Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Litigation The Company is involved in litigation on a number of matters and is subject to certain claims, which arise in the normal course of business, none of which, in the opinion of management, is expected to have a material adverse effect on the Company's consolidated financial position, results of operations, or liquidity. Legal fees are expensed as incurred. After the announcement of the merger agreement with Equity One on November 14, 2016, a putative class action was filed on behalf of a purported stockholder in the Circuit Court for Duval County, Florida, under the following caption: Robert Garfield on Behalf of Himself and All Others Similarly Situated vs. Regency Centers Corporation, Martin E. Stein, Jr., John C. Schweitzer, Raymond L. Bank, Bryce Blair, C. Ronald Blankenship, J. Dix Druce, Jr., Mary Lou Fiala, David P. O'Connor, and Thomas G. Wattles, No. 16-2017-CA-000688-XXXX-MA, filed February 3, 2017. The class action alleged, among other matters, that the definitive joint proxy statement/prospectus filed by Regency and Equity One with the Securities and Exchange Commission (the “SEC”) on January 24, 2017 (the “Joint Proxy Statement/Prospectus”) omitted certain material information in connection with the merger. The complainant sought various remedies, including injunctive relief to prevent the consummation of the merger unless certain allegedly material information was disclosed and sought compensatory and rescissory damages in the event the merger was consummated without such disclosures. On February 17, 2017, the defendants entered into a stipulation of settlement with respect to the class action, pursuant to which the parties agreed, among other things, that Regency would make certain supplemental disclosures. The supplemental disclosures were made by Regency in the Current Report on Form 8-K filed by Regency with the SEC on February 17, 2017. The stipulation of settlement remains subject to court approval. Environmental The Company is also subject to numerous environmental laws and regulations as they apply to real estate pertaining to chemicals used by the dry cleaning industry, the existence of asbestos in older shopping centers, and underground petroleum storage tanks. The Company believes that the ultimate disposition of currently known environmental matters will not have a material effect on its financial position, liquidity, or operations. The Company can give no assurance that existing environmental studies with respect to the shopping centers have revealed all potential environmental contaminants or liabilities, that any previous owner, occupant or tenant did not create any material environmental condition not known to it, that the current environmental condition of the shopping centers will not be affected by tenants and occupants, by the condition of nearby properties, or by unrelated third parties, or that changes in applicable environmental laws and regulations or their interpretation will not result in additional environmental liability to the Company. Letters of Credit The Company has the right to issue letters of credit under the Line up to an amount not to exceed $50.0 million, which reduces the credit availability under the Line. These letters of credit are primarily issued as collateral on behalf of its captive insurance program and to facilitate the construction of development projects. As of September 30, 2017 and December 31, 2016, the Company had $5.9 million and $5.8 million, respectively, in letters of credit outstanding.
