Description of the business and summary of significant accounting policies: | 1. Description of the business and summary of significant accounting policies: Reorganization and merger On May 15, 2014, pursuant to the Agreement and Plan of Reorganization (the “Merger Agreement”) by and among Cogent Communications Group, Inc. (“Group”), a Delaware corporation, Cogent Communications Holdings, Inc., a Delaware corporation (“Holdings” or the “Company”) and Cogent Communications Merger Sub, Inc., a Delaware corporation, Group adopted a new holding company organizational structure whereby Group is now a wholly owned subsidiary of Holdings. Holdings is a “successor issuer” to Group pursuant to Rule 12g-3(a) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Cogent Communications, Inc. is wholly owned by Group and the vast majority of Group’s assets, contractual arrangements, and operations are executed by Cogent Communications, Inc. and its subsidiaries. Description of business The Company is a facilities-based provider of low-cost, high-speed Internet access, private network services, and data center colocation space and power. The Company’s network is specifically designed and optimized to transmit packet switched data. The Company delivers its services primarily to small and medium-sized businesses, communications service providers and other bandwidth-intensive organizations in 51 countries across North America, Europe, Asia, South America, Oceania and Africa. The Company is a Delaware corporation and is headquartered in Washington, DC. The Company offers on-net Internet access services exclusively through its own facilities, which run from its network to its customers’ premises. The Company offers its on-net services to customers located in buildings that are physically connected to its network. As a result, the Company is not dependent on local telephone companies or cable TV companies to serve its customers for its on-net Internet access and private network services. The Company’s on- net service consists of high-speed Internet access and private network services offered at speeds ranging from 100 megabits per second to 400 gigabits per second. The Company provides its on-net Internet access and private network services to its corporate and net-centric customers. The Company’s corporate customers are located in multi-tenant office buildings (“MTOBs”) and typically include law firms, financial services firms, advertising and marketing firms, as well as health care providers, educational institutions and other professional services businesses. The Company’s net-centric customers include bandwidth-intensive users that leverage its network to either deliver content to end users or to provide access to residential or commercial internet users. Content delivery customers include over the top (“OTT”) media service providers, content delivery networks, web hosting companies, and commercial content and application software providers. Access customers include access networks comprised of other Internet Service Providers (“ISPs”), telephone companies, mobile phone operators and cable television companies that collectively provide internet access to a substantial number of broadband subscribers and mobile phone subscribers across the world. These net-centric customers generally receive the Company’s services in carrier neutral colocation facilities and in the Company’s own data centers. The Company operates data centers throughout North America and Europe that allow its customers to collocate their equipment and access the Company’s network. In addition to providing on-net services, the Company provides Internet access and private network services to customers that are not located in buildings directly connected to its network. The Company provides these off-net services primarily to corporate customers using other carriers’ circuits to provide the “last mile” portion of the link from the customers’ premises to the Company’s network. The Company also provides certain non-core services that resulted from acquisitions. The Company continues to support but does not actively sell these non-core services. In connection with the Company’s Sprint acquisition (discussed below), the Company will begin to provide optical wavelength services over the Company’s fiber network. The Company will sell these wavelength services to its existing customers, Sprint customers and to new customers who require dedicated optical transport connectivity without the capital and ongoing expenses associated with owning and operating network infrastructure. Acquisition of Sprint Communications On September 6, 2022, Cogent Infrastructure, Inc., a Delaware corporation (the “Buyer”) and a wholly owned subsidiary of the Company, entered into a Membership Interest Purchase Agreement (the “Purchase Agreement”) with Sprint Communications LLC, a Kansas limited liability company (“Sprint Communications”) and an indirect wholly owned subsidiary of T-Mobile US, Inc., a Delaware corporation (“T-Mobile”), and Sprint LLC, a Delaware limited liability company and a direct wholly owned subsidiary of T-Mobile (the “Seller”), pursuant to which the Company will acquire the U.S. long-haul fiber network (including the non-U.S. extensions thereof) of Sprint Communications and its subsidiaries (the “Wireline Business”). The Purchase Agreement provides that, upon the terms and conditions set forth therein, the Company will purchase from the Seller all of the issued and outstanding membership interests (the “Purchased Interests”) of a Delaware limited liability company that holds Sprint Communications’ assets and liabilities relating to the Wireline Business (such transactions contemplated by the Purchase Agreement, collectively, the “Transaction”). The parties have agreed to a $1 purchase price in consideration for the Purchased Interests, subject to customary adjustments set forth in the Purchase Agreement. In addition, at the consummation of the Transaction (the “Closing”), a