We implement our business strategies with our primary goal in mind: to provide our shareholders with a secure, growing dividend and long-term appreciation from our real estate portfolio. Lexington generates rental revenue and cash available for distribution by acquiring, owning, investing in, and managing properties in which a corporate tenant has made a long-term commitment through a net lease.
We grow our portfolio primarily by executing two basic strategies: buying properties and leasing them back to the sellers under net leases, or by acquiring properties already subject to net leases. We also make mortgage and mezzanine loans secured by single tenant buildings. Through its investments, Lexington provides funds to corporations seeking to raise capital through the sale of their real estate holdings, and to developers who are engaged in "build-to-suit" projects for corporate users.
Portfolio diversification is central to our investment strategy as we seek to create and maintain an asset base that provides steady growth while being insulated against rising property operating expenses, regional recessions, industry specific downturns and fluctuations in property values and market rent levels. Regardless of capital market and economic conditions, we stay focused on enhancing operating results, improving portfolio quality, mitigating risks relating to interest rates and the real estate cycle, and implementing strategies where our management skills and real estate expertise can add value. Our goal is to provide shareholders with consistent growth and returns throughout any business cycle.
