Accounting Policies [Abstract]
Mobile Mini, Organization and Description of Business	(1) Mobile Mini, Organization and Description of Business Mobile Mini, Inc., a Delaware corporation, is a leading provider of portable storage and specialty containment solutions. In these notes, the terms “Mobile Mini,” the “Company,” “we,” “us,” and “our” refer to Mobile Mini, Inc. In November 2014, we entered into a Stock Purchase Agreement to acquire Gulf Tanks Holdings (“GTH”), Inc., the parent company of Houston, Texas-based Evergreen Tank Solutions (“ETS”). The transaction, referred to as the “ETS Acquisition,” closed on December 10, 2014. See additional information regarding the acquisition in Note 3. On May 15, 2015, we closed a transaction to sell our wood mobile offices within our North American portable storage segment for a cash price of $92.0 million, less associated assumed liabilities. See additional information regarding the divestiture in Note 4. At December 31, 2016, we have a fleet of portable storage and office units operating throughout the U.S., Canada and the U.K. serving a diversified customer base, including large and small retailers, construction companies, medical centers, schools, utilities, distributors, the military, hotels, restaurants, entertainment complexes and households. These customers use our products for a wide variety of applications, including the storage of retail and manufacturing inventory, construction materials and equipment, documents and records and other goods. We also have a fleet of specialty containment products, concentrated in the Gulf Coast region of the U.S., including liquid and solid containment units, serving a specialty sector in the industry. Specialty products are leased primarily to chemical, refinery, oil and natural gas drilling, mining and environmental service customers. Basis of Presentation and Consolidation The consolidated financial statements include the accounts of Mobile Mini and our wholly owned subsidiaries. We do not have any subsidiaries in which we do not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and the notes to those statements. Actual results could differ from those estimates. Significant estimates affect the calculation of depreciation and amortization, the calculation of the allowance for doubtful accounts, the analysis of goodwill and long-lived assets for potential impairment and certain accrued liabilities.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	(2) Summary of Significant Accounting Policies Cash Equivalents We consider all highly liquid instruments with insignificant interest rate risk and with maturities of three months or less at purchase to be cash equivalents. Receivables and Allowance for Doubtful Accounts Receivables are stated net of an allowance for doubtful accounts. We estimate the amount of customer receivables that are uncollectible and record an estimated provision for bad debts through a charge to operations. The provision is based on historical collection experience and evaluation of past-due accounts. Specific accounts are written off against the allowance when management determines the account is uncollectible. We require a security deposit on most leased office units to cover the cost of damages or unpaid balances, if any. Our provision for doubtful accounts was less than 1.5% of total revenues in the years ended December 31, 2016, 2015 and 2014. The information presented in the table below reflects the activity in the allowance for doubtful accounts during the periods presented. For the Years Ended December 31, 2016 2015 2014 (In thousands) Balance at beginning of year $ 2,162 $ 1,636 $ 1,377 Provision charged to expense 6,162 3,705 2,777 Write-offs and other (3,438 ) (3,179 ) (2,518 ) Balance at end of year $ 4,886 $ 2,162 $ 1,636 Concentration of Credit Risk Financial instruments which potentially expose us to concentrations of credit risk consist primarily of receivables. Concentration of credit risk with respect to receivables is limited due to our large number of customers spread over a broad geographic area in many industry sectors. No single customer accounts for more than 15% of our receivables at December 31, 2016 and 2015. Receivables related to sold units are generally secured by the product sold to the customer. We typically have the right to repossess rented portable storage units, including any customer goods contained in the unit, following non-payment of rent. Inventories Inventories are valued at the lower of cost (principally on a standard cost basis which approximates the first-in, first-out method) or net realizable value. Raw materials and supplies principally consist of raw steel, wood, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes, and to a lesser extent, parts used for internal maintenance and ancillary items held for sale in our specialty containment segment. Work-in-process primarily represents partially assembled units pre-sold or for use as fleet. Finished portable storage units primarily represent purchased or assembled containers held in inventory until the container is either sold as is, remanufactured and sold, or remanufactured and deployed as rental fleet. Inventories at December 31 consisted of the following: 2016 2015 (In thousands) Raw materials and supplies $ 12,908 $ 13,436 Work-in-process 31 189 Finished units 2,473 1,971 Inventories $ 15,412 $ 15,596 Rental fleet Rental fleet is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred. We periodically review depreciable lives and residual values against various factors, including the results of our lenders’ independent appraisal of our rental fleet, practices of our competitors in comparable industries and profit margins achieved on sales of depreciated units. Property, Plant and Equipment Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is recorded using the straight-line method over the assets’ estimated useful lives. Our depreciation expense related to property, plant and equipment for 2016, 2015 and 2014 was $25.1 million, $20.2 million and $15.1 million, respectively. Normal repairs and maintenance to property, plant and equipment are expensed as incurred. When property or equipment is retired or sold, the net book value of the asset, reduced by any proceeds, is charged to gain or loss on the disposal of property, plant and equipment and is included in rental, selling and general expenses in the Consolidated Statements of Income. Property, plant and equipment at December 31 consisted of the following: Residual Value as Percentage of Original Cost Useful Life in Years 2016 2015 (In thousands) Land $ 3,789 $ 4,045 Vehicles and machinery 0 - 55% 5 - 30 131,584 118,185 Buildings and improvements (1) 0 - 25 3 - 30 22,750 21,549 Furniture, office and computer equipment 0 3 - 10 63,969 47,063 Property, plant and equipment 222,092 190,842 Accumulated depreciation and amortization (72,895 ) (59,155 ) Property, plant and equipment, net $ 149,197 $ 131,687 (1) Improvements made to leased properties are depreciated over the lesser of the estimated useful life or the remaining term of the respective lease Capitalized Software Development Costs We capitalize qualifying computer software costs incurred during the application development stage for internally developed software. Additionally, we capitalize qualifying costs incurred for upgrades and enhancements to existing software that result in additional functionality. Costs related to preliminary project planning activities, post-implementation activities, maintenance and minor modifications are expensed as incurred. Internal-use software is amortized on a straight line basis over its estimated useful life. Capitalized software development costs are included in property, plant and equipment. As of December 31, 2016 and 2015, we had $35.0 million and $23.5 million, respectively, of capitalized software, net of accumulated depreciation, included in property, plant and equipment. Of the $35.0 million of capitalized software, $31.7 million related to the development of our new ERP system, which was executed in stages in 2016. Deferred Financing Costs Deferred financing costs are included in other assets in the Consolidated Balance Sheet and consist of the costs of obtaining long-term financing. These costs are amortized over the term of the related debt, using the straight-line method, which approximates the effective interest method. Amortization expense for deferred financing costs was approximately $2.0 million, $3.1 million and $2.8 million in 2016, 2015 and 2014, respectively. As discussed in Note 6, we entered into the Credit Agreement in December 2015, resulting in the capitalization of $4.6 million in third-party and lender fees. In addition, in 2015, we wrote off $0.9 million of deferred financing costs related to the prior credit agreement. As of December 31, 2016, $5.6 million of the total $10.4 million unamortized deferred financing costs, related to the Credit Agreement. Also as discussed in Note 6, in 2016 we issued $250.0 million aggregate principal amount of the 2024 Notes and capitalized $5.2 million of deferred financing costs. Proceeds from the issuance of the 2024 Notes were used in part to redeem $200.0 million in aggregate principal amount of the 2020 Notes. As a result of the redemption of the 2020 Notes during the current-year period, we wrote off $2.3 million of previously deferred costs that had not yet been amortized. The annual amortization of deferred financing costs is expected to be as follows (in thousands): 2017 2,059 2018 2,059 2019 2,059 2020 2,000 2021 638 Thereafter 1,596 Total $ 10,411 Goodwill For acquired businesses, we record assets acquired and liabilities assumed at their estimated fair values on the respective acquisition dates. Based on these values, the excess purchase prices over the fair value of the net assets acquired is recorded as goodwill. Of the $703.6 million total goodwill at December 31, 2016, $468.5 million related to the North America portable storage segment, $53.9 million related to the U.K. portable storage segment and $181.2 million related to the specialty containment segment. Goodwill impairment testing requires judgment, including: the identification of the reporting units; determination of the fair value of each reporting unit; the assignment of assets, liabilities and goodwill to each reporting unit; estimates and assumptions regarding future cash flows and discount rates; and an assumption regarding the form of the transaction in which the reporting unit would be acquired by a market participant. Management assesses potential impairment of goodwill on an annual basis at December 31, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Some factors management considers important which could indicate an impairment review include the following: • significant under-performance relative to historical, expected or projected future operating results; • significant changes in the manner of our use of the acquired assets or the strategy for the overall business; • market capitalization relative to net book value; and • significant negative industry or general economic trends. Management may choose to assess qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether or not to perform the two-step goodwill impairment test. When we review goodwill for impairment utilizing a two-step process, the first step of the impairment test requires a comparison of the fair value of each of our reporting unit’s net assets to the respective carrying value of net assets. If the carrying value of a reporting unit’s net assets is less than its fair value, no indication of impairment exists and a second step is not performed. If the carrying amount of a reporting unit’s net assets is higher than its fair value, there is an indication that an impairment may exist and a second step must be performed. If the second step is necessary, management is required to determine the implied fair value of the goodwill and compare it to the carrying value of the goodwill. The fair value of the reporting units would be assigned to the respective assets and liabilities of each reporting unit as if the reporting units had been acquired in separate and individual business combinations and the fair value of the reporting units was the price paid to acquire the reporting units. The excess of the fair value of the reporting units over the amounts assigned to their respective assets and liabilities is the implied fair value of goodwill. If the carrying amount of the reporting unit’s goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the difference. In assessing the fair value of the reporting units, management considers both the market approach and the income approach. Under the market approach, the fair value of the reporting unit is based on quoted market prices of companies comparable to the reporting unit being valued. Under the income approach, the fair value of the reporting unit is based on the present value of estimated cash flows. The income approach is dependent on a number of significant management assumptions, including estimated future revenue growth rates, gross margins on sales, operating margins, capital expenditures, tax payments and discount rates. Each approach is given equal weight in arriving at the fair value of the reporting unit. As of December 31, 2016, management assessed qualitative factors and determined it is more likely than not each of the reporting unit’s assigned goodwill had estimated fair values greater than the respective reporting unit’s individual net asset carrying values; therefore, the two step impairment test was not performed. In connection with our goodwill impairment test that was conducted as of December 31, 2015, we bypassed the qualitative assessment for each of our reporting units and proceeded directly to the first step of the goodwill impairment test. Our goodwill impairment testing as of this date indicated that both of our portable storage reporting units and our specialty containment reporting unit had estimated fair values which substantially exceeded their respective carrying amounts. The second step of the impairment test was not required for any of the reporting units. The following table shows the activity and balances related to goodwill from January 1, 2015 to December 31, 2016: (In thousands) Balance at January 1, 2015 (1) $ 705,608 Acquisitions 5,371 Adjustments (717 ) Foreign currency (2) (3,875 ) Balance at December 31, 2015 (1) 706,387 Acquisitions 6,449 Adjustments 1,071 Foreign currency (2) (10,349 ) Balance at December 31, 2016 (1) $ 703,558 (1) Includes accumulated amortization of $2.0 million and accumulated impairment of $12.5 million. (2) Represents foreign currency translation adjustments related to the U.K. portable storage reporting unit. Intangibles Intangible assets are amortized over the estimated useful life of the asset utilizing a method which reflects the estimated pattern in which the economic benefits will be consumed. Customer relationships are amortized based on the estimated attrition rates of the underlying customer base, other intangibles are amortized using the straight-line method. The following table reflects balances related to intangible assets for the years ended December 31: 2016 2015 Estimated Useful Life Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount (In thousands) Customer relationships 15 - 20 $ 92,515 $ (28,729 ) $ 63,786 $ 92,304 $ (24,875 ) $ 67,429 Trade names/trademarks 5 - 10 5,892 (2,364 ) 3,528 6,025 (1,684 ) 4,341 Non-compete agreements 5 1,886 (813 ) 1,073 1,839 (433 ) 1,406 Other 20 59 (26 ) 33 60 (24 ) 36 Total $ 100,352 $ (31,932 ) $ 68,420 $ 100,228 $ (27,016 ) $ 73,212 Amortization expense for amortizable intangibles was approximately $6.4 million, $6.0 million and $1.6 million in 2016, 2015 and 2014, respectively. See information regarding intangibles acquired in conjunction with company acquisitions in Note 3. Based on the carrying value at December 31, 2016, future amortization of intangible assets is expected to be as follows for the years ended December 31 (in thousands): 2017 $ 6,481 2018 6,398 2019 6,295 2020 5,138 2021 4,903 Thereafter 39,205 Total $ 68,420 Impairment of Long-Lived Assets (Other than Goodwill) Our rental fleet, property, plant and equipment, and finite-lived intangibles are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may be impaired. (See potential impairment indicators under “Goodwill” above). If this review indicates the carrying value of these assets will not be recoverable, as measured based on estimated undiscounted cash flows over their remaining life, the carrying amount would be adjusted to fair value. The cash flow estimates contain management’s best estimates using appropriate and customary assumptions and projections at the time of evaluation. During the first quarter of 2015, we entered into discussions regarding the possible sale of our wood mobile offices within our North American portable storage segment. The discussions indicated that the fleet might be sold at an amount below carrying value and we conducted a review for impairment for these long-lived assets as of March 31, 2015. Based on this review, an impairment loss was recorded in the quarter ended March 31, 2015. The total impairment of the wood mobile offices was $64.6 million during 2015. See additional discussion regarding the impairment and the divestiture of the wood mobile offices in Note 4. There were no indicators of further impairment at December 31, 2016 or at December 31, 2015. Purchase Accounting We account for acquisitions under the acquisition method. Under the acquisition method of accounting, we record assets acquired and liabilities assumed at their estimated fair market value on the date of acquisition. Goodwill is measured as the excess of the fair value of the consideration transferred over the fair value of the identifiable net assets. Estimated fair values of acquired assets and liabilities is provisional and could change as additional information is received. We finalize valuations as soon as practicable, but not later than one-year from the acquisition date. Any subsequent changes to purchase price allocations results in a corresponding adjustment to goodwill. The determination of the fair value of intangible assets requires the use of significant judgment with regard to (i) the fair value; and (ii) whether such intangibles are amortizable or non-amortizable and, if amortizable, the period and the method by which the intangible asset will be amortized. We estimate the fair value of acquisition-related intangible assets principally based on projections of cash flows that will arise from identifiable intangible assets of acquired businesses. The projected cash flows are discounted to determine the present value of the assets at the dates of acquisition. Revenue Recognition Rental revenue is generated from the direct rental of our fleet to our customers, including ancillary revenue such as fleet delivery and pickup. We enter into contracts with our customers to rent equipment based on a monthly rate for our portable storage fleet and a daily, weekly or monthly rate for our specialty containment fleet. Revenues from renting are recognized ratably over the rental period. The rental continues until cancelled by the customer or the Company. Customers may utilize our equipment delivery and pick-up services in conjunction with the rental of equipment, but it is not required. Revenue pursuant to the pick up or delivery of a rented unit is recognized in rental revenue upon completion of the service. When customers are billed in advance, we defer recognition of revenue and record unearned rental revenue at the end of the period. If equipment is returned prior to the end of the contractually obligated period, the excess, if any, between the amount the customer is contractually required to pay, over the cumulative amount of revenue recognized to date, is recognized as incremental revenue upon return. Sales revenue is primarily generated by the sale of new and used units, and to a lesser extent, parts and supplies sold to specialty containment customers. We recognize revenues from sales of units upon delivery when the risk of loss passes, the price is fixed and determinable and collectability is reasonably assured. We sell our units pursuant to sales contracts stating the fixed sales price. Cost of Sales Cost of sales in our consolidated statements of income includes the costs for units we sell, and to a lesser extent the costs of parts and supplies sold to specialty containment customers. Similar costs associated with units that we rent are capitalized in the balance sheet under “Rental fleet”. Advertising Costs Advertising expense was $3.9 million, $4.1 million and $5.2 million in 2016, 2015 and 2014, respectively. The balance of prepaid advertising costs, which are never amortized more than twelve months, was less than $0.1 million at both December 31, 2016 and 2015. Income Taxes In preparing our consolidated financial statements, we recognize income taxes in each of the jurisdictions in which we operate. For each jurisdiction, we estimate the actual amount of taxes currently payable or receivable as well as deferred tax assets and liabilities attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which it is more likely than not that the related benefits will not be realized. In determining the amount of the valuation allowance, we consider estimated future taxable income as well as feasible tax planning strategies in each jurisdiction. If we determine that we will not realize all or a portion of our deferred tax assets, we will increase our valuation allowance with a charge to income tax expense. Conversely, if we determine that we will ultimately be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced with a credit to income tax expense. We record uncertain tax positions using a two-step process, whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within the interest expense line and other expense line, respectively, in the accompanying Consolidated Statement of Income. Accrued interest and penalties are included within the related liability lines in the Consolidated Balance Sheet. Earnings per Share Basic earnings per share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated under the treasury stock method. Potential common shares included restricted common stock, which is subject to risk of forfeiture, incremental shares of common stock issuable upon the exercise of stock options and vesting of restricted stock awards. The following table is a reconciliation of net income and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted EPS for the years ended December 31: For the Years Ended December 31, 2016 2015 2014 (In thousands, except per share data) Numerator: Net income $ 47,248 $ 5,574 $ 44,386 Denominator: Weighted average shares outstanding - basic 44,145 44,953 46,026 Dilutive effect of share-based awards 245 507 699 Weighted average shares outstanding - diluted 44,390 45,460 46,725 Earnings per share: Basic $ 1.07 $ 0.12 $ 0.96 Diluted 1.06 0.12 0.95 Basic weighted average number of common shares outstanding does not include restricted stock awards that had not vested of 0.2 million, 0.2 million and 0.3 million shares in 2016, 2015 and 2014, respectively. The following table represents the number of stock options and restricted stock awards that were issued or outstanding but excluded in calculating diluted EPS because their effect would have been anti-dilutive for the years ended December 31: For the Years Ended December 31, 2016 2015 2014 (In thousands) Stock options 2,076 1,135 751 Restricted stock awards 5 1 — Total 2,081 1,136 751 Fair Value Measurements Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement determined by assumptions that market participants would use in pricing an asset or liability. We categorize each of our fair value measurements in one of the following three levels based on the lowest level of input that is significant to the fair value measurement: Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2 — Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and Level 3 — Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts of cash, cash equivalents, receivables, accounts payable and accrued liabilities approximate fair values based on their short-term nature. The fair values of our revolving credit facility and capital leases are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to us for bank loans with similar terms and average maturities, the fair value of our revolving credit facility debt and capital leases, which are measured using Level 2 inputs, at December 31, 2016 and 2015 approximated their respective book values. During 2016, we redeemed all $200.0 million aggregate principal amount of our outstanding 7.875% senior notes due December 1, 2020 (“2020 Notes”), and issued $250.0 million aggregate principal amount of 5.875% senior notes due July 1, 2024 (“2024 Notes”). See more information in Note 6. The fair value of our 2020 Notes and 2024 Notes (together, the “Senior Notes”) for the periods presented below is based on their latest sales price at the end of each period obtained from a third-party institution and is Level 2 in the fair value hierarchy as there is not an active market for these Senior Notes. The Senior Notes are presented on the balance sheet net of debt issuance costs. The gross carrying value and the fair value of the Senior Notes are as follows: 2016 2015 (In thousands) Carrying value $ 250,000 $ 200,000 Fair value 258,750 207,000 At December 31, 2016 and 2015, we did not have any financial instruments required to be recorded at fair value on a recurring basis. Derivatives In the normal course of business, our operations are exposed to fluctuations in interest rates. We have in the past, and may again in the future, address a portion of these risks through a controlled program of risk management that includes the use of derivative financial instruments. The objective of controlling these risks is to limit the impact of fluctuations in interest rates on earnings. At December 31, 2016 and 2015, we did not have any derivative financial instruments. Share-Based Compensation We calculate the fair value of stock options using the Black-Scholes-Merton option pricing valuation model, which incorporates various assumptions including volatility, expected life and risk-free interest rates. The fair value of restricted stock awards is estimated as the closing price of our common stock on the date of grant. Compensation related to service-based awards are recognized on a straight-line basis over the vesting period, which is generally three to five years. Compensation expense related to performance-based awards is recognized over the implicit service period of the award based on management’s estimate of the probability of the performance criteria being satisfied, adjusted at each balance sheet date. Expense related to performance-based awards that have multiple vesting dates, is recognized using the accelerated attribution approach, whereby each vesting tranche is treated as a separate award for purposes of determining the implicit service period. Share based compensation expense is reduced for forfeitures which are estimated at the time of grant based on historical experience, and revised in subsequent periods if actual forfeitures differ from estimates. Foreign Currency Translation and Transactions For our non-U.S. operations, the local currency is the functional currency. All assets and liabilities are translated into U.S. dollars at period-end exchange rates and all income statement amounts are translated at the average exchange rate for each month within the year. Impact of Recently Issued Accounting Standards Share-Based Compensation. In March 2016, the Financial Accounting Standards Board (“FASB”) issued a standard intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. This standard is effective for annual and interim periods beginning after December 15, 2016. We will implement this standard in the first quarter of 2017. This standard eliminates the requirement that excess tax benefits be realized before companies can recognize them. As a result, utilizing the modified retrospective method, we expect to record a cumulative-effect adjustment for previously unrecognized excess tax benefits of $18.5 million in the opening balance sheet for 2017, with an offsetting increase to retained earnings (deficit). In addition, the standard allows us to make a policy election to either continue to reduce share-based compensation expense for forfeitures in future periods, or to recognize forfeitures as they occur. We have chosen to record forfeitures as they occur and will record immaterial adjustments to reflect a cumulative-effect adjustment for the difference between the fair value estimate of awards historically expected to be forfeited and the fair value estimate of awards actually forfeited. This standard also requires all excess tax benefits and tax deficiencies associated with the exercise of stock options and vesting of restricted stock to be recorded as income tax expense or benefit. Increases and decreases in the aggregate intrinsic value (or negative value) of such activity could introduce volatility in our effective tax rate. We do not expect the remaining provisions of the new guidance to have a material effect on our consolidated financial statements. Leases . In February 2016, FASB issued a standard on lease accounting requiring a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. This standard is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted and the standard requires the use of a modified retrospective transition method. While we are continuing to evaluate all potential impacts of the standard, we do not believe the accounting for our contractual rental revenue will be materially affected by the adoption of this standard. We anticipate the lessee accounting for operating leases under the standard will have a material effect on our statement of financial position. Simplifying the Presentation of Debt Issuance Costs. In April 2015, FASB issued accounting guidance on the presentation of debt issuance costs in the balance sheet. This standard requires that certain 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. The recognition and measurement guidance for debt issuance costs are not affected by this guidance. We adopted this guidance during 2016. As a result, unamortized debt issuance costs of $4.8 million and $2.4 million as of December 31, 2016 and December 31, 2015, respectively, have been deducted from the carrying amount of the Senior Notes in our balance sheet. Unamortized debt issuance costs related to our revolving credit facility are included in other assets. Revenue from Contracts with Customers. In May 2014, FASB issued an accounting standard on revenue from contracts with customers. The standard provides a single model for revenue arising from contracts with customers and supersedes current revenue recognition guidance. The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services and is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted for the annual and interim periods beginning after December 15, 2016, but not prior to that time. The revenue recognition standard permits the use of either the retrospective or cumulative effect transition method. While we are continuing to assess all potential impacts of the standard, we currently believe the majority of our revenue, as relates to contractual rental revenue, is excluded from the scope of this standard, and the accounting for the remaining revenue streams will not be materially affected. Accordingly, we do not anticipate that the adoption of this standard will have a material impact on our consolidated financial statements. We expect to utilize the modified retrospective adoption and recognize the cumulative effect of initially applying the standard, if any, as an adjustment to the opening b

