1. Organization and Summary of Significant Accounting Policies | |||||||||
Organization | |||||||||
The Ridgewood Energy X Fund, LLC (the "Fund"), a Delaware limited liability company, was formed on August 30, 2007 and operates pursuant to a limited liability company agreement (the "LLC Agreement") dated as of January 2, 2008 by and among Ridgewood Energy Corporation (the "Manager") and the shareholders of the Fund, which addresses matters such as the authority and voting rights of the Manager and shareholders, capitalization, transferability of membership interests, participation in costs and revenues, distribution of assets and dissolution and winding up. The Fund was organized to primarily acquire interests in oil and gas properties located in the United States offshore waters of Texas, Louisiana, and Alabama in the Gulf of Mexico. | |||||||||
The Manager has direct and exclusive control over the management of the Fund's operations. With respect to project investments, the Manager locates potential projects, conducts due diligence and negotiates and completes the transactions in which the investments are made. The Manager performs, or arranges for the performance of, the management, advisory and administrative services required for Fund operations. Such services include, without limitation, the administration of shareholder accounts, shareholder relations and the preparation, review and dissemination of tax and other financial information. In addition, the Manager provides office space, equipment and facilities and other services necessary for Fund operations. The Manager also engages and manages the contractual relations with unaffiliated custodians, depositories, accountants, attorneys, broker-dealers, corporate fiduciaries, insurers, banks and others as required. See Notes 4 and 5. | |||||||||
Use of Estimates | |||||||||
The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. On an ongoing basis, the Manager reviews its estimates, including those related to the fair value of financial instruments, property balances, determination of proved reserves, impairments and asset retirement obligations. Actual results may differ from those estimates. | |||||||||
Fair Value Measurements | |||||||||
The fair value measurement guidance provides a hierarchy that prioritizes and defines the types of inputs used to measure fair value. The fair value hierarchy gives the highest priority to Level 1 inputs, which consists of unadjusted quoted prices for identical instruments in active markets. Level 2 inputs consist of quoted prices for similar instruments. Level 3 valuations are derived from inputs that are significant and unobservable; hence, these valuations have the lowest priority. Cash and cash equivalents and held-to-maturity investments approximate fair value based on Level 1 inputs. | |||||||||
Cash and Cash Equivalents | |||||||||
All highly liquid investments with maturities, when purchased, of three months or less, are considered cash and cash equivalents. At times, deposits may be in excess of federally insured limits, which are $250 thousand per insured financial institution. At December 31, 2013, the Fund's bank balances exceeded federally insured limits by $16.2 million. | |||||||||
Investments in Marketable Securities | |||||||||
At times, the Fund may invest in U.S. Treasury bills and notes. These investments are considered short-term when their maturities are one year or less, and long-term when their maturities are greater than one year. At December 31, 2012, the Fund had investments in marketable securities that were classified as held-to-maturity, which matured in June 2013. Held-to-maturity investments are those securities that the Fund has the ability and intent to hold until maturity, and are recorded at cost plus accrued income, adjusted for the amortization of premiums and discounts, which approximates fair value. For all investments, interest income is accrued as earned and amortization of premium or discount, if any, is included in interest income. | |||||||||
Salvage Fund | |||||||||
The Fund deposits in a separate interest-bearing account, or salvage fund, money to provide for the dismantling and removal of production platforms and facilities and plugging and abandoning its wells at the end of their useful lives in accordance with applicable federal and state laws and regulations. At December 31, 2012, the Fund had investments in U.S. Treasury securities within its salvage fund that were classified as held-to-maturity totaling $1.1 million, which matured in June 2013 and August 2013. There were no held-to-maturity investments at December 31, 2013. Interest earned on the account will become part of the salvage fund. There are no restrictions on withdrawals from the salvage fund. | |||||||||
Oil and Gas Properties | |||||||||
The Fund invests in oil and gas properties, which are operated by unaffiliated entities that are responsible for drilling, administering and producing activities pursuant to the terms of the applicable operating agreements with working interest owners. The Fund's portion of exploration, drilling, operating and capital equipment expenditures is billed by operators. | |||||||||
