Summary of Significant Accounting Policies

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Preparation of Consolidated Financial Statements

The consolidated financial statements include the accounts of us and our subsidiaries. All significant intercompany transactions and balances have been eliminated. Comprehensive income is equal to net income for all periods presented. The preparation of the consolidated financial statements in conformity with generally accepted accounting principles in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. The accounting estimates that require management’s most difficult and subjective judgments include: assessment and valuation of intangibles, accounts receivable allowance, useful lives of property, plant and equipment and capitalized labor. Actual results could differ from those and other estimates.

Reclassifications

Certain reclassifications have been made to prior year amounts to conform to the current year presentation.

Revenue Recognition

Video, high speed data (“HSD”), phone and business services revenues are recognized when the services are provided to our customers. We generally bill customers in advance for the services and equipment they have chosen to use and record such amounts as deferred revenue until the services are provided and the equipment is used. Credit risk is managed by disconnecting services to customers who are deemed to be delinquent. Installation revenues are recognized as customer connections are completed because installation revenues are less than direct installation costs. Advertising sales are recognized in the period that the advertisements are exhibited. Deposits and up-front fees collected from customers are recognized as deferred revenue until the earnings process is complete. Under the terms of our franchise agreements, we are required to pay local franchising authorities up to 5% of our gross revenues derived from providing video service. We normally pass these fees through to our customers. Because franchise fees are our obligation, we present them on a gross basis with a corresponding expense. Franchise fees reported on a gross basis amounted to approximately $22.7 million, $22.1 million, and $21.7 million for the years ended December 31, 2016, 2015 and 2014, respectively. Franchise fees are reported in video revenue and included in selling, general and administrative expenses.

Allowance for Doubtful Accounts

The allowance for doubtful accounts represents our best estimate of probable losses in the accounts receivable balance. The allowance is based on the number of days outstanding, customer balances, recoveries, historical experience and other currently available information.

Concentration of Credit Risk

Our accounts receivable are comprised of amounts due from customers in varying regions throughout the United States. Concentration of credit risk with respect to these receivables is limited due to the large number of customers comprising our customer base and their geographic dispersion. We invest our cash with high quality financial institutions.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Additions to property, plant and equipment generally include material, labor and indirect costs. Depreciation is calculated on a straight-line basis over the following useful lives:


Buildings		40 years
Leasehold improvements		Lesser of: life of respective lease or life of asset
Cable systems, equipment and customer devices		5-20 years
Vehicles		4-5 years
Furniture, fixtures, and office equipment		5 years

We capitalize improvements that extend asset lives and expense repairs and maintenance as incurred. At the time of retirements, write-offs, sales or other dispositions of property, the original cost and related accumulated depreciation are removed from the respective accounts and any resulting gains or losses are included in depreciation and amortization expense in the consolidated statement of operations.

We capitalize the costs associated with the construction of cable transmission and distribution facilities, new customer installations and indirect costs associated with our phone service. Costs include direct labor and material, as well as certain indirect costs including capitalized interest. We perform periodic evaluations of the estimates used to determine the amount and extent that such costs are capitalized. Any changes to these estimates, which may be significant, are applied in the period in which the evaluations were completed. The costs of disconnecting service at a customer’s dwelling or reconnecting to a previously installed dwelling are charged as expense in the period incurred. Costs associated with subsequent installations of additional services not previously installed at a customer’s dwelling are capitalized to the extent such costs are incremental and directly attributable to the installation of such additional services. See Note 3.

Capitalized Software Costs

We account for internal-use software development and related costs in accordance with Accounting Standards Codification (“ASC”) 350-40-Intangibles-Goodwill and Other: Internal-Use Software. Software development and other related costs consist of external and internal costs incurred in the application development stage to purchase and implement associated software. Costs incurred in the development of application and infrastructure of the software is capitalized and will be amortized over our respective estimated useful life of 5 years. During the years ended December 31, 2016 and 2015, we wrote off approximately $3.3 million ($2.8 million of which were fully amortized) and $5.3 million ($4.5 million of which was fully amortized), respectively, of software development costs. Capitalized software had a net book value of $0.2 million and $0.7 million as of December 31, 2016 and 2015, respectively.