T-Mobile affiliate will enter into an agreement for IP transit services, pursuant to which T-Mobile will pay the Company an aggregate of $700 million, consisting of (i) $350 million in equal monthly installments during the first year after the Closing and (ii) $350 million in equal monthly installments over the subsequent 42 months. The Purchase Agreement includes customary representations, warranties, indemnities and covenants, including regarding the conduct of the Wireline Business prior to the Closing. In addition, the Closing is subject to customary closing conditions, including as to the receipt of certain required regulatory approvals and consents. Subject to the satisfaction or waiver of certain conditions and the other terms and conditions of the Purchase Agreement, the Transaction is expected to close in 2023. The Purchase Agreement contains certain termination rights for the Buyer and Seller, including that, subject to certain limitations, either the Buyer or the Seller may terminate the Purchase Agreement if the Transaction is not consummated by September 6, 2023, subject to two automatic six-month extensions if certain regulatory approvals have not been obtained. The Purchase Agreement also provides that each party may specifically enforce the other party’s obligations under the Purchase Agreement. The Company has agreed to guarantee the obligations of the Buyer under the Purchase Agreement pursuant to the terms of a Guaranty, dated as of September 6, 2022, by and between the Company and the Seller (the “Parent Guaranty”). The Parent Guaranty contains customary representations, warranties and covenants of the Company and the Seller. Acquisition Related Costs In connection with the Transaction and negotiation of the Purchase Agreement, the Company incurred $2.2 million of professional fees in the year ended December 31, 2022. Principles of consolidation The consolidated financial statements have been prepared in accordance with United States generally accepted accounting principles and include the accounts of the Company and all of its wholly-owned and majority-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation. Use of estimates The preparation of consolidated financial statements in conformity with United States generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates. Allowance for credit losses The Company establishes an allowance for credit losses and other sales credit adjustments related to its trade receivables. Trade receivables are recorded at the invoiced amount and can bear interest. Allowances for sales credits are established through a reduction of revenue, while allowances for credit losses are established through a charge to selling, general, and administrative expenses as bad debt expense. The Company assesses the adequacy of these reserves by evaluating factors, such as the length of time individual receivables are past due, historical collection experience, and changes in the credit worthiness of its customers. The Company also assesses the ability of specific customers to meet their financial obligations and establishes specific allowances related to these customers. If circumstances relating to specific customers change or economic conditions change such that the Company’s past collection experience and assessment of the economic environment are no longer appropriate, the Company’s estimate of the recoverability of its trade receivables could be impacted. Accounts receivable balances are written off against the allowance for credit losses after all means of internal collection activities have been exhausted and the potential for recovery is considered remote. The Company uses third-party collection services to continue to seek collection for it’s written off accounts receivable. Effective January 1, 2020, the Company adopted Accounting Standards Update (“ASU”) No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments Current-period Balance at Provision for Write offs Balance at Beginning Expected Credit Charged Against End of Description of Period Losses Allowance Period Allowance for credit losses (deducted from accounts receivable) Year ending December 31, 2022 $ 1,510 $ 4,318 $ (3,525) $ 2,303 Year ending December 31, 2021 $ 1,921 $ 5,595 $ (6,006) $ 1,510 Year ending December 31, 2020 $ 1,771 $ 4,997 $ (4,847) $ 1,921 The current-period provision for expected credit losses is net of bad debt recoveries of $1.9 million, $2.2 million and $1.2 million for the years ended December 31, 2022, 2021 and 2020, respectively. Leases In February 2016, the FASB issued ASU No. 2016-02, Leases not reassessing whether any existing contracts contained leases, not reconsidering lease classification, not reassessing initial direct costs and using hindsight in determining the lease reasonably certain term of its leases. Year Year Ended Ended December 31, 2022 December 31, 2021 Finance lease cost amortization of right-of-use assets $ 28,915 $ 26,424 Interest expense on finance lease liabilities 23,317 19,419 Operating lease cost 18,331 18,382 Total lease costs 70,563 64,225 Other lease information Cash paid for amounts included in the measurement of lease liabilities Operating cash flows from finance leases (23,317) (17,366) Operating cash flows from operating leases (18,836) (20,194) Financing cash flows from finance leases (45,472) (23,054) Right-of-use assets obtained in exchange for new finance lease liabilities 107,875 50,831 Right-of-use assets obtained in exchange for new operating lease liabilities 11,168 17,853 Weighted-average remaining lease term — finance leases (in years) 13.5 12.6 Weighted-average remaining lease term — operating leases (in years) 16.6 18.7 Weighted average discount rate — finance leases 8.6 % 9.0 % Weighted average discount rate — operating leases 5.4 % 5.4 % Finance leases—fiber lease agreements The Company has entered into lease agreements with numerous providers of dark fiber under indefeasible-right-of-use agreements (“IRUs”). These IRUs typically