Exploration, development and acquisition costs are accounted for using the successful efforts method. Costs of acquiring unproved and proved oil and natural gas leasehold acreage, including lease bonuses, brokers' fees and other related costs are capitalized. Costs of drilling and equipping productive wells and related production facilities are capitalized. Costs of developing production facilities and pipelines that service multiple oil and gas properties are segregated as "Equipment and facilities - in progress." Exploratory costs are capitalized pending determination of whether proved reserves have been found. If proved commercial reserves are not found, exploratory drilling costs are expensed as dry-hole costs. Annual lease rentals and exploration expenses are expensed as incurred. All costs related to production activity and workover efforts are expensed as incurred. | |||||||||
Upon the sale, retirement or abandonment of a property, the cost and related accumulated depletion, depreciation and amortization, if any, is eliminated from the property accounts, and the resultant gain or loss is recognized. | |||||||||
At December 31, 2013 and 2012, amounts recorded in due to operators totaling $0.2 million related to capital expenditures for oil and gas properties. | |||||||||
Advances to Operators for Working Interests and Expenditures | |||||||||
The Fund's acquisition of a working interest in a well or a project requires it to make a payment to the seller for the Fund's rights, title and interest. The Fund may be required to advance its share of estimated cash expenditures for the succeeding month's operation. The Fund accounts for such payments as advances to operators for working interests and expenditures. As drilling costs are incurred, the advances are reclassified to unproved or proved properties. | |||||||||
Asset Retirement Obligations | |||||||||
For oil and gas properties, there are obligations to perform removal and remediation activities when the properties are retired. When a project reaches drilling depth and is determined to be either proved or dry, an asset retirement obligation is incurred. Plug and abandonment costs associated with unsuccessful projects are expensed as dry-hole costs. The following table presents changes in asset retirement obligations for the years ended December 31, 2013 and 2012. | |||||||||

Balance, end of year | $ | 1,513 | $ | 771 | |||||
As indicated above, the Fund maintains a salvage fund to provide for the funding of future asset retirement obligations. | |||||||||
Syndication Costs | |||||||||
Syndication costs are direct costs incurred by the Fund in connection with the offering of the Fund's shares, including professional fees, selling expenses and administrative costs payable to the Manager, an affiliate of the Manager and unaffiliated broker-dealers, which are reflected on the Fund's balance sheet as a reduction of shareholders' capital. | |||||||||
Revenue Recognition and Imbalances | |||||||||
Oil and gas revenues are recognized when oil and gas is sold to a purchaser at a fixed or determinable price, when delivery has occurred and title has transferred, and if collectability of the revenue is probable. The Fund uses the sales method of accounting for gas production imbalances. The volumes of gas sold may differ from the volumes to which the Fund is entitled based on its interests in the properties. These differences create imbalances that are recognized as a liability only when the properties' estimated remaining reserves net to the Fund will not be sufficient to enable the underproduced owner to recoup its entitled share through production. The Fund's recorded liability, if any, would be reflected in other liabilities. No receivables are recorded for those wells where the Fund has taken less than its share of production. | |||||||||
Derivative Instruments | |||||||||
The Fund may periodically utilize derivative instruments to manage the price risk attributable to its oil and gas production. Derivative instruments are carried on the balance sheet at fair value and recorded as either an asset or liability. Changes in the fair value of the derivatives are recorded currently in earnings unless specific hedge accounting criteria are met. At this time, the Fund has elected not to use hedge accounting for its derivatives and, accordingly, the derivatives are marked-to-market each quarter with fair value gains and losses recognized currently as other income on the statement of operations. The estimated fair value of such contracts is based upon various factors, including reported prices on the New York Mercantile Exchange ("NYMEX") and the Intercontinental Exchange ("ICE"), volatility, and the time value of options. The Fund recognizes all unrealized and realized gains and losses related to these contracts on a mark-to-market basis on the statement of operations within other income or loss. The related cash flow impact of the derivative activities are reflected as cash flows from operating activities on the statement of cash flows. The Fund actively monitors the creditworthiness of each counterparty and assesses the impact, if any, on its derivative positions. See Note 2. "Derivative Instruments". | |||||||||
Impairment of Long-Lived Assets | |||||||||
The Fund reviews the value of its oil and gas properties whenever management determines that events and circumstances indicate that the recorded carrying value of properties may not be recoverable. Impairments of proved properties are determined by comparing future net undiscounted cash flows to the net book value at the time of the review. If the net book value exceeds the future net undiscounted cash flows, the carrying value of the property is written down to fair value, which is determined using net discounted future cash flows from the property. The Fund provides for impairments on unproved properties when it determines that the property will not be developed or a permanent impairment in value has occurred. The fair value determinations require considerable judgment and are sensitive to change. Different pricing assumptions, reserve estimates or discount rates could result in a different calculated impairment. Given the volatility of oil and natural gas prices, it is reasonably possible that the Fund's estimate of discounted future net cash flows from proved oil and natural gas reserves could change in the near term. If oil and natural gas prices decline significantly, even if only for a short period of time, it is possible that write-downs of oil and gas properties could occur. | |||||||||
