COMMON

DISTRIBUTION

INFORMATION

The

following

information

regarding the

Funds' distributions

is

current

as

of

August

31,

2024.  Each

Fund's

distribution

levels

may

vary

over

time

based

on each

Fund's

investment

activity

and

portfolio

investment

value

changes.

During

the

current

reporting

period, each

Fund's

distributions

to

common

shareholders

were

as

shown

in

the

accompanying

table.

Each

Fund

sought

to

pay

regular

monthly

dividends

out

of

its

net

investment

income

at

a

rate

that

reflected

its

past

and

projected

net

income

performance.

To

permit

each

Fund

to

maintain

a

more

stable

monthly

dividend,

the

Fund

paid

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

reported

a

negative

undistributed

net

ordinary

income.

Refer

to

the

Notes

to

Financial

Statements

for

additional

information

regarding

the

amounts

of

undistributed

net

ordinary

income

and

undistributed

net

long-term

capital

gains

and

the

character

of

the

actual

distributions

paid

by

the

Fund

during

the

period.

Each

Fund

intends

to

distribute

all

or

substantially

all

of

its

net

investment

income

each

year

through

its

regular

monthly

distribution

and

to

distribute

realized

capital

gains

at

least

annually.

In

addition,

in

any

monthly

period,

to

maintain

its

declared

per

common

share

distribution

amount,

the

Fund

may

distribute

more

or

less

than

its

net

investment

income

during

the

period.

In

the

event

the

Fund

distributes

more

than

its

net

investment

income

during

any

yearly

period,

such

distributions

may

also

include

realized

gains

and/or

a

return

of

capital.

To

the

extent

that

a

distribution

includes

a

return

of

capital

the

NAV

per

share

may

erode.

If

a

distribution

includes

anything

other

than

net

investment

income,

the

Fund

provides

a

notice

of

the

best

estimate

of

its

distribution

sources

at

the

time

of

the

distribution

which

may

be

viewed

at

www.nuveen.com/CEFdistributions.

These

estimates

may

not

match

the

final

tax

characterization

(for

the

full

year’s

distributions)

contained

in

shareholders’

1099-DIV

forms

after

the

end

of

the

year.

distribution

divided

by

the

Fund’s

current

market

price

as

of

the

end

of

the

reporting

period.

Taxable-Equivalent

Yield

represents

the

yield

that

must

be

earned

on

a

fully

taxable

investment

in

order

to

equal

the

yield

of

the

Fund

on

an

after-tax

basis.

It

is

based

on

a

combined

federal

and

state

income

tax

rate

of

54.1%

and

51.7%

for

NXC

and

NXN,

respectively.

Your

actual

combined

federal

and

state

income

tax

rate

may

differ

from

the

assumed

rate.

The

Taxable-Equivalent

Yield

also

takes

into

account

the

percentage

of

the

Fund’s

income

generated

and

paid

by

the

Fund

(based

on

payments

made

during

the

previous

calendar

year)

that

was

either

exempt

from

federal

income

tax

but

not

from

state

income

tax

(e.g.,

income

from

an

out-of-state

municipal

bond),

or

was

exempt

from

neither

federal

nor

state

income

tax.

Separately,

if

the

comparison

were

instead

to

investments

that

generate

qualified

dividend

income,

which

is

taxable

at

a

rate

lower

than

an

individual’s

ordinary

graduated

tax

rate,

the

fund’s

Taxable-Equivalent

Yield

would

be

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

net

asset

value

(“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

shares

transactions

through

the

date

of

the

report.

Total

return

is

computed

based

on

the

NAV

used

for

processing

security

and common

shares 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

officers,

all

of

whom

receive

remuneration

for

their

services

to

the

Funds

from

the

Adviser

or

its

affiliates.

The Funds'

Board

of

Trustees

(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.

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.

The

Funds’

distribution

policy,

which

may

be

changed

by

the

Board,

is

to

make

regular

monthly

cash

distributions

to

holders

of

their

common

shares

(stated

in

terms

of

a

fixed

cents

per

common

share

dividend

distributions

rate

which

may

be

set

from

time

to

time).

Each

Fund

intends

to

distribute

all

or

substantially

all

of

its

net

investment

income

each

year through

its

regular

monthly

distribution

and

to

distribute

realized

capital

gains

at

least

annually.

In

addition,

in

any

monthly

period,

to

maintain

its

declared

per

common

share

distribution

amount,

a

Fund

may

distribute

more

or

less

than

its

net

investment

income

during

the

period.

In

the

event

a

Fund

distributes

more

than

its

net

investment

income

during

any

yearly

period,

such

distributions

may

also

include

realized

gains

and/or

a

return

of

capital.

To

the

extent

that

a

distribution

includes

a

return

of

capital

the

NAV

per

share

may

erode.

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.

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

28

Notes

to

Financial

Statements

(Unaudited)

(continued)

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

the

Funds’

Portfolio

of

Investments

or

Statement

of

Assets

and

Liabilities.

The

Funds’

investments

subject

to

netting

agreements

as

of

the

end

of

the

reporting

period,

if

any,

are

further

described

later

in

these

Notes

to

Financial

Statements.

3.

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:

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.

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,

which

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.

To

the

extent

the

inputs

are

observable

and

timely,

the

values

would

be

classified

as

Level

2;

otherwise

they

would

be

classified

as

Level

3.

The

following

table

summarizes

the

market

value

of

the

Funds’

investments

as

of

the

end

of

the

reporting

period,

based

on

the

inputs

used

to

value

them:

4.

Portfolio

Securities

Inverse

Floating

Rate

Securities:

Each

Fund

is

authorized

to

invest

in

inverse

floating

rate

securities.

An

inverse

floating

rate

security

is

created

by

depositing

a

municipal

bond

(referred

to

as

an

“Underlying

Bond”),

typically

with

a

fixed

interest

rate,

into

a

special

purpose

tender

option

bond

(“TOB”)

trust

(referred

to

as

the

“TOB

Trust”)

created

by

or

at

the

direction

of

one

or

more

Funds.

In

turn,

the

TOB

Trust

issues

(a)

floating

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.

typically

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

of

the

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”

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.

During

the

current

fiscal

period,

the

Funds

did

not

have

any

transactions

in

self-deposited

Inverse

Floaters

and/or

externally-deposited

Inverse

Floaters. 

Zero

Coupon

Securities:

A

zero

coupon

security

does

not

pay

a

regular

interest

coupon

to

its

holders

during

the

life

of

the

security.

Income

to

the

holder

of

the

security

comes

from

accretion

of

the

difference

between

the

original

purchase

price

of

the

security

at

issuance

and

the

par

value

of

the

security

at

maturity

and

is

effectively

paid

at

maturity.

The

market

prices

of

zero

coupon

securities

generally

are

more

volatile

than

the

market

prices

of

securities

that

pay

interest

periodically.

Purchases

and

Sales:

Long-term

purchases

and

sales during

the

current fiscal

period

were

as

follows:

The

Funds

may

purchase

securities

on

a

when-issued

or

delayed-delivery

basis.

Securities

purchased

on

a

when-issued

or

delayed-delivery

basis

may

have

extended

settlement

periods;

interest

income

is

not

accrued

until

settlement

date.

Any

securities

so

purchased

are

subject

to

market

fluctuation

during

this

period. If

a

Fund

has

outstanding

when-issued/delayed-delivery

purchases

commitments

as

of

the

end

of

the

reporting

period,

such

amounts

are

recognized

on

the

Statement

of

Assets

and

Liabilities.

Derivative

Investments

Each

Fund

is

authorized

to

invest

in

certain

derivative

instruments.

As

defined

by

U.S.

GAAP,

a

derivative

is

a

financial

instrument

whose

value

is

derived

from

an

underlying

security

price,

foreign

exchange

rate,

interest

rate,

index

of

prices

or

rates,

or

other

variables.

Investments

in

derivatives

as

of

the

end

of

and/or

during

the

current

fiscal

period,

if

any,

are

included

within

the

Statement

of

Assets

and

Liabilities

and

the

Statement

of

Operations,

respectively.

