	Organization and Nature of Business
	Chambers Street Properties (NYSE: CSG) is a self-administered real estate investment trust ("REIT") that focuses on acquiring, owning and managing net leased industrial and office properties leased to creditworthy tenants. We were formed under the laws of the state of Maryland on March 30, 2004, and have elected to be taxed as a REIT under sections 856 through 860 of the Internal Revenue Code of 1986 (the "Internal Revenue Code") beginning with the taxable period ended December 31, 2004.
	We operate in an umbrella partnership REIT structure in which our operating partnership, CSP Operating Partnership, LP ("CSP OP"), indirectly owns substantially all of the properties acquired on our behalf. CSP OP was formed in Delaware on March 30, 2004, and we are the 100% owner and sole general partner. For each interest in our common shares of beneficial interest $0.01 par value (the "common shares"), that we issue, an equal interest in the limited partnership units of CSP OP is issued to us in exchange for the cash proceeds from the issuance of the interest in our common shares. As of September 30, 2014, we owned 100% of the limited partnership units of CSP OP directly or indirectly through a wholly-owned taxable REIT subsidiary.
	On May 21, 2013, we listed our common shares on the New York Stock Exchange (the "NYSE") under the symbol "CSG" (our "Listing") and concurrently commenced a modified "Dutch Auction" tender offer to purchase up to $125.0 million in value of the common shares (the "Tender Offer") from our shareholders. As a result of the Tender Offer, on June 26, 2013, we accepted for purchase 12,376,237 common shares at a purchase price of $10.10 per share, for an aggregate cost of approximately $125.0 million, excluding fees and expenses relating to the Tender Offer. As of September 30, 2014, we had 236,924,176 common shares issued and outstanding.
	As of September 30, 2014, we owned, on a consolidated basis, 100 industrial (primarily warehouse/distribution) and office properties located in 19 U.S. states (Arizona, California, Colorado, Florida, Georgia, Illinois, Indiana, Kansas, Kentucky, Maryland, Massachusetts, Minnesota, New Jersey, North Carolina, Ohio, Pennsylvania, South Carolina, Texas and Virginia) and in the United Kingdom, encompassing approximately 23.5 million rentable square feet. Our consolidated properties were approximately 96.1% leased (based upon rentable square feet) as of September 30, 2014. As of September 30, 2014, 76 of our consolidated properties were net leased to single tenants, which encompassed approximately 19.2 million rentable square feet.
	We had ownership interests in four unconsolidated entities that, as of September 30, 2014, owned interests in 32 properties. Excluding those properties owned through our investment in CB Richard Ellis Strategic Partners Asia II-A, L.P. ("CBRE Strategic Partners Asia"), we owned, on an unconsolidated basis, 29 industrial (primarily warehouse/distribution) and office properties located in eight U.S. states (Arizona, Florida, Illinois, Indiana, North Carolina, Ohio, Tennessee and Texas) and three countries in Europe (France, Germany and the United Kingdom), encompassing approximately 12.8 million rentable square feet. Our unconsolidated properties were approximately 99.5% leased (based upon rentable square feet) as of September 30, 2014. As of September 30, 2014, 20 of our unconsolidated properties were net leased to single tenants, which encompassed approximately 11.5 million rentable square feet.
	Unless the context otherwise requires or indicates, references to the "Company," "we," "our" and "us" refer to the activities of and the assets and liabilities of the business and operations of Chambers Street Properties and its subsidiaries. References to unconsolidated properties include properties owned through unconsolidated joint ventures and do not include properties owned by CBRE Strategic Partners Asia. See Note 4 "Investments in Unconsolidated Entities."

	Basis of Presentation and Summary of Significant Accounting Policies
	Basis of Presentation and Principles of Consolidation
	The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") and reflect the accounts of the Company, CSP OP and its consolidated subsidiaries. The Company consolidates its wholly-owned properties and joint ventures it controls through either 1) voting rights or similar rights or 2) by means other than voting rights if the Company is deemed to be the primary beneficiary of a variable interest entity. All intercompany accounts and transactions are eliminated in consolidation.
