Joint Stock Company "Sevmorgeo" Outstanding Trade Receivable Update

The Company's subsidiary, WGP Energy Services Ltd ("WGP"), has received a written notification from the new General Director of its client, Joint Stock Company "Sevmorgeo" ("SMG"), that SMG now claims it has not received any documentation confirming that WGP fulfilled its obligations and therefore no longer recognises the compensation due to WGP of $3.3m, excluding accrued interest, for services provided in Ecuador during 2013. This is despite SMG's previous acceptance of all invoices issued by WGP and numerous correspondences from the former General Director of SMG confirming the unpaid compensation, including a legal confirmation executed by the parties in January 2014.

The Company reported in the Interim Report for the six months to 30 June 2014 (available at http://thalassaholdingsltd.com/documents/NP0914-1583_P08FINAL.pdf) that: "in a worst case scenario we may not recover the outstanding trade receivable or the repatriation costs which, in the aggregate, amount to approximately US$4.1m (a non-cash item of US$3.3m being the outstanding trade receivable, and a cash item of US$0.8m relating to repatriation costs)".

As part of the review of the Company's balance sheet for the year to 31 December 2014, the Board had already intended to make a provision against this outstanding receivable of US$3.3m, excluding accrued interest. Whilst the contract with SMG clearly states that demobilisation and repatriation costs are to SMG's account, the Company will also recognise a charge in the 2014 accounts for repatriation and remediation of its equipment to Europe as indicated above.

Thalassa's Chairman, Duncan Soukup commented:

"Notwithstanding the position adopted by SMG's new General Director, we are hopeful that this matter can be resolved amicably. WGP has successfully operated for its Russian clients, including SMG, for over 19 years and will continue to pursue further opportunities with Russian clients as soon as the geopolitical situation allows.

The Board remains positive for the outlook in 2015 and the Company is experiencing an encouraging increase in order enquiry. The Company's cash position remains strong at US$15.7m, including US$2.2m of which is restricted."
