Receipts from the sale of, license to use, or granting of remote access to digital products within and without the state shall be included in the denominator of the apportionment fraction. The taxpayer must exercise due diligence under each method described in paragraph (c) of this subdivision before rejecting it and proceeding to the next method in the hierarchy, and must base its determination on information known to the taxpayer or information that would be known to the taxpayer upon reasonable inquiry. If the receipt for a digital product is comprised of a combination of property and services, it cannot be divided into separate components and is considered to be one receipt regardless of whether it is separately stated for billing purposes. The entire receipt must be allocated by this hierarchy.

(c) Hierarchy of sourcing methods. (1) The customer's primary use location of the digital product;

(2) The location where the digital product is received by the customer, or is received by a person designated for receipt by the customer;

Financial transactions. (a) Financial instruments. A financial instrument is a "nonqualified financial instrument" if it is not a qualified financial instrument. A qualified financial instrument means a financial instrument that is of a type described in any of clauses (A), (B), (C), (D), (G), (H) or (I) of subparagraph two of this paragraph and that has been marked to market in the taxable year by the taxpayer under section 475 or section 1256 of the internal revenue code. Further, if the taxpayer has in the taxable year marked to market a financial instrument of the type described in any of the clauses (A), (B), (C), (D), (G), (H) or (I) of subparagraph two of this paragraph, then any financial instrument within that type described in the above specified clause or clauses that has not been marked to market by the taxpayer under section 475 or section 1256 of the internal revenue code is a qualified financial instrument in the taxable year. Notwithstanding the two preceding sentences, (i) a loan secured by real property shall not be a qualified financial instrument, (ii) if the only loans that are marked to market by the taxpayer under section 475 or section 1256 of the internal revenue code are loans secured by real property, then no loans shall be qualified financial instruments, (iii) stock that is investment capital as defined in paragraph (a) of subdivision five of section two hundred eight of this article shall not be a qualified financial instrument, and (iv) stock that generates other exempt income as defined in subdivision six-a of section two hundred eight of this article and that is not marked to market under section 475 or section 1256 of the internal revenue code shall not constitute a qualified financial instrument with respect to the income from that stock that is described in such subdivision six-a. If a corporation is included in a combined report, the definition of qualified financial instrument shall be determined on a combined basis. In the case of a RIC or a REIT that is not a captive RIC or a captive REIT, a qualified financial instrument means a financial instrument that is of a type described in any of clauses (A), (B), (C), (D), (G), (H) or (I) of subparagraph two of this paragraph, other than (i) a loan secured by real property, (ii) stock that is investment capital as defined in paragraph (a) of subdivision five of section two hundred eight of this article, and (iii) stock that generates other exempt income as defined in subdivision six-a of section two hundred eight of this article with respect to the income from that stock that is described in such subdivision six-a.

(1) Fixed percentage method for qualified financial instruments. In determining the inclusion of receipts and net gains from qualified financial instruments in the apportionment fraction, taxpayers may elect to use the fixed percentage method described in this subparagraph for qualified financial instruments. The election is irrevocable, applies to all qualified financial instruments, and must be made on an annual basis on the taxpayer's original, timely filed return, determined with regard to extensions of time for filing. If the taxpayer elects the fixed percentage method, then all income, gain or loss, including marked to market net gains as defined in clause (J) of subparagraph two of this paragraph, from qualified financial instruments constitutes business income, gain or loss. If the taxpayer does not elect to use the fixed percentage method, then receipts and net gains are included in the apportionment fraction in accordance with the customer sourcing method described in subparagraph two of this paragraph. Under the fixed percentage method, eight percent of all net income (not less than zero) from qualified financial instruments is included in the numerator of the apportionment fraction. All net income (not less than zero) from qualified financial instruments is included in the denominator of the apportionment fraction.

(2) Customer sourcing method. Receipts and net gains from qualified financial instruments, in cases where the taxpayer did not elect to use the fixed percentage method described in subparagraph one of this paragraph, and from nonqualified financial instruments are included in the apportionment fraction in accordance with this subparagraph. For purposes of this paragraph, an individual is deemed to be located in the state if his or her billing address is in the state. A business entity is deemed to be located in the state if its commercial domicile is located in the state.

