Mobile Mini, its Operations and Summary of Significant Accounting Policies	'
	(1) Mobile Mini, its Operations and Summary of Significant Accounting Policies
	Organization and Special Considerations
	Mobile Mini, Inc., a Delaware corporation, is a leading provider of portable storage solutions. In these notes, the terms “Mobile Mini” and the “Company” refer to Mobile Mini, Inc. At December 31, 2013, Mobile Mini has a fleet of portable storage and office units and operates throughout the U.S., Canada and the U.K. The Company’s portable storage products offer secure, temporary storage with immediate access. The Company has a diversified customer base, including large and small retailers, construction companies, medical centers, schools, utilities, distributors, the military, hotels, restaurants, entertainment complexes and households. The Company’s customers use its 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.
	Principles of Consolidation
	The consolidated financial statements include the accounts of Mobile Mini and its wholly owned subsidiaries. The Company does not have any subsidiaries in which it does not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated.
	Discontinued Operation
	In December 2013, the Company sold the subsidiary comprising its Netherlands operation. The Netherlands operation is reflected as discontinued operation for all periods presented and all prior period amounts have been recast to reflect this transaction. See Note 18.
	Revenue Recognition
	The Company recognizes revenue, including multiple element arrangements, in accordance with the provisions of applicable accounting guidance. The Company generates revenue from the leasing of portable storage containers and office units, as well as other services such as pickup and delivery. In most instances, the Company provides some of the above services under the terms of a single customer lease agreement. The Company also generates revenue from the sale of containers and office units.
	The Company’s lease arrangements typically include lease deliverables such as the lease of container or office unit and ancillary charges related to the leased container or office unit during the lease term. Arrangement consideration is allocated between lease deliverables and non-lease deliverables based on the relative estimated selling (leasing) price of each deliverable. Estimated selling (leasing) price of the lease deliverables is based on the price of those deliverables when sold separately (vendor-specific objective evidence). Because delivery and pick-up services are not sold separately by the Company, the estimated selling price of those deliverables is based on prices charged for similar services provided by other vendors (third party evidence of fair value).
	The arrangement consideration allocated to lease deliverables is accounted for pursuant to accounting guidance on leases. Such revenues from leases are billed in advance and recognized as earned, on a straight line basis over the lease period specified in the associated lease agreement. Lease agreement terms typically span several months or longer. Because the term of the agreements can extend across financial reporting periods, when leases are billed in advance, the Company defers recognition of revenue and records unearned leasing revenue at the end of reporting periods so that rental revenue is included in the appropriate period. Transportation revenue from container and mobile office delivery service is recognized on the delivery date and is recognized for pick-up service when the container or office unit is picked-up.
	The Company recognizes revenues from sales of containers and office units upon delivery when the risk of loss passes, the price is fixed and determinable and collectability is reasonably assured. The Company sells its products pursuant to sales contracts stating the fixed sales price with its customers.
	Cost of Sales
	Cost of sales in the Company’s consolidated statements of income includes only the costs for units it sells. Similar costs associated with the portable storage units that the Company leases are capitalized on its balance sheet under “Lease Fleet”.
	Advertising Costs
	All non-direct-response advertising costs are expensed as incurred. Yellow page advertising is capitalized when paid and amortized over the period in which the benefit is derived. At December 31, 2012 and 2013, prepaid advertising costs were approximately $0.6 million and $0.2 million, respectively. The amortization period of the prepaid balance never exceeds 12 months. Advertising expense was $9.5 million, $12.3 million and $5.8 million in 2011, 2012 and 2013, respectively.
	Receivables and Allowance for Doubtful Accounts
	Receivables primarily consist of amounts due from customers from the lease or sale of containers throughout the U.S., Canada and the U.K. Mobile Mini records an estimated provision for bad debts through a charge to operations in amounts of its estimated losses expected to be incurred in the collection of these accounts. The Company reviews the provision for adequacy monthly. The estimated losses are based on historical collection experience and evaluation of past-due account agings. Specific accounts are written off against the allowance when management determines the account is uncollectible. The Company requires a security deposit on most leased office units to cover the cost of damages or unpaid balances, if any.
	Concentration of Credit Risk
	Financial instruments which potentially expose the Company to concentrations of credit risk consist primarily of receivables. Concentration of credit risk with respect to receivables is limited due to the Company’s large number of customers spread over a broad geographic area in many industry sectors. No single customer accounts for more than 10.0% of our receivables at December 31, 2012 and 2013. Receivables related to its sales operations are generally secured by the product sold to the customer. Receivables related to its leasing operations are primarily small month-to-month amounts. The Company has the right to repossess leased 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 (FIFO) method) or market. Market is the lower of replacement cost or net realizable value. Inventories primarily consist of raw materials, supplies, work-in-process and finished goods, all related to the manufacturing, remanufacturing and maintenance, primarily for the Company’s lease fleet and its units held for sale. Raw materials principally consist of raw steel, wood, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes. Work-in-process primarily represents units being built that are either pre-sold or being built to add to its lease fleet upon completion. Finished portable storage units primarily represent ISO (International Organization for Standardization) containers held in inventory until the containers are either sold as is, remanufactured and sold, or units in the process of being remanufactured to be compliant with the Company’s lease fleet standards before transferring the units to its lease fleet. There is no certainty when the Company purchases the containers whether they will ultimately be sold, remanufactured and sold, or remanufactured and moved into its lease fleet. Units that are determined to go into the Company’s lease fleet undergo an extensive remanufacturing process that includes installing its proprietary locking system, signage, painting and sometimes its proprietary security doors.
	Inventories at December 31 consisted of the following:
			2012			2013
			(In thousands)
	Raw materials and supplies		$	14,587		$	16,586
	Work-in-process			336			197
	Finished portable storage units			4,452			1,961
	Inventories(1)		$	19,375		$	18,744
	-1	Includes an impairment charge of $1.2 million recorded in the second quarter of 2013. (See Note 17).
	Property, Plant and Equipment
	Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is provided using the straight-line method over the assets’ estimated useful lives. Residual values are determined when the property is constructed or acquired and range up to 25%, depending on the nature of the asset. At the end of the second quarter of 2013, management reevaluated the Company’s depreciation policies and modified the useful life and residual values on forklifts, which became effective on July 1, 2013. Estimated residual values do not cause carrying values to exceed net realizable value. The Company’s depreciation expense related to property, plant and equipment for 2011, 2012 and 2013 was $11.7 million, $12.2 million and $12.7 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 leasing, selling and general expenses in the Consolidated Statements of Income.
	Property, plant and equipment at December 31 consisted of the following:

	-2	Improvements made to leased properties are depreciated over the lesser of the estimated remaining life or the remaining term of the respective lease.
	Other Assets and Intangibles
	Other assets and intangibles primarily represent deferred financing costs and intangible assets from acquisitions of $51.4 million at December 31, 2012 and $51.6 million at December 31, 2013, excluding accumulated amortization of $33.6 million at December 31, 2012 and $38.1 million at December 31, 2013. Deferred financing costs are amortized over the term of the agreement, and intangible assets are amortized on a straight-line basis, typically from five to 20 years, depending on its useful life. Intrinsic values assigned to customer relationships and trade names are amortized on an accelerated basis, typically over 15 years.
	The following table reflects balances related to other assets and intangible assets for the years ended December 31:
			2012									2013

	Amortization expense for deferred financing costs was approximately $4.1 million, $3.2 million and $2.8 million in 2011, 2012 and 2013, respectively. In addition, in 2012, the Company wrote off $1.9 million of deferred financing costs related to the redemption of our 6.875% senior notes due 2015 and a portion of deferred financial costs related to our prior credit agreement. The annual amortization of deferred financing costs is expected to be $2.8 million in 2014, $2.8 million in 2015, $2.8 million in 2016, $0.9 million in 2017, $0.5 million in 2018 and $1.0 million thereafter.
	Amortization expense for all other intangibles was approximately $3.0 million, $2.2 million and $1.6 million in 2011, 2012 and 2013, respectively. Based on the carrying value at December 31, 2013, and assuming no subsequent impairment of the underlying assets, the annual amortization expense is expected to be $1.0 million in 2014, $0.7 million in 2015, $0.5 million in 2016, $0.2 million in 2017, $0.1 million in 2018 and $0.1 million thereafter.
	Income Taxes
	Mobile Mini utilizes the liability method of accounting for income taxes where deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Income tax expense includes both taxes payable for the period and the change during the period in deferred tax assets and liabilities.
Earnings per Share
The Company’s preferred stock, if applicable, participates in distributions of earnings on the same basis as shares of common stock. As such, the Company adopted the accounting guidance for the standards regarding the computation of earnings per share (“EPS”) for securities other than common stock that contractually entitle the holder to participate in dividends and earnings of the Company. Earnings for the period are required to be allocated between the common and preferred stockholders based on their respective rights to receive dividends. Basic net income per share is then calculated by dividing income allocable to common stockholders by the weighted average number of common shares outstanding, net of shares subject to repurchase by the Company, during the period. The Company is not required to present basic and diluted net income per share for securities other than common stock. Accordingly, the following net income per share amounts only pertain to the Company’s common stock. The Company calculates diluted net income per share under the if-converted method unless the conversion of the preferred stock is anti-dilutive to basic net income per share. To the extent the inclusion of preferred stock is anti-dilutive, the Company calculates diluted net income per share under the two-class method. Potential common shares include restricted common stock, which is subject to risk of forfeiture and incremental shares of common stock issuable upon the exercise of stock options and upon the conversion of convertible preferred stock using the treasury stock method.
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:

Long Lived Assets
Mobile Mini reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be fully recoverable. 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. The Company did not recognize any impairment losses in the year ended December 31, 2012.
In the second quarter of 2013, with a strategic focus on increasing return on capital and a move toward a rent-ready business model, the Company conducted an assessment of the lease fleet and rolling stock equipment. Management determined that certain of these units were either non-core to their leasing strategy or were uneconomic to repair. In connection with this evaluation, management determined to place the assets for sale, resulting in a non-cash impairment charge on long-lived assets of $37.6 million in the second quarter of 2013. (See Note 17).
Goodwill
Purchase prices of acquired businesses have been allocated to the assets and liabilities acquired based on the 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 were allocated to goodwill. Acquisitions of businesses under asset purchase agreements results in the goodwill relating to business acquisition being deductible for income tax purposes over 15 years even though goodwill is not amortized for financial reporting purposes.
The Company evaluates goodwill periodically to determine whether events or circumstances have occurred that would indicate goodwill might be impaired. The Company originally had assigned its goodwill to each of its three reporting units (North America, the U.K. and The Netherlands). At December 31, 2013, only North America and the U.K. have goodwill subject to impairment testing. The Company performs an annual impairment test on goodwill at December 31. In addition, the Company will perform impairment tests during any reporting period in which events or changes in circumstances indicate that an impairment may have incurred. In assessing the fair value of the reporting units, the Company considers both the market and income approaches. 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 expenditure, tax payments and discount rates. Each approach was given equal weight in arriving at the fair value of the reporting unit. As of December 31, 2013, management assessed qualitative factors and determined it is more likely than not each of the Company’s reporting units 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 required.
If the two step impairment test is necessary, the Company is required to determine the implied fair value of the goodwill and compare it to the carrying value of the goodwill. The Company would allocate the fair value of the reporting units 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. At December 31, 2013, $450.8 million of the goodwill relates to the North America reporting unit, and $68.4 million relates to the U.K. reporting unit.
The following table shows the activity and balances related to goodwill from January 1, 2012 to December 31, 2013:
		Goodwill

-2	Represents foreign currency translation adjustments related to the U.K. reporting unit.
-3	Represents adjustments to the fair values originally assigned to assets and liabilities assumed for the acquired businesses in December 2011.
Fair Value of Financial Instruments
The Company determines the estimated fair value of financial instruments using available market information and valuation methodologies. Considerable judgment is required in estimating fair values. Accordingly, the estimates may not be indicative of the amounts the Company could realize in current market exchanges.
The carrying amounts of cash, receivables, accounts payable and accrued liabilities approximate fair values based on the liquidity of these financial instruments or based on their short-term nature. The carrying amounts of the Company’s borrowings under its credit facility, notes payable and capital leases approximate fair value. The fair values of the Company’s revolving credit facility, notes payable and capital leases are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company’s revolving credit facility debt, notes payable and capital leases at December 31, 2012 and 2013 approximated their respective book values and are considered Level 2 in the fair value hierarchy described in Note 2.
The fair value of the Company’s $200.0 million aggregate principal amount of 7.875% senior notes due 2020 (the “2020 Notes” or the “Senior Notes”) is based on the latest sales price of such notes at the end of each period obtained from a third-party institution and is considered Level 2 in the fair value hierarchy described in Note 2, as there is not an active market for such notes.
The carrying value and the fair value of the Company’s Senior Notes are as follows:
		December 31,			December 31,
		2012			2013
		(In thousands)
Carrying value		$	200,000		$	200,000
Fair value		$	219,000		$	217,300
Deferred Financing Costs
Included in other assets and intangibles are deferred financing costs of approximately $13.6 million and $10.8 million, net of accumulated amortization of $14.5 million and $17.3 million, at December 31, 2012 and 2013, respectively. Costs of obtaining long-term financing, including the Company’s Credit Agreement (as defined below) (See Note 4), are amortized over the term of the related debt, using the straight-line method. Amortizing the deferred financing costs using the straight-line method approximates the effective interest method.
Derivatives
In the normal course of business, the Company’s operations are exposed to fluctuations in interest rates. The Company historically addressed 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.
The Company’s primary interest rate risk exposure results from changes in short-term U.S. dollar interest rates. In an effort to manage interest rate exposures, the Company may enter into interest rate swap agreements that convert its floating rate debt to a fixed-rate, which are typically designated as cash flow hedges. Interest expense on the notional amounts under these agreements is accrued using the fixed rates identified in the swap agreements. At December 31, 2012 and 2013, the Company did not have any interest rate swap agreements.
Share-Based Compensation
At December 31, 2013, the Company had one active share-based employee compensation plan. There are two expired compensation plans, one of which still has outstanding options subject to exercise or termination. No additional options can be granted under the expired plans. Stock option awards under these plans are granted with an exercise price per share equal to the fair market value of the Company’s common stock on the date of grant. Each outstanding option must expire no more than ten years from the date it was granted, unless exercised or forfeited before the expiration date, and are granted with vesting periods ranging from three to four and a half years. The total value of the Company’s stock option awards is expensed over the related employee’s service period on a straight-line basis, or if subject to performance conditions, then the expense is recognized using the accelerated attribution method.
The Company uses the modified prospective method and does not recognize a deferred tax asset for any excess tax benefit that has not been realized related to stock-based compensation deductions. The Company adopted the with-and-without approach with respect to the ordering of tax benefits realized. In the with-and-without approach, the excess tax benefit related to stock-based compensation deductions will be recognized in additional paid-in capital only if an incremental tax benefit would be realized after considering all other tax benefits presently available to us. Therefore, the Company’s net operating loss carryforward will offset current taxable income prior to the recognition of the tax benefit related to stock-based compensation deductions. In 2012 and 2013, there were $1.3 million and $4.2 million, respectively, of excess tax benefits related to stock-based compensation, which were not realized under this approach. Once the Company’s net operating loss carryforward is utilized, these aggregate excess tax benefits, totaling $14.2 million, may be recognized in additional paid-in capital.
Foreign Currency Translation and Transactions
For Mobile Mini’s 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.
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. The most significant estimates included within the financial statements are the allowance for doubtful accounts, the estimated useful lives and residual values on the lease fleet and property, plant and equipment, goodwill and other asset impairments and certain accrued liabilities.
Impact of Recently Issued Accounting Standards
Comprehensive Income. In June 2011, the Financial Accounting Standards Board (“FASB”) issued an amendment to the existing guidance on the presentation of comprehensive income. Under the amended guidance, an entity is required to present the effect of reclassification adjustments out of accumulated other comprehensive income in both net income and other comprehensive income in the financial statements. In February 2013, the FASB issued an amendment to this provision which is effective on a prospective basis for fiscal years, and interim periods within those years, beginning after December 15, 2012. The adoption of this amendment did not have a material impact on our consolidated financial statements and related disclosures.
Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists. In July 2013, the FASB issued this accounting guidance on the financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. The guidance is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013, with an option for early adoption. The Company intends to adopt this guidance at the beginning of its first quarter of fiscal year 2014, and does not anticipate any material impact on its consolidated financial statements and disclosures.

	(2) Fair Value Measurements
	The Company defines fair value as 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 that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company adopted the suggested accounting guidance for the three levels of inputs that may be used to measure fair value:
		Level 1 —	Observable input 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.
	At December 31, 2012 and 2013, the Company did not have any financial instruments required to be recorded at fair value on a recurring basis.

Lease Fleet	'
	(3) Lease Fleet
	Mobile Mini’s lease fleet primarily consists of remanufactured, modified and manufactured steel storage containers, steel security offices, steel combination offices and wood mobile offices that are leased to customers under short-term operating lease agreements with varying terms. Depreciation is provided using the straight-line method over the units’ estimated useful life, after the date the Company put the unit in service, and are depreciated down to their estimated residual values. The Company’s depreciation policy on its steel units uses an estimated useful life of 30 years with an estimated residual value of 55%. Wood mobile office units are depreciated over 20 years down to a 50% residual value. Van trailers, which are a small part of the Company’s fleet, are depreciated over seven years to a 20% residual value. Van trailers and other non-core assets are typically only added to the fleet in connection with acquisitions of portable storage businesses. In the opinion of management, estimated residual values do not cause carrying values to exceed net realizable value. The Company continues to evaluate these depreciation policies as more information becomes available from other comparable sources and its own historical experience. The Company’s depreciation expense related to its lease fleet for 2011, 2012 and 2013 was $20.9 million, $21.6 million and $21.2 million, respectively. At December 31, 2012 and 2013, all of the Company’s lease fleet units were pledged as collateral under the Credit Agreement. Normal repairs and maintenance to the portable storage containers and mobile office units are expensed as incurred.

	(4) Lines of Credit
	On February 22, 2012, the Company entered into a $900.0 million ABL Credit Agreement with Deutsche Bank AG New York Branch and other lenders party thereto (the “Credit Agreement”). The Credit Agreement provides for a five-year, revolving credit facility and all amounts outstanding under the Credit Agreement are due on February 22, 2017. The obligations of Mobile Mini and its subsidiary guarantors under the Credit Agreement are secured by a blanket lien on substantially all of its 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 the Company’s option at either: (i) LIBOR plus a defined margin, or (ii) the Agent bank’s prime rate plus a margin. The applicable margin for each type of loan is based on an availability-based pricing grid and ranges from 1.75% to 2.25% for LIBOR loans and 0.75% to 1.25% for base rate loans at each measurement date. As of December 31, 2013, the applicable margins are 2.00% for LIBOR loans and 1.00% for base rate loans and will be remeasured at the end of the next measurement date, which is within 10 days following the end of each fiscal quarter.
	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 lease 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 or its subsidiary assets; (ii) repurchase or pay dividends or make certain other restricted payments on capital stock and certain other securities, prepay certain indebtedness or make acquisitions or other investments subject to Payment Conditions (as defined in the Credit Agreement); and (iii) incur additional indebtedness or engage in certain other types of financing transactions. Payment Conditions allow restricted payments and acquisitions to occur without financial covenants as long as the Company has $225.0 million of pro forma excess borrowing availability under the Credit Agreement. The Company must also comply with specified financial maintenance covenants and affirmative covenants only if the Company falls below $90.0 million of borrowing availability levels with set permitted values for the Debt Ratio and Fixed Charge Coverage Ratio (as defined in the Credit Agreement). The Company was in compliance with the terms of the Credit Agreement as of December 31, 2013 and was above the minimum borrowing availability threshold and therefore not subject to any financial maintenance covenants.
	The weighted average interest rate under the lines of credit was approximately 2.5% in 2012 and 2.2% in 2013. The average outstanding balance was approximately $391.4 million and $386.6 million during 2012 and 2013, respectively. In 2012, the Company redeemed $150.0 million aggregate principal amount of 6.875% senior notes due 2015 by drawing down funds under the Credit Agreement. At December 31, 2013 the Company had approximately $319.3 million of borrowings outstanding and $573.3 million additional borrowing availability under the Credit Agreement, based upon borrowing base calculations as of such date.

	At December 31, 2012 and 2013, obligations under capital leases for certain transportation, technology and office related equipment were $0.6 million and $8.8 million, respectively. The lease agreements provide the Company with a purchase option at the end of the lease term. The leases have been capitalized using interest rates ranging from approximately 1.8% to 8.1%. The leases are secured by the equipment under lease. Assets recorded under capital lease obligations totaled approximately $2.8 million as of December 31, 2012 and $10.2 million as of December 31, 2013. Related accumulated amortization totaled approximately $1.4 million as of December 31, 2012 and $1.1 million as of December 31, 2013. The assets acquired under capital leases and related accumulated amortization is 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.

	A deferred U.S. tax liability has not been provided on the undistributed earnings of certain foreign subsidiaries because it is Mobile Mini’s intent to permanently reinvest such earnings. Undistributed earnings of foreign subsidiaries, which have been or are intended to be permanently invested, aggregated approximately $20.1 million and $25.5 million as of December 31, 2012 and 2013, respectively. A net deferred tax liability of approximately $14.4 million and $14.4 million related to the Company’s U.K. operations has been combined with the net deferred tax liabilities of its U.S. operations in the Consolidated Balance Sheets at December 31, 2012 and 2013, respectively. A reconciliation of the U.S. federal statutory rate to Mobile Mini’s effective tax rate for the years ended December 31 is as follows:
		2011			2012			2013
	U.S. federal statutory rate		35	%		35	%		35	%
	State taxes, net of federal benefit		3.5			3.5			3.5

	Foreign rate differential		(2.2	)		(2.8	)		(2.3	)
			34.7	%		35	%		32.7	%
	At December 31, 2013, Mobile Mini had U.S. federal net operating loss carryforwards on its federal tax return of approximately $264.1 million, which expire if unused from 2022 to 2031. At December 31, 2013, the Company had net operating loss carryforwards on the various states’ tax returns in which it operates totaling $154.8 million, which expire if unused from 2014 to 2031. At December 31, 2012 and 2013, the Company’s net operating losses carrying forward for tax return purposes include $10.1 million and $14.2 million of excess tax benefits from employee stock option exercises that are a component of its net operating loss carryforward. Additional paid in capital will be increased by an equivalent amount if and when such excess tax benefits are realized. Management evaluates the ability to realize its deferred tax assets on a quarterly basis and adjusts the amount of its valuation allowance if necessary. Accelerated tax amortization primarily relates to amortization of goodwill for income tax purposes.
	Mobile Mini adopted a two-step approach to recognizing and measuring uncertain tax positions. 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.
	The Company files U.S. federal tax returns, U.S. state tax returns, and foreign tax returns. The Company has identified its U.S. Federal tax return as its “major” tax jurisdiction. For the U.S. Federal return, the Company’s tax years for 2010, 2011 and 2012 are subject to tax examination by the U.S. Internal Revenue Service through September 15, 2014, 2015 and 2016, respectively. No reserves for uncertain income tax positions have been recorded. The Company does not anticipate that the total amount of unrecognized tax benefit related to any particular tax position will change significantly within the next 12 months.
	In July 2013, the U.K.’s government authorized another reduction in the corporate income tax rate from the statutory rate of 23%, authorized in 2012, to 20%. In July 2012, the U.K.’s government reduced the corporate income tax rate from the statutory rate of 25% to 23%. These rate reductions only affected the Company’s U.K. operations and reduced the Company’s deferred tax liability in the U.K. by approximately $1.2 million and $1.9 million in 2012 and 2013, respectively. The tax reductions are reflected at the enacted rate in effect at the estimated date such amounts will be payable. The benefit of these rate changes is included in the 2012 and 2013 tax provisions.
	The Company’s policy for recording interest and penalties associated with audits is to record such items as a component of income before taxes. Penalties and associated interest costs, if any, are recorded in leasing, selling and general expenses in its Consolidated Statements of Income.
	As a result of stock ownership changes during the years presented, it is possible that the Company has undergone a change in ownership for federal income tax purposes, which can limit the amount of net operating loss currently available as a deduction. Management has 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.
	Mobile Mini paid income taxes of approximately $0.8 million in 2011 and 2012 and $1.1 million in 2013. These amounts are lower than the recorded expense in the years due to net operating loss carryforwards and general business credit utilization.

Share-Based Compensation	'
	(10) Share-Based Compensation
	The Company awarded stock options and nonvested share-awards under the existing share-based compensation plans. The majority of these options and nonvested share-awards vest in equal annual installments over a four to five year period. The total value of these options and nonvested share-awards is expensed on a straight-line basis over the service period of the employees receiving the grants. The “service period” is the time during which the employees receiving grants must remain employees for the shares granted to fully vest.
	The Company also grants certain executive officers stock options and nonvested share-awards with vesting subject to performance conditions. Vesting of these grants is dependent upon the respective officers fulfilling the service period requirements as well as the Company achieving certain yearly adjusted EBITDA targets in each of the performance periods (three to four years) after the grant is awarded. EBITDA is defined as net income before discontinued operation, net of tax, interest expense, income taxes, depreciation and amortization and debt restructuring or extinguishment expense, including any write-off of deferred financing costs, and further adjusted for specific transactions, including non-cash share-based compensation expense, to arrive at adjusted EBITDA. For performance-based grants, the Company is required to assess the probability that such performance conditions will be met. If the likelihood of the performance conditions being met is deemed probable, the Company will recognize the expense using the accelerated attribution method. The accelerated attribution method could result in as much as 60% of the total value of the shares being recognized in the first year of the service period if the future performance-based targets are assessed as probable of being met. There was no adjustment in the past three years to reflect any underperformance for share-based compensation expense related to nonvested share-awards with vesting subject to performance conditions.
	Share-based payment expense related to the vesting of options and nonvested share-awards was approximately $6.5 million, $9.6 million and $14.7 million for 2011, 2012 and 2013, respectively. As of December 31, 2013, total unrecognized compensation cost related to stock option awards was approximately $15.2 million and the related weighted-average period over which it is expected to be recognized is approximately 1.7 years. As of December 31, 2013, the unrecognized compensation cost related to nonvested share-awards was approximately $9.7 million, which is expected to be recognized over a weighted-average period of approximately 2.6 years.
	The cash flows resulting from the tax benefits arising from tax deductions in excess of the compensation cost recognized from the exercise of stock options (excess tax benefits) are classified as financing cash flows. As of December 31, 2013, the Company had no tax benefits arising from tax deductions in excess of the compensation cost recognized because the benefit has not been “realized” given that the Company currently has net operating loss carryforwards and follows the with-and-without approach with respect to the ordering of tax benefits realized.

	The aggregate intrinsic value of options exercised during the period ended December 31, 2011, 2012 and 2013 was $0.8 million, $2.7 million and $9.0 million, respectively.
	The fair value of each stock option award is estimated on the date of the grant using the Black-Scholes option pricing model. The following are the key assumptions used for the period noted:
		2012			2013
	Risk-free interest rate		0.8	%	0.7% – 1.5%
	Expected life of the options (years)		6		6.0 – 7.0
Expected stock price volatility		41.8	%	41.1% – 46.3%
Expected dividend rate		0	%	0.0% – 1.8%
The Black-Scholes option valuation model was developed for use in estimating the fair value of short-traded options that have no vesting restrictions and are fully transferable. In addition, option valuation models require the input of assumptions including expected stock price volatility. The risk-free interest rate is based on the U.S. Treasury security rate in effect at the time of the grant. The expected life of the options and volatility rates are based on our historical data. Historically, we had not paid cash dividends and therefore have assumed a zero dividend rate in 2012.
The weighted average fair value of stock options granted was $6.84, $8.56 and $10.59 for the period ended December 31, 2011, 2012 and 2013, respectively.

