Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2016

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"), as codified in the Accounting Standards Codification ("ASC"). Our consolidated financial statements include the accounts of MGIC Investment Corporation and its majority-owned subsidiaries. Intercompany transactions and balances have been eliminated. In accordance with GAAP, we are required to make estimates and assumptions that affect 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 revenues and expenses during the reporting periods. Actual results could differ from those estimates. We have considered subsequent events through the date of this filing.

Reclassifications

Certain reclassifications to 2015 and 2014 amounts have been made in the accompanying consolidated financial statements to conform to the 2016 presentation.

Cash and Cash Equivalents

We consider money market funds and investments with original maturities of three months or less to be cash equivalents.

Fair value measurements

The authoritative guidance around fair value established a framework for measuring fair value. Fair value is disclosed using a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value and includes Levels 1, 2, and 3. To determine the fair value of securities available-for-sale in Level 1 and Level 2 of the fair value hierarchy, independent pricing sources have been utilized. One price is provided per security based on observable market data. To ensure securities are appropriately classified in the fair value hierarchy, we review the pricing techniques and methodologies of the independent pricing sources and believe that their policies adequately consider market activity, either based on specific transactions for the issue valued or based on modeling of securities with similar credit quality, duration, yield and structure that were recently traded. A variety of inputs are utilized by the independent pricing sources including benchmark yields, reported trades, non-binding broker/dealer quotes, issuer spreads, two sided markets, benchmark securities, bids, offers and reference data including data published in market research publications. Inputs may be weighted differently for any security, and not all inputs are used for each security evaluation.

Market indicators, industry and economic events are also considered. This information is evaluated using a multidimensional pricing model. This model combines all inputs to arrive at a value assigned to each security. Quality controls are performed by the independent pricing sources throughout this process, which include reviewing tolerance reports, trading information, data changes, and directional moves compared to market moves. In addition, on a quarterly basis, we perform quality controls over values received from the pricing sources which also include reviewing tolerance reports, trading information, data changes, and directional moves compared to market moves. We have not made any adjustments to the prices obtained from the independent pricing sources.

In accordance with fair value accounting guidance, we applied the following fair value hierarchy in order to measure fair value for assets and liabilities:

Level 1 - Quoted prices for identical instruments in active markets that we can access. Financial assets utilizing Level 1 inputs primarily include U.S. Treasury securities, equity securities, and Australian government and semi government securities.

Level 2 - Quoted prices for similar instruments in active markets that we can access; quoted prices for identical or similar instruments in markets that are not active; and inputs, other than quoted prices, that are observable in the marketplace for the instrument. The observable inputs are used in valuation models to calculate the fair value of the instruments. Financial assets utilizing Level 2 inputs primarily include obligations of U.S. government corporations and agencies, corporate bonds, mortgage-backed securities, asset-backed securities, and most municipal bonds.

The independent pricing sources utilize these approaches to determine the fair value of the instruments in Level 2 of the fair value hierarchy based on type of instrument:

Corporate Debt & U.S. Government and Agency Bonds are evaluated by surveying the dealer community, obtaining relevant trade data, benchmark quotes and spreads and incorporating this information into the evaluation process.

Obligations of U.S. States & Political Subdivisions are evaluated by tracking, capturing, and analyzing quotes for active issues and trades reported via the Municipal Securities Rulemaking Board records. Daily briefings and reviews of current economic conditions, trading levels, spread relationships, and the slope of the yield curve provide further data for evaluation.

Residential Mortgage-Backed Securities ("RMBS") are evaluated by monitoring interest rate movements, and other pertinent data daily. Incoming market data is enriched to derive spread, yield and/or price data as appropriate, enabling known data points to be extrapolated for valuation application across a range of related securities.

Commercial Mortgage-Backed Securities ("CMBS") are evaluated using valuation techniques that reflect market participants’ assumptions and maximize the use of relevant observable inputs including quoted prices for similar assets, benchmark yield curves and market corroborated inputs. Evaluation utilizes regular reviews of the inputs for securities covered, including executed trades, broker quotes, credit information, collateral attributes and/or cash flow waterfall as applicable.

