You can apply for an EIN from the IRS online, by fax, or by
mail depending on how soon you need to use the EIN. For
more information, see Section 3: Electronic Filing Requirement
under the General Instructions to Form 5500 and How to File –
Electronic Filing Requirement under the General Instructions to
Form 5500-SF. The EBSA does not issue EINs.
Note. (1) For split-funded plans, the costs and contributions
reported on Schedule MB must include those relating to both
trust funds and insurance carriers. (2) For plans with funding
standard account amortization charges and credits, see the
instructions for lines 9c and 9h. (3) For terminating
multiemployer plans, Code section 412(e)(4) and ERISA
section 301(c) provide that minimum funding standards apply
until the last day of the plan year in which the plan terminates
within the meaning of section 4041A(a)(2) of ERISA.
Accordingly, the Schedule MB is not required to be filed for any
later plan year.

20187 Instructions for Schedule MB
(Form 5500)
Multiemployer Defined Benefit Plan and
Certain Money Purchase Plan Actuarial
Information
General Instructions
Who Must File
As the first step, the plan administrator of any multiemployer
defined benefit plan that is subject to the minimum funding
standards (see Code sections 412 and 431 and Part 3 of Title I
of ERISA) must obtain a completed Schedule MB (Form 5500)
that is prepared and signed by the plan’s enrolled actuary as
discussed below in the Statement by Enrolled Actuary section.
The plan administrator must retain with the plan records the
Schedule MB that is prepared and signed by the plan’s actuary.
Next, the plan administrator of a multiemployer defined
benefit plan must ensure that the information from the
actuary’s Schedule MB is entered electronically into the annual
return/report being submitted. When entering the information,
whether using EFAST2-approved software or EFAST2’s webbased filing system, all the fields required for the type of plan
must be completed (see instructions for fields that need to be
completed).
Further, the plan administrator of a multiemployer defined
benefit plan must attach to the Form 5500 an electronic
reproduction of the Schedule MB prepared and signed by the
plan’s enrolled actuary. This electronic reproduction must be
labeled “MB Actuary Signature” and must be included as a
Portable Document Format (PDF) attachment or any
alternative electronic attachment allowable under EFAST2.
If a money purchase defined contribution plan (including a
target benefit plan) has received a waiver of the minimum
funding standard, and the waiver is currently being amortized,
lines 3, 9, and 10 of Schedule MB must be completed but it
need not be signed by an enrolled actuary. In such a case, the
Form 5500 or the Form 5500-SF that is submitted under
EFAST2 must include the Schedule MB with lines 3, 9, and 10
completed, but is not required to include a PDF attachment of a
signed Schedule MB.
Note. Schedule MB does not have to be filed with the Form
5500-EZ, but, if required, it must be retained (in accordance
with the instructions for Form 5500-EZ under the What to File
section). Similarly, if a plan is a one-participant plan that meets
the requirements for filing a Form 5500-EZ, but a Form 5500SF is instead filed for the plan, the Schedule MB, if required,
does not have to be filed with the Form 5500-SF, but it must be
retained (in accordance with the instructions for the Form
5500-SF under Schedule MB in the Specific Instructions Only
for “One-Participant Plans” section). Also, the funding standard
account for the plan must continue to be maintained, even if
the Schedule MB is not filed.
Check the Schedule MB box on the Form 5500 (Part II, line
10a(2)) if a Schedule MB is attached to the Form 5500.
Lines A through E must be completed for ALL plans. If the
Schedule MB is attached to a Form 5500 or Form 5500-SF,
lines A, B, C, and D should include the same information as
reported in Part II of the Form 5500 or Form 5500-SF. You
may abbreviate the plan name.
Do not use a social security number in line D in lieu of an
EIN. The Schedule MB and its attachments are open to public
inspection if filed with a Form 5500 or Form 5500-SF, and the
contents are public information and are subject to publication
Instructions for Schedule MB (Form 5500)

Statement by Enrolled Actuary
An enrolled actuary must sign Schedule MB unless, as
described above, the plan is a money purchase defined
contribution plan that has received a waiver of the minimum
funding standard. The signature of the enrolled actuary may be
qualified to state that it is subject to attached qualifications.
See Treasury Regulations section 301.6059-1(d) for permitted
qualifications. Except as otherwise provided in these
instructions, a stamped or machine produced signature is not
acceptable. If the actuary has not fully reflected any final or
temporary regulation, revenue ruling, or notice promulgated
under the statute in completing the Schedule MB, check the
box on the last line of page 1. If this box is checked, indicate
on an attachment whether an accumulated funding deficiency
or a contribution that is not wholly deductible would result if the
actuary had fully reflected such regulation, revenue ruling, or
notice, and label this attachment “Schedule MB – Statement
by Enrolled Actuary.” In addition, the actuary may offer any
other comments related to the information contained in
Schedule MB.
The actuary must provide the completed and signed
Schedule MB to the plan administrator to be retained with the
plan records and included (in accordance with these
instructions) with the Form 5500 that is submitted under
EFAST2. The plan’s actuary is permitted to sign the Schedule
MB on page one using the actuary’s signature or by inserting
the actuary’s typed name in the signature line followed by the
actuary’s handwritten initials. The actuary’s most recent
enrollment number must be entered on the Schedule MB that
is prepared and signed by the plan’s actuary.

