Section 306. Validity of pledge.
Any pledge of or grant of a security interest in revenues of the authority or personal property of an authority made by the authority shall be valid and binding from the time when the pledge is made; the revenues or other property so pledged and thereafter received by the authority shall immediately be subject to the lien of any such pledge or security interest without any physical delivery thereof or further act, and the lien of any such pledge or security interest shall be valid and binding as against all parties having claims of any kind in tort, contract or otherwise against the authority irrespective of whether such parties have notice thereof. Neither the resolution nor any other instrument of the authority by which a pledge or security interest is created need be recorded or filed to perfect such pledge or security interest.
