Income Taxes	6. INCOME TAXES Net cash paid for income taxes for the years ended December 31, 2015, 2014 and 2013 of $341,000, $316,000 and $173,000, respectively, includes amounts related to state and local income taxes for jurisdictions that do not follow the federal tax rules, which are provided for in property costs in our consolidated statements of operations. Earnings and profits (as defined in the Internal Revenue Code) are used to determine the tax attributes of dividends paid to stockholders and will differ from income reported for consolidated financial statements purposes due to the effect of items which are reported for income tax purposes in years different from that in which they are recorded for consolidated financial statements purposes. The federal tax attributes of the common dividends for the years ended December 31, 2015, 2014 and 2013 were: ordinary income of 83.8%, 43.9% and 94.4%, capital gain distributions of 16.2%, 56.1% and 5.6% and non-taxable distributions of 0.0%, 0.0% and 0.0%, respectively. To qualify for taxation as a REIT, we, among other requirements such as those related to the composition of our assets and gross income, must distribute annually to our stockholders at least 90% of our taxable income, including taxable income that is accrued by us without a corresponding receipt of cash. We cannot provide any assurance that our cash flows will permit us to continue paying cash dividends. Should the Internal Revenue Service (“IRS”) successfully assert that our earnings and profits were greater than the amount distributed, we may fail to qualify as a REIT; however, we may avoid losing our REIT status by paying a deficiency dividend to eliminate any remaining earnings and profits. We may have to borrow money or sell assets to pay such a deficiency dividend. Although tax returns for the years 2012, 2013 and 2014, and tax returns which will be filed for the year ended 2015, remain open to examination by federal and state tax jurisdictions under the respective statute of limitations, we have not currently identified any uncertain tax positions related to those years and, accordingly, have not accrued for uncertain tax positions as of December 31, 2015 or 2014. However, uncertain tax matters may have a significant impact on the results of operations for any single fiscal year or interim period. The IRS has allowed the use of a procedure, as a result of which we could satisfy the REIT income distribution requirement by making a distribution on our common stock comprised of (i) shares of our common stock having a value of up to 80% of the total distribution and (ii) cash in the remaining amount of the total distribution, in lieu of paying the distribution entirely in cash. In January 2015, we received a private letter ruling from the IRS that allows us to use such a procedure. On November 25, 2015, our Board of Directors declared a special dividend of $0.22 per share (the “Special Dividend”). The Special Dividend was payable in either common stock or cash. The aggregate amount of cash to be distributed by the Company was a minimum of 20% of the total distribution and a maximum of 40% of the total distribution, with the remainder to be paid in shares of common stock. As result, we issued 255,340 shares of common stock and made cash payments aggregating $2,941,000 to our shareholders. In the third quarter of 2013, we submitted to the IRS a request seeking a ruling that a portion of the payments we received from the Marketing Estate, including amounts related to the Litigation Funding Agreement (see Note 2 for additional information regarding the Lukoil Settlement and the Litigation Funding Agreement), be treated either as qualifying income or excluded from gross income for the purposes of the REIT qualification gross income tests either as a matter of law or pursuant to the discretionary authority granted by Congress to the IRS to determine whether certain types of income are an outgrowth of a REIT’s business of owning and operating real estate. In January 2014, we received a favorable ruling from the IRS indicating that a portion of the payments received from the Marketing Estate will be treated as qualifying income and the remainder will be excluded from gross income for the purposes of the REIT qualification gross income tests. Therefore, none of the cash flow received from the Marketing Estate, including amounts related to the Litigation Funding Agreement, will be treated as non-qualifying income for purposes of the REIT qualification gross income tests. During 2015, we received distributions from Marketing Estate in the amount of $18,177,000, which will be treated as non-qualifying income for REIT qualification gross income tests.
