IMPORTANT

DISTRIBUTION

NOTICE

for

Shareholders

of

the

Nuveen

Dynamic

Municipal

Opportunity

Fund

(NDMO)

Semi-annual

Shareholder

Report

for

the

period

ending

April

30,

2023

The

Nuveen

Dynamic

Municipal

Opportunity

Fund

(NDMO)

seeks

to

offer

attractive

cash

flow

to

its

shareholders,

by

converting

the

expected

long-term

total

return

potential

of

the

Fund’s

portfolio

of

investments

into

regular

monthly

distributions.

Following

is

a

discussion

of

the

Managed

Distribution

Policy

the

Fund

uses

to

achieve

this.

The

Fund

pays

monthly

common

share

distributions

that

seek

to

convert

the

Fund’s

expected

long-term

total

return

potential

into

regular

cash

flow.

As

a

result,

the

Fund’s

regular

common

share

distributions

(presented

$0.0620

per

share)

may

be

derived

from

a

variety

of

sources,

including:

Net

investment

income

consisting

of

regular

interest

and

dividends

Realized

capital

gains

or,

Possibly,

returns

of

capital

representing

in

certain

cases

unrealized

capital

appreciation.

Such

distributions

are

sometimes

referred

to

as

"managed

distributions."

The

Fund

seeks

to

establish

a

distribution

rate

that

roughly

corresponds

to

the

Adviser's

projections

of

the

total

return

that

could

reasonably

be

expected

to

be

generated

by

the

Fund

over

an

extended

period

of

time.

The

Adviser

may

consider

many

factors

when

making

such

projections,

including,

but

not

limited

to,

long-term

historical

returns

for

the

asset

classes

in

which

the

Fund

invests.

As

portfolio

and

market

conditions

change,

the

distribution

amount

and

distribution

rate

on

the

Common

Shares

under

the

Fund's

Managed

Distribution

Policy

could

change.

When

it

pays

a

distribution,

the

Fund

provides

holders

of

its

Common

Shares

a

notice

of

the

estimated

sources

of

the

Fund's

distributions

(i.e.,

what

percentage

of

the

distributions

is

estimated

to

constitute

ordinary

income,

short-term

capital

gains,

long-term

capital

gains,

and/or

a

non-taxable

return

of

capital)

on

a

year-to-date

basis.

It

does

this

by

posting

the

notice

on

its

website

(www.nuveen.com/cef),

and

by

sending

it

in

written

form.

You

should

not

draw

any

conclusions

about

the

Fund's

investment

performance

from

the

amount

of

this

distribution

or

from

the

terms

of

the

Fund's

Managed

Distribution

Policy.

The

Fund's

actual

financial

performance

will

likely

vary

from

month-to-month

and

from

year-to-year,

and

there

may

be

extended

periods

when

the

distribution

rate

will

exceed

the

Fund's

actual

total

returns.

The

Managed

Distribution

Policy

provides

that

the

Board

may

amend

or

terminate

the

Policy

at

any

time

without

prior

notice

to

Fund

shareholders.

There

are

presently

no

reasonably

foreseeable

circumstances

that

might

cause

the

Fund

to

terminate

its

Managed

Distribution

Policy.

Chair’s

Letter

to

Shareholders

Dear

Shareholders,

The

significant

measures

taken

by

the

U.S.

Federal

Reserve

(Fed)

and

other

global

central

banks

over

the

past

year

to

contain

inflation

have

begun

to

take

effect.

From

March

2022

to

May

2023,

the

Fed

raised

the

target

fed

funds

rate

by

5.00%

to

a

range

of

5.00%

to

5.25%,

marking

the

fastest

interest

rate

hiking

cycle

in

its

history.

Across

most

of

the

world,

inflation

rates

have

fallen

from

their

post-pandemic

highs

but

currently

remain

well

above

the

levels

that

central

banks

consider

supportive

of

their

economies’

long-term

growth.

At

the

same

time,

the

U.S.

and

other

large

economies

have

remained

surprisingly

resilient,

even

as

financial

conditions

have

tightened.

Despite

contracting

in

the

first

half

of

2022,

U.S.

gross

domestic

product

grew

2.1%

in

the

year

overall

compared

to

2021

and

expanded

at

a

more

moderate

pace

of

1.3%

in

the

first

quarter

of

2023.

A

relatively

strong

jobs

market

has

helped

support

consumer

sentiment

and

spending

despite

historically

high

inflation.

Markets

are

concerned

that

these

conditions

could

keep

upward

pressure

on

prices

and

wages,

although

the

recent

collapse

of

three

regional

U.S.

banks

(Silicon

Valley

Bank,

Signature

Bank

and

First

Republic

Bank)

and

major

European

bank

Credit

Suisse

is

likely

to

add

further

downward

pressure

to

the

economy

as

the

banking

system

slows

lending

in

response.

Fed

officials

are

closely

monitoring

inflation

data

and

other

economic

measures

to

modify

their

rate

setting

activity

based

upon

these

factors

on

a

meeting-by-meeting

basis,

including

pausing

rate

adjustments

at

the

most

recent

meeting

in

June

2023

in

order

to

assess

the

effects

of

monetary

policy

so

far

on

the

economy.

While

uncertainty

has

increased

given

the

unpredictable

outcome

of

tighter

credit

conditions

on

the

economy,

the

Fed

remains

committed

to

acting

until

it

sees

sustainable

progress

toward

its

inflation

goals.

In

the

meantime,

markets

are

likely

to

continue

reacting

in

the

short

term

to

news

about

inflation

data,

economic

indicators

and

central

bank

policy.

The

debt

ceiling

debate

in

Congress

was

also

looming

over

the

markets

until

the

government

passed

an

increase

to

the

debt

limit

in

early

June

2023

and

averted

a

default

scenario.

We

encourage

investors

to

keep

a

long-term

perspective

amid

the

short-term

noise.

Your

financial

professional

can

help

you

review

how

well

your

portfolio

is

aligned

with

your

time

horizon,

risk

tolerance

and

investment

goals.  

On

behalf

of

the

other

members

of

the

Nuveen

Fund

Board,

we

look

forward

to

continuing

to

earn

your

trust

in

the

months

and

years

ahead.

Fund

Leverage

IMPACT

OF

THE

FUNDS’

LEVERAGE

STRATEGY

ON

PERFORMANCE

One

important

factor

impacting

the

returns

of

the

Funds’

common

shares

relative

to

their

comparative

benchmarks

was

the

Funds’

use

of

leverage

through

their

issuance

of

preferred

shares

and/or

investments

in

inverse

floating

rate

securities,

which

represent

leveraged

investments

in

underlying

bonds.

The

Funds

use

leverage

because

our

research

has

shown

that,

over

time,

leveraging

provides

opportunities

for

additional

income.

The

opportunity

arises

when

short-term

rates

that

a

Fund

pays

on

its

leveraging

instruments

are

lower

than

the

interest

the

Fund

earns

on

its

portfolio

of

long-term

bonds

that

it

has

bought

with

the

proceeds

of

that

leverage.

However,

use

of

leverage

can

expose

Fund

common

shares

to

additional

price

volatility.

When

a

Fund

uses

leverage,

the

Fund’s

common

shares

will

experience

a

greater

increase

in

their

net

asset

value

if

the

securities

acquired

through

the

use

of

leverage

increase

in

value,

but

will

also

experience

a

correspondingly

larger

decline

in

their

net

asset

value

if

the

securities

acquired

through

leverage

decline

in

value.

All

this

will

make

the

shares’

total

return

performance

more

variable

over

time.

In

addition,

common

share

income

in

levered

funds

will

typically

decrease

in

comparison

to

unlevered

funds

when

short-term

interest

rates

increase

and

increase

when

short-term

interest

rates

decrease.

In

recent

quarters,

fund

leverage

expenses

have

generally

tracked

the

overall

movement

of

short-term

interest

rates.

While

fund

leverage

expenses

are

higher

than

their

prior

year

lows,

leverage

nevertheless

continues

to

provide

the

opportunity

for

incremental

common

share

income,

particularly

over

longer-term

periods.

The

Funds’

use

of

leverage

significantly

contributed

to

relative

performance

during

the

reporting

period.

In

addition,

the

Funds’

use

of

leverage

was

accretive

to

overall

common

share

income.

As

of

April

30,

2023,

the

Funds’

percentages

of

leverage

are

COMMON

SHARE

DISTRIBUTION

INFORMATION

The

following

information

regarding

the

distributions

for

NVG,

NZF,

NMZ

and

NMCO

are

current

as

of

April

30,

2023.

Each

Fund’s

distribution

levels

may

vary

over

time

based

on

each

Fund’s

investment

activity

and

portfolio

investments

value

changes.

During

the

current

reporting

period,

each

Fund’s

distributions

to

common

shareholders

were

as

shown

in

the

accompanying

table.

NVG,

NZF,

NMZ

and

NMCO

seek

to

pay

regular

monthly

dividends

out

of

their

net

investment

income

at

a

rate

that

reflects

their

past

and

projected

net

income

performance.

To

permit

each

Fund

to

maintain

a

more

stable

monthly

dividend,

the

Fund

may

pay

dividends

at

a

rate

that

may

be

more

or

less

than

the

amount

of

net

income

actually

earned

by

the

Fund

during

the

period.

Distributions

to

common

shareholders

are

determined

on

a

tax

basis,

which

may

differ

from

amounts

recorded

in

the

accounting

records.

In

instances

where

the

monthly

dividend

exceeds

the

earned

net

investment

income,

the

Fund

would

report

a

negative

undistributed

net

ordinary

income.

