment company for the taxable year 2016 because of such fluctuations in the market values of the securities in its portfolio, nor will it lose its status as a regulated investment company for any subsequent year solely as a result of such market value fluctuations. See section 851(d)(1).

Example 7. (i) Investment Company T at the close of a particular quarter of its taxable year has its assets invested as follows: (ii) Investment Company T owns more than 20 percent of the voting power of Corporation A and less than 10 percent of the voting power of all of the other corporations. Corporation A has 80 percent of its assets invested in qualified publicly traded partnerships.

(iii) Investment Company T is disqualified under subparagraph (B)(iii) of section 851(b)(3), because, after applying section 851(c)(1), more than 25 percent of the value of Investment Company T's total assets is invested in the securities of one or more qualified publicly traded partnerships. This result is shown by the following calculation:
