For

the

twelve

months

ended

March

31,

2023,

the

U.S.

bond

market

produced

mixed

results.

The

economy

stumbled

early,

but

it

quickly

recovered

despite

persistent

inflation

and

rising

interest

rates.

For

the

period,

two

major

fixed-income

sectors

recorded

gains,

while

others

lost

ground.

Four

of

the

eleven

TIAA-CREF

Fixed-Income

Funds

advanced,

and

the

Money

Market

Fund

posted

a

gain.

The

broad

U.S.

bond

market,

as

measured

by

the

Bloomberg

U.S.

Aggregate

Bond

Index,

returned

−4.8%

for

the

period.

Institutional

Class

returns

for

three

of

the

eleven

fixed-income

funds

outperformed

the

returns

of

their

respective

benchmarks.

Please

see

page

6

for

benchmark

definitions.

The

Money

Market

Fund

outperformed

the

iMoneyNet

Money

Fund

Averages™—All

Government.

Three

of

the

eight

remaining

funds—the

Core

Bond

Fund,

the

Inflation-Linked

Bond

Fund

and

the

Short-Term

Bond

Index

Fund—just

slightly

trailed

their

benchmarks.

Bond

performance

was

mixed

while

economy

rebounded

The

U.S.

economy

contracted

early

in

the

period

but

soon

began

to

grow

again,

in

large

part

due

to

an

exceptionally

strong

labor

market

and

solid

consumer

spending.

The

unemployment

rate

remained

at

near

50-year

lows.

Rising

prices

continued

to

be

problematic

for

the

economy.

However,

despite

continuing

to

rise,

the

annualized

rate

of

inflation

slowed

over

the

twelve

months.

The

Federal

Reserve

responded

aggressively

to

the

inflation

threat

by

raising

the

federal

funds

target

rate

multiple

times

during

the

period,

to

4.75%–5.00%.

Policymakers

indicated

that

further

action

was

possible.

Oil

prices

were

volatile

but

ended

the

period

lower.

Though

the

overall

fixed-income

market

produced

mixed

results,

each

of

its

major

sectors

lost

ground

during

the

first

half

of

the

period

before

advancing

in

the

final

six

months.

The

same

pattern

applied

to

the

Bloomberg

U.S.

Aggregate

Bond

Index.

For

the

entire

twelve-month

period,

municipal

bonds

produced

the

strongest

gain,

while

shorter-term

bonds

also

generated

a

positive

return.

U.S.

inflation-

protected

securities

and

high-yield

bonds

both

declined.

Four

TIAA-CREF

Fixed-Income

Funds

gained

in

an

uneven

period

Four

of

the

TIAA-CREF

Fixed-Income

Funds

registered

positive

results

for

the

twelve-

month

period.

Performance

for

the

Institutional

Class

ranged

from

−5.5%

for

the

Core

Impact

Bond

Fund

to

0.7%

for

the

Short-Term

Bond

Fund.

In

a

market

that

generally

favored

shorter-term

securities,

the

Money

Market

Fund

returned

2.6%,

beating

the

2.4%

return

of

the

iMoneyNet

Money

Fund

Averages™—All

Government.

The

Short-Term

Bond

Fund

rose

0.7%,

and

the

Short

Duration

Impact

Bond

Fund

advanced

0.4%,

both

outpacing

their

shared

benchmark,

the

Bloomberg

1–3

Year

Government/Credit

Bond

Index.

The

Short-Term

Bond

Index

Fund

modestly

trailed

the

same

benchmark

with

a

gain

of

0.2%.

The

5–15

Year

Laddered

Tax-Exempt

Bond

Fund

advanced

0.1%

but

lagged

the

Bloomberg

10-Year

Municipal

Bond

Index.

The

High-Yield

Fund

returned

−2.9%

but

outperformed

its

benchmark,

the

ICE

BofA

BB-B

U.S.

Cash

Pay

High

The

Inflation-Linked

Bond

Fund

returned

−3.0%,

slightly

lagging

the

Bloomberg

U.S.

Treasury

Inflation

Protected

Securities

(TIPS)

1–10

The

Green

Bond

Fund

returned

−4.7%

and

trailed

its

benchmark,

the

Bloomberg

MSCI

U.S.

Green

Bond

Index.

The

and

the

each

returned

and

The

returned

and

Keeping

long-term

goals

in

mind

Investing

for

the

future

is

a

long

journey,

with

many

twists

and

turns

along

the

way.

Financial

markets

are

affected

by

risks

and

opportunities

that

change

with

time,

and

sometimes

markets

respond

to

short-term

events

in

an

unpredictable

manner.

Today,

investors

are

focused

on

inflation,

rising

interest

rates

and

pressure

in

the

banking

industry.

In

the

future,

no

doubt

some

other

set

of

circumstances

will

take

center

stage.

Some

may

feel

a

temptation

to

react

to

these

shifts

as

they

develop.

But

it

has

long

been

our

opinion

that

investors

who

stick

with

a

thoughtful,

long-term

financial

plan

are

best

positioned

to

achieve

their

investment

goals.

We

believe

that

professionally

managed,

well-diversified

portfolios,

including

fixed-income

mutual

funds,

may

help

investors

do

just

that.

Of

course,

diversification

cannot

guarantee

against

market

losses.

Please

visit

TIAA.org

for

more

information

on

asset

class

performance.

If

you

have

further

questions

or

need

assistance

with

your

TIAA-CREF

fixed-income

portfolio,

we

suggest

you

contact

your

financial

advisor

or

call

a

TIAA

financial

consultant

at

800-842-2252.

We

would

be

happy

to

help

you.

Bonds

amid

rates,

concerns

Fixed-income

markets

generated

mixed

results

for

the

twelve-month

period

as

the

economy

got

off

to

a

slow

start

but

later

regained

its

footing.

The

uncertainty

in

both

the

markets

and

economy

stemmed

from

ongoing

concerns

over

inflation,

rising

interest

rates

and

the

possibility

of

a

recession.

While

price

increases

remained

worrisome

throughout

the

period,

the

rate

of

inflation

slowed.

The

Federal

Reserve

responded

to

inflation

concerns

by

raising

interest

rates

eight

times

over

the

twelve

months.

Meanwhile,

the

economy

generally

benefited

from

continued

strength

in

the

labor

market

and

solid

consumer

spending

levels.

Investment-grade

fixed-rate

bonds,

as

represented

by

returned

−4.8%

for

Among

market

segments,

municipal

bonds,

as

measured

by

the

All

major

segments

of

the

bond

market

declined

in

the

first

half

of

the

period

but

gained

ground

during

the

second

half.

Real

gross

domestic

product,

which

measures

the

of

produced

contracted

at

an

of

0.6%

during

the

of

2022.

But

GDP

soon

shifted

to

a

growth

pattern,

expanding

by

3.2%

in

the

third

quarter

and

2.6%

during

the

final

three

months

of

2022.

The

U.S.

unemployment

rate

declined

slightly

from

3.6%

in

April

2022

to

3.5%

in

March

2023,

hovering

at

historically

low

levels.

The

economy

added

more

than

four

million

new

jobs

over

the

twelve

months.

Core

inflation,

which

includes

all

items

except

food

and

energy,

rose

5.6%

for

the

twelve

months

ended

March

31,

2023.

The

period

began

with

an

annualized

inflation

rate

of

6.2%.

Oil

prices,

influenced

by

the

war

in

Ukraine

and

other

supply

constraints,

were

volatile

but

ended

lower.

The

price

of

West

Intermediate

crude

oil

began

the

period

at

$99

per

barrel,

peaked

at

nearly

$122

in

June

of

2022,

then

fell

just

below

$76

on

March

31,

2023.

The

broad

U.S.

stock

market,

as

measured

by

the

Russell

3000®

Index,

returned

−8.6%

for

the

twelve

months.

Stock

prices

declined

sharply

through

September

2022

but

recovered

over

the

final

six

months

of

the

period.

Yields

on

U.S.

Treasuries

of

all

maturities

rose

during

the

period,

with

increases

most

pronounced

among

shorter

maturities.

Fed

raised

rates

eight

times

The

Fed

acted

decisively

to

address

inflation

risks,

raising

the

federal

funds

target

rate

eight

times

during

the

period.

Those

moves

increased

the

key

short-term

interest-rate

measure

to

4.75%–5.00%,

and

policymakers

indicated

that

further

increases

may

be

necessary

to

return

inflation

rates

to

long-term

targets.

The

Fed

also

said

it

intended

to

continue

reducing

its

holdings

of

bonds

and

other

assets

purchased

previously

to

boost

the

economy.

Major

foreign

central

banks

also

raised

interest

rates

to

address

global

inflationary

pressure.

The

Central

Bank

increased

its

suite

of

interest

rates

from

near-zero

levels

to

3.00%–3.75%

in

U.S.

economy

expanded

in

2022,

despite

ongoing

concerns

regarding

inflation

and

rising

interest

rates.

Real

gross

domestic

product,

which

measures

the

value

of

all

goods

and

services

produced

in

the

United

States,

increased

at

an

annualized

rate

of

2.6%

during

the

fourth

quarter

of

last

year,

according

to

the

government’s

“third”

estimate.

The

unemployment

rate

remained

relatively

stable

and

settled

at

3.5%

in

March

2023.

Core

inflation,

which

measures

all

items

except

food

and

energy,

rose

5.6%

over

the

twelve

months

ended

March

2023.

Crude

oil

prices

were

volatile

but

declined

from

$99

to

$76

per

barrel

during

the

period.

The

Federal

Reserve

responded

to

the

economic

impact

of

higher

inflation

by

raising

the

federal

funds

target

rate

eight

times

during

the

twelve-month

period,

increasing

the

key

short-term

interest-rate

measure

to

4.75%–5.00%.

At

the

March

2023

meeting,

the

Fed

reiterated

that

policymakers

remained

“highly

attentive”

to

inflation

risks.

The

major

segments

of

the

fixed-income

market

posted

mixed

results

for

the

period,

dampened

by

a

rise

in

U.S.

Treasury

yields

across

all

maturities.

The

Bloomberg

U.S.

Aggregate

Bond

Index,

a

broad

measure

of

the

U.S.

investment-grade

fixed-

rate

bond

market,

declined

most.

High-yield

bonds

and

U.S.

Treasury

inflation-protected

securities

(TIPS)

recorded

smaller

setbacks.

Municipal

and

short-term

bonds

both

gained

ground.

All

sectors

in

the

benchmark

advanced

All

of

the

sectors

in

the

Bloomberg

U.S.

1–3

Year

Government/Credit

Bond

Index

posted

positive

returns

for

the

twelve

months.

Short-term

Treasuries,

by

far

the

benchmark’s

largest

sector

with

a

weighting

of

67.2%,

gained

0.2%.

Corporate

bonds—the

second-largest

sector

with

a

weighting

of

23.0%—was

the

index’s

best-performing

component

with

a

return

of

0.4%.

Government

credit

securities

and

government

agency

bonds

both

advanced

0.3%.

Fund

underperformed

its

benchmark

The

Fund

slightly

underperformed

its

benchmark

for

the

period.

The

Fund’s

return

includes

a

deduction

for

expenses,

while

the

benchmark’s

does

not.

The

Fund

seeks

to

maintain

the

overall

characteristics

of

its

benchmark.

The

Fund’s

managers

invest

in

the

same

sectors

that

are

included

in

the

benchmark

and

closely

match

the

benchmark’s

weightings

and

maturities.

At

times,

the

Fund

may

also

invest

in

securities

not

held

in

the

index,

but

which

have

investment

characteristics

that

are

similar

to

securities

held

in

the

index.

During

the

period,

this

portfolio

had

sector

returns

that

were

similar

to

its

benchmark,

enabling

it

to

resemble

the

index’s

performance.

Throughout

the

period,

the

Fund’s

managers

kept

the

Fund’s

duration—a

measure

of

its

sensitivity

to

interest-rate

changes—close

to

that

of

its

benchmark.

This

strategy

helped

the

Fund’s

risk

and

reward

characteristics

to

more

closely

resemble

those

of

its

benchmark.

Portfolio

Managers’

Comments

Higher

short-term

rates

benefited

money

market

investors

Although

inflation

and

higher

interest

rates

caused

concern

among

investors

during

the

period,

the

sharp

increase

in

short-

term

bond

yields

during

the

past

twelve

months

has

been

welcome

relief

for

money

market

investors,

leading

to

higher

returns.

While

it’s

uncertain

how

many

more

rate

hikes

the

Fed

has

in

store,

the

current

elevated

levels

of

short-term

yields

are

expected

to

remain

in

place

for

some

time.

Variable-rate

debt

securities,

which

made

up

nearly

30.0%

of

the

Fund’s

portfolio

at

period-end,

have

benefited

most

from

the

Fed’s

rate

increases.

The

“secured

overnight

financing

rate”

(SOFR)—a

key

indicator

of

short-term

government

money

market

rates—increased

dramatically

from

0.30%

on

April

1,

2022,

to

4.87%

on

March

31,

2023.

Fund

average

For

the

period,

the

return

of

the

Money

Market

Fund

surpassed

that

of

the

average.

In

pursuit

of

additional

yield,

management

continued

its

strategy

of

holding

higher-yielding

variable-rate

government

agency

paper,

which

benefited

the

Fund’s

performance.

As

of

March

Although

the

the

value

of

your

at

$1.00

it

do

so.

to

the Fund

at

The

gross

and

annual

operating

expenses

are

taken

from

the

Fund's

prospectus.

The

net

annual

operating

expenses

may

at

times

reflect

a

contractual

reimbursement

of

various

expenses.

The

expense

reimbursement

will

continue

through

at

least

July

31,

2023,

unless

changed

with

the

approval

of

the

Board

of

Trustees.

Teachers

Advisors,

and

its

affiliates,

have

agreed

to

voluntarily

waive

a

portion

of

the

expenses

of

the

Fund

to

the

extent

needed

to

maintain

a

non-negative

yield.

This

waiver

may

be

terminated

at

any

time.

Without

these

reimbursements,

expenses

would

be

higher

and

returns

lower.

Refer

to

the

Expense

Examples

40

All

shareholders

of

the

TIAA-CREF

Funds

incur

ongoing

costs,

including

management

fees

and

other

fund

expenses.

They

may

also

incur

transactional

costs

for

redemptions

or

account

maintenance

fees.

The

expense

examples

that

appear

in

this

report

are

intended

to

help

you

understand

your

ongoing

costs

only

(in

U.S.

dollars)

and

do

not

reflect

transactional

costs.

The

examples

are

designed

to

help

you

compare

these

ongoing

costs

with

the

ongoing

costs

of

investing

in

other

mutual

funds.

The

expenses

shown

do

not

include

account

maintenance

fees,

which

may

or

may

not

be

applicable,

as

described

in

the

prospectus.

If

such

fees

were

included,

your

total

costs

for

investing

in

the

funds

would

be

higher.

