Paragraphs:
Contractual Obligations
Our contractual obligations as of August 31, 2019 are summarized below. As disclosed below, while we have certain non-cancelable purchase order obligations for property, plant and equipment, we generally do not enter into non-cancelable purchase orders for materials until we receive a corresponding purchase commitment from our customer. Non-cancelable purchase orders do not typically extend beyond the normal lead time of several weeks, at most. Purchase orders beyond this time frame are typically cancelable.
(1) Consists of interest on notes payable and long-term debt outstanding as of August 31, 2019. Certain of our notes payable and long-term debt pay interest at variable rates. We have applied estimated interest rates to determine the value of these expected future interest payments.
(2) Consists of purchase commitments entered into as of August 31, 2019 primarily for property, plant and equipment and software pursuant to legally enforceable and binding agreements.
(3) Includes the estimated company contributions to funded pension plans during fiscal year 2020 and the expected benefit payments for unfunded pension and postretirement plans from fiscal years 2020 through 2029. These future payments are not recorded on the Consolidated Balance Sheets but will be recorded as incurred.
(4) Includes (i) a $28.5 million capital commitment, (ii) a $16.2 million obligation related to a new human resource system and (iii) $33.0 million related to the one-time transition tax as a result of the Tax Act that will be paid in annual installments through fiscal year 2026.
(5) As of August 31, 2019, we have $1.5 million and $103.7 million recorded as a current and a long-term liability, respectively, for uncertain tax positions. We are not able to reasonably estimate the timing of payments, or the amount by which our liability for these uncertain tax positions will increase or decrease over time, and accordingly, this liability has been excluded from the above table.
