(2) There was a death or serious illness in your immediate family;
(3) Important records were destroyed or damaged by fire or other accidental cause;
(4) You were trying very hard to find necessary information to support your claim but did not find the information within the stated time period;
(5) Within the time limit for requesting further review, you asked us for additional information explaining our action, and within 60 days of receiving the explanation, you requested a review;
(6) We gave you incorrect or incomplete information about when and how to request administrative review or to file a civil suit;
(7) You did not receive notice of the determination or decision; or
(8) You sent the request to another Government agency in good faith within the time limit, and the request did not reach us until after the time period had expired.
