Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying Condensed Consolidated Financial Statements include Belden Inc. and all of its subsidiaries (the Company, us, we, or our). We eliminate all significant affiliate accounts and transactions in consolidation. The accompanying Condensed Consolidated Financial Statements presented as of any date other than December 31, 2019: • Are prepared from the books and records without audit, and • Are prepared in accordance with the instructions for Form 10-Q and do not include all of the information required by accounting principles generally accepted in the United States for complete statements, but • Include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the financial statements. These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Supplementary Data contained in our 2019 Annual Report on Form 10-K. Business Description We are a global supplier of specialty networking solutions built around two global business platforms - Enterprise Solutions and Industrial Solutions. Our comprehensive portfolio of solutions enables customers to transmit and secure data, sound, and video for mission critical applications across complex enterprise and industrial environments. Effective January 1, 2020, we transferred our West Penn Wire business and multi-conductor product lines from the Enterprise Solutions segment to the Industrial Solutions segment as a result of a shift in responsibilities among the segments. We have recast the prior period segment information to conform to the change in the composition of reportable segments. Reporting Periods Our fiscal year and fiscal fourth quarter both end on December 31. Our fiscal first quarter ends on the Sunday falling closest to 91 days after December 31, which was March 29, 2020, the 89th day of our fiscal year 2020. Our fiscal second and third quarters each have 91 days. The six months ended June 28, 2020 and June 30, 2019 included 180 and 181 days, respectively. Fair Value Measurement Accounting guidance for fair value measurements specifies a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources or reflect our own assumptions of market participant valuation. The hierarchy is broken down into three levels based on the reliability of the inputs as follows: • Level 1 – Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities; • Level 2 – Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets, or financial instruments for which significant inputs are observable, either directly or indirectly; and • Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. As of and during the three and six months ended June 28, 2020 and June 30, 2019, we utilized Level 1 inputs to determine the fair value of cash equivalents, and we utilized Level 2 and Level 3 inputs to determine the fair value of net assets acquired in business combinations (see Note 3) and for impairment testing (see Notes 4 and 10). We did not have any transfers between Level 1 and Level 2 fair value measurements during the six months ended June 28, 2020 and June 30, 2019. Cash and Cash Equivalents We classify cash on hand and deposits in banks, including commercial paper, money market accounts, and other investments with an original maturity of three months or less, that we hold from time to time, as cash and cash equivalents. We periodically have cash equivalents consisting of short-term money market funds and other investments. As of June 28, 2020, we did not have any such cash equivalents on hand. The primary objective of our investment activities is to preserve our capital for the purpose of funding operations. We do not enter into investments for trading or speculative purposes. During the six months ended June 28, 2020, we paid the sellers of Snell Advanced Media (SAM) the full earnout consideration of $31.4 million in cash as per the purchase agreement. SAM was acquired on February 8, 2018 and is included in the Grass Valley disposal group. Due to the initial uncertainties arising from the COVID-19 pandemic and out of an abundance of caution, we borrowed $190.0 million and subsequently repaid $100.0 million under our Revolving Credit Agreement during the second quarter. See Note 12. Contingent Liabilities We have established liabilities for environmental and legal contingencies that are probable of occurrence and reasonably estimable, the amounts of which are currently not material. We accrue environmental remediation costs based on estimates of known environmental remediation exposures developed in consultation with our environmental consultants and legal counsel. We are, from time to time, subject to routine litigation incidental to our business. These lawsuits primarily involve claims for damages arising out of the use of our products, allegations of patent or trademark infringement, and litigation and administrative proceedings involving employment matters and commercial disputes. Based on facts currently available, we believe the disposition of the claims that are pending or asserted will not have a materially adverse effect on our financial position, results of operations, or cash flow. As of June 28, 2020, we were party to standby letters of credit, bank guaranties, and surety bonds totaling $7.7 million, $4.1 million, and $3.3 million, respectively. Revenue Recognition We recognize revenue consistent with the principles as outlined in the following five step model: (1) identify the contract with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) each performance obligation is satisfied. See Note 2. Subsequent Events We evaluated subsequent events after the balance sheet date through the financial statement issuance date for appropriate accounting and disclosure. See Note 19. Noncontrolling Interest We have a 51% ownership percentage in a joint venture with Shanghai Hi-Tech Control System Co, Ltd (Hite). The purpose of the joint venture is to develop and provide certain Industrial Solutions products and integrated solutions to customers in China. Belden and Hite are committed to fund $1.53 million and $1.47 million, respectively, to the joint venture in the future. The joint venture is determined to not have sufficient equity at risk; therefore, it is considered a variable interest entity. We have determined that Belden is the primary beneficiary of the joint venture, due to both our ownership percentage and our control over the activities of the joint venture that most significantly impact its economic performance based on the terms of the joint venture agreement with Hite. Because Belden is the primary beneficiary of the joint venture, we have consolidated the joint venture in our financial statements. The results of the joint venture attributable to Hite’s ownership are presented as net income (loss) attributable to noncontrolling interest in the Condensed Consolidated Statements of Operations. The joint venture is not material to our Condensed Consolidated financial statements as of or for the periods ended June 28, 2020 and June 30, 2019. Furthermore, certain subsidiaries of our Opterna business, which we acquired in April of 2019 include noncontrolling interests. Because we have a controlling financial interest in these subsidiaries, they are consolidated into our financial statements. The results of these subsidiaries were consolidated into our financial statements as of the acquisition date.

