These matters, if resolved adversely against us or settled, may result in monetary awards or payments, fines and penalties or require changes in our business practices. The resolution or settlement of these matters is inherently difficult to predict. Based on our assessment of these pending matters, we do not believe that the amount of any judgment, settlement or other action arising from any pending matter is likely to have a material adverse effect on our consolidated financial condition. However, an adverse outcome or development in certain of the matters described below could have a material adverse effect on our consolidated results of operations for the period in which such matter is resolved, or an accrual is determined to be required, on our consolidated financial condition, or on our reputation. </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We evaluate our needs for accruals of loss contingencies related to legal and regulatory proceedings on a case-by-case basis. When we have a liability that we deem probable, and we deem the amount of such liability can be reasonably estimated as of the date of our consolidated financial statements, we accrue our estimate of the amount of loss. We also consider a loss probable and establish an accrual when we make, or intend to make, an offer of settlement. Once established, an accrual is subject to subsequent adjustment as a result of additional information. The resolution of legal and regulatory proceedings and the amount of reasonably estimable loss (or range thereof) are inherently difficult to predict, especially in the early stages of proceedings. Even if a loss is probable, an amount (or range) of loss might not be reasonably estimated until the later stages of the proceeding due to many factors such as the presence of complex or novel legal theories, the discretion of governmental authorities in seeking sanctions or negotiating resolutions in civil and criminal matters, the pace and timing of discovery and other assessments of facts and the procedural posture of the matter (collectively, "factors influencing reasonable estimates"). </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">As of </span><span style="font-family:Arial;font-size:10pt;">December 31, 2019</span><span style="font-family:Arial;font-size:10pt;">, our aggregate accruals for loss contingencies for legal, regulatory and related matters totaled approximately </span><span style="font-family:Arial;font-size:10pt;"><span>$146 million</span></span><span style="font-family:Arial;font-size:10pt;">, including potential fines by government agencies and civil litigation with respect to the matters specifically discussed below. To the extent that we have established accruals in our consolidated statement of condition for probable loss contingencies, such accruals may not be sufficient to cover our ultimate financial exposure associated with any settlements or judgments. Any such ultimate financial exposure, or proceedings to which we </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">may become subject in the future, could have a material adverse effect on our businesses, on our future consolidated financial statements or on our reputation. </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">As of </span><span style="font-family:Arial;font-size:10pt;">December 31, 2019</span><span style="font-family:Arial;font-size:10pt;">, for those matters for which we have accrued probable loss contingencies (including the Invoicing Matter described below) and for other matters for which loss is reasonably possible (but not probable) in future periods, and for which we are able to estimate a range of reasonably possible loss, our estimate of the aggregate reasonably possible loss (in excess of any accrued amounts) ranges up to approximately </span><span style="font-family:Arial;font-size:10pt;"><span>$50 million</span></span><span style="font-family:Arial;font-size:10pt;">. Our estimate with respect to the aggregate reasonably possible loss is based upon currently available information and is subject to significant judgment and a variety of assumptions and known and unknown uncertainties, which may change quickly and significantly from time to time, particularly if and as we engage with applicable governmental agencies or plaintiffs in connection with a proceeding. Also, the matters underlying the reasonably possible loss will change from time to time. As a result, actual results may vary significantly from the current estimate.</span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In certain pending matters, it is not currently feasible to reasonably estimate the amount or a range of reasonably possible loss, and such losses, which may be significant, are not included in the estimate of reasonably possible loss discussed above. This is due to, among other factors, the factors influencing reasonable estimates described above. An adverse outcome in one or more of the matters for which we have not estimated the amount or a range of reasonably possible loss, individually or in the aggregate, could have a material adverse effect on our businesses, on our future consolidated financial statements or on our reputation. Given that our actual losses from any legal or regulatory proceeding for which we have provided an estimate of the reasonably possible loss could significantly exceed such estimate, and given that we cannot estimate reasonably possible loss for all legal and regulatory proceedings as to which we may be subject now or in the future, no conclusion as to our ultimate exposure from current pending or potential legal or regulatory proceedings should be drawn from the current estimate of reasonably possible loss. </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The following discussion provides information with respect to significant legal, governmental and regulatory matters. </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:normal;text-decoration:none;">Invoicing Matter</span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In 2015, we determined that we had incorrectly invoiced clients for certain expenses. We have reimbursed most of our affected customers for those expenses, and we have implemented enhancements to our billing processes. In connection with our enhancements to our billing processes, we continue to review historical billing practices and may from time to time identify additional remediation. In 2017, we </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">identified an additional area of incorrect expense billing associated with mailing services in our retirement services business. We currently expect the cumulative total of our payments to customers for these invoicing errors, including the error in the retirement services business, to be at least </span><span style="font-family:Arial;font-size:10pt;"><span>$380 million</span></span><span style="font-family:Arial;font-size:10pt;">, all of which has been paid or is accrued. However, we may identify additional remediation costs.