Attachments
All attachments to the Schedule MB must be properly
identified, and must include the name of the plan, the plan
sponsor’s EIN, and the plan number. Put “Schedule MB” and
the line number to which the attachment relates at the top of
each attachment. Do not include attachments that contain a
visible social security number. The Schedule MB and its
attachments are open to public inspection, and the contents
are public information and are subject to publication on the
Internet. Because of privacy concerns, the inclusion of a visible
social security number or any portion thereof on an attachment
may result in the rejection of the filing.

Specific Instructions

Each other actuarial assumption used in calculating the
current liability must be the same assumption used for
calculating other costs for the funding standard account. See
Notice 90-11, 1990-1 C.B. 319. The actuary must take into
account rates of early retirement and the plan’s early
retirement and turnover provisions as they relate to benefits,
where these would significantly affect the results.
Regardless of the valuation date, current liability is computed
taking into account only credited service through the end of
the prior plan year. No salary scale projections should be
used in these computations. Do not include the expected
increase in current liability due to benefits accruing during
the plan year reported on line 1d(2)(b) in these
computations.
Line 1d(2)(b). Expected Increase in Current Liability.
Enter the amount by which the current liability is expected to
increase due to benefits accruing during the plan year on
account of credited service and/or salary changes for the
current year. One year’s salary scale may be reflected.
Line 1d(2)(c). Expected Release From Current Liability
for the Plan Year. Enter the expected release from current
liability on account of disbursements (including single-sum
distributions) from the plan expected to be paid after the
valuation date but prior to the end of the plan year (see also
Q&A-7 of Rev. Rul. 96-21, 1996-1 C.B. 64).
Line 1d(3). Expected Plan Disbursements. Enter the
amount of plan disbursements expected to be paid for the
plan year.
Line 2. All entries must be reported as of the beginning of
the 20187 plan year. Lines 2a and 2b should include all
assets and liabilities under the plan except for assets and
liabilities attributable to: (1) rollover amounts or other
amounts in individual accounts that are not available to
provide defined benefits, or (2) benefits for which an insurer
has made an irrevocable commitment as defined in 29 CFR
4001.2.
Line 2a. Current Value of Assets. Enter the current value
of net assets as of the first day of the plan year. Except for
plans with excluded assets as described above, this entry
should be the same as reported on the 20187 Schedule H
(Form 5500) (line 1l, column (a)) or Schedule I (Form 5500)
(line 1c, column (a)). Note that contributions designated for
the 20187 plan year are not included on those lines.
Line 2b. Current Liability (beginning of plan year). Enter
the current liability as of the first day of the plan year. Do not
include the expected increase in current liability due to
benefits accruing during the plan year. See the instructions
for line 1d(2)(a) for actuarial assumptions used in
determining current liability.
Column (1) – Enter the number of participants and
beneficiaries as of the beginning of the plan year. If the
current liability figures are derived from a valuation that
follows the first day of the plan year, the participant and
beneficiary count entries should be derived from the counts
used in that valuation in a manner consistent with the
derivation of the current liability reported in column (2).
Column (2) – Include the current liability attributable to
all benefits, with subtotals for vested and nonvested benefits
in the case of active participants.
Line 2c. This calculation is required under ERISA section
103(d)(11). Do not complete if line 2a divided by line 2b(4),
column (2), is 70% or greater.
Line 3. Contributions Made to Plan. Show all employer
and employee contributions for the plan year. Include
employer contributions made not later than 2½ months (or

