Environmental Remediation Obligations [Abstract]
ENVIRONMENTAL OBLIGATIONS	5. ENVIRONMENTAL OBLIGATIONS We are subject to numerous existing federal, state and local laws and regulations, including matters relating to the protection of the environment such as the remediation of known contamination and the retirement and decommissioning or removal of long-lived assets including buildings containing hazardous materials, USTs and other equipment. Environmental costs are principally attributable to remediation costs which include installing, operating, maintaining and decommissioning remediation systems, monitoring contamination and governmental agency reporting incurred in connection with contaminated properties. We seek reimbursement from state UST remediation funds related to these environmental costs where available. In July 2012, we purchased for $3,062,000 a ten-year pollution legal liability insurance policy covering all of our properties for pre-existing unknown environmental liabilities and new environmental events. The policy has a $50,000,000 aggregate limit and is subject to various self-insured retentions and other conditions and limitations. Our intention in purchasing this policy is to obtain protection predominantly for significant events. No assurances can be given that we will obtain a net financial benefit from this investment. We enter into leases and various other agreements which allocate between the parties responsibility for known and unknown environmental liabilities at or relating to the subject premises. We are contingently liable for these environmental obligations in the event that the counterparty to the agreement does not satisfy them. For all of our triple-net leases, our tenants are directly responsible for remediation of environmental contamination that arises during the term of their tenancy, for compliance with various environmental laws and regulations as the operators of our properties, and for the retirement and decommissioning or removal of all or a negotiated percentage of USTs and other equipment. Under the terms of our leases covering properties previously leased to Marketing, we have agreed to remediate environmental contamination that exists at the premises at the commencement of the lease and is either known at the time the lease commences or is discovered by the tenant during the first ten years of the lease term, to within applicable regulatory standards (“Closure”), at which time our environmental liability under the lease for remediation of that contamination will be deemed satisfied. Under most of our other triple net leases, responsibility for remediation of all environmental contamination discovered during the term of the lease (including contamination that existed prior to commencement of the lease) is contractually allocated to our tenant. Under the Master Lease, Marketing was responsible to pay for the retirement and decommissioning or removal of USTs at the end of their useful life or earlier if circumstances warranted as well as remediation of environmental contamination Marketing caused and all unknown environmental liabilities discovered during the term of the Master Lease (collectively, the “Marketing Environmental Liabilities”). In the fourth quarter of 2011, we accrued for the Marketing Environmental Liabilities because we concluded that Marketing would not be able to perform them. A liability has not been accrued for environmental obligations that are the responsibility of any of our current tenants based on our tenant’s history of paying such obligations and/or our assessment of its financial ability and intent to pay such costs. However, there can be no assurance that our assessments are correct or that our tenants who have paid their obligations in the past will continue to do so. As part of the triple-net leases whose term commenced through September 30, 2013, we transferred title of the USTs to our tenants and the obligation to pay for the retirement and decommissioning or removal of USTs at the end of their useful life or earlier if circumstances warranted was fully or partially transferred to our new tenants. Accordingly, through September 30, 2013, we removed $12,136,000 of asset retirement obligations and $10,269,000 of net asset retirement costs related to USTs from our balance sheet. The cumulative net amount of $1,867,000 is recorded as deferred rental revenue and will be recognized on a straight-line basis as additional revenues from rental properties over the terms of the various leases. (See note 2 for additional information.) It is possible that our assumptions regarding the ultimate allocation method and share of responsibility that we used to allocate environmental liabilities may change, which may result in material adjustments to the amounts recorded for environmental litigation accruals and environmental remediation liabilities. We are required to accrue for environmental liabilities that we believe are allocable to others under various other agreements if we determine that it is probable that the counterparty will not meet its environmental obligations. The ultimate resolution of these matters could cause a material adverse effect on our business, financial condition, results of operations, liquidity, ability to pay dividends or stock price. The estimated future costs for known environmental remediation requirements are accrued when it is probable that a liability has been incurred and a reasonable estimate