Fiduciary/Claymore MLP Opportunity Fund Provides Update Regarding Deferred Tax Liabilities and Increase to Net Asset Value

LISLE, Ill., Nov. 15, 2013 (GLOBE NEWSWIRE) -- FMO Fiduciary/Claymore MLP Opportunity Fund (the "Fund") announced today that as a result of changes in the Fund's assumptions regarding state tax rates to which the Fund will be subject, the Fund has adjusted its accrued deferred income tax liability. Based upon current tax rates, these changes will have a positive impact on the Fund's net asset value.

Because of the Fund's concentration in master limited partnership ("MLP") investments, the Fund is not eligible to be treated as a "regulated investment company" under the Internal Revenue Code of 1986, as amended (the "Code"). Instead, the Fund is treated as a regular corporation for U.S. federal income tax purposes and, as a result, unlike most investment companies, is subject to corporate income tax to the extent the Fund recognizes taxable income.

The Fund accrues a deferred income tax liability, at an assumed federal, state and local income tax rate, for its future tax liability associated with the capital appreciation of its investments and the distributions received by the Fund on equity securities of MLPs considered to be return of capital. The Fund's deferred tax liability is estimated using estimates of effective tax rates expected to apply to taxable income in the years such taxes are realized. As a result of changes in the Fund's assumptions regarding applicable state tax rates, the Fund has reduced its deferred tax liability by approximately $13 million, resulting in an increase in net asset value per common share of $0.40.

Upon the sale of an equity security in an MLP, the Fund generally will be liable for any previously deferred taxes. No assurance can be given that such taxes will not exceed the Fund's deferred tax assumptions for purposes of computing the Fund's net asset value per share, which would result in an immediate reduction of the Fund's net asset value per share. For purposes of estimating the Fund's deferred tax liability for financial statement reporting and determining its net asset value, the Fund will be required to rely, to some extent, on information provided by the MLPs in which it invests. Such information may not be received in a timely manner, with the result that the Fund's estimates regarding its deferred tax liability could vary dramatically from the Fund's actual tax liability and, as a result, the determination of the Fund's actual tax liability may have a material impact on the Fund's net asset value. From time to time, the Fund may modify its estimates or assumptions regarding its deferred tax liability as new information becomes available. Modifications of such estimates or assumptions or changes in applicable tax law could result in increases or decreases in the Fund's net asset value per share, which could be material.

The Fund is a non-diversified, closed-end management investment company. The Fund's investment objective is to provide a high level of after-tax total return with an emphasis on current distributions paid to shareholders. No assurance can be given that the Fund's investment objective will be achieved.

The Fund anticipates that a significant portion of the distributions received by the Fund from the MLPs in which it invests will consist of return of capital. If this expectation is not realized, the Fund will have a larger corporate income tax expense sooner than expected. Moreover, although MLP distributions that are treated as returns of capital are generally not taxable to the Fund to that extent, such returns of capital reduce the Fund's tax basis in its investments, resulting in potential increased gains (or decreased losses) upon dispositions of such investments. While the Fund will generally seek to maximize the portion of the Fund's distributions to common shareholders that will consist of return of capital, no assurance can be given in this regard.