Depletion, Depreciation and Amortization | |||||||||
Depletion, depreciation and amortization of the cost of proved oil and gas properties are calculated using the units-of-production method. Proved developed reserves are used as the base for depleting capitalized costs associated with successful exploratory well costs, development costs and related facilities. The sum of proved developed and proved undeveloped reserves is used as the base for depleting or amortizing leasehold acquisition costs. In certain circumstances, equipment and facilities costs are depreciated over the estimated useful life of the asset. | |||||||||
Income Taxes | |||||||||
No provision is made for income taxes in the financial statements. The Fund is a limited liability company, and as such, the Fund's income or loss is passed through and included in the tax returns of the Fund's shareholders. | |||||||||
Income and Expense Allocation | |||||||||
Profits and losses are allocated to shareholders and the Manager in accordance with the LLC agreement. | |||||||||
Distributions | |||||||||
Distributions to shareholders are allocated in proportion to the number of shares held. The Manager determines whether available cash from operations, as defined in the LLC Agreement, will be distributed. Such distributions are allocated 85% to the shareholders and 15% to the Manager, as required by the LLC Agreement. | |||||||||
Available cash from dispositions, as defined in the LLC Agreement, will be paid 99% to shareholders and 1% to the Manager until the shareholders have received total distributions equal to their capital contributions. After shareholders have received distributions equal to their capital contributions, 85% of available cash from dispositions will be distributed to shareholders and 15% to the Manager. | |||||||||
Recent Accounting Pronouncements | |||||||||
The Fund has considered recent accounting pronouncements and believes that these recent pronouncements will not have a material effect on the Fund's financial statements. |

2. Derivative Instruments | |
The Fund periodically enters into derivative contracts relating to its oil or gas production. The use of such derivative instruments limits the downside risk of adverse price movements. The estimated fair value of such contracts is based upon various factors, including reported prices on NYMEX and ICE, volatility, and the time value of options. The Fund has exposure to credit risk to the extent the derivative instrument counterparty is unable to satisfy its settlement commitment. | |
The Fund had no derivative contracts during the year ended December 31, 2013. For the year ended December 31, 2012, the Fund's derivative instrument income consisted of realized losses of $59 thousand. |

Leasehold acquisition and exploratory drilling costs are capitalized pending determination of whether the well has found proved reserves. Unproved properties are assessed on a quarterly basis by evaluating and monitoring if sufficient progress is made on assessing the reserves.

Capitalized exploratory well costs are expensed as dry-hole costs in the event that reserves are not found or are not in sufficient quantities to complete the well and develop the field. At times, the Fund receives adjustments on certain wells from their respective operators upon review and audit of the wells' costs. Dry-hole costs of $1.9 million during the year ended December 31, 2013 were principally related to the Staurolite Project. Dry-hole costs of $61 thousand during the year ended December 31, 2012 were primarily related to the Dakota Project. | |||||||||

4. Related Parties | |
The LLC Agreement provides that the Manager render management, administrative and advisory services to the Fund. For such services, the Manager is paid an annual management fee, payable monthly, of 2.5% of total capital contributions, net of cumulative dry-hole and related well costs incurred by the Fund. Management fees for the years ended December 31, 2013 and 2012 were $1.3 million and $1.4 million, respectively. | |
The Manager is entitled to receive a 15% interest in cash distributions from operations made by the Fund. Distributions paid to the Manager for the years ended December 31, 2013 and 2012 were $0.8 million and $1.5 million, respectively. | |
At times, short-term payables and receivables, which do not bear interest, arise from transactions with affiliates in the ordinary course of business. | |
None of the amounts paid to the Manager have been derived as a result of arm's length negotiations. | |
The Fund has working interest ownership in certain projects to acquire and develop oil and natural gas projects with other entities that are likewise managed by the Manager. |

5. Commitments and Contingencies | |
Capital Commitments | |
The Fund has entered into multiple agreements for the acquisition, drilling and development of its investment properties. The estimated capital expenditures associated with these agreements vary depending on the stage of development on a property-by-property basis. As of December 31, 2013, the Fund expects to spend $5.3 million related to its investments in oil and gas properties, of which $1.5 million is expected to be spent during 2014. | |