Asset-Backed Securities ("ABS") are evaluated using spreads and other information solicited from market buy-and-sell-side sources, including primary and secondary dealers, portfolio managers, and research analysts. Cash flows are generated for each tranche, benchmark yields are determined, and deal collateral performance and tranche level attributes including trade activity, bids, and offers are applied, resulting in tranche specific prices.

Collateralized loan obligations ("CLO") Collateralized Loan Obligations are evaluated by manager rating, seniority in the capital structure, assumptions about prepayment, default and recovery and their impact on cash flow generation. Loan level net asset values are determined and aggregated for tranches and as a final step prices are checked against available recent trade activity.

Level 3 - Valuations derived from valuation techniques in which one or more significant inputs or value drivers are unobservable or from par values for equity securities restricted in their ability to be redeemed or sold. The inputs used to derive the fair value of Level 3 securities reflect our own assumptions about the assumptions a market participant would use in pricing an asset or liability. Financial assets utilizing Level 3 inputs primarily include equity securities that can only be redeemed or sold at their par value and only to the security issuer and certain state premium tax credit investments. Our non-financial assets that are classified as Level 3 securities consist of real estate acquired through claim settlement. The fair value of real estate acquired is the lower of our acquisition cost or a percentage of the appraised value. The percentage applied to the appraised value is based upon our historical sales experience adjusted for current trends.

Investments

Our entire investment portfolio is classified as available-for-sale and is reported at fair value or, for certain equity securities carried at cost, amounts that approximate fair value. The related unrealized investment gains or losses are, after considering the related tax expense or benefit, recognized as a component of accumulated other comprehensive income (loss) in shareholders' equity. Realized investment gains and losses are reported in income based upon specific identification of securities sold. (See Note 5 – “Investments.”)

Each quarter we perform reviews of our investments in order to determine whether declines in fair value below amortized cost were considered other-than-temporary. In evaluating whether a decline in fair value is other-than-temporary, we consider several factors including, but not limited to:


▪	our intent to sell the security or whether it is more likely than not that we will be required to sell the security before recovery of its amortized cost basis;


▪	the present value of the discounted cash flows we expect to collect compared to the amortized cost basis of the security;


▪	extent and duration of the decline;


▪	failure of the issuer to make scheduled interest or principal payments;


▪	change in rating below investment grade; and


▪	adverse conditions specifically related to the security, an industry, or a geographic area.

Based on our evaluation, we will record an other-than-temporary impairment ("OTTI") adjustment on a security if we intend to sell the impaired security, if it is more likely than not that we will be required to sell the impaired security prior to recovery of its amortized cost basis, or if the present value of the discounted cash flows we expect to collect is less than the amortized cost basis of the security. If the fair value of a security is below its amortized cost at the time of our intent to sell, the security is classified as other-than-temporarily impaired and the full amount of the impairment is recognized as a loss in the statement of operations. Otherwise, when a security is considered to be other-than-temporarily impaired, the losses are separated into the portion of the loss that represents the credit loss and the portion that is due to other factors. The credit loss portion is recognized as a loss in the statement of operations, while the loss due to other factors is recognized in accumulated other comprehensive loss, net of taxes. A credit loss is determined to exist if the present value of the discounted cash flows, using the security’s original yield, expected to be collected from the security is less than the cost basis of the security.

Home office and equipment

Home office and equipment is carried at cost net of depreciation. For financial reporting purposes, depreciation is determined on a straight-line basis for the home office and equipment over estimated lives ranging from 3 to 45 years. For income tax purposes, we use accelerated depreciation methods.

Deferred Insurance Policy Acquisition Costs

Costs directly associated with the successful acquisition of mortgage insurance business, consisting of employee compensation and other policy issuance and underwriting expenses, are initially deferred and reported as deferred insurance policy acquisition costs ("DAC"). The deferred costs are net of any ceding commissions received associated with our reinsurance agreements. For each underwriting year of business, these costs are amortized to income in proportion to estimated gross profits over the estimated life of the policies. We utilize anticipated investment income in our calculation. This includes accruing interest on the unamortized balance of DAC. The estimates for each underwriting year are reviewed quarterly and updated when necessary to reflect actual experience and any changes to key variables such as persistency or loss development. If a premium deficiency exists (in other words, no gross profit is expected), we reduce the related DAC by the amount of the deficiency or to zero through a charge to current period earnings. If the deficiency is more than the related DAC balance, we then establish a premium deficiency reserve equal to the excess, through a charge to current period earnings.

