under this program , our management is authorized to purchase shares from time to time through open market purchases or privately negotiated transactions at prevailing prices as permitted by securities laws and other legal requirements , and subject to market conditions and other factors .
to facilitate repurchases , we make purchases pursuant to trading plans under rule 10b5-1 of the exchange act , which allows us to repurchase shares during periods when we otherwise might be prevented from doing so under insider trading laws or because of self-imposed trading blackout periods .
this program may be discontinued at any time .
