Alaska Stat. § 10.25.420

A mortgage, deed of trust, or other instrument executed by a cooperative, which affects real and personal property and which is recorded in the real property records in the city, borough, or other recording districts in which the property is located or is to be located has the same effect as if recorded, filed, or indexed as provided by law in the proper office in the city, borough, or other recording district as a mortgage of personal property. All after-acquired property of the cooperative described or referred to as being mortgaged or pledged in a mortgage, deed of trust or other instrument is subject to the lien thereof immediately upon the acquisition of such property by the cooperative, whether or not the property was in existence at the time of the execution of the mortgage, deed of trust or other instrument. Recordation of such mortgage, deed of trust or other instrument constitutes notice and has the same effect with respect to after-acquired property as it has under the laws relating to recordation of property owned by the cooperative at the time of the execution of the mortgage, deed of trust or other instrument and described in it or referred to as being mortgaged or pledged thereby. The lien of such mortgage, deed of trust or other instrument upon personal property after its recordation continues for the period of time specified in the instrument without refiling or the filing of a renewal certificate, affidavit or other supplemental information required by the laws relating to the renewal, maintenance or extension of liens upon personal property.
