Paragraphs:
OBLIGATIONS AND COMMITMENTS
As part of our ongoing operations, we enter into arrangements that obligate us to make future payments under contracts such as lease agreements, debt agreements, and unconditional purchase obligations (i.e., obligations to transfer funds in the future for fixed or minimum quantities of goods or services at fixed or minimum prices, such as "take-or-pay" contracts). The unconditional purchase obligation arrangements are entered into in our normal course of business in order to ensure adequate levels of sourced product are available. Of these items, debt, notes payable, and capital lease obligations, which totaled $10.72 billion as of May 26, 2019, were recognized as liabilities in our Consolidated Balance Sheets. Operating lease obligations and unconditional purchase obligations, which totaled $1.75 billion as of May 26, 2019, were not recognized as liabilities in our Consolidated Balance Sheets, in accordance with U.S. GAAP.
A summary of our contractual obligations as of May 26, 2019, was as follows:
Amount includes open purchase orders and agreements, some of which are not legally binding and/or may be cancellable. Such agreements are generally settleable in the ordinary course of business in less than one year.
We are also contractually obligated to pay interest on our long-term debt and capital lease obligations. The weightedaverage coupon interest rate of the long-term debt obligations outstanding as of May 26, 2019, was approximately 4.7%.
As of May 26, 2019, we had aggregate unfunded pension and postretirement benefit obligations totaling $131.7 million and $87.8 million, respectively. These amounts are not included in the table above as the unfunded obligations are remeasured each fiscal year, thereby resulting in our inability to accurately predict the ultimate amount and timing of any future required contributions to such plans. Based on current statutory requirements, we are not obligated to fund any amount to our qualified pension plans during the next twelve months. We estimate that we will make payments of approximately $14.2 million and $10.8 million over the next twelve months to fund our pension and postretirement plans, respectively. See Note 19 "Pension and Postretirement Benefits" to the consolidated financial statements and "Critical Accounting Estimates - Employment Related Benefits" contained in this report for further discussion of our pension obligations and factors that could affect estimates of this liability.
As part of our ongoing operations, we also enter into arrangements that obligate us to make future cash payments only upon the occurrence of a future event (e.g., guarantees of debt or lease payments of a third party should the third party be unable to perform). In accordance with U.S. GAAP, such commercial commitments are not recognized as liabilities in our Consolidated Balance Sheets. As of May 26, 2019, we had other commercial commitments totaling $5.3 million, of which $3.7 million expire in less than one year and $1.6 million expire in one to three years.
In addition to the other commercial commitments, as of May 26, 2019, we had $56.4 million of standby letters of credit issued on our behalf. These standby letters of credit are primarily related to our self-insured workers compensation programs and are not reflected in our Consolidated Balance Sheets.
In certain limited situations, we will guarantee an obligation of an unconsolidated entity. We guarantee certain leases resulting from the divestiture of the JM Swank business completed in the first quarter of fiscal 2017. As of May 26, 2019, the remaining terms of these arrangements did not exceed four years and the maximum amount of future payments we have guaranteed was $1.2 million. In addition, we guarantee a lease resulting from an exited facility. As of May 26, 2019, the remaining term of this arrangement did not exceed eight years and the maximum amount of future payments we have guaranteed was $19.1 million.
We also guarantee an obligation of the Lamb Weston business pursuant to a guarantee arrangement that existed prior to the Spinoff and remained in place following completion of the Spinoff until such guarantee obligation is substituted for guarantees issued by Lamb Weston. Pursuant to the separation and distribution agreement, dated as of November 8, 2016 (the "Separation Agreement"), between us and Lamb Weston, this guarantee arrangement is deemed a liability of Lamb Weston that was transferred to Lamb Weston as part of the Spinoff. Accordingly, in the event that we are required to make any payments as a result of this guarantee arrangement, Lamb Weston is obligated to indemnify us for any such liability, reduced by any insurance proceeds received by us, in accordance with the terms of the indemnification provisions under the Separation Agreement.
Lamb Weston is a party to an agricultural sublease agreement with a third party for certain farmland through 2020 (subject, at Lamb Weston's option, to extension for two additional five-year periods). Under the terms of the sublease agreement, Lamb 39 Weston is required to make certain rental payments to the sublessor. We have guaranteed Lamb Weston's performance and the payment of all amounts (including indemnification obligations) owed by Lamb Weston under the sublease agreement, up to a maximum of $75.0 million. We believe the farmland associated with this sublease agreement is readily marketable for lease to other area farming operators. As such, we believe that any financial exposure to the company, in the event that we were required to perform under the guaranty, would be largely mitigated.
The obligations and commitments tables above do not include any reserves for uncertainties in income taxes, as we are unable to reasonably estimate the ultimate amount or timing of settlement of our reserves for income taxes. The liability for gross unrecognized tax benefits at May 26, 2019 was $44.1 million. The net amount of unrecognized tax benefits at May 26, 2019, that, if recognized, would favorably impact our effective tax rate was $37.3 million. Recognition of these tax benefits would have a favorable impact on our effective tax rate.
Question:
What is the ratio (in percentage) of total notes payable to total capital lease obligations?
Answer: 1.0/165.4  = 0.6