Line 1. All entries must be reported as of the valuation date.
Line 1a. Actuarial Valuation Date. The valuation for a plan
year may be as of any date in the plan year, including the first
or last day of the plan year. Valuations must be performed
within the period specified by Code section 431(c)(7) and
ERISA section 304(c)(7).
Line 1b(1). Current Value of Assets. Enter the current value
of assets as of the valuation date. The current value is the
same as the fair market value. Do not adjust for items such as
the existing credit balance or the outstanding balances of
certain amortization bases. Contributions designated for 20187
should not be included in this amount. Note that this entry may
be different from the entry in line 2a. Such a difference may
result, for example, if the valuation date is not the first day of
the plan year, or if insurance contracts are excluded from
assets reported on line 1b(1) but not on line 2a.
Rollover amounts or other assets held in individual
accounts that are not available to provide defined benefits
under the plan should not be included on line 1b(1), regardless
of whether they are reported on the 20187 Schedule H (Form
5500) (line 1I, column (a)) or Schedule I (Form 5500) (line 1c,
column (a)). Additionally, asset and liability amounts must be
determined in a consistent manner. Therefore, if the value of
any insurance contracts have been excluded from the amount
reported on line 1b(1), liabilities satisfied by such contracts
should also be excluded from the liability values reported on
lines 1c(1), 1c(2), and 1d(2) of the Schedule MB.
Line 1b(2). Actuarial Value of Assets. Enter the value of
assets determined in accordance with Code section 431(c)(2)
and ERISA section 304(c)(2). Do not adjust for items such as
the existing credit balance or the outstanding balances of
certain amortization bases, and do not include contributions
designated for 20187 in this amount.
Line 1c(1). Accrued Liability for Immediate Gain Methods.
Complete this line only if you use an immediate gain method
(see Rev. Rul. 81-213, 1981-2 C.B. 101, for a definition of
immediate gain method).
Lines 1c(2)(a), (b), and (c). Information for Plans Using
Spread Gain Methods. Complete these lines only if you use a
spread gain method (see Rev. Rul. 81-213 for a definition of
spread gain method).
Line 1c(2)(a). Unfunded Liability for Methods with Bases.
Complete this line only if you use the frozen initial liability or
attained age normal cost method.
Lines 1c(2)(b) and (c). Entry Age Normal Accrued Liability
and Normal Cost. For spread gain methods, these
calculations are used for purposes of the full funding limitation
(see Rev. Rul. 81-13, 1981-1 C.B. 229).
Line 1d(1). Amount Excluded from Current Liability.
Leave line 1(d)(1) blank.
Line 1d(2)(a). Current Liability. All multiemployer plans,
regardless of the number of participants, must provide the
information indicated in accordance with these instructions.
The interest rate used to compute the current liability must be
in accordance with guidelines issued by the IRS and, pursuant
to the Pension Protection Act of 2006 (PPA), must not be more
than 5 percent above and must not be more than 10 percent
below the weighted average of the rates of interest, as set forth
by the Treasury Department, on 30-year Treasury securities
during the 4-year period ending on the last day before the
beginning of the 20187 plan year.
The current liability must be computed using the mortality
tables referenced in section 1.431(c)(6)-1 of the Treasury
Regulations.

Add the amounts in both columns (b) and (c) and enter
both results on the total line. All contributions must be
credited toward a particular plan year.
If any of the contributions reported in line 3 include
amounts owed for withdrawal liability, attach a list separately
identifying, for each reported contribution, the aggregate
amount of withdrawal liability payments included in such
contributionand the dates such amounts were contributed.
Label this attachment “Schedule MB, Line 3 – Withdrawal
Liability Amounts.”
Line 4. Information on Plan Status. All multiemployer plans
regardless of the number of participants must provide the
information indicated in accordance with these instructions.
Line 4a. All plans enter the funded percentage for monitoring
the plan’s status. This is line 1b(2) divided by line 1c(3).
Line 4b. Enter the code for the status of the multiemployer
plan for the plan year, as certified by the plan actuary, (or as
elected by the plan sponsor in accordance with Code section
432(b)(4)(A) and ERISA section 305(b)(4)(A)) using one of
the following codes:

the plan is certified as being in critical status. Plans that are
certified as being in critical and declining status should
determine whether benefits have been reduced, including all
benefits that were adjusted (only adjustable benefits that would
otherwise be protected under Code section 411(d)(6) and
ERISA section 204(g) are taken into account), any benefits that
have been suspended under Code section 432(e)(9), and any
benefit reductions due to a partition under ERISA section 4233.
For a plan that has benefits suspended under Code section
432(e)(9) and/or partitioned under ERISA section 4233, attach
a full description of the transaction and label the attachment
“Schedule MB, Lines 4d and 4e – Description of Benefit
Reductions Due to Suspension or Partition”. In addition,
only benefit reductions that are first reflected in line 1c(3) for
the current year's Schedule MB should be reported, and this
amount should not include any amounts previously reported on
any prior year's Schedule MB.
Line 4f. If Code C (Critical Status) or Code D (Critical and
Declining Status) was entered on line 4b you must complete
line 4f as follows:. If the rehabilitation plan projects emergence
from critical status or critical and declining status, enter the
plan year in which the plan is projected to emerge. If the
rehabilitation plan is based on forestalling possible insolvency,
check the box provided and enter the plan year in which the
insolvency is expected. Attach supporting documentation for
these projections, showing year-by-year cash flow projections
for the period ending with whichever is applicable: the year the
plan is projected to emerge from Critical or Critical and
Declining Status or the year the plan is projected to become
insolvent and a summary of the assumptions underlying these
projections. Label this attachment “Schedule MB, line 4f –
Illustration Supporting year of Emergence (or Insolvency)”

