What you need to know
You do not have a multiemployer plan. Since this paragraph does not apply to your plan, we removed this paragraph and have provided you a revised amendment. Full details can be found in the “Disability Claims Procedures” section of the plan amendment.

This amendment of the Plan is adopted to comply with the requirements of the final regulations under ERISA Section 503. This amendment is to be construed in accordance with such regulations. This amendment shall continue to apply to the Plan, including the Plan as later amended, until such provisions are integrated into the Plan or the provisions of this amendment are specifically amended.

This amendment shall supersede any previous amendment and the provisions of the Plan to the extent those provisions are inconsistent with the provisions of this amendment.

The provisions of this amendment shall be effective on April 1, 2018.

By striking the Disability Claim Procedures subsection of the CLAIM PROCEDURES SECTION of Article IX and substituting the following:

Disability Claim Procedures. If disability is not determined based on Title II of the Federal Social Security Act or in accordance with the terms of the Employer’s long-term disability plan, in the case of a claim for disability benefits, the above provisions will be modified as provided below.

The Plan Administrator shall ensure that all claims and appeals for disability benefits are adjudicated in a manner designed to ensure the independence and impartiality of the persons involved in making the decision. If a claim for disability benefits under the Plan is wholly or partially denied, the Plan Administrator shall provide adequate written notice to the Claimant whose claim for benefits under the Plan has been denied. The notice must be furnished within 45 days of the date that the claim is received by the Plan without regard to whether all of the information necessary to make a benefit determination is received. The period for furnishing the notice may be extended for up to 30 days if the Plan Administrator both determines an extension is necessary due to matters beyond the control of the Plan and notifies the Claimant in writing within this initial 45-day period. The notice shall indicate the circumstances requiring the extension of time and the date by which the Plan expects to render a decision. If prior to the end of the first 30-day extension period, the Plan Administrator determines that, due to matters beyond the control of the Plan, a decision cannot be rendered within that extension period, the period may be extended for up to an additional 30 days, provided the Plan Administrator notifies the Claimant in writing, within the first 30-day extension period, of the circumstances requiring the extension and the date by which the Plan expects to render a decision. In the case of any extension, the notice of extension shall specifically explain the standards on which entitlement to a benefit is based, the unresolved issues that prevent a decision on the claim, and the additional information needed 

to resolve those issues. The Claimant shall be afforded at least 45 days within which to provide the specified information.

In the event that a period of time is extended due to a Claimant’s failure to submit information necessary to decide a claim, the period for making the benefit determination shall be tolled from the date on which the notification of the extension is sent to the Claimant until the date on which the Claimant responds to the request for additional information.

The Plan Administrator's notice to the Claimant shall: (i) specify the reason or reasons for the denial; (ii) reference the specific Plan provisions on which the denial is based; (iii) describe any additional material and information needed for the Claimant to perfect his claim for benefits; (iv) explain why the material and information is needed; (v) inform the Claimant of the Plan’s appeal procedures and the time limits applicable to such procedures, including a statement of the Claimant’s right to bring a civil action under ERISA Section 502(a) following an adverse benefit determination on appeal; (vi) provide the Claimant with any internal rule, guideline, protocol, or other similar criteria that was relied upon in making the adverse determination or a statement that such rule, guideline, protocol, or other similar criteria of the Plan does not exist; and (vii) provide the Claimant with an explanation of any scientific or clinical judgment for the determination if benefit determination is based on a medical necessity or experimental treatment or similar exclusion or limit or a statement that the benefit is based on such an exclusion or limit and such explanation will be provided free of charge.

The notice shall also provide the Claimant with a discussion of the decision, including an explanation of the basis for disagreeing with or not following, (i) the views presented by the Claimant to the Plan of health care professionals treating the Claimant and vocational professionals who evaluated the Claimant; (ii) the views of medical or vocational experts whose advice was obtained on behalf of the Plan in connection with a Claimant's adverse benefit determination, without regard to whether the advice was relied upon in making the benefit determination; and (iii) a disability determination regarding the Claimant presented by the Claimant to the Plan made by the Social Security Administration.

The notice shall be provided in a culturally and linguistically appropriate manner and provide a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the Claimant's claim for benefits.

