Significant Accounting Policies | SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The preparation of the consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes, including the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. Actual results could differ from those estimates. Cash and Cash Equivalents The Company considers all cash and short term liquid investments with original maturities of 90 days or less to be cash and cash equivalents. The cash balances of the Company are held in multiple financial institutions. At times, cash and cash equivalent balances at certain banks and financial institutions may exceed insurable amounts. The Company believes it mitigates this risk by monitoring the financial stability of institutions holding material cash balances. The Company has not experienced any losses in such accounts and believes that the risk of loss is minimal. Restricted Cash Restricted cash primarily relates to cash held in escrow to fund future development costs and refundable customer deposits held in escrow. Accounts Receivable and Allowance for Doubtful Accounts Accounts receivable represent amounts due from customers and third parties originating during the normal course of business. As of December 31, 2016 and 2015 , all amounts are considered fully collectible and no allowance for doubtful accounts is recorded. The allowance for doubtful accounts is estimated based on our historical losses, the existing economic conditions, and the financial stability of our customers. Receivables are written-off in the period that they are deemed uncollectible. Inventory and Cost of Sales Inventory consists of land in the process of development, undeveloped land, developed lots, completed homes, raw land scheduled for development, and land not owned under option agreements in Texas and Georgia. Inventory is valued at cost unless the carrying value is determined to be not recoverable in which case the affected inventory is written down to fair value. Cost includes any related pre-acquisition costs that are directly identifiable with a specific property so long as those pre-acquisition costs are recoverable at the sale of the property. Residential lots held for sale and lots held for development include the initial cost of acquiring the land as well as certain costs capitalized related to developing the land into individual residential lots including direct overhead, interest and real estate taxes. Land, development and other project costs, including direct overhead, interest and property taxes incurred during development and home construction, are capitalized. Land development and other common costs that benefit an entire community are allocated to individual lots or homes based on relative sales value. The costs of lots are transferred to work in progress when home construction begins. Home construction costs and related carrying charges (principally interest and property taxes) are allocated to the cost of individual homes using the specific identification method. Inventory costs for completed homes are expensed as cost of sales as homes are sold. Changes to estimated total development costs subsequent to initial home closings in a community are generally allocated to the unsold homes in the community on a pro-rata basis. The life cycle of a community generally ranges from two to six years, commencing with the acquisition of land, continuing through the land development phase, construction, and concluding with the sale and delivery of homes. As of December 31, 2016 2015 Completed home inventory and residential lots held for sale $ 127,679 $ 85,342 Work in process 269,255 236,383 Undeveloped land 4,070 6,193 Land not owned under option agreements 9,293 16,214 Total Inventory $ 410,297 $ 344,132 Impairment of Real Estate Inventory In accordance with the ASC Topic 360, Property, Plant, and Equipment , we evaluate our real estate inventory for indicators of impairment by individual community and development during each reporting period. For our builder operations segment, due largely to the relatively short construction periods of homes (generally ranging from five to nine months) in the communities, our growth over the past four years , and the favorable conditions of the housing market since 2011, we have not experienced any circumstances during the years ended December 31, 2016 , 2015 and 2014 that are indicators of potential impairment within our builder operations segment. During each reporting period, community gross margins are reviewed by management. In the event that inventory in an individual community is moving at a slower than anticipated absorption pace or the average sales prices or margins within an individual community are trending downward and are anticipated to continue to trend downward over the life of the community, the Company will further investigate these communities and evaluate them for impairment. For our land development segment, we perform a quarterly review for indicators of impairment for each project which involves projecting future lot sales based on executed contracts and comparing these revenues to projected costs. In determining the allocation of costs to a particular land parcel, we rely on project budgets that are based on a