(A) Loans. (i) Receipts constituting interest from loans secured by real property located within the state shall be included in the numerator of the apportionment fraction. Receipts constituting interest from loans secured by real property located within and without the state shall be included in the denominator of the apportionment fraction.

(ii) Receipts constituting interest from loans not secured by real property shall be included in the numerator of the apportionment fraction if the borrower is located in the state. Receipts constituting interest from loans not secured by real property, whether the borrower is located within or without the state, shall be included in the denominator of the apportionment fraction.

(iii) Net gains (not less than zero) from sales of loans secured by real property are included in the numerator of the apportionment fraction as provided in this subclause. The amount of net gains from the sale of loans secured by real property included in the numerator of the apportionment fraction is determined by multiplying the net gains by a fraction the numerator of which is the amount of gross proceeds from sales of loans secured by real property located within the state and the denominator of which is the gross proceeds from sales of loans secured by real property within and without the state. Gross proceeds shall be determined after the deduction of any cost incurred to acquire the loans but shall not be less than zero. Net gains (not less than zero) from sales of loans secured by real property within and without the state are included in the denominator of the apportionment fraction.

(iv) Net gains (not less than zero) from sales of loans not secured by real property are included in the numerator of the apportionment fraction as provided in this subclause. The amount of net gains from the sale of loans not secured by real property included in the numerator of the apportionment fraction is determined by multiplying the net gains by a fraction, the numerator of which is the amount of gross proceeds from sales of loans not secured by real property to purchasers located within the state and the denominator of which is the amount of gross proceeds from sales of loans not secured by real property to purchasers located within and without the state. Gross proceeds shall be determined after the deduction of any cost incurred to acquire the loans but shall not be less than zero. Net gains (not less than zero) from sales of loans not secured by real property are included in the denominator of the apportionment fraction.

(v) For purposes of this subdivision, a loan is secured by real property if fifty percent or more of the value of the collateral used to secure the loan, when valued at fair market value as of the time the loan was entered into, consists of real property.

(B) Federal, state, and municipal debt. Receipts constituting interest and net gains from sales of debt instruments issued by the United States, any state, or political subdivision of a state shall not be included in the numerator of the apportionment fraction. Receipts constituting interest and net gains (not less than zero) from sales of debt instruments issued by the United States and the state of New York or its political subdivisions shall be included in the denominator of the apportionment fraction. Fifty percent of the receipts constituting interest and net gains (not less than zero) from sales of debt instruments issued by other states or their political subdivisions shall be included in the denominator of the apportionment fraction.

(C) Asset backed securities and other government agency debt. Eight percent of the interest income from asset backed securities or other securities issued by government agencies, including but not limited to securities issued by the Government National Mortgage Association (GNMA), the Federal National Mortgage Association (FNMA), the Federal Home Loan Mortgage Corporation (FHLMC), or the Small Business Administration, or asset backed securities issued by other entities shall be included in the numerator of the apportionment fraction. Eight percent of the net gains (not less than zero) from (i) sales of asset backed securities or other securities issued by government agencies, including but not limited to securities issued by GNMA, FNMA, or FHLMC, the Small Business Administration, or (ii) sales of other asset backed securities that are sold through a registered securities broker or dealer or through a licensed exchange, shall be included in the numerator of the apportionment fraction. The amount of net gains (not less than zero) from sales of other asset backed securities not referenced in subclause (i) or (ii) of this clause included in the numerator of the apportionment fraction is determined by multiplying such net gains by a fraction, the numerator of which is the amount of gross proceeds from such sales to purchasers located in the state and the denominator of which is the amount of gross proceeds from such sales to purchasers located within and without the state. Receipts constituting interest from asset backed securities and other securities referenced in this clause and net gains (not less than zero) from sales of asset backed securities and other securities referenced in this clause are included in the denominator of the apportionment fraction. Gross proceeds shall be determined after the deduction of any cost to acquire the securities but shall not be less than zero.