Refer

to

Notes

to

Financial

Statements

for

additional

information

regarding

the

amounts

of

undistributed

net

income

and

undistributed

net

long-term

capital

gains

and

the

character

of

the

actual

distributions

paid

by

the

Fund

during

the

period.

All

monthly

dividends

paid

by

NVG,

NZF,

NMZ

and

NMCO

during

the

current

reporting

period

were

paid

from

net

investment

income.

If

a

portion

of

the

monthly

distributions

is

sourced

or

comprised

of

elements

other

than

income,

including

COMMON

SHARE

DISTRIBUTION

INFORMATION

FOR

NDMO

NDMO

makes

regular

cash

distributions

to

shareholders

of

a

stated

dollar

amount

per

share.

Subject

to

approval

and

oversight

by

the

Board

of

Trustees,

the

Fund

seeks

to

maintain

a

stable

distribution

level

designed

to

deliver

the

long-term

return

potential

of

the

Fund’s

investment

strategy

through

regular

distributions

(a

“Managed

Distribution

Program”).

The

practice

of

maintaining

a

stable

distribution

level

had

no

material

effect

on

the

Fund’s

investment

strategy

during

the

most

recent

fiscal

period

and

is

not

expected

to

have

such

an

effect

in

future

periods,

however,

distributions

in

excess

of

Fund

returns

will

cause

its

NAV

per

share

to

erode.

For

additional

information,

refer

to

the

distribution

information

section

below

and

in

the

Notes

to

Financial

Statements

herein.

This

notice

provides

shareholders

with

information

regarding

fund

distributions,

as

required

by

current

securities

laws.

You

should

not

draw

any

conclusions

about

the

Fund’s

investment

performance

from

the

amount

of

this

distribution

or

from

the

terms

of

the

Fund’s

Managed

Distribution

Policy.

The

following

table

provides

estimates

of

the

Fund’s

distribution

sources,

reflecting

year-to-date

cumulative

experience

through

the

month-end

prior

to

the

latest

distribution.

The

Fund

attributes

these

estimates

equally

to

each

regular

distribution

throughout

the

year.

Consequently,

the

estimated

information

as

of

the

specified

month-end

shown

below

is

for

the

current

distribution,

and

also

represents

an

updated

estimate

for

all

prior

months

in

the

year.

It

is

estimated

that

the

Fund

has

distributed

more

than

its

income

and

net

realized

capital

gains;

therefore,

a

portion

of

the

distributions

may

be

(and

is

shown

below

as

being

estimated

to

be)

a

return

of

capital.

A

return

of

capital

may

occur,

for

example,

when

some

or

all

of

the

money

that

you

invested

in

the

Fund

is

paid

back

to

you.

A

return

of

capital

distribution

does

not

necessarily

reflect

the

Fund’s

investment

performance

and

should

not

be

confused

with

“yield”

or

“income.”

Taxable-

Yield

represents

in

to

the

of

on

on

a

federal

tax

rate

of

40.8%.

Your

actual

federal

tax

rate

may

differ

from

the

assumed

rate.

The

also

takes

into

the

of

the

Fund’s

income

generated

and

paid

by

the

Fund

(based

on

payments

made

during

the

previous

calendar

year)

that

was

not

exempt

from

federal

income

tax.

Separately,

if

the

comparison

were

instead

to

that

generate

qualified

income,

which

is

taxable

at

a

rate

lower

than

rate,

the

Various

funds

and

accounts

managed

by

Nuveen,

including

the

Fund,

collectively

are

a

substantial

minority

holder

of

ENGH’s

outstanding

shares

of

common

stock,

and

possess

certain

other

rights

with

respect

to

the

corporate

governance

of

ENGH.

Due

to

these

facts,

under

the

federal

securities

laws,

the

securities

of

ENGH

held

by

Nuveen

funds

and

accounts,

including

the

Fund,

cannot

be

sold

except

under

limited

conditions

(which

are

not  currently

satisfied).

The

Fund

is

therefore

unable

to

sell

such

shares

in

ordinary

secondary

market

transactions

at

this

time.

On

March

6,

2023

Vistra

Corp.

(“Vistra”)

announced

that

it

has

executed

a

definitive

agreement

with

Energy

Harbor

Corp.,

pursuant

to

which

Energy

Harbor

will

merge

with

and

into

a

newly-formed

subsidiary

of

Vistra.  The

companies

anticipate

closing

the

transaction

in

the

second

half

of

2023.  In

connection

with

the

transaction,

Nuveen

funds

and

accounts

expect

to

receive

a

combination

of

cash

and

shares

in

a

newly

formed

entity.

Nuveen

expects

these

shares

to

be

issued

in

a

private

transaction

and

may

have

reduced

secondary

market

liquidity.  The

transaction

is

subject

to

certain

regulatory

approvals

and

there

can

be

no

assurance

that

the

transaction

will

close.

Various

funds

and

accounts

managed

by

Nuveen,

including

the

Fund,

collectively

are

a

substantial

minority

holder

of

ENGH’s

outstanding

shares

of

common

stock,

and

possess

certain

other

rights

with

respect

to

the

corporate

governance

of

ENGH.

Due

to

these

facts,

under

the

federal

securities

laws,

the

securities

of

ENGH

held

by

Nuveen

funds

and

accounts,

including

the

Fund,

cannot

be

sold

except

under

limited

conditions

(which

are

not  currently

satisfied).

The

Fund

is

therefore

unable

to

sell

such

shares

in

ordinary

secondary

market

transactions

at

this

time.

On

March

6,

2023

Vistra

Corp.

(“Vistra”)

announced

that

it

has

executed

a

definitive

agreement

with

Energy

Harbor

Corp.,

pursuant

to

which

Energy

Harbor

will

merge

with

and

into

a

newly-

formed

subsidiary

of

Vistra.  The

companies

anticipate

closing

the

transaction

in

the

second

half

of

2023.  In

connection

with

the

transaction,

Nuveen

funds

and

accounts

expect

to

receive

a

combination

of

cash

and

shares

in

a

newly

formed

entity.

Nuveen

expects

these

shares

to

be

issued

in

a

private

transaction

and

may

have

reduced

secondary

market

liquidity.  The

transaction

is

subject

to

certain

regulatory

approvals

and

there

can

be

no

assurance

that

the

transaction

will

close.

Senior

loans

generally

pay

interest

at

rates

which

are

periodically

adjusted

by

reference

to

a

base

short-term,

floating

lending

rate

(Reference

Rate)

plus

an

assigned

fixed

rate

(Spread).

These

floating

lending

rates

are

generally

(i)

the

lending

rate

referenced

by

the

London

Offered

Rate

("LIBOR"),

or

(ii)

the

prime

rate

offered

by

one

or

more

major

United

banks.

Senior

loans

may

be

considered

restricted

in

that

the

Fund

ordinarily

is

contractually

obligated

to

receive

approval

from

the

agent

bank

and/or

borrower

prior

to

the

disposition

of

a

senior

loan.

The

rate

shown

is

the

as

of

the

of

the

(13)

Senior

loans

generally

are

subject

to

mandatory

and/or

optional

prepayment.

Because

of

these

mandatory

prepayment

conditions

and

because

there

may

be

significant

economic

incentives

for

a

borrower

to

prepay,

prepayments

of

senior

loans

may

occur.

As

a

result,

the

actual

remaining

maturity

of

senior

loans

held

may

be

substantially

less

than

the

stated

maturities

shown.

Various

including

the

collectively

are

ENGH’s

outstanding

shares

of

common

stock,

and

possess

certain

other

with

respect

to

Due

to

facts,

under

the

held

by

and

accounts,

including

the

under

limited

conditions

(which

are

The

is

therefore

at

On

Vistra

(“Vistra”)

announced

that

it

has

executed

a

agreement

with

Energy

Corp.,

pursuant

to

which

Energy

Harbor

will

merge

with

and

into

a

subsidiary

of

Vistra.  The

anticipate

closing

the

transaction

in

the

second

half

of

2023.  In

connection

with

the

transaction,

Nuveen

funds

and

accounts

expect

to

receive

a

combination

of

cash

and

shares

in

a

newly

formed

entity.

Nuveen

expects

these

shares

to

be

issued

in

a

private

transaction

and

may

have

reduced

secondary

market

liquidity.  The

transaction

is

subject

to

certain

regulatory

approvals

and

there

can

be

no

assurance

that

the

transaction

will

close.

AMR

("AMR"),

filed

On

December

9,

2013,

AMR

emerged

from

with

the

acceptance

of

its

by

the

bankruptcy

court.

Under

the

agreement

to

meet

AMR's

obligations,

the

bondholders

including

the

received

a

distribution

of

AAL

stock

which

was

converted

to

AAL

common

stock

over

a

120-day

period.

Every

30

days,

a

quarter

of

the

preferred

stock

was

converted

to

AAL

based

on

Various

funds

managed

by

Nuveen,

including

the

Fund,

collectively

are

a

substantial

minority

holder

of

ENGH’s

outstanding

shares

of

common

stock,

and

possess

certain

other

rights

with

respect

to

the

corporate

governance

of

ENGH.

Due

to

these

facts,

under

the

federal

securities

laws,

the

securities

of

ENGH

held

by

Nuveen

funds

and

accounts,

including

the

cannot

be

sold

except

under

limited

conditions

(which

are

not  currently

satisfied).

The

is

therefore

unable

to

such

shares

in

secondary

at

this

time.

Vistra

Corp.

