Summary of Significant Accounting Policies | SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned, majority-owned and controlled subsidiaries, and have been prepared in accordance with the accounting principles generally accepted in the United States of America ("GAAP"). All intercompany accounts have been eliminated upon consolidation. As an “emerging growth company,” as defined in the Jumpstart Our Business Startups Act of 2012, the Company has taken advantage of certain temporary exemptions from various reporting requirements, including reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements. The Company could be an emerging growth company until the last day of the fiscal year following the fifth anniversary of the July 23, 2013 completion of its IPO, although a variety of circumstances could cause it to lose that status earlier. Use of Estimates in Preparation of Financial Statements: The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect the disclosure and reported amounts of assets and liabilities reported in the consolidated financial statements and accompanying notes. Significant estimates relate to the assessment of real estate impairments, valuation of assets and liabilities acquired, cost capitalization, accrued obligations, warranty reserves, income taxes and contingent liabilities. While management believes that the carrying value of such assets and liabilities are appropriate as of December 31, 2016 and 2015 , it is reasonably possible that actual results could differ from the estimates upon which the carrying values were based. Related Party Transactions: As of December 31, 2016 , PICO holds an economic and voting interest in our Company equal to approximately 56.8% . The Company is party to certain agreements with PICO, including an Exchange Agreement (pursuant to which PICO has the right to cause the Company to exchange PICO’s interests in UCP, LLC for shares of the Company’s Class A common stock on a one-for-one basis, subject to equitable adjustments for stock splits, stock dividends, reclassifications and repurchases by UCP of Class A common stock), an Investor Rights Agreement (pursuant to which PICO has certain rights, including the right to select two individuals for nomination for election to the Company’s board of directors for as long as PICO owns at least a 25% voting interest in the Company), a TRA (pursuant to which PICO is entitled to 85% of any cash savings in U.S. federal, state and local income tax that the Company actually realizes as a result of any increase in tax basis caused by PICO’s exchange of UCP, LLC interests for shares of the Company’s Class A common stock), a Registration Rights Agreement, with respect to the shares of Class A common stock that PICO may receive in exchanges made pursuant to the Exchange Agreement and a TSA (pursuant to which PICO provides certain administrative support services to UCP, Inc.). On July 31, 2015, the Company fully transitioned the services under the TSA, therefore, the balance due to PICO pursuant to the TSA and expense allocations of other amounts payable due to PICO was approximately zero for both years ended December 31, 2016 and 2015 . For the years ended December 31, 2015 and 2014 , the Company incurred $119,000 and $615,000 for services under the TSA. Segment Reporting: The Company has segmented its operating activities into two operating segments, West and Southeast, and two reportable segments, Homebuilding and Land development. In accordance with the applicable accounting guidance, the Company considered similar economic and other characteristics, including geography, product types, average selling prices, gross margins, production processes, suppliers, subcontractors, regulatory environments, land acquisition results and underlying supply and demand in determining its reportable segments. Each reportable segment includes real estate with similar economic characteristics, including similar historical and expected long-term gross margin percentages, product types, geography, production processes and methods of distribution. Cash and Cash Equivalents: Cash and cash equivalents include highly liquid instruments purchased with original maturities of three months or less. The Company has approximately $15.1 million of cash held in money market accounts on its consolidated balance sheets as of December 31, 2016 . Cash items that are restricted as to withdrawal or usage included deposits of $1.5 million and $0.9 million for the years ended December 31, 2016 and 2015 , respectively. For both periods, restricted cash items related to a construction loan, credit card agreements and a contractor's license. The year ended December 31, 2016 includes restricted cash related to a letter of credit. Capitalization of Interest: The Company capitalizes interest to real estate inventories during the period that real estate is undergoing development. Interest capitalized as a cost of real estate inventories is included in cost of sales-homebuilding or cost of sales-land development as related homes or real estate are delivered. To the extent the Company's debt exceeds the cost of the related qualifying asset under development, the Company expenses that portion of the interest incurred. Qualifying assets include