(D) Corporate bonds. Receipts constituting interest from corporate bonds are included in the numerator of the apportionment fraction if the commercial domicile of the issuing corporation is in the state. Eight percent of the net gains (not less than zero) from sales of corporate bonds sold through a registered securities broker or dealer or through a licensed exchange is included in the numerator of the apportionment fraction. The amount of net gains (not less than zero) from other sales of corporate bonds included in the numerator of the apportionment fraction is determined by multiplying such net gains by a fraction, the numerator of which is the amount of gross proceeds from such sales to purchasers located in the state and the denominator of which is the amount of gross proceeds from sales to purchasers located within and without the state. Receipts constituting interest from corporate bonds, whether the issuing corporation's commercial domicile is within or without the state, and net gains (not less than zero) from sales of corporate bonds to purchasers within and without the state are included in the denominator of the apportionment fraction. Gross proceeds shall be determined after the deduction of any cost to acquire the bonds but shall not be less than zero.

(E) Reverse repurchase agreements and securities borrowing agreements. Eight percent of net interest income (not less than zero) from reverse repurchase agreements and securities borrowing agreements shall be included in the numerator of the apportionment fraction. Net interest income (not less than zero) from reverse repurchase agreements and securities borrowing agreements is included in the denominator of the apportionment fraction. Net interest income from reverse repurchase agreements and securities borrowing agreements is determined for purposes of this subdivision after the deduction of the interest expense from the taxpayer's repurchase agreements and securities lending agreements but cannot be less than zero. For this calculation, the amount of such interest expense is the interest expense associated with the sum of the value of the taxpayer's repurchase agreements where it is the seller/borrower plus the value of the taxpayer's securities lending agreements where it is the securities lender, provided such sum is limited to the sum of the value of the taxpayer's reverse repurchase agreements where it is the purchaser/lender plus the value of the taxpayer's securities lending agreements where it is the securities borrower.

(F) Federal funds. Eight percent of the net interest (not less than zero) from federal funds is included in the numerator of the apportionment fraction. The net interest (not less than zero) from federal funds is included in the denominator of the apportionment fraction. Net interest from federal funds is determined after deduction of interest expense from federal funds.

(G) Dividends and net gains from sales of stock or partnership interests. Dividends from stock, net gains (not less than zero) from sales of stock and net gains (not less than zero) from the sale of partnership interests are not included in either the numerator or denominator of the apportionment fraction unless the commissioner determines pursuant to subdivision eleven of this section that inclusion of such dividends and net gains (not less than zero) is necessary to properly reflect the business income or capital of the taxpayer.

(H) Other financial instruments. (i) Receipts constituting interest from other financial instruments shall be included in the numerator of the apportionment fraction if the payor is located in the state. Receipts constituting interest from other financial instruments, whether the payor is within or without the state, are included in the denominator of the apportionment fraction.

(ii) Net gains (not less than zero) from sales of other financial instruments and other income (not less than zero) from other financial instruments where the purchaser or payor is located in the state are included in the numerator of the apportionment fraction, provided that, if the purchaser or payor is a registered securities broker or dealer or the transaction is made through a licensed exchange, then eight percent of the net gains (not less than zero) or other income (not less than zero) is included in the numerator of the apportionment fraction. Net gains (not less than zero) from sales of other financial instruments and other income (not less than zero) from other financial instruments are included in the denominator of the apportionment fraction.

(I) Physical commodities. Net income (not less than zero) from sales of physical commodities are included in the numerator of the apportionment fraction as provided in this clause. The amount of net income from sales of physical commodities included in the numerator of the apportionment fraction is determined by multiplying the net income from sales of physical commodities by a fraction, the numerator of which is the amount of receipts from sales of physical commodities actually delivered to points within the state or, if there is no actual delivery of the physical commodity, sold to purchasers located in the state, and the denominator of which is the amount of receipts from sales of physical commodities actually delivered to points within and without the state or, if there is no actual delivery of the physical commodity, sold to purchasers located within and without the state. Net income (not less than zero) from sales of physical commodities is included in the denominator of the apportionment fraction. Net income (not less than zero) from sales of physical commodities is determined after the deduction of the cost to acquire or produce the physical commodities.