Market

and

Counterparty

Credit

Risk:

In

the

normal

course

of

business

each

Fund

may

invest

in

financial

instruments

and

enter

into

financial

transactions

where

risk

of

potential

loss

exists

due

to

changes

in

the

market

(market

risk)

or

failure

of

the

other

party

to

the

transaction

to

perform

(counterparty

credit

risk).

The

potential

loss

could

exceed

the

value

of

the

financial

assets

recorded

on

the

financial

statements.

Financial

assets,

which

potentially

expose

each

Fund

to

counterparty

credit

risk,

consist

principally

of

cash

due

from

counterparties

on

forward,

option

and

swap

transactions,

when

applicable.

The

extent

of

each

Fund’s

exposure

to

counterparty

credit

risk

in

respect

to

these

financial

assets

approximates

their

carrying

value

as

recorded

on

the

Statement

of

Assets

and

Liabilities.

Each

Fund

helps

manage

counterparty

credit

risk

by

entering

into

agreements

only

with

counterparties

the

Adviser

believes

have

the

financial

resources

to

honor

their

obligations

and

by

having

the

Adviser

monitor

the

financial

stability

of

the

counterparties.

Additionally,

counterparties

may

be

required

to

pledge

collateral

daily

(based

on

the

daily

valuation

of

the

financial

asset)

on

behalf

of

each

Fund

with

a

value

approximately

equal

to

the

amount

of

any

unrealized

gain

above

a

pre-determined

threshold.

Reciprocally,

when

each

Fund

has

an

unrealized

loss,

the

Funds

have

instructed

the

custodian

to

pledge

assets

of

the

Funds

as

collateral

with

a

value

approximately

equal

to

the

amount

of

the

unrealized

loss

above

a

pre-determined

threshold.

Collateral

pledges

are

monitored

and

subsequently

adjusted

if

and

when

the

valuations

fluctuate,

either

up

or

down,

by

at

least

the

pre-determined

threshold

amount.

which

became

effective

with

the

Management

Fees

and

Other

Transactions

with

Affiliates

Management

Fees:

Each

Fund’s

management

fee

compensates

the

Adviser

for

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

Fund

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

Adviser.

The

annual

as

to

certain

funds

to

is

calculated

based

upon

the

of

all

Nuveen

open-end

and

closed-end

funds

that

constitute

‘’eligible

Borrowing

Arrangements

The

Funds,

along

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

2025

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

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

(1)

no

fund

may

borrow

or

lend

money

through

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.

Notes

to

Financial

Statements

(Unaudited)

(continued)

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.

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.

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.

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.

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.

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

issuance

of

Process

At

held

on

and

19,

2024

(the

“Meeting”),

the

Boards

of

Trustees

(collectively,

the

“Board”

and

each

Trustee,

a

“Board

Member”)

of

the

Funds

approved,

for

their

respective

Fund,

the

renewal

of

the

investment

management

agreement

(each

an

“Investment

Agreement”)

with

Nuveen

Fund

Advisors,

LLC

(“NFAL”;

NFAL

is

an

“Adviser”)

pursuant

to

which

NFAL

serves

as

investment

adviser

to

such

Fund.

Similarly,

for

each

the

Board

approved

the

renewal

of

the

sub-advisory

agreement

(each

a

“Sub-Advisory

Agreement”)

with

Nuveen

(the

“Sub-Adviser”)

pursuant

to

which

the

serves

as

the

to

such

The

Board

Members

are

not

“interested

persons”

(as

defined

under

the

Investment

Company

Act

of

1940

(the

“1940

Act”))

and,

therefore,

the

Board

is

deemed

to

be

comprised

of

all

disinterested

Board

Members.

References

to

the

Board

and

the

Board

Members

are

Below

is

a

summary

of

the

annual

review

process

the

Board

undertook

related

to

its

most

recent

renewal

of

each

Investment

Management

Agreement

and

Sub-Advisory

Agreement

on

behalf

of

the

applicable

Fund.

In

accordance

with

applicable

law,

following

up

to

an

initial

two-year

period,

the

Board

considers

the

renewal

of

each

Investment

Management

Agreement

and

Sub-Advisory

Agreement

on

behalf

of

the

applicable

Fund

on

an

annual

basis.

The

Investment

Management

Agreements

and

Sub-

Advisory

Agreements

are

collectively

referred

to

as

the

“Advisory

Agreements,”

and

NFAL

and

the

Sub-Adviser

are

collectively,

the

“Fund

Advisers”

and

each

a

“Fund

Adviser.”

In

addition,

the

fund

complex

consists

of

the

group

of

funds

advised

by

NFAL

(collectively

referred

to

as

the

“Nuveen

funds”)

and

the

group

of

funds

advised

by

Teachers

Advisors,

LLC

(“TAL”

and

such

funds

are

collectively,

the

“TC

funds”).

For

clarity,

NFAL

serves

as

Adviser

to

the

Nuveen

funds,

including

the

Funds,

and

TAL

serves

as

“Adviser”

to

the

TC

funds.

The

Board

Members

considered

that

the

prior

separate

boards

of

the

TC

funds

and

Nuveen

funds

were

consolidated

effective

in

January

2024.

Accordingly,

at

the

Meeting,

the

Board

Members

considered

the

review

of

the

advisory

agreements

for

the

Nuveen

funds

as

well

as

reviewed

the

investment

management

agreements

for

the

TC

funds.

Depending

on

the

appropriate

context,

references

to

“the

Adviser”

may

be

to

NFAL

with

respect

to

the

Nuveen

funds

and/or

TAL

with

respect

to

the

TC

funds.

The

Board

Members

considered

the

review

of

the

advisory

agreements

of

the

Nuveen

funds

and

the

TC

funds

to

be

an

ongoing

process.

The

Board

Members

therefore

employed

the

accumulated

information,

knowledge

and

experience

they

had

gained

during

their

tenure

on

the

respective

board

of

the

TC

funds

or

Nuveen

funds

(as

the

case

may

be)

governing

the

applicable

funds

and

working

with

the

respective

investment

advisers

and

sub-

advisers,

as

applicable,

in

their

review

of

the

advisory

agreements

for

the

fund

complex.

During

the

course

of

the

year

prior

to

the

Meeting,

the

Board

and/or

its

committees

received

a

wide

variety

of

materials

that

covered

a

range

of

topics

relevant

to

the

Board’s

annual

consideration

of

the

renewal

of

the

advisory

agreements,

including

reports

on

fund

investment

results

over

various

periods;

product

initiatives

for

various

funds;

fund

expenses;

compliance,

regulatory

and

risk

management

matters;

trading

practices,

including

soft

dollar

arrangements

(as

applicable);

the

liquidity

and

derivatives

risk

management

programs;

management

of

distributions;

valuation

of

securities;

payments

to

financial

intermediaries

(as

applicable);

securities

and

with

respect

to

closed-end

and

the

trading

of

the

and

also

met

periodically

with

and/or

received

presentations

by

key

investment

professionals

managing

a

fund’s

portfolio.

In

particular,

at

the

Board

meeting

held

on

February

27-29,

2024

(the

“February

Meeting”),

the

Board

and/or

its

Investment

Committee

received

the

annual

performance

review

of

the

funds

as

described

in

further

detail

below.

The

presentations,

discussions

and

meetings

throughout

the

year

also

provide

a

means

for

the

Board

to

evaluate

and

consider

the

level,

breadth

and

quality

of

services

provided

by

the

Adviser

and

sub-advisers,

as

applicable,

and

how

such

services

have

changed

over

time

in

light

of

new

or

modified

regulatory

requirements,

changes

to

market

conditions

or

other

factors.

In

connection

with

its

annual

consideration

of

the

advisory

agreements,

the

Board,

through

its

independent

legal

counsel,

requested

and

received

extensive

materials

and

information

prepared

specifically

for

its

review

of

the

advisory

agreements.

