Common stock repurchases

On December 11, 2018, the Company adopted its common stock repurchase program, pursuant to which the Company was authorized to repurchase up to $250.0 million of its shares of common stock through December 31, 2019. All shares repurchased under the plan are retired upon settlement. The Company has elected to allocate the excess of the repurchase price over the par value of its common stock between APIC and retained earnings, with the portion allocated to APIC limited to the amount of APIC that was recorded at the time that the shares were initially issued, which is calculated on a last-in, first-out basis. The Company's common stock repurchase program was renewed through December 2020, authorizing the Company to repurchase up to an additional $250.0 million of its outstanding common stock.
