management 2019s discussion and analysis of financial condition and results of operations ( continued ) funding deposits : we provide products and services including custody , accounting , administration , daily pricing , foreign exchange services , cash management , financial asset management , securities finance and investment advisory services .
as a provider of these products and services , we generate client deposits , which have generally provided a stable , low-cost source of funds .
as a global custodian , clients place deposits with state street entities in various currencies .
we invest these client deposits in a combination of investment securities and short- duration financial instruments whose mix is determined by the characteristics of the deposits .
for the past several years , we have experienced higher client deposit inflows toward the end of the quarter or the end of the year .
as a result , we believe average client deposit balances are more reflective of ongoing funding than period-end balances .

these assets provide liquidity through maturities of the assets , but more importantly , they provide us with the ability to raise funds by pledging the securities as collateral for borrowings or through outright sales .

agency credit ratings our ability to maintain consistent access to liquidity is fostered by the maintenance of high investment-grade ratings as measured by the major independent credit rating agencies .
factors essential to maintaining high credit ratings include diverse and stable core earnings ; relative market position ; strong risk management ; strong capital ratios ; diverse liquidity sources , including the global capital markets and client deposits ; strong liquidity monitoring procedures ; and preparedness for current or future regulatory developments .
high ratings limit borrowing costs and enhance our liquidity by providing assurance for unsecured funding and depositors , increasing the potential market for our debt and improving our ability to offer products , serve markets , and engage in transactions in which clients value high credit ratings .
a downgrade or reduction of our credit ratings could have a material adverse effect on our liquidity by restricting our ability to access the capital .
