      Sec. 12-218. Apportionment of net income. (a) Any taxpayer which is taxable 
both within and without this state shall apportion its net income as provided in this 
section. For purposes of apportionment of income under this section, a taxpayer is taxable in another state if in such state such taxpayer conducts business and is subject to 
a net income tax, a franchise tax for the privilege of doing business, or a corporate stock 
tax, or if such state has jurisdiction to subject such taxpayer to such a tax, regardless of 
whether such state does, in fact, impose such a tax.
      (b) The net income of the taxpayer, when derived from business other than the 
manufacture, sale or use of tangible personal or real property, shall be apportioned within 
and without the state by means of an apportionment fraction, the numerator of which 
shall represent the gross receipts from business carried on within Connecticut and the 
denominator shall represent the gross receipts from business carried on everywhere, 
except that any gross receipts attributable to an international banking facility, as defined 
in section 12-217, shall not be included in the numerator or the denominator. Gross 
receipts as used in this subsection shall have the same meaning as used in subdivision 
(3) of subsection (c) of this section.
      (c) Except as otherwise provided in subsection (k) or (l) of this section, the net 
income of the taxpayer when derived from the manufacture, sale or use of tangible 
personal or real property, shall be apportioned within and without the state by means 
of an apportionment fraction, to be computed as the sum of the property factor, the 
payroll factor and twice the receipts factor, divided by four. (1) The first of these fractions, the property factor, shall represent that part of the average monthly net book value 
of the total tangible property held and owned by the taxpayer during the income year 
which is held within the state, without deduction on account of any encumbrance thereon, 
and the value of tangible property rented to the taxpayer computed by multiplying the 
gross rents payable during the income year or period by eight. For the purpose of this 
section, gross rents shall be the actual sum of money or other consideration payable, 
directly or indirectly, by the taxpayer or for its benefit for the use or possession of the 
property, excluding royalties, but including interest, taxes, insurance, repairs or any 
other amount required to be paid by the terms of a lease or other arrangement and a 
proportionate part of the cost of any improvement to the real property made by or on 
behalf of the taxpayer which reverts to the owner or lessor upon termination of a lease 
or other arrangement, based on the unexpired term of the lease commencing with the 
date the improvement is completed, provided, where a building is erected on leased land 
by or on behalf of the taxpayer, the value of the land is determined by multiplying the 
gross rent by eight, and the value of the building is determined in the same manner as 
if owned by the taxpayer. (2) The second fraction, the payroll factor, shall represent the 
part of the total wages, salaries and other compensation to employees paid by the taxpayer during the income year which was paid in this state, excluding any such wages, 
salaries or other compensation attributable to the production of gross income of an 
international banking facility as defined in section 12-217. Compensation is paid in this 
state if (A) the individual's service is performed entirely within the state; or (B) the 
individual's service is performed both within and without the state, but the service performed without the state is incidental to the individual's service within the state; or (C) 
some of the service is performed in the state and (i) the base of operations or, if there 
is no base of operations, the place from which the service is directed or controlled is in 
the state, or (ii) the base of operations or the place from which the service is directed 
or controlled is not in any state in which some part of the service is performed, but the 
individual's residence is in this state. (3) The third fraction, the receipts factor, shall 
represent the part of the taxpayer's gross receipts from sales or other sources during the 
income year, computed according to the method of accounting used in the computation 
of its entire net income, which is assignable to the state, and excluding any gross receipts 
attributable to an international banking facility as defined in section 12-217, but including receipts from sales of tangible property if the property is delivered or shipped to a 
purchaser within this state, other than a company which qualifies as a Domestic International Sales Corporation (DISC) as defined in Section 992 of the Internal Revenue Code 
of 1986, or any subsequent corresponding internal revenue code of the United States, 
as from time to time amended, and as to which a valid election under Subsection (b) of 
said Section 992 to be treated as a DISC is effective, regardless of the f.o.b. point or 
other conditions of the sale, receipts from services performed within the state, rentals 
and royalties from properties situated within the state, royalties from the use of patents 
or copyrights within the state, interest managed or controlled within the state, net gains 
from the sale or other disposition of intangible assets managed or controlled within the 
state, net gains from the sale or other disposition of tangible assets situated within the 
state and all other receipts earned within the state.
      (d) Any motor bus company which is taxable both within and without this state 
shall apportion its net income derived from carrying of passengers for hire by means of 
an apportionment fraction, the numerator of which shall represent the total number of 
miles operated within this state and the denominator of which shall represent the total 
number of miles operated everywhere, but income derived by motor bus companies 
from sources other than the carrying of passengers for hire shall be apportioned as herein 
otherwise provided.
      (e) Any motor carrier which transports property for hire and which is taxable both 
within and without this state shall apportion its net income derived from carrying of 
property for hire by means of an apportionment fraction, the numerator of which shall 
represent the total number of miles operated within this state and the denominator of 
which shall represent the total number of miles operated everywhere, but income derived 
by motor carriers from sources other than the carrying of property for hire shall be 
apportioned as herein otherwise provided.

first day of such regulated investment company's taxable year, for federal income tax 
purposes, which ends within or at the same time as the taxable year of the taxpayer, that 
are owned by shareholders of such regulated investment company then domiciled in 
this state and (ii) the number of shares on the last day of such regulated investment 
company's taxable year, for federal income tax purposes, which ends within or at the 
same time as the taxable year of the taxpayer, that are owned by shareholders of such

supported by such separate account. An election made under this subparagraph shall 
apply to all shareholders that are insurance companies and shall be irrevocable for, 
and applicable for, five successive income years. In any year that such an election is