Revenue from Contract with Customer [Abstract]
Revenues	Revenues Revenues are recognized when control of the promised goods or services is transferred to our customers and in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services. Taxes collected from customers and remitted to governmental authorities are not included in our revenues. The following tables present our revenues disaggregated by major product category.

We also generate revenues from providing support and professional services. We sell our products to distributors, end-users, installers, and directly to original equipment manufacturers. At times, we enter into arrangements that involve the delivery of multiple performance obligations. For these arrangements, revenue is allocated to each performance obligation based on its relative selling price and recognized when or as each performance obligation is satisfied. Most of our performance obligations related to the sale of products are satisfied at a point in time when control of the product is transferred based on the shipping terms of the arrangement. Generally, we determine relative selling price using the prices charged to customers on a standalone basis. The amount of consideration we receive and revenue we recognize varies due to rebates, returns, and price adjustments. We estimate the expected rebates, returns, and price adjustments based on an analysis of historical experience, anticipated sales demand, and trends in product pricing. We adjust our estimate of revenue at the earlier of when the most likely amount of consideration we expect to receive changes or when the consideration becomes fixed. Adjustments to revenue for performance obligations satisfied in prior periods were not significant during the three and six months ended June 28, 2020 and June 30, 2019. The following table presents estimated and accrued variable consideration: June 28, 2020 June 30, 2019 (in thousands) Accrued rebates $ 20,261 $ 24,152 Accrued returns 18,529 9,071 Price adjustments recognized against gross accounts receivable 19,371 29,709 Depending on the terms of an arrangement, we may defer the recognition of some or all of the consideration received because we have to satisfy a future obligation. Consideration allocated to support services under a support and maintenance contract is typically paid in advance and recognized ratably over the term of the service. Consideration allocated to professional services is typically recognized when or as the services are performed depending on the terms of the arrangement. As of June 28, 2020, total deferred revenue was $68.6 million, and of this amount, $49.9 million is expected to be recognized within the next twelve months, and the remaining $18.7 million is long-term and is expected to be recognized over a period greater than twelve months. The following table presents deferred revenue activity: 2020 2019 (In thousands) Beginning balance $ 70,070 $ 72,358 New deferrals 23,830 26,033 Revenue recognized (24,415) (32,168) Balance at the end of the first quarter 69,485 66,223 New deferrals 21,322 21,892 Revenue recognized (22,200) (24,807) Balance at the end of the second quarter $ 68,607 $ 63,308 We expense sales commissions as incurred when the duration of the related revenue arrangement is one year or less. We capitalize sales commissions in other current and long-lived assets on our balance sheet when the original duration of the related revenue arrangement is longer than one year, and we amortize it over the related revenue arrangement period. Total capitalized sales commissions was $4.6 million as of June 28, 2020 and $3.3 million as of June 30, 2019.

