Description of Business and Summary of Significant Accounting Policies | 1. Description of Business and Summary of Significant Accounting Policies Description of Business InfraREIT, Inc. is a Maryland corporation and the surviving corporation of a merger (Merger) with InfraREIT, L.L.C., a Delaware limited liability company, completed on February 4, 2015 in connection with the initial public offering (IPO) of InfraREIT, Inc. and related transactions effected during the first quarter of 2015 (collectively, the Reorganization). As used in these financial statements, unless the context requires otherwise or except as otherwise noted, the words “Company” and “InfraREIT” refer to InfraREIT, L.L.C., before giving effect to the Merger, and InfraREIT, Inc., after giving effect to the Merger, as the context requires, and also refer to the registrant’s subsidiaries, including InfraREIT Partners, LP (Operating Partnership or InfraREIT LP), a Delaware limited partnership, of which InfraREIT, Inc. is the general partner. The Merger was accounted for as a reverse acquisition, which means for accounting purposes the Company treated the assets and liabilities of InfraREIT, Inc. as assumed and incorporated with the assets and liabilities of InfraREIT, L.L.C. InfraREIT, Inc.’s operating results before the Merger primarily reflected costs related to obtaining a private letter ruling from the Internal Revenue Service and accounting services. The main assets and liabilities assumed were marketable securities of $1.1 million and a note payable of $1.0 million. The marketable securities were sold during February 2015 for $1.1 million resulting in a realized gain of $0.1 million which was recorded in other income (expense), net in the Consolidated Statements of Operations. Additionally, the note payable and associated interest were paid in full in February 2015. As a result, these financial statements present the 2015 operating results of InfraREIT, L.L.C. through the effectiveness of the Merger along with the operations of InfraREIT, Inc. thereafter. The Company has elected to be taxed as a real estate investment trust (REIT) for federal income tax purposes. The Company is externally managed and advised by Hunt Utility Services, LLC (Hunt Manager), a Delaware limited liability company. Hunt Manager is responsible for managing the Company’s day-to-day affairs, subject to the oversight of the Company’s board of directors. All of the Company’s officers, including the Company’s President and Chief Executive Officer, David A. Campbell, are employees of Hunt Manager. Mr. Campbell also serves as President and Chief Executive Officer of Sharyland Utilities, L.P. (Sharyland), a Texas-based utility and the Company’s sole tenant. The Company holds 72.2% of the outstanding partnership units (OP Units) in the Operating Partnership as of December 31, 2017. The Company includes the accounts of the Operating Partnership and its subsidiaries in the consolidated financial statements. Hunt Consolidated, Inc. (HCI) affiliates, current or former employees and members of the Company’s board of directors hold the other 27.8% of the outstanding OP Units as of December 31, 2017. Sharyland Distribution & Transmission Services, L.L.C. (SDTS) is the owner of rate-regulated assets located in the Texas. On November 9, 2017, SDTS exchanged its retail distribution assets and certain transmission assets for a group of transmission assets owned by Oncor Electric Delivery Company LLC (Oncor), as more fully described below in Note 2, Asset Exchange Transaction. SDTS leases all its regulated assets under several lease agreements to Sharyland, which operates and maintains the regulated assets. SDTS and Sharyland are each subject to regulation as an electric utility by the Public Utility Commission of Texas (PUCT). SDTS is authorized to own and lease its assets to Sharyland under a certificate of convenience and necessity (CCN) granted by the PUCT. Initial Public Offering and Reorganization InfraREIT, Inc. completed its IPO on February 4, 2015, issuing 23,000,000 shares of common stock at a price of $23.00 per share, resulting in gross proceeds of $529.0 million. Immediately after the closing of the IPO, InfraREIT, Inc. completed the Merger, with InfraREIT, L.L.C. merging with and into InfraREIT, Inc., and InfraREIT, Inc. as the surviving entity and general partner of the Operating Partnership. InfraREIT, Inc. used $172.4 million of the net proceeds from the IPO to fund the cash portion of the consideration issued in the Merger, as described in greater detail below. InfraREIT, Inc. contributed the remaining $323.2 million to the Operating Partnership in exchange for common OP Units (Common OP