variety of assumptions, including assumptions about schedules and future costs to be incurred. It is common that actual results differ from budgeted amounts for various reasons, including delays, increases in costs that have not been committed, unforeseen issues encountered during project development that fall outside the scope of existing contracts, or items that ultimately cost more or less than the budgeted amount. While the actual results for a particular project are accurately reported over time, a variance between the budget and actual costs could occur. To reduce the potential for such variances, we apply procedures on a consistent basis, including assessing and revising project budgets on a periodic basis, obtaining commitments from subcontractors and vendors for future costs to be incurred and utilizing the most recent information available to estimate costs. Each reporting period, the Company reviews our real estate assets to determine whether the estimated remaining future cash flows of the development are more or less than the asset’s carrying value. The estimated cash flows are determined by projecting the remaining sales revenue from lot sales based on the contractual lot takedowns remaining or historical/projected home sales/delivery absorptions for homebuilding operations and then comparing that to the remaining projected expenditures for development or home construction. Remaining projected expenditures are based on the most current pricing/bids received from subcontractors for current phases or homes under development. For future phases of land development, management uses its best judgment to project potential cost increases. When projecting sales revenue, management does not assume improvement in market conditions. If the estimated cash flows are more than the asset’s carrying value, no impairment adjustment is required. However, if the estimated cash flows are less than the asset’s carrying value, the asset is deemed impaired and will be written down to fair value. These impairment evaluations require us to make estimates and assumptions regarding future conditions, including the timing and amounts of development costs and sales prices of real estate assets, to determine if expected future cash flows will be sufficient to recover the asset’s carrying value. Fair value is determined based on estimated future cash flows discounted for inherent risks associated with real estate assets. These discounted cash flows are impacted by expected risk based on estimated land development activities, construction and delivery timelines, market risk of price erosion, uncertainty of development or construction cost increases, and other risks specific to the asset or market conditions where the asset is located when assessment is made. These factors are specific to each community and may vary among communities. When estimating cash flows of a community, the Company makes various assumptions, including: (i) expected sales prices and sales incentives to be offered, including the number of homes available, pricing and incentives being offered by us or other builders in other communities, and future sales price adjustments based on market and economic trends; (ii) expected sales pace and cancellation rates based on local housing market conditions, competition and historical trends; (iii) costs expended to date and expected to be incurred including, but not limited to, land and land development costs, home construction costs, interest costs, indirect construction and overhead costs, and selling and marketing costs; (iv) alternative product offerings that may be offered that could have an impact on sales pace, sales price and/or building costs; and (v) alternative uses for the property. Many assumptions are interdependent and a change in one may require a corresponding change to other assumptions. For example, increasing or decreasing sales absorption rates has a direct impact on the estimated per unit sales price of a home, the level of time-sensitive costs (such as indirect construction, overhead and carrying costs), and selling and marketing costs (such as model maintenance costs and advertising costs). Due to uncertainties in the estimation process, the significant volatility in demand for new housing and the long life cycle of many communities, actual results could differ significantly from such estimates. For the years ended December 31, 2016 , 2015 and 2014 , the Company has not identified any indicators of impairment or changes in circumstances that may indicate that the carrying amount of an asset may be impaired. Capitalization of Interest The Company capitalizes interest costs incurred to inventory during active development and other qualifying activities. Interest capitalized as cost of inventory is charged to cost of sales as related homes, land and/or lots are closed. Interest incurred on undeveloped land is directly expensed and included in interest expense in our consolidated statements of income. Interest costs incurred, capitalized and expensed were as follows (in thousands): 2016 2015 2014 Interest capitalized at beginning of year $ 9,085 $ 3,713 $ 1,065 Interest incurred 3,218 9,625 4,146 Interest charged to cost of sales (2,886 ) (3,972 ) (105 ) Interest