The Company’s regulated subsidiaries maintain agreements with other water purveyors for the purchase of water to supplement their water supply.
The following table provides the future annual commitments related to minimum quantities of purchased water having non-cancelable:
## Table 0 ##
The Company enters into agreements for the provision of services to water and wastewater facilities for the United States military, municipalities and other customers.
See Note 3—Revenue Recognition for additional information regarding the Company’s performance obligations.
Contingencies The Company is routinely involved in legal actions incident to the normal conduct of its business.
As of December 31, 2018, the Company has accrued approximately $54 million of probable loss contingencies and has estimated that the maximum amount of losses associated with reasonably possible loss contingencies that can be reasonably estimated is $26 million.
For certain matters, claims and actions, the Company is unable to estimate possible losses.
The Company believes that damages or settlements, if any, recovered by plaintiffs in such matters, claims or actions, other than as described in this Note 16—Commitments and Contingencies, will not have a material adverse effect on the Company.
West Virginia Elk River Freedom Industries Chemical Spill On June 8, 2018, the U. S.  District Court for the Southern District of West Virginia granted final approval of a settlement class and global class action settlement (the “Settlement”) for all claims and potential claims by all putative class members (collectively, the “Plaintiffs”) arising out of the January 2014 Freedom Industries, Inc.  chemical spill in West Virginia.
The effective date of the Settlement is July 16, 2018.
Under the terms and conditions of the Settlement, West Virginia-American Water Company (“WVAWC”) and certain other Company affiliated entities (collectively, the “American Water Defendants”) did not admit, and will not admit, any fault or liability for any of the allegations made by the Plaintiffs in any of the actions that were resolved.
Under federal class action rules, claimants had the right, until December 8, 2017, to elect to opt out of the final Settlement.
Less than 100 of the 225,000 estimated putative class members elected to opt out from the Settlement, and these claimants will not receive any benefit from or be bound by the terms of the Settlement.
In June 2018, the Company and its remaining non-participating general liability insurance carrier settled for a payment to the Company of $20 million, out of a maximum of $25 million in potential coverage under the terms of the relevant policy, in exchange for a full release by the American Water Defendants of all claims against the insurance carrier related to the Freedom Industries chemical spill.
Offsetting of Securities Financing Agreements The Corporation enters into securities financing agreements to accommodate customers (also referred to as “matched-book transactions”), obtain securities to cover short positions, and to finance inventory positions.
Substantially all of the Corporation’s securities financing activities are transacted under legally enforceable master repurchase agreements or legally enforceable master securities lending agreements that give the Corporation, in the event of default by the counterparty, the right to liquidate securities held and to offset receivables and payables with the same counterparty.
The Securities Financing Agreements table presents securities financing agreements included on the Consolidated Balance Sheet in federal funds sold and securities borrowed or purchased under agreements to resell, and in federal funds purchased and securities loaned or sold under agreements to repurchase at December 31,2017 and 2016.
Balances are presented on a gross basis,prior to the application of counterparty netting.
Gross assets and liabilities are adjusted on an aggregate basis to take into consideration the effects of legally enforceable master netting agreements.
For more information on the offsetting of derivatives, see Note 2 – Derivatives.
## Table 1 ##
(1) Includes activity where uncertainty exists as to the enforceability of certain master netting agreements under bankruptcy laws in some countries or industries.
(2) Includes securities collateral received or pledged under repurchase or securities lending agreements where there is a legally enforceable master netting agreement.
These amounts are not offset on the Consolidated Balance Sheet, but are shown as a reduction to derive a net asset or liability.
Securities collateral received or pledged where the legal enforceability of the master netting agreements is uncertain is excluded from the table.
(3) Excludes repurchase activity of $10.2 billion and $10.1 billion reported in loans and leases on the Consolidated Balance Sheet at December 31, 2017 and 2016.
(4) Balance is reported in accrued expenses and other liabilities on the Consolidated Balance Sheet and relates to transactions where the Corporation acts as the lender in a securities lending agreement and receives securities that can be pledged as collateral or sold.
In these transactions,the Corporation recognizes an asset at fair value,representing the securities received, and a liability,representing the obligation to return those securities.
Repurchase Agreements and Securities Loaned Transactions Accounted for as Secured Borrowings The following tables present securities sold under agreements to repurchase and securities loaned by remaining contractual term to maturity and class of collateral pledged.
Included in “Other” are transactions where the Corporation acts as the lender in a securities lending agreement and receives securities that can be pledged as collateral or sold.
Certain agreements contain a right to substitute collateral and/or terminate the agreement prior to maturity at the option of the Corporation or the counterparty.
Such agreements are included in the table below based on the remaining contractual term to maturity
## Table 2 ##
(1) No agreements have maturities greater than three years.
term rates on an increased deposit base and the impact of the allocation of ALM activities, partially offset by credit spread compression.
Noninterest income increased $521 million to $9.5 billion largely due to higher investment banking fees.
The provision for credit losses decreased $671 million to $212 million in 2017 primarily driven by reductions in energy exposures and continued portfolio improvement, partially offset by Global Banking’s portion of a single-name non-U.
S.  commercial chargeoff.
Noninterest expense increased $110 million to $8.6 billion in 2017 primarily driven by higher investments in technology and higher deposit insurance, partially offset by lower litigation costs.
The return on average allocated capital was 17 percent,up from 15 percent, as higher net income was partially offset by an increased capital allocation.
For more information on capital allocated to the business segments, see Business Segment Operations on page 46.
Global Corporate, Global Commercial and Business Banking Global Corporate, Global Commercial and Business Banking each include Business Lending and Global Transaction Services activities.

The table below and following discussion present a summary of the results, which exclude certain investment banking activities in Global Banking
## Table 3 ##
Business Lending revenue increased $271 million in 2017 compared to 2016 driven by the impact of loan and lease-related growth and the allocation of ALM activities, partially offset by credit spread compression.
Global Transaction Services revenue increased $734 million in 2017 compared to 2016 driven by the impact of higher shortterm rates on an increased deposit base, as well as the allocation of ALM activities.
Average loans and leases increased four percent in 2017 compared to 2016 driven by growth in the commercial and industrial, and leasing portfolios.
Average deposits increased three percent due to growth with new and existing clients.
Global Investment Banking Client teams and product specialists underwrite and distribute debt, equity and loan products, and provide advisory services and tailored risk management solutions.
The economics of certain investment banking and underwriting activities are shared primarily between Global Banking and Global Markets under an internal revenue-sharing arrangement.
To provide a complete discussion of our consolidated investment banking fees, the following table
## Table 4 ##
Total Corporation investment banking fees, excluding self-led deals, of $6.0 billion, which are primarily included within Global Banking and Global Markets, increased 15 percent in 2017 compared to 2016 driven by higher advisory fees and higher debt and equity issuance fees due to an increase in overall client activity and market fee pools.