projects that are actively under construction or under development. Advertising Expenses: The Company expenses advertising costs as incurred. Advertising expenses for the years ended December 31, 2016 and 2015 was $2.3 million for both periods and $2.0 million for the year ended December 31, 2014 . Real Estate Inventories and Cost of Sales: The Company capitalizes pre-acquisition costs, the purchase price of real estate, development costs and other allocated costs, including interest, during development and home construction. Pre-acquisition costs, including non-refundable land deposits, are expensed to cost of sales when the Company determines continuation of the related project is not probable. Applicable costs incurred after development or construction is substantially complete are charged to sales and marketing or general and administrative ("G&A") expenses, as appropriate. Land, development and other common costs are typically allocated to real estate inventories based on the number of homes to be constructed. Direct home construction costs are recorded using the specific identification method. Cost of sales-homebuilding includes the construction costs of each home and all applicable land acquisition, real estate development, capitalized interest and related allocated common costs. Changes to estimated total development costs subsequent to initial home closings in a community are allocated to remaining homes in the community. Cost of sales-land development includes land acquisition and development costs, capitalized interest, impairment charges, abandonment charges for projects that are no longer economically viable, and real estate taxes. Real estate inventories are stated at cost, unless the carrying amount is determined not to be recoverable, in which case real estate inventories are written down to fair value. All real estate inventories are classified as held until the Company commits to a plan to sell the real estate, the real estate can be sold in its present condition, the real estate is being actively marketed for sale and it is probable that the real estate will be sold within twelve months. Homes completed or under construction are included in real estate inventories in the accompanying consolidated balance sheets at the lower of cost or net realizable value. Impairment and Abandonment of Real Estate Inventories: The Company evaluates real estate inventories for impairment when conditions exist suggesting that the carrying amount of real estate inventories is not fully recoverable and may exceed its fair value. Indicators of impairment include, but are not limited to, significant decreases in local housing market values, decreases in the selling prices of comparable homes, significant decreases in gross margins and sales absorption rates, costs in excess of budget, and actual or projected cash flow losses. The Company prepares and analyzes cash flows at the lowest level for which there are identifiable cash flows that are independent of the cash flows of other groups of assets. When estimating future cash flows of its real estate assets, the Company makes various assumptions, including: (i) expected sales prices and sales incentives (based on, among other things, an estimate of the number of homes available in the market, pricing and incentives, and potential 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 incurred to date and expected to be incurred (including, but not limited to, land and land development costs, home construction costs, indirect construction 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. If events or circumstances indicate that the carrying amount of real estate inventories may be impaired, such impairment will be measured based upon the difference between the carrying amount and the fair value of such asset(s) determined using the estimated future discounted cash flows, excluding interest charges, generated from the use and ultimate disposition of such asset(s). Such losses, if any, are reported within cost of sales for the period. We estimate the fair value of each impaired community by determining the present value of the estimated future cash flows at a discount rate commensurate with the risk of the respective community. In determining the fair value of land held for sale, management considers, among other things, prices for land in recent comparable sale transactions, market analysis studies, which include the estimated price a willing buyer would pay for the land, and recent bona fide offers received from third parties. During the year ended December 31, 2016 , approximately $2.6 million of impairment losses were recorded. Approximately $2.4 million of impairment losses were recorded with respect to the Company’s real estate inventories at Sundance, located in Bakersfield, California ("Sundance"). The 65 lots remaining at the Sundance project were under contract for sale and resulted in an impairment loss of $2.1 million , as the carrying value of these lots was written down to the contractual sales price less costs to sell. In addition, homes under construction and completed homes at the Sundance project had a carrying value that exceeded their estimated undiscounted cash flows during the year ended December 31, 2016 . As a