Business Combinations [Abstract]
Acquisitions	(3) Acquisitions 2016 Acquisitions During the year ended December 31, 2016, we completed three acquisitions of portable storage businesses. One acquisition expanded our business in Dallas, Texas. The other two were in the United Kingdom. The accompanying consolidated financial statements include the operations of the acquired businesses from the dates of acquisition. The aggregate purchase price for the assets acquired were recorded based on their estimated fair values at the date of the acquisitions. We have not disclosed the pro-forma impact of the acquisitions on operations as they were immaterial to our financial position or results of operations in the aggregate. The components of the purchase price and net assets acquired during the year ended December 31, 2016 are as follows (in thousands): Net Assets Acquired: Cash $ 1,562 Rental fleet 10,054 Property, plant and equipment 285 Intangible assets: Customer relationships 1,616 Non-compete agreements 50 Goodwill 6,449 Other assets 1,236 Other liabilities (3,125 ) Total $ 18,127 Total, less cash acquired $ 16,565 2015 Acquisitions During the year ended December 31, 2015, we completed two acquisitions of portable storage businesses. These acquisitions expanded our existing operations in the Glasgow, Scotland market, and further strengthened our positions in Knoxville and Chattanooga, Tennessee. The accompanying consolidated financial statements include the operations of the acquired businesses from the dates of acquisition. The aggregate purchase price for the assets acquired were recorded based on their estimated fair values at the date of the acquisitions. We have not disclosed the pro-forma impact of the acquisitions on operations as they were immaterial to our financial position or results of operations in the aggregate. The components of the purchase price and net assets acquired during the year ended December 31, 2015 (as adjusted in 2016) are as follows (in thousands): Net Assets Acquired: Rental fleet $ 11,057 Property, plant and equipment 157 Intangible assets: Customer relationships 759 Non-compete agreements 74 Goodwill 6,443 Other assets 316 Other liabilities (281 ) Total $ 18,525 2014 Acquisitions On December 10, 2014, we acquired all of the outstanding equity interests of GTH, the parent company of ETS, referred to as the ETS Acquisition. As a result of the ETS Acquisition, included in our consolidated statements of income for the years ended December 31, 2016, 2015 and 2014 is $98.1 million, $107.3 million and $6.4 million, respectively, of specialty containment revenues and $2.3 million, $11.1 million and $1.1 million, respectively, of income from continuing operations before income tax provision. Direct expenses related to the ETS Acquisition were $2.5 million in the twelve months ended December 31, 2015 and $5.0 million in the fourth quarter of 2014. Also in 2014, we completed eight other acquisitions of portable storage businesses through both asset purchase and stock purchase agreements. The purchased assets and assumed liabilities were recorded at their estimated fair value at the date of acquisition. Five of these acquisitions expanded our existing operations in North Dakota, North Carolina, Texas, Tennessee, Florida and South Carolina markets. The other three acquisitions created new locations in the Danbury, Connecticut, Fort Wayne, Indiana and Buffalo, New York metropolitan areas. The accompanying consolidated financial statements include the operations of the acquired businesses from the date of acquisition. The aggregate purchase price for the assets acquired and the liabilities assumed were recorded based on their estimated fair values at the date of each acquisition. Valuations were performed based on available information at the time of acquisition. Estimated fair values of acquired assets and liabilities have changed immaterially as additional information was received. The components of the purchase price and net assets acquired for 2014 acquisitions are as follows: 2014 ETS Acquisition Other Acquisitions Total (In thousands) Purchase Price, net of cash acquired: Cash $ 410,345 $ 23,299 $ 433,644 Cash acquired (2,698 ) — (2,698 ) Total $ 407,647 $ 23,299 $ 430,946 Net Assets Acquired: Rental fleet $ 120,755 $ 12,697 $ 133,452 Property, plant and equipment 14,655 338 14,993 Intangible assets (1): Customer relationships 69,200 1,350 70,550 Trade names/trademarks 5,200 — 5,200 Non-compete agreements 1,500 204 1,704 Goodwill (2) 181,239 8,856 190,095 Deferred tax asset, net 4,696 — 4,696 Other assets (3) 25,332 538 25,870 Other liabilities (14,930 ) (684 ) (15,614 ) Total $ 407,647 $ 23,299 $ 430,946 (1) The following table reflects the estimated fair values and useful lives of intangible assets related to the ETS Acquisition identified based on our preliminary purchase accounting assessments: Estimated Life (Years) Customer relationships 15 - 20 Trade names/trademarks 5 - 10 Non-compete agreements 5 Customer relationships acquired in conjunction with the ETS Acquisition were evaluated separately for the wholly owned subsidiary Water Movers, Inc. (“Water Movers”). With input from an independent third party with extensive expertise and experience in this area, we determined lives for the two customer groups based upon historical and expected customer attrition rates, resulting in an expected useful life of 15 years for the Water Movers customer relationships, which were valued at $14.9 million, and an expected useful life of 20 years for the remaining ETS customer relationships, which were valued at $54.3 million. During our assessment, we evaluated annual historical sales data from 2009 through December 2014 for Water Movers, and 2008 through December 2014 for the remaining ETS customers. (2) All of the goodwill related to the ETS Acquisition was assigned to our specialty containment segment. The goodwill arising from the acquisition consists largely of ETS' going-concern value, the value of ETS’ assembled workforce, new customer relationships expected to arise from the acquisition, and operational synergies and economies of scale that we expect to realize from the acquisition. Goodwill from other acquisitions related to the North America portable storage segment. (3) Included in other assets for the ETS Acquisition are accounts receivable with contractual amounts totaling $24.3 million. We estimated that $0.6 million will be uncollectible, and valued acquired accounts receivable at $23.7 million. Supplemental Pro Forma Information The unaudited pro forma financial information is presented for informational purposes only and is not indicative, and should not be relied on as being indicative, of the results of operations that would have been achieved if the acquisition had actually taken place at the beginning of each of the periods presented. The pro forma financial information reflects only the ETS Acquisition, as the remaining acquisitions would not have a material effect on reported results of operations. The following table summarizes our unaudited consolidated statements of income as if the ETS Acquisition occurred on January 1, 2013: Year Ended December 31, 2014 (In thousands) Revenues: Mobile Mini's historic revenues $ 445,474 ETS' historic revenues (1) 101,603 Pro forma revenues $ 547,077 Net income: Mobile Mini's historic net income $ 44,386 ETS' historic net loss from continuing operations (25,862 ) Pro forma adjustments (2) 22,601 Pro forma net income $ 41,125 Average diluted weighted shares outstanding 46,725 Pro forma diluted earnings per share from continuing operations $ 0.88 (1) ETS historic information for the year ended December 31, 2014 consists of revenues and net loss prior to the acquisition date of December 10, 2014.

