The net income of a financial service company shall be apportioned to this state by multiplying such income by the receipts factor. The receipts factor for a financial service company is a fraction, the numerator of which is the receipts of the taxpayer in this state during the income year and the denominator of which is the receipts of the taxpayer within and without this state during the income year. The method of calculating receipts for purposes of the denominator is the same as the method used in determining receipts for purposes of the numerator.

(2) Any receipts attributable to an international banking facility, as defined in § 12-217, shall not be included in the numerator or denominator of the receipts factor. In lieu of such exclusion of receipts attributable to an international banking facility, the taxpayer, pursuant to the provisions of subdivision (3) of this subsection, may, on or before the due date or, if applicable, the extended due date, of its corporation business tax return, make an election on its corporation business tax return, to exclude receipts attributable to an international banking facility from the numerator of its receipts factor and to include such receipts in the denominator of its receipts factor.

If the extent of the use of any transportation property within this state cannot be determined, the property shall be deemed to be used wholly in the state in which the property has its principal base of operations. A motor vehicle shall be deemed to be used wholly in the state in which it is registered.

If the property is located both within this state and one or more other states, the receipts described in this subsection are included in the numerator of the receipts factor if more than fifty per cent of the fair market value of the real property is located within this state. If more than fifty per cent of the fair market value of the real property is not located within any one state, the receipts described in this subsection shall be included in the numerator of the receipts factor if the borrower is located in this state.

(2) The determination of whether the real property securing a loan is located within this state shall be made as of the time the original agreement was made and all subsequent substitutions of collateral shall be disregarded.

(2) The amount of net gains, but not less than zero, from the sale of loans secured by real property included in the numerator is determined by multiplying such net gains by a fraction the numerator of which is the amount included in the numerator of the receipts factor pursuant to subsection (e) of this section and the denominator of which is the total amount of interest and fees or penalties in the nature of interest from loans secured by real property.

(3) The amount of net gains, but not less than zero, from the sale of loans not secured by real property included in the numerator is determined by multiplying such net gains by a fraction the numerator of which is the amount included in the numerator of the receipts factor pursuant to subsection (f) of this section and the denominator of which is the total amount of interest and fees or penalties in the nature of interest from loans not secured by real property.

(h) (1) The numerator of the receipts factor includes loan servicing fees derived from loans secured by real property multiplied by a fraction the numerator of which is the amount included in the numerator of the receipts factor pursuant to subsection (e) of this section and the denominator of which is the total amount of interest and fees or penalties in the nature of interest from loans secured by real property.

(2) The numerator of the receipts factor includes loan servicing fees derived from loans not secured by real property multiplied by a fraction the numerator of which is the amount included in the numerator of the receipts factor pursuant to subsection (f) of this section and the denominator of which is the total amount of interest and fees or penalties in the nature of interest from loans not secured by real property.

(3) In circumstances in which the taxpayer receives loan servicing fees for servicing either the secured or the unsecured loans of another, the numerator of the receipts factor shall include such fees if the borrower is located in this state.

Investment assets and activities and trading assets and activities include, but are not limited to, investment securities, trading account assets, federal funds, securities purchased and sold under agreements to resell or repurchase, options, futures contracts, forward contracts, notional principal contracts such as swaps, equities, and foreign currency transactions. With respect to the investment and trading assets and activities described in subparagraphs (A) and (B) of this subdivision, the receipts factor shall include the amounts described in said subparagraphs (A) and (B).

(A) The receipts factor shall include the amount by which interest from federal funds sold and securities purchased under resale agreements exceeds interest expense on federal funds purchased and securities sold under repurchase agreements.

(A) The amount of interest, dividends, net gains, but not less than zero, and other income from investment assets and activities in the investment account to be attributed to this state and included in the numerator is determined by multiplying all such income from such assets and activities by a fraction, the numerator of which is the average value of such assets which are properly assigned to a regular place of business of the taxpayer within this state and the denominator of which is the average value of all such assets.

(B) The amount of interest from federal funds sold and purchased and from securities purchased under resale agreements and securities sold under repurchase agreements attributable to this state and included in the numerator is determined by multiplying the amount described in subparagraph (A) of subdivision (1) of this subsection from such funds and such securities by a fraction, the numerator of which is the average value of federal funds sold and securities purchased under agreements to resell which are properly assigned to a regular place of business of the taxpayer within this state and the denominator of which is the average value of all such funds and such securities.

(C) The amount of interest, dividends, gains and other income from trading assets and activities, including, but not limited to, assets and activities in the matched book, in the arbitrage book and foreign currency transactions, but excluding amounts described in subparagraph (A) or (B) of this subdivision, attributable to this state and included in the numerator is determined by multiplying the amount described in subparagraph (B) of subdivision (1) of this subsection by a fraction, the numerator of which is the average value of such trading assets which are properly assigned to a regular place of business of the taxpayer within this state and the denominator of which is the average value of all such assets.