Plan Status
Endangered Status
Seriously Endangered Status
Critical Status
Critical and Declining Status
Not in Endangered or Critical Status

• If, under the terms of the most recently adopted
rehabilitation plan, the plan is projected to emerge from
critical status within 30 years, enter the plan year in which
the plan is projected to emerge from critical status.

If the plan is certified to be in endangered status, seriously
endangered status, critical status, or critical and declining
status, attach a copy of the actuarial certification of such status
to this Schedule MB. Also attach an illustration showing the
details (including year-by-year cash flow projections
demonstrating the solvency of the plan over the relevant period
if the plan is certified as being in critical and declining status)
providing support for the actuarial certification of status and
label the illustration “Schedule MB, line 4b – Illustration
Supporting Actuarial Certification of Status.” For example,
if a plan is certified as being in critical status based on Code
section 432(b)(2)(B), show the funded percentage (if
applicable) and the projection of the funding standard account
for the year in which the accumulated funding deficiency
occurs. All supporting documentation should include
descriptions of the assumptions used.
Line 4c. If, in the plan year in which the Schedule MB is filed, a
certification was required to be made under Code section
432(b)(3)(A)(ii) and ERISA section 305(b)(3)(A)(ii) with respect
to scheduled progress during the plan year for which the
Schedule MB is filed, check “Yes” or “No” to reflect the
certification. Attach documentation comparing the current
status of the plan to the scheduled progress under the
applicable funding improvement or rehabilitation plan to this
Schedule MB. Label the documentation “Schedule MB, line
4c – Documentation Regarding Progress Under Funding
Improvement or Rehabilitation Plan.”
Lines 4d and 4e. If Code C (Critical Status) or Code D (Critical
and Declining Status) was entered on line 4b, an entry on line
4d is required. For purposes of lines 4d and 4e, in determining
whether benefits have been reduced, only adjustable benefits
that would otherwise be protected under Code section
411(d)(6) and ERISA section 204(g) are taken into account if

• If, under the terms of the most recently adopted
rehabilitation plan, the plan is projected to become
insolvent within 30 years, check the box provided, enter the
plan year in which the insolvency is expected. In addition,
attach an illustration showing year by-year cash flow
projections for the period ending with the year the plan is
projected to become insolvent (or the 20th year after the
valuation year if earlier) and a summary of the assumptions
underlying the projections. Label this attachment
“Schedule MB, line 4f – Cash Flow Projections”.
• If, under the terms of the most recently adopted
rehabilitation plan, the plan is neither projected to emerge
from critical status nor become insolvent within 30 years,
check the box provided, enter the year of projected
emergence or insolvency in the space for plan year (or
“9999” if such year has not been determined). In addition,
attach an illustration showing year by-year cash flow
projections ending with the 20th year after the valuation
year and a summary of the assumptions underlying the
projections. Label this attachment “Schedule MB, line 4f –
Cash Flow Projections”.
Line 5. Actuarial Cost Method. Enter the primary method
used. If the plan uses one actuarial cost method in one year as
the basis of establishing an accrued liability for use under the
frozen initial liability method in subsequent years, answer as if
the frozen initial liability method was used in all years. The
projected unit credit method is included in the “Accrued benefit
(unit credit)” category of line 5c. If a method other than a
method listed on lines 5a through 5g is used, check the box for
line 5i and specify the method. For example, if a modified
-3-