Impairment and Divestiture of N

Impairment and Divestiture of North American Wood Mobile Offices	12 Months Ended
	Dec. 31, 2016
Text Block [Abstract]
Impairment and Divestiture of North American Wood Mobile Offices	(4) Impairment and Divestiture of North American Wood Mobile Offices Our business strategy is to invest in high return, low maintenance, long-lived assets. Wood mobile offices require more maintenance and upkeep than Mobile Mini’s steel containers and steel ground level offices, resulting in lower margins as compared to our other portable storage products and our specialty containment products. During March 2015, we entered into discussions regarding the possible sale of our wood mobile offices within our North American portable storage segment. The discussions indicated that the fleet might be sold at an amount below carrying value. Based upon the events described above, we conducted a review for impairment for these particular long-lived assets as of March 31, 2015. The review included assumptions of cash flows considering the likelihood of possible outcomes that existed as of the date of the review, including assigning probabilities to these outcomes. Management estimated fair market value for the wood mobile offices based upon purchase price discussions. Based on this review, management determined that the assets were impaired as of March 31, 2015 and an impairment loss was recognized. On April 16, 2015, we entered into a definitive agreement to sell our wood mobile offices within the North American portable storage segment for a cash price of $92.0 million, less associated deferred revenue and customer deposits of $6.8 million.

Leases [Abstract]
Rental Fleet	(5) Rental Fleet Depreciation expense related to our rental fleet for 2016, 2015 and 2014 was $32.3 million, $34.1 million and $22.7 million, respectively. At December 31, 2016 and 2015, all rental fleet units were pledged as collateral under the Credit Agreement. Appraisals on our rental fleet are required by our lenders on a regular basis. The appraisal typically reports no difference in the value of the unit due to the age or length of time it has been in our fleet. Based in part upon our lender’s third-party appraiser who evaluated our fleet as of September 30, 2015, management estimates that the net orderly liquidation appraisal value as of December 31, 2016 was approximately $1.1 billion. Our net book value for this fleet as of December 31, 2016 was $950.1 million. Rental fleet at December 31 consisted of the following: Residual Value as Percentage of Original Cost (1) Useful Life in Years 2016 2015 (In thousands) Portable Storage: Steel storage containers 55% 30 $ 625,094 $ 612,782 Steel ground level offices 55% 30 347,574 346,233 Other 4,430 7,052 Total 977,098 966,067 Accumulated depreciation (151,238 ) (142,338 ) Total portable storage fleet, net $ 825,860 $ 823,729 Specialty Containment: Steel tanks 25 $ 61,955 $ 55,467 Roll-off boxes 15 - 20 28,743 25,161 Stainless steel tank trailers 25 29,150 28,160 Vacuum boxes 20 11,512 9,852 De-watering boxes 20 5,429 5,383 Pumps and filtration equipment 7 13,690 13,964 Other 6,150 6,843 Total 156,629 144,830 Accumulated depreciation (32,424 ) (17,236 ) Total specialty containment fleet, net $ 124,205 $ 127,594 Total rental fleet, net $ 950,065 $ 951,323 (1) Specialty containment fleet has been assigned zero residual value.