charged to interest expense — (281 ) (1,393 ) Interest capitalized at end of year $ 9,417 $ 9,085 $ 3,713 Earnest Money Deposits The Company accounts for variable interest entities in accordance with ASC Topic 810, Consolidation (“ASC 810”). Under ASC 810, an entity is a variable interest entity (“VIE”) when: (a) the equity investment at risk in the entity is not sufficient to permit the entity to finance its activities without additional subordinated financial support provided by other parties, including the equity holders; (b) the entity’s equity holders as a group either (i) lack the direct or indirect ability to make decisions about the entity, (ii) are not obligated to absorb expected losses of the entity or (iii) do not have the right to receive expected residual returns of the entity; or (c) the entity’s equity holders have voting rights that are not proportionate to their economic interests, and the activities of the entity involve or are conducted on behalf of the equity holder with disproportionately few voting rights. If an entity is deemed to be a VIE pursuant to ASC 810, an enterprise that has both: (i) the power to direct the activities of a VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb the expected losses of the entity or right to receive benefits from the entity that could be potentially significant to the VIE, is considered the primary beneficiary and must consolidate the VIE. In accordance with ASC 810, the Company performs ongoing reassessments of whether an enterprise is the primary beneficiary of a VIE. In the ordinary course of business, the Company enters into land option agreements in order to procure land for the construction of homes in the future. Pursuant to these land option agreements, the Company generally provides a deposit to the seller as consideration for the right to purchase land at different times in the future, usually at predetermined prices. Such contracts enable the Company to defer acquiring portions of properties owned by third parties or unconsolidated entities until the Company has determined whether and when to exercise its option, which reduces the Company’s financial risks associated with long-term land holdings. Option deposits and pre-acquisition costs (such as environmental testing, surveys, engineering, and entitlement costs) are capitalized if the costs are directly identifiable with the land under option and acquisition of the property is probable. Such costs are reflected in earnest money deposits and are reclassified to inventory upon taking title to the land. The Company writes off deposits and pre-acquisition costs when it becomes probable that the Company will not go forward with the project or recover the capitalized costs. Such decisions take into consideration changes in local market conditions, the timing of required land takedowns, the availability and best use of necessary incremental capital, and other factors. As of December 31, 2016 , the Company had land option agreements with potential purchase payments through 2019 . Under ASC 810, a non-refundable deposit paid to an entity is deemed to be a variable interest that will absorb some or all of the entity’s expected losses if they occur and, as such, the Company’s land option agreements are considered variable interests. The Company’s land options agreement deposits along with any related pre-acquisition costs represent the Company’s maximum exposure to the land seller if the Company elects not to purchase the optioned property. Therefore, whenever the Company enters into a land option or purchase contract with an entity and makes a non-refundable deposit, a VIE assessment is reviewed. However, the Company generally has little control or power to direct the activities that most significantly impact the VIE's economic performance due to the Company’s lack of an equity interest in them. Additionally, creditors of the VIE typically have no recourse against the Company, and the Company does not provide financial or other support to these VIEs other than as stipulated in the land option agreements. In accordance with ASC 810, the Company performs ongoing reassessments of whether the Company is the primary beneficiary of a VIE. As a result of the foregoing, the Company was not required to consolidate any VIE as of December 31, 2016 and 2015 . Sales with Option to Repurchase The Company sold land and then entered into land option contracts to repurchase the land from the buyers. Our utilization of land option contracts is dependent on, among other things, the availability of land sellers willing to enter into these arrangements, the availability of capital to finance the development of optioned lots, general housing market conditions, and local market dynamics. Options may be more difficult to procure from land sellers in strong housing markets and are more prevalent in certain geographic regions. For accounting purposes in accordance with ASC 360-20-40-38, Property, Plant, and Equipment , these transactions are considered a financing rather than a sale. As a result, the Company recorded $9.3 million and $16.2 million as of December 31, 2016 and 2015 , respectively, to land not owned under option agreements with a corresponding increase to obligations