All Finance Ltd is providing a line of credit $500,000 to Solar TradersPty Ltd and is looking to register an appropriate security interest.  Solar has Cash at Bank ($123,450), Trading Stock ($392,100) and owns the premises from which it operates ($1,250,000).

Solar has mortgaged this property with another bank (on which $450,000 is owed to the other bank).

It is also owed a sum of funds from Debtors during the course of trading of which 80% is owed within 60 days or less of invoicing.

Discuss the types of security interest that All Finance would seek to register to secure the advance of funds.
