CGG announced today the impact of the amendment of IAS 38 on CGG's multi-client library amortization pattern

Paris, France – March 03, 2016

The amendment of IAS 38 Intangible assets leads CGG to adapt its multi-client library amortization pattern as follows:

Each survey will be fully amortized over a 5 years period based on the following principles:

• o Based on the sales pattern, each survey will be amortized in a manner that reflects the pattern of consumption of its economic benefits during both prefunding and after sales periods.
• o Thereby, an amortization rate corresponding to the ratio of capitalized costs to total expected sales over the accounting life of the survey will be applied to each sales recognized. For 2016, and as applied conservatively by CGG since January 1st, 2014, such amortization rate will be 80%.
• o For certain large sales, as the case maybe, the amortization rate will be adjusted to reflect the commercial effects of price elements: would a special rebate be granted to a customer buying a large volume of data, it could then trigger a higher amortization rate.
• o In parallel with the primary amortization pattern here-above described, a secondary amortization pattern consisting in a straight-line amortization of the Gross Book Value of the survey over a 5 year period starting at the delivery date of the survey will supersede and prevail would its application lead to a higher accumulated amortization than for the primary amortization pattern.

In addition, an impairment assessment will continue to be performed on an annual basis (or more frequently, whenever there is an indication that a survey may be impaired).

According to CGG, these principles are fairly consistent with its multi-client business model characteristics. They have been reviewed by CGG's external auditors and comply with the amendment of IAS 38 as they reflect the expected pattern of consumption of the economic benefits of the multi-clients library.

These principles for the multi-clients library amortization will be applied prospectively with effect from January 1st, 2016.