(“Vistra”)

announced

that

it

agreement

with

Energy

Corp.,

pursuant

to

which

Energy

Harbor

will

merge

with

and

into

a

newly-formed

subsidiary

of

Vistra.  The

companies

anticipate

closing

the

transaction

in

the

second

half

of

2023.  In

connection

with

the

transaction,

Nuveen

funds

and

accounts

expect

to

receive

a

combination

of

cash

and

shares

in

a

newly

formed

entity.

Nuveen

expects

these

shares

to

be

issued

in

a

private

transaction

and

may

have

reduced

secondary

market

liquidity.  The

transaction

is

subject

to

certain

regulatory

approvals

and

there

can

be

no

assurance

that

the

transaction

will

close.

Investment

Adviser

and

Sub-Adviser:

The

Funds'

investment

adviser

is

Nuveen

Fund

Advisors,

LLC

(the

“Adviser”),

a

subsidiary

of

Nuveen,

LLC

(“Nuveen”).

Nuveen

is

the

investment

management

arm

of

Teachers

Insurance

and

Annuity

Association

of

America

(TIAA).

The

Adviser

has

overall

responsibility

of

the

Funds,

oversees

the

management

of

the

Funds'

portfolio,

manages

the

Funds'

Fund

Reorganization

and

Mergers:

Effective

prior

to

the

opening

of

business

on

June

6,

2022,

Nuveen

Enhanced

Municipal

Value

Fund

(NEV)

(the

“Target

Fund”)

was

reorganized

into

Nuveen

Municipal

Credit

Income

Fund

(“NZF”

or

the

“Acquiring

Fund”),

(the

“Reorganization”).

Upon

the

closing

of

the

Reorganization,

the

Target

Fund

transferred

its

assets

to

the

Acquiring

Fund

in

exchange

for

common

shares

of

the

Acquiring

Fund

and

the

assumption

by

the

Acquiring

Fund

of

the

liabilities

of

the

Target

Fund.

The

Target

Fund

was

then

dissolved

and

terminated

in

accordance

with

its

Declaration

of

Trust.

Shareholders

of

the

Target

Fund

became

shareholders

of

the

Acquiring

Fund.

Holders

of

common

shares

of

the

Target

Fund

received

newly

issued

common

shares

of

the

Acquiring

Fund,

the

aggregate

net

asset

value

(“NAV”)

of

which

was

equal

to

the

aggregate

NAV

of

the

common

shares

of

the

Target

Fund

held

immediately

prior

to

the

Reorganization

(including

for

this

purpose

fractional

Acquiring

Fund

shares

to

which

shareholders

were

entitled).

For

accounting

and

performance

reporting

purposes,

the

Acquiring

Fund

was

the

survivor

of

the

reorganization.

Effective

prior

to

the

opening

of

business

on

April

17,

2023,

Nuveen

Ohio

Quality

Municipal

Income

Fund

(NUO)

and

Nuveen

Georgia

Quality

Municipal

Income

Fund

(NKG)

(the

“Target

Funds”)

were

each

merged

into

NZF

(the

“Acquiring

Fund”)

(each

a

“Merger”).

With

respect

to

each

Merger

of

a

Target

Fund

with

and

into

the

Acquiring

Fund,

the

separate

legal

existence

of

the

Target

Fund

ceased

for

all

purposes

and

the

Acquiring

Fund

succeeded

to

all

the

assets

and

assumed

all

the

liabilities

of

the

Target

Fund.

Shares

of

the

Target

Fund

were

Developments

Regarding

the

Funds’

Control

Share

By-Law:

On

October

5,

2020,

the

Funds

and

certain

other

closed-end

funds

in

the

Nuveen

fund

complex

amended

their

by-laws.

Among

other

things,

the

amended

by-laws

included

provisions

pursuant

to

which,

in

summary,

a

shareholder

who

obtains

beneficial

ownership

of

common

shares

in

a

Control

Share

Acquisition

(as

defined

in

the

by-laws)

shall

have

the

same

voting

rights

as

other

common

shareholders

only

to

the

extent

authorized

by

the

other

disinterested

shareholders

(the

“Control

Share

By-Law”).

On

January

14,

2021,

a

shareholder

of

certain

Nuveen

closed-end

funds

filed

a

civil

complaint

in

the

U.S.

District

Court

for

the

Southern

District

of

New

York

(the

“District

Court”)

against

certain

Nuveen

funds

and

their

trustees,

seeking

a

declaration

that

such

funds’

Control

Share

By-Laws

violate

the

1940

Act,

rescission

of

such

fund’s

Control

Share

By-Laws

and

a

permanent

injunction

against

such

funds

applying

the

Control

Share

By-Laws.

On

February

18,

2022,

the

District

Court

granted

judgment

in

favor

of

the

plaintiff’s

claim

for

rescission

of

such

funds’

Control

Share

By-Laws

and

the

plaintiff’s

declaratory

judgment

claim,

and

declared

that

such

funds’

Control

Share

By-Laws

violate

Section

18(i)

of

the

1940

Act.

Following

review

of

the

judgment

of

the

District

Court,

on

February

22,

2022,

the

Board

of

Trustees

(the

“Board”)

amended

the

Funds’

by-laws

to

provide

that

the

Funds’

Control

Share

By-Law

shall

be

of

no

force

and

effect

for

so

long

as

the

judgment

of

the

District

Court

is

effective

and

that

if

the

judgment

of

the

District

Court

is

reversed,

overturned,

vacated,

stayed,

or

otherwise

nullified,

the

Funds’

Control

Share

By-Law

will

be

automatically

reinstated

and

apply

to

any

beneficial

owner

of

common

shares

acquired

in

a

Control

Share

Acquisition,

regardless

of

whether

such

Control

Share

Acquisition

occurs

before

or

after

such

reinstatement,

for

the

duration

of

the

stay

or

upon

issuance

of

the

mandate

reversing,

overturning,

vacating

or

otherwise

nullifying

the

judgment

of

the

District

Court.

On

February

25,

2022,

the

Board

and

the

Funds

appealed

the

District

Court’s

decision

to

the

U.S.

Court

of

Appeals

for

the

Second

Circuit.

Significant

Accounting

Policies

The

accompanying

financial

statements

were

prepared

in

accordance

with

accounting

principles

generally

accepted

in

the

United

States

of

America

(“U.S.

GAAP”),

which

may

require

the

use

of

estimates

made

by

management

and

the

evaluation

of

subsequent

events.

Actual

results

may

differ

from

those

estimates.

Each

Fund

is

an

investment

company

and

follows

accounting

guidance

in

the

Financial

Accounting

Standards

Board

(“FASB”)

Accounting

Standards

Codification

946,

Financial

Services

—

Investment

Companies.

The

NAV

for

financial

reporting

purposes

may

differ

from

the

NAV

for

processing

security

and shareholder

transactions.

The

NAV

for

financial

reporting

purposes

includes

security

and

common

share

transactions

through

the

date

of

the

report.

Total

return

is

computed

based

on

the

NAV

used

for

processing

security

and

common

share

transactions.

The

following

is

a

summary

of

the

significant

accounting

policies

consistently

followed

by

the

Funds.

Compensation:

The

Funds pay

no

compensation

directly

to

those

of

its

trustees

or

to

its

officers,

all

of

whom

receive

remuneration

for

their

services

to

the

Funds

from

the

Adviser

or

its

affiliates.

The Board has

adopted

a

deferred

compensation

plan

for

independent

trustees

that

enables

trustees

to

elect

to

defer

receipt

of

all

or

a

portion

of

the

annual

compensation

they

are

entitled

to

receive

from

certain

Nuveen-advised

funds.

Under

the

plan,

deferred

amounts

are

treated

as

though

equal

dollar

amounts

had

been

invested

in

shares

of

select

Nuveen-advised

funds.

Custodian

Fee

Credit:

As

an

alternative

to

overnight

investments,

each

Fund

has

an

arrangement

with

its

custodian

bank,

State

Street

Bank

and

Trust

Company,

(the

“Custodian”)

whereby

certain

custodian

fees

and

expenses

are

reduced

by

net

credits

earned

on

each

Fund’s

cash

on

deposit

with

the

bank.

Credits

for

cash

balances

may

be

offset

by

charges

for

any

days

on

which

a

Fund

overdraws

its

account

at

the

Custodian.

The

amount

of

custodian

fee

credit

earned

by

a

Fund

is

recognized

on

the

Statement

of

Operations

as

a

component

of

“Custodian

expenses,

net.”

During

the

current

reporting

period,

the

custodian

fee

credit

earned

by

each

Fund

was

as

follows:

Distributions

to

Common

Shareholders:

Distributions

to

common shareholders

are

recorded

on

the

ex-dividend

date.

The

amount,

character

and

timing

of

distributions

are

determined

in

accordance

with

federal

income

tax

regulations,

which

may

differ

from

U.S.

GAAP.

NDMO

makes

monthly

cash

distributions

to

common

shareholders

of

a

stated

dollar

amount

per

share.

Subject

to

approval

and

oversight

by

the

Board,

the

Fund

seeks

to

maintain

a

stable

distribution

level

designed

to

deliver

the

long-term

return

potential

of

the

Fund’s

investment

strategy

through

regular

monthly

distributions

(a

“Managed

Distribution

Program”).

Total

distributions

during

a

calendar

year

generally

will

be

made

from

the

Fund’s

net

investment

income,

net

realized

capital

gains

and

net

unrealized

capital

gains

in

the

Fund’s

portfolio,

if

any.

The

portion

of

distributions

paid

attributed

to

net

unrealized

gains,

if

any,

is

distributed

from

the

Fund’s

assets

and

is

treated

by

common

shareholders

as

a

nontaxable

distribution

(“return

of

capital”)

for

tax

purposes.

