Notes to Consolidated Financial Statements — (Continued) (Amounts in Millions, Except Per Share Amounts) facilities as of December 31, 2007 and 2006 was approximately 5% in each year.
A summary of our credit facilities is as follows:
## Table 0 ##
Our primary credit agreement is a $750.0 Three-Year Credit Agreement, dated as of June 13, 2006 (the “Credit Agreement”).
Under the Credit Agreement, a special-purpose entity called ELF Special Financing Ltd.  (“ELF”) acts as the lender and letter of credit issuer.
ELF is obligated at our request to make cash advances to us and to issue letters of credit for our account, in an aggregate amount not to exceed $750.0 outstanding at any time.
The aggregate face amount of letters of credit may not exceed $600.0 at any time.
Our obligations under the Credit Agreement are unsecured.
The Credit Agreement is a revolving facility, under which amounts borrowed may be repaid and borrowed again, and the aggregate available amount of letters of credit may decrease or increase, subject to the overall limit of $750.0 and the $600.0 limit on letters of credit.
We are not subject to any financial or other material restrictive covenants under the Credit Agreement.
We pay commitment fees on the undrawn amount, less the letters of credit, under the Credit Agreement at 0.78% per annum, and we pay commissions of 0.78% per annum on the amounts available to be drawn under the letters of credit.
In addition, we pay a facility fee equal to 0.15% per annum on the undrawn amount, including letters of credit, under the facility.
If we draw under the facility, interest is payable on any outstanding advances under the Credit Agreement at 3-month LIBOR plus 0.78% per annum.
The Credit Agreement will expire on June 15, 2009.
We entered into the Credit Agreement during the second quarter of 2006 as part of a transaction we refer to as the “ELF Financing.
” ELF is a special-purpose entity incorporated in the Cayman Islands, in which we have no equity or other interest and which we do not consolidate for financial reporting purposes.
In the ELF Financing, institutional investors purchased from ELF debt securities issued by ELF (the “ELF Notes”) and warrants issued by us (refer to Note 11).
ELF received $750.0 in proceeds from these sales, which it used to purchase AAA-rated liquid assets.
It will hold the liquid assets pending any request for borrowing from us or any drawing on any letters of credit issued for our account under the Credit Agreement, which ELF will fund by selling liquid assets.
We are not the issuer of the ELF Notes and are not party to the indenture governing the ELF Notes.
In conjunction with the ELF Financing we paid $41.2 of issuance costs, with the offset recorded in other assets.
The issuance costs consist of approximately $25.0 of underwriting commissions, legal and accounting fees, printing costs and other fees or expenses, with the balance in a fee to one of the initial purchasers for its services as structuring agent for the offering.
These costs will be amortized through the exercise date of the warrants on a straight-line basis as a component of interest expense.
During 2007, we amortized $13.7 of issuance costs.
Under certain circumstances, including certain events of default involving us or occurring under the ELF Notes, the commitment to make advances and issue letters of credit under the Credit Agreement may be terminated by ELF, acting on instruction of the holders of the ELF Notes.
We will be entitled, prior to any such termination, to make a borrowing of up to the entire available amount of the commitment under the Credit Agreement (regardless of whether our obligations under the Credit Agreement have been accelerated).
Upon termination of the commitment, the holders of the ELF Notes will automatically receive interests in the outstanding loans in exchang
Notes to Consolidated Financial Statements — (Continued) (Amounts in Millions, Except Per Share Amounts) in 2007, 2006 and 2005 was $3.0, $0.9 and $0.2, respectively.
As of December 31, 2007 there was $23.4 of total unrecognized compensation expense related to non-vested stock options granted, which is expected to be recognized over a weighted-average period of 2.4 years.
As of December 31, 2007, the aggregate intrinsic value for stock options outstanding, vested and expected to vest, exercisable and non-vested is zero.
