Investments, Debt and Equity Securities [Abstract]
Investments	Investments Investments consist of equity and debt securities. Investment in equity securities On October 7, 2021, we completed the separation of our cloud fax business (the “Separation”) into an independent publicly traded company. Following the Separation, the Company retained shares of publicly traded common stock of Consensus Cloud Solutions, Inc. (“Consensus”). During the three and nine months ended September 30, 2023, the Company sold zero and 52,393 shares, respectively, of common stock of Consensus in the open market. As of December 31, 2023, the Company held approximately 1.0 million shares of the common stock of Consensus with the carrying value of $27.1 million, which was included in ‘Short-term investments’ in the Condensed Consolidated Balance Sheets. The Company accounted for its investment in Consensus at fair value under the fair value option, and the related fair value gains and losses were recognized in earnings. During the second quarter of 2024, the Company sold its remaining 1,034,295 shares of Consensus common stock in the open market. For the three months ended September 30, 2024 and 2023, losses of zero and $6.0 million, respectively, were recorded in the Condensed Consolidated Statement of Operations. For the nine months ended September 30, 2024 and 2023, losses of $7.7 million and $29.2 million, respectively, were recorded in the Condensed Consolidated Statement of Operations. On July 31, 2023, the Company entered into an agreement to purchase $25.0 million of equity in Xyla, Inc. (“Xyla”) for a minority ownership stake. This minority investment was made in the form of cash and shares of the Company’s common stock. The Company accounts for its investment in Xyla as an equity investment without a readily determinable fair value measured under the measurement alternative in accordance with ASC Topic 321, Investments — Equity Securities. As of each September 30, 2024 and December 31, 2023, the carrying value of the investment in Xyla was $25.3 million, including transaction costs, and is included in ‘Long-term investments’ in the Condensed Consolidated Balance Sheets. Investment in corporate debt security On April 12, 2022, the Company entered into an agreement with an entity to acquire 4% convertible notes with an aggregate value of $15.0 million. On May 19, 2023, the Company entered into the Note Amendment Agreement (the “Amendment”) with respect to the same entity. The Amendment increased the interest rate on the convertible notes to 6%, extended the maturity date, and subordinated all existing and future obligations, liabilities, and indebtedness of the entity to the entity’s senior creditor, as defined in the Amendment. This investment is included in ‘Long-term investments’ in the Condensed Consolidated Balance Sheets and is classified as available-for-sale. The investment was initially measured at its transaction price and subsequently remeasured at fair value, with unrealized gains and losses reported as a component of other comprehensive income. As of September 30, 2024, both the carrying value and the maximum exposure of the Company’s investment in corporate debt securities was approximately $16.5 million, with a contractual maturity date that was more than one year but less than five years. As of December 31, 2023, both the carrying value and the maximum exposure of the Company’s investment in corporate debt securities was approximately $15.7 million, with a contractual maturity date that was more than one year but less than five years. Cumulative gross unrealized gains on investment in corporate debt securities as of September 30, 2024 and December 31, 2023 were approximately $1.5 million and $0.7 million, respectively. There were no investments in an unrealized loss position as of September 30, 2024 and December 31, 2023. During the three and nine months ended September 30, 2024 and 2023, the Company did not recognize any other-than-temporary impairment losses on its debt securities. Equity method investment On September 25, 2017, the Company entered into a commitment to invest in OCV Fund I, LP (the “OCV Fund”). The Company recognizes its equity in the net earnings or losses relating to the investment in the OCV Fund on a one-quarter lag due to the timing and availability of financial information from the OCV Fund. If the Company becomes aware of a significant decline in value that is other-than-temporary, the loss will be recorded in the period in which the Company identifies the decline. During the three months ended September 30, 2024 and 2023, the Company recognized (loss) income from the equity method investment of $(0.1) million and $0.1 million, net of tax benefit (expense), respectively. During the nine months ended September 30, 2024 and 2023, the Company recognized income (loss) from the equity method investment of $8.1 million and $(9.7) million, net of tax (expense) benefit, respectively. The income (loss) in the periods presented were primarily the result of gains or losses in the underlying investments. As of September 30, 2024, both the carrying value and the maximum exposure of the Company’s equity method investment was approximately $110.9 million. As of December 31, 2023, both the carrying value and the maximum exposure of the Company’s equity method investment was approximately $99.9 million. These equity securities are included in ‘Long-term investments’ in the Condensed Consolidated Balance Sheets. As a limited partner, the Company’s maximum exposure to loss is limited to its proportional ownership in the partnership. In addition, the Company is not required to contribute any future capital. Finally, there are no call or put options, or other types of arrangements, which limit the Company’s ability to participate in losses and returns of the OCV Fund.
