Why has the Farm Supplier I bought from Registered a PPSR Charge Against Me?

Farm Supply companies such as RD 1, PG Wrightson and Farmlands will often register a financing statement (eg a charge) under your name at the Personal Property Securities Register when you open an account with them.  A financing statement contains information about the security interest.  Registration of the financing will in general determine the priority of creditors if you become insolvent.  Those creditors who have registered their financing statements rank ahead of those who haven’t registered, and the order of those registered is determined by the date on which they registered their financing statement.
