Caiff y gronfa ei gweinyddu gan Busnes Cymru a bydd yn cefnogi busnesau â'r costau adfer cychwynnol na fydd yswiriant yn talu amdanynt, a hefyd yn helpu â chost rhentu eiddo dros dro a chadw staff.
The fund will be administered by Business Wales and will support businesses with the immediate costs of recovery not covered by insurance, and to help meet the cost of renting alternative space and retaining staff.