</span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In March 2017, a purported class action was commenced against us alleging that our invoicing practices violated duties owed to retirement plan customers under the Employee Retirement Income Security Act. In addition, we have received a purported class action demand letter alleging that our invoicing practices were unfair and deceptive under Massachusetts law. A class of customers, or particular customers, may assert that we have not paid to them all amounts incorrectly invoiced, and may seek double or treble damages under Massachusetts law. </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We are also cooperating with investigations by governmental and regulatory authorities on these matters, including the civil and criminal divisions of the DOJ and the DOL, which reviews could result in significant fines or other sanctions, civil and criminal, against us. In June 2019, we reached an agreement with the SEC to settle its claims that we violated the recordkeeping provisions of Section 34(b) of the Investment Company Act of 1940 and caused violations of Section 31(a) of the Investment Company Act and Rules 31a-1(a) and 31a-1(b) thereunder in connection with our overcharges of customers which are registered investment companies. In reaching this settlement, we neither admitted nor denied the claims contained in the SEC’s order, and agreed to pay a civil monetary penalty of </span><span style="font-family:Arial;font-size:10pt;"><span>$40 million</span></span><span style="font-family:Arial;font-size:10pt;">. Also in June 2019, we reached an agreement with the Massachusetts Attorney General’s office to resolve its claims related to this matter. In reaching this settlement, we neither admitted nor denied the claims in the order, and agreed to pay a civil monetary penalty of </span><span style="font-family:Arial;font-size:10pt;"><span>$5.5 million</span></span><span style="font-family:Arial;font-size:10pt;">. The costs associated with these settlements were within our related previously established accruals for loss contingencies. The SEC and Massachusetts Attorney General’s office settlements both recognize that the payment of </span><span style="font-family:Arial;font-size:10pt;"><span>$48.8 million</span></span><span style="font-family:Arial;font-size:10pt;"> in disgorgement and interest is satisfied by our direct reimbursements of our customers. </span></div><div style="line-height:120%;padding-bottom:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In late January 2020, the DOJ outlined a framework for a possible resolution of their review. We intend to attempt to negotiate a settlement of this matter with the DOJ. We expect that any settlement with the DOJ will include both financial and non-financial provisions. Separately, we have inquired of the DOL as to the status of their review. There can be no assurance that any settlement with the DOJ or DOL will be reached on financial or other terms acceptable to us or at all. The aggregate amount of penalties that may potentially be imposed upon us in connection with the resolution </span></div><div style="line-height:120%;padding-bottom:4px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">of all outstanding investigations into our historical billing practices is not currently known. We have increased our legal accrual with respect to the pending government investigations and civil litigation with respect to this matter. However, our ultimate liability with respect to this matter might be significantly in excess of our current accrual.</span><span style="font-family:Arial;font-size:10pt;"> Government authorities have significant discretion in criminal and civil matters as to the fines and other penalties they may seek to impose. Any resolution of the DOJ and DOL claims may involve penalties that could be a significant percentage, or a multiple of, all or a portion of the overcharge. The severity of such fines or penalties could take into account factors such as the amount or duration of our incorrect invoicing and the government’s or regulators’ assessment of the conduct of our employees, as well as prior conduct such as that which resulted in our January 2017 deferred prosecution agreement and settlement of civil claims regarding our indirect FX business. </span></div><div style="line-height:120%;padding-bottom:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">The outcome of any of these proceedings and, in particular, any criminal sanction could materially adversely affect our results of operations and could have significant collateral consequences for our business and reputation. </span></div><div style="line-height:120%;padding-top:6px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:normal;text-decoration:none;">Federal Reserve/Massachusetts Division of Banks Written Agreement</span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">On June 1, 2015, we entered into a written agreement with the Federal Reserve and the Massachusetts Division of Banks relating to deficiencies identified in our compliance programs with the requirements of the Bank Secrecy Act, Anti-Money Laundering regulations and U.S. economic sanctions regulations promulgated by the Office of Foreign Assets Control. As part of this enforcement action, we have been required to, among other things, implement improvements to our compliance programs. If we fail to comply with the terms of the written agreement, we may become subject to fines and other regulatory sanctions, which may have a material adverse effect on us.</span></div><div style="line-height:120%;padding-top:4px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;font-style:italic;font-weight:normal;text-decoration:none;">Shareholder Litigation</span></div><div style="line-height:120%;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">A shareholder of ours has filed a derivative complaint against the Company’s past and present officers and directors to recover alleged losses incurred by the Company relating to the invoicing matter and to the Ohio public retirement plans matter.</span></div><div style="line-height:120%;padding-top:4px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;color:#000000;font-style:italic;font-weight:bold;text-decoration:none;">Income Taxes</span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">In determining our provision for income taxes, we make certain judgments and interpretations with respect to tax laws in jurisdictions in which we have business operations. Because of the complex nature of these laws, in the normal course of our business, we are subject to challenges from U.S. and non-U.S. income tax authorities regarding the amount of income taxes due. These challenges may result in adjustments to the timing or amount of taxable income or deductions </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">or the allocation of taxable income among tax jurisdictions. We recognize a tax benefit when it is more likely than not that our position will result in a tax deduction or credit. Unrecognized tax benefits of approximately </span><span style="font-family:Arial;font-size:10pt;"><span>$149 million</span></span><span style="font-family:Arial;font-size:10pt;"> as of </span><span style="font-family:Arial;font-size:10pt;">December 31, 2019</span><span style="font-family:Arial;font-size:10pt;"> </span><span style="font-family:Arial;font-size:10pt;"> </span><span style="font-family:Arial;font-size:10pt;">increased from </span><span style="font-family:Arial;font-size:10pt;"><span>$108 million</span></span><span style="font-family:Arial;font-size:10pt;"> as of </span><span style="font-family:Arial;font-size:10pt;">December 31, 2018</span><span style="font-family:Arial;font-size:10pt;">. </span></div><div style="line-height:120%;padding-top:4px;text-align:justify;text-indent:30px;font-size:10pt;"><span style="font-family:Arial;font-size:10pt;">We are presently under audit by a number of tax authorities, and the Internal Revenue Service is currently reviewing our U.S. income tax returns for the tax years 2017 and 2018. The earliest tax year open to examination in jurisdictions where we have material operations is 2012. Management believes that we have sufficiently accrued liabilities as of </span><span style="font-family:Arial;font-size:10pt;">December 31, 2019</span><span style="font-family:Arial;font-size:10pt;"> for potential tax exposures.</span></div>
