(B) The annual financial institution report determines the value of the issued and outstanding shares of stock of the taxpayer, and is the base or measure of the franchise tax liability. Such determination shall be made as of the date shown by the report to have been the beginning of the financial institution's annual accounting period that includes the first day of January of the tax year. For purposes of this section, division (A) of section 5733.05, and division (D) of section 5733.06 of the Revised Code, the value of the issued and outstanding shares of stock of the financial institution shall include the total value, as shown by the books of the financial institution, of its capital, surplus, whether earned or unearned, undivided profits, and reserves, but exclusive of:

1. (1) Reserves for accounts receivable, depreciation, depletion, and any other valuation reserves with respect to specific assets;

5. (5) A portion of the value of the issued and outstanding shares of stock of such financial institution equal to the amount obtained by multiplying such value by the quotient obtained by:

   1. (a) Dividing (1) the amount of the financial institution's assets, as shown on its books, represented by investments in the capital stock and indebtedness of public utilities, except electric companies and combined companies, and, for tax years 2005 and thereafter, telephone companies, of which at least eighty per cent of the utility's issued and outstanding common stock is owned by the financial institution by (2) the total assets of such financial institution as shown on its books;
   2. (b) Dividing (1) the amount of the financial institution's assets, as shown on its books, represented by investments in the capital stock and indebtedness of insurance companies of which at least eighty per cent of the insurance company's issued and outstanding common stock is owned by the financial institution by (2) the total assets of such financial institution as shown on its books;
   3. (c) Dividing (1) the amount of the financial institution's assets, as shown on its books, represented by investments in the capital stock and indebtedness of other financial institutions of which at least twenty-five per cent of the other financial institution's issued and outstanding common stock is owned by the financial institution by (2) the total assets of the financial institution as shown on its books. Division (B)(5)(c) of this section applies only with respect to such other financial institutions that for the tax year immediately following the taxpayer's taxable year will pay the tax imposed by division (D) of section 5733.06 of the Revised Code.
6. (6) Land that has been determined pursuant to section 5713.31 of the Revised Code by the county auditor of the county in which the land is located to be devoted exclusively to agricultural use as of the first Monday of June in the financial institution's taxable year.
7. (7) Property within this state used exclusively during the taxable year for qualified research as defined in section 5733.05 of the Revised Code.

(D) A financial institution shall calculate the property factor as follows:

1. (1) The property factor is a fraction, the numerator of which is the average value of real property and tangible personal property rented to the taxpayer that is located or used within this state during the taxable year, the average value of real and tangible personal property owned by the taxpayer that is located or used within this state during the taxable year, and the average value of the taxpayer's loans and credit card receivables that are located within this state during the taxable year; and the denominator of which is the average value of all such property located or used within and without this state during the taxable year.

2. (2)

   1. (a) The value of real property and tangible personal property owned by the taxpayer is the original cost or other basis of such property for federal income tax purposes without regard to depletion, depreciation, or amortization.
   2. (b) Loans are valued at their outstanding principal balance, without regard to any reserve for bad debts. If a loan is charged-off in whole or in part for federal income tax purposes, the portion of the loan charged-off is not outstanding. A specifically allocated reserve established pursuant to financial accounting guidelines which is treated as charged-off for federal income tax purposes shall be treated as charged-off for purposes of this section.
   3. (c) Credit card receivables are valued at their outstanding principal balance, without regard to any reserve for bad debts. If a credit card receivable is charged-off in whole or in part for federal income tax purposes, the portion of the receivable charged-off is not outstanding.
3. (3) 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 taxable year and the value on the last day of the taxable year and dividing the sum by two. If averaging on this basis does not properly reflect average value, the tax 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 tax 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 tax commissioner or the tax commissioner requires a different method of determining value.