Note

also

that

shareholders

of

the

TIAA-CREF

Funds

do

not

incur

a

sales

charge

for

purchases,

reinvested

dividends

or

other

distributions.

The

examples

are

based

on

an

investment

of

$1,000

invested

at

the

beginning

of

the

six-month

period

and

held

for

the

entire

period

(

October

1,

2022

–

March

31,

2023

).

Actual

expenses

The

first

section

in

each

table

uses

the

Fund’s

actual

expenses

and

its

actual

rate

of

return.

You

may

use

the

information

in

this

section,

together

with

the

amount

you

invested,

to

estimate

the

expenses

that

you

paid

over

the

six-month

period.

Simply

divide

your

account

value

by

$1,000

(for

example,

an

$8,600

account

value

divided

by

$1,000

=

8.6),

then

multiply

the

result

by

the

number

in

the

first

line

under

the

heading

“Expenses

paid

during

period”

to

estimate

the

expenses

you

paid

during

the

six-month

period.

Some

funds

have

a

contractual

fee

reimbursement.

Had

these

not

been

in

effect,

fund

expenses

would

have

been

higher.

Hypothetical

example

for

comparison

purposes

The

second

section

in

each

table

shows

hypothetical

account

values

and

expenses

based

on

the

Fund’s

actual

expense

ratio

for

each

share

class

for

the

six-month

period

and

an

assumed

5%-per-year

rate

of

return

before

expenses.

This

was

not

the

share

class’

actual

return.

This

hypothetical

example

cannot

be

used

to

estimate

the

actual

expenses

you

paid

for

the

period,

but

rather

allows

you

to

compare

the

ongoing

costs

of

investing

in

the

Fund

with

the

costs

of

other

funds.

To

do

so,

compare

this

5%

hypothetical

example

with

the

5%

hypothetical

examples

that

appear

in

the

shareholder

reports

of

other

mutual

funds.

PCAOB.

We

conducted

our

audits

of

these

financial

statements

in

accordance

with

the

standards

of

the

PCAOB.

Those

standards

require

that

we

plan

and

perform

the

audit

to

obtain

reasonable

assurance

about

whether

the

financial

statements

are

free

of

material

misstatement,

whether

due

to

error

or

fraud.

Our

audits

included

performing

procedures

to

assess

the

risks

of

material

misstatement

of

the

financial

statements,

whether

due

to

error

or

fraud,

and

performing

procedures

that

respond

to

those

risks.

Such

procedures

included

examining,

on

a

test

basis,

evidence

regarding

the

amounts

and

disclosures

in

the

financial

statements.

Our

audits

also

included

evaluating

the

accounting

principles

used

and

significant

estimates

made

by

management,

as

well

as

evaluating

the

overall

presentation

of

the

financial

statements.

Our

procedures

included

confirmation

of

securities

owned

as

of

March

31,

2023

by

correspondence

with

the

custodian

and

brokers;

when

replies

were

not

received

from

brokers,

we

performed

other

auditing

procedures.

We

believe

that

our

audits

provide

a

reasonable

basis

for

our

opinions.

Note

2—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.

The Funds

are

investment

companies

and

follow

the

accounting

guidance

in

the

Financial

Accounting

Standards

Board

(“FASB”)

Accounting

Standards

Codification

946,

Services

—

Investment

Companies

. The net

asset

value (“NAV”)

for

financial

reporting

purposes

may

differ

from

the NAV

for

processing

transactions.

The NAV

for

financial

reporting

purposes

includes

security

and shareholder

transactions

through

the

date

of

the

report.

Total

return

is

computed

based

on

the NAV

used

for

processing

transactions.

The

following

is

a

summary

of

the

significant

accounting

policies

consistently

followed

by

the

Funds.

Investments

and

Investment

Income:

Securities

transactions

are

accounted

for

as

of

the

trade

date

for

financial

reporting

purposes.

Interest

income

is

recorded

on

an

accrual

basis

and

includes

accretion

of

discounts

and

amortization

of

premiums.

Dividend

income

is

recorded

on

the

ex-dividend

date.

Foreign

dividend

income

is

recorded

on

the

ex-dividend

date

or

as

soon

as

possible

after

the Funds

determine

the

existence

of

a

dividend

declaration.

Securities

lending

income

is

comprised

of

fees

earned

from

borrowers

and

income

earned on

cash

collateral

investments. Realized

gains

and

losses

on

securities

transactions

are

based

upon

the

specific

identification

method.

Distributions

received

on

securities

that

represent

a

return

of

capital

or

capital

gains

are

recorded

as

a

reduction

of

cost

of

investments

and/or

as

a

realized

gain.

The

Funds estimate

the

components

of

distributions

received

that

may

be

considered

return

of

capital

distributions

or

capital

gain

distributions.

Multiclass

Operations

and

Allocations:

Income, expenses,

realized

gains

and

losses

and

unrealized

appreciation

and

depreciation

of

a

Fund

are

allocated

on

a

pro

rata

basis

to

each

class

of

shares,

except

for

service

agreement

fees,

distribution

fees

and

transfer

agency

fees

and

expenses, which

are

unique

to

each

class

of

shares.

Most

expenses

of

the

Trust

can

be

directly

attributed

to

a

Fund.

Expenses

that

cannot

be

directly

attributed

are

allocated

to

each

Fund

in

the

Trust

based

upon

the

average

net

assets

of

each

Fund.

Distributions

to

Shareholders:

Distributions

to

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.

Foreign

Currency

Transactions

and

Translation:

The

books

and

records

of

the

Funds

are

maintained

in

U.S.

dollars.

Assets,

including

investments,

and

liabilities

denominated

in

foreign

currencies

are

translated

into

U.S.

dollars

at

the

end

of

each

day.

Purchases

and

sales

of

income,

and

expenses

are

translated

into

U.S.

dollars

at

the

prevailing

exchange

rate

on

the

respective

dates

of

the

transactions.

are

recognized

as

a

component

of

“Net

change

in

unrealized

appreciation

(depreciation)”

on

the

Statement

of

Operations,

when

applicable.

The

unrealized

gains

and

losses

resulting

from

changes

in

foreign

are

recognized

as

a

component

of

the

respective

derivative’s

related “Net

change

in

unrealized

appreciation

(depreciation)”

on

the

Statement

of

Operations,

when

applicable. 

Foreign

Taxes:

The Funds

may

be

subject

to

foreign

taxes

on

income,

gains

on

investments

or

currency

repatriation,

a

portion

of

which

may

be

recoverable.

The Funds

will

accrue

such

taxes

and

recoveries

as

applicable,

based

upon

the

current

interpretation

of

tax

rules

and

regulations

that

exist

in

the

markets

in

which

the Funds

invest.

Trustee

Compensation:

The

Funds pay

the

members

of

the

Board

of

Trustees

(“Board”),

all

of

whom

are

independent,

certain

remuneration

for

their

services,

plus

travel

and

other

expenses.

Trustees

may

elect

to

participate

in

a

deferred

compensation

plan

and

defer

all

or

a

portion

of

their

compensation.

In

addition,

trustees

participate

in

a

long-term

compensation

plan.

Amounts

deferred

are

retained

by

the

Funds

until

paid.

Amounts

payable

to

the

trustees

for

compensation

are

included

separately

in the

accompanying

Statements

of

Assets

and

Liabilities.

Trustees’

fees,

including

any

deferred

and

long-term

compensation

incurred,

are

reflected

in

the

Statement

of

Operations.

Indemnification:

 Under

the

Trust's

organizational

documents,

its

officers

and

trustees

are

indemnified

against

certain

liabilities

arising

out

of

the

performance

of

their

duties

to

the

Trust.

In

addition,

in

the

normal

course

of

business,

the

Trust

enters

into

contracts

that

provide

general

indemnifications

to

other

parties.

The

Trust's

maximum

exposure

under

these

arrangements

is

unknown

as

this

would

involve

future

claims

that

may

be

made

against

the

Trust

that

have

not

yet

occurred.

However,

the

Trust

has

not

had

prior

claims

or

losses

pursuant

to

these

contracts

and

expects

the

risk

of

loss

to

be

remote.

New

Accounting

Pronouncement:

In

March

2020,

FASB

issued

Accounting

Standards

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

changes

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

Fund may

elect

to

apply

the

amendments

as

of

March

12,

2020

through

December

31,

2022.

In

December

2022,

FASB

deferred

ASU

2022-04

and

issued

ASU

2022-06,

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

820,

Fair

Value

Measurement

(“Topic

820”).

The

amendments

in

ASU

2022-03

affect

all

entities

that

have

investments

in

equity

securities

measured

at

fair

value

that

are

subject

to

a

contractual

sale

restriction.

ASU

2022-03

(1)

clarifies

the

guidance

in

Topic

820,

when

measuring

the

fair

value

of

an

equity

security

subject

to

contractual

restrictions

that

prohibit

the

sale

of

an

equity

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

fair

value

in

accordance

with

Topic

820.

For

public

business

entities,

the

amendments

in

ASU

2022-03

are

effective

for

fiscal

years

beginning

after

December

15,

2023,

and

interim

periods

within

those

fiscal

years.

For

all

other

entities,

the

amendments

are

effective

for

fiscal

years

beginning

after

December

15,

2024,

and

interim

periods

within

those

fiscal

years.

Early

adoption

is

permitted

for

both

interim

and

annual

financial

statements

that

have

not

yet

been

issued

or

made

available

for

issuance.

Management

is

currently

assessing

the

impact

of

these

provisions

on

the

Funds' financial

statements.

New

Rule

Issuance:

 A

new

rule

adopted

by

the

SEC

governing

fund

valuation

practices,

Rule

2a-5

under

the

1940

Act,

has

established

requirements

for

determining

fair

value

in

good

faith

for

purposes

of

the

1940

Act.

Rule

2a-5

permits

fund

boards

to

designate

certain

parties

to

perform

fair

value

determinations,

subject

to

board

oversight

and

certain

other

conditions.

Rule

2a-5

also

defines

when

market

quotations

are

"readily

available"

for

purposes

of

Section

2(a)(41)

of

the

1940

Act,

which

requires

a

fund

to

fair

value

a

security

when

market

quotations

are

not

readily

available.

Separately,

new

SEC

Rule

31a-4

under

the

1940

Act

sets

forth

the

recordkeeping

requirements

associated

with

fair

value

determinations.

The Funds

adopted

a

valuation

policy

conforming

to

the

new

rules,

effective

September

1,

2022,

and

there

was

no

material

impact

to

the

Funds.

Note

3—Valuation

of

Investments

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

that

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:

Debt

Securities:

Prices

of

fixed-income

securities

are

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.

Exchange-Traded

Equity

Securities,

Common

and

Preferred

Stock:

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. 

The

Money

Market  Fund:

The

Money

Market

Fund’s

portfolio

securities

are

valued

on

an

amortized

cost

basis.

Money

Market

investments

are

generally

classified

as

Level

2.

Investments

in

Registered

Investment

Companies:

Investments

in

investment

companies

are

valued

at

their

respective NAVs

or

share

price

on

the

valuation

date

and

are

generally

classified

as Level

1.

Repurchase

Agreements:

Repurchase

agreements

are

valued

at

contract

amount

plus

accrued

interest,

which

approximates

market

value.

These

securities

are

generally

classified

as

Level

2.

Futures

Contracts:

Futures

contracts

are

valued

using

the

closing

settlement

price

or,

in

the

absence

of

such

a

price,

the

last

traded

price and

are

generally

classified

as

Level

1.

Forward

Foreign

Currency

Contracts:

Forward

foreign

currency

contracts

are

valued

using

the

prevailing

forward

exchange

rate

which

is

derived

from

quotes

provided

by

the

pricing

service

using

the

procedures

approved

by

the

Adviser,

subject

to

the

oversight

of

the

Board,

and

are

classified

as

Level

2.

405

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:

Mortgage

Dollar

Roll

Transactions:

Some

of

the Funds may

enter

into

mortgage

dollar

rolls

in

which a

Fund

sells

mortgage

securities

for

delivery

in

the

current

month,

realizing

a

gain

(loss),

and

simultaneously

contracts

to

repurchase

similar

securities

on

a

specified

future

date.

During

the

roll

period,

a

Fund forgoes

principal

and

interest

paid

on

the

securities.

The Fund is

compensated

by

the

interest

earned

on

the

cash

proceeds

of

the

initial

sale

and

by

the

lower

repurchase

price

at

the

future

date.

The

difference

between

the

sales

proceeds

and

the

repurchase

price

is

recorded

as

a

realized

gain

or

loss.

Repurchase

Agreements:

In

connection

with

transactions

in

repurchase

agreements,

it

is

the Fund’s policy

that

its

custodian

take

possession

of

the

underlying

collateral

securities,

the

fair

value

of

which

exceeds

the

principal

amount

of

the

repurchase

transaction,

including

accrued

interest,

at

all

times.

If

the

counterparty

defaults,

and

the

fair

value

of

the

collateral

declines,

realization

of

the

collateral

may

be

delayed

or

limited.

Restricted

Securities:

Restricted

securities

held

by

the

Funds,

if

any,

may

not

be

sold

except

in

exempt

transactions

or

in

a

public

offering

registered

under

the

Securities

Act

of

1933,

as

amended.

The

risk

of

investing

in

such

securities

is

generally

greater

than

the

risk

of

investing

in

securities

that

are

widely

held

and

publicly

traded.

Securities

Lending:

Certain Funds

may

lend

their

securities

to

qualified

institutional

borrowers

to

earn

additional

income.

A

Fund receives

collateral

(in

the

form

of

cash,

Treasury

securities

or

other

collateral

permitted

by

applicable

law)

against

the

loaned

securities

and

maintains

collateral

in

an

amount

not

less

than

100%

of

the

market

value

of

loaned

securities

during

the

period

of

the

loan;

any

additional

collateral

required

due

to

changes

in

security

values

is

delivered

to

the Fund

the

next

business

day.

Cash

collateral

received

by the

Fund will

generally

be

invested

in

high-quality

short-term

instruments

or

in

one

or

more

funds

maintained

by

the

securities

lending

agent

(“Agent”)

for

the

purpose

of

investing

cash

collateral.

at

the

time

of

a

default

by

a

borrower

some

or

all

of

the

securities

have

not

As

the

end

of

the

reporting

period,

the

total

of

securities

on

loan

and

the

total

value

of

collateral

received

were

as

follows:

Securities

Purchased

on

a

When-Issued

or

Delayed-Delivery

Basis:

The Funds

may

purchase

securities

on

a

when-issued

or

delayed-

delivery

basis.

Securities

purchased

or

sold

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.

The

Funds have

segregated

securities

in

their

portfolios

with

a

current

value

at

least

equal

to

the

amount

of

the

when-issued/delayed

delivery

purchase

commitments.

Treasury

Inflation-Protected

Securities:

The

Funds (other

than

the

Money

Market

Fund)

may

invest

in

Treasury

Inflation-Protected

Securities,

specially

structured

bonds

in

which

the

principal

amount

is

adjusted

periodically

to

keep

pace

with

inflation,

as

measured

by

the

U.S.

