Capability variation.
(3) Capability variation. A capability variation occurs when, in a CSA in which interests in cost shared intangibles are divided as described in paragraph (b)(4)(iv) of this section, the controlled participants' division of interests or their relative capabilities or capacities to benefit from the cost shared intangibles are materially altered. For purposes of paragraph (a)(3)(ii) of this section, a capability variation is considered to be a controlled transfer of interests in cost shared intangibles, in which any controlled participant whose RAB share decreases as a result of the capability variation is a transferor, and any controlled participant whose RAB share thus increases is the transferee of the interests in cost shared intangibles.
