Summary of Significant Accounting Policies |
Fair value measurements In accordance with fair value 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 certain U.S. Treasury securities and obligations of U.S. government corporations and agencies and Australian government and semi government securities. Level 2 – Quoted prices for similar instruments in active markets; 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 financial instrument. The observable inputs are used in valuation models to calculate the fair value of the financial instruments. Financial assets utilizing Level 2 inputs primarily include certain municipal and corporate bonds. Level 3 – Valuations derived from valuation techniques in which one or more significant inputs or value drivers are unobservable. Level 3 inputs reflect our own assumptions about the assumptions a market participant would use in pricing an asset or liability. Financial assets utilizing Level 3 inputs include certain state and auction rate (backed by student loans) securities. Non-financial assets which utilize Level 3 inputs include real estate acquired through claim settlement. 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. Quality controls are performed by the independent pricing sources throughout this process, which include reviewing tolerance reports, trading information and data changes, and directional moves compared to market moves. This model combines all inputs to arrive at a value assigned to each security. In addition, on a quarterly basis, we perform quality controls over values received from the pricing sources which include reviewing tolerance reports, trading information and data changes, and directional moves compared to market moves. We have not made any adjustments to the prices obtained from the independent pricing sources. Assets classified as Level 3 are as follows:
The spread for liquidity risk at December 31, 2012 increased significantly from September 30, 2012, due to our decision to consider offers from outside the auction process on our remaining two auction rate securities. These secondary market transactions have historically had a higher discount to par than transactions associated with the issuers or trustees.
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 accordance with applicable guidance. In evaluating whether a decline in fair value is other-than-temporary, we consider several factors including, but not limited to:
Home office and equipment
Deferred Insurance Policy Acquisition Costs
Loss Reserves Reserves are established for reported insurance losses and loss adjustment expenses based on when we receive notices of default on insured mortgage loans. We define a default as an insured loan with a mortgage payment that is 45 days or more past due. Reserves are also established for estimated losses incurred on notices of default not yet reported to us. Even though the accounting standard, Accounting Standards Codification ("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.
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 was based upon our pre-tax investment yield at year-end. Products are grouped for premium deficiency purposes based on similarities in the way the products are acquired, serviced and measured for profitability. Calculations of premium deficiency reserves require 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 present value of future premium relies on, among other factors, assumptions about persistency and repayment patterns on underlying loans. The present value 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. Assumptions used in calculating the deficiency reserves can be affected by volatility in the current housing and mortgage lending industries and these effects could be material. 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. (See Note 10 - "Premium Deficiency Reserve.") Revenue Recognition We write policies which are guaranteed renewable contracts at the insured's option on a single, annual or monthly premium basis. We have no ability to reunderwrite or reprice these contracts. Premiums written on a single premium basis and an annual premium basis are initially deferred as unearned premium reserve and earned over the policy term. Premiums written on policies covering more than one year are amortized over the policy life in accordance with the expiration of risk which is the anticipated claim payment pattern based on historical experience. Premiums written on annual policies are earned on a monthly pro rata basis. Premiums written on monthly policies are earned as coverage is provided. When a policy is cancelled, all premium that is non-refundable is immediately earned. Any refundable premium is returned to the lender. Cancellations include rescissions and policies cancelled due to claim payment. When a policy is rescinded, all previously collected premium is returned to the lender and when 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 separate components of this liability are included in "Other liabilities" and "Premium deficiency reserves" on our consolidated balance sheet. 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.
Income Taxes
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
Reinsurance
Foreign Currency Translation Assets and liabilities denominated in a foreign currency are translated at the year-end exchange rates. Operating results are translated at average rates of exchange prevailing during the year. Unrealized gains and losses, net of deferred taxes, resulting from translation are included in accumulated other comprehensive income in stockholders' equity. Gains and losses resulting from transactions in a foreign currency are recorded in current period net income at the rate on the transaction date. 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 five years. (See Note 18 – "Share-based Compensation Plans.") Earnings per Share Our basic EPS is based on the weighted average number of common shares outstanding, which excludes participating securities (with non-forfeitable rights to dividends) of 1.1 million, 1.1 million and 1.8 million, respectively, for the years ended December 31, 2012, 2011 and 2010 because they were anti-dilutive due to our reported net loss. Typically, diluted EPS is based on the weighted average number of common shares outstanding plus common stock equivalents which include certain stock awards, stock options and the dilutive effect of our convertible debt. In accordance with accounting guidance, if we report a net loss from continuing operations, then our diluted EPS is computed in the same manner as the basic EPS. In addition, if any common stock equivalents are anti-dilutive they are always excluded from the calculation. The following is a reconciliation of the weighted average number of shares; for the years ended December 31, 2012, 2011 and 2010, common stock equivalents of 61.7 million, 55.6 million and 47.4 million, respectively, were not included because they were anti-dilutive.
Other Comprehensive Income Our other comprehensive income for the years ended December 31, 2012, 2011 and 2010 was as follows:
See Note 14 – "Income Taxes" for a discussion of the valuation allowance. Our total accumulated other comprehensive income was as follows:
Cash and Cash Equivalents We consider money market funds and investments with original maturities of three months or less to be cash equivalents. Subsequent Events We have considered subsequent events through the date of this filing. |
