Summary of Significant Accounting Policies	'
	NOTE 1.	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	Organization
	McGrath RentCorp and its wholly-owned subsidiaries (the “Company”) is a California corporation organized in 1979. The Company is a diversified business to business rental company with three rental products; relocatable modular buildings, electronic test equipment and liquid and solid containment tanks and boxes. Although the Company’s primary emphasis is on equipment rentals, sales of equipment occur in the normal course of business. The Company is comprised of four business segments: its modular building division (“Mobile Modular”), its electronic test equipment division (“TRS-RenTelco”), its containment solutions for the storage of hazardous and non-hazardous liquids and solids division (“Adler Tanks”) and its classroom manufacturing division selling modular classrooms in California (“Enviroplex”).
	Principles of Consolidation
	The consolidated financial statements include the accounts of McGrath RentCorp and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
	Revenue Recognition
	Rental revenue from operating leases is recognized on a straight-line basis over the term of the lease. Rental billings for periods extending beyond period end are recorded as deferred income and are recognized when earned. Rental related services revenue is primarily associated with relocatable modular building and liquid and solid containment tanks and boxes leases. For modular building leases, rental related services revenue consists of billings to customers for modifications, delivery, installation, additional site-related work, and dismantle and return delivery. For modular building leases, revenue related to delivery, installation, dismantle and return delivery are an integral part of the negotiated lease agreement with customers and are recognized on a straight-line basis over the term of the lease. For liquid and solid containment solutions, rental related services revenue consists of billings for delivery, removal and cleaning of the tanks and boxes. These revenues are recognized in the period performed.
	Sales revenue is recognized upon delivery and installation of the equipment to customers. Certain leases are accounted for as sales-type leases. For these leases, sales revenue and the related accounts receivable are recognized upon delivery and installation of the equipment and the unearned interest is recognized over the lease term on a basis which results in a constant rate of return on the unrecovered lease investment.
	Other revenue is recognized when earned and primarily includes interest income on sales-type leases, rental income on facility rentals and certain logistics services.
	Sales taxes charged to customers are reported on a net basis and are excluded from revenues and expenses.
	Depreciation of Rental Equipment
	Rental equipment is depreciated on a straight-line basis for financial reporting purposes and on an accelerated basis for income tax purposes. The costs of major refurbishment of relocatable modular buildings and portable storage containers are capitalized to the extent the refurbishment significantly adds value to, or extends the life of the equipment. Maintenance and repairs are expensed as incurred.
	The estimated useful lives and residual values of the Company’s rental equipment used for financial reporting purposes are as follows:
	Relocatable modular buildings		18 years, 50% residual value
	Relocatable modular accessories		3 to 18 years, no residual value
	Portable storage containers		25 years, 62.5% residual value
	Electronic test equipment and accessories		1 to 8 years, no residual value
	Liquid and solid containment tanks and boxes and accessories		10 to 20 years, no residual value
	Costs of Rental Related Services
	Costs of rental related services are primarily associated with relocatable modular building leases and liquid and solid containment tank and boxes. Modular building leases consist of costs for services to be provided under the negotiated lease agreement for delivery, installation, modifications, skirting, additional site-related work, and dismantle and return delivery. Costs related to these services are recognized on a straight-line basis over the term of the lease. Costs of rental related services associated with liquid and solid containment solutions consists of costs of delivery, removal and cleaning of the tanks and boxes. These costs are recognized in the period the service is performed.
	Impairment of Long-Lived Assets
	The Company evaluates the carrying value of rental equipment and identifiable definite lived intangible assets for impairment whenever events or circumstances have occurred that would indicate the carrying amount may not be fully recoverable. A key element in determining the recoverability of long-lived assets is the Company’s outlook as to the future market conditions for its rental equipment. If the carrying amount is not fully recoverable, an impairment loss is recognized to reduce the carrying amount to fair value. The Company determines fair value based upon the condition of the rental equipment and the projected net cash flows from its rental and sale considering current market conditions. Goodwill and identifiable indefinite lived assets are evaluated for potential impairment annually or when circumstances indicate potential impairment may have occurred. Impairment losses, if any, are determined based upon the estimated fair value of the asset. There were no impairments of long-lived assets during the years ended December 31, 2013, 2012 and 2011.
	Other Direct Costs of Rental Operations
	Other direct costs of rental operations include direct labor, supplies, repairs, insurance, property taxes, license fees and certain modular lease costs charged to customers in the negotiated rental rate, which are recognized on a straight-line basis over the term of the lease.
	Cost of Sales
	Cost of sales in the Consolidated Statements of Income includes the carrying value of the equipment sold and all direct costs associated with the sale.
	Warranty Reserves
	Sales of new relocatable modular buildings, portable storage containers, electronic test equipment and related accessories and liquid and solid containment tanks and boxes not manufactured by the Company are typically covered by warranties provided by the manufacturer of the products sold. The Company typically provides limited 90-day warranties for certain sales of used rental equipment and one-year warranties on equipment manufactured by Enviroplex. Although the Company’s policy is to provide reserves for warranties when required for specific circumstances, the Company has not found it necessary to establish such reserves to date as warranty costs have not been significant.
	Property, Plant and Equipment
	Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is recognized on a straight-line basis for financial reporting purposes, and on an accelerated basis for income tax purposes. Depreciation expenses for property, plant and equipment is included in “Selling and Administrative Expenses” and “Rental Related Services” in the Consolidated Statements of Income. Maintenance and repairs are expensed as incurred.
	Property, plant and equipment consist of the following:
	(dollar amounts in thousands)		Estimated			December 31,
			Useful Life
			In Years			2013			2012
	Land			Indefinite		$	37,354		$	35,371
	Land Improvements			20 – 50			39,068			38,708
