STEINHAUSEN, Switzerland, July 30, 2018 (GLOBE NEWSWIRE) -- Transocean Ltd. (NYSE: RIG) today reported net loss attributable to controlling interest of $1.135 billion, $2.46 per diluted share, for the three months ended June 30, 2018.

Second quarter 2018 results included net unfavorable items of $1.117 billion, or $2.42 per diluted share, as follows:

$548 million, $1.18 per diluted share, loss on impairment of three floaters previously announced for retirement;
$463 million, $1.00 per diluted share, associated with a goodwill impairment charge;
$91 million, $0.20 per diluted share, in discrete tax expense;
$11 million, $0.03 per diluted share, in restructuring charges;
$3 million, $0.01 per diluted share, loss on impairment of the deepwater floater asset group; and
$1 million loss related to the early retirement of debt, offset by gain on disposal of assets.

After consideration of these net unfavorable items, second quarter 2018 adjusted net loss was $18 million, or $0.04 per diluted share.

Contract drilling revenues for the three months ended June 30, 2018, sequentially increased $126 million to $790 million. The increase was primarily due to a full quarter’s contribution from the four, CAT-D harsh environment semisubmersibles acquired from Songa in January 2018 and the newbuild ultra-deepwater drillship, Deepwater Poseidon, that commenced operations in February 2018. The second quarter was also favorably impacted by higher revenue efficiency and utilization on the company’s ultra-deepwater fleet.

Contract drilling revenues included customer early termination fees of $37 million on the Discoverer Clear Leader, a decrease of $1 million from the prior quarter. The second quarter also included a non-cash revenue reduction of $30 million from contract intangible amortization associated with the Songa acquisition.

Operating and maintenance expense was $431 million, compared with $424 million in the prior quarter. The second quarter included a full quarter’s activity from both the Songa rigs and the newbuild drillship, Deepwater Poseidon.

General and administrative expense was $52 million, compared with $47 million in the first quarter of 2018. The second quarter was impacted by un-forecasted charges, including $7 million related to the early retirement of certain personnel.

Depreciation expense was $211 million, up from $202 million in the first quarter of 2018. The increase was primarily due to the acquisition of Songa.

Interest expense, net of amounts capitalized, was $148 million, compared with $147 million in the prior quarter. Capitalized interest sequentially decreased $6 million to $7 million primarily due to the commencement of operations of the Deepwater Poseidon. Interest income was $13 million, compared with $12 million in the prior quarter.

The Effective Tax Rate⁽²⁾ was (8.0) percent, up from (42.2) percent in the prior quarter. The increase was primarily due to impairment losses in jurisdictions with no tax benefit. Also, the second quarter of 2018 included estimated transition taxes associated with the U.S. tax reform (“2017 Tax Act”). This estimate was partly offset by changes in the utilization of U.S. foreign tax credits. The Effective Tax Rate excluding discrete items⁽³⁾ was 22.0 percent, compared with (42.8) percent in the previous quarter.

Cash flows from operating activities were $3 million, compared with $103 million in the prior quarter. The decrease was largely associated with increased interest payments, as well as income tax payments partly related to the aforementioned transition taxes.

Second quarter 2018 capital expenditures were $39 million, compared with $53 million in the previous quarter. Additionally, during the second quarter, the company acquired a 33% interest in the newbuild, harsh environment semisubmersible Transocean Norge through a joint venture with Hayfin, with an initial investment of $91 million.

“Operationally, we delivered another solid quarter, with an Adjusted Normalized EBITDA margin of 40% on Adjusted Normalized Revenue of $783 million, representing a 21% sequential increase,” said President and Chief Executive Officer, Jeremy Thigpen. “This performance was driven by strong revenue efficiency, exceeding 97 percent, and increased activity, as the second quarter marked the first full quarter of operations for all five of our newest ultra-deepwater drillships, as well as the four recently acquired CAT-D harsh environment semisubmersibles from Songa.”

“During the quarter, we continued to high-grade our fleet, acquiring a 33% interest in the newbuild, harsh environment semisubmersible Transocean Norge, while retiring four, less competitive floaters.”

“We also further strengthened our balance sheet and extended our liquidity runway by negotiating a new $1 billion revolving credit facility extending into 2023, refinancing debt associated with the Songa acquisition, and executing on a secured facility for the Deepwater Pontus.”

Thigpen concluded: “Our industry-leading floater fleet, consistently strong operating performance, solid liquidity position, and enviable backlog, which includes several new contracts approximating $400 million, positions us well at a time when our optimism about the market’s recovery is growing.”

Non-GAAP Financial Measures

We present our operating results in accordance with accounting principles generally accepted in the U.S. (U.S. GAAP). We believe certain financial measures, such as Adjusted Net Income, EBITDA, Adjusted EBITDA and Adjusted Normalized EBITDA, which are non-GAAP measures, provide users of our financial statements with supplemental information that may be useful in evaluating our operating performance. We believe that such non-GAAP measures, when read in conjunction with our operating results presented under U.S. GAAP, can be used to better assess our performance from period to period and relative to performance of other companies in our industry, without regard to financing methods, historical cost basis or capital structure. Such non-GAAP measures should be considered as a supplement to, and not as a substitute for, financial measures prepared in accordance with U.S. GAAP.

Effective Tax Rate, excluding discrete items ⁽⁴⁾		22.0		%		(42.8	)	%		74.0		%		(32.5	)	%		78.0		%


⁽¹⁾ Our estimates change as we file tax returns, settle disputes with tax authorities or become aware of other events and include changes in
(a) deferred taxes, (b) valuation allowances on deferred taxes and (c) other tax liabilities.

⁽²⁾ The three months ended June 30, 2018 includes $18 million of additional tax benefit reflecting the catch-up effect of a decrease
in the annual effective tax rate from the previous quarter estimate.

⁽³⁾ Our effective tax rate is calculated as income tax expense divided by income before income taxes.

⁽⁴⁾ Our effective tax rate, excluding discrete items, is calculated as income tax expense, excluding various discrete items (such as changes
in estimates and tax on items excluded from income before income taxes), divided by income before income tax expense, excluding
gains and losses on sales and similar items pursuant to the accounting standards for income taxes and estimating the annual effective tax rate.