individual level premium method for which actuarial gains and
losses are spread as a part of future normal cost is used,
check the box for 5i and describe the cost method.
Check the appropriate box for the underlying actuarial
cost method used as the basis for this plan year’s funding
standard account computation. If box 5h is checked, enter
the period of use of the shortfall method in line 5j. For this
purpose, enter the calendar year (YY) which includes the
first day of the plan year in which the shortfall method was
first used.
Changes in funding methods include changes in actuarial
cost method, changes in asset valuation method, and changes
in the valuation date of plan costs and liabilities or of plan
assets. Changes in the funding method of a plan include not
only changes to the overall funding method used by the plan,
but also changes to each specific method of computation used
in applying the overall method. Generally, these changes
require IRS approval. If the change was made pursuant to
Rev. Proc. 2000-40, 2000-2 C.B. 357, or pursuant to other
automatic approval (such as the Preservation of Access to
Care for Medicare Beneficiaries and Pension Relief Act of
2010 (PRA 2010), Pub. L. No. 111-192), check “Yes” for line
5l. If approval was granted for this plan by either an individual
ruling letter or a class ruling letter, enter the date of the
applicable ruling letter in line 5m. Note that the plan sponsor's
agreement to certain changes in funding methods should be
reported on line 8 of Schedule R (Form 5500).
Shortfall Method: Only certain plans may elect the shortfall
funding method (see Treasury Regulations section
1.412(c)(1)-2). Advance approval from the IRS for the
election of the shortfall method of funding is NOT required if
it is first adopted for the first plan year to which Code section
412 applies. In addition, pursuant to PPA section 201(b), a
plan does NOT need advance approval from the IRS to
adopt or cease using the shortfall method if the plan (1) has
not adopted or ceased using the shortfall method during the
5-year period ending on the day before the date the plan is
to use the method, and (2) is not operating under an
amortization period extension and did not operate under
such an extension during such 5-year period. In such a case,
check “Yes” for line 5l. If a plan utilizes this automatic
approval to apply the shortfall method, the benefit increase
limitations of Code section 412(c)(7) apply.
If a plan is not eligible for automatic approval as set forth
in the preceding paragraph, advance approval from the IRS
is required if the shortfall funding method is adopted at a
later time, if a specific computation method is changed, or if
the shortfall method is discontinued. In such a case there is
no automatic limitation on benefit increases.
Line 6. Actuarial Assumptions. If gender-based
assumptions are used in developing plan costs, enter those
rates where appropriate in line 6. Note that requests for
gender-based cost information do not suggest that genderbased benefits are legal. If unisex tables are used, enter the
values in both “Male” and “Female” lines. Check “N/A” for
line 6b if the question is not applicable.
Attach a statement of actuarial assumptions (if not fully
described by line 6) and actuarial methods used to calculate
the figures shown in lines 1 and 9 (if not fully described by
line 5), and label the statement “Schedule MB, line 6 –
Statement of Actuarial Assumptions/Methods.” The
statement must describe all actuarial assumptions used to
determine the liabilities. For example, the statement for nontraditional plans (e.g., cash balance plans) must include the
assumptions used to convert balances to annuities.

Also attach a summary of the principal eligibility and
benefit provisions on which the valuation was based,
including the status of the plan (e.g., eligibility frozen,
service/pay frozen, benefits frozen), optional forms of
benefits, special plan provisions, including those that apply
only to a subgroup of employees (e.g., those with imputed
service), supplemental benefits, an identification of benefits
not included in the valuation (e.g., shutdown benefits), a
description of any significant events that occurred during the
year, a summary of any changes in principal eligibility or
benefit provisions since the last valuation, a description (or
reasonably representative sample) of plan early retirement
factors, and any change in actuarial assumptions or cost
methods and justifications for any such change (see section
103(d) of ERISA). Label the summary “Schedule MB, line 6
– Summary of Plan Provisions.”
Also, include any other information needed to disclose the
actuarial position of the plan fully and fairly, including the
weighted average retirement age.
Line 6a. Current Liability Interest Rate. Enter the interest
rate used to determine current liability. The interest rate used
must be in accordance with the guidelines issued by the IRS
and, pursuant to PPA, must not be more than 5 percent
above and must not be more than 10 percent below the
weighted average of the rates of interest, as set forth by the
Treasury Department, on 30-year Treasury securities during
the 4-year period ending on the last day before the
beginning of the 20187 plan year. Enter the rate to the
nearest .01 percent.
Line 6b. Check “Yes,” if the rates in the contract were used
(e.g., purchase rates at retirement).
Line 6c. Mortality Table. The mortality table published in
section 1.431(c)(6)-1 of the Treasury Regulations must be used
in the calculation of current liability for non-disabled lives. Enter
the mortality table code for non-disabled lives used for valuation
purposes as follows:

Instructions for Schedule MB (Form 5500)

include the 1983 G.A.M. male-only table used for males,
where the 1983 G.A.M. male-only table with a 6-year
setback is used for females. Code A includes mortality tables
other than those listed in Codes 1 through 9, including any
unisex version of the 1983 G.A.M. table.
Where an indicated table consists of separate tables for
males and females, add F to the female table (e.g., 1F).
When a projection is used with a table, follow the code with
“P” and the year of projection (omit the year if the projection
is unrelated to a single calendar year). The identity of the
projection scale should be omitted from line 6c, but a
description of projection techniques, including the projection
scales used, should be included in the Schedule MB, line 6
– Statement of Actuarial Assumptions/Methods. When
an age setback or set forward is used, indicate with “ – ” or
“+” and the number of years. For example, if for females the
1951 Group Annuity Table with Projection C to 1971 is used
with a 5-year setback, enter “1P71-5.” If the table is not one
of those listed, enter “A” with no further notation. If the
valuation assumes a maturity value to provide the postretirement income without separately identifying the
mortality, interest and expense elements, enter on line 6c,
under “Post-retirement,” the value of $1.00 of monthly
pension beginning at the plan’s weighted average retirement
age, assuming the normal form of annuity for an unmarried
person. In such a case, leave lines 6d and 6e blank.
Line 6d. Valuation Liability Interest Rate. Enter the
assumption as to the expected interest rate (investment
return) used to determine all the calculated values except for
current liability. If the assumed rate varies with the year,
enter the weighted average of the assumed rate for 20 years
following the valuation date. Enter rates to the nearest .01
percent.
Line 6e. Expense Loading. If there is no expense loading,
check the "N/A" boxes under "Pre-retirement" and "Postretirement”. For instance, there would be no expense loading
attributable to investments if the rate of investment return on
assets is adjusted to take investment expenses into account.
If there is a single expense loading not separately identified
as pre-retirement or post-retirement, enter it under “Preretirement” and check the “N/A“ box under “PostRetirement.” Where expenses are assumed other than as a
percentage of plan costs or liabilities, enter the assumed
pre-retirement expense as a percentage of the plan’s normal
cost, and enter the post-retirement expense as a percentage
of plan liabilities. If the normal cost of the plan is zero, enter
the assumed pre-retirement expense as a percentage of the
sum of lines 9c(1), 9c(2), and 9c(3), minus line 9h. Enter
rates to the nearest .1 percent.
Line 6f. Salary Scale. If a uniform level annual rate of salary
increase is used, enter that annual rate. Otherwise, enter the
level annual rate of salary increase that is equivalent to the
rate(s) of salary increase used. Enter the annual rate as a
percentage to the nearest .01 percent, used for a participant
from age 25 to assumed retirement age. If the plan’s benefit
formula is not related to compensation, check the “N/A” box.
Line 6g. Estimated Investment Return – Actuarial Value.
Enter the estimated rate of return on the actuarial value of
plan assets for the 1-year period ending on the valuation
date. For this purpose, the rate of return is determined by
using the formula 2I/(A + B – I), where I is the dollar amount
of the investment return under the asset valuation method
used for the plan, A is the actuarial value of the assets one
year ago, and B is the actuarial value of the assets on the
current valuation date. Enter rates to the nearest .1 percent.

Instructions for Schedule MB (Form 5500)

If entering a negative number, enter a minus sign (“ – ”) to
the left of the number.
Note. Use the above formula even if the actuary feels that the
result of using the formula does not represent the true
estimated rate of return on the actuarial value of plan assets for
the 1-year period ending on the valuation date. The actuary
may attach a statement showing both the actuary’s estimate of
the rate of return and the actuary’s calculations of that rate,
and label the statement “Schedule MB, line 6g – Estimated
Rate of Investment Return (Actuarial Value).”
Line 6h. Estimated Investment Return – Current (Market)
Value. Enter the estimated rate of return on the current value
of plan assets for the 1-year period ending on the valuation
date. (The current value is the same as the fair market value —
see line 1b(1) instructions.) For this purpose, the rate of return
is determined by using the formula 2I/(A + B – I), where I is
the dollar amount of the investment return, A is the current
value of the assets one year ago, and B is the current value of
the assets on the current valuation date. Enter rates to the
nearest .1 percent. If entering a negative number, enter a
minus sign (“ – ”) to the left of the number.
Note. Use the above formula even if the actuary feels that the
result of using the formula does not represent the true
estimated rate of return on the current value of plan assets for
the 1-year period ending on the valuation date. The actuary
may attach a statement showing both the actuary’s estimate of
the rate of return and the actuary’s calculations of that rate,
and label the statement “Schedule MB, line 6h – Estimated
Rate of Investment Return (Current Value).”
Line 7. New Amortization Bases Established. List all new
amortization bases established in the current plan year (before
the combining of bases, if bases were combined). Use the
following table to indicate the type of base established, and
enter the appropriate code under “Type of base.” List
amortization bases and charges and/or credits as of the
valuation date. Bases that are considered fully amortized
because there is a credit for the plan year on line 9j(3) should
be listed. If entering a negative number, enter a minus sign (“–
”) to the left of the number.