Any appeal made by a Claimant must be in writing to the Plan Administrator within 180 days after receipt of the Plan Administrator’s notice of denial of benefits. The Claimant may submit written comments, documents, records, and other information relating to the claim for benefits. The Claimant shall be provided, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the Claimant’s claim for benefits. The Plan Administrator shall review the claim taking into account all comments, documents, records, and other information submitted by the Claimant relating to the claim, without regard to whether such information was submitted or considered in the initial benefit determination. The review shall not afford deference to the initial adverse benefit determination and shall be conducted by an appropriate named fiduciary who is neither the individual who made the adverse benefit determination that is the subject of the appeal, nor the subordinate of such individual. If the adverse benefit determination is based in whole or in part on a medical judgment, the appropriate named fiduciary shall consult with a health care professional who has appropriate training and experience in the field of medicine involved in the medical judgment. Such health care professional shall be an individual who is neither an individual who was consulted in connection with the adverse benefit determination that is the subject of the appeal, nor the subordinate of such individual. The Claimant shall be provided with the identity of medical or vocational experts whose advice was obtained on behalf of the Plan in connection with the adverse benefit determination, without regard to whether the advice was relied on.

Before a claim for disability benefits is wholly or partially denied on review, the Plan Administrator shall provide the Claimant, free of charge, with any new or additional evidence considered, relied upon, or generated by the Plan, Insurer, or other person making the benefit determination (or at the direction of the Plan, Insurer or such other person) in connection with the claim; such evidence must be provided as soon 

as possible and sufficiently in advance of the date on which the notice that the claim for disability benefits is wholly or partially denied on review to give the Claimant a reasonable opportunity to respond prior to that
date; and provide before a claim for disability benefits is wholly or partially denied on review based on a new or additional rationale, the Plan Administrator shall provide the Claimant, free of charge, with the rationale; the rationale must be provided as soon as possible and sufficiently in advance of the date on which the notice that the claim for disability benefits is wholly or partially denied on review to give the Claimant a reasonable opportunity to respond prior to that date.

The Plan Administrator shall provide adequate written notice to the Claimant of the Plan’s benefit determination on review. The notice must be furnished within 45 days of the date that the request for review is received by the Plan without regard to whether all of the information necessary to make a benefit determination on review is received. The Claimant shall be notified in writing within this initial 45-day period if special circumstances require an extension of the time needed to process the claim. The notice shall indicate the special circumstances requiring an extension of time and the date by which the Plan Administrator expects to render the determination on review. In no event shall such extension exceed a period of 45 days from the end of the initial 45-day period.

To the extent that a period of time is extended due to a Claimant’s failure to submit information necessary to decide a claim, the period for making the benefit determination on review shall be tolled from the date on which the notification of the extension is sent to the Claimant until the date on which the Claimant responds to the request for additional information.

If the claim for disability benefits is wholly or partially denied on review, the Plan Administrator’s notice to the Claimant shall: (i) specify the reason or reasons for the denial; (ii) reference the specific Plan provisions on which the denial is based; (iii) include a statement that the Claimant is entitled to receive, upon request and free of charge, reasonable access to, and copies of, all documents, records, and other information relevant to the Claimant’s claim for benefits; (iv) include a statement of the Claimant’s right to bring a civil action under ERISA Section 502(a); (v) provide the Claimant with any internal rule, guideline, protocol, or other similar criteria that was relied upon in making the adverse determination or a statement that such rule, guideline, protocol, or other similar criteria of the Plan does not exist; (vi) provide the Claimant with an explanation of any scientific or clinical judgment for the determination if benefit determination is based on a medical necessity or experimental treatment or similar exclusion or limit or a statement that the benefit is based on such an exclusion or limit and such explanation will be provided free of charge; and (vii) provide the Claimant with the following statement: “You and your plan may have other voluntary alternative dispute resolution options, such as mediation. One way to find out what may be available is to contact your local
U.S. Department of Labor Office and your State insurance regulatory agency.” Any civil action under (iv) must be filed no later than one year after the date on the Plan Administrator’s notice.

The notice shall also provide the Claimant with a discussion of the decision, including an explanation of the basis for disagreeing with or not following, (i) the views presented by the Claimant to the Plan of health care professionals treating the Claimant and vocational professionals who evaluated the Claimant; (ii) the views of medical or vocational experts whose advice was obtained on behalf of the Plan in connection with a Claimant's adverse benefit determination, without regard to whether the advice was relied upon in making the benefit determination; and (iii) a disability determination regarding the Claimant presented by the Claimant to the Plan made by the Social Security Administration.