have initial terms of 15-20 years and include renewal options after the initial lease term. The Company establishes the number of renewal option periods used in determining the lease term based upon its assessment at the inception of the lease of the number of option periods for which failure to renew the lease imposes a penalty in such amount that renewal appears to be reasonably certain. The option to renew may be automatic, at the option of the Company or mutually agreed to between the dark fiber provider and the Company. Once the Company has accepted the related fiber route, leases that meet the criteria for treatment as finance leases are recorded as a finance lease obligation and an IRU asset. The interest rate used in determining the present value of the aggregate future minimum lease payments is the Company’s incremental borrowing rate for the reasonably certain lease term. The determination of the Company’s incremental borrowing rate requires some judgment. Finance lease assets are included in property and equipment in the Company’s consolidated balance sheets. As of December 31, 2022, the Company had committed to additional dark fiber IRU lease agreements totaling $70.3 million in future payments to be paid over periods of up to 20 years. These obligations begin when the related fiber is accepted, which is generally expected to occur in the next 12 months. Operating leases The Company leases office space and certain data center facilities under operating leases. In certain cases the Company also enters into short-term operating leases for dark fiber. Right-of-use assets represent the Company’s right to use an underlying asset for the lease term and lease liabilities represent its obligation to make lease payments under the lease. Operating lease right-of-use assets and liabilities are recognized at the lease commencement date based on the present value of lease payments over the reasonably certain lease term. The implicit rates within the Company’s operating leases are generally not determinable and the Company uses its incremental borrowing rate at the lease commencement date to determine the present value of its lease payments. The determination of the Company’s incremental borrowing rate requires some judgment. The Company determines its incremental borrowing rate for each lease using its current borrowing rate, adjusted for various factors including level of collateralization and term to align with the term of the lease. Certain of the Company’s leases include options to extend or terminate the lease. The Company establishes the number of renewal option periods used in determining the operating lease term based upon its assessment at the inception of the operating lease of the number of option periods for which failure to renew the lease imposes a penalty in such amount that renewal appears to be reasonably certain. The option to renew may be automatic, at the option of the Company or mutually agreed to between the landlord or dark fiber provider and the Company. Once the Company has accepted the related fiber route or the facility lease term has begun, the present value of the aggregate future minimum operating lease payments is recorded as an operating lease liability and a right-of-use leased asset. Lease incentives and deferred rent liabilities for facilities operating leases are presented with, and netted against, the right-of-use leased asset. Lease expense for lease payments is recognized on a straight-line basis over the term of the lease. The future minimum payments under these operating lease and finance lease agreements are as follows (in thousands): Operating Finance For the twelve months ending December 31, Leases Leases 2023 $ 17,181 $ 40,425 2024 16,658 42,686 2025 14,255 37,458 2026 12,285 34,685 2027 10,900 35,521 Thereafter 87,702 333,836 Total minimum lease obligations 158,981 524,611 Less—amounts representing interest (52,389) (220,385) Present value of minimum lease obligations 106,592 304,226 Current maturities (12,005) (17,182) Lease obligations, net of current maturities $ 94,587 $ 287,044 Revenue recognition The Company recognizes revenue under ASU No. 2014-09, Revenue from Contracts with Customers The Company’s service offerings consist of on-net and off-net telecommunications services. Fixed fees are billed monthly in advance and usage fees are billed monthly in arrears. Amounts billed are due upon receipt and contract lengths range from month to month to 60 months. The Company satisfies its performance obligations to provide services to customers over time as the services are rendered. In accordance with ASC 606, revenue is recognized when a customer obtains the promised service. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these services. The Company has adopted the practical expedient related to certain performance obligation disclosures since it has a right to consideration from its customer in an amount that corresponds directly with the value to the customer of the Company’s performance completed to date. To achieve this core principle, the Company follows the following five steps: 1) Identification of the contract, or contracts with a customer; 2) Identification of the performance obligations in the contract; 3) Determination of the transaction price; 4) Allocation of the transaction price to the performance obligations in the contract; and 5) Recognition of revenue when, or as, the Company satisfies a performance obligation. Fees billed in connection with customer installations are deferred (as deferred revenue) and recognized as noted above. To the extent a customer contract is terminated prior to its contractual end the customer is subject to termination fees. The Company vigorously seeks payment of termination fees. The Company recognizes revenue for termination fees as they are collected. Service revenue recognized from amounts in deferred revenue (contract liabilities) at the beginning of the period during the years ended December 31, 2022, 2021 and 2020 