Transocean Ltd. Reports Third Quarter 2017 Results

Transocean Ltd. (NYSE:RIG) today reported net loss attributable to controlling interest of $1.417 billion, $3.62 per diluted share, for the three months ended September 30, 2017.

Third quarter 2017 results included net unfavorable items of $1.481 billion, or $3.78 per diluted share as follows:

$1.386 billion, $3.54 per diluted share, loss on impairment associated with the previously announced retirement of six floaters;
$90 million, $0.23 per diluted share, in discrete tax expense; and
$5 million, $0.01 per diluted share, for acquisition costs related to Songa Offshore and other items.

After consideration of these net unfavorable items, third quarter 2017 adjusted net income was $64 million, or $0.16 per diluted share.

Contract drilling revenues for the three months ended September 30, 2017, decreased $6 million sequentially to $699 million. Fleet utilization improved to 52 percent, compared with 44 percent in the prior quarter, reflecting the positive impact of the warm-stacked reactivation of the ultra-deepwater floaters, the Deepwater Asgard and Development Driller III, and the harsh environment semisubmersible Transocean Barents. The increase in activity was partially offset by the divestiture of the company’s jackup fleet in the second quarter of 2017.

Other revenues were $109 million, compared with $46 million in the prior quarter. The third quarter of 2017 included $87 million awarded to the company in connection with a customer-terminated drilling contract in 2015.

Operating and maintenance expense was $323 million, including $6 million in reimbursements related to the aforementioned award. The third quarter of 2017 was lower than anticipated due to the timing of certain maintenance expenses, contract preparation costs, and recycling costs associated with the previously announced retirements. The quarter was also favorably impacted by the company’s ongoing cost control initiatives. This compares with $333 million in the prior quarter, which included $4 million in unfavorable items associated with litigation matters and restructuring charges.

General and administrative expense was $39 million, up from $35 million in the second quarter of 2017. The increase was due largely to acquisition costs related to Songa Offshore.

Depreciation expense was $197 million, down from $219 million in the second quarter of 2017. The decrease was primarily due to the sale of the jackup fleet in the second quarter of 2017.

Interest expense, net of amounts capitalized, was $112 million, compared with $129 million in the prior quarter. The decrease was largely due to the company’s recent debt capital markets transactions. Capitalized interest was $31 million in third quarter of 2017, compared with $30 million in the prior quarter. Interest income increased $14 million sequentially to $21 million. The increase was almost entirely due to interest related to the aforementioned award.

The Effective Tax Rate(2) was (14.7) percent, down from 2.2 percent in the prior quarter. The decrease in the rate was primarily due to an increase in the company’s U.S. deferred tax asset valuation allowance and current-year losses on impairment and disposal of assets. The Effective Tax Rate excluding discrete items(3) was 56.5 percent, compared with 74.0 percent in the previous quarter. For the three months ended September 30, 2017, the company’s income tax expense was $180 million, which includes $137 million of non‑cash items relating to a valuation allowance on certain deferred tax assets.

Cash flows from operating activities increased $65 million sequentially to $384 million primarily due to the aforementioned award.

Third quarter 2017 capital expenditures of $128 million were primarily related to the company’s contracted newbuild drillships. This compares with $136 million in the previous quarter.

“Despite the challenging environment, we continue to operate at a high level, delivering another quarter in which Revenue Efficiency exceeded 97% and Adjusted Normalized EBITDA margin approached 50%,” said Jeremy Thigpen, President and Chief Executive Officer. “In addition to the strong operating results, during the quarter, we continued the high-grading of our fleet by announcing our intent to acquire Songa Offshore, which includes the addition of four new, high-specification, harsh environment semisubmersibles. We also announced our decision to recycle six additional floaters, further improving the overall quality and competitiveness of our fleet.”

Thigpen added: “During October, we issued $750 million of senior unsecured debt with the intent of retiring our near-dated maturities. This action, coupled with cash flow from operations of $384 million, and the anticipated incremental backlog of approximately $4 billion attributable to the Songa Offshore transaction, further extends our liquidity runway, and positions us well for a market recovery.”

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.

(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 for the measurement period divided by the maximum revenue calculation for the measurement period, expressed as a percentage. Maximum revenue is defined as the greatest amount of contract drilling revenues 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 and nine months ended September 30, 2017 includes $(13) million of additional tax expense (benefit) reflecting the catch-up effect of an increase (decrease) in the annual effective tax rate from the previous quarter estimate.

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

(4) Our effective tax rate, excluding discrete items, is calculated as income tax expense for continuing operations, excluding various discrete items (such as changes in estimates and tax on items excluded from income before income taxes), divided by income from continuing operations 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.