	Stock Option and Equity Incentive Plans
	In August 1999, the Company’s Board of Directors approved the Mobile Mini, Inc. 1999 Stock Option Plan (the “1999 Plan”), which expired (with respect to granting additional options) in August 2009. As of December 31, 2013, there were outstanding options to acquire 0.1 million shares under the 1999 Plan. The plan and amendments were approved by the stockholders at annual meetings. Awards granted under the 1999 Plan may be incentive stock options, which are intended to meet the requirements of Section 422 of the Internal Revenue Code, nonstatutory stock options or shares of restricted stock awards. Incentive stock options may be granted to the Company’s officers and other employees. Nonstatutory stock options may be granted to directors and employees, and to non-employee service providers and nonvested share-awards may be made to officers and other employees.
	In February 2006, Mobile Mini’s Board of Directors approved the 2006 Equity Incentive Plan (the “2006 Plan”) that was subsequently approved by the stockholders at the Company’s 2006 Annual Meeting. At the Annual Stockholders’ Meeting in June 2009, the stockholders approved an amendment to the 2006 Plan to increase the maximum number of shares that could be issued by an additional 3.0 million shares. In July 2013, the stockholders at the 2013 Annual Shareholders’ Meeting approved an amendment to the 2006 Plan to increase the maximum number of shares that could be issued by an additional 2.0 million shares. The 2006 Plan is an “omnibus” stock plan permitting a variety of equity programs designed to provide flexibility in implementing equity and cash awards, including incentive stock options, nonqualified stock options, nonvested share-awards, restricted stock units, stock appreciation rights, performance stock, performance units and other stock-based awards. Participants in the 2006 Plan may be granted any one of the equity awards or any combination of them, as determined by the Board of Directors or the Compensation Committee. The 2006 Plan, as amended, has reserved 6.2 million shares of common stock for issuance. As of December 31, 2013, there were outstanding options to acquire 0.5 million shares under the 2006 Plan.
	The purpose of these plans is to attract and retain the best available personnel for positions of substantial responsibility and to provide incentives to, and to encourage ownership of stock by, Mobile Mini’s management and other employees. The Board of Directors believes that stock options and other share-based awards are important to attract and to encourage the continued employment and service of officers and other employees and encourage them to devote their best efforts to the Company’s business, thereby advancing the interest of its stockholders.
	The option exercise price for all options granted under these plans may not be less than 100% of the fair market value of the common stock on the date of grant of the option (or 110% in the case of an incentive stock option granted to an optionee beneficially owning more than 10% of the outstanding common stock). The maximum option term is ten years (or five years in the case of an incentive stock option granted to an optionee beneficially owning more than 10% of the outstanding common stock). Payment for shares purchased under these plans is made in cash. Options may, if permitted by the particular option agreement, be exercised by directing that certificates for the shares purchased be delivered to a licensed broker as agent for the optionee, provided that the broker tenders to Mobile Mini, cash or cash equivalents equal to the option exercise price.
	The plans are administered by the Compensation Committee of Mobile Mini’s Board of Directors. The Compensation Committee is comprised of independent directors. They determine whether options will be granted, whether options will be incentive stock options, nonstatutory option, restricted stock, or performance stock, which officers, employees and service providers will be granted options, the vesting schedule for options and the number of options to be granted. Each outstanding option must expire no more than ten years from the date it was granted, unless exercised or forfeited before the expiration date, and are granted with vesting periods ranging from 3 to 4.5 years. Each non-employee director serving on the Company’s Board of Directors receives an automatic award of shares of Mobile Mini’s common stock equivalent to $82,500, or $120,000 for the Chairman of the Board, based on the closing price of the Company’s common stock on August 1 of that year, or the following trading day if August 1 is not a trading day. These awards vest 100% when granted.
	The Board of Directors may amend the plans at any time, except that approval by Mobile Mini’s stockholders may be required for an amendment that increases the aggregate number of shares which may be issued pursuant to each plan, changes the class of persons eligible to receive incentive stock options, modifies the period within which options may be granted, modifies the period within which options may be exercised or the terms upon which options may be exercised, or increases the material benefits accruing to the participants under each plan. The Board of Directors may terminate or suspend the plans at any time. Unless previously terminated, the 2006 Plan will expire in February 2016. Any option granted under a plan will continue until the option expiration date, notwithstanding earlier termination of the plan under which the option was granted.
	In 2005, the Company began awarding nonvested share-awards under the existing share-based compensation plans. These nonvested share-awards vest in equal annual installments on each of the first four or five annual anniversaries of the award date, unless the person to whom the award was made is not then employed by Mobile Mini (or one of its subsidiaries). In 2013, the Company awarded certain of its officers performance based stock options. The Company did not grant performance based shares in 2012. If employment terminates, the shares are forfeited by the former employee.
	401(k) and Retirement Plans
	In 1995, the Company established a contributory retirement plan in the U.S., the 401(k) Plan, covering eligible employees. The 401(k) Plan is designed to provide tax-deferred retirement benefits to employees in accordance with the provisions of Section 401(k) of the Internal Revenue Code.
	The 401(k) Plan provides that each participant may annually contribute a fixed amount or a percentage of his or her salary, not to exceed the statutory limit. Mobile Mini may make a qualified non-elective contribution in an amount it determines. Under the terms of the 401(k) Plan, Mobile Mini may also make discretionary profit sharing contributions. Profit sharing contributions are allocated among participants based on their annual compensation. Each participant has the right to direct the investment of their funds among certain named plans. Mobile Mini contributes 25% of its employees’ contributions up to an annual maximum of $1 thousand per employee. The Company has a Registered Retirement Savings Plan regulated by Canadian law, where the Company makes matching contributions to its Canadian employees.
	In the U.K., the Company’s employees are covered by one of two separate defined contribution programs. The employees become eligible to participate in the programs once any initial employment probationary period is completed. The plans are designed as retirement benefit programs into that which the Company pays a contribution of either 5% or 7% of the employees’ annual salary into the plan. Depending on the plan, employees contribute either 0% or 2.5% of their annual salary into the plan and have the right to make further contributions if they so elect. The participants have the right to direct the investment of their funds among certain named plans. Annual charges are deducted from each employee’s fund to cover the administrative costs of these programs.
	In The Netherlands, the Company’s employees were covered by a defined contribution program. All employees became eligible after one month of employment. The Company contributed between 3.0% and 28.1% of the employees’ pensionable salary, depending on the employee’s age, and employees contributed 3.0% of their pensionable salary. The administrative costs for this plan were deducted by the administrative agent from the contributions and the investment earnings.
	Mobile Mini did not make any contributions to the retirement plan in the U.S. in 2011. The Company resumed making contributions to the U.S. retirement plan in 2012.
	Mobile Mini made contributions to the Canadian and U.K. plans of approximately $0.3 million in 2011 and to the U.S., Canadian and U.K. plans of approximately $0.4 million and $0.5 million in 2012 and 2013, respectively. The Company incurred approximately $30,500, $27,500 and $27,000 in 2011, 2012 and 2013, respectively, for administrative costs for these programs.

	Leases
	The Company leases its corporate offices and other properties and operating equipment from third parties under noncancelable operating leases. Rent expense under these agreements was approximately $18.5 million, $20.7 million and $21.2 million for the years ended December 31, 2011, 2012 and 2013, respectively.

	Future minimum lease payments under restructured non-cancelable operating leases as of December 31, 2013, are included in accrued liabilities in the Consolidated Balance Sheet. See Note 15 for a further discussion on restructuring related commitments.
	Insurance
	The Company maintains insurance coverage for its operations and employees with appropriate aggregate, per occurrence and deductible limits as the Company reasonably determines is necessary or prudent with current operations and historical experience. The majority of these coverages have large deductible programs which allow for potential improved cash flow benefits based on its loss control efforts.
	The Company’s 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. This plan allows for some cash flow benefits while guarantying a maximum premium liability. Actual results may vary from estimates based on the Company’s actual experience at the end of the plan policy periods based on the carrier’s loss predictions and its historical claims data.
	The Company’s worker’s compensation, auto and general liability insurance are purchased under large deductible programs. The Company’s current per incident deductibles are: worker’s compensation $250,000, auto $500,000 and general liability $100,000. The Company expenses the deductible portion of the individual claims. However, the Company generally does not know the full amount of its exposure to a deductible in connection with any particular claim during the fiscal period in which the claim is incurred and for which it must make an accrual for the deductible expense. The Company makes these accruals based on a combination of the claims development experience of its staff and its 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, the Company’s assumptions will change as its loss experience is developed. All of these factors have the potential for significantly impacting the amounts the Company has previously reserved in respect of anticipated deductible expenses and the Company may be required in the future to increase or decrease amounts previously accrued. Under the Company’s various insurance programs, it has collective reserves recorded in accrued liabilities of $5.1 million and $3.8 million at December 31, 2012 and 2013, respectively.
	As of December 31, 2013, in connection with the issuance of our insurance policies, Mobile Mini has provided its various insurance carriers approximately $7.4 million in letters of credit.
	General Litigation
	The Company is a party to routine claims incidental to its business. Most of these routine claims involve alleged damage to customers’ property while stored in units leased from Mobile Mini and damage alleged to have occurred during delivery and pick-up of containers. The Company carries insurance to protect it against loss from these types of claims, subject to deductibles under the policy. The Company does not believe that any of these incidental claims, individually or in the aggregate, is likely to have a material adverse effect on its business or results of operations.

