We and our labor contractors are subject to government mandated wage and benefit laws and regulations. In addition, current or future federal or state healthcare legislation and regulation, including the Affordable Care Act, may increase our medical costs or the medical costs of our labor contractors that could be passed on to us. Many factors may affect the cost and supply of citrus, including external conditions, commodity market fluctuations, changes in governmental laws and regulations, tariffs, agricultural programs, severe and prolonged weather conditions and natural disasters. Increased costs for products can negatively impact our operating results and there can be no assurance that they will not adversely affect our operating results in the future. We depend on third party providers of transportation and have no control over such third parties. An extended interruption in our ability to harvest and haul our products could have a material adverse effect on our business, financial condition and results of operations. Similarly, any extended disruption in the distribution of our products could have a material adverse effect on our business, financial condition and results of operations. While we believe we are adequately insured and would attempt to transport our products by alternative means if we were to experience an interruption due to strike, natural disasters or otherwise, we cannot be sure that we would be able to do so or be successful in doing so in a timely and cost-effective manner. In the fiscal years ended September 30, 2019, 2018 and 2017 we paid approximately $2,755,000, $3,089,000 and $3,106,000 in real estate taxes, respectively. These taxes were based upon the agricultural use (“Green Belt”) values determined by the county property appraisers in which counties we own land, of approximately $91,312,000, $104,017,000 and $105,496,000 for each of the fiscal years ended September 30, 2019, 2018 and 2017 respectively, which differs significantly from the fair values determined by the county property appraisers of approximately $514,330,000, $537,183,000 and $539,790,000, respectively. Changes in state law or county policy regarding the granting of agricultural classification or calculation of "Green Belt" values or average millage rates could significantly impact our results of operations, cash flows and/or financial position. Our agricultural business involves the use of herbicides, fertilizers and pesticides, some of which may be considered hazardous or toxic substances. We may be deemed liable and have to pay for the costs or damages associated with the improper application, accidental release or the use or misuse of such substances. Our insurance may not be adequate to cover such costs or damages, or may not continue to be available at a price or under terms that are satisfactory to us. In such cases, if we are required to pay significant costs or damages, it could materially adversely affect our business, results of operations, financial condition and cash flows. We are subject to various laws and regulations relating to the operation of our properties, which are administered by numerous federal, state and local governmental agencies. We face a potential for environmental liability by virtue of our ownership of real estate property. If hazardous substances (including herbicides and pesticides used by us or by any persons leasing our lands) are discovered emanating from any of our lands and the release of such substances presents a threat of harm to the public health or the environment, we may be held strictly liable for the cost of remediation of these hazardous substances. In addition, environmental laws that apply to a given site can vary greatly according to the site’s location, its present and former uses, and other factors such as the presence of wetlands or endangered species on the site. Management monitors environmental legislation and requirements and makes every effort to remain in compliance with such regulations. Furthermore, we require lessees of our properties to comply with environmental regulations as a condition of leasing. We also purchase insurance for environmental liability when it is available; however, these insurance contracts may not be adequate to cover such costs or damages or may not continue to be available at prices and terms that would be satisfactory. It is possible that in some cases the cost of compliance with these environmental laws could exceed the value of a particular tract of land, make it unsuitable for use in what would otherwise be its highest and best use, and/or be significant enough that it would materially adversely affect us. 12 Increases in commodity or raw product costs, such as fuel and chemical costs, could adversely affect our operating results. We are subject to transportation risks. We benefit from reduced real estate taxes due to the agricultural classification of a majority of our land. Changes in the classification or valuation methods employed by county property appraisers could cause significant changes in our real estate property tax liabilities. Liability for the use of fertilizers, pesticides, herbicides and other potentially hazardous substances could increase our costs. Compliance with applicable environmental laws may substantially increase our costs of doing business which could reduce our profits.
