An except from the announcement that seems pretty clear to me
"You will be asked to agree to transfer your contract to Sekisui House and will be required to pay to them all remaining funds due under the original ProCorp contract. SICorp will pay the agreed shortfall to Sekisui House. No homeowner offered this method of settlement will need to pay any more than they would have paid to Procorp. Sekisui House will also rectify defects already identied or discovered on recommencement of construction. "