The

materials

provided

at

the

Meeting

and/or

prior

meetings

covered

a

wide

range

of

matters

including,

but

not

limited

to,

a

description

of

the

nature,

extent

and

quality

of

services

provided

by

the

Fund

Advisers;

the

consolidation

of

the

Nuveen

fund

family

and

TC

fund

family;

a

review

of

product

advanced

in

2023

for

the

benefit

of

particular

funds

and/or

the

fund

complex;

a

review

of

each

sub-adviser,

if

applicable,

and/or

applicable

investment

team;

an

analysis

of

fund

performance

with

a

focus

on

funds

considered

to

have

met

certain

challenged

performance

measurements;

an

analysis

of

the

fees

and

expense

ratios

of

the

funds

with

a

focus

on

funds

considered

to

have

certain

expense

characteristics;

a

list

of

management

fee

and,

if

applicable,

sub-advisory

fee

schedules;

a

description

of

portfolio

manager

compensation;

an

overview

of

the

primary

and

secondary

markets

for

the

Nuveen

closed-end

funds

(including,

among

other

things,

premium

or

discount

data

and

commentary

regarding

the

leverage

management,

share

repurchase

and

shelf

offering

programs

during

2023);

a

description

of

the

profitability

and/or

financial

data

of

Nuveen,

TAL

and

the

sub-advisers;

and

a

description

of

indirect

benefits

received

by

the

Adviser

and

the

sub-advisers

as

a

result

of

their

relationships

with

the

funds,

as

applicable.

The

Board

also

considered

information

provided

by

Broadridge

Financial

Solutions,

Inc.

(“Broadridge”),

an

independent

provider

of

investment

company

data,

comparing

fee

and

expense

levels

of

each

respective

fund

to

those

of

a

peer

universe.

The

information

prepared

specifically

for

the

annual

review

supplemented

the

information

provided

to

the

Board

and

its

committees

and

the

evaluations

of

the

funds

by

the

Board

and

its

committees

during

the

year.

The

Board’s

review

of

the

advisory

agreements

for

the

fund

complex

is

based

on

all

the

information

provided

to

the

Board

and

its

committees

over

time.

The

performance,

fee

and

expense

data

and

other

information

provided

by

a

Fund

Adviser,

Broadridge

or

other

service

providers

were

not

independently

verified

by

the

Board

Members.

39

As

part

of

their

review,

the

Board

Members

and

independent

legal

counsel

met

by

videoconference

in

executive

session

on

April

10,

2024

(the

“April

Executive

Session”)

to

review

and

discuss

materials

provided

in

connection

with

their

annual

review

of

the

advisory

agreements

for

the

fund

complex.

After

reviewing

this

information,

the

Board

Members

requested,

directly

or

through

independent

legal

counsel,

additional

information,

and

the

Board

subsequently

reviewed

and

discussed

the

responses

to

these

follow-up

questions

and

requests.

The

Board

Members

were

advised

by

independent

legal

counsel

during

the

annual

review

process

as

well

as

throughout

the

year,

including

meeting

in

executive

sessions

with

such

counsel

at

which

no

representatives

of

management

were

present.

In

connection

with

their

annual

review,

the

Board

Members

also

received

a

memorandum

from

independent

legal

counsel

outlining

their

fiduciary

duties

and

legal

standards

in

reviewing

the

Advisory

Agreements,

including

guidance

from

court

cases

evaluating

advisory

fees.

The

Board’s

decisions

to

renew

each

Advisory

Agreement

were

not

based

on

a

single

identified

factor,

but

rather

each

decision

reflected

the

comprehensive

consideration

of

all

the

information

provided

to

the

Board

and

its

committees

throughout

the

year

as

well

as

the

materials

prepared

specifically

in

connection

with

the

annual

review

process.

The

contractual

arrangements

may

reflect

the

results

of

prior

year(s)

of

review,

negotiation

and

information

provided

in

connection

with

the

Board’s

annual

review

of

the

funds’

advisory

arrangements

and

oversight

of

the

funds.

Each

Board

Member

may

have

attributed

different

levels

of

importance

to

the

various

factors

and

information

considered

in

connection

with

the

annual

review

process

and

may

have

placed

different

emphasis

on

the

relevant

information

year

to

year

in

light

of,

among

other

things,

changing

market

and

economic

conditions.

A

summary

of

the

principal

factors

and

information,

but

not

all

the

factors,

the

Board

considered

in

deciding

to

renew

the

Advisory

Agreements

is

set

forth

below.

A.

Nature,

Extent

and

Quality

of

Services

In

evaluating

the

renewal

of

the

Advisory

Agreements,

the

Board

Members

received

and

considered

information

regarding

the

nature,

extent

and

quality

of

the

applicable

Fund

Adviser’s

services

provided

to

each

respective

Fund

with

particular

focus

on

the

services

and

enhancements

or

changes

to

such

services

provided

during

the

last

year.

The

Board

Members

considered

the

Investment

Management

Agreements

and

the

Sub-Advisory

Agreements

separately

in

the

course

of

their

review.

With

this

approach,

they

considered

the

roles

of

NFAL

and

the

Sub-Adviser

in

providing

services

to

the

Funds.

The

Board

considered

that

the

Adviser

provides

a

wide

array

of

management,

oversight

and

other

services

to

manage

and

operate

the

applicable

funds.

The

Board

considered

the

Adviser’s

and

its

affiliates’

dedication

of

resources,

time,

people

and

capital

as

well

as

continual

program

of

improvement

and

innovation

aimed

at

enhancing

the

funds

and

fund

complex

for

investors

and

meeting

the

needs

of

an

increasingly

complex

regulatory

environment.

In

particular,

over

the

past

several

years,

the

Board

considered

the

significant

resources,

both

financial

and

personnel,

the

Adviser

and

its

affiliates

have

committed

in

working

to

consolidate

the

Nuveen

fund

family

and

TC

fund

family

under

one

centralized

umbrella.

The

Board

considered

that

the

organizational

changes

in

bringing

together

Nuveen,

its

affiliates

and

TIAA’s

(as

defined

below)

asset

management

businesses,

consolidating

the

Nuveen

and

TC

fund

families

and

other

initiatives

were

anticipated

to

provide

various

benefits

for

the

funds

through,

among

other

things,

enhanced

operating

efficiencies,

centralized

investment

leadership

and

a

centralized

shared

resources

and

support

model.

As

part

of

these

efforts,

the

boards

of

the

TC

funds

and

Nuveen

funds

were

consolidated

effective

in

January

2024.

In

addition,

in

conjunction

with

these

consolidation

efforts,

the

Board

approved

at

the

Meeting

changes

to

fee

and

breakpoint

structures

(as

applicable)

that

could

provide

cost

savings

to

participating

funds,

as

described

in

further

detail

below.

The

Board

also

reviewed

information

regarding

other

product

actions

undertaken

or

continued

by

management

in

the

2023

calendar

year

in

seeking

to

improve

the

effectiveness

of

the

organization,

the

product

line-up

as

well

as

particular

funds

through,

among

other

things,

continuing

to

review

and

optimize

the

product

line

and

gaining

efficiencies

through

mergers

and

liquidations;

reviewing

and

updating

investment

policies

and

benchmarks;

implementing

fee

waivers

and/or

expense

cap

changes

for

certain

funds;

evaluating

and

adjusting

portfolio

management

teams

as

appropriate

for

various

funds;

and

developing

policy

positions

on

a

broad

range

of

regulatory

proposals

that

may

impact

the

funds

and

communicating

with

lawmakers

and

other

regulatory

authorities

to

help

ensure

these

positions

are

considered.

In

its

review,

the

Board

considered

that

the

funds

operated

in

a

highly

regulated

industry

and

the

scope

and

complexity

of

the

services

and

resources

that

the

Adviser

and

its

affiliates

must

provide

to

manage

and

operate

the

applicable

funds

have

expanded

over

the

years

as

a

result

of,

among

other

things,

regulatory,

market

and

other

developments,

such

as

the

adoption

of

the

tailored

shareholder

report

or

the

revised

fund

name

rule.

