61 I reject his submission. I am satisfied that in this case there was, on the material presented to the plaintiff before it agreed to make the loan, a risk - but not a high risk - that the defendants would not repay the loan by the stipulated date 9 December 1997. The plaintiff has the personal covenant of the defendants to repay the loan in both Deed of Loan and mortgage (although the mortgage provided for repayment on 17 December 1997). The third mortgage was registered and it provided some security for repayment of the debt. If the plaintiff attempted to exercise its power of sale under the mortgage, at best it would be able to sell the defendants' equity of redemption and any purchaser would buy subject to the prior first and second mortgages and accepting the defendants' liability under the mortgages. Whether, on attempted sale by the plaintiff as third mortgagee, any buyer would have been found, appears now to be doubtful. I am really not in any position to comment further and I say simply the third mortgage provided some security the quality of which is not known. Because the plaintiff has not attempted to exercise its power of sale but has instead sued on the personal covenant it may be inferred now that the value of the security is doubtful. Of course the ballooning debt (see Exhibit 2) appears to have completely extinguished the value of the equity - assuming that equity to be still about $450,000. Given the size of the debt the value of the security now is irrelevant. In my view, I should fix a rate of interest having regard to the fact that the plaintiff did obtain a registered third mortgage in respect of a loan of $70,588 for one month where the equity of redemption was valued at some $450,000 about one year earlier and having regard to the further facts the last sentence of which appear in paragraph 60 ante. The debt in Exhibit 2 was not initially wholly unsecured - it appears that at present it may be partly secured but very largely unsecured. In the particular circumstances of this case, where, as I have said the defendant was initially prepared to pay interest at 15 per cent per month for the one month loan, and where the terms of the loan as to repayment and interest were explained by their solicitor to them, quite independently of the plaintiff, I see no reason why the interest on the unpaid principal should not be greater and considerably greater than the 10 per cent simple interest for which Mr Stone contends.