We use the Black-Scholes option-pricing model to estimate the fair value of options granted, which requires the input of subjective assumptions including the option’s expected term and the price volatility of the underlying stock.
Changes in the assumptions can materially affect the estimate of fair value and our results of operations could be materially impacted.
The fair value of each option grant has been estimated with the following weighted-average assumptions:
## Table 1 ##
(1) The expected volatility for the second half of 2005 and the twelve months ended December 31, 2007 and 2006 used to estimate the fair value of stock options awarded is based on a blend of: (i) historical volatility of our common stock for periods equal to the expected term of our stock options and (ii) implied volatility of tradable forward put and call options to purchase and sell shares of our common stock.
For the first half of 2005, the expected volatility factor was based on historical volatility of our common stock over the most recent period commensurate with the estimated expected term of our stock options.
(2) The estimate of our expected term for the second half of 2005 and the twelve months ended December 31, 2007 and 2006 is based on the average of (i) an assumption that all outstanding options are exercised upon achieving their full vesting date and (ii) an assumption that all outstanding options will be exercised at the midpoint between the current date (i. e. , the date awards have ratably vested through) and their full contractual term.
In determining the estimate, we considered several factors, including the historical option exercise behavior of our employees and the terms and vesting periods of the options.
For the first half of 2005, our estimate of expected term was based on the historical patterns of exercises.
(3) The risk free rate is determined using the implied yield currently available for zero-coupon U. S.  government issuers with a remaining term equal to the expected term of the options.
(4) No dividend yield was assumed because we currently do not pay cash dividends on our common stock and have no current plans to reinstate a dividend.
Stock-Settled Awards Stock-settled awards include restricted stock and restricted stock units expected to be settled in stock.
They are granted to certain key employees and are subject to certain restrictions and vesting requirements as determined by the Compensation Committee.
The vesting period is generally three years.
No monetary consideration is paid by a recipient for a stock-settled award, and the fair value of the shares on the grant date is amortized over the vesting period.
During 2007, 2006 and 2005, we awarded 5.0, 5.3 and 4.6 shares of stock-settled awards with a weighted-average grant-date fair value of $11.68, $8.77 and $11.98 per award, respectively.
The total fair value of vested stock-settled awards that were distributed to participants during 2007, 2006 and 2005 was $41.5, $11.0 and $19.8, respectively.

Notes to Consolidated Financial Statements (continued) Management performs detailed reviews of its receivables on a monthly and/or quarterly basis to assess the adequacy of the allowances based on historical and current trends and other factors affecting credit losses and to determine if any impairment has occurred.
A receivable is impaired when it is probable that all amounts related to the receivable will not be collected according to the contractual terms of the agreement.
In circumstances where the company is aware of a specific customer’s inability to meet its financial obligations, a specific reserve is recorded against amounts due to reduce the net recognized receivable to the amount reasonably expected to be collected.
Additions to the allowances for doubtful accounts are maintained through adjustments to the provision for credit losses, which are charged to current period earnings; amounts determined to be uncollectable are charged directly against the allowances, while amounts recovered on previously charged-off accounts increase the allowances.
Net charge-offs include the principal amount of losses charged off as well as charged-off interest and fees.
Recovered interest and fees previously charged-off are recorded through the allowances for doubtful accounts and increase the allowances.
Finance receivables are assessed for chargeoff when an account becomes 120 days past due and are charged-off typically within 60 days of asset repossession.
Contract receivables related to equipment leases are generally charged-off when an account becomes 150 days past due, while contract receivables related to franchise finance and van leases are generally charged off up to 180 days past the asset return.
For finance and contract receivables, customer bankruptcies are generally charged-off upon notification that the associated debt is not being reaffirmed or, in any event, no later than 180 days past due.
Snap-on does not believe that its trade accounts, finance or contract receivables represent significant concentrations of credit risk because of the diversified portfolio of individual customers and geographical areas.
See Note 3 for further information on receivables and allowances for doubtful accounts.