	Certain information and footnotes required for annual financial statement presentation have been condensed or excluded pursuant to Securities and Exchange Commission (the "SEC") rules and regulations. Accordingly, our interim financial statements do not include all of the information and disclosures required under GAAP for complete financial statements. In the opinion of management, all adjustments of a normal recurring nature considered necessary in all material respects to present fairly our financial position, results of our operations and cash flows as of and for the three and nine months ended September 30, 2014 have been made. The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results of operations to be expected for the entire year. The condensed consolidated financial statements and notes thereto should be read in conjunction with our current Annual Report on Form 10-K, which contains the latest available audited consolidated financial statements and notes thereto, which are as of and for the year ended December 31, 2013.
	Use of Estimates
	The preparation of financial statements, in conformity with GAAP, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
	Segment Information
	Our chief operating decision-makers internally evaluate the operating performance and financial results of our portfolio based on Net Operating Income. We define "Net Operating Income" as: rental income, tenant reimbursements, and other property income less property and related expenses (operating and maintenance and real estate taxes) and excludes other non-property income and expenses, interest expense, depreciation and amortization, and corporate general and administrative expenses. During the first quarter of 2014, we reassessed our segment reporting and determined that the proper aggregation of our properties was by property type, Industrial Properties and Office Properties. Both of these operating segments meet the 10% quantitative reporting thresholds to be considered a reportable segment under GAAP and reflect the core operations of our business. Beginning with the reporting period ended March 31, 2014, we view our consolidated property operations as two reportable segments: Industrial Properties and Office Properties. In addition, we had one non-reportable segment, which was Retail Properties. However, during the third quarter ended September 30, 2014 we sold our last remaining retail property, therefore, eliminating the non-reportable segment from future reportable presentations. We have reclassified the prior period segment financial results to conform to the current year presentation.
	Revenue Recognition and Valuation of Receivables
	All leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the terms of the leases. The excess of rents recognized over amounts contractually due pursuant to the underlying leases is recorded as deferred rent. In connection with various leases, we have received irrevocable stand-by letters of credit totaling $14.8 million and $14.5 million as security for such leases at September 30, 2014 and December 31, 2013.
	Reimbursements from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes, insurance and other recoverable costs, are recognized as revenue in the period the expenses are incurred. Tenant reimbursements are recognized and presented on a gross basis, when we are the primary obligor with respect to incurring expenses and with respect to having the credit risk.
	Tenant receivables and deferred rent receivables are carried net of the allowances for uncollectible current tenant receivables and deferred rent. Management's determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, individual receivables, current economic conditions, and other relevant factors. The allowances are increased or decreased through the provision for bad debts. The allowance for uncollectible rent receivable was $57,000 and $24,000 as of September 30, 2014 and December 31, 2013, respectively.
	Translation of Non-U.S. Currency Amounts
	The financial statements and transactions of our United Kingdom real estate operation are recorded in their functional currency, namely the Great Britain Pound ("GBP") and are then translated into U.S. dollars ("USD").
	Assets and liabilities of this operation are denominated in the functional currency and are then translated at exchange rates in effect at the balance sheet date. Revenues and expenses are translated at the average exchange rate for the reporting period. Translation adjustments are reported in "Accumulated Other Comprehensive Income (Loss)," a component of Shareholders' Equity.
	The carrying value of our United Kingdom assets and liabilities fluctuate due to changes in the exchange rate between the USD and the GBP. The exchange rate of the USD to the GBP was $1.6213 and $1.6573 at September 30, 2014 and December 31, 2013, respectively. The profit and loss weighted average exchange rate of the USD to the GBP was approximately $1.6862 and $1.5301 for the three months ended September 30, 2014 and 2013, respectively; and approximately $1.6737 and $1.5449 for the nine months ended September 30, 2014 and 2013, respectively.
	The carrying value of our assets and liabilities held within our joint venture in Europe (the "European JV") fluctuate due to changes in the exchange rate between the USD and the Euro ("EUR"). The exchange rate of the USD to the EUR was $1.2631 and $1.3753 at September 30, 2014 and December 31, 2013. The profit and loss weighted average exchange rate of the USD to the EUR was approximately $1.3402 and $1.3175 for the three months ended September 30, 2014 and 2013, respectively; and approximately $1.3611 and $1.3146 for the nine months ended September 30, 2014 and 2013, respectively.
