Luis Carlos Sarmiento Gutierrez - President
Good morning, and thank you all for joining our fourth quarter 2021 conference call. It is my pleasure to share with you our strong financial results for the year 2021. I am proud to report that during 2021, in the backdrop of a country with very strong economic recovery, we at Grupo Aval achieved the highest net income in the company's history. It has been 2 years since the lockdowns caused by the pandemic began. Since, we believe we successfully managed the crisis appropriately, addressing risk management and commercial issues, supporting our customers and caring for our employees. We further believe that our handling of the prices, coupled with our diversification strategy resulted in the manageable volatility in our results, especially when compared to our peers.
In Aval, during 2022, things have progressively gone back to normal. Among the most important changes to our customary way of working, we have migrated to a hybrid work scheme, presencial/remote, which will remain our standard going forward. We are now much more mindful of the benefits of such working standard, which we believe, when applied wisely, results both in employee satisfaction and operating efficiencies. 2022 will also result in a material change to our ownership structure as we execute the spin off of 75% of BAC Holding International Corp, BHI, the holding company which owns our Central American banking group. More on that later in the call.
And now before we jump into the detail of our financial results, I will refer to the economic performances of the countries in which we operate. I will provide a brief update on the status of our clients' pandemic-driven loan reliefs, of our digital initiatives, of our ESG efforts, and as I said before, I will also update you on our progress regarding the spin off.
Around the world, 2021 was a year of economic transition,, with countries experiencing a rebound in their business activity, domestic consumption and a marked acceleration in their inflation indicators. According to the IMF, global GDP in 2021 would have grown 5.9% in 2021 after the 3.1% contraction evidenced in 2020. For 2022, the IMF forecasts a GDP growth of 4.4%, despite the Ukraine-Russia conflict that has already adversely affected growth prospects in Europe and developed countries. Specifically, during 2021, the Colombian economy recovered and surpassed, in most instances, the production levels lost during the sanitary crisis with one notable exception: unemployment. Additionally, as in most economies around the world, the recovery has not been devoid of inflationary pressures. In fact, Colombia's economy grew 10.6%, the highest rate in Colombia's history. During the last quarter, GDP expanded at 4.3%, above the market consensus of 2.6%. This result is mainly explained by a rebound in private consumption that grew 14.6% versus 2020 and 8.9% versus 2019.
The recovery in domestic demand reflects the use of excess savings by households, a significant increase in remittances from abroad, the fiscal stimulus put in place during the pandemic and a partial recovery in the labor market. From the supply side, growth in the last quarter was driven by commercial activities and manufacturing that grew 4.6% and 2%, respectively, and represent 30.3% of GDP. Construction and government services representing 19.7% of GDP, grew 4.3% and 1%, respectively.
Regarding COVID vaccinations, at year-end 2021, 55.7% of Colombia's population had a complete vaccination schedule. In Central America, approximately 50% of the population has a complete vaccination schedule. Costa Rica leads with 75% and Guatemala lags at 32%. This has allowed Colombia and Central America to reestablish pre-pandemic production at a relatively good pace. However, 2022 is not free of other challenges.
As you know, this is an election year in Colombia and the contractionary monetary policy currently in effect will no doubt affect the growth momentum. It remains to be seen how profound the impacts of these challenges are. Despite these challenges, 2022 also brings the opportunity to further normalize cost of risk to strongly grow the loan portfolios and in theory to expand interest margins, at least initially in our majority commercial loan portfolio banks. In addition, the unexpectedly higher oil prices boost export revenues and provide some relief to Colombia's twin deficits. All in all, we currently expect 2022 Colombian GDP growth to be in the 4% to 4.5% range. This is in the lower side of market consensus and lower than the government forecast of 5%.
The exchange rate registered material volatility during 2021, ranging between COP 3,421 per dollar and COP 4,024 per dollar, closing at COP 3,981 per dollar, on average, a devaluation of 15.98%, mainly as a result of the global strengthening of the U.S. dollar due to the expectation of an early reduction of monetary stimulus by the Federal Reserve and the increase in local country risk premium due to the partial loss of investment grade.
However, during the last few days, the peso has strengthened below COP 3,800 per dollar in response to the surge in oil prices due to the expected shortage of supply in the upcoming months. I must note that the Ukraine-Russia conflict implies an increase in the value of cereal and fertilizer imports, which will no doubt pass a toll on the Colombian trade belts. We currently expect some volatility of the exchange rate around the COP 3,850 per dollar level during the remainder of the year.
Inflation closed the year at 5.62%, up from 1.61% in 2020. On a 12-month basis, at the end of February, inflation reached a 6-year high of 8.01%, mainly driven by supply factors affecting particularly the agricultural sector. In fact, food prices increased a record high of 23.3% in annual terms. As monetary policy starts to anchor inflation expectations, we expect 12-month inflation to slowly come down to 5.5% by the end of the year, above the Central Bank's target of between 2% and 4%. We will remain observant, however, of additional inflationary pressures derived from the Ukraine-Russia conflict and its effects on commodity prices in the international markets.
After keeping the repo rates stable during the first 9 months of the year, the Central Bank, once it became evident that inflation was accelerating, increased the inflation rate 125 basis points between September and December 2021, from 1.75% to 3%. The repo rate is currently at 4% after a 100 basis point hike during the last meeting in January.
As the inflationary pressures lingered throughout 2022, an accelerated cycle of increases in the repo rate is foreseeable. In fact, we now anticipate that the repo rate could reach 6% by the first half of 2022 and 7% by the end of the year. Although the labor market has lagged, it has also continued to improve. After an average national unemployment rate of 13.7% at the end of 2021, down from 16.1% in 2020, it still did not reach the pre-pandemic level of 10.5% achieved in 2019. As the recovery process continues, we expect a further decline in the unemployment rate to an average of 12% in 2022.
The current account deficit widened to 5.7% of GDP in 2021, mainly driven by a greater imbalance in the trade balance that reached a deficit of $20.5 billion in 2021 due to a much faster growth in imports, reflecting stronger domestic demand and a more modest growth in exports. The widening of the current account was financed 53% by foreign direct investment and by portfolio inflows as the appetite by foreigners for domestic public bonds in the local market resumed during the second half of last year. Going forward, external accounts should improve mainly because of oil prices and better crude and coal production levels. However, rising prices of imported goods affected by the Ukraine-Russia conflict could dampen this improvement. Despite the expected surge in oil and coal exports, the current account deficit is expected to hover around 4.8% in 2022.
On the fiscal front, the fiscal deficit for 2021 was 7.1% of GDP, lower than the 8.6% expected by the government. This was a result of higher economic growth, better tax collection and lower execution of the government's spending budget. Even though the government managed to push through a tax reform amid a complex political environment, Colombia's credit rating was downgraded by the rating agencies, which had an adverse effect on the country's risk premium and on the ratings and yields of Colombian issuers. For 2022, the government expects a further decline of the fiscal deficit to 6.2% based on the ongoing economic recovery and additional revenues from the oil sector.
We move on to Central America. During 2021, the region benefited mainly from the economic recovery of the United States and the positive implications in trade and remittances. As a result, after a contraction of 7.7% in 2020, the IMF projects real GDP growth of 6.8% for the region in 2021, with the highest growth in Panama, 12%; in El Salvador, 9%; followed by Guatemala, 5.5%; Nicaragua, 5%; Honduras, 4.9%; and Costa Rica, 3.9%. For 2022, GDP growth for the region is expected to be 4.2%, slightly above the annual average of 4% registered between 2010 and 2019. The Central American countries are predominantly oil importers. The increase in oil prices and the disruption in global supply chains have pressured inflation and will most likely continue to pressure inflation in the region.
During 2021, Nicaragua, Honduras and El Salvador were the most affected with inflations of 7.2%, 5.3% and 6.1%, respectively. Costa Rica and Guatemala registered inflations of 3.3% and 3.1%, respectively, while Panama registered 2.6% inflation. As of December, we had COP 21.6 trillion in active reliefs or under structural agreements, representing approximately 9.5% of our total consolidated loan portfolio. In Colombia, active reliefs amounted to COP 7.4 trillion or 5.3% of the Colombian loan portfolio. And in Central America, relief amounted to COP 14.3 trillion, representing 16.1% of the region's portfolio.
Panama accounted for approximately 49% of the region's active reliefs. Of all loans that have concluded their relief periods, those currently past due 90 days or more, represent approximately 1% of our total consolidated loan portfolio, while those currently past due 30 days or more represent 1.6% of our total consolidated loan portfolio.
If we move on to digital, these are some numbers that back up the execution of our strategy during 2021. In Colombia, active digital clients totaled 3.8 million, approximately 44% more than 12 months ago. Our banks sold 1.5 million digital products during 2021, an increase of 59% versus 2020. 60% of all sales of retail products for which a digitalized solution has been developed were conducted digitally.
Our recently improved mobile banking apps reached 1 million downloads in both Android and iOS. Transactions conducted through Aval's closed payment gateway, AvalPay Center, increased 122% versus 2020. Campaigns using advanced analytics developed, based on our unified database platform, Augusta, have been able to increase effective disbursements by 40%. Mathilde, our programmatic ad platform, has allowed us to reduce by 41% or cost per 1,000 impressions. In Central America, digital clients increased 20% during the year, reaching almost 2 million clients at year-end.
Digital sales increased 41% versus 2020 through 37 digital products. PFM, or personal finance management, a personal finance solutions app that helps our customers understand their finances and make better decisions was successfully launched. Kash, our transactional app, despite being relatively recent, was one of the most downloaded apps in the region.
Let's move on to ESG. In the past decade, ESG has become an integral part of our strategy. Alongside our subsidiaries, we're firmly committed to becoming better at it every year that passes by continually raising our standards of environmental protection by striving to improve our interactions with all our stakeholders and by pushing for strong corporate governance.
These are a few of our ESG milestones during 2021. On corporate governance and risk management, after having implemented ESRA, Environmental and Social Risk Analysis systems on Banco de Bogota back in Multibank, we began to roll out to our other Colombian banks. On the economic performance front, Corficolombiana issued a COP 500 billion social bond. In addition, our banks launched green products and sustainable development credit lines. Among the most important, the Amazonia card in Banco de Bogota, the UNICEF card in Banco de Occidente, sustainable housing and electric vehicle lines and others.
Regarding corporate efficiencies, we adhere to the United Nations Global Compact, reaffirming our commitment to the sustainable development goals. Through Ecobot machines, we carried on recycling initiatives, recycling approximately 0.5 million plastic bottles. On talent management, we developed our corporate diversity and inclusion policy. Banco de Bogota, Occidente, Popular and Porvenir received the Great Place to Work certifications. We migrated to a hybrid presencial/remote work scheme that will be our standard going forward, maintaining an exclusively remote work scheme for some positions.
Finally, regarding the social and environmental initiatives. Banco de Bogota and Corficolombiana became part of the Dow Jones Sustainability Index. Banco de Bogota is among the top 8 most sustainable banks. We implemented, through our subsidiaries, environmental initiatives, including the reforestation of the Amazon and the use of renewable energies in some of our branches and headquarters. Finally, our subsidiaries, jointly with our controlling shareholder, fully funded the construction of a $500 million state-of-the-art cancer treatment and research center in Colombia, which is currently being staffed and equipped and is scheduled to open its doors to patients in the second quarter of this year.
As you recall, during September of 2021, Banco de Bogota informed the market of its intention to spin off to its shareholders, including Grupo Aval, 75% of the shares the bank currently owns of BAC Holding International Corporation, BHI, the holding company that ultimately owns 100% of the shares of our Central American banking group, BAC Credomatic. Concurrently, Grupo Aval informed the market of its intention to spin off to its shareholders the shares of BHI received as a result of the mentioned Banco de Bogota spin off.
There are several reasons behind these transactions. On the one hand, as a consequence of BAC's excellent financial performance since we acquired it in 2010, accentuated in most years by the Colombian peso natural devaluation against the U.S. dollar, BAC is currently almost the same size as its owner, Banco de Bogota. In this regard, we do not consider convenient that Banco de Bogota owns another bank of equal size. Additionally, the transaction will strengthen Aval's and Banco de Bogota's strategic focus on Colombia, because as a result of the spin off and the deconsolidation of this investment in our numbers, we will simplify our corporate structure, eliminate multi-jurisdictional complexities and increase our agility and flexibility to respond to the dynamics of the local markets in which we operate.
We also expect to gain flexibility in the administration of regulatory capital as we continue to move towards full Basel III principles. This, in turn, should allow us to improve our strategic position to capture future growth.
Lastly, we hope, although obviously cannot guarantee, to unlock some value for our shareholders. As anybody that follows our shares knows, the multiples at which our shares trade with respect to the company's earnings are comparatively depressed and have been so for a while when compared to those of our peers. In fact, an independent valuation determined that Aval's share value after the spin off would have a price similar to the price at which it trades today.
Under that scenario, Aval's price multiples to earnings would be fairly comparable to those of our peers. BHI's shares will trade in the Colombian Stock Exchange, along with the shares of Banco de Bogota and Grupo Aval. BHI will also trade in the Panamanian Stock Exchange. Therefore, we expect that the stock will be marketable and liquid. As of yesterday, this transaction has received all the required regulatory approvals. And therefore, we will now proceed with the execution stage. Our intention is to close the spin-offs and deliver the BHI shares to the eligible shareholders by the end of March. If that is the case, our financial statements at the end of this quarter will cease to consolidate BHI and any income derived from the 25% investment at Banco de Bogota while retaining BHI will be accounted for via the equity method.
Finally, we also expect to book extraordinary net income from the realization of certain OCI accounts at Banco de Bogota as a byproduct of deconsolidation. We will have a better idea of that extraordinary net income among -- the amount the day of the spin off.
As Diego will explain, the spin off should boost Banco de Bogota's regulatory capital by approximately 130 basis points. However, to further boost this ratio and to absorb other changes to regulatory capital derived from the progressive adoption of Basel III principles, Banco de Bogota's Board will propose to its shareholders to not declare a cash dividend in the upcoming shareholders' meeting. Aval will follow suit as it is the company's unwritten custom to declare dividends in the same amount as it receives from its subsidiaries.
Regarding our financial results, Diego will refer next in detail to our financial performance during 2021. However, I would highlight the following: our banking subsidiaries successfully rode the wave of the country's economic rebounds that improved the credit profile of our customers, presented growth opportunities, lowered the cost of risk and increased recoveries of written out loans.