In

the

event

that

total

distributions

during

a

calendar

year

exceed

the

Fund’s

total

return

on

NAV,

the

difference

will

reduce

NAV

per

share.

If

the

Fund’s

total

return

on

NAV

exceeds

total

distributions

during

a

calendar

year,

the

excess

will

be

reflected

as

an

increase

in

NAV

per

share.

The

final

determination

of

the

source

and

character

of

all

distributions

paid

by

the

Fund

during

the

fiscal

year

is

made

after

the

end

of

the

fiscal

year

and

is

reflected

in

the

financial

statements

contained

in

the

annual

report

as

of

October

31

each

year.

Indemnifications:

Under

the

Funds'

organizational

documents, their

officers

and

trustees

are

indemnified

against

certain

liabilities

arising

out

of

the

performance

of

their

duties

to

the

Funds.

In

addition,

in

the

normal

course

of

business,

the Funds

enter

into

contracts

that

provide

general

indemnifications

to

other

parties.

The

Funds'

maximum

exposure

under

these

arrangements

is

unknown

as

this

would

involve

future

claims

that

may

be

made

against

the Funds

that

have

not

yet

occurred.

However,

the Funds

have

not

had

prior

claims

or

losses

pursuant

to

these

contracts

and

expects

the

risk

of

loss

to

be

remote.

Investments

and

Investment

Income:

Securities

transactions

are

accounted

for

as

of

the

trade

date

for

financial

reporting

purposes.

Realized

gains

and

losses

on

securities

transactions

are

based

upon

the

specific

identification

method.

Investment

income

is

comprised

of

interest

income,

which

is

recorded

on

an

accrual

basis

and

includes

accretion

of

discounts

and

amortization

of

premiums

for

financial

reporting

purposes.

Investment

income

also

reflects

payment-in-kind

(“PIK”)

interest

and

paydown

gains

and

losses,

if

any.

PIK

interest

represents

income

received

in

the

form

of

securities

in

lieu

of

cash.

Investment

income

also

reflects

dividend

income,

which

is

recorded

on

the

ex-dividend

date.

Netting

Agreements:

In

the

ordinary

course

of

business,

the

Funds

may

enter

into

transactions

subject

to

enforceable

International

Swaps

and

Derivatives

Association,

Inc.

(ISDA)

master

agreements

or

other

similar

arrangements

(“netting

agreements”).

Generally,

the

right

to

offset

in

netting

agreements

allows

each

Fund

to

offset

certain

securities

and

derivatives

with

a

specific

counterparty,

when

applicable,

as

well

as

any

collateral

received

or

delivered

to

that

counterparty

based

on

the

terms

of

the

agreements.

Generally,

each

Fund

manages

its

cash

collateral

and

securities

collateral

on

a

counterparty

basis.

With

respect

to

certain

counterparties,

in

accordance

with

the

terms

of

the

netting

agreements,

collateral

posted

to

the

Funds

is

held

in

a

segregated

account

by

the

Funds’

custodian

and/or

with

respect

to

those

amounts

which

can

be

sold

or

repledged,

are

presented

in

Update

("ASU")

2020-04,

Reference

Rate

Reform:

Facilitation

of

the

Effects

of

Reference

Rate

Reform

on

Financial

Reporting.

The

main

objective

of

the

new

guidance

is

to

provide

relief

to

companies

that

will

be

impacted

by

the

expected

change

in

benchmark

interest

rates,

when

participating

banks

will

no

longer

be

required

to

submit

London

Interbank

Offered

Rate

(LIBOR)

quotes

by

the

UK

Financial

Conduct

Authority

(FCA).

The

new

guidance

allows

companies

to,

provided

the

only

change

to

existing

contracts

are

a

change

to

an

approved

benchmark

interest

rate,

account

for

modifications

as

a

continuance

of

the

existing

contract

without

additional

analysis.

For

new

and

existing

contracts,

the

Funds

may

elect

to

apply

the

amendments

as

of

March

12,

2020

through

December

31,

2022.

In

December

2022,

FASB

deferred

Reference

Rate

Reform:

Deferral

of

the

Sunset

Date

of

Topic

848,

which

extends

the

application

of

the

amendments

through

December

31,

2024.

Management

has

not

yet

elected

to

apply

the

amendments,

is

continuously

evaluating

the

potential

effect

a

discontinuation

of

LIBOR

could

have

on

the

Funds’

investments

and

has

currently

determined

that

it

is

unlikely

the

ASU’s

adoption

will

have

a

significant

impact

on

the

Funds’

financial

statements

and

various

filings.

New

Accounting

Pronouncement:

In

June

2022,

the

FASB

issued

ASU

2022-03

to

clarify

the

guidance

in

Topic

affect

all

entities

that

have

ASU

2022-03

(1)

clarifies

the

guidance

in

Topic

when

measuring

the

fair

value

of

an

equity

security

subject

to

contractual

restrictions

that

prohibit

the

sale

of

security,

(2)

amends

a

related

illustrative

example,

and

(3)

introduces

new

disclosure

requirements

for

equity

securities

subject

to

contractual

sale

restrictions

that

are

measured

at

2022-03

are

effective

for

Investment

Valuation

and

Fair

Value

Measurements 

The

Funds’

investments

in

securities

are

recorded

at

their

estimated

fair

value

utilizing

valuation

methods

approved

by

the

Adviser,

subject

to

oversight

of

the Board.

Fair

value

is

defined

as

the

price

that

would

be

received

upon

selling

an

investment

or

transferring

a

liability

in

an

orderly

transaction

to

an

independent

buyer

in

the

principal

or

most

advantageous

market

for

the

investment.

U.S.

GAAP

establishes

the

three-tier

hierarchy

which

is

used

to

maximize

the

use

of

observable

market

data

and

minimize

the

use

of

unobservable

inputs

and

to

establish

classification

of

fair

value

measurements

for

disclosure

purposes.

Observable

inputs

reflect

the

assumptions

market

participants

would

use

in

pricing

the

asset

or

liability.

Observable

inputs

are

based

on

market

data

obtained

from

sources

independent

of

the

reporting

entity.

Unobservable

inputs

reflect

management’s

assumptions

about

the

assumptions

market

participants

would

use

in

pricing

the

asset

or

liability.

Unobservable

inputs

are

based

on

the

best

information

available

in

the

circumstances.

The

following

is

a

summary

of

the

three-tiered

hierarchy

of

valuation

input

levels.

Level

1

–

Inputs

are

unadjusted

and

prices

are

determined

using

quoted

prices

in

active

markets

for

identical

securities.

Level

2

–

Prices

are

determined

using

other

significant

observable

inputs

(including

quoted

prices

for

similar

securities,

interest

rates,

credit

spreads,

etc.).

Level

3

–

Prices

are

determined

using

significant

unobservable

inputs

(including

management’s

assumptions

in

determining

the

fair

value

of

investments).

A

description

of

the

valuation

techniques

applied

to

the

Funds’

major

classifications

of

assets

and

liabilities

measured

at

fair

value

follows:

Equity

securities

and

exchange-traded

funds

listed

or

traded

on

a

national

market

or

exchange

are

valued

based

on

their

last

reported sales

price

or

official

closing

price of such

market

or

exchange

on

the

valuation

date.

Foreign

equity

securities

and

registered

investment

companies

that

trade

on

a

foreign

exchange

are

valued

at

the

last

reported sales

price

or

official

closing

price

on

the

principal

exchange

where

traded,

and

converted

to

U.S.

dollars

at

the

prevailing

rates

of

exchange

on

the valuation

date.

For

events affecting

the value

of

foreign

securities

between

the

time

when

the

exchange

on

which

they

are

traded

closes

and

the

time

when

the

Funds'

net

assets

are

calculated,

such

securities

will

be

valued

at

fair

value

in

accordance

with

procedures

adopted

by

the

Adviser,

subject

to

the

oversight

of

the

Board. To

the

extent

these

securities

are

actively

traded

and

no

valuation

adjustments

are

applied,

they

are

generally

classified

as

Level

1. When

valuation

adjustments

are

applied

to

the

most

recent

last

sales

price

or

official

closing

price, these

securities

are

generally

classified

as

Level

2.

Prices

of

fixed-income

securities

are

generally

provided

by

pricing

services

approved

by

the

Adviser,

which

is

subject

to

review

by

the

Adviser

and

oversight

of

the

Board. Pricing

services

establish

a

security’s

fair

value

using

methods

that

may

include

consideration

of

the

following:

yields

or

prices

of

investments

of

comparable

quality,

type

of

issue,

coupon,

maturity

and

rating,

market

quotes

or

indications

of

value

from

security

dealers,

evaluations

of

anticipated

cash

flows

or

collateral,

general

market

conditions

and

other

information

and

analysis,

including

the

obligor’s

credit

characteristics

considered

relevant.

In

pricing

certain

securities,

particularly

less

liquid

and

lower

quality

securities,

pricing

services

may

consider

information

about

a

security,

its

issuer

or

market

activity

provided

by

the

Adviser.

These

securities

are

generally

classified

as

Level

2.

Investments

in

investment

companies

are

valued

at

their

respective

NAVs

or

share

price on

the

valuation

date

and

are

generally

classified

as

Level

1. 

For

any

portfolio

security

or

derivative

for

which

market

quotations

are

not

readily

available

or

for

which

the

Adviser

deems

the

valuations

derived

using

the

valuation

procedures

described

above

not

to

reflect

fair

value,

the

Adviser

will

determine

a

fair

value

in

good

faith

using

alternative

procedures

approved

by

the

Adviser,

subject

to

the

oversight

of

the

Board.

