The decision will be made within ninety (90) days after the Plan Administrator receives the claim unless the Plan Administrator determines additional time due to special circumstances is needed. If the Plan Administrator determines that an extension to process a claim is required, the final decision may be deferred up to one hundred eighty (180) days after the claim is received, if the claimant is notified in writing of the need for the extension and the anticipated date of a final decision before the end of the initial ninety (90) day period.

If the Plan Administrator decides that any individual who has claimed a right to receive benefits, or different benefits, under the Plan is not entitled to receive all or any part of the benefits claimed, it will inform the claimant in writing or electronically, in terms calculated to be understood by the claimant, of the specific reasons for the denial, the Plan provisions on which the denial is based, a description of additional material or information necessary to perfect the claim and an explanation of why the material or information is needed, and an explanation of the Plan’s claim review procedures.

The claimant, or his authorized representative, must file a written request for review with the Benefits Administrative Committee setting forth the grounds for the request and any supporting facts, comments or arguments he wishes to make, within sixty (60) days after actual or constructive notice. If a written request for review is not received within this sixty (60) day period, the denial will be final. The claimant shall have reasonable access to all relevant documents pertaining to the claim.

The Benefits Administrative Committee or the persons responsible to conduct the review on the Benefits Administrative Committee’s behalf shall conduct a full review of the claim. Unless special circumstances require an extension of the review period, the Benefits Administrative Committee will render its decision no later than the date of its next regularly scheduled meeting, unless the request is filed less than thirty (30) days before that meeting. If the request is filed less than thirty (30) days before a regularly scheduled meeting, the Benefits Administrative Committee will render its decision no later than the date of the second regularly scheduled meeting after it receives the request. However, if special circumstances require an extension of the review period, a final decision shall be rendered no later than the third regularly scheduled meeting after it receives the request for review, if the claimant is notified in writing of the special circumstances and the date of the expected decision, before the time is extended due to special circumstances. If the decision on review is not furnished to the claimant within the applicable time period(s), the claim shall be denied on the last day of the applicable period. Benefits Administrative Committee decisions shall be in writing. The decision shall include specific reasons for the action taken, including the specific Plan provisions on which the decision is based.