The notice shall be provided in a culturally and linguistically appropriate manner. Executed by Principal Life Insurance Company on , 2018

INTERIM AMENDMENT TO COMPLY WITH THE
FINAL REGULATIONS UNDER CODE SECTIONS 401(k) AND 401(m)

This amendment of the Plan is adopted to reflect certain provisions of the final regulations for  the suspension or reduction of safe harbor contributions under Code Sections 401(k) and 401(m). This amendment is to be construed in accordance with such law and guidance issued thereunder.

This amendment shall supersede the provisions of the Plan to the extent those provisions are inconsistent with the provisions of this amendment. This amendment shall continue to apply to the Plan, including the Plan as later amended, until such provisions are integrated into the Plan or the provisions of  this  amendment are specifically amended.

Plan Name Independent Bank 401(k) Profit Sharing Plan      

The Plan named above gives the Employer the right to amend the provisions of the Plan. According to that right, the Plan is amended as follows:

REVOCATION OF SAFE HARBOR CONTRIBUTIONS.

This amendment shall be effective as specified below, in accordance with the November 15, 2013, final regulations under Code Sections 401(k) and 401(m).

The 401(k) SAFE HARBOR PROVISIONS SECTION of Article III is amended by striking subparagraph (e) and substituting the following:

		
	(e)
	Revocation of 401(k) Safe Harbor Election .

The Employer may amend the Plan to revoke the 401(k) safe harbor election and the corresponding Qualified Matching Contributions or Qualified Nonelective Contributions during any Plan Year, if the following conditions are met:

(1)    The elimination of the Qualified Nonelective Contributions during a Plan Year is permitted for amendments adopted after May 18, 2009, and the elimination of the Qualified Matching Contributions is permitted for Plan Years beginning on or after January 1, 2015, if the Employer either

(i)    is operating at an economic loss as described in Code Section 412(c)(2)(A) for the Plan Year, or

(ii)    includes in the notice described in (b)(2) above a statement that the Plan may be amended during the Plan Year to revoke the Qualified Matching Contributions or Qualified Nonelective Contributions and that the revocation will not apply until at least 30 days after  all Active Participants are provided notice of the revocation.

(2)    All Active Participants shall be provided a supplemental notice that explains the consequences of the amendment, informs them of the effective date of the elimination of the Qualified Matching Contributions or Qualified Nonelective Contributions, and explains the procedures to change their Elective Deferral Agreement.

(3)    The effective date of the revocation cannot be earlier than the later of (i) 30 days after the  Active Participants are given such notice, and (ii) the date the amendment is adopted.

(4)    Active Participants are given a reasonable opportunity (including a reasonable period after receipt of the supplemental notice) to change their Elective Deferral Agreement prior to the revocation of the 401(k) safe harbor election.

If the 401(k) safe harbor election is revoked for the Plan Year, the Employer shall perform the ADP Test and ACP Test, if applicable, for the entire Plan Year using the current year testing method described in the EXCESS AMOUNTS SECTION of this article, and satisfy the Top-heavy Plan requirements of Article XI.

The Employer shall make the Qualified Matching Contributions, if applicable, with respect  to  Elective Deferral Contributions and Compensation for the portion of the Plan Year prior to the effective date of the revocation.  The Employer shall make the Qualified  Nonelective  Contributions, if applicable, with respect to Compensation paid for the portion of the Plan Year through  the effective date of the revocation. The annual compensation limit applied to Compensation for purposes of the Qualified Matching Contributions and Qualified Nonelective Contributions shall be adjusted for the short determination period as described in the definition of Compensation in the DEFINITIONS SECTION of Article I.

This amendment is made an integral part of the aforesaid Plan and is controlling over the terms of said Plan with respect to the particular items addressed expressly herein. All other provisions of the Plan remain unchanged and controlling.

Unless otherwise stated on any page of this amendment, eligibility for benefits and the amount of any benefits payable to or on behalf of an individual who is an Inactive Participant on the effective date(s) stated above, shall be determined according to the provisions of the aforesaid Plan as in effect on the day before  he became an Inactive Participant.

Signing this amendment, the Employer, as plan sponsor, has made the decision to adopt this plan amendment. The Employer is acting in reliance on its own discretion and on the legal and tax advice of its own advisors, and not that of any member of the Principal Financial Group or any representative of a member company of the Principal Financial Group.

Signed this     day of     ,     . By