	Transition and Listing Expenses
	We incurred certain costs in connection with our transition from being an externally managed company to a self-managed company ("Transition Costs"). These Transition Costs consist of legal, consulting and other third-party service provider costs incurred by us in order to execute on our Board of Trustees' decision to become a self-managed company. The Transition Costs were primarily incurred during 2012, with the exception of $0.7 million incurred during 2013 as a final settlement of the Transition Services Agreement.
	We incurred certain costs in connection with our Listing and our Tender Offer in 2013. These listing expenses consisted of legal, investment banking, share-based compensation, consulting and other third-party service provider costs incurred by us in order to complete our Listing and Tender Offer. Listing costs totaling $12.0 million were incurred during the year ended December 31, 2013. Of the listing expenses incurred through December 31, 2013, $3.8 million was attributable to share-based compensation.
	Income Taxes
	We elected to be taxed as a REIT under the Internal Revenue Code commencing with our taxable year ended December 31, 2004. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement that we generally distribute at least 90% of our REIT taxable income (determined without regard to the dividends paid deduction and excluding net capital gain). It is our current intention to adhere to these requirements and maintain our REIT qualification. As a REIT, we generally will not be subject to corporate level U.S. federal income tax on net income we distribute currently to our shareholders. If we fail to qualify as a REIT in any taxable year, then we will be subject to U.S. federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if we qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income and property and to U.S. federal income and excise taxes on our undistributed taxable income, if any.
	ASC 740-10 Income Taxes requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. We did not have a liability for any unrecognized benefits as of September 30, 2014. The tax years from 2010 through 2013 remain open to examination by the taxing jurisdictions to which the Company is subject.
	Included as a component of our tax provision, we have incurred income and other taxes (franchise, local and state government and international) related to our continuing operations in the amount of $140,000 and $54,000 during the three months ended September 30, 2014 and 2013, respectively; and $579,000 and $274,000 during the nine months ended September 30, 2014 and 2013, respectively. The United Kingdom taxes real property operating results at a statutory rate of 20%. The United Kingdom taxable losses to date have generated a deferred tax asset of approximately $0.6 million consisting of these net operating loss carryforwards. We have provided for a full valuation allowance of $0.6 million as of September 30, 2014 on deferred tax assets because it is not likely that future operating profits in the United Kingdom would be sufficient to absorb the net operating losses.
	New Accounting Standards
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which requires only disposals representing a strategic shift in operations (i.e., a disposal of a major geographic area, a major line of business, or a major equity method investment) to be presented as discontinued operations. The standard also requires expanded disclosures about discontinued operations and is intended to provide financial statement users with information about the ongoing trends in a company's results from continuing operations. ASU No. 2014-08 is effective in the first quarter of 2015 for public entities with calendar year ends. However, companies are permitted to early adopt the standard, beginning in the first quarter of 2014, but only for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. We early adopted this standard in the first quarter of 2014 and the adoption did not have a material effect on our financial condition, results of operations, or disclosures.
	In May 2014, the FASB and IASB issued their final standard on revenue from contracts with customers. The standard, issued by the FASB as ASU 2014-09, outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including the guidance on real estate derecognition for most transactions. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance in ASU 2014-09. For public entities, the ASU is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016. Early application is not permitted. We are assessing the impact of this guidance on our consolidated financial statements and notes to our consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The ASU clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Therefore, an entity would not record compensation expense (measured as of the grant date without taking into account the effect of the performance target) related to an award for which transfer to the employee is contingent on the entity’s satisfaction of a performance target until it becomes probable that the performance target will be met. ASU No. 2014-12 will be effective for all entities for reporting periods (including interim periods) beginning after December 15, 2015, and early adoption is permitted. ASU 2014-12 may be adopted either prospectively for share-based payment awards granted or modified on or after the effective date, or retrospectively, using a modified retrospective approach. The modified retrospective approach would apply to share-based payment awards outstanding as of the beginning of the earliest annual period presented in the financial statements on adoption, and to all new or modified awards thereafter. The adoption of this guidance is not anticipated to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The ASU provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. The ASU applies to all entities and is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The adoption of this guidance is not anticipated to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.