	Buildings			30			21,151			20,522
	Furniture, Office and Computer Equipment			3 – 10			30,761			26,496
	Machinery and Service Equipment			5 – 20			20,106			16,186
							148,440			137,283
	Less Accumulated Depreciation						(47,058	)		(39,301	)
							101,382			97,982
	Construction In Progress						3,805			3,049
							$105,187			$101,031
	Property, plant and equipment depreciation expense was $7.8 million, $7.8 million and $6.0 million for the years ended December 31, 2013, 2012 and 2011, respectively. Construction in progress at December 31, 2013 and 2012 consisted primarily of costs related to acquisition of land and land improvements.
	Capitalized Software Costs
	The Company capitalizes certain development costs incurred in connection with its internal use software. Costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, direct internal and external costs are capitalized until the software is substantially complete and ready for its intended use. These costs generally include external direct costs of materials and services consumed in the project and internal costs, such as payroll and benefits of those employees directly associated with the development of the software. Maintenance and training costs are expensed as incurred. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Capitalized software costs are included in property, plant and equipment. The Company capitalized $3.5 million and $0.9 million in internal use software during the years ended December 31, 2013 and 2012, respectively.
	Advertising Costs
	Advertising costs are expensed as incurred. Total advertising expenses were $2.4 million, $2.5 million and $2.1 million for the years ended December 31, 2013, 2012 and 2011.
	Income Taxes
	Income taxes are accounted for using an asset and liability approach. Deferred tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities at the tax rates in effect when these differences are expected to reverse.
	Goodwill and Intangible Assets
	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 and other intangible assets. Goodwill and intangible assets consists primarily of intangible assets of $39.9 million from the 2008 acquisition of Adler Tanks. Intangible assets related to customer relationships are amortized over eleven years. At December 31, 2013 and 2012, goodwill and trade name intangible assets which have indefinite lives totaled $33.4 million.
	The Company assesses potential impairment of its goodwill and intangible assets when there is evidence that events or circumstances have occurred that would indicate the recovery of an asset’s carrying value is unlikely. The Company also assesses potential impairment of its goodwill and intangible assets on an annual basis regardless of whether there is evidence of impairment. If indicators of impairment were to be present in intangible assets used in operations and future discounted cash flows were not expected to be sufficient to recover the assets’ carrying amount, an impairment loss would be charged to expense in the period identified. The amount of an impairment loss would be recognized as the excess of the asset’s carrying value over its fair value. Factors the Company considers important, which may cause impairment include, among others, significant changes in the manner of use of the acquired asset, negative industry or economic trends, and significant underperformance relative to historical or projected operating results.
	The impairment review of the Company’s goodwill and indefinite lived assets is performed by first assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. In the first step, the fair value of the reporting unit is compared to its carrying value to determine if the goodwill and intangible assets are impaired. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, then goodwill and intangible assets are not impaired and no further testing is required. If the carrying value of the net assets assigned to the reporting unit were to exceed its fair value, then the second step is performed in order to determine the implied fair value of the reporting unit’s goodwill and intangible assets and an impairment loss is recorded for an amount equal to the difference between the implied fair value and the carrying value of the goodwill and intangible assets.
	The Company conducted its annual impairment analysis in the fourth quarter of its fiscal year. The impairment analysis did not result in an impairment charge for the fiscal years ended 2013, 2012 or 2011. Determining the fair value of a reporting unit is judgmental and involves the use of significant estimates and assumptions. The Company based its fair value estimates on assumptions that it believes are reasonable but are uncertain and subject to changes in market conditions.
	Earnings Per Share
	Basic earnings per share (“EPS”) is computed as net income divided by the weighted average number of shares of common stock outstanding for the period. Diluted EPS is computed assuming conversion of all potentially dilutive securities including the dilutive effects of stock options, unvested restricted stock awards and other potentially dilutive securities. The table below presents the weighted-average common stock used to calculate basic and diluted earnings per share:
	(in thousands)		Year Ended December 31,
			2013			2012			2011
	Weighted-average common stock for calculating basic earnings per share			25,433			24,759			24,349
	Effect of potentially dilutive securities from equity-based compensation			493			397			411
	Weighted-average common stock for calculating diluted earnings per share			25,926			25,156			24,760
The following securities were not included in the computation of diluted earnings per share as their effect would have been anti-dilutive:
(in thousands)		Year Ended December 31,
		2013			2012			2011
Options to purchase common stock			20			1,049			1,131
Accounts Receivable and Concentration of Credit Risk
The Company’s accounts receivable consist of amounts due from customers for rentals, sales, financed sales and unbilled amounts for the portion of modular building end-of-lease services earned, which were negotiated as part of the lease agreement. Unbilled receivables related to end-of-lease services, which consists of dismantle and return delivery of buildings, were $18.9 million at December 31, 2013 and $17.4 million at December 31, 2012. The Company sells primarily on 30-day terms, individually performs credit evaluation procedures on its customers on each transaction and will require security deposits from its customers when a significant credit risk is identified. The Company records an allowance for doubtful accounts in amounts equal to the estimated losses expected to be incurred in the collection of the accounts receivable. The estimated losses are based on historical collection experience in conjunction with an evaluation of the current status of the existing accounts. Customer accounts are written off against the allowance for doubtful accounts when an account is determined to be uncollectable. The allowance for doubtful accounts activity was as follows:
(in thousands)		2013			2012
Beginning Balance, January 1		$	3,000		$	1,500
Provision for doubtful accounts			2,144			4,263
Write-offs, net of recoveries			(3,137	)		(2,763	)
Ending Balance, December 31		$	2,007		$	3,000
Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of trade accounts receivable. From time to time, the Company maintains cash balances in excess of the Federal Deposits Insurance limits.

The Company believes that the carrying amounts for cash, accounts receivable, accounts payable and notes payable approximate their fair values except for fixed rate debt included in notes payable which has an estimated fair value of $104.6 million and $106.0 million compared to the recorded value of $100.0 million as of December 31, 2013 and 2012, respectively. The estimates of fair value of the Company’s fixed rate debt are based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities.
Foreign Currency Transactions and Translation
The Company’s Canadian subsidiary, TRS-RenTelco Inc., a British Columbia corporation (“TRS-Canada”), functions as a branch sales office for TRS-RenTelco in Canada. The functional currency for TRS-Canada is the U.S. Dollar. Foreign currency transaction gains and losses of TRS-Canada are reported in the results of operations in the period in which they occur.
The Company’s Indian subsidiary, TRS-RenTelco India Private Limited (“TRS-India”), functions as a rental and sales office for TRS-RenTelco in India. The functional currency for TRS-India is the Indian Rupee. All assets and liabilities of TRS-India 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.
Currently, the Company does not use derivative instruments to hedge its economic exposure with respect to assets, liabilities and firm commitments as the foreign currency transactions and risks to date have not been significant.
Share-Based Compensation
The Company measures and recognizes the compensation expense for all share-based awards made to employees and directors, including stock options and restricted stock units (“RSUs”), based upon estimated fair values. The fair value of stock options is estimated on the date of grant using the Black-Scholes option pricing model and for RSUs based upon the fair market value of the underlying shares of common stock as of the date of grant. The Company recognizes share-based compensation cost ratably on a straight-line basis over the requisite service period, which generally equals the vesting period. For performance-based RSUs, compensation costs are recognized when vesting conditions are met. In addition, the Company estimates the probable number of shares of common stock that will be earned and the corresponding compensation cost until the achievement of the performance goal is known. The Company records share-based compensation costs in Selling and Administrative Expenses in the Consolidated Statements of Income. The Company recognizes a benefit from share-based compensation in the Consolidated Statements of Shareholders’ Equity if an incremental tax benefit is realized. Further information regarding share-based compensation can be found in Note 5 –Benefit Plans.
Use of Estimates
The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions in determining reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during each period presented. Actual results could differ from those estimates. The most significant estimates included in the financial statements are the future cash flows and fair values used to determine the recoverability of the rental equipment and identifiable definite lived intangible assets carrying value, the various assets’ useful lives and residual values, and the allowance for doubtful accounts.
Reclassifications
In order to conform to current year presentation, certain amounts on the Consolidated Statements of Cash Flows were reclassified from Proceeds from the Exercise of Stock Options to Taxes Paid Related to Net Share Settlement of Stock Awards. This reclassification had no impact on net income, earnings per share or operating cash flows.
New Accounting Pronouncements
In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists.” (“ASU 2013-11”). ASU 2013-11 requires entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when settlement in this manner is available under the tax law. The Company does not anticipate that the adoption of this standard will have a material impact on its consolidated financial statements.