In

considering

the

breadth

and

quality

of

services

the

Adviser

and

its

various

teams

provide,

the

Board

considered

that

the

Adviser

provides

investment

advisory

services.

With

respect

to

the

Nuveen

funds,

such

funds

utilize

sub-advisers

to

manage

the

portfolios

of

the

funds

subject

to

the

supervision

of

NFAL.

Accordingly,

the

Board

considered

that

NFAL

and

its

affiliates,

among

other

things,

oversee

and

review

the

performance

of

the

respective

sub-adviser

and

its

investment

team(s);

evaluate

Nuveen

fund

performance

and

market

conditions;

evaluate

investment

strategies

and

recommend

changes

thereto;

set

and

manage

distributions

consistent

with

the

respective

Nuveen

fund’s

product

design;

oversee

trade

execution

and,

as

applicable,

securities

lending;

evaluate

investment

risks;

and

manage

valuation

matters.

With

respect

to

closed-end

Nuveen

funds,

such

services

also

include

managing

leverage;

monitoring

asset

coverage

levels

for

leveraged

funds

and

compliance

with

rating

agency

criteria;

providing

capital

management

and

secondary

market

services

(such

as

implementing

common

share

shelf

offerings,

capital

return

programs

and

common

share

repurchases);

and

maintaining

a

closed-end

fund

investor

relations

program.

The

Board

considered

that,

with

respect

to

such

funds,

management

actively

monitors

any

discount

from

net

asset

value

per

share

at

which

the

respective

Nuveen

fund’s

common

stock

trades

and

evaluates

potential

avenues

to

mitigate

the

discount,

including

evaluating

the

level

of

distributions

that

the

fund

pays.

The

Board

further

considered

that

over

the

course

of

the

2023

calendar

year,

the

Nuveen

global

public

product

team

which

supports

the

funds

in

the

fund

complex

and

their

shareholders

assessed

the

investment

personnel

across

the

investment

leadership

teams

which

resulted

in

additions

or

other

modifications

to

the

portfolio

management

teams

of

various

funds.

The

Board

also

reviewed

a

description

of

the

compensation

structure

applicable

to

certain

portfolio

managers.

40

Statement

Regarding

Basis

for

Approval

of

Investment

Advisory

Contract

(Unaudited)

(continued)

In

addition

to

the

above

investment

advisory

services,

the

Board

further

considered

the

extensive

compliance,

regulatory,

administrative

and

other

services

the

Adviser

and

its

various

teams

or

affiliates

provide

to

manage

and

operate

the

applicable

funds.

Given

the

highly

regulated

industry

in

which

the

funds

operate,

the

Board

considered

the

breadth

of

the

Adviser’s

compliance

program

and

related

policies

and

procedures.

The

Board

reviewed

various

initiatives

the

Adviser’s

compliance

team

undertook

or

continued

in

2023,

in

part,

to

address

new

regulatory

requirements,

support

international

business

growth

and

product

development,

enhance

international

trading

capabilities,

enhance

monitoring

capabilities

in

light

of

the

new

regulatory

requirements

and

guidance

and

maintain

a

comprehensive

training

program.

The

Board

further

considered,

among

other

things,

that

other

non-advisory

services

provided

included,

among

other

things,

board

support

and

reporting;

establishing

and

reviewing

the

services

provided

by

other

fund

service

providers

(such

as

a

fund’s

custodian,

accountant,

and

transfer

agent);

risk

management,

including

reviews

of

the

liquidity

risk

management

and

derivatives

risk

management

programs;

legal

support

services;

regulatory

advocacy;

and

cybersecurity,

business

continuity

and

disaster

recovery

planning

and

testing.

Aside

from

the

services

provided,

the

Board

considered

the

financial

resources

of

the

Adviser

and/or

its

affiliates

and

their

willingness

to

make

investments

in

the

technology,

personnel

and

infrastructure

to

support

the

funds,

including

to

enhance

global

talent,

middle

office

systems,

software

and

international

and

internal

capabilities.

The

Board

considered

the

access

provided

by

the

Adviser

and

its

affiliates

to

a

seed

capital

budget

to

support

new

or

existing

funds

and/or

facilitate

changes

for

a

respective

fund.

The

Board

considered

the

benefits

to

shareholders

of

investing

in

a

fund

that

is

a

part

of

a

large

fund

complex

with

a

variety

of

investment

disciplines,

capabilities,

expertise

and

resources

available

to

navigate

and

support

the

funds

including

during

stressed

times.

The

Board

considered

the

overall

reputation

and

capabilities

of

the

Adviser

and

its

affiliates

and

the

Adviser’s

continuing

commitment

to

provide

high

quality

services.

In

its

review,

the

Board

also

considered

the

significant

risks

borne

by

the

Adviser

and

its

affiliates

in

connection

with

their

services

to

the

applicable

funds,

including

entrepreneurial

risks

in

sponsoring

and

supporting

new

funds

and

smaller

funds

and

ongoing

risks

with

managing

the

funds,

such

as

investment,

operational,

reputational,

regulatory,

compliance

and

litigation

risks.

With

respect

to

the

Funds,

the

Board

considered

the

division

of

responsibilities

between

NFAL

and

the

Sub-Adviser

and

considered

that

the

Sub-

Adviser

and

its

investment

personnel

generally

are

responsible

for

the

management

of

each

Fund’s

portfolio

under

the

oversight

of

NFAL

and

the

Board.

The

Board

considered

an

analysis

of

the

Sub-Adviser

provided

by

NFAL

which

included,

among

other

things,

a

summary

of

changes

in

the

leadership

teams

and/or

portfolio

manager

teams;

the

performance

of

the

Nuveen

funds

sub-advised

by

the

Sub-Adviser

over

various

periods

of

time;

and

data

reflecting

product

changes

(if

any)

taken

with

respect

to

certain

Nuveen

funds.

The

Board

considered

that

NFAL

recommended

the

renewal

of

the

Sub-Advisory

Agreements.

Based

on

its

review,

the

Board

determined,

in

the

exercise

of

its

reasonable

business

judgment,

that

it

was

satisfied

with

the

nature,

extent

and

quality

of

services

provided

to

the

respective

Funds

under

each

applicable

Advisory

Agreement.

B.

The

Investment

Performance

of

the

Funds

and

Fund

Advisers

In

evaluating

the

quality

of

the

services

provided

by

the

Fund

Advisers,

the

Board

also

considered

a

variety

of

investment

performance

data

of

the

Funds.

In

this

regard,

the

Board

and/or

its

Investment

Committee

reviewed,

among

other

things,

performance

of

the

Funds

over

the

quarter,

one-,

three-

and

five-year

periods

ending

December

31,

2023

and

March

31,

2024.

The

Board

performed

its

annual

review

of

fund

performance

at

its

February

Meeting

and

an

additional

review

at

the

April

Executive

Session

and

also

reviewed

and

discussed

performance

data

at

its

other

regularly

scheduled

quarterly

meetings

throughout

the

year.

The

Board

therefore

took

into

account

the

performance

data,

presentations

and

discussions

(written

and

oral)

that

were

provided

at

the

Meeting

and

in

prior

meetings

over

time

in

evaluating

fund

performance,

including

management’s

analysis

of

a

fund’s

performance

with

particular

focus

on

funds

that

met

certain

challenged

performance

measurements

as

determined

pursuant

to

a

methodology

approved

by

the

Board

or

additional

measurements

as

determined

by

management’s

investment

analysts.

As

various

Nuveen

funds

have

modified

their

portfolio

teams

and/or

made

significant

changes

to

their

portfolio

strategies

over

time,

the

Board

reviewed,

among

other

things,

certain

tracking

performance

data

over

specific

periods

comparing

performance

before

and

after

such

changes.

The

Board

considered

that

performance

data

reflects

performance

over

a

specified

period

which

may

differ

significantly

depending

on

the

ending

dates

selected,

particularly

during

periods

of

market

volatility.