Units). The Operating Partnership used the net proceeds from the IPO that it received from InfraREIT, Inc.: • to repay an aggregate of $1.0 million of indebtedness to HCI; • to repay an aggregate of $72.0 million of indebtedness outstanding under the Operating Partnership’s revolving credit facility and $150.0 million of indebtedness outstanding under SDTS’s revolving credit facility; • to pay offering expenses (other than the underwriting discounts and commissions and the underwriter structuring fee) of $6.3 million; and • for general corporate purposes. The following bullets describe the Merger and related Reorganization that were effected in the first quarter of 2015. • On January 29, 2015, the Operating Partnership effected a reverse unit split whereby each holder of OP Units received 0.938550 OP Units of the same class in exchange for each such unit it held immediately prior to such time, which is referred to as the reverse unit split. Also, on January 29, 2015, InfraREIT, L.L.C. effected a reverse share split whereby each holder of shares received 0.938550 shares of the same class in exchange for each such share it held immediately prior to such time, which is referred to as the reverse share split. All references to unit, share, per unit and per share amounts in these consolidated financial statements and related disclosures have been adjusted to reflect the reverse share split and reverse unit split for all periods presented. • On January 29, 2015, InfraREIT, Inc. issued 1,700,000 shares of common stock to Hunt-InfraREIT, L.L.C. (Hunt-InfraREIT) as a non-cash reorganization advisory fee in accordance with a structuring fee agreement, resulting in the recognition of a $44.9 million non-cash expense in the first quarter of 2015. • On February 4, 2015, the Operating Partnership issued 1,700,000 OP Units to InfraREIT, Inc. in connection with the structuring fee issuance of 1,700,000 shares of InfraREIT, Inc. common stock described immediately above. • On February 4, 2015, the Operating Partnership issued an aggregate of 28,000 of its profit interest OP Units (LTIP Units) to members of InfraREIT’s board of directors. • On February 4, 2015, the Operating Partnership issued 983,418 Common OP Units to Hunt-InfraREIT in settlement of the Operating Partnership’s obligation to issue OP Units to Hunt-InfraREIT related to the competitive renewable energy zone (CREZ) project. • On February 4, 2015, the Operating Partnership issued Hunt-InfraREIT 1,167,287 Common OP Units as an accelerated payment of a portion of the carried interest agreed to in 2010 in connection with the organization of InfraREIT, L.L.C. To effect the shift in ownership from the pre-IPO investors to Hunt-InfraREIT, an equal number of OP Units held by InfraREIT, L.L.C. in the Operating Partnership were canceled at the same time. • On February 4, 2015, as a result of the Merger, (1) holders of 8,000,000 common shares of InfraREIT, L.L.C. received $21.551 per common share, which was equal to the IPO price less the underwriting discounts and commissions and an underwriting structuring fee, (2) holders of the remaining 19,617,755 common shares of InfraREIT, L.L.C. received 19,617,755 shares of InfraREIT, Inc. Class A common stock and (3) holders of 25,145 Class C shares of InfraREIT, L.L.C. received 25,145 shares of InfraREIT, Inc. Class C common stock. • On February 4, 2015, InfraREIT, Inc. contributed $323.2 million to the Operating Partnership in exchange for 15,000,000 Common OP Units. • On February 4, 2015, InfraREIT, Inc. issued 1,551,878 shares of common stock to Hunt-InfraREIT in exchange for 1,551,878 OP Units tendered for redemption by Hunt-InfraREIT in accordance with a redemption agreement. • On February 4, 2015, concurrently with the Merger, InfraREIT, Inc. purchased 6,242,999 common shares in consideration for the issuance of a promissory note to Westwood Trust, as trustee of a trust for the benefit of a charitable beneficiary, in the principal amount of $66.5 million. • Westwood Trust immediately transferred the promissory note to MC Transmission Holdings, Inc. (MC Transmission), and, immediately following receipt of the promissory note, MC Transmission purchased 3,325,874 Common OP Units from the Operating Partnership in consideration for the assignment of the promissory note. The promissory note was then transferred to InfraREIT, Inc. in exchange for the redemption of 6,242,999 OP Units held by InfraREIT, Inc. and the subsequent cancellation of such promissory note, resulting in no cash consideration being paid or received pursuant to the purchase from Westwood Trust or the sale of Common OP Units to MC Transmission. • On March 9, 2015, the Operating