Consumer

Price

Index.

The

adjustments

for

interest

income

due

to

inflation

or

deflation

are

reflected

in

interest

income

in

the

Statement

of

Operations.

Unfunded

Commitments:

Pursuant

to

the

terms

of

certain

loan

agreements,

the

Funds may

have

unfunded

loan

commitments.

Unfunded

commitments

are

contractual

obligations

pursuant

to

which

a

Fund agrees

to

invest

in

a

loan

at

a

future

date.

Each

Fund segregates

short-term

securities

or

cash

having

an

aggregate

value

at

least

equal

to

the

amount

of

the

unfunded

loan

commitments.

If

a

Fund has

unfunded

commitments

at

the

end

of

the

reporting

period,

such

amounts

are

recognized

on

the

Statement

of

Assets

and

Liabilities

as

“Payable

for

unfunded

commitments.”

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.

5—Derivative

Investments

Each Fund

(other

than

the

Money

Market

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.

At

the

end

of

the

reporting

period,

the

following Funds

have

invested

in

derivative

contracts

which

are

reflected

in

the

Statement

of

Assets

and

Liabilities

as

follows:

During

the

current

fiscal

period,

the

effect

of

derivative

contracts

on

the Funds'

Statement

of

Operations

was

as

follows:

Futures

Contracts:

 Certain

Funds

are

subject

to

interest

rate

and

foreign

exchange

risk

in

the

normal

course

of

pursuing

their

investment

objectives.

The Funds

use

futures

contracts

to

manage

exposure

to

the

bond

and

foreign

exchange

markets

and

to

fluctuations

in

interest

and

foreign

exchange

rates and

for

cash

management

purposes

to

remain

highly

invested

in

these

markets

while

minimizing

transaction

costs.

A

futures

contract

is

an

agreement

between

two

parties

to

buy

and

sell

a

financial

instrument

for

a

set

price

on

a

future

date.

Upon

execution

of

a

futures

contract,

the

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.

Securities

During

the

period

the

futures

contract

is

open,

changes

in

the

market

value

of

the

contract

are

recognized

as

an

unrealized

gain

or

loss

by

“marking-to-market”

on

a

daily

basis.

The

Fund

and

the

clearing

broker

are

obligated

to

settle

monies

on

a

daily

basis

representing

the

changes

in

the

value

of

the

contracts.

These

daily

cash

settlements

are

known

as

“variation

margin”

which are

recognized

on

the

Statement

of

Assets

and

Liabilities

as

a

receivable

or

payable

for

variation

margin

on

futures

contracts.

When

the

contract

is

closed

or

expired,

the

Fund

records

a

realized

gain

or

loss

equal

to

the

difference

between

the

value

of

the

contract

on

the

closing

and

value

of

the

when

originally

entered

(depreciation)

on

contracts

held

during

the

period

is

included

on

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

securities

or

indices.

The

average

notional

amount

of

futures

contracts

outstanding

during

the

period was

as

follows:

Forward

Foreign

Currency

Contracts:

Certain Funds

may

use

forward

foreign

contracts

("forward

to

currency

risk

and

to

facilitate

transactions

in

securities

denominated in

foreign

currencies

in

the

normal

course

of

pursuing

their

investment

objectives.

A

forward

contract

is

an

agreement

between

two

parties

to

purchase

or

sell

a

specified

quantity

of

a

currency

at

or

before

a

specified

date

in

the

future

at

a

specified

price.

Non-deliverable

forward

foreign

currency

exchange

contracts

are

settled

with

the

counterparty

in

cash

without

the

delivery

of

foreign

currency.

Forward

contracts

are

typically

traded

in

the

over-the-counter

(“OTC”)

markets

and

all

details

of

the

contract

are

negotiated

between

the

counterparties

to

the

agreement.

Forward

contracts

are

marked-to-market

daily

and

any

resulting

unrealized

gains

or

losses

are

reflected

as

appreciation

or

depreciation

on

the

Statement

of

Assets

and

Liabilities.

The Funds

realize

gains

and

losses

at

the

time

the

forward

contracts

are

closed

and

are

included

on

the

Statement

of

Operations.

Risks

may

arise

upon

entering

into

forward

contracts

from

unanticipated

movements

in

the

value

of

a

foreign

currency

relative

to

the

U.S.

dollar;

and

that

losses

may

exceed

amounts

recognized

on

the

The

The

invest

in

credit

to

hedge

or

manage

the

risks

associated

with

the

Funds

and/or

to

facilitate

the

implementation

of

portfolio

strategies

to

seek

to

increase

the

Credit

contracts

involve

one

party

making

a

stream

of

payments

(buyer

to

another

party

(seller

of

in

for

the

right

to

receive

a

if/when

there

is

a

event

by

a

third

party.

Credit

events

are

agreement

but

may

include

bankruptcy,

protection

in

a

credit

default

swap

upon

occurrence

of

a

specific

credit

event

with

respect

to

the

the

Fund will

either

(i)

receive

that

security,

or

an

equivalent

amount

of

cash,

from

the

counterparty

Note

7—Income

Tax

Information

Each

Fund

is

a

separate

taxpayer

for

federal

income

tax

purposes.

Each

Fund

intends

to

distribute

substantially

all

of

its

net

investment

income

and

net

capital

gains

to

shareholders

and

otherwise

comply

with

the

requirements

of

Subchapter

M

of

the

Internal

Revenue

Code

applicable

to

regulated

investment

companies.

Therefore,

no

federal

income

tax

provision

is

required.

The

5-15

Year

Laddered

Tax-Exempt

Bond

Fund

intends

to

satisfy

conditions

that

will

enable

interest

from

municipal

securities,

which

is

exempt

from

regular

federal

income

tax,

to

retain

such

tax-exempt

status

when

distributed

to

shareholders

of

the

Fund.

Net

realized

capital

gains

and

ordinary

income

distributions

paid

by

the

Fund

are

subject

to

federal

taxation. 

Each

Fund

files

income

tax

returns

in

U.S.

federal

and

applicable

state

and

local

jurisdictions.

A

Fund’s

federal

income

tax

returns

are

generally

subject

to

examination

for

a

period

of

three

fiscal

years

after

being

filed.

State

and

local

tax

returns

may

be

subject

to

examination

for

an

additional

period

of

time

depending

on

the

jurisdiction.

Management

has

analyzed

each

Fund’s

tax

positions

taken

for

all

open

tax

years

and

has

concluded

that

no

provision

for

income

tax

is

required

in

the

Fund’s

financial

statements.

Differences

between

This

Fund

is

subject

to

a

breakpoint

schedule

on

its

investment

management

fee,

which

reduces

this

fee

as

the

Fund’s

net

assets

increase.

‡

Maximum

expense

amounts

reflect

all

expenses

excluding

interest,

taxes,

brokerage

commissions

or

other

transactional

expenses,

Acquired

and

expenses.

The

reimbursement

can

only

be

with

the

approval

of

the

Board.

A

registered

separate

account

of

TIAA

(collectively

“TIAA

Access”)

has

various

sub-accounts

that

invest

in

the

Funds,

and

certain

funds

within

the

Trust

also

make

investments

in

the

Funds.

The

following

is

the

percentage

of

the

Funds'

shares

owned

by

affiliates

as

of

the

end

of

the

reporting

period:

Note

9—Inter-Fund

Lending

Program

Pursuant

to

an

exemptive

order

issued

by

the

SEC,

the

Funds may

participate

in

an

inter-fund

lending

program.

This

program

allows

the

Funds to

lend

cash

to

and/or

borrow

cash

from

certain

other

affiliated

Funds for

temporary

purposes,

(e.g.,

to

satisfy

redemption

requests

or

to

cover

unanticipated

cash

shortfalls).

The

program

is

subject

to

a

number

of

conditions,

including

the

requirement

that

no

Fund may

borrow

or

lend

money

under

the

program

unless

it

receives

a

more

favorable

interest

rate

than

is

available

from

a

bank

or

other

financial

institution

for

a

comparable

transaction.

In

addition,

a

Fund may

participate

in

the

program

only

if

its

participation

is

consistent

with

the

Fund’s investment

policies

and

limitations

and

authorized

by

its

portfolio

manager(s).

During the current

reporting

period,

there

were

no

inter-fund

borrowing

or

lending

transactions. 

Note

10—Line

of

Credit

The Funds

(other

than

Money

Market

Fund)

participate

in

a

$1

billion

unsecured

revolving

credit

facility

that

can

be

used

for

temporary

purposes,

including,

without

limitation,

the

funding

of

shareholder

redemptions.

The

current

facility

was

entered

into

on

June

14,

2022

expiring

on

June

13,

2023,

replacing

the

previous facility,

which

expired

June

2022.

Certain

affiliated

accounts

and

mutual

funds,

each

of

which

is

managed

by the

Adviser,

or

an

affiliate

of

the

Adviser, also

participate

in

this

facility.

An

annual

commitment

fee

for

the

credit

facility

is

borne

by

the

participating

accounts

and

mutual

funds

on

a

pro

rata

basis.

Interest

associated

with

any

borrowing

under

the

facility

is

charged

to

the

borrowing

accounts

or

mutual

funds

at

a

specified

rate

of

interest.

The Funds are

not

liable

for

borrowings

under

the

facility

by

other

affiliated

accounts

or

mutual

funds.

There

were

no

borrowings

under

this

credit

facility

by

the

Funds during

the

current fiscal

period.

Note

11—Subsequent

Events

The

Adviser

has

agreed

to

implement

a voluntary

waiver

reducing

the

management

fee

breakpoint

schedule

for the Inflation-Linked

Bond

Fund

for

one

year

effective

May

1,

2023.

This

waiver is

voluntary

in

nature

and

can

be

discontinued

at

any

time

without

prior

notice

to

shareholders

upon

Board

approval.

During

this

one-year

period

the

paid

to

the

Adviser

is

Renewal

of

The

Board

of

Trustees

(the

or

the

of

the

TIAA-CREF

Funds

(the

determines

whether

to

initially

approve

and

periodically

renew

the

management

agreement

(the

“Agreement”)

between

Teachers

Advisors,

LLC

(“Advisors”)

and

the

Trust

on

behalf

of

each

series

of

the

Trust.

Under

the

Agreement,

Advisors

is

responsible

for

providing

investment

advisory

services

to

each

series

of

the

Trust

and

overseeing

the

everyday

operations

and

other

service

providers

of

the

Trust.

Below

is

a

summary

of

the

process

the

Board

undertook

related

to

its

most

recent

renewal

of

the

Agreement

with

respect

to

each

series

covered

by

this

Report

(the

“Funds”).

Section

15(c)

of

the

Investment

Company

Act

of

1940,

as

amended

(the

“1940

Act”),

requires

that,

after

an

initial

period

of

up

to

two

years,

the

Agreement

for

each

Fund

will

remain

in

effect

only

if

the

Board,

including

a

majority

of

those

Trustees

who

have

no

direct

or

indirect

interest

in

the

Agreement,

and

who

are

independent

Trustees

because

they

are

not

“interested

persons”

of

the

Trust,

as

that

term

is

defined

in

the

1940

Act,

annually

renews

the

Agreement.

None

of

the

Trustees

is

an

interested

person

of

the

Trust

under

the

1940

Act.

Rather,

they

are

all

deemed

to

be

independent

Trustees.

Overview

of

the

Renewal

Process

The

Board

held

an

in-person

meeting

on

March

10,

2023,

in

order

to

consider

the

annual

renewal

of

the

Agreement

with

respect

to

each

applicable

Fund

using

the

process

established

by

the

Board

described

further

below.

As

part

of

the

Board’s

established

process,

the

Board

delegated

certain

tasks

to

its

Operations

Committee.

Among

these

tasks,

the

Operations

Committee

or

certain

of

its

designated

members

worked

with

Advisors,

other

Board

members

and

legal

counsel

to

the

Trustees

to

develop

guidance

and

specific

requests

relating

to

the

types

of

information

to

be

provided

to

the

Board

in

connection

with

the

proposed

contract

renewals.

Among

other

matters,

the

Operations

Committee

or

certain

of

its

designated

members,

following

consultations

with

representatives

of

Advisors,

other

Board

members,

legal

counsel

to

the

Trustees

and

legal

counsel

to

Advisors

and

the

Trust,

confirmed

or

established

certain

guidance

regarding

the

preparation

of

reports

to

be

provided

to

the

Board

with

respect

to

each

Fund

by

the

Board

Reporting

and

Compliance

unit

of

Broadridge

Financial

Solutions,

Inc.

(“Broadridge”),

using

data

from

Lipper,

Inc.,

an

independent

provider

of

investment

company

data.

The

Operations

Committee

considered

that

Broadridge

is

widely

recognized

as

a

leading

provider

of

comparative

analyses

used

by

independent

directors

and

trustees

of

investment

companies

during

their

advisory

contract

review

processes.

Based

on

guidance

provided

by

the

Operations

Committee

or

certain

of

its

designated

members,

on

behalf

of

the

Board,

Broadridge

produced,

among

other

information,

comparative

performance

and

expense

data

for

each

Fund,

including

data

relating

to

each

Fund’s

management

fee

rate,

total

expense

ratio,

short-term

and

long-term

investment

performance

and

portfolio

turnover

rate

(as

applicable).

Broadridge

compared

this

data,

as

relevant,

for

each

Fund

against

a

universe

of

investment

companies

and

against

a

more

selective

peer

group

of

mutual

funds

with

similar

investment

objectives

and

strategies,

each

of

which

was

selected

by

Broadridge,

and

also

compared

the

performance

of

each

Fund

against

one

or

more

appropriate

broad-based

indices.

In

each

case,

Broadridge

summarized,

and

the

Board

considered,

the

methodologies

Broadridge

employed

to

provide

the

data

contained

in

its

reports.

In

addition,

Broadridge

represented

to

the

Board

that

its

reports

were

designed

specifically

to

provide

the

Board

with

the

fee,

expense

and

performance

information

that

is

necessary

to

help

the

Board

satisfy

its

duties

under

Section

15(c)

of

the

1940

Act.

Broadridge

also

represented

that

the

purpose

of

its

reports

is

to

provide

an

objective

view

of

each

Fund’s

relative

position

regarding

the

level

of

fees,

expenses

and

performance

against

a

competitive

peer

group

and

universe

(as

applicable)

selected

by

Broadridge

(and

not

Advisors

or

the

Board).

The

Board

considered

the

propriety

of

each

Fund’s

applicable

peer

group

as

selected

by

Broadridge

and

use

of

the

Institutional

Class

as

the

base

class

for

comparison

purposes.

Among

other

matters,

the

Board

also

considered

information

from

Advisors

to

facilitate

the

Trustees’

evaluation

of

the

reasonableness

of

any

profits

earned

by

Advisors

with

respect

to

its

services

to

each

Fund

pursuant

to

the

Agreement.