Debt Disclosure [Abstract]
Debt	(6) Debt Lines of Credit On December 14, 2015, we entered into the Credit Agreement with Deutsche Bank AG New York Branch, as administrative agent, and other lenders party thereto. The Credit Agreement provides for a five-year, $1.0 billion first lien senior secured revolving credit facility maturing on or before the earlier of (i) December 14, 2020 and (ii) the date that is 90 days prior to the final maturity date of the Senior Notes, if such Senior Notes remain outstanding on such date. The Credit Agreement also provides for the issuance of irrevocable standby letters of credit by U.S.-based lenders in amounts totaling up to $50.0 million, by U.K.-based lenders in amounts totaling up to $20.0 million, and by Canadian-based lenders in amounts totaling up to $20.0 million. The obligations of Mobile Mini and its subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of our assets. Amounts borrowed under the Credit Agreement and repaid or prepaid during the term may be reborrowed. Outstanding amounts under the Credit Agreement bear interest at our option at either: (i) the London interbank offered rate (“LIBOR”) plus an applicable margin (“LIBOR Loans”), or (ii) the prime rate plus an applicable margin (“Base Rate Loans”). The applicable margin for each type of loan is based on an availability-based pricing grid and ranges from 1.25% to 1.75% for LIBOR Loans and 0.25% to 0.75% for Base Rate Loans at each measurement date. As of December 31, 2016, the applicable margins are 1.50% for LIBOR Loans and 0.50% for Base Rate Loans. Availability of borrowings under the Credit Agreement is subject to a borrowing base calculation based upon a valuation of the Company’s eligible accounts receivable, eligible container fleet (including containers held for sale, work-in-process and raw materials) and machinery and equipment, each multiplied by an applicable advance rate or limit. The rental fleet is appraised at least once annually by a third-party appraisal firm and up to 90% of the net orderly liquidation value, as defined in the Credit Agreement, is included in the borrowing base to determine how much the Company may borrow under the Credit Agreement. The Credit Agreement provides for U.K. borrowings, which are, at the Company’s option, denominated in either Pounds Sterling or Euros, by its U.K. subsidiary based upon a U.K. borrowing base; Canadian borrowings, which are denominated in Canadian dollars, by its Canadian subsidiary based upon a Canadian borrowing base; and U.S. borrowings, which are denominated in U.S. dollars, by the Company based upon a U.S. borrowing base along with any Canadian assets not included in the Canadian subsidiary. The Credit Agreement also contains customary negative covenants, including covenants that restrict the Company’s ability to, among other things: (i) allow certain liens to attach to the Company’s or its subsidiaries’ assets, (ii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, or prepay certain indebtedness, (iii) incur additional indebtedness or engage in certain other types of financing transactions, and (iv) make acquisitions or other investments. In addition, we must comply with a minimum fixed charge coverage ratio of 1.00 to 1.00 as of the last day of each quarter, upon the minimum availability amount under the Credit Agreement falling below the greater of (y) $90 million and (z) 10% of the lesser of the then total revolving loan commitment and aggregate borrowing base. As of December 31, 2016, we were in compliance with the minimum borrowing availability threshold set forth in the Credit Agreement and, therefore, are not subject to any financial maintenance covenants. The weighted average interest rate under the lines of credit was approximately 2.1% in 2016 and 2.2% in 2015. The average outstanding balance was approximately $652.0 million and $670.4 million during 2016 and 2015, respectively. At December 31, 2016, the Company had approximately $641.2 million of borrowings outstanding and $354.3 million of additional borrowing availability under the Credit Agreement, based upon borrowing base calculations as of such date. Senior Notes On May 9, 2016, we issued $250.0 million aggregate principal amount of the 2024 Notes at an initial offering price of 100% of their face value. The net proceeds from the sale of the 2024 Notes were used to (i) redeem all $200.0 million aggregate principal amount of our outstanding 2020 Notes at a redemption price of 103.938% of the principal amount thereof plus accrued and unpaid interest to, but not including, the redemption date of June 8, 2016, (ii) repay a portion of the indebtedness outstanding under our asset-based revolving credit facility, and (iii) pay fees and expenses related to the offering of the 2024 Notes. As a result of the redemption of the 2020 Notes during the current-year period, we recognized $9.2 million in debt extinguishment expense, consisting of $7.9 million in debt redemption premiums and $1.3 million in contractually required interest above the amount payable prior to the redemption. Additionally, we wrote off $2.3 million of previously deferred costs associated with the 2020 Notes that had not yet been amortized. The 2024 Notes bear interest at a rate of 5.875% per year, accruing from May 9, 2016, have an eight-year term and mature on July 1, 2024. Interest on the 2024 Notes is payable semiannually in arrears on January 1 and July 1, beginning on January 1, 2017. The 2024 Notes are senior unsecured obligations of the Company and are unconditionally guaranteed on a senior unsecured basis by certain of our existing and future domestic subsidiaries. Obligations Under Capital Leases At December 31, 2016 and 2015, obligations under capital leases for certain real property, transportation, technology and office related equipment were $50.7 million and $38.3 million, respectively. Certain of the lease agreements provide us with a purchase option at the end of the lease term. The leases have been capitalized using interest rates primarily ranging from approximately 1.7% to 13.0% and are secured by the property and equipment under lease. Assets recorded under capital lease obligations totaled approximately $62.6 million as of December 31, 2016 and $44.5 million as of December 31, 2015. Related accumulated amortization totaled approximately $16.0 million as of December 31, 2016 and $7.6 million as of December 31, 2015. The assets acquired under capital leases and related accumulated amortization are included in property, plant and equipment, net, in the Consolidated Balance Sheets. The related amortization is included in depreciation and amortization expense in the Consolidated Statements of Income.

The 2015 effective tax rate was further affected by the losses in North America driven by asset impairment and restructuring expenses. The changes in the U.K. income tax rate resulted in a $0.9 million benefit and a $1.4 million benefit during the years ended December 31, 2016 and December 31, 2015, respectively. Excluding the North America asset impairment and the $1.4 million cumulative effect on prior-year deferred liabilities of the U.K. rate change, our tax rate for the year ended December 31, 2015 was 33.4%. The components of the net deferred tax liability at December 31 are approximately as follows: 2016 2015 (In thousands) Deferred tax assets: Net operating loss carryforwards $ 71,126 $ 90,540 Deferred revenue and expenses 11,050 10,755 Accrued compensation and other benefits 2,465 3,666 Allowance for doubtful accounts 2,026 1,041 Equity compensation 10,937 8,888 Capital leases 18,984 — Other 513 3,125 Total deferred tax assets 117,101 118,015 Valuation allowance (1,126 ) (1,126 ) Net deferred tax assets 115,975 116,889 Deferred tax liabilities Fixed assets (309,010 ) (297,575 ) Intangibles and goodwill (46,585 ) (36,704 ) Other (1,070 ) (2,211 ) Total deferred tax liabilities (356,665 ) (336,490 ) Net deferred tax liabilities $ (240,690 ) $ (219,601 ) A net deferred tax liability of approximately $18.5 million and $17.1 million related to our U.K. operations has been combined with the net deferred tax liabilities of our U.S. operations in the Consolidated Balance Sheets at December 31, 2016 and 2015, respectively. At December 31, 2016, we had U.S. federal net operating loss carryforwards on our federal tax return of approximately $236.6 million, which expire if unused from 2028 to 2034. At December 31, 2016, we had net operating loss carryforwards on the various states’ tax returns in which we operate totaling $123.6 million, which expire if unused from 2017 to 2035. Management evaluates the ability to realize our deferred tax assets on a quarterly basis and adjusts the amount of our valuation allowance if necessary. Over the past three years, we have generated $149.2 million of federal taxable income. Management currently believes that adequate future taxable income will be generated through future operations, or through available tax planning strategies to recover the unreserved portion of these deferred tax assets. For income tax purposes, deductible compensation related to share-based awards is based on the value of the award when realized, which may be different than the compensation expense recognized by us in our financial statements, which is based on the award value on the date of grant. The difference between the value of the award upon grant, and the value of the award when ultimately realized, creates either additional tax benefits or a tax shortfall. Tax benefits resulting from tax deductions in excess of the compensation cost recognized for share-based awards are recognized as increases to additional paid in capital and as financing cash flows, only if an incremental income tax benefit would be realized after considering all other tax attributes presently available to us. We have not recognized excess tax benefits in 2016, 2015 or 2014, because we have not paid U.S. federal income taxes in those years. Tax shortfalls, which occur when the tax deduction for share-based awards is less than the compensation cost recognized, are recorded as a reduction to additional paid in capital to the extent that, cumulatively, the shortfalls do not exceed the cumulative excess tax benefits recognized (including excess tax benefits not yet recognized in additional paid in capital). Should cumulative tax shortfalls exceed cumulative excess tax benefits, the difference would be reflected as additional tax expense in our financial statements. At December 31, 2016 and 2015, our net operating losses carrying forward for tax return purposes include $18.5 million and $17.7 million, respectively, of excess tax benefits from employee stock awards. See Note 2 for a discussion of the impact of recently issued accounting standards on excess tax benefits. A deferred U.S. tax liability has not been provided on the undistributed earnings of certain foreign subsidiaries because it is our intent to permanently reinvest such earnings. Undistributed earnings of foreign subsidiaries, which have been or are intended to be permanently invested, aggregated approximately $62.4 million and $47.2 million as of December 31, 2016 and 2015, respectively. The estimated unrecognized deferred tax liability associated with these temporary differences was approximately $11.5 million as of December 31, 2016. As a result of stock ownership changes during the years presented, it is possible that we have undergone a change in ownership for federal income tax purposes, which can limit the amount of net operating loss currently available as a deduction. We have determined that even if such an ownership change has occurred, it would not impair the realization of the deferred tax asset resulting from the federal net operating loss carryover. We paid income and franchise taxes of approximately $1.8 million in 2016, $4.9 million in 2015 and $1.1 million in 2014. These amounts are lower than the recorded expense in the years due to net operating loss carryforwards and general business credit utilization. We are subject to taxation in the U.S. federal jurisdiction, as well as various U.S. state and foreign jurisdictions. We have identified our U.S. federal tax return as our “major” tax jurisdiction. As of December 31, 2016, we are no longer subject to examination by U.S. federal tax authorities for years prior to 2013, to examination for any U.S. state taxing authority prior to 2011, or to examination for any foreign jurisdictions prior to 2012. All subsequent periods remain open to examination. Uncertain tax positions are recognized and measured using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation process, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. As of December 31, 2016, we had approximately $5.9 million of gross unrecognized tax benefits, of which, none would affect our effective tax rate if recognized. A reconciliation of the beginning and ending balance of unrecognized tax benefits is as follows: 2016 (In thousands) Beginning balance $ — Additions based on tax positions related to the current year — Additions for tax positions of prior years 5,874 Ending balance $ 5,874 Of the amount of unrecognized tax benefits outstanding at December 31, 2016, all of the amount is expected to reverse within the next twelve month. Our policy for recording interest and penalties associated with uncertain tax positions is to record such items as a component of income before taxes. Penalties and associated interest costs, if any, are recorded in rental, selling and general expenses in our Consolidated Statements of Income.

These leases began in 2013, prior to the ETS Acquisition, and expire in 2023. Rental payments under these leases are currently approximately $18,000 per month. Any future renewals of these leases will be approved by the Board as related party transactions. It is our intention not to enter into any additional related person transactions.

