Magellan Petroleum Announces Receipt of Australian Tax Office Position Papers

HARTFORD, Conn., Sept. 5 /PRNewswire-FirstCall/ -- Magellan Petroleum Corporation (Nasdaq: MPET; ASX: MGN) ("Magellan") announced that its 100% owned subsidiary, Magellan Petroleum Australia Limited ("MPAL"), has received tax position papers from The Australian Tax Authority ("ATO").

As previously disclosed, the ATO has conducted an audit of the Australian income tax returns of MPAL and its wholly-owned subsidiaries for the years 1997- 2005. The audit focused on certain income tax deductions claimed by Paroo Petroleum Pty. Ltd. ("PPPL"), a wholly-owned finance subsidiary of MPAL, related to the write-off of outstanding loans made by PPPL to other entities within the MPAL group of companies. As a result of this audit, the ATO has issued "position papers" which set forth its opinions that these previous deductions should be disallowed, resulting in additional income taxes being payable by MPAL and its subsidiaries. In the position papers, the ATO sets out the legal basis for its conclusions. It is important to note that the position papers are not assessments of additional taxes.

In a comprehensive audit conducted by the ATO in the period 1992-94, the ATO concluded that PPPL was carrying on business as a money lender and accordingly, should, for taxation purposes, account for its interest income on an accruals basis rather than a cash basis. MPAL accepted this conclusion and from that point has been determining its annual Australian taxation liability on this basis (including claiming deductions for bad debts as a money lender).

Recently, the ATO appears to have taken a more aggressive approach with respect to its views regarding income tax deductions attributable to in-house finance companies. Since this change in approach, the ATO has commenced audits of a number of companies involving, among other issues, the appropriate treatment of bad debt deductions taken by in-house finance companies. Magellan understands that, at this time, while there have been negotiated settlements in relation to some of these audits, none of them has reached final resolution in court.

With issuance of the position papers, MPAL now has until October 12, 2007, subject to possible extension, to respond to the ATO's positions and to state its legal positions. MPAL has retained the services of experienced Australian tax counsel, and will also be represented by its Australian tax advisors, Ernst and Young.

MPAL intends to respond to the ATO position papers within the required time frame and refute the positions taken by the ATO. The ATO will consider MPAL's response and normally respond within a month. It could then agree with MPAL that no tax is due or issue formal assessments for some amount of taxes, interest and penalties. MPAL would then have an opportunity to formally object to any assessments and the ATO would determine its response to MPAL's objections, which it could accept or reject, in whole or in part. MPAL then would have an opportunity to appeal (against any assessment) to the Administrative Appeals Tribunal or to the Australian Courts. In the period when any such appeal is being determined, interest will continue to accrue on any outstanding amounts. However, MPAL may be able to limit the accrual of further interest by payment of an agreed sum to the ATO (which would be deposited into an escrow account) until the parties either reach a negotiated agreement or the income tax dispute is settled in the Australian Courts.

The ATO has indicated in the position papers that the increase in taxes arising from its proposed positions would be (Aus.) $13,392,460, plus possible interest and penalties, which could be substantial and exceed the amount of the increased taxes asserted by the ATO. If assessments of this amount are issued by the ATO, and upheld by the Australian courts, such assessments would have a material adverse impact on the Company's financial condition, results of operations and cash flows.