427

Legal

counsel

for

the

Trustees

also

requested

on

behalf

of

the

Board,

and

Advisors

provided,

information

that

was

designed

to

assist

the

Board

in

its

consideration

of

whether

to

renew

the

Agreement

for

each

Fund.

In

addition

to

the

data

provided

by

Broadridge

as

described

above,

the

information

that

was

provided

for

consideration

included,

but

was

not

limited

to,

the

following:

(1)

further

information

relating

to

each

Fund’s

investment

performance

and

a

narrative

analysis

of

the

performance

of

each

Fund

that

had

underperformed

certain

Board-specified

criteria,

together

with

an

explanation

of

any

events

that

had

a

material

impact

on

the

Fund’s

performance

during

that

period;

(2)

a

description

of

any

fee

waiver

or

expense

reimbursement

arrangements

that

were

proposed

or

were

in

place

during

the

prior

year

and

the

extent

to

which

such

arrangements

would

be

continued

or

modified

in

the

coming

year;

(3)

a

comparison

of

each

Fund’s

management

fee

rate

and

performance

to

other

accounts

with

comparable

strategies

managed

by

Advisors

or

certain

of

its

affiliates;

(4)

any

“fall-out”

benefits

that

accrued

or

were

identified

as

reasonably

likely

to

accrue

to

Advisors

or

its

affiliates

due

to

their

relationship

with

the

Funds

in

addition

to

the

Funds’

direct

fee

payments

to

Advisors

pursuant

to

the

Agreement;

(5)

information

regarding

Advisors’

financial

resources,

senior

professional

personnel,

overall

staffing

levels,

portfolio

manager

compensation

arrangements,

capacity

to

manage

the

Funds

at

current

and

foreseeable

asset

levels,

insurance

coverage,

portfolio

trading

and

best

execution

practices,

and

any

actual

and

potential

conflicts

of

interest

identified

by

Advisors

in

connection

with

rendering

services

to

the

Funds;

(6)

information

as

to

any

profits

earned

by

Advisors

in

connection

with

its

services

pursuant

to

the

Agreement;

(7)

a

copy

of

the

Agreement

and

certain

related

agreements

between

the

Funds

and

affiliates

of

Advisors;

(8)

a

copy

of

Advisors’

Form

ADV

as

filed

with

the

SEC

(which

was

presented

only

to

legal

counsel

for

the

Trustees);

and

(9)

draft

narrative

explanations

to

be

included

in

the

shareholder

reports

of

reasons

why

the

Board

should

renew

the

Agreement.

The

Trustees

were

also

provided

with

performance

ratings

of

Morningstar,

Inc.

(“Morningstar”),

which

is

a

widely

recognized

mutual

fund

ranking

service.

The

Board

also

considered

information

concerning

the

extent

to

which

Advisors

currently

waives

the

management

fee

and

other

expenses

for

Class

W

shares

of

certain

of

the

Funds

which

are

paid

instead

by

funds

of

funds

that

invest

in

Class

W

shares,

including

an

annual

certification

from

Advisors

that

the

waiver

does

not

and

will

not

result

in

any

cross-subsidization

of

Class

W

shares

by

the

Funds’

other

share

classes.

On

March

2,

2023,

the

Board

held

a

virtual

meeting

via

videoconference

with

legal

counsel

to

the

Trustees

to

discuss

Advisors’

materials,

which

led

to

the

Trustees

providing

additional

questions

to,

and

requesting

additional

information

from,

Advisors.

Subsequently,

at

the

March

10,

2023

meeting,

the

Trustees

were

given

the

opportunity

to,

and

did,

ask

additional

questions

and

they

discussed

responses

from

Advisors

to

the

Board’s

follow-up

questions

and

requests

presented

by

the

Board

after

its

initial

review

of

the

information

described

above.

In

considering

whether

to

renew

the

Agreement

with

respect

to

each

Fund,

the

Board

considered

various

factors,

including:

(1)

the

nature,

extent

and

quality

of

services

provided

or

to

be

provided

by

Advisors

to

the

Fund;

(2)

the

Fund’s

investment

performance;

(3)

the

costs

of

the

services

provided

to

the

Fund

and

the

profits

realized

or

potential

profits

to

be

realized

(if

any)

by

Advisors

and

its

affiliates

from

their

relationship

with

the

Fund;

(4)

fees

charged

to

comparable

mutual

funds

by

other

advisers;

(5)

the

extent

to

which

economies

of

scale

have

been

realized

or

are

anticipated

to

be

realized

as

the

Fund

grows;

(6)

how

such

economies

of

scale

are

shared

with

the

Fund

for

the

benefit

of

its

investors,

such

as,

if

applicable,

through

management

fee

breakpoints;

(7)

comparisons,

if

applicable,

of

the

services

provided

by

Advisors

to,

and

the

fee

rates

and

performance

of,

the

Fund

to

other

clients

to

whom

Advisors

provides

comparable

services;

and

(8)

any

other

benefits

identified

by

Advisors

derived

or

anticipated

to

be

derived

by

Advisors

or

its

affiliates

from

their

relationship

with

the

Fund.

As

a

general

matter,

the

Board

considered

these

factors,

and

any

other

factors

deemed

relevant

by

the

Trustees,

in

their

totality,

and

no

single

factor

was

identified

as

being

the

determining

factor

in

deciding

whether

to

renew

the

Agreement.

In

addition

to

the

March

10,

2023

meeting

that

included

Advisors’

personnel,

the

Trustees

met

in

executive

sessions,

at

which

no

representatives

of

Advisors

were

present,

to

discuss

the

proposed

renewal

of

the

Agreement

for

each

Fund.

The

Board

also

received

and

considered

information

from

its

legal

counsel

as

to

certain

relevant

guidance

that

relates

to

the

renewal

process

under

Section

15(c)

of

the

1940

Act

and

certain

other

legal

authorities.

While

the

contract

renewal

process

included

a

series

of

discussions

and

meetings

leading

up

to

the

March

10,

2023

meeting,

the

oversight

and

evaluation

of

Advisors’

services

to

the

Funds

by

the

Board

and

its

Committees

is

an

ongoing

process.

The

Board,

as

well

as

its

Committees,

considered

reports

on

various

investment

and

operational

topics

that

had

been

identified

by

the

Board

or

its

Committees

for

review

in

the

year

since

the

last

annual

renewal

process.

Further,

at

their

regularly

scheduled

meetings,

the

Board

and

its

Investment

Committee

receive

and

consider,

among

other

matters,

information

regarding

the

performance

of

the

Funds.

Thus,

in

reaching

its

decisions

regarding

the

renewal

of

the

Agreement

for

each

Fund,

the

Board

took

into

account

the

information

described

herein

and

other

information

provided

to

the

Board

and

its

Committees

throughout

the

year.

The

Board

received

and

considered

both

Trust-level

and

Fund-specific

information,

but

made

its

renewal

determinations

on

a

Fund-by-

Fund

basis.

In

deciding

whether

to

renew

the

Agreement

for

each

Fund,

each

Trustee

may

have

accorded

different

weight

to

different

factors

and,

thus,

may

have

had

a

different

basis

for

his

or

her

ultimate

decision

to

vote

to

renew

the

Agreement

for

each

Fund.

At

its

meeting

on

March

10,

2023,

all

Board

members

voted

unanimously

to

renew

the

Agreement

for

each

Fund.

Set

forth

below

is

a

summary

of

the

primary

factors

that

the

Board

considered

with

respect

to

each

Fund.

428

Approval

of

Investment

Management

Agreement

(continued)

(Unaudited)

The

Nature,

Extent

and

Quality

of

Services

The

Board

considered

the

level

and

depth

of

knowledge

of

Advisors,

including

the

professional

experience

and

qualifications

of

its

personnel.

The

Board

also

considered

that

Advisors

is

an

experienced

investment

adviser

that

has

managed

the

Funds

since

their

operations

commenced.

Investment

professionals

at

Advisors

also

manage

various

funds

and

accounts

of

the

College

Retirement

Equities

Fund,

the

TIAA-CREF

Life

Funds

and

TIAA

Separate

Account

VA-1,

as

well

as

advise

and

sub-advise

other

investment

companies

and

vehicles.

Under

the

Agreement,

Advisors

is

responsible

for,

among

other

duties:

managing

the

assets

of

the

Funds,

including

conducting

research,

identifying

investments

and

placing

orders

to

buy

and

sell

securities

for

the

Funds’

investment

portfolios;

active

daily

monitoring

of

the

Funds’

investment

portfolios;

reporting

on

the

investment

performance

and

other

metrics

of

the

Funds

to

the

Board

on

a

regular

basis;

responding

to

Fund

flows;

compliance

monitoring;

coordinating

the

activities

of

each

Fund’s

service

providers;

and

overseeing

the

provision

of

various

administrative

services

to

the

Funds.

The

Board

considered

that

Advisors

has

carried

out

these

responsibilities

in

a

competent

and

professional

manner.

The

Board

also

considered

that

Advisors

has

committed

significant

resources

to

supporting

the

series

of

the

Trust,

including

the

Funds.

It

also

considered

Advisors’

compliance

program

and

resources

and

its

compliance

record

with

respect

to

the

Funds.

The

Board

also

considered,

among

other

factors,

the

performance

of

each

Fund,

as

discussed

below.

In

addition,

the

Board

considered

the

nature

and

quality

of

non-portfolio

management

services

provided

by

Advisors

and

its

affiliates.

In

this

regard,

the

Board

considered

its

ongoing

review

of

the

performance

of

certain

affiliated

and

unaffiliated

service

providers,

including

the

quality

of

services

provided

by

those

firms

and

Advisors’

oversight

of

those

service

providers

and

the

outsourcing

of

certain

services

to

other

firms.

During

its

review,

the

Board

noted

its

ongoing

review

of

the

level

of

personnel

and

other

resources

available

to

Advisors

to

provide

portfolio

management

and

other

services

to

the

Funds,

including

the

impact

of

recent

and

anticipated

regulatory

requirements

and

operational

changes

on

such

resources,

so

as

to

assess

the

adequacy

of

the

resources

devoted

to

these

services.

Based

on

all

factors

considered,

the

Board

concluded

that

the

nature,

extent,

and

quality

of

services

provided

by

Advisors

to

each

Fund

under

the

Agreement

was

reasonable.

Investment

Performance

The

Board

considered

the

investment

performance

of

each

Fund,

over

the

periods

indicated

in

the

Fund-by-Fund

synopsis

below.

The

Board

considered

each

Fund’s

performance

as

compared

to

its

peer

group

and

peer

universe

(as

applicable)

and

its

benchmark

index

or,

in

circumstances

in

which

a

Fund’s

peer

group

or

peer

universe

was

not

viewed

as

a

representative

basis

for

comparison,

other

comparative

information

deemed

relevant

by

management

and/or

the

Board.

The

Board

also

reviewed

the

three-year

performance

of

the

Bond

Index

and

Short-Term

Bond

Index

Funds

(the

“Index

Funds”)

before

any

reductions

for

fees

and

expenses.

In

this

analysis,

the

Board

considered

the

impact

of

net

asset

value

rounding

and

the

effects

of

fair

valuation,

foreign

exchange

rates,

effective

tax

rates,

securities

lending

and

class

action

litigation,

as

applicable,

on

each

Index

Fund’s

performance

as

compared

to

the

performance

of

its

benchmark

index.

For

details

regarding

each

Fund’s

performance,

see

the

Fund-by-Fund

synopsis

below.

The

Board

considered,

in

those

cases

in

which

a

Fund

had

performed

materially

differently

from

its

Broadridge

peers

or

benchmark

based

on

a

Board-established

threshold,

the

factors

identified

by

Advisors

that

contributed

to

such

difference

and

any

remedial

measures

being

undertaken,

or

planned

to

be

taken,

by

Advisors.

Thus,

the

Board

concluded

that,

under

the

totality

of

circumstances

considered,

the

investment

performance

of

each

Fund

was

reasonable

or

that

appropriate

actions

had

been

or

were

being

implemented.

Cost

and

Profitability

The

Board

considered

financial

and

profitability

data

relating

to

Advisors’

services

to

the

Funds

for

the

calendar

year

2022.

The

Board

considered

Advisors’

profit

calculations

with

respect

to

its

services

to

each

Fund

both

before

and

after

taking

into

account

the

costs

incurred

directly

or

indirectly

by

Advisors

in

connection

with

the

distribution

of

shares

of

the

Fund.

The

Board

acknowledged

the

reasonableness

of

having

management

fee

rates

which

permit

Advisors

to

maintain

and

improve

the

quality

of

services

provided

to

the

Funds

and

recognized

the

entrepreneurial

and

other

risks

assumed

by

Advisors

in

managing

the

Funds.

The

Board

considered

that

Advisors

had

calculated

that

it

earned

profits

with

respect

to

some

of

the

Funds

under

the

Agreement

for

the

one-year

period

ended

December

31,

2022.

However,

with

respect

to

the

Green

Bond,

Short-Term

Bond

Index,

Short

Duration

Impact

Bond

and

5-15

Year

Laddered

Tax-Exempt

Bond

Funds,

Advisors

calculated

that

it

had

incurred

losses

and,

with

respect

to

the

Money

Market

Fund,

it

had

broke

even.

The

Board

considered

Advisors’

voluntary

reduction

of

certain

Funds’

management

fee

rates:

0.015%

for

the

High-Yield

Fund,

0.015%

for

the

Core

Impact

Bond

Fund

and

0.020%

for

the

Inflation-Linked

Bond

Fund

during

the

year

ended

April

30,

2023

and

Advisors’

commitment

to

continue

this

voluntary

waiver

of

0.020%

for

the

Inflation-Linked

Bond

Fund

for

the

year

ending

April

30,

2024.

The

Board

also

considered

the

contractual

reduction

of

management

fees

for

the

Bond

Index

Fund

by

0.01%

and

for

the

Short-Term

Bond

Index

Fund

by

0.01%

starting

August

1,

2022.

The

Board

also

acknowledged

Advisors’

commitment

to

reimburse

Fund

expenses

to

the

extent

that

total

annual

operating

expenses

exceeded

certain

specified

amounts.

With

respect

to

those

Funds

for

which

the

Agreement

was

calculated

by

Advisors

to

be

profitable

to

Advisors

in

2022,

the

Board

concluded

that

those

profits

were

reasonable

in

light

of

various

relevant

factors.

429

Fees

Charged

by

Other

Advisers

The

Board

considered

comparative

information

regarding

each

Fund’s

contractual

and

effective

management

fee

rates

and

the

contractual

and

effective

management

fee

rates

paid

by

similar

mutual

funds

to

other

advisers,

as

analyzed

by

Broadridge

and

reflected

in

the

Fund-by-Fund

synopsis

below.

The

Board

determined

that

the

management

fee

rate

charged

to

a

Fund

under

the

Agreement

typically

was

lower

than

the

management

fee

rates

charged

to

many

or

most

other

comparable

mutual

funds.

