Impact on 2009 Earnings from Adoption of FASB Staff Position APB 14-1
The company will provide guidance for 2009 performance in its fourth quarter 2008 earnings release in February 2009. At this time, it should be noted that the company’s earnings will be reduced by $0.03 to $0.04 per share by the mandatory adoption of FASB Staff Position APB 14-1, which requires companies to expense certain implied costs of the option value related to convertible debt beginning January 1, 2009. The company expects that FFO will be reduced by a similar amount. This non-cash charge will have no material impact on the company’s debt coverage ratios or debt covenants.