	Unsecured Revolving Lines of Credit
	In June 2012, the Company entered into an amended and restated credit agreement with a syndicate of banks (the “Amended Credit Facility”). The five-year facility matures on June 15, 2017 and replaced the Company’s prior $350.0 million unsecured revolving credit facility. The Amended Credit Facility provides for a $420.0 million unsecured revolving credit facility (which may be increased to $450.0 million with $30.0 million of additional commitments), which includes a $25.0 million sublimit for the issuance of standby letters of credit and a $10.0 million sublimit for swingline loans. Amounts outstanding under the Amended Credit Facility at December 31, 2013 and 2012 were $186.0 million and $202.0 million, respectively.
	In June 2012, the Company entered into a Credit Facility Letter Agreement and a Credit Line Note in favor of Union Bank, N.A., extending its line of credit facility related to its cash management services (“Sweep Service Facility”) and increasing the facility size from $5.0 million to $10.0 million. The Sweep Service Facility matures on the earlier of June 15, 2017, or the date the Company ceases to utilize Union Bank, N.A. for its cash management services. Amounts outstanding under the Sweep Service Facility at December 31, 2013 and 2012 were $4.0 million and zero, respectively.
	At December 31, 2013, under the Amended Credit Facility and Sweep Service Facility, the Company had unsecured lines of credit that permit it to borrow up to $430.0 million of which $190.0 million was outstanding, and had capacity to borrow up to an additional $240.0 million. The Amended Credit Facility contains financial covenants requiring the Company to not (all defined terms used below not otherwise defined herein have the meaning assigned to such terms in the Amended Credit Facility):
		•		Permit the Consolidated Fixed Charge Coverage Ratio as of the end of any fiscal quarter to be less than 2.50 to 1. At December 31, 2013, the actual ratio was 4.01 to 1.
		•		Permit the Consolidated Leverage Ratio at any time during any period of four consecutive fiscal quarters to be greater than 2.75 to 1. At December 31, 2013, the actual ratio was 1.81 to 1.
		•		Permit Tangible Net Worth as of the end of any fiscal quarter of the Company to be less than the sum of (i) $246,103,400 plus (ii) 25% of the Company’s Consolidated Net Income (as defined in the Amended Credit Facility) (but only if a positive number) for each fiscal quarter ended subsequent to December 31, 2011 plus (iii) 90% of the net cash proceeds from the issuance of the Company’s capital stock after December 31, 2011. At December 31, 2013, such sum was $284.8 million and the actual Tangible Net Worth of the Company was $362.7 million.
	Amounts borrowed under the Amended Credit Facility bear interest at the Company’s option at either: (i) LIBOR plus a defined margin, or (ii) the Agent bank’s prime rate (“base rate”) plus a margin. The applicable margin for each type of loan is measured based upon the Consolidated Leverage Ratio at the end of the prior fiscal quarter and ranges from 1.00% to 1.75% for LIBOR loans and 0% to 0.75% for base rate loans. In addition, the Company pays an unused commitment fee for the portion of the $420.0 million credit facility that is not used. These fees are based upon the Consolidated Leverage Ratio and range from 0.15% to 0.30%. As of December 31, 2013 and 2012, the applicable margins were 1.50% for LIBOR based loans, 0.50% for base rate loans and 0.25% for unused fees. Amounts borrowed under the Sweep Service Facility are based upon the Union Bank, N.A. base rate plus an applicable margin and an unused commitment fee for the portion of the $10.0 million facility not used. The applicable base rate margin and unused commitment fee rates for the Sweep Service Facility are the same as for the Amended Credit Facility. The following information relates to the lines of credit for each of the following periods:
	(dollar amounts in thousands)		Year Ended December 31,
			2013			2012
	Maximum amount outstanding		$	202,000		$	220,799

	Prime interest rate, end of period			3.25	%		3.25	%
	4.03% Senior Notes Due in 2018
	On April 21, 2011, the Company entered into a Note Purchase and Private Shelf Agreement (the “Note Purchase Agreement”) with Prudential Investment Management, Inc., The Prudential Insurance Company of America and Prudential Retirement Insurance and Annuity Company (collectively, the “Purchaser”), pursuant to which the Company agreed to sell an aggregate principal amount of $100 million of its 4.03% Series A Senior Notes (the “Senior Notes”) to the Purchaser. The Senior Notes are an unsecured obligation of the Company, due on April 21, 2018. Interest on these notes is due semi-annually in arrears and the principal is due in five equal annual installments, with the first payment due on April 21, 2014. In addition, the Note Purchase Agreement allows for the issuance and sale of additional senior notes to the Purchaser (the “Shelf Notes”) in the aggregate principal amount of $100 million, to mature no more than 12 years after the date of original issuance thereof, to have an average life of no more than 10 years and to bear interest on the unpaid balance. Among other restrictions, the Note Purchase Agreement, under which the Senior Notes were sold, contains financial covenants requiring the Company to not (all defined terms used below not otherwise defined herein have the meaning assigned to such terms in the Note Purchase Agreement):
		•		Permit the Consolidated Fixed Charge Coverage Ratio of EBITDA to fixed charges as of the end of any fiscal quarter to be less than 2.50 to 1. At December 31, 2013, the actual ratio was 4.01 to 1.
		•		Permit the Consolidated Leverage Ratio of funded debt to EBITDA at any time during any period of four consecutive quarters to be greater than 2.75 to 1. At December 31, 2013, the actual ratio was 1.81 to 1.
		•		Permit Tangible Net Worth, calculated as of the last day of each fiscal quarter, to be less than the sum of (i) $229.0 million, plus (ii) 25% of net income for such fiscal quarter subsequent to December 31, 2010, plus (iii) 90% of the net cash proceeds from the issuance of the Company’s capital stock after December 31, 2010. At December 31, 2013, such sum was $284.8 million and the actual Tangible Net Worth of the Company was $362.7 million.
	At December 31, 2013, the Company was in compliance with each of the aforementioned covenants. There are no anticipated trends that the Company is aware of that would indicate non-compliance with these covenants, though, significant deterioration in the Company’s financial performance could impact its ability to comply with these covenants.

	In 2013, 2012 and 2011 the Company obtained an excess tax benefit of $1.3 million, $1.0 million and 1.0 million, respectively, from the exercise of non-qualified stock options and early dispositions of stock obtained through the exercise of incentive stock options by employees. The tax benefit was recorded as common stock in conjunction with the proceeds received from the exercise of the stock options.
	As of December 31, 2012, the Company’s federal net operating losses for tax return purposes were $12.3 million, which were fully utilized during 2013. As of December 31, 2013, the Company had state and foreign tax credit carry forwards of $2.6 million, which will begin to expire in 2022, if not utilized.
	The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority. The Company evaluated all of its tax positions for which the statute of limitations remained open and determined there were no material unrecognized tax benefits as of December 31, 2013 and 2012. In addition, there have been no material changes in unrecognized benefits during 2013, 2012 and 2011.
	The Company is subject to income taxes in the U.S. federal jurisdiction, and various states and foreign jurisdictions. Tax regulations within each jurisdiction are subject to interpretation of the related tax laws and regulations and require the application of significant judgment. With few exceptions, the Company is no longer subject to U.S. federal, state and local, or non-U.S. income tax examinations by tax authorities for the years before 2009.
	Our income tax returns are subject to examination by federal, state and foreign tax authorities. There may be differing interpretations of tax laws and regulations, and as a result, disputes may arise with these tax authorities involving the timing and amount of deductions and allocation of income.
	The Company recognizes interest and penalties related to unrecognized tax benefits in the provision for income taxes for all periods presented. Such interest and penalties were not significant for the years ended December 31, 2013, 2012 and 2011.
	In September 2013, the U.S. Department of the Treasury and the Internal Revenue Service released final regulations regarding the deductibility and capitalization of expenditures related to tangible property. The final regulations are effective for taxable years beginning on or after January 1, 2014. We are currently assessing these regulations and their impact to our financial statements. We do not anticipate that these regulations will have a material impact on our consolidated financial position.

	Stock Plans
	The Company adopted the 2007 Stock Incentive Plan (the “2007 Plan”) effective June 6, 2007, under which 1,875,000 shares of common stock of the Company, plus the number of shares that remained available for grants of awards under the Company’s 1998 Stock Option Plan (the “1998 Plan”) and those shares that become available as a result of forfeiture, termination, or expiration of awards previously granted under the 1998 Plan, were reserved for the grant of awards to its employees, directors and consultants to acquire common stock of the Company. The 2007 Plan is a shareholder approved plan with the initial 1,875,000 share authorization increased by 815,000 shares in 2009 and 1,500,000 shares in 2012. The 2007 Plan provides for the grant of awards in the form of stock options, stock appreciation rights, restricted stock, RSUs, the vesting of which may be performance-based or service-based, and other rights and benefits. Each RSU issued reduces the number of shares of the Company’s common stock available for grant under the 2007 Plan by two shares. Options under the 2007 Plan are granted at an exercise price of not less than 100% of the fair market value of the Company’s common stock on the date of grant. The 2007 Plan replaced the Company’s 1998 Plan and the 2000 Long-Term Bonus Plan. There were no modifications to the 2007 Plan and no awards classified as liabilities in the year ended December 31, 2013.
	For the years ended December 31, 2013, 2012 and 2011, the share-based compensation expense was $3.7 million, $3.8 million and $5.2 million, respectively, before provision for income taxes. The Company recorded a tax benefit of approximately $1.4 million, $1.5 million and $2.0 million, respectively, related to the aforementioned share-based compensation expenses. There was no capitalized share-based compensation expense in the years ended December 31, 2013, 2012 and 2011. For the years ended December 31, 2013, 2012 and 2011, the share-based compensation expenses, net of taxes, reduced net income by $2.2 million, $2.4 million and $3.2 million, respectively, or $0.09, $0.09, and $0.13 per diluted share for each period, respectively.
	Stock Options
	As of December 31, 2013, a cumulative total of 6,617,400 shares subject to options have been granted with exercise prices ranging from $3.47 to $38.89. Of these, options have been exercised for the purchase of 3,498,741 shares, while options for 874,152 shares have been terminated, and options for 1,772,062 shares with exercise prices ranging from $15.29 to $38.89 remained outstanding under the stock plans. Most of these options vest over five years and expire seven and ten years after grant. To date, no options have been issued to any of the Company’s non-employee advisors. As of December 31, 2013, 1,576,452 shares remained available for issuance of awards under the stock plans.
	A summary of the Company’s option activity and related information for the three years ended December 31, 2013 is as follows:

	The intrinsic value of stock options at any point in time is calculated as the difference between the exercise price of the underlying awards and the quoted price of the Company’s common stock. The aggregate intrinsic value of options exercised and sold under the Company’s stock option plans was $14.1 million, $4.9 million and $4.2 million for the years ended December 31, 2013, 2012 and 2011, respectively, determined as of the date of option exercise. As of December 31, 2013, there was approximately $3.4 million of total unrecognized compensation cost related to unvested share-based compensation option arrangements granted under the Company’s stock plans, which is expected to be recognized over a weighted-average period of 1.7 years.
	The following table indicates the options outstanding and options exercisable by exercise price with the weighted-average remaining contractual life for the options outstanding and the weighted-average exercise price at December 31, 2013:

	The Company utilizes the Black-Scholes option-pricing model to estimate the fair value of share-based compensation at the date of grant, which requires the use of accounting judgment and financial estimates, including estimates of the expected term option holders will retain their vested stock options before exercising them, the estimated volatility of the Company’s stock price over the expected term and the expected number of options that will be forfeited prior to the completion of their vesting requirements. Application of alternative assumptions could produce significantly different estimates of the fair value of share-based compensation amounts recognized in the Consolidated Statements of Income.
	The fair value of each option granted was estimated on the date of grant using the Black-Scholes option-pricing model using the following weighted-average assumptions:
			Year Ended December 31,
			2013			2012			2011
	Expected term (in years)			5			5			5
	Expected volatility			50.3	%		52.1	%		51.6	%
	Expected dividend yields			3.3	%		3.2	%		3.4	%
	Risk-free interest rates			0.8	%		0.8	%		2	%
	The Company monitors option exercise behavior to determine the appropriate homogenous groups for estimation purposes. Currently, the Company’s option activity is separated into two categories: directors and employees. The expected term of the options represents the estimated period of time until exercised and is based on historical experience, giving consideration to the option terms, vesting schedules and expectations of future behavior. Expected stock volatility is based on historical stock price volatility of the Company and the risk-free interest rates are based on U.S. Treasury yields in effect on the date of the option grant for the estimated period the options will be outstanding. The expected dividend yield is based upon the current dividend annualized as a percentage of the grant exercise price.
	The weighted average grant date fair value per share was $9.87, $10.28 and $9.68 during the years ended December 31, 2013, 2012 and 2011, respectively.
	Restricted Stock Units (“RSUs”)
	The following table summarizes the activity of the Company’s RSUs, which includes service-based and performance-based awards, for the three years ended December 31, 2013:

Performance-based RSUs vest over five years, with 60% of the shares immediately vesting after three years when the performance has been determined to have been met and 20% of the remaining shares vesting annually at the anniversary of the performance determination date, subject to continuous employment of the participant. There were 212,550 performance-based RSUs expected to vest as of December 31, 2013. Service-based RSUs have been issued to the Company’s directors and generally vest over one to two years. There were 20,280 service-based RSUs expected to vest as of December 31, 2013. No forfeitures are currently expected.
Share-based compensation expense for RSUs for the year ended December 31, 2013, 2012 and 2011 was $2.0 million, $1.8 million and $2.6, respectively. As of December 31, 2013, the total unrecognized compensation expense related to unvested RSUs was $4.7 million and is expected to be recognized over a weighted-average period of 2.7 years.
Employee Stock Ownership and 401(k) Plans
On August 1, 2012 the Company amended and restated the Employee Stock Ownership Plan, the 401(k) Plans and the Enviroplex 401(k) Plans (“Plans”) to become the McGrath RentCorp Employee Stock Ownership and 401(k) Plan (the “KSOP”). In conjunction with this, the Plans’ assets totaling approximately $16.4 million in cash were concurrently transferred into the KSOP. The KSOP plan provides that each participant may annually contribute an elected percentage of his or her salary, not to exceed the statutory limit. The Company, at its discretion, may make matching contributions. Contributions are expensed in the year approved by the Board of Directors. Dividends on the Company’s stock held by the KSOP are treated as ordinary dividends and, in accordance with existing tax laws, are deducted by the Company in the year paid. For the year ended December 31, 2013 dividends deducted by the Company were $0.3 million, which resulted in a tax benefit of approximately $0.1 million in 2013.
At December 31, 2013, the KSOP held 339,406 shares, or less than 2% of the Company’s total common shares outstanding. These shares are included in basic and diluted earnings per share calculations.

	NOTE 7.	COMMITMENTS AND CONTINGENCIES
	The Company leases certain facilities under various operating leases. Most of the lease agreements provide the Company with the option of renewing its lease at the end of the lease term, at the fair rental value. In most cases, management expects that in the normal course of business, facility leases will be renewed or replaced by other leases. Minimum payments under these leases, exclusive of property taxes and insurance, are as follows:
	(in thousands)
	Year Ended December 31,

	2016			686
	2017			667
	2018			612
	Thereafter			—
			$	4,222
	Rent expense was $3.1 million, $3.1 million and $2.4 million in 2013, 2012 and 2011, respectively.
	The Company is involved in various lawsuits and routine claims arising out of the normal course of its business. The Company maintains insurance coverage for its operations and employees with appropriate aggregate, per occurrence and deductible limits as the Company reasonably determines necessary or prudent with current operations and historical experience. The major policies include coverage for property, general liability, auto, directors and officers, health, and workers’ compensation insurances. The Company records a provision for a liability when it believes that it is both probable that a liability has been incurred and the amount can be reasonably estimated. Significant judgment is required to determine both probability and the estimated amount. The Company reviews these provisions at least quarterly and adjusts these provisions to reflect the impact of negotiations, settlements, rulings, advice of legal counsel, and updated information. Litigation is inherently unpredictable and is subject to significant uncertainties, some of which are beyond the Company’s control. In the opinion of management, there was not at least a reasonable possibility that the ultimate amount of liability not covered by insurance, if any, under any pending litigation and claims, individually or in the aggregate, will have a material adverse effect on the financial position or operating results of the Company.

Segment Reporting	'
	NOTE 10.	SEGMENT REPORTING
	FASB guidelines establish annual and interim reporting standards for an enterprise’s operating segments and related disclosures about its products, services, geographic areas and major customers. In accordance with these guidelines the Company’s four reportable segments are Mobile Modular, TRS-RenTelco, Adler Tanks and Enviroplex. Management focuses on several key measures to evaluate and assess each segment’s performance including rental revenue growth, gross margin, and income before provision for income taxes. As separate corporate entities, Adler Tanks and Enviroplex revenues and expenses are separately maintained from Mobile Modular and TRS-RenTelco. Excluding interest expense, allocations of revenue and expense not directly associated with one of these segments are generally allocated to Mobile Modular, TRS-RenTelco and Adler Tanks, based on their pro-rata share of direct revenues. Interest expense is allocated amongst Mobile Modular, TRS-RenTelco and Adler Tanks based on their pro-rata share of average rental equipment at cost, goodwill, intangible assets, accounts receivable, deferred income and customer security deposits. The Company does not report total assets by business segment. Summarized financial information for the years ended December 31, 2013, 2012 and 2011, for the Company’s reportable segments is shown in the following tables:

	Dec. 31, 2013
Accounting Policies [Abstract]	'
Organization	'
	Organization
	McGrath RentCorp and its wholly-owned subsidiaries (the “Company”) is a California corporation organized in 1979. The Company is a diversified business to business rental company with three rental products; relocatable modular buildings, electronic test equipment and liquid and solid containment tanks and boxes. Although the Company’s primary emphasis is on equipment rentals, sales of equipment occur in the normal course of business. The Company is comprised of four business segments: its modular building division (“Mobile Modular”), its electronic test equipment division (“TRS-RenTelco”), its containment solutions for the storage of hazardous and non-hazardous liquids and solids division (“Adler Tanks”) and its classroom manufacturing division selling modular classrooms in California (“Enviroplex”).
Principles of Consolidation	'
	Principles of Consolidation
	The consolidated financial statements include the accounts of McGrath RentCorp and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation.
Revenue Recognition	'
	Revenue Recognition
	Rental revenue from operating leases is recognized on a straight-line basis over the term of the lease. Rental billings for periods extending beyond period end are recorded as deferred income and are recognized when earned. Rental related services revenue is primarily associated with relocatable modular building and liquid and solid containment tanks and boxes leases. For modular building leases, rental related services revenue consists of billings to customers for modifications, delivery, installation, additional site-related work, and dismantle and return delivery. For modular building leases, revenue related to delivery, installation, dismantle and return delivery are an integral part of the negotiated lease agreement with customers and are recognized on a straight-line basis over the term of the lease. For liquid and solid containment solutions, rental related services revenue consists of billings for delivery, removal and cleaning of the tanks and boxes. These revenues are recognized in the period performed.
	Sales revenue is recognized upon delivery and installation of the equipment to customers. Certain leases are accounted for as sales-type leases. For these leases, sales revenue and the related accounts receivable are recognized upon delivery and installation of the equipment and the unearned interest is recognized over the lease term on a basis which results in a constant rate of return on the unrecovered lease investment.
	Other revenue is recognized when earned and primarily includes interest income on sales-type leases, rental income on facility rentals and certain logistics services.
	Sales taxes charged to customers are reported on a net basis and are excluded from revenues and expenses.
Depreciation of Rental Equipment	'
	Depreciation of Rental Equipment
	Rental equipment is depreciated on a straight-line basis for financial reporting purposes and on an accelerated basis for income tax purposes. The costs of major refurbishment of relocatable modular buildings and portable storage containers are capitalized to the extent the refurbishment significantly adds value to, or extends the life of the equipment. Maintenance and repairs are expensed as incurred.
Costs of Rental Related Services	'
	Costs of Rental Related Services
	Costs of rental related services are primarily associated with relocatable modular building leases and liquid and solid containment tank and boxes. Modular building leases consist of costs for services to be provided under the negotiated lease agreement for delivery, installation, modifications, skirting, additional site-related work, and dismantle and return delivery. Costs related to these services are recognized on a straight-line basis over the term of the lease. Costs of rental related services associated with liquid and solid containment solutions consists of costs of delivery, removal and cleaning of the tanks and boxes. These costs are recognized in the period the service is performed.
Impairment of Long-Lived Assets	'
	Impairment of Long-Lived Assets
	The Company evaluates the carrying value of rental equipment and identifiable definite lived intangible assets for impairment whenever events or circumstances have occurred that would indicate the carrying amount may not be fully recoverable. A key element in determining the recoverability of long-lived assets is the Company’s outlook as to the future market conditions for its rental equipment. If the carrying amount is not fully recoverable, an impairment loss is recognized to reduce the carrying amount to fair value. The Company determines fair value based upon the condition of the rental equipment and the projected net cash flows from its rental and sale considering current market conditions. Goodwill and identifiable indefinite lived assets are evaluated for potential impairment annually or when circumstances indicate potential impairment may have occurred. Impairment losses, if any, are determined based upon the estimated fair value of the asset. There were no impairments of long-lived assets during the years ended December 31, 2013, 2012 and 2011.
Other Direct Costs of Rental Operations	'
	Other Direct Costs of Rental Operations
	Other direct costs of rental operations include direct labor, supplies, repairs, insurance, property taxes, license fees and certain modular lease costs charged to customers in the negotiated rental rate, which are recognized on a straight-line basis over the term of the lease.
Cost of Sales	'
	Cost of Sales
	Cost of sales in the Consolidated Statements of Income includes the carrying value of the equipment sold and all direct costs associated with the sale.
Warranty Reserves	'
	Warranty Reserves
	Sales of new relocatable modular buildings, portable storage containers, electronic test equipment and related accessories and liquid and solid containment tanks and boxes not manufactured by the Company are typically covered by warranties provided by the manufacturer of the products sold. The Company typically provides limited 90-day warranties for certain sales of used rental equipment and one-year warranties on equipment manufactured by Enviroplex. Although the Company’s policy is to provide reserves for warranties when required for specific circumstances, the Company has not found it necessary to establish such reserves to date as warranty costs have not been significant.
Property, Plant and Equipment	'
	Property, Plant and Equipment
	Property, plant and equipment are stated at cost, net of accumulated depreciation. Depreciation is recognized on a straight-line basis for financial reporting purposes, and on an accelerated basis for income tax purposes.