Share-Based Compensation

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Share-Based Compensation	(9) Share-Based Compensation We have historically awarded stock options and restricted stock awards for employees and non-employee directors as a means of attracting and retaining quality personnel and to align employee performance with stockholder value. Stock option plans are approved by our stockholders and administered by the compensation committee of the Board. The current plan allows for a variety of equity programs designed to provide flexibility in implementing equity and cash awards, including incentive stock options, nonqualified stock options, restricted stock awards, restricted stock units, stock appreciation rights, performance stock, performance units and other stock-based awards. Participants may be granted any one of the equity awards or any combination. We do not award stock options with an exercise price below the market price of the underlying securities on the date of award. As of December 31, 2016, 2.0 million shares are available for future grants. Generally stock options have contractual terms of ten years. Service-based awards. We grant share-based compensation awards that vest over time subject to the employee rendering service over the vesting period. The majority of the service–based awards vest in equal annual installments over a period of three to five years. The expense for service-based awards is expensed ratably over the full service period of the grant. Performance-based awards . All stock options granted in 2016 vest contingently over a three-year period upon the achievement of certain performance criteria related to the operating performance of the Company. Participants may earn from 50% to 200% of the target options awarded assuming at least minimum targets are achieved, and depending on actual results. If minimum targets are not achieved no options are vested. Options which are not vested in any given year are forfeited, but the subsequent years are not affected. For certain awards granted prior to 2016, there is also a cumulative performance objective. Expense related to performance-based awards that have multiple vesting dates, is recognized using the accelerated attribution approach, whereby each vesting tranche is treated as a separate award for purposes of determining the implicit service period. The accelerated attribution approach results in a higher expense during the earlier years of vesting. Non-employee director awards . Each non-employee director serving on the Board receives an automatic award of shares of Mobile Mini’s common stock annually. These awards vest 100% when granted. For the years ended December 31, 2016, 2015 and 2014, $0.8 million, $0.8 million and $0.9 million, respectively, of expense was recognized related to these grants. Share-based compensation expense . The following table summarizes our share-based compensation for the years ended December 31: For the Years Ended December 31, 2016 2015 2014 (In thousands) Share-based compensation expense included in: Rental, selling and general expenses $ 7,220 $ 12,277 $ 14,490 Restructuring expenses 179 1,550 581 Total share-based compensation $ 7,399 $ 13,827 $ 15,071 As of December 31, 2016, total unrecognized compensation cost related to stock option awards was approximately $2.7 million and the related weighted-average period over which it is expected to be recognized is approximately 1.1 years. As of December 31, 2016, the unrecognized compensation cost related to restricted stock awards was approximately $5.0 million, which is expected to be recognized over a weighted-average period of approximately 2.3 years. Stock options . The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes-Merton option pricing model which requires the input of assumptions. We estimate the risk-free interest rate based on the U.S. Treasury security rate in effect at the time of the grant. The expected life of the options, volatility and dividend rates are estimated based on our historical data. The following are the key assumptions used for the period noted: 2016 2015 2014 Risk-free interest rate 1.1% - 1.5% 1.3% - 1.7% 1.5% - 1.7% Expected life of the options (years) 5.0 5.0 5.0 Expected stock price volatility 35.3% - 35.3% - 35.4% - Expected dividend rate 2.2% - 3.1% 1.8% - 2.1% 1.5% - 1.8% The following table summarizes stock option activity for the years ended December 31 (share amounts in thousands): 2016 2015 2014 Number of Shares Weighted Average Exercise Price Number of Shares Weighted Average Exercise Price Number of Shares Weighted Average Exercise Price Options outstanding, beginning of year 2,870 $ 33.40 2,649 $ 32.33 2,519 $ 29.80 Granted 594 26.54 381 42.80 365 46.83 Canceled/Expired (155 ) 36.07 (98 ) 44.60 (71 ) 40.63 Exercised (17 ) 28.50 (62 ) 27.56 (164 ) 22.18 Options outstanding, end of year 3,292 32.06 2,870 33.40 2,649 32.33 Options exercisable, end of year 2,508 1,643 854 29.32 The stock options granted in 2016 are performance-based and are shown in the table at the target award. The actual amount of shares that ultimately vest depends on achievement of performance criteria. As of December 31, 2016, approximately 0.5 million performance-based stock options remain unvested. Shares contingently vesting based upon 2016 performance criteria did not achieve the minimum vesting target criteria, resulting in the forfeiture of 0.2 million shares in January 2017. The shares are included as outstanding in the tables above and below. A summary of stock options outstanding as of December 31, 2016, is as follows: Number of Shares Weighted Average Exercise Price Weighted Average Remaining Contractual Terms Aggregate Intrinsic Value (In thousands) (In years) (In thousands) Outstanding 3,292 $ 32.06 6.83 $ 5,985 Vested and expected to vest 3,228 32.11 6.78 5,786 Exercisable 2,508 31.98 6.25 3,950 The aggregate intrinsic value of options exercised during the period ended December 31, 2016, 2015 and 2014 was $0.1 million, $0.8 million and $2.9 million, respectively. The weighted average fair value of stock options granted was $6.64, $8.43 and $10.46 for the years ended December 31, 2016, 2015 and 2014, respectively. Restricted Stock Awards . The fair value of restricted stock awards is estimated as the closing price of our common stock on the date of grant. A summary of restricted stock activity is as follows (share amounts in thousands): Shares Weighted Average Grant Date Fair Value Restricted stock awards at January 1, 2014 542 $ 20.65 Awarded 143 39.77 Released (240 ) 20.93 Forfeited (102 ) 22.09 Restricted stock awards at December 31, 2014 343 27.99 Awarded 107 37.17 Released (169 ) 28.22 Forfeited (39 ) 25.07 Restricted stock awards at December 31, 2015 242 31.70 Awarded 172 27.39 Released (130 ) 29.75 Forfeited (41 ) 28.36 Restricted stock awards at December 31, 2016 243 30.27 The total fair value of restricted stock awards that vested in 2016, 2015 and 2014 were $3.8 million, $4.8 million and $5.0 million, respectively.

Benefit Plans	(10) Benefit Plans In the U.S. we sponsor 401(k) retirement plans designed to provide tax-deferred retirement benefits to employees in accordance with the provisions of Section 401(k) of the Internal Revenue Code. We also sponsor defined contribution programs in the U.K., and have a Registered Retirement Savings Plan regulated by Canadian law. Under the U.S. and Canadian plans we match a percentage of the participants’ contributions up to a specified amount. Under the U.K. plan, we contribute a percentage of each participant’s annual salary to the plan and, depending on the plan, employees may also be required to contribute a percentage of their annual salary into the plan. In the U.S. plans Company matches vest over a period of two to five years, while Company matches for U.K. and Canadian employees are immediately vested. Company contributions to all these benefit plans totaled approximately $0.9 million, $1.1 million and $0.7 million in 2016, 2015 and 2014, respectively. In each of the three years ending December 31, 2016, 2015 and 2014, we incurred approximately $32,000, $51,000 and $34,000, respectively, for administrative costs for these programs.

Rent expense under these agreements was approximately $22.3 million, $22.7 million and $21.3 million for the years ended December 31, 2016, 2015 and 2014, respectively. As of December 31, 2016, contractual commitments associated with lease obligations are as follows: Operating Lease Commitments Restructuring Related Lease Commitments Sub-lease Income Total (In thousands) 2017 $ 17,270 $ 432 $ (207 ) $ 17,495 2018 12,539 289 — 12,828 2019 9,931 24 — 9,955 2020 7,848 — — 7,848 2021 5,131 — — 5,131 Thereafter 14,017 — — 14,017 Total $ 66,736 $ 745 $ (207 ) $ 67,274 Future minimum lease payments under restructured non-cancelable operating leases as of December 31, 2016, are included in accrued liabilities in the Consolidated Balance Sheet. See Note 13 for a further discussion on restructuring related commitments. Insurance Reserves We maintain insurance coverage for our operations and employees with appropriate aggregate, per occurrence and deductible limits as we reasonably determine is necessary or prudent considering current operations and historical experience. The majority of these coverages have large deductible programs which allow for potential improved cash flow benefits based on our loss control efforts, while guarantying a maximum premium liability. Our employee group health insurance program is a self-insured program with individual and aggregate stop loss limits. The insurance provider is responsible for funding all claims in excess of the calculated monthly maximum liability. This calculation is based on a variety of factors including the number of employees enrolled in the plan. Actual results may vary from estimates based on our actual experience at the end of the plan policy periods based on the carrier’s loss predictions and our historical claims data. We expense the deductible portion of the individual claims. However, we generally do not know the full amount of our exposure to a deductible in connection with any particular claim during the fiscal period in which the claim is incurred and for which we must make an accrual for the deductible expense. We make these accruals based on a combination of the claims development experience of our staff and our insurance companies, and, at year end, the accrual is reviewed and adjusted, in part, based on an independent actuarial review of historical loss data and using certain actuarial assumptions followed in the insurance industry. A high degree of judgment is required in developing these estimates of amounts to be accrued, as well as in connection with the underlying assumptions. In addition, our assumptions will change as our loss experience is developed. All of these factors have the potential for significantly impacting the amounts previously reserved in respect of anticipated deductible expenses and we may be required in the future to increase or decrease amounts previously accrued. Our worker’s compensation, auto and general liability insurance are purchased under large deductible programs. Our current per incident deductibles are: worker’s compensation $250,000, auto $500,000 and general liability $50,000. Under our various insurance programs, we have collective reserves recorded in accrued liabilities of $4.2 million and $3.8 million at December 31, 2016 and 2015, respectively. In connection with the issuance of our insurance policies, we have provided our various insurance carriers approximately $4.5 million in letters of credit as of December 31, 2016. General Litigation We are a party to various claims and litigation in the normal course of business. Our current estimated range of liability related to various claims and pending litigation is based on claims for which our management can determine that it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. Because of the uncertainties related to both the probability of incurred and possible range of loss on pending claims and litigation, management must use considerable judgment in making reasonable determination of the liability that could result from an unfavorable outcome. As additional information becomes available, we will assess the potential liability related to our pending litigation and revise our estimates. Such revisions in our estimates of the potential liability could materially impact our results of operation. We do not anticipate the resolution of such matters known at this time will have a material adverse effect on our business or consolidated financial position.

Equity [Abstract]
Stockholders' Equity	(12) Stockholders’ Equity Dividends During the twelve months ended December 31, 2016 we paid cash dividends of $0.82 per share for a total of $36.4 million. Each future quarterly dividend payment is subject to review and approval by the Board. In addition, our Credit Agreement contains restrictions on the declaration and payment of dividends. Treasury stock On November 6, 2013, the Board approved a share repurchase program authorizing up to $125.0 million of our outstanding shares of common stock to be repurchased. On April 17, 2015, the Board authorized up to an additional $50.0 million of our outstanding shares of common stock to be repurchased, for a total of $175.0 million under the share repurchase program. The shares may be repurchased from time to time in the open market or in privately negotiated transactions. The share repurchases are subject to prevailing market conditions and other considerations. The share repurchase program does not have an expiration date and may be suspended or terminated at any time by the Board. All shares repurchased are held in treasury. During the twelve months ended December 31, 2016, we purchased approximately 0.4 million shares of our common stock at a cost of $10.8 million under the authorized share repurchase program, and approximately $78.2 million is available for repurchase as of December 31, 2016. In addition, we withheld approximately 16,000 shares of stock from employees, for an approximate value of $0.5 million, upon vesting of share awards to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program. During the twelve months ended December 31, 2015, we purchased approximately 1.7 million shares of our common stock at a cost of $61.0 million under the authorized share repurchase program. In addition, we withheld approximately 21,000 shares of stock from employees, for an approximate value of $0.8 million, upon vesting of share awards to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program. During the twelve months ended December 31, 2014, we purchased approximately 0.6 million shares of our common stock at a cost of $25.0 million under the authorized share repurchase program. In addition, we withheld approximately 25,000 shares of stock from employees, for an approximate value of $1.0 million, upon vesting of share awards to satisfy minimum tax withholding obligations. These shares were not acquired pursuant to the share repurchase program.

Restructuring And Related Activities [Abstract]
Restructuring Costs	(13) Restructuring Costs We have undergone restructuring actions to align our business operations. The restructuring costs in 2016 resulted primarily to the continuation of projects initiated in prior years. Integration of ETS into the existing Mobile Mini infrastructure For the twelve months ended December 31, 2016 and 2015, we recognized $2.0 million and $19.7 million, respectively, in expenses related to activities associated with the integration of ETS into the existing Mobile Mini infrastructure. The integration has included such activities as: • Combining portable storage and specialty containment locations in markets where both lines of business are present, • Expanding either line of business to new geographies where we maintain a presence in the other, • Eliminating duplicative or redundant positions at both the corporate level and in operations, and • Determining the appropriate processes, including the alignment of sales leadership with operational leadership, and eliminating infrastructure that does not function optimally in the new environment. As part of the integration process, in 2015, as the Company was finalizing locations in Southern California for combined portable storage and specialty containment equipment operations, we determined that certain of our current locations in Southern California would either not be optimal or available to accommodate efficient operations and provide desired proximity to our combined customer base. To accommodate the needs of the planned combined operations, the Company is leasing new property, exiting certain properties and has abandoned approximately 5,000 units of the portable storage fleet in Southern California at the legacy yards. This abandonment resulted in $13.7 million of restructuring expense in the fourth quarter of 2015, representing the write-down of this fleet to zero value. Other costs related to performance of the integration include $0.5 million and $4.6 million for severance and benefits, for the years ended December 31, 2016 and 2015, respectively. Included in the severance and benefits is $0.2 million and $1.6 million of share-based compensation, for each year respectively. In 2015, we also recognized $1.4 million for the write-off and loss on sale of property, plant and equipment, related to the integration. Other restructuring We recognized $3.3 million and $0.8 million during the twelve months ended December 31, 2016 and 2015, respectively, related to the abandonment of yards, or portions of yards, as well as related fleet and other costs due to our move away from the wood mobile office business. The 2014 restructuring costs resulted from the restructuring of U.K. locations, including the sale of the Belfast, North Ireland location. In addition, the Company’s field management and sales force structures in North America were realigned in 2014 along with other organizational changes. The following table details accrued restructuring obligations (included in accrued liabilities in the Consolidated Balance Sheets) and related activity for the years ended December 31, 2016, 2015 and 2014: Fleet and Property, Plant and Equipment Abandonment Costs Severance and Benefits Lease Abandonment Costs Other Costs Total (In thousands) Accrued obligations as of January 1, 2014 $ — $ 613 $ 1,063 $ — $ 1,676 Restructuring expense 1,295 1,826 318 103 3,542 Settlement of obligations (1,295 ) (1,998 ) (705 ) (103 ) (4,101 ) Accrued obligations as of December 31, 2014 — 441 676 — 1,117 Restructuring expense 15,274 4,846 600 78 20,798 Settlement of obligations (15,274 ) (4,042 ) (781 ) (76 ) (20,173 ) Accrued obligations as of December 31, 2015 — 1,245 495 2 1,742 Restructuring expense 109 1,006 3,453 1,452 6,020 Settlement of obligations (109 ) (1,856 ) (3,580 ) (1,454 ) (6,999 ) Accrued obligations as of December 31, 2016 $ — $ 395 $ 368 $ — $ 763 The following amounts are included in restructuring expense for the years ended December 31: 2016 2015 2014 (In thousands) Fleet and property, plant and equipment abandonment costs $ 109 $ 15,274 $ 1,295 Severance and benefits 1,006 4,846 1,826 Lease abandonment costs 3,453 600 318 Other costs 1,452 78 103 Restructuring expenses $ 6,020 $ 20,798 $ 3,542