Acquisitions

Business Combinations [Abstract]
Acquisitions	Acquisitions Special Product Company On December 6, 2019, we purchased substantially all the assets, and assumed certain specified liabilities of Special Product Company (SPC) for a preliminary purchase price of $22.5 million. SPC, based in Kansas City, Kansas, is a leading designer, manufacturer, and seller of outdoor cabinet products for optical fiber cable installations. The results of SPC have been included in our Condensed Consolidated Financial Statements from December 6, 2019, and are reported within the Enterprise Solutions segment. The acquisition of SPC was not material to our financial position or results of operations. Opterna International Corp. We acquired 100% of the shares of Opterna International Corp. (Opterna) on April 15, 2019 for a purchase price, net of cash acquired, of $51.7 million. Of the $51.7 million purchase price, $45.9 million was paid with cash on hand. The acquisition included a potential earnout, which is based upon future Opterna financial targets through April 15, 2021. The maximum earnout consideration is $25.0 million, but based upon a third party valuation specialist using certain assumptions in a discounted cash flow model, the estimated fair value of the earnout included in the purchase price is $5.8 million. Opterna is an international fiber optics solutions business based in Sterling, Virginia, which designs and manufactures a range of complementary fiber connectivity, cabinet, and enclosure products used in optical networks. The results of Opterna have been included in our Condensed Consolidated Financial Statements from April 15, 2019, and are reported within the Enterprise Solutions segment. Certain subsidiaries of Opterna include noncontrolling interests. Because Opterna has a controlling financial interest in these subsidiaries, they are consolidated into our financial statements. The results that are attributable to the noncontrolling interest holders are presented as net income attributable to noncontrolling interests in the Condensed Consolidated Statements of Operations. An immaterial amount of Opterna's annual revenues are generated from transactions with the noncontrolling interests. On October 25, 2019, we purchased the noncontrolling interest of one subsidiary for a purchase price of $0.8 million; of which $0.4 million was paid at closing and the remaining $0.4 million will be paid in 2021. The following table summarizes the estimated fair values of the assets acquired and the liabilities assumed as of April 15, 2019 (in thousands): Receivables $ 5,308 Inventory 7,359 Prepaid and other current assets 566 Property, plant, and equipment 1,328 Intangible assets 28,000 Goodwill 35,057 Deferred income taxes 80 Operating lease right-to-use assets 2,204 Other long-lived assets 2,070 Total assets acquired $ 81,972 Accounts payable $ 4,847 Accrued liabilities 4,301 Long-term deferred tax liability 6,813 Long-term operating lease liability 1,923 Other long-term liabilities 7,152 Total liabilities assumed $ 25,036 Net assets 56,936 Noncontrolling interests 5,195 Net assets attributable to Belden $ 51,741 We did not record any material measurement-period adjustments in the three and six months ended June 28, 2020. A single estimate of fair value results from a complex series of judgments about future events and uncertainties and relies heavily on estimates and assumptions. The judgments we have used in estimating the fair values assigned to each class of acquired assets and assumed liabilities could materially affect the results of our operations. The fair value of acquired receivables is $5.3 million, which is equivalent to its gross contractual amount. For purposes of the above allocation, we based our estimate of the fair values for the acquired inventory, intangible assets, and noncontrolling interests on valuation studies performed by a third party valuation firm. We have estimated a fair value adjustment for inventories based on the estimated selling price of the work-in-process and finished goods acquired at the closing date less the sum of the costs to complete the work-in-process, the costs of disposal, and a reasonable profit allowance for our post acquisition selling efforts. We used various valuation methods including discounted cash flows, lost income, excess earnings, and relief from royalty to estimate the fair value of the identifiable intangible assets (Level 3 valuation). Our estimate of the fair values for the noncontrolling interests were based on the comparable EBITDA multiple valuation technique (Level 3 valuation). Goodwill and other intangible assets reflected above were determined to meet the criteria for recognition apart from tangible assets acquired and liabilities assumed. The goodwill is primarily attributable to expansion of product offerings in the optical fiber market. Our tax basis in the acquired goodwill is zero. The intangible assets related to the acquisition consisted of the following: Fair Value Amortization Period (In thousands) (In years) Intangible assets subject to amortization: Developed technologies $ 3,400 5.0 Customer relationships 22,800 15.0 Sales backlog 1,300 0.5 Trademarks 500 2.0 Total intangible assets subject to amortization $ 28,000 Intangible assets not subject to amortization: Goodwill $ 35,057 n/a Total intangible assets not subject to amortization $ 35,057 Total intangible assets $ 63,057 Weighted average amortization period 12.9 The amortizable intangible assets reflected in the table above were determined by us to have finite lives. The useful life for the developed technology intangible asset was based on the estimated time that the technology provides us with a competitive advantage and thus approximates the period and pattern of consumption of the intangible asset. The useful life for the customer relationship intangible asset was based on our forecasts of estimated sales from recurring