Plan rules authorizing asset transfers consistent with the requirements of section 1412(c)(3) of this title shall be considered to satisfy the requirements of this subsection.

(b) Exemption of de minimis transfers
The corporation shall prescribe regulations which exempt de minimis transfers of assets from the requirements of this part.

(c) Written reciprocity agreements
This part shall not apply to transfers of assets pursuant to written reciprocity agreements, except to the extent provided in regulations prescribed by the corporation.