result, the carrying values of those remaining lots not currently under contract at Sundance were adjusted to their estimated fair values resulting in an impairment loss of approximately $0.3 million . Furthermore, approximately $0.2 million of impairment loss was recorded during the year ended December 31, 2016 with respect to the Company’s real estate inventories at Heathers at Westport, located in Charlotte, North Carolina ("Heathers at Westport"). The four remaining completed homes at the Heathers at Westport project had a carrying value that exceeded their estimated undiscounted cash flow. As a result, the carrying values of those remaining homes were adjusted to their estimated fair values. For the year ended December 31, 2015 , approximately $0.9 million of impairment loss was recorded t o homebuilding real estate inventory at the River Run project, located in Bakersfield, California ("River Run") to adjust its carrying value to its estimated fair value as of the date of the impairment. For the year ended December 31, 2014 , no such real estate impairment loss was recorded. See Note 9 , “Fair Value Disclosures--Non-Financial Instruments Carried at Fair Value--Non-Recurring Estimated Fair Value of Real Estate Inventories” to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further discussion of the impairment of the real estate assets. Abandonment charges during the years ended December 31, 2016 , 2015 and 2014 , were $523,000 , $152,000 , and $173,000 , respectively. Abandonment charges are included in cost of sales in the accompanying consolidated statements of operations and comprehensive income or loss for the period in which they were recorded. These charges were related to the Company electing not to proceed with one or more land acquisitions after the incurrence of costs during due diligence. Goodwill and Other Intangible Assets: The purchase price of an acquired business is allocated between the net tangible assets and intangible assets of the acquired business with any residual purchase price recorded as goodwill. The determination of the value of the assets acquired and liabilities assumed involves certain judgments and estimates. These judgments can include, but are not limited to, the cash flows that an asset is expected to generate in the future and the appropriate weighted average cost of capital. Intangible assets with determinable useful lives are amortized on a straight-line basis over the estimated remaining useful lives (ranging from six months to five years), added to the value of land when an intangible option is used to purchase the related land, or expensed in the period when the option is cancelled. Acquired intangible assets with contractual terms are generally amortized over their respective contractual lives. When certain events or changes in operating conditions occur, an impairment assessment is performed for the intangible assets. Goodwill is not amortized, but is evaluated annually for impairment or more frequently if events or circumstances indicate that goodwill may be impaired. Impairment of Goodwill: All goodwill has been attributed to the Southeast homebuilding reporting segment as part of the Citizens Acquisition, which was completed in 2014. In accordance with Financial Accounting Standards Board (“FASB”) issued Accounting Standards Codification (“ASC”) Topic 350 - Goodwill, the Company evaluates goodwill for impairment annually or when conditions exist suggesting that the carrying amount of goodwill will more likely than not exceed its fair value. Indicators of impairment include, but are not limited to, significant decreases in economic conditions and market valuations, limitations on access to capital, and actual or projected cash flow losses or increases in cost factors that have a negative effect on earnings and cash flows. The Company prepares and analyzes cash flows at the project level for which there are identifiable cash flows. If events or circumstances indicate that the carrying amount of goodwill may be impaired, such impairment will be measured based upon the difference between the carrying amount and the fair value and determined using the estimated future discounted cash flows, excluding interest charges. Such losses, if any, are reported as an expense in the accompanying consolidated statements of operations and comprehensive income or loss for the period. We estimate the fair value of goodwill by applying the income approach and determining the present value of the estimated future cash flows at a discount rate. When estimating future cash flows, the Company makes various assumptions, including, but not limited to: (i) forecasted adjusted pre-tax net income over a ten -year period; (ii) weighted average cost of capital; (iii) terminal growth; and (iv) revenue growth and operating profit margin. Based on the above factors, the Company determined that the carrying value of goodwill exceeded its fair value. As a result, the Company recorded goodwill impairment of $4.2 million during the year ended December 31, 2016 related to its Southeast operating segment. For the years ended December 31, 2015 and 2014 , there was no impairment of goodwill. See Note 6 , “Intangible Assets--Goodwill” to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further