customers. The useful life of the backlog intangible asset was based on our estimate of when the ordered items would ship and control of the items transfers. The useful life for the trademarks was based on the period of time we expect to continue to go to market using the trademarks. The following table illustrates the unaudited pro forma effect on operating results as if the Opterna acquisition had been completed as of January 1, 2018. Three Months Ended Six Months Ended June 30, 2019 June 30, 2019 (In thousands, except per share data) (Unaudited) Revenues $ 548,352 $ 1,057,108 Net income from continuing operations attributable to Belden common stockholders 35,150 54,393 Diluted income from continuing operations per share attributable to Belden common stockholders $ 0.89 $ 1.38 The above unaudited pro forma financial information is presented for informational purposes only and does not purport to represent what our results of operations would have been had we completed the acquisition on the date assumed, nor is it necessarily indicative of the results that may be expected in future periods. Pro forma adjustments exclude cost savings from any synergies resulting from the acquisition. FutureLink

Discontinued Operations and Disposal Groups [Abstract]
Discontinued Operations	Discontinued Operations We classify assets and liabilities as held for sale (disposal group) when management, having the authority to approve the action, commits to a plan to sell the disposal group, the sale is probable within one year, and the disposal group is available for immediate sale in its present condition. We also consider whether an active program to locate a buyer has been initiated, whether the disposal group is marketed actively for sale at a price that is reasonable in relation to its current fair value, and whether actions required to complete the plan indicate that it is unlikely that significant changes to the plan will be made or that the plan will be withdrawn. During the fourth quarter of 2019, we committed to a plan to sell Grass Valley, and at such time, met all of the criteria to classify the assets and liabilities of this business as held for sale. Furthermore, we determined a divestiture of Grass Valley represents a strategic shift that is expected to have a major impact on our operations and financial results. As a result, the Grass Valley disposal group, which was included in our Enterprise Solutions segment, is reported within discontinued operations. The Grass Valley disposal group excludes certain Grass Valley pension liabilities that we are retaining. We also ceased depreciating and amortizing the assets of the disposal group once they met the held for sale criteria during the fourth quarter of 2019. We wrote down the carrying value of Grass Valley and recognized asset impairments totaling $89.8 million and $113.0 million in the three and six months e nded June 28, 2020, respectively. We determined the estimated fair values of the assets and of the reporting unit by calculating the present values of their estimated future cash flows. On July 2, 2020, we completed the sale of Grass Valley - see further discussion in Note 19. The following table summarizes the operating results of the disposal group for the three and six months ended June 28, 2020 and June 30, 2019, respectively: Three Months Ended Six Months Ended June 28, 2020 June 30, 2019 June 28, 2020 June 30, 2019 (In thousands) Revenues $ 56,812 $ 89,178 $ 107,861 $ 176,213 Cost of sales (33,989) (53,227) (69,191) (102,390) Gross profit 22,823 35,951 38,670 73,823 Selling, general and administrative expenses (19,342) (20,030) (36,861) (44,861) Research and development expenses (5,974) (10,259) (14,473) (21,166) Amortization of intangibles — (3,299) — (8,477) Asset impairment of discontinued operations (89,810) — (113,007) — Interest expense, net (214) (207) (420) (413) Non-operating pension cost (111) (55) (196) (111) Income (loss) before taxes $ (92,628) $ 2,101 $ (126,287) $ (1,205) The disposal group had capital expenditures of approximately $8.5 million a nd $16.4 million during the three and six months ended June 28, 2020, respectively; and $8.7 million and $14.5 million during the three and six months ended June 30, 2019, respectively. The disposal group recognized credits to stock-based compensation of $0.0 million and $0.9 million during the three and six months ended June 28, 2020, respectively. The disposal group incurred stock based compensation expense of $0.3 million and $0.6 million during the three and six months ended June 30, 2019, respectively. The disposal group did not have any significant non-cash charges for investing activities during the three and six months ended June 28, 2020 or June 30, 2019. The following table provides the major classes of assets and liabilities of the disposal group as of June 28, 2020 and December 31, 2019, respectively: June 28, 2020 December 31, 2019 (In thousands) Assets: Cash and cash equivalents $ 33,337 $ 18,405 Receivables, net 90,492 117,386 Inventories, net 49,997 55,002 Other current assets 38,626 35,187 Plant, property, and equipment, less accumulated depreciation 65,056 61,233 Operating lease right-of-use assets 15,631 16,902 Goodwill 26,067 26,707 Intangible assets, less accumulated depreciation 150,214 143,459 Deferred income taxes 58,148 59,560 Other long-lived assets 12,201 21,652 Impairment of disposal group (289,447) (180,358) Total Assets of discontinued operations $ 250,322 $ 375,135 Liabilities: Accounts payable $ 42,482 $ 52,425 Accrued liabilities 38,816 83,349 Postretirement benefits 4,976 6,224 Deferred income taxes 2,404 2,740 Long-term operating lease liabilities 18,745 20,459 Other long-term liabilities 2,250 5,082 Total Liabilities of discontinued operations $ 109,673 $ 170,279 The disposal group also had $11.5 million and $42.3 million of accumulated other comprehensive losses as of June 28, 2020 and December 31, 2019, respectively.

