We continue to manage our property catastrophe exposure in order to provide our shareholders an acceptable return on the risks assumed in our property business and to reduce the variability of our earnings, while providing protection to our customers.
Our property business includes personal homeowners, commercial property and other property lines.
At December 31, 2009, we continue to be within our goal to have no more than a 1% likelihood of exceeding our expected annual aggregate catastrophe losses by $2 billion, net of reinsurance, from hurricanes and earthquakes, based on modeled assumptions and applications currently available.
The use of different assumptions and updates to industry models could materially change the projected loss.
Property catastrophe exposure management includes purchasing reinsurance in areas that have known exposure to hurricanes, earthquakes, wildfires, fires following earthquakes and other catastrophes.
We are working for changes in the regulatory environment, including recognizing the need for and improving appropriate risk based pricing and promoting the creation of government sponsored, privately funded solutions for mega-catastrophes.
While the actions that we take will be primarily focused on reducing the catastrophe exposure in our property business, we also consider their impact on our ability to market our auto lines.
Pricing of property products is typically intended to establish returns that we deem acceptable over a long-term period.
Losses, including losses from catastrophic events and weather-related losses (such as wind, hail, lightning and freeze losses not meeting our criteria to be declared a catastrophe) are accrued on an occurrence basis within the policy period.
Therefore, in any reporting period, loss experience from catastrophic events and weather-related losses may contribute to negative or positive underwriting performance relative to the expectations we incorporated into the products’ pricing.
Additionally, property products are more capital intensive than other personal lines products.
Allstate Protection outlook ?
Allstate Protection will emphasize attracting and retaining high lifetime value customers while maintaining pricing discipline.  ?
We expect that volatility in the level of catastrophes we experience will contribute to variation in our underwriting results; however, this volatility will be mitigated due to our catastrophe management actions, including the purchase of reinsurance.  ?
We will continue to study the efficiencies of our operations and cost structure for additional areas where costs may be reduced.
Premiums written, an operating measure, is the amount of premiums charged for policies issued during a fiscal period.
Premiums earned is a GAAP measure.
Premiums are considered earned and are included in the financial results on a pro-rata basis over the policy period.
The portion of premiums written applicable to the unexpired terms of the policies is recorded as unearned premiums on our Consolidated Statements of Financial Position.
Since the Allstate brand policy periods are typically 6 months for auto and 12 months for homeowners, and the Encompass standard auto and homeowners policy periods are typically 12 months and non-standard auto policy periods are typically 6 months, rate changes will generally be recognized in premiums earned over a period of 6 to 24 months.
The following table shows the unearned premium balance at December 31 and the timeframe in which we expect to recognize these premiums as earned.

(1) Other personal lines include commercial, condominium, renters, involuntary auto and other personal lines.
the vesting period to the date that the employee is eligible for retirement.
As of December 31, 2009, total unrecognized compensation cost related to all nonvested awards was $114 million, of which $73 million related to nonqualified stock options which are expected to be recognized over the weighted average vesting period of 2.50 years and $41 million is related to restricted stock units which are expected to be recognized over the weighted average vesting period of 2.49 years.
Options are granted under the plans at exercise prices equal to the fair value of the Company’s common stock on the applicable grant date.
The options granted under the Allstate plans generally vest ratably over a four-year period.
For directors, vesting is generally over a three-year period.
The options granted may be exercised once vested and will expire ten years after the date of grant unless the employee or director retires.
After retirement, employee stock options vest as scheduled.
For directors, vesting accelerates to the date of retirement.
When the options become vested, they may be exercised on or before the earlier of the option expiration date or the fifth anniversary of the employee’s or director’s retirement.
Restricted stock and restricted stock units generally vest and unrestrict in full on the fourth anniversary of the grant date, except for directors which vest immediately and unrestrict immediately after leaving the board.
The awards are subject to forfeiture upon termination.
For terminations due to retirement, shares continue to unrestrict as provided for in the original grant.
A total of 71.0 million shares of common stock were authorized to be used for awards under the plans, subject to adjustment in accordance with the plans’ terms.
At December 31, 2009, 25.1 million shares were reserved and remained available for future issuance under these plans.
The Company uses its treasury shares for these issuances.
The fair value of each option grant is estimated on the date of grant using a binomial lattice model.
The Company uses historical data to estimate option exercise and employee termination within the valuation model.
In addition, separate groups of employees that have similar historical exercise behavior are considered separately for valuation purposes.
The expected term of options granted is derived from the output of the binominal lattice model and represents the period of time that options granted are expected to be outstanding.
The expected volatility of the price of the underlying shares is implied based on traded options and historical volatility of the Company’s common stock.
The expected dividends for 2009 are based on a graded average of the current and historical long-term dividend yield of the Company’s stock as of the date of the grant.
The expected dividends for 2008 and 2007 were based on the current dividend yield of the Company’s stock as of the date of the grant.
The risk-free rate for periods within the contractual life of the option is based on the U. S.  Treasury yield curve in effect at the time of grant.
The assumptions used are shown in the following table.