related to land not owned under option agreements on the consolidated balance sheets. Investment in Direct Financing Leases Through December 31, 2014, the Company entered into a series of direct finance leases for a portfolio of model homes. The Company leased these model homes to the entity that it acquired the homes from. The lessee had the option to repurchase the model homes at a predetermined price. The direct financing leases bore interest at rates from 10% to 12% . The lease payments were recorded as interest income on direct financing leases in the consolidated statements of income. All direct financing leases were sold in 2015. Property and Equipment, Net Property and equipment are stated at cost less accumulated depreciation. Repairs and maintenance are expensed as incurred. Depreciation is computed over the estimated useful lives of the assets using the straight line method. The estimated useful lives of assets range from three to ten years. Customer and Builder Deposits The Company typically requires customers to submit a deposit for home purchases and for builders to submit a deposit in connection with their construction loan agreements. The deposits serve as a guarantee to performance under home purchase and building contracts. Cash received as customer deposits, if held in escrow, are shown as restricted cash on the consolidated balance sheets. Warranties The Company accrues an estimate of its exposure to warranty claims based on both current and historical home sales data and warranty costs incurred. The Company offers homeowners a comprehensive third party warranty on each home. Homes are generally covered by a ten year warranty for qualified and defined structural defects, one year for defects and products used, and two years for electrical, mechanical and plumbing systems. The Company accrues between $1,200 and $2,000 per home closed for future warranty claims, and evaluates the adequacy of the reserve annually. Warranty accruals are included within accrued expenses on the consolidated balance sheets. Net Income Attributable to Green Brick Partners, Inc. per Share The Company's restricted stock awards have the right to receive forfeitable dividends on an equal basis with common stock and therefore are not considered participating securities that must be included in the calculation of net income per share using the two-class method. Basic earnings per share is computed by dividing net income by the weighted average number of common shares outstanding during each period, adjusted for non-vested shares of restricted stock awards during each period. Diluted earnings per share is calculated using the treasury stock method and includes the effect of all dilutive securities, including stock options and restricted stock awards. The computation of basic and diluted net income attributable to Green Brick Partners, Inc. per share using the treasury stock method is as follows (in thousands, except per share amounts): Years End December 31, 2016 2015 2014 Basic net income attributable to Green Brick Partners, Inc. per share Net income attributable to Green Brick Partners, Inc. —basic $ 23,756 $ 15,325 $ 50,026 Weighted-average number of shares outstanding —basic 48,879 40,068 14,712 Basic net income attributable to Green Brick Partners, Inc. per share $ 0.49 $ 0.38 $ 3.40 Diluted net income attributable to Green Brick Partners, Inc. per share Net income attributable to Green Brick Partners, Inc. —diluted $ 23,756 $ 15,325 $ 50,026 Weighted-average number of shares used to compute basic net income attributable to Green Brick Partners, Inc. 48,879 40,068 14,712 Dilutive effect of stock options and restricted stock awards 7 30 — Weighted-average number of shares outstanding —diluted 48,886 40,099 14,712 Diluted net income attributable to Green Brick Partners, Inc. per share $ 0.49 $ 0.38 $ 3.40 The following securities that could potentially dilute earnings per share in the future are not included in the determination of diluted net income attributable to Green Brick Partners, Inc. per common share (in thousands): Years End December 31, 2016 2015 2014 Antidilutive options to purchase common stock 144 62 129 Revenue Recognition Revenue from sales of residential units, land and lots are not recognized until a sale is deemed to be consummated. Consummation is defined as: a) when the parties are bound by the terms of a contract; b) all net consideration has been exchanged; c) any permanent financing for which the seller is responsible has been arranged; d) continuing investment is adequate to demonstrate a commitment to pay for the home; and e) all conditions precedent to closing have been performed. Generally, consummation does not happen until a sale has closed. When the earnings process is complete and a sale has closed, income is recognized under the full accrual method which allows full recognition of the gain on the sale at the time of closing. We also serve as the general contractor for certain custom homes where the customers, and not our company, own the underlying land and improvements. We recognize revenue for these mechanics liens contracts on the percentage of completion method, where progress toward completion is measured by relating the actual cost of work performed to date to the current estimated total cost of the respective contracts. During the years ended December 31, 2016 , 2015 and 2014 , we recognized revenue of $12.5 million , $7.7 million and $6.9 million , respectively, and incurred costs of $11.1 million , $5.9 million and $4.4 million , respectively, associated with mechanic liens contracts, which is presented net in other income, net on the consolidated statements of income. Cost Recognition Lot acquisition, materials, direct costs, interest and indirect costs related to the acquisition, development, and construction of lots and homes are capitalized. Direct and indirect costs of developing residential lots are allocated evenly to all applicable lots. Capitalized costs of residential lots are charged to earnings when the related revenue is recognized. Non-capitalizable costs in connection with developed lots and completed homes and other selling and administrative costs are charged to earnings when incurred. We recognize costs as incurred on our mechanics lien contracts. Advertising Expense The Company expenses advertising as incurred. Advertising costs are included in selling, general and administrative expense in the consolidated statements of income. Advertising expense for the years ended December 31, 2016 , 2015 and 2014 totaled $0.7 million , $0.5 million and $0.4 million , respectively. Debt Issuance Costs Debt issuance costs of $0.8 million and $0.8 million as of December 31, 2016 and December 31, 2015 , represent costs incurred related to the revolving and unsecured credit facilities, including amendments thereto, and are included as part of other assets, net on the consolidated balance sheets. These costs are amortized straight line through interest expense over the term of the related debt facility. Share-Based Compensation The Company measures and accounts for share-based awards in accordance with ASC Topic 718, “ Compensation - Stock Compensation ”. The Company expenses share-based payment awards made to employees and directors, including stock options and restricted stock awards. Share-based compensation expense associated with stock options and restricted stock awards with vesting contingent upon the achievement of service conditions is recognized on a straight-line basis, net of estimated forfeitures, over the requisite service period the awards are expected to vest. The Company estimates the value of stock options with vesting contingent upon the achievement of service conditions as of the date the award was granted using the Black-Scholes option pricing model. The Black-Scholes option-pricing model requires the use of certain input variables, such as expected volatility, risk-free interest rate and expected award life. Income Taxes Until October 27, 2014, JBGL (the accounting acquirer of Green Brick) was not a taxable entity for U.S. federal and state income tax purposes with the exception of Texas. Taxes on its net income were borne by its members through the allocation of taxable income. Upon completion of the reverse recapitalization of Green Brick, JBGL became part of a consolidated taxable entity. The Transaction resulted in the change of JBGL’s tax status that resulted in the recognition of a one-time income tax benefit in the consolidated statement of income of approximately $26.6 million in the year ended December 31, 2014. BioFuel had approximately $182.3 million of federal net operating loss carryforwards and approximately $21.6 million of state net operating loss carryforwards as of the Transaction Date. The Company re-assessed the need for a valuation allowance as of the Transaction Date and concluded, on a more-likely-than-not basis, that the deferred income tax assets, except for the state loss carryforwards, would be realized, giving consideration to the historical, current year and projected operating results of Green Brick. As a result of the re-assessment, the Company recorded $63.9 million of net deferred income tax assets at the Transaction Date, with an offset in additional paid-in-capital. The effect of the re-assessment had no impact on income tax expense. The Company accounts for income taxes using the asset and liability method, under which deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases, operating losses and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in years in which temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. The Company regularly reviews historical and anticipated future pre-tax results of operations to determine whether we will be able to realize the benefit of deferred tax assets. A valuation allowance is required to reduce the deferred tax asset when it is more-likely-than-not that all or some portion of the deferred tax asset will not be realized due to the lack of sufficient taxable income. The Company establishes reserves for uncertain tax positions that reflect its best estimate of deductions and credits that may not be sustained on a more-likely-than-not basis. The Company recognizes interest and penalties related to uncertain tax positions in income tax provision on the consolidated statements of income. Accrued interest and penalties are included in the related tax liability account within accrued expenses on the consolidated