The purpose of this section is to ensure that an appropriate level of protection is provided for those assets over which a client gives a firm certain rights. The arrangements covered by this section are those under which the firm is given a right to use the asset, and the firm treats the asset as if legal title and associated rights to that asset had been transferred to the firm subject only to an obligation to return equivalent assets to the client upon satisfaction of the client's obligation to the firm. The rights covered in this section do not include those arrangements by which the firm has only a bare security interest in the client's asset (in which case the custody rules or client money rules apply).
This section recognises the need to apply a differing level of regulatory protection to the assets which form the basis of the two different types of arrangement described in CASS 3.1.5 G. Under the bare security interest arrangement, the asset continues to belong to the client until the firm's right to realise that asset crystallises (that is, on the client's default). But under a "right to use arrangement", the client has transferred to the firm the legal title and associated rights to the asset, so that when the firm exercises its right to treat the asset as its own, the asset ceases to belong to the client and in effect becomes the firm's asset and is no longer in need of the full range of client asset protection. The firm may exercise its right to treat the asset as its own by, for example, clearly so identifying the asset in its own books and records.
