STEINHAUSEN, Switzerland, Feb. 17, 2020 (GLOBE NEWSWIRE) -- Transocean Ltd. (NYSE: RIG) today reported net loss attributable to controlling interest of $51 million, $0.08 per diluted share, for the three months ended December 31, 2019.

Fourth quarter 2019 results included net favorable items of $212 million, or $0.35 per diluted share, as follows:

• $132 million, $0.22 per diluted share, gain on termination of construction contracts,
• $110 million, $0.18 per diluted share, related to discrete tax items; and
• $2 million, gain on disposal of assets.

These favorable items were partially offset by:

• $25 million, $0.04 per diluted share, loss on impairment of assets,
• $5 million, $0.01 per diluted share, in acquisition and restructuring costs; and
• $2 million, loss on retirement of debt.

After consideration of these net favorable items, fourth quarter 2019 adjusted net loss was $263 million, or $0.43 per diluted share.

Contract drilling revenues for the three months ended December 31, 2019, increased sequentially by $8 million, primarily due to rig reactivations, including of the ultra‑deepwater floaters Deepwater Mykonos and Deepwater Corcovado. The quarter was also favorably impacted by higher utilization on the rest of the company’s ultra‑deepwater fleet and a full quarter of revenues from the newbuild harsh environment floater Transocean Norge. These increases were partially offset by lower reimbursable revenue and lower revenue efficiency.

Fourth quarter 2019 results reflected a non-cash revenue reduction of $47 million, compared to $48 million in the third quarter, from contract intangible amortization associated with the Songa and Ocean Rig acquisitions.

Operating and maintenance expense was $575 million, compared with $547 million in the prior quarter. The sequential increase was the result of a full quarter of operations from the harsh environment floater Transocean Norge and higher concentration of maintenance expenses in the fourth quarter related to our capital spares program and in service fleet. This was partially offset by lower expenses reimbursed by our customers.

General and administrative expense was $54 million, up from $45 million in the third quarter of 2019. The increase was primarily due to legal, professional and advisory fees.

Interest expense, net of amounts capitalized, was $160 million, compared with $166 million in the prior quarter and capitalized interest was $10 million, unchanged from the prior quarter. Interest income was $10 million, compared with $11 million in the previous quarter.

The Effective Tax Rate⁽²⁾ was 30.3%, up from (6.9)% in the prior quarter. The increase was primarily due to releases of unrecognized tax benefits. The Effective Tax Rate excluding discrete items was (47.2)% compared to (37.5)% in previous quarter.

Cash flows provided by operating activities were $147 million, compared to $91 million in the prior quarter. The fourth quarter increase was primarily due to increased cash received from our unconsolidated affiliates for delivery and mobilization of Transocean Norge.

Fourth quarter 2019 capital expenditures of $128 million were related to the company’s maintenance capital which includes the reactivation of Deepwater Corcovado and Deepwater Mykonos and our newbuild drillships under construction. This compares with $121 million in the previous quarter.

“I would like to recognize, and thank, the entire Transocean team for once again delivering solid operating and financial results in the fourth quarter,” said President and Chief Executive Officer Jeremy Thigpen. “As utilization across our floating fleet improved for the first time in over five years, and dayrates for high‑specification ultra‑deepwater assets increased 75% over the course of the year, we believe that 2019 marked the beginning of the much-anticipated recovery in the offshore drilling industry.”

Thigpen added, “As a direct result of our strong performance in 2019, we generated almost $1 billion in adjusted EBITDA, which, when combined with the multiple financing transactions consummated throughout the year, further bolstered our liquidity position. This liquidity, coupled with our industry‑leading $10.2 billion backlog, provides us the financial stability to continue to invest in our people, the maintenance of our assets, and new technologies that will further differentiate us in the eyes of our customers and shareholders.”

“Looking forward, we are mindful of the risks COVID-19 presents to near-term oil demand, but believe that improving longer-term market fundamentals, along with an increasing list of opportunities, bodes well for a year-over-year increase in contracting activity, utilization and dayrates.”

Full Year 2019

For the year ended December 31, 2019, net loss attributable to controlling interest totaled $1.3 billion, or $2.05 per diluted share. Full year results included $368 million, or $0.60 per diluted share, net of unfavorable items listed as follows:

• $609 million, $0.99 per diluted share, loss on impairment, primarily for three floaters previously announced for retirement,
• $41 million, $0.07 per diluted share, loss on retirement of debt,
• $6 million, $0.01 per diluted share, in acquisition costs and restructuring; and
• $5 million, $0.01 per diluted share, loss on disposal of assets.

These unfavorable items were partially offset by:

• $150 million, $0.24 per diluted share, related to discrete tax items,
• $132 million, $0.22 per diluted share, gain on termination of construction contracts; and
• $11 million, $0.02 per diluted share, gain on bargain purchase.

After consideration of these net unfavorable items, adjusted net loss for 2019 was $887 million, or $1.45 per diluted share.

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 Contract Drilling Revenues, EBITDA, Adjusted EBITDA and Adjusted Net Income, 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.

(1) Average daily revenue is defined as contract drilling revenues earned per operating day. An operating day is defined as a calendar day during which a rig is contracted to earn a dayrate during the firm contract period after commencement of operations.
(2) Rig utilization is defined as the total number of operating days divided by the total number of available rig calendar days in the measurement period, expressed as a percentage.
(3) Revenue efficiency is defined as actual contract drilling revenues, excluding revenues for contract terminations and reimbursements, for the measurement period divided by the maximum revenue calculated for the measurement period, expressed as a percentage.  Maximum revenue is defined as the greatest amount of contract drilling revenues, excluding revenues for contract terminations and reimbursements, the drilling unit could earn for the measurement period, excluding amounts related to incentive provisions.

(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 December 31, 2019 included $30 million of additional tax expense, reflecting the cumulative effect of an increase 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 related to estimating the annual effective tax rate.