Partnership issued 2,329,283 Common OP Units to Hunt-InfraREIT, and InfraREIT, Inc. canceled an equal number of shares of Class A common stock and Class C common stock. Each remaining share of Class A common stock and Class C common stock then converted to common stock on a one-for-one basis. This issuance settled InfraREIT, L.L.C.’s pre-IPO investors’ carried interest obligation agreed to with Hunt-InfraREIT under the investment documents entered into by the parties in 2010. • On March 9, 2015, the 11,264 long-term incentive plan units issued to two of InfraREIT, L.L.C.’s non-voting directors in May 2014 converted on a one-to-one basis to Common OP Units. Limited Partnership Agreement In connection with the Reorganization, the Company adopted a Second Amended and Restated Limited Partnership Agreement which became effective with the closing of the IPO. Upon completion of the IPO, the Operating Partnership had five types of OP Units outstanding: Common OP Units, Class A OP Units, Class B OP Units, Class C OP Units and LTIP Units. On March 9, 2015, the Operating Partnership issued Common OP Units in exchange for outstanding Class A OP Units and Class C OP Units. Such Common OP Units were allocated among the holders of Class A OP Units and Class C OP Units, and the Class A OP Units, Class B OP Units and Class C OP Units were canceled. Following such allocation, the Company adopted a Third Amended and Restated Limited Partnership Agreement that eliminated the provisions related to the Reorganization and the description of the Class A OP Units, Class B OP Units and Class C OP Units; however, it continues to allow amendments to authorize and issue additional classes of OP Units in the future. Principles of Consolidation and Presentation The consolidated financial statements include the Company’s accounts and the accounts of all other entities in which the Company has a controlling financial interest with noncontrolling interest of consolidated subsidiaries reported separately. All significant intercompany balances and transactions have been eliminated. SDTS maintains accounting records in accordance with the uniform system of accounts, as prescribed by the Federal Energy Regulatory Commission (FERC). In accordance with the applicable consolidation guidance, the Company’s consolidated financial statements reflect the effects of the different rate making principles mandated by the FERC and the PUCT which regulate its subsidiaries’ operations. The accompanying historical consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (U.S. GAAP). In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. The historical financial information is not necessarily indicative of the Company’s future results of operations, financial position and cash flows. Use of Estimates The preparation of the Company’s consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. Regulation As the owner of rate-regulated assets, regulatory principles applicable to the utility industry also apply to SDTS. The financial statements reflect regulatory assets and liabilities under cost based rate regulation in accordance with accounting standards related to the effect of certain types of regulation. Regulatory decisions can have an impact on the recovery of costs, the rate earned on invested capital and the timing and amount of assets to be recovered by rates. See Note 6, Other Assets SDTS capitalizes allowance for funds used during construction (AFUDC) during the construction of its regulated assets, and SDTS’s lease agreements with Sharyland rely on FERC definitions and accepted standards regarding capitalization of expense to define key terms in the lease such as footprint projects, which are the expenditures SDTS is obligated to fund pursuant to the leases. The amounts funded for these footprint projects include allocations of Sharyland employees’ time and overhead allocations consistent with FERC policies and U.S. GAAP. The leases define “footprint projects” to be transmission or, if applicable, distribution projects that (1) are primarily situated within the Company’s current or previous distribution service territory, as applicable; (2) physically hang from the Company’s existing transmission assets, such as the addition of another circuit to the Company’s existing transmission lines or that are physically located within one of its substations or (3) connect or are otherwise added to transmission lines or other properties that comprise a part of the transmission assets acquired from Oncor. Sharyland cannot be removed as lessee without prior approval from the PUCT. SDTS transacts with Sharyland through several lease arrangements covering all the regulated assets. These lease agreements include provisions for additions and retirements of the regulated assets in the form of new construction or other capitalized projects. Cash and Cash Equivalents The Company considers all short-term, highly liquid investments with original maturities of three months or less to be cash equivalents. The Company’s account balances at one or more institutions periodically exceed the Federal Deposit Insurance Corporation (FDIC) insurance coverage and, as a result, there could be a concentration of credit risk related to amounts on deposit in excess of FDIC insurance coverage. The Company has not experienced any losses and believes the risk is not significant. Restricted Cash Restricted cash represents the principal and interest payable for two consecutive periods associated with the $25.0 million senior secured notes described in Note 8, Long-Term Debt Concentration of Credit Risk Sharyland is the Company’s sole tenant and all the Company’s revenue is driven by the leases with Sharyland. Inventory Inventory consists primarily of transmission and distribution parts and materials used in the construction of electric plant. Inventory is valued at average cost when it is acquired and used. Assets Held for Sale The Company records assets held for sale when certain criteria have been met as specified by Accounting Standard Codification (ASC) Topic 360, Property, Plant and Equipment Electric Plant, net Electric plant equipment is stated at the original cost of acquisition or construction, which includes the cost of contracted services, direct labor, materials, acquisition adjustments and overhead items. In accordance with the FERC uniform system of accounts guidance, SDTS recognizes, as a cost to construction work in progress (CWIP), AFUDC on other funds classified as other income (expense), net and AFUDC on borrowed funds classified as a reduction of the interest expense, net on the Consolidated Statements of Operations. The AFUDC blended rate utilized was 4.0%, 6.7% and 6.6% for the years ended December 31, 2017, 2016 and 2015, respectively. Depreciation of property, plant and equipment is calculated on a straight-line basis over the estimated service lives of the properties based on depreciation rates approved by the PUCT. Depreciation rates include plant removal costs as a component of depreciation expense, consistent with regulatory treatment. Actual removal costs incurred are charged to accumulated depreciation. When accrued removal costs exceed incurred removal costs, the difference is reclassified as a regulatory liability to retire assets in the future. The regulatory liability will be relieved as cost of removal charges are incurred upon asset retirement. Repairs are the responsibility of Sharyland as the lessee under the lease agreements. Betterments and improvements generally are the responsibility of SDTS and are capitalized. Provision for depreciation of electric plant is computed using composite straight-line rates as follows for each of the years ended December 31, 2017, 2016 and 2015: Rates Transmission plant 1.69% - Distribution plant 1.74% - 5.96% General plant 0.80% - 5.12% Impairment of Long-Lived Assets The Company evaluates impairment of its long-lived assets annually or whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. An impairment loss is recognized only if the carrying amount of a long-lived asset is not recoverable through expected future cash flows. Regulatory assets are charged to expense in the period in which they are no longer probable of future recovery. Goodwill Goodwill represents the excess of costs of an acquired business over the fair value of the assets acquired, less liabilities assumed. Goodwill is not amortized and is tested for impairment annually or more frequently if events or changes in circumstances arise. Accounting Standard Update (ASU) 2011-08, Testing of Goodwill for Impairment The Company’s annual goodwill impairment analysis, which was performed qualitatively during the fourth quarter of 2017, did not result in an impairment charge. As of December 31, 2017 and 2016, $138.4 million was recorded as goodwill on the Consolidated Balance Sheets. Investments An investment is considered impaired if the fair value of the investment is less than its cost. Generally, an impairment is considered other-than-temporary unless (1) the Company has the ability and intent to hold an investment for a reasonable period of time sufficient for an anticipated recovery of fair value up to (or beyond) the cost of the investment; and (2) evidence indicating that the cost of the investment is recoverable within a reasonable period of time outweighs evidence to the contrary. If impairment is