Marketing and Promotional Costs

Marketing and promotional costs are expensed as incurred and were $35.7 million, $31.9 million and $24.3 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Intangible Assets

Our cable systems operate under non-exclusive cable franchises, or franchise rights, granted by state and local governmental authorities for varying lengths of time. We acquired these cable franchises through acquisitions of cable systems and were accounted for using the purchase method of accounting. As of December 31, 2016, we held 501 franchises in areas located throughout the United States. The value of a franchise is derived from the economic benefits we receive from the right to solicit new customers and to market our products and services, including video, HSD and phone, in a specific market territory. We concluded that our franchise rights have an indefinite useful life since, among other things, there are no legal, regulatory, contractual, competitive, economic or other factors limiting the period over which these franchise rights contribute to our revenues and cash flows. Goodwill is the excess of the acquisition cost of an acquired entity over the fair value of the identifiable net assets acquired. In accordance with ASC 350 — Intangibles — Goodwill and Other (“ASC 350”), we do not amortize franchise rights and goodwill. Instead, such assets are tested annually for impairment or more frequently if impairment indicators arise.

We follow the provisions of ASC 350 to test our goodwill and franchise rights for impairment. We assess the fair values of our reporting unit using the Excess Earnings Method of the Income Approach as our discounted cash flow (“DCF”) methodology, under which the fair value of cable franchise rights are determined in a direct manner. We employ the Multi-Period Excess Earnings Method to calculate the fair values of our cable franchise rights, using unobservable inputs (Level 3). This assessment involves significant judgment, including certain assumptions and estimates that determine future cash flow expectations and other future benefits, which are consistent with the expectations of buyers and sellers of cable systems in determining fair value. These assumptions and estimates include discount rates, estimated growth rates, terminal growth rates, comparable company data, revenues per customer, market penetration as a percentage of homes passed and operating margin. We also consider market transactions, market valuations, research analyst estimates and other valuations using multiples of operating income before depreciation and amortization to confirm the reasonableness of fair values determined by the DCF methodology. We also employ the Greenfield model to corroborate the fair values of our cable franchise rights determined under the In-use Excess Earnings DCF methodology. Significant impairment in value resulting in impairment charges may result if the estimates and assumptions used in the fair value determination change in the future. Such impairments, if recognized, could potentially be material.

Based on the guidance outlined in ASC 350, we have determined that the unit of accounting or reporting unit, for testing goodwill and franchise rights is Mediacom Broadband. Comprising cable system clusters across several states, Mediacom Broadband is at the financial reporting level that is managed and reviewed by the corporate office (i.e., chief operating decision maker) including our determination as to how we allocate capital resources and utilize the assets. The reporting unit level also reflects the level at which the purchase method of accounting for our acquisitions was originally recorded.

In accordance with ASC 350, we are required to determine goodwill impairment using a two-step process. The first step compares the fair value of a reporting unit with our carrying amount, including goodwill. If the fair value of the reporting unit exceeds our carrying amount, goodwill of the reporting unit is considered not impaired and the second step is unnecessary. If the carrying amount of a reporting unit exceeds our fair value, the second step is performed to measure the amount of impairment loss, if any. The second step compares the implied fair value of the reporting unit’s goodwill, calculated using the residual method, with the carrying amount of that goodwill. If the carrying amount of the goodwill exceeds the implied fair value, the excess is recognized as an impairment loss.

The impairment test for our franchise rights and other intangible assets not subject to amortization consists of a comparison of the fair value of the intangible asset with its carrying value. If the carrying value of the intangible asset exceeds its fair value, the excess is recognized as an impairment loss.

Since our adoption of ASC 350 in 2002, we have not recorded any impairments as a result of our impairment testing. We completed our most recent impairment test as of October 1, 2016, which reflected no impairment of our franchise rights, goodwill or other intangible assets.