In

this

regard,

the

Board

also

considered

the

inherent

limitations

of

such

comparisons

in

light

of

uncertainty

as

to

how

the

fees

of

such

similar

mutual

funds

are

set

and

potentially

material

differences

between

a

Fund

and

its

comparable

mutual

funds.

The

Board

considered

Broadridge’s

treatment

of

all

fund

fee

waivers,

regardless

of

their

type,

as

management

fee

waivers,

which

could

materially

impact

how

the

Funds’

actual

management

fee

rates

compare

to

those

of

similar

mutual

funds.

Additionally,

the

Board

considered

the

potential

limitations

of

such

comparisons

due

to,

among

other

factors,

the

fact

that,

in

many

instances,

Broadridge

based

its

comparisons

on

financial

data

relating

to

fiscal

periods

that

differed

from

the

period

for

which

the

Funds’

data

were

derived.

Based

on

all

factors

considered,

the

Board

concluded

that

the

management

fee

rates

under

the

Agreement

with

respect

to

each

Fund

were

reasonable

in

relation

to

those

charged

by

appropriate

groups

of

comparable

mutual

funds.

Economies

of

Scale

The

Board

considered

whether

Advisors

has

experienced

or

is

anticipated

to

experience

economies

of

scale

in

connection

with

the

operation

of

each

Fund,

and

whether

any

such

economies

are

shared

with

the

Funds.

The

Board

also

considered

the

extent

to

which

the

current

fee

rate

schedule

breakpoints

for

many

actively-managed

Funds

that

were

currently

profitable

to

Advisors

affected

Advisors’

fees.

The

Board

considered,

in

connection

with

the

supporting

Broadridge

reports,

Advisors’

position

that

the

maximum

fee

rate

that

could

be

charged

to

each

Fund

based

on

its

level

of

assets

under

the

Agreement

is

comparatively

low

in

relation

to

peer

groups

of

mutual

funds.

The

Board

also

considered

the

contractual

fee

rate

reductions

and

one-year

voluntary

management

fee

waivers

agreed

to

by

Advisors,

as

noted

above.

Based

on

all

factors

considered,

the

Board

concluded

that

the

Funds’

management

fee

rate

schedules

were

reasonable

in

light

of

current

economies

of

scale

considerations

and

current

asset

levels.

Fee

and

Performance

Comparisons

with

Other

Advisors

Clients

The

Board

considered

that

Advisors

and

its

affiliate,

TIAA-CREF

Investment

Management,

LLC,

provide

investment

management

services

to

other

investment

companies,

including

other

mutual

funds,

foreign

funds

(UCITS),

collective

investment

trusts

(“CITs”)

and

separately

managed

accounts

that

may

have

similar

investment

strategies

as

certain

of

the

Funds.

In

particular,

the

Board

considered

the

management

fee

rates

Advisors

charges

to

separately

managed

accounts,

UCITS

series

and

CITs

that

have

similar

mandates

to

the

Core

Bond,

Core

Bond

Plus,

Green

Bond

and

Core

Impact

Bond

Funds

and

the

performance

of

such

accounts/

series.

The

Board

also

considered

Advisors’

comments

that,

in

the

future,

Advisors

may

manage

client

assets

through additional

funds

and

accounts

with

similar

investment

strategies.

The

Board

also

considered

Advisors’

representation

that,

while

the

management

fee

rates

charged

to

the

Funds

may

differ

from

the

management

fee

rates

chargeable

to

these

other

funds

and

accounts,

this

may

be

due

in

part

to

the

fact

that

these

other

funds

and

accounts

may:

(1)

involve

less

entrepreneurial

risk

on

the

part

of

Advisors;

(2)

be

offered

in

different

types

of

markets;

(3)

be

provided

with

different

types

or

levels

of

services;

(4)

have

different

regulatory

burdens;

and/or

(5)

target

different

investors.

Based

on

all

factors

considered,

the

Board

concluded

that

the

management

fee

rates

under

the

Agreement

with

respect

to

each

Fund

were

reasonable

in

relation

to

those

charged

by

Advisors

to

its

comparable

clients.

Other

Benefits

The

Board

also

considered

additional

“fall-out

benefits”

to

Advisors

and

its

affiliates

arising

from

the

Agreement.

Such

benefits

include,

among

others,

other

fees

paid

by

the

Funds

to

Advisors

or

its

affiliates

for

other

services,

such

as

distribution

and

administration,

and

investment-related

benefits,

such

as

economies

of

scale

to

the

extent

the

Funds

share

investment

resources

and/or

personnel

with

other

clients

of

Advisors

and

the

ability

to

incubate

strategies

within

one

or

more

Funds

that

could

be

subsequently

utilized

to

manage

other

non-Fund

products.

Advisors

and

its

affiliates

may

also

benefit

from

the

level

of

business

and

relationships

the

Funds

have

with

certain

service

providers.

Additionally,

the

Funds

may

be

utilized

as

investment

options

for

other

products

and

businesses

of

Advisors

and

its

affiliates,

such

as

variable

products,

fund

of

funds

and

529

education

savings

plans.

Also,

Advisors

and

its

affiliates

may

benefit

from

their

relationship

with

the

Funds

to

the

extent

that

this

relationship

results

in

potential

investors

viewing

Teachers

Insurance

and

Annuity

Association

of

America,

of

which

Advisors

is

an

indirect,

wholly-owned

subsidiary,

as

a

leading

retirement

plan

provider

in

the

academic

and

non-profit

markets

and

as

a

single

source

for

all

their

financial

service

needs.

The

Board

concluded

that

other

benefits

to

Advisors

and

its

affiliates

arising

from

the

Agreement

were

reasonable

in

light

of

various

relevant

factors.

430

Approval

of

Investment

Management

Agreement

(continued)

(Unaudited)

Fund-by-Fund

Synopsis

of

Factors

The

Board

considered

the

following

specific

factors

(among

others)

in

connection

with

its

determination

to

renew

the

Agreement

with

respect

to

each

Fund.

If

a

Fund

is

described

in

the

following

discussions

as

being

in

the

“1st”

quintile,

it

is

in

the

best

of

five

groups

(that

is,

the

group

has

the

best

performance

or

the

lowest

expenses,

as

the

case

may

be).

References

below

to

quintiles

are

based

on

data

provided

to

the

Board

in

the

reports

prepared

by

Broadridge.

The

specific

management

fee,

expense

and

performance

factors

outlined

below

are

based

on

the

Institutional

Class

of

each

Fund.

Because

the

Institutional

Class

generally

has

lower

non-

management

expenses

than

the

other

classes

of

these

Funds,

the

expenses

and

performance

of

these

other

classes

will

differ

from

the

expenses

and

performance

shown

for

the

Institutional

Class.

References

to

“adjusted”

gross

performance

means

the

performance

of

a

Fund

without

any

reductions

for

fees

and

expenses,

including

the

effect

of

net

asset

value

rounding

and

excluding

the

effects

of

fair

valuation,

foreign

exchange

rates,

effective

tax

rates,

securities

lending

and

class

action

litigation,

as

respond

to

the

Funds’

liquidity

developments.

In

accordance

with

the

Program,

the

LMAT

assesses

each

Fund’s

liquidity

risk

no

less

frequently

than

annually

based

on

various

factors,

such

as

(i)

the

Fund’s

investment

strategy

and

the

liquidity

of

portfolio

investments,

(ii)

cash

flow

projections,

and

(iii)

holdings

of

cash

and

cash

equivalents

and

borrowing

arrangements

and

other

funding

sources.

Certain

factors

are

considered

under

both

normal

and

reasonably

foreseeable

stressed

conditions.

Each

Fund

portfolio

investment

is

classified

into

one

of

four

liquidity

categories

(including

“highly

liquid

investments”

and

“illiquid

investments,”

discussed

below).

The

classification

is

based

on

a

determination

of

how

long

it

is

reasonably

expected

to

take

to

convert

the

investment

into

cash,

or

sell

or

dispose

of

the

investment,

in

current

market

conditions

without

significantly

changing

the

market

value

of

the

investment.

Liquidity

classification

determinations

take

into

account

various

market,

trading,

and

investment-

specific

considerations,

as

well

as

market

depth,

and

utilize

third-party

vendor

data.

Any

Fund

that

does

not

primarily

hold

highly

liquid

investments

must,

among

other

things,

determine

a

minimum

percentage

of

Fund

net

assets

that

must

be

invested

in

highly

liquid

investments

(a

“Highly

Liquid

Investment

Minimum”).

During

the

Review

Period,

each

Fund

primarily

held

highly

liquid

investments

and

therefore

was

exempt

from

the

requirement

to

adopt

a

Highly

Liquid

Investment

Minimum

and

to

comply

with

the

related

requirements

under

the

Liquidity

Rule.

The

Liquidity

Rule

also

limits

the

Funds’

investments

in

illiquid

investments.

Specifically,

the

Liquidity

Rule

prohibits

acquisition

of

illiquid

investments

if

doing

so

would

result

in

the

Fund

holding

more

than

15%

of

its

net

assets

in

illiquid

investments

and

requires

certain

reporting

anytime

a

Fund’s

holdings

of

illiquid

investments

exceed

15%

of

net

assets.

During

the

Review

Period,

no

Fund

exceeded

the

15%

limit

on

illiquid

investments.

Brad

Finkle

Real

estate

investment

trusts

(REITs)

posted

a

loss

for

the

twelve

months

ended

March

31,

2023,

amid

persistent

inflation

and

a

substantial

rise

in

interest

rates.

The

Federal

Reserve

addressed

elevated

inflation

by

increasing

the

federal

funds

target

rate—a

key

measure

of

short-term

interest

rates—multiple

times

during

the

period.

The

most

recent

increase

in

March

2023

brought

the

rate

to

4.75%–

5.00%.

The

U.S.

economy

stumbled

early

in

the

period

but

expanded

during

the

third

and

fourth

quarters

of

2022,

driven

by

strong

consumer

spending,

while

the

unemployment

rate

remained

at

near

50-year

lows.

Energy

prices

rose

at

the

start

of

the

period

and

continued

through

the

beginning

of

June

2022,

but

then

fell

back

steadily

by

the

end

of

the

period.

REITs

returned

–19.4%

for

the

twelve

months,

as

measured

by

the

FTSE

Nareit

All

Equity

REITs

Index.

Please

see

page

5

for

the

benchmark

definition.

Most

of

the

index’s

16

property

sectors

and

subsectors

declined,

with

the

office

sector

posting

the

largest

loss.

The

TIAA-CREF

Real

Estate

Securities

Fund

(Institutional

Class)

trailed

its

benchmark

for

the

period.

REITs

trailed

U.S.

bonds

and

stocks

REITs

are

a

unique

asset

class

because

they

share

some

of

the

characteristics

of

both

stocks

and

bonds.

Like

bonds,

REIT

prices

can

be

sensitive

to

interest-

rate

fluctuations,

and

throughout

the

period,

REITs

struggled

due

to

the

rise

in

interest

rates.

Similar

to

equities,

REITs

invest

in

individual

companies,

so

their

performance

is

tied

to

the

overall

health

of

the

U.S.

economy.

As

such,

weakness

in

the

stock

market

hurt

the

returns

of

REITs

during

the

period.

For

the

twelve

months,

the

FTSE

Nareit

All

Equity

REITs

Index

trailed

the

–4.8%

return

of

the

broad

U.S.

investment-grade

fixed-rate

bond

market,

as

measured

by

the

Bloomberg

U.S.

Aggregate

Bond

Index.

REITs

also

lagged

all

other

fixed-income

sectors,

including

high-yield

bonds,

as

well

as

the

–8.6%

return

of

the

broad

U.S.

stock

market,

as

measured

by

the

Russell

3000®

Index.

Maintaining

perspective

during

challenging

market

conditions

Although

REITs

performed

well

at

the

beginning

of

2023,

they

have

struggled

since

last

year

due

to

the

impact

that

higher

interest

rates

have

had

on

the

commercial

and

residential

real

estate

markets.

Additionally,

the

failure

of

several

U.S.

banks

has

put

pressure

on

the

banking

industry

and

dampened

the

financial

markets

in

general.

Despite

today’s

challenging

financial

environment,

however,

REITs

historically

have

provided

investors

with

a

relatively

stable

source

of

income

and

return.

REITs

have

the

potential

to

rise

in

value,

like

a

stock,

while

also

producing

a

steady

source

of

income—similar

to

a

bond.

REITs

are

required

by

law

to

distribute

at

least

90%

of

their

taxable

income

to

investors

in

the

form

of

dividends.

As

such,

they

generate

current

income,

which

can

be

a

valuable

feature

when

interest

rates

decline

or

when

markets

are

volatile.

Furthermore,

REITs

invest

in

a

broad

spectrum

of

real

estate

properties,

and

each

sector

possesses

its

own

supply/

demand

dynamics

and

its

own

characteristics.

That

variation

of

sectors

plays

a

vital

role

in

determining

the

performance

of

REIT

securities.

Moreover,

the

broad

array

of

REITs

held

in

a

professionally

managed

real

estate

securities

mutual

fund

has

the

potential

to

add

value

as

a

diversification

tool

when

combined

with

a

portfolio

of

stocks,

bonds

and

other

assets.

Of

course,

diversification

cannot

guarantee

against

market

losses.

No

one

can

predict

which

way

financial

markets

will

move

or

foresee

the

direction

of

interest

rates.

Because

of

these

uncertainties,

we

believe

that

a

professionally

managed

mutual

fund

of

REIT

securities,

designed

to

mitigate

volatility,

can

play

an

integral

role

in

a

long-term

investment

plan.

Expense

Examples

All

shareholders

of

the

TIAA-CREF

Funds

incur

ongoing

costs,

including

management

fees

and

other

fund

expenses.

They

may

also

incur

transactional

costs

for

redemptions

or

account

maintenance

fees.

The

expense

example

that

appears

in

this

report

is

intended

to

help

you

understand

your

ongoing

costs

only

(in

U.S.

dollars)

and

does

not

reflect

transactional

costs.

The

example

is

designed

to

help

you

compare

these

ongoing

costs

with

the

ongoing

costs

of

investing

in

other

mutual

funds.

The

expenses

shown

do

not

include

account

maintenance

fees,

which

may

or

may

not

be

applicable,

as

described

in

the

prospectus.

If

such

fees

were

included,

your

total

costs

for

investing

in

the

Fund

would

be

higher.

Note

also

that

shareholders

of

the

TIAA-CREF

Funds

do

not

incur

a

sales

charge

for

purchases,

reinvested

dividends

or

other

distributions.

The

example

is

based

on

an

investment

of

$1,000

invested

at

the

beginning

of

the

six-month

period

and

held

for

the

entire

period

(

October

1,

2022

–

March

31,

2023

).

Actual

expenses

The

first

section

in

the

table

uses

the

Fund’s

actual

expenses

and

its

actual

rate

of

return.