Segment Reporting

Segment Reporting [Abstract]
Segment Reporting	(14) Segment Reporting Prior to the ETS Acquisition, our operations were comprised of two reportable segments: North America and the U.K., both of which offer portable storage solutions. Discrete financial data on each of our products is not available and it would be impractical to collect and maintain financial data in such a manner. As a result of the ETS Acquisition, we established a new specialty containment reportable segment. ETS operations are included in our results of operations for all of 2016 and 2015, and the portion of 2014 subsequent to the acquisition date, which is less than one month. The results for each segment are reviewed discretely by our chief operating decision maker. We operate in the U.S., U.K. and Canada. All of our locations operate in their local currency and, although we are exposed to foreign exchange rate fluctuation in foreign markets where we rent and sell our products, we do not believe such exposure will have a significant impact on our results of operations. Revenues recognized by our U.S. locations were $424.4 million, $438.4 million and $353.2 million for the twelve months ended December 31, 2016, 2015 and 2014, respectively. The following tables set forth certain information regarding each of our reportable segments for the years ended December 31, 2016, 2015 and 2014: For the Year Ended December 31, 2016 Portable Storage North America United Kingdom Total Specialty Containment Consolidated (In thousands) Revenues: Rental $ 309,221 $ 77,924 $ 387,145 $ 92,938 $ 480,083 Sales 18,852 2,724 21,576 4,923 26,499 Other 1,530 310 1,840 200 2,040 Total revenues 329,603 80,958 410,561 98,061 508,622 Costs and expenses: Rental, selling and general expenses 197,440 48,096 245,536 63,758 309,294 Cost of sales 11,248 2,071 13,319 3,152 16,471 Restructuring expenses 5,419 — 5,419 601 6,020 Depreciation and amortization 28,722 6,787 35,509 28,225 63,734 Total costs and expenses 242,829 56,954 299,783 95,736 395,519 Income from operations $ 86,774 $ 24,004 $ 110,778 $ 2,325 $ 113,103 Interest expense, net of interest income $ 20,920 $ 536 $ 21,456 $ 11,268 $ 32,724 Income tax provision (benefit) 22,687 2,921 25,608 (3,958 ) 21,650 Capital expenditures for additions to rental fleet, excluding acquisitions 32,270 10,851 43,121 14,251 57,372 For the Year Ended December 31, 2015 Portable Storage North America United Kingdom Total Specialty Containment Consolidated (In thousands) Revenues: Rental $ 310,864 $ 84,227 $ 395,091 $ 99,624 $ 494,715 Sales 18,833 3,554 22,387 7,566 29,953 Other 5,697 340 6,037 72 6,109 Total revenues 335,394 88,121 423,515 107,262 530,777 Costs and expenses: Rental, selling and general expenses 210,323 53,423 263,746 62,506 326,252 Cost of sales 11,852 2,728 14,580 5,091 19,671 Restructuring expenses 17,790 — 17,790 3,008 20,798 Asset impairment charge and loss on divestiture, net 66,128 — 66,128 — 66,128 Depreciation and amortization 28,200 6,628 34,828 25,516 60,344 Total costs and expenses 334,293 62,779 397,072 96,121 493,193 Income from operations $ 1,101 $ 25,342 $ 26,443 $ 11,141 $ 37,584 Interest expense, net of interest income $ 24,249 $ 876 $ 25,125 $ 10,774 $ 35,899 Income tax (benefit) provision (8,639 ) 3,369 (5,270 ) 448 (4,822 ) Capital expenditures for additions to rental fleet, excluding acquisitions 28,532 22,154 50,686 24,046 74,732 For the Year Ended December 31, 2014 Portable Storage North America United Kingdom Total Specialty Containment Consolidated (In thousands) Revenues: Rental $ 323,236 $ 81,703 $ 404,939 $ 5,423 $ 410,362 Sales 26,834 4,588 31,422 163 31,585 Other 2,274 407 2,681 846 3,527 Total revenues 352,344 86,698 439,042 6,432 445,474 Costs and expenses: Rental, selling and general expenses 221,405 56,189 277,594 3,354 280,948 Cost of sales 18,251 3,587 21,838 106 21,944 Restructuring expenses 1,915 1,627 3,542 — 3,542 Asset impairment charge, net 433 124 557 — 557 Depreciation and amortization 30,670 6,790 37,460 1,874 39,334 Total costs and expenses 272,674 68,317 340,991 5,334 346,325 Income from operations $ 79,670 $ 18,381 $ 98,051 $ 1,098 $ 99,149 Interest expense, net of interest income $ 27,816 $ 905 $ 28,721 $ 8 $ 28,729 Income tax provision 21,580 4,042 25,622 411 26,033 Capital expenditures for additions to rental fleet, excluding acquisitions 10,620 11,711 22,331 4,948 27,279 Assets related to our reportable segments include the following: Portable Storage North America United Kingdom Total Specialty Containment Consolidated (In thousands) As of December 31, 2016: Goodwill $ 468,464 $ 53,878 $ 522,342 $ 181,216 $ 703,558 Intangibles, net 1,959 899 2,858 65,562 68,420 Rental fleet, net 688,477 137,383 825,860 124,205 950,065 As of December 31, 2015: Goodwill $ 463,616 $ 61,532 $ 525,148 $ 181,239 $ 706,387 Intangibles, net 2,021 403 2,424 70,788 73,212 Rental fleet, net 672,080 151,649 823,729 127,594 951,323 Included in the Consolidated Balance Sheet are assets in the U.S. of $1.6 billion as of both December 31, 2016 and 2015.

In management’s opinion, this unaudited consolidated quarterly selected information has been prepared on the same basis as the audited consolidated financial statements and includes all necessary adjustments, consisting only of normal recurring adjustments, which management considers necessary for a fair presentation when read in conjunction with the Consolidated Financial Statements and notes. We believe these comparisons of consolidated quarterly selected financial data are not necessarily indicative of future performance. Quarterly EPS may not total to the fiscal year EPS due to the weighted average number of shares outstanding at the end of each period reported and rounding.