(D) For purposes of this subdivision, the average value of property owned by the taxpayer is computed on an annual basis by adding the value of the property on the first day of the income year and the value on the last day of the income year and dividing the sum by two. If averaging on this basis does not properly reflect average value, the commissioner may require averaging on a more frequent basis. The taxpayer may elect to average on a more frequent basis. When averaging on a more frequent basis is required by the commissioner or is elected by the taxpayer, the same method of valuation must be used consistently by the taxpayer with respect to property within and without this state and on all subsequent returns unless the taxpayer receives prior permission from the commissioner or the commissioner requires a different method of determining average value.

(3) In lieu of using the method set forth in subdivision (2) of this subsection, the taxpayer may elect, or the commissioner may require in order to fairly represent the business activity of the taxpayer in this state, the use of the method set forth in this subdivision.

(B) The amount of interest from federal funds sold and purchased and from securities purchased under resale agreements and securities sold under repurchase agreements attributable to this state and included in the numerator is determined by multiplying the amount described in subparagraph (A) of subdivision (1) of this subsection from such funds and such securities by a fraction, the numerator of which is the gross income from such funds and such securities which are properly assigned to a regular place of business of the taxpayer within this state and the denominator of which is the gross income from all such funds and securities.

(C) The amount of interest, dividends, gains and other income from trading assets and activities, including, but not limited to, assets and activities in the matched book, in the arbitrage book and foreign currency transactions, but excluding amounts described in subparagraph (A) or (B) of this subdivision, attributable to this state and included in the numerator is determined by multiplying the amount described in subparagraph (B) of subdivision (1) of this subsection by a fraction, the numerator of which is the gross income from such trading assets and activities which are properly assigned to a regular place of business of the taxpayer within this state and the denominator of which is the gross income from all such assets and activities.

(4) If the taxpayer elects or is required by the commissioner to use the method set forth in subdivision (3) of this subsection, it shall use this method on all subsequent returns unless the taxpayer receives prior permission from the commissioner to use, or the commissioner requires a different method.

(5) The taxpayer shall have the burden of proving that an investment asset or activity or trading asset or activity was properly assigned to a regular place of business outside of this state by demonstrating that the day-to-day decisions regarding the asset or activity occurred at a regular place of business outside this state. Where the day-to-day decisions regarding an investment asset or activity or trading asset or activity occur at more than one regular place of business and one such regular place of business is in this state and one such regular place of business is outside this state, such asset or activity shall be considered to be located at the regular place of business of the taxpayer where the investment or trading policies or guidelines with respect to the asset or activity are established. Unless the taxpayer demonstrates to the contrary, such policies and guidelines shall be presumed to be established at the commercial domicile of the taxpayer.

(j) (1) The numerator of the receipts factor includes receipts received for management, distribution and administrative services performed on behalf of an investment entity in an amount equal to the product of such receipts for the income year multiplied by a fraction (A) the numerator of which shall be the average of (i) the fair market value of the interests in the investment entity issued and outstanding on the first day of such investment entity’s taxable year for federal income tax purposes, which ends within or at the same time as the income year of the financial service company, that are owned by investors in such investment entity if the billing address of such investors is in this state, and (ii) the fair market value of the interests in the investment entity issued and outstanding on the last day of such investment entity’s taxable year for federal income tax purposes, which ends within or at the same time as the income year of the financial service company, that are owned by investors in such investment entity if the billing address of such investors is in this state; and (B) the denominator of which shall be the average of the fair market value of the interests in the investment entity issued and outstanding that are owned by investors in such investment entity on such dates.

(2) The numerator of the receipts factor includes receipts received for management, distribution and administrative services performed on behalf of a pension fund or retirement account in an amount equal to the product of such receipts for the income year multiplied by a fraction (A) the numerator of which shall be the average of (i) the number of participants with an interest in the pension fund or retirement account on the first day of the pension fund or retirement account taxable year, for federal income tax purposes, which ends within or at the same time as the income year of the financial service company, whose billing address is in this state, and (ii) the number of participants with an interest in the pension fund or retirement account on the last day of the pension fund or retirement account taxable year, for federal income tax purposes, which ends within or at the same time as the income year of the financial service company, whose billing address is in this state; and (B) the denominator of which shall be the total number of participants with an interest in the pension fund or retirement account on such dates. In lieu of using the billing addresses of the participants with an interest in the pension fund or retirement account as provided in this subdivision, the taxpayer may elect to determine receipts in the manner provided for in this subsection based upon the average of the fair market value of funds under management in each income year allocated to the commercial domicile of the sponsor of the pension fund or retirement account and, where there is no sponsor for a particular pension fund or retirement account, the billing address of the participant. The election, if made by the taxpayer, shall be irrevocable for, and applicable for, five successive income years and shall be applicable to all receipts from the rendering of management, distribution or administrative services performed for any pension fund or retirement account.