As

a

general

principle,

the

fair

value

of

a

security

is

the

amount

that

the

owner

might

reasonably

expect

to

receive

for

it

in

a

current

sale.

A

variety

of

factors

may

be

considered

in

determining

the

fair

value

of

such

securities,

Notes

to

Financial

Statements

(Unaudited)

(continued)

rate

certificates

(referred

to

as

“Floaters”),

in

face

amounts

equal

to

some

fraction

of

the

Underlying

Bond’s

par

amount

or

market

value,

and

(b)

an

inverse

floating

rate

certificate

(referred

to

as

an

“Inverse

Floater”)

that

represents

all

remaining

or

residual

interest

in

the

TOB

Trust.

Floaters

typically

pay

short-term

tax-exempt

interest

rates

to

third

parties

who

are

also

provided

a

right

to

tender

their

certificate

and

receive

its

par

value,

which

may

be

paid

from

the

proceeds

of

a

remarketing

of

the

Floaters,

by

a

loan

to

the

TOB

Trust

from

a

third

party

liquidity

provider

(“Liquidity

Provider”),

or

by

the

sale

of

assets

from

the

TOB

Trust.

The

Inverse

Floater

is

issued

to

a

long

term

investor,

such

as

one

or

more

Funds.

The

income

received

by

the

Inverse

Floater

holder

varies

inversely

with

the

short-term

rate

paid

to

holders

of

the

Floaters,

and

in

most

circumstances

the

Inverse

Floater

holder

bears

substantially

all

of

the

Underlying

Bond’s

downside

investment

risk

and

also

benefits

disproportionately

from

any

potential

appreciation

of

the

Underlying

Bond’s

value.

The

value

of

an

Inverse

Floater

will

be

more

volatile

than

that

of

the

Underlying

Bond

because

the

interest

rate

is

dependent

on

not

only

the

fixed

coupon

rate

of

the

Underlying

Bond

but

also

on

the

short-term

interest

paid

on

the

Floaters,

and

because

the

Inverse

Floater

essentially

bears

the

risk

of

loss

(and

possible

gain)

of

the

greater

face

value

of

the

Underlying

Bond.

The

Inverse

Floater

held

by

a

Fund

gives

the

Fund

the

right

to

(a)

cause

the

holders

of

the

Floaters

to

tender

their

certificates

at

par

(or

slightly

more

than

par

in

certain

circumstances),

and

(b)

have

the

trustee

of

the

TOB

Trust

(the

“Trustee”)

transfer

the

Underlying

Bond

held

by

the

TOB

Trust

to

the

Fund,

thereby

collapsing

the

TOB

Trust.

The

Fund

may

acquire

an

Inverse

Floater

in

a

transaction

where

it

(a)

transfers

an

Underlying

Bond

that

it

owns

to

a

TOB

Trust

created

by

a

third

party

or

(b)

transfers

an

Underlying

Bond

that

it

owns,

or

that

it

has

purchased

in

a

secondary

market

transaction

for

the

purpose

of

creating

an

Inverse

Floater,

to

a

TOB

Trust

created

at

its

direction,

and

in

return

receives

the

Inverse

Floater

of

the

TOB

Trust

(referred

to

as

a

“self-deposited

Inverse

Floater”).

A

Fund

may

also

purchase

an

Inverse

Floater

in

a

secondary

market

transaction

from

a

third

party

creator

of

the

TOB

Trust

without

first

owning

the

Underlying

Bond

(referred

to

as

an

“externally-deposited

Inverse

Floater”).

An

investment

in

a

self-deposited

Inverse

Floater

is

accounted

for

as

a

“financing”

transaction

(i.e.,

a

secured

borrowing).

For

a

self-deposited

Inverse

Floater,

the

Underlying

Bond

deposited

into

the

TOB

Trust

is

identified

in

the

Fund’s

Portfolio

of

Investments

as

“(UB)

–

Underlying

bond

of

an

inverse

floating

rate

trust

reflected

as

a

financing

transaction,”

with

the

Fund

recognizing

as

liabilities,

labeled

“Floating

rate

obligations”

on

the

Statement

of

Assets

and

Liabilities,

(a)

the

liquidation

value

of

Floaters

issued

by

the

TOB

Trust,

and

(b)

the

amount

of

any

borrowings

by

the

TOB

Trust

from

a

Liquidity

Provider

to

enable

the

TOB

Trust

to

purchase

outstanding

Floaters

in

lieu

of

a

remarketing.

In

addition,

the

Fund

recognizes

in

“Investment

Income”

the

entire

earnings

of

the

Underlying

Bond,

and

recognizes

(a)

the

interest

paid

to

the

holders

of

the

Floaters

or

on

the

TOB

Trust’s

borrowings,

and

(b)

other

expenses

related

to

remarketing,

administration,

trustee,

liquidity

and

other

services

to

a

TOB

Trust,

as

a

component

of

“Interest

expense

and

amortization

of

offering

costs”

on

the

Statement

of

Operations.

Earnings

due

from

the

Underlying

Bond

and

interest

due

to

the

holders

of

the

Floaters

as

of

the

end

of

the

reporting

period

are

recognized

as

components

of

“Receivable

for

interest”

and

“Payable

for

interest”

on

the

Statement

of

Assets

and

Liabilities,

respectively.

In

contrast,

an

investment

in

an

externally-deposited

Inverse

Floater

is

accounted

for

as

a

purchase

of

the

Inverse

Floater

and

is

identified

in

the

Fund’s

Portfolio

of

Investments

as

“(IF)

–

Inverse

floating

rate

investment.”

For

an

externally-deposited

Inverse

Floater,

a

Fund’s

Statement

of

Assets

and

Liabilities

recognizes

the

Inverse

Floater

and

not

the

Underlying

Bond

as

an

asset,

and

the

Fund

does

not

recognize

the

Floaters,

or

any

related

borrowings

from

a

Liquidity

Provider,

as

a

liability.

Additionally,

the

Fund

reflects

in

“Investment

Income”

only

the

net

amount

of

earnings

on

the

Inverse

Floater

(net

of

the

interest

paid

to

the

holders

of

the

Floaters

or

the

Liquidity

Provider

as

lender,

and

the

expenses

of

the

Trust),

and

does

not

show

the

amount

of

that

interest

paid

or

the

expenses

of

the

TOB

Trust

as

described

above

as

interest

expense

on

the

Statement

of

Operations.

Fees

paid

upon

the

creation

of

a

TOB

Trust

for

self-deposited

Inverse

Floaters

and

externally-deposited

Inverse

Floaters

are

recognized

as

part

of

the

cost

basis

of

the

Inverse

Floater

and

are

capitalized

over

the

term

of

the

TOB

Trust.

As

of

the

of

the

reporting

period,

the

aggregate

value

of

Floaters

issued

by

each

Fund’s

TOB

Trust

for

and

was

During

TOB

Trusts

are

supported

by

a

liquidity

facility

provided

by

a

Liquidity

Provider

pursuant

to

which

the

Liquidity

Provider

agrees,

in

the

event

that

Floaters

are

(a)

tendered

to

the

Trustee

for

remarketing

and

the

remarketing

does

not

occur,

or

(b)

subject

to

mandatory

tender

pursuant

to

the

terms

of

the

TOB

Trust

agreement,

to

either

purchase

Floaters

or

to

provide

the

Trustee

with

an

advance

from

a

loan

facility

to

fund

the

purchase

of

Floaters

by

the

TOB

Trust.

In

certain

circumstances,

the

Liquidity

Provider

may

otherwise

elect

to

have

the

Trustee

sell

the

Underlying

Bond

to

retire

the

Floaters

that

were

tendered

and

not

remarketed

prior

to

providing

such

a

loan.

In

these

circumstances,

the

Liquidity

Provider

remains

obligated

to

provide

a

loan

to

the

extent

that

the

proceeds

of

the

sale

of

the

Underlying

Bond

are

not

sufficient

to

pay

the

purchase

price

of

the

Floaters.

The

size

of

the

commitment

under

the

loan

facility

for

a

given

TOB

Trust

is

at

least

equal

to

the

balance

of

that

TOB

Trust’s

outstanding

Floaters

plus

any

accrued

interest.

In

consideration

of

the

loan

facility,

fee

schedules

are

in

place

and

are

charged

by

the

Liquidity

Provider(s).

Any

loans

made

by

the

Liquidity

Provider

will

be

secured

by

the

purchased

Floaters

held

by

the

TOB

Trust.

Interest

paid

on

any

outstanding

loan

balances

will

be

effectively

borne

by

the

Fund

that

owns

the

Inverse

Floaters

of

the

TOB

Trust

that

has

incurred

the

borrowing

and

may

be

at

a

rate

that

is

greater

than

the

rate

that

would

have

been

paid

had

the

Floaters

been

successfully

remarketed.

As

described

above,

any

amounts

outstanding

under

a

liquidity

facility

are

recognized

as

a

component

of

“Floating

rate

obligations”

on

the

Statement

of

Assets

and

Liabilities

by

the

Fund

holding

the

corresponding

Inverse

Floaters

issued

by

the

borrowing

TOB

Trust.

As

of

the

end

of

the

reporting

period,

there

were

no

loans

outstanding

under

any

such

facility.

