(c) the outstanding balance of a contract                 or agreement described in provisions (a) or (b) of this item (i).
A customer receivable need not provide for             payment of interest on deferred payments.  A sales finance company may purchase a customer receivable from, or make a loan secured by a customer receivable to, the seller in the original transaction or to a person who purchased the customer receivable directly or indirectly from that seller.
(ii) A corporation meeting each of the             following criteria:
(a) the corporation must be a member of                 an "affiliated group" within the meaning of Section 1504(a) of the Internal Revenue Code, determined without regard to Section 1504(b) of the Internal Revenue Code;
(b) more than 50% of the gross income of                 the corporation for the taxable year must be interest income derived from qualifying loans.  A "qualifying loan" is a loan made to a member of the corporation's affiliated group that originates customer receivables (within the meaning of item (i)) or to whom customer receivables originated by a member of the affiliated group have been transferred, to the extent the average outstanding balance of loans from that corporation to members of its affiliated group during the taxable year do not exceed the limitation amount for that corporation.  The "limitation amount" for a corporation is the average outstanding balances during the taxable year of customer receivables (within the meaning of item (i)) originated by all members of the affiliated group.  If the average outstanding balances of the loans made by a corporation to members of its affiliated group exceed the limitation amount, the interest income of that corporation from qualifying loans shall be equal to its interest income from loans to members of its affiliated groups times a fraction equal to the limitation amount divided by the average outstanding balances of the loans made by that corporation to members of its affiliated group;
(c) the total of all shareholder's equity                 (including, without limitation, paid-in capital on common and preferred stock and retained earnings) of the corporation plus the total of all of its loans, advances, and other obligations payable or owed to members of its affiliated group may not exceed 20% of the total assets of the corporation at any time during the tax year; and
(d) more than 50% of all interest-bearing                 obligations of the affiliated group payable to persons outside the group determined in accordance with generally accepted accounting principles must be obligations of the corporation.
This amendatory Act of the 91st General Assembly         is declaratory of existing law.
(D) Subparagraphs (B) and (C) of this paragraph         are declaratory of existing law and apply retroactively, for all tax years beginning on or before December 31, 1996,  to all original returns, to all amended returns filed no later than 30 days after the effective date of this amendatory Act of 1996, and to all notices issued on or before the effective date of this amendatory Act of 1996 under subsection (a) of Section 903, subsection (a) of Section 904, subsection (e) of Section 909, or Section 912. A taxpayer that is a "financial organization" that engages in any transaction with an affiliate shall be a "financial organization" for all purposes of this Act.
(E) For all tax years beginning on or before         December 31, 1996, a taxpayer that falls within the definition of a "financial organization" under subparagraphs (B) or (C) of this paragraph, but who does not fall within the definition of a "financial organization" under the Proposed Regulations issued by the Department of Revenue on July 19, 1996, may irrevocably elect to apply the Proposed Regulations for all of those years as though the Proposed Regulations had been lawfully promulgated, adopted, and in effect for all of those years.  For purposes of applying subparagraphs (B) or (C) of this paragraph to all of those years, the election allowed by this subparagraph applies only to the taxpayer making the election and to those members of the taxpayer's unitary business group who are ordinarily required to apportion business income under the same subsection of Section 304 of this Act as the taxpayer making the election.  No election allowed by this subparagraph shall be made under a claim filed under subsection (d) of Section 909 more than 30 days after the effective date of this amendatory Act of 1996.
(F) Finance Leases.  For purposes of this         subsection, a finance lease shall be treated as a loan or other extension of credit, rather than as a lease, regardless of how the transaction is characterized for any other purpose, including the purposes of any regulatory agency to which the lessor is subject.  A finance lease is any transaction in the form of a lease in which the lessee is treated as the owner of the leased asset entitled to any deduction for depreciation allowed under Section 167 of the Internal Revenue Code.
(9) Fiscal year. The term "fiscal year" means an     accounting period of 12 months ending on the last day of any month other than December.
