| Significant Accounting Policies | |
| Principles of combination | (a) Principles of consolidation: The consolidated financial statements incorporate the financial statements of the Company and its wholly ‑owned subsidiaries. Income and expenses of subsidiaries acquired or disposed of during the period are included in the consolidated statements of operations from the effective date of acquisition and up to the effective date of disposal, as appropriate. All intercompany balances and transactions have been eliminated. |
| Use of estimates | (b) Use of estimates: The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. |
| Other comprehensive income/(loss) | (c) Other comprehensive income/(loss): The Company follows the accounting guidance relating to Comprehensive Income, which requires separate presentation of certain transactions that are recorded directly as components of stockholders’ equity. The Company has no other comprehensive income/(loss) and accordingly, comprehensive income/(loss) equals net income/(loss) for the periods presented and thus has not presented this in the statement of operations or in a separate statement. |
| Foreign currency translation | (d) Foreign currency translation: The functional currency of the Company is the U.S. Dollar. Foreign currency transactions are measured and recorded in the functional currency using the exchange rate in effect at the date of the transaction. As of balance sheet date, monetary assets and liabilities that are denominated in a currency other than the functional currency are adjusted to reflect the exchange rate at the balance sheet date and any gains or losses are included in the statement of operations. For the periods presented, the Company had no foreign currency derivative instruments. |
| Cash and cash equivalents | (e) Cash and cash equivalents: The Company considers highly liquid investments such as time deposits and certificates of deposit with an original maturity of three months or less to be cash equivalents. |
| Trade receivables (net) | (f) Trade receivables, net and accrued revenues: Trade receivables, net and accrued revenues, reflect receivables from vessel charters, net of an allowance for doubtful accounts. At each balance sheet date, all potentially uncollectible accounts are assessed individually for purposes of determining the appropriate provision for doubtful accounts. Provision for doubtful accounts for the periods presented was zero . |
| Inventories | (h) Inventories: Inventories consist of bunkers on board the vessels when vessels are unemployed or are operating under voyage charters and lubricants and stores on board the vessels. Inventories are stated at the lower of cost or market. Cost is determined by the first in, first out method. |
| Vessels | (i) Vessels, net: Vessels, net are stated at cost net of accumulated depreciation and impairment charges. The costs of the vessels acquired as part of a business acquisition are recorded at their fair value on the date of acquisition. The cost of vessels purchased consists of the contract price, less discounts, plus any direct expenses incurred upon acquisition, including improvements, commission paid, delivery expenses and other expenditures to prepare the vessel for her initial voyage. The initial purchase of LPG coolant for the refrigeration of cargo is also capitalized. Allocated interest costs incurred during construction are capitalized. Subsequent expenditures for conversions and major improvements are also capitalized when they appreciably extend the life, increase the earning capacity or improve the efficiency or safety of the vessels. Repairs and maintenance are expensed as incurred. |
| Impairment of long-lived assets | (j) Impairment of long ‑lived assets: The Company reviews their vessels “held and used” for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. When the estimate of future undiscounted cash flows, excluding interest charges, expected to be generated by the use of the asset is less than its carrying amount, the asset is evaluated for an impairment loss. Measurement of the impairment loss is based on the fair value of the asset. |
| Vessel depreciation | (k) Vessel depreciation: Depreciation is computed using the straight ‑line method over the estimated useful life of the vessels, after considering the estimated salvage value. Each vessel’s salvage value is equal to the product of its lightweight tonnage and estimated scrap rate. Management estimates the useful life of its vessels to be 25 years from the date of initial delivery from the shipyard. Second hand vessels are depreciated from the date of their acquisition through their remaining estimated useful life. |
| Drydocking and special survey costs | (l) Drydocking and special survey costs: Drydocking and special survey costs are accounted under the deferral method whereby the actual costs incurred are deferred and are amortized on a straight ‑line basis over the period through the date the next survey is scheduled to become due. We are required to drydock each of our vessels every five years until it reaches 15 years of age, after which we are required to drydock the applicable vessel every 2.5 years. Costs deferred are limited to actual costs incurred at the yard and parts used in the drydocking or special survey. Costs deferred include expenditures incurred relating to shipyard costs, hull preparation and painting, inspection of hull structure and mechanical components, steelworks, machinery works, and electrical works. If a survey is performed prior to the scheduled date, the remaining unamortized balances are immediately written off. Unamortized balances of vessels that are sold are written ‑off and included in the calculation of the resulting gain or loss in the period of the vessel’s sale. The amortization charge is presented within Depreciation and amortization in the consolidated statement of operations. |
| Financing costs | (m) Financing costs: Financing costs incurred for obtaining new loans and credit facilities are deferred and amortized to interest expense over the respective term of the loan or credit facility using the effective interest rate method. Any unamortized balance of costs relating to loans repaid or refinanced is expensed in the period the repayment or refinancing is made, subject to the accounting guidance regarding Debt—Modifications and Extinguishments. Any unamortized balance of costs related to credit facilities repaid is expensed in the period. Any unamortized balance of costs relating to credit facilities refinanced are deferred and amortized over the term of the respective credit facility in the period the refinancing occurs, subject to the provisions of the accounting guidance relating to Debt—Modifications and Extinguishments. The unamortized financing costs are reflected in Deferred charges in the accompanying consolidated balance sheet. |
| Revenue and expenses | (o) Revenues and expenses: Revenue is recognized when an agreement exists, the vessel is made available to the charterer or services are provided, the charter hire is determinable and collection of the related revenue is reasonably assured.