discussion of the impairment of goodwill. Fixed Assets, Net: Fixed assets are carried at cost, net of accumulated depreciation. Depreciation is computed using the straight-line method over the estimated remaining useful lives of the assets. Computer software and hardware are depreciated over three to five years, office furniture and fixtures are depreciated over five years, vehicles are depreciated over five years and leasehold improvements are depreciated over the shorter of their useful life or lease term and range from one to five years. Maintenance and repairs are charged to expense as incurred, while significant improvements are capitalized. Depreciation expense is included in G&A expenses in the accompanying consolidated statements of operations and comprehensive income or loss. Receivables: The detail of receivables is set forth below (in thousands): December 31, 2016 December 31, 2015 Warranty insurance receivables $ 1,118 $ — Manufacturer rebates 454 425 Reimbursement for land development work 4,016 — Other receivables 40 892 Total $ 5,628 $ 1,317 Receivables include amounts recoverable from warranty insurance, amounts due from utility companies for reimbursement of costs, manufacturer rebates and reimbursable land development costs under a fixed price contract. As of December 31, 2016 , approximately $1.1 million of estimated recoverable from warranty insurance was included in receivables. In addition, approximately $4.0 million of reimbursable land development costs under an option and development agreement executed during the year ended December 31, 2016 was recorded as a receivable. As of December 31, 2016 , and 2015 , the Company had no allowance for doubtful accounts recorded. Other Assets: The detail of other assets is set forth below (in thousands): December 31, 2016 December 31, 2015 Customer deposits in escrow $ 2,394 $ 1,834 Prepaid expenses 1,098 2,099 Other deposits and prepaid interest 1,345 466 Funds held in escrow 1,490 1,490 Total $ 6,327 $ 5,889 As part of the Company’s adoption of Accounting Standards Update (“ASU”) 2015-03, approximately $1.5 million of unamortized debt issuance costs that were included in the prepaid expenses category of other assets as of December 31, 2015 have been reclassified from other assets to notes payable and senior notes in the accompanying consolidated balance sheets. See Note 8 , “Notes Payable and Senior Notes, net” to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for a further discussion of the change in accounting principle. Homebuilding, Land Development Sales and Other Revenues Profit Recognition: In accordance with applicable guidance under ASC Topic 360 - Property, Plant, and Equipment , revenue from home sales and other real estate sales is recorded and any profit is recognized when the respective sales are closed. Sales are closed when all conditions of escrow are met, title passes to the buyer, appropriate consideration is received and collection of associated receivables, if any, is reasonably assured and the Company has no continuing involvement with the sold asset. The Company does not offer financing to any buyers. Sales price incentives are accounted for as a reduction of revenues when the sale is recorded. If the earnings process is not complete, the sale and any related profits are deferred for recognition in future periods. Any profit recorded is based on the calculation of cost of sales, which is dependent on an allocation of costs. In addition to homebuilding and land development, the Company previously provided construction management services, pursuant to which it built homes on behalf of third-party property owners. The Company entered into “cost plus fee” contracts where property owners were charged for all direct and indirect costs plus a negotiated management fee. In accordance with ASC Topic 605 - Revenue Recognition , revenues from construction management services are recognized based upon a cost-to-cost approach in applying the percentage-of-completion method. Under this approach, revenue is earned in proportion to total costs incurred, divided by total costs expected to be incurred. The total estimated cost plus the management fee represents the total contract value. The Company recognized revenue based on the actual costs incurred, plus the portion of the management fee it has earned to date. In the course of providing construction management services, the Company routinely subcontracts for services and incurs other direct costs on behalf of the property owners. The business was acquired in connection with the Citizens Acquisition in 2014 and was sold during 2015. We no longer provide construction management services to third parties. Revenue and costs from providing these services for the year ended December 31, 2015 is included in other revenue and cost of sales-other revenue in the accompanying consolidated statements of operations and comprehensive income or loss. Stock-Based Compensation: Stock-based compensation expense is measured at the grant date based on the fair value of the award and is recognized as expense over the period during which the awards vest in accordance with applicable guidance under ASC 718 - Compensation - Stock Compensation. See Note 10 , "Equity--Stock-Based