Organization and Basis of Presentation
NMI Holdings, Inc. (NMIH) is a Delaware corporation, incorporated in May 2011, to provide private mortgage guaranty insurance (which we refer to as mortgage insurance or MI) through its wholly owned insurance subsidiaries, National Mortgage Insurance Corporation (NMIC) and National Mortgage Reinsurance Inc One (Re One). In April 2012, we completed a private placement of our securities, through which we offered and sold an aggregate of 55,000,000 of our Class A common stock resulting in net proceeds of approximately $510 million (the Private Placement), and we completed the acquisition of our insurance subsidiaries for $8.5 million in cash, common stock and warrants, plus the assumption of $1.3 million in liabilities. In November 2013, we completed an initial public offering of 2.4 million shares of our common stock, and our common stock began trading on the NASDAQ exchange on November 8, 2013, under the symbol "NMIH."
In April 2013, NMIC, our primary insurance subsidiary, issued its first mortgage insurance policy. NMIC is licensed to write mortgage insurance in all 50 states and D.C. In August 2015, NMIH capitalized a wholly owned subsidiary, NMI Services, Inc. (NMIS), through which we offer outsourced loan review services on a limited basis to mortgage loan originators.
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements, which include the results of NMIH and its wholly owned subsidiaries, have been prepared in accordance with the instructions to Form 10-Q as prescribed by the SEC for interim reporting and include other information and disclosures required by accounting principles generally accepted in the U.S. (GAAP). Our accounts are maintained in U.S. dollars. These statements should be read in conjunction with our consolidated financial statements and notes thereto for the year ended December 31, 2015, included in our 2015 10-K. All intercompany transactions have been eliminated. The preparation of financial statements in accordance with GAAP requires management to make estimates and assumptions that affect reported amounts of assets and liabilities, as well as disclosure of contingent assets and liabilities as of the balance sheet date. Estimates also affect the reported amounts of income and expenses for the reporting period. Actual results could differ from those estimates. The results of operations for the interim period may not be indicative of the results that may be expected for the full year ending December 31, 2016.
Deferred Policy Acquisition Costs
Costs directly associated with the successful acquisition of mortgage insurance policies, consisting of certain selling expenses and other policy issuance and underwriting expenses, are initially deferred and reported as deferred policy acquisition costs (DAC). DAC is reviewed periodically to determine that it does not exceed recoverable amounts and is adjusted as appropriate for policy cancellations to be consistent with our revenue recognition policy. We estimate the rate of amortization to reflect actual experience and any changes to persistency or loss development. For each book year of business, these costs are amortized to expense in proportion to estimated gross profits over the estimated life of the policies. Total amortization of DAC for the nine months ended September 30, 2016 and 2015, net of a portion of ceding commission related to the 2016 QSR Transaction (see Note 5), was $3.4 million and $1.8 million, respectively.
Premium Deficiency Reserves
We consider whether a premium deficiency exists at each fiscal quarter using best estimate assumptions as of the testing date. Per Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 944, a premium deficiency reserve shall be recognized if the sum of expected claim costs and claim adjustment expenses, expected dividends to policyholders, unamortized acquisition costs and maintenance costs exceeds related unearned premiums and anticipated investment income. We have determined that no premium deficiency reserves were necessary for the nine months ended September 30, 2016 or 2015.
Reinsurance
We account for premiums, losses and loss expenses that are ceded to reinsurers on bases consistent with those we use to account for the original policies we issue and pursuant to the terms of our reinsurance contracts. We account for premiums ceded to reinsurers as reductions to premium revenue. We earn profit commissions, which represent a percentage of the profits recognized by the reinsurers that are returned to us, based on the level of losses ceded. We recognize any profit commissions we earn as increases in net premium revenue.
We receive ceding commissions, calculated as a percentage of ceded written premiums, which are intended to cover our costs to acquire and service the direct policies. We earn the ceding commissions in a manner consistent with our recognition of earnings on the underlying insurance policies, over the terms of the policies reinsured. We account for ceding commissions as reductions to underwriting and operating expenses.
We cede a portion of loss reserves, paid losses and loss expenses, which are accounted for as reductions to loss expense and as reinsurance recoverables. We remain directly liable for all loss payments in the event we are unable to collect from any reinsurer.

Recent Accounting Pronouncements
In May 2014, the FASB issued Accounting Standards Update (ASU) 2014-09, Revenue from Contracts with Customers (Topic 606). This update is intended to provide a consistent approach in recognizing revenue. In accordance with the new standard, recognition of revenue occurs when a customer obtains control of promised goods or services in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the new standard requires that reporting companies disclose the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. In August 2015, ASU 2015-14 deferred the provisions of ASU 2014-09 to be effective for interim and annual periods beginning after December 15, 2017. The Company is currently evaluating the impact the adoption of this ASU will have, if any, on the consolidated financial statements.
In August 2014, the FASB issued an update that requires an entity's management to evaluate whether there is substantial doubt about that entity's ability to continue as a going concern and, if so, disclose that fact. An entity's management will also be required to evaluate and disclose whether its plans alleviate that doubt. The guidance is effective for annual periods ending after December 15, 2016 and for interim and annual periods thereafter. We do not expect the adoption of this update to have a material effect on the presentation of our financial statements and notes therein.
In May 2015, the FASB issued ASU 2015-09, Disclosures about Short-Duration Contracts (Topic 944), which requires insurance entities to disclose additional information related to the liability for unpaid claims and claims adjustment expenses. These disclosures include the nature, amount, timing and uncertainty of cash flows related to those liabilities and the effects of those cash flows on comprehensive income. This update is effective for annual periods beginning after December 15, 2015 and interim periods within annual periods beginning after December 15, 2016. We do not expect the adoption of this update to have a material effect on the presentation of our financial statements and notes therein.
In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842). This update requires that businesses recognize rights and obligations associated with certain leases as assets and liabilities on the balance sheet. The standard also requires additional disclosures regarding the amount, timing, and uncertainty of cash flows arising from leases.  For public business entities, this update is effective for annual periods beginning after December 15, 2018, and interim periods therein. Early adoption is permitted in any period. The Company is currently evaluating the impact the adoption of this ASU will have on the consolidated financial statements.
In March 2016, the FASB issued ASU 2016-09, Compensation-Stock Compensation (Topic 718). This update is intended to provide improvements to employee share-based payment accounting. The areas for simplification in the update involve several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public business entities, the amendments in this update are effective for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Early adoption is permitted in any period. The Company is currently evaluating the impact the adoption of this ASU will have on the consolidated financial statements.
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326). This update requires companies to measure all expected credit losses for financial assets held at the reporting date. The accounting for credit losses on available-for-sale debt securities and purchased financial assets with credit deterioration also is amended in the standard. The standard will take effect for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2019. The Company is currently evaluating the impact the adoption of this ASU will have on the presentation of the consolidated financial statements.
In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230). This update is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The standard will take effect for public business entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. The Company is currently evaluating the impact the adoption of this ASU will have on the presentation of the consolidated financial statements.
