After hearing the allegations and proofs and the arguments thereon of the respective parties, the court or the judge before whom such hearing is had shall render a decision, stating how much of the debt of the said city shall have been incurred and the proceeds thereof invested in any public improvements of any character which shall be yielding to the said city an annual current net revenue, how much of such debt shall have been so incurred and the proceeds thereof so invested in each of such public improvements, the amount of the gross revenue and the net revenue from each such public improvement during the year immediately preceding the time of such ascertainment, with such particulars as shall show how the computation of the net revenue is made, the average rate of interest and sinking-fund charges payable upon the indebtedness incurred by the said city for each such improvement, and the capitalization of the principal amount which would yield such annual current net revenue at the average rate of interest and sinking-fund charges payable upon the indebtedness incurred by the said city therefor; and shall make an order fixing the total amount which for that reason the said city may exclude from the calculation and deduct from its debt in ascertaining its borrowing capacity. Should such a hearing be before a judge of the said court, exceptions to his findings and decision may be filed by any party in interest who shall have appeared, as aforesaid, within ten (10) days after such decision shall have been rendered and notice of said findings and decision shall have been given to all parties by the prothonotary of the court, and the said exceptions shall be heard and disposed of by the court in banc, in the same manner, and subject to the same rules, as govern the hearing of exceptions upon trials in equity. If no exceptions be filed within ten (10) days to the findings and decision of such judge, they shall be final and conclusive. Upon the making of such order by the court or by a judge thereof, if no exceptions be filed to his decision, the amount so ascertained shall thereupon be wholly excluded in determining the power of such city to become otherwise indebted.
