Employee Stock Purchase Plan
The Sara Lee Employee Stock Purchase Plan (ESPP) permitted eligible full-time employees to purchase a limited number of shares of Sara Lees common stock at 85% of market value. In November 2005 Sara Lee eliminated the 15% discount on shares acquired through the ESPP. Purchases after that date under the ESPP plan are at the fair value of the shares. Under the plan, Sara Lee sold 228,383 and 448,774 shares to Company employees during the thirty-nine weeks ended April 1, 2006 and fiscal 2005, respectively. Compensation expense is calculated for the fair value of the employees purchase rights using the Black-Scholes model. Assumptions include an expected life of 1/4 of a year and weighted average risk-free interest rates of 3.7% in the thirty-nine weeks ended April 1, 2006 and 2.3% in fiscal 2005. Other underlying assumptions are consistent with those used for Sara Lees stock option plans described above. The weighted average fair value of individual options granted year to date fiscal 2006 and fiscal 2005 were $3.48 and $4.06, respectively.