balance sheets. As of December 31, 2016 , we had deferred tax assets of $67.6 million , which was net of a valuation allowance in the amount of $1.1 million relating to state loss carryforwards. The deferred tax assets are primarily related to $40.8 million for federal net operating loss carryforwards and $22.9 million for basis in partnerships. For accounting purposes, a valuation allowance is required to reduce a deferred tax asset if it is determined that it is more-likely-than-not that all or some portion of the deferred tax asset will not be realized due to the lack of sufficient taxable income or other limitation on the Company’s ability to utilize the loss carryforward. Prior to the Transaction, BioFuel had recorded a valuation allowance against the full value of the deferred tax assets related to federal and state net operating losses due to a history of operating losses. The valuation allowance attributable to deferred tax assets other than the state loss carryforwards recorded by BioFuel prior to the Transaction Date was reversed through equity on the Transaction Date. The net operating loss carryforwards will begin to expire beginning with the year ending December 31, 2029 . The Company’s ability to utilize its net operating loss carryforwards will depend on the amount of taxable income that the Company generates in future periods. Based on our 2016 , 2015 , and 2014 taxable income results and forecast projections of taxable income, Company management expects that the Company should generate sufficient taxable income to utilize substantially all of the net operating loss carryforwards before they expire. The Company will continue to evaluate the appropriateness of a valuation allowance in future periods based on the consideration of all available evidence, including the generation of taxable income, using the more-likely-than-not standard. Fair Value Measurements The Company has adopted and implemented the provisions of FASB ASC 820-10, Fair Value Measurements , with respect to fair value measurements of: (a) all elected financial assets and liabilities; and (b) any nonfinancial assets and liabilities that are recognized or disclosed in the consolidated financial statements at fair value on a recurring basis (at least annually). Under FASB ASC 820-10, fair value is defined as an exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. These provisions establish a three-tiered fair value hierarchy that prioritizes inputs to valuation techniques used in fair value calculations. The three levels of input are defined as follows: Level 1 — unadjusted quoted prices for identical assets or liabilities in active markets accessible by the Company; Level 2 — inputs that are observable in the marketplace other than those classified as Level 1; and Level 3 — inputs that are unobservable in the marketplace and significant to the valuation. Entities are encouraged to maximize the use of observable inputs and minimize the use of unobservable inputs. If a financial instrument uses inputs that fall in different levels of the hierarchy, the instrument will be categorized based upon the lowest level of input that is significant to the fair value calculation. Our valuation methods may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while we believe our valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date. As of December 31, 2016 and 2015 there were no assets or liabilities carried at fair value. Noncontrolling Interests We own 50% controlling interests in several builders. The financial statements of these builders are consolidated in our consolidated financial statements. The noncontrolling interests attributable to the 50% minority interests not owned by us are included as part of noncontrolling interests on the consolidated balance sheets. Segment Information In accordance with ASC 280, Segment Reporting , an operating segment is defined as a component of an enterprise for which discrete financial information is available and is reviewed regularly by the Chief Operating Decision Maker (“CODM”), or decision-making group, to evaluate performance and make operating decisions. The Company identified its CODM as three key executives—the Chief Executive Officer, the Chief Financial Officer and the Head of Land Acquisition and Development. In determining the most appropriate reportable segments, the CODM considered similar economic and other characteristics, including geography, class of customers, product types and production processes. During the year ended December 31, 2015 , the Company organized its operations into two reportable segments: builder operations and land development. The builder operations segment includes the Company's controlled builders results, which include building and selling single-family detached homes and townhomes that are designed and built to meet local customer preferences, and the sale of lots. Builder operations consisted of two operating segments: Texas and Georgia. The land development segment includes operations related to the acquisition and development of land which is sold to the Company’s controlled builders and third-party homebuilders. During the fourth quarter of 2016 , the Company re-evaluated its reportable segments unde |