4. (4)

   1. (a) The average value of real property and tangible personal property that the taxpayer has rented from another and is not treated as property owned by the taxpayer for federal income tax purposes, shall be determined annually by multiplying the gross rents payable during the taxable year by eight.
   2. (b) Where the use of the general method described in division (D)(4)(a) of this section results in inaccurate valuations of rented property, any other method which properly reflects the value may be adopted by the tax commissioner or by the taxpayer when approved in writing by the tax commissioner. Once approved, such other method of valuation must be used on all subsequent returns unless the taxpayer receives prior approval from the tax commissioner or the tax commissioner requires a different method of valuation.

5. (5)

   1. (a) Except as described in division (D)(5)(b) of this section, real property and tangible personal property owned by or rented to the taxpayer is considered to be located within this state if it is physically located, situated, or used within this state.
   2. (b) Transportation property is included in the numerator of the property factor to the extent that the property is used in this state. The extent an aircraft will be deemed to be used in this state and the amount of value that is to be included in the numerator of this state's property factor is determined by multiplying the average value of the aircraft by a fraction, the numerator of which is the number of landings of the aircraft in this state and the denominator of which is the total number of landings of the aircraft everywhere. If the extent of the use of any transportation property within this state cannot be determined, then the property will be deemed to be used wholly in the state in which the property has its principal base of operations. A motor vehicle will be deemed to be used wholly in the state in which it is registered.

6. (6)

   1. (a)

      1. (i) A loan, other than a loan or advance described in division (D)(6)(d) of this section, is considered to be located within this state if it is properly assigned to a regular place of business of the taxpayer within this state.

      2. (ii) A loan is properly assigned to the regular place of business with which it has a preponderance of substantive contacts. A loan assigned by the taxpayer to a regular place of business without the state shall be presumed to have been properly assigned if:

         1. (I) The taxpayer has assigned, in the regular course of its business, such loan on its records to a regular place of business consistent with federal or state regulatory requirements;
         2. (II) Such assignment on its records is based upon substantive contacts of the load to such regular place of business; and
         3. (III) The taxpayer uses the records reflecting assignment of loans for the filing of all state and local tax returns for which an assignment of loans to a regular place of business is required.
      3. (iii) The presumption of proper assignment of a loan provided in division (D)(6)(a)(ii) of this section may be rebutted upon a showing by the tax commissioner, supported by a preponderance of the evidence, that the preponderance of substantive contacts regarding such loan did not occur at the regular place of business to which it was assigned on the taxpayer's records. When such presumption has been rebutted, the loan shall then be located within this state if (1) the taxpayer had a regular place of business within this state at the time the loan was made; and (2) the taxpayer fails to show, by a preponderance of the evidence, that the preponderance of substantive contacts regarding such loan did not occur within this state.
   2. (b) In the case of a loan which is assigned by the taxpayer to a place without this state which is not a regular place of business, it shall be presumed, subject to rebuttal by the taxpayer on a showing supported by the preponderance of evidence, that the preponderance of substantive contacts regarding the loan occurred within this state if, at the time the loan was made the taxpayer's commercial domicile was within this state.

   3. (c) To determine the state in which the preponderance of substantive contacts relating to a loan have occurred, the facts and circumstances regarding the loan at issue shall be reviewed on a case-by-case basis and consideration shall be given to such activities as the solicitation, investigation, negotiation, approval, and administration of the loan. The terms "solicitation," "investigation," "negotiation," "approval," and "administration" are defined as follows:

      1. (i) "Solicitation" is either active or passive. Active solicitation occurs when an employee of the taxpayer initiates the contact with the customer. Such activity is located at the regular place of business which the taxpayer's employee is regularly connected with or working out of, regardless of where the services of such employee were actually performed. Passive solicitation occurs when the customer initiates the contact with the taxpayer. If the customer's initial contact was not at a regular place of business of the taxpayer, the regular place of business, if any, where the passive solicitation occurred is determined by the facts in each case.
      2. (ii) "Investigation" is the procedure whereby employees of the taxpayer determine the creditworthiness of the customer as well as the degree of risk involved in making a particular agreement. Such activity is located at the regular place of business which the taxpayer's employees are regularly connected with or working out of, regardless of where the services of such employees were actually performed.
      3. (iii) Negotiation is the procedure whereby employees of the taxpayer and its customer determine the terms of the agreement, such as the amount, duration, interest rate, frequency of repayment, currency denomination, and security required. Such activity is located at the regular place of business to which the taxpayer's employees are regularly connected or working from, regardless of where the services of such employees were actually performed.
      4. (iv) "Approval" is the procedure whereby employees or the board of directors of the taxpayer make the final determination whether to enter into the agreement. Such activity is located at the regular place of business to which the taxpayer's employees are regularly connected or working from, regardless of where the services of such employees were actually performed. If the board of directors makes the final determination, such activity is located at the commercial domicile of the taxpayer.
      5. (v) "Administration" is the process of managing the account. This process includes bookkeeping, collecting the payments, corresponding with the customer, reporting to management regarding the status of the agreement, and proceeding against the borrower or the security interest if the borrower is in default. Such activity is located at the regular place of business that oversees this activity.
   4. (d) A loan or advance to a subsidiary corporation at least fifty-one per cent of whose common stock is owned by the financial institution shall be allocated in and out of the state by the application of a ratio whose numerator is the sum of the net book value of the subsidiary's real property owned in this state and the subsidiary's tangible personal property owned in this state and whose denominator is the sum of the subsidiary's real property owned wherever located and the subsidiary's tangible personal property owned wherever located. For purposes of calculating this ratio, the taxpayer shall determine net book value in accordance with generally accepted accounting principles. If the subsidiary corporation owns at least fifty-one per cent of the common stock of another corporation, the ratio shall be calculated by including the other corporation's real property and tangible personal property. The calculation of the ratio applies with respect to all lower-tiered subsidiaries, provided that the immediate parent corporation of the subsidiary owns at least fifty-one per cent of the common stock of that subsidiary.
7. (7) For purposes of determining the location of credit card receivables, credit card receivables shall be treated as loans and shall be subject to division (D)(6) of this section.
8. (8) A loan that has been properly assigned to a state shall, absent any change of material fact, remain assigned to that state for the length of the original term of the loan. Thereafter, the loan may be properly assigned to another state if the loan has a preponderance of substantive contact to a regular place of business there.

(E) A financial institution shall calculate the payroll factor as follows:

1. (1) The payroll factor is a fraction, the numerator of which is the total amount paid in this state during the taxable year by the taxpayer for compensation, and the denominator of which is the total compensation paid both within and without this state during the taxable year.

2. (2) Compensation is paid in this state if any one of the following tests, applied consecutively, is met:

   1. (a) The employee's services are performed entirely within this state.
   2. (b) The employee's services are performed both within and without this state, but the service performed without this state is incidental to the employee's service within this state. The term "incidental" means any service which is temporary or transitory in nature, or which is rendered in connection with an isolated transaction.

   3. (c) The employee's services are performed both within and without this state, and:

      1. (i) The employee's principal base of operations is within this state; or
      2. (ii) There is no principal base of operations in any state in which some part of the services are performed, but the place from which the services are directed or controlled is in this state; or
      3. (iii) The principal base of operations and the place from which the services are directed or controlled are not in any state in which some part of the service is performed but the employee's residence is in this state.

(F) A financial institution shall calculate the sales factor as follows:

1. (1) The sales factor is a fraction, the numerator of which is the receipts of the taxpayer in this state during the taxable year and the denominator of which is the receipts of the taxpayer within and without this state during the taxable 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. (2) The numerator of the sales factor includes receipts from the lease or rental of real property owned by the taxpayer if the property is located within this state, or receipts from the sublease of real property if the property is located within this state.