We could record impairments in the future if there are changes in the long-term fundamentals of our business, in general market conditions or in the regulatory landscape that could prevent us from recovering the carrying value of our long-lived intangible assets. The economic conditions affecting the U.S. economy, and how that may impact the fundamentals of our business, may have a negative impact on the fair values of the assets in our reporting unit.

In accordance with Accounting Standards Update No. 2010-28 — When to Perform Step 2 of the Goodwill Impairment Test for Reporting Units with Zero or Negative Carrying Amounts (a consensus of the FASB Emerging Issues Task Force), as of October 1, 2016 and 2015, we have evaluated whether there are any adverse qualitative factors surrounding our Mediacom Broadband reporting unit indicating that a goodwill impairment may exist. We do not believe that it is “more likely than not” that a goodwill impairment exists. As such, we have not performed Step 2 of the goodwill impairment test. As of both December 31, 2016 and 2015, the Mediacom Broadband reporting unit had a positive carrying amount.

The following table details changes in the carrying value of goodwill for the years ended December 31, 2016 and 2015 (dollars in thousands):


Balance - December 31, 2014	$	195,945
Acquisitions		—

Segment Reporting

ASC 280 — Segment Reporting (“ASC 280”) requires the disclosure of factors used to identify an enterprise’s reportable segments. Our operations are organized and managed on the basis of cable system clusters within our service area. Each cable system cluster derives revenues from the delivery of similar products and services to a customer base that is also similar. Each cable system cluster deploys similar technology to deliver our products and services, operates within a similar regulatory environment and has similar economic characteristics. We evaluated the criteria for aggregation under ASC 280 and believe that we meet each of the respective criteria set forth and accordingly, have identified broadband services as our one reportable segment.

Accounting for Derivative Instruments

We account for derivative instruments in accordance with ASC 815 — Derivatives and Hedging. These pronouncements require that all derivative instruments be recognized on the balance sheet at fair value. We enter into interest rate exchange agreements to fix the interest rate on a portion of our variable interest rate debt to reduce the potential volatility in our interest expense that would otherwise result from changes in market interest rates. Our derivative instruments are recorded at fair value and are included in other current assets, other assets and other liabilities of our consolidated balance sheet. Our accounting policies for these instruments are based on whether they meet our criteria for designation as hedging transactions, which include the instrument’s effectiveness, risk reduction and, in most cases, a one-to-one matching of the derivative instrument to our underlying transaction. Gains and losses from changes in fair values of derivatives that are not designated as hedges for accounting purposes are recognized in the consolidated statement of operations. We have no derivative financial instruments designated as hedges. Therefore, changes in fair value for the respective periods were recognized in the consolidated statement of operations.

Accounting for Asset Retirement

We adopted ASC 410 — Asset Retirement Obligations (“ASC 410”), on January 1, 2003. ASC 410 addresses financial accounting and reporting for obligations associated with the retirement of tangible long-lived assets and the associated asset retirement costs. We reviewed our asset retirement obligations to determine the fair value of such liabilities and if a reasonable estimate of fair value could be made. This entailed the review of leases covering tangible long-lived assets as well as our rights-of-way under franchise agreements. Certain of our franchise agreements and leases contain provisions that require restoration or removal of equipment if the franchises or leases are not renewed. Based on historical experience, we expect to renew our franchise or lease agreements. In the unlikely event that any franchise or lease agreement is not expected to be renewed, we would record an estimated liability. However, in determining the fair value of our asset retirement obligation under our franchise agreements, consideration will be given to the Cable Communications Policy Act of 1984, which generally entitles the cable operator to the “fair market value” for the cable system covered by a franchise, if renewal is denied and the franchising authority acquires ownership of the cable system or effects a transfer of the cable system to another person. Changes in these assumptions based on future information could result in adjustments to estimated liabilities.

Upon adoption of ASC 410, we determined that in certain instances, we are obligated by contractual terms or regulatory requirements to remove facilities or perform other remediation activities upon the retirement of our assets. We initially recorded a $1.8 million asset in property, plant and equipment and a corresponding liability of $1.8 million. As of both December 31, 2016 and 2015, the corresponding asset, net of accumulated amortization, was $0.