determined to be other than temporary, then an impairment loss is recognized equal to the difference between the investment’s cost and its fair value. Deferred Financing Costs Amortization of deferred financing costs associated with the issuance of the $25.0 million senior secured notes and the revolving credit facilities is computed using the straight-line method over the life of the loan which approximates the effective interest method. Amortization of deferred financing costs associated with SDTS is computed using the straight-line method over the life of the loan in accordance with applicable regulatory guidance. Derivative Instruments The Company may use derivatives from time to time to hedge against changes in cash flows related to interest rate risk (cash flow hedging instrument). ASC Topic 815, Derivatives and Hedging Unrealized gains and losses on the effective cash flow hedging instrument are recorded as components of accumulated other comprehensive income. Realized gains and losses on the cash flow hedging instrument are recorded as adjustments to interest expense. Settlements of derivatives are included within operating activities on the Consolidated Statements of Cash Flows. Any ineffectiveness in the cash flow hedging instrument is recorded as an adjustment to interest expense in the current period. Income Taxes InfraREIT, L.L.C. elected to be treated as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended, commencing with its taxable year ended December 31, 2010, and InfraREIT, Inc. elected to be treated as a REIT commencing with its taxable year ended December 31, 2015. As a result, the Company generally will not be subject to federal income tax on its taxable income that is distributed to its stockholders. A REIT is subject to a number of other organizational and operational requirements, including a requirement that it currently distribute at least 90% of its annual taxable income (with certain adjustments). As a REIT, the Company expects to distribute at least 100% of its taxable income. Accordingly, there is no provision for federal income taxes in the accompanying consolidated financial statements. Even if the Company maintains its qualification for taxation as a REIT, it may be subject to certain state and local taxes on its income and property, including excise taxes, and federal corporate income taxes on any undistributed income. At December 31, 2016, the Company had net operating loss carryforwards for federal income tax purposes of $95.1 million. No net operating losses were used for the year ended December 31, 2017. The estimated net operating loss carryforward for federal tax purposes was $96.2 million at December 31, 2017 and will begin expiring in 2026. However, the Tax Cuts and Jobs Act (TCJA) repealed the corporate alternative minimum tax (AMT) for tax years beginning after December 31, 2017 thereby nullifying the Company’s AMT net operating loss carryover. The Company recognizes the impact of tax return positions that are more-likely-than-not to be sustained upon audit. Significant judgment is required to evaluate uncertain tax positions. The evaluation of uncertain tax positions is based upon a number of factors, including changes in facts or circumstances, changes in tax law, correspondence with tax authorities during the course of audits and effective settlement of audit issues. A reconciliation of the beginning and ending amount of unrecognized tax benefits follows: Years Ended December 31, (In thousands) 2017 2016 Balance at January 1 $ 3,827 $ 2,924 Additions based on tax positions related to the current year 1,037 903 Balance at December 31 $ 4,864 $ 3,827 The balance of unrecognized tax benefits relates to state taxes, all of which would impact the effective tax rate if recognized. It is reasonably possible that the amount of the Company’s unrecognized tax benefits will decrease in the next twelve months either because the Company’s position is approved through a ruling by the taxing jurisdiction or the Company agrees to a settlement. At this time, an estimate of the range of the reasonably possible change cannot be made. The Company recognizes interest and penalties related to unrecognized tax benefits as income tax expense in the Consolidated Statements of Operations. During each of the years ended December 31, 2017, 2016 and 2015, the Company recognized interest and penalties of $0.2 million. The Company had accrued interest and penalties of $0.8 million and $0.6 million at December 31, 2017 and 2016, respectively. With few exceptions, the Company is no longer subject to U.S. federal, state and local income tax examinations by tax authorities for years prior to 2013. On December 22, 