You

may

use

the

information

in

this

section,

together

with

the

amount

you

invested,

to

estimate

the

expenses

that

you

paid

over

the

six-month

period.

Simply

divide

your

account

value

by

$1,000

(for

example,

an

$8,600

account

value

divided

by

$1,000

=

8.6),

then

multiply

the

result

by

the

number

in

the

first

line

under

the

heading

“Expenses

incurred

during

the

period”

to

estimate

the

expenses

you

paid

during

the

six-month

period.

Hypothetical

example

for

comparison

purposes

The

second

section

in

the

table

shows

hypothetical

account

values

and

expenses

based

on

the

Fund’s

actual

expense

ratio

for

each

share

class

for

the

six-month

period

and

an

assumed

5%-per-year

rate

of

return

before

expenses.

This

was

not

the

share

class’

actual

return.

This

hypothetical

example

cannot

be

used

to

estimate

the

actual

expenses

you

paid

for

the

period,

but

rather

allows

you

to

compare

the

ongoing

costs

of

investing

in

the

Fund

with

the

costs

of

other

funds.

To

do

so,

compare

this

5%

hypothetical

example

with

the

5%

hypothetical

examples

that

appear

in

the

shareholder

reports

of

other

mutual

funds.

There

were

The

charges

of

may

reflect

a

waiver

reimbursement.

Please

see

the

prospectus

for

an

explanation,

including

the

date

on

which

this

reimbursement

is

scheduled

to

end.

Without

such

waiver

and/or

the

would

be

higher

and

their

lower.

Opinion

on

We

have

audited

the

accompanying

of

including

the

of

TIAA-CREF

Real

(one

hereafter

referred

in

the

period

ended

March

(collectively

referred

to

as

In

our

opinion,

the

present

fairly,

in

all

material

respects,

the

financial

position

of

the

Fund

as

of

March

the

Basis

for

Opinion

These

financial

statements

are

the

responsibility

of

the

Fund’s

management.

Our

responsibility

is

to

express

an

opinion

on

the

Fund’s

financial

statements

based

on

our

audits.

We

are

a

public

accounting

firm

registered

with

the

Public

Company

Accounting

Oversight

Board

(United

States)

(“PCAOB”)

and

are

required

to

be

independent

with

respect

to

the

Fund

in

accordance

with

the

U.S.

federal

securities

laws

and

the

applicable

rules

and

regulations

of

the

Securities

and

Exchange

Commission

and

the

PCAOB.

We

conducted

our

audits

of

these

financial

statements

in

accordance

with

the

standards

of

the

PCAOB.

Those

standards

require

that

we

plan

and

perform

the

audit

to

obtain

reasonable

assurance

about

whether

the

financial

statements

are

free

of

material

misstatement,

whether

due

to

error

or

fraud.

Our

audits

included

performing

procedures

to

assess

the

risks

of

material

misstatement

of

the

financial

statements,

whether

due

to

error

or

fraud,

and

performing

procedures

that

respond

to

those

risks.

Such

procedures

included

examining,

on

a

test

basis,

evidence

regarding

the

amounts

and

disclosures

in

the

financial

statements.

Our

audits

also

included

evaluating

the

accounting

principles

used

and

significant

estimates

made

by

management,

as

well

as

evaluating

the

overall

presentation

of

the

financial

statements.

Our

procedures

included

confirmation

of

securities

owned

as

of

March

31,

2023

by

correspondence

with

the

custodian

and

brokers;

when

replies

were

not

received

from

brokers,

we

performed

other

auditing

procedures.

We

believe

that

our

audits

provide

a

reasonable

basis

for

our

opinion.

2—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.

The Fund is

an

investment

company

and

follows

the

accounting

guidance

in

the

Financial

Accounting

Standards

Board

(“FASB”)

Accounting

Standards

Codification

Services

—

Investment

Companies

.

The net

asset

value (“NAV”) for

financial

reporting

purposes

may

differ

from

the NAV

for

processing

transactions.

The NAV

for

financial

reporting

purposes

includes

security

and 

shareholder

transactions

through

the

date

of

the

report.

Total

return

is

computed

based

on

the NAV

used

for

processing

transactions.

The

following

is

a

summary

of

the

significant

accounting

policies

consistently

followed

by

the

Fund.

basis

and

includes

accretion

of

discounts

and

recorded

on

the

ex-dividend

date.

Foreign

dividend

income

is

or

as

soon

as

possible

after

the

Fund determines

the

existence

of

a

Foreign

Taxes:

The

Fund may

be

subject

to

foreign

taxes

on

income,

gains

on

investments

or

currency

repatriation,

a

portion

of

which

may

be

recoverable.

The

Fund

will

accrue

such

taxes

and

recoveries

as

applicable,

based

upon

the

current

interpretation

of

tax

rules

and

regulations

that

exist

in

the

markets

in

which

the

Fund

invests.

Trustee

Compensation:

The

Fund pays

the

members

of

the

Board

of

Trustees

(“Board”),

all

of

whom

are

independent,

certain

remuneration

for

their

services,

plus

travel

and

other

expenses.

Trustees

may

elect

to

participate

in

a

deferred

compensation

plan

and

defer

all

or

a

portion

of

their

compensation.

In

addition,

trustees

participate

in

a

long-term

compensation

plan.

Amounts

deferred

are

retained

by

the

Fund

until

paid. Amounts

payable

to

the

trustees

for

compensation

are

included

separately in

the

accompanying

Statement

of

Assets

and

Liabilities. Trustees’

fees,

including

any

deferred

and

long-term

compensation

incurred,

are

reflected

in

the

Statement

of

Operations.

Indemnification:

 Under

the

Trust's

organizational

documents,

its

officers

and

trustees

are

indemnified

against

certain

liabilities

arising

out

of

the

performance

of

their

duties

to

the

Trust.

In

addition,

in

the

normal

course

of

business,

the

Trust

enters

into

contracts

that

provide

general

indemnifications

to

other

parties.

The

Trust's

maximum

exposure

under

these

arrangements

is

unknown

as

this

would

involve

future

claims

that

may

be

made

against

the

Trust

that

have

not

yet

occurred.

However,

the

Trust

has

not

had

prior

claims

or

losses

pursuant

to

these

contracts

and

expects

the

risk

of

loss

to

be

remote.

New

Rule

Issuance:

 A

new

rule

adopted

by

the

SEC

governing

fund

valuation

practices,

Rule

2a-5

under

the

1940

Act,

has

established

requirements

for

determining

fair

value

in

good

faith

for

purposes

of

the

1940

Act.

Rule

2a-5

permits

fund

boards

to

designate

certain

parties

to

perform

fair

value

determinations,

subject

to

board

oversight

and

certain

other

conditions.

Rule

2a-5

also

defines

when

market

quotations

are

"readily

available"

for

purposes

of

Section

2(a)(41)

of

the

1940

Act,

which

requires

a

fund

to

fair

value

a

security

when

market

quotations

are

not

readily

available.

Separately,

new

SEC

Rule

31a-4

under

the

1940

Act

sets

forth

the

recordkeeping

requirements

associated

with

fair

value

determinations. The

Fund

adopted

a

valuation

policy

conforming

to

the

new

rules,

effective

September

1,

2022,

and

there

was

no

material

impact

to

the

Fund.

New

Accounting

Pronouncement:

 In

June

2022,

the

FASB

issued

ASU

2022-03

to

clarify

the

guidance

in

Topic

820,

Fair

Value

Measurement

(“Topic

820”).

The

amendments

in

ASU

2022-03

affect

all

entities

that

have

investments

in

equity

securities

measured

at

fair

value

that

are

subject

to

a

contractual

sale

restriction.

ASU

2022-03

(1)

clarifies

the

guidance

in

Topic

820,

when

measuring

the

fair

value

of

an

equity

security

subject

to

contractual

restrictions

that

prohibit

the

sale

of

an

equity

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

fair

value

in

accordance

with

Topic

820.

For

public

business

entities,

the

amendments

in

ASU

2022-03

are

effective

for

fiscal

years

beginning

after

December

15,

2023,

and

interim

periods

within

those

fiscal

years.

For

all

other

entities,

the

amendments

are

effective

for

fiscal

years

beginning

after

December

15,

2024,

and

interim

periods

within

those

fiscal

years.

Early

adoption

is

permitted

for

both

interim

and

annual

financial

statements

that

have

not

yet

been

issued

or

made

available

for

issuance.

Management

is

currently

assessing

the

impact

of

these

provisions

on

the

Fund's

financial

statements.

Note

3—Valuation

of

Investments

The Fund’s

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

that

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 Fund's

major

classifications

of

assets

and

liabilities

measured

at

fair

value

Debt

Securities:

Prices

of

fixed-income

securities

are

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

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.

Exchange-Traded

Equity

Securities,

Common

and

Preferred

Stock:

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 Fund’s

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. 

Investments

in

Registered

Investment

Companies:

Investments

in

investment

companies

are

valued

at

their

respective NAVs

or

share

price

on

the

valuation

date

and

are

generally

classified

as Level

1.

Repurchase

Agreements:

Repurchase

agreements

are

valued

at

contract

amount

plus

accrued

interest,

which

approximates

market

value.

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 Fund’s

investments

as

of

the

end

of

the

reporting

period,

based

on

the

inputs

used

to

value

them: 

Note

4—Investments

Repurchase

Agreements:

In

connection

with

transactions

in

repurchase

agreements,

it

is

the Fund’s policy

that

its

custodian

take

possession

of

the

underlying

collateral

securities,

the

fair

value

of

which

exceeds

the

principal

amount

of

the

repurchase

transaction,

including

accrued

interest,

at

all

times.

If

the

counterparty

defaults,

and

the

fair

value

of

the

collateral

declines,

realization

of

the

collateral

may

be

delayed

or

limited.

Information

The Fund

intends

to

distribute

substantially

all

of

its

net

investment

income

and

net

capital

gains

to

shareholders

and

otherwise

comply

with

the

requirements

of

Subchapter

M

of

the

Internal

Revenue

Code

applicable

to

regulated

investment

companies.

Therefore,

no

federal

income

tax

provision

is

required.

The

Fund

files

income

tax

returns

in

U.S.

federal

and

applicable

state

and

local

jurisdictions.

A Fund’s

federal

income

tax

returns

are

generally

subject

to

examination

for

a

period

of

three

fiscal

years

after

being

filed.

State

and

local

tax

returns

may

be

subject

to

examination

for

an

additional

period

of

time

depending

on

the

jurisdiction.

Management

has

analyzed

the

Fund’s

tax

positions

taken

for

all

open

tax

years

and

has

concluded

that

no

provision

for

income

tax

is

required

in

the

Fund’s

financial

statements.

Differences

between

amounts

for

financial

statement

and

federal

income

tax

purposes

are

primarily

due

to

timing

differences

in

recognizing

gains

and

losses

on

investment

transactions.

Temporary

differences

do

not

require

reclassification.

As

of

year

end,

permanent

differences

that

resulted

in

reclassifications

among

the

components

of

net

assets

relate

primarily

to

deemed

dividend

due

to

corporate

actions,

distribution

reallocations,

foreign

currency

transactions,

and

taxes

paid.

Temporary

and

permanent

differences

have

no

impact

on

a

Fund’s

net

assets.

As

of

year

end,

the

aggregate

cost

and

the

net

unrealized

appreciation/(depreciation)

of

all

investments

for

federal

income

tax

purposes

were

as

The

Fund

receives

voluntary

compensation

from

the

Adviser

in

amounts

that

approximate

the

cost

of

research

services

obtained

from

broker-dealers

and

research

providers

if

the

Adviser

had

purchased

the

research

services

directly.

This

income

received

by

the

Fund

is

recognized

in

"Other

income"

on

the

Statement

of

Operations.

During

the

current

fiscal

period,

the

values

of

voluntary

compensation

were

as

follows:

The

Fund may

purchase

or

sell

investment

securities

in

transactions

with

affiliated

entities

under

procedures

adopted

by

the

Board,

pursuant

to

the

1940

Act.

These

transactions

are

effected

at

market

rates

without

incurring

broker

commissions.

During

the

current

fiscal

period,

these

transactions

did

not

materially

impact

the

Fund.

A

registered

separate

account

of

TIAA

(collectively

“TIAA

Access”)

has

various

sub-accounts

that

invest

in

the

Fund,

and

certain

funds

within

the

Trust

also

make

investments

in

the

Fund.

The

following

is

the

percentage

of

the

Fund's

shares

owned

by

affiliates

as

of

the

end

of

the

reporting

period:

Companies

in

which

the

Fund

holds

5%

or

more

of

the

outstanding

voting

shares

are

considered

"affiliated

companies"

of

the

Fund,

pursuant

to

the

1940

Act.

During

the

current

fiscal

period,

there

were

no

affiliated

investments.

Note

8—Inter-Fund

Lending

Program

Pursuant

to

an

exemptive

order

issued

by

the

SEC,

the

Fund

may

participate

in

an

inter-fund

lending

program.

This

program

allows

the

Fund

to

lend

cash

to

and/or

borrow

cash

from

certain other

affiliated

Funds

for

temporary

purposes,

(e.g.,

to

satisfy

redemption

requests

or

to

cover

unanticipated

cash

shortfalls).

The

program

is

subject

to

a

number

of

conditions,

including

the

requirement

that

the Fund

may

not

borrow

or

lend

money

under

the

program

unless

it

receives

a

more

favorable

interest

rate

than

is

available

from

a

bank

or

other

financial

institution

for

a

comparable

transaction.

In

addition,

the

Fund

may

participate

in

the

program

only

if

its

participation

is

consistent

with

the

Fund’s

investment

policies

and

limitations

and

authorized

by

its

portfolio

manager(s).

During

the current

reporting

period,

there

were

no

inter-fund

borrowing

or

lending

transactions.

Note

9—Line

of

Credit

The Fund

participates

in

a

$1

billion

unsecured

revolving

credit

facility

that

can

be

used

for

temporary

purposes,

including,

without

limitation,

the

funding

of

shareholder

redemptions.

The

current

facility

was

entered

into

on

June

14,

2022

expiring

on

June

13,

2023,

replacing

the

previous facility,

which

expired

June

2022.

Certain

affiliated

accounts

and

mutual

funds,

each

of

which

is

managed

by the

Adviser,

or

an

affiliate

of

the

Adviser, also

participate

in

this

facility.

An

annual

commitment

fee

for

the

credit

facility

is

borne

by

the

participating

accounts

and

mutual

funds

on

a

pro

rata

basis.

Interest

associated

with

any

borrowing

under

the

facility

is

charged

to

the

borrowing

accounts

or

mutual

funds

at

a

specified

rate

of

interest.

The Fund is

not

liable

for

borrowings

under

the

facility

by

other

affiliated

accounts

or

mutual

funds.

There

were

no

borrowings

under

this

credit

facility

by

the

Fund during

the

current

reporting

period.

