2.We note your reference to various factors impacting your cloud communications revenue for each period presented. Where a material change is attributed to two or more factors, including any offsetting factors, please revise to describe the contribution of each factor in quantified terms. In addition, we note your reference on page 7 to your various market offerings (i.e. Global Communications Plans, Programmable Services and Global Enterprises) as well as your discussion of changes in these offerings in your Q4 2023 earnings call transcript. Please tell us your consideration to include a discussion of the impact of these offerings in your results of operations and revise as necessary. Refer to Item 303(b) of Regulation S-K.
Response:
We respectfully acknowledge the Staff’s comment. Beginning with our Annual Report on Form 10-K for the year ending December 31, 2024, we will more fully quantify our disclosures to explain when a material change is attributed to two or more factors, including any offsetting factors.
Additionally, we respectfully advise the Staff that, as more fully described in our periodic filings, our revenue is primarily earned from the sale of four principal product solutions: Voice, Messaging, Emergency Services and Phone Numbers. We may sell one, two, three or all four of these principal product solutions in widely varying combinations to our customers, whom we collectively aggregate into three broad customer categories – Global Communications Plan, Programmable Services, and Global Enterprises – for descriptive purposes. Beginning with our Form 10-K for the year ending December 31, 2024, we will expand our disclosures to align our disclosures of customer categories with our disclosures and discussion of our four principal product solutions.

4.We note your adjustments to additional paid-in capital and accumulated deficit upon adoption of ASU 2020-06 on January 1, 2022. Please explain to us how you determined the $8,750 thousand adjustment to accumulated deficit. In your response, tell us how the accretion of debt discount recorded in fiscal 2020 and 2021 is reflected in your adjustment to accumulated deficit. Refer to ASC 815-40-65-1(b)(1).
Response:
We respectfully acknowledge the Staff’s comment and explain below how we determined the $8.75 million adjustment to accumulated deficit and how the accretion of debt discount recorded in fiscal 2020 and 2021 was reflected in our adjustment to accumulated deficit.
The Company adopted ASU 2020-06 on January 1, 2022, as more fully described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. Accordingly, our $8.75 million adjustment required by the adoption of ASU 2020-06 consisted of three components: (i) the reversal of the cumulative accretion of the debt discount recorded from 2020 through the end of 2021 of $39.532 million, (ii) an adjustment to debt issuance cost of ($1.757 million) to account for the change in accounting of the conversion option required under ASU 2020-06, and (iii) the tax effect of the adoption of ASU 2020-06 which resulted in an adjustment of ($29.025 million) arising primarily from the removal of the associated deferred tax liability and valuation allowance. The total of these adjustments resulted in the $8.75 million adjustment to accumulated deficit. Per ASC 815-40-65-1(b)(1), these adjustments were made to the opening balance of retained earnings.

Note 5. Leases, page 110
5.Please revise to clarify whether the right of use assets and operating lease liabilities for your new corporate headquarters includes the two ten-year renewal options. Also, describe how you determined the discount rate for the lease. Refer to ASC 842-20-50-3.a.3 and 50-3.c.3.
Response:
We respectfully acknowledge the Staff’s comment. The right of use assets and operating lease liabilities for the Company’s corporate headquarters do not include the two ten-year renewal options, the exclusion of which is reflected in the weighted average remaining lease term of 19.30 years for the Company’s operating leases included in Note 5. Leases.
The Company evaluated the stated yield explicitly set forth in the lease, and determined it was not calculated in a manner as required by ASC 842. Therefore, the Company determined it appropriate to use its incremental borrowing rate (“IBR”) as the discount rate for the lease. The IBR was estimated by determining the risk-free rate for a similar length security and applying a risk premium based on the Company’s estimated credit rating. Because the Company’s estimated credit rating was based on presumed unsecured credit, the rating was increased one level to estimate the yield on secured debt, consistent with ASC 842’s requirements. The estimated rate was 8.78%.
While we have disclosed the weighted average remaining lease term in our periodic filings, for the avoidance of doubt, beginning with our Annual Report on Form 10-K for the year ending December 31, 2024, we will additionally explicitly clarify that the two ten-year renewal options are not included in the operating lease assets and liabilities and the manner in which we determined the discount rate for the lease.
Note 9. Geographic Information, page 119
6.We note your discussion of revenue and long-lived assets in North America. Please tell and revise to disclose what territories comprise North America. To the extent it includes areas besides the United States, revise to separately disclose revenue and long-lived assets attributable to the United States, your country of domicile, and any individually significant foreign country. Refer to ASC 280-10-50-41.
Response:
We respectfully acknowledge the Staff’s comment. Our use of “North America” in Note 9. Geographic Information is equivalent to the United States. We will prospectively revise our labeling convention in future periodic filings for clarity.