Line 8a and 8d. Funding Waivers or Extensions. If a
funding waiver or extension request is approved after the
Schedule MB is filed, an amended Schedule MB must be
filed with Form 5500 to report the waiver or extension
approval (also see instructions for line 9k(1)).
Line 8b(1). Schedule of Projection of Expected Benefit
Payments. Check “Yes” only if this is a multiemployer plan
covered by Title IV of ERISA that has 500 or more total
participants as of the valuation date.
If line 8b(1) is “Yes,” in an attachment, provide a
projection of benefits expected to be paid for the entire plan

(not to include expected expenses) in each of the next ten
years starting with the current plan year of this filing
assuming (1) no additional accruals, (2) experience (e.g.,
termination, mortality, and retirement) are in line with
valuation assumptions, and (3) no new entrants are covered
by the plan. Use the format shown below and label the
schedule “Schedule MB, line 8b(1) – Schedule of
Projection of Expected Benefit Payments”.

each grouping, enter the average compensation of the active
participants in that group. For this purpose, compensation is
the compensation taken into account for each participant
under the plan’s benefit formula, limited to the amount
defined under section 401(a)(17) of the Code. Do not enter
the average compensation in any grouping that contains
fewer than 20 participants.
Cash balance plans (or any plans using characteristic
code 1C on line 8a of Form 5500) reporting 1,000 or more
active participants on line 2b(3)(c), column (1), must also
provide average cash balance account data, regardless of
whether all active participants have cash balance accounts.
For each age/service bin, enter the average cash balance
account of the active participants in that bin. Do not enter the
average cash balance account in any age/service bin that
contains fewer than 20 active participants.
General Rule. In general, data to be shown in each
age/service bin includes:
1. the number of active participants in the age/service
bin,
2. the average compensation of the active participants in
the age/service bin, and
3. the average cash balance account of the active
participants in the age/service bin, using $0 for anyone who
has no cash balance account-based benefit.
If the accrued benefit is the greater of a cash balance benefit
or some other benefit, average in only the cash balance
account. If the accrued benefit is the sum of a cash balance
account benefit and some other benefit, average in only the

and the average cash balance account, do not enter an
amount for age/service bins with fewer than 20 active
participants.
In lieu of the above, two alternatives are provided for
showing compensation and cash balance accounts. Each
alternative provides for two age/service scatters (one
showing compensation and one showing cash balance
accounts) as follows:
Alternative A:
• Scatter 1 - Provide participant count and average
compensation for all active participants, whether or not
participants have account-based benefits.
• Scatter 2 - Provide participant count and average cash
balance account for all active participants, whether or not
participants have account-based benefits.
Alternative B:

If line 8b(2) is “Yes,” attach a schedule of the active plan
participant data used in the valuation for this plan year. Use
the format shown above and label the schedule “Schedule
MB, line 8b(2) – Schedule of Active Participant Data.”
Expand this schedule by adding columns after the “5 to
9” column and before the “40 & up” column for active
participants with total years of credited service in the
following ranges: 10 to14; 15 to 19; 20 to 24; 25 to 29; 30 to
34; and 35 to 39. For each column, enter the number of
active participants with the specified number of years of
credited service divided according to age group. For
participants with partial years of credited service, round the
total number of years of credited service to the next lower
whole number. Years of credited service are the years
credited under the plan’s benefit formula.
Plans reporting 1,000 or more active participants on line
2b(3)(c), column (1), and using compensation to determine
benefits must also provide average compensation data. For

Instructions for Schedule MB (Form 5500)

