The measurement date for determining rate assumptions used in calculating the net periodic benefit cost (such as the weighted-average expected long-term rate of return on plan assets and the discount rate) is normally the beginning of the year measurement date. If an assumed rate(s) changes due to a subsequent interim measurement of both plan assets and obligations, disclosure of the beginning and more recently assumed rate(s), or a properly weighted combination of the two. Disclosure may include the more recent measurement date.