Net pool revenue: As from April 1, 2015, we began operation of a pool. Net pool revenues—related party for each vessel in the pool is determined in accordance with the profit sharing terms specified within the pool agreement. In particular, the pool manager calculates the net pool revenues using gross revenues less voyage expenses of all the pool vessels and less the general and administrative expenses of the pool and distributes the net pool revenues as time charter hire to participants based on:
·
pool points (vessel attributes such as cargo carrying capacity, fuel consumption, and speed are taken into consideration); and
·
number of days the vessel participated in the pool in the period.
We recognize net pool revenues—related party on a monthly basis, when the vessel has participated in the pool during the period and the amount of net pool revenues for the month can be estimated reliably.
Voyage charter revenue: Under a voyage charter, the revenues are recognized on a pro ‑rata basis over the duration of the voyage determined on a discharge—to discharge port basis but the Company does not begin recognizing revenue until a charter has been agreed to by the customer and the Company, even if the vessel has discharged its cargo and is sailing to the anticipated load port for its next voyage. In the event a vessel is acquired or sold while a voyage is in progress, the revenue recognized is based on an allocation formula agreed between the buyer and the seller. Demurrage income represents payments by the charterer to the vessel owner when loading or discharging time exceeds the stipulated time in the voyage charter and is recognized when earned and collection is reasonably assured. Despatch expense represents payments by the Company to the charterer when loading or discharging time is less than the stipulated time in the voyage charter and is recognized as incurred. Voyage charter revenue relating to voyages in progress as of the balance sheet date are accrued and presented in Trade receivables and accrued revenue in the accompanying consolidated balance sheet .
Time charter revenue: Time charter revenues are recorded ratably over the term of the charter as service is provided. Time charter revenues received in advance of the provision of charter service are recorded as deferred income and recognized when the charter service is rendered. Deferred income or accrued revenue also may result from straight ‑line revenue recognition in respect of charter agreements that provide for varying charter rates. Deferred income and accrued revenue amounts that will be recognized within the next twelve months are presented as current, with amounts to be recognized thereafter presented as non ‑current. Revenues earned through the profit sharing arrangements in the time charters represent contingent rental revenues that are recognized when earned and amounts are reasonably assured based on estimates provided by the charterer.
Commissions: Charter hire commissions to brokers or managers, if any, are deferred and amortized over the related charter period and are included in Voyage expenses.
Vessel operating expenses: Vessel operating expenses are accounted for as incurred on the accrual basis. Vessel operating expenses include crew wages and related costs, the cost of insurance, expenses relating to repairs and maintenance, the cost of spares and consumable stores and other miscellaneous expenses. |
| Repairs and maintenance | (p) Repairs and maintenance: All repair and maintenance expenses, including underwater inspection costs are expensed in the period incurred. Such costs are included in Vessel operating expenses. |
| Segment reporting | (s) Segment reporting: Each of the Company’s vessels serve the same type of customer, have similar operations and maintenance requirements, operate in the same regulatory environment, and are subject to similar economic characteristics. Based on this, the Company has determined that it operates in one reportable segment, the international transportation of liquid petroleum gas with its fleet of vessels. Furthermore, when the Company charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable. |
| Derivative Instruments | (t) Derivative instruments: All derivatives are stated at their fair value, as either a derivative asset or a liability. The fair value of the interest rate derivatives is based on a discounted cash flow analysis and their fair value changes are recognized in current period earnings. When the derivatives do qualify for hedge accounting, depending upon the nature of the hedge, changes in fair value of the derivatives are either recognized in current period earnings or in other comprehensive income/(loss) (effective portion) until the hedged item is recognized in the consolidated statements of operations. For the periods presented, no derivatives were accounted for as accounting hedges. |
| Fair value of financial instruments | (u) Fair value of financial instruments: In accordance with the requirements of accounting guidance relating to Fair Value Measurements, the Company classifies and discloses its assets and liabilities carried at fair value in one of the following three categories:
Level 1:
Quoted market prices in active markets for identical assets or liabilities.