Mobile Mini, Organization and Description of Business (Policies)	12 Months Ended
	Dec. 31, 2016
Accounting Policies [Abstract]
Basis of Presentation and Consolidation	Basis of Presentation and Consolidation The consolidated financial statements include the accounts of Mobile Mini and our wholly owned subsidiaries. We do not have any subsidiaries in which we do not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the accompanying consolidated financial statements and the notes to those statements. Actual results could differ from those estimates. Significant estimates affect the calculation of depreciation and amortization, the calculation of the allowance for doubtful accounts, the analysis of goodwill and long-lived assets for potential impairment and certain accrued liabilities.
Cash Equivalents	Cash Equivalents We consider all highly liquid instruments with insignificant interest rate risk and with maturities of three months or less at purchase to be cash equivalents.
Receivables and Allowance for Doubtful Accounts	Receivables and Allowance for Doubtful Accounts Receivables are stated net of an allowance for doubtful accounts. We estimate the amount of customer receivables that are uncollectible and record an estimated provision for bad debts through a charge to operations. The provision is based on historical collection experience and evaluation of past-due accounts. Specific accounts are written off against the allowance when management determines the account is uncollectible. We require a security deposit on most leased office units to cover the cost of damages or unpaid balances, if any. Our provision for doubtful accounts was less than 1.5% of total revenues in the years ended December 31, 2016, 2015 and 2014. The information presented in the table below reflects the activity in the allowance for doubtful accounts during the periods presented. For the Years Ended December 31, 2016 2015 2014 (In thousands) Balance at beginning of year $ 2,162 $ 1,636 $ 1,377 Provision charged to expense 6,162 3,705 2,777 Write-offs and other (3,438 ) (3,179 ) (2,518 ) Balance at end of year $ 4,886 $ 2,162 $ 1,636
Concentration of Credit Risk	Concentration of Credit Risk Financial instruments which potentially expose us to concentrations of credit risk consist primarily of receivables. Concentration of credit risk with respect to receivables is limited due to our large number of customers spread over a broad geographic area in many industry sectors. No single customer accounts for more than 15% of our receivables at December 31, 2016 and 2015. Receivables related to sold units are generally secured by the product sold to the customer. We typically have the right to repossess rented portable storage units, including any customer goods contained in the unit, following non-payment of rent.
Inventories	Inventories Inventories are valued at the lower of cost (principally on a standard cost basis which approximates the first-in, first-out method) or net realizable value. Raw materials and supplies principally consist of raw steel, wood, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes, and to a lesser extent, parts used for internal maintenance and ancillary items held for sale in our specialty containment segment. Work-in-process primarily represents partially assembled units pre-sold or for use as fleet. Finished portable storage units primarily represent purchased or assembled containers held in inventory until the container is either sold as is, remanufactured and sold, or remanufactured and deployed as rental fleet. Inventories at December 31 consisted of the following: 2016 2015 (In thousands) Raw materials and supplies $ 12,908 $ 13,436 Work-in-process 31 189 Finished units 2,473 1,971 Inventories $ 15,412 $ 15,596
Rental fleet	Rental fleet Rental fleet is capitalized at cost and depreciated over the estimated useful life of the unit using the straight-line method. Rental fleet is depreciated whether or not it is out on rent. Capitalized cost of rental fleet includes the price paid to acquire the unit and freight charges to the location when the unit is first placed in service, and when applicable, the cost of manufacturing or remanufacturing, which includes the cost of customizing units. Ordinary repair and maintenance costs are charged to operations as incurred. We periodically review depreciable lives and residual values against various factors, including the results of our lenders’ independent appraisal of our rental fleet, practices of our competitors in comparable industries and profit margins achieved on sales of depreciated units.
Property, Plant and Equipment	Property, Plant and Equipment Property, plant and equipment are stated at cost, net of accumulated depreciation and amortization. Depreciation is recorded using the straight-line method over the assets’ estimated useful lives. Our depreciation expense related to property, plant and equipment for 2016, 2015 and 2014 was $25.1 million, $20.2 million and $15.1 million, respectively. Normal repairs and maintenance to property, plant and equipment are expensed as incurred. When property or equipment is retired or sold, the net book value of the asset, reduced by any proceeds, is charged to gain or loss on the disposal of property, plant and equipment and is included in rental, selling and general expenses in the Consolidated Statements of Income. Property, plant and equipment at December 31 consisted of the following: Residual Value as Percentage of Original Cost Useful Life in Years 2016 2015 (In thousands) Land $ 3,789 $ 4,045 Vehicles and machinery 0 - 55% 5 - 30 131,584 118,185 Buildings and improvements (1) 0 - 25 3 - 30 22,750 21,549 Furniture, office and computer equipment 0 3 - 10 63,969 47,063 Property, plant and equipment 222,092 190,842 Accumulated depreciation and amortization (72,895 ) (59,155 ) Property, plant and equipment, net $ 149,197 $ 131,687 (1) Improvements made to leased properties are depreciated over the lesser of the estimated useful life or the remaining term of the respective lease
Capitalized Software Development Costs	Capitalized Software Development Costs We capitalize qualifying computer software costs incurred during the application development stage for internally developed software. Additionally, we capitalize qualifying costs incurred for upgrades and enhancements to existing software that result in additional functionality. Costs related to preliminary project planning activities, post-implementation activities, maintenance and minor modifications are expensed as incurred. Internal-use software is amortized on a straight line basis over its estimated useful life. Capitalized software development costs are included in property, plant and equipment. As of December 31, 2016 and 2015, we had $35.0 million and $23.5 million, respectively, of capitalized software, net of accumulated depreciation, included in property, plant and equipment. Of the $35.0 million of capitalized software, $31.7 million related to the development of our new ERP system, which was executed in stages in 2016.
Deferred Financing Costs	Deferred Financing Costs Deferred financing costs are included in other assets in the Consolidated Balance Sheet and consist of the costs of obtaining long-term financing. These costs are amortized over the term of the related debt, using the straight-line method, which approximates the effective interest method. Amortization expense for deferred financing costs was approximately $2.0 million, $3.1 million and $2.8 million in 2016, 2015 and 2014, respectively. As discussed in Note 6, we entered into the Credit Agreement in December 2015, resulting in the capitalization of $4.6 million in third-party and lender fees. In addition, in 2015, we wrote off $0.9 million of deferred financing costs related to the prior credit agreement. As of December 31, 2016, $5.6 million of the total $10.4 million unamortized deferred financing costs, related to the Credit Agreement. Also as discussed in Note 6, in 2016 we issued $250.0 million aggregate principal amount of the 2024 Notes and capitalized $5.2 million of deferred financing costs. Proceeds from the issuance of the 2024 Notes were used in part to redeem $200.0 million in aggregate principal amount of the 2020 Notes. As a result of the redemption of the 2020 Notes during the current-year period, we wrote off $2.3 million of previously deferred costs that had not yet been amortized. The annual amortization of deferred financing costs is expected to be as follows (in thousands): 2017 2,059 2018 2,059 2019 2,059 2020 2,000 2021 638 Thereafter 1,596 Total $ 10,411
Goodwill	Goodwill For acquired businesses, we record assets acquired and liabilities assumed at their estimated fair values on the respective acquisition dates. Based on these values, the excess purchase prices over the fair value of the net assets acquired is recorded as goodwill. Of the $703.6 million total goodwill at December 31, 2016, $468.5 million related to the North America portable storage segment, $53.9 million related to the U.K. portable storage segment and $181.2 million related to the specialty containment segment. Goodwill impairment testing requires judgment, including: the identification of the reporting units; determination of the fair value of each reporting unit; the assignment of assets, liabilities and goodwill to each reporting unit; estimates and assumptions regarding future cash flows and discount rates; and an assumption regarding the form of the transaction in which the reporting unit would be acquired by a market participant. Management assesses potential impairment of goodwill on an annual basis at December 31, or whenever events or changes in circumstances indicate that the carrying value may not be recoverable. Some factors management considers important which could indicate an impairment review include the following: • significant under-performance relative to historical, expected or projected future operating results; • significant changes in the manner of our use of the acquired assets or the strategy for the overall business; • market capitalization relative to net book value; and • significant negative industry or general economic trends. Management may choose to assess qualitative factors to determine if it is more-likely-than-not that goodwill might be impaired and whether or not to perform the two-step goodwill impairment test. When we review goodwill for impairment utilizing a two-step process, the first step of the impairment test requires a comparison of the fair value of each of our reporting unit’s net assets to the respective carrying value of net assets. If the carrying value of a reporting unit’s net assets is less than its fair value, no indication of impairment exists and a second step is not performed. If the carrying amount of a reporting unit’s net assets is higher than its fair value, there is an indication that an impairment may exist and a second step must be performed. If the second step is necessary, management is required to determine the implied fair value of the goodwill and compare it to the carrying value of the goodwill. The fair value of the reporting units would be assigned to the respective assets and liabilities of each reporting unit as if the reporting units had been acquired in separate and individual business combinations and the fair value of the reporting units was the price paid to acquire the reporting units. The excess of the fair value of the reporting units over the amounts assigned to their respective assets and liabilities is the implied fair value of goodwill. If the carrying amount of the reporting unit’s goodwill is greater than the implied fair value of its goodwill, an impairment loss must be recognized for the difference. In assessing the fair value of the reporting units, management considers both the market approach and the income approach. Under the market approach, the fair value of the reporting unit is based on quoted market prices of companies comparable to the reporting unit being valued. Under the income approach, the fair value of the reporting unit is based on the present value of estimated cash flows. The income approach is dependent on a number of significant management assumptions, including estimated future revenue growth rates, gross margins on sales, operating margins, capital expenditures, tax payments and discount rates. Each approach is given equal weight in arriving at the fair value of the reporting unit. As of December 31, 2016, management assessed qualitative factors and determined it is more likely than not each of the reporting unit’s assigned goodwill had estimated fair values greater than the respective reporting unit’s individual net asset carrying values; therefore, the two step impairment test was not performed. In connection with our goodwill impairment test that was conducted as of December 31, 2015, we bypassed the qualitative assessment for each of our reporting units and proceeded directly to the first step of the goodwill impairment test. Our goodwill impairment testing as of this date indicated that both of our portable storage reporting units and our specialty containment reporting unit had estimated fair values which substantially exceeded their respective carrying amounts. The second step of the impairment test was not required for any of the reporting units. The following table shows the activity and balances related to goodwill from January 1, 2015 to December 31, 2016: (In thousands) Balance at January 1, 2015 (1) $ 705,608 Acquisitions 5,371 Adjustments (717 ) Foreign currency (2) (3,875 ) Balance at December 31, 2015 (1) 706,387 Acquisitions 6,449 Adjustments 1,071 Foreign currency (2) (10,349 ) Balance at December 31, 2016 (1) $ 703,558 (1) Includes accumulated amortization of $2.0 million and accumulated impairment of $12.5 million. (2) Represents foreign currency translation adjustments related to the U.K. portable storage reporting unit.
Intangibles	Intangibles Intangible assets are amortized over the estimated useful life of the asset utilizing a method which reflects the estimated pattern in which the economic benefits will be consumed. Customer relationships are amortized based on the estimated attrition rates of the underlying customer base, other intangibles are amortized using the straight-line method. The following table reflects balances related to intangible assets for the years ended December 31: 2016 2015 Estimated Useful Life Gross Carrying Amount Accumulated Amortization Net Carrying Amount Gross Carrying Amount Accumulated Amortization Net Carrying Amount (In thousands) Customer relationships 15 - 20 $ 92,515 $ (28,729 ) $ 63,786 $ 92,304 $ (24,875 ) $ 67,429 Trade names/trademarks 5 - 10 5,892 (2,364 ) 3,528 6,025 (1,684 ) 4,341 Non-compete agreements 5 1,886 (813 ) 1,073 1,839 (433 ) 1,406 Other 20 59 (26 ) 33 60 (24 ) 36 Total $ 100,352 $ (31,932 ) $ 68,420 $ 100,228 $ (27,016 ) $ 73,212 Amortization expense for amortizable intangibles was approximately $6.4 million, $6.0 million and $1.6 million in 2016, 2015 and 2014, respectively. See information regarding intangibles acquired in conjunction with company acquisitions in Note 3. Based on the carrying value at December 31, 2016, future amortization of intangible assets is expected to be as follows for the years ended December 31 (in thousands): 2017 $ 6,481 2018 6,398 2019 6,295 2020 5,138 2021 4,903 Thereafter 39,205 Total $ 68,420
Impairment of Long-Lived Assets (Other than Goodwill)	Impairment of Long-Lived Assets (Other than Goodwill) Our rental fleet, property, plant and equipment, and finite-lived intangibles are reviewed for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may be impaired. (See potential impairment indicators under “Goodwill” above). If this review indicates the carrying value of these assets will not be recoverable, as measured based on estimated undiscounted cash flows over their remaining life, the carrying amount would be adjusted to fair value. The cash flow estimates contain management’s best estimates using appropriate and customary assumptions and projections at the time of evaluation. During the first quarter of 2015, we entered into discussions regarding the possible sale of our wood mobile offices within our North American portable storage segment. The discussions indicated that the fleet might be sold at an amount below carrying value and we conducted a review for impairment for these long-lived assets as of March 31, 2015. Based on this review, an impairment loss was recorded in the quarter ended March 31, 2015. The total impairment of the wood mobile offices was $64.6 million during 2015. See additional discussion regarding the impairment and the divestiture of the wood mobile offices in Note 4. There were no indicators of further impairment at December 31, 2016 or at December 31, 2015.
Purchase Accounting	Purchase Accounting We account for acquisitions under the acquisition method. Under the acquisition method of accounting, we record assets acquired and liabilities assumed at their estimated fair market value on the date of acquisition. Goodwill is measured as the excess of the fair value of the consideration transferred over the fair value of the identifiable net assets. Estimated fair values of acquired assets and liabilities is provisional and could change as additional information is received. We finalize valuations as soon as practicable, but not later than one-year from the acquisition date. Any subsequent changes to purchase price allocations results in a corresponding adjustment to goodwill. The determination of the fair value of intangible assets requires the use of significant judgment with regard to (i) the fair value; and (ii) whether such intangibles are amortizable or non-amortizable and, if amortizable, the period and the method by which the intangible asset will be amortized. We estimate the fair value of acquisition-related intangible assets principally based on projections of cash flows that will arise from identifiable intangible assets of acquired businesses. The projected cash flows are discounted to determine the present value of the assets at the dates of acquisition.
Revenue Recognition	Revenue Recognition Rental revenue is generated from the direct rental of our fleet to our customers, including ancillary revenue such as fleet delivery and pickup. We enter into contracts with our customers to rent equipment based on a monthly rate for our portable storage fleet and a daily, weekly or monthly rate for our specialty containment fleet. Revenues from renting are recognized ratably over the rental period. The rental continues until cancelled by the customer or the Company. Customers may utilize our equipment delivery and pick-up services in conjunction with the rental of equipment, but it is not required. Revenue pursuant to the pick up or delivery of a rented unit is recognized in rental revenue upon completion of the service. When customers are billed in advance, we defer recognition of revenue and record unearned rental revenue at the end of the period. If equipment is returned prior to the end of the contractually obligated period, the excess, if any, between the amount the customer is contractually required to pay, over the cumulative amount of revenue recognized to date, is recognized as incremental revenue upon return. Sales revenue is primarily generated by the sale of new and used units, and to a lesser extent, parts and supplies sold to specialty containment customers. We recognize revenues from sales of units upon delivery when the risk of loss passes, the price is fixed and determinable and collectability is reasonably assured. We sell our units pursuant to sales contracts stating the fixed sales price.
Cost of Sales	Cost of Sales Cost of sales in our consolidated statements of income includes the costs for units we sell, and to a lesser extent the costs of parts and supplies sold to specialty containment customers. Similar costs associated with units that we rent are capitalized in the balance sheet under “Rental fleet”.
Advertising Costs	Advertising Costs Advertising expense was $3.9 million, $4.1 million and $5.2 million in 2016, 2015 and 2014, respectively. The balance of prepaid advertising costs, which are never amortized more than twelve months, was less than $0.1 million at both December 31, 2016 and 2015.
Income Taxes	Income Taxes In preparing our consolidated financial statements, we recognize income taxes in each of the jurisdictions in which we operate. For each jurisdiction, we estimate the actual amount of taxes currently payable or receivable as well as deferred tax assets and liabilities attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided for those deferred tax assets for which it is more likely than not that the related benefits will not be realized. In determining the amount of the valuation allowance, we consider estimated future taxable income as well as feasible tax planning strategies in each jurisdiction. If we determine that we will not realize all or a portion of our deferred tax assets, we will increase our valuation allowance with a charge to income tax expense. Conversely, if we determine that we will ultimately be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all or a portion of the related valuation allowance will be reduced with a credit to income tax expense. We record uncertain tax positions using a two-step process, whereby (1) we determine whether it is more likely than not that the tax positions will be sustained on the basis of the technical merits of the position and (2) for those tax positions that meet the more-likely-than-not recognition threshold, we recognize the largest amount of tax benefit that is more than 50% likely to be realized upon ultimate settlement with the related tax authority. The Company recognizes interest and penalties related to unrecognized tax benefits within the interest expense line and other expense line, respectively, in the accompanying Consolidated Statement of Income. Accrued interest and penalties are included within the related liability lines in the Consolidated Balance Sheet.
Earnings per Share	Earnings per Share Basic earnings per share (“EPS”) is calculated by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated under the treasury stock method. Potential common shares included restricted common stock, which is subject to risk of forfeiture, incremental shares of common stock issuable upon the exercise of stock options and vesting of restricted stock awards. The following table is a reconciliation of net income and weighted-average shares of common stock outstanding for purposes of calculating basic and diluted EPS for the years ended December 31: For the Years Ended December 31, 2016 2015 2014 (In thousands, except per share data) Numerator: Net income $ 47,248 $ 5,574 $ 44,386 Denominator: Weighted average shares outstanding - basic 44,145 44,953 46,026 Dilutive effect of share-based awards 245 507 699 Weighted average shares outstanding - diluted 44,390 45,460 46,725 Earnings per share: Basic $ 1.07 $ 0.12 $ 0.96 Diluted 1.06 0.12 0.95 Basic weighted average number of common shares outstanding does not include restricted stock awards that had not vested of 0.2 million, 0.2 million and 0.3 million shares in 2016, 2015 and 2014, respectively. The following table represents the number of stock options and restricted stock awards that were issued or outstanding but excluded in calculating diluted EPS because their effect would have been anti-dilutive for the years ended December 31: For the Years Ended December 31, 2016 2015 2014 (In thousands) Stock options 2,076 1,135 751 Restricted stock awards 5 1 — Total 2,081 1,136 751
Fair Value Measurements	Fair Value Measurements Fair value is the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants. Fair value is a market-based measurement determined by assumptions that market participants would use in pricing an asset or liability. We categorize each of our fair value measurements in one of the following three levels based on the lowest level of input that is significant to the fair value measurement: Level 1 — Observable inputs such as quoted prices in active markets for identical assets or liabilities; Level 2 — Observable inputs, other than Level 1 inputs in active markets, that are observable either directly or indirectly; and Level 3 — Unobservable inputs for which there is little or no market data, which require the reporting entity to develop its own assumptions. The carrying amounts of cash, cash equivalents, receivables, accounts payable and accrued liabilities approximate fair values based on their short-term nature. The fair values of our revolving credit facility and capital leases are estimated using discounted cash flow analyses, based on our current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to us for bank loans with similar terms and average maturities, the fair value of our revolving credit facility debt and capital leases, which are measured using Level 2 inputs, at December 31, 2016 and 2015 approximated their respective book values. During 2016, we redeemed all $200.0 million aggregate principal amount of our outstanding 7.875% senior notes due December 1, 2020 (“2020 Notes”), and issued $250.0 million aggregate principal amount of 5.875% senior notes due July 1, 2024 (“2024 Notes”). See more information in Note 6. The fair value of our 2020 Notes and 2024 Notes (together, the “Senior Notes”) for the periods presented below is based on their latest sales price at the end of each period obtained from a third-party institution and is Level 2 in the fair value hierarchy as there is not an active market for these Senior Notes. The Senior Notes are presented on the balance sheet net of debt issuance costs. The gross carrying value and the fair value of the Senior Notes are as follows: 2016 2015 (In thousands) Carrying value $ 250,000 $ 200,000 Fair value 258,750 207,000 At December 31, 2016 and 2015, we did not have any financial instruments required to be recorded at fair value on a recurring basis.
Derivatives	Derivatives In the normal course of business, our operations are exposed to fluctuations in interest rates. We have in the past, and may again in the future, address a portion of these risks through a controlled program of risk management that includes the use of derivative financial instruments. The objective of controlling these risks is to limit the impact of fluctuations in interest rates on earnings. At December 31, 2016 and 2015, we did not have any derivative financial instruments.
Share-Based Compensation	Share-Based Compensation We calculate the fair value of stock options using the Black-Scholes-Merton option pricing valuation model, which incorporates various assumptions including volatility, expected life and risk-free interest rates. The fair value of restricted stock awards is estimated as the closing price of our common stock on the date of grant. Compensation related to service-based awards are recognized on a straight-line basis over the vesting period, which is generally three to five years. Compensation expense related to performance-based awards is recognized over the implicit service period of the award based on management’s estimate of the probability of the performance criteria being satisfied, adjusted at each balance sheet date. Expense related to performance-based awards that have multiple vesting dates, is recognized using the accelerated attribution approach, whereby each vesting tranche is treated as a separate award for purposes of determining the implicit service period. Share based compensation expense is reduced for forfeitures which are estimated at the time of grant based on historical experience, and revised in subsequent periods if actual forfeitures differ from estimates.
Foreign Currency Translation and Transactions	Foreign Currency Translation and Transactions For our non-U.S. operations, the local currency is the functional currency. All assets and liabilities are translated into U.S. dollars at period-end exchange rates and all income statement amounts are translated at the average exchange rate for each month within the year.
Impact of Recently Issued Accounting Standards	Impact of Recently Issued Accounting Standards Share-Based Compensation. In March 2016, the Financial Accounting Standards Board (“FASB”) issued a standard intended to simplify several areas of accounting for share-based compensation arrangements, including the income tax impact, classification on the statement of cash flows and forfeitures. This standard is effective for annual and interim periods beginning after December 15, 2016. We will implement this standard in the first quarter of 2017. This standard eliminates the requirement that excess tax benefits be realized before companies can recognize them. As a result, utilizing the modified retrospective method, we expect to record a cumulative-effect adjustment for previously unrecognized excess tax benefits of $18.5 million in the opening balance sheet for 2017, with an offsetting increase to retained earnings (deficit). In addition, the standard allows us to make a policy election to either continue to reduce share-based compensation expense for forfeitures in future periods, or to recognize forfeitures as they occur. We have chosen to record forfeitures as they occur and will record immaterial adjustments to reflect a cumulative-effect adjustment for the difference between the fair value estimate of awards historically expected to be forfeited and the fair value estimate of awards actually forfeited. This standard also requires all excess tax benefits and tax deficiencies associated with the exercise of stock options and vesting of restricted stock to be recorded as income tax expense or benefit. Increases and decreases in the aggregate intrinsic value (or negative value) of such activity could introduce volatility in our effective tax rate. We do not expect the remaining provisions of the new guidance to have a material effect on our consolidated financial statements. Leases . In February 2016, FASB issued a standard on lease accounting requiring a lessee to recognize assets and liabilities on the balance sheet for leases with lease terms greater than 12 months. This standard is effective for annual and interim periods beginning after December 15, 2018. Early adoption is permitted and the standard requires the use of a modified retrospective transition method. While we are continuing to evaluate all potential impacts of the standard, we do not believe the accounting for our contractual rental revenue will be materially affected by the adoption of this standard. We anticipate the lessee accounting for operating leases under the standard will have a material effect on our statement of financial position. Simplifying the Presentation of Debt Issuance Costs. In April 2015, FASB issued accounting guidance on the presentation of debt issuance costs in the balance sheet. This standard requires that certain 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. The recognition and measurement guidance for debt issuance costs are not affected by this guidance. We adopted this guidance during 2016. As a result, unamortized debt issuance costs of $4.8 million and $2.4 million as of December 31, 2016 and December 31, 2015, respectively, have been deducted from the carrying amount of the Senior Notes in our balance sheet. Unamortized debt issuance costs related to our revolving credit facility are included in other assets. Revenue from Contracts with Customers. In May 2014, FASB issued an accounting standard on revenue from contracts with customers. The standard provides a single model for revenue arising from contracts with customers and supersedes current revenue recognition guidance. The standard requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of goods or services and is effective for annual and interim periods beginning after December 15, 2017. Early adoption is permitted for the annual and interim periods beginning after December 15, 2016, but not prior to that time. The revenue recognition standard permits the use of either the retrospective or cumulative effect transition method. While we are continuing to assess all potential impacts of the standard, we currently believe the majority of our revenue, as relates to contractual rental revenue, is excluded from the scope of this standard, and the accounting for the remaining revenue streams will not be materially affected. Accordingly, we do not anticipate that the adoption of this standard will have a material impact on our consolidated financial statements. We expect to utilize the modified retrospective adoption and recognize the cumulative effect of initially applying the standard, if any, as an adjustment to the opening balance of retained earnings at the date of initial application.
Income Tax Uncertainties, Policy	Uncertain tax positions are recognized and measured using a two-step approach. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation process, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement.
Segment Reporting, Policy	Prior to the ETS Acquisition, our operations were comprised of two reportable segments: North America and the U.K., both of which offer portable storage solutions. Discrete financial data on each of our products is not available and it would be impractical to collect and maintain financial data in such a manner. As a result of the ETS Acquisition, we established a new specialty containment reportable segment. ETS operations are included in our results of operations for all of 2016 and 2015, and the portion of 2014 subsequent to the acquisition date, which is less than one month. The results for each segment are reviewed discretely by our chief operating decision maker. We operate in the U.S., U.K. and Canada. All of our locations operate in their local currency and, although we are exposed to foreign exchange rate fluctuation in foreign markets where we rent and sell our products, we do not believe such exposure will have a significant impact on our results of operations. Revenues recognized by our U.S. locations were $424.4 million, $438.4 million and $353.2 million for the twelve months ended December 31, 2016, 2015 and 2014, respectively.