Further,

the

Board

considered

that

shareholders

may

evaluate

performance

based

on

their

own

respective

holding

periods

which

may

differ

from

the

performance

periods

reviewed

by

the

Board

and

lead

to

differing

results.

In

its

evaluation,

the

Board

reviewed

fund

performance

results

from

different

perspectives.

In

general,

subject

to

certain

exceptions,

the

Board

reviewed

both

absolute

and

relative

fund

performance

over

the

various

time

periods

and

considered

performance

results

in

light

of

a

fund’s

investment

objective(s),

strategies

and

risks.

With

respect

to

the

relative

performance,

the

Board

considered

fund

performance

in

comparison

to

the

performance

of

peer

funds

(the

“Performance

Peer

Group”),

subject

to

certain

exceptions,

and

recognized

and/or

customized

benchmarks

(i.e.,

generally

benchmarks

derived

from

multiple

recognized

benchmarks).

In

reviewing

such

comparative

performance,

the

Board

was

cognizant

of

the

inherent

limitations

of

such

data

which

can

make

meaningful

performance

comparisons

generally

difficult.

As

an

illustration,

differences

in

the

composition

of

the

Performance

Peer

Group,

the

investment

objective(s),

strategies,

dates

of

fund

inception

and

other

characteristics

of

the

peers

in

the

Performance

Peer

Group,

the

level,

type

and

cost

of

leverage

(if

any)

of

the

peers,

and

the

varying

sizes

of

peers

all

may

contribute

to

differences

in

the

performance

results

of

a

Performance

Peer

Group

compared

to

the

applicable

fund.

With

respect

to

relative

performance

of

a

fund

compared

to

a

benchmark

index,

differences,

among

other

things,

in

the

investment

objective(s)

and

strategies

of

a

fund

and

the

benchmark

(particularly

an

actively

managed

fund

that

does

not

directly

follow

an

index)

as

well

as

the

costs

of

operating

a

fund

would

necessarily

contribute

to

differences

in

performance

results

and

limit

the

value

of

the

comparative

performance

information.

To

assist

the

Board

in

its

review

of

the

comparability

of

the

relative

performance,

management

generally

has

ranked

the

relevancy

of

the

Performance

Peer

Groups

to

the

Funds

as

low,

medium

or

high.

In

its

review

of

relative

performance,

the

Board

considered

a

Fund’s

performance

relative

to

its

Performance

Peer

Group,

among

other

things,

by

evaluating

its

quartile

ranking

with

the

1st

quartile

representing

the

top

performing

funds

within

the

Performance

Peer

Group

and

the

4th

quartile

representing

the

lowest

performing

funds.

41

The

Board

also

considered

that

secondary

market

trading

of

shares

of

the

Nuveen

closed-end

funds

also

continues

to

be

a

priority

for

the

Board

given

its

importance

to

shareholders,

and

therefore,

the

Board

and/or

its

Closed-end

Fund

committee

reviews

certain

performance

data

reflecting,

among

other

things,

the

premiums

and

discounts

at

which

the

shares

of

the

Nuveen

closed-end

funds

have

traded

at

various

periods

throughout

the

year.

In

its

review,

the

Board

considers,

among

other

things,

changes

to

investment

mandates

and

guidelines,

distribution

policies,

leverage

levels

and

types;

share

repurchases

and

similar

capital

market

actions;

and

effective

communications

programs

to

build

greater

awareness

and

deepen

understanding

of

closed-end

funds.

As

applicable,

the

Board

considered

the

impact

of

leverage

on

a

Nuveen

fund’s

performance.

The

Board

further

considered

that

performance

results

should

include

the

distribution

yields

of

funds

that

seek

to

provide

income

as

part

of

their

investment

objective(s)

to

shareholders.

In

this

regard,

the

Board

considered

that

the

use

of

leverage

by

various

funds

may

have

detracted

from

total

return

performance

of

such

funds

over

various

periods

in

current

market

conditions,

but

the

leverage

also

was

accretive

in

providing

higher

levels

of

income.

The

Board

evaluated

performance

in

light

of

various

relevant

factors

which

may

include,

among

other

things,

general

market

conditions,

issuer-

specific

information,

asset

class

information,

leverage

and

fund

cash

flows.

The

Board

considered

that

long-term

performance

could

be

impacted

by

even

one

period

of

significant

outperformance

or

underperformance

and

that

a

single

investment

theme

could

disproportionately

affect

performance.

Further,

the

Board

considered

that

market

and

economic

conditions

may

significantly

impact

a

fund’s

performance,

particularly

over

shorter

periods,

and

such

performance

may

be

more

reflective

of

such

economic

or

market

events

and

not

necessarily

reflective

of

management

skill.

Although

the

Board

reviews

short-,

intermediate-

and

longer-term

performance

data,

the

Board

considered

that

longer

periods

of

performance

may

reflect

full

market

cycles.

In

their

review

from

year

to

year,

the

Board

Members

consider

and

may

place

different

emphasis

on

the

relevant

information

in

light

of

changing

circumstances

in

market

and

economic

conditions.

In

evaluating

performance,

the

Board

focused

particular

attention

on

funds

with

less

favorable

performance

records.

However,

depending

on

the

facts

and

circumstances,

including

any

differences

between

the

respective

fund

and

its

benchmark

and/or

Performance

Peer

Group,

the

Board

may

be

satisfied

with

a

fund’s

performance

notwithstanding

that

its

performance

may

be

below

that

of

its

benchmark

and/or

peer

group

for

certain

periods.

With

respect

to

any

funds

for

which

the

Board

has

identified

performance

issues,

the

Board

seeks

to

monitor

such

funds

more

closely

until

performance

improves,

discuss

with

the

Adviser

the

reasons

for

such

results,

consider

whether

any

steps

are

necessary

or

appropriate

to

address

such

issues,

discuss

and

evaluate

the

potential

consequences

of

such

steps

and

review

the

results

of

any

steps

undertaken.

The

performance

determinations

with

respect

to

each

Fund

are

summarized

below.

For

Nuveen

California

Select

Tax-Free

Income

Portfolio,

the

Board

considered

that

although

the

Fund’s

performance

was

below

the

performance

of

its

benchmark

for

the

three-year

period

ended

December

31,

2023

and

the

Fund

ranked

in

the

fourth

quartile

of

its

Performance

Peer

Group

for

the

one-year

period

ended

December

31,

2023,

the

Fund

outperformed

its

benchmark

for

the

one-

and

five-

year

periods

ended

December

2023

and

ranked

in

the

first

quartile

of

its

Performance

Peer

Group

for

the

three-

and

five-year

periods

ended

December

31,

2023.

In

addition,

although

the

performance

was

below

the

performance

of

its

benchmark

for

the

three-year

period

ended

March

31,

2024,

the

Fund

outperformed

its

March

31,

2024

and

ranked

in

for

the

one-year

period

and

first

quartile

for

the

three-

and

five-year

periods

ended

March

31,

2024.

In

its

review,

the

Board

considered

that

the

Performance

Peer

Group

was

classified

as

low

for

relevancy.

On

the

basis

of

the

Board’s

ongoing

review

of

investment

performance

and

all

relevant

factors,

including

the

relative

market

conditions

during

certain

reporting

periods,

the

Fund’s

investment

objective(s)

and

management’s

discussion

of

performance,

the

Board

concluded

that

the

performance

supported

renewal

of

the

Advisory

Agreements.

1.

Fees

and

Expenses

As

part

of

its

annual

review,

the

Board

generally

reviewed,

among

other

things,

with

respect

to

the

Nuveen

closed-end

funds,

the

contractual

management

fee

and

the

actual

management

fee

(i.e.,

the

management

fee

after

taking

into

consideration

fee

waivers

and/or

expense

reimbursements,

if

any)

paid

by

a

Fund

to

the

Adviser

in

light

of

the

nature,

extent

and

quality

of

the

services

provided.

The

Board

also

reviewed

information

about

other

expenses

and

the

total

operating

expense

ratio

of

each

Fund

(after

any

fee

waivers

and/or

expense

reimbursements).

