These forward - looking statements, which are based on current expectations, estimates and projections about the industry and markets in which MAA operates and beliefs of and assumptions made by MAA management, involve uncertainties that could significantly affect the financial results of MAA . Words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “seeks,” “estimates,” and variations of such words and similar expressions are intended to identify such forward - looking statements, which are not historical in nature . In this presentation, forward - looking statements include, but are not limited to, statements about forecasted 2018 operating results, expected benefits and synergies from the merger with Post Properties, Inc . and the timing of those benefits and synergies, the anticipated value of current development projects and lease - up communities, estimated costs of property development, the anticipated timing of completion of current development projects and the stabilization of such projects, MAA’s future development projects, the anticipated stabilization of communities in lease - up, the anticipated scope of MAA’s future redevelopment activities and projected redevelopment costs and incremental rent growth, and other information that is not historical .

These statements are not guarantees of future performance and involve certain risks, uncertainties and assumptions that are difficult to predict . Although MAA believes the expectations reflected in any forward - looking statements are based on reasonable assumptions, MAA can give no assurance that its expectations will be achieved, and therefore actual outcomes and results may differ materially from what is expressed or forecasted in such forward - looking statements . Some of the factors that may affect outcomes and results include, but are not limited to : inability to generate sufficient cash flows due to market conditions, changes in supply and/or demand, competition, uninsured losses, changes in tax and housing laws, or other factors ; exposure as a multifamily - focused REIT to risks inherent in investments in a single industry and sector ; adverse changes in real estate markets ; failure of new acquisitions to achieve anticipated results or be efficiently integrated ; failure of development communities to be completed, if at all, within budget and on a timely basis or to lease - up as anticipated ; unexpected capital needs ; changes in operating costs, including real estate taxes, utilities and insurance costs ; losses from catastrophes in excess of our insurance coverage ; level and volatility of interest or capitalization rates or capital market conditions ; the effect of any rating agency actions ; inability to attract and retain qualified personnel ; cyberliability or potential liability for breaches of our privacy or information security systems ; adverse legislative or regulatory tax changes ; litigation and compliance costs associated with laws requiring access for disabled persons ; difficulty in integrating MAA’s and Post Properties’ merger ; and those additional risks and factors discussed in reports filed with the Securities and Exchange Commission by MAA from time to time, including those discussed under the heading “Risk Factors” in MAA’s most recently filed Annual Report on Form 10 - K and Quarterly Reports on Form 10 - Q .
