In conformity with the Transparency Directive's transitional provision 6 we would

like to notify the market of the following: 

The total number of ordinary shares of 0.1p of CSR plc in issue at the date of 

this notice is 132,772,856 with each share carrying one right to vote. 

Therefore the total number of voting rights in CSR plc at the date of this notice 

is 132,772,856. 

There are no shares held in treasury. 

The above figure (132,772,856) may be used by shareholders as the denominator

Transparency Rules.
