BUZZ-Persimmon: falls after chairman & director quit over incentive scheme

** Housebuilder Persimmon down 1.4 pct after its chairman and a senior independent director quit for their role in a lucrative management incentive scheme

** Statement says the long term incentive plan, criticised for paying out hundreds of millions of pounds to directors, should have included a cap

** "This scheme has been far more successful than the company or observers expected, and has created controversy through the amounts generated for management across the group," say analysts at Liberum

** Broker says timing of departure may be explained by the fact 40 pct of options in the plan are exercisable on December 31

** Liberum says there are 24 mln shares outstanding in the LTIP with an average exercise price of 1977p, suggesting pre-tax upside of around £162m