Note

10—Subsequent

Events

The

Adviser

has

agreed

to

implement

a

voluntary

waiver

reducing

the

management

fee

breakpoint

schedule

for

the

Real

Securities

Fund

for

one

year

effective

May

1,

2023.

This

waiver

is

voluntary

in

nature

and

can

be

at

any

time

without

(the

between

Teachers

Below

is

a

of

the

process

the

Board

undertook

related

to

its

most

recent

renewal

of

the

Agreement

with

respect

to

the

TIAA-CREF

Real

Estate

(the

“Fund”).

Section

15(c)

of

as

amended

(the

Act”),

requires

that,

after

an

initial

period

of

up

to

two

years,

the

Agreement

for

the

Fund

will

remain

in

effect

only

if

the

Board,

including

a

majority

of

those

Trustees

who

have

no

direct

or

indirect

interest

in

the

Agreement,

and

who

are

independent

Trustees

because

they

are

not

“interested

persons”

of

the

Trust,

as

that

term

is

defined

in

the

1940

Act,

annually

renews

the

Agreement.

None

of

the

Trustees

is

an

interested

person

of

the

Trust

under

the

1940

Act.

Rather,

they

are

all

deemed

to

be

independent

Trustees.

Overview

of

the

Renewal

Process

The

Board

held

an

in-person

meeting

on

March

10,

2023,

in

order

to

consider

the

annual

renewal

of

the

Agreement

for

the

Fund

using

the

process

established

by

the

Board

described

further

below.

As

part

of

the

Board’s

established

process,

the

Board

delegated

certain

tasks

to

its

Operations

Committee.

Among

these

tasks,

the

Operations

Committee

or

certain

of

its

designated

members

worked

with

Advisors,

other

Board

members

and

legal

counsel

to

the

Trustees

to

develop

guidance

and

specific

requests

relating

to

the

types

of

information

to

be

provided

to

the

Board

in

connection

with

the

proposed

contract

renewals.

Among

other

matters,

the

Operations

Committee

or

certain

of

its

designated

members,

following

consultations

with

representatives

of

Advisors,

other

Board

members,

legal

counsel

to

the

Trustees

and

legal

counsel

to

Advisors

and

the

Trust,

confirmed

or

established

certain

guidance

regarding

the

preparation

of

reports

to

be

provided

to

the

Board

with

respect

to

the

Fund

by

the

Board

Reporting

and

Compliance

unit

of

Broadridge

Financial

Solutions,

Inc.

(“Broadridge”),

using

data

from

Lipper,

Inc.,

an

independent

provider

of

investment

company

data.

The

Operations

Committee

considered

that

Broadridge

is

widely

recognized

as

a

leading

provider

of

comparative

analyses

used

by

independent

directors

and

trustees

of

investment

companies

during

their

advisory

contract

review

processes.

Based

on

guidance

provided

by

the

Operations

Committee

or

certain

of

its

designated

members,

on

behalf

of

the

Board,

Broadridge

produced,

among

other

information,

comparative

performance

and

expense

data

for

the

Fund,

including

data

relating

to

the

Fund’s

management

fee

rate,

total

expense

ratio,

short-term

and

long-term

investment

performance,

brokerage

commission

costs

and

portfolio

turnover

rate.

Broadridge

compared

this

data,

as

relevant,

for

the

Fund

against

a

universe

of

investment

companies

(except

for

brokerage

commission

costs

and

turnover

rates)

and

against

a

more

selective

peer

group

of

mutual

funds

with

similar

investment

objectives

and

strategies,

each

of

which

was

selected

by

Broadridge,

and

also

compared

the

performance

of

the

Fund

against

one

or

more

appropriate

broad-based

indices.

In

each

case,

Broadridge

summarized,

and

the

Board

considered,

the

methodologies

Broadridge

employed

to

provide

the

data

contained

in

its

reports.

In

addition,

Broadridge

represented

to

the

Board

that

its

reports

were

designed

specifically

to

provide

the

Board

with

the

fee,

expense

and

performance

information

that

is

necessary

to

help

the

Board

satisfy

its

duties

under

Section

15(c)

of

the

1940

Act.

Broadridge

also

represented

that

the

purpose

of

its

reports

is

to

provide

an

objective

view

of

the

Fund’s

relative

position

regarding

the

level

of

fees,

expenses

and

performance

against

a

competitive

peer

group

and

universe

(as

applicable)

selected

by

Broadridge

(and

not

Advisors

or

the

Board).

The

Board

considered

the

propriety

of

the

Fund’s

applicable

peer

group

as

selected

by

Broadridge

and

use

of

the

Institutional

Class

as

the

base

class

for

comparison

purposes.

Among

other

matters,

the

Board

also

(9)

draft

narrative

explanations

to

Trustees

were

also

provided

with

performance

ratings

of

Morningstar,

Inc.

(“Morningstar”),

which

is

a

widely

recognized

mutual

fund

ranking

service.

On

March

2,

2023,

the

Board

held

a

virtual

meeting

via

videoconference

with

legal

counsel

to

the

Trustees

to

discuss

Advisors’

materials,

which

led

to

the

Trustees

providing

additional

questions

to,

and

requesting

additional

information

from,

Advisors.

Subsequently,

at

the

March

10,

2023

meeting,

the

Trustees

were

given

the

opportunity

to,

and

did,

ask

additional

questions

and

they

discussed

responses

from

Advisors

to

the

Board’s

follow-up

questions

and

requests

presented

by

the

Board

after

its

initial

review

of

the

information

described

above.

In

considering

whether

to

renew

the

Agreement

with

respect

to

the

Fund,

the

Board

considered

various

factors,

including:

(1)

the

nature,

extent

and

quality

of

services

provided

or

to

be

provided

by

Advisors

to

the

Fund;

(2)

the

Fund’s

investment

performance;

(3)

the

costs

of

the

services

provided

to

the

Fund

and

the

profits

realized

or

potential

profits

to

be

realized

by

Advisors

and

its

affiliates

from

their

relationship

with

the

Fund;

(4)

fees

charged

to

comparable

mutual

funds

by

other

advisers;

(5)

the

extent

to

which

economies

of

scale

have

been

realized

or

are

anticipated

to

be

realized

as

the

Fund

grows;

(6)

how

such

economies

of

scale

are

shared

with

the

Fund

for

the

benefit

of

its

investors,

such

as

through

management

fee

breakpoints;

(7)

comparisons

of

the

services

provided

by

Advisors

to,

and

the

fee

rates

and

performance

of,

the

Fund

to

other

clients

to

whom

Advisors

provides

comparable

services;

and

(8)

any

other

benefits

identified

by

Advisors

derived

or

anticipated

to

be

derived

by

Advisors

or

its

affiliates

from

their

relationship

with

the

Fund.

As

a

general

matter,

the

Board

considered

these

factors,

and

any

other

factors

deemed

relevant

by

the

Trustees,

in

their

totality,

and

no

single

factor

was

identified

as

being

the

determining

factor

in

deciding

whether

to

renew

the

Agreement.

In

addition

to

the

March

10,

2023

meeting

that

included

Advisors’

personnel,

the

Trustees

met

in

executive

sessions,

at

which

no

representatives

of

Advisors

were

present,

to

discuss

the

proposed

renewal

of

the

Agreement

for

the

Fund.

The

Board

also

received

and

considered

information

from

its

legal

counsel

as

to

certain

relevant

guidance

that

relates

to

the

renewal

process

under

Section

15(c)

of

the

1940

Act

and

certain

other

legal

authorities.

While

the

contract

renewal

process

included

a

series

of

discussions

and

meetings

leading

up

to

the

March

10,

2023

meeting,

the

oversight

and

evaluation

of

Advisors’

services

to

the

Fund

by

the

Board

and

its

Committees

is

an

ongoing

process.

The

Board,

as

well

as

its

Committees,

considered

reports

on

various

investment

and

operational

topics

that

had

been

identified

by

the

Board

or

its

Committees

for

review

in

the

year

since

the

last

annual

renewal

process.

Further,

at

their

regularly

scheduled

meetings,

the

Board

and

its

Investment

Committee

receive

and

consider,

among

other

matters,

information

regarding

the

performance

of

the

Fund.

Thus,

in

reaching

its

decisions

regarding

the

renewal

of

the

Agreement

for

the

Fund,

the

Board

took

into

account

the

information

described

herein

and

other

information

provided

to

the

Board

and

its

Committees

throughout

the

year.

The

Board

received

and

considered

both

Trust-level

and

Fund-specific

information,

but

made

its

renewal

determinations

on

a

Fund-

level

basis.

In

deciding

whether

to

renew

the

Agreement

for

the

Fund,

each

Trustee

may

have

accorded

different

weight

to

different

factors

and,

thus,

may

have

had

a

different

basis

for

his

or

her

ultimate

decision

to

vote

to

renew

the

Agreement

for

the

Fund.

At

its

meeting

on

March

10,

2023,

all

Board

members

voted

unanimously

to

renew

the

Agreement

for

the

Fund.

Set

forth

below

is

a

summary

of

the

primary

factors

that

the

Board

considered

with

respect

to

the

Fund.

31

The

Nature,

Extent

and

Quality

of

Services

The

Board

considered

the

level

and

depth

of

knowledge

of

Advisors,

including

the

professional

experience

and

qualifications

of

its

personnel.

The

Board

also

considered

that

Advisors

is

an

experienced

investment

adviser

that

has

managed

the

Fund

since

its

operations

commenced.

Investment

professionals

at

Advisors

also

manage

various

funds

and

accounts

of

the

College

Retirement

Equities

Fund,

the

TIAA-CREF

Life

Funds

and

TIAA

Separate

Account

VA-1,

as

well

as

advise

and

sub-advise

other

investment

companies

and

vehicles.

Under

the

Agreement,

Advisors

is

responsible

for,

among

other

duties:

managing

the

assets

of

the

Fund,

including

conducting

research,

identifying

investments

and

placing

orders

to

buy

and

sell

securities

for

the

Fund’s

investment

portfolio;

active

daily

monitoring

of

the

Fund’s

investment

portfolio;

reporting

on

the

investment

performance

and

other

metrics

of

the

Fund

to

the

Board

on

a

regular

basis;

responding

to

Fund

flows;

compliance

monitoring;

coordinating

the

activities

of

the

Fund’s

service

providers;

and

overseeing

the

provision

of

various

administrative

services

to

the

Fund.

The

Board

considered

that

Advisors

has

carried

out

these

responsibilities

in

a

competent

and

professional

manner.

The

Board

also

considered

that

Advisors

has

committed

significant

resources

to

supporting

the

series

of

the

Trust,

including

the

Fund.

It

also

considered

Advisors’

compliance

program

and

resources

and

its

compliance

record

with

respect

to

the

Fund.

The

Board

also

considered,

among

other

factors,

the

performance

of

the

Fund,

as

discussed

below.

In

addition,

the

Board

considered

the

nature

and

quality

of

non-portfolio

management

services

provided

by

Advisors

and

its

affiliates.

In

this

regard,

the

Board

considered

its

ongoing

review

of

the

performance

of

certain

affiliated

and

unaffiliated

service

providers,

including

the

quality

of

services

provided

by

those

firms

and

Advisors’

oversight

of

those

service

providers

and

the

outsourcing

of

certain

services

to

other

firms.

During

its

review,

the

Board

noted

its

ongoing

review

of

the

level

of

personnel

and

other

resources

available

to

Advisors

to

provide

portfolio

management

and

other

services

to

the

Fund,

including

the

impact

of

recent

and

anticipated

regulatory

requirements

and

operational

changes

on

such

resources,

so

as

to

assess

the

adequacy

of

the

resources

devoted

to

these

services.

Based

on

all

factors

considered,

the

Board

concluded

that

the

nature,

extent,

and

quality

of

services

provided

by

Advisors

to

the

Fund

under

the

Agreement

was

reasonable.

Investment

Performance

The

Board

considered

the

investment

performance

of

the

Fund

over

the

one-,

three-,

five-

and

ten-year

periods

ended

December

31,

2022.

The

Board

considered

the

Fund’s

performance

as

compared

to

its

peer

group

and

peer

universe

and

its

benchmark

index.

For

details

regarding

the

Fund’s

performance,

see

the

Fund

synopsis

below.

The

Board

concluded

that,

under

the

totality

of

circumstances

considered,

the

investment

performance

of

the

Fund

was

reasonable.

Cost

and

Profitability

The

Board

considered

financial

and

profitability

data

relating

to

Advisors’

services

to

the

Funds

for

the

calendar

year

2022.

The

Board

considered

Advisors’

profit

calculations

with

respect

to

its

services

to

the

Fund

both

before

and

after

taking

into

account

the

costs

incurred

directly

or

indirectly

by

Advisors

in

connection

with

the

distribution

of

shares

of

the

Fund.

The

Board

acknowledged

the

reasonableness

of

having

a

management

fee

rate

that

permits

Advisors

to

maintain

and

improve

the

quality

of

services

provided

to

the

Fund

and

recognized

the

entrepreneurial

and

other

risks

assumed

by

Advisors

in

managing

the

Fund.

The

Board

considered

that

Advisors

calculated

that

it

had

earned

profits

with

respect

to

the

Fund

under

the

Agreement

for

the

one-year

period

ended

December

31,

2022.

The

Board

also

considered

Advisors’

voluntary

reduction

of

the

Fund’s

management

fee

rate

by

0.035%

from

May

1,

2022

to

April

30,

2023,

as

well

as

Advisors’

voluntary

reduction

of

the

Fund’s

management

fee

rate

by

0.020%

starting

May

1,

2023

through

April

30,

2024.

The

Board

also

acknowledged

Advisors’

commitment

to

reimburse

Fund

expenses

to

the

extent

that

total

annual

operating

expenses

exceeded

a

specified

amount.

The

Board

concluded

that

the

profits

earned

by

Advisors

in

2022

from

its

services

to

the

Fund

were

reasonable

in

light

of

various

relevant

factors.

Fees

Charged

by

Other

Advisers

The

Board

considered

comparative

information

regarding

the

Fund’s

contractual

and

effective

management

fee

rates

and

the

contractual

and

effective

management

fee

rates

paid

by

similar

mutual

funds

to

other

advisers,

as

analyzed

by

Broadridge

and

reflected

in

the

Fund

synopsis

below.

The

Board

determined

that

the

management

fee

rate

charged

to

the

Fund

under

the

Agreement

typically

was

lower

than

the

management

fee

rates

charged

to

most

other

comparable

mutual

funds.

In

this

regard,

the

Board

also

considered

the

inherent

limitations

of

such

comparisons

in

light

of

uncertainty

as

to

how

the

fees

of

such

similar

mutual

funds

are

set

and

potentially

material

differences

between

the

Fund

and

its

comparable

mutual

funds.

The

Board

considered

Broadridge’s

treatment

of

all

fund

fee

waivers,

regardless

of

their

type,

as

management

fee

waivers,

which

could

materially

impact

how

the

Fund’s

actual

management

fee

rate

compares

to

those

of

similar

mutual

funds.