Environmental Considerations | |
The exploration for and development of oil and natural gas involves the extraction, production and transportation of materials which, under certain conditions, can be hazardous or cause environmental pollution problems. The Manager and operators of the Fund's properties are continually taking action they believe appropriate to satisfy applicable federal, state and local environmental regulations and do not currently anticipate that compliance with federal, state and local environmental regulations will have a material adverse effect upon capital expenditures, results of operations or the competitive position of the Fund in the oil and gas industry. However, due to the significant public and governmental interest in environmental matters related to those activities, the Manager cannot predict the effects of possible future legislation, rule changes, or governmental or private claims. At December 31, 2013 and 2012, there were no known environmental contingencies that required the Fund to record a liability. | |
Effective October 22, 2012, the United States Department of Interior, acting through the Bureau of Safety and Environmental Enforcement, implemented the Final Drilling Safety Rule (the "Final Rule") which refined certain interim rules imposed in the immediate wake of the 2010 Deepwater Horizon oil spill. The Final Rule was promulgated for the prevention of waste and for the conservation of natural resources of the Outer Continental Shelf under the rulemaking authority of the Outer Continental Shelf Lands Act. The United States Congress continues to consider a number of legislative proposals relating to the upstream oil and gas industry both onshore and offshore, in addition to the Final Rule. Such proposals could result in significant additional laws or regulations governing the Fund's operations in the United States, including a proposal to raise or eliminate the cap on liability for oil spill cleanups under the Oil Pollution Act of 1990. Although it is not possible at this time to predict whether proposed legislation or regulations will be adopted as initially written, if at all, or how legislation or new regulation that may be adopted would impact the Fund's business, any such future laws and regulations could result in increased compliance costs or additional operating restrictions, which could have a material adverse effect on the Fund's operating results and cash flows. | |
Insurance Coverage | |
The Fund is subject to all risks inherent in the exploration for and development of oil and natural gas. Insurance coverage as is customary for entities engaged in similar operations is maintained, but losses may occur from uninsurable risks or amounts in excess of existing insurance coverage. The occurrence of an event that is not insured or not fully insured could have a material adverse impact upon earnings and financial position. Moreover, insurance is obtained as a package covering all of the funds managed by the Manager. Claims made by other funds managed by the Manager can reduce or eliminate insurance for the Fund. |

It is necessary to emphasize that the data presented should not be viewed as representing the expected cash flow from, or current value of, existing proved reserves as the computations are based on a number of estimates. Reserve quantities cannot be measured with precision and their estimation requires many judgmental determinations and frequent revisions. The required projection of production and related expenditures over time requires further estimates with respect to pipeline availability, rates and governmental control. Actual future prices and costs are likely to be substantially different from the current price and cost estimates utilized in the computation of reported amounts. Any analysis or evaluation of the reported amounts should give specific recognition to the computational methods utilized and the limitation inherent therein. | |||||||||||||||||

Organization and Summary of Significant Accounting Policies [Abstract] | ' | ||||||||
Use of Estimates | ' | ||||||||
Use of Estimates | |||||||||
The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expense during the reporting period. On an ongoing basis, the Manager reviews its estimates, including those related to the fair value of financial instruments, property balances, determination of proved reserves, impairments and asset retirement obligations. Actual results may differ from those estimates. | |||||||||
Fair Value Measurements | ' | ||||||||
Fair Value Measurements | |||||||||
The fair value measurement guidance provides a hierarchy that prioritizes and defines the types of inputs used to measure fair value. The fair value hierarchy gives the highest priority to Level 1 inputs, which consists of unadjusted quoted prices for identical instruments in active markets. Level 2 inputs consist of quoted prices for similar instruments. Level 3 valuations are derived from inputs that are significant and unobservable; hence, these valuations have the lowest priority. Cash and cash equivalents and held-to-maturity investments approximate fair value based on Level 1 inputs. | |||||||||
Cash and Cash Equivalents | ' | ||||||||
Cash and Cash Equivalents | |||||||||
All highly liquid investments with maturities, when purchased, of three months or less, are considered cash and cash equivalents. At times, deposits may be in excess of federally insured limits, which are $250 thousand per insured financial institution. At December 31, 2013, the Fund's bank balances exceeded federally insured limits by $16.2 million. | |||||||||