	Treasury stock
	On November 6, 2013, the Board approved a share repurchase program authorizing up to $125.0 million of the Company’s outstanding shares of common stock to be repurchased. 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. As of December 31, 2013, no shares were repurchased under this program.
	In the fourth quarter of 2013, the Company withheld 9,530 shares of restricted stock awards to certain officers upon vesting of restricted stock to satisfy minimum tax withholding obligations.

	(14) Acquisitions
	The Company enters new markets in one of three ways: (i) a new fully staffed location start-up, (ii) through acquiring a business consisting of the portable storage assets and related leases of other companies, or (iii) by establishing new start-up locations that does have all the overhead associated with a fully-staffed location. An acquisition generally provides the Company with cash flow which enables the Company to immediately cover the overhead cost at a new location. On occasion, the Company also purchases portable storage businesses in areas where the Company has existing small locations either as part of multi-market acquisitions or in order to increase the Company’s operating margins at those locations.
	In the first quarter of 2012, Mobile Mini acquired the portable storage assets and assumed certain liabilities of a business based in Calgary, Canada, which became part of its Calgary location. This acquisition was effected pursuant to an asset purchase agreement. The Company did not acquire any businesses in 2013.
	The accompanying consolidated financial statements include the operations of the acquired business from the date of acquisition and were immaterial to the Company’s financial position in the aggregate. The acquisition was accounted for as a purchase of the business with the acquired assets and assumed liabilities recorded at their estimated fair values at the date of acquisition. The aggregate purchase price of the assets and operations acquired was $3.6 million.
	The fair value of the assets acquired and liabilities assumed has been allocated in the aggregate as follows at December 31, 2013 (in thousands):

	(16) Segment Reporting
	The Company has operations in North America and the U. K. The Company’s operating segments are similarly defined geographically. Discrete financial data on each of the Company’s products is not available and it would be impractical to collect and maintain financial data in such a manner. Financial results are aggregated into two reportable segments, North America and the U.K., based on quantitative thresholds. As discussed in Note 18 below, the Company’s Netherlands operation, which was previously presented as part of the Europe segment, is now presented within discontinued operation and prior period segment results have been recast. All of the Company’s locations operate in their local currency and, although the Company is exposed to foreign exchange rate fluctuation in other foreign markets where the Company leases and sells its products, the Company does not believe such exposure will have a significant impact on its results of operations.
	In managing the Company’s business, management focuses on growing leasing revenues, particularly in existing markets where it can take advantage of the operating leverage inherent in its business model, EBITDA and consolidated EPS.

	In the second quarter of 2013, the Company conducted field inspections of lease fleet units and other assets. A review was performed to determine the economic feasibility to repair certain assets. The analysis included the determination of fair market value of those assets using a cash flow analysis, less the cost of liquidation, and the current net carrying value. The Company’s senior management reviewed the analysis, the fair value of the assets, the current economy, along with present and projected utilization levels, and determined to place the assets for sale that were deemed to be either non-core to the Company’s leasing strategy or uneconomic to repair. The Company plans to sell the remainder of these assets by the end of the second quarter 2014. In connection with this action, the Company recorded an asset impairment charge of $40.2 million in the second quarter of 2013, of which $39.6 million was non-cash. Realized gains and losses resulting from the subsequent sale of these assets are recorded as a decrease or an increase to the original impairment charge in the statements of income and the proceeds associated with the disposal of these assets, excluding inventories, is recorded as investing activities in statements of cash flows.