Reportable Segments

Reportable Segments	6 Months Ended
	Jun. 28, 2020
Segment Reporting [Abstract]
Reportable Segments	Reportable Segments We are organized around two global business platforms: Enterprise Solutions and Industrial Solutions. Each of the global business platforms represents a reportable segment. Effective January 1, 2020, we transferred our West Penn Wire business and multi-conductor product lines from the Enterprise Solutions segment to the Industrial Solutions segment as a result of a shift in responsibilities among the segments. We have recast the prior period segment information to conform to the change in the composition of reportable segments. The key measures of segment profit or loss are Segment Revenues and Segment EBITDA. Segment Revenues represent non-affiliate revenues and include revenues that would have otherwise been recorded by acquired businesses as independent entities but were not recognized in our Condensed Consolidated Statements of Operations and Comprehensive Income due to the effects of purchase accounting and the associated write-down of acquired deferred revenue to fair value. Segment EBITDA excludes certain items, including depreciation expense; amortization of intangibles; asset impairment; severance, restructuring, and acquisition integration costs; purchase accounting effects related to acquisitions, such as the adjustment of acquired inventory and deferred revenue to fair value; and other costs. We allocate corporate expenses to the segments for purposes of measuring Segment EBITDA. Corporate expenses are allocated on the basis of each segment’s relative EBITDA prior to the allocation. Our measure of segment assets does not include cash, goodwill, intangible assets, deferred tax assets, or corporate assets. All goodwill is allocated to reporting units of our segments for purposes of impairment testing.

Earnings Per Share [Abstract]
Income per Share	Income (loss) per Share The following table presents the basis for the income (loss) per share computations: Three Months Ended Six Months Ended June 28, 2020 June 30, 2019 June 28, 2020 June 30, 2019 (In thousands) Numerator: Income from continuing operations $ 3,173 $ 41,395 $ 18,064 $ 69,330 Less: Net income (loss) attributable to noncontrolling interest 24 90 (6) 66 Less: Preferred stock dividends — 8,733 — 17,466 Income from continuing operations attributable to Belden common stockholders 3,149 32,572 18,070 51,798 Add: Income (loss) from discontinued operations, net of tax (71,054) 895 (97,164) (1,862) Net income (loss) attributable to Belden common stockholders $ (67,905) $ 33,467 $ (79,094) $ 49,936 Denominator: Weighted average shares outstanding, basic 44,557 39,389 44,969 39,405 Effect of dilutive common stock equivalents 108 222 128 230 Weighted average shares outstanding, diluted 44,665 39,611 45,097 39,635 For the three and six months ended June 28, 2020, diluted weighted average shares outstanding exclude outstanding equity awards of 1.7 million and 1.5 million, respectively, which are anti-dilutive. In addition, for both the three and six months ended June 28, 2020, diluted weighted average shares outstanding do not include outstanding equity awards of 0.4 million because the related performance conditions have not been satisfied. For the three and six months ended June 30, 2019, diluted weighted average shares outstanding exclude outstanding equity awards of 1.2 million and 1.1 million, respectively, which are anti-dilutive. In addition, for both the three and six months ended June 30, 2019, diluted weighted average shares outstanding do not include outstanding equity awards of 0.3 million because the related performance conditions have not been satisfied. Furthermore, for both the three and six months ended June 30, 2019, diluted weighted average shares outstanding do not include the impact of preferred shares that were converted into 6.9 million common shares, because deducting the preferred stock dividends from net income was more dilutive. For purposes of calculating basic earnings per share, unvested restricted stock units are not included in the calculation of basic weighted average shares outstanding until all necessary conditions have been satisfied and issuance of the shares underlying the restricted stock units is no longer contingent. Necessary conditions are not satisfied until the vesting date, at which time holders of our restricted stock units receive shares of our common stock. For purposes of calculating diluted earnings per share, unvested restricted stock units are included to the extent that they are dilutive. In determining whether unvested restricted stock units are dilutive, each issuance of restricted stock units is considered separately. Once a restricted stock unit has vested, it is included in the calculation of both basic and diluted weighted average shares outstanding.

Credit Loss [Abstract]
Credit Loss	Credit Losses Effective January 1, 2020, we adopted ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments prospectively. This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial instruments, including trade receivables. The amendment requires entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivables that are current or not yet due, which were not considered under the previous accounting guidance. Upon adoption, we recorded a noncash cumulative effect adjustment to retained earnings of $2.9 million. Of this amount, $1.0 million related to our continuing operations and $1.9 million related to our discontinued operations. We are exposed to credit losses primarily through sales of products and services. Our expected loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of customers' trade accounts receivables. Due to the short-term nature of such receivables, the estimate of amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances and the financial condition of customers. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. Our monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible. Estimates are used to determine the allowance, which is based upon an assessment of anticipated payments as well as other historical, current and future information that is reasonably available. The following table presents the activity in the allowance for doubtful accounts for our continuing operations for the three and six months ended June 28, 2020 (in thousands).

