The Company will evaluate the range of reasonably estimated losses and record an accrued liability based on the minimum amount in the range, unless an amount within the range is a better estimate than any other amount. In such cases, there may be an exposure to loss in excess of the amounts accrued. The Company evaluates quarterly whether further developments could affect the amount of the accrued liability previously established or would make a loss contingency both probable and reasonably estimable.The Company also provides disclosure when it is reasonably possible that a loss will be incurred or when it is reasonably possible that the amount of a loss will exceed the recorded liability. The Company reviews loss contingencies at least quarterly to determine whether the likelihood of loss has changed and to assess whether a reasonable estimate of the loss or range of loss can be made. This estimated range of possible loss is based upon currently available information and is subject to significant judgment and a variety of assumptions, and known and unknown uncertainties. The matters underlying the estimated range will change from time to time, and actual results may vary significantly from the current estimate.The Company is subject to a variety of litigation, claims, other disputes and governmental proceedings that arise from time to time in the ordinary course of its business. The Company cannot assure you that it will be successful in defending these matters. Based on current knowledge, the Company does not believe that loss contingencies arising from pending litigation, claims other disputes and governmental proceedings, including those described herein, will have a material adverse effect on the consolidated financial position or liquidity of the Company. However, in light of the inherent uncertainties involved in these matters, an adverse outcome in one or more of these matters could be material to the Company’s results of operations or cash flows for any particular reporting period.On January 4, 2011 the Company received notice from the Staff (the “Staff”) of the Securities and Exchange Commission (the “SEC”) of the initiation of an inquiry into the Company’s policies and practices concerning impairment of investment in real estate assets. On June 24, 2011, the Company received notice from the SEC that it has issued a related order of private investigation. The order designates officers of the SEC to take the testimony of the Company and third parties with respect to any or all of these matters. On January 20, 2015, the Company received a written “Wells Notice” from the Staff indicating the Staff’s preliminary determination to recommend that the SEC file an action against the Company for violations of certain federal securities laws. The Staff has informed the Company that the Wells Notice relates to historical accounting and disclosure practices and real estate asset valuations principally as reflected in the Company’s financial results for 2010, 2009 and prior periods. A Wells Notice is neither a formal allegation of wrongdoing nor a finding that any violations of law have occurred. Rather, it provides the Company with an opportunity to respond to issues raised by the Staff and offer its perspective prior to any SEC decision to institute proceedings. If the Staff makes a recommendation to the SEC, the recommendations may involve a civil injunctive action, public administrative proceeding, and/or cease-and-desist proceeding, and may seek remedies that include an injunction and/or cease and desist order, disgorgement, pre-judgment interest, and civil money penalties. The Company is fully cooperating with the investigation. However, it is unable to predict the outcome of the investigation, any potential enforcement actions or any other impact on the Company that may arise as a result of such investigation. The Company has not established a liability for this matter, because it believes that the probability of loss related to this matter and an estimate of the amount of loss, if any, are not determinable at this time.The Company is subject to costs arising out of environmental laws and regulations, which include obligations to remove or limit the effects on the environment of the disposal or release of certain wastes or substances at various sites, including sites which have been previously sold. It is the Company’s policy to accrue and charge against earnings environmental cleanup costs when it is probable that a liability has been incurred or range of loss can be reasonably estimated. As assessments and cleanups proceed, these accruals are reviewed and adjusted, if necessary, as additional information becomes available.The Company’s former paper mill site in Gulf County and certain adjacent properties are subject to various Consent Agreements and Brownfield Site Rehabilitation Agreements with the Florida Department of Environmental Protection. The paper mill site has been rehabilitated by Smurfit-Stone Container Corporation in accordance with these agreements. The Company is in the process of assessing certain adjacent properties. Management is unable to quantify future rehabilitation costs above present accruals at this time or provide a reasonably estimated range of loss.Other litigation, claims, other disputes and governmental proceedings, including environmental matters, are pending against the Company. Aggregate environmental-related accruals were $0.5 million and $1.1 million at December 31, 2014 and 2013, respectively. Although the final resolution of the environmental litigation matters or governmental proceedings is not expected to have a material effect on the Company’s consolidated financial condition, it is possible that any final outcome could have a material impact on the results of operations or cash flows of the Company.The Company has retained certain self-insurance risks with respect to losses for third party liability and property damage, including our timber assets.At December 31, 2014 and 2013, the Company was required to provide surety bonds that guarantee completion of certain infrastructure in certain development projects and mitigation banks of $8.3 million and $14.1 million, respectively. At December 31, 2014, the Company has a total of $5.0 million in purchase obligations, which $4.3 million are for 2015, $0.3 million are for 2016 and $0.4 million are for 2017.The construction loan entered into by the Pier Park North joint venture requires the Company to provide certain guarantees and covenants as described in Note 9,Real Estate Joint Ventures. As part of the AgReserves Sale and certain sales of timberlands in 2007 and 2008, the Company generated significant tax gains. The installment notes structure allowed the Company to defer the resulting tax liability of $61.8 million until 2022 - 2024 and $69.3 million until 2029, respectively, the maturity dates for the Installment Notes. The Company has a deferred tax liability related to the gains in connection with these sales. |