(9.5) Fixed place of business. The term "fixed place     of business" has the same meaning as that term is given in Section 864 of the Internal Revenue Code and the related Treasury regulations.
(10) Includes and including. The terms "includes" and     "including" when used in a definition contained in this Act shall not be deemed to exclude other things otherwise within the meaning of the term defined.

(27) Unitary business group.
(A) The term "unitary business group" means a         group of persons related through common ownership whose business activities are integrated with, dependent upon and contribute to each other.  The group will not include those members whose business activity outside the United States is 80% or more of any such member's total business activity; for purposes of this paragraph and clause (a)(3)(B)(ii) of Section 304, business activity within the United States shall be measured by means of the factors ordinarily applicable under subsections (a), (b), (c), (d), or (h) of Section 304 except that, in the case of members ordinarily required to apportion business income by means of the 3 factor formula of property, payroll and sales specified in subsection (a) of Section 304, including the formula as weighted in subsection (h) of Section 304, such members shall not use the sales factor in the computation and the results of the property and payroll factor computations of subsection (a) of Section 304 shall be divided by 2 (by one if either the property or payroll factor has a denominator of zero). The computation required by the preceding sentence shall, in each case, involve the division of the member's property, payroll, or revenue miles in the United States, insurance premiums on property or risk in the United States, or financial organization business income from sources within the United States, as the case may be, by the respective worldwide figures for such items.  Common ownership in the case of corporations is the direct or indirect control or ownership of more than 50% of the outstanding voting stock of the persons carrying on unitary business activity.  Unitary business activity can ordinarily be illustrated where the activities of the members are:  (1) in the same general line (such as manufacturing, wholesaling, retailing of tangible personal property, insurance, transportation or finance); or (2) are steps in a vertically structured enterprise or process (such as the steps involved in the production of natural resources, which might include exploration, mining, refining, and marketing); and, in either instance, the members are functionally integrated through the exercise of strong centralized management (where, for example, authority over such matters as purchasing, financing, tax compliance, product line, personnel, marketing and capital investment is not left to each member).
(B) In no event, for taxable years ending prior         to December 31, 2017, shall any unitary business group include members which are ordinarily required to apportion business income under different subsections of Section 304 except that for tax years ending on or after December 31, 1987 this prohibition shall not apply to a holding company that would otherwise be a member of a unitary business group with taxpayers that apportion business income under any of subsections (b), (c), (c-1), or (d) of Section 304.  If a unitary business group would, but for the preceding sentence, include members that are ordinarily required to apportion business income under different subsections of Section 304, then for each subsection of Section 304 for which there are two or more members, there shall be a separate unitary business group composed of such members.  For purposes of the preceding two sentences, a member is "ordinarily required to apportion business income" under a particular subsection of Section 304 if it would be required to use the apportionment method prescribed by such subsection except for the fact that it derives business income solely from Illinois.  As used in this paragraph, for taxable years ending before December 31, 2017, the phrase "United States" means only the 50 states and the District of Columbia, but does not include any territory or possession of the United States or any area over which the United States has asserted jurisdiction or claimed exclusive rights with respect to the exploration for or exploitation of natural resources. For taxable years ending on or after December 31, 2017, the phrase "United States", as used in this paragraph, means only the 50 states, the District of Columbia, and any area over which the United States has asserted jurisdiction or claimed exclusive rights with respect to the exploration for or exploitation of natural resources, but does not include any territory or possession of the United States.
(C) Holding companies.