of fair value can be made. The accrued liability is the aggregate of the best estimate of the fair value of cost for each component of the liability net of estimated recoveries from state UST remediation funds considering estimated recovery rates developed from prior experience with the funds. Environmental exposures are difficult to assess and estimate for numerous reasons, including the extent of contamination, alternative treatment methods that may be applied, location of the property which subjects it to differing local laws and regulations and their interpretations, as well as the time it takes to remediate contamination. In developing our liability for estimated environmental remediation obligations on a property by property basis, we consider among other things, enacted laws and regulations, assessments of contamination and surrounding geology, quality of information available, currently available technologies for treatment, alternative methods of remediation and prior experience. Environmental accruals are based on estimates which are subject to significant change, and are adjusted as the remediation treatment progresses, as circumstances change and as environmental contingencies become more clearly defined and reasonably estimable. Environmental remediation obligations are initially measured at fair value based on their expected future net cash flows which have been adjusted for inflation and discounted to present value. As of September 30, 2013 and December 31, 2012, we had accrued $45,169,000 and $46,150,000, respectively, as our best estimate of the fair value of reasonably estimable environmental remediation obligations net of estimated recoveries and obligations to remove USTs. Environmental liabilities are accreted for the change in present value due to the passage of time and, accordingly, $2,119,000 and $2,250,000 of net accretion expense was recorded for the nine months ended September 30, 2013 and 2012, respectively, which is included in environmental expenses. In addition, during the nine months ended September 30, 2013 and 2012, we recorded credits to environmental expenses included in continuing operations and to earnings from operating activities in discontinued operations in our consolidated statements of operations aggregating $1,031,000 and $2,859,000, respectively, where decreases in estimated remediation costs exceeded the depreciated carrying value of previously capitalized asset retirement costs. Environmental expenses also include project management fees, legal fees and provisions for environmental litigation loss reserves. During the nine months ended September 30, 2013 and 2012, we increased the carrying value of certain of our properties by $8,657,000 and $4,420,000, respectively, due to increases in estimated remediation costs. The recognition, and subsequent changes in estimates, in environmental liabilities and the increase or decrease in carrying value of the properties are non-cash transactions which do not appear on the face of the consolidated statements of cash flows. Capitalized asset retirement costs are being depreciated over the estimated remaining life of the underground storage tank, a ten year period if the increase in carrying value related to environmental remediation obligations or such shorter period if circumstances warrant, such as the remaining lease term for properties we lease from others. Depreciation and amortization expense included in continuing operations and earnings from operating activities in discontinued operations in our consolidated statements of operations for the nine months ended September 30, 2013 and 2012 aggregated $1,648,000 and $4,492,000, respectively, for depreciation related to capitalized asset retirement costs. Capitalized asset retirement costs were $22,423,000 and $23,549,000 as of September 30, 2013 and December 31, 2012, respectively. We cannot predict what environmental legislation or regulations may be enacted in the future or how existing laws or regulations will be administered or interpreted with respect to products or activities to which they have not previously been applied. We cannot predict if state UST fund programs will be administered and funded in the future in a manner that is consistent with past practices and if future environmental spending will continue to be eligible for reimbursement at historical recovery rates under these programs. Compliance with more stringent laws or regulations, as well as more vigorous enforcement policies of the regulatory agencies or stricter interpretation of existing laws, which may develop in the future, could have an adverse effect on our financial position, or that of our tenants, and could require substantial additional expenditures for future remediation. In view of the uncertainties associated with environmental expenditure contingencies, we are unable to estimate ranges in excess of the amount accrued with any certainty; however, we believe it is possible that the fair value of future actual net expenditures could be substantially higher than amounts currently recorded by us. Adjustments to accrued liabilities for environmental remediation obligations will be reflected in our financial statements as they become probable and a reasonable estimate of fair value can be made. Future environmental expenses could cause a material adverse effect on our business, financial condition, results of operations, liquidity, ability to pay dividends or stock price.
