Implementation guidance, straight from the source

Both the IASB and the FASB have announced webinars to assist preparers in implementing the new lease accounting standards. The IASB has just posted a web presentation on The Transition to IFRS 16 (focused on transitioning operating leases, and primarily using the cumulative catch-up approach, rather than full retrospective application), along with additional transition/implementation materials available (and soon to be released) shown here.
The FASB will have a webinar on ASC 842 on Tuesday, March 29, 2016, 1-2 PM Eastern time. 1.0 CPE credit hours are offered for CPAs who register. These webinars are typically archived for later viewing, though CPE credit is not available then.