Derivative Instruments and Hedging Activities Disclosure [Abstract]	'
Risk Management and Use of Financial Instruments	'
	Risk Management and Use of Financial Instruments
	Risk Management
	In the course of our ongoing business operations, we encounter economic risk. There are three main components of economic risk: interest rate risk, credit risk and market risk. We are subject to interest rate risk on our interest-bearing liabilities. Credit risk is primarily the risk of inability or unwillingness of tenants to make contractually required payments and of counterparties on derivatives contracts to fulfill their obligations. Market risk is the risk of declines in the value of our properties due to changes in rental rates, interest rates, supply and demand of similar products and other market factors affecting the valuation of properties.
	Derivative Financial Instruments
	We utilize interest rate swaps to mitigate the effects of interest rate fluctuations on our variable-rate loans. Our strategy is to use a swap to convert the floating-rate borrowing (usually a secured note payable or an unsecured term loan facility) where LIBOR is consistently applied into a fixed-rate obligation with the only variable piece remaining is the spread between different reset dates when/if the swap and debt are not lined up. We generally enter into an interest rate swap agreement concurrently with the origination of the variable-rate loan for an equivalent principal amount for a period covering the term of the loan, which effectively converts our variable-rate debt to a fixed-rate loan. Our use of derivative instruments, including swaps, is limited by policy to hedging or mitigating commercial risk and we do not use derivative instruments for speculative, trading or investment purposes.
	The following table sets forth the terms of our interest rate swaps at September 30, 2014 and December 31, 2013 (amounts in thousands):

At September 30, 2014, the Company expects that the hedged forecasted transactions, for each of the outstanding qualifying cash flow hedging relationships, remains probable of occurring. During the next twelve months we anticipate reclassifying $8.0 million of amounts currently recorded in accumulated other comprehensive income to earnings.
Concentration of Credit Risk
Our credit risk relates primarily to cash, restricted cash, and interest rate swap agreements. Cash accounts at each U.S. institution are insured by the Federal Deposit Insurance Corporation up to $250,000 through December 31, 2014.
We have not experienced any losses to date on our invested cash and restricted cash. The interest rate swap agreements create credit risk. Credit risk arises from the potential failure of counterparties to perform in accordance with the terms of their contracts. Our risk management policies define parameters of acceptable market risk and limit exposure to credit risk. Credit exposure resulting from derivative financial instruments is represented by their fair value amounts, increased by an estimate of potential adverse position exposure arising from changes over time in interest rates, maturities, and other relevant factors. We do not anticipate nonperformance by any of our counterparties.
Our consolidated properties are located throughout the United States and in the United Kingdom. The ability of the tenants to honor the terms of their respective leases is dependent upon the economic, regulatory, and social factors affecting the communities in which the tenants operate. In addition, we do not have any tenant whose rents exceeds 10% of our total rental revenue.

	Related Party Transactions
	Prior to July 1, 2012, all of our business activities were managed by the former investment advisor pursuant to the fourth amended and restated advisory agreement ("Fourth Amended Advisory Agreement"), which terminated according to its terms on June 30, 2012. Effective July 1, 2012, we entered into the Transitional Services Agreement with the former investment advisor pursuant to which the former investment advisor would provide certain consulting related services to us at the direction of our officers and other personnel for a term which ended on April 30, 2013. As part of the Transitional Services Agreement, we paid $2.5 million on the effective date of the agreement to reimburse the former investment advisor for expenses incurred related to personnel costs. In addition, during 2013, we paid $0.7 million to the former investment advisor as a final settlement of the Transitional Services Agreement.
	Pursuant to the Transitional Services Agreement, for services provided to us in connection with the investment management of our assets, the former investment advisor was paid an investment management consulting fee payable in cash consisting of (i) a monthly fee equal to one-twelfth of 0.5% of the aggregate cost (before non-cash reserves and depreciation) of all real estate investments within our portfolio and (ii) a monthly fee equal to 5.0% of the aggregate monthly net operating income derived from all real estate investments within our portfolio, subject to certain adjustments. For services provided to us in connection with the acquisition of assets, the former investment advisor or its affiliates was paid acquisition fees up to 1.5% of (i) the contract purchase price of real estate investments acquired by us, or (ii) when we make an investment indirectly through another entity, such investment's pro rata share of the gross asset value of real estate investments held by that entity. The total of all acquisition consulting fees payable with respect to real estate investments did not exceed an amount equal to 6% of the contract purchase price (or 6% of funds advanced with respect to mortgages) provided, however, that a majority of the uninterested members of the Board of Trustees could approve amounts in excess of this limit.
