(for 5.1 Recommended Criteria & Thresholds for Action for Potential NEO Impact Threat)

	o  Workshop held at NASA Ames Research Center (7-9 July 2015) on potentially hazardous asteroids (PHAs) that examined the 1) characterization, 2) atmospheric entry and 3) risk assessment.  Purpose of the workshop and the follow-on efforts is to advance our understanding of asteroid atmospheric entry/breakup; provide risk assessments of surface impact (land and water/tsunami); and characterization of PHA pre-entry properties.  This characterization aspect includes size, composition (i.e., stony, metallic, etc.), velocity, and trajectory of a potential impending PHA impact.  The long-term goal of this effort is to develop reasonably reliable predictive tools (i.e., the dependence of surface damage to PHA size and impact trajectory) to better enable decision-makers to determine appropriate mitigation steps in the event of an impending impact.

	o  Establishing the criteria and thresholds for action for a potential NEO impact threat will be an agenda item on the forthcoming IAWN meeting on 8 November 2015 (in concert with DPS at National Harbor in Washington, DC).

(for 5.4 Develop Communication Guidelines (in the case of a credible threat identified by IAWN)

	o Efforts have been made to present [and socialize] IAWN at PDC (April 2015 in Frascati), SBAG (June 2015 in Washington), and recent PHA Entry workshop (July 2015 at Ames Research Center at Moffett Field, California).

	o Development of the communication guidelines by IAWN (in the event of an actual potential impact threat) is also an agenda item for the next IAWN Steering Committee meeting at DPS (8 November 2015).
