The prior year development of $8.0 million for Tower, excluding the Reciprocal Exchanges, was primarily in our property and personal automobile lines of business and resulted from winter weather related claims. There was favorable prior year development of $6.2 million for the Reciprocal Exchanges which was a result of lower than anticipated claims emergence for both homeowners' and private passenger lines of business.Prior year development is based upon numerous estimates by line of business and accident year. No additional premiums or return premiums have been accrued as a result of the prior year effects, although we recorded changes in ceding commissions on reinsurance treaties that we purchase and for which the commissions depend in part on loss experience. The Company's management continually monitors claims activity to assess the appropriateness of carried case and incurred but not reported (“IBNR”) reserves, giving consideration to Company and industry trends.Incurred losses and LAE as of March 31, 2011 included a reduction of $1.4 million pertaining to the amortization of the reserve risk premium on loss reserves recorded in connection with the Company's acquisitions in prior years. Of this amount, $1.1 million and $0.3 million relate to Tower and the Reciprocal Exchanges, respectively. As of March 31, 2011 the unamortized reserves risk premium was $13.2 million, of which $9.8 million and $3.4 million, respectively, related to Tower and the Reciprocal Exchanges.Loss and loss adjustment expense reserves.   The reserving process for loss and LAE reserves provides for the Company's best estimate as of the balance sheet date of the ultimate unpaid cost of all losses and LAE incurred, including settlement and administration of losses, and is based on facts and circumstances then known and including losses that have been incurred but not yet been reported. The amount of loss and LAE reserves for reported claims is based primarily upon a case-by-case evaluation of coverage, liability, injury severity, and any other information considered pertinent to estimating the exposure presented by the claim. The amounts of loss and LAE reserves for unreported claims are determined using historical information by line of insurance as adjusted to current conditions. The difference between the paid claims and case outstanding loss estimates and management's best estimate of loss and LAE and reported losses is recorded in IBNR.The process includes using actuarial methodologies to assist in establishing these estimates, judgments relative to estimates of future claims severity and frequency, the length of time before losses will develop to their ultimate level and considerations of other factors such as law changes, economic conditions, and other external factors. The methods used to select the estimated loss reserves include loss ratio projections, loss development projections, and Bornhuetter-Ferguson (B-F) method projections. The actuaries' estimates are the result of numerous analyses made by line of business, accident year, and for loss, allocated LAE and unallocated LAE. Management sets the carried reserves based upon the actuaries' estimates of expected loss and LAE and other considerations about the underlying business that are not reflected in the actuarial indications. There is no explicit or implicit risk premium provision for uncertainty in the carried loss and LAE reserves, excluding the loss and LAE reserves assumed through business combinations in either 2010 or 2009. For business combinations after January 1, 2009, which included CastlePoint, Hermitage, SUA and OBPL, the liability for loss and LAE includes the fair value adjustment related to those acquisitions.Note 7—Loss and Loss Adjustment ExpenseThe following table provides a reconciliation of the beginning and ending balances for unpaid losses and LAE forfalsefalsefalsefalsefalseOtherus-types:textBlockItemTypestringDescribes the various components of the reserve for future policy benefits and guaranteed minimum benefits, and for claims and claims adjustment expenses; the significant assumptions for estimating claims losses; causes of significant variances from prior periods (such as catastrophes, asbestos and environmental claims reserve losses); and reconciliations of beginning to ending reserve balances.Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher AICPA -Name Statement of Position (SOP) -Number 94-5 -Paragraph 11 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher SEC -Name Regulation S-X (SX) -Number 210 -Section 03 -Paragraph 13 -Article 7 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Statement of Financial Accounting Standard (FAS) -Number 60 -Paragraph 60 falsefalseLoss and Loss Adjustment Expense12Loss and Loss Adjustment ExpenseUnKnownUnKnownUnKnownUnKnownfalsetrue