• Scatter 1 - Provide participant count and average
compensation for all active participants, whether or not
participants have account-based benefits (i.e., identical to
Scatter 1 in Alternative A).
• Scatter 2 - Provide participant count and average cash
balance account for only those active participants with
account based benefits. If the number of participants with
account-based benefits in a bin is fewer than 20, the average
account should not be shown even if there are more than 20
active participants in this bin on Scatter 1.
In general, information should be determined as of the
valuation date. Average cash balance accounts may be
determined as of either:
1. the valuation date or
2. the day immediately preceding the valuation date.
Average cash balance accounts that are offset by
amounts from another plan may be reported either as
amounts prior to taking into account the offset or as amounts
after taking into account the offset. Do not report the offset
amount. For this or any other unusual or unique situation,
the attachment should include an explanation of what is
being provided.
Line 9. Shortfall Method. Under the shortfall method of
funding, the normal cost in the funding standard account is
the charge per unit of production (or per unit of service)
multiplied by the actual number of units of production (or
units of service) that occurred during the plan year. Each
amortization installment in the funding standard account is
similarly calculated.
Lines 9c and 9h. Amortization Charges and Credits. If
there are any amortization charges or credits, attach a
maintenance schedule of funding standard account bases
and label the schedule “Schedule MB, lines 9c and 9h –
Schedule of Funding Standard Account Bases.” The
attachment should clearly indicate the type of base (i.e.,
original unfunded liability, amendments, actuarial losses,
etc.), the outstanding balance of each base, the number of
years remaining in the amortization period, and the
amortization amount. If bases were combined in the current
year, the attachment should show information on bases both
prior to and after the combining of bases.
The outstanding balance and amortization charges and
credits must be calculated as of the valuation date for the
plan year.
Line 9c(3) should only include information related to the
amortization bases extended and amortized using the
interest rate under section 6621(b) of the Code.
Line 9d. Interest as Applicable. Interest as applicable
should be charged to the last day of the plan year.
Line 9f. Note that the credit balance or funding deficiency at
the end of “Year X” should be equal to the credit balance or
funding deficiency at the beginning of “Year X+1.” If such
credit balances or funding deficiencies are not equal, attach
an explanation and label the attachment “Schedule MB, line
9f – Explanation of Prior Year Credit Balance/Funding
Deficiency Discrepancy.” For example, if the difference is
because contributions for a prior year that were not
previously reported are received this plan year, attach a
listing of the amounts and dates of such contributions. As
another example, if the difference is due to the application of
funding relief under the Preservation of Access to Care for
Medicare Beneficiaries and Pension Relief Act of 2010 (PRA
2010), Pub. L. No. 111-192, the attachment should show
how the information on the Schedule MB filed for any
Instructions for Schedule MB (Form 5500)

previous plan year would have differed if it had reflected
application of the special funding relief in accordance with
published guidance (to the extent that the plan sponsor has
applied the special funding relief).
Line 9j(1). ERISA Full Funding Limitation. Instructions for
this line are reserved pending published guidance.
Line 9j(2). “RPA ’94” Override. Instructions for this line are
reserved pending published guidance.
Line 9j(3). Full Funding Credit. Enter the excess of (1) the
accumulated funding deficiency, disregarding the credit
balance and contributions for the current year, if any, over
(2) the greater of lines 9j(1) or 9j(2).
Line 9k(1). Waived Funding Deficiency Credit. Enter a
credit for a waived funding deficiency for the current plan
year (Code section 431(b)(3)(C)). If a waiver of a funding
deficiency is pending, report a funding deficiency. If the
waiver is granted after Form 5500 or Form 5500-SF is filed,
file an amended Form 5500 or Form 5500-SF, as applicable,
with an amended Schedule MB to report the funding waiver
(see Amended Return/Report in the instructions for Form
5500 or line B – Box for Amended Return/Report in the
instructions for Form 5500-SF, as applicable).
Line 9k(2). Other Credits. Enter a credit in the case of a
plan for which the accumulated funding deficiency is
determined under the funding standard account if such plan
year follows a plan year for which such deficiency was
determined under the alternative minimum funding standard.
Line 9o. Reconciliation Account. The reconciliation
account is made up of those components that upset the
balance equation of Treasury Regulations section
1.412(c)(3)-1(b). Valuation assets must not be adjusted by
the reconciliation account balance when computing the
required minimum funding.
Line 9o(1). This amount is equal to the prior year’s
accumulated reconciliation amount due to prior waived
funding deficiencies, increased with interest at the valuation
rate to the current valuation date.
Line 9o(2)(a). If an amortization extension is being
amortized at an interest rate that differs from the valuation
rate, enter the prior year’s “reconciliation amortization
extension outstanding balance,” increased with interest at
the valuation interest rate to the current valuation date, and
decreased by the year end amortization amount based on
the amortization interest rate from the prior plan year.
Line 9o(3). Enter the sum of lines 9o(1) and 9o(2)(b) (each
adjusted with interest at the valuation rate to the current
valuation date, if necessary).
Note. The net outstanding balance of amortization charges
and credits minus the prior year’s credit balance minus the
amount on line 9o(3) (each adjusted with interest at the
valuation rate, if necessary) must equal the unfunded
liability.
Line 10. Contribution Necessary to Avoid Deficiency.
Enter the amount from line 9n. If applicable, file IRS Form
5330, Return of Excise Taxes Related to Employee Benefit
Plans, with the IRS to pay the excise tax on the funding
deficiency. There is a penalty for not filing the Form 5330 on
time.
Line 11. In accordance with ERISA section 103(d)(3), attach
a justification for any change in actuarial assumptions for the
current plan year and label the attachment “Schedule MB,
line 11 – Justification for Change in Actuarial
Assumptions.”