Accounting for Long-Lived Assets

In accordance with ASC 360 — Property, Plant and Equipment, we periodically evaluate the recoverability and estimated lives of our long-lived assets, including property and equipment and intangible assets subject to amortization, whenever events or changes in circumstances indicate that the carrying amount may not be recoverable or the useful life has changed. The measurement for such impairment loss is based on the fair value of the asset, typically based upon the future cash flows discounted at a rate commensurate with the risk involved. Unless presented separately, the loss is included as a component of either depreciation expense or amortization expense, as appropriate.

Programming Costs

We have various fixed-term carriage contracts to obtain programming for our cable systems from content suppliers whose compensation is generally based on a fixed monthly fee per video customer. These programming contracts are subject to negotiated renewal. Programming costs are recognized when we distribute the related programming. These programming costs are usually payable each month based on calculations performed by us and are subject to adjustments based on the results of periodic audits by the content suppliers. Historically, such audit adjustments have been immaterial to our total programming costs. Financial incentives, when received, are deferred within non-current liabilities in our consolidated balance sheets and recognized as a reduction of programming costs (which are a component of service costs in the consolidated statement of operations) over the carriage term of the programming contract.

Recent Accounting Pronouncements

In May 2014, the FASB issued ASU No. 2014-09 (“ASU 2014-09”) – Revenue from Contracts with Customers. The guidance states that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. An entity should also disclose sufficient information to enable users of financial statements to understand the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. This guidance supersedes most industry-specific guidance, including Statement of Financial Accounting Standards No. 51 – Financial Reporting by Cable Television Companies. ASU 2014-09 is effective for annual reporting periods beginning after December 15, 2016, including interim periods within that reporting period. Based on a preliminary assessment of certain revenue transactions performed to date, we expect that the new guidance will impact the timing of the recognition of installation revenue and commission expenses. Under the new guidance, these amounts will be recognized as revenue and expenses, respectively, over a period of time instead of immediately, as is being done under current practice. Installation revenues and commission expenses recorded in 2016 are each less than 2% of total revenues recorded in the same period. We are currently in the process of evaluating which method of transition will be utilized at adoption. We continue to assess all of the potential impacts that the adoption of ASU 2014-09 will have on our consolidated financial statements, including the development of new accounting policies, procedures and internal controls associated with the adoption of the standard.

In August 2014, the FASB issued new guidance that requires management to assess the Company’s ability to continue as a going concern and to provide related disclosures in certain circumstances. This guidance is effective for interim and fiscal years ending after December 15, 2016, with early adoption permitted. This guidance did not have a material impact on our financial position, operations or cash flows.

In April 2015 (as amended in August 2015), the FASB issued ASU No. 2015-03 (and ASU 2015-15) - Interest—Imputation of Interest (Subtopic 835-30) Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”). The purpose of this guidance is to simplify the presentation of debt issuance costs and requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. For public business entities, the amendments in this update are effective for financial statements issued for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. An entity should apply the new guidance on a retrospective basis, wherein the balance sheet of each individual period presented should be adjusted to reflect the period-specific effects of applying the new guidance. We adopted ASU 2015-03 and ASU 2015-15 as of January 1, 2016 and implemented retrospectively as of December 31, 2015. We reclassified $14.4 million of deferred financing costs from other assets, net to long-term debt, net (less current portion) as of December 31, 2016 in accordance with such guidance. We reclassified $20.2 million of deferred financing costs from other assets, net to long-term debt, net (less current portion) as of December 31, 2015 in accordance with such guidance. See Note 6.

In April 2015, the FASB issued ASU 2015-05 - Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) (“ASU 2015-05”). The objective of ASU 2015-05 is to address the concerns of stakeholders that the lack of guidance about a customer’s accounting for fees in a cloud computing arrangement leads to unnecessary cost and complexity when evaluating the accounting for those fees, as well as some diversity in practice. The amendments in ASU 2015-05 will help entities evaluate the accounting for fees

paid by a customer in a cloud computing arrangement by providing guidance as to whether an arrangement includes the sale or license of software. Examples of cloud computing arrangements include software as a service, platform as a service, infrastructure as a service, and other similar hosting arrangements. This guidance is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2015. We adopted this new guidance as of January 1, 2016 and determined that there was not a material impact to our operations.

