Retirement Benefits [Abstract]  
Post-Retirement Health Care Post-Retirement Health CareThe Corporation offers a fixed subsidy to certain retirees who choose to participate in a third party insurance plan selected by the Corporation. Guidance on employers’ accounting for other post-retirement plans requires recognition of the overfunded or underfunded status on the balance sheet. Under this guidance, gains and losses, prior service costs and credits, and any remaining transition amounts under previous guidance not yet recognized through net periodic benefit cost are recognized in accumulated other comprehensive income (loss), net of tax effects, until they are amortized as a component of net periodic benefit cost. Also, the measurement date – the date at which the benefit obligation and plan assets are measured – is required to be the Corporation’s fiscal year-end.
The following table sets forth the activity and reporting location of the benefit obligation and plan assets:
