401
(k) Savings Plan
 
The Company has a tax-qualified employee savings and retirement plan, or
401
(k) plan. Under the
401

may
elect to reduce their current compensation, on a pre-tax basis, by up to
15%
of their taxable compensation or of the statutorily prescribed annual limit, whichever is lower, and have the amount of the reduction contributed to the
401
(k) plan. The
401
(k) plan permits the Company, in its sole discretion, to make additional employer contributions to the
401
(k) plan. However, the Company did
not
make employer contributions to the
401
(k) plan during any of the periods presented in the accompanying consolidated financial statements.