Leases [Abstract]
Leases	Leases We have operating and finance leases for properties, including manufacturing facilities, warehouses, and office space; as well as vehicles and certain equipment. We make certain judgments in determining whether a contract contains a lease in accordance with ASU 2016-02. Our leases have remaining lease terms of less than 1 year to 16 years; some of which include extension and termination options for an additional 15 years or within 1 year, respectively. We do not assume renewals in our determination of the lease term unless the renewals are deemed to be reasonably certain as of the commencement date of the lease. Our lease agreements do not contain any material residual value guarantees or material variable lease payments. We have entered into various short-term operating leases with an initial term of twelve months or less. These leases are not recorded on our balance sheet, and for the three and six months ended June 28, 2020 and June 30, 2019, the rent expense for short-term leases was not material. We have certain property and equipment lease contracts that may contain lease and non-lease components, and we have elected to utilize the practical expedient to account for these components together as a single combined lease component. As the rate implicit in most of our leases is not readily determinable, we use the incremental borrowing rate to determine the present value of the lease payments, which is unique to each leased asset, and is based upon the term of the lease, commencement date of the lease, local currency of the leased asset, and the credit rating of the legal entity leasing the asset.

Long-Lived Assets	Long-Lived Assets Depreciation and Amortization Expense We recognized depreciation expense of $10.3 million and $20.6 million in the three and six months ended June 28, 2020, respectively. We recognized depreciation expense of $9.9 million and $20.0 million in the three and six ended June 30, 2019, respectively. We recognized amortization expense related to our intangible assets of $16.4 million and $32.9 million in the three and six months ended June 28, 2020, respectively. We recognized amortization expense related to our intangible assets of $19.1 million and $37.4 million in the three and six ended June 30, 2019, respectively. Interim Impairment Test Due to equity market conditions during the three and six months ended June 28, 2020, we conducted an interim impairment test. We determined that the carrying values of our definite-lived assets were recoverable; therefore, we did not record any impairment charges related to these assets. Goodwill is tested for impairment at the reporting unit level, and we conducted an interim impairment test for all of our reporting units. A reporting unit is an operating segment, or a business unit one level below an operating segment if discrete financial information for that business is prepared and regularly reviewed by segment management. However, components within an operating segment are aggregated as a single reporting unit if they have similar economic characteristics. We determined that each of our reportable segments (Enterprise Solutions and Industrial Solutions) represents an operating segment. Within those operating segments, we have identified reporting units based on whether there is discrete financial information prepared that is regularly reviewed by segment management. When we evaluate goodwill for impairment using a quantitative assessment, we compare the fair value of each reporting unit to its carrying value. We determine the fair value using an income approach. Under the income approach, we calculate the fair value of a reporting unit based on the present value of estimated future cash flows using growth rates and discount rates that are consistent with current market conditions in our industry. If the fair value of the reporting unit exceeds the carrying value of the net assets including goodwill assigned to that unit, goodwill is not impaired. If the carrying value of the reporting unit’s net assets including goodwill exceeds the fair value of the reporting unit, then we record an impairment charge based on that difference. In addition to the income approach, we calculate the fair value of our reporting units under a market approach. The market approach measures the fair value of a reporting unit through analysis of financial multiples of comparable businesses. Consideration is given to the financial conditions and operating performance of the reporting unit being valued relative to those publicly-traded companies operating in the same or similar lines of business. Significant judgment is required when applying the market approach as there is a range of financial multiples of comparable businesses. Based on our interim goodwill impairment test, we determined that the fair values of the reporting units were in excess of the carrying values; therefore, we did not record any goodwill impairment. The excess of the fair values over the carrying values of our reporting units ranged from 2% - 206%. The significant assumptions used to estimate fair values included sales growth, profitability, and related cash flows, along with cash flows associated with taxes and capital spending. The discount rate used to estimate fair value was risk adjusted in consideration of the economic conditions in effect at the time of the impairment test. We also considered assumptions that market participants may use. In our quantitative assessments, the discount rates ranged from 10.0% to 17.0%, the 2020 to 2029 compounded annual revenue growth rates ranged from 2.0% to 8.3%, and the revenue growth rates beyond 2029 ranged from 2.0% to 3.0%. By their nature, these assumptions involve risks and uncertainties. Furthermore, uncertainties associated with current market conditions increase the inherent risk associated with using an income approach to estimate fair values. While we have adjusted our key assumptions to reflect the current economic conditions, we have also assumed that economic conditions will improve beyond 2020. If current conditions persist and actual results are different from our estimates or assumptions, we may have to recognize an impairment charge that could be material.