In February 2016, the FASB issued ASU 2016-02 - Leases (Topic 842) (“ASU 2016-02”). The objective of ASU 2016-02 is to address the concerns to increase the transparency around lease obligations. To address these concerns, previously unrecorded off-balance sheet obligations will now be brought more prominently to light by presenting lease liabilities on the face of the balance sheet. Accompanied by enhanced qualitative and quantitative disclosures in the notes to the financial statements, financial statement users will be able to more accurately compare information from one company to another. This guidance is effective for annual periods, including interim periods within those annual periods, beginning after December 15, 2018. We have not completed our evaluation of this new guidance.

In August 2016, the FASB issued ASU 2016-15 – Statement of Cash Flows – Clarification of Certain Cash Receipts and Cash Payments. (“ASU 2016-15”). Stakeholders indicated that there is diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows under Topic 230, Statement of Cash Flows, and other topics. ASU 2016-15 addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice. The amendments in ASU 2016-15 are effective for public business entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. We do not expect ASU 2016-15 will have a material impact on financial position, operations or cash flows upon adoption.

4. FAIR VALUE

The tables below set forth our financial assets and liabilities measured at fair value on a recurring basis using a market-based approach. Our financial assets and liabilities, all of which represent interest rate exchange agreements (which we refer to as “interest rate swaps”) have been categorized according to the three-level fair value hierarchy established by ASC 820 – Fair Value Measurement – (“ASC 820”), which prioritizes the inputs used in measuring fair value, as follows (dollars in thousands):

•

Level 1 — Quoted market prices in active markets for identical assets or liabilities.

•

Level 2 — Observable market based inputs or unobservable inputs that are corroborated by market data.

•

Level 3 — Unobservable inputs that are not corroborated by market data.


	Fair Value as of December 31, 2016
	Level 1		Level 2		Level 3		Total
Assets
Interest rate exchange agreements	$	—	$	1,089	$	—	$	1,089

Interest rate exchange agreements	$	—	$	1,818	$	—	$	1,818

Liabilities
Interest rate exchange agreements	$	—	$	3,695	$	—	$	3,695

The fair value of our interest rate swaps represents the estimated amount that we would receive or pay to terminate such agreements, taking into account projected interest rates, based on quoted London Interbank Offered Rate (“LIBOR”) futures and the remaining time to maturity. While our interest rate swaps are subject to contractual terms that provide for the net settlement of transactions with counterparties, we do not offset assets and liabilities under these agreements for financial statement presentation purposes, and assets and liabilities are reported on a gross basis.

As of December 31, 2016, we recorded a long-term asset of $1.1 million, a current liability in accounts payable, accrued expenses and other current liabilities of $1.8 million and no current asset or long-term liability. As of December 31, 2015, we recorded a long-term asset of $1.8 million, a current liability in accounts payable, accrued expenses and other current liabilities of $3.7 million and no current asset or long-term liability.

As a result of the changes in the mark-to-market valuations on our interest rate swaps, we recorded net gains on derivatives of $1.2 million, $9.2 million and $23.2 million for the years ended December 31, 2016, 2015 and 2014, respectively.

Bank Credit Facility

As of December 31, 2016, we maintained a $1.384 billion bank credit facility (the “credit facility”), comprising:

•

$368.5 million of revolving credit commitments, which expire on October 10, 2019;

•

$143.9 million of outstanding borrowings under Term Loan A, which mature on January 15, 2021;

•

$579.0 million of outstanding borrowings under Term Loan H, which mature on January 29, 2021; and

•

$292.5 million of outstanding borrowings under Term Loan J, which mature on June 30, 2021.

