§12A-9-303.
   
   (1) A security interest is perfected when it has attached and when all
   of the applicable steps required for perfection have been taken. Such
   steps are specified in Sections 9-302, 9-304, 9-305 and 9-306. If such
   steps are taken before the security interest attaches, it is perfected
   at the time when it attaches.
   
   (2) If a security interest is originally perfected in any way
   permitted under this article and is subsequently perfected in some
   other way under this article, without an intermediate period when it
   was unperfected, the security interest shall be deemed to be perfected
   continuously for the purposes of this article.
