4. SUPPLEMENTAL CONSOLIDATED FINANCIAL STATEMENT INFORMATION

Except for the items mentioned below, no other balance sheet opening balances were materially impacted at January 1, 2017 for the adoption of Topic 606.

Deferred Costs (in thousands)

The opening balance of deferred cost was $2,991 and $3,668 at January 1, 2018 and 2017, respectively. The Company’s prepaid expenses and other current assets at June 30, 2018 and 2017 included deferred costs incurred to fulfill contracts with customers of $7,367 and $1,952, respectively.

Deferred costs at June 30, 2018 compared to January 1, 2018 increased primarily as a result of more projects with higher deferred fulfillment costs impacted by reimbursable third party charges relating to helicopter, permitting, surveying, drilling and line clearing. Deferred cost balance decreased when comparing June 30, 2017 to January 1, 2017 primarily due to the completion of several projects during that six month period that had significant deferred fulfillment costs at January 1, 2017.

The amount of total deferred costs amortized for the second quarter and first six months of 2018 was $7,248 and $14,247, respectively. The amount of total deferred cost amortized for the second quarter and first six months of 2017 was $10,273 and $23,288, respectively. There were no material impairment losses incurred during these periods.

Deferred Revenue (in thousands)

The opening balance of deferred revenue was $6,314 and $5,385 at January 1, 2018 and 2017, respectively. The Company’s deferred revenue at June 30, 2018 and 2017 was $7,103 and $8,995, respectively.

Deferred revenue did not change significantly from January 1, 2018 to June 30, 2018 primarily as a result of increases in deferred revenue for unfinished projects mostly offset by the completion of several projects with prepayments from clients. Deferred revenue at June 30, 2017 compared to January 1, 2017 increased primarily as a result of large prepayments from clients with an anticipated large amount of third party reimbursables partially offset by completed projects that had deferred revenue at January 1, 2017.

Revenue recognized for the second quarter and first six months of 2018 that was included in the contract liability balance at the beginning of 2018 was $1,628 and $5,311, respectively. Revenue recognized for the second quarter and first six months of 2017 that was included in the contract liability balance at the beginning of 2017 was $55 and $4,710, respectively.