As a result, we achieved net income of COP 3.3 billion, 40.4% higher than in 2020 and 9% higher than in 2019. This marks 2021 as the year with the highest net income in our history. Return on average equity was 15.3% and return on average assets was 1.65%. At year-end, versus 2020, consolidated assets grew by 13.6%. Consolidated gross loans grew by 13.2%; 30- and 90-day PDLs indicators improved by 86 and 66 basis points, respectively, versus 2020. Cost of risk improved by 110 basis points. Net fee income for the year increased by approximately 10%. Our cost to assets improved by 10 basis points, and our funding and liquidity positions remained strong. I thank you for your attention, and now I'll pass on the presentation to Diego, who will explain in detail our business results and provide guidance for 2022. I will add that the guidance that Diego provides for 2022 will be devoid -- will not include the extraordinary net income that will result as a consequence of the spin off. I thank you for your attention once again. And Diego, please continue.
Diego Fernando Solano Saravia - CFO
Thank you, Luis Carlos. I will now move to the consolidated results of Grupo Aval under IFRS. Starting on Page 11. Assets grew 13.6% during 2021 and 4.3% during the quarter. Excluding the FX movements of our Central American operation, total assets grew 7.6% during the year and 2.7% during the quarter. Our assets grew 9.3% for the year in Colombia and 4.8% in dollar terms in Central America. 16% depreciation over the last 12 months resulted in a 21.8% annual growth in Colombian pesos of Central America. Quarterly growth was 2.1% in Colombia and 3.5% in dollar terms in Central America. A 4.9% depreciation during the quarter resulted in an 8.3% growth of Central America in Colombian pesos. The weight of Central America reached 37% of our book, with BHI and MFH (sic) [MFG] accounting for 32% and 5%, respectively.
Moving to Page 12. Loans grew 13.2% over the year and 4.3% during the quarter. Our Colombian gross loan portfolio grew 6.6% over the year and 2.2% during the quarter, partly performance in Colombia reflected a strong dynamic in retail lending and still soft one in commercial lending, similar to the trends of the banking system.
Demand for consumer loans in Colombia continued to be strong, resulting in a 3.2% growth during the quarter and 11.5% for the full year. 12-month growth remained driven by payroll loans, with a 15.7% increase while our quarterly growth included a strong performance of unsecured products. During the year, automobile loans grew 9.8%; personal loans, 6.1%; and credit cards, 2.2%. Payroll lending and auto financing, our main consumer secured products, were 2.3% and 5.2%, respectively, during the quarter. These products account for 61% and 7% of our Colombian consumer portfolio. Both personal loans and credit cards, which account for 20% and 12% of our Colombian consumer portfolio, grew at 4.3% during the quarter.
As other secured retail products, mortgages remain dynamic, expanding 4.7% over the quarter and 15% year-on-year. On the other hand, corporate lending growth in Colombia continued to be weak. Commercial loan portfolio, excluding repos, grew 1.2% (sic) [1.3%] over the quarter, taking annual growth to 2.9%. In addition to market trends, our growth is affected by a disciplined pricing approach that focuses on profitable growth.
Moving forward, business confidence in Colombia and the positive trends in economic activity support a strong commercial loan growth rate. In addition, we expect that retail lending momentum will persist as employment continues its recovery and household demand consolidates, allowing banks to extend further into higher-risk products. We have a positive view on 2022 growth despite temporary headwinds in confidence during the first half of this year derived from the election cycle and the uncertainty associated with the global geopolitical events.
Moving to Central America. Our gross loan portfolio increased 8.3% in dollar terms year-on-year and 3.2% over the quarter.
Quarterly performance in Central America evidenced a recovery in economic activity that resulted in 3.9% and 3.7% growth in consumer and commercial loans, respectively. Mortgages increased by 1.1% over the quarter.
On Pages 13 and 14, we present several loan portfolio quality ratios. Cost of risk has returned to a recurring pre-pandemic levels. COR receded earlier than expected due to a favorable evolution of the behavior of relief customers returning to regular payment schedules and a fast and strong rebound of the economy. This improvement reflects in a better composition of our loan portfolio measured by loans classified by states.
Relief programs were successful in allowing us to manage the COVID-19 shock with lower impact on our consumers and thus impairment losses than what was expected at the beginning of the pandemic. As of December, 0.8% of our gross -- total gross loans remained under payment holidays and 8.7% under structural payment programs, together accounting for 9.5% of our loan portfolio. In Colombia, 5.3% of our loans have some type of relief; only 0.04% of our Colombian gross loans are still under payment holidays. Most reliefs are structural payment programs under the PAD, the government-sponsored borrower support program.
In Central America, 16.1% of our loans still have some type of relief. This is broken down into 14.1% of gross loans under structural payment programs and 2% under payment holidays. The payment holidays that remain are concentrated in Panama. That accounts for 85 -- 88% of those. The outstanding balance of payment holidays in the region contracted 41% over the quarter down to $443 million. At the end of period, 4.3% of our total loans that in the past had benefited either from payment holidays or were restructured and that had returned to active payment schedules were past due more than 90 days. These past due loans continue representing 1% of our total gross loans. And these numbers are 6.9% and 1.6% for loans past due more than 30 days.
In Colombia, 6.7% of loans previously relieved that had resumed active payment schedules, were 90 days past due, representing 1% of gross loans. For 30 days PDLs, these numbers were 9.3% and 1.4%. In Central America, 2.7% of loans previously relieved that had returned to active payment schedulers were 90 days past due, representing 0.9% of gross loans. For 30 days PDLs, these numbers were 5.3% and 1.8%, respectively. So significant development evidencing the recovery after the pandemic.
PDL formation has returned to pre-pandemic levels. As reported in our last call, third quarter PDL formation benefited from over COP 580 billion of AviancaTaca group loans returning to current. Regarding delinquencies, metrics for 30 days and 90 days PDLs continued improving during the quarter. Our allowance coverage of 30-day PDLs and 90-day PDLs also improved over the quarter. The quality of our loan portfolio improved relative to a quarter and a year ago. 30 day fell to 4.04%, a 36 basis point improvement over 3 months and 86 basis points improvement over 12 months. 90-day PDLs fell to 2.9%, a 20 basis points improvement over 3 months and 66 basis points improvement over 12 months.
Even though not yet to pre-pandemic levels, the breakdown of our loan portfolio by stages continues to improve, with Stage 1 loans gaining 91 basis points in the mix, compensated by 72 basis points and 19 basis points decrease in Stage 2 and Stage 3 loans. This improvement was mainly driven by our consumer loan portfolio in both geographies, which recorded 138 basis points increase in share of Stage 1 loans to 83% and 102 basis points decrease in Stage 2 to 12.8%. The higher-than-normal level of Stage 2 loans will linger for several quarters, but is expected to move -- to improve as previously relieved customers maintain a healthy payment behavior throughout this year or fully pay their outstanding balances.
We expect this behavior to materialize and support our positive view on the evolution of cost of risk during 2022. 2021 cost of risk, net of recoveries was 1.9%, in line with our previous guidance. This result incorporates a 28 basis points increase in cost of risk of our total portfolio over the quarter, with 64 basis points increase in commercial and 15 basis points improvement in retail. Quarterly cost of risk increased 45 basis points in Colombia, driven by commercial loans, and remained flat in Central America.