More

specifically,

the

Board

Members

reviewed,

among

other

things,

each

Fund’s

management

fee

rates

and

net

total

expense

ratio

in

relation

to

similar

data

for

a

comparable

universe

of

funds

(the

“Expense

Universe”)

established

by

Broadridge.

The

Board

Members

reviewed

the

methodology

Broadridge

employed

to

establish

its

Expense

Universe

and

considered

that

differences

between

the

applicable

fund

and

its

respective

Expense

Universe

as

well

as

changes

to

the

composition

of

the

Expense

Universe

from

year

to

year,

may

limit

some

of

the

value

of

the

comparative

data.

The

Board

Members

also

considered

that

it

can

be

difficult

to

compare

management

fees

among

funds

as

there

are

variations

in

the

services

that

are

included

for

the

fees

paid.

The

Board

Members

took

these

limitations

and

differences

into

account

when

reviewing

comparative

peer

data.

The

Board

Members

also

considered

a

Fund’s

operating

expense

ratio

as

it

more

directly

reflected

a

shareholder’s

total

costs

in

investing

in

the

respective

fund.

In

their

review,

the

Board

Members

considered,

in

particular,

each

fund

with

a

net

total

expense

ratio

(based

on

common

assets

and

excluding

investment-related

costs

such

as

the

costs

of

leverage

and

taxes

for

closed-end

funds)

meeting

certain

expense

or

fee

criteria

when

compared

to

its

Expense

Universe

and

an

analysis

as

to

the

factors

contributing

to

each

such

fund’s

relative

net

total

expense

ratio.

In

addition,

although

the

Board

reviewed

a

fund’s

net

total

expense

ratio

both

including

and

excluding

investment-

related

expenses

(e.g.,

leverage

costs)

for

certain

of

the

closed-end

funds,

the

Board

considered

that

leverage

expenses

will

vary

across

funds

and

peers

because

of

differences

in

the

forms

and

terms

of

leverage

employed

by

the

respective

fund.

Accordingly,

in

reviewing

the

comparative

data

between

a

fund

and

its

peers,

the

Board

generally

considered

the

fund’s

net

total

expense

ratio

and

fees

excluding

investment-related

costs

and

taxes

for

the

closed-end

funds.

The

Board

also

considered

that

the

use

of

leverage

for

closed-end

funds

may

create

a

conflict

of

interest

for

NFAL

and

the

applicable

sub-adviser

given

the

increase

of

assets

from

leverage

upon

which

an

advisory

or

sub-advisory

fee

is

based.

The

Board

Members

considered,

however,

that

NFAL

and

the

sub-advisers

(as

applicable)

would

seek

to

manage

the

potential

conflict

by

recommending

to

the

Board

to

leverage

the

applicable

fund

or

increase

such

leverage

when

NFAL

and/or

a

sub-

adviser,

as

applicable,

has

determined

that

such

action

would

be

in

the

best

interests

of

the

respective

fund

and

its

common

shareholders

and

by

periodically

reviewing

with

the

Board

the

fund’s

performance

and

the

impact

of

the

use

of

leverage

on

that

performance.

The

Board

Members

also

considered,

in

relevant

part,

a

Fund’s

management

fee

and

net

total

expense

ratio

in

light

of

the

Fund’s

performance

history,

including

reviewing

certain

funds

identified

by

management

and/or

the

Board

as

having

a

higher

net

total

expense

ratio

or

management

fee

compared

to

their

respective

peers

coupled

with

experiencing

periods

of

challenged

performance

and

considering

the

reasons

for

such

comparative

positions.

In

their

evaluation

of

the

fee

arrangements

for

the

Funds,

the

Board

Members

also

reviewed

the

management

fee

schedules

and

the

expense

reimbursements

and/or

fee

waivers

agreed

to

by

the

Adviser

for

the

respective

fund

(if

any).

In

its

review,

the

Board

considered

that

the

management

fees

of

the

Nuveen

funds

were

generally

comprised

of

two

components,

a

fund-level

component

and

a

complex-level

component,

each

with

its

own

breakpoint

schedule,

subject

to

certain

exceptions.

As

indicated

above,

the

Board

approved

a

revised

fee

schedule

which

would

reduce

and

streamline

the

asset

thresholds

necessary

to

meet

breakpoints

in

the

complex-level

fee

component.

The

Board

considered

that

management

anticipated

approximately

$50

million

in

savings

for

Nuveen

fund

shareholders

as

a

result

of

the

revised

fee

schedule

as

well

as

additional

estimated

savings

over

time.

The

Board

further

considered

management’s

representation

that

there

will

be

no

increase

to

any

Nuveen

fund’s

respective

advisory

agreement

fee

rate

as

a

result

of

the

revised

complex-level

fee

schedule.

In

its

review,

the

Board

considered

that

across

the

Nuveen

fund

and

TC

fund

complex,

management

estimated

that

fund-level

breakpoints

resulted

in

approximately

$82.5

million

in

reduced

fees

overall

in

2023.

In

addition,

the

Board

considered

that

management

determined

that

the

Nuveen

funds

achieved

additional

fee

reductions

of

approximately

$49

million

due

to

the

complex-wide

management

fee

structure

in

2023.

With

respect

to

the

Sub-Adviser,

the

Board

also

considered,

among

other

things,

the

sub-advisory

fee

schedule

paid

to

the

Sub-Adviser

in

light

of

the

sub-advisory

services

provided

to

the

respective

Fund.

In

its

review,

the

Board

considered

that

the

compensation

paid

to

the

Sub-Adviser

is

the

responsibility

of

NFAL,

not

the

Funds.

The

Board’s

considerations

regarding

the

comparative

fee

data

for

each

of

the

Funds

are

set

forth

below.

For

Nuveen

California

Select

Tax-Free

Income

Portfolio,

the

Fund’s

contractual

management

fee

rate,

actual

management

fee

rate

and

net

total

expense

ratio

were

below

the

Expense

Universe

median.

For

Nuveen

New

York

Select

Tax-Free

Income

Portfolio,

the

Fund’s

contractual

management

fee

rate,

actual

management

fee

rate

and

net

total

expense

ratio

were

below

the

Expense

Universe

median.

Based

on

its

review

of

the

information

provided,

the

Board

determined

that

each

Fund’s

management

fees

(as

applicable)

to

a

Fund

Adviser

were

reasonable

in

light

of

the

nature,

extent

and

quality

of

services

provided

to

the

Fund.

43

2.

Comparisons

with

the

Fees

of

Other

Clients

In

evaluating

the

appropriateness

of

fees,

the

Board

also

considered

that

the

Adviser,

affiliated

sub-advisers

and/or

their

affiliate(s)

provide

investment

management

services

to

other

types

of

clients

which

may

include:

separately

managed

accounts,

retail

managed

accounts,

foreign

funds

(UCITS),

other

investment

companies

(as

sub-advisers),

limited

partnerships

and

collective

investment

trusts.

The

Board

reviewed

the

equal

weighted

average

fee

or

other

fee

data

for

the

other

types

of

clients

managed

in

a

similar

manner

to

certain

of

the

Nuveen

funds

and

TC

funds.

The

Board

considered

the

Adviser’s

rationale

for

the

differences

in

the

management

fee

rates

of

the

funds

compared

to

the

management

fee

rates

charged

to

these

other

types

of

clients.

In

this

regard,

the

Board

considered

that

differences,

including

but

not

limited

to,

the

amount,

type

and

level

of

services

provided

by

the

Adviser

to

the

funds

compared

to

that

provided

to

other

clients

as

well

as

differences

in

investment

policies;

regulatory,

disclosure

and

governance

requirements;

servicing

relationships

with

vendors;

the

manner

of

managing

such

assets;

product

structure;

investor

profiles;

and

account

sizes

all

may

contribute

to

variations

in

relative

fee

rates.

Further,

differences

in

the

client

base,

governing

bodies,

distribution,

jurisdiction

and

operational

complexities

also

would

contribute

to

variations

in

management

fees

assessed

the

funds

compared

to

foreign

fund

clients.