Loss Reserves

Reserves are established for insurance losses and loss adjustment expenses ("LAE") when we receive notices of default on insured mortgage loans. We consider a loan in default when it is two or more payments past due. Even though the accounting standard, ASC 944, regarding accounting and reporting by insurance entities specifically excludes mortgage insurance from its guidance relating to loss reserves, we establish loss reserves using the general principles contained in the insurance standard. However, consistent with industry standards for mortgage insurers, we do not establish loss reserves for future claims on insured loans which are not currently in default. Loss reserves are established by estimating the number of loans in our inventory of delinquent loans that will result in a claim payment, which is referred to as the claim rate, and further estimating the amount of the claim payment, which is referred to as claim severity. Our loss estimates are established based upon historical experience, including rescission and loan modification activity. Adjustments to reserve estimates are reflected in the financial statements in the years in which the adjustments are made. The liability for reinsurance assumed is based on information provided by the ceding companies.

Reserves are also established for estimated losses from defaults occurring prior to the close of an accounting period on notices of default not yet reported to us. These incurred but not reported ("IBNR") reserves are also established using estimated claim rates and claim severities.

Reserves are also established for the estimated costs of settling claims, including legal and other expenses and general expenses of administering the claims settlement process. Reserves are also ceded to reinsurers under our reinsurance agreements.

Premium Deficiency Reserve

After our loss reserves are initially established, we perform premium deficiency tests using our best estimate assumptions as of the testing date. Premium deficiency reserves are established, if necessary, when the present value of expected future losses and expenses exceeds the present value of expected future premium and already established reserves. The discount rate used in the calculation of the premium deficiency reserve is based upon our pre-tax investment yield at year-end. Products are grouped for premium deficiency testing purposes based on similarities in the way the products are acquired, serviced and measured for profitability.

The calculation of premium deficiency reserves requires the use of significant judgments and estimates to determine the present value of future premium and present value of expected losses and expenses on our business. The calculation of future premium depends on, among other things, assumptions about persistency and repayment patterns on underlying loans. The calculation of expected losses and expenses depends on assumptions relating to severity of claims and claim rates on current defaults, and expected defaults in future periods. These assumptions also include an estimate of expected rescission activity. Similar to our loss reserve estimates, our estimates for premium deficiency reserves could be adversely affected by several factors, including a deterioration of regional or economic conditions leading to a reduction in borrowers' income and thus their ability to make mortgage payments, and a drop in housing values can influence the willingness of borrowers with sufficient resources to make mortgage payments to do so when the mortgage balance exceeds the value of the home, which could expose us to greater losses. Assumptions used in calculating the deficiency reserves can also be affected by volatility in the current housing and mortgage lending industries. To the extent premium patterns and actual loss experience differ from the assumptions used in calculating the premium deficiency reserves, the differences between the actual results and our estimate will affect future period earnings and could be material.

We previously established a premium deficiency reserve in 2007 on our Wall Street Bulk business, which we also ceased writing in that year. As of December 31, 2015 a premium deficiency reserve was no longer required. Changes in the premium deficiency reserve from period to period were primarily due to the recognition of previously estimated premiums, losses, and expenses, and changes in our assumptions relating to the present value of expected future premiums, losses, and expenses on the remaining Wall Street Bulk IIF. Our consolidated statements of operations for the years ended December 31, 2015 and 2014 were affected by decreases in our premium deficiency reserves of $24 million and $25 million, respectively. The decreases represented the net result of actual premiums, losses and expenses as well as a net change in assumptions for these periods.