Compensation" to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further discussion on stock-based compensation. Stock Repurchase Program: Our Board of Directors authorized the Stock Repurchase Program on June 6, 2016 to repurchase up to $5.0 million of the Company’s Class A common stock between June 7, 2016 and June 1, 2018. Treasury stock represents shares repurchased under the Stock Repurchase Program, which are reflected as a reduction in Stockholders’ Equity in accordance with ASC Topic 505-30 - Equity - Treasury Stock . The number of shares repurchased is based on the settlement date and factored into our weighted average calculation for earnings per share ("EPS"). See Note 10 , “Equity--Stock Repurchase Program” to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for additional information regarding the Stock Repurchase Program. Warranty Reserves: Estimated future direct warranty costs are accrued and charged to cost of sales-homebuilding in the period in which the related homebuilding revenue is recognized. Amounts accrued are based upon estimates of the amount the Company expects to pay for warranty work. The Company assesses the adequacy of its warranty reserves on a quarterly basis and adjusts the amounts recorded, if necessary, in the period in which the change in estimate occurs. Annually, or more frequently as needed, the Company engages a third-party actuary to assist in the analysis of warranty reserves based on historical data and industry trends for our communities. Warranty reserves are included in accrued liabilities in the accompanying consolidated balance sheets. Changes in warranty reserves are detailed in the table set forth below (in thousands): December 31, 2016 December 31, 2015 Warranty reserves, beginning of period $ 2,852 $ 1,509 Warranty reserves accrued 2,377 1,507 Warranty expenditures (705 ) (164 ) Additional reserves where corresponding amounts are recorded as receivables from insurance carriers 1,118 — Warranty reserves, end of period $ 5,642 $ 2,852 Consolidation of Variable Interest Entities: The Company enters into purchase and option agreements for the purchase of real estate as part of the normal course of business. These purchase and option agreements enable the Company to acquire real estate at one or more future dates at pre-determined prices. The Company believes these acquisition structures reduce its financial risk associated with real estate acquisitions and holdings and allow the Company to better manage its cash position and return metrics. In February 2015, the FASB issued ASU No. 2015-02, Consolidation (Topic 810): Amendments to the Consolidation Analysis (“ASU 2015-02”), to simplify consolidation accounting. The Company adopted the provisions of ASU 2015-02 as of January 1, 2016. In accordance with ASC Topic 810, " Consolidation ," the Company assesses each purchase agreement to acquire real estate from an entity to determine if a variable interest entity ("VIE") may be created. Although the Company may not have legal title to the underlying land, if the Company determines that it is the primary beneficiary of the VIE, the Company would consolidate the VIE in its accompanying consolidated financial statements and reflect such assets and liabilities as “Real estate inventories not owned.” In determining if the Company is the primary beneficiary, the Company considers, among other things, whether it has the ability to control the activities of the VIE that most significantly impact its economic performance. Such activities include, but are not limited to: the ability to determine the budget or scope of the VIE; the ability to control financing decisions for the VIE; and the ability to acquire or dispose of property owned or controlled by the VIE. Based on the current provisions of the relevant accounting guidance, the Company evaluated its purchase and option agreements for real estate in place as of December 31, 2016 or 2015 . None met consolidation criteria under ASU 2015-02. Income Taxes: The Company’s provision for income tax expense includes federal and state income taxes currently payable and those deferred because of temporary differences between the income tax and financial reporting basis of the Company's assets and liabilities. The asset and liability method of accounting for income taxes also requires the Company to reflect the effect of a tax rate change on accumulated deferred income taxes in income in the period in which the change is enacted. In assessing the realization of deferred income taxes, the Company considered whether it is more likely than not that any deferred income tax assets will be realized. The realization of deferred income tax assets is subject to the Company generating of sufficient taxable income during the periods in which the deferred tax assets become realizable. If it is more likely than not that some or all of the deferred income tax assets will not be realized, a valuation allowance is recorded. The Company considered many factors when assessing the likelihood of future realization of its deferred tax assets, including recent cumulative earnings experience by taxing jurisdiction, expectations of future transactions, the carry-forward periods available to the Company for tax