As of June 30, 2018, the remaining authorization under our Board-approved share repurchase program was $325 million. There is no expiration date governing the period over which we can repurchase shares. Any repurchased shares are constructively retired and returned to an unissued status. The cost of stock repurchases is first charged to additional paid-in capital. Once additional paid-in capital is reduced to zero, any additional amounts are charged to (accumulated deficit) retained earnings.