Mobile Mini, its Operations and Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Fair Value Disclosures [Abstract]	'
Principles of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of Mobile Mini and its wholly owned subsidiaries. The Company does not have any subsidiaries in which it does not own 100% of the outstanding stock. All significant intercompany balances and transactions have been eliminated.
Discontinued Operation	'
	Discontinued Operation
	In December 2013, the Company sold the subsidiary comprising its Netherlands operation. The Netherlands operation is reflected as discontinued operation for all periods presented and all prior period amounts have been recast to reflect this transaction. See Note 18.
Revenue Recognition	'
	Revenue Recognition
	The Company recognizes revenue, including multiple element arrangements, in accordance with the provisions of applicable accounting guidance. The Company generates revenue from the leasing of portable storage containers and office units, as well as other services such as pickup and delivery. In most instances, the Company provides some of the above services under the terms of a single customer lease agreement. The Company also generates revenue from the sale of containers and office units.
	The Company’s lease arrangements typically include lease deliverables such as the lease of container or office unit and ancillary charges related to the leased container or office unit during the lease term. Arrangement consideration is allocated between lease deliverables and non-lease deliverables based on the relative estimated selling (leasing) price of each deliverable. Estimated selling (leasing) price of the lease deliverables is based on the price of those deliverables when sold separately (vendor-specific objective evidence). Because delivery and pick-up services are not sold separately by the Company, the estimated selling price of those deliverables is based on prices charged for similar services provided by other vendors (third party evidence of fair value).
	The arrangement consideration allocated to lease deliverables is accounted for pursuant to accounting guidance on leases. Such revenues from leases are billed in advance and recognized as earned, on a straight line basis over the lease period specified in the associated lease agreement. Lease agreement terms typically span several months or longer. Because the term of the agreements can extend across financial reporting periods, when leases are billed in advance, the Company defers recognition of revenue and records unearned leasing revenue at the end of reporting periods so that rental revenue is included in the appropriate period. Transportation revenue from container and mobile office delivery service is recognized on the delivery date and is recognized for pick-up service when the container or office unit is picked-up.
	The Company recognizes revenues from sales of containers and office units upon delivery when the risk of loss passes, the price is fixed and determinable and collectability is reasonably assured. The Company sells its products pursuant to sales contracts stating the fixed sales price with its customers.
Cost of Sales	'
	Cost of Sales
	Cost of sales in the Company’s consolidated statements of income includes only the costs for units it sells. Similar costs associated with the portable storage units that the Company leases are capitalized on its balance sheet under “Lease Fleet”.
Advertising Costs	'
	Advertising Costs
	All non-direct-response advertising costs are expensed as incurred. Yellow page advertising is capitalized when paid and amortized over the period in which the benefit is derived. At December 31, 2012 and 2013, prepaid advertising costs were approximately $0.6 million and $0.1 million, respectively. The amortization period of the prepaid balance never exceeds 12 months. Advertising expense was $9.5 million, $12.3 million and $5.8 million in 2011, 2012 and 2013, respectively.
Receivables and Allowance for Doubtful Accounts	'
	Receivables and Allowance for Doubtful Accounts
	Receivables primarily consist of amounts due from customers from the lease or sale of containers throughout the U.S., Canada and the U.K. Mobile Mini records an estimated provision for bad debts through a charge to operations in amounts of its estimated losses expected to be incurred in the collection of these accounts. The Company reviews the provision for adequacy monthly. The estimated losses are based on historical collection experience and evaluation of past-due account agings. Specific accounts are written off against the allowance when management determines the account is uncollectible. The Company requires a security deposit on most leased office units to cover the cost of damages or unpaid balances, if any.
Concentration of Credit Risk	'
	Concentration of Credit Risk
	Financial instruments which potentially expose the Company to concentrations of credit risk consist primarily of receivables. Concentration of credit risk with respect to receivables is limited due to the Company’s large number of customers spread over a broad geographic area in many industry sectors. No single customer accounts for more than 10.0% of our receivables at December 31, 2012 and 2013. Receivables related to its sales operations are generally secured by the product sold to the customer. Receivables related to its leasing operations are primarily small month-to-month amounts. The Company has the right to repossess leased 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 (FIFO) method) or market. Market is the lower of replacement cost or net realizable value. Inventories primarily consist of raw materials, supplies, work-in-process and finished goods, all related to the manufacturing, remanufacturing and maintenance, primarily for the Company’s lease fleet and its units held for sale. Raw materials principally consist of raw steel, wood, glass, paint, vinyl and other assembly components used in manufacturing and remanufacturing processes. Work-in-process primarily represents units being built that are either pre-sold or being built to add to its lease fleet upon completion. Finished portable storage units primarily represent ISO (International Organization for Standardization) containers held in inventory until the containers are either sold as is, remanufactured and sold, or units in the process of being remanufactured to be compliant with the Company’s lease fleet standards before transferring the units to its lease fleet. There is no certainty when the Company purchases the containers whether they will ultimately be sold, remanufactured and sold, or remanufactured and moved into its lease fleet. Units that are determined to go into the Company’s lease fleet undergo an extensive remanufacturing process that includes installing its proprietary locking system, signage, painting and sometimes its proprietary security doors.
Property, Plant and Equipment	'
	Property, Plant and Equipment
	Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is provided using the straight-line method over the assets’ estimated useful lives. Residual values are determined when the property is constructed or acquired and range up to 25%, depending on the nature of the asset. At the end of the second quarter of 2013, management reevaluated the Company’s depreciation policies and modified the useful life and residual values on forklifts, which became effective on July 1, 2013. Estimated residual values do not cause carrying values to exceed net realizable value. The Company’s depreciation expense related to property, plant and equipment for 2011, 2012 and 2013 was $11.7 million, $12.2 million and $12.7 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 leasing, selling and general expenses in the Consolidated Statements of Income.
Other Assets and Intangibles	'
	Other Assets and Intangibles
	Other assets and intangibles primarily represent deferred financing costs and intangible assets from acquisitions of $51.4 million at December 31, 2012 and $51.6 million at December 31, 2013, excluding accumulated amortization of $33.6 million at December 31, 2012 and $38.1 million at December 31, 2013. Deferred financing costs are amortized over the term of the agreement, and intangible assets are amortized on a straight-line basis, typically from five to 20 years, depending on its useful life. Intrinsic values assigned to customer relationships and trade names are amortized on an accelerated basis, typically over 15 years.
	Amortization expense for deferred financing costs was approximately $4.1 million, $3.2 million and $2.8 million in 2011, 2012 and 2013, respectively. In addition, in 2012, the Company wrote off $1.9 million of deferred financing costs related to the redemption of our 6.875% senior notes due 2015 and a portion of deferred financial costs related to our prior credit agreement. The annual amortization of deferred financing costs is expected to be $2.8 million in 2014, $2.8 million in 2015, $2.8 million in 2016, $0.9 million in 2017, $0.5 million in 2018 and $1.0 million thereafter.
	Amortization expense for all other intangibles was approximately $3.0 million, $2.2 million and $1.6 million in 2011, 2012 and 2013, respectively. Based on the carrying value at December 31, 2013, and assuming no subsequent impairment of the underlying assets, the annual amortization expense is expected to be $1.0 million in 2014, $0.7 million in 2015, $0.5 million in 2016, $0.2 million in 2017, $0.1 million in 2018 and $0.1 million thereafter.
Income Taxes	'
	Income Taxes
	Mobile Mini utilizes the liability method of accounting for income taxes where deferred taxes are determined based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect in the years in which the differences are expected to reverse. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. Income tax expense includes both taxes payable for the period and the change during the period in deferred tax assets and liabilities.
Earnings per Share	'
	Earnings per Share
	The Company’s preferred stock, if applicable, participates in distributions of earnings on the same basis as shares of common stock. As such, the Company adopted the accounting guidance for the standards regarding the computation of earnings per share (“EPS”) for securities other than common stock that contractually entitle the holder to participate in dividends and earnings of the Company. Earnings for the period are required to be allocated between the common and preferred stockholders based on their respective rights to receive dividends. Basic net income per share is then calculated by dividing income allocable to common stockholders by the weighted average number of common shares outstanding, net of shares subject to repurchase by the Company, during the period. The Company is not required to present basic and diluted net income per share for securities other than common stock. Accordingly, the following net income per share amounts only pertain to the Company’s common stock. The Company calculates diluted net income per share under the if-converted method unless the conversion of the preferred stock is anti-dilutive to basic net income per share. To the extent the inclusion of preferred stock is anti-dilutive, the Company calculates diluted net income per share under the two-class method. Potential common shares include restricted common stock, which is subject to risk of forfeiture and incremental shares of common stock issuable upon the exercise of stock options and upon the conversion of convertible preferred stock using the treasury stock method.
	Basic weighted average number of common shares outstanding does not include nonvested share-awards that had not vested of 1.2 million, 0.8 million and 0.5 million shares in 2011, 2012 and 2013, respectively.
Long Lived Assets	'
	Long Lived Assets
	Mobile Mini reviews long-lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of such assets may not be fully recoverable. 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. The Company did not recognize any impairment losses in the year ended December 31, 2012.
	In the second quarter of 2013, with a strategic focus on increasing return on capital and a move toward a rent-ready business model, the Company conducted an assessment of the lease fleet and rolling stock equipment. Management determined that certain of these units were either non-core to their leasing strategy or were uneconomic to repair. In connection with this evaluation, management determined to place the assets for sale, resulting in a non-cash impairment charge on long-lived assets of $37.6 million in the second quarter of 2013. (See Note 17).
Goodwill	'
	Goodwill