Additionally,

the

Board

considered

the

potential

limitations

of

such

comparisons

due

to,

among

other

factors,

the

fact

that,

in

many

instances,

Broadridge

based

its

comparisons

on

financial

data

relating

to

fiscal

periods

that

differed

from

the

period

for

which

the

Fund’s

data

were

derived.

Based

on

all

factors

considered,

the

Board

concluded

that

the

management

fee

rate

under

the

Agreement

with

respect

to

the

Fund

was

reasonable

in

relation

to

those

charged

by

appropriate

groups

of

comparable

mutual

funds.

32

Approval

of

Investment

Management

Agreement

(continued)

(Unaudited)

Economies

of

Scale

The

Board

considered

whether

Advisors

has

experienced

or

is

anticipated

to

experience

economies

of

scale

in

connection

with

the

operation

of

the

Fund,

and

whether

any

such

economies

are

shared

with

the

Fund.

The

Board

also

considered

the

extent

to

which

the

current

fee

rate

schedule

breakpoints

of

the

Fund

affected

Advisors’

fees.

The

Board

considered,

in

connection

with

the

supporting

Broadridge

reports,

Advisors’

position

that

the

maximum

fee

rate

that

could

be

charged

to

the

Fund

based

on

its

level

of

assets

under

the

Agreement

is

comparatively

low

in

relation

to

peer

groups

of

mutual

funds.

The

Board

also

considered

Advisors’

compensation

of

the

Fund

for

all

of

the

soft

dollar

amounts

the

Fund

spent

on

research

during

the

year.

Based

on

all

factors

considered,

the

Board

concluded

that

the

Fund’s

management

fee

rate

schedule

was

reasonable

in

light

of

current

economies

of

scale

considerations

and

the

Fund’s

current

asset

level.

Fee

and

Performance

Comparisons

with

Other

Advisors

Clients

The

Board

considered

that

Advisors

and

its

affiliate,

TIAA-CREF

Investment

Management,

LLC,

provide

investment

management

services

to

other

investment

companies,

including

foreign

funds

(UCITS),

and

separately

managed

accounts.

The

Board

considered

that

Advisors

did

not

currently

manage

any

other

products

with

comparable

investment

strategies

to

the

Fund’s

investment

strategy.

The

Board

also

considered

Advisors’

comments

that,

in

the

future,

Advisors

may

manage

client

assets

through additional

funds

and

accounts

with

similar

investment

strategies

except

for

the

TIAA-CREF

Life

Real

Estate

Securities

Fund.

The

Board

also

considered

Advisors’

representation

that,

while

the

management

fee

rate

charged

to

the

Fund

may

differ

from

the

management

fee

rates

chargeable

to

these

other

funds

and

accounts,

this

may

be

due

in

part

to

the

fact

that

these

other

funds

and

accounts

may:

(1)

involve

less

entrepreneurial

risk

on

the

part

of

Advisors;

(2)

be

offered

in

different

types

of

markets;

(3)

be

provided

with

different

types

or

levels

of

services;

(4)

have

different

regulatory

burdens;

and/or

(5)

target

different

investors.

Based

on

all

factors

considered,

the

Board

concluded

that

the

management

fee

rate

under

the

Agreement

with

respect

to

the

Fund

was

reasonable

in

relation

to

those

charged

by

Advisors

to

its

comparable

clients.

Other

Benefits

The

Board

also

considered

additional

“fall-out

benefits”

to

Advisors

and

its

affiliates

arising

from

the

Agreement.

Such

benefits

include,

among

others,

other

fees

paid

by

the

Fund

to

Advisors

or

its

affiliates

for

other

services,

such

as

distribution

and

administration,

and

investment-related

benefits,

such

as

economies

of

scale

to

the

extent

the

Fund

shares

investment

resources

and/or

personnel

with

other

clients

of

Advisors.

Advisors

and

its

affiliates

may

also

benefit

from

the

level

of

business

and

relationships

the

Funds

have

with

certain

service

providers.

Additionally,

the

Fund

may

be

utilized

as

investment

options

for

other

products

and

businesses

of

Advisors

and

its

affiliates,

such

as

variable

products,

fund

of

funds

and

529

education

savings

plans.

Also,

Advisors

and

its

affiliates

may

benefit

from

their

relationship

with

the

Fund

to

the

extent

that

this

relationship

results

in

potential

investors

viewing

Teachers

Insurance

and

Annuity

Association

of

America,

of

which

Advisors

is

an

indirect,

wholly-owned

subsidiary,

as

a

leading

retirement

plan

provider

in

the

academic

and

non-profit

markets

and

as

a

single

source

for

all

their

financial

service

needs.

The

Board

concluded

that

other

benefits

to

Advisors

and

its

affiliates

arising

from

the

Agreement

were

reasonable

in

light

of

various

relevant

factors.

Fund

Synopsis

of

Factors

The

Board

considered

the

following

specific

factors

(among

others)

in

connection

with

its

determination

to

renew

the

Agreement

with

respect

to

the

Fund.

If

the

Fund

is

described

in

the

following

discussions

as

being

in

the

“1st”

quintile,

it

is

in

the

best

of

five

groups

(that

is,

the

group

has

the

best

performance

or

the

lowest

expenses,

as

the

case

may

be).

References

below

to

quintiles

are

based

on

data

provided

to

the

Board

in

the

reports

prepared

by

Broadridge.

The

specific

management

fee,

expense

and

performance

factors

outlined

below

are

based

on

the

Institutional

Liquidity

Risk

Management

Program

34

Discussion

of

the

operation

and

effectiveness

of

the

Fund’s

liquidity

risk

management

program

In

compliance

with

Rule

22e-4

under

the

Investment

Company

Act

of

1940,

as

amended

(the

“Liquidity

Rule”),

the

series

of

the

Trust

covered

by

this

Report

(the

“Fund”)

has

adopted

and

implemented

a

liquidity

risk

management

program

(the

“Program”),

which

is

reasonably

designed

to

assess

and

manage

the

Fund’s

liquidity

risk.

The

Program

consists

of

various

provisions

relating

to

assessing

and

managing

Fund

liquidity

risk,

as

discussed

further

below.

The

Fund’s

Board

of

Trustees

(the

“Board”)

previously

approved

the

designation

of

Advisors

(the

“Administrator”)

as

Program

administrator.

The

Liquidity

Monitoring

and

Analysis

Team

(the

“LMAT”)

carries

out

day-to-day

Program

management

with

oversight

by

the

Liquidity

Oversight

Committee

(the

“LOSC”).

Personnel

from

the

Administrator

and

Nuveen

Fund

Advisors,

LLC,

an

affiliate

of

the

Administrator,

comprise

the

LMAT

and

LOSC.

At

a

February

14,

2023

Board

meeting,

the

Administrator

provided

the

Board

with

a

written

report

addressing

the

Program’s

operation,

adequacy,

and

effectiveness

of

implementation

for

the

period

from

January

1,

2022

through

December

31,

2022

(the

“Review

Period”),

as

required

under

the

Liquidity

Rule.

The

report

noted

that

the

Program

has

been

and

continues

to

be

adequately

and

effectively

implemented

to

monitor

and

(as

applicable)

respond

to

the

Fund’s

liquidity

developments.

In

accordance

with

the

Program,

the

LMAT

assesses

the

Fund’s

liquidity

risk

no

less

frequently

than

annually

based

on

various

factors,

such

as

(i)

the

Fund’s

investment

strategy

and

the

liquidity

of

portfolio

investments,

(ii)

cash

flow

projections,

and

(iii)

holdings

of

cash

and

cash

equivalents

and

borrowing

arrangements

and

other

funding

sources.

Certain

factors

are

considered

under

both

normal

and

reasonably

foreseeable

stressed

conditions.

Fund

portfolio

investments

are

classified

into

one

of

four

liquidity

categories

(including

“highly

liquid

investments”

and

“illiquid

investments,”

discussed

below).

The

classification

is

based

on

a

determination

of

how

long

it

is

reasonably

expected

to

take

to

convert

the

investment

into

cash,

or

sell

or

dispose

of

the

investment,

in

current

market

conditions

without

significantly

changing

the

market

value

of

the

investment.

Liquidity

classification

determinations

take

into

account

various

market,

trading,

and

investment-

specific

considerations,

as

well

as

market

depth,

and

utilize

third-party

vendor

data.

A

Fund

that

does

not

primarily

hold

highly

liquid

investments

must,

among

other

things,

determine

a

minimum

percentage

of

Fund

net

assets

that

must

be

invested

in

highly

liquid

investments

(a

“Highly

Liquid

Investment

Minimum”).

During

the

Review

Period,

the

Fund

primarily

held

highly

liquid

investments

and

therefore

was

exempt

from

the

requirement

to

adopt

a

Highly

Liquid

Investment

Minimum

and

to

comply

with

the

related

requirements

under

the

Liquidity

Rule.

The

Liquidity

Rule

also

limits

the

Fund’s

investments

in

illiquid

investments.

Specifically,

the

Liquidity

Rule

prohibits

acquisition

of

illiquid

investments

if

doing

so

would

result

in

the

Fund

holding

more

than

15%

of

its

net

assets

in

illiquid

investments

and

requires

certain

reporting

anytime

a

Fund’s

holdings

of

illiquid

investments

exceed

15%

of

net

assets.

During

the

Review

Period,

the

Fund

did

not

exceed

the

15%

limit

on illiquid

investments.

Item 2. Code of Conduct.

2(a)    The Board of Trustees of the TIAA-CREF Funds (the “Registrant”) has adopted a code of conduct for senior financial officers, including the Registrant’s principal executive officer, principal financial officer, principal accounting officer, or controller, and persons performing similar functions, in conformity with rules promulgated under the Sarbanes-Oxley Act of 2002.

2(b)    No response required.

2(c)    During the reporting period, there were no material amendments to the code of conduct.

2(d)    During the reporting period, there were no implicit or explicit waivers granted by the Registrant from any provision of the code of conduct.

2(e)    Not applicable.

2(f)    The Registrant has posted the code of ethics on its website at

          www.tiaa.org/public/pdf/c/code_of_conduct.pdf.

Item 3. Audit Committee Financial Expert.

3(a)(1) The Registrant’s Board of Trustees has determined that the Registrant has at least one audit committee financial expert serving on its Audit and Compliance Committee.

3(a)(2) Thomas J. Kenny is the Registrant’s audit committee financial expert and is “independent” for purposes of Item 3 of Form N-CSR.

Item 4. Principal Accountant Fees and Services.

PricewaterhouseCoopers LLP (“PwC”) performs independent audits of the Registrant’s financial statements. To maintain auditor independence and avoid even the appearance of conflicts of interest, the Registrant, as a policy, does not engage PwC for management advisory or consulting services.

The aggregate fees billed by PwC as disclosed below for the fiscal year ended March 31, 2022 may not align with the figures reported and filed with the Securities and Exchange Commission in the Form N-CSR for the fiscal year ended March 31, 2022 because the fees disclosed in this Form N-CSR reflect fees updated after the date of the March 31, 2022 Form N-CSR.

4(a)    Audit Fees.

For the fiscal years ended March 31, 2023 and March 31, 2022, PwC’s aggregate fees for the audit of the Registrant’s annual financial statements were $655,482 and $628,830, respectively.

4(b)    Audit Related Fees.

For the fiscal years ended March 31, 2023 and March 31, 2022, PwC’s aggregate fees for services related to the performance of the audit of the Registrant’s annual financial statements were $0 and $0, respectively.

For the fiscal years ended March 31, 2023 and March 31, 2022, the Audit-Related Fees billed by PwC to Teachers Advisors, LLC (“Advisors”) or to any entity controlling, controlled by or under common control with Advisors that provides ongoing services to the Registrant (collectively, “Fund Service Providers”) were $0 and $0, respectively.

4(c)    Tax Fees.

For the fiscal years ended March 31, 2023 and March 31, 2022, PwC’s aggregate fees for tax services billed to the Registrant were $99 and $0, respectively.

For the fiscal years ended March 31, 2023 and March 31, 2022, the Tax Fees billed by PwC to the Fund Service Providers were $0 and $0, respectively.

4(d)    All Other Fees.

For the fiscal years ended March 31, 2023 and March 31, 2022, PwC’s aggregate fees for all other services billed to the Registrant were $1,311 and $0, respectively.

For the fiscal years ended March 31, 2023 and March 31, 2022, PwC’s aggregate fees for all other services billed to the Fund Service Providers were $0 and $0, respectively.

4(e)(1) Preapproval Policy.

The Registrant’s audit and compliance committee (“Audit Committee”) has adopted a Preapproval Policy for External Audit Firm Services (the “Policy”). The Policy describes the types of services that may be provided by the independent auditor to the Registrant and certain of its affiliates without impairing the auditor’s independence. Under the Policy, the Audit Committee is required to preapprove all services to be performed by the Registrant’s independent auditor in order to ensure that such services do not impair the auditor’s independence.

The Policy requires the Audit Committee to: (i) appoint the independent auditor to perform the financial statements audit for the Registrant and certain of its affiliates, including approving the terms of the engagement, and (ii) preapprove the audit, audit- related, tax and other services to be provided by the independent auditor to the Registrant and certain of its affiliates and the fees to be charged for provision of such services from year to year.

4(e)(2) Services provided pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X (the “de minimis exception”):

Audit-Related Fees:

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception for the fiscal years ended March 31, 2023 and March 31, 2022 on behalf of the Registrant.

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception for the fiscal years ended March 31, 2023 and March 31, 2022 on behalf of the Fund Service Providers that relate directly to the operations and financial reporting of the Registrant.

Tax Fees:

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception for the fiscal years ended March 31, 2023 and March 31, 2022 on behalf of the Registrant.

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception for the fiscal years ended March 31, 2023 and March 31, 2022 on behalf of the Fund Service Providers that relate directly to the operations and financial reporting of the Registrant.

All Other Fees:

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception for the fiscal years ended March 31, 2023 and March 31, 2022 on behalf of the Registrant.

There were no amounts that were approved by the Audit Committee pursuant to the de minimis exception for the fiscal years ended March 31, 2023 and March 31, 2022 on behalf of the Fund Service Providers that relate directly to the operations and financial reporting of the Registrant.

4(f)    The percentage of hours expended by PwC’s engagement to audit the Registrant’s financial statements for the most recent fiscal year attributable to work performed by persons other than PwC’s full-time, permanent employees was less than 50%.

4(g)    Non-Audit Fees for Related Entities.

For the fiscal years ended March 31, 2023 and March 31, 2022, aggregate non-audit fees billed to the Registrant and to its Fund Service Providers by PwC were $1,402,275 and $1,067,853, respectively.

4(h)    The Registrant’s Audit Committee has considered whether the non-audit services that were rendered by PwC to the Registrant’s Fund Service Providers that were not pre-approved pursuant to paragraph (c)(7)(ii) of Rule 2-01 of Regulation S-X are compatible with maintaining PwC’s independence.