In

addition,

differences

in

the

level

of

advisory

services

required

for

passively

managed

funds

also

contribute

to

differences

in

the

management

fee

levels

of

such

funds

compared

to

actively

managed

funds.

As

a

general

matter,

higher

fee

levels

reflect

higher

levels

of

service

provided

by

the

Adviser,

increased

investment

management

complexity,

greater

product

management

requirements,

and

higher

levels

of

business

risk

or

some

combination

of

these

factors.

The

Board

considered

the

wide

range

of

services

in

addition

to

investment

management

that

the

Adviser

had

provided

to

the

funds

compared

to

other

types

of

clients

as

well

as

the

increased

entrepreneurial,

legal

and

regulatory

risks

that

the

Adviser

incurs

in

sponsoring

and

managing

the

funds.

The

Board

further

considered

that

a

sub-adviser’s

fee

is

essentially

for

portfolio

management

services

and

therefore

more

comparable

to

the

fees

it

receives

for

retail

wrap

accounts

and

other

external

sub-advisory

mandates.

The

Board

concluded

that

the

varying

levels

of

fees

were

reasonable

given,

among

other

things,

the

more

extensive

services,

regulatory

requirements

and

legal

liabilities,

and

the

entrepreneurial,

legal

and

regulatory

risks

incurred

in

sponsoring

and

advising

a

registered

investment

company

compared

to

that

required

in

advising

other

types

of

clients.

3.

Profitability

of

Fund

Advisers

In

their

review,

the

Board

Members

considered

various

profitability

data

relating

to

the

Fund

Advisers’

services

to

the

Nuveen

funds.

With

respect

to

the

Nuveen

funds,

the

Board

Members

reviewed

the

estimated

profitability

information

of

Nuveen

as

a

result

of

its

advisory

services

to

the

Nuveen

funds

overall

as

well

as

profitability

data

of

certain

other

firms.

Such

profitability

information

included,

among

other

things,

gross

and

net

revenue

margins

(excluding

distribution)

of

Nuveen

Investments,

Inc.

(“Nuveen

Investments”)

for

services

to

the

Nuveen

funds

on

a

pre-tax

and

after-tax

basis

for

the

2023

and

2022

calendar

years

as

well

as

the

revenues

earned

(less

any

expense

reimbursements/fee

waivers)

and

expenses

incurred

by

Nuveen

Investments

for

its

advisory

activities

to

the

Nuveen

funds

(excluding

distribution)

for

the

2023

and

2022

calendar

years.

The

Board

Members

also

considered

the

rationale

for

the

change

in

Nuveen’s

profitability

from

2022

to

2023.

In

addition,

the

Board

reviewed

the

revenues,

expenses

and

operating

margin

(pre-

and

after-tax)

NFAL

derived

from

its

exchange-traded

fund

product

line

for

the

2023

and

2022

calendar

years.

In

developing

the

profitability

data,

the

Board

Members

considered

the

subjective

nature

of

calculating

profitability

as

the

information

is

not

audited

and

is

necessarily

dependent

on

cost

allocation

methodologies

to

allocate

expenses

throughout

the

complex

and

among

the

various

advisory

products.

Given

there

is

no

single

universally

recognized

expense

allocation

methodology

and

that

other

reasonable

and

valid

allocation

methodologies

could

be

employed

and

could

lead

to

significantly

different

results,

the

Board

reviewed,

among

other

things,

a

description

of

the

cost

allocation

methodologies

employed

to

develop

the

financial

information,

a

summary

of

the

refinements

Nuveen

had

made

to

the

methodology

that

had

occurred

over

the

years

from

2010

through

2021

to

provide

Nuveen’s

profitability

analysis,

and

a

historical

expense

analysis

of

Nuveen

Investments’

revenues,

expenses

and

pre-tax

net

revenue

margins

derived

from

its

advisory

services

to

the

Nuveen

funds

(excluding

distribution)

for

the

calendar

years

from

2017

through

2023.

The

Board

of

the

Nuveen

funds

had

also

appointed

two

Board

Members

to

serve

as

the

Board’s

liaisons

to

meet

with

representatives

of

NFAL

and

review

the

development

of

the

profitability

data

and

to

report

to

the

full

Board.

In

addition,

the

Board

considered

certain

comparative

operating

margin

data.

In

this

regard,

the

Board

reviewed

the

operating

margins

of

Nuveen

Investments

compared

to

the

adjusted

operating

margins

of

a

peer

group

of

asset

management

firms

with

publicly

available

data

and

the

most

comparable

assets

under

management

(based

on

asset

size

and

asset

composition)

to

Nuveen.

The

Board

considered

that

the

operating

margins

of

the

peers

were

adjusted

generally

to

address

that

certain

services

provided

by

the

peers

were

not

provided

by

Nuveen.

The

Board

also

reviewed,

among

other

things,

the

net

revenue

margins

(pre-tax)

of

Nuveen

Investments

on

a

company-wide

basis

and

the

net

revenue

margins

(pre-tax)

of

Nuveen

Investments

derived

from

its

services

to

the

Nuveen

funds

only

(including

and

excluding

distribution)

compared

to

the

adjusted

operating

margins

of

the

peer

group

for

each

calendar

year

from

2014

to

2023.

In

their

review

of

the

comparative

data,

the

Board

Members

considered

the

limitations

of

the

comparative

data

given

that

peer

data

is

not

generally

public

and

the

calculation

of

profitability

is

subjective

and

affected

by

numerous

factors

(such

as

types

of

funds

a

peer

manages,

its

business

mix,

its

cost

of

capital,

the

numerous

assumptions

underlying

the

methodology

used

to

allocate

expenses

and

other

factors)

that

can

have

a

significant

impact

on

the

results.

44

Statement

Regarding

Basis

for

Approval

of

Investment

Advisory

Contract

(Unaudited)

(continued)

Aside

from

the

profitability

data,

the

Board

considered

that

NFAL

and

TAL

are

affiliates

of

Teachers

Insurance

and

Annuity

Association

of

America

(“TIAA”).

NFAL

is

a

subsidiary

of

Nuveen,

LLC,

the

investment

management

arm

of

TIAA,

and

TAL

is

an

indirect

wholly

owned

subsidiary

of

TIAA.

Accordingly,

the

Board

also

reviewed

a

balance

sheet

for

TIAA

reflecting

its

assets,

liabilities

and

capital

and

contingency

reserves

for

the

2023

and

2022

calendar

years

to

consider

the

financial

strength

of

TIAA.

The

Board

considered

the

benefit

of

an

investment

adviser

and

its

parent

with

significant

resources,

particularly

during

periods

of

market

volatility.

The

Board

also

considered

the

reinvestments

the

Adviser,

its

parent

and/or

other

affiliates

made

into

their

business

through,

among

other

things,

the

investment

of

seed

capital

in

certain

funds,

initiatives

in

international

expansion,

investments

in

infrastructure

and

continued

investments

in

enhancements

to

technological

capabilities.

The

Board

Members

considered

the

profitability

of

the

Sub-Adviser

from

its

relationships

with

the

respective

Nuveen

funds.

In

this

regard,

the

Board

Members

reviewed,

among

other

things,

the

Sub-Adviser’s

revenues,

expenses

and

net

revenue

margins

(pre-

and

after-tax)

for

its

advisory

activities

to

the

respective

Nuveen

funds

for

the

calendar

years

ended

December

31,

2023

and

December

31,

2022.

The

Board

Members

also

reviewed

a

profitability

analysis

reflecting

the

revenues,

expenses

and

revenue

margin

(pre-

and

after-tax)

grouped

by

similar

types

of

funds

(such

as

municipal,

taxable

fixed

income,

equity,

real

assets

and

index/asset

allocation)

for

the

Sub-Adviser

for

the

calendar

years

ending

December

31,

2023

and

December

31,

2022.