Maintenance and repairs are expensed as incurred.
	Property, plant and equipment depreciation expense was $7.8 million, $7.8 million and $6.0 million for the years ended December 31, 2013, 2012 and 2011, respectively. Construction in progress at December 31, 2013 and 2012 consisted primarily of costs related to acquisition of land and land improvements.
Capitalized Software Costs	'
	Capitalized Software Costs
	The Company capitalizes certain development costs incurred in connection with its internal use software. Costs incurred in the preliminary stages of development are expensed as incurred. Once an application has reached the development stage, direct internal and external costs are capitalized until the software is substantially complete and ready for its intended use. These costs generally include external direct costs of materials and services consumed in the project and internal costs, such as payroll and benefits of those employees directly associated with the development of the software. Maintenance and training costs are expensed as incurred. The Company also capitalizes costs related to specific upgrades and enhancements when it is probable the expenditures will result in additional functionality. Capitalized software costs are included in property, plant and equipment.

Income Taxes	'
	Income Taxes
	Income taxes are accounted for using an asset and liability approach. Deferred tax assets and liabilities are recorded based on the differences between the financial statement and tax bases of assets and liabilities at the tax rates in effect when these differences are expected to reverse.
Goodwill and Intangible Assets	'
	Goodwill and Intangible Assets
	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 and other intangible assets. Goodwill and intangible assets consists primarily of intangible assets of $39.9 million from the 2008 acquisition of Adler Tanks. Intangible assets related to customer relationships are amortized over eleven years. At December 31, 2013 and 2012, goodwill and trade name intangible assets which have indefinite lives totaled $33.4 million.
	The Company assesses potential impairment of its goodwill and intangible assets when there is evidence that events or circumstances have occurred that would indicate the recovery of an asset’s carrying value is unlikely. The Company also assesses potential impairment of its goodwill and intangible assets on an annual basis regardless of whether there is evidence of impairment. If indicators of impairment were to be present in intangible assets used in operations and future discounted cash flows were not expected to be sufficient to recover the assets’ carrying amount, an impairment loss would be charged to expense in the period identified. The amount of an impairment loss would be recognized as the excess of the asset’s carrying value over its fair value. Factors the Company considers important, which may cause impairment include, among others, significant changes in the manner of use of the acquired asset, negative industry or economic trends, and significant underperformance relative to historical or projected operating results.
	The impairment review of the Company’s goodwill and indefinite lived assets is performed by first assessing qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test. In the first step, the fair value of the reporting unit is compared to its carrying value to determine if the goodwill and intangible assets are impaired. If the fair value of the reporting unit exceeds the carrying value of the net assets assigned to that unit, then goodwill and intangible assets are not impaired and no further testing is required. If the carrying value of the net assets assigned to the reporting unit were to exceed its fair value, then the second step is performed in order to determine the implied fair value of the reporting unit’s goodwill and intangible assets and an impairment loss is recorded for an amount equal to the difference between the implied fair value and the carrying value of the goodwill and intangible assets.
	The Company conducted its annual impairment analysis in the fourth quarter of its fiscal year. The impairment analysis did not result in an impairment charge for the fiscal years ended 2013, 2012 or 2011. Determining the fair value of a reporting unit is judgmental and involves the use of significant estimates and assumptions. The Company based its fair value estimates on assumptions that it believes are reasonable but are uncertain and subject to changes in market conditions.
Earnings Per Share	'
	Earnings Per Share
	Basic earnings per share (“EPS”) is computed as net income divided by the weighted average number of shares of common stock outstanding for the period. Diluted EPS is computed assuming conversion of all potentially dilutive securities including the dilutive effects of stock options, unvested restricted stock awards and other potentially dilutive securities.
Accounts Receivable and Concentration of Credit Risk	'
	Accounts Receivable and Concentration of Credit Risk
	The Company’s accounts receivable consist of amounts due from customers for rentals, sales, financed sales and unbilled amounts for the portion of modular building end-of-lease services earned, which were negotiated as part of the lease agreement. Unbilled receivables related to end-of-lease services, which consists of dismantle and return delivery of buildings, were $18.9 million at December 31, 2013 and $17.4 million at December 31, 2012. The Company sells primarily on 30-day terms, individually performs credit evaluation procedures on its customers on each transaction and will require security deposits from its customers when a significant credit risk is identified. The Company records an allowance for doubtful accounts in amounts equal to the estimated losses expected to be incurred in the collection of the accounts receivable. The estimated losses are based on historical collection experience in conjunction with an evaluation of the current status of the existing accounts. Customer accounts are written off against the allowance for doubtful accounts when an account is determined to be uncollectable.
	Financial instruments that potentially subject the Company to concentration of credit risk consist primarily of trade accounts receivable. From time to time, the Company maintains cash balances in excess of the Federal Deposits Insurance limits.
Fair Value of Financial Instruments	'
	Fair Value of Financial Instruments
	The Company believes that the carrying amounts for cash, accounts receivable, accounts payable and notes payable approximate their fair values except for fixed rate debt included in notes payable which has an estimated fair value of $104.6 million and $106.0 million compared to the recorded value of $100.0 million as of December 31, 2013 and 2012, respectively. The estimates of fair value of the Company’s fixed rate debt are based on the borrowing rates currently available to the Company for bank loans with similar terms and average maturities.
Foreign Currency Transactions and Translation	'
	Foreign Currency Transactions and Translation
	The Company’s Canadian subsidiary, TRS-RenTelco Inc., a British Columbia corporation (“TRS-Canada”), functions as a branch sales office for TRS-RenTelco in Canada. The functional currency for TRS-Canada is the U.S. Dollar. Foreign currency transaction gains and losses of TRS-Canada are reported in the results of operations in the period in which they occur.
	The Company’s Indian subsidiary, TRS-RenTelco India Private Limited (“TRS-India”), functions as a rental and sales office for TRS-RenTelco in India. The functional currency for TRS-India is the Indian Rupee. All assets and liabilities of TRS-India 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.
	Currently, the Company does not use derivative instruments to hedge its economic exposure with respect to assets, liabilities and firm commitments as the foreign currency transactions and risks to date have not been significant.
Share-Based Compensation	'
	Share-Based Compensation
	The Company measures and recognizes the compensation expense for all share-based awards made to employees and directors, including stock options and restricted stock units (“RSUs”), based upon estimated fair values. The fair value of stock options is estimated on the date of grant using the Black-Scholes option pricing model and for RSUs based upon the fair market value of the underlying shares of common stock as of the date of grant. The Company recognizes share-based compensation cost ratably on a straight-line basis over the requisite service period, which generally equals the vesting period. For performance-based RSUs, compensation costs are recognized when vesting conditions are met. In addition, the Company estimates the probable number of shares of common stock that will be earned and the corresponding compensation cost until the achievement of the performance goal is known. The Company records share-based compensation costs in Selling and Administrative Expenses in the Consolidated Statements of Income. The Company recognizes a benefit from share-based compensation in the Consolidated Statements of Shareholders’ Equity if an incremental tax benefit is realized. Further information regarding share-based compensation can be found in Note 5 –Benefit Plans.
Use of Estimates	'
	Use of Estimates
	The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions in determining reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during each period presented. Actual results could differ from those estimates. The most significant estimates included in the financial statements are the future cash flows and fair values used to determine the recoverability of the rental equipment and identifiable definite lived intangible assets carrying value, the various assets’ useful lives and residual values, and the allowance for doubtful accounts.
Reclassifications	'
	Reclassifications
	In order to conform to current year presentation, certain amounts on the Consolidated Statements of Cash Flows were reclassified from Proceeds from the Exercise of Stock Options to Taxes Paid Related to Net Share Settlement of Stock Awards. This reclassification had no impact on net income, earnings per share or operating cash flows.
New Accounting Pronouncements	'
	New Accounting Pronouncements
	In July 2013, the Financial Accounting Standards Board issued Accounting Standards Update No. 2013-11, “Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or Tax Credit Carryforward Exists.” (“ASU 2013-11”). ASU 2013-11 requires entities to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward when settlement in this manner is available under the tax law. The Company does not anticipate that the adoption of this standard will have a material impact on its consolidated financial statements.
Income Tax Position	'
	The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50 percent likelihood of being realized upon ultimate settlement with the relevant tax authority
Segment Reporting	'
	FASB guidelines establish annual and interim reporting standards for an enterprise’s operating segments and related disclosures about its products, services, geographic areas and major customers. In accordance with these guidelines the Company’s four reportable segments are Mobile Modular, TRS-RenTelco, Adler Tanks and Enviroplex. Management focuses on several key measures to evaluate and assess each segment’s performance including rental revenue growth, gross margin, and income before provision for income taxes. As separate corporate entities, Adler Tanks and Enviroplex revenues and expenses are separately maintained from Mobile Modular and TRS-RenTelco. Excluding interest expense, allocations of revenue and expense not directly associated with one of these segments are generally allocated to Mobile Modular, TRS-RenTelco and Adler Tanks, based on their pro-rata share of direct revenues. Interest expense is allocated amongst Mobile Modular, TRS-RenTelco and Adler Tanks based on their pro-rata share of average rental equipment at cost, goodwill, intangible assets, accounts receivable, deferred income and customer security deposits. The Company does not report total assets by business segment.

Debt instrument description of variable rate basis

'

'

'

'

'

'(i) LIBOR plus a defined margin, or (ii) the Agent bankbs prime rate (bbase rateb) plus a margin. The applicable margin for each type of loan is measured based upon the Consolidated Leverage Ratio at the end of the prior fiscal quarter and ranges from 1.00% to 1.75% for LIBOR loans and 0% to 0.75% for base rate loans. In addition, the Company pays an unused commitment fee for the portion of the $420.0 million credit facility that is not used. These fees are based upon the Consolidated Leverage Ratio and range from 0.15% to 0.30%. As of December 31, 2013 and 2012, the applicable margins were 1.50% for LIBOR based loans, 0.50% for base rate loans and 0.25% for unused fees. Amounts borrowed under the Sweep Service Facility are based upon the Union Bank, N.A. base rate plus an applicable margin and an unused commitment fee for the portion of the $10.0 million facility not used.
