Statement of Stockholders' Equity [Abstract]  
Stockholders' Equity Equity
We have a stock repurchase program with 6.9 million shares remaining authorized for repurchase as of December 31, 2019. There were no shares repurchased in the open market during the year ended December 31, 2019, 1.4 million in 2018, and none in 2017. Repurchases are expected to continue from time to time, as determined by market conditions, cash flow requirements, securities law limitations, and other factors, until the number of shares authorized have been repurchased, or until the authorization is terminated. The share repurchase authorization is discretionary and has no expiration date.

During the years ended December 31, 2019, 2018 and 2017 our Board of Directors declared regular quarterly dividends totaling $6.6 million, $6.6 million, and $6.7 million for each year, respectively.  Future payment of cash dividends and the amount of such dividends will depend upon our financial conditions, our results of operations, our cash requirements, our tax treatment, and certain corporate law requirements, as well as factors deemed relevant by our Board of Directors.