	As required by the Transitional Services Agreement, we and the former investment advisor have agreed on a list of unacquired real estate investments for which the former investment advisor has performed certain acquisition related consulting services prior to the termination of the Transitional Service Agreement (a "Qualifying Property"). If any Qualifying Property is acquired by us within the nine months following the termination of the Transitional Services Agreement then we shall pay an acquisition consulting fee equal to 0.75% of (i) the contract purchase price of the real estate investments (including debt), or (ii) when we make an investment indirectly through another entity, such investment's pro rata share of the gross asset value of real estate investments held by that entity to the former investment advisor.
	During the nine months ended September 30, 2014, we acquired one Qualifying Property and paid the former investment advisor $0.2 million in acquisition consulting fees. There are no further Qualifying Properties under the Transitional Services Agreement and we do not anticipate paying the former investment advisor any further acquisition consulting fees.
	Previously, pursuant to the Fourth Amended Advisory Agreement and the Transitional Services Agreement, the former investment advisor and its affiliates performed services relating to property management, leasing, construction supervision and management, and brokerage services. The various fees paid to the former investment advisor are summarized in the table below for the three and nine months ended September 30, 2013 (in thousands):

	Equity Incentive Plan
	At our annual shareholders' meeting held on May 31, 2013, our shareholders approved the 2013 equity incentive plan. A description of the material terms of the 2013 equity incentive plan, as well as a copy of the 2013 equity incentive plan, were included in our definitive proxy statement on Schedule 14A filed with the SEC on April 12, 2013. Our key employees, directors, trustees, officers, advisors, consultants or other personnel of ours and our subsidiaries or other persons expected to provide significant services to us or our subsidiaries would be eligible to be granted incentive share options, non-qualified share options, share appreciation rights, restricted shares, restricted share units, dividend equivalent rights and other equity-based awards as contemplated in the 2013 equity incentive plan. As of September 30, 2014, there were 4,041,992 common shares available for grant under the 2013 equity incentive plan.
	On January 29, 2014, our Board's independent trustees, Messrs. Charles Black, Mark Brugger, James Francis, James Orphanides and Louis Salvatore, were awarded equity grants under the 2013 equity incentive plan on the following terms: (i) (x) Mr. Black's award was for 20,000 common shares, (y) Messrs. Orphanides and Salvatore each were awarded 5,000 common shares and (z) Messrs. Brugger and Francis each were awarded 1,550 common shares for a total of 33,100 and (ii) each award vested in its entirety, upon issuance.
	On February 26, 2014, the Company and Operating Partnership entered into an amendment to Martin A. Reid's employment agreement, effective as of January 1, 2013, increasing Mr. Reid's annual target Long Term Incentive Award to 90,000 restricted common shares of the Company.
	On March 15, 2014, a total of 401,875 restricted common shares were granted to our named executive officers (Messrs. Cuneo, Kianka and Reid) based on each executive's achievement of performance objectives during 2013, as determined at the discretion of our Compensation Committee. Additionally, 25 of our employees were granted 143,450 restricted common shares, in the aggregate, on March 15, 2014. One-third of the restricted shares granted to our named executive officers and employees will vest on each of the first three anniversaries of grant if the grantee is employed by the Company on such anniversary. Compensation expense is recognized on a straight-line basis over the service vesting period of three years. We recognized share-based compensation expense of $563,000 and $968,000 during the three and nine months ended September 30, 2014 as a result of granting the awards to our named executive officers and our employees.
	On July 31, 2014, the Compensation Committee of the Board of Trustees (the “Compensation Committee”) of the Company adopted and approved an incentive bonus plan, a form of restricted share award agreement, and a form of restricted share unit award agreement that may be used in connection with awards made pursuant to the 2013 equity incentive plan from time to time to the Company’s trustees, executive officers and other employees.
	The incentive bonus plan is intended to provide additional incentive for key employees of the Company to perform to the best of our abilities, to further the growth, development and financial success of the Company, and to enable us to attract and retain qualified and talented individuals. Restricted shares are awarded to grantees based on a time-based vesting formula. Restricted share units represent a contingent commitment of the Company to issue shares to a grantee based on certain performance-based goals determined by the Compensation Committee.
	Summary of Time-Based Restricted Common Shares
	A summary of our Time-Based Restricted Common Shares from January 1, 2014 through September 30, 2014 is presented below:

Fair Value Disclosures [Abstract]	'
Fair Value of Financial Instruments and Investments	'
	Fair Value of Financial Instruments and Investments
	We apply the three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: Level 1, defined as observable inputs such as quoted prices for identical financial instruments in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as instruments that have little to no pricing observability as of the reported date. These financial instruments do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation.
	As of September 30, 2014 and December 31, 2013, we held certain items that were required to be measured at fair value on a recurring basis. These included cash equivalents, interest rate swap derivative contracts and our equity method investment in CBRE Strategic Partners Asia. Cash equivalents consist of short-term, highly liquid, income-producing investments, all of which have original maturities of 90 days or less, including money market funds and U.S. Government obligations. Derivative instruments are related to our economic hedging activities with respect to interest rates.
	The fair values of the interest rate swap derivative agreements are estimated with the assistance of a third-party valuation specialist using the market standard methodology of discounting the future expected cash payments and receipts on the pay and receive legs of the interest rate swap agreements that swap the estimated variable rate mortgage note payment stream for a fixed rate receive payment stream over the period of the loan. The variable interest rates used in the calculation of projected receipts on the interest rate swap agreements are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. We incorporate credit valuation adjustments to appropriately reflect both our own nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements (where appropriate). Although we have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties. However, as of September 30, 2014 and December 31, 2013, we have assessed the significance of the impact of the credit valuation adjustments on the overall valuation and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, we have determined that our derivative valuations in their entirety are classified in Level 2 of the fair value hierarchy. We have consistently applied these valuation techniques in all periods presented and believe we have obtained the most accurate information available for the types of derivative contracts we hold.
	Our investment in CBRE Strategic Partners Asia is based on the Level 3 valuation inputs applied by the Investment Manager of this investment company utilizing a mix of different approaches for valuing the underlying real estate related investments within the investment company. The approaches include the income approach, direct market comparison approach and the replacement cost approach for newer properties. For investments owned more than one year, except for investments under construction or incurring significant renovation, it is CBRE Strategic Partners Asia’s policy to obtain a third-party appraisal. For investments in real estate under construction or incurring significant renovation, the valuation analysis is prepared by the Investment Manager. On a quarterly basis, the Company obtains the financial results of CBRE Strategic Partners Asia and on an annual basis the Company receives audited financial statements.
	The following items are measured at fair value on a recurring basis at September 30, 2014 and December 31, 2013 (in thousands):

	Segment Disclosure
	As a result of the reassessment of our reportable segments during the period ended March 31, 2014, we view our consolidated property operations as two reportable segments: Industrial Properties and Office Properties. In addition, we had one non-reportable segment, which was Retail Properties. However, during the third quarter ended September 30, 2014 we sold our last remaining retail property, therefore, eliminating the non-reportable segment from future reportable presentations. We reclassified the prior period segment financial results to conform to the current year presentation. Management internally evaluates the operating performance and financial results of our segments based on net operating income. We also have certain general and administrative level activities including legal, accounting, tax preparation and shareholder servicing costs that are not considered separate operating segments.
	We evaluate the performance of our segments based on net operating income, defined as: rental income, tenant reimbursements and other property income less property and related expenses (operating and maintenance and real estate taxes) and excludes other non-property income and expenses, interest expense, depreciation and amortization, and corporate general and administrative expenses.

The Amended Indemnification Agreements generally contain the same terms and conditions as the original indemnification agreements entered into by and between us and each trustee and executive officer, except for the following changes: (i) requiring a final adjudication, not subject to appeal, of exceptions to indemnification coverage; (ii) providing enhanced protection for attorney-client privilege and prohibiting our ability to raise arguments regarding validity of the indemnification agreement; (iii) eliminating our option to assume the defense of an indemnitee; (iv) enhancing an indemnitee's ability to obtain reimbursement of defense costs; (v) prohibiting the cancellation of trustee and officer insurance coverage without notice to an indemnitee; (vi) creating primacy in our obligations to indemnify the indemnitee; and (vii) requiring us to provide information to an indemnitee to assist in such indemnitee's defense.
	The above description of the Amended Indemnification Agreements does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the form of amended and restated indemnification agreement, which is filed as Exhibit 10.1 to this Quarterly Report on Form 10-Q and is incorporated by reference into this Item 5 "Other Information."