was $5.0 million, $4.6 million and $4.4 million, respectively. Amortization expense for contract costs for the years ended December 31, 2022, 2021 and 2020 was $19.4 million, $18.4 million and $17.1 million, respectively. Gross receipts taxes, universal service fund and other surcharges Revenue recognition standards include guidance relating to taxes or surcharges assessed by a governmental authority that are directly imposed on a revenue-producing transaction between a seller and a customer and may include, but are not limited to, gross receipts taxes, excise taxes, Universal Service Fund fees and certain state regulatory fees. Such charges may be presented gross or net based upon the Company’s accounting policy election. The Company records certain excise taxes and surcharges on a gross basis and includes them in its revenues and costs of network operations. Excise taxes and surcharges billed to customers and recorded on a gross basis (as service revenue and network operations expense) were $15.4 million, $18.5 million, and $15.1 million for the years ended December 31, 2022, 2021 and 2020, respectively. Network operations Network operations expenses include the costs of personnel and related operating expenses associated with service delivery, network management, and customer support, network facilities costs, fiber and equipment maintenance fees, leased circuit costs, access fees paid to building owners and certain excise taxes and surcharges recorded on a gross basis. The Company estimates its accruals for any disputed leased circuit obligations based upon the nature and age of the dispute. Network operations costs are impacted by the timing and amounts of disputed circuit costs. The Company generally records these disputed amounts when billed by the vendor and reverses these amounts when the vendor credit has been received or the dispute has otherwise been resolved. The Company does not allocate depreciation and amortization expense to its network operations expense. Foreign currency translation adjustment and comprehensive income The consolidated financial statements of the Company’s non-US operations are translated into US dollars using the period-end foreign currency exchange rates for assets and liabilities and the average foreign currency exchange rates for revenues and expenses. Gains and losses on translation of the accounts are accumulated and reported as a component of other comprehensive income in stockholders’ equity. The Company’s only components of “other comprehensive income” are currency translation adjustments for all periods presented. The Company considers the majority of its investments in its foreign subsidiaries to be long-term in nature. The Company’s foreign exchange transaction gains (losses) are included within interest income and other on the consolidated statements of comprehensive income. Financial instruments The Company considers all highly liquid investments with an original maturity of three months or less at purchase to be cash equivalents. The Company determines the appropriate classification of its investments at the time of purchase and evaluates such designation at each balance sheet date. At December 31, 2022 and December 31, 2021, the carrying amount of cash and cash equivalents, restricted cash, accounts receivable, prepaid and other current assets, accounts payable, and accrued expenses approximated fair value because of the short-term nature of these instruments. The Company measures its cash equivalents and restricted cash at amortized cost, which approximates fair value based upon quoted market prices (Level 1). Based upon recent trading prices (Level 2—market approach), at December 31, 2022, the fair value of the Company’s $500.0 million senior secured notes due 2026 was $452.5 million, the fair value of the Company’s $450.0 million senior unsecured notes due 2027 was $441.0 million and the estimated fair value of the Company’s Swap Agreement was $52.1 million. Restricted cash and interest rate swap agreement Restricted cash represents amounts held in segregated bank accounts by our clearing broker as margin in support of our Swap Agreement, as discussed in Note 4, and was $52.1 million as of December 31, 2022. Additional cash may be further restricted to maintain our interest rate swap instrument as interest rates fluctuate and margin requirements change. The Company does not use derivative financial instruments for trading purposes. Concentrations of credit risk The Company’s assets that are exposed to credit risk consist of its cash and cash equivalents, other assets and accounts receivable. As of December 31, 2022 and 2021, the Company’s cash equivalents were invested in demand deposit accounts, overnight investments and money market funds. The Company places its cash equivalents in instruments that meet high-quality credit standards as specified in the Company’s investment policy guidelines. Accounts receivable are due from customers located in major metropolitan areas in the United States, Europe, Canada, Mexico, Asia, South America, Oceania and Africa. Receivables from the Company’s net-centric (wholesale) customers are generally subject to a higher degree of credit risk than the Company’s corporate customers. The Company relies upon an equipment vendor for the majority of its network equipment and is also dependent upon many third-party fiber providers for providing its services to its customers. Property and equipment Property and equipment are recorded at cost and depreciated once deployed using the straight-line method over the estimated useful lives of the assets. Useful lives are determined based on historical usage with consideration given to technological changes and trends in the industry that could impact the asset utilization. System infrastructure costs include the capitalized compensation costs of employees directly involved with construction activities and costs incurred by third-party contractors. Assets and liabilities under finance leases are