Servicing Strip

A security created by the stream of cash flows that result from the servicing fee on a mortgage. Servicing strips trade in a secondary market much like mortgage-backed securities do; the seller of the servicing strip has the ability to service the mortgage. 



|||Like mortgage-backed securities, servicing strips have an embedded call option that may be exercised by the borrower. When a borrower pays off the mortgage - either through refinancing or by moving to a new residence - the serving strip goes away. 

The embedded option must be considered when performing a valuation of a servicing strip.
