127.15. For the purposes of this division,(a) where any person or partnership has a right under a contract or otherwise, either immediately or in the future and either absolutely or contingently, to, or to acquire, shares of the capital stock of a corporation, that person or partnership is deemed to own those shares if it can reasonably be considered that the principal purpose for the existence of the right is to avoid or reduce the amount of income that a corporation would otherwise be required to include in computing its income for a taxation year under section 127.6; and
(b) where any person or partnership acquires or disposes of shares of the capital stock of a corporation, either directly or indirectly, and it can reasonably be considered that the principal purpose for the acquisition or disposition of the shares is to avoid or reduce the amount of income that a corporation would otherwise be required to include in computing its income for a taxation year under section 127.6, those shares are deemed not to have been acquired or disposed of, as the case may be, and where the shares were unissued by the corporation immediately before the acquisition, those shares are deemed not to have been issued.