(i) For purposes of this subparagraph, a             "holding company" is a corporation (other than a corporation that is a financial organization under paragraph (8) of this subsection (a) of Section 1501 because it is a bank holding company under the provisions of the Bank Holding Company Act of 1956 (12 U.S.C. 1841, et seq.) or because it is owned by a bank or a bank holding company) that owns a controlling interest in one or more other taxpayers ("controlled taxpayers"); that, during the period that includes the taxable year and the 2 immediately preceding taxable years or, if the corporation was formed during the current or immediately preceding taxable year, the taxable years in which the corporation has been in existence, derived substantially all its gross income from dividends, interest, rents, royalties, fees or other charges received from controlled taxpayers for the provision of services, and gains on the sale or other disposition of interests in controlled taxpayers or in property leased or licensed to controlled taxpayers or used by the taxpayer in providing services to controlled taxpayers; and that incurs no substantial expenses other than expenses (including interest and other costs of borrowing) incurred in connection with the acquisition and holding of interests in controlled taxpayers and in the provision of services to controlled taxpayers or in the leasing or licensing of property to controlled taxpayers.
(ii) The income of a holding company which is             a member of more than one unitary business group shall be included in each unitary business group of which it is a member on a pro rata basis, by including in each unitary business group that portion of the base income of the holding company that bears the same proportion to the total base income of the holding company as the gross receipts of the unitary business group bears to the combined gross receipts of all unitary business groups (in both cases without regard to the holding company) or on any other reasonable basis, consistently applied.
(iii) A holding company shall apportion its             business income under the subsection of Section 304 used by the other members of its unitary business group.  The apportionment factors of a holding company which would be a member of more than one unitary business group shall be included with the apportionment factors of each unitary business group of which it is a member on a pro rata basis using the same method used in clause (ii).
(iv) The provisions of this subparagraph (C)             are intended to clarify existing law.
(D) If including the base income and factors of a         holding company in more than one unitary business group under subparagraph (C) does not fairly reflect the degree of integration between the holding company and one or more of the unitary business groups, the dependence of the holding company and one or more of the unitary business groups upon each other, or the contributions between the holding company and one or more of the unitary business groups, the holding company may petition the Director, under the procedures provided under Section 304(f), for permission to include all base income and factors of the holding company only with members of a unitary business group apportioning their business income under one subsection of subsections (a), (b), (c), or (d) of Section 304.  If the petition is granted, the holding company shall be included in a unitary business group only with persons apportioning their business income under the selected subsection of Section 304 until the Director grants a petition of the holding company either to be included in more than one unitary business group under subparagraph (C) or to include its base income and factors only with members of a unitary business group apportioning their business income under a different subsection of Section 304.
(E) If the unitary business group members'         accounting periods differ, the common parent's accounting period or, if there is no common parent, the accounting period of the member that is expected to have, on a recurring basis, the greatest Illinois income tax liability must be used to determine whether to use the apportionment method provided in subsection (a) or subsection (h) of Section 304.  The prohibition against membership in a unitary business group for taxpayers ordinarily required to apportion income under different subsections of Section 304 does not apply to taxpayers required to apportion income under subsection (a) and subsection (h) of Section 304.  The provisions of this amendatory Act of 1998 apply to tax years ending on or after December 31, 1998.
(28) Subchapter S corporation.  The term "Subchapter     S corporation" means a corporation for which there is in effect an election under Section 1362 of the Internal Revenue Code, or for which there is a federal election to opt out of the provisions of the Subchapter S Revision Act of 1982 and have applied instead the prior federal Subchapter S rules as in effect on July 1, 1982.
(30) Foreign person. The term "foreign person" means     any person who is a nonresident individual who is a national or citizen of a country other than the United States and any nonindividual entity, regardless of where created or organized, whose business activity outside the United States is 80% or more of the entity's total business activity.
(b) Other definitions.
(1) Words denoting number, gender, and so forth, when     used in this Act, where not otherwise distinctly expressed or manifestly incompatible with the intent thereof:
(A) Words importing the singular include and         apply to several persons, parties or things;
(B) Words importing the plural include the         singular; and
(C) Words importing the masculine gender include         the feminine as well.

The word "company" or "association", when used in reference to a corporation, shall be deemed to embrace the words "successors and assigns of such company or association", and in like manner as if these last-named words, or words of similar import, were expressed.
(3) Other terms. Any term used in any Section of this     Act with respect to the application of, or in connection with, the provisions of any other Section of this Act shall have the same meaning as in such other Section.