Revenue Recognition

We write policies which are guaranteed renewable contracts at the insured's option on a monthly, single, or annual premium basis. We have no ability to reunderwrite or reprice these contracts. Premiums written on monthly premium policies are earned as coverage is provided. Premiums written on single premium policies and annual premium policies are initially deferred as unearned premium reserve and earned over the estimated policy life. Premiums written on policies covering more than one year are amortized over the policy life in relationship to the anticipated incurred loss pattern based on historical experience. Premiums written on annual premium policies are earned on a monthly pro rata basis. When a policy is cancelled for a reason other than rescission or claim payment, all premium that is non-refundable is immediately earned. Any refundable premium is returned to the servicer or borrower. When a policy is cancelled due to rescission, all previously collected premium is returned to the servicer and when a policy is cancelled because a claim is paid, we return any premium received since the date of default. The liability associated with our estimate of premium to be returned is accrued for separately and included in "Other liabilities" on our consolidated balance sheets. When a premium deficiency exists the premium refund liability is included in “Premium deficiency reserves” on our consolidated balance sheets. Changes in these liabilities affect premiums written and earned and change in premium deficiency reserve, respectively. The actual return of premium for all periods affects premiums written and earned. Policy cancellations also lower the persistency rate which is a variable used in calculating the rate of amortization of deferred insurance policy acquisition costs.

Fee income of our non-insurance subsidiaries is earned and recognized as the services are provided and the customer is obligated to pay. Fee income consists primarily of contract underwriting and related fee-based services provided to lenders and is included in “Other revenue” on the consolidated statements of operations.

Income Taxes

Deferred income taxes are provided under the liability method, which recognizes the future tax effects of temporary differences between amounts reported in the consolidated financial statements and the tax bases of these items. The expected tax effects are computed at the enacted regular federal statutory tax rate. Using this method, we have recorded a net deferred tax asset primarily due to net operating losses incurred in prior years. On a quarterly basis, we review the need to maintain a deferred tax asset valuation allowance as an offset to the net deferred tax asset, before valuation allowance. We analyze several factors, among which are the severity and frequency of operating losses, our capacity for the carryback or carryforward of any losses, the existence and current level of taxable operating income, operating results on a three year cumulative basis, the expected occurrence of future income or loss, the expiration dates of the carryforwards, the cyclical nature of our operating results, and available tax planning strategies. Based on our analysis, we reduced our benefit from income tax through the recognition of a valuation allowance from the first quarter of 2009 through the second quarter of 2015. In the third quarter of 2015, as discussed in Note 12 –“Income Taxes,” we concluded that it was more likely than not that our deferred tax assets would be fully realizable and we reversed the valuation allowance.

We provide for uncertain tax positions and the related interest and penalties based on our assessment of whether a tax benefit is more likely than not to be sustained under any examination by taxing authorities.

Benefit Plans

We have a non-contributory defined benefit pension plan covering substantially all employees, as well as a supplemental executive retirement plan. Retirement benefits are based on compensation and years of service. We recognize these retirement benefit costs over the period during which employees render the service that qualifies them for benefits. Our policy is to fund pension cost as required under the Employee Retirement Income Security Act of 1974.

We offer both medical and dental benefits for retired domestic employees, their eligible spouses and dependents until the retiree reaches the age of 65. Under the plan retirees pay a premium for these benefits. We accrue the estimated costs of retiree medical and dental benefits over the period during which employees render the service that qualifies them for benefits.

Reinsurance

Loss reserves and unearned premiums are reported before taking credit for amounts ceded under reinsurance agreements. Ceded loss reserves are reflected as "Reinsurance recoverable on loss reserves." Ceded unearned premiums are included in “Other assets.” Amounts due from reinsurers on paid claims are reflected as “Reinsurance recoverable on paid losses.” Ceded premiums payable are included in “Other liabilities.” Any profit commissions are included with “Premiums written – Ceded” and any ceding commissions are included with “Other underwriting and operating expenses, net.” We remain liable for all insurance ceded.

Share-Based Compensation

We have certain share-based compensation plans. Under the fair value method, compensation cost is measured at the grant date based on the fair value of the award and is recognized over the service period which generally corresponds to the vesting period. The fair value of awards classified as liabilities is remeasured at each reporting period until the award is settled. Awards under our plans generally vest over periods ranging from one to three years.

