Accounts Receivable Sales Agreement
On September 13, 2019, we entered into the $250 million A/R Agreement whereby the Originators sold or contributed, and will on an ongoing basis continue to sell or contribute, certain of their domestic trade accounts receivables to a wholly-owned, bankruptcy-remote, SPE. The SPE would in turn, sell, transfer, convey and assign to third-party Purchasers, all the rights, title and interest in and to its pool of eligible receivables. This agreement is currently scheduled to expire on August 13, 2021.
The amount available for purchase under the A/R Agreement fluctuates over time based on the total amount of eligible receivables generated during the normal course of business after excluding excess concentrations and certain other ineligible receivables. The maximum purchase commitment of the Purchasers under the A/R Agreement is approximately $250.0 million and the amount of receivables purchased by the Purchasers as of March 31, 2021 was $74.0 million.
The Originators, Nabors Delaware, the SPE, and the Company provide representations, warranties, covenants and indemnities under the A/R Agreement and the Indemnification Guarantee. See further details at Note 5—Accounts Receivable Sales Agreement.
Future Cash Requirements
Our current cash and investments, projected cash flows from operations, proceeds from equity or debt issuances and our revolving credit facility are expected to adequately finance our purchase commitments, capital expenditures, acquisitions, scheduled debt service requirements, and all other expected cash requirements for at least the next 12 months. However, we can make no assurances that our current operational and financial projections will prove to be correct, especially in light of the effects the COVID-19 pandemic has on oil and natural gas prices and, in turn, our business. A sustained period of highly depressed oil and natural gas prices could have a significant effect on our customers’ capital expenditure spending and therefore our operations, cash flows and liquidity.
Purchase commitments outstanding at March 31, 2021 totaled approximately $132.3 million, primarily for capital expenditures, other operating expenses and purchases of inventory. We can reduce planned expenditures if necessary or increase them if market conditions and new business opportunities warrant it. The level of our outstanding purchase commitments and our expected level of capital expenditures over the next 12 months represent a number of capital programs that are currently underway or planned.
See our discussion of guarantees issued by Nabors that could have a potential impact on our financial position, results of operations or cash flows in future periods included below under “Off-Balance Sheet Arrangements (Including Guarantees).”
There have been no material changes to the contractual cash obligations table that was included in our 2020 Annual Report.
On August 25, 2015, our Board authorized a share repurchase program (the “program”) under which we may repurchase, from time to time, up to $400.0 million of our common shares by various means, including in the open market or in privately negotiated transactions. Authorization for the program, which was renewed in February 2019, does not have an expiration date and does not obligate us to repurchase any of our common shares. Since establishing the