	Purchase prices of acquired businesses have been allocated to the assets and liabilities acquired based on the 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 were allocated to goodwill. Acquisitions of businesses under asset purchase agreements results in the goodwill relating to business acquisition being deductible for income tax purposes over 15 years even though goodwill is not amortized for financial reporting purposes.
	The Company evaluates goodwill periodically to determine whether events or circumstances have occurred that would indicate goodwill might be impaired. The Company originally had assigned its goodwill to each of its three reporting units (North America, the U.K. and The Netherlands). At December 31, 2013, only North America and the U.K. have goodwill subject to impairment testing. The Company performs an annual impairment test on goodwill at December 31. In addition, the Company will perform impairment tests during any reporting period in which events or changes in circumstances indicate that an impairment may have incurred. In assessing the fair value of the reporting units, the Company considers both the market and income approaches. 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 expenditure, tax payments and discount rates. Each approach was given equal weight in arriving at the fair value of the reporting unit. As of December 31, 2013, management assessed qualitative factors and determined it is more likely than not each of the Company’s reporting units 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 required.
	If the two step impairment test is necessary, the Company is required to determine the implied fair value of the goodwill and compare it to the carrying value of the goodwill. The Company would allocate the fair value of the reporting units 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. At December 31, 2013, $450.8 million of the goodwill relates to the North America reporting unit, and $68.4 million relates to the U.K. reporting unit.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The Company determines the estimated fair value of financial instruments using available market information and valuation methodologies. Considerable judgment is required in estimating fair values. Accordingly, the estimates may not be indicative of the amounts the Company could realize in current market exchanges.
	The carrying amounts of cash, receivables, accounts payable and accrued liabilities approximate fair values based on the liquidity of these financial instruments or based on their short-term nature. The carrying amounts of the Company’s borrowings under its credit facility, notes payable and capital leases approximate fair value. The fair values of the Company’s revolving credit facility, notes payable and capital leases are estimated using discounted cash flow analyses, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities, the fair value of the Company’s revolving credit facility debt, notes payable and capital leases at December 31, 2012 and 2013 approximated their respective book values and are considered Level 2 in the fair value hierarchy described in Note 2.
	The fair value of the Company’s $200.0 million aggregate principal amount of 7.875% senior notes due 2020 (the “2020 Notes” or the “Senior Notes”) is based on the latest sales price of such notes at the end of each period obtained from a third-party institution and is considered Level 2 in the fair value hierarchy described in Note 2, as there is not an active market for such notes.
Deferred Financing Costs	'
	Deferred Financing Costs
	Included in other assets and intangibles are deferred financing costs of approximately $13.6 million and $10.8 million, net of accumulated amortization of $14.5 million and $17.3 million, at December 31, 2012 and 2013, respectively. Costs of obtaining long-term financing, including the Company’s Credit Agreement (as defined below) (See Note 4), are amortized over the term of the related debt, using the straight-line method. Amortizing the deferred financing costs using the straight-line method approximates the effective interest method.
Derivatives	'
	Derivatives
	In the normal course of business, the Company’s operations are exposed to fluctuations in interest rates. The Company historically addressed 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.
	The Company’s primary interest rate risk exposure results from changes in short-term U.S. dollar interest rates. In an effort to manage interest rate exposures, the Company may enter into interest rate swap agreements that convert its floating rate debt to a fixed-rate, which are typically designated as cash flow hedges. Interest expense on the notional amounts under these agreements is accrued using the fixed rates identified in the swap agreements. At December 31, 2012 and 2013, the Company did not have any interest rate swap agreements.
Share-Based Compensation	'
	Share-Based Compensation
	At December 31, 2013, the Company had one active share-based employee compensation plan. There are two expired compensation plans, one of which still has outstanding options subject to exercise or termination. No additional options can be granted under the expired plans. Stock option awards under these plans are granted with an exercise price per share equal to the fair market value of the Company’s common stock on the date of grant. Each outstanding option must expire no more than ten years from the date it was granted, unless exercised or forfeited before the expiration date, and are granted with vesting periods ranging from three to four and a half years. The total value of the Company’s stock option awards is expensed over the related employee’s service period on a straight-line basis, or if subject to performance conditions, then the expense is recognized using the accelerated attribution method.
	The Company uses the modified prospective method and does not recognize a deferred tax asset for any excess tax benefit that has not been realized related to stock-based compensation deductions. The Company adopted the with-and-without approach with respect to the ordering of tax benefits realized. In the with-and-without approach, the excess tax benefit related to stock-based compensation deductions will be recognized in additional paid-in capital only if an incremental tax benefit would be realized after considering all other tax benefits presently available to us. Therefore, the Company’s net operating loss carryforward will offset current taxable income prior to the recognition of the tax benefit related to stock-based compensation deductions. In 2012 and 2013, there were $1.3 million and $4.2 million, respectively, of excess tax benefits related to stock-based compensation, which were not realized under this approach. Once the Company’s net operating loss carryforward is utilized, these aggregate excess tax benefits, totaling $14.2 million, may be recognized in additional paid-in capital.
	The Company also grants certain executive officers stock options and nonvested share-awards with vesting subject to performance conditions. Vesting of these grants is dependent upon the respective officers fulfilling the service period requirements as well as the Company achieving certain yearly adjusted EBITDA targets in each of the performance periods (three to four years) after the grant is awarded. EBITDA is defined as net income before discontinued operation, net of tax, interest expense, income taxes, depreciation and amortization and debt restructuring or extinguishment expense, including any write-off of deferred financing costs, and further adjusted for specific transactions, including non-cash share-based compensation expense, to arrive at adjusted EBITDA. For performance-based grants, the Company is required to assess the probability that such performance conditions will be met. If the likelihood of the performance conditions being met is deemed probable, the Company will recognize the expense using the accelerated attribution method. The accelerated attribution method could result in as much as 60% of the total value of the shares being recognized in the first year of the service period if the future performance-based targets are assessed as probable of being met. There was no adjustment in the past three years to reflect any underperformance for share-based compensation expense related to nonvested share-awards with vesting subject to performance conditions.
Foreign Currency Translation and Transactions	'
	Foreign Currency Translation and Transactions
	For Mobile Mini’s 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.
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. The most significant estimates included within the financial statements are the allowance for doubtful accounts, the estimated useful lives and residual values on the lease fleet and property, plant and equipment, goodwill and other asset impairments and certain accrued liabilities.
Fair Value Measurements, Policy	'
	The Company defines fair value as 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 that should be determined based on assumptions that market participants would use in pricing an asset or liability. As a basis for considering such assumptions, the Company adopted the suggested accounting guidance for the three levels of inputs that may be used to measure fair value:
		Level 1 —	Observable input 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.
Lease Fleet, Policy	'
	Mobile Mini’s lease fleet primarily consists of remanufactured, modified and manufactured steel storage containers, steel security offices, steel combination offices and wood mobile offices that are leased to customers under short-term operating lease agreements with varying terms. Depreciation is provided using the straight-line method over the units’ estimated useful life, after the date the Company put the unit in service, and are depreciated down to their estimated residual values. The Company’s depreciation policy on its steel units uses an estimated useful life of 30 years with an estimated residual value of 55%. Wood mobile office units are depreciated over 20 years down to a 50% residual value. Van trailers, which are a small part of the Company’s fleet, are depreciated over seven years to a 20% residual value. Van trailers and other non-core assets are typically only added to the fleet in connection with acquisitions of portable storage businesses. In the opinion of management, estimated residual values do not cause carrying values to exceed net realizable value. The Company continues to evaluate these depreciation policies as more information becomes available from other comparable sources and its own historical experience.
Income Tax Uncertainties, Policy	'
	Mobile Mini adopted a two-step approach to recognizing and measuring uncertain tax positions. 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	'
	The Company has operations in North America and the U. K. The Company’s operating segments are similarly defined geographically. Discrete financial data on each of the Company’s products is not available and it would be impractical to collect and maintain financial data in such a manner. Financial results are aggregated into two reportable segments, North America and the U.K., based on quantitative thresholds. As discussed in Note 18 below, the Company’s Netherlands operation, which was previously presented as part of the Europe segment, is now presented within discontinued operation and prior period segment results have been recast. All of the Company’s locations operate in their local currency and, although the Company is exposed to foreign exchange rate fluctuation in other foreign markets where the Company leases and sells its products, the Company does not believe such exposure will have a significant impact on its results of operations.
	In managing the Company’s business, management focuses on growing leasing revenues, particularly in existing markets where it can take advantage of the operating leverage inherent in its business model, EBITDA and consolidated EPS.

Organization Consolidation And Presentation Of Financial Statements [Abstract]	'
Condensed Consolidating Balance Sheets	'
	The following tables reflect the condensed consolidating financial information of the Company’s subsidiary guarantors of the Senior Notes and its non-guarantor subsidiaries. Separate financial statements of the subsidiary guarantors are not presented because the guarantee by each 100% owned subsidiary guarantor is full and unconditional, joint and several, subject to customer exceptions, and management has determined that such information is not material to investors. On December 31, 2012, the assets and liabilities of our Toronto, Canada location, which was part of the U.S. guarantor Company, were transferred to our Canadian subsidiary, Mobile Mini Canada ULC, which is a non-guarantor subsidiary of the Senior Notes.