Investments in Marketable Securities | ' | ||||||||
Investments in Marketable Securities | |||||||||
At times, the Fund may invest in U.S. Treasury bills and notes. These investments are considered short-term when their maturities are one year or less, and long-term when their maturities are greater than one year. At December 31, 2012, the Fund had investments in marketable securities that were classified as held-to-maturity, which matured in June 2013. Held-to-maturity investments are those securities that the Fund has the ability and intent to hold until maturity, and are recorded at cost plus accrued income, adjusted for the amortization of premiums and discounts, which approximates fair value. For all investments, interest income is accrued as earned and amortization of premium or discount, if any, is included in interest income. | |||||||||
Salvage Fund | ' | ||||||||
Salvage Fund | |||||||||
The Fund deposits in a separate interest-bearing account, or salvage fund, money to provide for the dismantling and removal of production platforms and facilities and plugging and abandoning its wells at the end of their useful lives in accordance with applicable federal and state laws and regulations. At December 31, 2012, the Fund had investments in U.S. Treasury securities within its salvage fund that were classified as held-to-maturity totaling $1.1 million, which matured in June 2013 and August 2013. There were no held-to-maturity investments at December 31, 2013. Interest earned on the account will become part of the salvage fund. There are no restrictions on withdrawals from the salvage fund. | |||||||||
Oil and Gas Properties | ' | ||||||||
Oil and Gas Properties | |||||||||
The Fund invests in oil and gas properties, which are operated by unaffiliated entities that are responsible for drilling, administering and producing activities pursuant to the terms of the applicable operating agreements with working interest owners. The Fund's portion of exploration, drilling, operating and capital equipment expenditures is billed by operators. | |||||||||
Exploration, development and acquisition costs are accounted for using the successful efforts method. Costs of acquiring unproved and proved oil and natural gas leasehold acreage, including lease bonuses, brokers' fees and other related costs are capitalized. Costs of drilling and equipping productive wells and related production facilities are capitalized. Costs of developing production facilities and pipelines that service multiple oil and gas properties are segregated as "Equipment and facilities - in progress." Exploratory costs are capitalized pending determination of whether proved reserves have been found. If proved commercial reserves are not found, exploratory drilling costs are expensed as dry-hole costs. Annual lease rentals and exploration expenses are expensed as incurred. All costs related to production activity and workover efforts are expensed as incurred. | |||||||||
Upon the sale, retirement or abandonment of a property, the cost and related accumulated depletion, depreciation and amortization, if any, is eliminated from the property accounts, and the resultant gain or loss is recognized. | |||||||||
At December 31, 2013 and 2012, amounts recorded in due to operators totaling $0.2 million related to capital expenditures for oil and gas properties. | |||||||||
Advances to Operators for Working Interests and Expenditures | ' | ||||||||
Advances to Operators for Working Interests and Expenditures | |||||||||
The Fund's acquisition of a working interest in a well or a project requires it to make a payment to the seller for the Fund's rights, title and interest. The Fund may be required to advance its share of estimated cash expenditures for the succeeding month's operation. The Fund accounts for such payments as advances to operators for working interests and expenditures. As drilling costs are incurred, the advances are reclassified to unproved or proved properties. | |||||||||
Asset Retirement Obligations | ' | ||||||||
Asset Retirement Obligations | |||||||||
For oil and gas properties, there are obligations to perform removal and remediation activities when the properties are retired. When a project reaches drilling depth and is determined to be either proved or dry, an asset retirement obligation is incurred. Plug and abandonment costs associated with unsuccessful projects are expensed as dry-hole costs. The following table presents changes in asset retirement obligations for the years ended December 31, 2013 and 2012. | |||||||||

As indicated above, the Fund maintains a salvage fund to provide for the funding of future asset retirement obligations. | |||||||||
Syndication Costs | ' | ||||||||
Syndication Costs | |||||||||
Syndication costs are direct costs incurred by the Fund in connection with the offering of the Fund's shares, including professional fees, selling expenses and administrative costs payable to the Manager, an affiliate of the Manager and unaffiliated broker-dealers, which are reflected on the Fund's balance sheet as a reduction of shareholders' capital. | |||||||||
Revenue Recognition and Imbalances | ' | ||||||||
Revenue Recognition and Imbalances | |||||||||
