million, commitments for advertising campaigns of $4.7 million, inventory purchase commitments of $6.8 million, and other unrecorded purchase commitments of $30.6 million.
Senior unsecured notes and interest payments. Our 7.0% senior unsecured notes due 2022 bear interest at a rate of 7.0% per annum and mature on April 1, 2022. Interest on the notes is payable semi-annually on April 1 and October 1 of each year and has been included in the table above.
Other debt and interest payments. On July 13, 2017, we amended our credit agreement to, among other things, expand the total capacity and extend the term of our term loans and revolving loans. Refer to Note 8 for additional information.
At September 30, 2017, the term loans of $296.3 million outstanding under our credit agreement have repayments due on various dates through July 13, 2022, with the revolving loans outstanding of $249.8 million due on July 13, 2022. Interest payable included in this table is based on the interest rate as of September 30, 2017 and assumes all revolving loan amounts outstanding will not be paid until maturity, but that the term loan amortization payments will be made according to our defined schedule. Interest payable includes the estimated impact of our interest rate swap agreements.
In addition, we have other debt which consists primarily of debt assumed as part of certain of our fiscal 2015 acquisitions, and as of September 30, 2017 we had $8.2 million outstanding for those obligations that have repayments due on various dates through September 2024.
Capital leases. We lease certain machinery and plant equipment under capital lease agreements that expire at various dates through 2022. The aggregate carrying value of the leased equipment under capital leases included in property, plant and equipment, net in our consolidated balance sheet at September 30, 2017, is $39.1 million, net of accumulated depreciation of $29.6 million. The present value of lease installments not yet due included in other current liabilities and other liabilities in our consolidated balance sheet at September 30, 2017 amounts to $37.2 million.
Other Obligations. Other obligations includes the following:
Non-GAAP Financial Measure
Adjusted net operating profit (NOP) and unlevered free cash flow presented below are supplemental measures of our performance that are not required by, or presented in accordance with, GAAP. During the first quarter of fiscal 2018, we removed the cash tax attributable to the current period portion of our consolidated NOP measure as management no longer uses this metric. This metric is the primary metric by which we measure our consolidated financial performance and is intended to supplement investors' understanding of our operating results. Adjusted consolidated NOP is defined as GAAP operating income excluding certain items such as acquisition-related amortization and depreciation, expense recognized for earn-out related charges, including the change in fair value of contingent consideration and compensation expense related to cash-based earn-out mechanisms dependent upon continued employment, share-based compensation related to investment consideration, certain impairment expense and restructuring charges. The interest expense associated with our Waltham lease, as well as realized gains (losses) on currency forward contracts that do not qualify for hedge accounting, are included in adjusted consolidated NOP.
Adjusted NOP is provided to enhance investors' understanding of our current operating results from the underlying and ongoing business for the same reasons it is used by management. For example, as we have become more acquisitive over recent years we believe excluding the costs related to the purchase of a business (such as amortization of acquired intangible assets, contingent consideration, or impairment of goodwill) provides further insight into the performance of the underlying acquired business in addition to that provided by our GAAP operating income. As another example, as we do not apply hedge accounting for our currency forward contracts, we believe inclusion of realized gains and losses on these contracts that are intended to be matched against
