Following the acquisition of (i) the Methane Rita Andrea and the Methane Jane Elizabeth and (ii) the Methane Alison Victoria, the Methane Shirley Elisabeth and the Methane Heather Sally, the Partnership, through its subsidiaries (i) GAS-sixteen Ltd. and GAS-seventeen Ltd. and (ii) GAS-nineteen Ltd., GAS-twenty Ltd. and GAS-twenty one Ltd., respectively, is counter guarantor for the acquisition from BG Group plc of 83.33% of depot spares with an aggregate value of $6,000, of which $660 have been purchased and paid as of June 30, 2018 by GasLog. These spares are expected to be acquired before the end of the initial term of the charter party agreements.

Additionally, in September 2017, GasLog LNG Services entered into maintenance agreements with Wartsila Greece S.A. in respect of two of the Partnership's LNG carriers. The agreements ensure dynamic maintenance planning, technical support, security of spare parts supply, specialist technical personnel and performance monitoring.

Various claims, suits and complaints, including those involving government regulations, arise in the ordinary course of the shipping business. In addition, losses may arise from disputes with charterers, environmental claims, agents and insurers and from claims with suppliers relating to the operations of the Partnership's vessels. Currently, management is not aware of any such claims or contingent liabilities requiring disclosure in the consolidated financial statements.