Each

Fund

may

also

enter

into

shortfall

and

forbearance

agreements

(sometimes

referred

to

as

a

“recourse

arrangement”)

(TOB

Trusts

involving

such

agreements

are

referred

to

herein

as

“Recourse

Trusts”),

under

which

a

Fund

agrees

to

reimburse

the

Liquidity

Provider

for

the

Trust’s

Floaters,

in

certain

circumstances,

for

the

amount

(if

any)

by

which

the

liquidation

value

of

the

Underlying

Bond

held

by

the

TOB

Trust

may

fall

short

of

the

sum

of

the

liquidation

value

of

the

Floaters

issued

by

the

TOB

Trust

plus

any

amounts

borrowed

by

the

TOB

Trust

from

the

Liquidity

Provider,

plus

any

shortfalls

in

interest

cash

flows

(sometimes

referred

to

as

“shortfall

payments”).

Under

these

agreements,

a

Fund’s

potential

exposure

to

losses

related

to

or

on

an

Inverse

Floater

may

increase

beyond

the

value

of

the

Inverse

as

a

Fund

may

potentially

be

liable

to

fulfill

all

amounts

owed

to

holders

of

the

or

the

Liquidity

Any

such

shortfall

amount

in

the

is

recognized

as

“Unrealized

on

the

Statement

of

Assets

As

of

the

the

maximum

exposure

to

the

Floaters

issued

by

Recourse

Trusts

for

self-deposited

Inverse

Floaters

and

externally-deposited

Inverse

was

as

follows:

Zero

Securities:

A

zero

coupon

security

does

not

pay

a

regular

interest

coupon

to

its

holders

during

the

life

of

Income

to

of

to

Futures

Contracts:

Upon

execution

of

a

futures

contract,

a

Fund

is

obligated

to

deposit

cash

or

eligible

securities,

also

known

as

“initial

margin,”

into

an

account

at

its

clearing

broker

equal

to

a

specified

percentage

of

the

contract

amount.

Cash

held

by

the

broker

to

cover

initial

margin

requirements

on

open

futures

contracts,

if

any,

is

recognized

as

“Cash

collateral

at

brokers

for

investments

in

futures

contracts”

on

the

Statement

of

Assets

and

Liabilities.

Investments

in

futures

contracts

obligate

a

Fund

and

the

clearing

broker

to

settle

monies

on

a

daily

basis

representing

changes

in

the

prior

days

“mark-to-market”

of

the

open

contracts.

If

a

Fund

has

unrealized

appreciation

the

clearing

broker

would

credit

the

Fund’s

account

with

an

amount

equal

to

appreciation

and

conversely

if

a

Fund

has

unrealized

depreciation

the

clearing

broker

would

debit

the

Fund’s

account

with

an

amount

equal

to

depreciation.

These

daily

cash

settlements

are

also

known

as

“variation

margin.”

Variation

margin

is

recognized

as

a

receivable

and/or

payable

for

“Variation

margin

on

futures

contracts”

on

the

Statement

of

Assets

and

Liabilities.

During

the

period

the

futures

contract

is

open,

changes

in

the

value

of

the

contract

are

recognized

as

an

unrealized

gain

or

loss

by

“marking-to-

market”

on

a

daily

basis

to

reflect

the

changes

in

market

value

of

the

contract,

which

is

recognized

as

a

component

of

“Change

in

net

unrealized

appreciation

(depreciation)

of

futures

contracts”

on

the

Statement

of

Operations.

When

the

contract

is

closed

or

expired,

a

Fund

records

a

realized

gain

or

loss

equal

to

the

difference

between

the

value

of

the

contract

on

the

closing

date

and

value

of

the

contract

when

originally

entered

into,

which

is

recognized

as

a

component

of

“Net

realized

gain

(loss)

from

futures

contracts”

on

the

Statement

of

Operations.

Risks

of

investments

in

futures

contracts

include

the

possible

adverse

movement

in

the

price

of

the

securities

or

indices

underlying

the

contracts,

the

possibility

that

there

may

not

be

a

liquid

secondary

market

for

the

contracts

and/or

that

a

change

in

the

value

of

the

contract

may

not

correlate

with

a

change

in

the

value

of

the

underlying

AMTP

Shares

are

subject

to

restrictions

on

transfer,

generally

do

not

trade,

and

market

quotations

are

generally

not

available.

The

fair

value

of

AMTP

Shares

is

expected

to

be

approximately

their

liquidation

preference

so

long

as

the

fixed

“spread”

on

the

AMTP

Shares

remains

roughly

in

line

with

the

“spread”

being

demanded

by

investors

on

instruments

having

similar

terms

in

the

current

market

environment.

In

present

market

conditions,

the

Fund's

Adviser

has

determined

that

the

fair

value

of

AMTP

Shares

is

approximately

their

liquidation

preference,

but

their

fair

value

could

vary

if

market

conditions

change

materially.

For

financial

reporting

purposes,

the

liquidation

preference

of

AMTP

Shares

is

a

liability

and

is

recognized

as

a

component

of

“AMTP

Shares,

Net”

on

the

Statement

of

Assets

and

Liabilities.

AMTP

Share

dividends

are

treated

as

interest

payments

for

financial

reporting

purposes.

Unpaid

dividends

on

AMTP

Shares

are

recognized

as

a

component

of

“Payable

for

interest”

on

the

Statement

of

Assets

and

Liabilities.

Dividends

accrued

on

AMTP

Shares

are

recognized

as

a

component

of

“Interest

expense

and

amortization

of

offering

costs”

on

the

Statement

of

Operations.

Costs

incurred

in

connection

with

the

Fund’s

offering

of

AMTP

Shares

were

recorded

as

deferred

charges,

which

are

amortized

over

MuniFund

Preferred

Shares:

NVG,

NZF,

NMCO

and

NDMO

have

issued

and

have

outstanding

MuniFund

Preferred

(“MFP”)

Shares,

with

a

$100,000

liquidation

preference

per

share.

These

MFP

Shares

were

issued

via

private

placement

and

are

not

publicly

available.

The

Funds

are

obligated

to

redeem

their

MFP

Shares

by

the

date

as

specified

in

its

offering

documents

(“Term

Redemption

Date”),

unless

earlier

redeemed

by

the

Funds.

MFP

Shares

are

initially

issued

in

a

pre-specified

mode,

however,

MFP

Shares

can

be

subsequently

designated

as

an

alternative

mode

at

a

later

date

at

the

discretion

of

the

Funds.

The

modes

within

MFP

Shares

detail

the

dividend

mechanics

and

are

described

as

follows.

At

a

subsequent

date,

the

Funds

may

establish

additional

mode

structures

with

the

MFP

Share.

•

Variable

Rate

Remarketed

Mode

(“VRRM”)

–

Dividends

for

MFP

Shares

within

this

mode

will

be

established

by

a

remarketing

agent;

therefore,

market

value

of

the

MFP

Shares

is

expected

to

approximate

its

liquidation

preference.

Shareholders

have

the

ability

to

request

a

best-efforts

tender

of

its

shares

upon

seven

days

notice.

If

the

remarketing

agent

is

unable

to

identify

an

alternative

purchaser,

the

shares

will

be

retained

by

the

shareholder

requesting

tender

and

the

subsequent

dividend

rate

will

increase

to

its

step-up

dividend

rate.

If

after

one

consecutive

year

of

unsuccessful

remarketing

attempts,

the

Fund

will

be

required

to

designate

an

alternative

mode

or

redeem

the

shares.

Each

Fund

will

pay

a

remarketing

fee

on

the

aggregate

principal

amount

of

all

MFP

Shares

while

designated

in

VRRM.

Payments

made

by

the

Fund

to

the

remarketing

agent

are

recognized

as

“Remarketing

fees”

on

the

Statement

of

Operations.

•

Variable

Rate

Mode

(“VRM”)

–

Dividends

for

MFP

Shares

designated

in

this

mode

are

based

upon

a

short-term

index

plus

an

additional

fixed

“spread”

amount

established

at

the

time

of

issuance

or

renewal

/

conversion

of

its

mode.

At

the

end

of

the

period

of

the

mode,

the

Fund

will

be

required

to

either

extend

the

term

of

the

mode,

designate

an

alternative

mode

or

redeem

the

MFP

Shares.

The

fair

value

of

MFP

Shares

while

in

are

expected

to

approximate

their

liquidation

preference

so

long

as

the

In

conditions,

the

Adviser

has

Mode

(“VRDM”)

–

Dividends

for

MFP

designated

in

this

mode

will

be

established

by

a

remarketing

agent;

therefore,

the

market

value

of

the

MFP

Shares

is

expected

to

approximate

its

liquidation

preference.

While

in

this

mode,

shares

will

have

an

unconditional

liquidity

feature

that

enable

its

shareholders

to

require

a

liquidity

provider,

which

the

Fund

has

entered

into

a

contractual

agreement,

to

purchase

shares

in

the

event

that

the

shares

are

not

In

the

event

that

shares

within

this

are

unable

to

be

successfully

remarketed

and

are

purchased

by

the

liquidity

provider,

the

dividend

rate

will

be

the

maximum

rate

which

is

designed

to

escalate

according

to

a

specified

schedule

in

order

to

enhance

the

remarketing

agent’s

ability

to

successfully

remarket

the

shares.

Each

Fund

is

required

redeem

any

shares

that

are

still

owned

by

a

liquidity

provider

after

six

months

of

continuous,

unsuccessful

remarketing.

The

Fund

will

pay

a

and

fee

on

of

all

Payments

made

NZF’s

and

2

VRDP

Shares

are

considered

for

Series

1

and

2

VRDP

Shares,

but

is

subject

to

earlier

termination

by

either

the

Fund

or

the

holder.

