Chesapeake requested the recovery of approximately $34.2 million in acquisition premium and $2.2 million in merger-related costs Chesapeake had to satisfy the PSC's five-factor test In January of 2012, the Public Service Commission approved recovery of the acquisition premium and merger-related costs. As a result of the approval: We will be able to include the acquisition premium and merger-related costs in our cost and investment, when determining our rates for service Amortization expense will be recorded and also included in the calculation of our rates Acquisition premium amortized over 30 years Merger-related costs amortized over 5 years Amortization expense of : $2.4 million annually ($1.4 million, net of tax in 2012 and 2013) $2.3 million ($1.4 million, net of tax in 2014) $1.8 million ($1.1 million, net of tax annually thereafter until 2039) Longer-term, the inclusion of the acquisition premium in the Company's rate base and the recovery of the acquisition premium and merger-related costs through amortization expense, will increase the Company's earnings and cash flows above the levels that would have otherwise been achieved No recovery would have meant lower earnings.