Level 2:
Observable market based inputs or unobservable inputs that are corroborated by market data.
Level 3:
Unobservable inputs that are not corroborated by market data. |
| Recent accounting pronouncements | (v) Recent accounting pronouncements: In May 2014, the Financial Accounting Standards Board (“FASB”) amended its accounting guidance for revenue recognition. The fundamental principles of the new guidance are that companies should recognize revenue in a manner that reflects the timing of the transfer of services to customers and consideration that a company expects to receive for the services provided. It also requires additional disclosures necessary for the financial statement users to understand the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The standard is effective for annual periods beginning after December 15, 2017, and interim periods therein, and shall be applied either retrospectively to each period presented or as a cumulative effect adjustment as of the date of adoption, early adoption is permitted, but not before the beginning of 2017. We are currently assessing the impact the amended guidance will have on our financial statements.
In February 2015, the FASB issued accounting guidance amending consolidation analysis which focuses on the consolidation evaluation for reporting organizations that are required to evaluate whether they should consolidate certain legal entities. This new standard simplifies consolidation accounting by reducing the number of consolidation models and providing incremental benefits to stakeholders. In addition, the new standard places more emphasis on risk of loss when determining a controlling financial interest, reduces the frequency of the application of related-party guidance when determining a controlling financial interest in a variable interest entity (a “VIE”), and changes consolidation conclusion for public and private companies in several industries that typically make use of limited partnerships or VIEs. The pronouncement is effective prospectively for annual periods beginning after December 15, 2015, and interim periods within that reporting period. The amended guidance will have no impact on our financial statements.
In April 2015, an accounting pronouncement was issued by the FASB to update the guidance related to the presentation of debt issuance costs. This guidance requires debt issuance costs, related to a recognized debt liability, be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability rather than being presented as an asset. This pronouncement is effective retrospectively for fiscal years beginning after December 15, 2015 and interim periods within that reporting period, with early adoption permitted. We will adopt this pronouncement on April 1, 2016 and the amount of debt issuance costs that would be classified on our balance sheet as a reduction of debt was $23.7 million as of March 31, 2016 and $13.3 million as of March 31, 2015 .
In July 2015, the FASB issued accounting guidance requiring entities to measure most inventory at the lower of cost and net realizable value. The pronouncement is effective prospectively for annual periods beginning after December 15, 2016, and interim periods within that reporting period. We are currently assessing the impact the amended guidance will have on our financial statements.
In February 2016, the FASB issued accounting guidance to update the requirements of financial accounting and reporting for lessees and lessors. The updated guidance, for lease terms of more than 12 months, will require a dual approach for lessee accounting under which a lessee would account for leases as finance leases or operating leases. Both finance leases and operating leases will result in the lessee recognizing a right-of-use asset and a corresponding lease liability. For finance leases, the lessee would recognize interest expense and amortization of the right-of-use asset, and for operating leases, the lessee would recognize a straight-line total lease expense. Lessor accounting remains largely unchanged. The new standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The pronouncement is effective prospectively for public business entities for annual periods beginning after December 15, 2018, and interim periods within that reporting period. Early adoption is permitted for all entities. We are currently assessing the impact the amended guidance will have on our financial statements.
