to qualify as a reit , we must meet a number of organizational and operational requirements , including a requirement to distribute at least 90% ( 90 % ) of our adjusted taxable income to our stockholders .
management intends to continue to adhere to these requirements and to maintain our reit status .
as a reit , we are entitled to a tax deduction for some or all of the dividends we pay to shareholders .
accordingly , we generally will not be subject to federal income taxes as long as we distribute an amount equal to or in excess of our taxable income currently to shareholders .
we are also generally subject to federal income taxes on any taxable income that is not currently distributed to its shareholders .
if we fail to qualify as a reit in any taxable year , we will be subject to federal income taxes and may not be able to qualify as a reit for four subsequent taxable years. .
