Barclays Wealth is marketing the fourth product in its capital-protected Growthbuilder range. The product crosses UK tax deadlines and is thus open to its Isa tax-free savings allowance for 2010/11 and 2011/12.

Growthbuilder was first launched in February 2010 and last marketed in summer 2010, when it was able to offer annual growth potential of 6.6%. VP Lisa Chaudhuri said such products continue to appeal, since what she termed the product's 'lock-in' feature, the potential payment from its embedded digital strip, helps mitigate market timing.

The six-year Growthbuilder February 2011 Dual Isa Edition is linked to the FTSE100 and registers 6.25% growth for every year the underlying is at or above its strike level. Otherwise, no growth is registered that year.

The previous two tranches had 6.6% annual growth potential and the first tranche, marketed a year ago, 7%. The product guarantees the initial investment plus the sum of registered coupons to a maximum overall return of 137.5%.

Barclays' Growthbuilder February 2011 Dual Isa Edition will be available until 8 April. Minimum investment is £5,100.

This product is available in Recent Additions (UK).