(“Water Movers”). With input from an independent third party with extensive expertise and experience in this area, we determined lives for the two customer groups based upon historical and expected customer attrition rates, resulting in an expected useful life of 15 years for the Water Movers customer relationships, which were valued at $14.9 million, and an expected useful life of 20 years for the remaining ETS customer relationships, which were valued at $54.3 million. During our assessment, we evaluated annual historical sales data from 2009 through December 2014 for Water Movers, and 2008 through December 2014 for the remaining ETS customers. (2) All of the goodwill related to the ETS Acquisition was assigned to our specialty containment segment. The goodwill arising from the acquisition consists largely of ETS' going-concern value, the value of ETS’ assembled workforce, new customer relationships expected to arise from the acquisition, and operational synergies and economies of scale that we expect to realize from the acquisition. Goodwill from other acquisitions related to the North America portable storage segment. (3) Included in other assets for the ETS Acquisition are accounts receivable with contractual amounts totaling $24.3 million. We estimated that $0.6 million will be uncollectible, and valued acquired accounts receivable at $23.7 million.

[1]	All of the goodwill related to the ETS Acquisition was assigned to our specialty containment segment. The goodwill arising from the acquisition consists largely of ETS' going-concern value, the value of ETS’ assembled workforce, new customer relationships expected to arise from the acquisition, and operational synergies and economies of scale that we expect to realize from the acquisition. Goodwill from other acquisitions related to the North America portable storage segment.
[2]	Included in other assets for the ETS Acquisition are accounts receivable with contractual amounts totaling $24.3 million. We estimated that $0.6 million will be uncollectible, and valued acquired accounts receivable at $23.7 million.
[3]	The following table reflects the estimated fair values and useful lives of intangible assets related to the ETS Acquisition identified based on our preliminary purchase accounting assessments: Estimated Life (Years) Customer relationships 15 - 20 Trade names/trademarks 5 - 10 Non-compete agreements 5 Customer relationships acquired in conjunction with the ETS Acquisition were evaluated separately for the wholly owned subsidiary Water Movers, Inc. (“Water Movers”). With input from an independent third party with extensive expertise and experience in this area, we determined lives for the two customer groups based upon historical and expected customer attrition rates, resulting in an expected useful life of 15 years for the Water Movers customer relationships, which were valued at $14.9 million, and an expected useful life of 20 years for the remaining ETS customer relationships, which were valued at $54.3 million. During our assessment, we evaluated annual historical sales data from 2009 through December 2014 for Water Movers, and 2008 through December 2014 for the remaining ETS customers.
