43 A second Calderbank offer was made on behalf of all the beneficiaries, including the second defendant, by the solicitors for the third defendant on 21 August 2013. Again by correspondence, without prejudice save as to costs, the solicitors for the third defendant wrote to the solicitors for the plaintiff on behalf of the second to sixth defendants, making an offer in full and final settlement of the plaintiff's claim. The offer was that all beneficiaries proposed to allow the plaintiff to be relieved from his debts due to the estate which, at that date, totalled $419,037.32. The details of the composition of that sum were set out and the variation from figures earlier mentioned is accounted for by the amount of interest which had accrued to that date. The letter pointed out that the net value of the balance of the estate was then approximately $1,200,000, so that if this were to be distributed to the residuary beneficiaries then, subject to tax and other expenses, each of the second and third defendants would receive approximately $400,000 and the fourth, fifth and sixth defendants would share that amount between them. The letter went on to assert that the plaintiff had already had significantly more benefit from the estate and his parents than any of the defendants would receive and that while they accepted that the plaintiff's financial position was dire, it did not appear that that could be rectified by any likely outcome of the present litigation. The offer concluded by referring to Calderbank v Calderbank and stated that the defendants would refer the court to the letter on the question of costs generally and, in particular, in support of a submission that the plaintiff pay the costs incurred by the defendants on an indemnity basis from the date of the letter. The offer was to expire on 6 September 2013 - that is, two weeks later. There was no response by or on behalf of the plaintiff to that proposal and it therefore lapsed once the time for acceptance had passed.