Finally, the ratio of charge-offs to average 90-day PDLs was 0.7 percent times for 2021 and for the quarter.
On Page 15, we present funding and deposit evolution. Funding growth during the quarter reflects a still high liquidity environment. As a result, our deposit to net loans ratio remained high at 106%, while our cash to deposits ended the quarter at 15.6%. Our funding structure remained relatively stable with deposits accounting for most of our funding at 76%. Deposits increased 10.7% year-on-year and 4.1% during the quarter. Colombia grew 1.5% during the quarter, while Central America grew 3.2% in dollar terms. Over the 12-month period, Colombia grew 2.6% and Central America, 7% in dollar terms.
On Page 16, we present the evolution of our total capitalization, our attributable shareholders' equity and the capital adequacy ratio of our banks. Both our total equity and attributable equity grew 11.4% over the year, mainly driven by our earnings. Total equity increased 2.8% during the quarter, while attributable equity increased 3%. As of fourth quarter 2021, our banks show a [profit in] Tier 1 and total solvency ratios. Moving forward, we estimate that the spin off described by Luis Carlos, will have a positive impact of close to 130 basis points in Banco de Bogota's capitalization ratios.
Two forces will improve the capitalization of Banco de Bogota: first, the deconsolidation of $20 billion or 46% of Banco de Bogota's risk-weighted assets; and second, Banco de Bogota will cease to deduct $1.6 billion in goodwill and intangibles from its core equity Tier 1. On the other hand, some negative elements result from the spin off. First, $2.6 billion or 36% of Banco de Bogota's equity, will be spun off; second, the bank will deduct $0.5 billion from its core equity Tier 1 associated with its remaining 25% minority interest in BHI; and third, Banco de Bogota will no longer benefit from the $520 million AT1 issued by BAC International Bank in 2020.
However, despite this positive effect, we expect Banco de Bogota's first quarter 2022 capitalization ratios to be similar to those reported for year-end 2021. The depreciation of fixed income markets has led to unrealized losses to our OCI, reducing core equity Tier 1. In addition, the adoption of Basel III, including changes in operational risk during this quarter, is expected to increase risk-weighted assets. To further strengthen Banco de Bogota's and Grupo Aval's capital basis, their Board of Directors will recommend to their respective shareholders' meetings to be held in the upcoming weeks that neither Banco de Bogota nor Grupo Aval distribute cash dividends related to 2021's net income.
These recommendations seek to, on the one hand, prime Banco de Bogota's capital base to capture growth potential during the upcoming years. And as far as Grupo Aval is concerned, the recommendation falls largely in line with Aval's custom to not distribute dividends unless it's paid dividends by its affiliates. In recent years, Aval and Banco de Bogota have distributed, on average, close to 50% of their annual net income.
On Page 17, we present our yield on loans, cost of funds, spreads and NIM. 2021 interest rate behavior was driven by a falling average reference rate. Growth focused on lower risk, lower return products and segments during most of the year and by the increase in price competition on those. The annual average Central Bank rate in Colombia contracted 95 basis points to 1.92% in 2021, while the average 3-month LIBOR contracted 49 basis points to 0.16%. These changes negatively impacted yields in both regions during the year. In this environment, 2021 yield on loans fell 98 basis points down to 8.37%. The spread between average yield on gross loans and the average cost of funds contracted 28 basis points to 5.98% despite a 71 basis points reduction in cost of funds down to 2.39%.
Despite an increase in rates during the quarter, the average yield on loans of 8.46% and the average cost of funds of 2.51% for fourth quarter, still were 20 basis points and 5 basis points lower than a year earlier. As a result of these trends, our annual net interest margin contracted 36 basis points to 4.8%, driven by a 17 basis point decrease in net interest margin on loans to 5.8% and a 64 basis point decrease in net interest margin and investments to 0.9%. Quarterly NIM fell 12 basis points quarter-on-quarter, driven by a 37 basis points contraction of NIM on investments and of 7 basis points in NIM on loans.
NIM on loans remained stable in Colombia during 2021 at 5.6% and fell 53 basis points to 6.1% in Central America. The variation in Central America resulted from a slight contraction in BHI and the effect of the full year versus 7 months in 2020 of MFG. MFG has tighter net interest margins given that it operates in Panama only. We expect that the rising interest rate cycle can provide an upside for higher NIM on loans with an initial temporary downward pressure given the accelerated pace at which it is happening and in repricing timing differences between assets and liabilities. Price competition, given the positive macro outlook, could also delay such improvement. Net interest margin on investments will be under pressure in this environment and could be affected by global monetary policies and geopolitical events.
On Page 18, we present net fees and other income. Gross fee income for the year reflects a pickup in banking services and debit and credit card fees as lockdowns receded and transactional activity recovered to pre-pandemic levels. 2021 consolidated gross fees increased 10.6%, resulting from an 8.7% growth in Colombia and a 10.9% growth in dollar terms in Central America.
Gross fees increased 4.4% quarter-on-quarter in Colombia and 13.1% in dollar terms in Central America. The recovery of consumer activity added to the high seasonal behavior of fourth quarter, yielding this strong result. Income of the -- from the nonfinancial sector was strong during 2021. Our infrastructure sector, that is the largest contributor to our nonfinancial income, grew 15.7% in 2021. Energy and gas companies decreased their contribution to our nonfinancial sector by 6.9%, given a high comparison base in 2020 from Promigas' companies in Peru.
Finally, although historically a low contributor to our nonfinancial sector, our hospitality business has a positive result during the second half of the year as occupancy rates rose. Despite this improvement, its annual result was a COP 14 billion loss.
Finally, on the bottom of the page, other income was lower than a year earlier. Other income included optimization strategies executed during the fourth quarter of 2020, and income from nonconsolidated investments increased due to the recovery in equity method from Promigas' associates and a COP 45 billion extraordinary dividend from Grupo Energia de Bogota during the third quarter of 2021.
On Page 19, we present some efficiency ratios. All our business units continued implementing cost efficient initiatives during 2021. Cost to assets for 2021 was 3.3%, down from 3.4% in 2020. Cost to income was 47.6%, up from 46% a year earlier and stable relative to 2019. Cost to income was affected by a 36 basis points contraction in NIM and a 10.5% decrease in other income from operations given the high comparison base in 2020. Other expenses increased 7% year-on-year, with Colombia growing 5.6%, in line with inflation, and Central America at 6.9% in dollar terms. The latter was impacted by 5 additional months of consolidation of MFG. Without the effect of MFG, other expenses would have increased 6% for Aval and 4.8% in dollar terms in Central America. Personnel expenses grew 2.6% in 2021 with Colombia growing 3.9%; and Central America, 1% in dollar terms. General and administrative expenses increased 10.1% in 2021. General and administrative expenses increased 4.7% in Colombia and 15.6% in dollar terms in Central America. The increase in Central America is tied to expenses associated with the recovery in fee income and to increased marketing expenses. Depreciation and amortization were 1.5% year-on-year. Depreciation and amortization increased 0.2% in Colombia and 1% in dollar terms in Central America.
Finally, on Page 20, we present our net income and profitability ratios. Attributable net income for 2021 was COP 3.298 trillion or COP 148 per share, 40.4% higher than the result for 2020. Attributable net income for the quarter was COP 777 billion or COP 34.9 per share. Our return on average assets and return on average equity for the year were 1.6% and 15.3%, respectively. These ratios were 1.4% and 13.7% for fourth quarter.
Before moving to the questions and answers, I will now summarize our general guidance for 2022. Given that we expect to complete the spin off of 75% of BHI shortly and cease to consolidate BHI, starting this call, our guidance will refer to our continued operations. We expect loan growth from our continued operations to be in the 14% area with commercial loans growing in the 12% area and retail loans in the 16% area. We expect our cost of risk, net of recoveries, to be in the 1.6% area. We expect full year NIM to be in the 4.3% to 4.5% range with NIM on loans between 5.4% and 5.6%, benefiting from a slight positive effect from the rising interest rate scenario.
We expect cost to assets to be close to the 2.6% area or a 20 basis point improvement versus the comparable metric in 2021. We expect our fee income ratio to be in the 15% to 17% range. We expect our nonfinancial sector to contract 25% relative to 2021's. Finally, we expect our return on average equity of our continued operations to be in the 15% area.
Regarding BHI that will no longer be consolidated by Aval after the spin off, we provide the following guidance in dollar terms. We expect loan growth to be in the 7% area with commercial loans growing in the 10% area; in retail, in the 6% area. We expect cost of risk net of recoveries to be in the 1.9% area. We expect full year NIM to be in the 5.8% to 6% range with NIM on loans between 6.7% and 6.9%. We expect cost to assets to be in the 4.3% area. We expect fee income ratio to be in the 30% to 32% range. Finally, we expect the return on average equity of BHI to be in the 13% area. With this, we are now available to address your questions.

(Operator Instructions) We have a question from Juan Recalde from Scotiabank.
Juan Ignacio Recalde - Associate
My question is related to the potential capital raise. In a previous call, you had mentioned that the -- that it was an option to raise capital at Banco de Bogota. So now you have mentioned that there is not going to be a dividend payment. Would that be enough? Or is the capital raise still on the -- is still an option?
Luis Carlos Sarmiento Gutierrez - President
Thank you, Juan, for your question. Well, yes, as you mentioned yourself, proxy for raising capital is obviously not distributing dividends, and that's what we're doing. What we've noted so far, as we mentioned in the call, is that the spin off by itself will raise Banco de Bogota capital ratios by about 130 basis points. And obviously, there will be a further positive by not distributing dividends. With all that in mind, there really should not be a need for any capital raises.
But that does not mean that if we see the bank growing the way we expect it to, we might later on in the year, consider an additional capitalization. But for now, as I said, with the actions that we've taken we -- there's absolutely no need for capital at the Bank or at Grupo Aval.

The next question comes from Yuri Fernandes from JPMorgan.
Yuri R. Fernandes - Analyst
I have a first question regarding the reliefs on your asset quality. And asset quality from you was a good highlight, like on the consolidated entity, the improvement we saw on 30 days past due loans and the 90 days. So asset quality was good in the quarter, but when you were explaining the reliefs during the presentation, I got that 9.5% of your total loans, they are still in the relief. I guess, in the previous quarter, this number was 9.8%. So when we plotted this on your nominal balance, we see the relief book mostly stable quarter-over-quarter. So my question is, is this really the case?
Like the amortization, it's kind of decelerating on the reliefs? I don't know if that's true and maybe this is driven by Central America, but I want to check this information.
And also the asset quality for the reliefs, I got here, 1% of your total loans, they are on relief. They are past due. This is about maybe 10% on the total loans under relief, right? If you take 1% of your total loans that are due, we are getting about 10% 90 days NPL ratio for the reliefs. And if you plot this for the 30 days, this is something around like 50%, 60%. So all in all, I just want to check the reliefs, like if you can provide more color or explain a little bit better what is happening with the amortization, with the asset quality? I guess that would be interesting.
And if I may, a second question regarding growth. I get here on your guidance for Colombia, a 14% loan growth, right? This for me seems to be ahead of the market. And you mentioned many times on your presentation, compression on spreads, some more competition. So my question is, is Aval maybe -- Aval banks getting more aggressive in regaining market share? And maybe this is the reason for news?
Or do you see this competition speaks more to other players and not Aval banks? Like I'm just trying to understand what is your strategy for price? Your strategy for spreads and rates? And if you are planning to kind of regain market share and to regain market share, you will be more aggressive on price?
Diego Fernando Solano Saravia - CFO
Well, very good questions you have. I wrote down 3 different questions. The first one regarding the mechanics of the reliefs and how the numbers should evolve. The reason why you should expect to continue seeing the number for reliefs to be relatively stable though falling in time, is that anything that was relieved regardless that it is paying or not, we have marks on. Particularly for the part of the portfolio that was under the PAD -- the government-sponsored borrower support program, we continue to market in this category.
So to try to bring numbers down, out of that 9.5%, around 0.8% of our gross loans is what remains under payment holidays, and that includes mainly what comes from Panama in Central America. In the case of Colombia, the number is 0.04%. So you're talking a very, very slim numbers. So in that sense, you could say that reliefs are over, except for the Panamanian ones that are falling very fast -- around half of those reliefs went away during just the quarter. But part of those goes to something structural, and that's what we continue reporting and continued tracking.
As a matter of fact, part of what we did at the end of the year was we increased -- we included some overlays on part of these loans that had been relieved at some point in time and that yet needed to prove that they would return to normal.
So trying to give you an idea of what we expect into the future, we should see that number trending down. However, until these loans go back to fully normal -- fully normal means over a year of experiencing the proper payment performance or being paid out, will you start to see those numbers falling. So that is something that should be happening later on during the year.
And it was not your question, but to give you some additional color, that's the reason why our guidance on cost of risk for the full year is lower than what we already gave for the last quarter of last year. And it is that we expect to see a positive evolution as those loans actually demonstrate that they are back to normal. So that was question number one regarding what to expect from reliefs and to try to match that to the rest of the behavior.
Then regarding loan growth, we've picked up the number on loan growth, bringing into consideration 2 things: the first one is we've seen inflation picking up. So part of what brings this number higher is also our view on a higher inflation that Luis Carlos mentioned before. So in real terms, this is not as large as a change to what we -- our view was previously.
Then the second piece is you're absolutely on the spot. We have an aspiration and that ties to the Banco de Bogota or the BHI spin off to see recovery in market share that our banks gave away, and that's built into our numbers and built into our strategy. What are we thinking regarding that?
It's a combination of 2 things: one, what the bank has to do internally, and it ties into a stronger commercial activity and other changes in the way they approach the market. And then part of what has slowed us down in the, let's say, the latter part of last year was aggressive pricing in the market that in our pricing models was not profitable growth. To say it in other words, those were businesses that in our numbers might be losing money in the long term. However, with the behavior that we're seeing from the economy this year and the dynamics in the market, we expect to see pricing to return to more reasonable levels. So it's a combination of things that we're doing internally with how we see the market evolving.
Then spread-wise, that's perhaps the toughest question of all because we are seeing the Central Bank raising rates very fast under a normal scenario where this would be a progressive process where rates were going on -- up slowly. We would have a chance to catch up between assets and liabilities and get a benefit on NIM in the short term. That's what we expect to see in the longer term and it is to see our spreads on loans to expand due to a higher interest rate environment. However, the speed does determine what happens in the short term, the repricing differences between assets and liabilities might put some pressure initially.
And finally, we mentioned competition around a stronger Colombian economy. Pricing also includes cost of risk, it's implicit in how we price our loans. So a better view on provisions is also built into NIM. That's the way we look at these numbers is NIM after cost of risk is a good way to think about how these numbers will be evolving. And in that sense, the combination of those 2 should have a positive effect regardless of the sort of growth that we've pointed to.

Our next question comes from Nicolas Riva from Bank of America.
Nicolas Alejandro Riva - VP in Credit Research & Research Analyst
I have 3 questions. The first one on the 2022 bond. If you can discuss how you plan to finance the $1 billion maturity in September?
Second question on the spin off. So then you said you see no need to raise capital at this moment at either the Banco de Bogota or Aval level. You're not going to pay a dividend at this point. And when you talked about the guidance for the capital ratio, you said 130 basis points positive impact on Banco de Bogota because of the spin off. Does this include all of the impact really from the spin off? So the deconsolidation of the risk-weighted assets, the fact that you will no longer have to pay any goodwill -- all of that is already factored into that assumption or projection?
And then third question on the election. So this year, Colombia has presidential reductions, and we know that Gustavo Petro is ahead in the polls. If you can talk about what Petro has said specifically that he would try to do regarding the banking sector? My concern basically would be higher taxes, and we know that the banks already paid higher taxes than the corporates and also taxes on wealth, the tax on shareholders equity that I know that Colombia has implemented in the past. But also if you can discuss your thoughts regarding the risk of nationalizing pension funds, which I'm sure would have a negative impact on Porvenir. And what's the likelihood that he would be able to do such a thing?
Luis Carlos Sarmiento Gutierrez - President
Okay. Let me start with the first one, which is the 2022 bond, Nicolas. We have the funds in place basically to pay that bond already. Remember, that our strategy when we have taken debt internationally has always been to take the monies that we receive from the issuances of the bonds, and we invest those in turn into our own subsidiaries, those that either do not have access to the international markets or they do, but they would have to borrow at a higher cost than Aval itself. So what we do is that we lend that money to those of our affiliates that are in those positions, and we match the maturities of the loans that we make to them to the maturities of our own bonds.
In this case, we have the monies for the 2022 bonds are either in short-term deposits that we have already liquidated the bonds that -- sorry, the loans that we made to our [stocks] and have received the money and put them into liquidity. And then we have some -- the other part of the money is still out with our affiliates, and they will repay it to us before the maturity in September of the 2022 bond. So that's why the September 2022 bond, as we announced when we were marketing the 2030 bond, the 2022 bond will be paid.
Diego Fernando Solano Saravia - CFO
So regarding your question on does this include all the effects, the answer is yes, it does. And I'm going to try to give you another logic on why the numbers are favorable. The reason why they are -- is when you think of the spin off, you're spinning off 100% of the risk-weighted assets. You're spinning off 75% of total equity. However, you're also spinning off goodwill that is a substantial portion of what is being spun off. So when you think of how much of the equity is being spun off, I mentioned $2.6 billion, that's 36%. But out of those $2.6 billion, $1.6 billion is intangibles. Therefore, what you're actually spinning off is $1 billion in tangible equity from Banco de Bogota. That is around 14% of Banco de Bogota's equity or regulatory equity after you deduct this intangible. So in fact, you're taking away 46% of risk-weighted assets, but you're taking away 14% of tangible equity. So that's the main driver. There's the other elements that I mentioned, particularly 20 -- the 25% of the investment gets deducted as a minority investment in a financial company. Then there's something that is replaceable later on. That does have an impact, and it is the AT1 that we issued at BAC International bank, gets also spun off. Therefore, Banco de Bogota will not benefit from that. So that's the reason why we end up with numbers that are positive. And it is mainly that a big portion of what we're spinning off is intangible equity with the risk-weighted assets.
So back to your question, does this include all the effects? Yes, it does.
Luis Carlos Sarmiento Gutierrez - President
And then your third question regarding Mr. Petro, yes, as you mentioned, he is ahead in the polls. But this past Sunday was a very, very interesting exercise, if you think about it. On the one hand, Petro obtained about 5 million votes on his own primary, if you will. And -- but the interesting thing to contrast with that is that his party only got 2.5 million votes for Congress. So there is a difference -- a substantial difference in the votes that he got himself with regards to the -- or in comparison to the votes he got for his own party.
And that leads us to understanding that the composition of Congress is going to be -- that's always very, very important in his ability to pass laws as always and as it works anywhere else, regarding the points that you mentioned, higher taxes, taxes on wealth, taxes on the banking system and the -- and we'll talk in a second about his mentioning of the nationalization or as he calls it, the democratization of pension funds.
So yes, he's still ahead. And we have to see whether the 5 million votes that he got, one, will repeat in the first round of the presidential elections -- they might. But secondly, remember that we expect between 20 million and 21 million votes for -- in the presidential election.
So there's still a large territory to be covered, and we have to see where the other 16 million votes go. Even if he got all the votes that his coalition got in the primaries last weekend, there's still about 10 million votes that we would have to see where they go in the presidential elections. Now even if he wins, Congress has already been voted on, and it's already been composed. And even though his body got the majority, not -- got more seats selected than the other party, he definitely didn't get the majority of Congress, not even close and not even if you add up those other parties that you think would probably be in coalition with them when they vote in Congress.
So we're still a ways off, Nic, of suffering, if you will, the consequences of what he said regarding higher taxes, taxes on wealth and taxes to the financial system. We'll see. We'll see what Congress votes on that. So we're still a ways from that.
You also mentioned the democratization of -- the nationalization of the pension funds. And obviously, as you said, if that happened, that would have a very large impact on Porvenir and Proteccion and all the other pension funds in the country. And -- but there was a national outcry. I don't know if you followed the news in the last couple of days, but since he came out in the debate and talked about that, and for the first time, he was very straightforward with his intentions, there has been really a national outcry from affiliated people to the pension funds coming out and saying, hey, no, what you said is wrong. Those pension funds, he basically said in the debate, that the pension funds belong to the owners of the pension fund administrators. And as we all know, that is absolutely not true.
So again, yes, is it uncomfortable. Yes, absolutely. I mean there's no doubt about it. Do I think that, that's a done deal? No, I don't think by a stretch of imagination, it's a done deal. I think there's still a lot more that has to happen before those elections, those campaign "promises" become realities.
Operator
Our next question comes from Sebastian Gallego from Ashmore.
Sebastian Gallego
I have several questions. The first one is just a follow-up on capital and the positive effect that you mentioned on 130 basis points on Bogota. I'm wondering if you could clarify the OCI effect that Diego mentioned in the presentation because it seems that the OCI unrealized losses may mitigate the positive effects from the 130 basis points. So that clarification will be nice for the first question.
The second question is also a follow-up on the comments that Mr. Luis Carlos mentioned on capital increase. You mentioned that you probably won't need a capital raise, but it could come later on in this year. We're wondering if excess cash could be an efficient capital allocation at Banco de Bogota. And we're wondering if you're thinking about M&A activity in Colombia to foster growth at Banco de Bogota.
And the third question will be on risk appetite on consumer loans. You provided a guidance of 16% for retail, and we're seeing higher growth on unsecured lending. Can you talk about that? And what could be the strategy on a sustainable basis?
Diego Fernando Solano Saravia - CFO
Yes. Going through your 3 questions. The first one regarding the negatives that are offsetting the positive benefit from the spin off. You mentioned one of those, and you're absolutely right. OCI is something that is moving, and we expect to continue see moving over the remainder of the year as the global interest rate environment picks up and that affects banks either through OCI in our case, where we are concentrated in fair value to OCI or affect banks directly to P&L if you have those as per value to P&L. So either way, it ends up eating capital from banks, and that's a global trend that we see happening, and it also affects Aval.
However, there is a second piece of what I mentioned that perhaps I need to highlight more, and it is part of the transition to Basel III includes changes in operational risk. Starting this year, there's a trigger, and this is one of the last triggers on this transition that will be generating these sort of effects. And it says -- not to get technical, there is some coefficients that are determining what is the translation from operational risk into risk-weighted assets. It's pretty substantial what we expect to see in the Colombian market, and that's why the order of magnitude of the culmination of these 2 effects adds to around 130 basis points or 100 basis points or something on that area.
So you're right on the OCI, not only for Aval, but for all the banks in Colombia and around the world. What is particular about Colombia and all the Colombian banks is this next step in operational risk.
Luis Carlos Sarmiento Gutierrez - President
Regarding the capital increase that you mentioned again in Banco de Bogota, as you say -- well, first, as I said, the numbers have proven that there is no capitalization needed just because of the spin off, as Diego was just saying. But then again, I did mention that if we needed to, we would consider a capitalization in the remaining part of the year. Obviously, as you also mentioned, we wouldn't capitalize just to sit on cash. That would be, as you said, the most inefficient use for capital. We would consider it for growth. And obviously, we would consider a capitalization for M&A.
At this point, we don't have anything particular in mind and -- but we do have growth in mind. And the mindset of the group right now is around growth -- around profitable growth, but around growth. And so if that was the case, and this is all our banks, we are always very, very observant of what happens with growth. And if growth requires capital, then we think that's a very efficient capital need. So yes, that's why I said that for now and just because of the spin off, no capital will be needed, but we would not stop considering a capitalization. We just don't know what amount yet.
Diego Fernando Solano Saravia - CFO
And finally, you had a question on risk appetite, and it was, as I understand it right, are you -- have you raised your risk appetite, and the answer is yes, we have. And yes, we have because we've seen an improvement in performance that we were waiting for to open up to some areas that we had diverted from during the pandemic. To try to be quantitative here, the kind of things that we have already seen is loan formation, past due loan formation is back to pre-pandemic levels. And if you look at that broken down by kind of loan by segment, we are starting to see exactly the same behavior, not only in the aggregate, but also segment by segment.
And then if you think around stages, at this point, Stage 2 is still more than what it used to be pre-pandemic. We are around 11%, 12% of our loans are in Stage 2. The pre-pandemic levels are more in the 5% area. However, when you build in all the overlays and those loans that are categorized as stage 2 -- because they were relieved at some point but are behaving, we see factual evidence that numbers are going back to normal, to pre-pandemic levels, and that allows us to go back to some of those products that are particularly risky in the environment that we lived over the past couple of years.
That's the reason why when you look at our third -- our fourth quarter numbers, you start to see a much higher contribution of credit cards, of personal loans and those sort of loans that we had deemphasized in the past. The same applies to sectors of the commercial loans. There are sectors that were much riskier before that as the market evolves, appear to be much better. And finally, the other number to look at or that we look at is unemployment. Unemployment is improving at a rate of around 200 basis points per annum. We see that continuing into this year, and that brings numbers back to the kind of environment in which we feel comfortable to be, let's say, not more aggressive, but back to our normal appetite. We had gone into a risk averse mode over the past couple of years, and we're back to something that is an Aval standard.
Operator
Our next question comes from Daniel Mora from CrediCorp Capital.
Daniel Mora - Analyst
I have just a couple of questions. The first one is a follow-on on the capital ratios. I would like just to understand with the 130 basis points improvement in capital ratios, that will be reflected in the Stage 1? With the latest figure that you published in the fourth quarter, the Stage 1 of Banco de Bogota has stood at 10.2%. With this 130 improvement, we can reach a figure of 11.5? I would like just to confirm this figure. And also ask what will be the internal Stage 1 guidance or targets that you would like to maintain in the coming years to comply with Basel III standards, considering that peers have Stage 1 ratios around 12%?
And my second question is regarding the spin off of BAC, considering that you already requested the suspension of the trading of [BAC Holding] stocks, Aval and Bogota, in the next week. And we -- I guess, if we have more information regarding the exact number of shares that BAC Holding International will have and also the exchange terms between those investors that will have shares of Sociedad Beneficiaria Aval and Sociedad Beneficiaria Bogotá in the final shares of BAC Holding International. And that will be my 2 questions.
Diego Fernando Solano Saravia - CFO
Okay. Starting with your question on capital ratio, as I mentioned, in absence of what is going on in the market and the OCI and the operational risk that we discussed before, what we would be seeing is something in the order of 130 overall improvement, something perhaps in a similar ratio, 120 to 130 could be happening in core equity Tier 1. However, the things that I mentioned before do affect the ratio. The OCI affects directly core equity Tier 1 as it's a lower number on equity. Therefore, it's a lower number on core equity Tier 1. And then ratio-wise, the increase in risk-weighted assets also puts pressure on that number.
What we expect to see is some slighter improvement when you compare to December -- still an improvement or something of the same order of magnitude from a combination of the positive effects from the spin off and the negatives that I mentioned before. The number that you will see falling is the AT1 bucket because immediately after the spin off that number goes away. And when you think of total solvency, the total solvency in our numbers should look similar to the number that we are reporting on this call.
You also mentioned a comparison to peers. That's actually a moving target at this point. We said at Banco de Bogota, we're not distributing dividends, but for example, our closest peer is just trading around 70% of equity. So that's going to be somehow a lever on how the comparison looks like. So we have to see how the rest of the numbers move on to try to give you further guidance on what our longer-term view on core equity Tier 1 looks like.
Then moving to your second question, I think it's already public with what we've done yesterday. But the logic that we followed here is when we -- or this has been public for some time. When we spun off -- when we're going to spin off the BHI from Banco de Bogota, the company that receives those shares will issue each shareholder of Banco de Bogota a share for each share that they have at Banco de Bogota. Then you repeat the same logic at the level of Aval where the shareholders of Aval will get a share in each one in the recipient company as they have at Aval. However, you're absolutely right, the numbers of shares of Aval and of Banco de Bogota and of BHI are different.
So in the process of merger, we have to normalize that, and the plan that we have is to normalize it around the number of shares of Aval, building up in proportion to that to come up with the number of shares of BHI. So if you're a shareholder of Aval currently, what you should expect to see is to receive a share of the new company after the spin off and the merger happens.
Luis Carlos Sarmiento Gutierrez - President
When you normalize the numbers and you take the largest common denominator to do that, the number of shares in BHI is going to be like about 42 billion shares.
Operator
Our next question comes from Julian Ausique from Davivienda Corredores.
Julian Felipe Ausique Chacon - Equity Analyst
I have 3 questions. And the first one is just like if you can repeat the number that you said of the possible number of shares that BHI will have?
The second one, and it is connected to the third one is the impact that we saw in the quarter in efficiency and in the provision expenses. Because there were an effect -- a negative effect in the efficiency ratio. So I will -- I would like to know if there is -- there will be another provision during this year on this ratio? And in provision expenses, just to understand why the provision expenses like changed a little bit dynamic that we were seeing during the previous quarter that was a decrease in provision expenses. But during the fourth quarter, there was an increase.
Diego Fernando Solano Saravia - CFO
Okay. Regarding the efficiency ratio, we had -- you had 2 questions, efficiency and then cost of risk. Cost of risk, as I mentioned during the presentation, we had some additional overlays basically trying to leave the pandemic behind where we reviewed again all our portfolio, all the sectors and had some overlays that implied slightly higher provisions within actually the guidance that we had done -- given out throughout the year. The way those overlays work -- to make sure that I'm not being too technical here -- is the models automatically were trying to return loans from Stage 2 into Stage 1 given the improvement in performance.
And what we do at that point is we force in certain segments or certain customers based on a regulated logic that is -- that we need to apply there. We force them to stay in Stage 2. Therefore, those that were due perhaps to mechanically lower provision expense did not do it. What we did was basically go through sectors and customers. It's a review that we've been running on a quarterly basis, and we try to have a more stringent one at year-end to, as I said, to try to leave the pandemic behind.
Then efficiency-wise, there is a couple of extraordinary items in expenses that affected our costs during fourth quarter. And in addition, there is a seasonal effect that if you go back into our numbers, you will find systematically where fourth quarter is higher than first quarter, not only in expenses, but also in income, fee income and other sorts of activity because fourth quarter is always a much stronger quarter. That happens in Colombia and much more visible when you look at Central America. The impacts that we had in Colombia were mainly 2: the first one was we made some provisions that go through expenses, provisions related to customers from the mandatory pension funds trying to move into the public pension system outside of regulatory terms -- that -- those are legal processes. And what we've observed historically is they get systematically won by the customers. Therefore, we provision in advance for those legal proceedings. That added to around 120 billion [dollars] in expenses.
And then the other thing that we did in Corficolombiana was given that we are closer to the end of the Pacifico project, we reassessed some of the expenses and included some provisions to cover over -- or cost overruns that we signed a project and that added somewhere between COP 60 billion and COP 80 billion. Those 2 were events in Colombia that add to a seasonally high performance that you can go back in time and check.
Luis Carlos Sarmiento Gutierrez - President
And Julian, to answer your question, I'll repeat the number that I told, Daniel before, that the number of shares of BHI is going to be somewhere around 42 billion shares.

Our next question comes from Nicolas Fabiancic from Jefferies.
Nicolas Fabiancic
I had the same question about the '22's bond. So thanks for that. Just 1 follow-up there would be, if you can comment on any near-term funding needs in the international market or how you're looking at your bond curve, [out of all?] And any color you can share with us about Banco de Bogota would be great.
And then regarding the rating agencies, we see that you're below the Colombia sovereign from Moody's, but flat rating from Fitch. So if you can give us an update there on your conversations with the rating agencies and linkages to the Colombia sovereign, especially considering now that the exposure elsewhere outside of Colombia changes a little bit as a result of the spin off.
Luis Carlos Sarmiento Gutierrez - President
All right, Nicolas. On your first question on the 2022 bonds, I think you said you have that question, but it's been answered. And the answer is, yes, as you said, it stays the same. We are going to pay that one. We don't have any -- right now, any plans to go out at least this year to look for new bonds in the international markets in terms of Aval. In terms of Banco de Bogota. I think that the answer is the same. They would not have to go out in the markets this year.
And regarding the rating agencies, Diego can update you on what conversations we've had with them.
But as a custom what -- at least what I think Moody's does or one of them is that they always assigned Aval a rating one notch below Banco de Bogota as -- have it as a custom. We've always thought against that, but that's what they do. But I don't know if Diego, what conversation...
Diego Fernando Solano Saravia - CFO
I'm actually sorry not to be able to give you any additional color on the connection between the sovereign and our rating beyond what they've done historically, and it is the rating of the country. It does determine or put a ceiling on the rating that we get in the banks. And perhaps we might see a positive year, because in the past, we were getting a double punishment, we were seen based on the Colombian rating. But then if something happened with the ratings in Central America, we got negative effects as we've seen in the past and some of the rating actions have been taken. Over the past years, we did have an effect of the downgrade of Colombia, but most effects were coming actually from Central America from what is happening in each one of the countries.
And we are hopeful that with this separation, we get affected only by the Colombian side, given the much smaller way that the Central American business will get for us. So sorry not to be able to give you something more right on that front, but that's the best that we have.

We have a question from [Jose Cuenca] from Citigroup.
Unidentified Analyst
Just have 2 questions. One related to the guidance. If you could please repeat a couple of items that I couldn't really hear. With regard to the NIM range that you're expecting for Aval and the fee income and nonfinancial sector figures, please?
And the second question is really just a follow-up with regards to what was talked about related to provisions. Just wondering what coverage level are you -- would you be comfortable with in 2022 considering the sectors or the drivers of loan growth? Could we expect something to current levels of coverage?
Diego Fernando Solano Saravia - CFO
Well, I'm going to try not to go again over the whole guidance for the benefit of the rest of the participants in the call. However, I'm going to go back to what I said on NIM. And NIM, we expect to see something in the 4.3% to 4.5% range with loans in the 5.4% to 5.6% range. Implicit in those numbers is something neutral perhaps for investments. You were also asking on cost of risk. What we expect to see in cost of risk is to be in the 1.6% area. Last quarter was in the 1.9% area, and that ties to our view of improvement or good performance of those loans that had relief and have been performing properly.
Regarding coverage, coverage is something that moves depending on different conditions. At this point, part of what we still might have to do into the following quarters is as the loans from the pandemic relief either improve or go sour, we should be writing off some of those and that will move our coverage ratio. However, to give you an idea, our coverage ratio has been pretty stable -- let's say, somewhere around 1.5% to 1.7% area of 90-day PDLs, and that's a reasonable range to look into.

And we have no further questions at this time. I will turn the call over to Mr. Sarmiento Gutierrez for his final remarks.
Luis Carlos Sarmiento Gutierrez - President
Hilda, thank you very much and help -- and thank you to everybody who's on the call and who's been on the call. We will continue to try to deliver for you guys. And after the spin off, we'll see what guidance we can continue giving you on BHI. We'll have to see what guidance we can give. And -- but we will definitely continue giving you guidance on the continued operations. So with that, I leave you. Thank you again. And as always, our phones are open. And if you need to ask any additional questions that we can share with you, we'll be more than happy to do so. And we'll see you in a quarter, I guess. Thank you very much again.
Operator
Thank you. Ladies and gentlemen, this concludes today's conference. We thank you for participating. You may now disconnect.