The credit facility is collateralized by our ownership interests in our operating subsidiaries and is guaranteed by us on a limited recourse basis to the extent of such ownership interests. As of December 31, 2016, we had the ability to repay all outstanding debt under the credit facility at par value any time prior to maturity. As of December 31, 2016, the credit agreement governing the credit facility (the “credit agreement”) required our operating subsidiaries to maintain a total leverage ratio (as defined in the credit agreement) of no more than 5.0 to 1.0 and an interest coverage ratio (as defined in the credit agreement) of no less than 2.0 to 1.0. For all periods through December 31, 2016, our operating subsidiaries were in compliance with all covenants under the credit agreement.

Revolving Credit Commitments

On October 10, 2014, we terminated our existing revolving credit commitments and, on the same date, entered into an incremental facility agreement that provided for $216.0 million of new revolving credit commitments, which are scheduled to expire on October 10, 2019. On December 9, 2014, August 12, 2015 and November 23, 2015, we entered into incremental facility agreements that provided for an additional $40.0 million, $25.0 million and $87.5 million of revolving credit commitments, respectively.

Borrowings under our revolving credit commitments bear interest at a floating rate or rates equal to, at our discretion, LIBOR plus a margin ranging from 2.00% to 2.75%, or the Prime Rate plus a margin ranging from 1.00% to 1.75%. Commitment fees on the unused portion of our revolving credit commitments are payable at a rate of 0.50% or 0.63%. The applicable margin and commitment fees charged are determined by certain financial ratios pursuant to the credit agreement.

As of December 31, 2016, we had $246.2 million of unused revolving credit commitments, all of which were available to be borrowed and used for general corporate purposes, after giving effect to $112.6 million of outstanding loans and $9.7 million of letters of credit issued to various parties as collateral.

Term Loan A

On December 17, 2015, we entered into an incremental facility agreement that provided for a new term loan in the original principal amount of $151.5 million (“Term Loan A”). Term Loan A matures on January 15, 2021 and, since March 31, 2016, has been subject to quarterly principal payments of $1.9 million, representing 1.25% of the original principal amount, with a final payment at maturity of $113.6 million, representing 75.00% of the original principal amount.

Borrowings under Term Loan A bear interest at a floating rate or rates equal to, at our discretion, LIBOR plus a margin ranging from 2.25% to 3.50%, or the Prime Rate plus a margin ranging from 1.25% to 2.50%. The applicable margin and commitment fees charged are determined by certain financial ratios pursuant to the credit agreement.

Term Loan H

On May 29, 2013, we entered into an incremental facility agreement that provided for a new term loan in the original principal amount of $600.0 million (“Term Loan H”). Term Loan H matures on January 29, 2021 and, since September 30, 2013, has been subject to quarterly principal payments of $1.5 million, representing 0.25% of the original principal amount, with a final payment at maturity of $555.0 million, representing 92.5% of the original principal amount.

Borrowings under Term Loan H bear interest at a floating rate or rates equal to, at our discretion, LIBOR plus a margin of 2.50% (subject to a minimum LIBOR of 0.75%), or the Prime Rate plus a margin of 1.50% (subject to a minimum Prime Rate of 1.75%).

Term Loan J

On June 20, 2014, we entered into an amended and restated credit agreement that, among other things, provided for a new term loan in the original principal amount $300.0 million (“Term Loan J”). Term Loan J matures on June 30, 2021 and, since September 30, 2014, has been subject to quarterly principal payments of $0.8 million, representing 0.25% of the original principal amount, with a final payment at maturity of $279.8 million, representing 93.25% of the original principal amount.

Borrowings under Term Loan J bear interest at a floating rate or rates equal to, at our discretion, LIBOR plus a margin of 2.75% or 3.00% (subject to a minimum LIBOR of 0.75%), or the Prime Rate plus a margin of 1.75% or 2.00% (subject to a minimum Prime Rate of 1.75%). The applicable margin charged is determined by certain financial ratios pursuant to the credit agreement.

