4.00% Convertible Senior Notes

On May 28, 2019, the Company issued, in a registered public offering in the U.S., Convertible Senior Notes (the “Notes”) with an aggregate principal amount of $207 million. The Notes bear interest at a rate of 4.00% per year payable semi-annually in arrears on June 1 and December 1 of each year, beginning December 1, 2019. The Notes will mature on June 1, 2024, unless repurchased, redeemed or converted in accordance with their terms prior to such date.

The net proceeds from the offering of the Notes were approximately $200 million, after deducting issuance costs of $7 million. The Company accounted for these issuance costs as a direct deduction from the carrying amount of the Notes. These costs are being amortized into interest expense for 5 years or through June 2024.

The conversion rate is 44.8179 shares of common stock per $1,000 principal amount of the Notes (equivalent to an initial conversion price of approximately $22.3125 per share of common stock). The conversion rate will be subject to adjustment in some events but will not be adjusted for any accrued and unpaid interest. In addition, following certain corporate events that occur prior to the maturity date or if the Company deliver a notice of redemption, the Company will, in certain circumstances, increase the conversion rate for a holder who elects to convert its Notes in connection with such a corporate event or notice of redemption, as the case may be. In no event will the conversion rate per $1,000 principal amount of the Notes as a result of this adjustment exceed 57.1428 shares of common stock, as stipulated in the indenture.

The Company may not redeem the Notes prior to June 1, 2022. On or after this date, the Company may redeem for cash, shares or both all or any portion of the Notes, at our option, if the last reported sale price of the Company's common stock has been at least 130% of the conversion price then in effect for at least 20 trading days (whether or not consecutive) during any 30 consecutive trading day period (including the last trading day of such period) ending on, and including, the trading day immediately preceding the date on which we provide notice of redemption at a redemption price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest to, but excluding, the redemption date. No sinking fund is provided for the Notes.

If the Company undergoes a fundamental change (as defined in the indenture), holders may require the Company to repurchase for cash all or any portion of their Notes at a fundamental change repurchase price equal to 100% of the principal amount of the Notes to be repurchased, plus accrued and unpaid interest to, but excluding, the fundamental change repurchase date.

The Notes are the Company's general unsecured obligations and are rank senior in right of payment to all of the Company's indebtedness that is expressly subordinated in right of payment to the Notes, equal in right of payment with all of the Company's liabilities that are not so subordinated, effectively junior to any of the Company's secured indebtedness to the extent of the value of the assets securing such indebtedness, and structurally junior to all indebtedness and other liabilities (including trade payables) of our subsidiaries.

Holders may convert their Notes at their option at any time prior to the close of business on the business day immediately preceding March 1, 2024 only under the following circumstances: (1) if the last reported sale price of the Company's common stock for at least 20 trading days, whether or not consecutive, during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding fiscal quarter is greater than or equal to 130% of the conversion price on each applicable trading day; (2) during the five business day period after any ten consecutive trading day period (the “measurement period”) in which the "trading price" (as defined in the indenture) per $1,000 principal amount of Notes for each trading day of the measurement period was less than 98% of the product of the last reported sale price of our common stock and the conversion rate on each such trading day; (3) if the Company calls any or all of the Notes for redemption, at any time prior to the close of business on the scheduled trading day immediately preceding the redemption date; or (4) upon the occurrence of specified corporate events.

On or after March 1, 2024 until the close of business on the second scheduled trading day immediately preceding the maturity date, holders may convert all or any portion of their Notes at any time, regardless of the foregoing circumstances. Upon conversion, the Company will pay or deliver, as the case may be, cash, shares of our common stock or a combination of cash and shares of our common stock, at the Company's election, as stipulated in the indenture.

In accounting for the issuance of the Notes, the Company separated the Notes into liability and equity components. The carrying amount of the liability component was calculated by measuring the fair value of a similar liability that does not have an associated convertible feature. The carrying amount of the equity component, representing the conversion option, which does not meet the criteria for separate accounting as a derivative as it is indexed to the Company's own stock, was determined by deducting the fair value of the liability component from the par value of the Notes. The difference between the principal amount of the Notes and the liability component represents the debt discount, which is recorded as a direct deduction from the related debt liability in the Consolidated and Balance Sheet and amortized to interest expense using the effective interest method over the term of the Notes. The effective interest rate on the Notes is 10%. The equity component of the Notes of approximately $46 million is included in additional paid-in capital in the Consolidated Balance Sheet and is not remeasured as long as it continues to meet the conditions for equity classification. The Company allocated transaction costs related to the Notes using the same proportions as the proceeds from the Notes. Transaction costs attributable to the liability component were recorded as a direct deduction from the related debt liability in the Consolidated Balance Sheet and amortized to interest expense over the term of the Notes, and transaction costs attributable to the equity component were netted with the equity component in shareholders’ equity.

The following table presents the outstanding principal amount and carrying value of the Notes:

4.00% Convertible Senior Notes due 2024	As of December 31
(Dollars in millions)	2021		2020
Principal amount (face value)	$	207	$	207
Unamortized issuance cost	(3)		(4)
Unamortized debt discount	(25)		(33)
Net Carrying value	$	179	$	170

The Company recognized total interest expense related to the Notes of approximately $18 million and $17 million for the year ended December 31, 2021 and 2020, respectively.

The estimated fair value of the Notes was $341 million and $255 million as of December 31, 2021 and 2020, respectively. The estimated fair value of the Notes was determined through consideration of quoted market prices. The fair value is classified as Level 2, as defined in Note 9, Fair Value Measurements.
