As of April 30, 2018, we had 14.6 million shares reserved for future awards under our Plan.
We issue shares from our treasury stock to satisfy the exercise or vesting of stock-based awards and believe we have adequate treasury stock balances available for future issuances.
We measure the fair value of options on the grant date or modification date using the Black-Scholes-Merton (BlackScholes) option valuation model based upon the expected term of the options.
We measure the fair value of nonvested shares and share units based on the closing price of our common stock on the grant date.
We measure the fair value of performance-based share units based on the Monte Carlo valuation model, taking into account as necessary those provisions of the performance-based nonvested share units that are characterized as market conditions.
We generally expense the grant-date fair value, net of estimated forfeitures, over the vesting period on a straight-line basis.
Options, nonvested shares and nonvested share units (other than performance-based nonvested share units) granted to employees typically vest pro-rata based upon service over a three-year period with a portion vesting each year.
Performance-based nonvested share units granted to employees typically cliff vest at the end of a three-year period based upon satisfaction of both service-based and performance-based requirements.
The number of performance-based share units that ultimately vest can range from zero up to 250 percent of the number granted, based on the form of the award, which can vary by year of grant.
The performance metrics for these awards typically consist of earnings before interest, taxes, depreciation and amortization (EBITDA), EBITDA growth, return on equity, return on invested capital, total shareholder return or our stock price.
Deferred stock units granted to non-employee directors vest when they are granted and are settled six months after the director separates from service as a director of the Company, except in the case of death.
All share units granted to employees and non-employee directors receive cumulative dividend equivalents to the extent of the units ultimately vesting at the time of distribution.
Options granted under our Plan have a maximum contractual term of ten years.
NONVESTED SHARES AND SHARE UNITS – A summary of nonvested shares, nonvested share units and deferred stock units, including those that are performance-based, for the year ended April 30, 2018, is as follows:
## Table 0 ##
The total fair value of shares and units vesting during fiscal years 2018, 2017 and 2016 was $22.6 million, $20.3 million and $28.8 million, respectively.
As of April 30, 2018, we had $30.5 million of total unrecognized compensation cost related to these shares.
This cost is expected to be recognized over a weighted-average period of two years.
When valuing our performance-based nonvested share units on the grant date, we typically estimate the expected volatility using historical volatility for H&R Block, Inc.  and selected comparable companies.
The dividend yield is calculated based on the current dividend and the market price of our common stock on the grant date.
The risk-free interest rate is based on the U. S.  Treasury zero-coupon yield curve in effect on the grant date.
Both expected volatility and the risk-free interest rate are based on a period that approximates the expected term.
The following assumptions were used to value performance-based nonvested share units using the Monte Carlo valuation model during the periods:
CAF provides financing for qualified customers at competitive market rates of interest.
We securitize substantially all of the loans originated by CAF, as discussed in Note 5.
CAF income primarily reflects the interest and fee income generated by the auto loan receivables less the interest expense associated with the debt issued to fund these receivables, direct CAF expenses and a provision for estimated loan losses.
As described in Note 2(E), as of March 1, 2010, we adopted ASU Nos.2009-16 and 2009-17 on a prospective basis.
Prior to March 1, 2010, the majority of CAF income was typically generated by the spread between the interest rates charged to customers and the related funding cost for loans originated during the period.
A gain, recorded at the time of securitization, resulted from recording a receivable approximately equal to the present value of the expected residual cash flows generated by the securitized receivables.
The cash flows were calculated taking into account expected prepayments, losses and funding costs.
The gain on sales of loans originated and sold included both the gain income recorded at the time of securitization and the effect of any subsequent changes in valuation assumptions or funding costs that were incurred in the same fiscal period that the loans were originated.
Other gains or losses included the effects of changes in valuation assumptions or funding costs related to loans originated and sold during previous fiscal periods, the effects of new term securitizations and changes in the valuation of retained subordinated bonds, as applicable.
CAF income does not include any allocation of indirect costs or income.
We present this information on a direct basis to avoid making arbitrary decisions regarding the indirect benefits or costs that could be attributed to CAF.
Examples of indirect costs not included are retail store expenses and corporate expenses such as human resources, administrative services, marketing, information systems, accounting, legal, treasury and executive payroll.4.
AUTO LOAN RECEIVABLES Auto loan receivables include amounts due from customers primarily related to used retail vehicle sales financed through CAF and are presented net of an allowance for estimated loan losses.
We use warehouse facilities to fund auto loan receivables originated by CAF until they are funded through a term securitization or alternative funding arrangement.
The majority of these amounts serve as collateral for the related non-recourse notes payable of $4.68 billion as of February 29, 2012, and $4.01 billion as of February 28, 2011.
See Notes 5 and 11 for additional information on securitizations and non-recourse notes payable.

(1) Other receivables includes receivables not funded through the warehouse facilities or term securitizations.
Credit Quality.
When customers apply for financing, CAF uses proprietary scoring models that rely on the customers’ credit history and certain application information to evaluate and rank their risk.
Credit histories are obtained from credit bureau reporting agencies and include information such as number, age, type of and payment history for prior or existing credit accounts.
The application information that is used includes income, collateral value and down payment.
Our scoring models yield credit grades that represent the relative likelihood of repayment.
Customers assigned a grade of “A” are determined to have the highest probability of repayment, and customers assigned a lower grade are determined to have a lower probability of repayment.
For loans that are approved, the credit grade influences the terms of the agreement, such as the required loan-to-value ratio and interest rate.
CAF uses a combination of the initial credit grades and historical performance to monitor the credit quality of the auto loan receivables on an ongoing basis.
We validate the accuracy of the scoring models periodically.