In

evaluating

the

reasonableness

of

the

compensation,

the

Board

Members

also

considered

the

indirect

benefits

NFAL

or

the

Sub-Adviser

received

that

were

directly

attributable

to

the

management

of

the

applicable

funds

as

discussed

in

further

detail

below.

Based

on

its

review,

the

Board

was

satisfied

that

each

Fund

Adviser’s

level

of

profitability

from

its

relationship

with

each

Nuveen

fund

was

not

unreasonable

over

various

time

frames

in

light

of

the

nature,

extent

and

quality

of

services

provided.

D.

Economies

of

Scale

and

Whether

Fee

Levels

Reflect

These

Economies

of

Scale

The

Board

considered

whether

there

have

been

economies

of

scale

with

respect

to

the

management

of

the

funds

in

the

fund

complex,

including

the

Funds,

whether

these

economies

of

scale

have

been

appropriately

shared

with

such

funds

and

whether

there

is

potential

for

realization

of

further

economies

of

scale.

Although

the

Board

considered

that

economies

of

scale

are

difficult

to

measure

with

any

precision

and

the

rates

at

which

certain

expenses

are

incurred

may

not

decline

with

a

rise

in

assets,

the

Board

considered

that

there

are

various

methods

that

may

be

employed

to

help

share

the

benefits

of

economies

of

scale,

including,

among

other

things,

through

the

use

of

breakpoints

in

the

management

fee

schedule,

fee

waivers

and/or

expense

limitations,

the

pricing

of

funds

at

scale

at

inception

and

investments

in

the

Adviser’s

business

which

can

enhance

the

services

provided

to

the

applicable

funds

for

the

fees

paid.

The

Board

considered

that

the

Adviser

has

generally

employed

one

or

more

of

these

various

methods

among

the

applicable

funds.

In

this

regard,

the

Board

considered,

as

noted

above,

that

the

management

fee

of

NFAL

generally

was

comprised

of

a

fund-level

component

and

a

complex-level

component

each

with

its

own

breakpoint

schedule,

subject

to

certain

exceptions.

With

this

structure,

the

Board

considered

that

the

complex-level

breakpoint

schedule

was

designed

to

deliver

the

benefits

of

economies

of

scale

to

shareholders

when

the

assets

of

eligible

funds

in

the

complex

pass

certain

thresholds

even

if

the

assets

of

a

particular

fund

are

unchanged

or

have

declined,

and

the

fund-level

breakpoint

schedules

were

designed

to

share

economies

of

scale

with

shareholders

if

the

particular

fund

grows.

The

Board

reviewed

the

fund-level

and

complex-level

fee

schedules.

As

summarized

above,

the

Board

approved

a

new

complex-level

breakpoint

schedule

which

would

simplify

and

reduce

the

complex-level

fee

rates

at

various

thresholds

and

expanded

the

eligible

funds

whose

assets

would

be

included

in

calculating

the

complex-level

fee,

effective

May

1,

2024.

Among

other

things,

the

assets

of

certain

TC

funds

advised

by

TAL

would

be

phased

into

the

calculation

of

the

complex-wide

assets

in

determining

the

complex-level

fee

over

a

ten-year

period.

The

Board

considered

the

cost

savings

and

additional

potential

sharing

of

economies

of

scale

as

a

result

of

the

reduced

complex-level

breakpoint

schedule

and

the

additional

assets

from

more

eligible

funds

in

calculating

the

assets

of

the

complex

for

determining

the

complex-level

fee

component.

The

Board

reviewed

the

projected

shareholder

savings

derived

from

such

modifications

over

a

ten-year

period

from

2024

to

2033.

The

Board

considered

management’s

representation

that

there

will

be

no

increase

to

any

fund’s

respective

advisory

agreement

fee

rate.

The

Board

also

considered

that

with

respect

to

Nuveen

closed-end

funds,

although

closed-end

funds

may

make

additional

share

offerings

from

time

to

time,

the

closed-end

funds

have

a

more

limited

ability

to

increase

their

assets

because

the

growth

of

their

assets

will

occur

primarily

from

the

appreciation

of

their

investment

portfolios.

The

Board

Members

also

considered

the

continued

reinvestment

in

Nuveen/TIAA’s

business

to

enhance

its

capabilities

and

services

to

the

benefit

of

its

various

clients.

The

Board

understood

that

many

of

these

investments

were

not

specific

to

individual

funds,

but

rather

incurred

across

a

variety

of

products

and

services

pursuant

to

which

the

family

of

funds

as

a

whole

may

benefit.

The

Board

further

considered

that

the

Adviser

and

its

affiliates

have

provided

certain

additional

services,

including,

but

not

limited

to,

services

required

by

new

regulations

and

regulatory

interpretations,

without

raising

advisory

fees

to

the

funds,

and

this

was

also

a

means

of

sharing

economies

of

scale

with

the

funds

and

their

shareholders.

The

Board

considered

the

Adviser’s

and/or

its

affiliates’

ongoing

efforts

to

streamline

the

product

line-up,

among

other

things,

to

create

more

scaled

funds

which

may

help

improve

both

expense

and

trading

economies.

Based

on

its

review,

the

Board

was

satisfied

that

the

current

fee

arrangements

together

with

the

reinvestment

in

management’s

business

appropriately

shared

any

economies

of

scale

with

shareholders.

E.

Indirect

Benefits

The

Board

Members

received

and

considered

information

regarding

various

indirect

benefits

the

respective

Fund

Adviser

or

its

affiliates

may

receive

as

a

result

of

their

relationship

with

the

funds

in

the

fund

complex,

including

the

Funds.

These

benefits

included,

among

other

things,

economies

of

scale

to

the

extent

the

Adviser

or

its

affiliates

share

investment

resources

and/or

personnel

with

other

clients

of

the

Adviser.

The

funds

may

also

be

45

used

as

investment

options

for

other

products

or

businesses

offered

by

the

Adviser

and/or

its

affiliates,

such

as

variable

products,

fund

of

funds

and

529

education

savings

plans,

and

affiliates

of

the

Adviser

may

serve

as

sub-advisers

to

various

funds

in

which

case

all

advisory

and

sub-advisory

fees

generated

by

such

funds

stay

within

Nuveen.

The

Board

considered

that

an

affiliate

of

the

Adviser

received

compensation

in

2023

for

serving

as

an

underwriter

on

shelf

offerings

of

existing

Nuveen

closed-end

funds

and

reviewed

the

amounts

paid

for

such

services

in

2023

and

2022.

In

addition,

the

Board

Members

considered

that

the

Adviser

and

Sub-Adviser

may

utilize

soft

dollar

brokerage

arrangements

attributable

to

the

respective

funds

to

obtain

research

and

other

services

for

any

or

all

of

their

clients,

although

the

Board

Members

also

considered

reimbursements

of

such

costs

by

the

Adviser

and/or

Sub-Adviser.

The

Adviser

and

its

affiliates

may

also

benefit

from

the

advisory

relationships

with

the

funds

in

the

fund

complex

to

the

extent

this

relationship

results

in

potential

investors

viewing

the

TIAA

group

of

companies

as

a

leading

retirement

plan

provider

in

the

academic

and

nonprofit

market

and

a

single

source

for

all

their

financial

service

needs.

The

Adviser

and/or

its

affiliates

may

further

benefit

to

the

extent

that

they

have

pricing

or

other

information

regarding

vendors

the

funds

utilize

in

establishing

arrangements

with

such

vendors

for

other

products.

Based

on

its

review,

the

Board

concluded

that

any

indirect

benefits

received

by

a

Fund

Adviser

as

a

result

of

its

relationship

with

the

Funds

were

reasonable

in

light

of

the

services

provided.

F.

Other

Considerations

The

Board

Members

did

not

identify

any

single

factor

discussed

previously

as

all-important

or

controlling.

The

Board

Members

concluded

that

the

terms

of

each

Advisory

Agreement

were

reasonable,

that

the

respective

Fund

Adviser’s

fees

were

reasonable

in

light

of

the

services

provided

to

each

Fund

and

that

the

Advisory

Agreements

be

renewed

for

an

additional

one-year

period.