reporting purposes and availability of tax planning strategies. These assumptions require significant judgment about future events. These judgments are consistent with the plans and estimates that the Company uses to manage the underlying businesses. In evaluating the objective evidence that historical results provide, the Company considered three years of cumulative operating income or loss of the Company and its predecessor. During the year ended December 31, 2016 , the Company evaluated all available evidence in determining the likelihood that it will be able to realize all or some portion of its deferred tax assets prior to their expiration. Upon completing this evaluation, the Company concluded that it is more likely than not that the Company will be able to realize its deferred tax assets. Due to the Company's cumulative profitability during the years ended 2016 , 2015 and 2014 , a valuation allowance reversal against the Company’s deferred tax assets was approximately $5.5 million . As a result of the reversal of the valuation allowance, the Company realized a one-time, non-cash tax benefit in the period of reversal. Prospectively, the Company would then expect to report an effective U.S. income tax rate that is closer to its statutory rates, other than as a result of the impact from the timing differences inherent to UCP, Inc.'s investment in UCP, LLC. See Note 14 , “Income Taxes” and Note 15 , "Deferred Tax Asset Valuation Allowance" to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for a further discussion of the Company’s income taxes and the valuation allowance reversal for the applicable period. As a result of the analysis of all available evidence as of December 31, 2015 and 2014 the Company's net deferred tax assets were subject to a full valuation allowance. The Company recognizes any uncertain income tax positions on income tax returns at the largest amount that is more-likely-than-not to be sustained upon audit by the relevant taxing authority. An uncertain income tax position will not be recognized unless it has a greater than 50% likelihood of being sustained. The Company recognizes any interest and penalties related to uncertain tax positions in income tax expense. For each of the periods presented, the Company did not record any interest or penalties related to uncertain tax positions. Price Participation Interests: Certain land purchase contracts and other agreements include provisions for additional payments to the land sellers. These additional payments are contingent on certain future outcomes, such as selling homes above a certain preset price or achieving an internal rate of return above a certain preset level. These additional payments, if triggered, are accounted for as cost of sales when they become due, however, they are neither fully determinable, nor due, until the transfer of title to the buyer is complete. Accordingly, no liability is recorded until the sale is complete. Noncontrolling Interest: The Company reports the share of the results of operations that are attributable to other owners of its consolidated subsidiaries that are less than wholly-owned as noncontrolling interest in the accompanying consolidated financial statements. In the accompanying consolidated statements of operations and comprehensive income or loss, the income or loss attributable to the noncontrolling interest is reported separately, and the accumulated income or loss attributable to the noncontrolling interest, along with any changes in ownership of the subsidiary, is reported as a component of total equity. For the years ended December 31, 2016 and 2015 , the noncontrolling interest reported in the accompanying consolidated financial statements includes PICO's share of 56.8% and 56.9% , respectively, of the income related to UCP, LLC. See Note 10 , "Equity--Noncontrolling Interest" to the consolidated financial statements included elsewhere in this Annual Report on Form 10-K for further discussion on noncontrolling interest. Recently Issued Accounting Standards: Standard Description Effective Date for the Company Application Effect on the Consolidated Financial Statements Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (ASU 2017-04) Simplifies the subsequent measurement of goodwill by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Instead, an entity should perform its goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount, considering income tax effects, and recognize an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized should not exceed the total amount of goodwill allocated to that reporting unit. January 1, 2020; early adoption permitted Prospective The Company currently has no goodwill recorded on its financial statements and will evaluate the method of adoption upon a future business combination when goodwill may be recorded. The Company does not expect to early adopt. Business Combinations (Topic 805): Clarifying the Definition of a Business (ASU 2017-01) Clarifies the definition of a business and the evaluation for determining whether transactions are accounted for as acquisitions (or disposals) of assets or businesses. The amendments provide a framework to assist entities in evaluating whether both an input and a substantive process are prese |