recorded at the lesser of the present value of the aggregate future minimum lease payments or the fair value of the assets under lease. Leasehold improvements include costs associated with building improvements and customer installation costs. The Company determines the number of renewal option periods, if any, included in the lease term for purposes of amortizing leasehold improvements and the lease term of its finance leases based upon its assessment at the inception of the lease for which the failure to renew the lease imposes a penalty on the Company in such amount that a renewal appears to be reasonably assured. Expenditures for maintenance and repairs are expensed as incurred. Depreciation and amortization periods are as follows: Type of asset Depreciation or amortization period Indefeasible rights of use (IRUs) Shorter of useful life or the IRU lease agreement; generally 15 to 20 years Network equipment 3 to 8 years Leasehold improvements Shorter of lease term, including reasonably assured renewal periods, or useful life Software 5 years Owned buildings 40 years Office and other equipment 3 to 7 years System infrastructure 5 to 10 years Long-lived assets The Company’s long-lived assets include property and equipment. These long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Impairment is determined by comparing the carrying value of these long-lived assets to management’s probability weighted estimate of the future undiscounted cash flows expected to result from the use of the assets. In the event an impairment exists, a loss is recognized based on the amount by which the carrying value exceeds the fair value of the asset, which would be determined by using quoted market prices or valuation techniques such as the discounted present value of expected future cash flows, appraisals, or other pricing models. In the event there are changes in the planned use of the Company’s long-term assets or the Company’s expected future undiscounted cash flows are reduced significantly, the Company’s assessment of its ability to recover the carrying value of these assets could change. Equity-based compensation The Company recognizes compensation expense for its share-based payments granted to its employees based on their grant date fair values with the expense being recognized on a straight-line basis over the requisite service period. The Company begins recording equity-based compensation expense related to performance awards when it is considered probable that the performance conditions will be met and for market-based awards compensation cost is recognized if the service condition is satisfied even if the market condition is not satisfied. Equity-based compensation expense is recognized in the statements of comprehensive income in a manner consistent with the classification of the employee’s salary and other compensation. Income taxes The Company’s deferred tax assets or liabilities are computed based upon the differences between financial statement and income tax bases of assets and liabilities using the enacted marginal tax rate. Deferred income tax expenses or benefits are based upon the changes in the assets or liability from period to period. At each balance sheet date, the Company assesses the likelihood that it will be able to realize its deferred tax assets. Valuation allowances are established when management determines that it is “more likely than not” that some portion or all of the deferred tax asset may not be realized. The Company considers all available positive and negative evidence in assessing the need for a valuation allowance including its historical operating results, ongoing tax planning, and forecasts of future taxable income, on a jurisdiction by jurisdiction basis. The Company reduces its valuation allowance if the Company concludes that it is “more likely than not” that it would be able to realize its deferred tax assets. Management determines whether a tax position is more likely than not to be sustained upon examination based on the technical merits of the position. Once it is determined that a position meets this recognition threshold, the position is measured to determine the amount of benefit to be recognized in the financial statements. The Company adjusts its estimated liabilities for uncertain tax positions periodically because of ongoing examinations by, and settlements with, the various taxing authorities, as well as changes in tax laws, regulations and interpretations. The Company’s policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of its income tax expense. Basic and diluted net income per common share Basic earnings per share (“EPS”) excludes dilution for common stock equivalents and is computed by dividing net income or (loss) available to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS is based on the weighted-average number of shares of common stock outstanding during each period, adjusted for the effect of dilutive common stock equivalents. Shares of restricted stock are included in the computation of basic EPS as they vest and are included in diluted EPS, to the extent they are dilutive, determined using the treasury stock method. The following details the determination of the diluted weighted average shares: Year Ended Year Ended Year Ended December 31, December 31, December 31, 2022 2021 2020 Weighted average common shares—basic 46,875,992 46,419,180 45,947,772 Dilutive effect of stock options 16,064 34,007 80,849 Dilutive effect of restricted stock 315,242 510,733 639,577 Weighted average common shares—diluted 47,207,298 46,963,920 46,668,198 The following details unvested shares of restricted common stock as well as the anti-dilutive effects of stock options and restricted stock awards outstanding: December 31, December 31, December 31, 2022 2021 2020 Unvested shares of restricted common stock 1,164,021 1,253,321 1,339,596 Anti-dilutive options for common stock 105,556 45,809 32,324 Anti-dilutive shares of restricted common stock 541,608 86,619 223,118 |
