#bring off

To bring off something (or bring something off) is to succeed in achieving something difficult.
Examples of use:
a) Your new Manager has promised to increase turnover by 40%. Do you really think he can bring it off?
b) They successfully brought off their plans to relocate the company to Malaysia.
c) We need to increase our profits by 20% by April 2012. I’m not sure we can bring it off.