In March 2016, the FASB issued accounting guidance to simplify the requirements of accounting for share-based payment transactions. The guidance simplifies the accounting for taxes related to stock-based compensation, including adjustments to how excess tax benefits and an entity’s payments for tax withholdings should be classified. Additionally, an entity may make an entity-wide policy election to either estimate the number of awards that are expected to vest or account for forfeitures when they occur. The pronouncement is effective for annual periods beginning after December 15, 2016, and interim periods within that reporting period with early adoption permitted in any interim or annual period. We have early adopted this pronouncement for the year ended March 31, 2016 and have made the entity-wide policy election to account for forfeitures when they occur, which resulted in us recognizing an additional $0.1 million of stock-based compensation for the year ended March 31, 2016 . |

| Significant Accounting Policies | |
| Principles of combination | (a) Principles of combination: The accompanying combined financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and include the accounts and operating results of the legal entities comprising the Owning Companies as discussed in Note 1, which were all under common management. The combined statements represent an aggregation of the U.S. GAAP financial information of the entities comprising the Owning Companies. All intercompany balances and transactions have been eliminated upon combination. |
| Use of estimates | (b) Use of estimates: The preparation of the Predecessor combined financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. |
| Other comprehensive income/(loss) | (c) Other comprehensive income/(loss): The Company follows the accounting guidance relating to Comprehensive Income , which requires separate presentation of certain transactions that are recorded directly as components of stockholders’ equity. The Company has no other comprehensive income/(loss) and accordingly, comprehensive income/(loss) equals net income/(loss) for the periods presented. |
| Foreign currency translation | (d) Foreign currency translation: The functional currency of the Company is the U.S. Dollar. Each foreign currency transaction is measured and recorded in the functional currency using the exchange rate in effect at the date of the transaction. As of the balance sheet date, monetary assets and liabilities that are denominated in a currency other than the functional currency are adjusted to reflect the exchange rate at the balance sheet date and any gains or losses are included in the combined statement of operations. |
| Cash and cash equivalents | (e) Cash and cash equivalents: The Company considers highly liquid investments such as time deposits and certificates of deposit with an original maturity of three months or less to be cash equivalents. |
| Trade receivables (net) | (f) Trade receivables (net): Trade receivables (net), reflect receivables from vessel charters, net of an allowance for doubtful accounts. At each balance sheet date, all potentially uncollectible accounts are assessed individually for purposes of determining the appropriate provision for doubtful accounts. No allowance for doubtful accounts was recorded for the periods presented. |
| Inventories | (g) Inventories: Inventories consist of bunkers on board the vessels when vessels are unemployed or are operating under voyage charters and lubricants and stores on board the vessels. Inventories are stated at the lower of cost or market. Cost is determined by the first in, first out method. |
| Vessels | (h) Vessels: Vessels are stated at cost, less accumulated depreciation. The cost of the vessels consists of the contract price, less discounts, plus any direct expenses incurred upon acquisition, including improvements, commission paid, delivery expenses and other expenditures to prepare the vessel for her initial voyage. The cost of vessels constructed includes financing costs incurred during the construction period. Subsequent expenditures for conversions and major improvements are also capitalized when they appreciably extend the life, increase the earning capacity or improve the efficiency or safety of the vessels. Repairs and maintenance are expensed as incurred. |
| Impairment of long-lived assets | (i) Impairment of long ‑lived assets: The Company reviews their vessels “held and used” for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be recoverable. When the estimate of future undiscounted cash flows, excluding interest charges, expected to be generated by the use of the asset is less than its carrying amount, the asset is evaluated for an impairment loss. Measurement of the impairment loss is based on the fair value of the asset. In this respect, management regularly reviews the carrying amount of the vessels in connection with the estimated recoverable amount for each of the Company’s vessels. |
| Vessel depreciation | (j) Vessel depreciation: Depreciation is computed using the straight ‑line method over the estimated useful life of the vessels, after considering the estimated salvage value. Each vessel’s salvage value is equal to the product of its lightweight tonnage and estimated scrap rate, which is estimated to be $ 400 per lightweight ton. Management of the Owning Companies estimates the useful life of its vessels to be 20 years from the date of initial delivery from the shipyard for VLGC’s and 25 years for PGC vessels. Secondhand vessels are depreciated from the date of their acquisition through their remaining estimated useful life. |
| Drydocking and special survey costs | (k) Drydocking and special survey costs: Drydocking and special survey costs are accounted under deferral method whereby actual costs incurred are deferred and are amortized on a straight ‑line basis over the period through the date the next survey is scheduled to become due. We are required to drydock a vessel once every five years until it reaches 15 years of age, after which we are required to drydock the applicable vessel every two and one ‑half years. Costs deferred are limited to actual costs incurred at the yard and parts used in the drydocking or special survey. Costs deferred include expenditures incurred relating to shipyard costs, hull preparation and painting, inspection of hull structure and mechanical components, steelworks, machinery works, and electrical works. If a survey is performed prior to the scheduled date, the remaining unamortized balances are immediately written off. Unamortized balances of vessels that are sold are written ‑off and included in the calculation of the resulting gain or loss in the period of the vessel’s sale. The amortization charge is presented within “Depreciation and amortization” in the combined statements of operations. |
| Financing costs | (l) Financing costs: Financing fees incurred for obtaining new loans and credit facilities are deferred and amortized to interest expense over the respective loan or credit facility using the effective interest rate method. Any unamortized balance of costs relating to loans repaid or refinanced is expensed in the period the repayment or refinancing is made, subject to the accounting guidance regarding debt extinguishment. Any unamortized balance of costs related to credit facilities repaid is expensed in the period. Any unamortized balance of costs relating to credit facilities refinanced are deferred and amortized over the term of the respective credit facility in the period the refinancing occurs, subject to the provisions of the accounting guidance relating to debt extinguishment. The unamortized financing costs are reflected in Deferred Charges in the accompanying combined balance sheets. |
| Revenue and expenses | (m) Revenue and expenses: Revenue is recognized when an agreement exists, the vessel is made available to the charterer or services are provided, the charter hire is determinable and collection of the related revenue is reasonably assured.