Restructuring and Related Activities [Abstract]
Severance, Restructuring, and Acquisition Integration Activities	Severance, Restructuring, and Acquisition Integration Activities Cost Reduction Program: 2019 During the fourth quarter of 2019, we began a cost reduction program to improve performance and enhance margins by streamlining the organizational structure and investing in technology to drive productivity. We recognized $3.5 million and $3.0 million of severance and other restructuring costs for this program during the three and six months ended June 28, 2020, respectively. The cost reduction program is expected to deliver an estimated $60.0 million reduction in selling, general, and administrative expenses on an annual basis, of which $40.0 million is expected to be realized in 2020, with the full benefit materializing in 2021. We expect to incur incremental costs of approximately $22.0 million for this program. SPC, Opterna and FutureLink Integration Program: 2019 In 2019, we began a restructuring program to integrate SPC, Opterna and FutureLink with our existing businesses. The restructuring and integration activities were focused on achieving desired cost savings by consolidating existing and acquired facilities and other support functions. We recognized $0.9 million and $3.1 million of severance and other restructuring costs for this program during the three and six months ended June 28, 2020, respectively. We recognized $2.5 million of severance and other restructuring costs for this program during the three and six months ended June 30, 2019. These costs were incurred by the Enterprise Solutions segment. We expect to incur incremental costs of approximately $1.5 million for this program. The following table summarizes the costs by segment of the programs described above as well as other immaterial programs and acquisition integration activities during the three and six months ended June 28, 2020 and June 30, 2019: Severance Other Total Costs Three Months Ended June 28, 2020 (In thousands) Enterprise Solutions $ 1,467 $ 956 $ 2,423 Industrial Solutions 1,773 276 2,049 Total $ 3,240 $ 1,232 $ 4,472 Three Months Ended June 30, 2019 Enterprise Solutions $ — $ 2,519 $ 2,519 Industrial Solutions — — — Total $ — $ 2,519 $ 2,519 Six Months Ended June 28, 2020 Enterprise Solutions $ 835 $ 4,138 $ 4,973 Industrial Solutions 818 2,300 3,118 Total $ 1,653 $ 6,438 $ 8,091 Six Months Ended June 30, 2019 Enterprise Solutions $ — $ 2,519 $ 2,519 Industrial Solutions — — — Total $ — $ 2,519 $ 2,519 The other restructuring and integration costs primarily consisted of equipment transfer, costs to consolidate operating and support facilities, retention bonuses, relocation, travel, legal, and other costs.

Income Taxes	Income Taxes For the three and six months ended June 28, 2020, we recognized income tax expense of $0.4 million and $2.6 million, respectively, representing an effective tax rate of 11.2% and 12.5%, respectively. The effective tax rates were impacted by income tax benefits for certain foreign tax credits of $0.1 million and $1.2 million in the three and six months ended June 28, 2020, respectively. In March 2020, the Coronavirus Relief and Economic Security Act (CARES Act) was signed into law in the United States. We are still analyzing the provisions of the CARES Act to determine if there will be any impact to our income tax provision for the year. For the three and six months ended June 30, 2019, we recognized income tax expense of $4.0 million and $10.1 million, respectively, representing an effective tax rate of 8.7% and 12.7%, respectively. The effective tax rates were impacted by an income tax benefit of $6.4 million as a result of changes in our estimated valuation allowance requirement related to foreign tax credits due to the restructuring of certain foreign operations. These effective rates are also reflective of the impact of more favorable statutory tax rates applied to the earnings of these foreign operations due to the restructuring efforts.

Equity [Abstract]
Preferred Stock	Preferred StockIn 2016, we issued 5.2 million depositary shares, each of which represented 1/100th interest in a share of 6.75% Series B Mandatory Convertible Preferred Stock (the Preferred Stock), for an offering price of $100 per depositary share. We received approximately $501 million of net proceeds from this offering, which were used for general corporate purposes. On July 15, 2019, all outstanding Preferred Stock was automatically converted into shares of Belden common stock at the conversion rate of 132.50, resulting in the issuance of approximately 6.9 million shares of Belden common stock. Upon conversion, the Preferred Stock was automatically extinguished and discharged, is no longer deemed outstanding for all purposes, and delisted from trading on the New York Stock Exchange. During the three and six months ended June 30, 2019, dividends on the Preferred Stock were $8.7 million and $17.5 million, respectively.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	6 Months Ended
	Jun. 28, 2020
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Condensed Consolidated Financial Statements include Belden Inc. and all of its subsidiaries (the Company, us, we, or our). We eliminate all significant affiliate accounts and transactions in consolidation. The accompanying Condensed Consolidated Financial Statements presented as of any date other than December 31, 2019: • Are prepared from the books and records without audit, and • Are prepared in accordance with the instructions for Form 10-Q and do not include all of the information required by accounting principles generally accepted in the United States for complete statements, but • Include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the financial statements.
Business Description	Business Description We are a global supplier of specialty networking solutions built around two global business platforms - Enterprise Solutions and Industrial Solutions. Our comprehensive portfolio of solutions enables customers to transmit and secure data, sound, and video for mission critical applications across complex enterprise and industrial environments.
