Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivative Instruments and Hedging Activities	Derivative Instruments and Hedging Activities Exchangeable Notes Hedge Transactions On June 25, 2019, concurrently with the pricing of the 4.00% Exchangeable Notes due June 15, 2024 (the "Exchangeable Notes"), and on June 27, 2019, concurrently with the exercise by the initial purchasers involved in the offering of the Exchangeable Notes (the “Initial Purchasers”) of their option to purchase additional Exchangeable Notes, Uniti Fiber Holdings Inc., the issuer of the Exchangeable Notes, entered into exchangeable note hedge transactions with respect to the Company’s common stock (the “Note Hedge Transactions”) with certain of the Initial Purchasers or their respective affiliates (collectively, the “Counterparties”). The Note Hedge Transactions cover, subject to anti-dilution adjustments substantially similar to those applicable to the Exchangeable Notes, the same number of shares of the Company’s common stock that initially underlie the Exchangeable Notes in the aggregate and are exercisable upon exchange of the Exchangeable Notes. The Note Hedge Transactions have an initial strike price that corresponds to the initial exchange price of the Exchangeable Notes, subject to anti-dilution adjustments substantially similar to those applicable to the Exchangeable Notes. The Note Hedge Transactions will expire upon the maturity of the Exchangeable Notes, if not earlier exercised. The Note Hedge Transactions are intended to reduce potential dilution to the Company’s common stock upon any exchange of the Exchangeable Notes and/or offset any cash payments Uniti Fiber Holdings Inc. is required to make in excess of the principal amount of exchanged Exchangeable Notes, as the case may be, in the event that the market value per share of the Company’s common stock, as measured under the Note Hedge Transactions, at the time of exercise is greater than the strike price of the Note Hedge Transactions. The Note Hedge Transactions are separate transactions, entered into by Uniti Fiber Holdings Inc. with the Counterparties, and are not part of the terms of the Exchangeable Notes. Holders of the Exchangeable Notes will not have any rights with respect to the Note Hedge Transactions. The Note Hedge Transactions meet certain accounting criteria under GAAP, are recorded in additional paid-in capital on our Consolidated Balance Sheets and are not accounted for as derivatives that are remeasured each reporting period. Warrant Transactions On June 25, 2019, concurrently with the pricing of the Exchangeable Notes, and on June 27, 2019 concurrently with the exercise by the initial purchasers of their option to purchase additional Exchangeable Notes, the Company entered into warrant transactions to sell to the Counterparties Warrants to acquire, subject to anti-dilution adjustments, up to approximately 27.8 million shares of the Company’s common stock in the aggregate at an exercise price of approximately $16.42 per share. The maximum number of shares of the Company’s common stock that could be issued pursuant to the Warrants is approximately 55.5 million. The Company offered and sold the Warrants in reliance on the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). If the market value per share of the Company’s common stock, as measured under the Warrants, at the time of exercise exceeds the strike price of the Warrants, the Warrants will have a dilutive effect on the Company’s common stock unless, subject to the terms of the Warrants, the Company elects to cash settle the Warrants. The Warrants will expire over a period beginning in September 2024. The Warrants are separate transactions, entered into by the Company with the Counterparties, and are not part of the terms of the Exchangeable Notes. Holders of the Exchangeable Notes will not have any rights with respect to the Warrants. The Warrants meet certain accounting criteria under GAAP, are recorded in additional paid-in capital on our Consolidated Balance Sheets and are not accounted for as derivatives that are remeasured each reporting period. Capped Call Transactions On December 7, 2022, in connection with the pricing of the Convertible 2027 Notes (see Note 1 3), the Company entered into privately negotiated capped call transactions (the “Capped Calls”) with certain financial institutions at a cost of $21.1 million. The Capped Calls cover the same number of shares of the Company’s common stock that initially underlie the Convertible 2027 Notes in the aggregate. By entering into the Capped Calls, the Company expects to reduce the potential dilution to its common stock (or, in the event a conversion of the Convertible 2027 Notes is settled in cash, to reduce its cash payment obligation) in the event that at the time of conversion of the Convertible 2027 Notes its common stock price exceeds the conversion price of the Convertible 2027 Notes. The cap price of the Capped Calls will initially be $10.63 per share of common stock, which represents a premium of 75% over the last reported sale price of the Company’s common stock of $6.075 per share on December 7, 2022 and is subject to customary anti-dilution adjustments substantially similar to those applicable to the Convertible 2027 Notes. The Company used approximately $21.1 million of the net proceeds from the offering of the Convertible 2027 Notes to pay for the cost of the Capped Calls. The Capped Calls meet the criteria for classification in equity, are not remeasured each reporting period and are included as a reduction to additional paid-in-capital within stockholders’ equity. Additionally on December 7, 2022, in connection with the Company’s repurchase of the Exchangeable Notes, the Company entered into partial unwind agreements (the “Unwind Agreements”) with the Counterparties to unwind (see Note 1 3) a portion of the Note Hedge Transactions and the Warrants described above (collectively, the “Unwind Transactions”). In connection with the Unwind Transactions, the Company received cash as a termination payment for of the portion of the Note Hedge Transactions that were unwound, and the Company delivered cash as a termination payment in respect of the portion of the Warrants that were unwound. The amount of cash that was received, which was approximately $1.2 million, and the amount of cash that was delivered to the Counterparties, which was approximately $0.5 million, were based generally on the termination values of the unwound portions of such instruments.