Time charter revenue: Time charter revenues are recorded ratably over the term of the charter as service is provided. Time charter revenues received in advance of the provision of charter service are recorded as deferred income and recognized when the charter service is rendered. Accrued revenue results from straight ‑line revenue recognition in respect of charter agreements that provide for varying charter rates. Deferred income and accrued revenue amounts that will be recognized within the next twelve months are presented as current, with amounts to be recognized thereafter presented as non ‑current. Revenues earned through the profit sharing arrangements in the time charters represent contingent rental revenues that are recognized when earned and amounts are reasonably assured based on estimates provided by the charterer.
Voyage charter revenue: Under a voyage charter, the revenues are recognized on a pro ‑rata basis over the duration of the voyage determined on a discharge-to-discharge port basis but the Company does not begin recognizing revenue until a charter has been agreed to by the customer and the Company, even if the vessel has discharged its cargo and is sailing to the anticipated load port for its next voyage. In the event a vessel is sold while a voyage is in progress, the revenue recognized is based on an allocation formula agreed between the buyer and the seller. Demurrage income represents payments by the charterer to the vessel owner when loading or discharging time exceeds the stipulated time in the voyage charter and is recognized when earned and collection is reasonably assured. Despatch expense represents payments by the Company to the charterer when loading or discharging time is less than the stipulated time in the voyage charter and is recognized as incurred.
Commissions: Charter hire commissions to brokers or the Manager are deferred and amortized over the related charter period and are included in Voyage expenses.
Vessel operating expenses: Vessel operating expenses are accounted for as incurred on the accrual basis. Vessel operating expenses include crew wages and related costs, the cost of insurance, expenses relating to repairs and maintenance, the cost of spares and consumable stores, and other miscellaneous expenses. |
| Repairs and maintenance | (n) Repairs and maintenance: All repair and maintenance expenses, including underwater inspection costs are expensed in the period incurred. Such costs are included in Vessel operating expenses. |
| Segment reporting | (o) Segment reporting: Each of the Owning Company’s vessels serve the same type of customer, have similar operations and maintenance requirements, operate in the same regulatory environment, and are subject to similar economic characteristics. Based on this, the Company has determined that it operates in one reportable segment, the international transportation of liquid petroleum gas with its fleet of vessels. Furthermore, when the Company charters a vessel to a charterer, the charterer is free to trade the vessel worldwide and, as a result, the disclosure of geographic information is impracticable. |
| Derivative Instruments | (p) Derivative Instruments: The Company enters into interest rate swap agreements to manage its exposure to fluctuations of interest rate risk associated with its borrowings. All derivatives are recognized in the combined financial statements at their fair value, as either a derivative asset or a liability. The fair value of the interest rate derivatives is based on a discounted cash flow analysis. When such derivatives do not qualify for hedge accounting, the Company recognizes their fair value changes in current period earnings. |
| Fair value of financial instruments | (q) Fair value of financial instruments: In accordance with the requirements of accounting guidance relating to Fair Value Measurements, the Company classifies and discloses its assets and liabilities carried at fair value in one of the following three categories:
Level 1:
Quoted market prices in active markets for identical assets or liabilities
Level 2:
Observable market based inputs or unobservable inputs that are corroborated by market data
Level 3:
Unobservable inputs that are not corroborated by market data. |
| Recent accounting pronouncements | (r) Recent accounting pronouncements: There are no recent accounting pronouncements the adoption of which would have a material effect on the Company’s combined financial statements in the current period or expected to have an impact on future periods. |