Reporting Periods	Reporting PeriodsOur fiscal year and fiscal fourth quarter both end on December 31. Our fiscal first quarter ends on the Sunday falling closest to 91 days after December 31, which was March 29, 2020, the 89th day of our fiscal year 2020. Our fiscal second and third quarters each have 91 days. The six months ended June 28, 2020 and June 30, 2019 included 180 and 181 days, respectively.
Fair Value Measurement	Fair Value Measurement Accounting guidance for fair value measurements specifies a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources or reflect our own assumptions of market participant valuation. The hierarchy is broken down into three levels based on the reliability of the inputs as follows: • Level 1 – Quoted prices in active markets that are unadjusted and accessible at the measurement date for identical, unrestricted assets or liabilities; • Level 2 – Quoted prices for identical assets and liabilities in markets that are not active, quoted prices for similar assets and liabilities in active markets, or financial instruments for which significant inputs are observable, either directly or indirectly; and • Level 3 – Prices or valuations that require inputs that are both significant to the fair value measurement and unobservable. As of and during the three and six months ended June 28, 2020 and June 30, 2019, we utilized Level 1 inputs to determine the fair value of cash equivalents, and we utilized Level 2 and Level 3 inputs to determine the fair value of net assets acquired in business combinations (see Note 3) and for impairment testing (see Notes 4 and 10). We did not have any transfers between Level 1 and Level 2 fair value measurements during the six months ended June 28, 2020 and June 30, 2019.
Cash and Cash Equivalents	Cash and Cash Equivalents We classify cash on hand and deposits in banks, including commercial paper, money market accounts, and other investments with an original maturity of three months or less, that we hold from time to time, as cash and cash equivalents. We periodically have cash equivalents consisting of short-term money market funds and other investments. As of June 28, 2020, we did not have any such cash equivalents on hand. The primary objective of our investment activities is to preserve our capital for the purpose of funding operations. We do not enter into investments for trading or speculative purposes. During the six months ended June 28, 2020, we paid the sellers of Snell Advanced Media (SAM) the full earnout consideration of $31.4 million in cash as per the purchase agreement. SAM was acquired on February 8, 2018 and is included in the Grass Valley disposal group. Due to the initial uncertainties arising from the COVID-19 pandemic and out of an abundance of caution, we borrowed $190.0 million and subsequently repaid $100.0 million under our Revolving Credit Agreement during the second quarter. See Note 12.
Contingent Liabilities	Contingent Liabilities We have established liabilities for environmental and legal contingencies that are probable of occurrence and reasonably estimable, the amounts of which are currently not material. We accrue environmental remediation costs based on estimates of known environmental remediation exposures developed in consultation with our environmental consultants and legal counsel. We are, from time to time, subject to routine litigation incidental to our business. These lawsuits primarily involve claims for damages arising out of the use of our products, allegations of patent or trademark infringement, and litigation and administrative proceedings involving employment matters and commercial disputes. Based on facts currently available, we believe the disposition of the claims that are pending or asserted will not have a materially adverse effect on our financial position, results of operations, or cash flow. As of June 28, 2020, we were party to standby letters of credit, bank guaranties, and surety bonds totaling $7.7 million, $4.1 million, and $3.3 million, respectively.
Revenue Recognition	Revenue Recognition We recognize revenue consistent with the principles as outlined in the following five step model: (1) identify the contract with the customer, (2) identify the performance obligations in the contract, (3) determine the transaction price, (4) allocate the transaction price to the performance obligations in the contract, and (5) recognize revenue when (or as) each performance obligation is satisfied. See Note 2.
Subsequent Events	Subsequent EventsWe evaluated subsequent events after the balance sheet date through the financial statement issuance date for appropriate accounting and disclosure.
Noncontrolling Interest	Noncontrolling Interest We have a 51% ownership percentage in a joint venture with Shanghai Hi-Tech Control System Co, Ltd (Hite). The purpose of the joint venture is to develop and provide certain Industrial Solutions products and integrated solutions to customers in China. Belden and Hite are committed to fund $1.53 million and $1.47 million, respectively, to the joint venture in the future. The joint venture is determined to not have sufficient equity at risk; therefore, it is considered a variable interest entity. We have determined that Belden is the primary beneficiary of the joint venture, due to both our ownership percentage and our control over the activities of the joint venture that most significantly impact its economic performance based on the terms of the joint venture agreement with Hite. Because Belden is the primary beneficiary of the joint venture, we have consolidated the joint venture in our financial statements. The results of the joint venture attributable to Hite’s ownership are presented as net income (loss) attributable to noncontrolling interest in the Condensed Consolidated Statements of Operations. The joint venture is not material to our Condensed Consolidated financial statements as of or for the periods ended June 28, 2020 and June 30, 2019.