3. (3)

   1. (a) Except as described in division (F)(3)(b) of this section the numerator of the sales factor includes receipts from the lease or rental of tangible personal property owned by the taxpayer if the property is located within this state when it is first placed in service by the lessee.
   2. (b) Receipts from the lease or rental of transportation property owned by the taxpayer are included in the numerator of the sales factor to the extent that the property is used in this state. The extent an aircraft will be deemed to be used in this state and the amount of receipts that is to be included in the numerator of this state's sales factor is determined by multiplying all the receipts from the lease or rental of the aircraft by a fraction, the numerator of which is the number of landings of the aircraft in this state and the denominator of which is the total number of landings of the aircraft. If the extent of the use of any transportation property within this state cannot be determined, then the property will be deemed to be used wholly in the state in which the property has its principal base of operations. A motor vehicle will be deemed to be used wholly in the state in which it is registered.

4. (4)

   1. (a) The numerator of the sales factor includes interest and fees or penalties in the nature of interest from loans secured by real property if the property is located within this state. If the property is located both within this state and one or more other states, the receipts described in this paragraph are included in the numerator of the sales 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, then the receipts described in this paragraph shall be included in the numerator of the sales factor if the borrower is located in this state.
   2. (b) 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 any and all subsequent substitutions of collateral shall be disregarded.
5. (5) The numerator of the sales factor includes interest and fees or penalties in the nature of interest from loans not secured by real property if the borrower is located in this state.

6. (6) The numerator of the sales factor includes net gains from the sale of loans. Net gains from the sale of loans includes income recorded under the coupon stripping rules of section 1286 of the Internal Revenue Code.

   1. (a) 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 sales factor pursuant to division (F)(4) 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. (b) 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 sales factor pursuant to division (F)(5) 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.
7. (7) The numerator of the sales factor includes interest and fees or penalties in the nature of interest from credit card receivables and receipts from fees charged to card holders, such as annual fees, if the billing address of the card holder is in this state.
8. (8) The numerator of the sales factor includes net gains, but not less than zero, from the sale of credit card receivables multiplied by a fraction, the numerator of which is the amount included in the numerator of the sales factor pursuant to division (F)(7) of this section and the denominator of which is the taxpayer's total amount of interest and fees or penalties in the nature of interest from credit card receivables and fees charged to card holders.
9. (9) The numerator of the sales factor includes all credit card issuer's reimbursement fees multiplied by a fraction, the numerator of which is the amount included in the numerator of the sales factor pursuant to division (F)(7) of this section and the denominator of which is the taxpayer's total amount of interest and fees or penalties in the nature of interest from credit card receivables and fees charged to card holders.
10. (10) The numerator of the sales factor includes receipts from merchant discount if the commercial domicile of the merchant is in this state. Such receipts shall be computed net of any card holder charge backs, but shall not be reduced by any interchange transaction fees or by any issuer's reimbursement fees paid to another for charges made by its card holders.

11. (11)

    1. (a)

       1. (i) The numerator of the sales 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 sales factor pursuant to division (F)(4) 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. (ii) The numerator of the sales 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 sales factor pursuant to division (F)(5) 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.
    2. (b) 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 sales factor shall include such fees if the borrower is located in this state.
12. (12) The numerator of the sales factor includes receipts from services not otherwise apportioned under this section if the service is performed in this state. If the service is performed both within and without this state, the numerator of the sales factor includes receipts from services not otherwise apportioned under this section, if a greater proportion of the income-producing activity is performed in this state based on cost of performance.

13. (13)

    1. (a) Interest, dividends, net gains, but not less than zero, and other income from investment assets and activities and from trading assets and activities shall be included in the sales factor. 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 divisions (F)(13)(a)(i) and (ii) of this section, the sales factor shall include the amounts described in such divisions.

       1. (i) The sales 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.
       2. (ii) The sales factor shall include the amount by which 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, exceed amounts paid in lieu of interest, amounts paid in lieu of dividends, and losses from such assets and activities.

    2. (b) The numerator of the sales factor includes interest, dividends, net gains, but not less than zero, and other income from investment assets and activities and from trading assets and activities described in division (F)(13)(a) of this section that are attributable to this state.

       2. (ii) 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 division (F)(13)(a)(i) of this section 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.
       3.