During

the

special

period,

the

VRDP

Shares

will

not

be

remarketed

by

a

agent,

be

or

During

the

special

rate

period,

VRDP

dividends

will

be

set

monthly

as

a

floating

rate

based

on

the

predetermined

formula.

Following

the

period,

Special

VRDP

may

transition

to

traditional

VRDP

with

dividends

set

at

weekly

remarketings,

and

be

supported

by

designated

liquidity

provider,

or

the

Board

may

approve

a

subsequent

special

Dividends

on

the

VRDP

Shares

(which

are

treated

as

interest

payments

for

financial

reporting

purposes)

are

set

at

a

rate

established

by

a

remarketing

agent;

therefore,

the

market

value

of

the

VRDP

Shares

is

expected

to

approximate

its

liquidation

preference.

In

the

event

that

VRDP

shares

are

unable

to

be

successfully

remarketed,

the

dividend

rate

will

be

the

maximum

rate

which

is

designed

to

escalate

according

to

a

specified

schedule

in

order

to

enhance

the

remarketing

agent’s

ability

to

successfully

remarket

the

VRDP

Shares.

Subject

to

certain

conditions,

VRDP

Shares

may

be

redeemed,

in

whole

or

in

part,

at

any

time

at

the

option

of

Each

may

also

if

the

Fund

fails

to

maintain

certain

asset

coverage

requirements

and

such

failures

are

not

price

per

is

equal

shareholders

and

otherwise

comply

with

Management

Fees

and

Management

Fees: 

Each

Fund’s

management

fee

compensates

the

Adviser

for

the

overall

investment

advisory

and

administrative

services

and

general

office

facilities.

The

Sub-Adviser

is

compensated

for

its

services

to

the

Funds

from

the

management

fees

paid

to

the

Adviser.

Each

Fund’s

management

fee

consists

of

two

components

–

a

fund-level

fee,

based

only

on

the

amount

of

assets

within

each

individual

Fund,

and

a

complex-level

fee,

based

on

the

aggregate

amount

of

all

eligible

fund

assets

managed

by

the

Adviser.

This

pricing

structure

enables

each

Fund’s

shareholders

to

benefit

from

growth

in

the

assets

within

their

respective

Fund

as

well

as

from

growth

in

the

amount

of

complex-wide

assets

managed

by

the

The

(Unaudited)

(continued)

The

annual

complex-level

fee,

payable

monthly,

for

each

Fund

is

calculated

by

multiplying

the

current

complex-wide

fee

rate,

determined

according

to

the

following

schedule

by

the

Funds’

daily

managed

assets:

*

For

the

complex-level

fees,

managed

assets

include

closed-end

fund

assets

managed

by

the

Adviser

that

are

attributable

to

certain

types

of

leverage.

For

these

purposes,

leverage

includes

the

funds’

use

of

preferred

stock

and

borrowings

and

certain

investments

in

the

residual

interest

certificates

(also

called

inverse

floating

rate

securities)

in

tender

option

bond

(TOB)

trusts,

including

the

portion

of

assets

held

by

a

TOB

trust

that

has

been

effectively

financed

by

the

trust’s

issuance

of

floating

rate

securities,

subject

to

an

agreement

by

the

Adviser

as

to

certain

funds

to

limit

the

amount

of

such

assets

for

determining

managed

assets

in

certain

circumstances.

The

complex-level

fee

is

calculated

based

upon

the

aggregate

daily

managed

assets

of

all

Nuveen

open-end

and

closed-end

funds

that

constitute

‘’eligible

assets.”

Eligible

assets

do

not

include

assets

attributable

to

investments

in

other

Nuveen

funds

or

assets

in

excess

of

a

determined

amount

(originally

$2

billion)

added

to

the

Nuveen

fund

complex

in

connection

with

the

Adviser’s

assumption

of

the

management

of

the

former

First

American

Funds

effective

January

1,

2011,

but

do

not

include

certain

assets

of

certain

Nuveen

funds

that

were

reorganized

into

funds

advised

by

an

affiliate

of

the

Adviser

during

the

2019

calendar

year.

As

of

April

30,

2023,

the

complex-level

fee

for

each

Fund

was

as

follows:

Other

Transactions

with

Affiliates:

Each

Fund

is

permitted

to

purchase

or

sell

securities

from

or

to

certain

other

funds

or

accounts

managed

by

the

Sub-Adviser

(“Affiliated

Entity”)

under

specified

conditions

outlined

in

procedures

adopted

by

the

Board

("cross-trade").

These

procedures

have

been

designed

to

ensure

that

any

cross-trade

of

securities

by

the

Fund

from

or

to

an

Affiliated

Entity

by

virtue

of

having

a

common

investment

adviser

(or

affiliated

investment

adviser),

common

officer

and/or

common

trustee

complies

with

Rule

17a-7

under

the

1940

Act.

These

transactions

are

effected

at

the

current

market

price

(as

provided

by

an

independent

pricing

service)

without

incurring

broker

commissions.

During

the

current

fiscal

period,

the

Funds

engaged

in

cross-trades

pursuant

to

these

procedures

as

follows:

8.

Commitments

and

Contingencies

In

the

normal

course

of

business,

each

Fund

enters

into

a

variety

of

agreements

that

may

expose

the

Fund

to

some

risk

of

loss.

These

could

include

recourse

arrangements

for

certain

TOB

Trusts

and

certain

agreements

related

to

preferred

shares,

which

are

described

elsewhere

in

these

Notes

to

Financial

Statements.

The

risk

of

future

loss

arising

from

such

agreements,

while

not

quantifiable,

is

expected

to

be

remote.

As

of

the

end

of

the

reporting

period,

the

Funds

did

not

have

any

unfunded

commitments.

From

the

may

be

party

to

certain

legal

proceedings

in

the

ordinary

course

of

business,

including

proceedings

relating

to

the

enforcement

of

the

Funds’

rights

under

contracts.

As

of

the

end

of

the

reporting

period,

management

has

determined

that

any

legal

proceeding(s)

the

Funds

are

subject

to,

including

those

described

within

are

unlikely

to

have

Borrowing

Arrangements

Committed

Line

of

Credit:

The

Funds,

along

with

certain

other

funds

managed

by

the

Adviser

(“Participating

Funds”),

have

established

a

364-day,

$2.700

billion

standby

credit

facility

with

a

group

of

lenders,

under

which

the

Participating

Funds

may

borrow

for

temporary

purposes

(other

than

on-

going

leveraging

for

investment

purposes).

Each

Participating

Fund

is

allocated

a

designated

proportion

of

the

facility’s

capacity

(and

its

associated

costs,

as

described

below)

based

upon

a

multi-factor

assessment

of

the

likelihood

and

frequency

of

its

need

to

draw

on

the

facility,

the

size

of

the

Fund

and

its

anticipated

draws,

and

the

potential

importance

of

such

draws

to

the

operations

and

well-being

of

the

Fund,

relative

to

those

of

the

other

Funds.

A

Fund

may

effect

draws

on

the

facility

in

excess

of

its

designated

capacity

if

and

to

the

extent

that

other

Participating

Funds

have

undrawn

capacity.

The

credit

facility

expires

in

June

2023

unless

extended

or

renewed.

The

credit

facility

has

the

following

terms:

0.15%

per

annum

on

unused

commitment

amounts

and

a

drawn

interest

rate

equal

to

the

higher

of

(a)

OBFR

(Overnight

Bank

Funding

Rate)

plus

1.20%

per

annum

or

(b)

the

Fed

Funds

Effective

Rate

plus

1.20%

per

annum

on

amounts

borrowed.

The

Participating

Funds

also

incurred

a

0.05%

upfront

fee

on

the

increased

commitments

from

select

lenders.

Interest

expense

incurred

by

the

Participating

Funds,

when

applicable,

is

recognized

as

a

component

of

“Interest

expense

and

amortization

of

offering

costs”

on

the

Statement

of

Operations.

Participating

Funds

paid

administration,

legal

and

arrangement

fees,

which

are

recognized

as

a

component

of

“Interest

expense

and

amortization

of

offering

costs”

on

the

Statement

of

Operations,

and

along

with

commitment

fees,

have

been

allocated

among

such

Participating

Funds

based

upon

the

relative

proportions

of

the

facility’s

aggregate

capacity

reserved

for

them

and

other

factors

deemed

relevant

by

the

Adviser

and

the

Board

of

each

Participating

Fund.

During

the

current

fiscal

period,

the

following

Funds

utilized

this

facility.

Each

Fund’s

maximum

outstanding

balance

during

Inter-Fund

Borrowing

and

Lending

Inter-Fund

Borrowing

and

Lending:

The

SEC

has

granted

an

exemptive

order

permitting

registered

open-end

and

closed-end

Nuveen

funds

to

participate

in

an

inter-fund

lending

facility

whereby

the

Nuveen

funds

may

directly

lend

to

and

borrow

money

from

each

other

for

temporary

purposes

(e.g.,

to

satisfy

redemption

requests

or

when

a

sale

of

securities

“fails,”

resulting

in

an

unanticipated

cash

shortfall)

(the

“Inter-Fund

Program”).

The

closed-end

Nuveen

funds,

including

the

Funds

covered

by

this

shareholder

report,

will

participate

only

as

lenders,

and

not

as

borrowers,

in

the

Inter-Fund

Program

because

such

closed-end

funds

rarely,

if

ever,

need

to

borrow

cash

to

meet

redemptions.