(J) Marked to market net gains. (i) For purposes of this subdivision, "marked to market" means that a financial instrument is, under section 475 or section 1256 of the internal revenue code, treated by the taxpayer as sold for its fair market value on the last business day of the taxpayer's taxable year. "Marked to market gain or loss" means the gain or loss recognized by the taxpayer under section 475 or section 1256 of the internal revenue code because the financial instrument is treated as sold for its fair market value on the last business day of the taxpayer's taxable year.

(ii) The amount of marked to market net gains (not less than zero) from each type of financial instrument that is marked to market included in the numerator of the apportionment fraction is determined by multiplying the marked to market net gains (but not less than zero) from such type of the financial instrument by a fraction, the numerator of which is the numerator of the apportionment fraction for the net gains from that type of financial instrument determined under the applicable clause of this subparagraph and the denominator of which is the denominator of the apportionment fraction for the net gains for that type of financial instrument determined under the applicable clause of this subparagraph. Marked to market net gains (not less than zero) from financial instruments for which the numerator of the apportionment fraction is determined under the immediately preceding sentence are included in the denominator of the apportionment fraction.

(iii) If the type of financial instrument that is marked to market is not otherwise sourced by the taxpayer under this subparagraph, or if the taxpayer has a net loss from the sales of that type of financial instrument under the applicable clause of this subparagraph, the amount of marked to market net gains (not less than zero) from that type of financial instrument included in the numerator of the apportionment fraction is determined by multiplying the marked to market net gains (but not less than zero) from that type of financial instrument by a fraction, the numerator of which is the sum of the amount of receipts included in the numerator of the apportionment fraction under clauses (A), (B), (C), (D), (E), (F), (G), (H) and (I) of this subparagraph and subclause (ii) of this clause, and the denominator of which is the sum of the amount of receipts included in the denominator of the apportionment fraction under clauses (A), (B), (C), (D), (E), (F), (G), (H) and (I) and subclause (ii) of this clause.

(B) Receipts constituting the primary spread of selling concession from underwritten securities shall be deemed to be generated within the state if the customer is located in the state.

(C) The term "primary spread" means the difference between the price paid by the taxpayer to the issuer of the securities being marketed and the price received from the subsequent sale of the underwritten securities at the initial public offering price, less any selling concession and any fees paid to the taxpayer for advisory services or any manager's fees, if such fees are not paid by the customer to the taxpayer separately. The term "public offering price" means the price agreed upon by the taxpayer and the issuer at which the securities are to be offered to the public.

(4) Receipts from credit card authorization processing, and clearing and settlement processing received by credit card processors shall be deemed to be generated within the state if the location where the credit card processor's customer accesses the credit card processor's network is located within the state. The amount of all other receipts received by credit card processors not specifically addressed in subdivisions one through nine of this section deemed to be generated within the state shall be determined by multiplying the total amount of such other receipts by the average of (i) eight percent and (ii) the percent of its New York access points. The percent of New York access points is the number of locations in New York from which the credit card processor's customers access the credit card processor's network divided by the total number of locations in the United States where the credit card processor's customers access the credit card processor's network.

(d) Receipts from certain services to investment companies. Receipts received from an investment company arising from the sale of management, administration or distribution services to such investment company are included in the denominator of the apportionment fraction. The portion of such receipts included in the numerator of the apportionment fraction (such portion referred to herein as the New York portion) shall be determined as provided in this paragraph.

(1) The New York portion shall be the product of the total of such receipts from the sale of such services and a fraction. The numerator of that fraction is the sum of the monthly percentages (as defined hereinafter) determined for each month of the investment company's taxable year for federal income tax purposes which taxable year ends within the taxable year of the taxpayer (but excluding any month during which the investment company had no outstanding shares). The monthly percentage for each such month is determined by dividing the number of shares in the investment company that are owned on the last day of the month by shareholders that are located in the state by the total number of shares in the investment company outstanding on that date. The denominator of the fraction is the number of such monthly percentages.