Oil and gas revenues are recognized when oil and gas is sold to a purchaser at a fixed or determinable price, when delivery has occurred and title has transferred, and if collectability of the revenue is probable. The Fund uses the sales method of accounting for gas production imbalances. The volumes of gas sold may differ from the volumes to which the Fund is entitled based on its interests in the properties. These differences create imbalances that are recognized as a liability only when the properties' estimated remaining reserves net to the Fund will not be sufficient to enable the underproduced owner to recoup its entitled share through production. The Fund's recorded liability, if any, would be reflected in other liabilities. No receivables are recorded for those wells where the Fund has taken less than its share of production. | |||||||||
Derivative Instruments | ' | ||||||||
Derivative Instruments | |||||||||
The Fund may periodically utilize derivative instruments to manage the price risk attributable to its oil and gas production. Derivative instruments are carried on the balance sheet at fair value and recorded as either an asset or liability. Changes in the fair value of the derivatives are recorded currently in earnings unless specific hedge accounting criteria are met. At this time, the Fund has elected not to use hedge accounting for its derivatives and, accordingly, the derivatives are marked-to-market each quarter with fair value gains and losses recognized currently as other income on the statement of operations. The estimated fair value of such contracts is based upon various factors, including reported prices on the New York Mercantile Exchange ("NYMEX") and the Intercontinental Exchange ("ICE"), volatility, and the time value of options. The Fund recognizes all unrealized and realized gains and losses related to these contracts on a mark-to-market basis on the statement of operations within other income or loss. The related cash flow impact of the derivative activities are reflected as cash flows from operating activities on the statement of cash flows. The Fund actively monitors the creditworthiness of each counterparty and assesses the impact, if any, on its derivative positions. See Note 2. "Derivative Instruments". | |||||||||
Impairment of Long-Lived Assets | ' | ||||||||
Impairment of Long-Lived Assets | |||||||||
The Fund reviews the value of its oil and gas properties whenever management determines that events and circumstances indicate that the recorded carrying value of properties may not be recoverable. Impairments of proved properties are determined by comparing future net undiscounted cash flows to the net book value at the time of the review. If the net book value exceeds the future net undiscounted cash flows, the carrying value of the property is written down to fair value, which is determined using net discounted future cash flows from the property. The Fund provides for impairments on unproved properties when it determines that the property will not be developed or a permanent impairment in value has occurred. The fair value determinations require considerable judgment and are sensitive to change. Different pricing assumptions, reserve estimates or discount rates could result in a different calculated impairment. Given the volatility of oil and natural gas prices, it is reasonably possible that the Fund's estimate of discounted future net cash flows from proved oil and natural gas reserves could change in the near term. If oil and natural gas prices decline significantly, even if only for a short period of time, it is possible that write-downs of oil and gas properties could occur. | |||||||||
Depletion, Depreciation and Amortization | ' | ||||||||
Depletion, Depreciation and Amortization | |||||||||
Depletion, depreciation and amortization of the cost of proved oil and gas properties are calculated using the units-of-production method. Proved developed reserves are used as the base for depleting capitalized costs associated with successful exploratory well costs, development costs and related facilities. The sum of proved developed and proved undeveloped reserves is used as the base for depleting or amortizing leasehold acquisition costs. In certain circumstances, equipment and facilities costs are depreciated over the estimated useful life of the asset. | |||||||||
Income Taxes | ' | ||||||||
Income Taxes | |||||||||
No provision is made for income taxes in the financial statements. The Fund is a limited liability company, and as such, the Fund's income or loss is passed through and included in the tax returns of the Fund's shareholders. | |||||||||
Income and Expense Allocation | ' | ||||||||
Income and Expense Allocation | |||||||||
Profits and losses are allocated to shareholders and the Manager in accordance with the LLC agreement. | |||||||||
Distributions | ' | ||||||||
Distributions | |||||||||
Distributions to shareholders are allocated in proportion to the number of shares held. The Manager determines whether available cash from operations, as defined in the LLC Agreement, will be distributed. Such distributions are allocated 85% to the shareholders and 15% to the Manager, as required by the LLC Agreement. | |||||||||
Available cash from dispositions, as defined in the LLC Agreement, will be paid 99% to shareholders and 1% to the Manager until the shareholders have received total distributions equal to their capital contributions. After shareholders have received distributions equal to their capital contributions, 85% of available cash from dispositions will be distributed to shareholders and 15% to the Manager. | |||||||||
Recent Accounting Pronouncements | ' | ||||||||
Recent Accounting Pronouncements | |||||||||
The Fund has considered recent accounting pronouncements and believes that these recent pronouncements will not have a material effect on the Fund's financial statements. |