2017, the TCJA was signed into law reducing the corporate federal income tax rate from 35% to 21%, effective for taxable years beginning on or after January 1, 2018. The TCJA also includes provisions that reduce the tax rates applicable to individuals and that treat dividends paid to REIT shareholders as income eligible for the new 20% deduction for business income earned from passthrough entities. These changes will have the effect of reducing the maximum income tax rate applicable to REIT dividends paid to individual REIT shareholders from 39.6% to 29.6%. These provisions, other than the reduction in the corporate federal income tax rate, are set to expire after 2025. The Company has recorded $55.8 million as a regulatory liability as of December 31, 2017 related to the creation of excess accumulated deferred federal income tax (ADFIT), related to the Company’s assets, due to the reduction in the corporate federal income tax rate. See Note 10, Regulatory Matters Revenue Recognition The Company, through its subsidiaries, is the owner of regulated assets and recognizes lease revenue over the term of lease agreements with Sharyland. The Company’s lease revenue includes annual payments and additional rents based upon a percentage of revenue earned by Sharyland on the leased assets in excess of annual specified breakpoints. In accordance with the lease agreements, Sharyland, the lessee and operator of the regulated assets, is responsible for the maintenance and operation of the regulated assets and primarily responsible for compliance with all regulatory requirements of the PUCT, the FERC or any other regulatory entity with jurisdiction over the regulated assets on the Company’s behalf and with the Company’s cooperation. Each of the lease agreements with Sharyland is a net lease that obligates the lessee to pay all property related expenses, including maintenance, repairs, taxes and insurance, and to comply with the terms of the SDTS secured credit facilities and note purchase agreements. The Company recognizes base rent under these leases on a straight-line basis over the applicable lease term. The current lease agreements provide for periodic supplemental adjustments of base rent based upon capital expenditures made by SDTS. The Company recognizes supplemental adjustments of base rent as a modification under these leases on a prospective straight-line basis over the applicable lease term. The Company recognizes percentage rent under these leases once the revenue earned by Sharyland on the leased assets exceeds the annual specified breakpoints. Asset Retirement Obligations The Company has identified, but not recognized, asset retirement obligation liabilities related to the regulated assets as a result of certain easements on property on which the Company has assets. Generally, such easements are perpetual and require only the retirement and removal of the assets upon cessation of the property’s use. Management has not estimated and recorded a retirement liability for such easements because the Company plans to use the facilities indefinitely. Interest Expense, net The Company’s interest expense, net primarily consists of interest expense from the senior secured notes, senior secured term loan and credit facilities, see Note 7, Borrowings Under Credit Facilities Long-Term Debt Other Income, net AFUDC on other funds of $0.7 million, $3.7 million and $3.0 million was recognized in other income, net during the years ended December 31, 2017, 2016 and 2015, respectively. Comprehensive Income Comprehensive income includes net income and other comprehensive income, which has consisted of unrealized gains and losses on derivative financial instruments. The Company records deferred hedge gains and losses on its derivative financial instruments that qualify as cash flow hedging instruments as other comprehensive income. For the years ended December 31, 2017, 2016 and 2015, net income and comprehensive income were the same amounts. The Company did not have any derivative financial instruments during 2017, 2016 or 2015. Fair Value of Financial Instruments ASC Topic 820, Fair Value Measurements and Disclosures Level 1 — Quoted prices in active markets for identical assets and liabilities. Level 2 — Valuations based on one or more quoted prices in markets that are not active; quoted prices for similar assets or liabilities in active markets; inputs that are observable other than quoted prices for the asset or the liability; or inputs that are derived principally from or corroborated by observable market data by correlation or other means. Level 3 — Valuations based on inputs that are unobservable and significant to the overall fair value measurement.