Earnings per Share

Basic earnings per share ("EPS") is calculated by dividing net income by the weighted average number of shares of common stock outstanding. Diluted EPS includes the components of basic EPS and also gives effect to dilutive common stock equivalents. We calculate diluted EPS using the treasury stock method and if-converted method. Under the treasury stock method, diluted EPS reflects the potential dilution that could occur if our unvested restricted stock units result in the issuance of common stock. Under the if-converted method, diluted EPS reflects the potential dilution that could occur if our convertible debt instruments result in the issuance of common stock. The determination of potentially issuable shares does not consider the satisfaction of the conversion requirements and the shares are included in the determination of diluted EPS as of the beginning of the period, if dilutive. We have several debt issuances that could result in contingently issuable shares and consider each potential issuance of shares separately to reflect the maximum potential dilution. Nonetheless, our dilutive common stock equivalents may not reflect all of the contingently issuable shares that could be required to be issued upon any debt conversion. For purposes of calculating basic and diluted EPS, vested restricted stock and restricted stock units ("RSUs") are considered outstanding.

Recent accounting and reporting developments



Standard	Summary of guidance		Effects on financial statements and/or disclosures

	•	If the performance target becomes probable of being achieved before the end of the service period, the remaining unrecognized compensation cost for which requisite service has not yet been rendered is recognized prospectively over the remaining service period.	•	For further information, see Note 15. "Share-based Compensation Plans".
Disclosures about Short-Duration Contracts	•	Requires expanded disclosures designed to provide additional insight into an insurance entity's ability to underwrite and anticipate costs associated with claims.	•	This standard is not considered applicable to our business and therefore we have not adopted these disclosure requirements.

Financial Accounting Standards Board ("FASB") Standards Issued but not yet Adopted
Standard	Summary of guidance		Effects on financial statements and/or disclosures
Recognition and Measurement of Financial Assets and Financial Liabilities Issued January 2016	•	Requires equity investments, except those accounted for under the equity method of accounting that have a readily determinable fair value to be measured at fair value with changes in fair value recognized in earnings.	•	Required effective date: January 1, 2018.
	•	Equity investments that do not have readily determinable fair values may be remeasured at fair value either upon the occurrence of an observable price change or upon identification of an impairment. A qualitative assessment for impairment is required for equity investments without readily determinable fair values.	•	The potential impact from the adoption of this guidance is not expected to have a material impact our consolidated balance sheets, consolidated statements of operations, or liquidity.
	•	Requires recognition of a cumulative effect adjustment to retained earnings as of the beginning of the reporting period of adoption.	•	For further information on our current equity investments see Note 5. "Investments."
Improvements to Employee Share-Based Compensation Accounting Issued March 2016	•	Requires that, prospectively, all tax effects related to share-based compensation be made through the statement of operations at the time of settlement, rather than recognizing excess tax benefits within paid-in capital.	•	Required effective date: January 1, 2017.
	•	Removes the requirement to delay recognition of a tax benefit until it reduces current taxes payable. This change is required to be applied on a modified retrospective basis.	•	We are currently evaluating the impacts the adoption of this guidance will have on our consolidated financial statements.
	•	Requires all tax related cash flows resulting from share-based compensation to be reported as operating activities, a change from the existing requirement to present tax benefits as an inflow from financing activities and an outflow from operating activities.
	•	Entities, for tax withholding purposes, will be allowed to withhold an amount of shares up to an employee's maximum individual tax rate (as opposed to the minimum statutory tax rate) in the relevant jurisdiction without resulting in liability classification of the award.
Measurement of Credit Losses on Financial Statements Issued June 2016	•	Requires immediate recognition of estimated credit losses expected to occur over the remaining life of many financial instruments. Entities are required to use a current expected credit loss ("CECL") methodology that incorporates their forecasts of future economic conditions, unless such forecast is not reasonable or supportable, in which case the entity will revert to historical loss experience.	•	Required effective date: January 1, 2020.
	•	Amends existing guidance for available-for-sale fixed income securities to incorporate an allowance, rather than a write-down of the asset, with the amount of the allowance limited to the amount by which the fair value is less than amortized cost. The guidance will allow for reversals of impairment losses in the event that the credit of an issuer improves. The length of time a security has been in an unrealized loss position will no longer impact the determination of whether a credit loss exists.	•	We are currently evaluating the impacts the adoption of this guidance will have on our consolidated financial statements, but do not expect it to have a material impact.
	•	Updated guidance is not prescriptive about certain aspects of estimating expected credit losses, including the specific methodology to use, and therefore will require significant judgment in application.