Interest Rate Swaps

We have entered into several interest rate exchange agreements (which we refer to as “interest rate swaps”) with various banks to fix the variable rate on a portion of our borrowings under the credit facility to reduce the potential volatility in our interest expense that may result from changes in market interest rates. Our interest rate swaps have not been designated as hedges for accounting purposes, and have been accounted for on a mark-to-market basis as of, and for the years ended, December 31, 2016, 2015 and 2014. As of December 31, 2016, we had current interest rate swaps that fixed the variable portion of $600 million of borrowings at a rate of 1.5%, all of which are scheduled to expire during December 2018.

As of December 31, 2016, the weighted average interest rate on outstanding borrowings under the credit facility, including the effect of our interest rate swaps, was 3.5%.

Senior Notes

As of December 31, 2016, we had $500.0 million of outstanding senior notes, comprising $200.0 million of 5¹⁄₂% senior notes due April 2021 (the “5¹⁄₂% Notes”), and $300.0 million of 6³⁄₈%senior notes due April 2023 (the “6³⁄₈% Notes”).

Our senior notes are unsecured obligations and, as of December 31, 2016, the indentures governing our senior notes (the “indentures”) limits the incurrence of additional indebtedness based upon a maximum debt to operating cash flow ratio (as defined in the indentures) of 8.5 to 1.0. For all periods through December 31, 2016, we were in compliance with all of the covenants under the indentures.

5¹⁄₂% Notes

On March 17, 2014, we issued the 5¹⁄₂% Notes in the aggregate principal amount of $200.0 million. Net proceeds from the 5¹⁄₂% Notes funded a partial repayment of certain previously existing term loans.

As a percentage of par value, the 5¹⁄₂% Notes are redeemable at 102.750% commencing April 15, 2017, 101.375% commencing April 15, 2018 and at par value commencing April 15, 2019.

6³⁄₈%Notes

On August 28, 2012, we issued the 6³⁄₈%Notes in the aggregate principal amount of $300.0 million. Net proceeds from the 6³⁄₈% Notes were used to fund, in part, the redemption of certain previously existing senior notes.

As a percentage of par value, the 6³⁄₈%Notes are redeemable at 103.188% commencing April 1, 2018, 102.125% commencing April 1, 2019, 101.063% commencing April 1, 2020 and at par value commencing April 1, 2021.

Loss on Early Extinguishment of Debt

Loss on early extinguishment of debt totaled $1.2 million, $4.4 million and $0.3 million for the years ended December 31, 2016, 2015 and 2014, respectively, which represented the write-off of unamortized deferred financing costs as a result of the repayment of certain previously existing term loans under the credit facility.

Deferred Financing Costs

We adopted ASU 2015-03 and ASU 2015-15 as of January 1, 2016, and implemented retrospectively as of December 31, 2015. In accordance with such guidance, we reclassified $14.4 million and $20.2 million of deferred financing costs from other assets, net to long-term debt, net (less current portion) as of December 31, 2016 and 2015, respectively.

Debt Ratings

MCC’s corporate credit ratings are currently Ba3 by Moody’s, with a positive outlook, and BB by Standard and Poor’s (“S&P”), with a stable outlook, and our senior unsecured ratings are currently B2 by Moody’s, with a positive outlook, and B+ by S&P, with a stable outlook. There are no covenants, events of default, borrowing conditions or other terms in the credit agreement or indentures that are based on changes in our credit rating assigned by any rating agency.

Fair Value and Debt Maturities

The fair values of our senior notes and outstanding debt under the credit facility (which were calculated based upon market prices of such issuances in an active market when available) were as follows as of December 31, 2016 and 2015 (dollars in thousands):

Programming Costs

Programming Costs

We have various fixed-term carriage contracts to obtain programming for our cable systems from content suppliers whose compensation is generally based on a fixed monthly fee per video customer. These programming contracts are subject to negotiated renewal. Programming costs are recognized when we distribute the related programming. These programming costs are usually payable each month based on calculations performed by us and are subject to adjustments based on the results of periodic audits by the content suppliers. Historically, such audit adjustments have been immaterial to our total programming costs. Financial incentives, when received, are deferred within non-currentliabilities in our consolidated balance sheets and recognized as a reduction of programming costs (which are a component of service costs in the consolidated statement of operations) over the carriage term of the programming contract.
