For discussion of how the Personnel & Compensation Committee seeks to align pay with performance when making compensation decisions, see the “Compensation Discussion & Analysis” section of this proxy statement beginning on page 25. The following tables and related disclosures provide information about (i) the total compensation (SCT Total) of our principal executive officer (PEO) and the non-PEO named executive officers (Other NEOs) as presented in the Summary Compensation Table on page 40; (ii) the “compensation actually paid” (CAP) to our PEO and the Other NEOs, as calculated pursuant to Item 402(v) of Regulation S-K; (iii) certain financial performance measures; and (iv) the relationship of CAP to those financial performance measures.