Basis of Presentation and Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2014
Accounting Policies [Abstract]	'
Basis of Presentation and Principles of Consolidation	'
	Basis of Presentation and Principles of Consolidation
	The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP") and reflect the accounts of the Company, CSP OP and its consolidated subsidiaries. The Company consolidates its wholly-owned properties and joint ventures it controls through either 1) voting rights or similar rights or 2) by means other than voting rights if the Company is deemed to be the primary beneficiary of a variable interest entity. All intercompany accounts and transactions are eliminated in consolidation.
	Certain information and footnotes required for annual financial statement presentation have been condensed or excluded pursuant to Securities and Exchange Commission (the "SEC") rules and regulations. Accordingly, our interim financial statements do not include all of the information and disclosures required under GAAP for complete financial statements. In the opinion of management, all adjustments of a normal recurring nature considered necessary in all material respects to present fairly our financial position, results of our operations and cash flows as of and for the three and nine months ended September 30, 2014 have been made. The results of operations for the three and nine months ended September 30, 2014 are not necessarily indicative of the results of operations to be expected for the entire year. The condensed consolidated financial statements and notes thereto should be read in conjunction with our current Annual Report on Form 10-K, which contains the latest available audited consolidated financial statements and notes thereto, which are as of and for the year ended December 31, 2013.
Use of Estimates	'
	Use of Estimates
	The preparation of financial statements, in conformity with GAAP, requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Segment Information	'
	Segment Information
	Our chief operating decision-makers internally evaluate the operating performance and financial results of our portfolio based on Net Operating Income. We define "Net Operating Income" as: rental income, tenant reimbursements, and other property income less property and related expenses (operating and maintenance and real estate taxes) and excludes other non-property income and expenses, interest expense, depreciation and amortization, and corporate general and administrative expenses. During the first quarter of 2014, we reassessed our segment reporting and determined that the proper aggregation of our properties was by property type, Industrial Properties and Office Properties. Both of these operating segments meet the 10% quantitative reporting thresholds to be considered a reportable segment under GAAP and reflect the core operations of our business. Beginning with the reporting period ended March 31, 2014, we view our consolidated property operations as two reportable segments: Industrial Properties and Office Properties. In addition, we had one non-reportable segment, which was Retail Properties. However, during the third quarter ended September 30, 2014 we sold our last remaining retail property, therefore, eliminating the non-reportable segment from future reportable presentations. We have reclassified the prior period segment financial results to conform to the current year presentation.
Revenue Recognition and Valuation of Receivables	'
	Revenue Recognition and Valuation of Receivables
	All leases are classified as operating leases and minimum rents are recognized on a straight-line basis over the terms of the leases. The excess of rents recognized over amounts contractually due pursuant to the underlying leases is recorded as deferred rent. In connection with various leases, we have received irrevocable stand-by letters of credit totaling $14.8 million and $14.5 million as security for such leases at September 30, 2014 and December 31, 2013.
	Reimbursements from tenants, consisting of amounts due from tenants for common area maintenance, real estate taxes, insurance and other recoverable costs, are recognized as revenue in the period the expenses are incurred. Tenant reimbursements are recognized and presented on a gross basis, when we are the primary obligor with respect to incurring expenses and with respect to having the credit risk.
	Tenant receivables and deferred rent receivables are carried net of the allowances for uncollectible current tenant receivables and deferred rent. Management's determination of the adequacy of these allowances is based primarily upon evaluations of historical loss experience, individual receivables, current economic conditions, and other relevant factors. The allowances are increased or decreased through the provision for bad debts.
Translation of Non-U.S. Currency Amounts	'
	Translation of Non-U.S. Currency Amounts
	The financial statements and transactions of our United Kingdom real estate operation are recorded in their functional currency, namely the Great Britain Pound ("GBP") and are then translated into U.S. dollars ("USD").
	Assets and liabilities of this operation are denominated in the functional currency and are then translated at exchange rates in effect at the balance sheet date. Revenues and expenses are translated at the average exchange rate for the reporting period. Translation adjustments are reported in "Accumulated Other Comprehensive Income (Loss)," a component of Shareholders' Equity.
Transition and Listing Expenses	'
	Transition and Listing Expenses
	We incurred certain costs in connection with our transition from being an externally managed company to a self-managed company ("Transition Costs"). These Transition Costs consist of legal, consulting and other third-party service provider costs incurred by us in order to execute on our Board of Trustees' decision to become a self-managed company.
Listing	'
Listing	We incurred certain costs in connection with our Listing and our Tender Offer in 2013. These listing expenses consisted of legal, investment banking, share-based compensation, consulting and other third-party service provider costs incurred by us in order to complete our Listing and Tender Offer.
Income Taxes	'
	Income Taxes
	We elected to be taxed as a REIT under the Internal Revenue Code commencing with our taxable year ended December 31, 2004. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement that we generally distribute at least 90% of our REIT taxable income (determined without regard to the dividends paid deduction and excluding net capital gain). It is our current intention to adhere to these requirements and maintain our REIT qualification. As a REIT, we generally will not be subject to corporate level U.S. federal income tax on net income we distribute currently to our shareholders. If we fail to qualify as a REIT in any taxable year, then we will be subject to U.S. federal income taxes at regular corporate rates (including any applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if we qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income and property and to U.S. federal income and excise taxes on our undistributed taxable income, if any.
	ASC 740-10 Income Taxes requires recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements or tax returns. Under this method, deferred tax assets and liabilities are determined based on the differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. We did not have a liability for any unrecognized benefits as of September 30, 2014. The tax years from 2010 through 2013 remain open to examination by the taxing jurisdictions to which the Company is subject.
New Accounting Standards	'
	New Accounting Standards
	In April 2014, the FASB issued ASU No. 2014-08, Presentation of Financial Statements (Topic 205) and Property, Plant and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity, which requires only disposals representing a strategic shift in operations (i.e., a disposal of a major geographic area, a major line of business, or a major equity method investment) to be presented as discontinued operations. The standard also requires expanded disclosures about discontinued operations and is intended to provide financial statement users with information about the ongoing trends in a company's results from continuing operations. ASU No. 2014-08 is effective in the first quarter of 2015 for public entities with calendar year ends. However, companies are permitted to early adopt the standard, beginning in the first quarter of 2014, but only for disposals or classifications as held for sale that have not been reported in financial statements previously issued or available for issuance. We early adopted this standard in the first quarter of 2014 and the adoption did not have a material effect on our financial condition, results of operations, or disclosures.
	In May 2014, the FASB and IASB issued their final standard on revenue from contracts with customers. The standard, issued by the FASB as ASU 2014-09, outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including the guidance on real estate derecognition for most transactions. Entities have the option of using either a full retrospective or a modified approach to adopt the guidance in ASU 2014-09. For public entities, the ASU is effective for annual reporting periods (including interim reporting periods within those periods) beginning after December 15, 2016. Early application is not permitted. We are assessing the impact of this guidance on our consolidated financial statements and notes to our consolidated financial statements.
	In June 2014, the FASB issued ASU No. 2014-12, Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period. The ASU clarifies that entities should treat performance targets that can be met after the requisite service period of a share-based payment award as performance conditions that affect vesting. Therefore, an entity would not record compensation expense (measured as of the grant date without taking into account the effect of the performance target) related to an award for which transfer to the employee is contingent on the entity’s satisfaction of a performance target until it becomes probable that the performance target will be met. ASU No. 2014-12 will be effective for all entities for reporting periods (including interim periods) beginning after December 15, 2015, and early adoption is permitted. ASU 2014-12 may be adopted either prospectively for share-based payment awards granted or modified on or after the effective date, or retrospectively, using a modified retrospective approach. The modified retrospective approach would apply to share-based payment awards outstanding as of the beginning of the earliest annual period presented in the financial statements on adoption, and to all new or modified awards thereafter. The adoption of this guidance is not anticipated to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.
	In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements—Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern. The ASU provides guidance on determining when and how to disclose going-concern uncertainties in the financial statements. The new standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued. An entity must provide certain disclosures if conditions or events raise substantial doubt about the entity’s ability to continue as a going concern. The ASU applies to all entities and is effective for annual periods ending after December 15, 2016, and interim periods thereafter, with early adoption permitted. The adoption of this guidance is not anticipated to have a material impact on our consolidated financial statements or notes to our consolidated financial statements.