The

Inter-Fund

Program

is

subject

to

a

number

of

conditions,

including,

among

other

things,

the

requirements

that

Notes

to

Financial

Statements

(Unaudited)

(continued)

the

Inter-Fund

Program

unless

it

receives

a

more

favorable

interest

rate

than

is

typically

available

from

a

bank

or

other

financial

institution

for

a

comparable

transaction;

(2)

no

fund

may

borrow

on

an

unsecured

basis

through

the

Inter-Fund

Program

unless

the

fund’s

outstanding

borrowings

from

all

sources

immediately

after

the

inter-fund

borrowing

total

10%

or

less

of

its

total

assets;

provided

that

if

the

borrowing

fund

has

a

secured

borrowing

outstanding

from

any

other

lender,

including

but

not

limited

to

another

fund,

the

inter-fund

loan

must

be

secured

on

at

least

an

equal

priority

basis

with

at

least

an

equivalent

percentage

of

collateral

to

loan

value;

(3)

if

a

fund’s

total

outstanding

borrowings

immediately

after

an

inter-fund

borrowing

would

be

greater

than

10%

of

its

total

assets,

the

fund

may

borrow

through

the

inter-fund

loan

on

a

secured

basis

only;

(4)

no

fund

may

lend

money

if

the

loan

would

cause

its

aggregate

outstanding

loans

through

the

Inter-Fund

Program

to

exceed

15%

of

its

net

assets

at

the

time

of

the

loan;

(5)

a

fund’s

inter-fund

loans

to

any

one

fund

shall

not

exceed

5%

of

the

lending

fund’s

net

assets;

(6)

the

duration

of

inter-

fund

loans

will

be

limited

to

the

time

required

to

receive

payment

for

securities

sold,

but

in

no

event

more

than

seven

days;

and

(7)

each

inter-fund

loan

may

be

called

on

one

business

day’s

notice

by

a

lending

fund

and

may

be

repaid

on

any

day

by

a

borrowing

fund.

In

addition,

a

Nuveen

fund

may

participate

in

the

Inter-Fund

Program

only

if

and

to

the

extent

that

such

participation

is

consistent

with

the

fund’s

investment

objective

and

investment

policies.

The

Board

is

responsible

for

overseeing

the

Inter-Fund

Program.

The

limitations

detailed

above

and

the

other

conditions

of

the

SEC

exemptive

order

permitting

the

Inter-Fund

Program

are

designed

to

minimize

the

risks

associated

with

Inter-Fund

Program

for

both

the

lending

fund

and

the

borrowing

fund.

However,

no

borrowing

or

lending

activity

is

without

risk.

When

a

fund

borrows

money

from

another

fund,

there

is

a

risk

that

the

loan

could

be

called

on

one

day’s

notice

or

not

renewed,

in

which

case

the

fund may

have

to

borrow

from

a

bank

at

a

higher

rate

or

take

other

actions

to

payoff

such

loan

if

an

inter-fund

loan

is

not

available

from

another

fund.

Any

delay

in

repayment

to

a

lending

fund

could

result

in

a

lost

investment

opportunity

or

additional

borrowing

costs.

During

the

current

reporting

period,

none

of

the

Funds

covered

by

this

shareholder

report

have

entered

into

any

inter-fund

loan

activity.

Mergers

The

Mergers

were

structured

to

qualify

as

tax-free

reorganizations

under

the

Internal

Revenue

Code

for

tax

purposes,

and

the

Target

Funds’

shareholders

recognized

no

gain

or

for

federal

income

tax

purposes

as

a

result.

Prior

to

the

closing

of

each

Merger,

the

Target

distributed

all

Glossary

of

Terms

Used

in

this

Report

(Unaudited)

Average

Annual

Total

Return

:

This

is

a

commonly

used

method

to

express

an

investment’s

performance

over

a

particular,

usually

multi-year

time

period.

It

expresses

the

return

that

would

have

been

necessary

each

year

to

equal

the

investment’s

actual

cumulative

performance

(including

change

in

NAV

or

offer

price

and

reinvested

dividends

and

capital

gains

distributions,

if

any)

over

the

time

period

being

considered.

Duration:

Duration

is

a

measure

of

the

expected

period

over

which

a

bond’s

principal

and

interest

will

be

paid,

and

consequently

is

a

measure

of

the

sensitivity

of

a

bond’s

or

bond

fund’s

value

to

changes

when

market

interest

rates

change.

Generally,

the

longer

a

bond’s

or

fund’s

duration,

the

more

the

price

of

the

bond

or

fund

will

change

as

interest

rates

change.

Effective

Leverage:

Effective

leverage

is

a

fund’s

effective

economic

leverage,

and

includes

both

regulatory

leverage

(see

leverage)

and

the

leverage

effects

of

certain

derivative

investments

in

the

fund’s

portfolio.

Currently,

the

leverage

effects

of

Tender

Option

Bond

(TOB)

inverse

floater

holdings

are

included

in

effective

leverage

values,

in

addition

to

any

regulatory

leverage.

Industrial

Development

Revenue

Bond

(IDR):

A

unique

type

of

revenue

bond

issued

by

a

state

or

local

government

agency

on

behalf

of

a

private

sector

company

and

intended

to

build

or

acquire

factories

or

other

heavy

equipment

and

tools.

Inverse

Floating

Rate

Securities:

Inverse

floating

rate

securities

are

the

residual

interest

in

a

tender

option

bond

(TOB)

trust,

sometimes

referred

to

as

“inverse

floaters”,

are

created

by

depositing

a

municipal

bond,

typically

with

a

fixed

interest

rate,

into

a

special

purpose

trust.

This

trust,

in

turn,

(a)

issues

floating

rate

certificates

typically

paying

short-term

tax-exempt

interest

rates

to

third

parties

in

amounts

equal

to

some

fraction

of

the

deposited

bond’s

par

amount

or

market

value,

and

(b)

issues

an

inverse

floating

rate

certificate

(sometimes

referred

to

as

an

“inverse

floater”)

to

an

investor

(such

as

a

fund)

interested

in

gaining

investment

exposure

to

a

long-term

municipal

bond.

The

income

received

by

the

holder

of

the

inverse

floater

varies

inversely

with

the

short-

term

rate

paid

to

the

floating

rate

certificates’

holders,

and

in

most

circumstances

the

holder

of

the

inverse

floater

bears

substantially

all

of

the

underlying

bond’s

downside

investment

risk.

The

holder

of

the

inverse

floater

typically

also

benefits

disproportionately

from

any

potential

appreciation

of

the

underlying

bond’s

value.

Hence,

an

inverse

floater

essentially

represents

an

investment

in

the

underlying

bond

on

a

leveraged

basis.

Leverage:

Leverage

is

created

whenever

a

fund

has

investment

exposure

(both

reward

and/or

risk)

equivalent

to

more

than

100%

of

the

investment

capital.

Net

Asset

Value

(NAV)

Per

Share:

A

fund’s

Net

Assets

is

equal

to

its

total

assets

(securities,

cash,

accrued

earnings

and

receivables)

less

its

total

liabilities.

NAV

per

share

is

equal

to

the

fund’s

Net

Assets

divided

by

its

number

of

shares

outstanding.

Pre-Refunded

Bond/Pre-Refunding

:

Pre-Refunded

Bond/Pre-Refunding,

also

known

as

advanced

refundings

or

refinancings,

is

a

procedure

used

by

state

and

local

governments

to

refinance

municipal

bonds

to

lower

interest

expenses.

The

issuer

sells

new

bonds

with

a

lower

yield

and

uses

the

proceeds

to

buy

U.S.

Treasury

securities,

the

interest

from

which

is

used

to

make

payments

on

the

higher-yielding

bonds.

Because

of

this

collateral,

pre-refunding

generally

raises

a

bond’s

credit

rating

and

thus

its

value.

Regulatory

Leverage:

Regulatory

leverage

consists

of

preferred

shares

issued

by

or

borrowings

of

a

fund.

Both

of

these

are

part

of

a

fund’s

capital

structure.

Regulatory

leverage

is

subject

to

asset

coverage

limits

set

in

the

Investment

Company

Act

of

1940.

Tax

Obligation/General

Bonds:

Bonds

backed

by

the

general

revenues

of

an

issuer,

including

taxes,

where

the

issuer

has

the

ability

to

increase

taxes

by

an

unlimited

amount

to

pay

the

bonds

back.

Tax

Obligation/Limited

Bonds:

Bonds

backed

by

the

general

revenues

of

an

issuer,

including

taxes,

where

the

issuer

doesn’t

have

the

ability

to

increase

taxes

by

an

unlimited

amount

to

pay

the

bonds

back

.

Total

Investment

Exposure:

Total

investment

exposure

is

a

fund’s

assets

managed

by

the

Adviser

that

are

attributable

to

financial

leverage.

For

these

purposes,

financial

leverage

includes

a

fund’s

use

of

preferred

stock

and

borrowings

and

investments

in

the

residual

interest

certificates

(also

called

inverse

floating

rate

securities)

in

tender

option

bond

(TOB)

trusts,

including

the

portion

of

assets

held

by

a

TOB

trust

that

has

been

effectively

financed

by

the

trust’s

issuance

of

floating

rate

securities.

Zero

Coupon

Bond:

A

zero

coupon

bond

does

not

pay

a

regular

interest

coupon

to

its

holders

during

the

life

of

the

bond.

Income

to

the

holder

of

the

bond

comes

from

accretion

of

the

difference

between

the

original

purchase

price

of

the

bond

at

issuance

and

the

par

value

of

the

bond

at

maturity

and

is

effectively

paid

at

maturity.

The

market

prices

of

zero

coupon

bonds

generally

are

more

volatile

than

the

market

prices

of

bonds

that

pay

interest

periodically.
